Description

Technical Field

[0001] The present application relates to a handlebar clamping device and a handlebar switch. Background Art

[0002] On vehicles (such as two-wheeled motorcycles, three-wheeled electric vehicles, and four-wheeled off-road vehicles), the handlebars often require electrical switches (i.e., handlebar switches) to facilitate control of vehicle functions. In the prior art, the handlebars typically have positioning holes, while the housing of the handlebar switches is designed with positioning pins. During installation, the handlebar switch is inserted into the handlebar and secured by aligning the positioning pins with the positioning holes.

[0003] However, this installation method has the following problems:

[0004] 1. Poor compatibility: Since handlebars and handlebar switches are usually produced by different manufacturers and the industry has not yet formed a unified production standard, the size and position of the locating pins and locating holes often vary, increasing assembly difficulties.

[0005] 2. Complex operation: The alignment of the locating pin and the locating hole usually occurs inside the handle switch housing, making it difficult for installers to visually observe the alignment, increasing installation complexity and reducing assembly efficiency;

[0006] 3. Insufficient stability: During long-term use, due to the single fixing method, the connection between the positioning pin and the positioning hole is prone to loosening, affecting the stability and durability of the handle switch. Summary of the Invention

[0007] The present application provides a handlebar clamping device. The clamping device according to the present application can overcome at least one or more problems existing in the prior art.

[0008] In a first aspect of the present application, a handlebar tube clamping device is provided, comprising a clamping hoop, the clamping hoop comprising two hoop bodies with concave surfaces, the concave surfaces on the hoop bodies extending along the length direction of the clamping hoop, the concave surfaces of the two hoop bodies being arranged opposite to each other, thereby forming a clamping cavity between the two hoop bodies that matches the shape of the handlebar tube; wherein, the two hoop bodies of the clamping hoop are connected on one side by a fastener with an adjustable connection distance, and on the other side by a hinge.

[0009] In one possible implementation, the above-mentioned hinge includes a female head placed on one hoop body and a male head placed on another hoop body. The female head is provided with a socket for accommodating the insertion of the male head. The male head is hook-shaped and adapted to the position of the socket of the female head. The male head can be flipped relative to the female head.

[0010] In one possible implementation, the socket size of the female connector is slightly larger than that of the male connector, and the male connector is bent in a direction away from the hoop body where the female connector is located.

[0011] In one possible implementation, the fastener includes a rivet nut provided on one hoop body and a bolt provided on another hoop body. The clamping range of the clamping hoop can be adjusted by adjusting the connection distance between the bolt and the rivet nut.

[0012] In a possible implementation, the outer peripheral surface of the hoop body is provided with a clamp extending in the radial direction of the clamping hoop, and the clamp extends from one side of the hoop body and is bent outwardly to form.

[0013] In one possible implementation, the clamp includes a limiting portion and a hook portion. The limiting portion is parallel to the end face of the hoop body, and its free end is bent toward one side of the hoop body, forming a hook-shaped structure.

[0014] In one possible implementation, the hoop body is provided with a fixed end for connecting to the handle switch housing.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Improved compatibility: The clamping device uses an adjustable structure of the clamping hoop and fasteners to flexibly adjust the clamping range to adapt to different sizes of directional handlebars, avoiding assembly errors caused by inconsistent production standards;

[0017] 2. Simplified installation: One side of the clamp is connected by a hinge, and the other side is adjusted by fasteners. The hinge design allows the clamp to be easily inserted into the handlebar tube at a large angle, simplifying the installation process and improving operational convenience and efficiency.

[0018] 3. Enhanced connection stability: The hinged joint consists of a male and female head, securely connected by a snap-fit ​​structure. After the clamp is tightened, the fastener can further increase the contact area between the clamp body and the handlebar tube, effectively reducing stress concentration and improving the connection stability and service life of the device.

[0019] 4. Protect structural integrity: The design of the rivet nut increases the contact area between the threaded mouth and the hoop body, disperses the load, reduces the risk of damage to the threaded mouth due to long-term use or high load conditions, and improves the durability of the device.

[0020] The second aspect of the present application also provides a handle switch, which includes the above-mentioned clamping device and shell. The clamping device is installed inside the shell. Windows are provided on the shell at the openings at both ends of the clamping hoop of the clamping device. The shell is also provided with a cavity connected to the clamping hoop fastener. The installation tool can be inserted into the cavity from the outside of the shell to adjust the fastener.

[0021] In a possible implementation, the housing is provided with a slot adapted to the clamping head of the clamping hoop, and the clamping head limits the housing where the slot is located from rotating in the circumferential direction of the pipe.

[0022] In one possible implementation, a positioning inner shell is clamped and fixed between the fixed end of the clamping hoop and the boss column inside the outer shell.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. Easy and efficient installation: The housing cavity is connected to the fasteners, and installation can be completed with external tools. There is no need to align the positioning holes on the pipe, which greatly improves installation efficiency.

