The bottom edge of first inner rail side wall 122 is connected to the bottom edge of fourth inner rail side wall 125 by a first inner rail connection 126, and the bottom edge of third inner rail side wall 124 is connected to the bottom edge of second inner rail side wall 123 by a second inner rail connection wall 127.
In the assembled state, the first inner rail side wall 122 and the second inner rail side wall 123 are located between the second outer rail side wall 113 and the fourth outer rail side wall 115. The third inner rail side wall 124 is located between the first outer rail side wall 112 and the second outer rail side wall 113, and more specifically, the third inner rail side wall 124 is located in the first outer rail cavity, and the third inner rail side wall 124 and the cavity wall of the first outer rail cavity together enclose a roller raceway. The fourth inner rail side wall 125 is located between the third outer rail side wall 114 and the fifth outer rail side wall 115, and more specifically, the fourth inner rail side wall 125 is located within the second outer rail cavity and cooperates with the cavity wall of the second outer rail cavity to define a roller raceway.
More specifically, the second connecting wall 117 is lower than the second connecting wall 116, and thus is provided to provide an installation space for the lock pin 21 of the locking assembly 2.
Specifically, as shown in fig. 2 and 4, the locking assembly 2 includes a lock pin 21 and a spring 22. The lock pin 21 is provided with a first step surface 212 and a second step surface 213 on the outer periphery.
As shown in fig. 3 and 4, in the assembled state, the lock pin 21 extends in the horizontal direction, the first step surface 212 is located outside the inner rail cavity, the second step surface 213 and the spring 22 are located inside the inner rail cavity, the spring 22 is pre-compressed between the first step surface 212 and the first inner rail side wall 122, and the lock pin 21 moves in the direction approaching the second outer rail side wall 113 under the elastic force of the spring 22. In the locked state, the lock pin 21 passes through the first inner rail side wall 122, the second inner rail side wall 123, and the second outer rail side wall 113 in this order.
Since no other parts are basically arranged on the side wall of the inner rail 12, the problem that the lock pin 21 interferes with other parts of the slide rail 1 due to the fact that the lock pin 21 extends in the horizontal direction can be avoided, and the lock pin 21 is more convenient to assemble.
Preferably, the spring 22 is a conical coil spring, that is, the outer peripheral surface of the spring 22 coincides with a conical surface. When the spring 22 is compressed, the end with the smaller size can be embedded into the surrounding space of the end with the larger size, so that the space of the inner rail cavity can be saved. Moreover, the spring 22 has good processing technology.

The lock pins 21 of each set of locking assemblies 2 are sequentially arranged at intervals along the length direction of the inner rail 12. In the figure, each set of locking assemblies 2 includes six lock pins 21, and in specific implementation, the number of the lock pins 21 of each set of locking assemblies 2 can be flexibly set according to actual needs, and the interval between adjacent lock pins 21 can be set according to the step pitch of the inner rail 12. By reasonably setting the number of the lock pins 21 and the interval between the lock pins 21, the lock pins 21 can penetrate into the second outer rail side wall 113 of the outer rail 11 when the inner rail 12 is at any position.
Preferably, as shown in fig. 4 and 5, the lock pin 21 is provided with a locking groove 211 on the periphery. During the application of the seat track assembly, the engaging groove 211 is located between the second outer track sidewall 113 and the second inner track sidewall 123. Before the automobile seat slide rail assembly is applied, an impact test is generally required to be carried out so as to verify the locking performance of the locking component 2. In the test process, the clamping groove 211 is clamped on the second outer rail side wall 113, so that the problem that the test is smoothly carried out due to the fact that the lock pin 21 is separated from the second outer rail side wall 113 in the test process can be solved.

When the unlocking fork 33 rotates, the fork arm 331 can abut against the first step surface 212, so as to abut against the lock pin 21 to be disengaged from the second outer rail side wall 113, and unlocking of the outer rail 11 and the inner rail 12 is realized. Therefore, the unlocking shifting fork 33 can shift the lock pin 21 without extending into the inner rail cavity, and compared with the situation that the unlocking shifting fork 33 extends into the inner rail cavity, the assembly is simpler and more convenient.
More specifically, the fixing bracket 31 has a horizontal top plate 311 and two side plates 312, top edges of the two side plates 312 are respectively connected to two sides of the horizontal top plate 311, bottom edges of the two side plates 312 are respectively provided with a horizontal hole plate 313, side edges of the two side plates 312 are respectively provided with a vertical hole plate 314, the two horizontal hole plates 313 are fixedly connected to the horizontal top wall 121 of the inner rail 12, and the rotating shaft 32 extends along the length direction of the inner rail 12 and penetrates through connecting holes of the two vertical hole plates 314. The fixing bracket 31 with the structure can be directly formed by punching, is simple and convenient to process and has high structural strength. Of course, the structure of the fixing bracket 31 is not limited to this.
More specifically, the yoke 331 of the unlocking fork 33 is provided at a lower portion of the body of the unlocking fork 33, and an upper portion of the body of the unlocking fork 33 is bent in a direction away from the first step surface 212 to form a bent portion 332, and the bent portion 332 extends between the horizontal top wall 121 and the horizontal top plate 311. An ear plate is arranged in the middle of the main body of the unlocking shifting fork 33, and the rotating shaft 32 penetrates through an ear hole of the ear plate. With this arrangement, when the bent portion 332 is pressed downward, the yoke 331 of the unlocking fork 33 can move in a direction approaching the first step surface 212, and can push the lock pin 21 out of the second rail side wall 113. It can be seen that, when the arrangement is such that the unlocking component 3 can be driven to unlock only by pressing the bent portion 332 downwards by the manipulating component 4, the arrangement of the manipulating component 4 is facilitated.
More specifically, as shown in fig. 1, the operating assembly 4 includes two pressing arms 41, one pressing arm 41 is responsible for pressing against the unlocking assembly 3 mounted on one set of slide rails 1, and the other pressing arm 41 is responsible for pressing against the unlocking assembly 3 mounted on the other set of slide rails 1.
