Description

Technical Field

[0001] This utility model belongs to the field of humanoid robot technology, and in particular relates to a battery disassembly and assembly structure and robot. Background Technology

[0002] When the humanoid robot's battery is depleted, it needs to be recharged or replaced, at which point the battery needs to be removed from the humanoid robot.

[0003] Chinese patent CN112223347A discloses a "Battery Installation Structure and Robot," which describes the battery pack installation and fixing process as follows: The battery pack is placed above a fixed frame, ensuring that the locking groove on the battery pack and the locking element on the fixed frame are aligned vertically. The battery pack is then moved (lowered) closer to the fixed frame until the locking element contacts the vertical surface of the battery pack (the surface with the locking groove located on this surface), and the battery pack continues to descend. During this descent, the battery pack's gravity exerts a rotational force on the locking element, causing it to rotate relative to the fixed frame away from the battery pack. At this point, the elastic element deforms under stress. The battery pack continues to descend until the locking element on the fixed frame is directly aligned with the locking groove. The elastic element then returns to its original shape and rotates the locking element relative to the fixed frame closer to the battery pack, causing the locking element to engage with the locking groove. This structure is relatively complex, and if the installation direction is changed, the gravity of the battery pack will no longer exert force on the locking element. Furthermore, the elastic element is prone to failure after repeated battery insertion and removal. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a battery disassembly and assembly structure and robot, which can extend and retract the locking tongue by rotating the operating handle, and can effectively maintain the state of the locking tongue. The structure is simplified and the operation is convenient.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a battery disassembly and assembly structure, comprising:

[0006] case;

[0007] The operating handle is rotatably connected to the housing via a pivot.

[0008] A locking tongue is telescopically connected to the housing, and has a protrusion on at least one side;

[0009] An elastic element, which abuts against the latch, is used to provide an elastic force to drive the latch out of the housing;

[0010] A limiting member, connected to the rotating shaft, can rotate synchronously with the rotating shaft. It has a slot for the protrusion to enter and exit. When the latch is in the extended housing state and / or in the retracted housing state, the opening of the slot is deviated from the direction of the latch's movement, so that the limiting member keeps the latch in its current state.

[0011] Furthermore, it also includes a reset component, which is connected to the rotating shaft and is used to drive the rotating shaft to rotate in the direction in which the latch extends out of the housing, and one end of which abuts against the limiting component.

[0012] Furthermore, the reset element is a torsion spring; a notch is formed on the side of the housing, the notch having a first blocking surface and a second blocking surface that can abut against the operating handle.

[0013] Furthermore, the limiting member includes a body, a protrusion extending from a first side of the body, and a bent portion extending from a second side of the body. The body forms a through hole for the rotating shaft to pass through. The protrusion, the body, and the bent portion surround and form a slot and a movable groove communicating with the slot. The width of the movable groove is greater than the width of the slot.

[0014] Furthermore, when the latch is in the extended housing state, the opening of the slot is perpendicular to the direction of movement of the latch, and the protrusion abuts against the projection.

[0015] Furthermore, a limiting concave surface is formed at the corner of the inner wall of the bent portion. When the latch is in the retracted housing state, the opening of the slot is parallel to the movement direction of the latch, and the protrusion falls into the limiting concave surface.

[0016] Furthermore, dampers are provided at both ends of the rotating shaft.

[0017] Furthermore, the rotation angle of the operating handle is 0-95 degrees.

[0018] This utility model also discloses a robot, including a torso, a battery, and the aforementioned battery disassembly and assembly structure.

[0019] Furthermore, battery disassembly and assembly structures are provided on both sides of the battery.

[0020] The beneficial effects of this utility model are as follows: the limiting component can keep the locking tongue in either the extended or retracted state of the housing, effectively preventing the locking tongue from switching between the two states arbitrarily during accidental operation. The structure is simple and effective. The limiting component rotates together with the rotating shaft, which is driven by the operating handle, making operation simple. The elastic component and the reset component work together to drive the locking tongue out of the housing, ensuring that the locking tongue is securely and effectively locked to the robot body. When installing the battery to the robot body, when the operating handle is rotated to the point where the locking tongue retracts into the housing, the operating handle acts as a handle for lifting the battery, making operation convenient and in line with user operating habits.

