[0001] This utility model relates to the field of electric bicycle technology, specifically to a side-mounted motor support frame for electric bicycles. Background Technology

[0002] Side-mounted motors in electric bicycles typically refer to mid-mounted motors. These motors are usually installed inside the frame of the electric bicycle and positioned close to the rear wheel. However, most modern motors are fixed inside the frame with multiple screws, resulting in a large number of screws. This requires specialized installation and disassembly tools during disassembly and installation. The simple installation structure makes it impossible to move the motor outward to check the wiring or perform self-testing, affecting the overall practicality. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a side-mounted motor support frame for electric bicycles, in which the motor can be positioned by a single hand-tightened bolt locking ring, and the motor has an outward movement function, so as to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a side-mounted motor support frame for electric bicycles, applied to a motor, including a support ring. The support ring is sleeved on the outside of the motor. Multiple positioning blocks are installed in a ring structure on the outer wall of the motor. Each positioning block has a positioning groove with one open end on its outer side. A positioning strip is inserted into each positioning groove. Heat dissipation fins are installed on the outer side of each positioning strip. The other end of each heat dissipation fin is installed on the inner ring surface of the support ring. A locking mechanism is installed in the opening at one end of the support ring to press and fix the motor onto the support ring. Each positioning strip has a groove at the end away from the opening of the positioning groove. A compression spring is installed in each groove. A positioning ball is installed at the other end of each compression spring. The outer ring surface of each positioning ball is blocked by the positioning groove.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a side-mounted motor support frame for an electric bicycle, comprising a motor 1 and a support ring 2. The support ring 2 is sleeved on the outside of the motor 1. Multiple positioning blocks 7 are installed in a ring structure on the outer wall of the motor 1. Each positioning block 7 has a positioning groove with one open end on its outer side. A positioning strip 8 is inserted into each positioning groove. A heat dissipation fin 9 is installed on the outer side of each positioning strip 8. The other end of each heat dissipation fin 9 is installed on the inner ring surface of the support ring 2. A locking mechanism is installed in the opening at one end of the support ring 2 to press and fix the motor 1 onto the support ring 2. Each positioning strip 8 has a groove at the end away from the opening of the positioning groove. A compression spring is installed in each groove. A positioning ball 11 is installed at the other end of each compression spring. The outer ring surface of each positioning ball 11 is blocked by the positioning groove.

[0022] In this embodiment, the locking mechanism includes a connecting ring 5, a locking ring 3, and multiple connecting rods 4. The connecting ring 5 is disposed in the opening at one end of the support ring 2 and is threadedly connected to the support ring 2. The locking ring 3 is sleeved on the outside of the motor 1, and one end of the locking ring 3 is in contact with the positioning block 7. The multiple connecting rods 4 are installed between the connecting ring 5 and the locking ring 3.

[0023] In this embodiment, a first screw hole is provided on one side of the connecting ring 5, and a second screw hole is provided on the inner ring surface of the support ring 2 opposite to the first screw hole. A hand-tightening bolt 6 is threadedly connected to the first screw hole and the second screw hole.

[0024] In this embodiment, both the positioning strip 8 and the vertical cross-section of the positioning groove are trapezoidal, so that the positioning strip can only move along the positioning groove, thus preventing the positioning strip from directly detaching from the positioning groove.

[0025] In this embodiment, the positioning groove is provided with a ball groove that matches the positioning ball 11 on the end face facing the opening.

[0026] In this embodiment, a plurality of connecting ears 10 are installed in the opening at the other end of the support ring 2 in a ring structure. Each connecting ear 10 is provided with a plurality of fixing holes, and bolts can pass through the fixing holes to fix the connecting ears in the frame.

[0027] In this embodiment, the outer ring surface of the support ring 2 is provided with multiple heat dissipation vents in a ring structure, which increases the heat dissipation effect through the heat dissipation vents and heat dissipation fins.

[0028] During installation, the motor is inserted into the support ring, and the positioning block on the motor corresponds to the positioning strip and is fitted onto the positioning strip until the end face of the positioning strip abuts against the end face inside the positioning groove. After the above is completed, the connecting ring is threaded into the opening of the support ring. The rotation of the connecting ring drives the connecting rod and the locking ring until the locking ring abuts against the end face outside the positioning block, thereby locking the motor onto the support ring. In order to prevent the lock from loosening due to the rotation of the support ring itself, the hand-tightening bolt can be rotated so that the hand-tightening bolt threaded into the first screw hole and the second screw hole to ensure the stability after installation.

[0029] Furthermore, multi-point positioning can be achieved through positioning bars and positioning slots, and heat dissipation fins are installed on the outer surface of the positioning bars. The positioning blocks and positioning bars are made of metal materials, which allows the heat on the motor to be quickly transferred to the heat dissipation fins, thereby increasing the heat dissipation efficiency of the motor.

[0030] During subsequent maintenance, the hand-tightening bolt can be unscrewed (no tools are needed, and only one hand-tightening bolt needs to be manually rotated). After the hand-tightening bolt is removed, the connecting ring can be removed from the support ring, bringing out the locking ring. After the locking ring is removed, the motor can move outward along the positioning strip. The movement of the motor drives the positioning block. After the positioning block moves to a certain position, the ball groove will be aligned with the positioning ball. At this time, the rebound of the compression spring can push the positioning ball upward, so that the positioning ball is inserted into the ball groove to complete the positioning. At this time, the motor has basically moved to the outside, and it can be inspected without disengaging from the positioning strip. After the inspection is completed, it can be quickly pushed back without the need for alignment, which increases convenience.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
