[0002] At present, with the advancement of artificial intelligence electronic mechanical technology, more and more mobile robots have been used in various processing or service industries. When these robot equipment are in use, corresponding energy storage mechanisms will be installed inside them. When such robots are used for heavy load transportation, they lack external battery mechanisms, so their endurance is short and they are difficult to meet high-intensity production needs. After the robot is operated with an external battery, dust will be adsorbed on the surface of the external battery during transportation, affecting the heat dissipation performance of the battery. Summary of the invention

[0004] Furthermore, a snap-in groove corresponding to the L-shaped pin rod is formed on the lower wall of the main body, and the top of the L-shaped pin rod includes an elastic portion extending into the snap-in groove, thereby facilitating the pre-positioning of the L-shaped pin rod and improving the accuracy of docking between the main body and the mobile power block.

[0005] Furthermore, a ring body corresponding to the torsion bar is fixedly mounted on the right wall of the inner cavity of the plug-in slot, so that when the mobile power block drives the torsion bar to be plugged into the interior of the plug-in slot, the ring body can be used to block and prevent the mobile power block from falling out.

[0006] Furthermore, a guide groove corresponding to the guide sleeve is formed at the right end of the L-shaped pin rod, and the inner wall of the guide sleeve includes a strip portion extending into the guide groove, thereby facilitating the later removal of the mobile power block by utilizing the clamping mechanism of the two.

[0007] Furthermore, an annular groove is provided on the periphery of the guide sleeve, and the inner wall of the adjustment ring includes a protruding portion extending into the annular groove, so that the guide sleeve can drive the adjustment ring to move axially accordingly when rotating, so as to adjust the locking mechanism of the mobile power block.

[0008] Furthermore, it also includes a heat dissipation mechanism, which is movably connected to the right wall of the mobile power block, and the heat dissipation mechanism includes a heat sink, and a hollow bar is slidably connected to the periphery of the heat sink, and conical grooves are evenly opened on the inner wall of the hollow bar close to the heat sink, and a gear fan is rotatably connected to the upper wall of the inner cavity of the hollow bar, and an abutment spring is fixedly connected between the hollow bar and the side wall of the mobile power block, and an elastic magnetic block is slidably connected to the right inner wall of the mobile power block, and a winding bundle extending to the abutment spring is buried on the side of the inner wall of the mobile power block close to the elastic magnetic block.

[0009] Furthermore, a tooth groove corresponding to the tooth fan is provided on the outer periphery of the top of the heat sink, so that when the hollow bar drives the tooth fan to move, the tooth fan can rotate synchronously, thereby processing dust and cooling the heat sink at the same time.

[0010] Furthermore, bristles are fixedly connected to one side of the hollow bar close to the heat sink, so that dust can be removed when the hollow bar moves along the heat sink.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The external battery structure for the robot can adjust the position of the L-shaped pin rod to be vertical in advance during installation. After the control guide sleeve is connected to the L-shaped pin rod, the electrical connector can be inserted along the plug-in slot. During this period, the electrical connector automatically abuts against the elastic electrical connector plate and is automatically electrically connected to the elastic electrical connector plate under the action of external pressure, thereby avoiding the operation connection of additional lines. The torsion bar is automatically contracted when it is blocked by the ring body. When the torsion bar passes over the ring body, it automatically resets under the action of its own torsional force. With the reverse force of the elastic electrical connector plate, the torsion bar is clamped on the left side of the ring body. This design enables the corresponding circuit to be automatically connected when the mobile power block is quickly installed externally, thereby effectively enhancing the convenience of equipment use.

