Technical Field
[0001] This application relates to the field of vehicle technology, specifically to a vehicle key structure. Background Technology
[0002] As vehicles become increasingly intelligent, smart keys are now a common feature, gradually replacing traditional mechanical keys.
[0003] In related technologies, a vehicle electronic smart key structure applied in the field of vehicle component technology is disclosed. This key structure connects the sliding cover and the rear cover by setting a limiting groove and a limiting block between them, and the limiting groove and the limiting block engage. When it is necessary to remove the sliding cover to replace the battery, simply push the sliding cover.
[0004] However, its sliding cover and back cover have a complex structure, and wear increases with repeated use, which may cause the limiting groove and limiting block to fail to engage. Utility Model Content
[0005] The purpose of this application is to provide a vehicle key structure that solves the problem of the complexity of existing vehicle key structures.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] This application provides a vehicle key structure including a first housing, a second housing, an inner cover, a decorative ring, a push rod, and an elastic element. The inner cover is located between the first housing and the second housing. The push rod is disposed between the second housing and the inner cover. A first locking tooth is provided on the side of the push rod near the second housing, and a second locking tooth is provided on the side of the second housing near the push rod; the first and second locking teeth engage. The elastic element is arranged along the axial direction of the push rod, with one end connected to the push rod and the other end connected to the inner cover. The decorative ring is arranged along the outer periphery of the first and second housings and engages with the inner cover.
[0008] According to the above-mentioned technical means, the push rod is pushed along the axis of the push rod, so that the first locking tooth moves away from the second locking tooth, and the first locking tooth and the second locking tooth are no longer locked, so that the second housing is no longer locked by the push rod, thereby enabling the second housing to be opened, and then the battery located inside the second housing can be replaced.
[0009] In one possible implementation, the push rod has a first abutment portion on the side near the second housing, and the second housing has a second abutment portion on the side near the push rod.
[0010] According to the above-mentioned technical means, when the push rod is pushed, the first abutting part can abut against the second abutting part. At the same time, since the first abutting part and the second abutting part will interfere during the abutting process, the first abutting part can push the second abutting part away from the push rod. That is, the push rod can push the second housing away from the push rod, so that a gap appears between the second housing and the decorative ring, so that the user can open the second housing through the gap to replace the battery.
[0011] In one possible implementation, there are multiple first locking teeth and multiple second locking teeth, with one second locking tooth engaging with one first locking tooth.
[0012] According to the above-mentioned technical means, the connection between the push rod and the second housing can be made more reliable by engaging multiple first locking teeth and multiple second locking teeth, thus preventing the second housing from accidentally falling off.
[0013] In one possible implementation, the number of first locking teeth is two, and the number of second locking teeth is two.
[0014] According to the above-mentioned technical means, the connection between the push rod and the second housing can be made more reliable by engaging the two first locking teeth and the two second locking teeth, thus preventing the second housing from accidentally falling off.
[0015] In one possible implementation, the elastic element is a metal spring.
[0016] According to the above technical means, when the elastic element is a metal spring sheet, it can be compressed when it is squeezed by the push rod, and recover its deformation and push the push rod to reset when it is not squeezed by the push rod.
[0017] In one possible implementation, the elastic element is a spring.
[0018] According to the above technical means, when the elastic element is a spring, it can be compressed when it is squeezed by the push rod, and recover its deformation and push the push rod to reset when it is not squeezed by the push rod.
[0019] In one possible implementation, the vehicle key structure further includes a circuit board and a button, wherein the circuit board is disposed between the first housing and the inner cover, and is connected to the first housing. The button is disposed between the circuit board and the first housing, and is electrically connected to the circuit board.
[0020] According to the above-mentioned technical means, the first housing can be pressed to activate the button located between the first housing and the circuit board, thereby triggering the corresponding function.
[0021] In one possible implementation, the vehicle key structure further includes a seal disposed between the circuit board and the first housing, and the seal is connected to the first housing.
[0022] According to the above-mentioned technical means, the seal disposed between the circuit board and the first housing can fill the gap between the first housing and the circuit board, thereby preventing liquid from flowing from the gap between the seal and the circuit board onto the circuit board.
[0023] In one possible implementation, the push rod includes a push rod body and a first end, wherein the first end is connected to the push rod body and the diameter of the first end is larger than the diameter of the push rod body.
[0024] According to the above-mentioned technical means, when pushing the push rod, force can be applied to the first end with a larger diameter, and the first end can easily push the push rod.
[0025] In one possible implementation, the push rod further includes a connecting portion disposed away from the first end.
[0026] According to the above technical means, the elastic element can be connected to the connecting part of the push rod to ensure that the push rod can squeeze the elastic element during the process of being pushed, and at the same time, the push rod can be driven to reset when the elastic element recovers its deformation.