Detailed Implementation

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0037] like Figures 1-10 As shown, a battery disassembly and assembly structure includes a hollow housing 1, an operating handle 2 rotatably connected to the housing 1 via a pivot 3, a locking tongue 4 retractably connected to the housing 1, an elastic member 5 abutting against the locking tongue 4, and a limiting member 6 connected to the pivot 3.

[0038] The latch 4 is located inside the housing 1, and at least one side of this part is provided with a protrusion 41. The limiting member 6 can rotate synchronously with the rotating shaft 3, and the limiting member 6 has a groove 61 for the protrusion 41 to extend or enter. The elastic member 5 is used to provide the elastic force to drive the latch 4 to extend out of the housing 1. When the latch 4 is in the extended state of the housing 1, the opening of the groove 61 is deviated from the direction of movement of the latch 4, so as to prevent the latch 4 from easily retracting into the housing 1 when accidentally touched by external force; or, when the latch 4 is in the retracted state of the housing 1, the opening of the groove 61 is deviated from the direction of movement of the latch 4, so as to keep the latch 4 in the retracted state of the housing 1 and prevent it from easily extending out of the housing 1; or, whether the latch is in the extended state of the housing 1 or the retracted state of the housing 1, the opening of the groove 61 is deviated from the direction of movement of the latch 4, so as to keep the latch 4 in this state and prevent the latch 4 from switching between the two states at will.

[0039] like Figure 1 , Figure 2As shown, the housing 1 is relatively closed, with a through hole 11 on one side for the latch 4 to enter and exit. Two sides of the housing 1 perpendicular to the side containing the through hole 11 form notches 12 for accommodating the operating handle 2. The operating handle 2 is U-shaped, with its open ends rotatably connected to the notches 12. The notches 12 have a first blocking surface 121 and a second blocking surface 122. When the operating handle 2 rotates to abut against the first blocking surface 121, the latch 4 is extended out of the housing 1; when the operating handle 2 rotates to abut against the second blocking surface 122, the latch 4 is retracted into the housing 1. In this embodiment, the rotation angle of the operating handle 2 is 0-95 degrees, preferably a maximum rotation angle of 90 degrees, at which point the first blocking surface 121 and the second blocking surface 122 are perpendicular. The rotating shaft 3 is located inside the housing 1, with both ends extending from the side of the housing 1 and connected to the open ends of the operating handle 2.

[0040] When an external force is applied to rotate the operating handle 2, the rotating shaft 3 rotates accordingly, which in turn drives the limiting member 6 to rotate as well. The protrusion 41 in the slot 61 moves the locking tongue 4 relative to the housing 1, thereby extending or retracting the locking tongue 4. At the same time, the limiting member 6 can keep the locking tongue 4 in the extended or retracted state. In other words, the extension or retraction of the locking tongue 4 can be achieved by rotating the operating handle 2, and it can be kept in the correct state. The operation is simple, and the state of the locking tongue 4 can be intuitively judged by the relative position of the operating handle 2.

[0041] A reset member 7 is connected to the rotating shaft 3. The reset member 7 is used to drive the rotating shaft 3 to rotate in the direction of the locking tongue 4 extending out of the housing 1. In this embodiment, the reset member 7 is a torsion spring, the middle part of which is sleeved on the rotating shaft 3. One of its open ends abuts or is connected to the limiting member 6, and its other open end abuts directly or indirectly with the housing 1.

[0042] In this embodiment, to achieve balanced force distribution, protrusions 41 are provided on both sides of the locking tongue 4, and correspondingly, there are two limiting members 6 and two resetting members 7. Figure 4 As shown, the elastic element 5 is a spring, with one end abutting inside the housing 1 and the other end abutting against the locking tongue 4. In this embodiment, the number of elastic elements 5 can also be two.

[0043] like Figure 3 , Figure 8 , Figure 11 As shown, the limiting member 6 includes a body 62, a protrusion 63 extending from a first side of the body 62, and a bent portion 64 extending from a second side of the body 62, with the first side and the second side being opposite sides. The body 62 forms a through hole 621 for the rotating shaft 3 to pass through. The protrusion 63, the body 62, and the bent portion 64 surround and form a slot 61 and a movable groove 65 communicating with the slot 61. The width of the movable groove 65 is greater than the width of the slot 61.

