DETAILED DESCRIPTION

[0037] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0038] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0039] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0040] This embodiment provides a battery compartment for a robot. In this embodiment, the robot is a robot dog. In other embodiments, the robot may be a robot of other types or shapes, such as a quadruped or multi-legged robot, or an industrial robot, etc. The robot is powered by a battery pack, which is detachably disposed in the battery compartment.

[0041] See also Figure 1 and Figure 2 The battery compartment includes a compartment shell 11, a compartment door 12 for closing or opening the compartment shell 11, and a push-pull mechanism 13 disposed in the compartment shell 11. When in use, the battery pack 20 is inserted into the compartment shell 11. The compartment shell 11 is provided with a power-on terminal (not shown) connected to the conductive terminal 21 of the battery pack 20. When the battery pack 20 is fully inserted into the compartment shell 11, the conductive terminal 21 contacts the power-on terminal to achieve electrical connection. The compartment shell 11 forms a receiving cavity 111 for receiving the battery pack 20. An opening 112 is provided on one side of the compartment shell 11 for inserting the battery pack 20 into the receiving cavity 111. In this embodiment, the opening 112 is arranged on the side of the compartment shell 11. The compartment door 12 is used to close or open the opening 112.

[0042] The battery pack is detachably arranged in the battery compartment, so as to be fixed on the robot and provide power to the robot. Since the battery pack is arranged in the battery compartment, the battery compartment is locked with the robot, so that it is unnecessary to arrange a connection lock on the battery pack, thereby reducing the cost of the battery pack.

[0043] The bin door 12 in this embodiment can be flipped downward relative to the bin housing 11 to open the bin housing 11. Specifically, the bin door 12 is connected to the bottom wall of the bin housing 11 via a first shaft connection structure. Specifically, a shaft hole 113 is formed on the bin housing 11, and a shaft portion 121 is protruded from the bin door 12 and can be inserted into the shaft hole 113. Of course, in other embodiments, the bin door 12 and the bin housing 11 can also be connected in other ways.

[0044] It should be noted that a locking structure is provided between the door 12 and the housing 11. The locking structure is arranged on a side away from the first shaft connection structure. Specifically, the locking mechanism includes a locking tongue 161, a locking groove 162 that cooperates with the locking tongue 161 to achieve a locking function, and a switch 163 that drives the locking tongue 161 to move relative to the locking groove 162 (see Figure 2and Fig. 9 A lock tongue groove (not numbered) is formed on one side of the door 12 away from the first shaft connection structure. The lock tongue 161 is installed in the lock tongue groove 162. The switch 163 is installed in the door 12. An assembly opening (not shown) for exposing the switch 163 is provided on the door 12. The lock tongue groove 162 is arranged on the housing 11 at a position corresponding to the lock tongue 161.

[0045] The push-pull mechanism 13 pushes the battery pack 20 out of the compartment shell 11 or pushes the battery pack 20 into the compartment shell 11, wherein when the compartment door 12 is closed, the compartment door 12 resists the push-pull mechanism 13 and presses and fixes the battery pack 20 in the compartment shell 11, and when the battery pack 20 is fixed in the compartment shell 11, the conductive terminals 21 of the battery pack 20 contact the power terminals in the compartment shell 11 to achieve electrical connection.

[0046] When the compartment door 12 is closed, the compartment door 12 presses against the push-pull mechanism 13, and the battery pack 20 is pressed and fixed in the compartment shell 11 through the push-pull mechanism 13, so that the battery pack 20 can be locked in the compartment shell 11 without the need to provide an additional connecting lock on the battery pack 20.

[0047] Since there is no need to set a connection lock on the battery pack 20, it helps to reduce the cost of the battery pack 20. In addition, in the design of the battery pack 20, the space originally required to be reserved for the connection lock is saved, and the space originally used to arrange the connection lock can be converted into a space for storing battery cells, thereby helping to expand the internal storage space of the battery pack 20, allowing more battery cells to be arranged, and improving the battery life of the battery pack 20. In addition, since the battery pack 20 is pressed and fixed in the compartment shell 11 by the push-pull mechanism 13, the battery pack 20 and the battery compartment are more versatile.

