[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0023] Reference Figure 1-5 As shown,

[0024] A new type of seat cushion lock includes a shell 1, a locking structure 2 arranged in the shell 1, and a pull rod 3 connected to the locking structure 2, wherein the pull rod 3 pulls the locking structure 2 to unlock, and a stabilizing seat 4 is arranged on the pull rod 3, and the stabilizing seat 4 includes a base plate 41 and a cover plate 42, and the pull rod 3 is located between the base plate 41 and the cover plate 42; the base plate 41 and / or the cover plate 42 are provided with a protrusion 43 at a position corresponding to the pull rod 3, and the protrusion 43 is used to abut the pull rod 3, and the base plate 41 is fixedly connected to the shell 1 or the outside through a connecting piece 6.

[0025] First of all, it should be noted that there are already many mature solutions for the locking structure 2 of the seat cushion lock. This improvement is mainly to change the stable structure of the pull rod 3. The specific locking structure 2 can follow the current mature existing technology, such as the locking structure 2 used in the existing technology with patent announcement number CN212290118U. In order to make the activity stability of the pull rod 3 better, this solution sets a stable seat 4 on the pull rod 3 to make the activity of the pull rod 3 more stable. The base plate 41 and the cover plate 42 are installed in coordination and can be installed on both sides of the pull rod 3. At this time, the pull rod 3 is located between the base plate 41 and the cover plate 42, thereby forming a limit, and the protrusions 43 on the base plate 41 and the cover plate 42 can abut against the pull rod 3, making the pull rod 3 less likely to loosen. The number of protrusions 43 can be one, which is set on one of the base plate 41 or the cover plate 42, or multiple, which are all set on one of the base plate 41 or the cover plate 42, or they can be set on the base plate 41 and the cover plate 42 respectively. Refer to the attached figure of this solution. Figure 4 and 5As shown in the figure, there are two protrusions 43, which are respectively located on the base plate 41 and the cover plate 42, and both abut against the pull rod 3 to achieve better stabilization. The base plate 41 can be fixed to the car seat through the connecting member 6 or to the car interior surface or other locations of the car for mounting components, or can be directly installed on the housing 1 of the new seat lock through the connecting member 6, which can further facilitate installation. When installing the new seat lock, only the housing 1 needs to be installed.

[0026] The end of the protrusion 43 may be arc-shaped, which can reduce the contact area with the pull rod 3. Since the locking mechanism is switched by rotation when unlocking and locking, the pull rod 3 will have a certain degree of swing. The arc-shaped protrusion 43 can allow swinging to avoid the pull rod 3 from being stuck. In particular, there are two protrusions 43, which are respectively located on the base plate 41 and the cover plate 42, and the positions correspond to each other.

[0027] In order to facilitate the movement of the pull rod 3 , the cover plate 42 is provided with a groove 421 for accommodating the pull rod 3 and passing through the pull rod 3 , and the protrusion 43 is located at a position corresponding to the groove 421 on the base plate 41 or at a position corresponding to the pull rod 3 on the inner wall of the groove 421 .

[0028] Reference Figure 1 and 4 As shown in , both ends of the groove 421 are connected, that is, connected along the extension direction of the pull rod 3, so that the pull rod 3 can be accommodated and have a better activity space. The protrusion 43 abuts against the pull rod 3, so that the pull rod 3 can be in a stable activity state and is not easy to swing, thereby reducing collision noise and loose feel, and improving user experience.

[0029] The base plate 41 and the cover plate 42 can be made of plastic material, and the connector 6 can be made of metal material. The friction sound between the base plate 41 and the cover plate 42 made of plastic material and the pull rod 3 is light, no harsh friction noise is generated, and the production cost is low. However, in order to further improve the strength of the cover plate 42, a reinforcing rib 422 is provided between two adjacent inner walls in the groove 421.

[0030] Reference Figure 2 As shown in , the reinforcing ribs 422 can improve the strength of the cover plate 42, especially the cover plate 42 with the groove 421 structure and the cover plate 42 supported by plastic material.

[0031] In a further optimization of the reinforcing rib 422, the reinforcing rib 422 is located on the side of the pull rod 3, and forms an inclined surface corresponding to one side of the pull rod 3.

[0032] The reinforcing ribs 422 constituting the inclined surface can play a guiding role when installing the base plate 41 and the cover plate 42 , making it easier to install the base plate 41 and the cover plate 42 without being stuck by the pull rod 3 .

