Description

Technical Field

[0001] This application relates to the field of electric vehicle lock technology, and in particular to a wireless seat lock. Background Technology

[0002] Electric vehicles are a common mode of transportation in people's daily lives. They are equipped with storage compartments under the seat for users to place items. To improve the anti-theft factor, seat locks are used to lock the seat.

[0003] Common seat locks are connected to the electric vehicle's instrument panel via circuitry on a circuit board, allowing the instrument panel to better monitor the seat lock's status. However, the circuitry on the circuit board is often connected to the instrument panel via soldered flexible wires. At the same time, the flexible wires also need to be connected to the drive unit inside the seat lock. When the flexible wires are installed on the seat lock, they are soldered onto the circuit board, resulting in low assembly efficiency and low connection stability for the seat lock. Utility Model Content

[0004] To facilitate the production of seat locks and improve their stability, this application provides a wireless seat lock.

[0005] This application provides a wireless seat lock, which adopts the following technical solution:

[0006] A wireless seat lock includes a housing, a locking mechanism disposed within the housing, and a circuit board. The locking mechanism is electrically connected to the circuit board, and the circuit board has a connector and a slot for the connector to be inserted into. The connector is electrically connected to the circuit board and is used for electrical connection with an electric vehicle instrument panel.

[0007] By adopting the above technical solution, the connector is directly plugged into the circuit board without soldering. It connects directly to the instrument without the need for a flexible wire, resulting in good stability, convenient assembly and production of the seat lock, and improved stability.

[0008] Optionally, the locking mechanism includes a lock hook and a drive mechanism for rotating the lock hook; it also includes a limit switch assembly electrically connected to a circuit board, the limit switch assembly being used to detect whether the lock hook has rotated to the locked position or the unlocked position.

[0009] By adopting the above technical solution, the unlocking or unlocking status of the seat lock is monitored through the limit switch assembly, so that the instrument can display the seat lock status in a timely manner. The structure is simple.

[0010] Optionally, the limit switch assembly includes a limit switch body, a pressing block, and a compression spring. The limit switch body is electrically connected to a circuit board. The housing has a through hole for the pressing block to slide. The pressing block slides along the length of the through hole. The compression spring is disposed in the through hole. The compression spring drives the pressing block to protrude from the surface of the housing. When the locking hook rotates to cover the through hole and drives the pressing block to retract into the through hole, the pressing block opens the limit switch body. When the compression spring drives the pressing block to protrude from the surface of the housing, the pressing block closes the limit switch body.

[0011] By adopting the above technical solution, the pressing block protrudes from the surface of the housing through the compression spring. When the locking hook rotates and causes the pressing block to retract into the through hole, the limit switch is activated and the instrument displays the seat lock status. When the locking hook moves away from the through hole and the pressing block protrudes from the surface of the housing, the limit switch is closed and the instrument can display the seat lock status in a timely manner.

[0012] Optionally, the limit switch assembly includes a limit switch body, a pressing block, and a compression spring. The limit switch body is electrically connected to a circuit board. The housing has a through hole for the pressing block to slide. The pressing block slides along the length of the through hole. The compression spring is disposed in the through hole. The compression spring drives the pressing block to protrude from the surface of the housing. When the locking hook rotates to cover the through hole and drives the pressing block to retract into the through hole, the pressing block closes the limit switch body. When the compression spring drives the pressing block to protrude from the surface of the housing, the pressing block opens the limit switch body.

[0013] By adopting the above technical solution, the pressing block protrudes from the surface of the housing through the compression spring. When the locking hook rotates and causes the pressing block to retract into the through hole, the limit switch is closed and the instrument does not display the seat lock status. When the locking hook moves away from the through hole and the pressing block protrudes from the surface of the housing, the limit switch is opened and the instrument displays the seat lock status. The limit switch assembly enables the instrument to display the seat lock status in a timely manner.

[0014] Optionally, a waterproof gasket is fitted onto the pressing block, and a waterproof groove is provided on the housing to accommodate the waterproof gasket.

[0015] By adopting the above technical solution, the waterproof gasket improves the waterproof performance of the limit switch assembly.

