Description

Technical Field

[0001] The utility model relates to the technical field of lower connecting plates for electric tricycles, in particular to a lower connecting plate for low-speed electric tricycles. Background Art

[0002] The lower connecting plate of an electric tricycle is a critical component, and its design directly impacts the vehicle's stability and service life. Traditional lower connecting plate designs have several drawbacks. For example, when connected to the vehicle's shock absorber, the rigid connection makes it susceptible to collision and damage during impact. When connected to the steering shaft, the connection area is also susceptible to corrosion from dust and debris, shortening its service life. To address these issues, the present invention provides a lower connecting plate for a low-speed electric tricycle. Utility Model Content

[0003] In view of the above-mentioned technical deficiencies, the purpose of the present utility model is to provide a lower connecting plate of a low-speed electric tricycle, in which a locking portion is provided inside the shock-absorbing sleeve to avoid rigid collision between the shock absorber and the shock-absorbing sleeve, and a sealing ring is provided to seal between the steering sleeve and the steering shaft.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a lower connecting plate of a low-speed electric tricycle, which is characterized by comprising:

[0005] A plate body, wherein the plate body is in a "︿" shape;

[0006] A steering sleeve, which is fixedly connected to the corner of the plate body and is used to connect with the steering shaft of the electric vehicle;

[0007] Two shock-absorbing sleeves, the two shock-absorbing sleeves are respectively fixedly connected to the two ends of the plate body and are used to be connected to the shock absorber of the electric vehicle;

[0008] Two locking parts are fixedly mounted on the inner ring surface of the shock absorbing sleeve.

[0009] Preferably, the locking portion comprises:

[0010] a ring body, the ring body being fixedly mounted on the inner annular surface of the shock-absorbing sleeve;

[0011] A plurality of convex rings are fixedly connected to the inner ring surface of the ring body, and the plurality of convex rings are evenly distributed along the axial direction of the ring body.

[0012] Preferably, the ring body and the convex ring are integrally formed, and the ring body and the convex ring are hollow structures.

[0013] Preferably, one end of the convex ring close to the axis of the ring body is tilted downward.

[0014] Preferably, a sealing ring is fixedly connected to the upper end surface of the direction sleeve, and the axes of the sealing ring and the direction sleeve are located on the same straight line, and the inner diameter of the sealing ring is smaller than the inner diameter of the direction sleeve.

[0015] Preferably, the shock-absorbing sleeve is provided with a notch, and protrusions are fixedly connected to both sides of the notch, and the two protrusions located on the same shock-absorbing sleeve are both provided with corresponding threaded holes.

[0016] Preferably, a plurality of reinforcing ribs are provided between the steering sleeve, the shock-absorbing sleeve and the plate body.

[0017] Preferably, a plurality of positioning blocks are fixedly connected to the upper side of the plate body.

[0018] The beneficial effects of the present invention are:

[0019] The utility model realizes, through the arrangement of the ring body and the convex ring, that when the shock-absorbing sleeve and the shock absorber of the electric vehicle are connected to each other, the inner ring surface of the convex ring can press against the shaft body on the shock absorber. Because the ring body and the convex ring are both hollow structures, when an impact occurs, the convex ring and the ring body will produce a certain elastic deformation, thereby avoiding a rigid collision between the shaft body of the shock absorber and the shock-absorbing sleeve, which may cause damage.

[0020] The utility model sets the end of the convex ring close to the ring body axis to be inclined downward, so that when the shock-absorbing sleeve and the shaft body of the shock absorber are connected to each other, the contact area between the convex ring and the shaft body of the shock absorber can be increased. Moreover, when in use, the shock-absorbing sleeve will be subjected to a downward force, and the direction of the force is opposite to the inclination direction of the convex ring, which can make the connection between the shock-absorbing sleeve and the shaft body of the shock absorber more stable.

[0021] The utility model realizes sealing between the steering sleeve and the steering shaft of the electric vehicle by providing the sealing ring, thereby preventing dust or debris from entering between the steering sleeve and the steering shaft, causing wear and reducing the service life of the electric vehicle.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The utility model provides a low-speed electric tricycle lower connecting plate, such as Figures 1 to 4 shown.

