Description

Technical Field

[0001] The present invention relates to the technical field of unmanned vehicles, and in particular to a battery installation mechanism and a plant protection unmanned vehicle. Background Art

[0002] With the continuous development of science and technology, unmanned vehicles have been widely used in all aspects of people's daily life. The power batteries on unmanned vehicles are all detachable, so that they can be removed for charging or installed to power the entire vehicle. However, during the disassembly and assembly process of current power batteries, due to the large friction resistance, people need to apply a large force to successfully disassemble and assemble them, which is inconvenient and inefficient.

[0003] In view of this, it is particularly important to design and manufacture a battery installation mechanism and a plant protection unmanned vehicle that are easy to disassemble and assemble, especially in the production of unmanned vehicles. Summary of the invention

[0004] The object of the present invention is to provide a battery installation mechanism with a simple structure, which can reduce the friction resistance generated during the battery disassembly and assembly process, thereby reducing manual force, facilitating disassembly and assembly, and increasing disassembly and assembly efficiency.

[0005] Another object of the present invention is to provide a plant protection unmanned vehicle, in which the battery installation mechanism has a simple structure and can reduce the friction resistance generated during the battery disassembly and assembly process, thereby reducing manual force, facilitating disassembly and assembly, and increasing disassembly and assembly efficiency.

[0006] The present invention is achieved by adopting the following technical solutions.

[0007] A battery mounting mechanism comprises a mounting frame, a power battery and a guide assembly; a receiving cavity is arranged in the mounting frame; the power battery is accommodated in the receiving cavity, and a slide groove is provided in the power battery; the guide assembly comprises a limit plate and a guide wheel, the limit plate is fixedly connected to the mounting frame and is arranged in the receiving cavity, the guide wheel is mounted on the limit plate and can rotate relative to the limit plate, and the guide wheel is used for rolling cooperation with the slide groove so that the power battery can be inserted into the receiving cavity or pulled out from the receiving cavity.

[0008] Furthermore, the power battery is inserted into the accommodating cavity along the extension direction of the slide slot, and the extension direction of the slide slot is arranged at a first preset angle with the horizontal plane. The inclined power battery can utilize the gravity of the power battery to make the power battery slide downward, thereby reducing manual force.

[0009] Furthermore, the first preset angle ranges from 45 degrees to 75 degrees. An appropriate first preset angle can ensure that the power battery can slide smoothly into the accommodating cavity along the extension direction of the slide slot, reduce manual force, and improve disassembly and assembly efficiency.

[0010] Further, the chute is provided with a first side wall, the guide wheel comprises a first guide wheel, the diameter of the first guide wheel is smaller than the width of the chute, and the first guide wheel is in rolling cooperation with the first side wall. The first guide wheel can roll on the first side wall and is spaced apart from the second side wall, and the second side wall will not interfere with the rotation of the first guide wheel.

[0011] Furthermore, the chute is further provided with a second side wall, the second side wall is parallel to the first side wall and is provided below the first side wall, the guide wheel further includes a second guide wheel, the diameter of the second guide wheel is smaller than the width of the chute, and the second guide wheel and the second side wall are in rolling cooperation.

[0012] Furthermore, the connecting line of the axis of the first guide wheel and the axis of the second guide wheel is arranged at a second preset angle with the extension direction of the slide slot. The first guide wheel abuts against the first side wall of the slide slot, and the second guide wheel abuts against the second side wall of the slide slot to limit the position and sliding direction of the power battery.

[0013] Furthermore, the second preset angle ranges from 2 degrees to 8 degrees. The second preset angle with an appropriate value can ensure that the first guide wheel and the second guide wheel simultaneously limit the slide slot of the power battery to prevent the power battery from moving.

The first guide wheel and the second guide wheel are relatively arranged at two ends of the guide plate, and both protrude from the edge of the guide plate, so that the first guide wheel and the second guide wheel will not be interfered by the guide plate when they cooperate with the slide groove of the power battery.

[0015] Furthermore, the limiting plate is in a bent shape, and includes an integrally formed first bent portion and a second bent portion, the first bent portion is fixedly connected to the mounting frame, the second bent portion is rotatably connected to the guide wheel, and the extension direction of the second bent portion is the same as the extension direction of the slide slot, so that the power battery can cooperate with the guide wheel along the extension direction of the slide slot.

