Description

Technical Field

[0001] The utility model relates to the technical field of automobile intelligent keys, in particular to a universal joint applied to a button of an automobile intelligent key and a component thereof. Background Art

[0002] Since the 21st century, people's clothing, food, housing and transportation have undergone earth-shaking changes, and cars have basically become one of the necessary means of transportation for people to travel. With the development of electronic information technology, the degree of intelligence in cars has become higher and higher, and car smart keys are also an important part of smart cars. Car smart keys can not only control the opening and closing of car doors, but also can park and warm up the car with one button as they develop. People are pursuing more and more diversified functions of car smart keys. A single button that can only be turned in a single direction can no longer meet the growing functional needs. Often a single button needs to be pressed in multiple directions.

[0003] In order to realize that a single button can meet the requirements of Anton in multiple directions at the same time, a universal joint auxiliary assembly design is added to the button assembly design in the prior art. By assembling the button on the rotating shafts on both sides of the universal joint, the button has the freedom to rotate up and down along the rotating shaft of the universal joint, and then the other two sides of the universal joint are assembled to the rotating shaft of the mounting shell, so that the universal joint has the freedom to rotate up and down along the rotating shaft of the mounting shell, thereby jointly realizing the freedom of rotation of the button in four directions. However, such a multi-directional implementation method of the button has the following problems. The assembly of the button and the rotating shaft requires the design of the unilateral buckling amount of the button and the unilateral shape variable of the mounting hole, so that the button can be assembled with the universal joint. When the universal joint is installed in the mounting shell, the unilateral buckling amount and unilateral shape variable of the universal joint also need to be designed. When the assembly of the button and the universal joint, and the assembly of the universal joint and the mounting shell need to consider the unilateral buckle amount and the unilateral type variable, the universal joint needs to increase the installation guide angle to avoid the difficulty of installing the button and the mounting shell. At the same time, the mounting hole at the universal joint and the button and the mounting hole between the universal joint and the mounting shell cannot be designed to be too thick to avoid insufficient deformation and inability to fully install. Therefore, the universal joint assembly of the automobile smart key provided in the prior art has technical problems such as difficult installation, insufficient strength of the universal joint, difficulty in disassembly, and easy breakage at the installation. Utility Model Content

[0004] The utility model aims at solving the technical problems in the prior art of difficult installation of universal joint structural components, insufficient strength of the universal joint, easy breakage at the installation point, etc., and provides a universal joint and its components applied to a car smart key button, which at least have the advantages of being easy to install and having a high strength of the universal joint structure.

[0005] First aspect

[0006] The utility model provides a universal joint applied to a car smart key button, comprising: an annular hollow shell, a key position accommodating structure and a shell limiting structure;

[0007] The key position accommodating structure is arranged on two opposite sides of the outer periphery of the hollow shell;

[0008] The shell limiting structure is arranged on two opposite sides of the inner circumference of the hollow shell;

[0009] Wherein, the key position accommodating structure and the shell limiting structure are arranged in different positions in the hollow shell.

[0010] One of the concepts of the utility model is to construct the universal joint into an annular hollow shell, and use its inner and outer circumferences to install with the button and the mounting shell respectively, so as to improve the overall structural strength of the universal joint and reduce the degree of limitation of the installation of the universal joint. It is worth understanding that the existing universal joint is constructed in a cross shape, and is connected with the button and the mounting shell respectively through the outer circumference of the universal joint. This installation method easily leads to the limitation of the appearance design of the universal joint, and the outer circumference of the universal joint also serves as the bearing structure of the button and the mounting shell, so that the universal joint must sacrifice part of the structural strength and design the mounting hole to be thinner, which poses a risk of breakage. The universal joint provided in the utility model uses the outer circumference and inner circumference of the universal joint for the button and the mounting shell to be installed respectively, so that the universal joint can be designed in an annular style to improve its structural strength. At the same time, a special key position accommodating structure and a shell limiting structure are set according to the installation requirements of the button and the mounting shell, so as to reduce the difficulty of installing the button and the mounting shell.

[0011] Furthermore, the key position accommodating structure includes: an accommodating hole penetrating the hollow shell, and a guide groove sinking inwardly along the side surface of the hollow shell;

[0012] The guide groove is arranged around the accommodating hole and extends outward from the accommodating hole to a side edge of the hollow shell.

[0013] Specifically, the guide groove can guide the installation of the key, making assembly more convenient.

[0014] Furthermore, the guide groove extends outward from the accommodating hole to form a gradually larger opening.

[0015] Optionally, the shell limiting structure includes: a protruding rotating shaft and limiting blocks arranged in the hollow shell and located on both sides of the rotating shaft.

