Description

Technical Field

[0001] This utility model relates to the field of vehicle interior locking structure technology, specifically to a vehicle magnetic locking device. Background Technology

[0002] Currently, various control switches are used in automobiles, such as door locks, trunk locks, and seat back control locks in some models. Existing control lock structures are mainly divided into mechanical locks and electronic locks. Mechanical locks have a relatively simple structure, mainly relying on mechanical components to achieve locking and unlocking actions, and the unlocking process is completed manually. Electronic locks have a relatively complex structure, including mechanical structures, motors, sensors, control modules, and other electronic components. When in use, they achieve automatic locking and unlocking functions through electric control.

[0003] Existing mechanical locks are simple in structure, easy to operate, and low in cost; however, their overall operability is poor, making them unsuitable for some high-end vehicles. While electronic locks offer higher intelligence and better control, their overall structure is complex and more expensive. For seat back panel control locks in high-end vehicles, using a mechanical lock structure is inconsistent with the high-end vehicle positioning. However, the seat back panel is not a critical control object; using an electronic lock structure would increase costs and result in unnecessary waste. Therefore, it is necessary to develop a new control lock structure for unlocking high-end vehicles at a lower cost. Utility Model Content

[0004] The present invention aims to provide a magnetic locking device for vehicles to solve the problem that existing technologies cannot achieve a good unlocking structure with good handling at a low cost.

[0005] To solve the above problems, the present invention adopts the following technical solution: a vehicle magnetic locking device, comprising a first mounting member and a second mounting member, wherein the first mounting member is provided with an insertion hole, and a first magnetic part is fixedly connected in the insertion hole; the second mounting member is slidably connected to a slide block that engages with the insertion hole, and a second magnetic part that magnetically attracts the first magnetic part is fixedly connected to the slide block; a driving mechanism for driving the slide block to slide is connected to the second mounting member; an elastic member is fixedly connected between the second mounting member and the slide block; when the first magnetic part and the second magnetic part are magnetically attracted to each other, the magnetic force between the first magnetic part and the second magnetic part drives the slide block to insert into the insertion hole.

[0006] The principles and beneficial effects of this application are as follows: In this application, the first magnetic part and the second magnetic part can magnetically attract each other. When the first magnetic part is facing the second magnetic part, the magnetic force between the first magnetic part and the second magnetic part drives the slide to insert into the socket. Therefore, under normal circumstances, under the magnetic force of the first magnetic part and the second magnetic part, the slide slides relative to the second mounting member and slides towards the first mounting member, so that the end of the second magnetic part facing the first magnetic part is inserted into the socket of the first mounting member. At this time, the first magnetic part and the second magnetic part attract each other, so that the entire locking device is in a locked state. When unlocking is required, the drive mechanism drives the slide to slide away from the first mounting member. The slide drives the second magnetic part to disengage from the first magnetic part, and the unlocking action is successfully realized. At this time, the first mounting member or the second mounting member can be rotated or moved to complete the opening action, etc.

[0007] After unlocking, the magnetic force weakens significantly as the first and second magnetic parts move further apart. Under the pulling force of the elastic element, the slide is pulled back into the second mounting component. This prevents the slide and its second magnetic part from protruding beyond the second mounting component after unlocking. This avoids damage to the second magnetic part and slide from collisions with other components, and also prevents them from damaging other components (such as the first mounting component). When the first and second mounting components move or rotate to their reset state, the slide re-inserts into the socket under the magnetic attraction of the first and second magnetic parts, locking the first and second mounting components together.

[0008] Therefore, the technical solution of this application offers better control and a more technological feel compared to the existing technology that uses purely mechanical locks. It can be better applied to high-end models. In addition, the locking device in this application has a simple overall structure. By simply setting a first mounting part and a second mounting part, and then setting a first magnetic attraction part and a second magnetic attraction part structure in the first mounting part and the second mounting part, the magnetic attraction locking operation can be easily completed. The overall structure is simple. Compared with the electronic locks of existing car doors and other structures, the structure is relatively simple and the cost is lower. It can be applied to the locking control of the seat back panel, with stable control and a strong sense of operation.

