Description

Technical Field

[0001] This utility model relates to an adjustable side-mounted motor, belonging to the technical field of side-mounted motors. Background Technology

[0002] A side-mounted motor is a drive device that mounts a motor to the side of a device. Electric motorcycles typically use side-mounted motors. Most side-mounted motors on the market have a non-adjustable mounting point. Different models have different wheelbases and battery box positions, so even modifying the dimensions of the swingarm bracket cannot change the motor's wheelbase. Most models are incompatible due to excessively large shock absorption angles, limiting the types of vehicles that can be fitted. This restricts compatibility and limits the range of vehicles that can be modified, failing to meet the modification needs of electric motorcycles. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an adjustable side-mounted motor with a wide range of applications.

[0004] To achieve this objective, the technical solution adopted by this utility model is:

[0005] An adjustable side-mounted motor includes a motor housing, a left connecting plate, a right connecting plate, and two rear shock absorber lugs for mounting rear shock absorbers. The left connecting plate is connected to the motor housing. Both the motor housing and the right connecting plate have multiple rows of horizontally arranged mounting holes. A first screw fixes the two rear shock absorber lugs into one row of mounting holes on the motor housing and the corresponding row of mounting holes on the right connecting plate, respectively. The motor housing also includes a first front fork, with its two ends mounted on the ends of the left and right connecting plates, respectively. Both the left and right connecting plates have multiple rows of longitudinally arranged fixing holes at their ends. A second screw passes through any row of fixing holes and is fixed to the first front fork.

[0006] As a further optimization of the above technical solution: the motor housing and the right connecting plate are both provided with three rows of mounting holes, each row having three holes. The three rows of mounting holes allow the opening of the rear shock absorber lugs to be adjusted between three distances: 200mm, 220mm, and 240mm.

[0007] As a further optimization of the above technical solution: the fixing holes are provided in two rows, and the two rows of fixing holes can meet the wheelbase requirements of 330mm and 360mm respectively.

[0008] As a further optimization of the above technical solution: the first front fork includes a fork fixing plate, two first front fork side plates located on the fork fixing plate, and a connecting shaft located between the two first front fork side plates. The two ends of the fork fixing plate are respectively fixed to the fixing holes of the left connecting plate and the right connecting plate. Both ends of the fork fixing plate are provided with several elongated movable holes. A third screw passes through the movable hole and can move laterally within the movable hole. The shank of the third screw is threaded to the first front fork side plate. The third screw fixes the first front fork side plate to the fork fixing plate. The head of the third screw is in close contact with the bottom surface of the fork fixing plate. Loosening the third screw causes the first front fork side plate to move relative to the fork fixing plate, adjusting the distance between the two first front fork side plates. The side of the fork fixing plate is also provided with scale lines. The two ends of the connecting shaft pass through the two first front fork side plates respectively. When the two first front fork side plates move relative to the fork fixing plate, they also move relative to the connecting shaft.

[0009] As a further optimization of the above technical solution: the motor windings are made of flat wire.

[0010] As a further optimization of the above technical solution, an ABS sensor is also included, which is fixed on the right connecting plate.

[0011] As a further optimization of the above technical solution: the right connecting plate is connected to the motor shaft by a double-row angular contact ball bearing.

[0012] As a further optimization of the above technical solution: a second front fork is included, the second front fork including a fork cross plate, two fork connecting blocks and two second front fork side plates, the two fork connecting blocks are respectively fixed to the ends of the left connecting plate and the right connecting plate, the fork cross plate is fixed on the top of the two fork connecting blocks and located above the left connecting plate and the right connecting plate, and the two fork side plates are respectively fixed to both ends of the fork cross plate.

