Description

Technical Field

[0001] This utility model relates to the field of electric tricycle technology, and in particular to a motor mounting bracket for electric tricycles. Background Technology

[0002] Electric tricycles are three-wheeled transportation vehicles powered by electricity. With the increasing popularity of electric tricycles, the market demands for their performance, stability, and reliability are rising. As a new type of urban short-distance transportation tool, electric tricycles are widely used in delivery, passenger and cargo transportation, and other fields. The motor is the core of the electric tricycle's power, and the design and manufacturing of its mounting bracket directly affect the performance and service life of the electric tricycle. Therefore, a motor mounting bracket for electric tricycles is needed.

[0003] Currently, the motor mounting brackets and hub motors of existing electric tricycles on the market are usually installed by locking multiple bolts and nuts. When the hub motor malfunctions and needs to be repaired, the user must use professional tools to remove multiple bolts and nuts one by one. When reinstalling, multiple bolts and nuts need to be tightened one by one, which increases the difficulty of operation for the user, and takes a lot of time, reducing work efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a motor mounting bracket for electric tricycles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A motor mounting bracket for an electric tricycle includes two mounting seats. The inner sidewalls of the two mounting seats are provided with a common connecting seat, and both ends of the connecting seat are rotatably connected to the two mounting seats respectively. A support frame is fixed to the top of the connecting seat. Brake pads are provided on the inner sidewalls of both ends of the two mounting seats, and one end of each brake pad is fixed to the two mounting seats respectively. A hub motor is provided on the outer sidewall of each of the two brake pads, and the output shafts of the two hub motors pass through the inner sidewalls of the two brake pads respectively. A limiting mechanism for restricting the output shafts of the hub motors is provided on the sidewalls of the output shafts of the two hub motors. A fixing mechanism is provided on the sidewalls of the output shafts of the two hub motors. Two dampers are symmetrically arranged at one end of the top of the support frame, and damping springs are sleeved on the outer sidewalls of both dampers. Each damper has a second ring fixed to its bottom, and a first ring fixed to one end of each output shaft. Both ends of the support frame have connecting mechanisms for connecting the two dampers. During use, the design of the limiting and fixing mechanisms allows for quick installation or disassembly of the hub motor without the need for bolts, nuts, or other fasteners, significantly improving operational convenience. The simplified installation and disassembly process allows operators to complete tasks in less time, saving time and increasing work efficiency. The connecting mechanism design also enables rapid installation or disassembly of the shock absorption system, simplifying maintenance and inspection. Operators can more easily perform regular checks and maintenance, enhancing the practicality of the device.

[0007] As a further embodiment of this utility model, the limiting mechanism includes a limiting ring, which is sleeved on the side wall of the output shaft of one of the hub motors and located outside one of the brake pads. Two protrusions are symmetrically fixed on the inner side wall of the limiting ring, and two limiting grooves are formed on the outer side wall of one of the brake pads. The two limiting grooves are respectively adapted to the two brake pads. The output shaft of the hub motor is inserted into the brake pad until the two protrusions enter the two limiting grooves respectively, thereby limiting the output shaft of the hub motor and preventing the output shaft of the hub motor from rotating.

[0008] As a further embodiment of this utility model, the fixing mechanism includes an annular plate, which is sleeved on the side wall of one of the hub motor output shafts and located inside one of the brake pads. Two sleeves are symmetrically fixed to the outer wall of the annular plate. A second circular slider is slidably connected to the inner wall of each of the two sleeves. A second locking pin is fixed to one end of each of the two second circular sliders, with one end of each second locking pin penetrating one end of the outer wall of one end of each of the two sleeves and also penetrating the inner wall of the annular plate. A pull rod is fixed to the other end of each of the two second circular sliders, with one end of each pull rod penetrating the other end of the outer wall of the sleeve. A second return spring is sleeved on the side wall of each of the two pull rods. Two grooves are symmetrically formed on the side wall of the output shaft of one of the hub motors, and the two grooves and the two second locking pins are connected to each other. In a one-to-one correspondence, by pulling the two levers, the two second circular sliders move away from each other along the inner walls of the two sleeves until the two second locking pins retract into the two sleeves. At this point, both second return springs are in a compressed state. Then, the annular plate is placed on the output shaft of the hub motor. When one end of the annular plate is in contact with the inner wall of one of the brake pads, the two second locking pins are in an overlapping state with the two grooves. At this point, the two levers are released. Under the reaction force of the two compressed second return springs, the two second circular sliders are pushed to move in the opposite direction, thereby pushing one end of the two second locking pins into the two grooves. This completes the installation of the hub motor. During the process, there is no need to install it by tightening bolts and nuts. The operation is simple and convenient for installing or disassembling the hub motor, while saving a lot of time and improving work efficiency.

