[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0038] The core of the present utility model is to provide a combination switch for a vehicle, which can reduce the manufacturing difficulty.

[0039] In the first specific embodiment of the combination switch for a vehicle provided by the present utility model, it is specifically applied to an automobile. Please refer to Figures 1 to 7 , the combination switch includes a switch body 1, a wiper handle 3, a lighting handle 2 and a shift-by-wire handle 4, constituting a three-handle combination switch. The lighting handle 2 can also be called a steering handle.

[0040] As Figure 2 shown, the switch body 1 includes a housing assembly, and the housing assembly includes an upper housing 11, a middle housing 12 and a lower housing 13. A main control board, specifically a PCBA assembly, is provided on the middle housing 12 and / or the lower housing 13. The main control board can be arranged on the left or right side in the switch body 1 as required. The main control board is used to control functions such as lighting, steering, wiper, and water spraying. The lighting handle 2, the wiper handle 3 and the shift-by-wire handle 4 can be connected to the main control board. The upper housing 11 and the lower housing 13 are respectively connected to the upper and lower sides of the middle housing 12.

[0041] As Figure 1 shown, the wiper handle 3, the lighting handle 2 and the shift-by-wire handle 4 are connected to the switch body 1. Among them, the wiper handle 3 and the lighting handle 2 are respectively movably connected to the opposite sides of the switch body 1, specifically the left and right sides. It should be noted that in this embodiment, as Figure 1 shown, the lighting handle 2 is located on the left side of the switch body 1, and the wiper handle 3 is located on the right side of the switch body 1, which is applicable to a left-hand drive vehicle (the driver is on the left side and the lighting handle 2 is on the left side of the switch body 1); in other embodiments, as Figure 8 shown in Embodiment 2, the lighting handle 2 is located on the right side, and the wiper handle 3 is located on the left side, which is applicable to a right-hand drive vehicle (the driver is on the right side and the lighting handle 2 is on the right side of the switch body 1).

[0042] As Figures 3 to 5 shown, both the lighting handle 2 and the wiper handle 3 include a handle housing 5 and a control component 6 provided on the handle housing 5.

[0043] Specifically, as Figure 3 and Figure 5As shown in the figure, the control component 6 includes a central shaft 614, a first control ring 62, a first moving contact piece 63, a first curved surface block 64, and a handle control board 66. The central shaft 614 and the first curved surface block 64 are both fixed to the handle housing 5. The first control ring 62 is rotatably connected to the central shaft 614. At least part of the structure of the first control ring 62 is externally disposed on the handle housing 5. The first control ring 62 is pressed against the first curved surface block 64 by a first elastic member 65. The first control ring 62 drives the first moving contact piece 63 to rotate through rotation, so that the first moving contact piece 63 triggers a first static contact piece 661 on the handle control board 66.

[0044] Specifically, as Figure 3 and Figure 5 shown, the first elastic member 65 includes a first steel ball 652 and a first spring 651. The first spring 651 presses the first steel ball 652 against the first curved surface block 64, and the other end of the first spring 651 presses against the first control ring 62. When the first control ring 62 rotates, the first spring 651 drives the first steel ball 652 to slide on the curved surface of the first curved surface block 64, providing different hand feelings. Among them, the moving contact piece can also be called a gold finger or a metal sliding piece.

[0045] Specifically, the handle control board 66 is specifically a control flexible board. On the handle control board 66, static contact pieces such as the first static contact piece 661 can be arranged in an arc, specifically in a flexible board structure.

[0046] It should be noted that the control components 6 in the lighting handle 2 and the wiper handle 3 are electrically connected to different control parts and components on the vehicle to achieve different functions. The lighting handle 2 can achieve lighting controls such as steering, lane changing, high beam, passing lamp, front and rear fog lamps, low beam, outline lamp, automatic headlamp, and adaptive high and low beam. The wiper handle 3 can achieve front wiper (automatic wiper, intermittent wiper), rear wiper, front water spray, and rear water spray, and different gears can correspond to different functions respectively.

[0047] Among them, as Figure 3 and Figure 4 shown, for the specific functions of the lighting handle 2, its first control ring 62 can be used to control the fog lamp, and by selecting first curved surface blocks 64 with different shapes, the cooperation between the first control ring 62 and the first curved surface block 64 can enable the lighting handle 2 to have front and rear fog lamp functions, only front fog lamp or only rear fog lamp.

