Description

Technical Field

[0001] The present application relates to the technical field of vehicle components, and more specifically to a combination switch, and also to a vehicle including the combination switch. Background Art

[0002] The clock spring is a device installed in the combination switch that connects the airbag, multi-function buttons, horn, and other features on the steering wheel to the vehicle's controls. It's suitable for multi-function steering wheels, integrating more functions to meet the needs of high-end vehicles. The horn push rod is a device installed in the combination switch that connects the horn to the vehicle's controls. It's suitable for non-multi-function steering wheels that don't require airbags or multi-function buttons. It doesn't require a wide range of features and can meet the needs of certain types of vehicles and situations.

[0003] Currently, there are two types of combination switches available on the market: one with a single function, equipped with a clock spring, for use with multi-function steering wheels; and another with a single function, equipped with a horn push rod mechanism, for use with vehicles without multi-function steering wheels. Using a combination switch with a clock spring for a vehicle without a multi-function steering wheel results in unnecessary cost; while using a combination switch without a clock spring and equipped with only a horn push rod for a multi-function steering wheel fails to achieve multi-functionality. As can be seen from the above, the function of a single combination switch is fixed and cannot be flexibly changed, making it suitable only for specific vehicle models. Utility Model Content

[0065] The present application provides a combination switch and also provides a vehicle including the combination switch.

[0066] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0067] like Figure 1-11 As shown, the present invention discloses a combination switch comprising a mounting body 1, a clock spring 2, and a speaker push rod mechanism 3. The mounting body 1 includes a first mounting area 11 and a second mounting area 12. The clock spring 2 is removably mounted in the first mounting area 11. The speaker push rod mechanism 3 is removably mounted in the second mounting area 12. When the combination switch is used with a multi-function steering wheel, the clock spring 2 is optionally installed. When the combination switch is used without a multi-function steering wheel, the speaker push rod mechanism 3 is optionally installed.

[0068] It should be noted that please refer to the attached Figure 1 , an assembly hole is provided in the middle area of ​​the mounting body 1; the assembly hole is fitted onto a steering column coaxially connected to the steering wheel; the mounting body 1 remains fixed and does not rotate with the steering column. The first mounting area 11 is an area of ​​the mounting body 1, used to mount and fix the clock spring 2; the mounting body 1 is provided with mounting grooves, limiting portions, fixing portions and other structures adapted to the clock spring 2. The second mounting area 12 is an area of ​​the mounting body 1, and the position of the second mounting area 12 can coincide with the position of the first mounting area 11, or it can be independent of the first mounting area 11, so that the two are located at different positions of the mounting body 1; the second mounting area 12 has a mounting hole and other structures adapted to the speaker top rod mechanism 3.

[0069] Clock spring 2 consists of a fixed member and a rotating member that rotates relative to the fixed member. Clock spring 2 is located above mounting body 1 and coaxially with the mounting hole of mounting body 1. The rotating member of clock spring 2 rotates synchronously with the steering column. The fixed member of clock spring 2 is fixedly mounted to mounting body 1 and does not rotate synchronously with the steering column.

[0070] "Multi-function steering wheel" refers to a steering wheel that integrates multiple function buttons and control devices. These function buttons can directly control multiple functions of the vehicle, improving the driver's operating convenience and safety; "non-multi-function steering wheel" refers to a steering wheel that only has basic steering functions and does not integrate other function buttons and control devices.

[0071] The combination switch also reserves a first installation area 11 for detachably installing the clock spring 2 and a second installation area 12 for detachably installing the horn push rod mechanism 3, so that when the combination switch is used for a multi-function steering wheel, the horn push rod mechanism is no longer installed, and only the clock spring is installed separately; when the combination switch is used for a vehicle without a multi-function steering wheel, the clock spring 2 is no longer installed, and only the horn push rod mechanism 3 is installed; as described above, the combination switch has multiple installation functions and can be flexibly changed according to usage requirements. It can not only meet the multi-function control requirements when used for a multi-function steering wheel, but also avoid the high cost expenditure caused by being used for a vehicle without a multi-function steering wheel. It is suitable for high, medium and low-end vehicle models.

