[0029] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0030] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0032] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0034] According to one embodiment of this application, a power supply mechanism is provided. For example... Figures 1 to 5 As shown, the power supply mechanism includes a housing 1 and a battery body 2. The housing 1 has a mounting cavity 11, and a connector 12 is provided on the inner wall of the mounting cavity 11. The battery body 2 is snapped into the mounting cavity 11, and the battery body 2 has a connector 29, into which the connector is inserted. A sealing element 3 is provided between the battery body 2 and the inner wall of the mounting cavity 11.

[0035] In this example, the battery body 2 is snapped into the mounting cavity 11 of the housing 1, and a sealing element 3 is provided between the battery body 2 and the inner wall of the mounting cavity 11. This enables the design of quick replacement of the battery body 2, and also gives the housing 1 good sealing and protection performance for the battery body 2, such as dustproof and waterproof.

[0036] In this example, the mounting cavity 11, apart from the opening for assembling and disassembling the battery body 2, is a sealed cavity; that is, the mounting cavity 11 has only one opening for assembling and disassembling the battery body 2, which helps to improve the sealing performance of the mounting cavity 11. The seal 3 can be located near the opening of the mounting cavity 11.

[0037] It should be noted that the inner wall of the mounting cavity 11 is provided with a connector 12, and the battery body 2 is provided with a connector 29. After the battery body 2 is installed in place, the connector 12 can be stably inserted into the connector 29, so that the battery body 2 can be electrically connected to electronic devices outside the mounting cavity 11. By setting the connector 12 to be inserted into the connector 29, the use of wire harness connection can be avoided. The electrical connection can be completed when the battery body 2 is assembled into the mounting cavity 11, which helps to improve the assembly speed of the battery body 2 and saves the assembly time of the battery body 2.

[0038] The connector 12 can be a knife-type connector, or a pogo pin (spring pin precision connector) or other types of electrical interface. Those skilled in the art can determine the appropriate form based on the specific circumstances; no specific limitations are made here.

[0039] It should also be noted that the sealing element 3 is sleeved on the outer periphery of the battery body 2, and the end of the sealing element 3 facing away from the battery body 2 can abut against the inner wall of the mounting cavity 11. That is, the inner wall of the sealing element 3 abuts against the battery body 2, and the outer wall of the sealing element 3 abuts against the inner wall of the mounting cavity 11, thereby achieving a good sealing effect. The sealing element 3 can be made of a flexible material, and can be deformed under pressure, thereby facilitating the disassembly and installation of the battery body 2, and also better filling the gap between the battery body 2 and the inner wall of the mounting cavity 11 to improve the sealing effect. For example, the sealing element 3 can be rubber or engineering plastic, etc., which can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0040] In this example, the battery body 2 is snapped into the mounting cavity 11, enabling quick installation and removal of the battery body 2 to save replacement time. For example, one of the battery body 2 and the housing 1 has a buckle 21, and the other has a corresponding slot 111, wherein the buckle 21 can be inserted into or detached from the slot 111. For example, the battery body 2 may be provided with a buckle 21, and the inner wall of the mounting cavity 11 may be provided with a slot 111, allowing the buckle 21 to be inserted into or detached from the slot 111. Alternatively, a slot 111 may be provided on the outer wall of the battery body 2, and the housing 1 may have a corresponding buckle 21. Those skilled in the art can determine the appropriate configuration based on the specific circumstances, and no specific limitations are made here.

[0041] In one example, such as Figure 1 and Figure 2As shown, the sealing element 3 is sleeved on the outer periphery of the battery body 2.

[0042] like Figure 1 and Figure 2 As shown, in this example, the seal 3 can be a sealing ring structure, and the seal 3 can be fixedly sleeved on the outer periphery of the battery body 2. After the battery body 2 is assembled into the mounting cavity 11, the outer wall of the seal 3 can abut against the inner wall of the mounting cavity 11, thereby achieving a seal between the battery body 2 and the housing 1.