[0009] Preferably, as an improvement, the second mounting member is fixedly connected to a limiting member that cooperates with the slide. When the first magnetic part and the second magnetic part move away from each other, the elastic member pulls the slide to slide until it abuts against the limiting member, and the second magnetic part and the slide slide into the second mounting member.

[0010] In this design, a limiting component is used to limit the sliding of the slide block relative to the second mounting component. When the first and second mounting components are unlocked and moved away from each other, the slide block slides into the second mounting component under the pulling force of the elastic component. Finally, the slide block stops sliding when it comes into contact with the limiting component. At this time, the slide block remains in a tight position against the limiting component under the pulling force of the elastic component. On the one hand, this prevents the slide block from sliding relative to the second mounting component due to centrifugal force when the second mounting component rotates, thus preventing the end of the slide block from protruding beyond the second mounting component and causing damage from collisions with other components (such as the first mounting component). On the other hand, the slide block always comes into contact with the limiting component under the pulling force of the elastic component, preventing the slide block from shaking randomly within the second mounting component and causing abnormal noise, thus improving the comfort during use.

[0011] Preferably, as an improvement, the second mounting component has a sliding groove, and the slide block slides in conjunction with the sliding groove; the slide block has an installation groove, and the drive mechanism is connected to the installation groove.

[0012] The slide groove in this design provides guidance and limit for the sliding of the slide block, enabling the slide block to slide more smoothly, stably and accurately; in addition, a drive mechanism is set in the mounting groove on the slide block, so that the drive mechanism can drive the slide block to slide smoothly. The structure is simple and easy to operate.

[0013] Preferably, as an improvement, the driving mechanism includes a rotating component and a rotating fork fixedly connected to the rotating component. The rotating component is rotatably connected to the second mounting component, and the slide has a paving groove that movably engages with the rotating fork.

[0014] In this design, rotating the rotating component connected to the second mounting component causes the rotating component to drive the rotating fork to rotate relative to the second mounting component. Since the rotating fork is in active engagement with the actuating groove on the slide, the rotating fork can drive the slide to slide when it rotates, thereby accurately completing the unlocking operation. At the same time, since the rotating fork is always inserted into the actuating groove, the rotating fork can limit the slide perpendicular to the sliding direction of the slide, allowing the slide to slide more stably relative to the second mounting component.

[0015] Preferably, as an improvement, the number of rotating forks is two, and the two rotating forks are located on both sides of the rotating component; the number of actuation slots is also two, and the two actuation slots are staggered along the sliding direction of the slide block.

[0016] In this design, two rotating forks are located on both sides of the rotating component. When the rotating component rotates relative to the second mounting component, the two rotating forks simultaneously limit the slide block in the direction perpendicular to the slide block, thereby making the slide block slide more smoothly.

[0017] Preferably, as an improvement, the elastic element includes a tension spring fixedly connected between the second mounting member and the slide.

[0018] In this design, the tension spring is easy to install and can provide stable tension to the slide for a long time.

[0019] Preferably, as an improvement, a first fixing pin is fixedly connected to the second mounting member, a second fixing pin is fixedly connected to the slide, and one end of the tension spring is connected to the first fixing pin and the other end is connected to the second fixing pin.

[0020] In this solution, by setting a first fixing pin and a second fixing pin, the two ends of the tension spring can be hooked onto the first fixing pin and the second fixing pin respectively when installing the tension spring, thus making the tension spring easy and stable to install.

[0021] Preferably, as an improvement, the tension spring, the first fixing pin, and the second fixing pin are all located within the mounting groove.

[0022] In this design, the tension spring, the first fixing pin, and the second fixing pin are all placed in the mounting groove, reducing the space occupied by the components and making the structure more compact. The mounting groove also protects the tension spring, allowing it to work more stably.

[0023] Preferably, as an improvement, the first magnetic attraction part includes a permanent magnet, and the second magnetic attraction part includes an electromagnet that attracts the permanent magnet.

[0024] In actual use, the second mounting component is larger due to the inclusion of tension springs, sliding blocks, and other structures. Therefore, for ease of operation and installation, the second mounting component is usually fixed to the vehicle body, while the first mounting component is connected to the rotating part to be controlled. Thus, in this design, the first magnetic attraction part is set as a permanent magnet, while the second magnetic attraction part is set as an electromagnet, facilitating control of the second magnetic attraction part's energization and making the locking device structure more rational.

