Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a car key that facilitates battery replacement. Background Technology

[0002] Currently, as an essential tool for vehicle use, the ease of battery replacement and structural stability of car keys are of great concern. Replacing the battery in traditional car keys typically requires the use of screwdrivers and other tools to remove screws, a cumbersome process that can easily damage the casing. Some tool-free keys suffer from loosely secured covers that are prone to loosening or even falling off during daily use, affecting aesthetics and potentially causing poor battery contact and key malfunction. Furthermore, some keys lack emergency use functionality, rendering the car door unusable when the battery is dead, causing significant inconvenience to users. Therefore, developing a car key with a simple structure, easy battery replacement, secure mounting, and emergency function is crucial for improving user experience and meeting market demands.

[0003] While existing technologies can achieve a certain degree of battery replacement, they suffer from drawbacks such as a lack of convenient disassembly and assembly structures and insecure fixation. In view of this, we propose a car key that facilitates battery replacement and solves the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a car key that facilitates battery replacement.

[0005] The technical solution of this utility model is as follows: A car key that facilitates battery replacement includes a housing and a cover. The housing has a cover on one side and a guide groove on the other side. The cover has a limiting plate on one side. The cover is inserted into the guide groove and connected to the housing through the limiting plate. The outer wall of the other side of the cover has a slot. The upper end of the housing has an insertion block. The insertion block is located in the slot. The limiting plate can move within the guide groove. After the cover is installed into the housing through the guide groove, it is fixed in the slot by the insertion block.

[0006] When using the car key with convenient battery replacement provided in this solution, first align the limiting plate on the cover with the guide groove on the housing and insert it. When the slot and the insert block overlap, the insert block automatically falls into the slot under the pushing force of the first and second springs, thus fixing the cover. When the battery needs to be replaced, pull the moving plate downwards with your finger. The moving plate moves and pulls the elastic band, which pulls the insert block away from the slot, releasing the fixation of the cover. Then push the cover out of the guide groove of the housing and place the battery into the mounting slot. The positive and negative terminals of the battery contact the first and second contacts, respectively. Repeat the above cover installation process to complete the battery replacement.

[0007] Preferably, the upper end of the housing is provided with two symmetrical grooves, and a first spring is fixedly connected to the inner wall of one end of the groove. The two sides of the insertion block are located in the groove, and the outer wall of one side of the insertion block is fixedly connected to one end of the first spring. The first spring provides a pushing force to the insertion block, so that the insertion block automatically falls into the slot.

[0008] Preferably, one side of the outer wall of the insert block is fixedly connected to one end of the elastic band, and the other end of the elastic band is fixedly connected to the upper outer wall of the movable plate. One side of the outer wall of the movable plate is provided with anti-slip texture, and the elastic band has good bending deformation ability to transfer the tension of the movable plate to the insert block.

[0009] Preferably, the lower outer wall of the movable plate is fixedly connected to two second springs, and the other end of the second spring is fixedly connected to the outer wall of the housing. The second springs provide a restoring force for the movable plate after the tension is released.

[0010] Preferably, a protrusion is fixedly connected to the upper outer wall of the housing. The protrusion is located below the elastic band, and the surface of the protrusion is rounded to reduce the wear and tear when the elastic band rubs against the housing.

[0011] Preferably, a mounting groove is provided on one side of the housing, and a first contact and a second contact are provided in the mounting groove. The mounting groove is used for battery installation, and the first contact and the second contact correspond to the positive and negative electrodes, respectively.

[0012] Preferably, the upper end of the housing is provided with a hanging ring, and the housing is provided with an electronic button and a mechanical button. The mechanical button is fixedly connected to the mechanical key by a torsion spring. Pressing the mechanical button can make the mechanical key pop out for emergency use in case of power failure or other situations.

[0013] Preferably, the outer wall of one side of the lid is provided with anti-slip texture, which can increase the friction between the fingers and the lid.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, through the linkage design of a movable plate, elastic band, and insert block, combined with the sliding structure of guide groove and limiting plate, enables rapid battery replacement. When the battery needs to be replaced, the user only needs to pull down the movable plate, which will cause the insert block to disengage from the slot via the elastic band, making it easy to remove the cover. During installation, the limiting plate of the cover is aligned with the guide groove and inserted. The insert block automatically snaps into the slot under the push of the first spring. No tools are required, making the operation simple and convenient, and greatly improving the efficiency of battery replacement for users.

[0016] II. Based on the first beneficial effect, this utility model ensures the stable fixation of the cover and the shell through a double spring structure. The first spring provides a continuous pushing force to the insert, making it firmly embedded in the slot and preventing the cover from accidentally falling off; the second spring assists the insert in accurately returning to its position when the moving plate resets, enhancing the reliability of the locking. At the same time, the tight cooperation between the limiting plate and the guide groove further restricts the movement of the cover. Combined with the engagement of the insert and the slot, a multi-dimensional stable connection is formed. Even under frequent use of the car key or impact from external forces, the connection stability between the cover and the shell can be guaranteed, ensuring the safety and normal use of the internal battery.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] Please see Figures 1-3 As shown, this embodiment is a car key that facilitates battery replacement, including a housing 4 and a cover 7. The cover 7 is provided on one side of the housing 4, and a guide groove 12 is provided on one side of the housing 4. A limiting plate 13 is provided on one side of the cover 7. The cover 7 is inserted into the guide groove 12 through the limiting plate 13 and connected to the housing 4. A slot 1 is provided on the outer wall of the other side of the cover 7. An insert 20 is provided at the upper end of the housing 4 and is located in the slot 1. In use, the cover 7 and the housing 4 are quickly connected by the sliding engagement of the limiting plate 13 in the guide groove 12. When the slot 1 and the insert 20 are aligned, the insert 20 automatically engages with the slot 1 under the action of a spring, forming a stable connection, ensuring that the cover 7 will not fall off accidentally, and also facilitating subsequent battery replacement.

