Description

Technical Field

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

[0002] When riding electric vehicles (electric bicycles, electric motorcycles, electric scooters, etc.) in cold weather, hands are easily chilled, reducing the user experience and posing certain safety risks. A common solution is to add a heating element to heat the handlebars, typically using resistance wire. However, the process of winding the resistance wire into the handlebar's inner core is mostly done manually, which is inefficient, and the quality of the winding is difficult to guarantee, as is maintaining the wire's position (leading to uneven heating). A very rare approach uses a detachable heating ring, but this requires creating a mounting cavity for the heating ring in the injection-molded silicone handlebar, resulting in a larger radial dimension of the handlebar and introducing wiring issues.

[0003] At the same time, the electrical connection structure of the existing heated throttle (wiring of the heating element, etc.) also has room for improvement: such as the convenience and reliability of installation, anti-collision performance, and start-stop method.

[0004] Furthermore, it's worth noting that with a full grip, compared to a half grip (thumb and forefinger holding and rotating) or a shifter (thumb flicking), the entire hand can be heated, resulting in a better riding experience. For a full grip that swings across the entire grip area, it's also crucial to ensure a reliable connection between the heating cable and the heating element during the swinging motion. Summary of the Invention

[0005] This invention addresses the shortcomings of existing electric bicycle heated throttles that use resistance wires. During assembly, the resistance wires need to be wound around the inner core, resulting in low efficiency, difficulty in ensuring winding quality, and difficulty in maintaining the position of the resistance wires. The invention provides a heated throttle for electric bicycles that uses a heating element instead of resistance wires, improving efficiency and ensuring effective heating. Furthermore, it solves other problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a heated throttle, the heated throttle comprising:

[0007] Fixed components, including magnetic induction elements;

[0008] The oscillating component oscillates relative to the fixed component and includes an inner core, a flexible heating element covering the inner core, an outermost silicone handle, and a conductor fixed to the inner core.

[0009] When the conductor oscillates, its position relative to the magnetic induction element changes, and a corresponding electrical signal is generated in the magnetic induction element.

[0010] The heating throttle of this invention uses a flexible heating element instead of the original resistance wire in its swing assembly. The flexible heating element is fixed to the inner core by means of adhesive or other methods, resulting in high assembly efficiency and stable quality.

[0011] As an improvement, an axial positioning structure is formed between the inner core and the flexible heating element; the flexible heating element has an inner backing adhesive.

[0012] As an improvement, the axial positioning structure includes multiple positioning blocks formed on the inner core and multiple positioning grooves formed on the flexible heating element. Some positioning blocks are circumferentially distributed, and some are axially distributed. The axial dimensions of the positioning blocks and positioning grooves are adapted to each other and position the flexible heating element axially. The circumferential dimension of the positioning blocks is smaller than the circumferential dimension of the positioning grooves, and the thickness of the positioning blocks is greater than the thickness of the flexible heating element; and / or,

[0013] The flexible heating element is wrapped only once; and / or,

[0014] The silicone handle is glued to the inner core.

[0015] As an improvement, the flexible heating element includes a solder joint at its outer end, and the heating throttle also includes a throttle heating lead located in the inner core, which is welded to the solder joint.

[0016] As an improvement, the flexible heating element includes an extension connection portion, which includes an axial extension portion, an outer radial extension portion, a middle radial extension portion, and an inner radial extension portion. The swing assembly also includes an anti-collision assembly located at the outer end of the inner core, which includes a connection gap for the outer radial extension portion to pass through.

[0017] As an improvement, the anti-collision assembly includes an anti-collision block and an anti-collision cover. The anti-collision block and the inner core are snapped together. The inner core has a core slot and a deformation slot for snapping together with the anti-collision block. The anti-collision cover and the anti-rotation block are snapped together. The anti-collision block is located between the inner core and the anti-collision cover. The aforementioned connection gap is formed between the abutting parts of the anti-collision cover and the anti-rotation block.

[0018] As an improvement, the fixing components include:

[0019] Throttle bracket;

[0020] The retaining ring is located in the throttle bracket;

[0021] Tighten the screws to secure the retaining ring and the throttle bracket;

[0022] The throttle cover and throttle bracket are distributed axially, and a magnetic induction element is mounted on it;

[0023] Connecting screws are used to secure the throttle cover to the throttle bracket; and / or,

[0024] The magnetic sensing element includes a Hall element, and the conductor includes a magnet; and / or,

[0025] The flexible heating element uses a polyimide thin-film heating film.

[0026] The beneficial effects of the heating throttle of this utility model are: its swing assembly includes an inner core, a flexible heating element and a silicone grip sleeve. The flexible heating element replaces the winding resistance wire, which improves assembly efficiency. The spacing of the heating wires in the prefabricated flexible heating element is constant, resulting in stable and uniform heating. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be explained and described below. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0045] See Figures 1 to 7 The heating handle of Embodiment 1 of this utility model includes:

[0046] Fixing component 7 includes magnetic induction element 75;

[0047] The oscillating component oscillates relative to the fixed component 7 and includes an inner core 1, a flexible heating element 2 covering the inner core 1, an outermost silicone handle 3, and a conductor fixed to the inner core 1.

[0048] When the conductor swings, its position relative to the magnetic induction element 75 changes, and a corresponding electrical signal is generated in the magnetic induction element 75.

