Battery components and snow-clearing robots

[0001] Priority information

[0002] This application claims priority to three Chinese patent applications filed on September 7, 2023, with application numbers 202322450162.2, 202322449202.1, and 202322439021.0, the entire text of which is incorporated herein by reference. Technical Field

[0003] The present application relates to the field of robotics technology, and in particular to a battery assembly and a snow-clearing robot. Background Art

[0004] With the rapid development of robotics, everyday robots have become ubiquitous in our lives. Snowplow robots, a type of household robot, consist of a snowplow mechanism and a vehicle that tows the snowplow around the yard. The vehicle is typically wheeled or tracked. The snowplow mechanism includes a snowroller and a snowthrower. The snowroller gathers snow from the ground into a snowroller chamber, which is then thrown in a designated direction by the snowthrower.

[0005] In pursuit of low-carbon, environmentally friendly, energy-saving, and emission-reduction initiatives, traditional fuel-powered snowplows are gradually being phased out. The current trend in snowplows is primarily toward battery-powered electric structures. Currently, a common battery solution on the market involves removing the battery from the main snowplow and connecting it to the battery's charging port via a separate charging dock to charge the battery. Once the battery is installed in the main snowplow, a separate power cable connects the battery's discharge port to the snowplow to discharge the battery.

[0055] As shown in Figures 1 to 9, the present application provides a battery assembly, which includes a battery 1 and a battery compartment 2. The battery 1 can be quickly installed in or removed from the battery compartment 2. When the battery 1 is inserted into the battery compartment 2, power can be supplied to the outside (such as the snow-clearing robot host) through the battery compartment 2. When the battery 1 is low on power, the battery 1 can be removed from the battery compartment 2 and charged. After charging is complete, the battery 1 can be placed back into the battery compartment 2 for continuous power supply.

[0056] As shown in Figures 1 and 5, in this embodiment, the battery 1 includes a cell body 3, a top protective cover 4, and a bottom protective cover 5. The top protective cover 4 is arranged on the top of the cell body 3 and is detachably connected to the cell body 3. The top of the top protective cover 4 is provided with a plurality of first through holes 6 along a circumferential ring. First connecting bolts 7 are inserted into the first through holes 6. The top of the cell body 3 is provided with a plurality of first connecting holes (not shown). The plurality of first connecting holes are arranged in a one-to-one correspondence with the plurality of first through holes 6. The first connecting bolts 7 can pass through the first connecting holes 6 and be connected with nuts to fix the top protective cover 4 relative to the cell body 3. In this way, a detachable connection between the top protective cover 4 and the cell body 3 can be achieved. Like the top protective cover 4, the bottom protective cover 5 is also detachably connected to the cell body 3 in this way, which will not be described in detail here.

[0057] As shown in FIG5 , in this embodiment, a downwardly recessed first groove 23 is provided at the top of the top protective cover 4. The top protective cover 4 is also provided with a handle 24, which spans across both ends of the first groove 23. The first groove 23 makes it convenient for a person to grip the handle 24. The handle 24 can be used to pull or push the battery 1, making it convenient to remove or install it from the battery compartment 2.

[0058] In conjunction with Figures 3, 4, and 9, in this embodiment, a female connector 9 is provided at or adjacent to the top edge of the battery cell body 3. The bottom of the female connector 9 is exposed outside the battery cell body 3, and the female connector 9 serves as the charging and discharging interface of the battery cell body 3. The battery compartment 2 is generally cylindrical in shape and compatible with the battery 1, and the battery 1 can be inserted into the battery compartment 2. A male connector 8 compatible with the female connector 9 is provided within the battery compartment 2. When the battery 1 is installed in the battery compartment 2, the male connector 8 can be plugged into the female connector 9.

[0059] The battery 1 is generally in the shape of a rectangular parallelepiped. In other embodiments, the shape of the battery 1 may be changed.

[0060] In some embodiments, the positions of the female connector 9 and the male connector 8 can be interchanged, that is, the male connector 8 is arranged on the battery cell body 3 and the female connector 9 is arranged in the battery compartment 2 .

