Description

Technical Field

[0002] The development of industrial automation and mechanization has led to the widespread application of robots in people's social lives and production, where they can replace or assist people in their work. Robots require batteries for power during operation, and due to limited battery capacity, batteries need to be replaced frequently or maintained periodically during the robot's service life.

[0003] Traditional bolt-fixed battery compartments rely on manual disassembly, which is inefficient and difficult to adapt to the needs of unmanned operation and maintenance. Existing quick-change battery structures are usually spring-loaded clip structures that rely on elastic deformation for locking. With long-term use, these are prone to locking failure due to metal fatigue, posing a risk of poor battery contact and reducing the reliability and safety of the robot. Utility Model Content

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0032] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Please refer to Figure 1 and Figure 2 This embodiment provides a quick-change battery structure 100, including a battery compartment 110 and a battery 120. The battery compartment 110 has an opening for removing or installing the battery 120, and the inner wall of the opening is provided with a slot 111. The side of the battery 120 exposed in the opening is provided with a locking part, which includes a rotation drive 122 and a drive-connected locking plate 121. When the battery 120 is installed in the battery compartment 110, the rotation drive 122 can be driven to rotate so as to drive the locking plate 121 to insert or exit the slot 111.

[0034] Specifically, such as Figure 1 and Figure 2 As shown, when the quick-change battery structure 100 is applied to a robot, the battery compartment 110 can be installed inside the robot body, and the battery 120 is used to power the robot.

[0035] The battery compartment 110 has an opening that communicates with the outside. The battery 120 can be detachably installed in the battery compartment 110 through the opening. When the battery 120 is installed in the battery compartment 110 through the opening, it can be fixed together with the battery compartment 110 and form an electrical connection.

[0036] To ensure the stability of the connection between battery 120 and battery compartment 110, such as Figure 2 As shown, a retaining plate 121 is also provided on the outer wall surface of the battery 120. Correspondingly, a retaining groove 111 is provided at the opening of the battery compartment 110. The retaining plate 121 can be engaged in the retaining groove 111 by the rotation drive member 122, so that the battery 120 is fixedly connected to the battery compartment 110. When it is necessary to remove the battery 120, the retaining plate 121 can be moved away from the retaining groove 111 by the rotation drive member 122 to separate the retaining plate 121 from the retaining groove 111.

[0037] Preferably, the card slot 111 is formed on the inner wall of the battery compartment 110 along the opening side edge of the battery compartment 110.

[0038] It should be noted that, in one possible implementation of this application, such as Figure 4 As shown, in order to further enhance the stability of the battery 120 during disassembly or installation, at least one inner wall of the battery compartment 110 is provided with at least one guide 112, the extension direction of the guide 112 being in the same direction as the disassembly or installation direction of the battery 120.

[0039] Specifically, the guide member 112 serves to guide the installation and removal of the battery 120. In one specific embodiment of this application, the guide member 112 includes a guide rail and rollers slidably disposed on the guide rail; the guide rail is disposed on the inner wall of the battery compartment 110 along the disassembly or installation direction of the battery 120, and the rolling surface of the rollers can roll into contact with the outer wall of the battery 120. Therefore, during the installation and removal of the battery 120, the cooperation between the rollers and the guide rail can improve the efficiency of the installation and removal of the battery 120, while ensuring the accuracy of the installation position of the battery 120.

[0040] Preferably, there are multiple guide members 112, each located on at least two sides of the battery 120, to ensure uniform force distribution on the battery 120 during assembly and disassembly, further improving the accuracy and stability of the assembly and disassembly process. Figure 4 As shown, the battery compartment 110 has guide members 112 on three inner walls, and two guide members 112 are spaced apart on each side.

[0041] like Figure 5 As shown, in addition to placing the guide 112 on the inner wall of the battery compartment 110, the guide 112 can also be placed on the outer wall of the battery 120, as long as the guide 112 can guide the battery 120. This application does not impose any restrictions on the specific location or number of guides 112, as long as the stability and accuracy of the battery 120 assembly and disassembly process can be guaranteed.

[0042] In one possible implementation of this application, such as Figure 5 and Figure 7 As shown, a quick-release connector 123 is provided on the side of the battery 120 facing away from the opening, and a mating connector 113 is provided on the inner wall of the battery compartment 110 accordingly; when the battery 120 is installed in the battery compartment 110, the quick-release connector 123 and the mating connector 113 are electrically connected.

[0043] The quick-release connector 123 and the mating connector 113 enable quick assembly and disassembly of the battery compartment 110 and the battery 120. By setting up the quick-release connector 123 and the mating connector 113, the connection and separation operation between the battery 120 and the battery compartment 110 can be completed in a short time, avoiding the cumbersome steps required by the traditional complex connection method and improving the efficiency of battery 120 replacement.

