[0003] At present, the light guide column in the conventional key structure is usually a rectangular columnar structure. When the key is produced, the light guide column is directly installed on the key. Since one end surface of the light guide column is exposed to the key to display the LED light on the key surface, in order to prevent the light guide column from falling off from the key, it is necessary to use a snap-on or interference fit method to install the light guide column in the key. This installation method has strict requirements on the installation distance between the two, which can easily cause the risk of the light guide column shaking or falling off. Utility Model Content

[0025] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0026] like Figures 1 to 6 As shown, an embodiment of the present application provides a key structure, which includes: a light guide column 10, including a light guide column body 11 and a limiting portion 12 connected at a preset angle; a key bracket 20, including a first accommodating portion 21 and a mounting portion 22, the first accommodating portion 21 passes through the key bracket 20, and is used to accommodate at least part of the light guide column 10, and the mounting portion 22 protrudes from the surface of the first accommodating portion 21, and is used to support the limiting portion 12; a key cap 30, which is detachably connected to the key bracket 20, and includes a second accommodating portion 31 and a supporting portion 32, the second accommodating portion 31 passes through the key cap 30 and accommodates the light guide column 10 together with the first accommodating portion 21, the supporting portion 32 protrudes from the surface of the second accommodating portion 31, and can form a clamping space 33 for clamping the limiting portion 12 together with the mounting portion 22; a PCB board 40, including an indicator light 41, and the indicator light 41 is positioned opposite to the light guide column 10.

[0027] In a specific implementation, the key structure of the present application includes a light guide column 10, a key bracket 20, a key cap 30 and a PCB board 40. The light guide column 10 includes a light guide column body 11 and a limit portion 12 connected at a preset angle. The light guide column body 11 is arranged relative to the indicator light 41 of the PCB board 40 and is accommodated in the first accommodation portion 21 of the key bracket 20 and the second accommodation portion 31 of the key cap 30. The light guide column body 11 can transmit the light of the indicator light 41 to the surface of the key structure for the driver to observe. 0 can be clamped in the clamping space 33 formed by the mounting portion 22 and the abutting portion 32. The mounting portion 22 is supported on the bottom of the limiting portion 12, and the abutting portion 32 can be abutted against the top of the limiting portion 12, thereby restricting the limiting portion 12 in the clamping space 33 and making it unable to move. The light guide column body 11 connected to the limiting portion 12 at a preset angle is also unable to move. Therefore, after the light guide column 10 is installed as a whole between the key bracket 20 and the key cap 30 of the key structure, there will be no risk of shaking or falling off.

[0028] Furthermore, when the key support 20 and key cap 30 are in a separate state, the light guide 10 is first placed on the mounting portion 22, so that the mounting portion 22 supports the bottom of the limiting portion 12. Subsequently, the abutting portion 32 of the key cap 30 is abutted against the top of the limiting portion 12, completing the assembly of the mounting portion 22 and the abutting portion 32. At this time, the limiting portion 12 is also clamped within the clamping space 33 formed by the mounting portion 22 and the abutting portion 32, thereby performing a limiting function. Therefore, by respectively arranging the mounting portion 22 and the abutting portion 32 on the key support 20 and the key cap 30, it is possible to facilitate the disassembly and installation of the entire key structure.

[0029] Specifically, the preset connection angle between the light guide body 11 and the limiting portion 12 is greater than 0 degrees and less than 180 degrees. When the light guide body 11 and the limiting portion 12 are connected at this angle, the limiting portion 12 can act as a limiter, preventing the light guide body 11 from sliding along its own extension direction, thereby fixing the entire light guide 10 within the key structure. Preferably, the light guide body 11 and the limiting portion 12 are connected at a 90-degree angle. This vertical connection has the best limiting effect and can effectively prevent the risk of the light guide 10 shaking or falling off.

[0030] like Figure 1 and Figure 6 As shown, the key structure of the embodiment of the present application, wherein the light guide column 10 includes two limiting portions 12, and the two limiting portions 12 are respectively arranged on both sides of the light guide column body 11, and the thickness of the two limiting portions 12 is different along the extension direction of the light guide column body 11; the key bracket 20 has two mounting portions 22, and the key cap 30 has two abutting portions 32. In the assembled state of the key structure, the two mounting portions 22 and the two abutting portions 32 are correspondingly arranged to form two clamping spaces 33 with different heights, and the two limiting portions 12 are respectively clamped in the two clamping spaces 33.