[0044] by Figure 11 Taking the indicated direction as an example, the lower left side of the main body 62 protrudes downward to form a protrusion 63. This protrusion 63 is relatively small. The lower right side of the main body 62 has an L-shaped bend 64, which extends towards the side where the protrusion 63 is located, until it is directly opposite the protrusion 63. The slot 61 is the part formed by the protrusion 63 and the bend 64 directly opposite each other, while the movable groove 65 is the inner part of the slot 61. A limiting concave surface 66 is formed within the movable groove 65 at the corner of the inner wall of the bend 64. Figure 3 , Figure 8 As shown, the limiting concave surface 66 increases the width of part of the movable groove 65. When the protrusion 41 falls into the limiting concave surface 66, the protrusion 41 will not easily break through the inflection point 67 and leave the limiting concave surface 66 because there is an inflection point 67 between the limiting concave surface 66 and the side wall of the bent part 64.

[0045] like Figures 2-5 As shown, when the latch 4 is in the extended position of the housing 1, the limiting member 6 moves to a specific position with the rotating shaft 3. Specifically, the opening of the slot 61 is perpendicular to the direction of movement of the latch 4, and the protrusion 41 abuts against the protrusion 63. Figure 3 Taking the direction shown as an example, the movement direction of the locking tongue 4 is left and right, the opening of the slot 61 faces downward, and the protrusion 41 abuts against the protrusion 63 on the left. Under the elastic force of the reset member 7 and the elastic member 5, the locking tongue 4 remains in the state of extending out of the housing 1, and the limiting member 6 also remains in the state of the slot 61 opening facing downward. At this time, the movement trend of the locking tongue 4 is to retract to the left into the housing 1. The downward opening of the slot 61 is deviated from the movement trend of the locking tongue 4. Therefore, when the locking tongue 4 is accidentally touched by external force, the protrusion 41 is blocked by the protrusion 63, and the reset member 7 is in a natural extended state to apply external force to the limiting member 6. The protrusion 41 will not move to the left, that is, the locking tongue 4 will not move to the left to retract into the housing 1.

[0046] like Figures 7-10 As shown, when an external force is applied to rotate the operating handle 2, causing the latch 4 to be in the retracted housing 1 state, the limiting member 6 moves to a specific position along with the rotating shaft 3. Specifically, the opening of the slot 61 is parallel to the direction of movement of the latch 4, and the protrusion 41 falls into the limiting concave surface 66. Figure 8Taking the direction shown as an example, the movement direction of the latch 4 is left and right, and the opening of the slot 61 faces left. Specifically, when the latch 4 retracts into the housing 1 to the left, the opening of the slot 61 faces left. Since an external force is continuously applied to the operating handle 2, the limiting member 6 remains in the state where the opening of the slot 61 faces left. At this time, the movement trend of the latch 4 is to extend into the housing 1 to the right. The opening of the slot 61 faces left, which is opposite to the movement trend of the latch 4. Thus, the limiting member 6 restricts the latch 4 from moving to the right and extending out of the housing 1. Moreover, due to the setting of the inflection point 67, even if the external force causes a malfunction to the operating handle 2, when the external force does not reach a certain strength, it is impossible to make the protrusion 41 cross the inflection point 67 and disengage from the limiting concave surface 66. In other words, the limiting member 6 cannot easily rotate in the opposite direction to make the protrusion 41 cross the inflection point 67 and disengage from the limiting concave surface 66, ensuring that the latch 4 remains stably in the state of retracting into the housing 1.

[0047] To prevent the operating handle 2 from being rotated too fast and pinching the operator's fingers, dampers 8 are provided at both ends of the rotating shaft 3. The damper 8 is a structure in the prior art and will not be described in detail. The damper 8 can slow down the rotation speed of the rotating shaft 3.

[0048] A robot includes a torso (not shown), a battery 9, and the aforementioned battery mounting / removing structure. The battery 9 is detachably mounted on the torso via the battery mounting / removing structure. Figures 12-14 As shown, battery 9 has battery removal and installation structures on both sides, and the locking tongue 4 is set outwards.

[0049] When it is necessary to install the battery 9 into the robot body, rotate the operating handle 2 upward until it abuts against the second blocking surface 122, so that the locking tongue 4 retracts into the housing 1. The operating handle 2 then acts as a handle to lift the battery 9. After the battery 9 is installed into the body, apply external force to rotate both operating handles 2 downward until they abut against the first blocking surface 121. The locking tongue 4 remains in the extended position of the housing 1, thereby achieving mutual locking between the locking tongue 4 and the locking groove of the robot body.

[0050] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