[0027] In one possible implementation, the inner cover is provided with a limiting portion, and a portion of the elastic element is located within the limiting portion.
[0028] According to the above technical means, part of the elastic element can be inserted into the limiting groove to fix the elastic element and ensure that the elastic element can remain stable during the stress process. Attached Figure Description

Detailed Implementation
[0034] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0035] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0036] As vehicles become increasingly intelligent, smart keys are now commonplace, replacing traditional mechanical keys. Smart keys require batteries for use, and these batteries need to be replaced when depleted. However, current smart keys have complex structures, making disassembly difficult when replacing the battery.
[0037] To address the problem of complex smart key structures and high disassembly difficulty, this application provides a vehicle key structure.
[0038] like Figure 1 As shown, the vehicle key structure 100 provided in this application includes a first housing 11 and a second housing 12, and an inner cover 13 disposed between the first housing 11 and the second housing 12. Both the first housing 11 and the second housing 12 are engaged with the inner cover 13, such that the first housing 11, the second housing 12, and the inner cover 13 constitute the main structure of the vehicle key structure 100.
[0039] It should be noted that the connection between the first housing 11, the second housing 12, and the inner cover 13 can be a snap-fit connection. For example, the first housing 11 has a hook, and the inner cover 13 has a locking hole. When the first housing 11 and the inner cover 13 are fastened together, the hook extends into the locking hole and engages with it, thereby achieving the connection between the first housing 11 and the inner cover 13. Alternatively, the first housing 11 and the inner cover 13 can also be connected and fixed by screws; this is not limited here.
[0040] Based on this, the vehicle key structure 100 provided in this application also includes a decorative ring 14. The decorative ring 14 is disposed along the outer periphery of the first housing 11 and the second housing 12, and the decorative ring 14 is snapped into the second housing 12 and also snapped into the first housing 11. The decorative ring 14 is used to further connect and fix the first housing 11 and the second housing 12, ensuring a reliable connection between the first housing 11 and the second housing 12, thereby forming a stable cavity between the first housing 11 and the second housing 12 to provide installation space for other components of the vehicle key structure 100 and to protect the components located therein.
[0041] like Figure 1 As shown, the inner side of the decorative ring 14 is provided with a first hook 141, and the inner cover 13 is provided with a second hook 131 on the side near the decorative ring 14. The first hook 141 and the second hook 131 are engaged to realize the engagement between the decorative ring 14 and the inner cover 13, thereby connecting the first shell 11, the second shell 12 and the inner cover 13 with the decorative ring 14 to form a whole.
[0042] See Figure 2 and Figure 3 The vehicle key structure 100 provided in this application also includes a push rod 21, which is disposed between the second housing 12 and the inner cover 13. A first locking tooth 210 is provided on the side of the push rod 21 near the second housing 12. Based on this, a second locking tooth 120 is provided on the side of the second housing 12 near the push rod 21, and the second locking tooth 120 engages with the first locking tooth 210.
[0043] Based on this, the vehicle key structure 100 provided in this application also includes an elastic element 22, which is arranged along the axial direction of the push rod 21, and one end of the elastic element 22 is connected to the push rod 21, and the other end is connected to the inner cover 13.
[0044] In this way, when the push rod 21 is pushed towards the inner cover 13 along its length (i.e., along the X direction in the figure), the first locking tooth 210 on the push rod 21 no longer engages with the second locking tooth 120 on the second housing 12. This allows the second housing 12 to disengage from the push rod 21, enabling its removal and disassembly of the vehicle key structure 100, thus facilitating battery replacement. When the external force applied to the push rod 21 is removed, the elastic element 22 is no longer compressed. The elastic element 22 pushes the push rod 21 back to its original position, allowing the first locking tooth 210 of the push rod 21 to engage again with the second locking tooth 120 of the second housing 12.
[0045] In addition, it should be noted that the battery of the vehicle key structure 100 can be located between the second housing 12 and the inner cover 13, so that the battery can be replaced when the second housing 12 is opened.
[0046] In addition, such as Figure 2 As shown, the decorative ring 14 has a through hole 140, which is positioned opposite to the push rod 21. This allows the push rod 21, located between the first housing 11 and the second housing 12, to be contacted through the through hole 140, thereby pushing the push rod 21. For example, a push pin can be used to abut against the push rod 21 to push it. It should be noted that the through hole 140 and the push rod 21 being positioned opposite each other means that the axis of the through hole 140 coincides with the axis of the push rod 21. This allows the push pin to contact the push rod 21 when it is inserted into the through hole 140, thus pushing the push rod 21.
[0047] like Figure 2 As shown, the push rod 21 is provided with a first abutting part 211 on the side near the second housing 12, and the second housing 12 is provided with a second abutting part 121 on the side near the push rod 21.
