Description

Technical Field

[0001] The present application relates to the technical field of robots, and relates to a battery compartment of a robot, a bipedal robot, and a robot. Background Art

[0002] The battery is currently the main energy source of the robot. In the robot structure design, a dedicated battery compartment is often designed in the main body parts such as the torso to place the battery, providing power for various movements and operations of the robot. In the existing battery compartment structure design, in order to meet the stability of the battery in the battery compartment, a limiting structure is provided on the inner wall of the battery compartment. When the battery is installed in the battery compartment, its two sides will be restricted by the limiting structure to maintain the stability of the battery during the operation of the robot.

[0003] The conventional battery compartment is manufactured by sheet metal processing and uses a rigid material to make the limiting structure. Due to the process problem of inaccurate tolerance in the sheet metal processing of the battery compartment, the sizes of the battery accommodation spaces restricted by the limiting structures in the battery compartment are different, which makes it difficult to disassemble and assemble the battery or causes the battery to become loose after being installed.

[0004] If an elastic material such as rubber is used as the limiting structure, although the tolerance compatibility of the battery compartment is improved by using its compression and rebound characteristics, due to the large surface roughness of the elastic material itself, the friction force is large when the battery contacts the limiting structure, resulting in easy jamming during the insertion and removal of the battery, and the disassembly and assembly are not smooth. In addition, the surface of the elastic material such as rubber repeatedly contacts and rubs against the battery shell, which is easy to wear and age, and needs to be replaced frequently, resulting in high material and maintenance costs. Summary of the Invention

[0005] The present application provides a battery compartment of a robot, a bipedal robot, and a robot, aiming to solve the problems of inconvenient disassembly and assembly of the battery in the existing robot battery compartment and poor tolerance compatibility of the compartment structure.

[0006] In one aspect, a battery compartment of a robot is provided, including:

[0007] A generally rectangular compartment body; and two battery limiting components, which are respectively arranged on two side walls of the compartment body in a first direction;

[0008] Wherein, each battery limiting component includes an elastic member and a rigid member. One side of the elastic member abuts against the side wall, the other side of the elastic member abuts against the rigid member, the rigid member does not contact the side wall and there is a gap with a preset distance between the rigid member and the side wall, and the projection of the rigid member in a second direction can cover the elastic member.

[0009] In one embodiment, the projections of the rigid part and the elastic part in the second direction have approximately the same shape, the projection of the rigid part in the second direction is slightly larger than the projection of the elastic part in the horizontal direction, the rigid part is constructed with a rib, and the rib covers part of the outer edge of the elastic part. When the rigid part is subjected to pressure, the elastic part is deformed and then moves a certain distance toward the side wall, whereupon the rib abuts against the side wall.

[0010] In one embodiment, the bin body is constructed with a bin bottom and an opening opposite to the bin bottom, and the battery limiting assembly is disposed adjacent to the opening.

[0011] In one embodiment, the battery limiting assembly is fixedly connected to the side wall via a fastener, and the fastener limits the position of the battery limiting assembly and the side wall in the first direction and the third direction, but does not limit the position in the second direction.

[0012] In one embodiment, a plurality of ridges are formed along a first direction on a side of the rigid member facing away from the elastic member.

[0013] In one solution, the rigid member is configured with an inclined surface adjacent to the opening for guiding the battery to slide.

[0014] In one embodiment, the elastic member is made of rubber or silicone-like material, and the rigid member is made of plastic or metal material.

[0015] In one embodiment, projections of the two battery limiting assemblies in the second direction overlap, and the length of the battery limiting assemblies in the first direction is greater than the length in the third direction.

[0016] In one embodiment, a bipedal robot is provided, comprising the battery compartment of the robot of the aforementioned embodiment.

[0017] In one embodiment, a robot is provided, comprising the battery compartment of the robot of the aforementioned embodiment.

