Switch button, interior light and vehicle

Abstract

The application provides a switch key, an in-vehicle lamp and a vehicle, and relates to the technical field of vehicle parts. The switch key comprises an assembly shell and a key seat. The assembly shell has a mounting groove. At least one guide piece and at least one error prevention piece are arranged on the groove wall surface of the mounting groove. At least one sliding piece and at least one matching piece are arranged on the outer circumferential surface of the key seat. During the assembly of the switch key, the key seat needs to be assembled in the mounting groove, and one sliding piece is slidingly matched with a corresponding guide piece, and one matching piece is plug-in matched with a corresponding error prevention piece, so that the key seat can slide along the extension direction of the center line relative to the assembly shell. Since the guide piece and the error prevention piece are asymmetrically arranged about the center line, the key seat can only be assembled in the mounting groove in one form, that is, only when the key seat is in the correct mounting position, the sliding piece and the matching piece can be matched with the guide piece and the error prevention piece respectively, and the misassembly of the switch key can be prevented.

Description

Technical Field

[0001] This application relates to the field of vehicle component technology, and in particular to a switch button, an interior light fixture, and a vehicle. Background Technology

[0002] Currently, vehicles are usually equipped with interior lighting systems. When passengers or drivers need lighting, they can turn on the lights by pressing the switch button on the interior lights to illuminate the interior space.

[0003] In related technologies, such indoor lighting fixtures are often equipped with multiple switches, each controlling the on / off function of a specific location's light fixture. Each switch is also marked with a different icon for identification. However, because these switches are highly similar in appearance, incorrect assembly can easily occur during actual assembly. Utility Model Content

[0004] In view of this, embodiments of this application provide a switch button, an interior light fixture, and a vehicle to solve the technical problem that incorrect installation is prone to occur during the actual assembly of the switch button.

[0005] In a first aspect, this application provides a switch button, which includes: The assembly housing has a mounting groove, the mounting groove having a center line and a groove wall extending around the center line, the groove wall being provided with at least one guide and at least one anti-misalignment component, the guide and the anti-misalignment component being arranged at intervals along the circumference of the mounting groove; A button base is assembled in the mounting slot. The button base has an outer peripheral surface extending around the center line. At least one sliding member and at least one mating member are provided on the outer peripheral surface. The sliding member and the mating member are arranged at intervals along the circumference of the button base. In this configuration, one of the sliding members slides into a corresponding guide member, and one of the mating members plugs into a corresponding anti-misalignment member. The guide member and the anti-misalignment member are asymmetrically arranged about the center line.

[0006] Thus, when the button base is assembled in the mounting slot, a sliding component slides into a corresponding guide component, and a mating component inserts into a corresponding anti-misalignment component, allowing the button base to slide relative to the mounting shell along the extension direction of the center line. Since the guide component and the anti-misalignment component are asymmetrically arranged about the center line, the button base can only be assembled in the mounting slot in one form. That is, only when the button base is in the correct installation position can the sliding component and the mating component be mated with the guide component and the anti-misalignment component respectively, which can prevent the switch button itself from being misinstalled.

[0007] Specifically, during the assembly of the switch button, the assembly shell is usually fixed on the worktable. The button base is assembled into the mounting groove along the extension direction of the center line, and the sliding parts and mating parts are ensured to cooperate with the guide parts and the anti-misalignment parts respectively. Only then can the button base be correctly assembled onto the assembly shell, and the assembly of the switch button be completed.

[0008] In the above assembly process, the state in which the button base can be correctly installed in the mounting slot is defined as the first state. The state after rotating the button base in the first state 90° around the center line is defined as the second state. The state after rotating the button base in the first state 180° around the center line is defined as the third state. The state after rotating the button base in the first state 270° around the center line is defined as the fourth state. Because the guide and the anti-misalignment component are asymmetrically arranged about the center line, the sliding component and the mating component can only mate with the guide and the anti-misalignment component respectively when the button base is in the first state. When the button base is in the second, third, or fourth state, the sliding component and the mating component cannot be assembled at the same time, thereby preventing the switch button itself from being misassembled.

