[0002] The main function of rear seat locks in cars is to control the folding and locking of the seats, ensuring passenger safety and comfort. Rear seat locks are typically mechanically controlled, and users can unlock or lock the seats using buttons, levers, or switches.

[0003] In existing seat locks, the buckle on the backrest is manually inserted into the lock's latch to lock the seat. However, if the manual locking is not done properly, the locking status of the seat lock cannot be observed, which can easily cause abnormal noises during driving. Therefore, this paper proposes a new car seat lock to solve the problems of the inability to observe the locking status of the seat lock and the abnormal noises that can easily occur during driving when the manual locking is not done properly.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Please see Figure 1 —5, a car seat lock, comprising a lock body 1 and a cover plate 2, the lock body 1 and the cover plate 2 being connected by a first rivet 3 and a second rivet 4, and further comprising a lock leaf 5, a locking drive 6 and a locking plate 7, a contact switch 8 being fixedly installed on the outer wall of one side of the lock body 1, the lock leaf 5 being rotatably connected to the first rivet 3, the locking drive plate 6 and the locking plate 7 being rotatably connected to the second rivet 4, a sliding rod 71 being provided on the locking plate 7, a first elastic unit 11 being provided between the lock leaf 5 and the lock body 1, and a second elastic unit 12 being provided between the locking drive plate 6 and the lock body 1, one end of the sliding rod 71 being slidably connected to the locking drive 6, and the other end being slidably connected to the cover plate 2, the locking drive 6 driving the locking plate 7 to rotate to one side to abut against the lock leaf 5, and by means of a latch abutting against the lock leaf 5 and driving the lock leaf 5 to rotate, thereby driving the locking plate 7 and the locking drive 6 to rotate, so that the locking plate 7 abuts against the contact switch 8.

[0024] Specifically, such as Figure 1 and Figure 5 As shown, the lock body 1 and the cover plate 2 are fixedly connected by a first rivet 3 and a second rivet 4. A bent portion 23 is provided on the cover plate 2, and a insertion hole is formed in the bent portion 23. A insertion rod 13 is provided on the outer wall of one side of the lock body 1. After the cover plate 2 and the lock body 1 are connected by the first rivet 3 and the second rivet 4, the insertion rod 13 is located in the insertion hole of the bent portion 23. The bent portion 23 increases the strength of the lock body 1 and improves the strength of the cover plate 2. A contact switch 8 is fixedly installed on the outer wall of one side of the lock body 1. The contact switch 8 maintains a signal connection with the vehicle's infotainment system. It should be noted that the structure and principle of the contact switch 8 maintaining a signal connection with the vehicle's infotainment system are conventional techniques in this field and will not be described in detail here.

[0025] As a further embodiment provided by this utility model, such as Figure 5As shown, it also includes a locking leaf 5, a locking drive component 6, and a locking plate 7. The locking leaf 5 is rotatably connected to the first rivet 3, and the locking drive component 6 and the locking plate 7 are both rotatably connected to the second rivet 4. A sliding rod 71 is fixedly installed on the outer wall of the locking plate 7. One end of the sliding rod 71 is slidably connected to the locking drive component 6, and the other end of the sliding rod 71 is slidably connected to the locking plate 7. A first elastic unit 11 is provided between the locking leaf 5 and the lock body 1, and a second elastic unit 12 is provided between the locking drive plate 6 and the lock body 1. Specifically, both the first elastic unit 11 and the second elastic unit 12 are spiral springs. Using spiral springs for the first elastic unit 11 and the second elastic unit 12 makes production and assembly more convenient.

[0026] A plastic coating layer 51 is provided on the outside of the locking leaf 5. During the unlocking and locking process, the plastic coating layer 51 contacts the latch, which can reduce the wear of the latch and prevent the latch from directly contacting the locking leaf 5 and causing abnormal noise. The outer wall of the locking leaf 5 is provided with a first abutment part 52 and a second abutment part 53. Both the first abutment part 52 and the second abutment part 53 can abut against the locking plate 7, thereby realizing the unlocked state and the locked state.

[0027] A first sliding groove 61 is provided on the outer wall of the locking drive component 6, and a second sliding groove 21 is provided on the outer wall of one side of the cover plate 2. Specifically, the first sliding groove 61 is an oval arc groove with a locking position at the end. The second sliding groove 21 is specifically a "V" shaped structure. One end of the sliding rod 71 is slidably connected to the first sliding groove 61, and the other end of the sliding rod 71 is slidably connected to the second sliding groove 21.