[0061] When the battery 1 is removed from the battery compartment 2, the battery 1 can be charged through the female connector 9. After the battery 1 is fully charged, it is placed back into the battery compartment 2, and the female connector 9 is plugged into the male connector 8. The female connector 9 then serves as a discharge interface for discharge through the battery compartment 2. It can be seen that the female connector 9 can serve as both a charging interface and a discharging interface, thereby integrating the charging and discharging interfaces of the battery 1. Users do not need to distinguish between the charging and discharging interfaces during use, making operation simple and convenient.

[0062] In addition, when the battery 1 is installed in the battery compartment 2, it is no longer necessary to connect it to the battery compartment 2 through an additional power cord. It can be connected directly by plugging the female socket 9 and the male plug connector 8. This reduces the circuit damage caused by the user during the installation and removal of the battery 1, extends the battery life, and realizes the rapid disassembly and assembly of the battery assembly.

[0063] It can be understood that in conventional battery solutions, the charging interface and the discharging interface of the battery are independent of each other and located in different positions, which increases the manufacturing cost of the battery and also increases the difficulty for users to install the battery. The battery assembly of the present application can better solve this problem, thereby reducing the manufacturing cost of the battery 1 and making the operation of the user installing the battery 1 simple and convenient.

[0064] In addition, the male connector 8 is arranged at the top position of the battery compartment 2, and the connecting socket 9 is arranged at the top position of the battery 1. After the male connector 8 and the connecting socket 9 are plugged in and matched, they are located at a higher vertical height. Snow water will not enter the male connector 8 and the connecting socket 9, thereby avoiding damage to the battery assembly, so that the battery assembly has a waterproof function.

[0065] In this embodiment, a female socket circuit board 32 is further provided between the top protective cover 4 and the female connection socket 9 . The female connection socket 9 is fixed below the female socket circuit board 32 and is electrically connected to the female socket circuit board 32 .

[0066] Specifically, the space between the side walls forming the first groove 23 and the side walls forming the top protective cover 4 forms a mounting cavity 41 , and the female socket circuit board 32 is disposed in the mounting cavity 41 and electrically connected to the battery cell body 3 .

[0067] A female seat protective cover 26 is provided on the outer periphery of the connecting female seat 9, which protects the connecting female seat 9 in the circumferential direction and prevents snow, water, sand and dust from entering the connecting female seat 9 and causing damage or failure of the connecting female seat 9.

[0068] As shown in Figure 9, in this embodiment, the female base protective cover 26 is an overall plate-shaped structure. The female base protective cover 26 is provided with a female base fixing cavity 261 along the vertical direction. The female base fixing cavity 261 passes through the female base protective cover 26. The connecting female base 9 can be inserted into the female base fixing cavity. The bottom surface of the connecting female base 9 is flush with the lower side of the inner surface of the female base fixing cavity to facilitate docking with the male connector 8 in the battery compartment 2. In some embodiments, the bottom surface of the connecting female base 9 can also be made slightly higher than the lower side of the inner surface of the female base fixing cavity 261, so that the bottom of the connecting female base 9 is not exposed to the outside, which can provide a protective effect on the bottom of the connecting female base 9.

[0069] Thus, the battery assembly of this embodiment includes a battery 1 and a battery compartment 2. The battery 1 includes a battery cell body 3 and a female connector 9. The female connector 9 is located at the top edge of the battery cell body 3 or adjacent to the battery cell body 3. The bottom of the female connector 9 is exposed outside the battery cell body 3. The outer periphery of the female connector 9 is also covered with a female connector protective cover 26. The female connector protective cover 26 is provided with a female connector fixing cavity 261. The female connector 9 can be inserted into the female connector fixing cavity 261. The bottom surface of the female connector 9 is flush with the lower side of the inner surface of the female connector fixing cavity 261 or the bottom surface of the female connector 9 is slightly higher than the lower side of the inner surface of the female connector fixing cavity 261. The battery 1 can be inserted into the battery compartment 2. The battery compartment 2 is provided with a male connector 8 that is compatible with the female connector 9. When the battery 1 is installed in the battery compartment 2, the male connector 8 can be plugged into the female connector 9. The socket protection cover 26 protects the connection socket 9, preventing snow, water, sand and dust from entering the connection socket 9 and causing damage or failure of the connection socket 9, so that the battery assembly has an interface protection function.