[0048] In one embodiment, the push-pull mechanism 13 is used to move the battery pack 20 out of the compartment housing 11 or push the battery pack 20 into the compartment housing 11 through the action of an external force. The push-pull mechanism 13 includes a sliding portion 131 disposed in the compartment housing 11, and the battery pack 20 is placed on the sliding portion 131. When an external force acts on the sliding portion 131, the battery pack 20 slides in the compartment housing 11 along with the sliding portion 131, thereby bringing the battery pack 20 out of the compartment housing 11 or bringing it into the compartment housing 11.

[0049] In order to reduce the friction between the sliding part 131 and the housing 11, a sliding block is formed on one of the sliding part 131 and the bottom wall of the housing 11, and the sliding block extends along the sliding direction of the battery pack 10. Specifically, the sliding part 131 includes a sliding plate 1311 that can slide relative to the housing 11, and the battery pack 20 is placed on the sliding plate 1311 and moves with the sliding plate 1311. The sliding bar 114 is on the bottom wall of the housing 11.

[0050] In order to prevent the battery pack 20 from moving out of the compartment housing 11 along with the sliding plate 1311, and to prevent the battery pack 20 from being unable to move along with the sliding plate 1311 due to inertia and the connection force between the conductive terminal 21 and the power-on terminal, the sliding portion 131 also includes a push plate 1312 that is perpendicular or substantially perpendicular to the sliding plate 1311, and the push plate 1312 is located at the rear end of the sliding plate 1311. When the battery pack 20 is placed on the sliding plate 1311, the push plate 1312 is located at the rear of the battery pack 20, so that when the sliding plate 1311 moves out of the compartment housing 11, the push plate 1312 pushes against the battery pack 20 to prevent the battery pack 20 from not moving along with the sliding plate 1311. In this embodiment, the sliding plate 1311 and the push plate 1312 are integrally formed.

[0051] Of course, in other embodiments, the push-pull mechanism 13 can also be composed of a pop-up component and a push-in component. The pop-up component can be a spring, etc., which can be arranged on the rear side of the battery pack 20, between the battery pack 20 and the compartment shell 11. When the battery pack 20 is fixed to the compartment shell 11, the elastic component is compressed to achieve energy storage, and when the compartment door 12 is opened, the elastic component pushes the battery pack 20 out of the compartment shell 11. The push-in component can be arranged on the compartment door 12. When the compartment door 12 is closed, the push-in component applies pressure to the battery pack 20, pushing the battery pack 20 to move toward the compartment shell 11. When the compartment door 12 is closed, the battery pack 20 is completely pushed into the battery pack 20 by the push-in component. At this time, the elastic component is compressed to achieve energy storage, and the conductive terminal 21 and the power-on terminal are electrically connected. The specific structure of the pop-up component and the push-in component will not be described in detail here, as long as the structure can achieve this function.

[0052] As described above, the push-pull mechanism 13 is used to remove the battery pack 20 from the compartment housing 11 or push the battery pack 20 into the compartment housing 11 through the action of an external force, and in this embodiment, the external force is applied by an operator. In order to facilitate the operator to apply external force, a handle 14 is provided at the front end of the sliding plate 1311. In this embodiment, the handle 14 is a part of the push-pull mechanism 13.

[0053] In addition to being convenient for the operator to apply external force, the handle 14, the sliding plate 1311 and the push plate 1312 are arranged to form an assembly space (not numbered) for accommodating the battery pack 20. When the compartment door 12 is closed, the handle 14 and the push plate 1312 press against both sides of the battery pack 20 in the moving direction of the battery pack 20. Specifically, when the compartment door 12 is closed, the compartment door 12 presses against the handle 14, and the handle 14 presses and fixes the battery pack 20 in the compartment housing 11.

[0054] In one embodiment, the handle 14 and the sliding plate body 1311 are connected via a second shaft connection structure. Specifically, the handle 14 and the sliding plate body 1311 are both provided with a rotating shaft hole 151 (see Figure 2 and Figure 3 ), a rotating shaft 152 is installed in the rotating shaft hole 151 of the handle 14 and the sliding plate body 1311, so that the handle 14 can be flipped outward relative to the sliding part 131. When the battery pack 20 needs to be pulled out of the compartment housing 11, the operator flips the handle 14 outward and applies an outward dragging force, thereby driving the sliding part 131 to slide out of the compartment housing 11 until the battery pack 20 slides to a position where it can be taken out, and then the battery pack 20 is taken away; when the battery pack 20 needs to be pushed into the compartment housing 11, the operator can apply a thrust on the handle 14, thereby pushing the sliding part 131 to drive the battery pack 20 into the compartment housing 11 until the conductive terminal 21 and the power-on terminal are electrically contacted, and then flip the handle 14 and close the compartment door 12.