[0044] In one possible implementation of this application, such as Figure 6 As shown, a positioning pin 124 is provided on the side of the battery 120 facing the opening, and a positioning hole is correspondingly provided on the inner wall of the battery compartment 110, into which the positioning pin 124 can be inserted. The cooperation between the positioning pin 124 and the positioning hole can improve the installation accuracy of the battery 120, enabling the battery 120 to be quickly and accurately installed in the correct installation position in the battery compartment 110, avoiding problems such as poor electrical connection and mechanical damage caused by installation position deviation.

[0045] In one possible implementation of this application, such as Figure 5 As shown, in order to further improve the disassembly efficiency of battery 120, the bottom surface of battery compartment 110 is also provided with ejection assembly 130 (the bottom surface is the side opposite to the opening of battery compartment 110); ejection assembly 130 includes elastic element. When battery 120 is installed in battery compartment 110, elastic element is subjected to force and stores energy; when battery 120 is disassembled, after the card plate 121 separates from the card slot 111, as its resistance to elastic element gradually decreases, the elastic element releases energy to quickly eject battery 120 from the opening of battery compartment 110, which also makes it easier to disassemble battery 120.

[0046] The aforementioned quick-swap battery structure 100 uses a rotary drive component 122 to mechanically control the rigid engagement of the locking plate 121 and the slot 111, avoiding the weakening of locking force due to long-term use. Under the condition of no external force, the locking plate 121 will not disengage from the slot 111, significantly improving the locking reliability of the battery 120. Furthermore, the operation process is simple, and the operator can insert or remove the locking plate 121 simply by rotating it, further improving the battery swapping efficiency and enhancing the reliability and safety of the robot.

[0047] In one possible implementation of this application, such as Figure 3As shown, the rotary drive 122 includes a crank 1221 and a connecting rod 1222. One end of the connecting rod 1222 is connected to the clamping plate 121, and the other end is hinged to the crank 1221. When the clamping plate 121 is fully inserted into the clamping slot 111, the axis of the connecting rod 1222 passes through the rotation center of the crank 1221.

[0048] Specifically, such as Figure 3 As shown, crank 1221 is a rod that can rotate about a fixed axis, while connecting rod 1222 can transmit force to locking plate 121. In the rotation drive 122 of this locking part, crank 1221 and connecting rod 1222 cooperate with each other to convert the rotational motion of crank 1221 into linear motion of locking plate 121.

[0049] Since the crank 1221 is hinged to the connecting rod 1222, the axis of the connecting rod 1222 passes through the rotation center of the crank 1221 and the locking part is located at the dead point only when the locking plate 121 is fully inserted into the slot 111. Therefore, the locking plate 121 will not be accidentally removed from the slot 111 due to abnormal disassembly or assembly, thus avoiding the possibility of the battery 120 accidentally falling out of the battery compartment 110.

[0050] Furthermore, when the card plate 121 is inserted into the card slot 111, the card plate 121 and the inner wall of the card slot 111 have a preset distance along the first direction a, where the first direction a is the width direction of the card slot 111.

[0051] Specifically, in order to ensure that the connecting rod 1222 can drive the locking plate 121 to move together when driven, the locking plate 121 is inserted into the locking slot 111 and has a preset distance from the inner wall of the locking slot 111 along the first direction a. This distance provides a certain amount of room for the locking plate 121 to move when subjected to other external forces. In other words, the setting of this preset distance avoids the inner wall of the locking slot 111 from being located on the movement path of the locking plate 121, thereby avoiding the jamming phenomenon caused by the locking plate 121 being too tightly attached to the inner wall of the locking slot 111, and ensuring that the locking plate 121 can be smoothly dislodged from the locking slot 111 when it is necessary to separate the locking plate 121.

[0052] Among them, such as Figure 3 As shown, the number of connecting rods 1222 can be one or two. When there are two connecting rods 1222, the two connecting rods 1222 are respectively arranged on opposite sides of the crank 1221; the slots 111 are correspondingly arranged with the connecting rods 1222. When there are two connecting rods 1222, the number of locking plates 121 and slots 111 are also two each. The two slots 111 can be arranged opposite each other to further improve the connection stability between the battery compartment 110 and the battery 120.

[0053] Optionally, such as Figure 8As shown, in order to further improve the connection stability between the battery compartment 110 and the battery 120, the side of the battery 120 with the locking part also has an assembly part 126. The assembly part 126 is located on the edge of the battery 120 near the slot 111. The assembly part 126 has a cavity that communicates with the outside. The card plate 121 is at least partially disposed in the cavity and can move relative to the cavity. A spring 1261 is provided at the bottom of the cavity. The spring 1261 can abut against the side of the card plate 121 facing the rotation drive member 122.