[0009] As an optional implementation, the number of guide members is two, the two guide members are arranged circumferentially spaced along the mounting groove, and the two guide members are symmetrically arranged about the center line.

[0010] Understandably, in order to ensure that the switch button can be used normally, the button holder can slide up and down along the extension direction of the center line in the mounting groove. Users control the indoor lights by pressing the button holder. Therefore, it is necessary to ensure that the button holder can slide stably along the extension direction of the center line.

[0011] In this embodiment, two guide members are provided on the wall of the mounting groove, and the two guide members are symmetrically arranged about the center line. Two sliding members are provided on the outer peripheral surface of the key seat. The two sliding members slide with the two guide members respectively. By forming a set of sliding engagements on the opposite sides of the key seat, the key seat can slide stably in the mounting groove.

[0012] As an optional implementation, the tank wall includes a first wall, a second wall, a third wall, and a fourth wall connected in sequence. The first wall is connected to the fourth wall, the first wall is opposite to and parallel to the third wall, and the second wall is opposite to and parallel to the fourth wall. The number of the anti-misalignment components is two, and the two anti-misalignment components are respectively disposed on the first wall surface and the third wall surface, and the two guide components are respectively disposed on the second wall surface and the fourth wall surface.

[0013] Thus, by placing the two anti-misalignment components on different sides, misassembly can be further prevented, and the mating components can slide with the anti-misalignment components, so that the first wall, second wall, third wall and fourth wall can all form a sliding fit with the button base, allowing the button base to slide more stably along the extension direction of the center line.

[0014] As an optional implementation, one of the anti-misalignment component and the mating component is a slide groove, which extends along the extension direction of the center line and has an inlet / outlet port. The slide groove is connected to the mounting groove. The other of the anti-misalignment component and the mating component is a rib, which is slidably inserted into the slide groove along the extension direction of the center line and can enter and exit the slide groove through the inlet / outlet port.

[0015] Thus, taking the anti-misalignment component as a groove and the mating component as a rib as an example, the groove is formed by the recessed groove wall of the mounting groove, allowing the groove to communicate with the mounting groove. The groove extends along the center line to the groove opening end of the mounting groove, forming an inlet / outlet port at the groove opening end. The outer periphery of the button base protrudes outward to form a rib, which extends along the center line and slides into the groove. When the button base is pressed, the rib can enter and exit the groove through the inlet / outlet port, so that the anti-misalignment component can not only prevent the switch button itself from being misaligned, but also make the button base more stable to install.

[0016] As an optional implementation, the inlet / outlet port is provided with a guide surface, which is connected to the inner surface of the slide groove, and the guide surface is used to guide the protruding rib to be inserted into the slide groove.

[0017] Thus, by providing a guide surface at the inlet / outlet port, and connecting the guide surface to the inner surface of the slide groove, the guide surface can guide the protruding rib to be inserted into the slide groove when assembling the switch button, so that the button base can be assembled into the mounting slot more smoothly, reducing the assembly difficulty.

[0018] As an optional implementation, the rib has a first portion and a second portion arranged along the extension direction of the center line, and the width of the first portion is smaller than the width of the second portion; The rib is inserted into the groove along the direction from the second part toward the first part.

[0019] Thus, the width of the first part is smaller than the width of the inlet / outlet port. When assembling the switch button, the rib with the smaller width of the first part is inserted into the slide groove from the inlet / outlet port first, and then the wider second part is inserted into the slide groove from the inlet / outlet port. This can further facilitate the insertion and engagement of the rib and the slide groove, and the second part can form a sliding engagement with the slide groove, so that the rib and the slide groove can continue to maintain a sliding engagement.

[0020] In some embodiments, the slide has a first groove segment and a second groove segment arranged along the extension direction of the center line, and the groove width of the first groove segment is smaller than the groove width of the second groove segment. The inlet and outlet port is located on the side of the second groove segment away from the first groove segment. When assembling the switch button, the first part with the smaller rib width is inserted into the second groove segment from the inlet and outlet port first. Then, the first part passes through the second groove segment and extends into the first groove segment, and the second part is inserted into the second groove segment from the inlet and outlet port. At this time, the first part can form a sliding fit with the first groove segment, and the second part can also form a sliding fit with the second groove segment, so that the rib can slide more stably along the slide.

