Description

Technical Field

[0001] This utility model relates to the field of electric bicycle technology, and in particular to an integrated handlebar structure for electric bicycles. Background Technology

[0002] Electric bicycles, as a green and convenient means of transportation, are one of the mainstream modes of transportation for short-distance commuting and daily travel in cities. The handlebar structure is not only the core of control, but also an important part of the overall appearance and user experience of the vehicle.

[0003] Currently, most electric bicycles on the market use external wiring harnesses for their power cords, brake signal wires, and light control wires. This not only severely affects the clean appearance of the entire vehicle, but the wiring harnesses are also prone to aging and damage due to friction with external objects, scratches, or long-term exposure to sun and rain, posing safety hazards. Although some models have attempted to improve the appearance by using partially embedded or semi-hidden wiring, this has brought new challenges to maintainability. Since the wiring harnesses run through the internal structure of the handlebars or front fork, once a fault occurs, repair personnel often need to disassemble the entire handlebar assembly or even part of the front fork structure. The operation process is complex and time-consuming, causing considerable inconvenience to users' daily maintenance and professional repairs. Based on this, an integrated handlebar structure for electric bicycles is proposed here. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model proposes an integrated handlebar structure for electric bicycles.

[0005] The technical solution of this utility model is implemented as follows: an integrated handlebar structure for an electric bicycle, comprising a handlebar body and a connecting rod, wherein a second connecting beam is fixedly connected to the top end of the connecting rod, a first connecting beam connects the second connecting beam and the handlebar body, and the connecting rod is axially hollow, further comprising:

[0006] Storage frame, fixed to the connecting rod;

[0007] The clamping hook is detachably and vertically penetrates the storage frame, and the inner end of the clamping hook has a hook portion located inside the connecting rod, and the clamping hook also has a pressure block that can be moved close to or away from the hook portion.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4As shown, an integrated handlebar structure for an electric bicycle includes a handlebar body 1 and a connecting rod 4. The handlebar body 1 has an arc-shaped structure with slightly curved ends. The arc is ergonomically optimized to perfectly match the rider's natural grip posture, reducing wrist fatigue during long rides. Both ends of the handlebar body 1 are equipped with grips 5, which are made of highly elastic, non-slip rubber material. A high-density sponge pad is embedded inside, and the outer rubber surface is pressed with non-slip textures. This not only improves friction during gripping and prevents the grips from slipping due to sweaty hands during riding, but also allows for better gripping performance. The cushioning effect of the cotton padding layer reduces the force of road vibration transmitted to the hand. In addition, the connection between the grip 5 and the handlebar body 1 adopts an interference fit, and high-strength anaerobic adhesive is applied to the mating area to ensure that the grip 5 will not loosen during long-term use, and at the same time facilitates disassembly and replacement during later maintenance. The connecting rod 4 is used to connect with the electric bicycle front fork assembly. The connecting rod 4 is made of thickened stainless steel tubing, and its axial direction is hollow. The inner diameter of the hollow part is precisely calculated to accommodate the electric bicycle's main wiring harness (including power line, brake signal line, light control line, etc.) to pass through. The outer surface of the connecting rod 4 is treated with electrophoretic rust prevention, which can effectively resist the erosion of external environmental factors such as rain and dust, and extend its service life. The handlebar body 1 is also hollow inside, and a cable pass-through port is opened on the outside of the handlebar body 1. A second connecting beam 3 is fixedly connected to the top of the connecting rod 4. Guide holes 9 are opened at both ends of the second connecting beam 3. A first connecting beam 2 is connected between the second connecting beam 3 and the handlebar body 1. The handlebar body 1, the first connecting beam 2, the second connecting beam 3 and the connecting rod 4 can be fixed by welding. In addition, it also includes The device includes a storage frame 6 and a clamping hook 10. The storage frame 6 is fixed to the connecting rod 4, specifically located at the upper end of the outer wall of the connecting rod 4. The clamping hook 10 is detachably perpendicularly penetrating the storage frame 6, and the inner end of the clamping hook 10 has a hook part 105 located inside the connecting rod 4. The hook part 105 can pull out the internal wire harness of the connecting rod 4, which is convenient for pulling out for maintenance. The clamping hook 10 also has a pressure block 107 that can be close to or away from the hook part 105. The pressure block 107 can press down the internal wire harness of the connecting rod 4 to prevent accidental contact and pulling movement.