[0016] Specifically, the mounting shell is limited by the rotating shaft and the protrusion, so that the assembly between the mounting shell and the universal joint no longer uses the crude snap-on structure, and the installation is simpler.

[0017] Furthermore, the limit block is constructed as a right triangle, the right-angled side of which is arranged to fit the inner wall of the hollow shell, and the hypotenuse of which faces the rotating shaft.

[0018] Optionally, the housing limiting structure includes: a guide rail;

[0019] The guide rail narrows inward from the limit block and extends to the rotating shaft.

[0020] Optionally, the rotating shaft is constructed in a circular shape, and its side opposite to the limiting block is flattened inward to form a positioning platform.

[0021] Second aspect

[0022] The utility model provides a universal joint assembly applied to a car smart key button, comprising a universal joint applied to a car smart key button as provided in any embodiment of the first aspect, a button and a mounting shell;

[0023] The key is accommodated in the key position accommodating structure;

[0024] The mounting shell is combined with the universal joint through the shell limiting structure.

[0025] Furthermore, the button includes a button portion and a receiving portion connected to the button portion, and the receiving portion is used to receive the key position receiving structure.

[0026] Optionally, adapted to the shape of the hollow shell, the mounting shell includes an outer shell, an inner shell, and a connecting structure connecting the outer shell and the inner shell;

[0027] When the mounting shell is assembled to the hollow shell, the outer shell covers the outer periphery of the hollow shell, and the inner shell is fixedly connected to the inner periphery of the hollow shell through the shell limiting structure.

[0028] In summary, the utility model provides a universal joint and its components for automobile smart key buttons. The utility model constructs the universal joint as an annular hollow shell, and uses its inner and outer circumferences to be installed with the button and the mounting shell respectively, thereby improving the overall structural strength of the universal joint and reducing the degree of limitation of the universal joint installation. It is worth understanding that the existing universal joint is cross-shaped, and is connected with the button and the mounting shell respectively through the outer circumference of the universal joint. This installation method easily leads to the limitation of the appearance design of the universal joint, and the outer circumference of the universal joint is also used as the bearing structure of the button and the mounting shell, so that the universal joint must sacrifice part of the structural strength, and the mounting hole is designed to be thinner, so there is a risk of breakage. The universal joint provided in the utility model uses the outer circumference and inner circumference of the universal joint for the button and the mounting shell to be installed, so that the universal joint can be designed as an annular style to improve its structural strength. At the same time, a special key position accommodating structure and a shell limiting structure are set according to the installation requirements of the button and the mounting shell, reducing the difficulty of installing the button and the mounting shell.

[0034] The following is combined with Figures 1 to 3 , the utility model is described in detail.

[0035] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0036] See also Figure 1 Shown is a structural schematic diagram of a universal joint 1 and its components in the prior art provided by the utility model.

[0037] In the prior art, the universal joint 1 is configured as a cross-shaped structure because the universal joint 1 matches the installation of the key 2 and the installation shell 3 through the outer periphery. The two opposite sides of the outer periphery of the cross-shaped structure are configured with a raised shaft 121 structure for the key 2 to be installed (see Figure 1 A), and the other two opposite sides of the outer periphery of the cross-shaped structure are constructed with sunken installation grooves for the insertion of the housing shaft 121 (see Figure 1 B). In order for the universal joint 1 to limit the button 2 and the mounting shell 3 respectively, the protruding height of the rotating shaft 121 cannot be made too high, so as to avoid the deformation being too small to enter the mounting groove set in the mounting shell 3, and the rotating shaft 121 needs to be provided with a guide structure with a certain cut angle for guiding the rotating shaft 121 to be installed in the mounting shell 3. At the same time, the button 2 must also be provided with a mounting protrusion adapted to the mounting groove of the universal joint 1, and the protruding height of the protrusion cannot be set too large, and a cut angle structure for guidance is also required. Such a structural design in the prior art will lead to the following problems: 1. The depth of the universal joint 1 installed in the mounting shell 3 and the depth of the button 2 installed in the universal joint 1 are not enough, resulting in an unstable mounting structure; 2. When the button 2 is installed in the universal joint 1 and the universal joint 1 is installed in the mounting shell 3, the raised shaft 121 part needs to be installed in the mounting hole. An overly small cut-angle structure may easily lead to installation difficulties. In addition, since the button 2 and the shaft 121 of the universal joint 1 both require a certain amount of deformation, the button 2 and the shaft 121 of the universal joint 1 may easily break during the installation process; 3. The universal joint 1 is a cross structure with many angles, the structural strength is insufficient, and the parts are relatively fragile as a whole.

