DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0027] like Figure 2-Figure 8As shown, a battery installation structure includes a battery 1 and a battery compartment 3. At least two slide rails 2 are formed at the bottom of the battery 1 and are arranged opposite to each other. The side wall of the slide rail 2 has a protrusion 21 extending along the width direction of the slide rail 2. The protrusion 21 has an inclined guide surface 211. The battery compartment 3 includes at least a first locking block 51, a second locking block 52, and an elastic reset member 4. In this embodiment, the elastic reset member 4 abuts between the first locking block 51 and the second locking block 52. Of course, one elastic reset member 4 can also abut on the side of the first locking block 51 away from the second locking block 52, and the other elastic reset member 4 abuts on the side of the second locking block 52 away from the first locking block 51. There is no specific limitation. The first locking block 51 and the second locking block 52 respectively have a blocking portion 53, and the blocking portion 53 has an inclined action surface 531.

[0028] When the battery 1 is pushed into the battery compartment 3, the blocking portion 53 and the slide rail 2 move relative to each other. When they move to the point where the inclined guide surface 211 and the inclined action surface 531 abut against each other, under the mutual squeezing action of the inclined guide surface 211 and the inclined action surface 531, the first locking block 51 and the second locking block 52 move toward each other and squeeze the elastic reset member 4, so that the distance between the first locking block 51 and the second locking block 52 is reduced. After the protrusion 21 passes over the first locking block 51 and the second locking block 52, the first locking block 51 and the second locking block 52 are extended and reset under the action of the elastic reset member 4. At this time, the blocking portion 53 and the protrusion 21 abut against each other, and the blocking portion 53 can prevent the battery 1 from escaping from the battery compartment 3.

[0029] like Figure 5 , Figure 6 , Figure 7 As shown, in this embodiment, the slide rail 2 is a slide groove, and the protrusion 21 is located on the outer side wall of the slide groove close to the edge of the battery 1, that is, the protrusion 21 reduces the width of the slide rail 2. Figure 5 Taking the direction shown as an example, the inclined guide surface 211 of the protrusion 21 extends obliquely from bottom to top and from outside to inside, and the other side of the protrusion 21 is a horizontal plane. The lower end of the slide rail 2 is open, that is, the end of the slide rail 2 placed in the battery compartment 3 is open, and the open end 22 is flared, so that the blocking portion 53 can easily enter the slide rail 2 from the open end.

[0030] In this embodiment, the distance between the protrusion 21 and the other side wall of the slide rail 2 is approximately equal to the maximum width of the blocking portion 53, so that the protrusion 21 passes over the first locking block 51 and the second locking block 52, or the first locking block 51 and the second locking block 52 move toward each other to avoid the protrusion 21, making the structure more stable and effective.

[0031] Of course, in other embodiments, the slide rail 2 may also be a protruding rail structure, and a protrusion 21 is set on the outer wall of the slide rail 2. In this case, the protrusion 21 increases the width of the slide rail 2, and a groove structure is set in the battery compartment 3, that is, there is no restriction on the specific structure of the slide rail 2.

[0032] like Figure 4 As shown, in order to ensure that the first locking block 51 and the second locking block 52 can translate relative to each other and avoid offset, a limiting cavity 32 is formed in the battery compartment 3, and at least part of the first locking block 51 and the second locking block 52 are limitedly connected in the limiting cavity 32. In this embodiment, the first locking block 51 and the second locking block 52 fall into the limiting cavity 32 as a whole, and the periphery of the limiting cavity 32 is adapted to the partial shapes of the first locking block 51 and the second locking block 52.

[0033] In order to ensure the stability of the overall structural coordination, there are two elastic reset members 4, and a partition 321 is provided in the limiting cavity 32. The two elastic reset members 4 are located on the same axis, one end of one elastic reset member 4 abuts against one side of the partition 321, and the other end abuts against the first locking block 51, and one end of the other elastic reset member 4 abuts against the other side of the partition 321, and the other end abuts against the second locking block 52. In this embodiment, the first locking block 51 and the second locking block 52 have the same structure, and are symmetrically arranged on both sides of the partition 321, and the specific structures of the first locking block 51 and the second locking block 52 are not limited.