[0018] Beneficial effects of this application:

[0019] The present application covers a rigid part on an elastic part to form a battery limiting assembly. When the battery is loaded into the battery compartment, the outer shell of the battery contacts and slides relatively with the smooth surface of the rigid part. The rigid part squeezes the elastic part under the push of the battery, and the elastic part is deformed and compressed by force, ensuring that the battery slides smoothly into the battery compartment. After the battery is loaded, the elastic part resets and drives the rigid part to squeeze the battery, achieving the limited fixation of the battery. The present application combines the smooth surface and stable structure of the rigid part with the compressible and resilient characteristics of the elastic part, thereby improving the compatibility of the battery accommodation space in the battery compartment with the dimensional tolerances of different individual batteries, while ensuring that the friction resistance between the battery body and the limiting structure is small, and the disassembly and assembly are convenient and smooth.

[0037] In the present application, the concept of "substantially in" describes the main features of an overall structure or shape. When describing the shape of an object, this means that the object mainly presents a certain specific shape, but there may be differences in non-functional details. These detail differences do not affect the overall features and can therefore be classified as "substantially in" a certain shape.

Similarly, when describing a cube, it is described as "substantially cubic", which means that the overall shape of the object is cubic, but there are differences in some non-functional details.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0039] In the present application, unless otherwise clearly specified or limited, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the horizontal height of the first feature is less than that of the second feature.

In addition, without contradiction, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0041] To solve the problems that the battery compartment of the existing robot has inconvenient battery disassembly and assembly and poor tolerance compatibility of the compartment structure, the present application makes improvements and innovations and proposes the following embodiments.

[0042] In one embodiment, please refer to Figures 1 to 5 , a battery compartment of a robot is provided, including a generally rectangular compartment body 1; and two battery limiting components 2, the two battery limiting components 2 are respectively arranged on two side walls 11 of the compartment body 1 in the first direction X, and during the process of loading the battery body 3 into the battery compartment, the battery limiting components 2 clamp and fix the battery body 3 from both sides.

[0043] In this embodiment, the battery limiting component 2 includes an elastic member 21 and a rigid member 22; one side of the elastic member 21 abuts against the side wall 11 of the compartment body 1, and the other side of the elastic member 21 abuts against the rigid member 22, that is, the elastic member 21 is interposed between the rigid member 22 and the side wall 11 as a buffer transition part.

[0044] In this embodiment, the rigid member 22 does not contact the side wall 11 and a gap with a preset distance is provided between the rigid member 22 and the side wall 11. Therefore, when the battery body 3 is being inserted, when the rigid member 22 and the elastic member 21 are squeezed by the battery body 3, with the deformation of the elastic member 21, the rigid member 22 and the elastic member 21 can shrink a certain distance towards the adjacent side wall 11, providing a certain tolerance floating space for the battery body 3; the projection of the rigid member 22 in the second direction Y can cover the elastic member 21, that is, the elastic member 21 does not contact the battery body 3 in its natural state and after being squeezed and deformed.

[0045] Among them, the elastic member 21 refers to a functional part made of an elastic material that deforms in shape under an external force and can return to its original state when the external force disappears, using elasticity to work; the rigid member 22 refers to an object or component that does not undergo obvious deformation when subjected to an external force, and the rigid member 22 usually has relatively high strength and hardness and can obtain a smoother surface during processing.

[0046] Exemplarily, the elastic member 21 can specifically be a processed product of elastic materials such as rubber, silica gel, TPE, TPV, etc.; the rigid member 22 can specifically be a processed product of metal materials such as alloy, steel, etc., or plastic materials such as engineering plastics, general plastics, etc., or composite materials such as glass fiber reinforced plastics, carbon fiber reinforced plastics, etc.

[0047] During the battery insertion operation, the outer shell of the battery body 3 contacts and slides relative to the smooth surface of the rigid member 22. At the same time, the rigid member 22 squeezes the elastic member 21 under the push of the battery, and the elastic member 21 is deformed and compressed by the force, ensuring that the battery smoothly slides into the battery compartment; after the battery is inserted, the elastic member 21 resets and drives the rigid member 22 to squeeze the battery, realizing the limit fixation of the battery.

[0048] Therefore, in this application, by combining the characteristics of the smooth surface and stable structure of the rigid member 22 with the characteristics of the compressible and resilient elastic member 21, the battery compartment can compensate for dimensional tolerances for different battery individuals, while meeting the contact and mating performance between the battery body 3 and the limiting structure, ensuring smooth disassembly and assembly of the battery body 3.

