Description

Technical Field

[0001] This utility model relates to the field of electric vehicle parts technology, and in particular to an opening device for a seat lock. Background Technology

[0002] With economic development, electric vehicles have become an important means of transportation for people's daily travel. The opening method of electric vehicle seats has become a common concern. Currently, most electric vehicles use mechanical seat lock plates or integrated motor electronic lock plates. The former can only be opened with a mechanical key, while the latter can be opened with a single electronic button. However, the opening device of these seat locks is an integrated structure with the seat lock itself, meaning it can only be used on a single model, is specific to a particular vehicle, has limited compatibility with different models, and is highly restrictive. Users cannot select and install it according to their needs, resulting in poor versatility. Utility Model Content

[0003] The purpose of this utility model is to provide an opening device for a seat lock, thereby solving the technical problem that the opening device for a seat lock in the prior art is an integral structure with the seat lock, which can only be used for a single model and has poor versatility. The various technical effects of the preferred technical solution provided by this utility model are detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This utility model provides a seat lock opening device, including a housing, a sliding block, and an elastic body. One end of the sliding block is provided with a front locking cable connected to a mechanical lock, and the other end is provided with a rear locking cable connected to a lock plate. The housing is provided with a slide rail, allowing the sliding block to slide within the slide rail. An elastic body is provided between the slide rail and the sliding block to keep the rear locking cable taut. The housing also contains a driving assembly for pushing the sliding block to slide within the slide rail.

[0006] Preferably, the housing is provided with a partition plate, which divides the space inside the housing into a power space and a sliding space.

[0007] Preferably, the driving component includes a motor, a gear set, and an eccentric wheel. The motor and the gear set are installed in the power space. The motor drives the gear set to rotate. The eccentric wheel is installed in the sliding space and at the output end of the gear set. The side of the eccentric wheel abuts against the side wall of the sliding block, and the eccentric wheel pushes the sliding block to move.

[0008] Preferably, the sliding block is provided with a cavity, and the front locking cable and the rear locking cable are each provided with a first protrusion that is engaged in the cavity for motion transmission. The two ends of the cavity are provided with a first opening for the front locking cable and the rear locking cable to pass through.

[0009] Preferably, both the front locking cable and the rear locking cable include a pull cord and a connecting sleeve, with the pull cord passing through the connecting sleeve and its two ends connected to the first protrusion.

[0010] Preferably, a limiting block is provided inside the housing, and the limiting block abuts against the eccentric position of the eccentric wheel to limit the position of the eccentric wheel.

[0011] The technical solution provided in this application document has the following beneficial effects:

[0012] This utility model provides an opening device for a seat lock, including a housing, a sliding block, and an elastic body. One end of the sliding block is provided with a front locking cable, which is connected to a mechanical lock, and the other end is provided with a rear locking cable, which is connected to a lock plate. In this way, the opening device for the seat lock is set separately from the seat lock, so that any type of seat lock can be connected to the opening device, which solves the limitations of the opening devices for seat locks in the prior art and ensures universality. Specifically, to facilitate the sliding of the sliding block, a track is provided on the housing, allowing the sliding block to slide within the track. An elastic body is provided between the track and the sliding block to keep the rear lock cable taut. Since the rear lock cable is connected to the lock plate, when the mechanical lock is opened, pulling the front lock cable causes the elastic body to store elastic force, which in turn moves the lock plate by driving the rear lock cable, thus opening the lock body. When the mechanical lock releases the front lock cable, the sliding block returns to its first position under the elastic force stored in the elastic body. The first position of the sliding block is the position of the sliding block in the figure. A drive component is also provided inside the housing to push the sliding block to slide within the track, thereby achieving electric drive unlocking. This achieves two scenarios for opening the lock plate. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] This specific embodiment provides a seat lock opening device, which solves the technical problem that the existing seat lock opening device is an integral structure with the seat lock, which can only be used for a single model and has poor versatility.

[0021] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the following embodiments are not limited to those necessary for the solution of the utility model as described in the claims.

