[0042] Refer to the attached Figure 1 - attached Figure 7, an external automobile operating lever, used in conjunction with a steering wheel 4, comprises a casing 1, a controller 2 and a driving member 3; a casing cavity 10 is provided inside the casing 1, a notch 100 connected to the outside is provided on one side of the casing cavity 10, and the casing cavity 10 can be sleeved with a support arm 40 of the steering wheel 4 through the notch 100, so that the casing 1 can be detachably mounted on the steering wheel 4; the controller 2 is mounted on the casing 1 and connected to a signal of a central control screen (not shown in the figure) or a bus control unit (not shown in the figure); the driving member 3 is mounted on the casing 1 and is located below the steering wheel 4, and turning the driving member 3 can drive the controller 2 to send a control signal to the central control screen or the bus control unit of the automobile.

[0043] Specifically, during installation, align the notch 100 with the arm 40 of the steering wheel 4, then move the cover 1 so that the arm 40 passes through the notch 100 and is inserted into the cover cavity 10, and the cover 1 can be fixed on the steering wheel 4; since the driving member 3 is located below the steering wheel 4, it will not interfere with the user's normal use of the steering wheel 4, and it is convenient for the user to contact the driving member 3; when the user turns the driving member 3, the controller 2 can be driven to send a control signal to the car's central control screen or bus control unit, thereby controlling the corresponding function of the car. During disassembly, the cover 1 is forced to expand the notch 100, and the cover 1 is moved downward to separate the arm 40 from the cover cavity 10.

[0044] In summary, the utility model designs a sleeve cavity 10 and a notch 100 on the sleeve shell 1 to cooperate with the support arm 40, so that the sleeve shell 1 can be detachably installed on the steering wheel 4, which is convenient for installing the controller 2 and the driving member 3 on the steering wheel 4 for use, and is also convenient for removing the controller 2 and the driving member 3 for maintenance; therefore, compared with the prior art, this solution can solve the problem of difficult installation of the operating lever without disassembling the steering wheel 4, thereby improving the convenience of use.

[0045] It should be noted that, since the technology of driving the controller 2 to send a control signal to the automobile central control screen or bus control unit through the driving component 3 and then controlling the automobile is a prior art in the automobile field, the specific circuit structure and control program thereof are not elaborated in detail in the utility model; in actual use, the manufacturer can preset the corresponding program for the controller 2 according to actual needs, so that the controller 2 has the function of controlling the start and stop of automobile accessories such as the left and right turn signals, high and low beam lights, wipers, and even the function of controlling the gear position of the automobile.

[0046] On the other hand, regarding the power supply problem of the controller 2, a button battery can be set inside the controller 2 for power supply.

[0047] See attached Figure 1 -Attached Figure 5 The outer wall of the support arm 40 is closely attached to the inner wall of the sleeve cavity 10, so that the sleeve cavity 10 and the support arm 40 are interference fit; this design prevents the sleeve shell 1 from shaking and improves the installation stability of the sleeve shell 1.

[0048] Refer to the appendix Figure 1 - appendix Figure 6 In order to endow the housing 1 with certain deformation ability and recovery ability and ensure that it can stably clamp the support arm 40, the housing 1 can be made of elastic materials such as plastic and rubber. In this embodiment, the housing 1 is preferably made of plastic.

[0049] Specifically, plastic is a kind of high molecular polymer, which consists of synthetic resin and various additives, and has plasticity and elasticity. Even at low temperatures, plastic still exhibits good anti-creep characteristics, geometric stability and anti-impact characteristics. These characteristics endow plastic with certain elasticity; therefore, the structure of the housing 1 made of plastic is more stable and has a longer service life.

[0050] Refer to the appendix Figure 2 - appendix Figure 7 There is a hook strip 101 with a bent design at the notch 100. When the support arm 40 is located in the sleeve cavity 10, the hook strip 101 abuts against the top surface of the support arm 40; therefore, the design of the hook strip 101 can increase the contact points between the housing 1 and the support arm 40, so that the housing 1 can be more stably installed on the support arm 40.

