Description

Technical Field

[0001] This utility model relates to the field of bicycle accessories technology, specifically to a support device for the instrument panel of an electric-assisted bicycle. Background Technology

[0002] Electric-assist bicycles (EMBs) are a new type of transportation that uses batteries as an auxiliary power source, is equipped with a motor, and features a power assistance system. They integrate human-powered riding with motor-assisted propulsion. In the ESB category, the centrally mounted motor is connected to the frame and transmits power via a chain to the rear wheel. Pedals are mounted on both sides of the motor, allowing the rider to pedal even when the motor is not powered.

[0003] To facilitate installation, most existing digital instruments use brackets for quick mounting. However, current brackets are all clamp-type, and their inner diameter is fixed after installation, which is not conducive to installation on bicycle frames of different sizes and reduces the feasibility of bracket installation. Therefore, there is a need to develop a support device for electric bicycle instruments. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0006] An instrument support device for an electric-assist bicycle, comprising:

[0007] The support base has grooves staggered on both sides of its bottom. A transverse rotating rod is rotatably mounted on each of the grooves on both sides. Each rotating rod has a clamp for self-locking and clamping the frame.

[0008] The control box is fixedly mounted on the right end of the support base. The right ends of the two rotating rods extend into the interior of the control box and are respectively equipped with gears. The two gears mesh with each other for transmission. One of the rotating rods is longer than the other. A worm gear is fixedly mounted on the shaft of the longer rotating rod. The worm gear is located in the inner cavity of the control box. A follower rod perpendicular to the rotating rod is mounted on the inner wall of the control box above the rotating rod. A worm gear meshing with the worm gear is mounted on the shaft of the follower rod. A drive rod parallel to the follower rod is rotatably mounted on the inner wall of the control box through a bearing seat. A first speed-up gear is fixedly mounted on the shaft of the follower rod. A second speed-up gear meshing with the first speed-up gear is fixedly mounted on the shaft of the drive rod. The diameter of the second speed-up gear is larger than the diameter of the first speed-up gear.

[0009] In a preferred embodiment of the instrument support device for an electric-assisted bicycle described in this utility model, each of the rotating rods has multiple clamps, and the multiple clamps are staggered from each other.

[0010] As a preferred embodiment of the instrument support device for an electric-assisted bicycle described in this utility model, the clamps on each of the rotating rods are in the shape of a "" and a mirror "", and the concave surface of the clamps is provided with anti-slip texture.

[0011] As a preferred embodiment of the instrument support device for electric-assisted bicycles described in this utility model, the support base is provided with mounting plates fixedly on both upper edges, and the mounting plates are provided with screw holes. The outer shell of the instrument is provided with a fixing plate corresponding to the mounting plate, and the fixing plate is provided with mounting holes for aligning with the mounting plate.

[0012] In a preferred embodiment of the instrument support device for an electric-assisted bicycle described in this utility model, the lead angle of the worm is smaller than the equivalent friction angle between the meshing teeth of the worm wheel, thereby achieving reverse self-locking. The worm wheel can only be driven to rotate by the worm, and the worm wheel cannot drive the worm.

[0013] As a preferred embodiment of the instrument support device for an electric-assisted bicycle described in this utility model, one end of the drive rod extends and rotatably penetrates the side wall of the control box, and an anti-slip knob is fixedly provided at the end, with anti-slip texture provided on the outer side of the anti-slip knob.

[0014] The beneficial effects of this utility model are as follows: the clamps on both sides are placed on the rod body of the frame that needs to be fixed. The drive rod is rotated by the anti-slip knob. After the follower rod is accelerated by the second and first speed-up gears, the worm and worm wheel are driven to rotate. This causes the rotating rod to drive one gear to rotate and the other gear to rotate in the opposite direction. This causes the clamps on both sides to gradually move closer to the rod body until the rod body is clamped. This allows for the clamping and installation of rod bodies of different sizes. Furthermore, because the worm and worm wheel have self-locking properties, only the worm can drive the worm wheel, and the worm wheel cannot drive the worm. This makes the clamps on both sides more stable when holding the rod body. Attached Figure Description

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figures 1-5 The diagram shown is a structural schematic of an embodiment of the instrument support device for an electric-assisted bicycle according to this utility model. Please refer to [link / reference]. Figures 1-5 This paper provides a detailed description of an instrument support device for electric-assisted bicycles.