[0016] Optionally, the inner wall of the through hole is provided with a plurality of drainage grooves in the circumferential direction. The drainage grooves extend in the vertical direction. When the compression spring drives the pressing block to protrude from the surface of the housing, water is discharged along the drainage grooves.

[0017] By adopting the above technical solution, when the compression spring drives the pressing block to protrude from the surface of the housing, the drainage groove increases the drainage speed.

[0018] Optionally, the drive mechanism includes a motor and a gear set. The motor is housed within the housing and plugged into a circuit board. The input end of the gear set is coaxially fixed to the output end of the motor, and a gear is coaxially fixed to the output end of the gear set. A sliding block is slidably mounted on the housing. The rotation of the rack drives the sliding block to slide. A rotating block is rotatably mounted on the housing, and a tension spring is sleeved on the rotating block. The end of the tension spring away from the rotating block is connected to a lock hook. A fixing block is mounted on the sliding block. When the sliding block slides, the fixing block abuts against the rotating block and drives the rotating block to rotate. When the rotating block rotates, it drives the lock hook to rotate through the tension spring, thus unlocking or locking the seat lock. It also includes a seat lock pull rod, which is slidably mounted on the housing and sleeved on the rotating block. The seat lock pull rod is used to pull the rotating block to rotate.

[0019] By adopting the above technical solution, the motor drives the gear to rotate, and the gear drives the sliding block to slide. The rotating block is mounted on the housing. The sliding block drives the rotating block to rotate. It is connected to the lock hook through the tension spring, which drives the lock hook to rotate, thus unlocking or locking the cushion lock. The rotating block can also be driven to rotate through the cushion lock pull rod. The cushion lock is easy to open and close, has a simple structure, and the sliding block slides stably.

[0020] Optionally, the sliding block has a through groove, the gear is disposed in the through groove, and a rack is disposed in the through groove, the gear meshing with the rack.

[0021] By adopting the above technical solution, the rack is set in the through groove, making the spatial layout more reasonable and the seat cushion lock structure more compact.

[0022] Optionally, the pressing block has an arc surface at the end near the locking hook, and the locking hook has a protrusion. When the locking hook rotates, the protrusion abuts against the pressing block and drives the pressing block to be located in the through hole.

[0023] By adopting the above technical solution, the curved surface and protrusion make it less likely to damage the pressing block when the locking hook abuts against it, and at the same time, the pressing is smoother.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The connector is directly plugged into the circuit board without soldering, and is connected to the instrument via hard wire, which has good stability, makes the seat lock easy to assemble and manufacture, and improves the stability of the seat lock.

[0026] 2. The limit switch assembly enables the instrument to display the seat lock switch status in a timely manner;

[0027] 3. Improve the drainage speed of the pressing block by using a drainage channel. Attached Figure Description

[0035] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] This application discloses a wireless seat lock. (See also...) Figure 1 , Figure 2 The wireless seat lock includes a housing 1, a locking mechanism 2 disposed within the housing 1, and a circuit board 3. The locking mechanism 2 is electrically connected to the circuit board 3. A connector 41 is inserted into the circuit board 3, and a slot 42 is provided on the circuit board 3 for the connector 41 to be inserted into. The connector 41 is electrically connected to the circuit board 3 and is used for electrical connection with the electric vehicle instrument panel.

[0037] Reference Figure 1 , Figure 2 , Figure 3The locking mechanism 2 includes a locking hook 21 and a drive mechanism 22 for rotating the locking hook 21. The wireless seat lock also includes a travel switch assembly 5, which is electrically connected to a circuit board 3. The travel switch assembly 5 is used to detect whether the locking hook 21 has rotated to the locked position or the unlocked position. The travel switch assembly 5 includes a travel switch body 51, a pressing block 52, and a compression spring 53. The travel switch body 51 is electrically connected to the circuit board 3. A through hole 43 is provided on the housing 1 for the pressing block 52 to slide along the length of the through hole 43. The compression spring 53 is disposed within the through hole 43, with one end abutting against the bottom of the housing 1 and the other end abutting against the pressing block 52. The spring force direction of the compression spring 53 is parallel to the sliding direction of the pressing block 52, and the compression spring 53 drives the pressing block 52 to protrude from the surface of the housing 1. When the locking hook 21 rotates to cover the through hole 43 and drives the pressing block 52 to retract into the through hole 43, the pressing block 52 opens the limit switch body 51. When the compression spring 53 drives the pressing block 52 to protrude from the surface of the housing 1, the pressing block 52 closes the limit switch body 51.

