Description

Technical Field

[0001] This utility model relates to electric scooters, and more particularly to electric scooters with a two-way acceleration and deceleration shifter structure. Background Technology

[0002] An electric scooter is a personal short-distance transportation device powered by electricity. It typically consists of a flat skateboard as the carrier, with wheels mounted on it, and is equipped with a motor and battery system to power the scooter.

[0003] Our patent application CN202411094449.9 discloses a two-way shifter mechanism for scooters, comprising a fixed part and a rotatable part relative to the fixed part. The shifter part has a bidirectional symmetrical reset track, while the fixed part has an elastic telescopic structure that cooperates with the reset track. The shifter part can rotate bidirectionally for adjustment and returns to its initial position after adjustment through the elastic telescopic structure and the reset track. The two-way shifter mechanism for scooters in this application features a spring reset structure. The Hall effect sensor is initially positioned in the center of the magnet. During use, the outer shell drives the magnet to rotate forward or backward. Moving it forward controls the motor speed, while moving it backward controls the intensity of the electronic brake. Furthermore, it is compact in size, uses bearings for smooth rotation, and has a central recess that fits the thumb, improving friction and user comfort. Finally, all components in this application are interconnected, resulting in a compact structure that is easy to install and disassemble.

[0004] However, during the installation process, it was found that this dial has two problems: 1. Because it uses an elastic telescopic structure, the initial position of the elastic telescopic structure must be in the middle of the reset track. Therefore, the pressing position is highly demanding during installation. However, the above-mentioned patent does not have a positioning structure during pressing, and it needs to be observed by the human eye; 2. The above-mentioned patent does not disclose the wiring structure. During installation, the signal wire may be damaged by friction from being moved. Utility Model Content

[0005] In view of the shortcomings of existing technologies, such as the inability to locate the device during installation and the possibility of wear and tear on the signal cable, this utility model provides an electric scooter with a bidirectional acceleration and deceleration shifter structure.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an electric scooter with a bidirectional acceleration and deceleration shifter structure, including an electric scooter body and a shifter set on the electric scooter body. The shifter includes a fixed seat, which is circular, and a shift ring rotatably sleeved on the fixed seat. The inner wall of the shift ring is provided with a reset groove that forms a V-shape when unfolded, and the fixed seat is provided with an elastic telescopic member that extends into the reset groove. Hall sensors and arc-shaped magnets are respectively provided in the fixed seat and the rotating sleeve to cooperate with each other to sense the rotation amplitude of the shift ring. A bearing is provided on the fixed seat. The inner wall of the shift ring is provided with a circular step, and it is rotatably connected to the fixed seat through the step and the bearing with an interference fit. One end of the shift ring is provided with a flange extending from its edge to the center. The fixed seat and the flange are provided with two sets of opposite positioning holes with the same diameter for inserting positioning pins for positioning during installation.

[0007] Preferably, in its natural state, the end of the elastic telescopic member abuts against the middle of the reset groove, and the Hall sensor is located in the middle of the magnet.

[0008] Preferably, the fixing seat includes a clamp that is locked by a locking screw and a mounting seat that is sleeved on the outside of the clamp and fixed to the clamp by a fastening screw. The mounting seat is an annular structure with a break and three arc-shaped petals on one side of the mounting seat, and the bearing is sleeved on the three petals.

[0009] Preferably, the end of the petal is provided with a limiting platform to limit the bearing and prevent the bearing from falling off the end of the petal, and the outer wall of the limiting platform is provided with a guide surface to facilitate the insertion of the petal into the bearing.

[0010] Preferably, the side wall of the mounting base is provided with two circumferentially extending annular plates, and two partitions are provided at the gap between the annular plates. The Hall sensor is located at the gap between the two annular plates, and its signal line passes through the two partitions and then exits from one of the annular plates.

[0011] Preferably, the two partitions are provided with through holes for signal lines to pass through, and the two through holes are staggered.

[0012] Preferably, the sidewall of the shift ring has several axial stripes to increase friction, and the sidewall of the shift ring has a through hole, which is opposite to the locking screw in its natural state.

[0013] Preferably, when the breaks of the mounting base are fully fitted, the outer wall of the petal-shaped body separates from the inner wall of the bearing.

[0014] Preferably, the elastic telescopic component includes a mounting cavity disposed on the mounting base, and a spring and a telescopic column are disposed in the mounting cavity. The spring applies elastic force to the telescopic column so that the telescopic column always abuts against the reset groove, so that the shift ring tends to rotate until the telescopic column is aligned with the center of the reset groove after rotation.

[0015] Compared with the prior art, the advantages of this utility model are as follows: The shifter in this application is provided with two sets of positioning holes. During the press-fitting process, the pin is inserted into the two sets of positioning holes for positioning before press-fitting, so as to ensure the relative position of the shift ring and the fixed seat, and ensure that the elastic telescopic part abuts against the middle of the reset groove in the initial state, and ultimately ensures the accuracy of the Hall sensor feedback signal.