[0013] Compared with existing technologies, this utility model, by setting multiple rows of mounting holes, allows for adjustable opening of the rear shock absorber hanger, enabling it to adapt to shock absorbers of different sizes, thus having a wide range of applications and accommodating more vehicle models. Simultaneously, the screw installation facilitates the disassembly and replacement of the rear shock absorber hanger, ensuring compatibility between the shape of the rear shock absorber hanger and the rear shock absorber. The multiple rows of longitudinally arranged fixing holes provide multiple mounting positions on the left and right connecting plates for mates with the first front horizontal fork, facilitating adjustment of the first front horizontal fork's mounting position on the left and right connecting plates as needed, i.e., adjusting the wheelbase of the side-mounted motor to adapt to different vehicle models; it can also... The fork connecting block in the second front fork can be replaced according to the required wheelbase to meet the needs of a larger wheelbase; loosening the third screw will loosen the fit between the first front fork side plate and the front fork fixing plate, allowing the first front fork side plate to move relative to the front fork fixing plate, adjusting the distance between the two first front fork side plates to adapt to different vehicle models, with a wide range of applications; the motor winding uses flat wire, which can obtain high power density and torque density, ensuring high efficiency and excellent heat dissipation, and low vibration and noise; the ABS sensor is directly mounted on the right connecting plate, reducing installation errors and ensuring accurate installation and sensing.

[0016] Figure 3 This is a three-dimensional structural diagram of Embodiment 2 of this utility model. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1:

[0019] like Figure 1-2As shown, an adjustable side-mounted motor includes a motor housing 8, a left connecting plate 1, a right connecting plate 2, and two rear shock absorber hangers 9 for mounting the rear shock absorber. The left connecting plate 1 is connected to the motor housing 8. Both the motor housing 8 and the right connecting plate 2 have multiple rows of horizontally arranged mounting holes 4. A first screw fixes the two rear shock absorber hangers 9 into one row of mounting holes 4 on the motor housing 8 and the corresponding row of mounting holes 4 on the right connecting plate 2, respectively. Both the motor housing 8 and the right connecting plate 2 have three rows of three mounting holes 4 each. The arrangement of these three rows of mounting holes 4 allows for adjustment of the rear shock absorber hanger spacing. The rear shock absorber hanger spacing refers to the installation distance at the connection between the rear shock absorber and the vehicle frame, i.e., the width between the two hangers. In this invention, the rear shock absorber hanger spacing can be adjusted between three distances: 200mm, 220mm, and 240mm, adapting to rear shock absorbers of different sizes and having a wide range of applications. Three mounting holes per row ensure the installation strength of the rear shock absorber hanger. Screw installation facilitates the disassembly and replacement of the rear shock absorber hanger, ensuring a proper fit between the shape of the rear shock absorber hanger and the rear shock absorber. For example... Figure 1 The rear shock absorber hanger can be adapted to rear shock absorbers with a U-shaped connection structure. When the rear shock absorber does not have a U-shaped connection structure, the rear shock absorber hanger can be removed and replaced with a U-shaped rear shock absorber hanger.

[0020] The above technical solution also includes a first front flat fork 3, with its two ends respectively installed on the ends of the left connecting plate 1 and the right connecting plate 2. Both the left connecting plate 1 and the right connecting plate 2 have multiple rows of longitudinally arranged fixing holes 5. A second screw passes through any row of fixing holes 5 and is fixed to the first front flat fork 3. The multiple rows of longitudinally arranged fixing holes 5 provide multiple mounting positions on the left connecting plate 1 and the right connecting plate 2 that mate with the first front flat fork 3, facilitating adjustment of the mounting position of the first front flat fork 3 on the left connecting plate 1 and the right connecting plate 2 as needed, i.e., adjusting the wheelbase of the side-mounted motor. In this invention, two rows of fixing holes 5 are provided, which can respectively meet the wheelbase requirements of 330mm and 360mm, achieving two-stage wheelbase adjustment.

[0021] In the above technical solution: the first front fork 3 includes a fork fixing plate 31, two first front fork side plates 32 located on the fork fixing plate 31, and a connecting shaft 33 located between the two first front fork side plates 32. The two ends of the fork fixing plate 31 are respectively fixed to the fixing holes 5 of the left connecting plate 1 and the right connecting plate 2. Several elongated movable holes 34 are formed at both ends of the fork fixing plate 31. A third screw passes through the movable hole 34 and can move laterally within the movable hole 34. The shank of the third screw is threadedly fixed to the first front fork side plate 32, thus fixing the first front fork side plate 32 to the fork fixing plate 31. The head of the third screw is in close contact with the bottom surface of the fork fixing plate 31. Loosening the third screw loosens the fit between the first front fork side plate 32 and the fork fixing plate 31, allowing the first front fork side plate 32 to move relative to the fork fixing plate 31, adjusting the distance between the two first front fork side plates 32. The side of the fork fixing plate 31 is also provided with scale lines, which make it easy to clearly see the moving distance of the first fork side plate 32. The two ends of the connecting shaft 33 are respectively inserted into the two first fork side plates 32. When the two first fork side plates 32 move relative to the fork fixing plate 31, they also move relative to the connecting shaft 33.