[0038] In order to solve these problems existing in the universal joint 1 of the prior art, the utility model redesigns the structure of the universal joint 1. Figure 2 The figure is a schematic structural diagram of a universal joint 1 applied to a smart key button 2 of a car provided by an embodiment of the utility model.

[0039] Specifically, the universal joint 1 provided by the utility model is an annular hollow shell, and the shell is designed as an integral molding, and the structural strength is high. At the same time, in order to realize the design of the hollow shell, the utility model changes the connection structure of the universal joint 1 to be assembled with the button 2 through the outer periphery of the hollow shell, and assembled with the mounting shell 3 through the inner periphery of the hollow shell, while improving the structural strength of the universal joint 1, the volume of the universal joint 1 can be reduced to 70% of the original, reducing the overall volume of the car smart key.

[0040] Furthermore, the button 2 is assembled through a button 2 accommodating structure.

[0041] Furthermore, the button 2 accommodating structure includes an accommodating hole 111 that passes through the hollow shell, and a guide groove 112 that sinks inward along the side of the hollow shell; the guide groove 112 is arranged around the accommodating hole 111 and extends outward from the accommodating hole 111 to a side edge of the hollow shell.

[0042] Furthermore, the guide groove 112 extends outward from the receiving hole 111 to form a gradually enlarged opening.

[0043] Specifically, the button 2 will enter the receiving hole 111 from the opening of the guide groove 112, which reduces the difficulty of installing the button 2 and makes the installation of the button 2 easier.

[0044] Optionally, the shell limiting structure 12 includes: a protruding rotating shaft 121 and limiting blocks 122 arranged in the hollow shell and located on both sides of the rotating shaft 121 .

[0045] Furthermore, the limit block 122 is constructed as a right triangle, the right-angled side of which is arranged to fit the inner wall of the hollow shell, and the hypotenuse of which faces the rotating shaft 121.

[0046] Optionally, the housing limiting structure 12 includes: a guide rail 123;

[0047] The guide rail 123 narrows inward from the limiting block 122 and extends to the rotating shaft 121 .

[0048] Optionally, the rotating shaft 121 is constructed in a circular shape, and the side opposite to the limiting block 122 is flattened inward to form a positioning platform.

[0049] Specifically, the mounting shell 3 is deformed by the guidance of the guide rail 123 and enters the limit block 122, and then recovers its deformation after passing through the limit block 122. It is simultaneously limited by the rotating shaft 121 and the limit block 122, so that the mounting shell 3 is fixed to the universal joint 1, thereby reducing the difficulty of assembling the mounting shell 3 and the universal joint 1.

[0050] In order to illustrate the structure of the universal joint 1 assembly provided by the utility model, please refer to Figure 3 The figure shows a structural schematic diagram of a universal joint 1 component applied to a car smart key button 2 provided by the utility model.

[0051] Specifically, the key 2 is a normal circular structure, including a key 2 and a receiving portion connected to the key 2, and the receiving portion is used to be received in the key receiving structure 11. Thanks to the design of the guide groove 112 of the universal joint 1, the key 2 does not need to be fixed to the receiving hole 111 by snapping, and can directly enter the receiving hole 111 through the guide groove 112 to complete the installation of the key 2 (see Figure 3 C), there is no need to design an angled guide structure and a reserved deformation amount, which reduces the risk of damage to the key 2 and makes the assembly of the key 2 easier.

[0052] Furthermore, adapted to the shape of the hollow shell, the mounting shell 3 includes an outer shell, an inner shell and a connecting structure connecting the outer shell and the inner shell; when the mounting shell 3 is assembled in the hollow shell, the outer shell covers the outer periphery of the hollow shell, and the inner shell is fixedly connected to the inner periphery of the hollow shell through the shell limiting structure 12.

[0053] Specifically, the mounting shell 3 is no longer the original enclosing structure design, but is adapted to the structure of the hollow shell of the universal joint 1, and is designed as a plug-in structure, so that the assembly and combination between the mounting shell 3 and the universal joint 1 is better. At the same time, the mounting shell 3 is designed as a long strip bayonet with a certain deformation. Under the guidance of the guide, it is deformed and enters the limit block 122, and then after completely entering the limit block 122, it is deformed and fixed in the limit block 122. At the same time, the rotating shaft 121 will also limit the mounting shell 3, so as to achieve the fastening of the mounting shell 3 and the universal joint 1.

[0054] In addition, the outer cover of the mounting shell 3 is adapted to the shape of the guide groove 112 and is designed with a raised bump. After the mounting shell 3 is assembled with the universal joint 1, the bump will be accommodated in the guide groove 112 to complete the positioning and fixation of the button 2.

[0055] The utility model is described in detail above. The utility model uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