[0072] Please see the attached Figure 1-4 In certain embodiments of the present application, the clock spring 2 has a first limiting portion 21, and the first installation area 11 has a second limiting portion 111 that cooperates with the first limiting portion 21 to limit the clock spring 2 to the first installation area 11 in the installation direction.

[0073] It should be noted that the installation direction of the clock spring 2 to the installation body 1 is the first direction. Figure 2 、4 The direction indicated by the arrow in the middle; when the combination switch is assembled in the vehicle, the first direction is from top to bottom.

[0074] For further explanation, please refer to the attached Figure 2 The clock spring 2 includes a clock spring body 26; a first limiting portion 21 is fixed to the clock spring body 26. The first limiting portion 21 can be a structure integrally connected to the clock spring body 26, or a separate structure independent of the clock spring body 26.

[0075] Please see the attached Figure 3-4 By providing the first limiting portion 21 and the second limiting portion 111 that cooperate with each other in limiting, it can be determined whether the clock spring 2 is installed in place along the first direction. When the first limiting portion 21 is limited by the second limiting portion 111 and cannot continue to move in the first direction, it is proved that the clock spring 2 has been installed in place. As described above, in the first direction, the precise positioning effect of the clock spring 2 on the first installation area 11 is guaranteed, thereby enabling the clock spring 2 to be accurately and reliably fixed in the first installation area 11, increasing the accuracy and convenience of operation and improving assembly efficiency.

[0076] Please see the attached Figure 1-4 In some embodiments, the clock spring 2 has a third limiting portion 22, and the first installation area 11 has a fourth limiting portion 112 that cooperates with the third limiting portion 22 to limit the clock spring 2 in the first installation area 11 along the circumference of the clock spring 2.

[0077] It should be noted that the third limiting portion 22 and the fourth limiting portion 112 do not restrict the displacement of the clock spring 2 along the first direction. When the clock spring 2 is installed in place along the first direction, the third limiting portion 22 is precisely limited by the fourth limiting portion 112. The circumferential direction of the clock spring 2 is perpendicular to the first direction.

[0078] It should be further explained that the third limiting portion 22 is fixed to the clock spring body 26 . The third limiting portion 22 can be a structure integrally connected to the clock spring body 26 , or a separate structure independent of the clock spring body 26 .

[0079] “Confining the clock spring 2 to the first mounting area 11 along the circumferential direction of the clock spring 2 ” means that, within a cross section perpendicular to the first direction (i.e., a cross section parallel to the circumferential direction of the clock spring 2 ), the clock spring 2 cannot move relative to the first mounting area 11 or rotate along its own circumferential direction.

[0080] By providing the third limiting portion 22 and the fourth limiting portion 112 that cooperate with each other, the clock spring 2 cannot be displaced, moved, or rotated relative to the first installation area 11, thereby ensuring that the clock spring 2 is limited to a predetermined position. As described above, the precise positioning of the clock spring 2 on the first installation area 11 is ensured in the circumferential direction of the clock spring 2, further enabling the clock spring 2 to be accurately and reliably fixedly installed in the first installation area 11, further increasing the accuracy and convenience of operation and improving assembly efficiency.

[0081] Please see the attached Figure 1-4 In some embodiments, the clock spring 2 has a first fixing portion 23 , and the first installation area 11 has a second fixing portion 113 adapted to be installed with the first fixing portion 23 , so that the clock spring 2 is fixed to the first installation area 11 .

[0082] It should be noted that when the clock spring 2 is not fully installed along the first direction, the first fixing portion 23 and the second fixing portion 113 will not restrict the displacement of the clock spring 2 along the first direction; when the clock spring 2 is fully installed along the first direction, the first fixing portion 23 can be synchronously adapted and installed on the second fixing portion 113; or, in a sequential order, after the clock spring 2 is fully installed along the first direction, the first fixing portion 23 can be adapted and installed on the second fixing portion 113.