[0055] In the above manner, the handle 14 is flipped upward by the operator applying an external force. Of course, in other embodiments, an elastic member such as a torsion spring can be provided between the handle 14 and the sliding portion 131, so that when the external force is removed, the handle 14 automatically flips upward. By such a configuration, when closing the compartment door 12, there is no need to apply a force on the handle 14, and the compartment door 12 only needs to be flipped. However, if the handle 14 is driven to reset (flip upward) by the elastic member, when the battery pack 20 is placed on the sliding portion 131, the handle 14 may be flipped excessively due to the elastic member, that is, the angle formed between the handle 14 and the sliding plate body 1311 is an acute angle, which will cause trouble to the subsequent placement of the battery pack 20. Specifically, before the battery pack 20 needs to be placed on the sliding plate body 1311, the handle 14 needs to be flipped outward before the battery pack 20 can be inserted.

[0056] See also Figures 3 to 6 In this embodiment, no elastic member such as a torsion spring is provided between the handle 14 and the sliding portion 131. In order to close the door 12, no additional force is required on the handle 14, and the door 12 can be closed by simply flipping it upward. The method adopted in this embodiment is that an actuating portion 122 for driving the handle 14 to flip upward is formed on one end of the door 12 close to the first shaft connection structure.

[0057] Specifically, the actuating portion 122 is an inclined surface formed at one end of the compartment door 12 close to the first axis connection structure and facing the opening 112. In the height direction of the battery compartment, the actuating portion 122 is higher than the bottom wall of the compartment shell 11, and when the compartment door 12 is closed, the position of the actuating portion 122 is higher than the second axis connection structure. In other embodiments, the inclined surface may also be an arc-shaped surface. In order to facilitate the flipping of the handle 14 under the drive of the inclined surface, in this embodiment, an abutting surface 141 is formed on the back of the handle 14, and the abutting surface 141 and the actuating portion 122 abut against each other to drive the handle 14 to flip upward. The slopes of the abutting surface 141 and the actuating portion 122 are both 45°. When the handle 14 is placed horizontally, the abutting surface 141 faces downward.

[0058] In one embodiment, a limiting member is formed between the door 12 and the housing body 11. The limiting member abuts against the door 12 after the door 12 is flipped downward so that the inner wall of the door 12 is parallel to the bottom wall of the housing body 11. The abutting surface 141 abuts against the inner wall of the door 12 after the handle 14 is flipped so that an acute angle (such as 100°) is formed between the handle 14 and the door 12. Figure 6 As shown). This arrangement makes it convenient to hold the handle 14. The limiting structure includes a first limiting surface 123 formed on the door 12 and a second limiting surface 115 formed on the housing 11. When the door 12 is in a horizontal position, the first limiting surface 123 and the second limiting surface 115 are both vertical and abut against each other to prevent the door 12 from turning downward again. The limiting component can also have other structures, which are not given as examples here.

[0059] As described above, after the battery pack 20 is inserted into the compartment housing 11, the conductive terminal 21 and the power-on terminal are in electrical contact. At the moment when the battery pack 20 is pulled out, a reverse force (i.e., the connection force between the two) occurs between the conductive terminal 21 and the power-on terminal to prevent the battery pack 20 from being pulled out. In order to separate the conductive terminal 21 and the power-on terminal by applying a small force on the handle 14, in one embodiment, the handle 14 has a rotation point 142 that is rotationally connected to the sliding portion 131, and a contact point 143 formed at the bottom end of the handle 14. When the handle 14 is not flipped downward, the contact point 143 presses against the bottom wall of the compartment housing 11. The distance between the grip portion 144 and the rotation point 142 is greater than the distance between the contact point 143 and the rotation point 142. By limiting the distances among the gripping portion 144, the rotation point 142 and the contact 143, the handle 14 is used as a lever. Thus, when the handle 14 is rotated, the contact 143 rotates around the rotation point 142, and the handle 14 applies a thrust on the contact 143 relative to the bin shell 11, which helps to increase the separation between the conductive terminal 21 and the power-carrying terminal.

