Description

Technical Field

[0001] This utility model relates to the field of all-terrain vehicle manufacturing technology, and in particular to an all-terrain vehicle power mechanism and an all-terrain vehicle. Background Technology

[0002] All-terrain vehicles (ATVs) are vehicles capable of traversing any terrain, moving freely on surfaces where ordinary vehicles struggle. The English term is All Terrain Vehicle (ATV), also known as an "all-terrain four-wheel off-road vehicle." These vehicles are simple, practical, and have excellent off-road performance. ATVs generate greater friction with the ground and reduce the vehicle's pressure on the ground, making them easy to travel on beaches, riverbeds, forest trails, streams, and harsh desert terrain. They can carry people or transport goods. With the global trend towards electrification, the electrification of ATVs has become an unstoppable development trend under the call for energy conservation and emission reduction. However, the electrification of ATVs means that in addition to traditional drive and transmission systems, they also need battery packs to store energy. Furthermore, the longer the range of an ATV, the larger and heavier the battery packs will be. Assembling these components on the frame of a traditional ATV is crucial for the range and lightweight design of electric ATVs.

[0003] In existing technologies, motors are generally mounted longitudinally on the vehicle frame. The transmission between the motor and the transmission box inevitably uses bevel gears, resulting in a high center of gravity for the vehicle body. Bevel gear transmissions are inefficient and noisy. The transmission box is vertically arranged, which also results in a high center of gravity for the vehicle body. It requires forced lubrication with an oil pump, which is complex and costly. The charging socket is usually located at the front or rear of the vehicle, which is too low. This leads to poor wading performance and the charging socket is easily damaged in a collision. The power battery is located in the vehicle body, and the charging socket is located at the front or rear of the vehicle, which is far from the power battery. This results in long charging lines, high costs, and low efficiency.

[0004] Therefore, there is an urgent need for an all-terrain vehicle power system and an all-terrain vehicle. Improving the power structure of electric all-terrain vehicles can enhance the transmission efficiency of all-terrain vehicles, enable torque distribution flexibility and multi-mode drive selection, lower the center of gravity of the vehicle, improve the handling stability of the vehicle, enhance the wading performance and safety of the vehicle, change the cable layout of the power source, and reduce the overall cost of the vehicle.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 This is a top view of the present invention. Figure 3 This is a bottom view of the present invention, as shown below. Figure 1 As shown:

[0026] The all-terrain vehicle power mechanism and all-terrain vehicle of this embodiment include: a frame 1, which provides support for the all-terrain vehicle and provides mounting positions for the components of the all-terrain vehicle; the mounting positions refer to the installation space and positions reserved for the components of the all-terrain vehicle to ensure that they can be adapted and installed correctly; the design of the mounting positions will take into account the matching with the component interfaces, including mechanical connection methods such as bolt holes, connecting surfaces, and positioning pins, which will not be described in detail here.

[0027] A power source, mounted on the frame 1, includes a power battery 3 and a transmission box, which is horizontally arranged on the frame 1. The power source typically refers to an integrated system, generally including a drive motor, controller, and gearbox or other mechanical components, used to provide power to the all-terrain vehicle. The transmission box is horizontally arranged on the frame 1 via a mounting position. Horizontal arrangement means that the transmission box is horizontally mounted on the frame 1. The connection between the transmission box and the frame 1 can be directly secured to the frame with bolts, providing sufficient rigidity and stability. Alternatively, lugs can be used as mounting positions for the transmission box, suspending it on the frame 1, facilitating installation and disassembly while providing flexibility. Other mechanical connection methods can also be used between the transmission box and the frame 1, which will not be elaborated here.