[0022] Reference Figures 1-4This utility model provides an opening device for a seat lock, including a housing 1, a sliding block 2, and an elastic body 3. One end of the sliding block 2 is provided with a front locking cable 4, which is connected to a mechanical lock, and the other end is provided with a rear locking cable 5, which is connected to a lock plate. In this way, the opening device for the seat lock is set separately from the seat lock, so that any type of seat lock can be connected to the seat lock opening device, which solves the limitations of the opening device for seat locks in the prior art and ensures universality. Specifically, to facilitate the sliding of the sliding block 2, a slide rail 11 is provided on the housing 1, allowing the sliding block 2 to slide within the slide rail 11. An elastic body 3 is provided between the slide rail 11 and the sliding block 2 to keep the rear lock cable 5 in a taut state. Since the rear lock cable 5 is connected to the lock plate, when the mechanical lock is opened, the front lock cable 4 is pulled, and the elastic body 3 accumulates elastic force. Simultaneously, by driving the rear lock cable 5, the lock plate is moved, thereby opening the lock body. When the mechanical lock releases the front lock cable 4, the sliding block 2 returns to its first position under the action of the elastic force accumulated in the elastic body 3. The first position of the sliding block 2 is... Figure 2 The sliding block is positioned such that a drive assembly is also provided inside the housing 1 to push the sliding block 2 to slide within the slide rail 11, thereby achieving electric unlocking. This enables two ways to open the lock plate. For convenient power supply, the drive assembly can be electrically connected to the battery on the tram.

[0023] To further optimize the design and make reasonable use of space, a partition plate 13 is provided inside the housing 1. The partition plate 13 divides the space inside the housing 1 into a power space and a sliding space. Specifically, the motor of the drive device is installed in the power space, and the sliding block 2 is set in the sliding space. When the sliding block 2 moves, the probability of collision with the motor of the drive component is reduced.

[0024] The scheme is further optimized. The drive component includes a gear set and an eccentric wheel 6. The eccentric wheel 6 is installed at the output end of the gear set. The motor and gear set are installed in the power space. The eccentric wheel 6 is installed in the sliding space. The output end of the gear set passes through the partition plate 13 and is connected to the eccentric wheel 6. The side of the eccentric wheel 6 abuts against the side wall of the sliding block 2. That is, the motor drives the gear set to rotate, so as to drive the eccentric wheel 6 to rotate forward or backward. The eccentric wheel 6 pushes the sliding block 2 to move. Similarly, when the eccentric wheel 6 rotates, the elastic body 3 repeatedly accumulates and releases elastic force, so that the sliding block 2 always abuts against the eccentric wheel 6, so as to facilitate the movement of the locking plate.

[0025] To further optimize the design, in order to facilitate the installation of the front locking cable 4 and the rear locking cable 5, a cavity 21 is provided on the sliding block 2. Both ends of the front locking cable 4 and the rear locking cable 5 are provided with a first protrusion 22, which can be placed in the cavity 21. The two ends of the cavity 21 are provided with a first opening for the front locking cable 4 and the rear locking cable 5 to pass through. This not only facilitates the installation of the front locking cable 4 and the rear locking cable 5, but also reduces the weight of the sliding block 2 and facilitates the sliding of the sliding block 2.

[0026] The design is further optimized so that both the front lock cable 4 and the rear lock cable 5 include a pull cord 451 and a connecting sleeve 452. The pull cord 451 passes through the connecting sleeve 452 and both ends and is connected to the first protrusion 22. Specifically, the connecting sleeve 452 has a through hole, and the pull cord 451 passes through the through hole. This can extend the service life of the pull cord 451 and reduce the chance of people being scratched. The first protrusion 22 is installed at both ends of the pull cord 451. When unlocking, only the pull cord 451 needs to be moved.

[0027] To further optimize the design, in order to facilitate the limitation of the position of the eccentric wheel 6, a limiting block 7 is set inside the housing 1. The limiting block 7 abuts against the eccentric position of the eccentric wheel 6 to limit the position of the eccentric wheel 6. When the motor rotates in the forward or reverse direction, the eccentric position of the eccentric wheel 6 abuts against the limiting block 7, so that the sliding block 2 achieves one reciprocating motion and avoids back-and-forth sliding.

[0028] To further optimize the design, in order to facilitate the limiting of the connecting sleeve 452, a second opening 12 is provided on the housing 1, and at least two annular protrusions 453 are provided on the outer periphery of the connecting sleeve 452. There is a gap between the two annular protrusions 454. The gap between the two annular protrusions 453 is engaged in the housing 1 through the second opening 12, so that one annular protrusion 453 is installed inside the housing 1 and the other annular protrusion 453 is installed outside the housing 1. This facilitates the limiting of the position of the connecting sleeve 452 and also facilitates the connection with the mechanical lock.
