[0002] The existing automobile seat is usually provided with a movable door at the back plate of the front seat, and the rear of the movable door has a containing space for containing a display screen and other devices.

[0003] The existing movable door is generally designed as a sliding structure to open or close the containing space, and the display screen inside the containing space can be removed after the containing space is opened.

[0004] The existing movable door and its corresponding structure design occupy a large space and are not suitable for use on a compact car. UTILITY MODEL CONTENTS

[0005] In view of the deficiencies and defects of the prior art, a seat back plate magnetic attraction type switch with compact structure and convenient use is provided.

[0006] A seat back plate magnetic attraction type switch comprises:

[0007] A movable panel is movably arranged on a support in front and back directions.

[0008] A magnetic control rotating assembly is arranged on the movable panel and can independently rotate along an axis A in a circumferential direction relative to the movable panel.

[0009] A locking pin and a stop portion arranged on the support, the locking pin is movably arranged on the movable panel and can be moved to form a locking cooperation with the stop portion on the support to lock the movable panel.

[0010] The magnetic control rotating assembly and the locking pin are in transmission cooperation, at the front part of the movable panel, the magnetic member exerts a magnetic action on the magnetic control rotating assembly to make the magnetic control rotating assembly rotate along the axis A in the circumferential direction, and the magnetic control rotating assembly drives the locking pin to move to be out of the locking cooperation with the stop portion to make the movable panel movable.

[0011] Compared with the prior art, the seat back plate magnetic attraction type switch has the following advantages:

[0012] In the scheme, if it is needed to make the movable panel open the opening on the support:

[0013] By placing the magnetic component at the front of the panel and applying a magnetic force (e.g., magnetic attraction or repulsion) to the magnetically controlled rotating assembly, the magnetically controlled rotating assembly can rotate circumferentially along axis A. During the movement of the magnetically controlled rotating assembly, the locking pin moves until it disengages from the locking part, after which the movable door panel can be operated to open the opening on the bracket.

[0014] Compared to traditional unlocking mechanisms that rely on sliding magnets, this device offers the following advantages:

[0015] 1. It features high compactness, which facilitates device miniaturization, as well as simple structure and reliable operation;

[0016] 2. Magnetic drive is relatively stable, reducing wear and failure probability caused by frequent mechanical operation, and improving the reliability and service life of the switch to a certain extent.

[0017] 3. Unlocking is achieved by using magnets on the front of the active panel, which facilitates a hidden switch design, making the seat look more concise and beautiful, while also reducing the chance of accidental unlocking.

[0018] As an improvement of this utility model, the magnetically controlled rotating assembly is provided with a cam drive surface, the locking pin is movably arranged up and down, and the locking pin is provided with a transmission part, which is located below the cam drive surface. When the magnetically controlled rotating assembly rotates, the cam drive surface with an increased diameter cooperates with the transmission part to make the locking pin move downward, thereby driving the locking pin to move until it disengages from the stop part.

[0019] As an improvement to this utility model

[0020] The locking pin abuts against an elastic element, which is a component capable of generating elastic deformation and providing elastic force. When the locking pin moves downward, the elastic element undergoes elastic deformation and is pre-tightened. After being pre-tightened, the elastic element provides a pre-tightening force that causes the locking pin to have an upward tendency. After the movable panel is reset, the pre-tightening force drives the locking pin to move upward and locks it with the stop part.

[0021] As an improvement to this utility model

[0022] The magnetically controlled rotating assembly includes a rotating base and a magnet disposed on the rotating base, and the cam driving surface is disposed on the rotating base;

[0023] The rotating seat is rotatably connected to the rear of the movable panel via a rotating connection structure, which enables the rotating seat to rotate circumferentially relative to the movable panel about axis A.

[0024] The bottom of the movable panel is hinged to the bracket, and the hinge structure allows the movable panel to rotate relative to the bracket.

[0025] As an improvement of this utility model, the stop part is a vertical plane, and the upper rear wall of the locking pin is also a plane, and this plane is adapted to the plane of the stop part. When locking, the two planes fit tightly together to achieve locking.

[0026] As an improvement to this utility model

[0027] The upper front part of the locking pin is provided with a guide surface that gradually slopes forward from top to bottom. The guide surface is a smooth inclined surface used to guide the movement of the locking pin.

[0028] The bracket is provided with a clearance groove. The bottom wall of the clearance groove is adapted to the structure of the guide surface. During the forward rotation of the movable panel, the guide surface contacts the bottom wall of the clearance groove. The bottom wall of the clearance groove applies a force to the guide surface. This force causes the locking pin to move downward so that the upper end of the locking pin avoids the bracket.