[0016] Furthermore, there are two guide assemblies and two slide grooves, which are arranged on both sides of the power battery. Each guide assembly cooperates with a slide groove to limit and guide the two sides of the power battery at the same time, thereby improving the sliding stability of the power battery and facilitating the insertion or extraction of the power battery into the accommodating cavity.

[0040] First embodiment

[0041] Please refer to Figure 1, an embodiment of the present invention provides a battery installation mechanism 100 for realizing the disassembly and installation of a battery. It has a simple structure, can reduce the friction resistance generated during the disassembly and installation of the battery, so as to reduce the manual force, facilitate the disassembly and installation, and have high disassembly and installation efficiency.

The guide assembly 130 is installed on the mounting frame 110 and is provided in the receiving cavity 111. The guide assembly 130 can guide and limit the power battery 120 so that the power battery 120 can be smoothly inserted into the receiving cavity 111 or pulled out from the receiving cavity 111, thereby reducing the friction resistance generated by the power battery 120 during the insertion and removal process, facilitating disassembly and assembly, and improving disassembly and assembly efficiency. The power socket 140 is fixedly installed on the mounting frame 110. The power battery 120 can be plugged into the power socket 140 during the installation process to achieve electrical connection between the power battery 120 and the power socket 140, so that the power battery 120 can supply power to the unmanned vehicle. The power battery 120 can also be separated from the power socket 140 during the disassembly process to disconnect the circuit formed by the power battery 120 and the power socket 140, thereby cutting off the power to the unmanned vehicle, which is stable and reliable.

Since the triangle has the strongest stability and has the characteristics of being stable, firm and pressure-resistant, the structure of the entire mounting frame 110 is firm and reliable, and has strong stability.

[0044] The first bracket 112 includes a first crossbar 1121, a second crossbar 1122, a positioning rod 1123 and two U-shaped rods 1124. The first crossbar 1121 and the second crossbar 1122 are both fixedly connected between the two U-shaped rods 1124. The first crossbar 1121 and the second crossbar 1122 are relatively arranged at two free ends of the U-shaped rods 1124 to fix the relative position between the two U-shaped rods 1124. The U-shaped rods 1124 are hung on the front end of the vehicle body 200, the first crossbar 1121 is fixedly connected to the second bracket 113, the second crossbar 1122 is fixedly connected to the bottom surface of the vehicle body 200, the U-shaped rod 1124 is abutted against the front end of the vehicle body 200, and the vehicle body 200 can limit the U-shaped rod 1124. The positioning rod 1123 is fixedly connected between the two U-shaped rods 1124, and is arranged between the first cross bar 1121 and the second cross bar 1122, and is located on the top surface of the vehicle body 200. A receiving cavity 111 for accommodating the power battery 120 is formed between the positioning rod 1123 and the first cross bar 1121. The power socket 140 is fixedly connected to the positioning rod 1123. The power socket 140 is used to be plugged into the power battery 120 to achieve electrical connection between the power battery 120 and the power socket 140, so that the power battery 120 can supply power to the unmanned vehicle.

[0045] It should be noted that the U-shaped rod 1124 includes a first connecting rod 1125, a second connecting rod 1126 and a third connecting rod 1127. The first connecting rod 1125 is fixedly connected to the third connecting rod 1127 through the second connecting rod 1126, the first connecting rod 1125 is fixedly connected to the first crossbar 1121, and is fixedly connected to the positioning rod 1123, the third connecting rod 1127 is fixedly connected to the second crossbar 1122, and one first connecting rod 1125, the positioning rod 1123, another first connecting rod 1125 and the first crossbar 1121 are combined to form a receiving cavity 111. The first connecting rod 1125, the second connecting rod 1126 and the third connecting rod 1127 are combined to form a U shape, and the first connecting rod 1125 and the third connecting rod 1127 are arranged in parallel and spaced apart, and are both arranged perpendicular to the second connecting rod 1126.