[0043] In this example, the seal 3 can be a flexible component made of materials such as rubber or engineering plastics, allowing it to fit snugly against the outer wall of the battery body 2. Alternatively, the seal 3 can include a metal sealing ring fitted onto the battery body 2, with a flexible component on its outer wall. Alternatively, the seal 3 can be a sealing strip structure, which can be bonded circumferentially around the battery body 2. Of course, the specific structure of the seal 3 can be determined by those skilled in the art based on actual conditions, and is not specifically limited here.

[0044] In this example, the outer wall of the seal 3 has a circumferentially protruding ring. During assembly of the battery body 2, the ring can deform under pressure from the opening of the mounting cavity 11, facilitating the smooth assembly of the battery body 2 into the mounting cavity 11. After the battery body 2 is assembled into the mounting cavity 11, the ring abuts against the inner wall of the mounting cavity 11 to form a seal. Multiple rings can be spaced apart to improve the sealing effect.

[0045] It should be noted that the sealing element 3 can also be fixedly disposed on the inner wall of the mounting cavity 11. After the battery body 2 is assembled into the mounting cavity 11, the inner wall of the sealing element 3 can abut against the outer wall of the battery body 2, thereby achieving a sealing effect. Of course, the specific arrangement of the sealing element 3 can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0046] In one example, such as Figures 1 to 3 As shown, the battery body 2 is also movably provided with a buckle 21, and the inner wall of the mounting cavity 11 is provided with a corresponding slot 111, and the buckle 21 can be inserted into or detached from the slot 111.

[0047] like Figures 1 to 3 As shown, in this example, the latch 21 is movably disposed on the battery body 2. For example, the latch 21 can be telescopically disposed relative to the battery body 2. That is, when the battery body 2 is assembled into the mounting cavity 11, the latch 21 extends out of the battery body 2 to insert into the slot 111, thereby forming a latch. When it is necessary to remove the battery body 2 from the mounting cavity 11, the latch 21 can retract into the battery body 2 to disengage from the slot 111, thereby allowing the battery body 2 to be smoothly removed from the mounting cavity 11.

[0048] In this example, the battery body 2 is further provided with a first elastic element, which can push the buckle 21 into the slot 111. By pushing the buckle 21 to move and insert it into the slot 111 through the first elastic element, the stability of the buckle 21 entering the slot 111 can be improved, and the ease of assembly of the battery body 2 can also be improved. The first elastic element can be a spring or a torsion spring, etc., which can be determined by those skilled in the art according to the actual situation, and is not specifically limited here.

[0049] It should be noted that multiple first elastic elements can be provided at intervals. By using multiple first elastic elements to push the buckle 21 into the card slot 111, the stability of the buckle 21 entering the card slot 111 can be further improved. For example, two, three, or four first elastic elements can be provided, etc., which can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0050] like Figure 1 and Figure 2 As shown, in this example, the battery body 2 also includes an unlocking block 22, which is slidably disposed, and a latch 21 is connected to the unlocking block 22. A first elastic element is provided inside the battery body 2, and the unlocking block 22 abuts against the first elastic element. The first elastic element can push the unlocking block 22 to push the latch 21 out of the battery body 2. Furthermore, the user can move the unlocking block 22 to compress the first elastic element, and the unlocking block 22 will cause the latch 21 to retract into the battery body 2. The latch 21 can be integrally formed with the unlocking block 22, or the latch 21 can be connected to the unlocking block 22 by welding or fastener screws, etc. Those skilled in the art can determine the appropriate method based on the actual situation, and no specific limitation is made here.

[0051] It should also be noted that the sealing element 3 is sleeved on the outer periphery of the battery body 2, and the sealing element 3 is provided with a clearance hole to avoid the buckle 21, that is, the buckle 21 can be inserted into the clearance hole.

[0052] In one example, the battery body 2 is provided with multiple buckles 21, and the inner wall of the mounting cavity 11 is provided with multiple slots 111. By providing multiple buckles 21, the stability of the battery body 2 being secured to the housing 1 can be achieved.

