Abstract
Description
Technical Field
[0001] The utility model belongs to the field of unlocking switch component execution, and particularly relates to a switch structure. Background Technique
[0002] With the continuous improvement of living standards, while people's demands for automotive performance, handling, and convenience and comfort performance are increasing, their requirements for the interior and exterior environment of automobiles are also constantly rising. Products such as automotive folding tables, armrests, and cup holders have moved from the original configuration of commercial vehicles to the ranks of mass-market vehicles. These products all require unlocking mechanisms during use. However, in traditional switch locking, the lock pins are exposed, and they can only perform linear reciprocating motion for locking and need to be arranged outside the product structure.
[0003] This form of unlocking switch obviously cannot meet people's needs. Especially when the product space is very small and no structural arrangement can be made outside, and when the movement is rotational, there are relatively serious collisions when using a linear switch, and a larger space is required to strengthen the switch.
[0004] In view of the above situation, there is a need to design a switch structure at present to meet people's in-depth understanding of the field of automotive interior unlocking mechanisms. Content of the Utility Model
[0005] The switch structure provided by the utility model is compact in structure, convenient to operate, has small space requirements, has hidden locking, and has a stable locking effect.
[0006] The technical solution provided by the utility model is as follows:
[0007] A switch structure, comprising:
[0008] A switch bracket, which is provided with two hinge holes of different sizes and three threaded holes;
[0009] An unlocking lever, with a locking barb at its front end, an unlocking pressure plate at its rear end, and a lever rotating shaft in the middle connected to the small hinge opening of the switch bracket;
[0010] A lock catch, with a rotating shaft structure at its middle position, a protruding limiting block structure on the shaft connected to the large hinge opening of the switch bracket, a connecting structure on the right side of the shaft, and the left side connected to the unlocking lever;
[0011] Two springs, one end of which is connected to the unlocking lever and the other end is connected to the lock catch.
[0012] Preferably, the large hinge hole of the switch bracket is connected to the lock catch by a fan-shaped waist-shaped hole, which plays a role in limiting the rotating shaft of the lock catch part, and the structure is more firm.
[0013] Preferably, a square positioning structure is arranged below the switch bracket for strengthening fixation and suppressing the deformation of the bracket.
[0014] Preferably, bump blocks are arranged on both the left and right sides below the middle shaft hole of the switch bracket. In the unlocked state, the spring is located above the bump blocks, and in the locked state, the spring is located below the bump blocks to maintain the position of the spring.
[0015] Preferably, the unlocking pressure plate at the rear end of the unlocking lever is an elongated type with a larger pressing area to ensure sensitive unlocking. Since the pressing area is large, when unlocking, pressing in the middle or on both sides can achieve the unlocking effect.
[0016] Preferably, a U-shaped long hole structure is arranged on the upper left side of the shaft of the lock catch for limiting; a V-shaped structure is arranged at the lower left of the shaft and connected to the unlocking lever.
[0017] Preferably, the spring is a tension spring, and there is always a tendency of a tension force.
[0018] The beneficial effects of the present utility model are as follows: A switch structure provided by the present utility model has a compact structure, convenient operation, small space requirements, hidden locking, and stable locking effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figures 2-5 It is a schematic diagram of the disassembled structure of a switch structure described in the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The following further describes the present utility model in detail with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.
[0022] As Figure 1 shown, the present utility model provides a switch structure, which includes: a switch bracket 110, which is provided with two hinge holes of different sizes and three threaded holes. A square positioning structure is arranged below the switch bracket to fix and improve rigidity. An unlocking lever 120, with a locking barb at its front end, an unlocking pressure plate at its rear end, and a lever rotating shaft in the middle connected to the small hinge port of the switch bracket 110; a lock catch 140, with a rotating shaft structure in the middle position, a protruding limiting structure on the shaft connected to the large hinge port of the switch bracket 110. The large hinge hole is connected to the lock catch by a fan-shaped waist-shaped hole. A connecting structure is arranged on the right side of the shaft, and the left side is connected to the unlocking lever 120; two springs 130, one end of which is connected to the unlocking lever 120 and the other end is connected to the lock catch. Bump blocks are arranged on both the left and right sides below the middle shaft hole of the switch bracket 110, and the springs 130 are in contact with the bump blocks to maintain the position of the springs 130.