Specifically, the length of the first connecting rod 1125 is greater than the length of the third connecting rod 1127. When the U-shaped rod 1124 is hung on the front end of the vehicle body 200, the first connecting rod 1125 is located above the top surface of the vehicle body 200 and is inclined relative to the top surface of the vehicle body 200. The second connecting rod 1126 is located on the side of the vehicle body 200, and the third connecting rod 1127 is located below the bottom surface of the vehicle body 200.

[0046] In this embodiment, since there are two U-shaped rods 1124, there are two first connecting rods 1125. A first connecting rod 1125, a positioning rod 1123, another first connecting rod 1125 and a first cross bar 1121 are combined to form an opening, which extends toward the direction close to the vehicle body 200 to form a receiving cavity 111 to accommodate the power battery 120. Specifically, the top surface of the vehicle body 200 is located on a horizontal plane, the horizontal plane where the positioning rod 1123 is located is lower than the horizontal plane where the first cross bar 1121 is located, the first cross bar 1121 is higher than the positioning rod 1123, the two first connecting rods 1125 are both arranged obliquely to the horizontal plane, the plane where the opening formed by the combination of a first connecting rod 1125, the positioning rod 1123, another first connecting rod 1125 and the first cross bar 1121 is located is inclined to the horizontal plane, and the receiving cavity 111 is also inclined to the horizontal plane.

[0047] When the power battery 120 is inserted obliquely into the accommodating cavity 111, the power battery 120 first passes through an opening formed by a first connecting rod 1125, a positioning rod 1123, another first connecting rod 1125 and a first cross bar 1121, and then the power battery 120 continues to move downward until it abuts against the top surface of the vehicle body 200. At this time, the power battery 120 is arranged obliquely to the horizontal plane and also to the top surface of the vehicle body 200, and one side of the power battery 120 leans on the positioning rod 1123.

[0048] The second bracket 113 includes a first longitudinal rod 1131, a second longitudinal rod 1132, a third crossbar 1133 and two support frames 1134. One end of the first longitudinal rod 1131 is fixedly connected to one end of the second longitudinal rod 1132 through the first crossbar 1121, and the other end of the first longitudinal rod 1131 is fixedly connected to the other end of the second longitudinal rod 1132 through the third crossbar 1133, and the third crossbar 1133 is clamped with the vehicle body 200. The first longitudinal rod 1131, the third crossbar 1133 and the second longitudinal rod 1132 are combined to form a U shape, and the first longitudinal rod 1131 is arranged parallel to the second longitudinal rod 1132 and spaced apart, and both are arranged perpendicular to the third crossbar 1133. In this embodiment, the first longitudinal rod 1131, the third crossbar 1133 and the second longitudinal rod 1132 are integrally formed to improve the connection strength. Specifically, one support frame 1134 is fixedly connected between the first longitudinal rod 1131 and the vehicle body 200 , and another support frame 1134 is fixedly connected between the second longitudinal rod 1132 and the vehicle body 200 . The two support frames 1134 work together to support the second bracket 113 to fix the relative position between the second bracket 113 and the vehicle body 200 .

[0049] It should be noted that the support frame 1134 includes a first bearing rod 1135, a second bearing rod 1136 and a third bearing rod 1137. The first bearing rod 1135 is fixedly connected to the third bearing rod 1137 through the second bearing rod 1136. The first bearing rod 1135 and the third bearing rod 1137 are both fixedly connected to the first longitudinal rod 1131 or the second longitudinal rod 1132. The second bearing rod 1136 is arranged to fit the top surface of the vehicle body 200 and is fixedly connected to the vehicle body 200 to support and fix the first longitudinal rod 1131 or the second longitudinal rod 1132 to prevent the first longitudinal rod 1131 or the second longitudinal rod 1132 from being deformed or bent.

In this embodiment, the top bar 1141, the bottom bar 1142 and the two side bars 1143 are integrally formed to improve the connection strength.

[0051] It is worth noting that the connection between the first connecting rod 1125 and the second connecting rod 1126 is an arc transition, the connection between the second connecting rod 1126 and the third connecting rod 1127 is an arc transition, the connection between the third connecting rod 1127 and the second crossbar 1122 is an arc transition; the connection between the first longitudinal rod 1131 and the third crossbar 1133 is an arc transition, the connection between the third crossbar 1133 and the second longitudinal rod 1132 is an arc transition; the connection between the top rod 1141 and the side rod 1143 is an arc transition, and the connection between the bottom rod 1142 and the side rod 1143 is an arc transition. This is to enhance the force transmission effect, prevent cutting of staff, and improve the aesthetics.