[0027] An instrument support device for an electric-assisted bicycle includes a support base 100. The bottom of the support base 100 has grooves 101 staggered on both sides. The grooves 101 on both sides are respectively rotatably provided with transverse rotating rods 102. Each rotating rod 102 is provided with a clamping plate 103 for self-locking and clamping the frame.

[0028] A control box 200 is fixedly mounted on the right end of the support base 100. The right ends of the two rotating rods 102 extend into the interior of the control box 200 and are respectively equipped with gears 201. The two gears 201 mesh with each other for transmission. One of the rotating rods 102 is longer than the other. A worm gear 204 is fixedly mounted on the shaft of the longer rotating rod 102. The worm gear 204 is located in the inner cavity of the control box 200. A follower rod 202, perpendicular to the rotating rod 102, is mounted on the inner wall of the control box 200 above the rotating rod 102. A worm 203, which meshes with the worm gear 204, is mounted on the shaft of the follower rod 202 for transmission. The inner wall of the control box 200 is rotatably mounted via a bearing seat. A drive rod 206 parallel to the follower rod 202 is provided. A first speed-boosting gear 205 is fixedly mounted on the body of the follower rod 202, and a second speed-boosting gear 207 meshing with the first speed-boosting gear 205 is fixedly mounted on the body of the drive rod 206. The diameter of the second speed-boosting gear 207 is larger than the diameter of the first speed-boosting gear 205. Since the worm gear 204 and the worm 203 are a reduction mechanism with a large reduction ratio, if the worm gear 203 directly drives the worm wheel 204 to rotate, the user needs to drive the follower rod 202 to rotate many times. Therefore, the larger diameter second speed-boosting gear 207 drives the smaller diameter first speed-boosting gear 205 to rotate, and then drives the follower rod 202 to rotate, thus making it convenient for the user to drive the follower rod 202 to rotate.

[0029] The rotating rod 102 has multiple clamping plates 103, which are staggered. The clamping plates 103 on each rotating rod 102 are in the shape of a "U" and a mirror "U". The concave surface of the clamping plate 103 is provided with anti-slip texture 104. This device is mostly fixed to the rod near the handlebar of the frame, so it does not affect the user's grip on the handlebar to drive the vehicle. At the same time, it is also convenient for the user to view the instrument. Therefore, the "U" shaped and mirror "U" shaped clamping plates 103 can clamp the cylindrical rod more tightly. In addition, the anti-slip texture 104 increases the friction with the frame.

[0030] Wherein: mounting plates 105 are fixedly provided on the upper edges of both sides of the support base 100, and screw holes 106 are opened on the mounting plates 105. The outer shell of the instrument is provided with a fixing plate corresponding to the mounting plate 105, and mounting holes aligned with the mounting plate 105 are opened on the fixing plate. The instrument can be installed on the top of the support base 100 by means of suitable bolts, etc.

[0031] Wherein: the lead angle of the worm 203 is smaller than the equivalent friction angle between the meshing teeth of the worm wheel 204, the mechanism has self-locking property, and can achieve reverse self-locking, that is, only the worm 203 can drive the worm wheel 204, and the worm wheel 204 cannot drive the worm 203, so that the rotation rod 102 is more stable after the angle is adjusted;

[0032] Wherein: one end of the drive rod 206 extends and rotatably penetrates the side wall of the control box 200, and an anti-slip knob 208 is fixedly provided at the end. The outer side of the anti-slip knob 208 is provided with anti-slip texture, and the drive rod 206 can be easily rotated through the anti-slip knob 208.

[0033] In practical use, the clamping plates 103 on both sides are placed on the rod body of the frame that needs to be fixed. The anti-slip knob 208 drives the drive rod 206 to rotate. After the second speed-up gear 207 and the first speed-up gear 205 speed up the follower rod 202, the worm 203 and worm wheel 204 are driven to rotate. This causes the rotating rod 102 to drive one gear 201 to rotate, and the other gear 201 to rotate in the opposite direction. This causes the clamping plates 103 on both sides to gradually move closer to the rod body until the rod body is clamped. This allows for clamping and installing rod bodies of different sizes. Furthermore, because the worm 203 and worm wheel 204 have self-locking properties, only the worm 203 can drive the worm wheel 204, and the worm wheel 204 cannot drive the worm 203. This makes the clamping plates 103 on both sides more stable after clamping the rod body.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
