Description

Technical Field

[0001] The utility model relates to the technical field of electric motorcycles, in particular to a large guard bar for two-wheeled electric motorcycles. Background Art

[0002] The large bumper, also known as a protective bar, on two-wheeled electric motorcycles is primarily used to protect the rider and motorcycle from damage in the event of a fall or accidental collision. It's common for two-wheeled electric motorcycles to have large bumpers installed on their exteriors, and their designs are generally similar. A complete bumper set typically consists of a front bumper, a front connecting pipe, left and right small bumpers, a rear rack, a rear connecting pipe, and pedals.

[0003] The existing large guard bars of two-wheeled electric motorcycles have the following main problems: 1. The large guard bar of the vehicle is covered on the outside of the plastic part. Therefore, when the vehicle needs to be repaired and the front panel plastic part is removed, the front surrounding pipe part of the large guard bar must be removed first. The fixing bolts of the front surrounding pipe are hidden inside the foot pedal plastic part. Only after the foot pedal plastic part is removed can the front surrounding pipe part of the large guard bar be removed, which increases the difficulty and working hours of maintenance. 2. The connection structure between the various components of the large guard bar is complicated and unsightly, and the locking force is difficult to control. Excessive locking force can easily cause deformation of the pipe fittings, and too little locking force will cause looseness, and the connected components will rub against each other during bumpy driving, producing abnormal noise. 3. The actual load-bearing capacity of the pedal part is small, and it is easy to cause deformation and damage to the pedal support part after long-term use. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0028] Example 1

[0029] Figure 1-6 The first embodiment of a large guard bar for a two-wheeled electric motorcycle is shown. Figure 1 、 2 As shown, it includes a front connecting pipe 1, a first front surround pipe 2, a second front surround pipe 3, a small bumper 4, a rear connecting pipe 5, a rear rack 6, and a front footrest 7. The front connecting pipe 1, the first front surround pipe 2, the second front surround pipe 3, the small bumper 4, and the rear connecting pipe 5 are connected in sequence. The rear rack 6 is connected to the upper ends of the rear connecting pipe 5 and the small bumper 4, and the front footrest 7 is connected to the second front surround pipe 3.

[0030] like Figure 3 、 4 As shown, a bushing 8 is provided at the connection between the first front enclosure tube 2 and the second front enclosure tube 3, and two welding holes 9 are provided on the second front enclosure tube 3. The second front enclosure tube 3 is first welded to the lower end of the bushing 8 through the welding holes 9. The upper end of the bushing 8 is inserted into the first front enclosure tube 2 and the bushing 8 is provided with a threaded hole 10. A through hole 11 is provided at the position corresponding to the threaded hole 10 on the side of the first front enclosure tube 2. The fastener is a fastening bolt 12. The upper end of the bushing 8 is inserted into the first front enclosure tube 2, and the fastening bolt 12 passes through the through hole 11 and is threadedly connected to the threaded hole 10. Because the gap between the outer diameter of the bushing 8 and the inner diameter of the first front enclosure tube 2 is very small, when the fastening bolt 12 is screwed in, the first front enclosure tube 2 can only be deformed to fit onto the bushing 8 at most, and cannot be squeezed in any further. Even if the locking force is large, the first front enclosure tube 2 will not be squeezed and deformed.

[0031] like Figure 5 As shown, the front footrest 7 includes a pedal 71, a fixing plate 72, and a tension spring 73. The fixing plate 72 is fixedly connected to the second front surround tube 3. The pedal 71 is hinged to the fixing plate 72 by a rivet 74. One end of the tension spring 73 is connected to the fixing plate 72, and the other end is connected to the pedal 71. A flange 75 is provided at the bottom of the fixing plate 72. When the pedal 71 is opened with the rivet 74 hinge point as the rotation axis, the lower edge of the pedal 71 will abut against the flange 75, and the load that can be sustained is greatly increased. When the pedal 71 is subjected to force, it is not easy to bend and deform the fixing plate 72.

[0032] like Figure 6 As shown, it also includes a rear footrest 13, which is connected to the small guardrail 4 through a fixed bracket 14 and can be freely and flexibly disassembled or installed for use according to the needs of different scenarios.

[0033] Example 2

[0034] Figure 7 As shown, the bushing 8 is provided with an opening 81 along the axial direction, and a notch 31 is provided at the end of the second front enclosure tube 3. The bushing 8 is inserted into the second front enclosure tube 3, and the first front enclosure tube 2 is inserted into the bushing 8. The locking member includes a pipe clamp 15 and a locking screw 16. The pipe clamp 15 is sleeved on the second front enclosure tube 3, and the locking screw 16 is threadedly connected to the pipe clamp 15. The locking screw 16 can change the inner diameter of the pipe clamp 15 and lock the second front enclosure tube 3, bushing 8 and first front enclosure tube 2. The end of the first front enclosure tube 2 is a variable diameter structure, with its small diameter end inserted into the bushing 8 and its large diameter end abutting against the bushing 8. The bushing 8 is a nylon bushing.

[0035] During installation, first insert the bushing 8 into the second front surround tube 3, then pre-install the locking screw 16 and the pipe clamp 15 on the second front surround tube 3. Do not tighten it first, and insert the small diameter end of the lower end of the first front surround tube 2 into the bushing 8. The first front surround tube 2 is limited by the bushing 8 by changing its diameter. Finally, tighten the locking screw 16. The bushing 8 has an opening 81 on the side, and the second front surround tube 3 has a cutout 31. After tightening, the deformation of these three parts is used to firmly clamp the first front surround tube 2, thereby achieving the locking function of the first front surround tube 2 and the second front surround tube 3. Because the bushing 8 is added, direct contact between the first front surround tube 2 and the second front surround tube 3 is avoided, preventing them from rubbing and producing abnormal noise during bumpy driving. At the same time, the nylon material has a smooth surface and is self-lubricating, low noise, high mechanical strength, wear resistance and pressure resistance, which can further ensure that no abnormal riding noise is generated and the reliability of the structure is ensured.

[0036] The remaining structures of the large guard bar are the same as those of the first embodiment.

[0037] The above specific implementation methods are only for illustrating the technical concept and structural features of the utility model, and the purpose is to enable relevant persons familiar with this technology to implement them accordingly. However, the above content does not limit the scope of protection of the utility model. Any equivalent changes or modifications made based on the spirit of the utility model should fall within the scope of protection of the utility model.
