[0002] Four -legged robot, also called leg-foot type robot, is a kind of robot that imitates the leg movement of human or animal. For the dismounting of four -legged robot, Chinese patent CN219575835U discloses "battery pack structure and robot", which sets a clamping assembly on the inner wall of the battery box. When unlocking, the user moves the clamping block inward by turning the protrusion on the clamping block, so that the clamping block is retracted into the battery box through the first through hole. At this time, the clamping block is released from the clamping action with the robot, and the battery pack is quickly unlocked. At this time, the battery pack can be taken out from the robot. When locking, the battery pack is placed in the robot, and the clamping block moves outward under the elastic force of the elastic member and extends to the outside of the battery box through the first through hole. At this time, the clamping block is clamped with the robot, and the battery pack is quickly locked. According to the analysis, when the battery needs to be dismounted, the user needs to use one hand to move the clamping blocks on both sides to the middle, and then use the other hand to assist to take out the battery from the robot. However, the disadvantages of this battery dismounting method are also obvious, that is, both hands need to be operated, and both hands need to operate the battery at the same time.

[0030] In order to enable personnel in the technical field to better understand the scheme of the utility model, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the utility model.

[0031] As shown in FIG. Figures 1-7 A battery dismounting structure for a quadruped robot, comprising telescopic assemblies 1 arranged on both sides of a battery 2, an unlocking member 3, and a locking portion (not shown in the figure) arranged on a quadruped robot 5, the locking portion is arranged in correspondence with the telescopic assemblies 1. In this embodiment, the number of telescopic assemblies 1 is two, and similarly, the number of locking portions is also two.

[0032] The single telescopic assembly 1 comprises a telescopic buckle 11 and an elastic member 12 abutting against the telescopic buckle 11, specifically, the locking portion is arranged in correspondence with the telescopic buckle 11, and the unlocking member 3 is connected to the telescopic buckle 11 of the two telescopic assemblies 1 on both sides, and the unlocking member 3 can be deformed under the action of an external force, so as to exert an external force to pull the unlocking member 3, and the telescopic buckles 11 on both sides are synchronously moved to be separated from the locking portion, so as to disassemble the battery 2 from the quadruped robot 5. In this embodiment, the unlocking member 3 can be made of elastic rubber or the like.

[0033] Specifically, the telescopic buckle 11 can be translated along the first direction to achieve the purpose of entering or leaving the locking part, and the battery 2 can be translated along the second direction to achieve the purpose of dismounting or mounting the quadruped robot 5, when the external force is applied to pull the unlocking part 3, the telescopic buckle 11 is translated along the first direction to leave the locking part in the first time period, and the battery 2 is translated along the second direction to move away from the quadruped robot 5 in the second time period, the first time period and the second time period are continuous, in other words, the second time period follows the first time period without pause after the end of the first time period, or the first time period and the second time period at least partially overlap, in other words, the second time period has started when the first time period has not ended.

[0034] The utility model discloses the characteristics of the deformable unlocking part 3 under the action of external force, and simultaneously connects two telescopic buckles 11 at two ends of an unlocking part 3, so that when the operator performs a pulling action with one hand, specifically when the external force is applied to pull the unlocking part 3 away from the quadruped robot 5, the telescopic buckles 11 on both sides can be translated in the direction of approaching each other, and the telescopic buckles 11 on both sides are synchronously moved to leave the locking part, so that the battery 2 can be quickly separated from the battery compartment of the quadruped robot 5, and the operation does not need to be performed with both hands, and no matter how large the volume of the battery 2 is, one-handed operation can be realized.

[0035] In the embodiment, the first direction and the second direction are perpendicular, and specifically, as shown in Figure 1 The first direction is the width direction of the battery, and the second direction is the longitudinal direction of the battery,

[0036] As shown in Figures 4-7 The telescopic buckle 11 comprises a connecting part 111, a locking part 112 and a mounting part 113, the connecting part 111, the locking part 112 and the mounting part 113 are integrally arranged, and the three are close to the same plane, the locking part 112 forms a cutting surface 114 with reduced width, the cutting surface 114 extends obliquely from the locking part to the battery 2 and from the outside to the inside, here, the side of the battery 2 close to the outside of the quadruped robot 5 is defined as the outside, for example, the cutting surface 114 extends obliquely from left to right and from bottom to top as shown in the direction. Figure 7 When the battery 2 is inserted into the battery compartment of the quadruped robot 5, the cutting surface 114 can slide against the quadruped robot 5, so that the telescopic buckle 11 is gradually retracted to the inside of the battery 2.

[0037] The mounting portion 113 has a positioning groove 116 into which a part of the elastic member 12 extends, and an extension wall 117 extending along the extension and retraction direction of the elastic member 12, the end of the elastic member 12 is inserted into the positioning groove 116, the positioning groove 116 can position the mounting of the elastic member 12, avoiding the elastic member 12 from falling off, and the extension wall 117 positions the elastic member 12 in the length direction of the elastic member 12, avoiding the elastic member 12 from deviating.

[0038] The side of the battery 2 facing outward has an end cover 21, the end cover 21 is provided with a shielding portion 211, the shielding portion 211 is at the corresponding position of the unlocking piece 3, the shielding portion 211 is used to shield the structure of the components inside the end cover 21, so that the appearance of the end cover is more simple. The outer side surface of the extension arm 117 can abut against the inner side surface of the shielding portion 211, so that the extension wall 117 slides against the inner side surface of the shielding portion 211, ensuring the translation of the telescopic buckle 11, avoiding the sliding track of the telescopic buckle 11 from deviating.

