[0048] The technical solutions of the present application are further illustrated below in conjunction with the accompanying drawings and specific embodiments.

[0049] As Figures 1 to 11 shown, the embodiment of the present application provides a combination switch handle 100 applied in a vehicle steering wheel assembly to control the steering, high-low beam conversion, wiper and other functions of the vehicle.

[0050] The combination switch handle 100 comprises an operating member 2, a sensing member 3, a connecting housing 5, a piston 8 and a flexible circuit board 9. The operating member 2 is the main supporting structure of the combination switch handle 100, and the control function of the combination switch handle 100 can be triggered by actuating the operating member 2. The connecting housing 5 comprises a fixed part 51 and a connecting part 52 arranged at an angle, the fixed part 51 is used to be fixed with the steering wheel base 200, and the connecting part 52 is arranged in the operating member 2, the end of the operating member 2 close to the steering wheel base 200 is rotationally connected with the connecting part 52, so that the rotation of the operating member 2 relative to the steering wheel base 200 can be realized. The operating member 2 is provided with a receiving space along the length direction thereof, and a curved surface part is arranged at the end of the receiving space away from the connecting part 52. The piston 8 is movably arranged in the receiving space, one end of the piston 8 is elastically connected to the end of the receiving space close to the connecting part 52, and the other end of the piston 8 abuts against the curved surface part. In this embodiment, the piston 8 is arranged to facilitate the movement reset of the operating member 2. Specifically, when the operating member 2 is rotated under the action of external force, the curved surface part can be driven to move synchronously, and the curved surface part can drive the piston 8 to move; when the external force is removed, the piston 8 can be reset under the action of elastic force, thereby driving the operating member 2 to reset. The flexible circuit board 9 is used to connect the button switch, knob switch and other switches at the end of the handle. The flexible circuit board 9 is fixedly connected to the operating member 2, and the end of the flexible circuit board 9 is arranged to pass through the fixed part 51 to be electrically connected with the steering wheel circuit board 300. To facilitate the flexible circuit board 9 to pass through the fixed part 51, a threading groove 511 is arranged at the end of the fixed part 51 close to the connecting part 52, at least part of the flexible circuit board 9 is arranged to pass through the threading groove 511, and the part of the flexible circuit board 9 passing through the threading groove 511 is electrically connected with the steering wheel circuit board 300. The sensing member 3 is arranged at the opposite side of the piston 8, the sensing member 3 is fixedly connected with the operating member 2 through the flexible circuit board 9, and the sensing member 3 is electrically connected with the flexible circuit board 9. When the operating member 2 rotates relative to the connecting part 52, the sensing member 3 can move synchronously with the operating member 2, and the relative position change between the connecting part 52 and the sensing member 3 can be sensed; the sensing member 3 feeds back the position information to the controller, and the controller judges the movement position of the operating member 2 according to the position information to control the opening and closing of the corresponding function. Different movement positions correspond to the control of different functions of the vehicle steering, high-low beam conversion, wiper and other functions.

[0051] The combination switch handle 100 provided by the embodiment of the present application can integrate the flexible circuit board 9 and the inductor 3 for realizing the control function and the piston 8 for realizing the movement function in the handle by arranging the operating member 2 and the connecting shell 5, greatly improves the integration of the combination switch handle 100, saves the space occupied by the control components and the movement components of the combination switch in the clock spring area of the center of the steering wheel base 200, and improves the space utilization in the handle. By arranging the inductor 3 directly on the flexible circuit board 9, the additional circuit board for the inductor 3 is avoided, and the space utilization in the handle is further improved. Moreover, since the inductor 3 is fixedly connected with the operating member 2 through the flexible circuit board 9, the three are relatively static, so that the inductor 3 and the flexible circuit board 9 can move synchronously in the movement process of the combination switch handle 100, thus ensuring the connection reliability of the inductor 3 and the flexible circuit board 9, and avoiding the poor contact caused by the long-term pulling of the connection between the flexible circuit board 9 and the inductor 3. In addition, the embodiment of the present application integrates the above components in the handle, the handle forms a whole, and only the connecting shell 5 is fixed with the steering wheel base 200 during installation, and the part of the flexible circuit board 9 that is arranged outside the connecting shell 5 is electrically connected with the electronic components in the steering wheel base 200, so that the assembly of the combination switch handle 100 and the steering wheel base 200 is completed, which makes the assembly process of the combination switch handle 100 and the steering wheel base 200 simpler and more convenient, improves the assembly efficiency, and reduces the production cost.

