Description

Technical Field

[0001] The present disclosure relates to the field of vehicle accessories, and in particular, to a vehicle key. Background Art

[0002] In a vehicle remote control key that adopts a folding key blade, the ejection of the key blade is achieved by the torsion spring pushing the rotor to rotate when the button is pressed to unlock. Because the existing torsion spring solution has both the function of applying torque and the function of applying a resilient force to the release button, the button always has a pre-tightening force against the single-side shell of the key handle under the action of the torsion spring elastic force. After being assembled into a finished key, this pre-tightening force will cause the opening of the shell on both sides to deform, resulting in a large gap in appearance and a poor appearance. At the same time, in this assembly method, there will be a gap between the rotor and the button in the direction of rotation, and the rotor will be loose after installation, affecting the user experience. Utility Model Content

[0003] The purpose of the present disclosure is to provide a vehicle key to reduce the gap between the rotor and the key handle housing and button, solve the problems of loose rotor fit and key handle deformation, and improve user experience.

DETAILED DESCRIPTION

[0040] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0041] In the present disclosure, unless otherwise specified, directional words such as "inner" and "outer" are defined with respect to the outline of the corresponding component. The use of the terms "first", "second", etc. is intended to distinguish different components and does not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.

[0042] In related technologies, such as Figure 1As shown, the key rotor 2' connected to the key blade is placed between the upper shell 11' and the lower shell 12' of the vehicle key, the button 3' passes through the upper shell 11' and is inserted into the key rotor 2', and the torsion spring 4' abuts between the button 3' and the lower shell 12', and provides torque and a resisting force at the same time. When the key blade is stored between the upper shell 11' and the lower shell 12', at this time, the button 3' is simultaneously engaged with the upper shell 11', and the button 3' cannot move. There is also a groove on the key rotor 2' that cooperates with the protrusion on the button 3', so the key rotor 2' is also restricted from rotating by the button 3'. At this time, the button 3' generates a pre-tightening force approaching the upper shell 11' under the action of the resisting force of the torsion spring 4'. The continuous pre-tightening force will cause the gap between the key rotor 2' and the lower shell 12' to become larger and larger, thereby causing the key to deform and affecting the user experience. In addition, since the torsion spring 4' does not contact the key rotor 2', the clamping connection between the button 3' and the key rotor 2' does not provide a circumferential resistance force to the two. Therefore, there will be a fitting gap between the button 3' and the key rotor 2' in the circumferential direction of the button 3', which will cause a certain degree of looseness during use, thereby affecting the user experience.

[0043] According to an embodiment of the present disclosure, a vehicle key is provided. Figures 2 to 9 As shown, the key handle 1 includes a first shell 11 and a second shell 12 that are arranged opposite to each other, the rotor 2 is rotatably arranged between the first shell 11 and the second shell 12, and a receiving cavity is formed inside the rotor 2, the button 3 can be inserted into the receiving cavity through the first shell 11, the elastic member 4 can be at least partially accommodated in the receiving cavity and abutted between the button 3 and the rotor 2, and the two ends of the torsion member 5 can be connected to the second shell 12 and the rotor 2, respectively, so that the vehicle key has a retracted state and an ejected state. In the retracted state, the two ends of the elastic member 4 abut against the button 3 and the rotor 2, respectively, and the button 3 and the end of the rotor 2 away from the second shell 12 abut against each other, and the button 3 is respectively clamped with the first shell 11 and the rotor 2 in the circumferential direction of the button 3, and the clamping method can be a magnetic clamping method or a convex groove matching clamping method, which is not limited in the present disclosure. At this time, the rotor 2 cannot rotate. In the pop-up state, the two ends of the elastic member 4 can respectively abut against the button 3 and the rotor 2, and when the button 3 is pressed, the button 3 is not engaged with the rotor 2 in the circumferential direction of the button 3, and the torsion member 5 can drive the rotor 2 to rotate. It should be noted that the rotor 2 is connected to the key blade 25, and in the retracted state, the key blade 25 is stored between the first shell 11 and the second shell 12, and in the pop-up state, the rotor 2 rotates to drive the key blade 25 to pop out of the key handle 1.

[0044] Through the above technical solution, the elastic member 4 and the torsion member 5 are connected to the rotor 2, and one end of the elastic member 4 directly pushes the rotor 2 toward the second shell 12, and the other end pushes the rotor 2 toward the first shell 11 through the button 3, thereby offsetting the pushing force of the rotor 2 only toward the single-side shell, eliminating the gap between the rotor 2 and the first shell 11 and the second shell 12 in the axial direction of the button 3, and effectively solving the deformation problem of the key handle 1. In addition, since the torsion member 5 directly cooperates with the rotor 2 and the key handle 1, the torsion member 5 always provides the rotor 2 with a torsion force in the circumferential direction of the button 3, and can also reduce the gap between the rotor 2 and the button 3 in the circumferential direction of the button 3, solve the problem of loose cooperation between the rotor 2 and the button 3, optimize the assembly effect, make the key handle 1, the rotor 2 and the button 3 cooperate more closely, and effectively improve the user experience.

