Abstract
Description
Technical Field
[0001] The embodiments of this disclosure generally relate to the field of electric bicycle technology, and more specifically, to a front assembly and an electric bicycle. Background Technology
[0002] The central control unit is one of the core components of an electric bicycle. To meet the high-precision positioning and 90° parking functions of the central control unit, its installation location needs to avoid obstruction by objects and components to prevent interference with the signal.
[0003] To address these issues, one approach is to mount the center console on the head tube at the front of the vehicle to meet functional requirements. However, this protrudes forward, requiring a large area of plastic enclosure, making it unsuitable for basic models. Another approach is to mount the center console on the handlebar assembly, causing it to rotate with the handlebars and preventing the 90° parking function from being used. To enable the 90° parking function, the center console could be pulled outwards and mounted separately on the frame; however, this would increase cost and the likelihood of failure. Utility Model Content
[0004] The purpose of this disclosure is to provide a front-end assembly and an electric bicycle to at least partially solve the aforementioned problems.
[0005] In a first aspect of this disclosure, a front end assembly is provided, the front end assembly including a frame; a fork rotatably connected to the frame; a handlebar assembly connected to the fork; a bearing disposed on the handlebar assembly; a center control disposed around and connected to the bearing; and a connector, one end of the connector being connected to the center control and the other end of the connector being connected to the frame.
[0006] According to embodiments of this disclosure, since the center control is connected to the handlebar assembly via a bearing, and the connector and frame can fix the center control to limit its rotation, the center control does not rotate with the handlebar assembly when the handlebar assembly rotates, allowing the electric bicycle to use the 90° parking function. Furthermore, this installation method reduces vehicle costs and the failure rate of the center control installation. Additionally, this installation method eliminates the need for a large area of plastic covering the center control, saving space and reducing costs.

[0008] In some embodiments, the main body further includes a blocking portion disposed adjacent to the mounting portion and closer to the fork than to the mounting portion, and the bearing abuts against the blocking portion.
[0009] In some embodiments, the mounting portion includes a mounting shaft, the blocking portion includes a blocking step, and the radial dimension of the blocking step is larger than the radial dimension of the mounting shaft.
[0010] In some embodiments, the handlebar assembly further includes a pair of handlebars disposed on the main body, each of the pair of handlebars including a bend, the bend of each of the pair of handlebars being bent toward a direction away from the center control to be spaced apart from the center control.
[0011] In some embodiments, the control includes a first bracket and a body portion disposed on the first bracket, the first bracket including a mounting groove opposite to the body portion, and the bearing disposed within the mounting groove.
[0012] In some embodiments, the connector extends along the axial direction of the bearing and is spaced apart from the handlebar assembly and the fork.
[0013] In some embodiments, one end of the connector is connected to the side of the first bracket away from the bend, the frame includes a second bracket, and the other end of the connector is connected to the second bracket.

[0030] Preferred embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.
[0031] The term "comprising" and its variations as used herein signify open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc., may refer to different or the same objects.
[0032] In the following description, the principles of this disclosure will be illustrated using an electric bicycle as an example of the application environment of the front assembly 100. However, it should be understood that this application environment is merely exemplary, and the front assembly 100 according to embodiments of this disclosure can also be applied to various other vehicles.
[0033] Figure 1 A schematic diagram of the structure of a front-end assembly 100 according to some embodiments of the present disclosure is shown. Figure 2 It shows Figure 1 An exploded view of the front-end assembly 100 is shown. Figures 1 to 2 As shown, the head unit 100 described herein generally includes a front fork 1, a frame 2, a handlebar assembly 3, a center control 4, a bearing 5, a connector 6, and fasteners 7. The front fork 1 is connected to the handlebar assembly 3. The front fork 1 extends through the frame 2 and is rotatably connected to the frame 2. Thus, when the handlebar assembly 3 is rotated, the front fork 1 can rotate with the handlebar assembly 3.
[0034] refer to Figures 1 to 2 In some embodiments, the bearing 5 is mounted on the handlebar assembly 3. A center control 4 is positioned around the bearing 5 and connected to it. One end of a connector 6 is connected to the center control 4, and the other end is connected to the frame 2.
[0035] According to embodiments of this disclosure, since the center control 4 is connected to the handlebar assembly 3 via the bearing 5, and the connector 6 and the frame 2 can fix the center control 4 to restrict its rotation, the center control 4 does not rotate with the handlebar assembly 3 when the handlebar assembly 3 rotates. This allows the electric bicycle to use the 90° parking function without needing to pull the center control outward and install it separately on the frame 2, thus reducing vehicle cost and the failure rate of the center control 4 installation. Furthermore, since the center control 4 is installed on the handlebar assembly 3, there is no need to use a large area of plastic to enclose it, saving space and reducing costs, making it suitable for simpler models, and preventing items or parts from obstructing the center control 4.
[0036] Figure 3 It shows Figure 1 The diagram shows the structure of handlebar assembly 3. Figures 1 to 3 As shown, in some embodiments, the center control 4 needs to be spaced apart from the handlebar assembly 3 to avoid the center control 4 interfering with the rotation of the handlebar assembly 3. The handlebar assembly 3 may include a body 31. One end of the body 31 may be connected to the fork 1. The body 31 may include a mounting portion 311 disposed at the other end. The bearing 5 may be disposed around the mounting portion 311.
