Description

Technical Field

[0001] The utility model relates to the technical field of battery assembly, in particular to a battery connection device for a four-wheel eight-drive robot. Background Art

[0002] Mobile robotics technology has made significant progress in recent years, finding widespread application in agriculture, mining, military, and rescue operations. Demand for highly flexible and adaptable mobile robots is growing, particularly in complex terrain and high-load environments. Traditional two- or four-wheel drive robots may not provide sufficient stability and traction in certain extreme environments, making them incapable of efficient mission execution. To address these challenges, the design of four-wheel, eight-wheel drive systems has become a hot topic.

[0003] The four-wheel, eight-wheel drive mobile robot is designed to improve its adaptability and flexibility in complex terrain by independently driving and controlling each wheel. Whether in rugged mountainous terrain or on wet and muddy ground, this robot can maintain excellent performance under high load conditions, showing broad application prospects.

[0004] Four-wheel, eight-wheel drive mobile robots, with their excellent maneuverability and powerful payload capacity, are ideal for complex tasks. Compared to traditional mechanical systems, their unique drive layout and structural design offer distinct advantages in off-roading, hill climbing, and carrying heavy loads. However, achieving these advantages requires overcoming multiple engineering challenges, including precise control of the drive system, lightweight and robust mechanical structures, and ensuring system stability and reliability over extended periods of operation.

[0005] However, in existing four-wheel eight-wheel drive robots, the battery is often designed in the middle of the robot body, taking up a large amount of space in the chassis, making the overall height of the robot too high and increasing the instability of the robot. Utility Model Content

[0006] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a battery connection device for a four-wheel eight-drive robot.

[0007] A battery connection device for a four-wheel, eight-wheel drive robot. The technical solution of this utility model is as follows:

[0008] A battery connection device for a four-wheel, eight-wheel drive robot. The robot comprises an upper main body and lower wheels including a backplate. The rear portion of the backplate is slidably connected to the outer side wall in the length direction of the main body. The upper and lower ends of the front portion are respectively provided with a first battery column and a second battery column with inwardly U-shaped openings. The top of the first battery column is rotatably connected to a square battery cover, and the bottom of the second battery column is fixed with a cover. A wire hole and a plurality of heat dissipation holes are provided on the backplate. The wire hole is located at the upper portion of the backplate and penetrates the backplate in the thickness direction. The cross-section shape is two intersecting circles.

[0009] A slide rail assembly is also provided on the back panel in the vertical direction outside the main body, and a corresponding slide rail is provided on the main body.

[0010] The slide rail assembly includes a first slide rail and a second slide rail. The first slide rail and the second slide rail are arranged opposite and parallel to each other on the surface of the back plate close to the main body. The straight-line distance between the first slide rail and the second slide rail is greater than 1 / 2 of the width of the back plate.

[0011] The cross-sections of the first slide rail and the second slide rail are L-shaped, and the corners of the slide rail combination are both located at the end away from the back plate. On the principle of ensuring simple process, the material consumption is saved to achieve the sliding connection function.

[0012] As an advantage, the slide rail assembly can also be designed to be horizontal.

[0013] A control module is set inside the main body, and the center of gravity of the control module is located on the side of the main body away from the back plate. There is more space inside the main body to place other mechanical structures of the robot.

[0014] Furthermore, the control module includes a sensor, an actuator and a controller.

[0015] The radii of the two intersecting circles in the cross-section of the wire hole are equal, and the distance between the centers of the two intersecting circles is greater than the radius and less than the diameter. It is practical for square lithium batteries, and the connecting wire connector of the lithium battery is square. Therefore, further, the length of the line connecting the intersection of the two intersecting circles is greater than the length of the connector cross-section.

[0016] The wire hole is located at the rear of the first battery column and avoids the position of the slide rail assembly. After the lithium battery connector passes through the wire hole, the two battery power cables are placed separately in the two intersecting circles of the wire hole. After the battery power cables are electrically connected to the power cables of the robot body, they are placed between the slide rail assemblies.

[0017] There are opening plates extending outwards on both sides of the upper part of the battery cover for opening the battery cover.

[0018] Preferably, a buckle may be provided at the lower end of the battery cover to better cooperate with the first battery bar, and textures may be provided on the top and bottom of the opening plate to increase friction and make it easier to open the battery cover.

[0019] The heat dissipation holes are rectangular, evenly distributed between the first battery column and the second battery column, and located between the first slide rail and the second slide rail. They can help the battery dissipate the heat generated when the battery is discharged. The rectangular design can increase the strength of the back panel in the width direction.

[0020] In addition, the closed bottom design of the second battery compartment can protect the battery from being contaminated by ground stains when the robot is operating in a harsh environment.

[0021] Beneficial Effects: To further optimize the performance and structural layout of traditional four-wheel, eight-wheel drive robots, the battery placement method was changed. Specifically, a battery connection device for a four-wheel, eight-wheel drive robot was developed. This device externally mounts the battery on the robot, rather than the traditional internal placement. This design allows for battery position adjustment without increasing the robot's overall height, ensuring the robot maintains a normal power supply and preventing changes in battery placement from affecting its operating efficiency and stability.

