Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, specifically a replaceable stable speed regulating core that can be matched with the outer skin of the handlebars of an electric vehicle. Background Technology

[0002] Electric bicycles are an important mode of transportation for residents' short-distance travel. Users can adjust the speed by twisting the handlebars. With the development of related technologies, third parties offer customized outer covers, such as rubber covers or heated covers, for users to choose from. Replacing the original cover with this new cover achieves the same effect. However, the original speed control core is generally irregular in shape and size, resulting in poor compatibility between the third-party cover and the original speed control core. For relevant technicians, the challenge is to provide a speed control core that can both replace the original speed control core and... A shape that can be adapted to third-party outer covers is a desirable solution. The core issue of this solution is how to ensure the stability of the new inner core itself and its connection with the handlebars, thereby ensuring speed adjustment accuracy, and how to make the new inner core compatible with button assemblies of different diameters. Given this situation, how to provide a speed adjustment inner core that can maintain stability in itself and its connection with the handlebars, thereby ensuring speed adjustment accuracy, and how to make the speed adjustment inner core compatible with button assemblies of different diameters, has become an increasingly urgent problem for relevant technical personnel to solve. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a replaceable stable speed regulating core that can be matched with the outer skin of the handlebars of electric bicycles.

[0004] A replaceable, stable speed-regulating inner core that can be used with the handlebar cover of an electric bicycle includes a main cover, a secondary cover, and a grip. The main cover has a Hall sensor located on its lower inner side. The grip includes a connecting part and a holding part. The connecting part is located inside the main cover and the secondary cover. An arc-shaped magnet is located at the lower part of the connecting part, above the Hall sensor. The holding part penetrates the secondary cover. The main cover has a screw hole at its lower inner side. The secondary cover has a screw at its lower side, which is threaded into the screw hole. The main cover has a first slot at its upper inner side. The secondary cover has a buckle at its upper inner side, which engages with the first slot.

[0005] Furthermore, a slider is provided inside the main cover, and a slide is provided on the edge of the connecting part near the secondary cover. The slide is located on the side of the slider away from the secondary cover, and the slide is slidably connected to the slider.

[0006] Furthermore, the main cover is symmetrically provided with connecting plates on the side away from the secondary cover, and the connecting plates are provided with protrusions on the side away from the secondary cover. The main cover is provided with a clamp on the side away from the secondary cover, and the clamp is symmetrically provided with recesses on its inner side. The clamp is sleeved with the connecting plate, and the recesses are engaged with the protrusions. The clamp has an opening at the bottom, and a bolt is provided at the bottom of the clamp. The bolt is threaded to both sides of the opening of the clamp.

[0007] Furthermore, the center of the recess is offset from the middle position of the clamp axially.

[0008] Furthermore, a spring is provided between the main cover and the connecting part. The spring includes a plug-in end and a snap-fit ​​end. A plug hole is provided inside the main cover. A second slot is provided on the side of the connecting part near the main cover. The plug-in end is plugged into the plug hole, and the snap-fit ​​end is snapped into the second slot.

[0009] Furthermore, a glue-filling port is provided through the sub-cover at the position corresponding to the Hall sensor.

[0010] Furthermore, a main fixing position is provided at the lower part of the main cover, and a secondary fixing position is provided at the lower part of the secondary cover. The main fixing position and the secondary fixing position form a limiting hole. A wire is provided at the lower part of the Hall sensor, and the wire is led out through the limiting hole.

[0011] The beneficial effects of this utility model of a replaceable stable speed regulating core that can be used with the outer skin of an electric bicycle handlebar are as follows:

[0012] 1. The corresponding arrangement of the arc-shaped magnet and the Hall sensor provides a good structural foundation for the speed regulation function of this speed regulation core;

[0013] 2. The screw is connected to the screw hole thread and the buckle is engaged with the first slot. The double connection design effectively ensures the stability of the connection between the main cover and the secondary cover. The slide is located on the side of the slider away from the secondary cover and is slidably connected to the slider, which effectively ensures the stable sliding limit of the grip sleeve. In this way, the speed regulating core itself can remain stable.

[0014] The clamp and connecting plate are fitted together, and the recess and protrusion are engaged, which effectively ensures the stability of the connection between the clamp and the main cover. The bolt and the clamp opening are threaded on both sides. Users only need to tighten the bolt to make the connecting plate fit with the handlebar. If it is loose, just tighten the bolt again, which effectively ensures the stability of the connection between this speed control core and the handlebar.

[0015] With the above improvements, the speed control core itself and its connection with the handlebars can remain stable, thus effectively ensuring speed control accuracy.

[0016] 3. The center of the recess is offset from the middle position of the clamp axis, which allows for two ways to connect the clamp and the connecting plate. The difference between the two is whether there is a gap between the clamp and the main cover. The car manufacturer can decide whether there is a gap based on the diameter of the button assembly. This speed control core can meet the requirements of both diameter button assemblies, effectively ensuring the compatibility of this speed control core with button assemblies of different diameters.