[0013] 2. After the external battery structure for the robot is connected to the main body through the mobile power block, when the main body moves and causes the elastic magnetic block to slide in the corresponding direction, the abutment spring is automatically contracted by the magnetic field of the induced current in the winding harness thereon, so as to pull the hollow bar to use the bristles to move and clean the dust on the heat sink. During this period, due to the synchronous meshing and rotation of the gear fan, it will blow air to the bottom of the hollow bar, and according to the Venturi tube effect, a negative pressure area with air circulation will be formed at the open part of the conical groove, and the dust adhered to the bristles will be sucked into the inner cavity of the hollow bar and discharged downward. At the same time, the surface of the heat sink can also be cooled. This design ensures the safety and stability of the output of the external battery. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The embodiment of the external battery structure for the robot is as follows:

[0022] See also Figure 1-Figure 5The external battery structure for a robot includes a main body 1, a lower wall of the main body 1 is provided with a snap-in groove corresponding to an L-shaped pin rod 4, and the top of the L-shaped pin rod 4 includes an elastic portion extending into the snap-in groove, so as to facilitate pre-positioning of the L-shaped pin rod 4 and improve the accuracy of docking between the main body 1 and the mobile power block 5.

[0023] A plug-in slot 2 is provided on the right wall of the main body 1, and a ring body corresponding to the torsion bar 64 is fixedly installed on the right wall of the inner cavity of the plug-in slot 2, so that when the mobile power block 5 drives the torsion bar 64 to be plugged into the inside of the plug-in slot 2, the mobile power block 5 can be prevented from falling out by the obstruction of the ring body.

[0024] The left inner wall of the plug-in slot 2 is slidably connected with an elastic electrical connection plate 3, and the left wall of the plug-in slot 2 is rotatably connected with an L-shaped pin rod 4 that penetrates the elastic electrical connection plate 3. The right end of the L-shaped pin rod 4 is provided with a guide groove corresponding to the guide sleeve 62, and the inner wall of the guide sleeve 62 includes a strip portion extending into the guide groove, so as to facilitate the use of the clamping mechanism of the two to realize the later removal of the mobile power block 5.

[0025] The right inner wall of the plug-in slot 2 is movably connected to a mobile power block 5, and the left end of the mobile power block 5 is electrically connected to a positioning mechanism 6, which includes an electrical coupling head 61, and the inner wall of the electrical coupling head 61 is rotatably connected to a conductive sleeve 62, and an annular groove is provided on the periphery of the conductive sleeve 62, and the inner wall of the adjusting ring 63 includes a protruding portion extending into the annular groove, so that the conductive sleeve 62 rotates to drive the adjusting ring 63 to move axially accordingly, so as to adjust the locking mechanism of the mobile power block 5.

[0026] The inner wall of the electrical coupling head 61 is slidably connected with an adjustment ring 63 sleeved on the guide sleeve 62. The upper and lower sides of the electrical coupling head 61 are rotatably connected with torsion bars 64. A hinged rod 65 is movably connected between the torsion bar 64 and the adjustment ring 63. By pre-adjusting the position of the L-shaped pin rod 4 to be vertical during installation, the electrical coupling head 61 can be inserted along the plug-in slot 2 after the guide sleeve 62 and the L-shaped pin rod 4 are controlled to dock. During this period, the electrical coupling head 61 automatically abuts against the elastic electrical connection plate 3 and is automatically electrically connected to the elastic electrical connection plate 3 under the action of external pressure, avoiding the operation connection of additional lines. The torsion bar 64 is automatically retracted due to the obstruction of the ring body. When the torsion bar 64 passes over the ring body, it automatically resets under the action of its own torsional force. With the reverse force of the elastic electrical connection plate 3, the torsion bar 64 is clamped on the left side of the ring body. This design enables the corresponding circuit to be automatically connected when the mobile power block 5 is installed externally, thereby effectively enhancing the convenience of equipment use.

[0027] The heat dissipation mechanism 7 is movably connected to the right wall of the mobile power block 5. The heat dissipation mechanism 7 includes a heat sink 71. The top periphery of the heat sink 71 is provided with tooth grooves corresponding to the tooth fan 74, so that when the hollow bar 72 drives the tooth fan 74 to move, the tooth fan 74 can rotate synchronously, thereby processing dust and cooling the heat sink 71 at the same time.