[0083] It should be further explained that the first fixing portion 23 is fixed to the clock spring body 26 . The first fixing portion 23 may be a structure integrally connected to the clock spring body 26 , or a separate structure independent of the clock spring body 26 .

[0084] By providing the first fixing portion 23 and the second fixing portion 113 that are adapted to be installed, the clock spring 2 is securely fixed to the first installation area 11, and the freedom of the clock spring 2 in all directions relative to the first installation area 11 is constrained, thereby ensuring the reliability and safety of the combination switch during use.

[0085] It should be further explained that force may be applied directly to the first fixing portion 23 and / or the second fixing portion 113 or with the assistance of a tool, so as to release the first fixing portion 23 from the fixed connection with the second fixing portion 113 .

[0086] When the clock spring 2 needs to be installed on the mounting body 1, the clock spring 2 is moved in the first direction until the first limiting portion 21 is limited by the second limiting portion 111, so that the clock spring 2 cannot move further in the first direction; at the same time, the third limiting portion 22 is coincidentally limited and matched with the fourth limiting portion 112; and the first fixing portion 23 is fixedly mounted on the second fixing portion 113.

[0087] When the clock spring 2 needs to be removed from the mounting body 1 , the first fixing portion 23 is first separated from the second fixing portion 113 , and then the clock spring 2 is moved in the opposite direction of the first direction to separate the first limiting portion 21 from the second limiting portion 111 and the third limiting portion 22 from the fourth limiting portion 112 .

[0088] In some embodiments of the present application, the installation direction of the clock spring 2 to the installation body 1 is the first direction, that is, the first direction is attached. Figure 2 、 4 Direction indicated by the arrow.

[0089] Please see the attached Figure 1-4 The first limiting portion 21 is an abutting column having an extended length along the first direction, and the second limiting portion 111 is an abutting surface perpendicular to the first direction.

[0090] It should be noted that the surface of the abutting column close to the abutting surface is a limiting surface, and the limiting surface of the abutting column can abut against the abutting surface; the limiting surface and the abutting surface are both planes.

[0091] Furthermore, an abutment post is fixed to the surface of the clock spring body 26 near the first mounting area 11. A single abutment post may be provided, or multiple abutment posts may be provided spaced apart along the circumference of the clock spring 2. Preferably, multiple abutment posts are provided evenly spaced along the circumference of the clock spring 2; this further ensures precise positioning of the clock spring 2 on the first mounting area 11.

[0092] Setting the first limiting portion 21 as a limiting column and the second limiting portion 111 as an abutting surface formed in the first installation area 11 can not only ensure the abutting limitation of the two along the first direction, but also has a simple structure, is easy to produce and process, and saves processing and manufacturing costs.

[0093] In some other embodiments of the present application, the first limiting portion 21 is configured as an abutment surface, and the abutment surface is formed on a side surface of the clock spring body 26 close to the first mounting area 11; the second limiting portion 111 is configured as an abutment column connected to the first mounting area 11 and having an extended length in the opposite direction of the first direction.

[0094] Please see the attached Figure 1-4 In some embodiments, in a cross section perpendicular to the first direction, the third limiting portion 22 is a limiting protrusion extending from the circumferential edge of the clock spring 2, and the fourth limiting portion 112 is a limiting groove.

[0095] It should be noted that the limiting groove is arranged on the side surface of the first installation area 11 close to the clock spring body 26; the limiting groove has a hollow space along the first direction, and the side of the limiting groove close to the limiting protrusion is connected with the above-mentioned hollow space.

[0096] Furthermore, a plurality of limiting protrusions are provided at intervals along the circumference of the clock spring 2. Preferably, two limiting protrusions are provided symmetrically and at intervals along the circumference of the clock spring 2. As described above, the number of limiting protrusions provided can be minimized, while effectively ensuring the limiting effect of the clock spring 2 on the first mounting area 11 along the circumference of the clock spring 2.