[0060] In this embodiment, please refer to Figures 3 to 5The handle 14 includes a body 145 and a shaft portion 146 formed at the lower end of the body 145. The grip portion 144 is located on the body 145 on a side away from the shaft portion 146. The shaft hole 113 is formed on the shaft portion 146. In order to facilitate the rotation of the shaft portion 146, the handle 14 is provided with a plurality of holes 113. Figure 1 In the state), the contact point 143 is located outside the axis of the rotating shaft portion 146. The rotating shaft portion 146 has a cam-like structure. An escape groove 116 for accommodating the rotating shaft portion 146 is formed in the housing 11, and the side surface of the escape groove 116 connecting with the rotating shaft portion 146 is an arc surface (not numbered).

[0061] See above. Figures 4 to 6 , the position of the actuating portion 122 is higher than the second shaft connection structure. In order to avoid interference between the actuating portion 122 and the sliding plate body 1311, in this embodiment, two convex strips 124 extending along the height direction of the warehouse door 12 are formed on the inner side of the warehouse door 12, and a sliding space 125 is formed between the two convex strips 124. The bottom surface of the sliding space 125 is on the same horizontal plane as the bottom wall of the warehouse shell body 11. The sliding space 125 is used for the sliding plate body 1311 to move. Abutment surfaces 141 are formed on the lower end surface of the main body 145. In this embodiment, there are two abutment surfaces 141. In the height direction of the handle 14, the projections of the two abutment surfaces 141 are respectively located on both sides of the rotating shaft portion 146. When the handle 14 is flipped over, the abutment surfaces 141 abut against the convex strips 124, so that the handle 14 is tilted and positioned on the warehouse door 12 ( Figure 6 As shown), the handle 12 can slide on the convex strip 124. It should be noted that the actuating portion 122 is an inclined surface formed on the end of the convex strip 124.

[0062] See above. Figure 1 , Figure 2 and Figure 4 The battery pack 20 moves in the warehouse shell 11 through the sliding portion 131. In order to prevent the sliding portion 131 from sliding out of the warehouse shell 11 when moving toward the outside of the warehouse shell 11, causing the battery pack 20 to fall and thus cause damage to the battery pack 20, in this embodiment, a limiting structure is arranged between the warehouse shell 11 and the sliding portion 131. Specifically, a support plate 17 is provided in the battery warehouse, and a sliding plate body 1311 is arranged between the support plate 17 and the bottom wall of the warehouse shell 11. The support plate 17 is recessed forward from its rear end to form a sliding limiting groove 171 extending along the sliding direction of the sliding plate body 1311. The push plate 1312 is arranged in the sliding limiting groove 171, and the sliding limiting groove 171 and the push plate 1312 form the above-mentioned limiting structure. By cooperating with the sliding limit groove 171 and the push plate 1312 , the push plate 1312 can be fully utilized, so that there is no need to set up an additional limit structure, so that the structure inside the bin shell 11 is simplified.

[0063] In this embodiment, a first foolproof portion 172 is provided in the compartment housing 11, and a second foolproof portion 22 matching the first foolproof portion 172 is formed on the battery pack 20, so as to prevent the battery pack 20 from being inserted in reverse through the first foolproof portion 172 and the second foolproof portion 22. Among them, one of the first foolproof portion 172 and the second foolproof portion 22 is a foolproof groove, and the other is a foolproof strip. The first foolproof portion 172 is formed on the support plate 17, and one of the first foolproof portion 172 and the second foolproof portion 22 is a long strip structure extending along the moving direction of the sliding plate body 1311.

[0064] The first fool-proofing part 172 is specifically a fool-proofing strip 172, and there are two fool-proofing strips 172. The two fool-proofing strips 172 are formed by extending upward from both sides of the support plate 17. Each fool-proofing strip 172 is formed with an inclined surface (unnumbered) facing the other fool-proofing strip 172. The second fool-proofing part 22 is specifically a fool-proofing groove 22, and correspondingly, there are also two fool-proofing grooves 22. The two fool-proofing grooves 22 are formed on the bottom surface of the battery pack 20, specifically on the side of the bottom surface of the battery pack 20. When the battery pack 20 is installed in the battery compartment, the two fool-proofing strips 172 are respectively located at the outermost sides of the bottom surface of the battery pack 20. Such a configuration can make the structure between the battery compartment and the battery pack 20 more compact.