[0028] A hollow bar 72 is slidably connected to the periphery of the heat sink 71, and a brush is fixedly connected to the side of the hollow bar 72 close to the heat sink 71, so that dust can be removed when the hollow bar 72 moves along the heat sink 71. Conical grooves 73 are evenly arranged on the inner wall of the hollow bar 72 close to the heat sink 71, and a tooth fan 74 is rotatably connected to the upper wall of the inner cavity of the hollow bar 72. An abutment spring 75 is fixedly connected between the hollow bar 72 and the side wall of the mobile power block 5, and an elastic magnetic block 76 is slidably connected to the inner wall of the right side of the mobile power block 5. A winding harness 77 extending to the abutment spring 75 is buried on the side of the inner wall of the mobile power block 5 close to the elastic magnetic block 76.

[0029] After the mobile power block 5 is connected to the main body 1, when the main body 1 moves and causes the elastic magnetic block 76 to slide in the corresponding direction, the abutment spring 75 is automatically contracted by the magnetic field of the induced current in the winding harness 77 thereon, so as to pull the hollow bar 72 to use the bristles to move and clean the dust from the heat sink 71. During this period, due to the synchronous meshing and rotation of the gear fan 74, it will blow air to the bottom of the hollow bar 72, and according to the Venturi effect, a negative pressure area with air circulation will be formed at the open part of the conical groove 73, and the dust adhered to the bristles will be sucked into the inner cavity of the hollow bar 72 and discharged downwardly. At the same time, the surface of the heat sink 71 can also be cooled. This design ensures the safety and stability of the output of the external battery.

[0030] Working principle: When in use, by pre-adjusting the vertical position of the L-shaped pin 4, controlling the guide sleeve 62 to dock with the L-shaped pin 4, the electric connector 61 of the mobile power block 5 can be inserted along the plug slot 2. As the electric connector 61 is continuously pushed into the plug slot 2, the electric connector 61 will automatically abut against the elastic electric connector plate 3, and realize the electrical connection with the elastic electric connector plate 3 under the action of external pressure, and the torsion bar 64 will automatically shrink due to the obstruction of the ring body. When the torsion bar 64 passes over the ring body, it will automatically reset under the action of its own torsional force, and cooperate with the elastic electric connector. The reverse force of the plate 3 is applied, and the torsion bar 64 is clamped on the left side of the ring body. This design enables the corresponding circuit to be automatically connected when the mobile power block 5 is installed externally, thereby effectively enhancing the convenience of the device. When the mobile power block 5 needs to be disassembled, the L-shaped pin 4 is deflected in the corresponding direction, so that the guide sleeve 62 drives the adjustment ring 63 to move to the right. At this time, the hinge rod 65 is pulled, so that the torsion bar 64 overcomes the reverse force of the elastic electric connection plate 3 and shrinks toward the side wall of the electric connection head 61. When the torsion bars 64 on both sides are When the retracted distance is smaller than the diameter of the ring body, the mobile power block 5 can be automatically pushed outwards and disengaged under the reverse force of the elastic electric connection plate 3. Since a greater force needs to be applied to the elastic electric connection plate 3 again during this process, the mobile power block 5 can be prevented from accidentally disengaging. In addition, after the mobile power block 5 is connected to the main body 1, when the main body 1 performs various movements and causes the elastic magnetic block 76 to slide in the corresponding direction, the corresponding winding bundle 77 can then generate a gradually increasing induced current, and the corresponding abutting spring 75 is affected by the magnetic field of the winding bundle 77 thereon. Then it automatically contracts and pulls the hollow bar 72 to move. The hollow bar 72 uses the bristles on its side wall to clean the dust from the heat sink 71. During this period, due to the synchronous meshing and rotation of the toothed fan 74, it will blow air to the bottom of the hollow bar 72. According to the Venturi tube effect, a negative pressure area with air circulation will be formed at the open part of the conical groove 73. The dust adhered to the bristles is sucked into the inner cavity of the hollow bar 72 and discharged downward. At the same time, the surface of the heat sink 71 can also be cooled. This design ensures the safety and stability of the external battery output.