[0054] Specifically, the number of assembly parts 126 can be one or two, preferably, such as Figure 8 As shown, there are two assembly parts 126, which are respectively disposed on the left and right sides of the retaining plate 121. Each assembly part 126 has a cavity, the bottom of which is perpendicular to the surface of the battery 120, for mounting a spring 1261. To ensure that the retaining plate 121 can abut against the spring 1261, an opening is provided around the periphery of the assembly part 126, which communicates with the cavity. The retaining plate 121 can extend into the cavity of the assembly part 126 through the opening, so that one end of the spring 1261 abuts against the edge of the retaining plate 121 and the other end abuts against the bottom of the cavity.

[0055] When the battery 120 is installed into the battery compartment 110, the crank 1221 is first driven to rotate, so that the connecting rod 1222 drives the clamping plate 121 to move into the cavity of the assembly part 126, thereby ensuring that the battery 120 can be fully installed into the battery compartment 110, and avoiding the battery 120 from not being fully pushed into the battery compartment 110 due to the protruding clamping plate 121 abutting against the side wall of the battery compartment 110. At this time, the clamping plate 121 compresses the spring 1261, and the spring 1261 stores energy under force.

[0056] When the battery 120 is fully pushed into the battery compartment 110, the locking plate 121 is aligned with the locking slot 111 of the battery compartment 110. The crank 1221 is driven to rotate in the opposite direction again, so that the locking plate 121 is driven to extend out of the cavity of the assembly part 126 through the connecting rod 1222. At this time, the spring 1261 releases energy to drive the locking plate 121 to quickly lock into the locking slot 111, and at the same time, the connecting rod 1222 and the crank 1221 are driven to quickly reset. At this time, the axis of the connecting rod 1222 passes through the rotation center of the crank 1221, and the locking part is located at the dead point position. The locking plate 121 will not be accidentally removed from the locking slot 111 due to abnormal disassembly or assembly.

[0057] Optionally, the rotary drive 122 also includes a handle 1223, which is connected to the crank 1221. The handle 1223 can drive the crank 1221 to move the connecting rod 1222 and the clamping plate 121.

[0058] Specifically, in one embodiment of this application, such as Figure 3As shown, the handle 1223 has an arc-shaped structure for easy gripping by the operator. The two ends of the handle 1223 are connected to the crank 1221, allowing the crank 1221 to drive the connecting rod 1222 and the locking plate 121 to rotate. Alternatively, the handle 1223 can also be a columnar structure protruding from the middle of the crank 1221. This columnar structure facilitates the operator's grip on the handle 1223 and allows them to rotate the crank 1221. It should be noted that this application does not impose any restrictions on the specific form of the handle 1223, as long as it allows the operator to reliably rotate the crank 1221 using the handle 1223.

[0059] The handle 1223 makes the operation of the rotary drive 122 more user-friendly and convenient. The operator can drive the crank 1221 to rotate clockwise or counterclockwise using the handle 1223, causing the locking plate 121 to insert into or retract from the locking slot 111. For example, when the crank 1221 rotates clockwise, it can disengage the locking plate 121 from the locking slot 111 via the connecting rod 1222; when the crank 1221 rotates counterclockwise, it can re-insert the locking plate 111 into the locking slot 111.

[0060] Furthermore, such as Figure 8 As shown, a torsion spring 125 is provided at the connection between the handle 1223 and the crank 1221. One end of the torsion spring 125 abuts against the crank 1221 and the other end abuts against the handle 1223, which is used to provide a restoring force to the handle 1223.

[0061] like Figure 3 As shown in one specific embodiment of this application, the opposite ends of the handle 1223 are respectively connected to the crank 1221. When the battery 120 is fixed in the battery compartment 110, the handle 1223 can fit against the surface of the battery 120 to improve space utilization. When the battery 120 needs to be removed from the battery compartment 110, the handle 1223 can be rotated to be perpendicular to the surface of the battery 120, so that the operator can easily hold the handle 1223 to perform the subsequent quick battery replacement operation. During the rotation of the handle 1223, the torsion spring 125 is compressed and stores energy. When the operator stops rotating the handle 1223, the torsion spring 125 releases energy to drive the handle 1223 to return to its original position, further improving the ease of operation of the quick battery replacement structure 100.

[0062] In another aspect, this application provides a robot including a body and a quick-change battery structure 100, the quick-change battery structure 100 being disposed within the body. The specific structure and beneficial effects of the quick-change battery structure 100 have been described in detail above and will not be repeated here. By incorporating the quick-change battery structure 100, the robot simplifies the battery swapping process and improves the robot's reliability and safety.

[0063] In one possible embodiment of this application, the robot further includes a limit switch disposed in a slot 111 of the quick-change battery structure 100, and the height of the limit switch is less than the depth of the slot 111. When the card plate 121 is inserted into the slot 111, the card plate 121 abuts against the limit switch to keep it in a closed state; when the card plate 121 is removed from the slot 111, the card plate 121 no longer abuts against the limit switch, keeping it in an open state; based on the state of the limit switch, the locking state of the battery 120 in the battery compartment 110 can be determined.

[0064] The above description is merely an optional embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0065] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
