Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lighting, and particularly relates to an electric assist bicycle lighting lamp. Background Art

[0002] A bicycle lighting lamp is a device installed on a bicycle and is used to provide lighting at night or in low visibility conditions. It usually includes a front lamp and a rear lamp. The front lamp is used to illuminate the road ahead, and the rear lamp is used to make other road users notice the presence of the bicycle. The lighting lamp can be powered by a battery or generate electricity through the rotation of the bicycle wheel.

[0003] For traditional bicycle lighting lamps, it is inconvenient to adjust the angle after installation and fixation. Even if some lighting lamps can be adjusted for angle rotation, due to the lack of an anti-rotation function in common rotating devices, self-rotation may occur during the bumpy driving of the vehicle, resulting in the deviation of the lighting lamp angle and being unfavorable for use. Therefore, it is necessary to develop an electric assist bicycle lighting lamp. Content of the Utility Model

[0004] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Simplifications or omissions may be made in this part, as well as in the abstract of the specification and the title of the utility model of this application, to avoid obscuring the purpose of this part, the abstract of the specification, and the title of the utility model. However, such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] To solve the above technical problems, according to one aspect of the utility model, the following technical solutions are provided by the utility model:

[0006] An electric assist bicycle lighting lamp, which includes:

[0007] A mounting bracket. The bottom of the inverted "U" - shaped mounting bracket is provided with a "冂" - shaped bottom frame. The center of the inner bottom wall of the bottom frame is rotatably provided with a vertical hollow cylinder through a bearing seat, and a lamp body is arranged on one side of the cylinder;

[0008] A driving mechanism, which is arranged on the cylinder and used to drive the cylinder to rotate. The driving mechanism includes a vertical pull rod that slidably penetrates through the center of the top wall of the inner cavity of the cylinder. The lower end of the pull rod is provided with a vertical spline rod. The upper half of the inner cavity of the cylinder is provided with a spline groove adapted to the spline rod, and the upper end of the pull rod is provided with a pull plate;

[0009] The anti-rotation mechanism is arranged on the mounting frame for locking the rotation of the cylinder, and includes a circular opening opened in the center of the bottom wall of the mounting frame. The inner side wall of the opening is surrounded by a second spring with the cylinder as the center. The other end of each second spring is provided with a friction plate that squeezes the side wall of the cylinder. The rod body of the cylinder is located below the friction plate and is slidably provided with a lifting ring. A vertical connecting rod is fixed between the top of the lifting ring and the bottom wall of the pull plate.

[0010] As a preferred solution of the electric-assisted bicycle lighting lamp described in the utility model, the gap in the outer wall of the cylinder passes through the opening and the top wall of the mounting bracket, and an indicator mark is provided at the upper end of the cylinder, the orientation of the indicator mark is consistent with the orientation of the lamp body, and an angle marking line is provided around the indicator mark at the top of the mounting bracket.

[0011] As a preferred solution of the electric-assisted bicycle lighting lamp described in the utility model, at least four mounting holes are formed on the outer side wall of the mounting frame.

[0012] As a preferred solution of the electric-assisted bicycle lighting described in the utility model, the diameter of the spline rod is larger than the diameter of the pull rod and a vertical first spring is fixedly arranged between the top wall of the spline rod and the inner top wall of the cylinder, and the gap in the shaft of the pull rod passes through the coil of the first spring.

[0013] As a preferred solution of the electric-assisted bicycle lighting described in the utility model, the length of the cylinder is at least twice the length of the spline rod, and a gap is set between the lower half of the inner cavity of the cylinder and the outer side wall of the spline rod.

[0014] As a preferred solution of the electric-assisted bicycle lighting lamp described in the utility model, the outer surface and edge of the lifting ring and the lower edge of the friction plate are smooth and arc-shaped.

[0015] The beneficial effects of the utility model are:

[0016] 1. When the angle of the lamp body needs to be adjusted, the user can pull the pull plate upwards, and the pull rod and spline rod rise. The spline rod rises and is located in the upper half of the inner cavity of the cylinder. At the same time, the lifting ring rises through the connecting rod. The lifting ring replaces the cylinder to press against the friction plate, so that the friction plate no longer exerts pressure on the cylinder, facilitating the rotation of the cylinder, the lamp body and the indicator mark. The angle mark line can be used to understand the adjustment of the lamp body angle.

[0017] 2. After the adjustment is completed, release the push plate, the spline rod and the lifting ring drop down, and the lifting ring drops to the bottom of the friction plate. At this time, the second spring pushes the friction plate to squeeze on the outer wall of the cylinder, improving the stability of the cylinder and preventing it from rotating.

[0030] In order to make the purpose, technical solution and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the attached drawings.

[0031] Please refer to Figure 1-Figure 7 , which shows a schematic structural diagram of an embodiment of an electric assist bicycle lighting lamp of the present utility model. Please refer to Figure 1-Figure 7 , and a detailed introduction to an electric assist bicycle lighting lamp will be given.