[0097] As described above, the third limiting portion 22 is configured as a limiting protrusion and the fourth limiting portion 112 is configured as a limiting groove, which not only ensures that the two are abutted and limited along the circumference of the clock spring 2, but also has a simple structure, is easy to produce and process, and saves processing and manufacturing costs.

[0098] In some other embodiments of the present application, the third limiting portion 22 is configured as a limiting groove that is recessed inward relative to the circumferential edge of the clock spring 2, and the fourth limiting portion 112 is configured as a limiting protrusion, which is arranged on the surface of the first installation area 11 close to the clock spring body 26.

[0099] Please see the attached Figure 1-4 In some embodiments, the first fixing portion 23 is a snap buckle having an extended length along the first direction, and the second fixing portion 113 is a snap groove.

[0100] Optionally, the snap-fit ​​buckle is provided on the circumferential edge of the clock spring body 26; Figure 2 Along the first direction, the snap fastener includes an integrally connected extension section 231 and a snap fastener body 232. The snap fastener body 232 is located at the end of the snap fastener away from the clock spring body 26. A snap fastener groove is provided on the circumferential side wall of the first mounting area 11. The snap fastener groove has an inverted U-shaped structure. The snap fastener body 232 can be fixedly engaged with the bottom wall of the U-shaped structure to achieve snap-fastening of the first fixing portion 23 to the second fixing portion 113.

[0101] It should be noted that the extension section 231 of the snap buckle can undergo a certain elastic deformation, so that the extension section 231 bends outward or inward along the circumferential edge of the clock spring body 26, and then the extension section 231 drives the snap buckle body 232 to move to release the fixed engagement with the snap slot or to snap and fix it in the snap slot.

[0102] As mentioned above, the first fixing part 23 is set as a snap buckle and the second fixing part 113 is set as a snap groove, which not only realizes the convenient and fast detachable installation of the two, but also ensures the firmness and stability of the installation and fixation of the two; its structure is simple, easy to produce and process, and saves processing and manufacturing costs.

[0103] In some other embodiments of the present application, the first fixing portion 23 is configured as a first mounting ear plate extending outward from the circumferential edge of the clock spring body 26, and the second fixing portion 113 is configured as a second mounting ear plate extending outward from the circumferential side wall of the first mounting area 11. Fasteners are sequentially passed through the assembly holes of the first mounting ear plate and the assembly holes of the second mounting ear plate to achieve adaptive installation of the first fixing portion 23 and the second fixing portion 113, thereby completing the detachable installation and fixation of the two.

[0104] Of course, the first fixing portion 23 and the second fixing portion 113 may also be other structural arrangements, which will not be described in detail here. It is sufficient to ensure that the clock spring 2 can be reliably and detachably fixed to the first installation area 11 .

[0105] In some embodiments of this application, please refer to the attached Figure 1 The second mounting area 12 is provided with a through mounting hole 121; Figure 9 A first restraining portion 122 is formed inside the mounting hole 121. Figure 5-9 The speaker push rod mechanism 3 includes a speaker push rod body 31, a reset member 32, and a stop member 33. The speaker push rod body 31 is movably inserted into the mounting hole 121 and is formed with a second restraining portion 311. The bottom of the reset member 32 is fixedly restrained by the first restraining portion 122, and the top of the reset member 32 is movable and restrained by the second restraining portion 311. The stop member 33 is provided on the speaker push rod body 31 and can limit the upward movement of the second restraining portion 311 to the limit position. When the second restraining portion 311 is in the limit position, the reset member 32 is in a compressed state or a natural state.