[0053] like Figure 1 As shown, in this example, two latches 21 can be provided, with the two latches 21 located on opposite sides of the battery body 2. The inner wall of the mounting cavity 11 has slots 111 on the corresponding sides. Each latch 21 is connected to an unlocking block 22. The user can apply pressure to the two unlocking blocks 22 simultaneously with two fingers, which will cause the latches 21 on both sides to retract into the battery body 2.

[0054] Of course, more clips 21 can be set, such as three or four, as can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0055] like Figure 5 As shown, it should be noted that the buckle 21 can also be provided on the housing 1, and the housing 1 is also provided with an unlocking component connected to the buckle 21. The outer wall of the battery body 2 is provided with a corresponding slot 111. The buckle 21 on the housing 1 can be inserted into the slot 111 on the battery body 2, thereby also enabling the battery body 2 to be stably assembled in the mounting cavity 11.

[0056] In one example, such as Figure 3 As shown, the inner wall of the mounting cavity 11 is provided with a guide portion 112, and the battery body 2 can move along the guide portion 112.

[0057] In this example, the battery body 2 can be slidably inserted into the mounting cavity 11 from the opening of the mounting cavity 11. During the sliding process, the battery body 2 can slide along the guide groove, thereby improving the convenience of assembling or disassembling the battery body 2 and avoiding the battery body 2 from being stuck.

[0058] The guide portion 112 can be a guide groove provided on the inner wall of the mounting cavity 11, and a guide rail is correspondingly provided on the outer wall of the battery body 2. For example, the edge of the battery body 2 can be embedded in the guide groove and move along the guide groove, thereby playing a guiding role. Alternatively, the guide portion 112 can also be a guide rail provided on the inner wall of the mounting cavity 11, and a guide groove is correspondingly provided on the outer wall of the battery body 2. Furthermore, multiple guide portions 112 can be provided to improve the guiding effect, thereby further improving the smoothness of the movement of the battery body 2. Of course, the specific structure, position, and number of the guide portions 112 can be determined by those skilled in the art according to the actual situation, and are not specifically limited here.

[0059] In one example, such as Figure 3 As shown, the inner wall of the mounting cavity 11 is provided with a positioning post 114, which can position the battery body 2.

[0060] like Figure 3 As shown, in this example, the positioning post 114 can be disposed on the bottom wall of the mounting cavity 11 to position the battery body 2 during assembly, thereby improving the assembly accuracy of the battery body 2. For example, a positioning groove is provided at the end of the battery body 2 facing the bottom wall. When the battery body 2 moves into the mounting cavity 11, the positioning post 114 can be inserted into the positioning groove, thus having the functions of positioning and limiting.

[0061] The positioning posts 114 can be cylindrical, conical, prism, pyramidal, or similar shapes. Furthermore, multiple positioning posts 114 can be spaced apart; for example, two, three, or four positioning posts 114 can be spaced apart. Of course, the specific shape and number of the positioning posts 114 can be determined by those skilled in the art based on actual circumstances, and no specific limitations are made here.

[0062] In one example, such as Figure 3 As shown, the battery body 2 is movable relative to the housing 1 to engage with or disengage from the mounting cavity 11. Along the moving direction of the battery body 2, a second elastic element 113 is provided between the battery body 2 and the inner wall of the mounting cavity 11.

[0063] like Figure 3 As shown, in this example, the second elastic member 113 can be disposed on the bottom wall of the mounting cavity 11. When the battery body 2 is moved and assembled into the mounting cavity 11, one end of the battery body 2 can abut against the second elastic member 113. After the battery body 2 is assembled in place, the battery body 2 presses against the second elastic member 113, causing the second elastic member 113 to compress. When it is necessary to remove the battery body 2 from the mounting cavity 11, the latch 21 is first unlocked, and the second elastic member 113 can push the battery body 2 outward, thereby assisting in pushing it out and improving the ease of disassembling the battery body 2.