[0022] In the above technical solution, the motor winding uses flat wire 10, meaning the power source of this utility model is a flat wire motor. Using flat wire 10 in the motor winding has the following advantages: 1. High power density and torque density can be obtained because the slot fill factor is increased by 20%-30%, and copper loss is reduced by 10%-30%; 2. High efficiency: in the 20%-80% load range of the main driving range of electric vehicles, motor efficiency can be increased by 1-3%, directly extending the driving range; 3. Excellent heat dissipation capacity: the large contact area between the flat wires allows heat to be directly conducted to the stator core through the copper wire, reducing thermal resistance; 4. Low vibration and noise: after the flat wires are cured, they form a "honeycomb structure," increasing the overall rigidity of the stator, suppressing electromagnetic vibration, and reducing noise.

[0023] The above technical solution also includes an ABS sensor 6, which is fixed on the right connecting plate 2. In the prior art, the ABS sensor is mounted on an adapter, but the adapter is mounted on multiple components using multiple screws, leading to installation errors that can accumulate. The adapter is also prone to lateral movement, resulting in poor installation accuracy and sensor sensing accuracy. In contrast, the ABS sensor of this invention is directly mounted on the right connecting plate 2, ensuring precise installation and accurate sensing.

[0024] In the above technical solution: the right connecting plate 2 is connected to the motor shaft by a double-row angular contact ball bearing 7. The double-row angular contact ball bearing has the advantages of being able to withstand radial loads and bidirectional axial loads, as well as high rigidity.

[0025] Example 2:

[0026] This embodiment is largely similar to the previous embodiment in terms of technical solution. The differences will be described in detail below, while the contents that are the same in both will not be repeated here.

[0027] like Figure 3 As shown, the device includes a second front fork 11, which comprises a fork crossplate 112, two fork connecting blocks 111, and two second front fork side plates 113. The two fork connecting blocks 111 are fixed to the ends of the left connecting plate 1 and the right connecting plate 2, respectively. The fork crossplate 112 is fixed on top of the two fork connecting blocks 111 and is located above the left connecting plate 1 and the right connecting plate 2. The two front fork side plates 113 are fixed to both ends of the fork crossplate 112, respectively. In this embodiment, the fork connecting blocks 111 of different heights can be replaced according to the required wheelbase to meet the needs of a larger wheelbase; the wheelbase in this embodiment is 380mm.

[0028] This utility model, by setting multiple rows of mounting holes 4, allows for adjustable opening of the rear shock absorber hanger, enabling it to adapt to shock absorbers of different sizes, thus having a wide range of applications and accommodating more vehicle models. Simultaneously, the screw installation facilitates the disassembly and replacement of the rear shock absorber hanger, ensuring compatibility between the shape of the rear shock absorber hanger and the rear shock absorber. The multiple rows of longitudinally arranged fixing holes 5 provide multiple mounting positions on the left connecting plate 1 and right connecting plate 2 for mates with the first front horizontal fork 3, facilitating adjustment of the mounting position of the first front horizontal fork 3 on the left and right connecting plates 1 and 2 as needed, i.e., adjusting the wheelbase of the side-mounted motor to adapt to different vehicle models; it also allows for the installation of the second front horizontal fork 11. The front fork connecting block 111 can be replaced according to the required wheelbase to meet the needs of a larger wheelbase; loosening the third screw will loosen the fit between the first front fork side plate 32 and the front fork fixing plate 31, allowing the first front fork side plate 32 to move relative to the front fork fixing plate 31, adjusting the distance between the two first front fork side plates 32 to adapt to different vehicle models, with a wide range of applications; the motor winding uses flat wire 10, which can obtain high power density and torque density, ensuring high efficiency and excellent heat dissipation capacity, and low vibration and noise; the ABS sensor is directly installed on the right connecting plate 2, reducing installation errors and ensuring accurate installation and sensing.

[0029] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should fall within the protection scope of this utility model.