[0034] In order to facilitate pulling the battery 1 out of the battery compartment 3, an unlocking member 6 is also included, which has at least two inclined push surfaces 61, the first locking block 51 has an inclined sliding surface 54 that can be abutted against one of the inclined push surfaces 61, and the second locking block 52 has an inclined sliding surface 54 that can be abutted against the other inclined push surface 61.

[0035] In this embodiment, the inclined thrust surface 61 , the inclined sliding surface 54 , the inclined guiding surface 211 , and the inclined action surface 531 are all inclined in the same direction.

[0036] When external force is applied to the unlocking member 6, the inclined pushing surface 61 translates against the inclined sliding surface 54, so that the first locking block 51 and the second locking block 52 move toward each other and squeeze the elastic return member 4 until the blocking portion 53 passes over the protrusion 21 in the opposite direction. The reverse direction here refers to the direction in which the inclined guide surface 211 and the inclined action surface 531 slide against each other and the first locking block 51 and the second locking block 52 pass over the protrusion 21.

[0037] In order to ensure the translation of the unlocking member 6, at least part of the limit card of the unlocking member 6 is set in the limit cavity 32, that is, part of the side wall of the limit cavity 32 is against the outer walls on both sides of the unlocking member 6, limiting the deviation of the unlocking member 6 in other directions.

[0038] In order to facilitate the battery 1 to be separated from the battery compartment 3, an elastic pusher 31 is provided at the inner bottom of the battery compartment 3. When the battery 1 is completely placed in the battery compartment 3, the elastic pusher 31 abuts against the inner end surface of the battery 1, and the elastic pusher 31 is in a compressed state. Therefore, once the unlocking member 6 is activated, the first locking block 51 and the second locking block 52 are close to each other, so that the blocking portion 53 avoids the protrusion 21, and the elastic pusher 31 can immediately push the battery 1 out of the battery compartment 3, which makes the disassembly and assembly of the battery 1 more labor-saving.

[0039] like Figure 1 As shown, a quadruped robot includes a shell 7, a battery compartment 3 connected to the bottom of the shell 7, a front foot 82 and a rear foot 82 connected to the shell 7, and a battery 1, and the above-mentioned battery mounting structure is arranged between the battery 1 and the battery compartment 3.

[0040] The installation process of the battery 1 and the battery compartment 3 in the utility model is to place the open end 22 of the slide rail 2 of the battery 1 toward the opening of the battery compartment 3, so that the blocking parts 53 of the first locking block 51 and the second locking block 52 move in the two slide rails 2 respectively; when the inclined action surface 531 of the blocking part 53 abuts against the inclined guide surface 211 of the protrusion 21, under the interaction between the two, the first locking block 51 and the second locking block 52 are respectively pushed by the protrusion 21 to move in a direction close to each other and compress the elastic reset member 4 until the protrusion 21 passes over the first locking block 51 and the second locking block 52. At this time, under the action of the elastic reset member 4, the first locking block 51 and the second locking block 52 extend and reset, and the horizontal side surface of the protrusion 21 abuts against the horizontal side surface of the blocking part 53, and the protrusion 21 cannot reversely pass over the first locking block 51 and the second locking block 52 and detach from the battery compartment 3, so as to achieve a stable assembly of the battery 1 and the battery compartment 3. At the same time, the elastic push-out member 31 is compressed by the end surface of the battery 1.

[0041] The battery removal process is to push the unlocking piece 6 toward the inside of the battery compartment 3, and the two inclined pushing surfaces 61 act on the inclined sliding surface 54 of the first locking block 51 and the inclined sliding surface 54 of the second locking block 52 respectively, thereby driving the first locking block 51 and the second locking block 52 to move in a direction close to each other, so that the two blocking portions 53 pass over the two protrusions 21 in the opposite direction, and under the thrust of the elastic pushing piece 31, the battery 1 can be smoothly pulled out of the battery compartment 3.

[0042] The above specific implementation modes are used to explain the present invention rather than to limit the present invention. Any modification and change made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