[0029] Example 2

[0030] Please see Figures 1-3 As shown, this embodiment, based on embodiment 1, further includes: two grooves 15 on the upper end of the housing 4; a first spring 14 is fixedly connected to the inner wall of one end of each groove 15; two sides of the insert block 20 are disposed in the grooves 15; one outer wall of the insert block 20 is fixedly connected to one end of the first spring 14. In use, when the cover 7 is inserted into place along the guide groove 12, the elastic force of the first spring 14 pushes the insert block 20 towards the slot 1, making it tightly embedded in the slot 1, providing a reliable locking force. When it is necessary to remove the cover 7, external force overcomes the elastic force of the first spring 14, pulling the insert block 20 out of the slot 1, thus achieving the unlocking process.

[0031] One side of the outer wall of the insert 20 is fixedly connected to one end of the elastic band 19, and the other end of the elastic band 19 is fixedly connected to the upper outer wall of the movable plate 16. One side of the outer wall of the movable plate 16 is provided with anti-slip texture 8. When in use, the movable plate 16 is pressed and slid by the fingers, and the anti-slip texture 8 is used to increase the friction, making it easy to operate. The movement of the movable plate 16 is transmitted to the insert 20 through the elastic band 19, so as to control the position of the insert 20. The elastic band 19 has a certain degree of flexibility and can adapt to the relative position changes between the movable plate 16 and the insert 20, ensuring the effective transmission of force.

[0032] The lower outer wall of the movable plate 16 is fixedly connected to two second springs 17, and the other end of the second spring 17 is fixedly connected to the outer wall of the housing 4. In use, when an external force causes the movable plate 16 to move downward, the second spring 17 is compressed and stores elastic potential energy. When the external force disappears, the second spring 17 releases the elastic potential energy and pushes the movable plate 16 to return to its original position. At the same time, the elastic band 19 drives the insertion block 20 to return to its original position, ensuring that the insertion block 20 can be accurately inserted into the slot 1 to achieve the automatic locking function.

[0033] A protrusion 18 is fixedly connected to the upper outer wall of the housing 4. The protrusion 18 is located below the elastic band 19. During use, the protrusion 18 serves as a support point for the elastic band 19, changing the direction of force on the elastic band 19 and making it more stable during force transmission. At the same time, the surface of the protrusion 18 is rounded, which reduces friction with the elastic band 19, extends the service life of the elastic band 19, and ensures smooth operation.

[0034] The housing 4 has a mounting groove 10 on one side, and a first contact 9 and a second contact 11 are provided in the mounting groove 10. In use, the mounting groove 10 provides a stable installation position for the battery, ensuring that the battery will not move inside the car key. The first contact 9 and the second contact 11 correspond to the positive and negative terminals of the battery, respectively, to realize the connection of the circuit. After the battery is installed in place, the cover 7 fixes the contacts to ensure tight contact with the battery, ensuring the normal operation of the car key.

[0035] The upper end of the housing 4 is provided with a hanging ring 2. The housing 4 is provided with an electronic button 3 and a mechanical button 5. The mechanical button 5 is fixedly connected to the mechanical key 6 through a torsion spring. When in use, the hanging ring 2 makes it convenient for users to carry the car key and can be hung on a key chain or other items. The electronic button 3 is used to control the remote functions of the car, such as unlocking and locking. When the electronic part malfunctions or the battery is dead, pressing the mechanical button 5 will cause the mechanical key 6 to pop out, which can be used to manually open the car door, providing an emergency use function.

[0036] The outer wall of one side of the cover 7 is provided with anti-slip texture 8. When using the cover 7, when it is necessary to remove or install the cover, the fingers come into contact with the anti-slip texture 8, which increases the friction, making the operation easier and more stable, avoiding slippage during operation, and improving the user experience.

[0037] Instructions for use: When using this device, first align the limiting plate 13 on the cover 7 with the guide groove 12 on the housing 4 and insert it. When the slot 1 and the insert 20 overlap, the insert 20 will automatically fall into the slot 1 under the pushing force of the first spring 14 and the second spring 17, thus fixing the cover 7. When the battery needs to be replaced, pull the moving plate 16 down with your finger. The moving plate 16 moves and pulls the elastic band 19. The elastic band 19 pulls the insert 20 away from the slot 1, releasing the fixation of the cover 7. Then push the cover 7 out of the guide groove 12 of the housing 4 and place the battery into the mounting slot 10. The positive and negative terminals of the battery will contact the first contact 9 and the second contact 11, respectively. Repeat the above installation process of the cover 7 to complete the battery replacement.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
