Description

Technical Field

[0001] This utility model belongs to the field of automotive key protection technology, specifically relating to an automotive key protective shell. Background Technology

[0002] With the rapid development of the automotive industry, cars have become an indispensable means of transportation in people's daily lives. As an important component for controlling key operations such as starting the car and opening and closing the doors, the safety, durability and ease of use of car keys have received increasing attention. In order to protect car keys from damage caused by the external environment, such as scratches, collisions and moisture, car key protective cases have emerged.

[0003] Existing car key protective cases also have some defects in the design of the snap-fit ​​mechanism. The snap-fit ​​mechanism of the protective case is not designed reasonably. During the snap-fit ​​process, the snap-fit ​​parts are prone to scratching and collision, which can lead to damage to the snap-fit ​​parts and affect the normal use of the protective case. For example, if the edge of the snap-fit ​​groove is too sharp, it may cause scratch damage to the elastic clip during the snap-fit ​​process, reducing the service life and snap-fit ​​performance of the elastic clip. Therefore, a new car key protective case is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a car key protective shell to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A car key protective case includes an outer shell frame, a mounting upper cover, and a mounting lower cover, and further includes:

[0007] A snap-fit ​​mechanism is used to snap-fit ​​and fix the upper mounting cover and the lower mounting cover. The snap-fit ​​mechanism is located on the upper mounting cover and the lower mounting cover. The snap-fit ​​mechanism includes a pull opening, an elastic clip, and a snap-fit ​​groove.

[0008] The upper and lower mounting covers are made of soft PVC and ABS, which can protect the car key while providing a suitable operating feel and can withstand a certain degree of external pressure and impact without being easily damaged. At the same time, they ensure good matching in terms of thermal expansion coefficient and hardness, which facilitates the stable operation of the snap-fit ​​mechanism and also contributes to the consistency and coordination of the overall appearance.

[0009] Preferably, the pull tab is formed on the upper cover, and the pull tab may be frosted to increase the friction between the user's fingers and the pull tab, making it easier for the user to operate the pull tab to assist in separating or installing the upper cover and the lower cover.

[0010] Preferably, the elastic clips are disposed on both sides of the outer wall of the mounting cover. The elastic clips are integrally formed with the mounting cover and have a certain elastic deformation capacity. They can undergo elastic deformation when subjected to external force, thereby cooperating with the corresponding snap-fit ​​structure to achieve the snap-fit ​​function. The material of the elastic clips is the same as that of the mounting cover, ensuring that they have physical properties that match the mounting cover.

[0011] Preferably, the snap-fit ​​grooves are formed on both sides of the mounting cover, corresponding to the positions of the elastic clips, providing a space for the elastic clips to snap into place; the edges of the snap-fit ​​grooves can be chamfered to avoid scratching or damaging the elastic clips during the snap-fit ​​process.

[0012] Preferably, the elastic clip and the snap-fit ​​groove are configured to snap into each other. During the installation of the upper cover and the lower cover, the elastic clip can snap into the snap-fit ​​groove to fix the two together. At the same time, the outer side wall of the upper cover and the inner side wall of the lower cover are configured to slide together. This sliding fit allows the upper cover and the lower cover to slide smoothly during installation and removal, and ensures a tight fit between the two after snapping, preventing loosening.

[0013] Preferably, the upper mounting cover is located above the outer shell frame, and the lower mounting cover is installed on the bottom of the inner wall of the outer shell frame, with the bottom of the lower mounting cover and the bottom of the outer shell frame at the same level. This structural design makes the overall appearance of the car key protective case flat, and at the same time makes it easy to place the car key inside the protective case for protection.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The lower mounting cover of this invention is made of ABS material, which protects the car key motherboard from external scratches, collisions, moisture, and other damage, while providing a comfortable operating feel for the user. The upper mounting cover is made of a combination of soft PVC and ABS material, which has a certain degree of flexibility and elasticity, and can withstand a certain degree of external pressure and impact without being easily damaged. It effectively protects the car key motherboard and provides a comfortable operating feel for the user. At the same time, the outer side wall of the upper mounting cover and the inner side wall of the lower mounting cover are designed to slide together, allowing the upper and lower mounting covers to slide smoothly during installation and removal, reducing resistance during installation and removal, and improving the convenience of user operation. Furthermore, the simple flat design of the upper and lower mounting covers provides users with more DIY options. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-3 As shown, a car key protective case includes an outer shell frame 1, a mounting upper cover 2 and a mounting lower cover 201, and also includes a snap-fit ​​mechanism for snapping and fixing the mounting upper cover 2 and the mounting lower cover 201. The snap-fit ​​mechanism is located on the mounting upper cover 2 and the mounting lower cover 201, and includes a pull opening 202, an elastic clip 203 and a snap-fit ​​groove 204.