[0052] Optionally, the operating member 2 is provided with a containing cavity 21, the containing cavity 21 forms the containing space, the connecting part 52 is arranged in the containing cavity 21, and the containing cavity 21 and the connecting part 52 have a clearance space, so that the operating member 2 can rotate smoothly relative to the connecting part 52, and the movement jamming is avoided.

[0053] Optionally, the combination switch handle 100 further comprises an abutting block 6 fixed on the operating member 2, and a curved groove 61 is arranged in the abutting block 6, and the curved groove 61 forms the curved surface part. In this embodiment, the abutting block 6 is arranged, which is beneficial to simplify the structure of the operating member 2 and facilitate the processing. In the production, the abutting block 6 and the operating member 2 can be processed respectively, and then the abutting block 6 is fixed on the operating member 2. Further, the connecting part 52 is provided with a first cavity 521, and the piston 8 is movably arranged in the first cavity 521, so that the movement of the piston 8 can be guided and limited, and the movement of the piston 8 is more accurate. The first cavity 521 is further provided with an elastic member 7, which is elastically arranged between the piston 8 and the inner wall of the first cavity 521. The front end of the piston 8 abuts against the curved groove 61, so that the elastic reset function of the piston 8 can be realized. Optionally, the elastic member 7 is a spring, which has simple structure and reliable elasticity. Specifically, the curved groove 61 is approximately hemispherical, and the depth of the center part is the deepest, and the depth of the circumferential wall is relatively shallow. When the combination switch handle 100 is not actuated, the front end of the piston 8 abuts against the center part of the curved groove 61. When the combination switch handle 100 is actuated by external force, the abutting block 6 rotates with the operating member 2, so that the front end of the piston 8 moves along the circumferential wall of the curved groove 61, and at the same time, the elastic member 7 is elastically deformed by the extrusion of the piston 8. When the external force is removed, the elastic member 7 pushes the piston 8 to reset under the action of the elastic force. Due to the abutting action of the piston 8 and the curved groove 61, the abutting block 6 is reset, and at the same time, the operating member 2 is also reset. The above arrangement has reasonable structure and reliable movement, and is beneficial to realize the automatic reset of the combination switch handle 100 after being actuated, and can reduce the error caused by manual reset.

[0054] Optionally, the sensing element 3 is specifically a Hall sensor, which is fixed to and electrically connected to the flexible circuit board 9. A magnet 4 is disposed at a position opposite to the Hall sensor on the connecting part 52. When the operating member 2 rotates relative to the connecting part 52, the Hall sensor can move synchronously with the operating member 2 and sense the change in magnetic field caused by the change in position of the magnet 4 relative to the Hall sensor. Specifically, when the combination switch handle 100 is not moved, the Hall sensor and the magnet 4 are positioned relative to each other; when the combination switch handle 100 is moved, the relative position between the Hall sensor and the magnet 4 changes, resulting in a change in the magnetic induction intensity between them. The Hall sensor can sense the change in magnetic field and feed the signal back to the controller. The controller determines the movement position of the operating member 2 based on this signal, thereby controlling the corresponding switch. This invention employs a Hall sensor and a magnet 4 in combination to achieve the sensing function. This combination provides high sensitivity and reliability, which helps extend the service life of the combination switch handle 100. Furthermore, the Hall sensor is fixed to the flexible circuit board 9. During the movement of the combination switch handle 100, the Hall sensor moves accordingly, while the magnet 4 remains fixed to the connecting part 52 and does not move. This ensures the reliable connection between the Hall sensor and the flexible circuit board 9, avoiding the problem of poor contact caused by long-term tension at the connection point between the flexible circuit board 9 and the Hall sensor due to the Hall sensor remaining stationary while the magnet 4 moves with the handle.