[0106] Optionally, when the combination switch is installed in a vehicle, the axis of mounting hole 121 is oriented along the vehicle's height. When downward pressure is applied to horn top rod body 31, horn top rod body 31 moves downward, triggering a microswitch connected to the alarm horn, thereby causing the alarm horn to sound an alarm. Furthermore, a wiring harness 34 is connected to the bottom of horn top rod body 31 to transmit the electrical signal generated by the microswitch to the vehicle controller, which then controls the alarm horn to sound an alarm.

[0107] The “limit position” to which the second restraining portion 311 moves upward is a position where the second restraining portion 311 can remain stationary when no pressing force is applied.

[0108] Please see the attached Figure 9, the first constraint portion 122 remains fixed in position, and the second constraint portion 311 can move along the axis of the mounting hole 121. Under the action of the downward pressing force, the second constraint portion 311 moves downward, driving the reset member 32 to compress and move in the direction close to the first constraint portion 122. When the pressing force is released, the reset member 32 has an upward elastic force to restore its own deformation, and the reset member 32 drives the second constraint portion 311 to move upward. The upward movement of the second constraint portion 311 drives the speaker top rod body 31 to move upward, and the upward movement of the speaker top rod body 31 drives the stop member 33 to move upward; until the stop member 33 moves upward to the stop position, at which time, under the limiting action of the stop member 33, the speaker top rod body 31 stops moving upward, and the second constraint portion 311 is limited to the extreme position of upward movement, completing the automatic reset of the speaker top rod body 31.

[0109] Furthermore, when the second restraining portion 311 is in its extreme position, the restoring member 32 is in a compressed state or a natural state. As described above, without applying any external force, the second restraining portion 311 is ensured to automatically return upwards due to the elastic force of the restoring member 32 restoring its own deformation. Preferably, when the second restraining portion 311 is in its extreme position, the restoring member 32 is in a compressed state.

[0110] It should be noted that the speaker top rod body 31 can be internally sleeved within the reset member 32, or it can be not internally sleeved within the reset member 32. Preferably, the speaker top rod body 31 is internally sleeved within the reset member 32; the first constraint portion 122 is a circular ring-shaped structure fixed to the circumferential inner wall of the mounting hole 121, and the speaker top rod body 31 is movably internally sleeved within the center hole of the above-mentioned circular ring-shaped structure. The outer diameter of the above-mentioned circular ring-shaped structure is larger than the outer diameter of the reset member 32 to provide a constraint position for the bottom of the reset member 32; the speaker top rod body 31 includes a sleeve section that is internally sleeved within the reset member 32, and the outer diameter of the second constraint portion 311 is larger than the outer diameter of the sleeve section of the reset member 32 to form a step surface at the connection between the two. The outer diameter of the above-mentioned step surface is larger than the outer diameter of the reset member 32 to provide a constraint position for the top of the reset member 32.

[0111] The reset member 32 can be any of a spring, bellows, or elastic rubber. The reset member 32 is not fixedly connected to the first or second restraining portion 122, 311; it is simply positioned between them and, under the action of its own elastic force, abuts and constrains them there. The first restraining portion 122 is formed at the bottom of the mounting hole 121. The second restraining portion 311 is capable of reciprocating within the mounting hole 121, but will not move outside of the mounting hole 121.

[0112] Please see the attached Figure 5 、 9In some embodiments of the present application, the stopper 33 is located at the bottom of the mounting hole 121, and the outer diameter of the stopper 33 is larger than the inner diameter of the mounting hole 121. The speaker top rod body 31 is formed with a stopper groove 312 along its circumference. The stopper 33 is detachably mounted in the stopper groove 312.

[0113] As described above, the second mounting area 12 is formed with a circumferential wall surrounding the mounting hole 121 , and the bottom of the circumferential wall forms a stop position for limiting the upward movement of the stop member 33 , which has a simple structure and is easy to produce and process.

[0114] When the speaker top rod mechanism 3 needs to be installed in the second installation area 12 , the reset member 32 is first placed in the installation hole 121 , and then the speaker top rod body 31 is inserted into the reset member 32 , and finally the stop member 33 is snap-fitted and fixed in the stop groove 312 .

