[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0028] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present invention should have the usual meanings understood by people with ordinary skills in the field to which this application belongs. The "first", "second" and similar words used in this application do not indicate any order, quantity or importance, but are only used to distinguish different components.

[0029] As the automotive industry develops more and more fiercely, the switches in vehicles are becoming more and more diverse. However, the functional configurations required by each car model are different. In order to reflect the uniqueness of each car, this will result in the need to develop a new set of switches for each car. Even due to different operating habits, the switch function layout of left-hand and right-hand drive models will be different. For the convenience of the driver, the functions frequently operated by the driver are arranged on the side close to the driver. This will result in the development of a separate set of switches for right-hand drive models, increasing development costs. In addition, with after-sales replacement parts, if a certain button fails, the entire switch needs to be replaced. In fact, most of the parts are normal, which will cause a lot of waste and increase the cost of the vehicle's switches.

[0030] Based on this, the present application proposes a switch assembly and a vehicle to solve the problem of increased cost of switches in vehicles in the prior art.

[0031] Hereinafter, the present application will be described in detail through one or more specific embodiments. Figure 1 and Figure 2 Shown, including:

[0032] The switch body 10 includes a switch housing 11 and a first circuit board 12 located in the switch housing 11. The first circuit board 12 is provided with a first connection portion 121 connected to a controller for enabling the switch assembly to perform control functions.

[0033] A plurality of key assemblies 20 are separately located in the switch housing 11 and independently and detachably connected to the switch housing 11. The key assemblies 20 include a second connecting portion 21 and a key conductive portion 22. The second connecting portion 21 is connected to the first connecting portion 121.

[0034] When subjected to external pressure, the key conductive portion 22 abuts against the second connecting portion 21 to be electrically connected to the first connecting portion 121 and generate an electrical signal for representing the function of the key assembly 20 .

[0035] Specifically, the first circuit board 12 and the button assembly 20 are both located in the switch housing 11. The first connecting portion 121 of the first circuit board 12 is connected to the second connecting portion 21 of the button assembly 20. When the button conductive portion 22 is subjected to external pressure, it abuts against the second connecting portion 21, and then the button conductive portion 22 is connected to the first connecting portion 121. The first connecting portion 121 generates an electrical signal that matches the button conductive portion 22 and transmits it to the controller. The controller executes a function adapted to the button assembly 20 based on the received electrical signal. The electrical signal can be a voltage, and the controller performs different functional operations based on different voltages.

[0036] The first connecting part 121 and the second connecting part 21 are both configured as plugs or one is a plug and the other is a socket, and the pins on the plug correspond one-to-one to the holes on the socket (the number of pins on the plug can be two or three). When the key conductive part 22 abuts against the second connecting part 21, the key conductive part 22 is conductive to the first connecting part 121.

[0037] In the present application, each key assembly 20 is an independent switch subassembly. The function realization, position adjustment and key replacement of the key assembly 20 are not affected or restricted by other key assemblies 20.

[0038] In addition, the button assembly 20 is detachably connected to the switch housing 11. When the button assembly 20 breaks down, only one button assembly 20 needs to be replaced without replacing the entire switch of the vehicle, which greatly reduces the cost of the vehicle on the switch. Moreover, since the button assembly 20 is detachably connected to the switch housing 11 and the function corresponding to the button assembly 20 is only related to the resistance of the button conductive portion 22 included in the button assembly 20, the position of the button assembly 20 with different functions on the switch housing 11 can also be flexibly adjusted according to usage requirements, which greatly reduces the cost of vehicle switch development.

[0039] It should be noted that the button assembly 20 can be provided in plurality to enhance the functional diversity of the switch assembly.

[0040] In this embodiment, a key assembly 20 and a first circuit board 12 are disposed within a switch housing 11. A first connection portion 121 is provided on the first circuit board 12, which is connected to a controller for controlling the switch assembly. A key conductive portion 22 and a second connection portion 21 connected to the first connection portion 121 are provided on the key assembly 20. When subjected to external pressure, the key conductive portion 22 abuts against the second connection portion 21, thereby conducting electrical current with the first connection portion 121. This allows the first connection portion 121 to generate an electrical signal representing the function of the key assembly 20 based on the key conductive portion 22 and transmit it to the controller. The controller then performs a corresponding control operation based on the electrical signal, thereby controlling the switch assembly to perform the relevant operation. The key conductive portion 22 in the key assembly 20 corresponds to the function of the key assembly 20. The key assembly 20 is detachably connected to the switch housing 11. In the event of a failure of the key assembly 20, a new key assembly 20 with the same function can be replaced. This facilitates mass production and widespread application of the key assembly 20 and reduces vehicle switch costs.