[0025] Preferably, as an improvement, the limiting member includes a limiting seat fixedly connected in the slide groove, and a reinforcing rib is fixedly connected between the side of the limiting seat opposite to the second magnetic part and the second mounting member.

[0026] In this design, a reinforcing rib is fixedly connected between the limiting seat and the second mounting component, enabling the limiting seat to provide more stable limiting support for the sliding of the slide block. Attached Figure Description

[0032] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: first mounting component 1, insertion hole 101, second mounting component 2, first magnetic suction part 3, slide 4, mounting groove 401, actuating groove 402, second magnetic suction part 5, tension spring 6, first fixing pin 7, second fixing pin 8, rotating fork 9, rotating seat 10, rotating handle 11, limit seat 12, and reinforcing rib 13.

[0033] Example 1 This embodiment is as shown in the appendix. Figure 1 and Figure 4 As shown: A magnetic locking device for vehicles includes a first mounting member 1 and a second mounting member 2. The first mounting member 1 has an insertion hole 101 at one end facing the second mounting member 2. The insertion hole 101 is square in shape. A first magnetic suction part 3 is fixedly connected to the insertion hole 101 by screws. The top surface of the second mounting member 2 has a horizontally arranged sliding groove. A slide block 4 that is inserted into the insertion hole 101 is slidably connected in the sliding groove. That is, when the slide block 4 slides horizontally, the end of the slide block 4 can be inserted into the insertion hole 101, so that the first mounting member 1 and the second mounting member 2 are relatively fixed and the locking of the first mounting member 1 and the second mounting member 2 is achieved.

[0034] Combination Figure 1 and Figure 2 One end of the slide block 4, which can slide outside the second mounting member 2, is fixedly connected to a second magnetic attraction part 5 that magnetically engages with the first magnetic attraction part 3. The second mounting member 2 is connected to a drive structure that drives the slide block 4 to slide laterally, and an elastic element is fixedly connected between the second mounting member 2 and the slide block 4. When the first magnetic attraction part 3 and the second magnetic attraction part 5 are in a mutually facing magnetic attraction state, the second magnetic attraction part 5 and the slide block 4 slide into the insertion hole 101 of the second mounting base, so that the first mounting member 1 and the second mounting member 2 can remain locked. In this embodiment, to simplify the structure and facilitate control, the first magnetic attraction part 3 includes a permanent magnet, and the second magnetic attraction part 5 includes an electromagnet fixedly connected to the end of the slide block 4 by screws.

[0035] In this embodiment, a vertically penetrating mounting groove 401 is provided on the top surface of the slide block 4. The drive mechanism and the elastic element are both installed in the mounting groove 401, thereby making the overall structure more compact. The elastic element includes a tension spring 6 fixedly connected between the second mounting member 2 and the slide block 4. To facilitate the installation and use of the tension spring 6, in this embodiment, a first fixing nail 7 is fixedly connected to the second mounting member 2 by threaded connection or welding, and a second fixing nail 8 is fixedly connected to the slide block 4 by threaded connection or welding. One end of the tension spring 6 is hooked and fixed to the first fixing nail 7, and the other end is hooked and fixed to the second fixing nail 8.