[0025] 2. Strong compatibility: The adjustable function of the clamping ring enables the handle switch to adapt to various specifications of directional handlebars, eliminating the incompatibility problem caused by dimensional errors of traditional locating pins and locating holes;

[0026] 3. More stable structure: The card slot on the handle switch housing cooperates with the card head of the clamping device to limit the rotation of the housing in the circumferential direction of the handlebar tube, increase the contact area between the housing and the clamping hoop, reduce the concentrated force on the fixed end screw, avoid the boss column from breaking, and enhance the stability of the overall connection;

[0027] 4. Optimized wiring harness management: The clamping device’s clip design also has a wiring harness fixing function, preventing the wiring harness inside the handle switch from loosening or slipping, thereby improving safety and overall reliability.

[0028] It should be noted that various possible implementations of any of the above aspects can be combined under the premise that the solutions are not contradictory. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present application will be described below with reference to the accompanying drawings, which illustrate several embodiments of the present application. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present application more complete and fully illustrate the scope of protection of the present application to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide many additional embodiments.

[0039] It should be understood that throughout the drawings, like reference numerals represent like elements. In the drawings, the dimensions of certain features may be distorted for clarity. The terms used in this specification are intended only to describe specific embodiments and are not intended to limit this application. All terms (including technical and scientific terms) used in this specification have the meanings commonly understood by those skilled in the art, unless otherwise defined. For the sake of brevity and / or clarity, well-known functions or structures may not be described in detail.

[0040] On vehicles (such as two-wheeled motorcycles, three-wheeled electric vehicles, and four-wheeled off-road vehicles), the steering handlebar 300 typically houses an electrical switch (i.e., a handlebar switch 200) for controlling equipment. In the prior art, the steering handlebar 300 is provided with a positioning hole, and the housing of the handlebar switch 200 is provided with a positioning pin. During installation, the handlebar switch 200 is inserted into the steering handlebar 300 and then secured by aligning the positioning pin with the positioning hole.

[0041] However, because the handle switch 200 and the direction handle tube 300 are produced by different manufacturers and lack unified production standards within the industry, there are design errors in size and position between the two, which directly increases the difficulty of assembly. Furthermore, the alignment pin and the alignment hole are connected inside the handle switch 200 housing, making it impossible for the installer to visually observe the alignment, making the docking operation more difficult and inefficient. These issues significantly affect the ease and consistency of assembly of the handle switch 200 in actual applications.

[0042] On the one hand, the embodiment of the present application provides a clamping device for the steering handle 300, please refer to Figures 2 to 5 The clamping device mainly includes a clamping hoop 100, which is composed of two hoop bodies 10 with concave surfaces. The concave surfaces extend along the length of the clamping hoop 100, and the concave surfaces of the two hoop bodies 10 are arranged opposite each other, thereby forming a clamping cavity between the two hoop bodies 10 that matches the shape of the steering handle tube 300. One side of the clamping hoop 100 is connected by a fastener 20 with an adjustable connection distance, and the other side is connected by a hinge 30, forming an annular clamping device as a whole.

[0043] Specifically, the hinge 30 consists of a female connector 31 on one side of the hoop body 10 and a male connector 32 on the other side. The female connector 31 has a socket for the male connector 32, which is hook-shaped and fits snugly into the socket of the female connector 31. The male connector 32 can be tilted relative to the female connector 31 at a certain angle, allowing one side of the hoop body 10 to open relative to the other side, thereby allowing the clamping hoop 100 to be inserted into the handle tube 300 at a larger angle.

[0044] Furthermore, the socket of the female connector 31 is slightly larger than the male connector 32, and the male connector 32 is bent toward the side of the ferrule 10 away from the female connector 31. This design ensures that the male connector 32 and the female connector 31 are securely engaged when the fastener 20 is connected, preventing separation. When the fastener 20 is removed, the male connector 32 can be quickly separated from the female connector 31 by flipping it to a specific angle, thereby achieving disassembly.

[0045] In addition, the male connectors 32 shown in the figure are evenly spaced and arranged in three numbers, which match the three corresponding sockets on the female connector 31, ensuring that the clamping device has good stability and convenience during assembly and disassembly.

[0046] Specifically, the fastener 20 is composed of a rivet nut 21 provided on one hoop body 10 and a bolt 22 provided on the other hoop body 10. By adjusting the connection distance between the bolt 22 and the rivet nut 21, the clamping range of the clamping hoop 100 can be adjusted.

[0047] The rivet nut 21 can significantly increase the contact area between the nut threaded opening and the hoop body 10 (sheet metal part), thereby dispersing the load, reducing stress concentration, and effectively reducing the risk of damage to the threaded opening due to long-term use or high-load conditions, further improving the durability and reliability of the clamping device.

[0048] The outer circumference of at least one hoop body 10 is provided with a clamp head 40 extending in the radial direction of the clamping hoop 100 for restraining the wiring harness in the handle switch 200. When the hoop body 10 is a sheet metal part, the clamp head 40 extends from one side of the hoop body 10 and is bent outward.