[0052] In this embodiment, a clamping member (not shown) is provided on the vehicle body 200, and the clamping member has a clamping slot (not shown), and the third cross bar 1133 is clamped in the clamping slot to fix the relative position of the third cross bar 1133 and the vehicle body 200, and to facilitate disassembly and assembly. Specifically, the clamping slot is provided on a side of the clamping member close to the first bracket 112, and when the third cross bar 1133 is clamped in the clamping slot, the clamping member can apply a resisting force to the third cross bar 1133, and the direction of the resisting force is the direction close to the first bracket 112 on the horizontal plane, that is, the direction toward the front end of the vehicle body 200, so as to prevent the third cross bar 1133 from sliding toward the rear end of the vehicle body 200, thereby fixing the position of the entire second bracket 113.

[0053] In this embodiment, the first bracket 112, the second bracket 113 and the third bracket 114 are all processed from a hollow circular tubular rod structure, which has low processing cost and is easy to assemble and connect. However, this is not limited to this. In other embodiments, the first bracket 112, the second bracket 113 and the third bracket 114 can also be processed from a solid circular tubular rod structure.

[0054] Please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 ( Figure 8The dotted line in the figure is the length direction of the power battery 120), and the guide assembly 130 includes a limit plate 131, a guide wheel 132 and a guide plate 133. The limit plate 131 is fixedly connected to the first connecting rod 1125 of the mounting frame 110, and is disposed in the accommodating cavity 111. The guide wheel 132 is mounted on the limit plate 131 and can rotate relative to the limit plate 131. The power battery 120 is provided with a slide groove 121, and the guide wheel 132 is used to roll with the slide groove 121 so that the power battery 120 can be inserted into the accommodating cavity 111 or pulled out from the accommodating cavity 111. In the process of inserting the power battery 120 into the accommodating cavity 111 or pulling it out from the accommodating cavity 111, the guide wheel 132 can roll relative to the slide groove 121, and there is rolling friction between the guide wheel 132 and the slide groove 121, so that the friction resistance generated is small, thereby reducing manual force and facilitating disassembly and assembly. Specifically, the guide plate 133 is connected between the limit plate 131 and the guide wheel 132. One side of the guide plate 133 is fixedly connected to the limit plate 131, and the other side is rotatably connected to the guide wheel 132. The axial direction of the guide wheel 132 is perpendicular to the plane where the guide plate 133 is located. The guide wheel 132 can rotate relative to the guide plate 133, and the guide plate 133 can improve the stability of the guide wheel 132 during rotation.

[0055] It is worth noting that the power battery 120 is inserted into the accommodating cavity 111 along the extension direction of the chute 121, and the extension direction of the chute 121 is set at a first preset angle with the horizontal plane, that is, the extension direction of the chute 121 is set at an angle to the horizontal plane. In this embodiment, the extension direction of the chute 121 is the length direction of the power battery 120, and the power battery 120 can be inserted into the accommodating cavity 111 or pulled out from the accommodating cavity 111 along its length direction, and the length direction of the power battery 120 is also set at a first preset angle with the horizontal plane. Specifically, the mounting frame 110 is fixedly installed on the top surface of the vehicle body 200, and the top surface of the vehicle body 200 is a horizontal plane. The power battery 120 is set in the accommodating cavity 111 and is inclined relative to the top surface of the vehicle body 200. The power battery 120 can be inserted into the accommodating cavity 111 or pulled out from the accommodating cavity 111 at an angle. For ease of understanding, the first preset angle is represented as a1.

[0056] It should be noted that the first preset angle ranges from 45 degrees to 75 degrees. In this embodiment, the first preset angle is 67 degrees, but it is not limited thereto. In other embodiments, the first preset angle may be 45 degrees or 75 degrees. An appropriate first preset angle can ensure that the power battery 120 slides smoothly into the accommodating cavity 111 along the extension direction of the slide slot 121, thereby reducing manual force and improving disassembly and assembly efficiency.