[0049] In one embodiment, please refer to Figure 4 、 Figure 5 and Figure 8 , the shapes of the projections of the rigid member 22 and the elastic member 21 in the second direction Y are substantially the same, and the projection of the rigid member 22 in the second direction Y is slightly larger than the projection of the elastic member 21 in the horizontal direction. Therefore, there is enough contact area between the rigid member 22 and the elastic member 21 to meet the support and force transmission requirements of the battery limiting component 2, and to avoid the situation where when the battery limiting component 2 is squeezed by the battery body 3 due to too small contact area between the rigid member 22 and the elastic member 21, the rigid member 22 tilts and warps with the elastic member 21 as a fulcrum.

[0050] In this embodiment, the rigid member 22 is configured with a flange 221, and the flange 221 covers a part of the outer edge of the elastic member 21. When the rigid member 22 is subjected to pressure, it drives the elastic member 21 to deform. Then, after moving a certain distance toward the side wall 11, the flange 221 abuts against the side wall 11, which can play a limiting protection function for the contraction limit of the battery limiting component 2. Wherein, a clearance is left between the flange 221 and the outer edge of the elastic member 21 for the elastic member 21 to expand and deform.

[0051] In one embodiment, please refer to Figure 6 and Figure 7 , the storage body 1 is configured with a bottom 12 and an opening 13 opposite to the bottom 12, and the battery limiting component 2 is arranged adjacent to the opening 13. During assembly, the battery body 3 is pushed into the inner cavity of the battery compartment from the opening 13 and attached to the bottom 12. After the battery body 3 is pushed in a certain distance, it is clamped and constrained by the battery limiting components 2 on both sides of the storage body 1. That is, at least three faces of the battery body 3 are supported and fixed after assembly.

[0052] In one embodiment, please refer to Figures 1 to 7 , the battery limiting component 2 is fixedly connected to the side wall 11 through a fastener. The fastener limits the positions of the battery limiting component 2 and the side wall 11 in the first direction X and the third direction Z, but does not limit the position in the second direction Y. That is, the fixed connection by the fastener can prevent the friction resistance between the rigid member 22 and the battery body 3 from being too large during the battery assembly process. As the battery body 3 slides in, it drives the rigid member 22 to move together, causing relative movement and misalignment between the rigid member 22 and the elastic member 21, and even causing damage to the structure of the battery limiting component 2. At the same time, the fixed connection method of the fastener does not affect the compression and rebound action of the battery limiting component 2 after being stressed.

[0053] In one embodiment, please refer to Figure 8 , a plurality of convex ribs 222 are formed on the side of the rigid member 22 facing away from the elastic member 21 along the first direction X. By using the convex ribs 222 to abut against the battery body 3, the contact area between the rigid member 22 and the battery body 3 can be reduced while meeting the requirements of support and force transmission, thereby reducing the friction resistance between the battery body 3 and the rigid member 22 during battery insertion and removal, and reducing the sense of blockage during the battery insertion and removal process.

[0054] In one embodiment, please refer to Figure 8 , a slope 223 extending from the side wall 11 toward the side of the rigid member 22 facing away from the elastic member 21 is formed at the position of the rigid member 22 near the opening 13. When inserting the battery, the battery body 3 first abuts against the slopes 223 on both sides and slides along the guidance of the slopes 223 until it fits and abuts against the side surface of the rigid member 22. Through the guiding transition of the slopes 223, it can be avoided that the edge of the rigid member 22 and the battery body 3 interfere and block due to misalignment when inserting the battery, affecting the smoothness of the battery assembly process.

[0055] In one embodiment, the elastic member 21 is made of a rubber or silicone-based material, and the rigid member 22 is made of a plastic or metal material.

[0056] In one embodiment, the projections of the two battery limiting components 2 in the second direction Y overlap, and the length of the battery limiting component 2 in the first direction X is greater than the length in the third direction Z. The symmetrical arrangement of the battery limiting components 2 on both sides can ensure the stability of the clamping restraint on the battery body 3. At the same time, the battery limiting component 2 extending along the first direction X can make the support of the battery limiting component 2 on the battery body 3 more stable.

[0057] In one embodiment, a biped robot is provided, including the battery compartment of the robot in the foregoing solution.

[0058] In one embodiment, a robot is provided, including the battery compartment of the robot in the foregoing solution.

Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present application.