[0049] Furthermore, the clamp head 40 is composed of a stopper 41 and a hook 42. The stopper 41 is parallel to the end surface of the clamp body 10, and its free end is bent toward the side of the clamp body 10, forming a hook-shaped structure. This design can more firmly clamp the wiring harness in the handle switch 200, preventing the wiring harness from loosening or slipping.

[0050] At least one of the hoop bodies 10 is provided with a main fixing end 50a for connecting to a boss column on the housing 201 of the handle switch 200 (the boss column is not shown in the figure). Figure 1 As shown, the housing 201 of the handle switch 200 is divided into an upper housing and a lower housing. The installation steps are as follows: First, secure the lower hoop body 10 to the boss post on the lower housing via the main fixing end 50a using screws. Then, connect the upper hoop body 10 to the lower hoop body 10 using the hinge 30. Finally, secure the upper and lower housings together using screws. The hinge 30 ensures that the upper hoop body 10 does not interfere with the connection between the lower hoop body 10 and the lower housing during installation, improving installation convenience.

[0051] When the hoop body 10 is a sheet metal part, one side of the lower hoop body 10 can be extended to form a plate-shaped secondary fixing end 50b. The cooperation between the main fixing end 50a and the secondary fixing end 50b can enhance the connection stability between the lower hoop body 10 and the lower shell. Figure 2 As shown, the secondary fixing end 50b can also cooperate with the boss column in the lower shell by connecting the positioning inner shell 204. The positioning inner shell 204 is used to fix the button on the surface of the switch handle.

[0052] On the other hand, the present invention provides a handle switch 200 using the above-mentioned clamping device. Figure 1 、 Figure 6 and Figure 7The handle switch 200 comprises the aforementioned clamping device and a housing 201, with the clamping device mounted within the housing 201. Windows 202 are provided on the housing 201 at the ends of the clamping device's clamping band 100, allowing the handle switch 200 to be smoothly inserted into the handlebar tube 300 from one end. The housing 201 also has a cavity 205 that communicates with the fastener 20 of the clamping band 100. An installation tool can be inserted into the cavity 205 from outside the housing 201 to adjust the fastener 20.

[0053] During installation, simply insert the installation tool from outside the housing 201 into the cavity 205 until it reaches the bottom, and then adjust the fastener 20. Adjusting the fastener 20 tightens the clamping collar 100, thereby firmly securing the clamping device to the handlebar tube 300. Compared to traditional methods, this design eliminates the need to align locating pins or screws with locating holes on the handlebar tube 300, significantly improving installation efficiency. It also eliminates assembly issues caused by dimensional errors, greatly enhancing the compatibility between the handlebar switch 200 and the handlebar tube 300.

[0054] The housing 201 of the handlebar switch 200 is provided with a slot 203 at a position corresponding to the clamp head 40. The clamp head 40 restricts the circumferential rotation of the housing 201 where the slot 203 is located, thereby increasing the circumferential contact area between the housing 201 and the clamping hoop 100. This structure effectively reduces the concentrated stress on the fixing screw, preventing the boss post connecting the housing 201 and the clamping hoop 100 from breaking due to excessive force.

[0055] In addition, as mentioned above, the clamp head 40 also has the function of fixing the wiring harness inside the shell 201, which can effectively constrain the position of the wiring harness and prevent it from loosening or displacement during use, thereby further improving the overall stability and service life of the handle switch 200.

[0056] Production and assembly stage:

[0057] 1. Secure the hoop body 10, the positioning inner shell 204 (available on some models), and the lower shell of the outer shell 201 of the clamping hoop 100 together with screws.

[0058] 2. When tightening the screws at the main fixing end 50a, first remove the upper part of the clamp 100.

[0059] 3. After the main fixing end 50a is fixed, connect the upper hoop body 10 to the lower hoop body 10:

[0060] Insert the female connector 31 of the upper hoop body 10 into the male connector 32 of the lower hoop body 10;

[0061] Fold the upper hoop body 10 so that one end of the rivet nut 21 falls on the upper part of the bolt 22 of the lower hoop body 10;

[0062] 4. Use a hexagonal wrench to insert the hexagonal wrench into the cavity 205 of the housing 201 to the inner bottom, and turn the bolt 22 to make it initially connected with the rivet nut 21.

[0063] 5. Finally, fix the upper shell and lower shell of the housing 201 with screws to complete the factory assembly of the handle switch 200.

[0064] Merchant or consumer installation stage:

[0065] 1. Align the window 202 of the handle switch 200 with one end of the handlebar tube 300 and insert it into the handlebar tube 300;

[0066] 2. Adjust the position and angle of the handle switch 200 to the appropriate position;

[0067] 3. Insert a hexagonal wrench into the bottom of cavity 205 of housing 201 and turn the nut until the clamping hoop 100 tightens the tube 300.

[0068] 4. After confirming that the fastening is complete, the installation of the handle switch 200 is completed.