[0057] The chute 121 is provided with a first side wall 122 and a second side wall 123 opposite to each other. The first side wall 122 and the second side wall 123 are arranged in parallel and spaced apart. Since the extending direction of the chute 121 is arranged obliquely to the horizontal plane, the first side wall 122 and the second side wall 123 are both arranged obliquely to the horizontal plane. Specifically, the first side wall 122 is arranged above the second side wall 123, and the second side wall 123 is arranged below the first side wall 122, that is, the first side wall 122 is arranged on the side of the second side wall 123 away from the vehicle body 200.

[0058] The guide wheel 132 includes a first guide wheel 1321 and a second guide wheel 1322. The diameter of the first guide wheel 1321 is the same as that of the second guide wheel 1322, and both are smaller than the width of the slide groove 121, that is, smaller than the distance between the first side wall 122 and the second side wall 123, so that the first guide wheel 1321 and the second guide wheel 1322 can roll in the slide groove 121. Specifically, the first guide wheel 1321 is in rolling cooperation with the first side wall 122, the first guide wheel 1321 can roll on the first side wall 122, and is spaced apart from the second side wall 123, and the second side wall 123 will not interfere with the rotation of the first guide wheel 1321; the second guide wheel 1322 is in rolling cooperation with the second side wall 123, the second guide wheel 1322 can roll on the second side wall 123, and is spaced apart from the first side wall 122, and the first side wall 122 will not interfere with the rotation of the second guide wheel 1322.

[0059] It should be noted that the first guide wheel 1321 is in rolling cooperation with the first side wall 122, the first side wall 122 is against the first guide wheel 1321, and the first guide wheel 1321 can support and limit the first side wall 122 to prevent the first side wall 122 from rotating. The second guide wheel 1322 is in rolling cooperation with the second side wall 123, the second side wall 123 is against the second guide wheel 1322, and the second guide wheel 1322 can support and limit the second side wall 123 to prevent the second side wall 123 from rotating. The first guide wheel 1321 and the second guide wheel 1322 work together to limit and guide the slide 121, and finally fix the position of the slide 121, thereby fixing the position of the power battery 120 and preventing the power battery 120 from moving.

[0060] Further, one side of the guide plate 133 is fixedly connected to the limit plate 131, and the other side is rotatably connected to the first guide wheel 1321 and the second guide wheel 1322 respectively, and the first guide wheel 1321 and the second guide wheel 1322 can rotate relative to the guide plate 133. The first guide wheel 1321 and the second guide wheel 1322 are relatively arranged at both ends of the guide plate 133, and both protrude from the edge of the guide plate 133, so that the first guide wheel 1321 and the second guide wheel 1322 will not be interfered by the guide plate 133 when they cooperate with the slide groove 121 of the power battery 120.

[0061] During the process of inserting the power battery 120 into the accommodating cavity 111, the power battery 120 is first manually tilted so that the extension direction of the slide groove 121 is set at a first preset angle with the horizontal plane, and then the power battery 120 is extended into the accommodating cavity 111. At this time, the slide groove 121 of the power battery 120 is set outside the first guide wheel 1321, and the first side wall 122 abuts against the first guide wheel 1321. Then, the power battery 120 slides downward under the action of gravity and continues to extend into the accommodating cavity 111. At this time, the first guide wheel 1321 rolls relative to the first side wall 122, and the second guide wheel 1322 is suspended, with small friction resistance; then the slide groove 121 is set outside the second guide wheel 1322, and the second side wall 123 abuts against the second guide wheel 1322. The first guide wheel 1321 and the second guide wheel 1322 are The first guide wheel 1321 and the second guide wheel 1322 work together to limit the sliding direction of the power battery 120; then the power battery 120 continues to slide downward under the action of gravity and extends into the accommodating cavity 111. At this time, the first guide wheel 1321 rolls relative to the first side wall 122, and the second guide wheel 1322 rolls relative to the second side wall 123, and the friction resistance is small; finally, the power battery 120 slides to the limit position, the power battery 120 abuts against the top surface of the vehicle body 200, and the vehicle body 200 limits the bottom surface of the power battery 120, so that the power battery 120 cannot continue to move downward. At this time, the first guide wheel 1321 limits one side of the power battery 120, and the second guide wheel 1322 limits the other side of the power battery 120 to prevent the power battery 120 from moving, and the installation is completed.