[0065] The battery compartment works as follows: When you need to remove the battery pack 20, Figure 4 and Figure 6 , the door 12 is opened, the handle 14 is turned outward under the action of external force, and the abutting surface 141 abuts against the convex strip 124, so that a certain angle is formed between the handle 14 and the door 12, and the state of the handle 14 changes from Figure 4 The vertical position is transformed into Figure 6 Then drag the handle 14 to move the sliding portion 131 outward in the bin housing 11, when the sliding portion 131 moves to Figure 7 When the position is shown, please combine Figure 7 and Figure 8 The main body 145 of the handle 14 is located outside the compartment door 12, the abutting surface 141 is separated from the convex strip 124, and the handle 14 is flipped downward again, so that the front side of the battery pack 20 is not blocked by the handle 14. At the same time, the push plate 1312 moves to one end of the sliding limit groove 171 and is restricted by the sliding limit groove 171, so that the external force can no longer drag the sliding part 131 to move outward. In this position state, the battery pack 20 can be removed.

[0066] When the battery pack 20 needs to be installed, first place the battery compartment in Figure 8In the state shown, the battery pack 20 is then inserted and placed on the moving part, and the battery pack 20 is pushed. Since the rear side of the battery pack 20 is limited by the push plate 1312, when the battery pack 20 is pushed, the push-pull mechanism 13 will move into the compartment shell 11 together with the battery pack 20. When the body 145 moves onto the compartment door 12, the handle 14 is turned upward due to the mutual cooperation between the abutting surface 141 and the convex strip 124, and the handle 14 is moved from Figure 8 The position is transformed into Figure 6 At this time, the battery pack 20 can be pushed further or the handle 14 can be pushed instead until the battery pack 20 is completely inserted into the compartment housing 11. During this process, when the abutting surface 141 of the handle 14 slides to the actuating portion 122, the handle 14 is flipped upward again to become Figure 4 Finally, the door 12 is flipped upward, and the convex strip 124 of the door 12 abuts against the handle 14.

[0067] This embodiment also provides a body 100 of a multi-legged robot, such as Fig. 9 As shown, it includes a body shell 10 in which the battery compartment 1 of Example 1 is installed and a control component (not shown) arranged in the body shell 10.

[0068] In this embodiment, the structure of the battery compartment 1 is the same as that of the battery compartment 1 in Embodiment 1. The compartment housing is integrated in the body housing 10, and the compartment housing and the compartment door 12 are part of the body housing 10. The battery compartment 1 is arranged transversely on the body housing 10, and the compartment door 12 is located on the right side of the body housing 10.

[0069] By adopting the battery compartment 1 of the first embodiment and closing it with the compartment door 12 , the body 100 can be integrated in appearance.

[0070] This embodiment also provides a multi-legged robot. In this embodiment, the multi-legged robot takes a robot dog as an example. Fig. 9 As shown, the robot dog includes a body 100, a leg assembly 200 assembled on the body 100, and a head assembly 300 assembled on the body 100. The leg assembly 200 includes two front limbs 201 and two rear limbs 202.

[0071] In this embodiment, the structure of the body 100 is the same as the body 100 assembly in Embodiment 2, and the battery compartment 1 is arranged close to the hind legs 202. Such an arrangement allows the battery compartment 1 and the battery pack 20 to form a balance with the head assembly 300, ensuring that the center of gravity of the robot dog is not shifted, thereby avoiding problems such as the robot dog falling over when moving.

[0072] By adopting the battery compartment 1 of Example 1, since there is no need to set a connecting lock on the battery pack 20, the space originally used for the connecting lock of the battery pack 20 is released, and the locking space can be converted into a space for storing battery cells, which helps to expand the internal accommodation space of the battery pack 20 and increase the energy storage capacity of the battery pack 20. When the battery pack 20 is applied to the robot dog, it helps to improve the endurance of the robot dog.

[0073] In addition, currently, the battery pack 20 is usually used as an accessory of the robot dog. After long-term use, the storage capacity of the battery pack 20 decreases and the battery pack 20 needs to be replaced. However, due to the structure of the battery compartment 1 of Example 1, the adapted battery pack 20 does not need to be provided with a connection lock, which is conducive to reducing the cost of the battery pack 20. In other words, the use of the battery compartment 1 of Example 1 helps to reduce the replacement cost of the battery pack 20. In addition, since the battery pack 20 is pressed and fixed in the compartment shell 11 by the push-pull mechanism 13, the adaptability of the robot is improved.

[0074] Obviously, the embodiments described above are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the present invention.
