In one possible implementation, the first elastic support arm 420 is located at an end of the elastic member 410 facing the rotation shaft assembly 300, and the second elastic support arm 430 is located at an end of the elastic member 410 facing the bracket 500. It will be appreciated that referring to fig. 1 and 2, the elastic member 410 can be stretched or compressed during rotation of the upper liner 211 so that the upper case 210 can be brought into a fully opened or fully closed state. It is understood that the elastic component 400 may be a torsion spring with good elastic force.

With continued reference to fig. 1, on the basis of the above embodiment, a support arm through hole 440 may be further formed in an inner surface of the housing 200 facing away from the rotatable end of the upper housing 210. Wherein, the support arm through hole 440 may be located above the rotation shaft hole 320 from a side view of the housing 200, or the support arm through hole 440 may be located below the rotation shaft hole 320. In an embodiment of the present application, the first elastic support arm 420 may be inserted into the support arm through hole 440.

With continued reference to fig. 1, when the spindle assembly 300 is located above the parting plane 230, the spindle hole 320 may be formed on the inner surface of the upper housing 210, or the spindle hole 320 may be formed on the inner surface of the lower housing 220, and the spindle body 310 is always inserted into the spindle hole 320. In one possible implementation, the support arm through-hole 440 is illustrated above the spindle hole 320. One end of the first elastic supporting arm 420 may be connected to the inner surface of the housing 200 through the supporting arm through hole 440, and the other end of the first elastic supporting arm 420 may be connected to one end of the elastic member 410. Accordingly, one end of the second elastic supporting arm 430 may be connected to the other end of the elastic member 410, and the other end of the second elastic supporting arm 430 may be connected to the bracket 500. In one possible implementation, an end of the support 500 facing the elastic assembly 400 may be provided with a bending portion 510, and the second elastic support arm 430 may be engaged with the bending portion 510, so that, in an embodiment of the present application, the first elastic support arm 420 in the elastic assembly 400 may be fixedly connected to the housing 200 through the support arm through hole 440, and the second elastic support arm 430 may be fixedly connected to the support 500 through the bending portion 510. During rotation of the upper liner 211, the elastic member 400 may be rotated together. Since the support arm through-hole 440 has a certain distance from the rotation shaft hole 320, the elastic member 410 can be stretched or compressed when the upper liner 211 is rotated, so that the upper case 210 can be completely opened or completely closed.

In one possible implementation manner, when the rotating shaft assembly 300 is located above the parting plane 230 and the supporting arm through hole 440 is located above the rotating shaft hole 320, the working state of the elastic member 410 may be changed from the stretched state to the compressed state and finally back to the stretched state when the upper liner 211 rotates from the closed state to the open state. Accordingly, when the hinge assembly 300 is located above the parting plane 230 and the support arm through hole 440 is located below the hinge hole 320, the upper liner 211 rotates from the closed state to the open state, and the working state of the elastic member 410 can be changed from the compressed state to the stretched state and finally returns to the compressed state. In this way, the opening process of the wireless headset charging case 100 can be completed to the maximum.

Referring to fig. 4, when the shaft assembly 300 is positioned below the parting plane 230, the upper liner 211 may have a protrusion 2111 toward one end of the shaft assembly 300 in one possible implementation, based on the above-described embodiment. The shaft hole 320 may be formed on the protrusion 2111 of the upper liner 211, and the shaft body 310 is still inserted into the shaft hole 320. In one possible implementation, taking the example that the support arm through hole 440 is located below the rotation shaft hole 320, the support arm through hole 440 may also be opened on the protrusion 2111 of the upper liner 211. One end of the first elastic supporting arm 420 may be disposed through the supporting arm through hole 440 to be connected to the upper liner 211, and the other end of the first elastic supporting arm 420 may be connected to one end of the elastic member 410. Accordingly, one end of the second elastic supporting arm 430 may be connected to the other end of the elastic member 410, and the other end of the second elastic supporting arm 430 may be connected to the lower liner 221. Thus, in an embodiment of the present application, the first elastic support arm 420 of the elastic assembly 400 may be fixedly coupled to the upper liner 211 through the support arm through hole 440, and the second elastic support arm 430 may be fixedly coupled to the lower liner 221. During rotation of the upper liner 211, the protrusions 2111 may be rotated together, thereby stretching or compressing the elastic member 410. Since the support arm through-hole 440 has a certain distance from the rotation shaft hole 320, the elastic member 410 can be stretched or compressed when the upper liner 211 is rotated, so that the upper case 210 can be completely opened or completely closed.