[0031] In specific implementation, because the two limiting portions 12 have different thicknesses along the extension direction of the light guide body 11, and the two sandwiching spaces 33 for mounting the two limiting portions 12 have different heights, when sequentially mounting the light guide 10 and the key cap 30 on the key bracket 20, the two limiting portions 12 must first be aligned with the two mounting portions 22. After the light guide 10 is mounted, the two abutting portions 32 of the key cap 30 must also be aligned with the corresponding two limiting portions 12 to complete the overall assembly of the key structure. During the assembly process, the two limiting portions 12 of different thicknesses serve as a positioning mechanism, preventing the light guide 10 and the key cap 30 from being misaligned.

[0032] like Figure 1 and Figure 6As shown, the key structure of an embodiment of the present application, wherein, along the extension direction of the light guide column body 11, the bottom surfaces of the two limiting parts 12 are at the same height, and the top surfaces are at different heights, the two mounting parts 22 are at the same height and supported on the bottom surfaces of the two limiting parts 12, and the two abutting parts 32 are respectively abutted against the top surfaces of the two limiting parts 12.

[0033] During specific implementation, the two mounting portions 22 of the button bracket 20 are at the same height, which can support the two limiting portions 12 whose bottom surfaces are at the same height. Moreover, there is no height difference between the two mounting portions 22, and the button bracket 20 does not need to increase its height to set the mounting portion 22, thereby avoiding the overall height of the button structure being too large and making more reasonable use of space in the car.

[0034] like Figure 4 and Figure 5 As shown, the key structure of the embodiment of the present application, wherein the first accommodating portion 21 and the second accommodating portion 31 both have a plurality of crushing protrusions 23 protruding from their own surfaces, and the cross-section of the crushing protrusions 23 is a pointed-angle structure. In the assembled state of the key structure, the crushing protrusions 23 with pointed-angle structures are crushed by the light guide column 10 and embedded in the surface of the light guide column 10.

[0035] In specific implementation, the surfaces of the first accommodating portion 21 and the second accommodating portion 31 have multiple crushing protrusions 23, and the cross-section of the crushing protrusion 23 is a pointed-angle structure. During the process of the light guide column 10 being installed into the first accommodating portion 21 and the second accommodating portion 31, it will contact the pointed-angle part of the crushing protrusion 23, and squeeze and crush the pointed-angle part of the crushing protrusion 23, so that the pointed-angle part forms a planar structure and is embedded in the surface of the light guide column 10, thereby making the installation of the light guide column 10 in the first accommodating portion 21 and the second accommodating portion 31 more secure.

[0036] like Figure 4 and Figure 5 As shown, the crushing protrusion 23 can be installed at any position on the surface of the first accommodating portion 21 and the second accommodating portion 31, including the various surfaces of the installation portion 22 and the various surfaces of the abutting portion 32, so that when the limiting portion 12 is installed in the clamping space 33, it is not easy to slide out of the clamping space 33, and the limiting portion 12 can have a better limiting effect on the light guide column body 11.

[0037] like Figure 4 As shown, the key structure of an embodiment of the present application, wherein the mounting portion 22 further includes a sliding surface 221, the sliding surface 221 is arranged at an angle of the mounting portion 22 toward the light guide column 10, and the extension direction of the sliding surface 221 is at a preset angle to the extension direction of the light guide column body 11.

[0038] In specific implementation, the sliding surface 221 is arranged at the angle of the mounting portion 22 facing the light guide column 10, and is arranged at an angle. When the light guide column 10 is installed in the first accommodating portion 21 and is offset, the bottom of the light guide column body 11 contacts the sliding surface 221 and slides along the sliding surface 221, so that the light guide column body 11 can slide in the correct direction, thereby completing the complete installation of the light guide column 10 in the first accommodating portion 21. Therefore, the sliding surface 221 plays an auxiliary installation role.

[0039] Optionally, the included angle of the abutting portion 32 may also be configured as an inclined surface that extends obliquely. When the key cap 30 is mounted on the light guide column 10 , the inclined surface may also serve as an auxiliary mounting aid.

[0040] like Figure 1 and Figure 2 As shown, in the key structure of the embodiment of the present application, in the assembled state of the key structure, the end surface of the light guide body 11 facing the key cap 30 and the display surface 34 on the top of the key cap 30 are in the same plane.