[0028] When the locking position on the first sliding groove 61 is in the unlocked state, it can abut against the sliding rod 71. When unlocking is required, the user drives the locking drive plate 6 to rotate by using a lever. At this time, the sliding rod 71 will slide in the first sliding groove 61, which will drive the locking plate 7 to rotate slightly. At this time, the lock leaf 5 will not rotate significantly, thus preventing accidental opening.

[0029] As an embodiment provided by the present invention, such as Figure 3 As shown, a waist-shaped hole 72 is provided on the outer wall of one side of the locking plate 7. The locking plate 7 is rotatably connected to the second rivet 4 through the waist-shaped hole 72. A rotating abutment part 73 is provided on the locking plate 7.

[0030] The locking plate 7 is connected to the second rivet 4 through the oblong hole 72. When the locking drive plate 6 drives the locking plate 7 to rotate via the sliding rod 71, since one end of the sliding rod 71 is slidably connected to the first sliding groove 61 and the other end is slidably connected to the second sliding groove 21, when the first sliding groove 61 on the locking drive plate 6 abuts against the sliding rod 71 and drives the sliding rod 71 to rotate, since the other end of the sliding rod 71 is slidably connected to the second sliding groove 21, the locking plate 7 is again connected to the second rivet 4 through the oblong hole 72. The two rivets 4 are connected, so the locking plate 7 can be driven to slide on the second rivet 4 through the waist-shaped hole 72, so that one end of the sliding rod 71 can slide in the "V"-shaped structure of the second sliding groove 21. The locking plate 7 first moves along one side of the second sliding groove 21. When the locking leaf 5 is separated from the locking plate 7, the locking leaf 5 rotates outward. The abutting block 54 provided on the locking leaf 5 abuts against the abutting rod 14 provided on the lock body 1 to restrict the rotation of the locking leaf 5, so that the locking leaf 5 is in the unlocked state. At this time, the lock can be taken out.

[0031] This utility model uses a first elastic unit 11 to drive the locking drive plate 6 to rotate to one side, the locking drive plate 6 to drive the locking plate 7 to rotate to one side, and a second elastic unit 12 to drive the locking leaf 5 to rotate to one side. The locking leaf 5 and the locking plate 7 rotate towards each other and abut against each other. The locking latch drives the locking leaf 5 to continue rotating, and simultaneously drives the locking plate 7 to abut against the contact switch 8. The contact switch 8 abuts against the locking plate 7 to provide a signal to the vehicle system to monitor whether it is locked, so as to prevent collisions and abnormal noises caused by incomplete locking during driving.

[0032] Working principle:

[0033] In the normal state, when the locking drive 6 drives the locking plate 7 to remain in contact with the locking leaf 5, the first abutting part 52 on the locking leaf 5 abuts against the outer wall of the locking plate 7. The opening of the locking leaf 5 faces outward, allowing the latch to be inserted. When the latch is inserted into the opening on the locking leaf 5, the latch abuts against the plastic coating layer 51 on the outer wall of the locking leaf 5, driving the locking leaf 5 to rotate. Due to the action of the second elastic unit 12, the locking plate 7 abuts against the first abutting part 52 on the locking leaf 5, and the outer wall of the locking plate 7 remains in contact with the outer wall of the locking leaf 5 during the rotation of the locking leaf 5. When the locking leaf 5 rotates to a certain angle, it drives the locking drive plate 6 to rotate under the action of the second elastic unit 12. The locking drive plate 6 drives the locking plate 7 to rotate through the sliding rod 71, and then abuts against the second abutting part 53 provided on the locking leaf 5. The locking plate 7 is driven to rotate through the first abutting part 52 provided on the outer wall of the locking leaf 5, so that the locking plate 7 abuts against the second abutting part 53, and the rotating abutting part 73 on the locking plate 7 abuts against the contact switch 8, triggering the contact switch 8. At this time, a locking signal can be provided to the vehicle system, which is convenient for the driver to observe the vehicle status.

[0034] The first elastic unit 11 and the second elastic unit 12 mentioned in this article have elastic coefficients that meet the technical requirements of the present invention.

[0035] Those skilled in the art will understand that other similar connection methods can also achieve this utility model. For example, welding, bonding, or screwing.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