[0048] In this embodiment, at least some components of the control assembly 6 in the wiper handle 3 and the lighting handle 2 have the same assembly method, generally forming a mirror design, and some structures (such as the first control ring 62) can also be directly made into the same structure to serve as common parts, which can reduce costs. By setting different control functions on the handle control board 66, the corresponding functions of the wiper handle 3 and the lighting handle 2 are respectively realized, increasing the commonality of the structures of the wiper handle 3 and the lighting handle 2, and reducing the manufacturing difficulty of the combination switch.

[0049] For the structures of the control assembly 6 of the lighting handle 2 and the wiper handle 3, other common structures can also be set. Please refer to Figures 3 to 5 , the control assembly 6 further includes a second control ring 67, a second moving contact piece 68, a second curved surface block 69 and a knob 615.

[0050] Among them, the second curved surface block 69 is fixed to the central shaft 614, specifically fixed together through a groove and snap-fit structure. The second control ring 67 is rotatably connected to the central shaft 614. And the first control ring 62 and the second control ring 67 are sleeved on the central shaft 614 in sequence along the axial direction, specifically arranged in sequence along the direction away from the switch body 1. The knob 615 is sleeved and fixed on the second control ring 67, and at least part of the structure of the knob 615 is externally disposed on the handle housing 5, so that rotating the knob 615 can drive the second control ring 67 to rotate around the central shaft 614. The second control ring 67 is pressed against the second curved surface block 69 by a second elastic member 610. The second control ring 67 rotates to drive the second moving contact piece 68 to rotate, so that the second moving contact piece 68 triggers the second static contact piece on the handle control board 66. Based on this part of the setting on the control assembly 6, the commonality of the structures of the lighting handle 2 and the wiper handle 3 can be further improved, and the assembly methods are the same, which can further reduce the manufacturing difficulty of the combination switch.

[0051] Among them, as Figure 3 and Figure 5 shown, the second elastic member 610 includes a second steel ball 6102 and a second spring 6101. The second spring 6101 presses the second steel ball 6102 on the second curved surface block 69, and the other end of the second spring 6101 presses the second control ring 67. When the second control ring 67 rotates, the second spring 6101 drives the second steel ball 6102 to slide on the curved surface of the second curved surface block 69 to provide different hand feelings.

[0052] In addition, for the convenience of assembling the central shaft 614, as Figure 3 and Figure 5 shown, an elastic connecting piece 613 is snap-fixed on the handle housing 5. A convex block 6141 is fixedly arranged on the outer peripheral surface of the central shaft 614, and the convex block 6141 is inserted and fixed in the connecting hole of the elastic connecting piece 613, which is convenient for disassembly and assembly.

[0053] In addition, for the parts where the lighting handle 2 and the wiper handle 3 cooperate with the switch body 1, such as Figure 2 As shown, two curved surface blocks 7 are further provided on the switch body 1, namely a lighting curved surface block 71 that slidably cooperates with the lighting handle 2 for gear shifting, and a wiper curved surface block 72 that slidably cooperates with the wiper handle 3 for gear shifting. An end elastic member 611 and a plunger 612 are provided at one end of the handle housing 5 close to the switch body 1. One end of the end elastic member 611 is connected to the handle housing 5, and the other end presses the plunger 612 against the curved surface block 7. Different gear slots are provided on the curved surface block 7, and the plunger 612 can be switched to move to different gear slots.

[0054] Specifically, as Figure 2 and Figure 3 shown, the lighting handle 2 contacts the lighting curved surface block 71 through the corresponding plunger 612. The movement of the lighting handle 2 drives the corresponding plunger 612 to fit and move on the lighting curved surface block 71 to switch different gears and achieve different hand feelings. As Figure 2 and Figure 5 shown, the wiper handle 3 contacts the wiper curved surface block 72 through the corresponding plunger 612. The movement of the wiper handle 3 drives the corresponding plunger 612 to fit and move on the wiper curved surface block 72 to switch different gears and achieve different hand feelings.