[0045] Furthermore, if Figure 3 and Figure 4 As shown, the button 3 may include a first protrusion 31 and a second protrusion 32, the first housing 11 is provided with a first groove 111 that matches the first protrusion 31, the rotor 2 is provided with a second groove 21 that matches the second protrusion 32, the first groove 111 and the second groove 21 can be respectively stopped at the button 3 in the circumferential direction, the second groove 21 has an opening on the side close to the second housing 12, so that when the button 3 is extended into the accommodating cavity, the second protrusion 32 can be moved out of the second groove 21, and the side of the second groove 21 away from the second housing 12 is provided with a top wall that is mutually limited with the button 3, so that when the button 3 is extended out of the accommodating cavity, the button 3 is limited. Here, the side of the first groove 111 away from the second housing 12 can also be provided with a top wall that is mutually limited with the button 3, and the present disclosure does not limit this.

[0046] In the retracted state, the first protrusion 31 is located in the first groove 111, and the second protrusion 32 is located in the second groove 21, so that the button 3 is simultaneously clamped with the first shell 11 and the rotor 2 in the circumferential direction of the button 3, so that the first shell 11 can clamp the rotor 2 in the circumferential direction of the button 3 through the button 3. At this time, the rotor 2 can press the button 3 in the circumferential direction of the button 3, and the torsion member 5 cannot drive the rotor 2 to rotate. It should be noted that at this time, one end of the elastic member 4 presses against the rotor 2, providing a force to press the rotor 2 toward the second shell 12, and the other end presses against the button 3, providing a force to press the button 3 toward the rotor 2. When the second protrusion 32 is located in the second groove 21, the second groove 21 can limit the second protrusion 32 on the side of the button 3 close to the first shell 11 in the axial direction, so that the second protrusion 32 is pressed against the abutting wall of the second groove 21 under the action of the elastic member 4, so that the button 3 can be pressed against the rotor 2 and provide a force to press the rotor 2 toward the first shell 11, so that the force of the rotor 2 on the first shell 11 and the second shell 12 reaches a force balance state. At this time, the key blade 25 connected to the rotor 2 is located between the first shell 11 and the second shell 12.

[0047] If the key blade 25 is to be unlocked and ejected from the key handle 1, the button 3 is pressed to extend the button 3 into the accommodating cavity. At this time, the first protrusion 31 moves along the axial direction of the button 3 toward the second housing 12 until the first protrusion 31 is separated from the first groove 111. At this time, the vehicle key enters the ejection state, the button 3 is not engaged with the first housing 11, the rotor 2 loses the limit in the circumferential direction of the button 3, and the torsion member 5 drives the rotor 2 to rotate, so that the key blade 25 is ejected from the key handle 1. Here, the length of the first groove 111 in the axial direction of the button 3 can be the same as the length of the second groove 21 in the axial direction of the button 3. In this way, when the first protrusion 31 is separated from the first groove 111, the second protrusion 32 can also be separated from the second groove 21 synchronously, so that the button 3 will not be driven to rotate when the rotor 2 rotates. If the length of the second groove 21 is longer than the first groove, when the first protrusion 31 is separated from the first groove 111, although the rotor 2 can also rotate, it will drive the button 3 to rotate when the second groove 21 is engaged with the second protrusion 32.

[0048] Furthermore, if Fig. 9 As shown, the first protrusion 31 and the second protrusion 32 can be staggered in the axial and circumferential directions of the button 3, so that when the button 3 is pressed, the first protrusion 31 and the second protrusion 32 will not interfere with the corresponding structure on the rotor 2, thereby affecting the rotation of the rotor 2 driven by the torsion member 5.

[0049] According to one embodiment of the present disclosure, Figure 2 , Figure 3 and Figure 8 As shown, a through hole 20 communicating with the accommodating cavity is provided at intervals on one side of the rotor 2 close to the second housing 12, and the through hole 20 is arranged opposite to the second groove 21. The through hole 20 can facilitate the visual installation of the button 3 and the elastic member 4 from one side of the through hole 20 during installation, so that the matching installation of the second protrusion 32 and the second groove 21 is smoother. In addition, the opening of the through hole 20 can also reduce the weight of the rotor 2.