[0070] In this embodiment, the top protective cover 4 is disposed on the top of the cell body 3 and is detachably connected to the cell body 3. The top protective cover 4 covers the top of the female connector 9. In this way, the top of the female connector 9 is enclosed within the top protective cover 4, thereby providing protection for the top of the female connector 9.

[0071] Specifically, the top protective cover 4 covers the top of the connecting female seat 9 and the female seat protective cover 26 at the same time, that is, the top of the connecting female seat 9 and the female seat protective cover 26 are both covered in the top protective cover 4, so that the top protective cover 4 can protect the top of the connecting female seat 9 and the female seat protective cover 26.

[0072] In this embodiment, a plurality of connecting ears 262 are provided on the edge of the female seat protective cover 26 along the circumference of the female seat protective cover 26 , and the female seat protective cover 26 is detachably connected to the top protective cover 4 through the connecting ears 262 .

[0073] As shown in Figure 5, in this embodiment, one side of the female socket protective cover 26 is exposed on the side of the battery body 3, and remains flush with the side wall of the top protective cover 4 on that side. When encountering rain or snow, the water flows downward along the side wall of the top protective cover 4 and the side wall of the female socket protective cover 26, and will not enter the connection between the female socket 9 and the male plug connector 8, thereby preventing the female socket 9 and the male plug connector 8 from being damaged or failing due to water.

[0074] A slide groove 27 is provided in the vertical direction on one side of the battery cell body 3 close to the female socket protective cover 26, and the female socket protective cover 26 is located at the top of the slide groove 27. The battery cell body 3 can slide downward in the vertical direction relative to the male plug connector 8 through the slide groove 27, so that the male plug connector 8 can be quickly docked with the connecting female socket 9.

[0075] In combination with Figures 1, 2 and 6, in this embodiment, the battery compartment 2 includes a base 10 and a front baffle 11, a rear baffle 12, a left baffle 13 and a right baffle 14 perpendicular to the base 10. The front baffle 11, the rear baffle 12, the left baffle 13 and the right baffle 14 together form a accommodating cavity 33 for accommodating the battery 1, and the shape of the accommodating cavity 33 is adapted to the battery 1.

[0076] Furthermore, in FIG6 , the base 10 includes a bottom plate 101 and a first support wall 102 and a second support wall 103 arranged at the bottom of the bottom plate 101 . The first support wall 102 and the second support wall 103 are respectively located at the front and rear sides of the bottom plate 101 and are perpendicular to the bottom plate 101 .

[0077] In this embodiment, the rear baffle 12, the left baffle 13 and the right baffle 14 are integrally formed to form a U-shaped structure. The front baffle 11 and the left baffle 13, as well as the front baffle 11 and the right baffle 14, are both detachably connected.

[0078] Specifically, a second through hole 34 is provided on both sides of the front baffle 11, and a second connecting bolt 15 is passed through the second through hole 34. A connecting plate 16 is provided on the edges of the left baffle 13 and the right baffle 14 close to the front baffle 11. The connecting plate 16 is parallel to the front baffle 11, and the connecting plate 16 extends in a direction away from the left baffle 13 or the right baffle 14. The connecting plate 16 is provided with a second connecting hole 17 corresponding to the second through hole 34. The second connecting bolt 15 can pass through the second connecting hole 17 and be connected with a nut to relatively fix the front baffle 11 and the left baffle 13, and the front baffle 11 and the right baffle 14.

[0079] In this embodiment, the parts of the rear baffle 12, the left baffle 13 and the right baffle 14 near the top are slightly tilted outward to form an expansion portion 22. Multiple expansion portions 22 are enclosed to form a conical structure with a wide top and a narrow bottom, which is more conducive to inserting the battery 1 into the battery compartment 2 from the top of the battery compartment 2.