[0055] Furthermore, the operating member 2 is provided with a clearance notch 22, and the connecting part 52 is provided with an extension block 522 on the side facing the clearance notch 22. The magnet 4 is fixedly connected to the extension block 522. In this embodiment, by providing the extension block 522, not only is the assembly of the magnet 4 facilitated, but the stability of the position of the magnet 4 is also improved, preventing the magnet 4 from moving during use and affecting the detection reliability between the Hall sensor and the magnet 4. Specifically, the extension block 522 is inclined upward relative to the first cavity 521, and the extension block 522 extends outward from the clearance notch 22, thus providing clearance for the movement of the operating member 2 and preventing movement jamming. In some embodiments, the magnet 4 can be fixed to the extension block 522 by means of bonding, snap-fitting, etc. In some embodiments, the magnet 4 can also be integrally injection molded with the extension block 522 as an insert, which can increase the connection strength between the magnet 4 and the extension block 522, prevent the magnet 4 from moving or falling off, better ensure the stability of the position of the magnet 4, and thus improve the detection accuracy of the Hall sensor.

[0056] Optionally, in this embodiment of the invention, the abutment block 6 is installed at the clearance notch 22 and fixedly connected to the operating member 2. A mounting plate 62 protrudes from the top of the abutment block 6, and a portion of the flexible circuit board 9 is fixed to the mounting plate 62. The Hall sensor is fixed to the flexible circuit board 9 on the mounting plate 62. The mounting plate 62 is parallel to and spaced apart from the sidewall of the extension block 522. This achieves reliable installation of the Hall sensor, allowing the Hall sensor to move synchronously with the operating member 2. Furthermore, since the mounting plate 62 is parallel to the sidewall of the extension block 522, it ensures that the Hall sensor and the magnet 4 are precisely aligned, improving the detection sensitivity between the Hall sensor and the magnet 4.

[0057] Optionally, at least a portion of the flexible circuit board 9 passing through the fixing part 51 extends along the length direction of the operating member 2. This reduces the number of bends of the flexible circuit board 9 during wire threading, which helps extend the service life of the flexible circuit board 9, facilitates the wire threading operation, and saves the space occupied by the flexible circuit board 9 in the handle. Furthermore, at least a portion of the wire threading groove 511 extends along the length direction of the operating member 2 to adapt to the structure of the flexible circuit board 9 and reduce the bending of the flexible circuit board 9.

[0058] like Figure 7 As shown, in an optional embodiment, the cable guide 511 has a straight-line structure. The entire cable guide 511 extends along the length of the operating member 2 and passes through the opposite sides of the fixing part 51. The portion of the flexible circuit board 9 that passes through the cable guide 511 extends along the length of the operating member 2. This allows the flexible circuit board 9 to pass directly through the cable guide 511 into the steering wheel base 200 without bending inside the handle. Then, the flexible circuit board 9 can achieve electrical connection with the steering wheel circuit board 300 by a single bend. Figure 10 As shown, in this scheme, a wire hole 202 connected to the wire groove 511 is also provided on the steering wheel base 200. The wire hole 202 is located on the side of the wire groove 511 away from the operating member 2. The flexible circuit board 9 passes through the wire groove 511 and the wire hole 202 in sequence and is electrically connected to the steering wheel circuit board 300.

[0059] like Figure 8 As shown, in another optional embodiment, the wire-passing groove 511 has an L-shaped structure, wherein a portion of the wire-passing groove 511 extends along the length direction of the operating member 2 and passes through one side of the fixing part 51, and a portion of the wire-passing groove 511 extends in a direction perpendicular to the operating member 2 and passes through the end of the fixing part 51 away from the connecting part 52. Furthermore, as... Figure 9 and Figure 10As shown, the steering wheel base 200 is provided with a snap-fit ​​groove 201, and the fixing part 51 is snap-fitted into the snap-fit ​​groove 201. The bottom of the snap-fit ​​groove 201 has a through hole 203, and the outlet of the wire-passing groove 511 is connected to the through hole 203. The flexible circuit board 9 passes through the wire-passing groove 511 and is adapted to be bent into an L-shape. After the flexible circuit board 9 passes through the wire-passing groove 511 and the aforementioned through hole 203 in sequence, it can achieve electrical connection with the steering wheel circuit board 300. This solution eliminates the need to open an additional wire-passing hole 202 on the steering wheel base 200, which helps to simplify the structure of the steering wheel base 200. In addition, the extension direction of the flexible circuit board 9 is consistent with the direction of the fixing part 51 being inserted into the snap-fit ​​groove 201, so there is no interference during insertion and installation, which further improves the ease of assembly of the combination switch handle 100 and the steering wheel base 200.