[0028] In this embodiment, the power battery 3 can be installed on the frame 1 from the bottom upwards and near the middle. Installing the power battery 3 from the bottom of the all-terrain vehicle facilitates maintenance and replacement, and also allows for separate transport of the all-terrain vehicle and the power battery 3. The power battery 3 can be replaced without disassembling other parts of the vehicle. Installing the power battery 3 near the middle of the frame 1 helps lower the vehicle's center of gravity, thereby improving driving stability and handling, achieving a more even weight distribution, and enhancing the vehicle's balance and traction. Installing the power battery 3 at the bottom of the frame 1 also simplifies electrical connections with the motor and controller, shortens cable length, reduces wiring complexity, and provides more freedom in vehicle design. Designers can flexibly adjust the design of the frame 1 according to the shape and size of the power battery 3.

[0029] In this embodiment, the power source further includes a power motor set, which includes a front drive motor set and a rear drive motor set; the front drive motor set includes a front drive motor 501 and a front controller 401, and the rear drive motor set includes a rear drive motor 502, a rear controller 402, and so on; Figure 1As shown, the front drive motor is installed at the front of the frame 1, and the rear drive motor is installed at the rear of the frame 1. The all-terrain vehicle adopts independent drive of front and rear dual motors, namely the front drive motor and the rear drive motor. Independent drive of dual motors allows for more flexible power distribution. The driver can transmit power to the front wheels, rear wheels, or all four wheels simultaneously as needed, providing better traction and stability. The power distribution is flexibly controlled by the front controller 401 and the rear controller 402 of the vehicle, which can adapt to various working conditions and ensure that the front and rear motors always work in the high-efficiency range, achieving the purpose of energy saving. The all-terrain vehicle adopts dual motors, and there is no transmission rod between the front wheel axle and the rear wheel axle, which can provide installation space for the power battery 3, realize the central placement of the power battery 3, and can be installed on the frame 1 from bottom to top.

[0030] In this embodiment, the front controller 401 is located between the front drive motor 501 and the power battery 3, and is mounted on the frame 1 close to the power battery 3. The rear controller 402 is integrated on the top of the rear drive motor 502. The front controller 401 and the front drive motor 501 are mounted on the same side of the frame 1, which can reduce the distance between them and reduce the length of the cable 2 between the front controller 401 and the front drive motor 501. The rear controller 402 and the rear drive motor 502 are directly connected internally using copper busbars instead of cables 2. The rear controller 402 and the rear drive motor 502 can be mounted on the top of the rear drive motor 502 by bolt connection.

[0031] In this embodiment, the transmission box includes a front transmission box 601 and a rear transmission box 602, and the output terminals of the front drive motor 501 and the rear drive motor 502 are respectively connected to the input terminals of the front transmission box 601 and the rear transmission box 602; as Figure 1 As shown, the horizontal arrangement of the front transmission case 601 and the rear transmission case 602 helps to lower the vehicle's center of gravity, reduce vibrations caused by the transmission system, improve ride comfort, driving stability and handling, make the transmission system more compact, save internal space of the frame 1, and facilitate overall layout and design. Compared with the vertical arrangement, the horizontal arrangement simplifies the structure of the transmission system and reduces the number and complexity of components. The horizontal arrangement of the front transmission case 601 and the rear transmission case 602 is easy to replace and maintain because their installation position is low, making it convenient for technicians to inspect and repair.

[0032] During use, the transmission box requires oil lubrication. Oil lubrication refers to the method of lubrication that uses oil to reduce friction, wear, and overheating between mechanical parts. The oil can form a thin film, reducing direct contact between internal parts of the transmission box and lowering the coefficient of friction. The transmission box generates heat during operation, which the oil can absorb and carry away to prevent overheating. If the front transmission box 601 and the rear transmission box 602 are arranged vertically, the lubricating oil and coolant in the transmission box will naturally flow to the oil pan due to gravity, requiring an additional oil pump for forced lubrication. However, a horizontal arrangement can improve the lubrication conditions of the front transmission box 601 and the rear transmission box 602. The oil can directly lubricate the mechanical parts through splashing, reducing the need for oil circulation. The oil will not concentrate at the bottom of the box due to gravity, reducing the internal pressure of the transmission box. A horizontal arrangement of the transmission box can also help dissipate heat. The horizontal arrangement allows the transmission box to have a larger surface area, which is conducive to heat dissipation. Compared with a vertical arrangement, a horizontal arrangement of the transmission box helps to lower the overall center of gravity of the vehicle, helps to balance the weight distribution of the vehicle, and improves the driving safety of the vehicle.