[0051] Refer to the appendix Figure 5 - appendix Figure 9 There are various types of controllers 2, which are relatively common in the field of automotive parts. The driving member 3 at least includes an electric structural member or a manual structural member, and the related structures are relatively diverse. Therefore, in the present utility model, there are no restrictions on the type of the controller 2, the specific structure of the driving member 3, and how to drive the controller 2 by the driving member 3; but for the sake of easy understanding, the following embodiments are exemplified here:

[0052] The controller 2 adopts a button box 20, and the driving member 3 includes a shroud 31, a rotating seat 32, a paddle 33 and a spring 34; the shroud 31 is installed on the housing 1 and encloses to form a cover cavity 310 with an activity opening 3100; the rotating seat 32 is fixed on the housing 1 and is located in the cover cavity 310; the tail end of the paddle 33 extends into the cover cavity 310 through the activity opening 3100 and is rotatably connected to the rotating seat 32. The head end of the paddle 33 extends towards the side of the steering wheel 4, and a pressing block 330 corresponding to the button box 20 is provided on the paddle 33; the spring 34 is located in the cover cavity 310 and abuts against the housing 1 and the paddle 33; wherein, the design of the cover cavity 310 can enclose the rotating seat 32 and the spring 34, improving the aesthetic degree while preventing the corresponding components from being exposed and aging, and the design of the activity opening 3100 is used for the up and down movement of the paddle 33, and at the same time can limit the movement range of the paddle 33 to prevent the paddle 33 from swinging excessively.

[0053] Specifically, when in use, flipping the paddle 33 upwards can drive the pressing block 330 to contact the button box 20, and then send a control signal to the vehicle central control screen or the bus control unit through the button box 20. During this process, the spring 34 compresses to store energy; when the paddle 33 is released, the spring 34 releases energy and returns to drive the paddle 33 to move downwards to reset; by repeatedly flipping the paddle 33 to contact the button box 20, the button box 20 can send corresponding control signals to the vehicle central control screen or the bus control unit, so as to control various functions of the vehicle.

[0054] Refer to the appendix Figure 6 - appendix Figure 11 Furthermore, for the convenience of disassembling and assembling the shroud 31, in the present utility model, the housing 1 is provided with a buckle 11 and a stud 12, and the shroud 31 is provided with a bayonet 311 and a screw hole 312 with a bolt (not shown in the figure). The buckle 11 corresponds to the buckle 11, and the screw hole 312 and the bolt correspond to the stud 12.

[0055] Specifically, when the buckle 11 is snapped into the bayonet 311, the bolt can pass through the screw hole 312 and be threadedly connected to the stud 12 to fix the shroud 31 to the housing 1; similarly, by screwing the bolt out of the stud 12 and moving the shroud 31 so that the bayonet 311 is disengaged from the buckle 11, the shroud 31 can be removed from the housing 1.

[0056] Refer to the appendix Figure 6 - appendix Figure 11 In order to ensure that the spring 34 can be installed more stably, in the present utility model, the housing 1 is provided with a sleeve 13 in the cover cavity 310, and the paddle 33 is provided with a block 331 in the cover cavity 310. The block 331 is movably located in the sleeve 13; the spring 34 is arranged in the sleeve 13 and abuts against the bottom wall of the sleeve 13 and the block 331.

[0057] Specifically, when in use, when the paddle 33 is flipped upwards, the block 331 moves downwards in the sleeve 13 and compresses the spring 34 to store energy; when the paddle 33 is released, the spring 34 releases energy and returns to drive the block 331 to move upwards in the sleeve 13, thereby driving the paddle 33 to reset.