[0062] It should be noted that, during the process of inserting the power battery 120 into the accommodating cavity 111, if the power battery 120 has been matched with the first guide wheel 1321 but has not yet been matched with the second guide wheel 1322, at this time, since the power battery 120 is tilted, the first side wall 122 abuts against the first guide wheel 1321, so the power battery 120 has a tendency to rotate downward with the first guide wheel 1321 as the center. At this time, manual force is required to prevent the power battery 120 from rotating downward, and combined with the gravity of the power battery 120, The power battery 120 slides downward along the extension direction of the slide groove 121; if the power battery 120 cooperates with the first guide wheel 1321 and the second guide wheel 1322 at the same time, the second guide wheel 1322 abuts against the second side wall 123, and the second guide wheel 1322 applies a supporting force to the second side wall 123 to prevent the power battery 120 from rotating downward. In this process, the gravity of the power battery 120 itself can drive the power battery 120 to slide downward along the extension direction of the slide groove 121, thereby reducing the manual force application process and reducing manual force.

[0063] Further, when the power battery 120 is accommodated in the accommodation cavity 111, a force analysis is performed on the entire power battery 120. The first guide wheel 1321 abuts against the first side wall 122, the second guide wheel 1322 abuts against the second side wall 123, and the vehicle body 200 abuts against the bottom surface of the power battery 120. For ease of understanding, the gravity of the power battery 120 is represented as Fweight, the abutting force of the first guide wheel 1321 on the first side wall 122 is represented as F1, and the abutting force of the second guide wheel 1322 on the first side wall 123 is represented as F2. The supporting force of the second guide wheels 1322 on the second side wall 123 is represented as F2, and the supporting force of the vehicle body 200 on the bottom surface of the power battery 120 is represented as Fresistance. The gravity Fweight of the power battery 120 is balanced by the supporting force Fresistance of the vehicle body 200 on the bottom surface of the power battery 120. The supporting force F1 of the first guide wheel 1321 on the first side wall 122 is balanced by the supporting force F2 of the second guide wheel 1322 on the second side wall 123, so as to limit the position of the power battery 120.

[0064] In the process of pulling out the power battery 120 from the accommodating cavity 111, the power battery 120 is first manually pulled outward along the extension direction of the slide groove 121, so that the power battery 120 is separated from the top surface of the vehicle body 200. At this time, the slide groove 121 is arranged outside the first guide wheel 1321 and the second guide wheel 1322. The first guide wheel 1321 and the second guide wheel 1322 work together to limit the sliding direction of the power battery 120. The first guide wheel 1321 rolls relative to the first side wall 122, and the second guide wheel 1322 rolls relative to the second side wall 123, and the friction resistance is small; then the second guide wheel 1322 escapes from the slide groove 121, and the first guide wheel 1321 continues to roll relative to the first side wall 122, and the second guide wheel 1322 is suspended, and the friction resistance is small; finally, the first guide wheel 1321 escapes from the slide groove 121, and the entire power battery 120 is completely escaped from the accommodating cavity 111, and the disassembly is completed.

[0065] It should be noted that, during the process of pulling out the power battery 120 from the accommodating cavity 111, if the power battery 120 cooperates with the first guide wheel 1321 and the second guide wheel 1322 at the same time, the second guide wheel 1322 abuts against the second side wall 123, and the second guide wheel 1322 applies a holding force to the second side wall 123 to prevent the power battery 120 from rotating downward. In this process, only a manual force is required to be applied to the power battery 120 to pull it outward along the extension direction of the slide groove 121, and no additional force is required to prevent the power battery 120 from rotating downward. Rotate downward to reduce the manual force process and reduce manual force; if the power battery 120 only cooperates with the first guide wheel 1321 and is disengaged from the second guide wheel 1322, at this time, due to the inclined setting of the power battery 120, the first side wall 122 is against the first guide wheel 1321, so the power battery 120 has a tendency to rotate downward with the first guide wheel 1321 as the center. At this time, it is necessary to manually apply additional force in the process of pulling the power battery 120 outward along the extension direction of the slide slot 121 to prevent the power battery 120 from rotating downward.