[0041] In some embodiments, as Figure 2 As shown, the button assembly 20 also includes a button housing 23 and a second circuit board 24. The second circuit board 24 and the button conductive part 22 are both located in the button housing 23. One end of the second connecting part 21 is located on the second circuit board 24, and the other end protrudes from the button housing 23 and is connected to the first connecting part 121. The button conductive part 22 is located on the side of the second circuit board 24 away from the first connecting part 121.

[0042] Specifically, one end of the second connecting part 21 is a fixed end located on the second circuit board 24, and the other end is a free end passing through the button housing 23 and connected to the first connecting part 121. A gold-plated disk is provided on the side of the second circuit board 24 away from the first connecting part 121, and the gold-plated disk is connected to the second connecting part 21 on the other side. When the key conductive part 22 abuts against the gold-plated disk, the key conductive part 22 abuts against the second connecting part 21, and the key conductive part 22 conducts the first connecting part 121. The provision of the gold-plated disk can ensure that the key conductive part 22 can abut against the second connecting part 21 when it is close to the second circuit board 24 to conduct the first connecting part 121, thereby avoiding the need for the key conductive part 22 and the second connecting part 21 to abut one-to-one during use, which is beneficial to improving the practicality of the key assembly 20.

[0043] In addition, electronic components such as LED lights are also provided on the second circuit board 24. When the button conductive portion 22 abuts against the second connecting portion 21 and conducts the first connecting portion 121, the LED light is turned on to prompt the user that the button is pressed.

[0044] In this embodiment, by arranging the second circuit board 24 and the key conductive part 22 in the key housing 23, the second connecting part 21 located on the second circuit board 24 passes through the key housing 23 and contacts and connects with the first connecting part 121, so that the key assembly 20 forms an independent standard structure, which is convenient for users to replace the key assembly 20, and also convenient for accessing and placing the key assembly 20, thereby improving the practicality of the key assembly 20.

[0045] Based on the above embodiment, the button housing 23 may be further defined as follows:

[0046] In some embodiments, the button housing 23 includes a detachably connected button base 231 and a button shell 232, the button base 231 is provided with a through hole for the second connecting part 21 to pass through, the button shell 232 is provided with a through groove for the top rod 223 to pass through, and the second circuit board 24, the conductive part 221 and the shift block 222 are located between the button shell 232 and the button base 231.

[0047] In some embodiments, as Figure 2 As shown, the button conductive portion 22 includes a conductive member 221, a stop block 222, and a push rod 223 sequentially arranged in the button housing 23. The conductive member 221 is arranged close to the second circuit board 24. A conductive protrusion 2211 is provided on the conductive member 221. The stop block 222 is arranged opposite to the conductive protrusion 2211.

[0048] When the top rod 223 is subjected to external pressure, the blocking block 222 presses the conductive protrusion 2211 to move toward the side of the conductive member 221 away from the top rod 223 until it abuts against the second connecting portion 21 on the second circuit board 24, so that the blocking block 222 is connected to the first connecting portion 121.

[0049] Specifically, the conductive member 221 is fixedly connected to the second circuit board 24. A gap exists between the conductive protrusion 2211 on the conductive member 221 and the second connecting portion 21 on the second circuit board 24. When the push rod 223 presses the stop block 222, the stop block 222 presses the conductive protrusion 2211, and the conductive protrusion 2211 approaches and abuts against the second connecting portion 21. The stop block 222 conducts electricity to the first connecting portion 121 through the conductive protrusion 2211 and the second connecting portion 21. The abutment between the conductive protrusion 2211 and the second connecting portion 21 is elastic, that is, in the absence of external pressure, the conductive protrusion 2211 automatically moves away from the second connecting portion 21 until it is no longer in contact with the second connecting portion 21 (the conductive protrusion 2211 may be a conductive rubber mushroom head with an automatic rebound function).