[0023] The utility model realizes self-locking through the adoption of a modeling design clamping structure, continuously provides a pre-tightening force through a spring 130, and designs an unlocking mechanism according to the principle of the lever structure. Press the unlocking end of the unlocking lever 120, and through the lever rotating shaft, the clamping end is disengaged to unlock. The utility model provides a switch structure, which is applicable to products such as armrests, cup holders, and table boards, especially applicable to small-structured products with a compact space such as cup holders. It solves the problems of large unlocking space requirements for current products and the unlocking form being only applicable to linear motion unlocking.
[0024] As Figure 2 shown, the switch bracket 110 is provided with one main positioning and two auxiliary positionings, and at the same time is provided with threaded holes and can be screwed with the mating environmental part. On the left and right sides below the middle shaft hole, bump block structures are respectively arranged, which are used for spring limit, restricting the unlocking and locking positions of the spring 130 in two states. In the unlocking state, the spring is located above the bump block, and in the locking state, the spring is located below the bump block. The large hinge interface adopts a fan-shaped waist-shaped hole, which has a limiting effect on the rotating shaft of the lock catch 140, so as to improve the durability and stability of the structure. A square positioning structure is arranged below the whole, which is matched with the environmental part to fix the whole switch bracket 110 and achieve a high-rigidity effect.
[0025] As Figure 3 shown, the unlocking lever 120 is provided with a lever rotating shaft in the middle, which is matched with the small hole of the switch bracket to ensure normal rotation. A locking barb is arranged at the front section and connected with the spring 130. An extended unlocking pressing plate is arranged at the rear section, and symmetric unlocking planes are arranged at the unlocking end to make the unlocking effect more stable and accurate, ensuring sensitive unlocking and a large pressing area. Therefore, when unlocking, pressing in the middle or on both sides can achieve the unlocking effect.
[0026] As Figure 4 shown, one end of the spring 130 is connected with the unlocking lever 120, and the other end is connected with the lock catch 140. The spring 130 is a tension spring and always has a tendency of a tension acting force. It is symmetrically arranged on the bump blocks on the left and right sides below the middle shaft hole of the switch bracket 110.
[0027] As Figure 5 shown, the lock catch 140 is provided with a rotating shaft structure in the middle position, and a protruding limiting structure is arranged on the shaft, which has a limiting effect in cooperation with the waist-shaped hole of the switch bracket. The right side of the shaft is connected with the spring 130, a U-shaped long hole structure is arranged at the lower left side of the shaft, which is a limiting lock hole, and a V-shaped structure at the upper left of the shaft is connected with the unlocking lever 120. A spring connection lug is arranged at the rear end for spring connection.
[0028] As Figures 1-5As shown in the figure, when the opponent's locking rod moves to the position of the U-shaped locking opening of the lock catch 140, at this time, the locking rod abuts against the upper long plane of the U-shaped opening and continues to move, causing the lock catch 140 to rotate until the area is horizontal. At this time, the lower small plane of the U-shaped locking opening of the lock catch 140 abuts against the locking rod. At the same time, the V-shaped structure of the lock catch 140 cooperates with the unlocking lever 120 to form a self-locking during the stroke. Meanwhile, the tension of the spring 130 is tightened. Through the convex block on the switch bracket 110, it moves to the locking position, causing the V-shaped self-locking structure to receive the tension and automatically pre-tighten, always maintaining the locked state. Thus, the opponent's locking rod is restricted from opening through the U-shaped locking hole, achieving the locking purpose. At this time, press the unlocking pressing plate of the unlocking lever 120. Through the rotation of the lever shaft, the front V-shaped self-locking structure of the lock catch 140 is released. At the same time, the spring 130 is driven to move towards the unlocking position. Through the spring tension, the lock catch 140 rotates along the axis, and the opponent's locking rod is released from the U-shaped limiting structure, achieving the unlocking purpose.
[0029] The present utility model adopts the principle of tensioning with the spring 130 and structural limitation to achieve the self-locking of the force on the lock catch and the structure of the unlocking lever 120. Through the long-strip lock structure of the lock catch member, it cooperates with the opponent member for hook-type locking. By pressing the button cap at the unlocking end of the unlocking lever 120 to receive force, overcoming the acting force of the spring 130, through the lever principle, the self-locking structure between the unlocking lever 120 and the lock catch member is disengaged, achieving the unlocking effect.
[0030] Although the embodiments of the present utility model have been disclosed as above, it is not limited to only the applications listed in the description and embodiments. It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present utility model is not limited to specific details and the illustrated and described examples here.