[0066] It is worth noting that the power battery 120 is inserted into the accommodating cavity 111 along the extension direction of the chute 121, the first guide wheel 1321 abuts against the first side wall 122 of the chute 121, the second side wall 123 abuts against the second side wall 123 of the chute 121, and the line connecting the axis of the first guide wheel 1321 and the axis of the second guide wheel 1322 is arranged at a second preset angle with the extension direction of the chute 121, that is, the line connecting the axis of the first guide wheel 1321 and the axis of the second guide wheel 1322 is inclined to the extension direction of the chute 121, and the line connecting the axis of the first guide wheel 1321 and the axis of the second guide wheel 1322 is inclined to both the first side wall 122 and the second side wall 123. For ease of understanding, the second preset angle is represented as a2.

[0067] It should be noted that the second preset angle ranges from 2 degrees to 8 degrees. In this embodiment, the second preset angle is 4 degrees, but it is not limited thereto. In other embodiments, the second preset angle may be 2 degrees or 8 degrees. An appropriate second preset angle can ensure that the first guide wheel 1321 and the second guide wheel 1322 simultaneously limit the chute 121 of the power battery 120 to prevent the power battery 120 from moving.

[0068] In the present embodiment, the number of the first guide wheel 1321 and the number of the second guide wheel 1322 are both one, but this is not limited to this. In other embodiments, the number of the first guide wheels 1321 can be two or three, and the number of the second guide wheels 1322 can also be two or three. There is no specific limitation on the number of the first guide wheels 1321 and the second guide wheels 1322.

[0069] In this embodiment, there are two guide components 130 and two slide grooves 121. The two slide grooves 121 are relatively arranged on both sides of the power battery 120. Each guide component 130 cooperates with a slide groove 121 to simultaneously limit and guide the two sides of the power battery 120, thereby improving the sliding stability of the power battery 120 and facilitating the insertion of the power battery 120 into the accommodating cavity 111 or the removal of the power battery 120 from the accommodating cavity 111.

[0070] It is worth noting that the power battery 120 is provided with a plug-in 124, which is plugged into the power socket 140 to achieve electrical connection between the power battery 120 and the power socket 140, so that the power battery 120 can supply power to the unmanned vehicle. In this embodiment, a buckle (not shown) is provided on the plug-in 124, and a clamping hole (not shown) is provided on the power socket 140, and the buckle is clamped with the clamping hole to further fix the position of the power battery 120 and prevent the power battery 120 from escaping upward from the accommodating cavity 111.

[0071] Please refer to Fig. 9 It should be noted that the limit plate 131 is in a bent shape, and the limit plate 131 includes an integrally formed first bent portion 1311 and a second bent portion 1312 to improve the connection strength. The first bent portion 1311 is fixedly connected to the first connecting rod 1125 of the mounting frame 110, and the second bent portion 1312 is rotatably connected to the guide wheel 132 through the guide plate 133. The second bent portion 1312 is used to be fixedly connected to the vehicle body 200. The extension direction of the second bent portion 1312 is the same as the extension direction of the slide slot 121, so that the power battery 120 can cooperate with the guide wheel 132 along the extension direction of the slide slot 121.

[0072] The battery mounting mechanism 100 provided in the embodiment of the present invention comprises a mounting frame 110 provided with a receiving cavity 111, a power battery 120 received in the receiving cavity 111, a slide groove 121 provided in the power battery 120, a guide assembly 130 comprising a limit plate 131 and a guide wheel 132, the limit plate 131 being fixedly connected to the mounting frame 110 and being provided in the receiving cavity 111, the guide wheel 132 being installed on the limit plate 131 and being rotatable relative to the limit plate 131, the guide wheel 132 being used for rolling cooperation with the slide groove 121 so that the power battery 120 can be inserted into or pulled out of the receiving cavity 111. Compared with the prior art, the battery installation mechanism 100 provided by the present invention adopts a power battery 120 arranged in the accommodating cavity 111 and a guide wheel 132 that rolls with the slide groove 121, so it can reduce the friction resistance generated during the disassembly and assembly of the power battery 120, thereby reducing manual force, facilitating disassembly and assembly, and improving disassembly and assembly efficiency.