[0021] In addition, since the width of the second part is greater than the width of the first slot, when assembling the switch button, if the second part of the rib is inserted into the second slot from the inlet / outlet port first, the second part cannot continue to extend into the first slot after it extends into the second slot because the width of the second part is greater than the width of the first slot. As a result, the rib cannot be inserted into the slide groove in the direction from the first part to the second part, so that the rib can only be inserted into the slide groove in the direction from the second part to the first part, which can further prevent the switch button itself from being misassembled.

[0022] As an optional implementation, the rib has a transition portion that connects the first portion and the second portion, and the width of the transition portion gradually decreases along the direction from the second portion toward the first portion.

[0023] It is understandable that when assembling the switch button, since the first part of the rib with a smaller width is inserted into the slide groove from the inlet / outlet port first, and then the second part with a larger width is inserted into the slide groove from the inlet / outlet port, the second part may get stuck at the inlet / outlet port after the first part extends into the slide groove, which will prevent the rib from being inserted into the slide groove smoothly and affect the assembly efficiency.

[0024] Thus, the transition section connects the first part and the second part, and the width of the transition section gradually decreases along the direction from the second part to the first part, so that the transition section can play a transition role. After the switch button is assembled and the first part is inserted into the slide, the transition section can guide the second part to be inserted into the slide, thereby preventing the second part from getting stuck at the inlet / outlet port, so that the protrusion can be smoothly inserted into the slide and improve assembly efficiency.

[0025] As an optional implementation, the projection shape of the guide member on the first plane is different from the projection shape of the anti-misalignment member on the first plane, and the first plane is perpendicular to the center line.

[0026] In this way, the guide component cannot cooperate with the mating component, and the anti-misalignment component cannot cooperate with the sliding component. When assembling the switch button, the guide component can only cooperate with the sliding component one by one, and the anti-misalignment component can only cooperate with the mating component. This can further prevent the switch button itself from being misassembled.

[0027] Secondly, this application also provides an interior lighting fixture, which includes a lamp housing, a lamp panel, and a switch button as described above. The lamp panel and the switch button are both disposed on the lamp housing, and the switch button is used to control the lamp panel to turn on and off.

[0028] The vehicle interior lighting provided in this application improves the assembly efficiency of the vehicle interior lighting by using the aforementioned switch button, and also prevents assembly errors of the vehicle interior lighting.

[0029] Thirdly, this application also provides a vehicle including a body and the aforementioned interior lighting fixtures, the interior lighting fixtures being mounted on the body.

[0030] The vehicle provided in this application, by adopting the aforementioned interior lighting fixtures, achieves low manufacturing costs and good performance. Attached Figure Description

[0033] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0034] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0035] Currently, vehicles are usually equipped with an interior lighting system. When passengers or the driver need lighting, they can turn on the lights by pressing the switch button 10 on the interior light to illuminate the interior space.

[0036] In related technologies, such indoor lighting fixtures are often equipped with multiple switch buttons 10, each corresponding to control the on / off function of the lighting fixture at a specific location. Each switch button 10 is also distinguished by different icons on its surface. However, because the multiple switch buttons 10 are highly similar in shape and structure, incorrect assembly can easily occur during actual assembly.

[0037] Based on this, this application provides a switch button 10, an interior light fixture, and a vehicle. During the assembly of the switch button 10, the button base 2 needs to be assembled into the mounting groove 11, and a sliding member 22 is slidably engaged with a corresponding guide member 12, and a mating member 23 is inserted into a corresponding anti-misalignment member 13, so that the button base 2 can slide relative to the mounting shell 1 along the extension direction of the center line N. Since the guide member 12 and the anti-misalignment member 13 are asymmetrically arranged about the center line N, the button base 2 can only be assembled into the mounting groove 11 in one form. That is, only when the button base 2 is in the correct installation position can the sliding member 22 and the mating member 23 be engaged with the guide member 12 and the anti-misalignment member 13 respectively, which can prevent the switch button 10 from being misassembled.