[0022] By placing the battery externally, valuable space within the robot's main body is freed up, allowing it to be more efficiently used to house the mechanical components necessary for its operation, including but not limited to the drive motor, transmission, and sophisticated steering system. Furthermore, the control module can be placed in a more spacious environment, improving heat dissipation and facilitating future maintenance and upgrades. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solution of this utility model is as follows:

[0031] See also Figure 1 A battery connection device for a four-wheel, eight-wheel drive robot. The robot includes an upper body and lower wheels including a back plate 4. The rear of the back plate 4 is slidably connected to the outer side wall in the length direction of the body. The upper and lower ends of the front are respectively provided with a first battery column 1 and a second battery column 3 with an inward-facing U-shaped opening. The top of the first battery column 1 is rotatably connected to a square battery cover 2, and the bottom of the second battery column 3 is fixed with a cover; a wire hole 7 and a plurality of heat dissipation holes 5 are provided on the back plate 4. The wire hole 7 is located at the upper part of the back plate 4 and passes through the back plate 4 in the thickness direction. The cross-sectional shape is two intersecting circles.

[0032] A slide rail assembly 6 is also provided on the back panel 4 in the vertical direction outside the main body, and a corresponding slide rail 9 is provided on the main body. The slide rail assembly 6 and the slide rail 9 cooperate to complete the detachable connection of the battery connection device. This sliding method is simple and efficient, saves space, and the position in the middle of the slide rail assembly 6 can also be used for better heat dissipation.

[0033] The slide rail assembly 6 includes a first slide rail 601 and a second slide rail 602. The first slide rail 601 and the second slide rail 602 are arranged opposite and parallel to each other on the surface of the back plate 4 close to the main body. The straight-line distance between the first slide rail 601 and the second slide rail 602 is greater than 1 / 2 of the width of the back plate 4.

[0034] The first slide rail 601 and the second slide rail 602 have an L-shaped cross section. Figure 4 The corners of the slide rail assembly 6 are all located at one end away from the back plate 4, and the bottom of the slide rail 9 is a closed design. On the principle of ensuring simple process, the material consumption is saved to achieve the sliding connection function.

[0035] Preferably, the slide rail assembly 6 can also be designed to be horizontal, and the cross section can be designed to be other shapes that are conducive to connection.

[0036] A control module is provided inside the main body, and the center of gravity of the control module is located on the side of the main body away from the back plate 4. There is more space inside the main body to place other mechanical structures of the robot.

[0037] Furthermore, the control module includes a sensor, an actuator and a controller.

[0038] The radii of the two intersecting circles in the cross section of the through hole 7 are equal, and the distance between the centers of the two intersecting circles is greater than the radius and less than the diameter. Figure 3 , it is practical to cooperate with square lithium batteries. The connecting wire connector of the lithium battery is square, so further, the length of the line connecting the intersection of the two intersecting circles is greater than the length of the connector section.

[0039] The wire hole 7 is located at the rear of the first battery column 1 and avoids the position of the slide rail assembly 6. After the lithium battery connector passes through the wire hole 7, the two battery power lines are placed separately in the two intersecting circles of the wire hole 7. The battery power lines are electrically connected to the power lines of the robot body and placed between the slide rail assembly 6.

[0040] Opening plates extend outward from both sides of the upper portion of the battery cover 2 for opening the battery cover 2 .

[0041] Preferably, a buckle can be provided at the lower end of the battery cover 2 to better cooperate with the first battery column 1 , and textures can be provided on the top and bottom of the opening plate to increase friction and make it easier to open the battery cover 2 .

[0042] Combine Figure 2 The specific location of the heat dissipation holes 5 is introduced. The heat dissipation holes 5 are rectangular and evenly distributed between the first battery column 1 and the second battery column 3. They are located between the first slide rail 601 and the second slide rail 602. When the battery is discharged, the heat dissipation holes can help the battery dissipate the heat generated. The rectangular design can increase the strength of the back plate 4 in the width direction.

[0043] In addition, the design of the bottom cover of the second battery column 3 can protect the battery from being contaminated by ground stains when the robot is operating in a poor environment, such as farmland or mines, where the ground is muddy or dusty.

[0044] Beneficial effect: The battery placement method of the traditional four-wheel eight-wheel drive robot is changed, and the battery is hung on the outside of the robot through the battery connection device of this new design. On the basis of not increasing the height of the robot, the normal power supply is guaranteed. In addition, there is more space inside the robot body with external battery to place the necessary mechanical structure and control module.

[0045] To further optimize the performance and structural layout of traditional four-wheel, eight-wheel drive robots, the battery placement was modified. Specifically, a battery connection device for the four-wheel, eight-wheel drive robot was developed. This device attaches the battery externally to the robot, rather than internally as is traditionally done. This design allows for battery position adjustment without increasing the robot's overall height, ensuring the robot maintains a normal power supply and preventing changes in battery placement from affecting its operating efficiency and stability.

[0046] By placing the battery externally, valuable space within the robot's main body is freed up, allowing it to be more efficiently used to house the mechanical components necessary for its operation, including but not limited to the drive motor, transmission, and sophisticated steering system. Furthermore, the control module can be placed in a more spacious environment, improving heat dissipation and facilitating future maintenance and upgrades.

[0047] In summary, the battery connection device designed in this utility model not only solves the traditional problem of battery placement, but also provides the possibility for optimizing the internal structure of the robot, so that the four-wheel eight-wheel drive robot has stronger functionality and higher operating efficiency while maintaining a compact size.