[0022] The present invention is further described in detail. The materials of the upper cover 2 and the lower cover 201 include soft PVC and ABS, which can protect the car key while providing a suitable operating feel and can withstand a certain degree of external pressure and impact without being easily damaged. At the same time, it ensures that the two have good matching in terms of thermal expansion coefficient and hardness, which facilitates the stable operation of the snap-fit ​​mechanism and also contributes to the consistency and coordination of the overall appearance.

[0023] This utility model is further described in detail as follows: A pull tab 202 is formed on the upper mounting cover 2. The pull tab 202 can be surface-frosted to increase the friction between the user's fingers and the pull tab 202, facilitating the user's operation of the pull tab 202 to assist in separating or installing the upper mounting cover 2 and the lower mounting cover 201. Elastic clips 203 are provided on both sides of the outer wall of the upper mounting cover 2. The elastic clips 203 are integrally formed with the upper mounting cover 2 and have a certain elastic deformation capacity, capable of elastic deformation under external force, thereby cooperating with the corresponding snap-fit ​​structure to achieve the snap-fit ​​function. The material of the elastic clips 203 is the same as that of the upper mounting cover 2, ensuring that it has physical properties matching the upper mounting cover 2. Snap-fit ​​grooves 204 are formed on both sides of the lower mounting cover 201, corresponding to the positions of the elastic clips 203, providing a space for the elastic clips 203 to snap-fit. The edges of the snap-fit ​​grooves 204 can be chamfered. To avoid scratching or damaging the elastic clip 203 during the snap-fit ​​process, the elastic clip 203 and the snap-fit ​​groove 204 are designed for corresponding snap-fit. During the installation of the upper cover 2 and the lower cover 201, the elastic clip 203 can snap into the snap-fit ​​groove 204 to achieve a snap-fit ​​fixation between the two. At the same time, the outer side wall of the upper cover 2 and the inner side wall of the lower cover 201 are slidably fitted. This slidable fitting allows the upper cover 2 and the lower cover 201 to slide smoothly during installation and removal, and ensures a tight fit between the two after snap-fit, preventing loosening. The upper cover 2 is located on the top of the outer shell frame 1, and the lower cover 201 is installed on the bottom of the inner wall of the outer shell frame 1. The bottom of the lower cover 201 is at the same level as the bottom of the outer shell frame 1. This structural design makes the overall appearance of the car key protective case flat and facilitates the placement of the car key inside the protective case for protection.

[0024] As can be seen from the above, the pull tab 202 is provided on the upper cover 2, and the surface of the pull tab 202 is frosted. When the user needs to separate or install the upper cover 2 from the lower cover 201, the fingers can be easily inserted into the pull tab 202. Since the surface of the pull tab 202 is frosted, the friction between the fingers and the pull tab 202 is greatly increased. In this way, the user can apply force more easily when operating the pull tab 202, thereby assisting in the separation or installation of the upper cover 2 from the lower cover 201, avoiding the problem of fingers slipping and operation difficulties caused by the smoothness of the pull tab 202.

[0025] The elastic clips 203 are disposed on both sides of the outer wall of the mounting cover 2 and are integrally formed with the mounting cover 2. This integral forming design makes the connection between the elastic clips 203 and the mounting cover 2 firm and reliable, while simplifying the manufacturing process. The elastic clips 203 have a certain elastic deformation capacity. When the mounting cover 2 and the mounting lower cover 201 are installed, the elastic clips 203 will be squeezed by the inner side wall of the mounting lower cover 201, thus undergoing elastic deformation. At the same time, the snap-fit ​​grooves 204 are formed on both sides of the mounting lower cover 201, and are positioned with the elastic clips 203. Correspondingly, a snap-fit ​​space is provided for the elastic clip 203. As the upper cover 2 continues to move downward, the elastic clip 203 will gradually enter the snap-fit ​​groove 204. At this time, the elastic clip 203 returns to its original shape and forms a snap-fit ​​fixation with the snap-fit ​​groove 204, realizing the connection between the upper cover 2 and the lower cover 201. Moreover, the edge of the snap-fit ​​groove 204 is chamfered. This design avoids scratch damage between the elastic clip 203 and the edge of the snap-fit ​​groove 204 during the snap-fit ​​process, ensuring the integrity of the elastic clip 203 and the normal operation of the snap-fit ​​mechanism.

[0026] The outer wall of the upper cover 2 and the inner wall of the lower cover 201 are slidably fitted together. During installation and removal, this slidable fit allows the upper cover 2 and the lower cover 201 to slide smoothly together. When the user installs the upper cover 2 onto the lower cover 201, the upper cover 2 can move smoothly downwards along the inner wall of the lower cover 201, reducing resistance during installation and improving installation efficiency. Similarly, during removal, the user can easily remove the upper cover 2 from the lower cover 201. In addition, after snapping together, this slidable fit ensures a tight fit between the two, preventing loosening. Because the contact surfaces of the upper cover 2 and the lower cover 201 are tightly fitted, external dust, moisture, and other impurities are less likely to enter the protective shell, thus better protecting the car key.