[0115] When the speaker top rod mechanism 3 needs to be disassembled to disengage from the second mounting area 12, the stopper 33 is first disassembled to disengage from the stop groove 312, and then the speaker top rod body 31 is removed from the top opening of the mounting hole 121, and finally the reset member 32 is removed from the top opening of the mounting hole 121.

[0116] Furthermore, the stopper 33 may be a retaining spring, which is an elastic member that can be securely and stably fixed in the retaining groove 312 .

[0117] Please see the attached Figure 2 、 10 -11. In certain embodiments of the present application, the combination switch includes a rotation angle sensor 4 , which is coaxially and detachably mounted on the bottom of the clock spring 2 to detect the rotation angle and direction of the clock spring 2 .

[0118] It should be noted that when used without a multifunction steering wheel, the angle sensor 4, along with the clock spring 2, is removed from the mounting body 1. "Coaxial" means that the angle sensor 4 is coaxial with the rotating element of the clock spring 2 and with the steering column. When the combination switch is installed in the vehicle, the angle sensor 4 is located above the mounting body 1, between the clock spring 2 and the mounting body 1. Rotation of the multifunction steering wheel rotates the steering column, which in turn rotates the rotating element of the clock spring 2. At this point, the rotating element of the clock spring 2 rotates relative to the angle sensor 4. Therefore, the rotation angle and direction data measured by the angle sensor are the same as those of the multifunction steering wheel.

[0119] The steering angle sensor 4 is used to measure the rotation angle and direction of the multi-function steering wheel in real time to provide accurate rotation angle and direction data for at least one of the electric power steering (EPS) system, stability control system (ESC), lane keeping assist system (LKA), driver assistance system, etc., to achieve multi-functional integration of high-configuration models.

[0120] Please see the attached Figure 2 、 10 -11. In certain embodiments of the present application, the rotation angle sensor 4 has a fifth limiting portion 41 , and the clock spring 2 has a sixth limiting portion 24 that cooperates with the fifth limiting portion 41 to limit the rotation angle sensor 4 to the clock spring 2 .

[0121] It should be noted that the installation direction of the rotation angle sensor 4 toward the clock spring 2 is the second direction. Figure 11 The direction indicated by the arrow in the middle; when the combination switch is assembled in the vehicle, the second direction is from bottom to top.

[0122] It should be further explained that the rotation angle sensor 4 includes a rotation angle sensor body 43, to which the fifth stopper 41 is fixed. The fifth stopper 41 may be integrally connected to the rotation angle sensor body 43 or a separate structure independent of the rotation angle sensor body 43. The clock spring 2 includes a clock spring body 26, to which the sixth stopper 24 is fixed. The sixth stopper 24 may be integrally connected to the clock spring body 26 or a separate structure independent of the clock spring body 26.

[0123] By providing the fifth limiting portion 41 and the sixth limiting portion 24 that cooperate with each other, the rotation angle sensor 4 and the clock spring 2 can be accurately positioned to ensure that the rotation angle sensor 4 is limited to a predetermined position. As described above, it is ensured that the rotation angle sensor 4 can be accurately and reliably fixed on the clock spring 2, thereby increasing the accuracy and convenience of operation and improving assembly efficiency.

[0124] Please see the attached Figure 2 、 10 -11. In some embodiments, the rotation angle sensor 4 has a third fixing portion 42 , and the clock spring 2 has a fourth fixing portion 25 adapted to be mounted on the third fixing portion 42 , so that the rotation angle sensor 4 is fixed to the clock spring 2 .

[0125] It should be noted that when the rotation angle sensor 4 is not installed in place along the second direction, the third fixing portion 42 and the fourth fixing portion 25 will not restrict the displacement of the rotation angle sensor 4 in the second direction; when the clock spring 2 is installed in place along the second direction, the third fixing portion 42 can be synchronously adapted and installed on the fourth fixing portion 25; or, in a sequential order, after the rotation angle sensor 4 is installed in place along the second direction, the third fixing portion 42 can be adapted and installed on the fourth fixing portion 25.