[0060] Furthermore, to provide the combination switch handle with control functions for over 100 motion modes, different rotation structures can be selected according to the rotational actions corresponding to the functions to be achieved. Figure 1 Taking the orientation of the combination switch handle 100 as an example, in this embodiment, both the left and right combination switch handles 100 can only rotate vertically relative to the steering wheel base 200; or, one of the left and right combination switch handles 100 can only rotate vertically relative to the steering wheel base 200, while the other can rotate both vertically and horizontally relative to the steering wheel base 200 in an inward or outward direction perpendicular to the plane of the paper; or, both the left and right combination switch handles 100 can rotate both vertically and horizontally relative to the steering wheel base 200 in an inward or outward direction perpendicular to the plane of the paper. For example, Figure 1 The combination switch handle 100 on the left side is a steering handle. When the combination switch handle 100 is moved up and down, it controls the corresponding turn signal of the vehicle to be turned on. When the combination switch handle 100 is moved in the inward or outward direction, it controls the switching between high and low beams of the vehicle. For example, Figure 1 The combination switch handle 100 on the right side is a gear shift handle. When the combination switch handle 100 is moved up and down, it can control the vehicle to enter the corresponding gear, such as drive, reverse, or neutral. For example, Figure 1 The combination switch handle 100 on the right side is a windshield wiper handle. When the combination switch handle 100 is moved up and down, it can control the windshield wipers to turn on or off. When the combination switch handle 100 is moved in the inward or outward direction, it can control the windshield washer fluid spray system of the vehicle to turn on or off.

[0061] In some embodiments, such as Figure 4As shown, to enable the operating member 2 to rotate vertically, the receiving cavity 21 has connecting holes 211 on its opposite side walls near the fixed part 51. Simultaneously, a rotating block 53 is provided at the end of the connecting part 52 near the fixed part 51. Each end of the rotating block 53 has a first shaft 531 extending in a first direction, and the two first shafts 531 are rotatably connected to the two connecting holes 211. This allows the operating member 2 to rotate around the first shafts 531, thus enabling the operating member 2 to rotate vertically relative to the connecting part 52. This design is simple in structure, easy to manufacture, and prevents the operating member 2 from disengaging from the rotating block 53, ensuring the reliability of the operating member 2's rotation.

[0062] In some embodiments, such as Figure 4 As shown, to enable the operation member 2 to rotate in the inward and outward directions, a through second cavity 523 is provided at one end of the connecting part 52 near the fixing part 51. The rotating block 53 is installed in the second cavity 523, and both ends of the rotating block 53, which has a first shaft 531, protrude from the second cavity 523. A second shaft 532 extending in the second direction is also provided inside the rotating block 53, and is rotatably connected to the second cavity 523 through the second shaft 532. This allows the operation member 2 to drive the rotating block 53 to rotate around the second shaft 532, that is, to rotate relative to the connecting part 52 in the inward and outward directions. It should be noted that there is a clearance space between the second cavity 523 and the rotating block 53 so that the rotating block 53 can rotate smoothly within the second cavity 523. The above arrangement enables the operation member 2 to rotate in both the up-down and inward and outward directions simultaneously through a single rotating block 53, making the handle structure more compact and reasonable, and improving space utilization.

[0063] Furthermore, the first axis 531 is perpendicular to the second axis 532. Since drivers are accustomed to controlling the turn signals by moving the combination switch handle 100 up and down, and controlling the high and low beam switching by moving the combination switch handle 100 inward and outward, in order to match the driver's operating habits, this embodiment preferably makes the first axis 531 perpendicular to the second axis 532, thereby ensuring that the two rotation directions are perpendicular to each other. This not only helps to improve the operating feel, but also makes it easier to distinguish different control actions and reduces the possibility of driver misoperation.