[0038] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.

[0039] Please see Figures 1 to 5 , Figure 1 This is a three-dimensional structural diagram of the switch button provided in an embodiment of this application. Figure 2 This is a top view showing the button holder correctly installed in the mounting slot according to an embodiment of this application. Figure 3 This is a top view of the button base provided in this embodiment after rotating 90° around its center line. Figure 4 This is a top view of the button holder provided in this embodiment after being rotated 180° around its center line. Figure 5 This is a top view of the button holder provided in this embodiment after rotating 270° around the center line.

[0040] As shown in the figure, this embodiment provides a switch button 10, which includes an assembly shell 1 and a button base 2. The assembly shell 1 has a mounting groove 11, which has a center line N and a groove wall surface 111 extending around the center line N. At least one guide member 12 and at least one anti-misalignment member 13 are provided on the groove wall surface 111. The guide member 12 and the anti-misalignment member 13 are arranged at intervals along the circumference of the mounting groove 11. The button base 2 is assembled in the mounting groove 11. The button base 2 has an outer peripheral surface 21 extending around the center line N. At least one sliding member 22 and at least one mating member 23 are provided on the outer peripheral surface 21. The sliding member 22 and the mating member 23 are arranged at intervals along the circumference of the button base 2. Among them, one sliding member 22 is slidably engaged with a corresponding guide member 12, and one mating member 23 is inserted into a corresponding anti-misalignment member 13. The guide member 12 and the anti-misalignment member 13 are asymmetrically arranged about the center line N.

[0041] Optionally, the mounting groove 11 has a groove end, the shape of which can be a circle, square, regular polygon, or other centrally symmetrical shape. The center line N passes through the midpoint of the groove end. The cross-sectional shape of the groove wall 111 of the mounting groove 11 is the same as the shape of the groove end. The cross-sectional shape of the outer peripheral surface 21 of the button base 2 is adapted to the shape of the groove end, so that the button base 2 can be assembled in the mounting groove 11 along the extension direction of the center line N.

[0042] In this embodiment, the guide 12, the anti-misalignment component 13, the slider 22, and the mating component 23 all extend along the extension direction of the center line N. When the button base 2 is assembled in the mounting groove 11, one slider 22 slides in cooperation with one corresponding guide 12, and one mating component 23 inserts in cooperation with one corresponding anti-misalignment component 13, so that the button base 2 can slide relative to the mounting shell 1 along the extension direction of the center line N. Since the guide 12 and the anti-misalignment component 13 are asymmetrically arranged about the center line N, the button base 2 can only be assembled in the mounting groove 11 in one form. That is, only when the button base 2 is in the correct installation position can the slider 22 and the mating component 23 be mated with the guide 12 and the anti-misalignment component 13 respectively, which can prevent the switch button 10 from being misassembled.

[0043] Specifically, during the assembly of the switch button 10, the assembly shell 1 is usually fixed on the workbench. The button base 2 is assembled into the mounting groove 11 along the extension direction of the center line N, and the sliding part 22 and the mating part 23 are ensured to cooperate with the guide part 12 and the anti-misalignment part 13 respectively. Only then can the button base 2 be correctly assembled onto the assembly shell 1, and the assembly of the switch button 10 be completed.

[0044] In the above assembly process, the state in which the button base 2 can be correctly installed in the mounting slot 11 is defined as the first state. The state after rotating the button base 2 in the first state 90° around the center line N is defined as the second state. The state after rotating the button base 2 in the first state 180° around the center line N is defined as the third state. The state after rotating the button base 2 in the first state 270° around the center line N is defined as the fourth state. Since the guide 12 and the anti-misalignment component 13 are asymmetrically arranged about the center line N, the sliding component 22 and the mating component 23 can only be mated with the guide 12 and the anti-misalignment component 13 respectively when the button base 2 is in the first state. When the button base 2 is in the second, third or fourth state, the sliding component 22 and the mating component 23 cannot be assembled at the same time, thereby preventing the switch button 10 from being misassembled.

