Description

Technical Field

[0001] This utility model belongs to the field of electric bicycle technology, specifically relating to electronic controllers. Background Technology

[0002] In the field of electric vehicles (electric bicycles, electric motorcycles, electric scooters, etc.), the electronic controller is a common component. It integrates multiple switches, has built-in circuitry, and is arranged in a reasonable manner on a single housing. The electronic controller is generally fixed to the handlebars of the vehicle by a retaining ring. Users operate the switches on the electronic controller to control functions such as the horn, lights, and turn signals.

[0003] Early handlebars were typically round tubes, and the wiring of the electronic controllers was mostly external. The disadvantages of external wiring were numerous exposed leads, which affected the aesthetics, and the retaining ring could slip and rotate relative to the round handlebar. To achieve internal wiring, irregularly shaped handlebars with C-shaped grooves were developed. The retaining ring forms a protrusion at the C-shaped groove, which allows for internal wiring. The protrusion and the C-shaped groove also prevent the retaining ring from slipping and rotating relative to the handlebar.

[0004] However, for electronic controllers installed on irregularly shaped handlebars, different manufacturers have various considerations regarding the relevant angles of the controller (the angle of the controller's operating surface, the angle of the C-groove on the handlebar) (similar to the different shapes of cars). This results in different requirements for the angle of the protrusion of the retaining ring. Therefore, different retaining rings are needed (although the angle of the bracket can be adjusted, this can easily lead to difficulties in mold making or even failure to establish the bracket, and can also result in an unattractive bracket design). The large variety of retaining rings increases production costs and makes it easy to confuse different types. Relevant prior art can be found in the applicant's prior patent CN222117005U. Summary of the Invention

[0005] This invention addresses the shortcomings of existing electric controllers with C-grooves that lack universal fixing rings by providing a new electric controller that enables universal fixing ring usage.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an electronic controller, installed on a non-circular handlebar with a C-shaped groove, the electronic controller comprising:

[0007] The bracket includes an opening portion and a switch mounting portion. The opening portion has a horizontal tube hole for the irregularly shaped horizontal tube to pass through, and the switch mounting portion forms a switch receiving cavity, which is connected to the horizontal tube hole.

[0008] The side cover is fixedly connected to the opening.

[0009] The retaining ring has an anti-rotation protrusion that mates with the C-shaped groove;

[0010] Tighten the screws to secure the retaining ring to the side cover, and lock the retaining ring to the irregularly shaped horizontal tube;

[0011] The switch assembly is installed in the switch housing cavity.

[0012] In this invention, the fixing ring is fixed to the side cover by a fastening screw. Compared with the prior art where the fixing ring is fixed to the bracket by a fastening screw, both the fixing ring and the side cover can be used for different electronic controllers (the electronic controllers used by different manufacturers usually have different shapes).

[0013] As an improvement, the side cover is fixed to the opening by axial connecting screws.

[0014] As an improvement, a circumferential positioning structure is formed between the opening and the side cover.

[0015] As an improvement, a positioning notch is formed on the opening, and a positioning part that mates with the positioning notch is formed on the side cover. A screw hole for the fastening screw to pass through is provided on the positioning part.

[0016] As an improvement, the side cover includes an annular base with a fixing groove formed thereon, and a fixing ring is located in the fixing groove.

[0017] As an improvement, the opening includes an outer annular portion and an inner annular portion, the radial length of the inner annular portion is smaller than that of the outer annular portion, and the axial gap between the inner and outer annular portions forms the installation space for the side cover.

[0018] As an improvement, the outer annular portion and the inner annular portion are connected as one unit at the ends axially away from the fixed ring through a tapered portion; the outer annular portion and the inner annular portion are connected as one unit by multiple connecting ribs.

[0019] As an improvement, a wiring notch is provided on the inner ring section.

[0020] As an improvement, the switch mounting part includes a mounting base and a radial connecting part, the radial connecting part is connected to the opening part, the mounting base is tangent to the opening part, and the switch assembly part is located in the radial connecting part.

[0021] As an improvement, the controller also includes a front cover that encloses the switch housing cavity. The front cover is fixed to the bracket by radial connecting screws. The controller also includes a button on the front cover, which has an anti-detachment part located inside the front cover.

[0022] The beneficial effects of the electric controller of this utility model are: the fastening screw fixes the fixing ring to the side cover, which is different from the fastening screw fixing the fixing ring to the bracket in the prior art. Both the fixing ring and the side cover can be used in different electric controllers. Attached Figure Description

[0042] Tighten the screws to secure the retaining ring to the side cover, and lock the retaining ring to the irregularly shaped horizontal tube;

[0043] The switch assembly is installed in the switch housing cavity.

[0044] In this invention, the fixing ring is fixed to the side cover by a fastening screw. Compared with the prior art where the fixing ring is fixed to the bracket by a fastening screw, both the fixing ring and the side cover can be used for different electronic controllers (the electronic controllers used by different manufacturers usually have different shapes).

[0045] Example 1

[0046] See Figures 1 to 9 The electronic controller of Embodiment 1 of this utility model is installed on the irregularly shaped handlebar 8 with a C-shaped groove 81. The electronic controller includes:

[0047] The bracket 1 includes an opening portion 11 and a switch mounting portion 12. The opening portion 11 has a horizontal tube hole for the irregularly shaped horizontal tube 8 to pass through. The switch mounting portion 12 forms a switch receiving cavity, and the switch receiving cavity is connected to the horizontal tube hole.