In one possible implementation manner, when the rotating shaft assembly 300 is located below the parting plane 230 and the supporting arm through hole 440 is located below the rotating shaft hole 320, the working state of the elastic member 410 may be changed from the stretched state to the compressed state and finally back to the stretched state when the upper liner 211 rotates from the closed state to the open state. Accordingly, when the hinge assembly 300 is located below the parting plane 230 and the support arm through hole 440 is located above the hinge hole 320, the upper liner 211 rotates from the closed state to the open state, and the working state of the elastic member 410 can be changed from the compressed state to the stretched state and finally returns to the compressed state. In this way, the opening process of the wireless headset charging case 100 can be completed to the maximum.

With continued reference to fig. 1 and 4, the wireless headset charging case 100 may further include: magnetic attraction member 600. Wherein in one possible implementation, the number of magnetic attractors 600 may be at least two. The application is not limited in this regard to the number of magnetic attractors 600. In the embodiment of the present application, the number of the magnetic attraction pieces 600 is exemplified as two. Two magnetic attraction pieces 600 can be located on an inner surface of the housing 200 facing away from the end of the shaft assembly 300, i.e., one of the magnetic attraction pieces 600 is located at the rotatable end of the upper housing 210 and the other magnetic attraction piece 600 is located in the lower housing 220 at a position corresponding to the magnetic attraction piece 600 in the upper housing 210. In the height direction of the housing 200, two magnetic attraction pieces 600 may be disposed up and down. In one possible implementation manner, each magnetic attraction piece 600 can be located at two ends of the parting plane 230 respectively, and the two magnetic attraction pieces 600 can be magnetically attracted to each other to be matched with each other when the wireless earphone charging box 100 is in an opened or closed state, so that the wireless earphone charging box 100 can realize magnetic attraction of the cover and the cover. In the embodiment of the present application, the magnetic attraction member 600 is provided to improve the holding force of the completely opened and closed cover, so as to avoid shaking of the wireless earphone charging box 100.

Referring to fig. 5, the outer surface of the case 200 may be provided with a charging port 700 on the basis of the above-described embodiment. Wherein, the charging port 700 can be used to charge the wireless earphone charging case 100, and the charging port 700 can communicate the inside with the outside of the wireless earphone charging case 100.

In an embodiment of the present application, the feel of the user's use of the wireless headset charging case 100 is related to the parameters of the elastic member 410 itself.

When the pitch diameter, the wire diameter, the number of turns, the arm of force, the elastic modulus, the tensile strength, and the winding ratio of the elastic member 410 are respectively increased, the torsion force required to open the wireless headset charging case 100 is respectively increased, decreased, increased, unchanged, and decreased, and the life of the elastic member 410 is respectively reduced, decreased, increased, decreased, increased, and increased. Therefore, the user feels different to use the wireless headset charging case 100 under different parameters of the elastic member 410.

In the embodiment of the application, the internal space of the wireless earphone charging box 100 is reasonably utilized, the number of internal parts is reduced, and the process cost is reduced. In addition, by adjusting the parameters of the elastic component 400, the user's use feel is further adjusted, so that the upper housing 210 can rotate around the rotating shaft component 300 in a large range, providing a larger space for the upper housing 210 of the wireless earphone charging box 100, and facilitating the taking of the earphone.