[0031] Example 1:

[0032] A lower connecting plate of a low-speed electric tricycle includes a plate body 1. The plate body 1 is in a "︿" shape. Steering sleeves 2 are fixedly connected to the corners of the plate body 1. The steering sleeve 2 is interconnected with the steering shaft on the electric vehicle. Shock-absorbing sleeves 3 are fixedly connected to both ends of the plate body 1. The shock-absorbing sleeves 3 are interconnected with the shock absorbers on the electric vehicle. A plurality of reinforcing ribs 7 are provided between the steering sleeve 2, the shock-absorbing sleeve 3 and the plate body 1, which can make the connection between the steering sleeve 2, the shock-absorbing sleeve 3 and the plate body 1 more stable.

[0033] A notch is provided on the shock-absorbing sleeve 3, and protrusions 6 are fixedly connected on both sides of the notch. Corresponding threaded holes are provided on the two protrusions 6 on the same shock-absorbing sleeve 3. The bolts are installed in the threaded holes on the protrusions 6, and the bolts are rotated clockwise to fix the hoop of the shock-absorbing sleeve 3 on the shaft of the shock absorber. The shock-absorbing sleeve 3 is connected to the shaft of the shock absorber, and the disassembly and assembly of the shock-absorbing sleeve 3 can be controlled by rotating the bolts.

[0034] A plurality of positioning blocks 8 are fixedly connected to the upper side of the plate body 1. During installation, the positioning blocks 8 can play a positioning role, making it convenient for the staff to connect the utility model with the corresponding parts on the electric vehicle for installation.

[0035] Example 2:

[0036] On the basis of Example 1, in order to avoid the lack of buffering between the shock-absorbing sleeve 3 and the shaft of the shock absorber when an impact occurs, resulting in a rigid collision and damage, a locking portion 4 is provided on the inner ring surface of the shock-absorbing sleeve 3, and a notch corresponding to the shock-absorbing sleeve 3 is also provided on the locking portion 4. The locking portion 4 can produce elastic deformation (for example, the material of the locking portion 4 can be a stainless steel sheet).

[0037] Furthermore, the locking portion 4 may be configured as follows:

[0038] The locking portion includes a ring body 401, which is fixedly mounted on the inner ring surface of the shock-absorbing sleeve 3. A plurality of convex rings 402 are fixedly connected to the inner ring surface of the ring body 401. The plurality of convex rings 402 are evenly distributed on the inner ring surface of the ring body 401 along the axial direction of the ring body 401. The convex rings 402 are integrally formed with the ring body 401, and one end of the convex ring 402 close to the axis of the ring body 401 is tilted downward.

[0039] When the shock-absorbing sleeve 3 is installed on the shaft of the shock absorber, the convex ring 402 will apply a pressing force to the shaft of the shock absorber. At the same time, because the end of the convex ring 402 close to the axis of the ring body 401 is tilted downward, the contact area between the convex ring 402 and the shock absorber shaft can be increased. In addition, when in use, the shock-absorbing sleeve 3 will be subjected to a downward force, and the direction of this force is opposite to the direction of inclination of the convex ring 402, thereby making the connection between the shock-absorbing sleeve 3 and the shaft of the shock absorber more stable.

[0040] The ring body 401 and the convex ring 402 are both hollow structures. When an impact occurs, the convex ring 402 and the ring body 401 will produce a certain elastic deformation under the force, thereby offsetting the impact force and avoiding rigid collision between the shock absorber shaft and the shock absorbing sleeve 3, which may cause damage.

[0041] Example 3:

[0042] A sealing ring 5 is fixedly connected to the upper end surface of the steering sleeve 2. The material of the sealing ring 5 is soft rubber. The axis of the sealing ring 5 is in the same straight line as the axis of the steering sleeve 2, and the inner diameter of the sealing ring 5 is smaller than the inner diameter of the steering sleeve 2. After installation, the inner ring surface of the sealing ring 5 will be stretched by the steering shaft of the electric vehicle, so that it can fit tightly with the steering shaft of the electric vehicle, thereby playing a sealing role, preventing dust and impurities from entering between the steering sleeve 2 and the steering shaft, causing wear and erosion, and reducing service life.

[0043] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