[0032] An electric assist bicycle lighting lamp includes a mounting bracket 100. A bottom frame 101 in the shape of a reversed "U" is provided at the bottom of the mounting bracket 100. A vertical hollow cylinder 103 is rotatably provided at the center of the inner bottom wall of the bottom frame 101 through a bearing seat 102. A lamp body 104 is provided on one side of the cylinder 103;

[0033] A driving mechanism 200 is provided on the cylinder 103 for driving the cylinder 103 to rotate, including a vertical pull rod 201 that slides through the center of the top wall of the inner cavity of the cylinder 103. A vertical spline rod 202 is provided at the lower end of the pull rod 201. A spline groove 203 adapted to the spline rod 202 is provided in the upper half of the inner cavity of the cylinder 103. A pull plate 205 is provided at the upper end of the pull rod 201;

[0034] An anti-rotation mechanism 300 is provided on the mounting bracket 100 for locking the self-rotation of the cylinder 103, including a circular opening 301 opened at the center of the bottom wall of the mounting bracket 100. A second spring 302 is arranged around the inner side wall of the opening 301 with the cylinder 103 as the center. The other end of each second spring 302 is provided with a friction plate 303 that presses against the side wall of the cylinder 103. A lifting ring 304 is slidably arranged on the rod body of the cylinder 103 below the friction plate 303. A vertical connecting rod 305 is fixedly arranged between the top end of the lifting ring 304 and the bottom wall of the pull plate 205;

[0035] The outer wall gap of the cylinder 103 passes through the opening 301 and the top wall of the mounting bracket 100, and an indicator mark 105 is provided on the upper end of the cylinder 103. The orientation of the indicator mark 105 is consistent with the orientation of the lamp body 104. An angle marking line 106 is provided around the top of the mounting bracket 100. When the cylinder 103 drives the lamp body 104 to adjust its orientation, the indicator mark 105 rotates accordingly, and the angle marking line 106 can be used to understand the degree of angle adjustment of the lamp body 104.

[0036] The outer wall of the mounting frame 100 is provided with at least four mounting holes 107 , and the device can be conveniently mounted on a vehicle by bolts adapted to the mounting holes 107 ;

[0037] Among them: the diameter of the spline rod 202 is larger than the diameter of the pull rod 201 and a vertical first spring 204 is fixedly arranged between the top wall of the spline rod 202 and the inner top wall of the cylinder 103. The gap of the rod body of the pull rod 201 passes through the circle of the first spring 204. When the pull plate 205 is not pulled, the first spring 204 will push the spline rod 202 so that the spline rod 202 is located in the lower half of the inner cavity of the cylinder 103.

[0038] The length of the cylinder 103 is at least twice the length of the spline rod 202. A gap is set between the lower half of the inner cavity of the cylinder 103 and the outer wall of the spline rod 202. When the pull plate 205 is pulled upward, the pull rod 201 and the spline rod 202 rise, and the spline rod 202 rises to the upper half of the inner cavity of the cylinder 103. At this time, rotating the pull plate 205 can drive the cylinder 103 to rotate.

[0039] Among them: the outer surface and edge of the lifting ring 304 and the lower edge of the friction plate 303 are smooth and arc-shaped. When the cylinder 103 needs to be rotated, after pulling the pull plate 205 upward, the lifting ring 304 is lifted up at the same time through the connecting rod 305. Since the upper edge of the lifting ring 304 and the lower edge of the friction plate 303 are smooth and arc-shaped, it is convenient for the lifting ring 304 to rise into the inner side of all the friction plates 303, thereby replacing the cylinder 103 to press against the friction plate 303, so that the friction plate 303 no longer exerts pressure on the cylinder 103, thereby facilitating the rotation of the cylinder 103.

[0040] During use, when the angle of the lamp body 104 needs to be adjusted, the user can pull the pull plate 205 upwards, and the pull rod 201 and the spline rod 202 rise. The spline rod 202 rises and is located in the upper half of the inner cavity of the cylinder 103. At the same time, the lifting ring 304 rises through the connecting rod 305. The lifting ring 304 replaces the cylinder 103 to press against the friction plate 303, so that the friction plate 303 no longer applies pressure to the cylinder 103, making it easier for the cylinder 103, the lamp body 104 and the indicator mark 105 to rotate. The angle mark line 106 can be used to understand how much the angle of the lamp body 104 has been adjusted.

[0041] After the adjustment is completed, the pressing plate 205 is released, the spline rod 202 and the lifting ring 304 descend, and the lifting ring 304 descends to the bottom of the friction plate 303. At this time, the second spring 302 pushes the friction plate 303 to be squeezed on the outer wall of the cylinder 103, thereby improving the stability of the cylinder 103 and preventing it from rotating.

[0042] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