[0126] By providing the third fixing portion 42 and the fourth fixing portion 25 that are adapted to be installed, the rotation angle sensor 4 is firmly fixed to the clock spring 2, and the freedom of the rotation angle sensor 4 in all directions relative to the clock spring 2 is constrained, thereby ensuring the reliability and safety of the combination switch during use.

[0127] It should be noted that when the rotation angle sensor 4 needs to be installed on the clock spring 2, the rotation angle sensor 4 is moved along the second direction until the fifth limiting portion 41 is guided and limited to the sixth limiting portion 24; and the third fixing portion 42 is fixedly installed on the fourth fixing portion 25.

[0128] When the rotation angle sensor 4 needs to be disassembled and separated from the clock spring 2, the third fixing portion 42 is first separated from the fixed installation with the fourth fixing portion 25, and then the rotation angle sensor 4 is moved in the opposite direction of the second direction to separate the fifth limiting portion 41 from the sixth limiting portion 24.

[0129] In some embodiments of the present application, the direction in which the rotation angle sensor 4 is installed toward the clock spring 2 is the second direction. Figure 11 Direction indicated by the arrow. Figure 2 、 10 -11, the fifth limiting portion 41 is a limiting hole extending along the second direction, and the sixth limiting portion 24 is a limiting pin extending along the second direction.

[0130] Optionally, a limiting hole is provided on the circumferential edge of the rotation angle sensor body 43, and in a cross section perpendicular to the second direction, the limiting hole extends beyond the circumferential edge of the rotation angle sensor body 43; the axis of the limiting hole is parallel to the second direction. A limiting pin is provided on the surface of the clock spring body 26 near the rotation angle sensor body 43; when the rotation angle sensor 4 moves in the second direction, the limiting pin limits and guides movement along the limiting hole.

[0131] Furthermore, a plurality of limiting holes are provided at intervals along the circumference of the rotation angle sensor 4. Preferably, two limiting holes are provided symmetrically and at intervals along the circumference of the rotation angle sensor 4. This minimizes the number of limiting holes and effectively ensures the limiting effect of the rotation angle sensor 4 on the clock spring 2 along the circumference of the rotation angle sensor 4.

[0132] Correspondingly, two limit pins are provided, one of which serves as a reference position and the other as an adjustment position. The two are used in conjunction with each other to improve the assembly accuracy of the angle sensor 4 on the clock spring 2, reduce assembly errors, and improve adaptability.

[0133] As described above, the fifth limiting portion 41 is set as a limiting hole and the sixth limiting portion 24 is set as a limiting pin, which ensures the abutment and limiting of the two along the circumference of the rotation angle sensor 4. In addition, its structure is simple, easy to produce and process, and saves processing and manufacturing costs.

[0134] In some other embodiments of the present application, the fifth limiting portion 41 is configured as a limiting pin, and the sixth limiting portion 24 is configured as a limiting hole.

[0135] Please see the attached Figure 2 、 10 -11. In some embodiments of the present application, in a cross section perpendicular to the second direction, the third fixing portion 42 is a hook that can extend out of or retract the circumferential edge of the rotation angle sensor 4, and the fourth fixing portion 25 is a hanging hole.

[0136] It should be noted that the hook is provided on the circumferential side wall of the rotation angle sensor body 43. The hook hole is formed by a through-hole formed in the hook member and extends along the second direction. The hook hole is formed on the side of the clock spring body 26 adjacent to the rotation angle sensor body 43. Furthermore, multiple hooks are provided at intervals along the circumference of the rotation angle sensor body 43, and multiple hook holes are provided at intervals along the circumference of the clock spring body 26 to correspond to each hook.