[0050] In addition, the shift block 222 is positioned on the conductive member 221 through the axial hole, the connection between the shift block 222 and the conductive member 221 is insulated, and a through groove adapted to the push rod 223 is provided in the button housing 23. The push rod 223 is located in the through groove in the button housing 23 and can move relative to the through groove to press the shift block 222 or release the pressing of the shift block 222.

[0051] It should be noted that the number of the conductive protrusions 2211 corresponding to one of the shift blocks 222 is two, and the shift block 222 is a conductor setting. When the shift block 222 presses the two corresponding conductive protrusions 2211 and abuts against the second connecting part 21, the shift block 222 is connected to the first connecting part 121 through the second connecting part 21 and the conductive protrusion 2211, and the first connecting part 121 generates an electrical signal representing the function of the button assembly 20 and sends it to the controller, that is, the shift block 222 is related to the function of the button assembly 20, and when different shift blocks 222 are connected to the first connecting part 121, the first connecting part 121 generates electrical signals representing different functions and sends them to the controller.

[0052] For example, the button assembly 20 is provided with a shift block 222 with a resistance of 300Ω, and the function adapted thereto is volume reduction. Then, the function corresponding to the pressing conductive part in the button assembly 20 is volume reduction, and the function corresponding to the button assembly 20 is also volume reduction.

[0053] In this embodiment, the button conductive part 22 includes the top rod 223 for applying pressing force to the shift block 222, and also includes the conductor part for moving with the shift block 222 and assisting the shift block 222 to conduct the first connection part 121, so that the button conductive part 22 has the function of conducting the first connection part 121, and also has an automatic rebound function to avoid the first connection part 121 from being continuously conducted when there is no external pressing force, so that the first connection part 121 continues to send a control signal to the controller, which is beneficial to the stability and practicality of the switch assembly.

[0054] Based on the above embodiment, the key conductive portion 22 may be further defined as follows:

[0055] In some embodiments, the button conductive portion 22 includes two or more blocking blocks 222 and a push rod 223 , and the conductive protrusion 2211 on the conductive member 221 is provided corresponding to the blocking blocks 222 .

[0056] Specifically, the shift block 222 is related to the electrical signal generated by the first connecting portion 121, and the button conductive portion 22 is provided with two or more shift blocks 222, that is, the button assembly 20 has two or more functions, which is conducive to the minimalist setting of the switch assembly and simplifies the user's operation of the switch assembly.

[0057] A shift block 222 corresponds to two of the conductive protrusions 2211 and a push rod 223. A gold-plated disk is provided on the side of the second circuit board 24 close to the conductive part 221. The gold-plated disk is connected to the second connecting part 21 and is arranged over a large area on the second circuit board 24. This can ensure that the multiple conductive protrusions 2211 on the conductive part 221 can all abut against the gold-plated disk, and then abut against the second connecting part 21, which is beneficial to the operating stability of the button assembly 20, and further beneficial to the operating stability of the switch assembly.

[0058] Exemplarily, the function corresponding to the button assembly 20 is volume adjustment. The button assembly 20 is provided with a shift block 222 with a resistance of 300Ω and a shift block 222 with a resistance of 400Ω. The function adapted to the 300Ω resistor is volume reduction, and the function adapted to the 400Ω resistor is volume increase. The pressing conductive part in the button assembly 20 has two functions, that is, the button assembly 20 has two functions. When the shift block 222 with a resistance of 300Ω is pressed to connect the first connecting part 121, the function executed by the controller is volume reduction. When the shift block 222 with a resistance of 400Ω is pressed to connect the first connecting part 121, the function executed by the controller is volume increase.

[0059] In some embodiments, as Figure 1 and Figure 2 As shown, the button assembly 20 further includes a button body 25 , which is protruding relative to the switch housing 11 and elastically connected to the button housing 23 to apply pressure to or release pressure on the push rod 223 .

[0060] Specifically, the button body 25 is used for the user to press. Under the action of the user's pressing force, the button body 25 presses the top rod 223, thereby causing the shift block 222 to press the conductive protrusion 2211 on the conductive member 221 to abut against the second connecting part 21. The shift block 222 conducts the first connecting part 121, and the button body 25 is the input end of the button assembly 20.