[0037] refer to Figures 1 to 3 In some embodiments, the main body 31 may further include a blocking portion 312. The blocking portion 312 may be disposed adjacent to the mounting portion 311, and the blocking portion 312 is closer to the fork 1 than the mounting portion 311. The bearing 5 can abut against the blocking portion 312. With the above configuration, when the bearing 5 is disposed around the mounting portion 311, the blocking portion 312 can block the bearing 5 and prevent the bearing 5 from moving toward the fork 1.
[0038] Furthermore, the mounting portion 311 may include a mounting shaft to improve compatibility with the bearing 5. In some embodiments, to restrain the bearing 5 in place, the blocking portion 312 may include a blocking step, such as... Figure 3 As shown. The radial dimension of the blocking step can be larger than the radial dimension of the mounting shaft to block the bearing 5. It should be understood that in other embodiments, the blocking part 312 can adopt any other suitable structure to block the bearing 5 to confine the bearing 5 in place.
[0039] Continue to refer to Figures 1 to 3 In some embodiments, the handlebar assembly 3 may further include a pair of handlebars 32 disposed on the main body 31. Since the center control 4 is adjacent to the pair of handlebars 32, the center control 4 needs to be spaced apart from the pair of handlebars 32 to avoid the center control 4 interfering with the rotation of the handlebar assembly 3. To avoid the center control 4 interfering with the rotation of the handlebar assembly 3, such as... Figure 3 As shown, each of the pair of handlebars 32 may include a bent portion 321. The bent portions 321 of the pair of handlebars 32 are each bent in a direction away from the center control 4, thus spaced apart from the center control 4. This prevents the handlebar assembly 3 from interfering with the center control 4 during rotation. It should be understood that in other embodiments, the pair of handlebars 32 may employ any other suitable structure to space them apart from the center control 4 to prevent the center control 4 from interfering with the rotation of the handlebar assembly 3.
[0040] Figure 4 A schematic diagram of the structure of a first support 41 according to some embodiments of the present disclosure is shown. For example... Figure 1 , Figure 2 as well as Figure 4 As shown, in some embodiments, the control 4 may include a first bracket 41 and a body portion 42 disposed on the first bracket 41. For mounting the bearing 5, as... Figure 4 As shown, the first bracket 41 may include a mounting groove 411 opposite to the body portion 42. The bearing 5 may be disposed within the mounting groove 411. It should be understood that in other embodiments, the first bracket 41 may employ any other suitable structure to mount the bearing 5.
[0041] With the above configuration, after the bearing 5 is assembled with the mounting groove 411, the inner surface of the mounting groove 411 can contact the bearing 5, so that the bearing 5 supports the first bracket 41. Furthermore, since the bearing 5 is connected to the first bracket 41 and is arranged around the mounting portion 311, the fixing effect of the connector 6 and the frame 2 prevents the bearing 5 and the center control 4 from detaching from the upper end of the front assembly 100. In addition, the shape of the first bracket 41 can be adjusted according to the shape of the body portion 42, the mounting angle of the body portion 42, and other installation requirements to meet the installation requirements of the center control 4, such as horizontal installation.
[0042] Return Reference Figures 1 to 3 In some embodiments, to prevent the connector 6 from interfering with the rotation of the handlebar assembly 3 and the fork 1, the connector 6 may extend along the axial direction X of the bearing 5 and be spaced apart from the handlebar assembly 3 and the fork 1. This prevents the handlebar assembly 3 and the fork 1 from interfering with the connector 6 during rotation. It should be understood that in other embodiments, the connector 6 may employ any other suitable structure to be spaced apart from the handlebar assembly 3 and the fork 1 to prevent the connector 6 from interfering with the rotation of the handlebar assembly 3 and the fork 1.
[0043] refer to Figures 1 to 3 In some embodiments, one end of the connector 6 may be connected to the side of the first bracket 41 opposite to the bend 321. The frame 2 may include a second bracket 21. The other end of the connector 6 may be connected to the second bracket 21. Thus, the connector 6 can be spaced apart from the handlebar assembly 3 and the fork 1 to avoid the connector 6 interfering with the rotation of the handlebar assembly 3 and the fork 1.
[0044] Return Reference Figure 2 In some embodiments, the connector 6 can be connected to the first bracket 41 and the second bracket 21 via fasteners 7. The fastener 7 according to embodiments of this disclosure can be of various types known or available in the future, and embodiments of this disclosure do not limit this. For example, in some embodiments, the fastener 7 can be a screw or bolt, etc.
[0045] Furthermore, return to the reference. Figure 2 and Figure 4 The first bracket 41 has a pair of first threaded holes 412 on the side opposite to the bent portion 321. Correspondingly, the second bracket 21 has a pair of second threaded holes 211. Therefore, each fastener 7 passes through the connector 6 and is locked in the corresponding first threaded hole 412 or the corresponding second threaded hole 211, ensuring the assembly stability of the connector 6 with the first bracket 41 and the second bracket 21.
[0046] It should be noted that the numbers, values, and quantities mentioned above, as well as elsewhere in this disclosure, are exemplary and are not intended to limit the scope of this disclosure in any way. Any other suitable numbers, values, and quantities are possible. For example, depending on the specific application scenario and requirements, the first threaded hole 412 and the second threaded hole 211 may include more or fewer quantities.