[0045] It should be noted that there are generally two situations where switch buttons 10 are misinstalled. Taking switch button A and switch button B as examples, one situation is that switch button A is installed in the wrong position, resulting in misinstallation. The other situation is that switch button A is installed in the same position as switch button B, and switch button B is installed in the same position as switch button A, resulting in mixed installation of switch buttons A and B. To deal with the second situation, the anti-misinstallation component 13 on different switch buttons 10 can be designed with different shapes, or the anti-misinstallation component 13 on different switch buttons 10 can be placed in different positions to prevent mixed installation.

[0046] Please see Figure 1 In some embodiments, there are two guide members 12, which are arranged circumferentially at intervals along the mounting groove 11 and are symmetrical about the center line N.

[0047] Understandably, in order to ensure that the switch button 10 can be used normally, the button base 2 can slide up and down in the mounting groove 11 along the extension direction of the center line N. The user controls the indoor lights by pressing the button base 2. Therefore, it is necessary to ensure that the button base 2 can slide stably along the extension direction of the center line N.

[0048] In this embodiment, two guide members 12 are provided on the groove wall 111 of the mounting groove 11, and the two guide members 12 are symmetrically arranged about the center line N. Two sliding members 22 are provided on the outer peripheral surface 21 of the button seat 2. The two sliding members 22 are slidably engaged with the two guide members 12 respectively. By forming a set of sliding engagements on the opposite sides of the button seat 2, the button seat 2 can slide stably in the mounting groove 11.

[0049] In some other implementations, the switch button 10 also includes a reset element disposed between the button base 2 and the mounting housing 1, and the reset element is used to drive the button base 2 back to the position before it was pressed, so as to facilitate the user to press the button base 2.

[0050] Please see Figure 1 and Figure 6 , Figure 6This is a three-dimensional structural diagram of the assembly shell provided in an embodiment of this application. In some embodiments, the groove wall surface 111 includes a first wall surface 1111, a second wall surface 1112, a third wall surface 1113, and a fourth wall surface 1114 connected in sequence. The first wall surface 1111 and the fourth wall surface 1114 are connected. The first wall surface 1111 and the third wall surface 1113 are opposite to and parallel to each other. The second wall surface 1112 and the fourth wall surface 1114 are opposite to and parallel to each other. There are two anti-misalignment components 13. The two anti-misalignment components 13 are respectively disposed on the first wall surface 1111 and the third wall surface 1113. The two guide components 12 are respectively disposed on the second wall surface 1112 and the fourth wall surface 1114.

[0051] Optionally, the mounting groove 11 is a square groove, and the groove wall 111 includes a first wall 1111, a second wall 1112, a third wall 1113, and a fourth wall 1114 connected in sequence. The first wall 1111, the second wall 1112, the third wall 1113, and the fourth wall 1114 are all square surfaces. The first wall 1111 and the third wall 1113 are opposite to and parallel to each other, and the second wall 1112 and the fourth wall 1114 are opposite to and parallel to each other. Two guide members 12 are respectively disposed on the second wall 1112 and the fourth wall 1114, and the two guide members 12 are symmetrically disposed about the center line N. Two anti-misalignment members 13 are respectively disposed on the first wall 1111 and the third wall 1113. By disposing of the two anti-misalignment members 13 on different sides, misinstallation can be further prevented.

[0052] In this embodiment, the mating part 23 can slide with the anti-misoperation part 13, so that the first wall surface 1111, the second wall surface 1112, the third wall surface 1113 and the fourth wall surface 1114 can all form a sliding fit with the button base 2, so that the button base 2 can slide more stably along the extension direction of the center line N.

[0053] Please see Figure 1 and Figure 6 In some embodiments, one of the anti-misalignment component 13 and the mating component 23 is a slide groove 131, which extends along the extension direction of the center line N and has an inlet / outlet port 1311. The slide groove 131 communicates with the mounting groove 11. The other of the anti-misalignment component 13 and the mating component 23 is a rib 231, which is slidably inserted into the slide groove 131 along the extension direction of the center line N and can enter and exit the slide groove 131 through the inlet / outlet port 1311.