[0061] The button body 25 is elastically connected to the button housing 23 , which is convenient for the user to press the button body 25 . When the pressing is released, the button body 25 automatically resets, thereby ensuring the stable operation of the button assembly 20 .

[0062] In addition, the button body 25 is protruding relative to the switch housing 11, which can facilitate the user to operate the button body 25 and improve the practicality of the switch assembly.

[0063] Illustratively, the button body 25 is rotatably connected to the button shell 23, and a reset spring is provided at the connection. When the user presses the button body 25, the button body 25 presses the push rod 223, the shift block 222 and the conductive protrusion 2211 in sequence. When the user releases the pressure, the button body 25 is automatically reset to a state in which it has no effect on the push rod 223 under the action of the reset spring.

[0064] For another example, when the button assembly 20 has two functions, that is, the button assembly 20 includes two shift blocks 222, the top rod 223 also has two and is respectively arranged corresponding to the two shift blocks 222. The middle part of the button body 25 is rotatably connected to the middle part of the button shell 23. When the user presses the top of the button body 25, one top rod 223 presses one shift block 222, and the controller performs a functional operation. When the user presses the bottom of the button body 25, the other top rod 223 presses the other shift block 222, and the controller performs another functional operation.

[0065] In some embodiments, as Figure 2 and Figure 3 As shown, the key assembly 20 further includes a key panel 26 , which is covered on the periphery of the key housing 23 and is detachably connected to the key housing 23 , and is provided with a through hole for the key body 25 to pass through.

[0066] Specifically, the key panel 26 is used to cover the key housing 23 to protect the key housing 23 and prevent external debris from entering the key housing 23 to affect the normal use of the second circuit board 24 or the key conductive part 22, thereby facilitating the stable operation of the key assembly 20.

[0067] It should be noted that the outer surface of the key panel 26 is set at the same height as the outer surface of the switch housing 11, and the key body 25 passes through the through hole on the key panel 26 to protrude relative to the switch housing 11, which is not only beneficial to the appearance of the switch assembly, but also convenient for users to operate the key component 20.

[0068] The button panel 26 is provided with a beacon of the function corresponding to the corresponding shift block 222 to remind the user that the button assembly 20 can realize the corresponding function, so as to facilitate the user to operate the button assembly 20 .

[0069] In some embodiments, as Figure 1 As shown, a plurality of key slots 113 are provided in the switch housing 11 , and a key assembly 20 is provided in each key slot 113 , and the key assembly 20 is detachably connected to the key slot 113 ;

[0070] A plurality of first connecting portions 121 are defined on the first circuit board 12 , and each of the key components 20 corresponds to one of the first connecting portions 121 .

[0071] Specifically, the switch housing 11 is provided with a plurality of key slots 113, the key assembly 20 is adapted to the key slots 113 and is located in the key slots 113, the key body 25 of the key assembly 20 protrudes from the key slots 113, and the key assembly 20 is detachably connected to the switch housing 11 through the key slots 113, and each key slot 113 corresponds to a first connecting portion 121, so that the key assembly 20 in each key slot 113 is connected to the first connecting portion 121.

[0072] In this embodiment, the switch assembly includes a plurality of key slots 113 for connecting the key assemblies 20, so that the switch assembly has a switch with multiple functions, which is beneficial to the integration of the switch. At the same time, the relatively independent arrangement of the plurality of key assemblies 20 makes it unnecessary to replace the switch assembly when one of the key assemblies 20 is damaged, and only the damaged key assembly 20 needs to be replaced. Moreover, the function of the key assembly 20 is independent of its position. The user can adjust the position of the plurality of key assemblies 20 on the switch housing 11 as needed, thereby improving the practicality and flexibility of the switch assembly and reducing the development and maintenance costs of the switch assembly.

[0073] In some embodiments, as Figure 2 As shown, the switch housing 11 includes a detachably connected switch base 111 and a switch shell 112, the first circuit board 12 is located between the switch base 111 and the switch shell 112, the key slot 113 is located on the switch shell 112, and the first circuit board 12 is detachably connected to the outer bottom of the key slot 113.