[0036] Combination Figure 2 and Figure 3 In this embodiment, the driving mechanism includes a rotating component and a rotating fork 9 fixedly connected to the rotating component. The rotating component includes a rotating seat 10 rotatably connected to the second mounting component 2 via a bearing. The rotating fork 9 is integrally formed on the side wall of the rotating seat 10. The side wall of the slide 4 has a moving groove 402 communicating with the sliding groove. The rotating fork 9 is inserted into the moving groove 402 and is movably engaged with the moving groove 402. When the rotating fork 9 rotates with the rotating seat 10, the rotating fork 9 can drive the slide 4 to slide relative to the second mounting component 2 through the moving groove 402. Meanwhile, to facilitate the rotation of the rotating seat 10, a rotating handle 11 is integrally formed on the top of the rotating seat 10. During use, the rotating handle 11 can be manually rotated to drive the rotating seat 10 to rotate. To facilitate the operation of the rotating handle 11, it can be set as a butterfly shape or other shapes, and anti-slip parts such as anti-slip threads can be provided on the outer side of the rotating handle 11. Of course, in other embodiments besides this one, the rotating seat 10 can be driven by a pressing method or by an electric motor for automatic drive, which will not be described here. In addition, in this embodiment, since the rotating fork 9 is inserted into the actuation groove 402, the rotating fork 9 can limit the sliding seat 4 perpendicular to the sliding direction of the sliding seat 4 by relying on the insertion and cooperation between the rotating fork 9 and the actuation groove 402 (i.e., Figure 1 To prevent the slide block 4 from slipping off the slide groove during sliding, and to improve the stability of limiting the slide block 4, in this embodiment, a rotating fork 9 is provided on both the front and rear sides of the rotating seat 10. Correspondingly, there are two actuating grooves 402 on the slide block 4. In order to enable the rotating fork 9 to drive the slide block 4 to slide smoothly in the lateral direction, the actuating grooves 402 are offset along the lateral direction of the slide block 4. During use, only one rotating fork 9 plays the role of driving the slide block 4 to slide, and the other rotating fork 9 only plays the role of vertical limiting.

[0037] The specific implementation process is as follows: When the first mounting member 1 and the second mounting member 2 are in the locked state, the first magnetic attraction part 3 and the second magnetic attraction part 5 are facing each other and magnetically attracted to each other. At this time, the end of the slide 4 is inserted into the insertion hole 101, so that the first mounting member 1 and the second mounting member 2 cannot rotate relative to each other and are locked. When it is necessary to unlock the first mounting member 1 and the second mounting member 2, the rotating handle 11 drives the rotating seat 10 to rotate. When the rotating seat 10 rotates, it drives the rotating fork 9 to rotate synchronously. The rotating fork 9 drives the slide 4 to slide relative to the second mounting member 2, so that the end of the slide 4 is out of the insertion hole 101. At this time, the first mounting member 1 and the second mounting member 2 can be rotated relative to each other, thereby effectively unlocking the first mounting member 1 and the second mounting member 2. After the first mounting member 1 and the second mounting member 2 are unlocked, the slide 4 slides into the second mounting member 2 under the tension of the tension spring 6, avoiding the end of the slide 4 from protruding out of the second mounting member 2 and colliding with other parts.

[0038] When it is necessary to re-lock the first mounting part 1 and the second mounting part 2, simply rotate the first mounting part 1 and the second mounting part 2 relative to each other so that the slide 4 is rotated to face the socket 101. At this time, under the magnetic attraction of the first magnetic attraction part 3 and the second magnetic attraction part 5, the slide 4 and the second magnetic attraction part 5 slide towards the first magnetic attraction part 3, and the slide 4 is reinserted into the socket 101, thus successfully achieving a stable lock-on of the first mounting part 1 and the second mounting part 2.

[0039] Example 2 The difference between Embodiment 2 and Embodiment 1 is that in this embodiment, a limiting member that cooperates with the slide block 4 is fixedly connected to the second mounting member 2. When the first magnetic attraction part 3 and the second magnetic attraction part 5 move away from each other, the tension spring 6 pulls the slide block 4 to slide until it abuts against the limiting member, and the second magnetic attraction part 5 and the slide block 4 slide into the second mounting member 2. Specifically, as shown... Figure 5 As shown, the limiting component includes a limiting seat 12 fixedly connected to the second mounting component 2 by integral molding, welding, or screw fastening. A reinforcing rib 13 is fixedly connected between the side of the limiting seat 12 facing away from the second magnetic attraction part 5 and the second mounting component 2. The reinforcing rib 13 enhances the stability of the connection between the limiting plate and the second mounting component 2. In this embodiment, when the first mounting component 1 and the second mounting component 2 are unlocked and disengaged, the slide block 4 and the second magnetic attraction part 5 slide into the second mounting component 2 under the tension of the tension spring 6. The slide block 4 stops sliding into the second mounting component 2 when it abuts against the limiting plate. At this time, the entire slide block 4 is located within the groove of the second mounting component 2, and under the tension of the tension spring 6, the slide block 4 remains in abutting state against the limiting plate, preventing the slide block 4 from idly swaying laterally within the groove. This not only reduces abnormal noise but also prevents the end of the slide block 4 from sliding out of the groove and colliding with other components, causing damage.