[0027] The upper cover 2 is positioned above the outer shell frame 1, and the lower cover 201 is installed on the bottom of the inner wall of the outer shell frame 1. The bottom of the lower cover 201 is at the same level as the bottom of the outer shell frame 1. This structural design makes the overall appearance of the car key protective case flat and aesthetically pleasing. When the user places the car key with the protective case on a table or other flat surface, the protective case can be placed stably without shaking or tilting. At the same time, this structural design also makes it easy to place the car key inside the protective case for protection. When placing the car key, the user only needs to put the key into the lower cover 201 and then close the upper cover 2. The key is then fixed by the snap-fit ​​mechanism. The operation is simple and convenient.

[0028] Through the above technical solution, the upper cover 2 and lower cover 201 of this utility model are made of a combination of soft PVC and ABS materials. This choice brings many advantages. On the one hand, soft PVC and ABS can protect the car key from external scratches, collisions, moisture, and other damage, while providing users with a suitable operating feel. Compared with hard plastic materials, this soft material will not make users feel stiff or uncomfortable during use, but has a softer, skin-friendly touch, greatly improving the user experience. On the other hand, soft PVC and ABS materials have a certain degree of flexibility and elasticity, and can withstand a certain degree of external pressure and collision without being easily damaged. Compared with rubber materials, which are prone to aging, deformation, and may stick or become sticky, the materials selected in this utility model have a longer service life and can more effectively protect the car key. In addition, soft PVC and ABS materials have good matching in terms of thermal expansion coefficient and hardness, which ensures... The upper cover 2 and lower cover 201 maintain a stable fit under varying temperature conditions, preventing loosening or uneven gaps. This ensures stable operation of the locking mechanism and enhances the overall consistency and harmony of the car key protective case. The elastic clip 203 and the locking groove 204 are designed for corresponding locking. During installation, the elastic clip 203 smoothly engages with the locking groove 204, securing the two together. Furthermore, the outer wall of the upper cover 2 and the inner wall of the lower cover 201 are designed for sliding contact. This sliding contact allows for smooth sliding during installation and removal, reducing resistance and improving user convenience. After locking, this sliding contact ensures a tight fit, preventing loosening and ensuring the car key protective case stably protects the car key.

[0029] The pull tab 202 is formed on the upper cover 2, and the surface of the pull tab 202 is frosted. This design greatly increases the friction between the user's fingers and the pull tab 202, making it easier and more convenient for the user to operate the pull tab 202. It can smoothly assist in the separation or installation of the upper cover 2 and the lower cover 201. Compared with the smooth surface of the pull tab 202 design, the pull tab 202 design of this utility model avoids the problem of the user's fingers slipping during operation, and improves the user's efficiency and operating experience.

[0030] The elastic clips 203 are disposed on both sides of the outer wall of the mounting cover 2 and are integrally formed with the mounting cover 2. This integral forming design not only simplifies the production process and reduces production costs, but also ensures the connection strength and stability between the elastic clips 203 and the mounting cover 2. The elastic clips 203 have a certain elastic deformation capacity and can undergo elastic deformation when subjected to external force, thereby cooperating with the corresponding snap-fit ​​structure to achieve the snap-fit ​​function. At the same time, the material of the elastic clips 203 is the same as that of the mounting cover 2, which makes the elastic clips 203 have physical properties that match those of the mounting cover 2, such as elastic modulus and hardness, further ensuring the stability and reliability of the snap-fit ​​mechanism.

[0031] The snap-fit ​​grooves 204 are provided on both sides of the mounting cover 201, corresponding to the positions of the elastic snap-fit ​​members 203, providing a space for the elastic snap-fit ​​members 203 to snap into place. Furthermore, the edges of the snap-fit ​​grooves 204 are chamfered. This detail design avoids scratch damage between the elastic snap-fit ​​members 203 and the edges of the snap-fit ​​grooves 204 during the snap-fit ​​process, extending the service life of the elastic snap-fit ​​members 203 and ensuring the normal operation of the snap-fit ​​mechanism.

[0032] The upper cover 2 is positioned above the outer shell frame 1, and the lower cover 201 is installed on the bottom of the inner wall of the outer shell frame 1. The bottom of the lower cover 201 is at the same level as the bottom of the outer shell frame 1. This structural design makes the overall appearance of the car key protective case flat and aesthetically pleasing. At the same time, this structural design also makes it easier to place the car key inside the protective case for protection. Users can more conveniently put and take out the car key into the protective case, improving the convenience of use.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