[0054] Optionally, taking the anti-misalignment component 13 as a groove 131 and the mating component 23 as a rib 231 as an example, the groove wall 111 of the mounting groove 11 is recessed to form the groove 131, so that the groove 131 can communicate with the mounting groove 11, and the groove 131 extends along the extension direction of the center line N to the groove end of the mounting groove 11, so that the groove 131 can form an inlet / outlet port 1311 at the groove end. The outer peripheral surface 21 of the button base 2 protrudes outward to form a rib 231, the rib 231 extends along the extension direction of the center line N, and the rib 231 is slidably inserted into the groove 131. When the button base 2 is pressed, the rib 231 can enter and exit the groove 131 through the inlet / outlet port 1311, so that the anti-misalignment component 13 can not only prevent the switch button 10 itself from being misinstalled, but also make the button base 2 more stable.

[0055] In some other embodiments, the groove wall 111 of the mounting groove 11 may be formed with a protruding rib 231, and the outer peripheral surface 21 of the button base 2 may be formed with a recessed sliding groove 131. Through the insertion and cooperation of the protruding rib 231 and the sliding groove 131, it is possible to prevent the switch button 10 from being misinstalled and to make the button base 2 more stable.

[0056] Please see Figure 1 and Figure 6 In some embodiments, the inlet / outlet port 1311 is provided with a guide surface 1312, which is connected to the inner surface of the slide groove 131. The guide surface 1312 is used to guide the protruding rib 231 to be inserted into the slide groove 131.

[0057] Thus, by providing a guide surface 1312 at the inlet / outlet port 1311, and connecting the guide surface 1312 to the inner surface of the slide groove 131, the guide surface 1312 can guide the protruding rib 231 to be inserted into the slide groove 131 when assembling the switch button 10, so that the button base 2 can be assembled more smoothly into the mounting groove 11, reducing the assembly difficulty.

[0058] In this embodiment, the guide surface 1312 can be an arc surface. When assembling the switch button 10, one end of the protruding rib 231 slides in contact with the guide surface 1312. The arc surface of the guide surface 1312 can more smoothly guide the protruding rib 231 into the mounting groove 11, making the assembly process smoother. In some other embodiments, the guide surface 1312 can also be a slope, so that the guide surface 1312 can also play the role of guiding the protruding rib 231 into the slide groove 131, and can also reduce the manufacturing difficulty.

[0059] In some embodiments, the end of the protruding rib 231 that is inserted into the slide groove 131 may have a contact surface, which is adapted to cooperate with the guide surface 1312. When assembling the switch button 10, the guide surface 1312 slides into contact with the contact surface, and the guide surface 1312 and the contact surface together guide the protruding rib 231 to be inserted into the slide groove 131, further reducing the assembly difficulty.

[0060] Please see Figure 1 , Figure 6 and Figure 7 In some embodiments, the rib 231 has a first portion 2311 and a second portion 2312 arranged along the extension direction of the center line N, and the width of the first portion 2311 is smaller than the width of the second portion 2312, wherein the rib 231 is inserted into the groove 131 along the direction of the second portion 2312 toward the first portion 2311.

[0061] Thus, the width of the first part 2311 is smaller than the width of the inlet / outlet port 1311. When assembling the switch button 10, the rib 231 with the smaller width of the first part 2311 is first inserted into the slide groove 131 from the inlet / outlet port 1311, and then the larger width of the second part 2312 is inserted into the slide groove 131 from the inlet / outlet port 1311. This further facilitates the insertion and engagement of the rib 231 and the slide groove 131, and the second part 2312 can form a sliding engagement with the slide groove 131, so that the rib 231 and the slide groove 131 can continue to maintain a sliding engagement.