[0017] 4. The glue filling port provides a good structural foundation for glue filling. After the glue is filled, the Hall sensor position is sealed, which effectively ensures the waterproofness of this speed control core. Attached Figure Description

Detailed Implementation

[0027] To make the description clearer, the replaceable stable speed regulating core of this utility model, which can be used with the outer skin of the handlebars of electric bicycles, will be further described in conjunction with the accompanying drawings.

[0028] A replaceable, stable speed-regulating inner core that can be used with the handlebar cover of an electric bicycle includes a main cover 3, a secondary cover 4, and a grip sleeve 1. The main cover 3 has a Hall sensor 16 disposed on its lower inner side. The grip sleeve 1 includes a connecting part 12 and a gripping part 13. The connecting part 12 is located inside the main cover 3 and the secondary cover 4. An arc-shaped magnet 14 is disposed at the lower part of the connecting part 12, and the arc-shaped magnet 14 is located above the Hall sensor 16. The gripping part 13 penetrates the secondary cover 4. The main cover 3 has a screw hole 18 disposed on its lower inner side. The secondary cover 4 has a screw 26 disposed at its lower side, and the screw 26 is threadedly connected to the screw hole 18. The main cover 3 has a first slot 20 disposed on its upper inner side. The secondary cover 4 has a buckle 27 disposed on its upper inner side, and the buckle 27 engages with the first slot 20.

[0029] Furthermore, a slider 19 is provided inside the main cover 3, and a slide 11 is provided on the edge of the connecting part 12 near the side of the secondary cover 4. The slide 11 is located on the side of the slider 19 away from the secondary cover 4, and the slide 11 is slidably connected to the slider 19.

[0030] Furthermore, a connecting plate 22 is symmetrically arranged on the side of the main cover 3 away from the secondary cover 4, and a protrusion 21 is provided on the side of the connecting plate 22 away from the secondary cover 4. A clamp 2 is provided on the side of the main cover 3 away from the secondary cover 4, and recesses 7 are symmetrically arranged on the inner side of the clamp 2. The clamp 2 is sleeved with the connecting plate 22, and the recesses 7 are engaged with the protrusions 21. The clamp 2 has an opening at the bottom, and a bolt 6 is provided at the bottom of the clamp 2. The bolt 6 is threadedly connected to both sides of the opening of the clamp 2.

[0031] Furthermore, the center of the recess 7 is offset from the center position of the clamp 2 in the axial direction.

[0032] Furthermore, a spring 8 is provided between the main cover 3 and the connecting part 12. The spring 8 includes an insertion end 9 and a snap-fit ​​end 10. An insertion hole 15 is provided inside the main cover 3. A second slot 23 is provided on the side of the connecting part 12 near the main cover 3. The insertion end 9 is inserted into the insertion hole 15, and the snap-fit ​​end 10 is snapped into the second slot 23.

[0033] Furthermore, the sub-cover 4 and the Hall sensor 16 are respectively provided with a glue-filling port 24.

[0034] Furthermore, a main fixing position 17 is provided at the lower part of the main cover 3, and a secondary fixing position 25 is provided at the lower part of the secondary cover 4. The main fixing position 17 and the secondary fixing position 25 form a limiting hole. A wire 5 is provided at the lower part of the Hall sensor 16, and the wire 5 is led out through the limiting hole.

[0035] The working principle of this utility model of a replaceable stable speed regulating core that can be used with the outer skin of an electric bicycle handlebar is as follows: Adhesive is injected into the mounting position of the Hall sensor 16 through the glue inlet 24. It should be further explained that when the diameter of the button assembly is larger than the outer diameter of the clamp 2, there needs to be no gap between the clamp 2 and the main cover 3. When the diameter of the button assembly is larger than the outer diameter of the connecting plate 22 but smaller than the outer diameter of the clamp 2, there needs to be a gap between the clamp 2 and the main cover 3. Assuming this is a large-diameter button assembly, the clamp 2 is positioned closer to the main cover 3 on the side away from the recess 7, and the clamp 2 is fitted around the connecting plate 22, so that the recess 7 and the protrusion 21 engage. At this time, there is no gap between the clamp 2 and the main cover 3, thus enabling the speed regulation function to operate smoothly. The inner core is inserted into the handlebars of the electric bicycle. When the whole assembly is moved to the designated position, the bolt 6 is tightened. At this time, the connecting plate 22 fits tightly with the handlebars and there will be no undue positional displacement. When the user rides, he / she holds and rotates the grip part 13, which makes the connecting part 12 rotate relative to the main cover 3. Correspondingly, the arc magnet 14 rotates relative to the Hall sensor 16, thus adjusting the speed. The spring 8 is in a tightened state at this time. When the grip part 13 is released, the spring 8 automatically returns to the relaxed state and drives the connecting part 12, the grip part 13, and the grip sleeve 1 back to their original positions, thus gradually reducing the speed. During this process, the slider 19 always maintains the sliding limit on the slide table 11, so that the rotation of the grip sleeve 1 remains stable.

[0036] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
