[0028] The utility model will be explained in further detail below according to the drawings and examples. The described examples are only a part of the examples of the utility model, not all examples. Based on the examples in the utility model, all other examples obtained by the ordinary skill in the art without making creative labor belong to the scope of protection of the utility model.

[0029] As Figure 1 , 3 and 5, a self-inclination suspension swing arm inclination locking mechanism for a three-wheeled electric vehicle, comprising a tooth plate 2 for being fixedly connected with an upper swing arm 101 or a lower swing arm 102 of a self-inclination suspension 1, the tooth plate 2 comprising an arc-shaped tooth surface 201;

[0030] Further comprising a tooth block 3 capable of engaging with the arc-shaped tooth surface 201, the tooth block 3 being movably arranged in a tooth block sliding groove 402 and being provided with a tooth block ascending drive module 5 capable of driving the tooth block 3 to ascend along the tooth block sliding groove 402 at a position adjacent to the tooth block sliding groove 402, and a tooth block descending drive module 6 capable of driving the tooth block 3 to descend along the tooth block sliding groove 402.

[0031] In the embodiment, the tooth plate 3 can swing left and right synchronously with the self-inclination suspension 1 relative to the vehicle frame, and the tooth block sliding groove 402 is fixed in position relative to the vehicle frame.

[0032] The tooth surface of the tooth block 3 is downwardly directed, facilitating the action on the arc-shaped tooth surface below. The length of the tooth block 3 is not less than the length of the tooth block sliding groove 402, so that the tooth surface of the tooth block 3 is engaged with the arc-shaped tooth surface 201 under the action of the pressure rod 601.

[0033] As Figure 3 and 4 As shown in the initial state, the tooth block 3 is driven by the tooth block ascending drive module 5 to be in a disengaged state with the tooth plate 3, and at this time, the self-inclination suspension 1 can swing freely. When it is required to maintain a certain inclination angle for driving, such as turning driving or circle driving, the tooth block 3 is driven to descend by the tooth block descending drive module 6 and is engaged with the arc-shaped tooth surface of the tooth plate 3, so as to achieve the purpose of locking the inclination of the self-inclination suspension 1.

[0034] As Figure 1As shown, in this embodiment, the tooth block slide groove 402 consists of a support plate 4 that can be fixedly connected to the vehicle frame, and slide rails 401 symmetrically arranged on the support plate 4 and located on the same side as the tooth plate 2. In this embodiment, the two slide rails 401 and the side of the support plate 4 form the tooth block slide groove 402, which allows the tooth block 3 to slide and move in a limited manner. The support plate 4 is fixed perpendicularly to the vehicle frame.

[0035] The tooth block slide groove 402 has a vertically arranged waist-shaped groove 403 that can penetrate the support plate 4 at the axial position;

[0036] The tooth block rising drive module 5 includes a tooth block pin 501 with one end connected to the tooth block 3 and the other end passing through the waist-shaped groove 403 to the inner side of the support plate 4, and a tension spring pin 502 disposed on the inner side of the support plate 4 and located above the waist-shaped groove 403; the tension spring pin 502 is connected to the tooth block pin 501 by the tension spring 503.

[0037] Under this structure, the toothed block can be kept in a state of disengagement from the arc-shaped tooth surface of the toothed plate 2 under the action of the tension spring contraction force, so as to unlock the free swing of the self-tilting suspension 1 and enable it to swing freely.

[0038] like Figure 1 As shown, the tooth block descent drive module 6 in this embodiment includes a pressure rod 601 disposed on the outer side of the support plate 4 and capable of acting on the top of the tooth block 3. One end of the pressure rod 601 is hinged to the support plate 4 through a pressure rod pin 602, and the other end is connected to a brake cable device 603. The handbrake can drive the brake cable device 603 to act on the pressure rod, thereby driving the pressure rod to act on the tooth block in the initial state and causing it to slide down along the tooth block slide groove 402 until it engages with the arc-shaped tooth surface 201, thereby achieving the purpose of locking the tilt angle of the self-tilting suspension 1.

[0039] In this state, the tension spring 503 is pulled up because the tooth block 3 has moved downward. After the pressure of the pressure rod 601 on the tooth block 3 is released, the tooth block 3 can rise on its own under the action of the tension spring 503, thus separating from the arc-shaped tooth surface 201.

[0040] It should be noted that the brake cable device 603 in the embodiment is a common device for vehicles on the market, which is mainly composed of a brake cable, a cable tube and a lever device. One end of the brake cable is fixed to the handle, and the other end is connected to the brake component through the cable tube. The inside of the cable tube is steel, and the outer layer is wrapped with rubber, which has a certain bending degree but a fixed length. The lever device usually includes a fixed arm connected to the bicycle handle and a movable arm connected to the brake cable. When the handle is pulled, the movable arm will move along the fixed arm, thereby tightening or loosening the brake cable, achieving the brake effect. The embodiment only uses it to control the pressure rod, and the principle of action is not repeated.

[0041] The pressure rod 601 in the embodiment includes a first pressure arm 604 and a second pressure arm 605 connected at an angle, so as to better act on the top of the tooth block 3.

[0042] The tooth plate 2 includes a tooth plate body 202 and fixed feet 203 symmetrically arranged at both ends of the tooth plate body 202, and the outer side of the tooth plate body 202 is provided with the arc-shaped tooth surface 201.

[0043] The tooth plate body 202, the fixed feet 203 and the arc-shaped tooth surface 201 are integrally formed.

[0044] The fixed feet 203 in the embodiment are also provided with connecting holes 204, so as to be connected and fixed with the upper rocker arm 101 or the lower rocker arm 102 of the self-inclination suspension 1 through screws.

[0045] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements within the technical range disclosed by the present application can be thought of by anyone skilled in the art, and are all covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