[0062] In some embodiments, the slide 131 has a first groove segment and a second groove segment arranged along the extension direction of the center line N, and the groove width of the first groove segment is smaller than the groove width of the second groove segment. The inlet / outlet port 1311 is located on the side of the second groove segment away from the first groove segment. When assembling the switch button 10, the first part 2311 with a smaller width of the rib 231 is first inserted into the second groove segment from the inlet / outlet port 1311. Then, the first part 2311 passes through the second groove segment and extends into the first groove segment, and the second part 2312 is inserted into the second groove segment from the inlet / outlet port 1311. At this time, the first part 2311 can form a sliding fit with the first groove segment, and the second part 2312 can also form a sliding fit with the second groove segment, so that the rib 231 can slide more stably along the slide 131.

[0063] Furthermore, since the width of the second part 2312 is greater than the width of the first slot, when assembling the switch button 10, if the second part 2312 of the protrusion 231 is first inserted into the second slot from the inlet / outlet port 1311, the second part 2312 cannot continue to extend into the first slot after it extends into the second slot, so the protrusion 231 cannot be inserted into the slide groove 131 in the direction from the first part 2311 to the second part 2312. This allows the protrusion 231 to be inserted into the slide groove 131 only in the direction from the second part 2312 to the first part 2311, which can further prevent the switch button 10 from being misassembled.

[0064] Please see Figure 7 In some embodiments, the rib 231 has a transition portion 2313 that connects the first portion 2311 and the second portion 2312, and the width of the transition portion 2313 gradually decreases along the direction from the second portion 2312 toward the first portion 2311.

[0065] It is understandable that when assembling the switch button 10, since the first part 2311 with a smaller width is inserted into the slide groove 131 from the inlet port 1311 first, and then the second part 2312 with a larger width is inserted into the slide groove 131 from the inlet port 1311, the second part 2312 may get stuck at the inlet port 1311 after the first part 2311 extends into the slide groove 131, causing the rib 231 to be unable to be smoothly inserted into the slide groove 131, thus affecting the assembly efficiency.

[0066] Thus, the transition portion 2313 connects the first part 2311 and the second part 2312, and the width of the transition portion 2313 gradually decreases along the direction from the second part 2312 toward the first part 2311, so that the transition portion 2313 can play a transition role. After the switch button 10 is assembled and the first part 2311 extends into the slide groove 131, the transition portion 2313 can guide the second part 2312 to extend into the slide groove 131, thereby preventing the second part 2312 from getting stuck at the inlet / outlet port 1311, so that the protruding rib 231 can be smoothly inserted into the slide groove 131, improving assembly efficiency.

[0067] It should be noted that, since the width of the second groove is greater than the width of the first part 2311, when the first part 2311 extends into the second groove, the first part 2311 may get stuck at the connection between the second groove and the first groove, causing the rib 231 to be unable to be smoothly inserted into the slide groove 131, thus affecting the assembly efficiency.

[0068] Thus, the slide groove 131 can also have a transition groove connecting the first groove segment and the second groove segment. When the first part 2311 extends into the second groove segment, the transition groove can guide the first part 2311 into the first groove segment, thereby preventing the first part 2311 from getting stuck at the connection between the second groove segment and the first groove segment, improving assembly efficiency. In addition, the transition groove can also be adapted to the transition part 2313 of the protruding rib 231, so that the protruding rib 231 is more stably assembled in the slide groove 131.

[0069] In some embodiments, the projection shape of the guide member 12 on the first plane is different from the projection shape of the anti-misalignment member 13 on the first plane, and the first plane is perpendicular to the center line N.

[0070] Optionally, the projection shape of the guide member 12 on the first plane is circular. In order to ensure that the slider 22 can form a sliding fit with the guide member 12, the projection shape of the slider 22 on the first plane is also circular. The projection shape of the anti-misalignment member 13 on the first plane is square. In order to ensure that the mating member 23 can form a plug-in fit with the anti-misalignment member 13, the projection shape of the mating member 23 on the first plane is also square.

[0071] Thus, the guide 12 cannot cooperate with the mating part 23, and the anti-misalignment part 13 cannot cooperate with the sliding part 22. When assembling the switch button 10, the guide 12 can only cooperate with the sliding part 22 in a one-to-one sliding manner, and the anti-misalignment part 13 can only cooperate with the mating part 23 in a plug-in manner, which can further prevent the switch button 10 from being misassembled.