[0009] As a further embodiment of this utility model, the connecting mechanism includes two connecting shafts, which are respectively disposed on the inner sidewalls of the first and second sleeve rings. Both ends of the two connecting shafts are provided with sliding grooves, and all four sliding grooves are constricted structures. A first circular slider is slidably connected to the inner sidewall of each of the four sliding grooves. A first locking post is fixed to one end of each of the four first circular sliders. A first return spring is disposed inside each of the four sliding grooves, and the four first return springs are respectively located at the other end of each of the four first circular sliders. A first U-shaped plate is fixed to one end of the top of the support frame. A first circular hole is provided on each of the two symmetrical outer sidewalls of the first U-shaped plate, and two of the first circular holes are respectively adapted to two of the first locking posts. The tricycle... A second U-shaped plate is fixed to one side of the bottom of the compartment. The two outer side walls of the second U-shaped plate are provided with second circular holes, and the two second circular holes are respectively adapted to the other two first locking pins. By pressing the four first locking pins, the four first circular sliders move closer to each other along the inner side walls of the four slide grooves until the four first locking pins are retracted into the four slide grooves. At this time, the four first locking pins are disengaged from the two circular holes and the two second circular holes, and the damper, damping spring, first collar, second collar and two connecting shafts can be taken out as a whole. The operation is simple and convenient for the installation and replacement of the shock absorption system, making the maintenance and inspection process simple. Operators can more easily perform regular inspections and maintenance, which improves the practicality of this device.

[0010] As a further embodiment of this utility model, the upper and lower ends of the inner sidewalls of the two mounting bases are fixed with support plates, the four support plates are in pairs, and the same bolt is installed through each pair of support plates. One end of each bolt is fitted with a nut, and the two nuts are respectively adapted to the two bolts.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. During use, this device, through the design of the limiting and fixing mechanisms, can quickly complete the installation or disassembly of the hub motor. The installation process does not require the use of fasteners such as bolts and nuts, which significantly improves the convenience of operation. Because the installation and disassembly process is simplified, operators can complete the work in a shorter time, saving more time and improving work efficiency.

Hub motors 3 are provided on the outer walls of both brake pads 6, and the output shafts of the two hub motors 3 pass through the inner walls of the two brake pads 6 respectively. A limiting mechanism for restricting the output shafts of the hub motors 3 is provided on the side walls of the two brake pads 6. A fixing mechanism is provided on the side walls of the output shafts of the two hub motors 3. Two dampers 9 are symmetrically arranged at one end of the top of the support frame 2, and damping springs 10 are sleeved on the outer walls of both dampers 9. Each damper 9 has a second ring 12 fixed to its bottom, and each of the two dampers 9 has a first ring 11 fixed to one end of its output shaft.

Through the design of the connecting mechanism, the shock absorption system can be quickly installed or removed, making the maintenance and inspection process simple. Operators can more easily perform regular inspections and maintenance, which improves the practicality of the device.

[0024] In this embodiment, the limiting mechanism includes a limiting ring 19, which is sleeved on the side wall of the output shaft of one of the hub motors 3 and located outside one of the brake pads 6.

Two limiting grooves 7 are opened on the outer side wall of one of the brake pads 6, and the two limiting grooves 7 are respectively adapted to the two brake pads 6. The output shaft of the hub motor 3 is inserted into the brake pad 6 until the two protrusions 20 enter the two limiting grooves 7 respectively, thereby limiting the output shaft of the hub motor 3 and preventing the output shaft of the hub motor 3 from rotating.

[0025] In this embodiment, the fixing mechanism includes an annular plate 22, which is sleeved on the side wall of the output shaft of one of the hub motors 3 and located inside one of the brake pads 6.