[0038] Reference Figure 1 , Figure 3 , Figure 4 A waterproof gasket 61 is fitted onto the pressing block 52, and a waterproof groove 62 is provided on the housing 1 to accommodate the waterproof gasket 61. Several drainage grooves 63 are circumferentially arranged on the inner wall of the through hole 43, extending vertically. When the compression spring 53 drives the pressing block 52 to protrude from the surface of the housing 1, water is discharged along the drainage grooves 63. An arc surface 91 is fixed to the end of the pressing block 52 near the locking hook 21, and a protrusion 92 is fixed to the locking hook 21. When the locking hook 21 rotates, the protrusion 92 abuts against the pressing block 52 and drives the pressing block 52 to be positioned within the through hole 43.

[0039] Reference Figure 1 , Figure 2 , Figure 6The drive mechanism 22 includes a motor 221 and a gear set 222. The motor 221 is fixed inside the housing 1 and plugged into the circuit board 3. The input end of the gear set 222 is coaxially fixed to the output end of the motor 221. A gear 71 is coaxially fixed to the output end of the gear set 222. A sliding block 72 is slidably connected to the housing 1, and a sliding spring 78 is sleeved on the sliding block 72. A receiving groove 79 is provided inside the housing 1 for the sliding spring 78 to be accommodated. When the sliding block 72 slides, the sliding spring 78 is compressed and abuts against the side wall of the receiving groove 79, thereby improving the sliding stability of the sliding block 72. The rack 77 rotates to drive the sliding block 72 to slide. A rotating block 73 is rotatably connected to the housing 1, and a tension spring 74 is sleeved on the rotating block 73. The end of the tension spring 74 away from the rotating block 73 is connected to the locking hook 21. A fixing block 75 is fixed on the sliding block 72. When the sliding block 72 slides, the fixed block 75 abuts against the rotating block 73 and drives the rotating block 73 to rotate. When the rotating block 73 rotates, it drives the locking hook 21 to rotate through the tension spring 74, thus unlocking or locking the cushion lock. The wireless cushion lock also includes a cushion lock lever 8, which is slidably connected to the housing 1 and sleeved on the rotating block 73. The cushion lock lever 8 is used to pull the rotating block 73 to rotate.

[0040] The implementation principle of a wireless seat lock according to an embodiment of this application is as follows: When it is necessary to unlock or lock the seat lock, the motor 221 drives the gear set 222 to drive the gear 71 to rotate, causing the sliding block 72 to slide. The fixed block 75 abuts against the rotating block 73 and drives the rotating block 73 to rotate. The rotating block 73 drives the lock hook 21 to rotate through the tension spring 74, realizing the start or stop of the seat lock. When the lock hook 21 rotates to cover the through hole 43 and drives the pressing block 52 to retract into the through hole 43, the pressing block 52 opens the limit switch body 51. When the spring 53 drives the pressing block 52 to protrude from the surface of the housing 1, the pressing block 52 closes the limit switch body 51. The limit switch enables the instrument to display the seat lock status in time. The plug 41 is directly plugged into the circuit board 3, and the plug 41 does not need to be soldered to the circuit board 3. The plug 41 can be directly connected to the instrument without the need for a flexible wire connection, which has good stability. At the same time, the motor 221 is also plugged into the circuit board 3, making the seat lock easy to assemble.

[0041] Reference Figure 5 The difference between this embodiment and embodiment 1 is that when the locking hook 21 rotates to cover the through hole 43 and drives the pressing block 52 to retract into the through hole 43, the pressing block 52 closes the limit switch body 51. When the compression spring 53 drives the pressing block 52 to protrude from the surface of the housing 1, the pressing block 52 opens the limit switch body 51.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