[0026] Among them, see Figure 1 and Figure 2 As shown, the second connecting beam 3 has an opening that passes through the interior of the connecting rod 4. A protruding ring 7 is fixed at the opening, and a rubber ring 8 is fixed on the inner wall of the protruding ring 7. The wire harness passes through the protruding ring 7 after exiting the connecting rod 4, and the opening of the protruding ring 7 is sealed by the rubber ring 8. Alternatively, a conduit can be connected between the second connecting beam 3 and the handlebar body 1 so that the wire harness passes through the conduit and enters the handlebar body 1.

[0027] See Figure 2 and Figure 3As shown, a storage groove 61 is provided on the upper surface of the storage frame 6, and an opening 41 is provided on the connecting rod 4. Under normal conditions, a mobile phone can be placed in the storage groove 61, and grooves can be opened at both ends of the upper surface of the storage frame 6 so that bags can be hooked.

[0028] See Figure 2 and Figure 4 As shown, the clamping hook part 10 also includes a support plate 101. A groove 104 is provided between the support plate 101 and the hook part 105. A pressure block 107 is provided in the groove 104, and a threaded rod 106 is installed on the pressure block 107 through a bearing seat. The threaded rod 106 screws through the support plate 101. A screwing block is installed at the outer end of the threaded rod 106. A sealing plate 102 is fixed at the outer end of the support plate 101. Rubber pads 103 are fixed at both ends of the sealing plate 102 facing the support plate 101. The upper and lower ends of the rubber pads 103 are provided with protrusions. The protrusions protrude outward from the outer wall of the storage frame 6 for the groove for the support plate 101 to enter. The stability of the support plate 101 after installation can be improved by friction and compression. In order to further increase the stability, screw holes can be opened on the sealing plate 102, and then screws can be used for further tightening.

[0029] As described above, during wiring, the harness can be routed inside the connecting rod 4 and the handlebar body 1. This embedded wiring method minimizes the exposed area of ​​the harness in the external environment. On the one hand, it avoids friction and scratches between the harness and external objects due to long-term exposure, effectively reducing the risk of damage to the harness sheath and breakage of internal wires, and significantly improving the protection of the harness. On the other hand, the embedded design makes the overall structure of the handlebar more concise and neat, eliminating the messiness caused by exposed harnesses and improving the aesthetics of the product. The harness passes through the groove 104. After wiring is completed, the threaded rod 106 can be rotated to move the pressure block 107 inward to press down on the harness, effectively limiting the displacement of the harness within the groove 104. Even if the wire is accidentally pulled during use, it can prevent the harness from detaching from the groove 104, the connecting rod 4, or the internal channel of the handlebar body 1, ensuring the stability of the harness connection and reducing equipment failures caused by harness detachment.

[0030] When it is necessary to inspect and maintain the wiring harness inside the connecting rod 4, the screw block can be used to pull the threaded rod 106 outward to move the support plate 101 outward. The hook part 105 integrated on the support plate 101 has formed a stable connection with the wiring harness inside the connecting rod 4 under normal conditions. The contact part of the hook part 105 with the wiring harness is the connection node of the wiring harness (such as plugs, connectors and other key connection parts). As the support plate 101 moves outward, the hook part 105 will pull the wiring harness outward, gradually pulling the wiring harness that was originally hidden inside the connecting rod 4 outward. The staff can directly inspect, repair or replace the connection part of the pulled-out wiring harness and the surrounding wires.

[0031] It should be noted that the hook part 105 corresponds to the wire harness part as the connection node of the wire harness. Under normal conditions, the closed structure of the connecting rod 4 can provide a good protective environment for the wire harness connection part, isolate the intrusion of external dust, moisture, impurities and other pollutants, and avoid problems such as poor contact, oxidation and corrosion of the connection node part due to moisture and dust accumulation, thereby further ensuring the reliability and service life of the wire harness connection.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