[0048] Side cover 2 is fixedly connected to opening 11;

[0049] The retaining ring 3 has an anti-rotation protrusion that mates with the C-shaped groove 81;

[0050] Tighten screw 4 to fix the retaining ring 3 to the side cover 2, and lock the retaining ring 3 to the irregularly shaped horizontal tube 8;

[0051] Switch assembly 5 is installed in the switch receiving cavity.

[0052] In this embodiment, the side cover 2 is fixedly connected to the opening portion 11 by axial connecting screws, ensuring reliable connection and facilitating disassembly. The side cover 2 includes an end portion 23 with screw holes 25. Multiple mounting posts 115 are formed on the opening portion 11 of the bracket 1. The axial screws pass through the screw holes 25 of the end portion 23 of the side cover 2 and are screwed into the mounting posts 115. In other embodiments, the side cover 2 can also be snapped onto the bracket 1.

[0053] In this embodiment, a circumferential positioning structure is formed between the opening portion 11 and the side cover 2, and the circumferential positioning structure prevents the side cover 2 from rotating relative to the bracket 1.

[0054] In this embodiment, a positioning notch 116 is formed on the opening portion 11, and a positioning portion 24 is formed on the side cover 2 to mate with the positioning notch 116. A screw hole 25 for the fastening screw 4 to pass through is provided on the positioning portion 24. The outer surface of the positioning portion 24 transitions substantially smoothly with the outer surface of the bracket 1. The screw hole 25 on the positioning portion 24 is a countersunk hole to avoid or reduce the outward protrusion of the head of the fastening screw 4. The side cover 2 is generally cylindrical.

[0055] In this embodiment, the side cover 2 includes an annular base 21, on which a fixing groove 22 is formed, and a fixing ring 3 is located in the fixing groove 22.

[0056] In this embodiment, the opening portion 11 includes an outer annular portion 111 and an inner annular portion 112. The radial length of the inner annular portion 112 is less than that of the outer annular portion 111. The axial gap between the inner annular portion 112 and the outer annular portion 111 forms the mounting space for the side cover 2. The outer end face of the side cover 2 is substantially flush with the outer end face of the outer annular portion 111. The inner end of the side cover 2 abuts against the inner annular portion 112.

[0057] In this embodiment, the outer annular portion 111 and the inner annular portion 112 are connected as one unit at the ends axially away from the fixing ring 3 via a tapered portion 113; the outer annular portion 111 and the inner annular portion 112 are connected as one unit via multiple connecting ribs 114. The mounting post 115 is located at the radial center of the connecting ribs 114.

[0058] In this embodiment, a wiring notch is provided on the inner annular portion 112.

[0059] In this embodiment, the switch mounting part 12 includes a mounting base and a radial connecting part 13. The radial connecting part 13 is connected to the opening part 11, the mounting base is tangent to the opening part 11, and the switch assembly 5 is located in the radial connecting part 13.

[0060] In this embodiment, the electronic controller also includes a front cover 7, which closes the switch receiving cavity. The front cover 7 is fixed to the bracket 1 by radial connecting screws. The electronic controller also includes a button 6 on the front cover 7, which has an anti-detachment part located inside the front cover 7.

[0061] In this embodiment, the structure of the fixing ring 3 can be referred to the accompanying drawings and the prior art.

[0062] See Figure 9 , Figure 9 The electronic controller in the upper middle picture and Figures 1 to 8 Consistency in Figure 9 The electronic controller in the lower image is different from the one in the upper image. This difference arises because different manufacturers use different designs for their electronic controllers, leading to angle variations (usually angle variations are not significant). Figure 9(The difference between the upper and lower figures is not that significant). Since the side cover 2 and the fixing ring 3 form a whole and are fixed to the bracket 1 by axial connecting screws (in the prior art, the fixing ring 3 and the bracket 1 are connected by fastening screws 4, and when the angle changes, only a new fixing ring 3 can be replaced), it is only necessary to reserve the corresponding installation space on the new bracket 1. Specifically in this embodiment, Figure 9 When the upper middle figure is changed to the lower figure, it is only necessary to change the position of the positioning notch 116 and the mounting post 115 on the outer ring part 111 of the bracket 1 of the electronic controller in the lower figure (other shape changes do not affect the installation of the side cover 2 and the fixing ring 3).

[0063] The beneficial effects of the electric controller in Embodiment 1 of this utility model are as follows: the fastening screw 4 fixes the fixing ring 3 to the side cover 2. Compared with the prior art where the fastening screw 4 fixes the fixing ring 3 to the bracket 1, both the fixing ring 3 and the side cover 2 can be used in different electric controllers; the side cover 2 and the bracket 1 are detachably connected by axial connecting screws, and the side cover 2 is easy to disassemble and assemble; compared with the existing structure that does not change the fixing ring but changes the bracket, the bracket mold is easier to open, the aesthetic appearance of the bracket is easier to maintain, and the side cover still needs to be modified.

[0064] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the content described in the above specific embodiments. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