[0074] Specifically, the switch base 111 is used to connect to the vehicle, and the first circuit board 12 is located between the switch base 111 and the switch housing 112, which facilitates the connection between the first connecting portion 121 on the first circuit board 12 and the second connecting portion 21 of the button assembly 20 located on the switch housing 112, and also facilitates the connection between the first connecting portion 121 and the controller through the base, thereby simplifying the wiring layout of the switch assembly.

[0075] The first circuit board 12 is detachably connected to the bottom of the key slot 113 , which facilitates replacement of the first circuit board 12 when the first circuit board 12 fails, thereby reducing maintenance costs of the switch assembly.

[0076] Exemplarily, the first circuit board 12 and the key slot 113 are detachably connected via bolts 13 .

[0077] In some embodiments, as Figure 4 As shown, a bidirectional connection terminal 1131 is provided at the bottom of the key slot 113 , and the first connection portion 121 and the second connection portion 21 are respectively connected to two ends of the bidirectional connection terminal 1131 .

[0078] Specifically, the bidirectional connection terminal 1131 is used to connect the first connection part 121 and the second connection part 21, which can not only ensure the stable connection between the first connection part 121 and the second connection part 21, which is beneficial to the stability of the switch assembly, but also does not affect the detachable connection between the button assembly 20 and the button slot 113, thereby improving the practicality of the switch assembly.

[0079] Exemplarily, the bidirectional connection terminal 1131 is a copper ring, which is embedded in the bottom of the key slot 113 , with one end located inside the key slot 113 and abutting against the second connection portion 21 , and the other end located outside the key slot 113 and abutting against the first connection portion 121 .

[0080] In some embodiments, as Figure 4 As shown, the button assembly 20 is magnetically connected to the switch housing 11 .

[0081] Specifically, a first magnetic structure 1132 is provided on the side of the switch housing 11 close to the button assembly 20, and a second magnetic structure 2311 corresponding to the first magnetic structure 1132 is provided on the side of the button assembly 20 close to the switch housing 11. When the button assembly 20 is located in the switch housing 11, the first magnetic structure 1132 is magnetically connected to the second magnetic structure 2311, thereby magnetically connecting the button assembly 20 to the switch housing 11.

[0082] In this embodiment, the button assembly 20 is magnetically connected to the switch housing 11, which not only simplifies the connection between the button assembly 20 and the switch housing 11, but also reduces the connection cost between the button assembly 20 and the switch housing 11, which is beneficial to the practicality of the switch assembly.

[0083] It should be noted that the button assembly 20 is located in the button slot 113 on the switch housing 11. In order to facilitate the removal and installation of the button assembly 20, two first magnetic structures 1132 are set at the bottom of the button slot 113, and two second magnetic structures 2311 corresponding to the first magnetic structures 1132 are set on the side of the button assembly 20 close to the bottom of the button slot 113.

[0084] Based on the above description, the structure of the first circuit board 12 is specifically described as follows: Figure 5 As shown, the first circuit board 12 includes a variety of electronic components. The first connecting part 121 is two connecting points below K1, K2, K3 and K4 in the figure. One first connecting part 121 corresponds to two connecting points. Four first connecting parts 121 are exemplarily marked in the figure. Each first connecting part 121 is connected to one of the button components 20, and there is only one shift block 222 in the button component 20.

[0085] When the user presses the button body 25, the button body 25 drives the push rod 223 to move downward, the push rod 223 presses the stop block 222, and the stop block 222 presses the conductive protrusion 2211 to move downward. The conductive particles on the conductive protrusion 2211 contact the gold-plated plate on the second circuit board 24, and then contact the second connecting portion 21 on the second circuit board 24, and the first connecting portion 121 connected to the second connecting portion 21 is conductive. Figure 5As shown, K1, K2, K3 and K4 correspond to four key components 20, and the resistance values ​​R1, R2, R3 and R4 in the four key components 20 are all different. The MCU identifies the voltage change of the I / O port and determines whether the key corresponding to the resistor is pressed. If the key is not pressed, the I / O port voltage of K1 is VCC voltage (usually 5V). When K1 is pressed and connected, due to the connection of resistor R1, the voltage of the I / O port of K1 will change. The MCU can recognize the corresponding voltage change and determine that K1 is turned on. At the same time, the function corresponding to K1 is transmitted to the controller through the LIN signal, and the controller controls the corresponding function to be turned on.