[0055] Specifically, the lighting handle 2 and the wiper handle 3 can be rotated in four directions: up, down, front, and back relative to the corresponding curved surface block 7. In the control part, as Figure 10 shown in the embodiment, a control block 61 is provided on the handle housing 5 and is connected to a swing arm 14. The control block 61 is connected to a first gold finger, and the swing arm 14 is connected to a second gold finger. Among them, in the lighting handle 2, the swing arm connected to its handle housing 5 is the lighting handle swing arm 14, and the second gold finger is the lighting swing arm gold finger 16; in the wiper handle 3, the swing arm connected to its handle housing 5 is the wiper handle swing arm 15, and the second gold finger is the wiper swing arm gold finger 17. The second gold finger can be assembled on the left or right side of the upper housing 11 and the middle housing 12 as required.

[0056] A control board is provided in the switch body 1, specifically a PCB, which can be provided on the main control board of the switch body 1, or separately provided from the main control board and electrically connected. When the handle housing 5 drives the control block 61 to move in the first direction (such as front and back), the first gold finger can trigger the control board. When the handle housing 5 drives the swing arm 14 to move in the second direction (such as up and down), the second gold finger can trigger the control board.

[0057] When the handle (lighting handle 2 or wiper handle) rotates, it drives the corresponding swing arm or control block 61 to move. The swing arm and the control block 61 can slide on the corresponding control board to generate corresponding control signals and achieve corresponding control functions.

[0058] Of course, the lighting handle 2 and the wiper handle 3 may also have different structures according to different requirements.

[0059] As Figure 3 and Figure 4 shown, a key component is also provided in the lighting handle 2, while the key component is not provided in the wiper handle 3. In the lighting handle 2, the key component includes a key 21 provided at the end of the handle housing 5 of the lighting handle 2 away from the switch body 1, a push rod 22 is slidably connected axially in the central shaft 614, and a lighting conductive member 23 is connected to the circumferential surface of the central shaft 614, which may specifically be conductive rubber. The key 21 drives the push rod 22 to move through axial movement, and the push rod 22 pushes the lighting conductive member 23 to move to connect or disconnect from the key 21 control portion on the handle control board 66.

[0060] As Figure 2 shown, a steering return system 111 adapted to the lighting handle 2 may also be provided on the switch body 1, and this structure does not need to be provided for the wiper handle 3. Among them, the lighting handle 2 and the steering return system 111 are respectively connected to the switch body 1. Correspondingly, on the housing assembly of the switch body 1, groove structures adapted to the lighting handle 2 and the steering return system 111 are respectively provided, which is convenient for assembly. In addition, in this assembly method, for the combination switch of left steering and right steering, the groove structure can be set in different directions on the housing assembly to adaptively install the steering return system 111. Except for the different installation directions, the steering return system 111 can be shared by these two combination switches.

[0061] Among them, for the steering return system 11, it may specifically include a return block 1111, a return spring support block 1112, a return spring 1113, a return clip 1114 and other structures. Correspondingly, a handle return block 24, a handle return elastic member 25 and other matching structures can be provided in the lighting handle 2 to achieve return.

[0062] For the stalk shift handle 4, as Figure 1 shown, the gears it can control include D forward gear, R reverse gear, N neutral gear, P parking gear, B engine braking gear, etc. When shifting gears, a curved surface block may not be additionally provided in the switch body 1. As Figure 2 shown, a stalk shift handle curved surface 721 is added to the wiper curved surface block 72. The stalk shift handle 4 is slidably mated with the stalk shift handle curved surface 721 to shift gears and achieve different hand feelings. That is to say, the stalk shift handle 4 and the wiper handle 3 share a curved surface block 7, which can reduce the addition of the curved surface block 7 and the stalk shift handle 4, and the space occupied in the switch body 1. Of course, in other embodiments, the stalk shift handle curved surface 721 may also be provided on the lighting curved surface block 71.

[0063] At this time, for the overall layout of the combination switch, as Figure 1As shown, the windshield wiper handle 3 and the shift-by-wire handle 4 are arranged on the same side of the switch body 1, for example, the right side, and the lighting handle 2 is arranged on the other side of the switch body 1, for example, the left side. This layout of the lighting handle 2, the windshield wiper handle 3 and the shift-by-wire handle 4 is more in line with the operating habits of the vast majority of drivers.