[0033] In the specific setting, the pull rod 3 includes a connecting section 31, a bending section 32, and an operating part 33. The connecting section 31 is connected to the locking structure 2, and the bending section 32 is connected between the connecting section 31 and the operating part 33; the connecting section 31 is located between the base plate 41 and the cover plate 42, and a limiting groove 423 is provided on the cover plate 42 at a position corresponding to the bending section 32, and the bending section 32 moves in the limiting groove 423 to limit the swing of the bending section 32.

[0034] Reference Figure 4 As shown in the figure, the connecting section 31 is a section extending after being connected to the locking structure 2, and is stabilized by cooperating with the base plate 41, the cover plate 42 and the protrusion 43. The bending section 32 is used to transition to the operating portion 33. The bending section 32 cooperates with the limiting groove 423, which can allow the limiting groove 423 to further stabilize the pull rod 3. Since the limiting groove 423 is located on the surface of the cover plate 42, it is used for the bending section 32 to move, so as to Figure 4 Taking the middle angle as an example, the protrusion 43 can form upper and lower limits, and the limit groove 423 forms front and rear limits, thereby making the activity of the pull rod 3 more stable. The operating part 33 can be a part directly used for the user to pull, or a part used to cooperate with an external structure for installation.

[0035] In addition, in a further configuration, the opening of the limiting groove 423 corresponds to the side of the cover plate 42, and the bending section 32 enters the limiting groove 423 through the opening; the groove walls on both sides of the limiting groove 423 are inclined to form a guiding inclined surface 424, and the limiting groove 423 forms a flaring structure through the guiding inclined surface 424.

[0036] First, the opening of the limiting groove 423 corresponds to the side of the cover plate 42, which refers to the side of the cover plate 42 along the moving direction of the bending section 32, and can allow the bending section 32 to enter. The limiting groove 423 forms an expansion structure through the guiding inclined surface 424, which can allow the bending section 32 to enter the limiting groove 423 with a guiding effect, has a stable limiting effect in the locked state, and has a certain degree of limiting when pulling, and has a certain degree of slight activity space, but does not form swinging, which can make the activity smoother.

[0037] In addition, a convex edge 425 is provided on the cover plate 42 corresponding to the edge of the limiting groove 423 , and the convex edge 425 protrudes along the bending section 32 on the surface of the cover plate 42 , and the convex edge 425 is connected with the inner wall of the limiting groove 423 .

[0038] Reference Figure 1 , 2As shown in FIGS. 3 and 4, the convex edge 425 can increase the interaction area with the bending portion, and the limiting effect is better and more stable. It should also be noted that the connection between the convex edge 425 and the inner wall of the limiting groove 423 means that the side of the convex edge 425 corresponds to the inner wall of the limiting groove 423 in a continuous transition state, which is a smooth transition state.

[0039] In order to further reduce the friction noise, the pull rod 3 is covered with a heat shrink tube 5 at the position corresponding to the base plate 41 , the cover plate 42 , the limiting groove 423 , and the protrusion 43 .

[0040] The heat shrink tube 5 contacts the substrate 41 , the cover plate 42 , the limiting groove 423 and the protrusion 43 , thereby reducing friction noise and providing a better user experience.

[0041] In a preferred solution, the base plate 41 is connected to the housing 1 through the connecting member 6, and the base plate 41 is located between the connecting member 6 and the cover plate 42, and the three are fixed by bolts. This structure is simple and easy to install.

[0042] The cover plate 42 is provided with a positioning protrusion 426 at a position corresponding to the base plate 41, and the base plate 41 is provided with a through hole 411 at the position corresponding to the positioning protrusion 426 and adapted to the positioning protrusion 426, and the cover plate 42 is provided with a threaded hole 7 at a position corresponding to the positioning protrusion 426 and used to cooperate with bolts to fasten the connecting piece 6, the base plate 41 and the cover plate 42.

[0043] The positioning protrusion 426 can be positioned in conjunction with the through hole 411, so that the protrusion 43 on the base plate 41 and the protrusion 43 on the cover plate 42 correspond to each other, and the abutment effect on the pull rod 3 is better. In addition, the threaded hole 7 is located at the position of the positioning protrusion 426, which is equivalent to increasing the strength of the connection between the cover plate 42 and the bolt, and at the same time, the base plate 41 can be used to limit the deformation of the positioning protrusion 426, thereby further improving the stability of the assembly.

[0044] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