[0039] The end cover 21 forms a limiting cavity 212 for clamping the elastic member 12, so that one end of the elastic member 12 abuts against the inner bottom surface of the positioning groove 116, and the other end abuts against the end surface of the limiting cavity 212. The end cover 21 is also formed with a notch groove 213 and a through hole 214 for the telescopic buckle 11 to pass out, and the through hole 214 is arranged corresponding to the locking portion 4, that is, the through hole 214 is located at the side position of the battery 2 adhering to the quadruped robot 5. Specifically, the locking portion 4 can be a slot hole structure with an opening opposite to the through hole 214, as long as it can prevent the telescopic buckle 11 from separating from the quadruped robot 5 in the longitudinal direction of the battery 2, and the specific structure is not limited.

[0040] The notch groove 213 refers to the hollow part between the end surface of the shielding portion 211 and the side wall of the through hole 214 on the end cover 21, in other words, one side wall of the notch groove 213 is formed by the end surface of the shielding portion 211, the unlocking piece 3 is connected with the telescopic buckle 11 at the notch groove 213, so that the bent portion 31 and the fastener 6 move in the notch groove 213, the notch groove 213 limits the movement stroke of the telescopic buckle 11, avoiding the telescopic buckle 11 from moving too much to the inside of the battery 2, and also avoiding the unlocking key 3 from deforming too much under external force.

[0041] The locking portion 112 has a clamping step 115, which can abut against the side wall of the through hole 214, thereby preventing the telescopic buckle 11 from moving too much to the outside of the battery 2 and causing it to separate from the battery 2. As Figure 6 shown, the distance L1 between the end surface of the shielding portion 211 and the end surface of the bent portion 31 needs to be less than the length L2 between the end of the telescopic buckle 11 and the clamping step 115, that is, L1 < L2, so as to ensure that the telescopic buckle 11 will not separate from the notch groove 213 during translation.

[0042] As Figures 1-3As shown, the outer side of the end cover 21 is formed with an inner concave surface 215 corresponding at least partially to the position of the unlocking member 3, where the inner concave surface 215 refers to being inwardly recessed relative to the vertical plane corresponding to the unlocking member 3, and the width of the inner concave surface 215 is greater than or equal to the width of the unlocking member 3, so as to form a pulling gap 7 between the inner concave surface 215 and the inner side of the unlocking member 3, through which the operator can stretch his hand to pull the unlocking member 3 outwardly.

[0043] The unlocking member 3 is flat, when the battery 2 is locked in the quadruped robot 5, the unlocking member 3 is not pulled by external force, and the unlocking member 3 is parallelly accommodated in the inner concave surface 215, where parallel refers to being parallel to the first direction, that is, the unlocking member 3 is stretched to a flat state under the pulling of the two-sided telescopic buckles 11, so that the unlocking member 3 does not protrude from the surface of the end cover 21, and the overall structure is more simple.

[0044] For the fixed assembly of the unlocking member 3 and the battery 2, as shown, Figures 5-7 The unlocking member 3 is connected to the connecting portion 111 through the fastener 6, specifically, the end of the unlocking member 3 is formed with a bending portion 31, the fastener 6 includes a first fastening body 61 and a second fastening body 62, the first fastening body 61 passes through the connecting portion 111 and the bending portion 31 and is connected to the second fastening body 62, so that the connecting portion 111 and the second fastening body 62 clasp the bending portion 31, and the pulling gap 7 is formed between the battery 2 and the unlocking member 3. The pulling gap 7 is located between the inner side of the unlocking member 3 and the outer side of the shielding portion 211, and the thickness of the second fastening body 62 also contributes to the pulling gap 7, so as to provide sufficient space for the operator to stretch his hand into the pulling gap 7 to pull the unlocking member 3 outwardly.

[0045] When it is necessary to disassemble the battery 2 from the quadruped robot 5, an external force is applied to pull the unlocking member 3 outwardly, specifically, the operator can pull the unlocking member 3 at the middle region thereof with one hand, the unlocking member 3 has elasticity and can be deformed, the deformation causes the middle of the unlocking member 3 to protrude outwardly, and the two sides of the unlocking member 3 move toward each other, thereby driving the two telescopic buckles 11 to move toward each other in a synchronous manner, that is, the two telescopic buckles 11 are synchronously translated along the first direction to approach each other, once the telescopic buckles 11 completely disengage from the locking portion, or in other words, the telescopic buckles 11 approach the completely disengaged state, under the pulling action of the unlocking member 3, the battery 2 as a whole moves in a direction away from the quadruped robot 5, that is, the battery 2 with the telescopic assembly 1 as a whole is translated along the second direction, so that the battery 2 can quickly disengage from the quadruped robot 5, and the whole action is fast and smooth without the need for the operator to change actions.

[0046] When the battery 2 needs to be installed into the battery compartment of the quadruped robot 5, the unlocking piece 3 can also be used to lift the battery 2, at this time not only the battery 2 is lifted, but also the two sides of the telescopic buckle 11 are retracted to the inside of the battery 2 under the pulling of the unlocking piece 3, that is, one action realizes the transfer of the battery 2 and the inward pulling of the telescopic buckle 11, so as to facilitate the placement of the battery 2 into the battery compartment of the quadruped robot 5.

[0047] The above specific embodiments are used to explain and illustrate the present application, rather than limit the present application, and any modification and change made to the present application within the spirit and protection scope of the claims of the present application all fall into the protection scope of the present application.