The mechanism is activated by pulling... Move the two pull rods 26 to make the two second circular sliders 24 move away from each other along the inner walls of the two sleeves 23 until the two second locking pins 25 retract into the two sleeves 23. At this time, the two second return springs 27 are in a compressed state. Then, put the annular plate 22 on the output shaft of the hub motor 3. When one end of the annular plate 22 is in contact with the inner wall of one of the brake pads 6, the two second locking pins 25 are in an overlapping state with the two grooves 21. At this time, release the two pull rods 26. Under the reaction of the two compressed second return springs 27, push the two second circular sliders 24 to move in the opposite direction, thereby pushing one end of the two second locking pins 25 into the two grooves 21. The installation of the hub motor 3 can be completed. During the process, there is no need to install it by tightening bolts and nuts. The operation is simple and convenient for installing or disassembling the hub motor 3. At the same time, it saves a lot of time and improves work efficiency.

[0026] In this embodiment, the connecting mechanism includes two connecting shafts 13, which are respectively disposed on the inner sidewalls of the first collar 11 and the second collar 12. Both ends of the two connecting shafts 13 are provided with sliding grooves 14, and all four sliding grooves 14 are constricted structures. The inner sidewalls of the four sliding grooves 14 are slidably connected to first circular sliders 15. One end of each of the four first circular sliders 15 is fixed with a first locking post 16. Each of the four sliding grooves 14 contains a first return spring 17, which is located at the other end of each of the four first circular sliders 15. A first U-shaped plate 4 is fixed to one end of the top of the support frame 2. The two outer sidewalls of the first U-shaped plate 4 are symmetrically provided with first circular holes 8, and two of the first circular holes 8 are respectively adapted to two of the first locking posts 16. A first U-shaped plate 4 is fixed to one side of the bottom of the tricycle carriage. The second U-shaped plate 5 has two symmetrical outer side walls with second circular holes, and each of the two second circular holes is adapted to the other two first locking posts 16. By pressing the four first locking posts 16, the four first circular sliders 15 move closer to each other along the inner side walls of the four slide grooves 14 until the four first locking posts 16 are retracted into the four slide grooves 14. At this time, the four first locking posts 16 are disengaged from the two first circular holes 8 and the two second circular holes, and the damper 9, damping spring 10, first collar 11, second collar 12 and two connecting shafts 13 can be taken out as a whole. The operation is simple, which makes it easy to install and replace the shock absorption system, and makes the maintenance and inspection process simple. Operators can more easily carry out regular inspections and maintenance, which improves the practicality of the device.

[0027] In this embodiment, support plates 29 are fixed at both the upper and lower ends of the inner sidewalls of the two mounting bases 1. The four support plates 29 are in pairs, and the same bolt 28 is provided through each pair of support plates 29. Nuts 31 are fitted on one end of each bolt 28, and the two nuts 31 are respectively adapted to the two bolts 28.

[0028] Working principle: During use, the limiting ring 19 is pre-fitted onto the side wall of the output shaft of the hub motor 3. During installation, the output shaft of the hub motor 3 is inserted into the brake pad 6 until the two protrusions 20 enter the two limiting grooves 7 respectively, limiting the output shaft of the hub motor 3 and preventing it from rotating. At this time, the two pull rods 26 are pulled, causing the two second circular sliders 24 to move away from each other along the inner side walls of the two sleeves 23 until the two second locking pins 25 retract into the two sleeves 23 respectively. At this point, both second return springs 27 are in a compressed state. Then, the annular plate 22 is fitted onto the output shaft of the hub motor 3. When one end of the annular plate 22 is in contact with the inner wall of one of the brake pads 6, the two second locking pins 25 are aligned with the two grooves 21 respectively. At this time, releasing the two pull rods 26 causes the two second circular sliders 24 to move in the opposite direction under the reaction force of the two compressed second return springs 27. This pushes one end of each of the two second locking pins 25 into the two grooves 21, thus completing the operation of the hub motor 3. The installation process is simple and does not require bolt and nut tightening, making it easy to install or remove the hub motor 3. This saves time and improves work efficiency. When the shock absorption system needs to be replaced, press the four first locking posts 16, causing the four first circular sliders 15 to move closer together along the inner walls of the four sliding grooves 14 until the four first locking posts 16 retract into the four sliding grooves 14. At this point, the four first locking posts 16 are respectively aligned with the two first circular holes 8 and the two second circular holes. Once disengaged, the damper 9, damping spring 10, first collar 11, second collar 12, and two connecting shafts 13 can be removed as a whole. After replacing the damper 9, damping spring 10, first collar 11, and second collar 12 with new ones, the two connecting shafts 13 can be reinserted into the first collar 11 and second collar 12 respectively for installation. The operation is simple, making it easy to install and replace the shock absorption system, simplifying the maintenance and inspection process. Operators can more easily perform regular inspections and maintenance, thus improving the practicality of the device.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