[0029] As an improvement to this utility model

[0030] A torsion spring is provided between the movable panel and the bracket. The torsion spring is a spring component with torsional elasticity. When the rotating seat rotates backward, the torsion spring undergoes torsional deformation and is pre-tightened. The elastic torque generated after the torsion spring is pre-tightened drives the movable panel to always have the tendency to rotate forward and reset. Attached Figure Description

Detailed Implementation

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] Please see Figures 1-7 As shown, a magnetic switch for a seat back panel includes:

[0041] Movable panel 1, which is movably mounted on bracket 2;

[0042] A magnetically controlled rotating assembly 3 is disposed on the movable panel 1, and the magnetically controlled rotating assembly 3 can rotate independently along axis A relative to the movable panel 1.

[0043] Locking pin 4 and stop part 5 provided on bracket 2. The locking pin 4 is movably provided on movable panel 1 and can be moved to form a locking engagement with stop part 5 on bracket 2 to lock movable panel 1.

[0044] The magnetically controlled rotating assembly 3 is driven by the locking pin 4. At the front of the movable panel 1, the magnetic component 6 applies a magnetic effect to the magnetically controlled rotating assembly 3, causing the magnetically controlled rotating assembly 3 to rotate circumferentially along axis A. The magnetically controlled rotating assembly 3 drives the locking pin 4 to move until it disengages from the locking engagement with the stop part 5, so that the movable panel 1 can move.

[0045] In this solution, if it is necessary for the movable panel 1 to open the opening on the bracket 2:

[0046] Place the magnetic component 6 at the front of the panel to apply a magnetic force (e.g., magnetic attraction or magnetic repulsion) to the magnetically controlled rotating assembly 3.

[0047] The magnetically controlled rotating component 3 can rotate circumferentially along axis A. During the movement of the magnetically controlled rotating component 3, the locking pin 4 is moved until it disengages from the locking engagement with the stop part 5. Then the movable door panel can be operated to move it to open the opening on the bracket 2.

[0048] Compared to traditional unlocking mechanisms that rely on sliding magnets, this device offers the following advantages:

[0049] 1. It features high compactness, which facilitates device miniaturization, as well as simple structure and reliable operation;

[0050] 2. Magnetic drive is relatively stable, reducing wear and failure probability caused by frequent mechanical operation, and improving the reliability and service life of the switch to a certain extent.

[0051] 3. Unlocking is achieved by using magnetism at the front of the active panel 1, which facilitates a hidden switch design, making the seat look more concise and beautiful, while also reducing the chance of accidental unlocking.

[0052] As an improvement of this utility model, the magnetically controlled rotating assembly 3 is provided with a cam drive surface 7, the locking pin 4 is movably arranged up and down, and the locking pin 4 is provided with a transmission part 8. The transmission part 8 is located below the cam drive surface 7. When the magnetically controlled rotating assembly 3 rotates, the cam drive surface 7 with an increased diameter cooperates with the transmission part 8 to make the locking pin 4 move downward, thereby driving the locking pin 4 to move until it disengages from the stop part 5.

[0053] Specifically: the cam drive surface 7 is set on the rotating seat 10 and is arranged parallel to the axis A;

[0054] The transmission part 8 is a triangular structure that protrudes upwards.

[0055] When the active panel 1 is in the initial (closed) position, the locking pin 4 and the stop part 5 are in a locked engagement state, the rotating seat 10 is in an inclined position after reverse rotation, and the area where the cam drive surface 7 is closer to the axis A abuts against the upper apex of the transmission part 8.

[0056] Furthermore, the magnetic component 6 is placed in front of the panel, facing the magnet 11 and parallel to the position where the magnet 11 drives the rotating seat 10 to rotate, causing the locking pin 4 to move downward.

[0057] At this time, the magnetic force can drive the rotating seat 10 to rotate in the positive direction. The area where the cam drive surface 7 is far from the axis A gradually abuts against the upper apex of the transmission part 8, thereby driving the locking pin 4 to move downward.

[0058] As the rotating seat 10 rotates in the opposite direction, the area where the cam drive surface 7 is closer to the axis A gradually comes into contact with the upper apex of the transmission part 8, and the locking pin 4 moves upward under the action of the elastic element 9.