[0064] The second elastic element 113 can be a spring or an elastic block, etc. Furthermore, multiple second elastic elements 113 can be provided to improve the pushing effect on the battery body 2; for example, two, three, or four second elastic elements 113 can be provided at intervals. Of course, the specific structure and number of the second elastic elements 113 can be determined by those skilled in the art based on actual conditions, and no specific limitations are made here.

[0065] It should be noted that the second elastic element 113 can also be disposed at one end of the battery body 2. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0066] In one example, such as Figure 1 and Figure 2 As shown, the battery body 2 is also provided with a status display module 23, which is used to display the status of the battery body 2.

[0067] In this example, the battery body 2 includes a battery cell 25 and a battery plate 26. The battery plate 26 is electrically connected to the battery cell 25, and a connector 29 is provided on the battery plate 26. The status display module 23 is electrically connected to the battery plate 26. The status display module 23 can be used to display the remaining power of the battery cell 25, or the usage status of the battery body 2, etc. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0068] like Figure 2 As shown, it should be noted that the status display module 23 includes a display panel 231, a light guide column 232, and indicator lights 233. There are multiple indicator lights 233, and different indicator lights 233 illuminate to represent different signals, such as low battery power of the battery body 2, the battery body 2 being in an on or off state, etc., which can be displayed on the display panel 231 through the light guide column 232.

[0069] like Figure 1 and Figure 2 As shown, it should also be noted that the battery body 2 is equipped with a power switch 24, which is used to control the opening and closing of the battery body 2 by pressing the power switch 24. When the battery body 2 is open, it can be used to supply power to external devices. When the battery body 2 is closed, it cannot supply power to external devices. The battery body 2 can be closed when it needs to be removed from the mounting cavity 11 or when it needs to be installed into the mounting cavity 11 to ensure user safety.

[0070] like Figure 1 and Figure 2 As shown, the battery body 2 also includes a first outer shell 27 and a second outer shell 28, which surround each other to form an inner cavity, in which the battery cell 25 and the battery plate 26 are disposed. The first outer shell 27 or the second outer shell 28 can be made of a metallic material, thereby improving heat dissipation.

[0071] It should also be noted that the battery body 2 further includes a mounting block, with one end of the first outer shell 27 and the second outer shell 28 connected to the mounting block. The latch 21 is slidably mounted on the mounting block. The power switch 24 and the status display module 23 are mounted on the mounting block, and the mounting block allows one end of the power switch 24 and the status display module 23 to protrude outside the mounting cavity 11. The seal 3 can also be fitted onto the outer periphery of the mounting block.

[0072] According to a second aspect of this utility model, a robot 10 is provided. For example... Figure 6 As shown, the robot 10 includes the power supply mechanism described in the above embodiment. The power supply mechanism includes a housing 1 and a battery body 2. The housing 1 has a mounting cavity 11, and a connector 12 is provided on the inner wall of the mounting cavity 11. The battery body 2 is snapped into the mounting cavity 11. The battery body 2 has a connector 29, and the connector is inserted into the connector 29. A sealing element 3 is provided between the battery body 2 and the inner wall of the mounting cavity 11. The design of the battery body 2 being snapped into the mounting cavity 11 of the housing 1, and the sealing element 3 between the battery body 2 and the inner wall of the mounting cavity 11, allows for both quick replacement of the battery body 2 and provides good sealing and protection performance of the housing 1 for the battery body 2, such as dustproof and waterproof.

[0073] In this example, robot 10 includes a body 101, and an installation cavity 11 can be provided inside the body 101. A power supply mechanism is installed inside the body 101 and can supply power to electronic devices inside the body 101 and electrical devices in other locations of robot 10.

[0074] It should be noted that robot 10 can be a legged robot, such as a quadruped or bipedal robot. Alternatively, it can be a wheeled robot. Those skilled in the art can determine the appropriate method based on the specific circumstances, and no specific limitations are made here.

[0075] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.

[0076] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