[0048] In this way, when the push rod 21 is pushed along the X direction, the first abutting part 211 can abut against the second abutting part 121. At the same time, since the first abutting part 211 and the second abutting part 121 will interfere during the abutting process, the first abutting part 211 can push the second abutting part 121 away from the push rod 21. That is, when the push rod 21 is pushed along the X direction, the push rod 21 can push the second housing 12 away from the push rod 21, so that a gap appears between the second housing 12 and the decorative ring 14, so that the user can open the second housing 12 through the gap to replace the battery.
[0049] In some embodiments of this application, the elastic element 22 can be a metal spring sheet, with one end of the metal spring sheet connected to the push rod 21 and the other end connected to the inner cover 13. In this way, when the push rod moves in the X direction, the metal spring sheet is compressed. After the external force on the push rod 21 is removed, the metal spring sheet is no longer compressed and returns to its shape. The metal spring sheet pushes the push rod 21 to reset so that the push rod 21 can be engaged with the second housing 12 again.
[0050] In some other embodiments of this application, the elastic element 22 may also be a spring, with one end of the spring connected to the push rod 21 and the other end connected to the inner cover 13. In this way, when the push rod moves in the X direction, the spring is compressed. After the external force on the push rod 21 is removed, the spring is no longer compressed and returns to its shape. The spring pushes the push rod 21 to reset so that the push rod 21 can be engaged with the second housing 12 again.
[0051] like Figure 2 As shown, in some embodiments of this application, there can be multiple first locking teeth 210 and multiple second locking teeth 120, with one second locking tooth 120 engaging with one first locking tooth 210.
[0052] In this way, by engaging multiple first locking teeth 210 and multiple second locking teeth 120, the engagement between the push rod 21 and the second housing 12 can be made more stable, ensuring that the second housing 12 will not open accidentally.
[0053] In some embodiments, there can be two first locking teeth 210, and correspondingly, there can also be two second locking teeth 120. In this way, the first locking teeth 210 and the second locking teeth 120 correspond to each other, making the engagement between the push rod 21 and the second housing 12 more stable.
[0054] like Figure 1 As shown, the vehicle key structure 100 provided in this application also includes a circuit board 31 and a button 32. The circuit board 31 is disposed between the first housing 11 and the inner cover 13, and is connected to the first housing 11, for example, by a snap-fit mechanism between the circuit board 31 and the first housing 11. The button 32 is disposed between the circuit board 31 and the first housing 11, and is electrically connected to the circuit board 31.
[0055] In this way, the vehicle key structure 100 provided in this application can press the first housing 11 and thus activate the button 32 located between the first housing 11 and the circuit board 31, thereby triggering the corresponding function.
[0056] Based on this, such as Figure 1 As shown, the vehicle key structure 100 provided in this application also includes a seal 33, which is disposed between the circuit board 31 and the first housing 11, and is connected to the first housing 11.
[0057] In this way, the seal 33 disposed between the circuit board 31 and the first housing 11 can fill the gap between the first housing 11 and the circuit board 31, thereby preventing liquid from flowing from the gap between the first housing 11 and the circuit board 31 onto the circuit board 31.
[0058] In some embodiments of this application, the seal 33 may be made of an elastic rubber material. Alternatively, the seal 33 may also be made of other elastic plastics.
[0059] See Figure 2 The push rod 21 includes a push rod body 2100 and a first end 2101. The first end 2101 is connected to the push rod body 2100, and the diameter of the first end 2101 is larger than the diameter of the push rod body 2100.
[0060] In this way, when pushing the push rod 21, force can be applied to the first end 2101 with a larger diameter, and the first end 2101 can easily push the push rod 21.
[0061] See Figure 2The push rod 21 also includes a connecting part 2102, which is disposed away from the first end 2101.
[0062] In this way, the elastic element 22 can be connected to the connecting part 2102 of the push rod 21, ensuring that the push rod 21 can squeeze the elastic element 22 during the process of the push rod 21 being pushed, and at the same time, the push rod 21 can be driven to reset when the elastic element 22 recovers its deformation.
[0063] For example, the connecting part 2102 of the push rod 21 can be connected to the metal spring by adhesive bonding. When the elastic element 22 is a spring, the spring can be sleeved on the connecting part 2102, so that the spring is connected to the push rod 21.
[0064] Based on this, in order to limit the other end of the elastic member 22, the inner cover 13 is provided with a limiting part 130, and part of the elastic member 22 is located in the limiting part 130. For example, the limiting part 130 can be a limiting groove, so that part of the elastic member 22 can be inserted into the limiting groove, which can fix the elastic member 22 and ensure that the elastic member 22 can remain stable during the process of being subjected to force.
[0065] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
