Description

Technical Field

[0001] The utility model relates to the field of electric vehicles, in particular to a reducer protection device based on shock absorption of electric vehicles. Background Art

[0002] The electric vehicle reducer is a mechanical transmission device used to reduce the output speed of the drive device and increase the output torque to drive the vehicle. The reducer protection device based on electric vehicle shock absorption is intended to protect the reducer system of the electric vehicle, extend its service life and improve the performance and safety of the vehicle. The existing reducer shock absorption devices include spring shock absorbers, shock absorber brackets and other shock absorption forms, but there is hard contact between these shock absorption devices and the reducer, the shock absorption effect is not obvious and it is easy to cause damage to the reducer and shock absorption device.

[0003] Therefore, a reducer protection device based on electric vehicle shock absorption is now developed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of hard contact between the existing device and the reducer, unclear shock absorption effect and easy damage to the reducer and the shock absorption device, the utility model provides a reducer protection device based on shock absorption of an electric vehicle.

[0005] The technical solution of the utility model is: a reducer protection device based on shock absorption of electric vehicles, comprising a base, guide frames are arranged on the upper parts of the left and right sides of the base, buffer rods are arranged on the upper parts of the front sides of the guide frames, buffer springs are connected between the front sides of the guide frames and the adjacent buffer rods, buffer mechanisms are arranged on the middle parts of the front sides of the guide frames, the buffer mechanisms comprise mounting frames, the middle parts of the front sides of the guide frames are connected to the mounting frames, air intake airbags are arranged on the mounting frames, pressure relief valves are arranged on the air intake airbags, air storage tanks are arranged on the upper parts of the air intake airbags, the front ends of the air storage tanks are connected to connecting pipes, the front ends of the connecting pipes are connected to buffer airbags, and the rear parts of the buffer airbags are connected to the buffer rods.

[0006] As a preferred embodiment of the utility model, the cable tie mechanism includes a sliding frame, five sliding frames are slidably connected to the upper part of the base, a lifting frame is slidably connected to the sliding frame, the sliding frames are slidably connected to the adjacent lifting frames with adjustment pins, and the upper part of the lifting frames is slidably connected to a cable tie.

[0007] As a preferred embodiment of the present invention, bolts are provided on both left and right sides of the bottom of the base to connect with the vehicle-mounted reducer.

[0008] As a preferred embodiment of the present invention, the buffer rod is provided with a limiting plate.

[0009] As a preferred embodiment of the present invention, the top of the lifting frame is arc-shaped.

[0010] As a preferred embodiment of the present invention, the buffer rod has a telescopic structure.

[0011] By adopting the above technical solution, the utility model has the following beneficial effects:

[0012] 1. The utility model installs the device outside the electric vehicle reducer. When the vehicle is started, the air intake airbag is opened, and the air pressure is stored in the air tank. The air pressure is transmitted to the buffer airbag through the connecting pipe, so that the buffer airbag expands. The buffer airbag contacts the outside of the electric vehicle reducer. As the buffer airbag continues to expand, it squeezes the buffer rod inward, causing the buffer rod to shrink. The limit plate on the front side of the buffer rod squeezes the buffer spring inward, so that the reducer obtains a better shock absorption effect under the dual action of the buffer airbag and the buffer spring, thereby protecting the reducer.

[0013] 2. The device is provided with a cable tie mechanism. The lifting frame is adjusted to a suitable height by using an adjustment pin. The line passes through the lifting frame and is tidied by a cable tie. The sliding frame is slid to a suitable spacing. This operation can avoid the clutter of the reducer line, reduce the line jitter, and prevent the line from breaking free. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] A reducer protection device based on electric vehicle shock absorption, such as Figure 1, Figure 2 and Figure 3 As shown, it includes a base 1, and bolts are provided on the left and right sides of the bottom of the base 1 to connect with the vehicle-mounted reducer, and guide frames 2 are provided on the upper part of the left and right sides of the base 1, and buffer rods 3 are provided on the upper part of the front side of the guide frame 2. The buffer rods 3 are provided with limiting plates, and the buffer rods 3 have a telescopic structure. Buffer springs 4 are connected between the front side of the guide frame 2 and the adjacent buffer rods 3, and a buffer mechanism 5 is provided in the middle part of the front side of the guide frame 2. The buffer mechanism 5 includes a mounting frame 51, and the middle part of the front side of the guide frame 2 is connected to the mounting frame 51, and an air intake airbag 52 is installed on the mounting frame 51, and a pressure relief valve 5201 is provided on the air intake airbag 52, and an air storage tank 53 is installed on the upper part of the air intake airbag 52, and the front end of the air storage tank 53 is connected to a connecting pipe 54, and the front end of the connecting pipe 54 is connected to a buffer airbag 55, and the rear of the buffer airbag 55 is connected to the buffer rod 3.

[0022] It should be noted that the electric vehicle reducer is a mechanical transmission device used to reduce the output speed of the drive device and increase the output torque to drive the vehicle to run, and the reducer protection device based on electric vehicle shock absorption is intended to protect the reducer system of the electric vehicle, extend its service life and improve the performance and safety of the vehicle. First, the device is installed on the outside of the electric vehicle reducer. When the vehicle starts, the air intake airbag 52 is opened, and the air pressure is stored in the air tank 53. The air pressure is transmitted to the buffer airbag 55 through the connecting pipe 54, so that the buffer airbag 55 expands. The buffer airbag 55 contacts the outside of the electric vehicle reducer. As the buffer airbag 55 continues to expand, the buffer rod 3 is squeezed inwardly, causing the buffer rod 3 to shrink. The limit plate on the front side of the buffer rod 3 squeezes the buffer spring 4 inwardly, thereby playing a buffering and shock-absorbing role of the reducer due to the vibration of the vehicle. When the vehicle stops running, the pressure relief valve 5201 automatically opens to perform the pressure relief operation.

[0023] Example 2

[0024] On the basis of Example 1, Figure 1 and Figure 4 As shown, the cable tie mechanism 6 includes a sliding frame 61, five sliding frames 61 are slidably connected to the upper part of the base 1, and a lifting frame 62 is slidably connected to the sliding frame 61. The top of the lifting frame 62 is arc-shaped, and the sliding frames 61 are slidably connected to the adjacent lifting frames 62 with adjustment pins 64, and the upper part of the lifting frames 62 is slidably connected to a cable tie 63.

[0025] It should be noted that in order to avoid the reducer line being messy, the device is provided with a wire harness mechanism 6. The lifting frame 62 is adjusted to a suitable height by using the adjustment pin 64. The line passes through the lifting frame 62 and is tidied by the wire tie 63. The sliding frame 61 is slid to a suitable spacing. This operation can reduce the line jitter and prevent the line from breaking free.

[0026] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