[0064] In addition, in this embodiment, since the combination switch is a three-handle combination switch with three handles: the lighting handle 2, the windshield wiper handle 3 and the shift-by-wire handle 4, it endows the combination switch with more functions, can also make the driver's operation method more convenient, and can also reduce the vehicle cost. In other embodiments, such as Figure 9 and Figure 10 In the embodiment shown, it may not include the shift-by-wire handle 4 and only include the lighting handle 2 and the windshield wiper handle 3 to form a two-handle combination switch.

[0065] Among them, for the three-handle combination switch and the two-handle combination switch, the main differences include that an interface for connecting the shift-by-wire handle 4 needs to be added to the housing assembly of the switch body 1 in the three-handle combination switch, and a shift-by-wire control part needs to be added to the main control board of the switch body 1 (for example, a Hall sensor, an MCU, and a connector need to be added to the main control board to realize the control of the gear position), and it is electrically connected to the shift-by-wire handle 4, and a curved surface adapted to the shift-by-wire handle 4 (i.e., the shift-by-wire handle curved surface 721) needs to be added. Since only the housing assembly part and the structures of individual parts need to be changed for the two types of three-handle and two-handle combination switches, the required space is basically the same, which can meet the condition that the vehicle manufacturer does not need to change the combination switch fixing parts and the assembly space, and can arbitrarily select the three-handle combination switch or the two-handle combination switch for different vehicle design platforms.

[0066] Among them, for different styles of shift-by-wire handles 4 and different angles of windshield wiper handles 3, the housing assemblies can be basically shared. During processing, the structure of one end of different types of handles (shift-by-wire handle 4 or windshield wiper handle 3) that cooperates with the housing assembly remains unchanged, while the other end of the handle far from the housing (refer to the two embodiments in Figure 1 and Figure 8 respectively) can change the appearance shape and angle. When the function remains unchanged or the function is reduced, the corresponding control parts (such as circuits) on the main control board can also be shared.

[0067] In the shift-by-wire handle 4, such as Figure 6 and Figure 7As shown in the figure, a movable P - gear control button 41 is provided at one end of the shift - by - wire handle 4 far away from the switch body 1. A P - gear control board 42 and a shift - by - wire conductive member 43 are arranged inside the shift - by - wire handle 4. The P - gear control board 42 is specifically a PCB, and the shift - by - wire conductive member 43 is specifically conductive rubber. A shift - by - wire static contact piece 421 is arranged on the P - gear control board 42, and a shift - by - wire moving contact piece 431 is arranged on the shift - by - wire conductive member 43. The movement of the P - gear control button 41 can drive the shift - by - wire conductive member 43 to approach or move away from the P - gear control board, thereby making the shift - by - wire moving contact piece 431 communicate with or disconnect from the shift - by - wire static contact piece 421.

[0068] Among them, one shift - by - wire moving contact piece 431 can contact at least two shift - by - wire static contact pieces 421 simultaneously, which can ensure the triggering performance and achieve the anti - failure design. Even if one shift - by - wire moving contact piece 431 fails, the triggering function can still be realized smoothly. In this embodiment, two shift - by - wire moving contact pieces 431 are provided, and four shift - by - wire static contact pieces 421 are provided. One shift - by - wire moving contact piece 431 contacts two shift - by - wire static contact pieces 421 simultaneously.

[0069] Among them, one end of the shift - by - wire conductive member 43 far away from the P - gear control board 42 is bonded with a plastic sheet 45 through glue. Specifically, it is a PC plastic sheet. The P - gear control button 41 contacts and presses the plastic sheet 45, which can effectively solve the problem of unbalanced touch feeling caused by the multi - point contact of the shift - by - wire moving contact piece 431 and the shift - by - wire moving contact piece 431, and can meet the requirements of durability and lifespan.

[0070] Among them, a shift - by - wire control board 46 and a shift - by - wire wire harness 47 are arranged in the shift - by - wire handle 4. One end of the shift - by - wire wire harness 47 is welded to the shift - by - wire control board 46, and the other end is connected to the main control board in the switch body 1 through a connector.

[0071] Among them, a light - transmissive panel 48 is provided on the shift - by - wire handle 4, and light sources are arranged on the shift - by - wire control board 46. Specifically, the light sources are two LEDs.