[0058] Refer to the appendix Figure 5 - appendix Figure 10 The manufacturer can bond the button box 20 to the housing 1 with glue or fix the button box 20 to the housing 1 with screws. Since there are various methods, the present utility model does not limit this. However, for the convenience of disassembling the button box 20, in this embodiment, the housing 1 is provided with a fixing frame 14. The fixing frame 14 and the housing 1 enclose a fixing cavity 140. An installation opening 141 and a through opening 142 communicating with the outside are formed on the side wall of the fixing cavity 140; the button box 20 can pass through the installation opening 141 and enter the fixing cavity 140, and the button box 20 is in interference fit with the fixing cavity 140. The key positions of the button box 20 are aligned with the through opening 142 to correspond to the pressing block 330.

[0059] Specifically, during installation, align the button box 20 with the installation opening 141, and then push the button box 20 forcefully to drive the button box 20 through the installation opening 141 and snap it into the fixing cavity 140 for fixed placement, and make the key positions of the button box 20 be at the through openings 142; during disassembly, push the button box 20 forcefully towards the installation opening 141 to make the button box 20 pass through the installation opening 141 and disengage from the fixing cavity 140; therefore, the above structural design facilitates the disassembly and assembly of the button box 20, and there is no need to rely on components such as glue and screws, improving convenience.

[0060] Refer to the appendix Figure 5 - Appendix Figure 10 Moreover, the housing 1 is also provided with a support block 15. The support block 15 protrudes from the bottom side of the fixing cavity 140 and abuts against the bottom surface of the button box 20 to form a heat dissipation gap 150 between the fixing cavity 140 and the button box 20.

[0061] Specifically, during use, the heat generated by the button box 20 can be discharged to the outside through the heat dissipation gap 150 to ensure the normal operation of the button box 20.

[0062] Refer to the appendix Figure 5 - Appendix Figure 10 Moreover, the fixing frame 14 is also provided with a buffer pad 16. When the pressing block 330 presses and contacts the button box 20, the dial 33 contacts the buffer pad 16.

[0063] Specifically, the design of the buffer pad 16 can limit the upward movement stroke of the dial 33 to prevent the dial 33 from being damaged due to a rigid collision with the housing 1.

[0064] Refer to the appendix Figure 1 - Appendix Figure 6 There are two housings 1 which are respectively installed on the left and right support arms 40 of the steering wheel 4. There are two controllers 2 which are respectively and correspondingly installed on the two housings 1. There are two groups of driving members 3 which are respectively installed on the two housings 1, and the two groups of driving members 3 correspond to the two controllers 2 one by one.

[0065] Specifically, the design of the two housings 1 enables the controllers 2 and the driving members 3 to be provided on both sides of the support arms 40 of the steering wheel 4, making it more convenient for users to operate and improving the usability; and during actual use, the manufacturer can also preset corresponding programs for the two controllers 2 according to actual needs, enabling the two controllers 2 to have various functions for controlling the vehicle. For the sake of easy understanding, the following cases are exemplified here:

[0066] First, the controller 2 located at the left support arm of the steering wheel 4 can be used to control the start and stop of the left turn signal or low beam of the vehicle, and the controller 2 located at the right support arm of the steering wheel 4 is used to correspondingly control the start and stop of the right turn signal or high beam of the vehicle to achieve the switching of the left and right turn signals or the high and low beams.

[0067] Second, the controller 2 located at the left arm of the steering wheel 4 can be used to control the start and stop of the vehicle windshield wiper, and the controller 2 located at the right arm of the steering wheel 4 is used to correspondingly control the swing speed of the vehicle windshield wiper to achieve the switching of the windshield wiper.

[0068] Third, the controller 2 located at the left arm of the steering wheel 4 can be used to control the upshift of the vehicle gear, and the controller 2 located at the right arm of the steering wheel 4 is used to correspondingly control the downshift of the vehicle gear to achieve the upshift and downshift of the vehicle.

[0069] The above three cases are for reference only, and there is no limitation on the actual control program of the controller 2. Therefore, the external operating lever in this application can actually only have a single control function or can also have multiple control functions at the same time, and the manufacturer can make corresponding designs according to user habits.

[0070] It should also be noted that although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application.