[0050] According to one embodiment of the present disclosure, Figure 3 and Figure 6 As shown, a third protrusion 112 may be formed on one side of the first housing 11 close to the rotor 2, and the third protrusion 112 can be inserted into the rotor 2 and arranged around the outside of the button 3. The third protrusion 112 can limit the rotor 2 in the radial direction of the button 3 to prevent the rotor 2 from shaking when rotating. In addition, the first groove 111 mentioned above can also be opened on the third protrusion 112, so that there is no additional groove on the surface of the first housing 11, which is not limited in the present disclosure.

[0051] According to one embodiment of the present disclosure, Figure 3 and Figure 4As shown, the torsion member 5 may be a torsion spring, and a third groove 121 may be provided on one side of the second housing 12 close to the rotor 2, and one end of the torsion spring may be provided in the third groove 121 and connected to the second housing 12, that is, the torsion spring may be partially provided in the third groove 121. A fourth groove 22 is provided on one side of the rotor 2 close to the second housing 12, and one end of the torsion spring may be provided in the fourth groove 22 and connected to the rotor 2, that is, the torsion spring may be partially provided in the fourth groove 22. The third groove 121 and the fourth groove 22 accommodate the torsion spring, which can reduce the gap between the second housing 12 and the rotor 2, and also limit the torsion spring itself to prevent the torsion spring from generating other displacements in non-torsion directions.

[0052] According to one embodiment of the present disclosure, Figure 3 and Figure 4 As shown, the button 3 may be a hollow structure, and the elastic member 4 is partially disposed in the hollow structure. In this way, the elastic member 4 is partially accommodated in the button 3, and the button 3 can limit the elastic member 4 in the radial direction of the elastic member 4, limit the movement trajectory of the elastic member 4, and prevent the elastic member 4 from sliding in the radial direction during the extension and retraction process.

[0053] According to one embodiment of the present disclosure, Figure 3 and Figure 4 As shown, the elastic member 4 may include a spring 41 and a top block 42, one end of the spring 41 may abut against the button 3, the top block 42 may be connected to the side of the spring 41 away from the button 3, the side of the rotor 2 close to the top block 42 is provided with a fifth groove 23, the top block 42 is partially disposed in the fifth groove 23, and can abut against the rotor 2. The top block 42 cooperates with the fifth groove 23 to prevent the top block 42 from sliding on the rotor 2 due to the bending of the spring 41 under the action of the abutting force when pressing, thereby indirectly affecting the ejection of the key blade 25 from the key handle 1 due to the pressure exerted by the top block 42 on the rotor 2, so that the top block 42 can exert a more stable force on the rotor 2, so that the key blade 25 can be ejected more stably.

[0054] Furthermore, if Figure 3 and Figure 4As shown, the top block 42 may include a cylindrical section 421 and an inverted cone section 422, one end of the spring 41 may be sleeved on the cylindrical section 421, the spring 41 may only be sleeved on the cylindrical section 421, or one end may be inserted into the cylindrical section 421 and connected to the cylindrical section 421 while being sleeved, and the present disclosure does not limit this. The large diameter end of the inverted cone section 422 is interconnected with the cylindrical section 421, that is, the inverted cone section 422 gradually decreases from the side close to the spring 41 to the side away from the spring 41, the apex of the inverted cone section 422 abuts against the bottom surface of the fifth groove 23, and the side wall of the inverted cone section 422 abuts against the edge of the fifth groove 23. The inverted cone section 422 can reduce the contact area between the spring 41 and the rotor 2, reduce the friction resistance, and concentrate the stress between the top block 42 and the rotor 2 when abutting, which can save more effort when pressing. In addition, the side wall of the inverted cone section 422 abuts against the edge of the fifth groove 23 to prevent the top block 42 from being displaced in a direction other than the extension and contraction direction of the spring 41, thereby playing a limiting role and making the button 3 more stable when pressed.

[0055] According to one embodiment of the present disclosure, Figures 5 to 8 As shown, a protrusion 24 may be provided on one side of the rotor 2 close to the key handle 1, and a slide groove 10 matching the protrusion 24 may be provided on the key handle 1. When the rotor 2 rotates, it may rotate along the extension track of the slide groove 10 to make the ejection of the key blade 25 more stable. Since the movement mode of the rotor 2 is rotation, the slide groove 10 may be an arc-shaped structure, the protrusion 24 may be a hemisphere or a polyhedron, and the cross-sectional shape of the groove wall of the slide groove 10 may also be an arc or polygon matching the shape of the protrusion 24, and the present disclosure does not limit this.

[0056] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0057] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0058] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
