Description

Technical Field

[0001] This utility model relates to the field of handlebar assembly technology, specifically to a handlebar assembly with a finger lever. Background Technology

[0002] In existing electric bicycle handlebar assemblies, the fastening sleeve, as a core component connecting the handlebars and the base, directly affects the handling stability and riding experience of the electric bicycle due to the reliability of its limiting structure. In traditional technology, the fastening sleeve is generally limited by using fasteners to compress it against the handlebars. That is, in its natural state, the radius of the cavity of the fastening sleeve is larger than the outer diameter of the handlebars. Fasteners such as bolts are used to compress the outer circumference of the fastening sleeve, causing it to undergo radial contraction deformation to hold the handlebars tightly, thereby preventing relative rotation between the two.

[0003] However, this solution has the following drawbacks: when the fastening sleeve is pressed tightly against the handlebars by the fastener, the sleeve deforms, causing it to fail to fit tightly against the base, resulting in a gap between the sleeve and the base. During electric vehicle operation, factors such as road bumps can cause relative movement and rotation between the sleeve and the base within this gap, leading to abnormal noise. Therefore, there is an urgent need for a fastening sleeve structure that can effectively achieve circumferential limiting. Summary of the Invention

[0004] The purpose of this invention is to address the problem in existing technologies where there is a gap between the fastening sleeve and the base, causing relative movement and rotation between the fastening sleeve and the base within this gap, resulting in abnormal noise. This invention provides a handlebar assembly with a finger shifter.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a handlebar assembly with a finger lever, comprising a housing having a first receiving cavity, a base snapped into the first receiving cavity, a side cover disposed at the end of the housing away from the base, and a sensing device installed on the housing and the base, wherein the sensing device is used to acquire the rotation angle information of the housing;

[0006] When the housing rotates relative to the base, the sensing device can quickly obtain the size and direction of the housing's rotation angle as information on acceleration or deceleration, as well as the magnitude of acceleration or deceleration, and provide the above information to the transmission device so that the electric vehicle can make corresponding acceleration or deceleration responses.

[0007] The housing is rotatable relative to the base. The base has a second receiving cavity, in which a fastening sleeve is provided. The fastening sleeve has a first boss protruding radially outward. The base has a limiting groove that fits against the first boss. The tight fit between the first boss and the limiting groove forms a rigid anti-rotation structure, which effectively solves the problem of circumferential loosening of the fastening sleeve, thereby ensuring the stability of the horizontal assembly structure.

[0008] The fastening sleeve has a third receiving cavity, the side cover has a fourth receiving cavity, and the handlebar is inserted into the first receiving cavity, the second receiving cavity, the third receiving cavity and the fourth receiving cavity. A grip is provided at the end of the side cover away from the housing, and the grip is sleeved on the outer periphery of the handlebar.

[0009] The fastening sleeve is fixedly installed on the handlebars by fasteners.

[0010] The fastening sleeve also has a second boss and a third boss arranged in opposite positions. The second receiving cavity has a limiting area for installing the second boss and the third boss. The second boss and the third boss are connected by fasteners. The base and the housing are respectively provided with coaxial countersunk holes and through holes. The countersunk holes and through holes are used for fasteners to pass through and assemble.

[0011] In the above technical solution, the fastener squeezes the outer periphery of the fastening sleeve, causing the fastening sleeve to undergo radial contraction deformation to grip the handlebar, thereby preventing relative rotation between the two. The countersunk hole and through hole are used to facilitate the avoidance of the fastener, thereby preventing the base from blocking the fastener and making it impossible to install.

[0012] Preferably, the sensing device includes a set of magnets and a Hall sensor, wherein the set of magnets is mounted on the housing and the Hall sensor is mounted on the base.

[0013] In the above technical solution, when the housing rotates relative to the base, the magnet generates an angular displacement relative to the Hall sensor. The Hall sensor receives the angular displacement signal of the magnet and transmits the signal to the transmission device of the electric vehicle, thereby realizing the acceleration and deceleration of the electric vehicle.

[0014] Preferably, the output end of the Hall sensor is equipped with a signal harness, and a first wire hole is provided in the base for the signal harness to pass through. The outlet end of the first wire hole is located on the edge of the end face of the base. A second wire hole is provided in the handlebar along the axial direction. The signal harness passes through the outlet end and then enters the second wire hole.

[0015] In the above technical solution, the signal harness is connected by external wiring, eliminating the need to install a mounting platform on the base to install the signal harness, resulting in a more compact structure; the inlet end of the second wire hole is located on the outer periphery of the handlebar, and the signal harness enters the handlebar through the inlet end.