[0049] In this embodiment, the fixing component 7 includes:

[0050] Throttle bracket 71;

[0051] The retaining ring 72 is located in the throttle bracket 71;

[0052] Tighten screw 73 to secure the retaining ring 72 and the throttle bracket 71 together;

[0053] The throttle cover 74 is distributed axially with the throttle bracket 71, and a magnetic induction element 75 is mounted on it.

[0054] Connecting screws are used to secure the throttle cover 74 to the throttle bracket 71. See the attached drawings and prior art for the specific structure of the fixing assembly 7.

[0055] In this embodiment, the flexible heating element 2 has an adhesive backing. The flexible heating element 2 and the inner core 1 are glued together, making assembly relatively easy.

[0056] In this embodiment, an axial positioning structure is formed between the inner core 1 and the flexible heating element 2. The axial positioning structure prevents the flexible heating element 2 from undergoing axial displacement relative to the inner core 1.

[0057] In this embodiment, the axial positioning structure includes multiple positioning blocks 15 formed on the inner core 1 and multiple positioning grooves 21 formed on the flexible heating element 2. Some of the positioning blocks 15 are distributed circumferentially, and some of the positioning blocks 15 are distributed axially. The axial dimensions of the positioning blocks 15 and the positioning grooves 21 are adapted to each other and the axial positioning of the flexible heating element 2 is achieved.

[0058] In this embodiment, the circumferential dimension of the positioning block 15 is smaller than the circumferential dimension of the positioning groove 21 to allow for processing and assembly errors, which is beneficial to the installation of the flexible heating element 2.

[0059] In this embodiment, the thickness of the positioning block 15 is greater than the thickness of the flexible heating element 2. The positioning block 15 protrudes from the outer wall of the inner liner, and the thickness of the positioning block 15 is greater than the thickness of the flexible heating element 2, which facilitates the installation of the silicone handle 3.

[0060] In this embodiment, the flexible heating element 2 is wound only once, and there is a small gap between the two ends of the flexible heating element 2 in the circumferential direction to avoid the flexible heating elements 2 from stacking.

[0061] In this embodiment, the inner core 1 is divided into four sections from the middle to the outer end according to different pipe diameters. However, existing inner cores without heating function have at most or only three sections. The positioning block 15 is formed on the third section 13, and the positioning block 15 is basically flush with the second section 12. Four core slots 16 and two deformation slots 17 are formed on the fourth section 14.

[0062] In this embodiment, the silicone handlebar sleeve 3 is glued to the inner core 1. The silicone handlebar sleeve 3 and the inner core 1 are molded separately, and then glued together. Compared to molding the silicone handlebar sleeve 3 as a single unit with the inner core 1 and the flexible heating element 2, this method is less difficult to manufacture and / or has lower manufacturing costs, and also facilitates later maintenance. The outer end of the silicone handlebar sleeve 3 is sealed.

[0063] In this embodiment, the flexible heating element 2 includes a solder joint 23 located at its outer end, and the heating throttle 01 also includes a throttle heating lead 4 located in the inner core 1.

The swing assembly also includes an anti-collision assembly disposed at the outer end of the inner core 1, which includes a connection gap for the outer radial extension portion 222 to pass through. A solder joint 23 is formed on the inner radial extension portion 224. The anti-collision assembly prevents the flexible heating element 2 from being impacted. There are two solder joints 23, which are respectively connected to the positive and negative electrodes.

[0065] In this embodiment, the anti-collision component includes an anti-collision block 5 and an anti-collision cover 6. The anti-collision block 5 is snapped into the inner core 1, and the anti-collision cover 6 is snapped into the anti-rotation block. The anti-collision block 5 is located between the inner core 1 and the anti-collision cover 6, and the aforementioned connection gap is formed between the abutting part of the anti-collision cover 6 and the anti-rotation block.

[0066] In this embodiment, a notch 51 is formed on the anti-collision block 5, creating the aforementioned connection gap. The anti-collision blocks 5 are symmetrically arranged, with two connection gaps, thereby facilitating the installation of the anti-collision blocks 5.

[0067] In this embodiment, the anti-collision block 5 forms a cone-shaped wire harness mounting portion 54.

[0068] In this embodiment, the magnetic sensing element 75 includes a Hall element, and the conductor includes a magnet.

[0069] In this embodiment, the flexible heating element 2 is a polyimide thin film electric heating film.

[0070] In this embodiment, the heating lead 4 on the flexible heating element 2 includes an anti-detachment component 41 to prevent the heating lead 4 from coming off.

[0071] The beneficial effects of the heating throttle in Embodiment 1 of this utility model are as follows: its swing assembly includes an inner core 1, a flexible heating element 2, and a silicone grip sleeve 3. The flexible heating element 2 replaces the winding resistance wire, resulting in high assembly efficiency. The spacing of the heating wires in the prefabricated flexible heating element 2 is constant, ensuring stable and uniform heating. The flexible heating element 2 uses a polyimide thin film heating film. The power lead of the heating throttle 01 is routed through the inside of the handlebar tube. The power lead and the welding point 23 of the flexible heating element 2 are welded together. Anti-collision blocks 5 and anti-collision covers 6 are provided to protect the welding point 23. The silicone grip sleeve 3 and the inner core 1 are glued together. The flexible heating element 2 and the inner core 1 are axially positioned by positioning blocks 15 and positioning grooves 21. The flexible heating element 2 and the inner core 1 are bonded together by adhesive. The anti-collision blocks 5 and the inner core 1, and the anti-collision blocks 5 and the anti-collision covers 6 are connected by snap-fit ​​connections.