Detailed Implementation

[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0028] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0029] This embodiment mainly describes the title of the electric scooter with a two-way acceleration and deceleration shifter structure, as follows:

[0030] Electric scooters with bidirectional acceleration and deceleration shifters, such as Figure 1-9 As shown, the device includes an electric scooter body 01 and a shifter 10 mounted on the electric scooter body 01. The shifter 10 includes a fixed base 101, both of which are annular, and a shift ring 102 rotatably mounted on the fixed base 101. The inner wall of the shift ring 102 is provided with a reset groove 1021 that unfolds into a V-shape, and the fixed base 101 is provided with an elastic telescopic member 40 that extends into the reset groove 1021. Hall sensors and arc-shaped magnets 20 are respectively provided in the fixed base 101 and the rotating sleeve to cooperate in sensing the rotation amplitude of the shift ring 102. The fixed base 101 is provided with a bearing 30. The inner wall of the shift ring 102 is provided with an annular step, and it is rotatably connected to the fixed base 101 through the step and the bearing 30 with an interference fit. One end of the shift ring 102 is provided with a flange 1022 extending from its edge to the center. The fixed base 101 and the flange 1022 are provided with two sets of opposing positioning holes 103 with the same diameter to insert positioning pins for positioning during installation. In this design, the shifter 10 is equipped with two sets of positioning holes 103. During press-fitting, the pins are inserted into the two sets of positioning holes 103 for positioning before press-fitting, so as to ensure the relative position of the shifter ring 102 and the fixed seat 101. Ultimately, this ensures that the elastic telescopic member 40 abuts against the middle of the reset groove 1021 in the initial state. When the elastic telescopic member 40 is in the middle of the reset groove 1021, the Hall sensor is directly opposite the middle position of the arc-shaped magnet 20.

[0031] Preferably, in its natural state, the end of the elastic telescopic member 40 abuts against the middle of the reset groove 1021, and the Hall sensor is located in the middle of the magnet 20. This solution is the optimal solution, which can ensure that the magnetic field strength sensed by the Hall sensor is the same when the finger ring 102 rotates to both sides by the same amount, so as to be used for acceleration or deceleration of the same magnitude.

[0032] Preferably, the fixing seat 101 includes a clamp 1010 that is locked by a locking screw and a mounting seat 1011 that is sleeved on the clamp 1010 and fixed to the clamp 1010 by a fastening screw. The mounting seat 1011 is an annular structure with a break and three arc-shaped petals 10111 are provided on one side of the mounting seat 1011. The bearing 30 is sleeved on the three petals 10111.

[0033] Preferably, the end of the petal 10111 is provided with a limiting platform 10112 to limit the bearing 30 and prevent the bearing 30 from falling off the end of the petal 10111. The outer side wall of the limiting platform 10112 is provided with a guide surface to facilitate the insertion of the petal 10111 into the bearing 30. The limiting platform 10112 is used to prevent the bearing 30 from falling off, while the guide surface is used to guide the petal 10111 when it is inserted into the bearing 30.

[0034] Preferably, the side wall of the mounting base 1011 is provided with two circumferentially extending annular plates 1012, and two partitions 1013 are provided at the gap between the annular plates 1012. The Hall sensor is disposed at the gap between the two annular plates 1012, and its signal line 100 passes through the two partitions 1013 and then exits from one of the annular plates 1012. The gap formed on the side of the annular plate 1012 is used for mounting the Hall sensor and routing the wiring.

[0035] Preferably, the two partitions 1013 are provided with through holes for the signal line 100 to pass through, and the two through holes are staggered. This solution provides two through holes for wiring, and the staggered arrangement ensures that when the signal line 100 bends, if it is subjected to external force, the force on the signal line 100 at the bend will not be transmitted to the connection between the signal line 100 and the Hall sensor, thus preventing it from falling off.

[0036] Preferably, the shift ring 102 has a plurality of axial stripes on its sidewall to increase friction, and the sidewall of the shift ring 102 has a through hole 1023, which is opposite to the locking screw in its natural state. This through hole 1023 is used to allow a screwdriver to be inserted to tighten or loosen the clamp 1010 in its natural state.

[0037] Preferably, when the breaks of the mounting base 1011 are fully fitted, the outer wall of the petal 10111 separates from the inner wall of the bearing 30. This design provides space for the installation and removal of the bearing 30.

[0038] Preferably, the elastic telescopic member 40 includes a mounting cavity disposed on the mounting base 1011. A spring 401 and a telescopic post 402 are disposed within the mounting cavity. The spring 401 applies a spring force to the telescopic post 402, ensuring that the telescopic post 402 always abuts against the reset groove 1021, causing the shift ring 102 to tend to rotate until the telescopic post 402 aligns with the center of the reset groove 1021 after rotation. When the shift ring 102 rotates, the telescopic post 402 abuts against the helical surface of the reset groove 1021, applying a reset force to the shift ring 102. When the telescopic post 402 abuts against the center of the reset groove 1021, the spring 401 is in its natural state.

[0039] The electric scooter body 01 has a controller on its pedal section, and a signal line 100 is connected to the controller to provide signal feedback for accelerating or decelerating the hub motor.

[0040] The title provided above provides a detailed description of the present utility model. Specific examples have been used to illustrate the principles and implementation methods of the present utility model. The description of the above embodiments is only for the purpose of helping to understand the present utility model and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to the present utility model without departing from the principles of the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