[0016] Preferably, a cover plate is detachably connected to the edge of the base away from the handlebars, a connecting post is fixed to the side of the cover plate facing the handlebars, a connecting groove for inserting the connecting post is provided in the base, an internal threaded hole is provided at the end of the connecting post facing the handlebars, and the connecting post is threaded onto the base by a screw.

[0017] In the above technical solution, since the screws are installed on the end face of the base away from the cover plate, the screws are located inside the horizontal assembly after the horizontal assembly is installed, and there are no screws on the surface of the cover plate, making its appearance more aesthetically pleasing.

[0018] Preferably, the fastener is a bolt, and the second boss and the third boss have coaxial first threaded holes. The bolt passes through the countersunk hole and is threaded into the first threaded hole.

[0019] In the above technical solution, the bolt thread connection in the first threaded hole can generate radial contraction force in the fastening sleeve, thereby preventing the fastening sleeve and the handlebar from rotating relative to each other.

[0020] Preferably, the base has a second threaded hole coaxial with the first threaded hole, and the bolt is threaded into the second threaded hole.

[0021] In the above technical solution, the bolt threaded connection in the second threaded hole can fix the base and the fastener together. Since the fastener cannot move or rotate relative to the base, the fastening sleeve is fixed to the base and cannot rotate or move relative to it, thus achieving secondary circumferential limiting of the fastening sleeve and the base.

[0022] Preferably, a turn signal is installed at the end of the grip away from the housing.

[0023] In the above technical solution, the turn signal alerts other people when the electric vehicle turns, thereby reducing the risk of traffic accidents.

[0024] Preferably, it also includes a torsion spring, one end of which is connected to the housing and the other end of which is connected to the base.

[0025] In the above technical solution, after the shell rotates relative to the base, the torsion spring can provide a return force to the shell. At the same time, since the elastic force generated by the torsion spring is positively correlated with the deformation of the torsion spring, the greater the deformation of the torsion spring, the greater the return force felt by the user, thus making it convenient for the user to judge the speed by the return force.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] 1. The handlebar assembly with finger shifter has a fastening sleeve with a first boss protruding radially outward, and a limiting groove that fits with the first boss is provided on the base; the tight fit between the first boss and the limiting groove forms a rigid anti-rotation structure, which prevents the fastening sleeve from moving or rotating in the gap, effectively solves the problem of circumferential loosening of the fastening sleeve, and thus ensures the structural stability of the handlebar assembly.

[0028] 2. This lever assembly with a dial has a more compact structure because the output end of the first wire hole is located on the edge of the base end face, allowing the signal harness to be connected by external wiring. This eliminates the need for a mounting platform on the base to install the signal harness.

[0029] 3. The handlebar assembly with finger shifter has a second threaded hole on the base that is coaxial with the first threaded hole. The bolt is threaded into the second threaded hole. Threading the bolt into the second threaded hole can fix the base and the fastener together. Since the fastener cannot move or rotate relative to the base, the fastening sleeve is fixed to the base and cannot rotate or move relative to it, thus achieving secondary circumferential positioning of the fastening sleeve and the base.

[0035] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] Please refer to Figures 1 to 4In this embodiment, a handlebar assembly with a finger lever includes a housing 1 having a first receiving cavity, a base 2 snapped into the first receiving cavity, a side cover 3 disposed at the end of the housing 1 away from the base 2, and a sensing device 4 installed on the housing 1 and the base 2. The sensing device 4 is used to obtain the rotation angle information of the housing 1.

[0037] When the housing 1 rotates relative to the base 2, the sensing device 4 can quickly obtain the size and direction of the rotation angle of the housing 1 as information on acceleration or deceleration, and the magnitude of acceleration or deceleration, and provide the above information to the transmission device so that the electric vehicle can make a corresponding acceleration or deceleration response.

[0038] The housing 1 can rotate relative to the base 2. The base 2 has a second receiving cavity. A fastening sleeve 5 is provided in the second receiving cavity. The fastening sleeve 5 has a first boss 51 that protrudes outward in a radial direction. A limiting groove 52 that fits with the first boss 51 is provided on the base 2.

[0039] The tight fit between the first boss 51 and the limiting groove 52 forms a rigid anti-rotation structure, which effectively solves the problem of circumferential loosening of the fastening sleeve 5, thereby ensuring the stability of the horizontal assembly structure.

[0040] The fastening sleeve 5 has a third receiving cavity, the side cover 3 has a fourth receiving cavity, the handlebar 7 is inserted into the first receiving cavity, the second receiving cavity, the third receiving cavity and the fourth receiving cavity, and the side cover 3 has a handlebar 8 at the end away from the housing 1, and the handlebar 8 is sleeved on the outer periphery of the handlebar 7.

