[0002] With technological advancements in the bicycle transmission industry, electronic shifting has gradually become mainstream. The principle behind electronic bicycle shifting is that a sensor detects the displacement signal of the shift cable's mounting bracket, feeds this signal back to a controller, and then adjusts the direction and speed of the reduction motor to achieve precise control of the shift cable's displacement. Electronic bicycle shifting uses a sensor to detect the displacement signal of the shift cable's mounting bracket and feeds this signal back to the controller. Based on this feedback, the controller adjusts the direction and speed of the reduction motor to achieve precise control of the shift cable's displacement. However, current manual shifting still suffers from drawbacks such as short key travel, and the key feel also needs improvement. Utility Model Content

[0030] See below Figure 1 and Figure 2 The electronic speed controller provided by the embodiment of the present invention is applied to a bicycle hand shift, wherein the bicycle hand shift comprises an operating assembly 1, the operating assembly comprises an operating base 11, and the electronic speed controller comprises:

[0031] A speed change switch assembly 111 is provided on the operating base 11;

[0032] The shift button assembly 112 is arranged above the speed switch assembly 111;

[0033] The elastic member 113 has one end connected to the speed switch assembly 111 and the other end connected to the shift button 112 ; wherein the elastic member 113 is a barrel spring or a tower spring.

[0034] In this embodiment, the electronic speed controller includes a speed switch assembly 111, a shift button assembly 112, and an elastic member 113 disposed between the speed switch assembly 111 and the shift button assembly 112. In this embodiment, by disposing the elastic member 113 between the shift button assembly 112 and the speed switch assembly 111, and using a barrel spring or a conical spring as the elastic member 113, the button travel is increased, and when the user presses the button to shift gears, a good button feel is generated, thereby improving the user experience of the bicycle.

[0035] Compared to ordinary compression springs, barrel springs not only provide uniform damping force but also extend service life and key travel. Specifically, while barrel springs and ordinary straight-tube compression springs with identical materials, wire diameters, outer diameters, and heights offer similar compression forces, barrel springs offer greater travel. This is due to their different shapes. For example, when compressed, ordinary compression springs reach their lowest point, equivalent to the height of the stacked coils. In contrast, barrel springs can be staggered, achieving compression to the height of only one coil. Furthermore, for the same compression height, barrel springs offer a longer lifespan than ordinary compression springs. Conical springs are a type of shock-absorbing spring characterized by their compact size, high load capacity, and variable stiffness. They are widely used in applications with limited space and high loads, as well as in shock-absorbing devices. Furthermore, the outer diameters of barrel springs are smaller at their ends than in the middle, and the coils of a conical spring gradually increase or decrease in diameter from one end to the other. When the button is pressed, when the barrel spring or the tower spring is compressed to a certain extent, the speed change switch assembly 111 is triggered, thereby generating a gear change signal.

[0036] In one embodiment, the shift button assembly 112 includes a plurality of button positions 1121 , and each of the button positions 1121 is connected to an elastic member 113 .

[0037] Furthermore, a button column 1122 is provided on a side of each button position 1121 facing the speed change switch assembly 111 , and the button column 1122 is connected to the elastic member 113 .

[0038] In a specific embodiment, the shift button assembly 112 includes a button position 1121 and a button column 1122. The upper end of the button column 1122 is fixed to the button position 1121, and the lower end of the button column 1122 is connected to the elastic member 113. When the user presses the button position 1121, the elastic member 113 provides uniform damping force and, after being compressed to a certain degree, triggers the speed switch assembly 111, thereby generating a shift signal. There can be multiple button positions 1121, and correspondingly, multiple groups of elastic members 113, with each button position 1121 corresponding to an elastic member 113. Furthermore, the multiple groups of elastic members 113 can be staggered, allowing key control of different gears. For example, two groups of elastic members 113 can be provided, each connected to a different shift button in the shift button assembly 112, thereby enabling the shift button to change between two gears.

[0039] In one embodiment, a first mounting groove 1111 is provided on a side of the speed change switch assembly close to the elastic member 113, a second mounting groove 1123 is provided at the connection between the button position 1121 and the button column 1122, and both ends of the elastic member 113 are fixedly sleeved in the first mounting groove 1111 and the second mounting groove 1123 respectively.

[0040] In this embodiment, mounting grooves for fixing the elastic member 113 are provided on both the speed switch assembly 111 and the shift button assembly 112, so that the elastic member 113 can be fixedly installed, thereby ensuring the stability of the shifting process and avoiding unreliable shifting due to unstable connection of the elastic member 113 after repeated use.

[0041] In addition, in the unpressed state, the length of the elastic member 113 is greater than half of the distance between the speed switch assembly 111 and the shift button assembly 112 .

[0042] In a normal state (i.e., neither compressed nor stretched), the length of the elastic member 113 is greater than half the distance between the speed change switch assembly 111 and the shift button assembly 112. It is understood that when the elastic member 113 is neither compressed nor stretched, the distance between the speed change switch assembly 111 and the shift button assembly 112 does not change. Selecting an elastic member 113 longer than half the internal space (i.e., the distance between the speed change switch assembly 111 and the shift button assembly 112) and installing the elastic member 113 therein creates an appropriate preload, thereby further improving the feel of the buttons.

[0043] In practical applications, the initial space height of the shift button assembly 112 can be set to 6.6mm, the trigger height to 2.5mm, and the barrel spring specifications to 0.5mm wire diameter, 6.9mm outer diameter, and 12mm height. In other words, the elastic member 113 has a telescopic range of 2.5mm to 6.6mm.

[0044] An embodiment of the present invention further provides a bicycle hand shift, comprising the electronic speed change controller as described in any one of the above items.

[0045] In one embodiment, the bicycle handlebars further include a grip assembly 2 connected to one end of the operating assembly 1 , and the operating assembly 1 includes a flow guide mechanism 114 disposed in the operating base 11 and away from one end of the grip assembly 2 .

[0046] Furthermore, the diversion mechanism 114 includes at least one diversion groove disposed toward the ground.

[0047] In addition, the electronic speed controller abuts against the guide groove or extends into the guide groove.

[0048] In this embodiment, a diversion mechanism 114 is provided within the operating assembly 1, such as a diversion trough facing the ground. This diversion trough can drain rainwater and sediment from the cyclist's hand during rainy weather, thereby preventing rainwater from rusting the operating assembly 1 and preventing sediment from getting stuck, thereby further improving the user experience. In actual applications, multiple diversion troughs can be provided, and they can be located in corners where drainage is difficult.

[0049] In practical application scenarios, the slot holes of the guide trough can be of any shape, such as circular slot holes or square slot holes, etc. At the same time, the specifications of the slot holes can be set to be larger than a circle with a diameter of 3mm, so that small particles such as mud and sand can also be discharged from the guide trough.

[0050] An embodiment of the present invention further provides a bicycle, comprising the bicycle handlebar as described in any one of the above items.

[0051] The bicycle provided in this embodiment uses a barrel spring or a tower spring to connect the speed switch assembly 111 and the shift button assembly 112, so as to improve the user's usage feel. On the other hand, a diversion mechanism 114 is provided on the bicycle handlebars. When the user rides on a rainy day, rain and mud falling on the bicycle handlebars can flow out of the operating assembly 1 through the diversion mechanism 114. This can prevent rainwater from rusting the operating assembly 1 and prevent mud and sand from getting stuck in the operating assembly 1, thereby further improving the user experience.

[0052] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referred to each other. For the system disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part description. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of this application, several improvements and modifications can be made to this application, and these improvements and modifications also fall within the scope of protection of the claims of this application.

[0053] It should also be noted that, in this specification, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