[0064] Optionally, the combination switch handle 100 further includes a handle housing, with the connecting part 52, operating member 2, piston 8, flexible circuit board 9, sensing element 3, and magnet 4 all disposed within the handle housing. The operating member 2 is arranged along the length of the handle housing and is rigidly fixed to it. In this embodiment, the end of the handle housing near the steering wheel base 200 is open, and the fixing part 51 extends through the open portion of the handle housing and is fixed to the steering wheel base 200. Because the handle housing is fixed to the operating member 2 and the fixing part 51 is fixed to the steering wheel base 200, the operating member 2 can be rotated relative to the steering wheel base 200 by moving the handle housing.

[0065] Optionally, in some embodiments, the combination switch handle 100 further includes a micro switch, which is disposed within the handle housing and fixed to the operating member 2. For example, the micro switch can be a wiper switch, washer switch, etc. When a button on the surface of the combination switch handle 100 is pressed, the corresponding micro switch is triggered, thereby controlling the corresponding function of the vehicle. The above configuration further improves the integration and control method diversity of the combination switch handle 100.

[0066] This invention also provides a steering wheel assembly, including a steering wheel base 200 and a steering wheel circuit board 300, and further including the aforementioned combination switch handle 100, which is disposed on at least one side of the steering wheel base 200. The steering wheel assembly provided by this invention improves the integration of the combination switch handle 100, saves space occupied by the clock spring area at the center of the steering wheel base 200, and facilitates the arrangement of other functional structures within the steering wheel base 200.

[0067] Optionally, such as Figure 1 and Figure 2 As shown, in this embodiment, a combination switch handle 100 is provided on each side of the steering wheel base 200, thereby facilitating different operations by the driver's left and right hands and improving control convenience. It should be noted that the left and right combination switch handles 100 integrate different functions. For example, the left combination switch handle 100 can be used to control the turn signals, high / low beam switching, etc., while the right combination switch handle 100 can be used to control the wipers, gear shift, etc.

[0068] To facilitate the installation of the combination switch handle 100 and the steering wheel base 200, this embodiment provides snap-fit ​​slots 201 on both sides of the steering wheel base 200. The fixing parts 51 of the two combination switch handles 100 are inserted and fixed into the two snap-fit ​​slots 201 in a one-to-one correspondence. This arrangement enables rapid assembly of the combination switch handle 100 and the steering wheel base 200, improves production efficiency, and has a simple connection structure, is easy to install, and saves costs. Specifically, the snap-fit ​​slots 201 in this embodiment are square slots, and the fixing parts 51 have a square structure. When the fixing parts 51 are inserted into the snap-fit ​​slots 201, they will not rotate relative to the snap-fit ​​slots 201, thereby ensuring the stability of the position of the connecting housing 5.

[0069] In this embodiment, the fixing part 51 is also provided with a wire-passing groove 511, and the steering wheel base 200 is provided with a wire-passing hole 202 communicating with the wire-passing groove 511. The flexible circuit board 9 passes through the wire-passing groove 511 and the wire-passing hole 202 in sequence and is electrically connected to the steering wheel circuit board 300. This realizes the electrical connection between the combination switch handle 100 and the steering wheel base 200. Furthermore, the wire-passing groove 511 is in the shape of a straight line and extends along the length direction of the operating member 2. The wire-passing hole 202 is provided on the side of the wire-passing groove 511 away from the operating member 2. This arrangement can reduce the number of bends of the flexible circuit board 9 during wire passing, which is beneficial to extending the service life of the flexible circuit board 9 and facilitating the wire passing operation.

[0070] This invention also provides a vehicle including the aforementioned steering wheel assembly. Exemplarily, the vehicle can be an automobile, a new energy electric vehicle, a diesel vehicle, etc. The vehicle provided in this embodiment, by employing the aforementioned steering wheel assembly, improves the integration of the combination switch handle 100, saves space within the steering wheel base 200, and is easy to assemble, thus helping to reduce costs.

[0071] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