[0041] The fastening sleeve 5 is fixedly installed on the handlebar 7 by the fastener 6. The fastening sleeve 5 also has a second boss 53 and a third boss 54 arranged in opposite positions. The second receiving cavity has a limiting area 55 for installing the second boss 53 and the third boss 54. The second boss 53 and the third boss 54 are connected by the fastener 6. The base 2 and the housing 1 are respectively provided with a countersunk hole and a through hole, which are used for fasteners to pass through and assemble.

[0042] In the above technical solution, the fastener 6 squeezes the outer periphery of the fastening sleeve 5, causing the fastening sleeve 5 to undergo radial contraction deformation to grip the handlebar 7, thereby preventing the two from rotating relative to each other. The countersunk hole and through hole are used to facilitate the avoidance of the fastener 6, thereby preventing the base 2 from blocking the fastener 6 and making it impossible to install.

[0043] The sensing device 4 includes a set of magnets 41 and a Hall sensor 42. The set of magnets 41 is mounted on the housing 1, and the Hall sensor 42 is mounted on the base 2.

[0044] In the above technical solution, when the housing 1 rotates relative to the base 2, the magnet 41 generates an angular displacement relative to the Hall sensor 42. The Hall sensor 42 receives the angular displacement signal of the magnet 41 and transmits the signal to the transmission device of the electric vehicle, thereby realizing the acceleration and deceleration of the electric vehicle.

[0045] Please refer to Figures 1 to 3 The output end of the Hall sensor 42 is equipped with a signal harness 43. The base 2 has a first wire hole for the signal harness 43 to pass through. The wire outlet 44 of the first wire hole is located on the edge of the end face of the base 2. The handlebar 7 has a second wire hole 45 in the axial direction. The signal harness 43 passes through the wire outlet 44 and then enters the second wire hole 45.

[0046] In the above technical solution, the signal harness 43 is connected by external wiring, eliminating the need to set up a mounting platform on the base 2 to install the signal harness 43, making its structure more compact; the inlet end 46 of the second wire hole 45 is located on the outer periphery of the handlebar 7, and the signal harness 43 enters the handlebar 7 through the inlet end 46.

[0047] A cover plate 9 is detachably connected to the edge of the end face of the base 2 away from the handlebar 7. A connecting post 91 is fixed to the side of the cover plate 9 facing the handlebar 7. A connecting groove for inserting the connecting post 91 is opened in the base 2. An internal threaded hole is opened at the end of the connecting post 91 facing the handlebar 7. The connecting post 91 is connected to the base 2 by screw threads.

[0048] In the above technical solution, since the screw is installed on the end face of the base 2 away from the cover plate 9, the screw is located inside the horizontal assembly after the horizontal assembly is installed, and there will be no screw on the surface of the cover plate 9, making its appearance more aesthetically pleasing.

[0049] Fastener 6 is a bolt. The second boss 53 and the third boss 54 have coaxial first threaded holes. After the bolt passes through the countersunk hole, it is threaded into the first threaded hole.

[0050] In the above technical solution, the bolt thread connection in the first threaded hole can generate radial contraction force in the fastening sleeve 5, so that the fastening sleeve 5 and the handlebar 7 will not rotate relative to each other.

[0051] The base 2 has a second threaded hole coaxial with the first threaded hole, and the bolt is threaded into the second threaded hole.

[0052] In the above technical solution, the bolt threaded connection in the second threaded hole can fix the base 2 and the fastener 6 together. Since the fastener 6 cannot move or rotate relative to the base 2, the fastening sleeve 5 is fixed together with the base 2 and cannot rotate or move relative to it, thus achieving secondary circumferential limiting of the fastening sleeve 5 and the base 2.

[0053] Please refer to Figure 1 A turn signal 10 is installed at the end of the grip 8 away from the housing 1; a mounting groove is provided at the end of the grip 8 away from the housing 1, and the turn signal 10 is embedded in the mounting groove; two screws are threadedly connected to the outer periphery of the grip 8 to fix the turn signal 10 in the mounting groove.

[0054] In the above technical solution, the turn signal 10 alerts other people when the electric vehicle turns, thereby reducing the risk of traffic accidents.

[0055] Please refer to Figure 1 , Figure 2 and Figure 4 The horizontal assembly also includes a torsion spring 11, one end of which is connected to the housing 1 and the other end of which is connected to the base 2.

[0056] In the above technical solution, after the housing 1 rotates relative to the base 2, the torsion spring 11 can provide a return force to the housing 1. At the same time, since the elastic force generated by the torsion spring 11 is positively correlated with the deformation of the torsion spring 11, the greater the deformation of the torsion spring 11, the greater the return force felt by the user, thus making it convenient for the user to judge the speed by the return force.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