[0041] In specific implementation, after the key structure is assembled, the end face of the light guide column body 11 facing the key cap 30 is in the same plane as the display surface 34 on the top of the key cap 30, that is, the end face of the light guide column body 11 will not protrude from the display surface 34, nor will it be recessed from the display surface 34. Since the driver usually presses the display surface 34 to operate the key, such a setting can ensure the driver's key feel when pressing, and avoid the protruding or recessed light guide column body 11 affecting the key operation.

[0042] like Figure 2 As shown, the key structure of an embodiment of the present application, wherein the key bracket 20 also includes a light-transmitting portion 24 arranged therethrough, the light-transmitting portion 24 is used to connect the key cap 30 and the PCB board 40, and the light-transmitting portion 24 is separated from the first accommodating portion 21 by a light-shielding plate 25.

[0043] In a specific implementation, the light-transmitting portion 24 can transmit the light through other light sources on the PCB board 40 to the key cap 30 and display it on the display surface 34 of the key cap 30 so that the driver can observe other driving information.

[0044] Typically, the color of the light transmitted through the light-transmitting portion 24 is different from the color of the light transmitted by the light-guiding column 10 in the first accommodating portion 21. By setting a light-shielding plate 25 to separate the light-transmitting portion 24 and the first accommodating portion 21, the phenomenon of light crosstalk between the two can be avoided, and the mutual influence between the indicator light of the light-guiding column 10 and the indicator light of other parts of the pattern on the display surface 34 can be avoided.

[0045] The key structure of the embodiment of the present application, wherein the key cap 30 has a display portion 35 made of a light-transmitting material, and the display portion 35 is arranged opposite to the light-transmitting portion 24, so that the light passing through the light-transmitting portion 24 can pass through the display portion 35 opposite to the light-transmitting portion 24 and be displayed on the display surface 34 to be observed by the driver.

[0046] like Figure 2 On the display surface 34 of the key cap 30 shown, the display portion 35 is the indicated pattern portion, and the light transmitted through the light-transmitting portion 24 can make the pattern of the display portion 35 illuminate, so that the driver can observe it.

[0047] like Figures 1 to 3 As shown, the key structure of the embodiment of the present application further includes: a buffer pad 50, which is made of a transparent soft material. The buffer pad 50 is arranged between the key bracket 20 and the PCB board 40. The buffer pad 50 includes a plurality of third accommodating portions 51. The third accommodating portions 51 protrude toward the key bracket 20, and the third accommodating portions 51 are an internal hollow structure. The plurality of third accommodating portions 51 are used to accommodate the indicator lights 41 and other components of the PCB board 40.

[0048] In specific implementation, the setting of the buffer pad 50 can provide protection for the PCB board 40, so that when the light guide column 10, the key bracket 20 and the key cap 30 are installed on the PCB board 40 and when the user presses the key, it will not cause excessive impact on the PCB board 40, thereby improving the overall service life of the key structure; the setting of the third accommodating portion 51 is used to provide accommodating space and protection for the indicator light 41 and other components of the PCB board 40.

[0049] Specifically, the buffer pad 50 is made entirely of silicone material, which has sufficient buffering and light-transmitting effects. While playing a protective role, it can also allow the light of the indicator light 41 to penetrate.

[0050] An embodiment of the present application also provides a vehicle, wherein the vehicle includes the above-mentioned button structure.

[0051] In a specific implementation, the vehicle of the embodiment of the present application includes a key structure, which includes a light guide column 10, a key bracket 20, a key cap 30 and a PCB board 40. The light guide column 10 includes a light guide column body 11 and a limit portion 12 connected at a preset angle. The light guide column body 11 is arranged relative to the indicator light 41 of the PCB board 40 and is accommodated in the first accommodation portion 21 of the key bracket 20 and the second accommodation portion 31 of the key cap 30. The light guide column body 11 can transmit the light of the indicator light 41 to the surface of the key structure for the driver to observe. It can be observed that the limiting portion 12 of the light guide column 10 can be clamped in the clamping space 33 formed by the mounting portion 22 and the abutting portion 32. The mounting portion 22 is supported on the bottom of the limiting portion 12, and the abutting portion 32 can be abutted against the top of the limiting portion 12, thereby restricting the limiting portion 12 in the clamping space 33 and making it unable to move. The light guide column body 11 connected to the limiting portion 12 at a preset angle is also unable to move. Therefore, after the light guide column 10 is installed as a whole between the key bracket 20 and the key cap 30 of the key structure, there will be no risk of shaking or falling off.

[0052] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