[0137] When the rotation angle sensor 4 moves along the second direction, the hook is gradually retracted into the rotation angle sensor body 43 under the abutment of the hanging hole, so that the movement of the rotation angle sensor 4 along the second direction is not restricted; until the rotation angle sensor 4 is installed in place along the second direction, the hook is relative to the hanging hole, and the hook is no longer subject to any restraining force and extends relative to the circumferential edge of the rotation angle sensor body 43 and extends into the hanging hole, thereby realizing the hooking and fixation of the hook on the hanging hole, and further realizing the hooking and fixation of the angle sensor 4 on the clock spring 2.

[0138] As mentioned above, the third fixing part 42 is set as a hook and the fourth fixing part 25 is set as a hanging hole, which not only realizes the convenient and fast detachable installation of the two, but also ensures the firmness and stability of the hanging and fixing of the two; its structure is simple, easy to produce and process, and saves processing and manufacturing costs.

[0139] When the rotation angle sensor 4 needs to be installed on the clock spring 2, the rotation angle sensor 4 is moved along the second direction. At this time, the limiting hole moves along the limiting pin guide; at the same time, the hanging buckle extends into the hanging hole.

[0140] When the rotation angle sensor 4 needs to be disassembled and separated from the clock spring 2, first press the hook to disengage the hook from the hanging hole and retract it into the rotation angle sensor body 43 to avoid interfering with the movement of the rotation angle sensor 4 along the second direction. Then, move the rotation angle sensor 4 in the opposite direction of the second direction to disengage the limit pin from the limit hole.

[0141] Please see the attached Figure 1 In certain embodiments of the present application, the combination switch includes a hand-shift switch 5, a light switch 6, and a wiper switch 7. The hand-shift switch 5 is mounted on a first handle on a first side of the mounting body 1 and is used to provide an electronic shift function. The light switch 6 and the wiper switch 7 are both mounted on a second handle on a second side of the mounting body 1 to provide light control functions and wiper control functions, respectively.

[0142] It should be noted that the attached Figure 1 Only one exemplary arrangement of the handgrip switch 5, the light switch 6, and the wiper switch 7 on the mounting body 1 is shown; in other embodiments, the handgrip switch 5 may also be arranged on the second handle, while the light switch 6 and the wiper switch 7 are arranged on the first handle; the light switch 6 may be closer to the mounting body 1 relative to the wiper switch 7; or the light switch 6 may be farther away from the mounting body 1 relative to the wiper switch 7.

[0143] As described above, the integrated assembly of the armrest switch 5 and the mounting body 1 is realized, and the armrest switch 5 is no longer arranged on the auxiliary instrument panel between the main driver's seat and the co-driver's seat, realizing the flat-lying function of the cab along the width direction of the vehicle.

[0144] It should be noted that the shift switch 5 includes controls for R (reverse), N (neutral), D (drive), and P (park). The light switch 6 includes controls for left and right turn, low beam, high beam, low headlight, passing light, automatic headlight, rear fog light, and light off. The wiper switch 7 includes controls for wiper inching, wiper spray, intermittent wiper / automatic wiper, low wiper speed, high wiper speed, and front wiper off.

[0145] The shift switch 5, light switch 6, and wiper switch 7 are respectively connected to the vehicle controller in communication; the vehicle controller is respectively connected to each actuator, including the engine, headlights, wipers, etc.; the vehicle controller sends control instructions to each actuator through the CAN protocol. The control part of the shift switch 5 is manipulated to generate a shift electrical signal, and the vehicle controller identifies the shift electrical signal and sends a shift control instruction to the engine to achieve switching between different gears and realize the shifting function. The control part of the light switch 6 is manipulated to generate a light electrical signal, and the vehicle controller identifies the light electrical signal and sends a light control instruction to each headlight to achieve switching between different headlight modes and realize the light control function. The control part of the wiper switch 7 is manipulated to generate a wiper electrical signal, and the vehicle controller identifies the wiper electrical signal and sends a control instruction to the wiper to achieve switching between different wiper modes and realize the wiper control function.