[0033] In this embodiment, the frame 1 includes a pair of upper longitudinal beams 101 and a pair of lower longitudinal beams 102. The spacing of the lower longitudinal beams 102 near the middle is greater than the spacing of the upper longitudinal beams 101, which is used to provide a mounting position for the power battery 3. A charger 7 is mounted on the frame 1 above the front controller 401. The charger 7 has a charging socket 8 that extends above the top of the charger 7 on the side near the power battery 3. The charger 7 is mounted above the front controller 401. Since the power battery 3 is located near the middle, and the front controller 401 is located between the front drive motor 501 and the power battery 3, and is mounted on the frame 1 near the power battery 3, the charging socket 8 of the charger 7 can be located near the seat of the all-terrain vehicle. The overall position of the charger 7 and the charging socket 8 is relatively high, which improves the wading performance. In addition, the charging socket 8 is close to the charger 7 and the power battery 3, requiring a shorter cable 2, thus reducing costs.

[0034] The front controller 401 is located between the front drive motor 501 and the power battery 3, and is mounted on the frame 1 close to the power battery 3. The rear controller 402 is integrated on top of the rear drive motor 502. A charger 7 is mounted on the frame 1 above the front controller 401. The front controller 401 and the front drive motor 501 are mounted on the same side of the frame 1, which can reduce the distance between them and reduce the length of the cable 2 between the front controller 401 and the front drive motor 501. However, the overall weight of the front end of the vehicle is relatively large. The power battery 3 is set close to the center. Setting close to the center means that the power battery 3 is installed in the middle of the frame 1 but biased towards the rear of the frame 1, which can ensure that the overall weight of the vehicle is evenly distributed.

[0035] In this embodiment, the front drive motor 501 and the rear drive motor 502 are transversely mounted on the frame 1 and fixed through corresponding mounting positions on the frame 1. The transverse layout of the front drive motor 501 and the rear drive motor 502 more effectively utilizes the vehicle's lateral space, helping to achieve a balance in the vehicle's front and rear weight. The transverse placement of the front drive motor 501 and the rear drive motor 502, along with the two-stage cylindrical gear reduction gearbox between the drive motors and the transmission, avoids bevel gear transmission, effectively improving transmission efficiency and reducing noise generation. Figure 1 As shown, the empty space in front of the front drive motor 501 can be used to install a winch 9, making the overall structure of the all-terrain vehicle more compact.

[0036] In this embodiment, the upper longitudinal beam 101 is provided with a crossbeam with a wire clamp at the front of the frame 1. The wire clamp is installed at the end of the crossbeam on the same side as the front drive motor 501 and is used to fix the cable 2 between the front motor controller and the front drive motor 501. The wire clamp is on the same side as the front drive motor 501, which can ensure that the wire clamp, the front drive motor 501, and the front controller 401 are all located on the same side of the frame 1. When controlling the length of the cable 2 between the front controller 401 and the front drive motor 501, the cable 2 needs to be routed due to the influence of the vehicle's shock absorption movement space. Therefore, the wire clamp is needed to fix the cable 2.

[0037] In this embodiment, an all-terrain vehicle is also provided. The all-terrain vehicle adopts the all-terrain vehicle power mechanism described above, which can improve the transmission efficiency of the all-terrain vehicle, realize the flexibility of torque distribution and the selection of multiple driving modes. The power battery 3 is set close to the middle and installed from bottom to top, which lowers the center of gravity of the vehicle, facilitates assembly, improves the handling stability of the vehicle, enhances the wading performance and safety of the vehicle, and reduces the cost of the vehicle.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