[0059] By utilizing the characteristics of the cam mechanism, a more precise and stable transmission is achieved. Compared to some simple direct connection methods, the cam drive surface 7 can gradually and stably push the locking pin 4 to move according to the change of rotation angle, ensuring the smoothness of the unlocking action, reducing the risk of jamming, and improving the reliability of the entire switching system.

[0060] As an improvement to this utility model

[0061] The locking pin 4 abuts against the elastic element 9, which is a component capable of generating elastic deformation and providing elastic force. When the locking pin 4 moves downward, the elastic element 9 undergoes elastic deformation and is pre-tightened. After being pre-tightened, the elastic element 9 provides a pre-tightening force that causes the locking pin 4 to have an upward tendency. After the movable panel 1 is reset, the pre-tightening force drives the locking pin 4 to move upward and locks it with the stop part 5.

[0062] The design of the elastic element enables an automatic locking function, eliminating the need for additional manual operation to complete the locking action and improving ease of use. Simultaneously, the preload of the elastic element 9 can compensate for gap changes caused by component wear and other factors, maintaining a consistently good locking effect and extending the switch's lifespan.

[0063] As an improvement to this utility model

[0064] The magnetically controlled rotating assembly 3 includes a rotating base 10 and a magnet 11 disposed on the rotating base 10, and the cam driving surface 7 is disposed on the rotating base 10;

[0065] The rotating seat 10 is rotatably connected to the rear of the movable panel 1 via a rotating connection structure 12, which enables the rotating seat 10 to rotate circumferentially relative to the movable panel 1 about axis A.

[0066] The bottom of the movable panel 1 is hinged to the support 2, and the hinge structure 13 allows the movable panel 1 to rotate relative to the support 2.

[0067] This structural design makes the installation and movement of the magnetically controlled rotating assembly 3 more stable, and the rotating connection structure 12 can ensure that the rotating seat 10 rotates smoothly around the axis A, reducing unnecessary shaking and friction.

[0068] Meanwhile, the hinged connection between the bottom of the movable panel 1 and the bracket 2 means that rotating the movable panel 1 backward opens the receiving space, while rotating it forward closes the receiving space.

[0069] This ensures reliable device operation and a better user experience.

[0070] As an improvement of this utility model, the stop part 5 is a vertical plane, and the upper rear wall of the locking pin 4 is also a plane, and this plane is adapted to the plane of the stop part 5. When locking, the two planes fit tightly together to achieve locking.

[0071] The close contact between the planes increases the contact area during locking, thereby improving the stability and reliability of the locking mechanism. Compared to some point or line contact locking methods, planar contact can better withstand external forces and prevent the movable panel 1 from rotating accidentally.

[0072] As an improvement to this utility model

[0073] The upper front part of the locking pin 4 is provided with a guide surface 14 that gradually slopes forward from top to bottom. The guide surface 14 is a smooth inclined surface used to guide the movement of the locking pin 4.

[0074] The bracket 2 is provided with a clearance groove 15. The bottom wall of the clearance groove 15 is adapted to the structure of the guide surface 14. During the forward rotation of the movable panel 1, the guide surface 14 contacts the bottom wall of the clearance groove 15. The bottom wall of the clearance groove 15 applies a force to the guide surface 14. This force causes the locking pin 4 to move downward so that the upper end of the locking pin 4 avoids the bracket 2.

[0075] The design of the guide surface 14 and the clearance groove 15 cleverly solves the problem of possible interference between the locking pin 4 and the bracket 2 during the rotation of the movable panel 1. When the movable panel 1 rotates, the locking pin 4 is automatically guided downward by the cooperation between the guide surface 14 and the bottom wall of the clearance groove 15, ensuring smooth and unobstructed rotation of the movable panel 1, while also reducing collisions and wear between components and improving the durability of the entire mechanism.

[0076] As an improvement to this utility model

[0077] A torsion spring 16 is provided between the movable panel 1 and the bracket 2. The torsion spring 16 is a spring component with torsional elasticity. When the rotating seat 10 rotates backward, the torsion spring 16 undergoes torsional deformation and is pre-tightened. The elastic torque generated after the torsion spring 16 is pre-tightened drives the movable panel 1 to always have the tendency to rotate forward and reset.

[0078] The torsion spring 16 enables the movable panel 1 to automatically reset, eliminating the need for manual reset after operation and improving the user experience. Furthermore, the elastic torque of the torsion spring 16 can buffer the rotation speed of the movable panel 1 to some extent, preventing excessive impact from rapid rotation, protecting related components, and extending the service life of the mechanism.

[0079] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
