[0054] The following specific implementation methods will further illustrate the present application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0055] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0056] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a centrally disposed element at the same time. When an element is considered to be "disposed on" another element, it may be directly disposed on the other element or there may be a centrally disposed element at the same time.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present application belongs. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0058] The embodiment of the present application provides a battery fixing device that can be used to safely, conveniently and quickly replace batteries. It can be used to fix and quickly replace power batteries of mobile robots, and can also be used in other scenarios where batteries need to be fixed and quickly replaced, such as electric passenger cars.

[0059] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0060] See also Figure 1 One embodiment of the present application provides a battery fixing device 100 for safely, conveniently and quickly replacing a battery 200. The battery fixing device 100 includes a first bracket 10 and a second bracket 20. The first bracket 10 is provided with a slide 11, and the slide 11 includes a main slide 111 and two side slides 112. The main slide 111 is parallel to a first direction, which is the X direction. The side slide 112 is parallel to a second direction, which is the Y direction. The X direction and the Y direction mentioned herein include both the positive and negative directions of the X direction and the Y direction. The side slide 112 is connected to the main slide 111. The second bracket 20 includes a frame 21 and a slider 22. The slider 22 is fixedly connected to the frame 21. The slider 22 includes two slides 221. The two slides 221 can slide in the main slide 111 relative to the first bracket 10 along the X direction at the same time, and the two slides 221 can slide in the corresponding side slides 112 relative to the first bracket 10 along the Y direction at the same time. The second bracket 20 is used to contact the battery 200 in the X direction and / or the Y direction.

[0061] When the second bracket 20 of the battery fixing device 100 moves, it drives the slider 22 to move in the slide groove 11. The slider 22 includes two sliding bodies 221, so that the slider 22 changes from point force to line force when it moves under force, thereby increasing the stability of the slide during the movement. In addition, the second bracket 20 will not deflect when it moves relative to the first bracket 10, and the movement is more stable. The inner wall of the slide groove 11 of the first bracket 10 is used to limit the displacement of the slider 22 in the X direction or the Y direction.

[0062] It can be understood that the slide 11 can also be configured as two main slides 111 and one side slide 112, the main slide 111 is parallel to the X direction, the side slide 112 is parallel to the Y direction, and the main slide 111 is connected to the side slide 112. The two slides 221 can slide in the corresponding main slides 111 relative to the first bracket 10 along the X direction, and the two slides 221 can slide in the side slides 112 relative to the first bracket 10 along the Y direction at the same time.

[0063] It is understandable that the number of the main slide 111 and the side slide 112 of the slide 11 is not limited to one or two, and can be set to multiple according to other practical applications. For example, multiple side slides 112 can be set in the Y direction, and different side slides 112 can be used to position batteries 200 of different heights, thereby increasing the application range of the battery fixing device 100.

[0064] See also Figure 1 and Figure 2The side slide 112 also has a stopper 1121, which is located at the end of the side slide 112 and is used to position the slider 22. When the slider 22 moves to the end of the side slide 112, it quickly enters the stopper 1121, so that the entire battery fixing device 100 can quickly reach a locked state.

[0065] The battery fixing device 100 further includes an elastic member 12 . One end of the elastic member 12 is connected to the first bracket 10 , and the other end of the elastic member 12 is connected to the second bracket 20 . The elastic member 12 is used to position the second bracket 20 .

[0066] Specifically, the elastic member 12 is a tension spring, one end of which is detachably connected to the first bracket 10, and the other end of which is detachably connected to the slider 22 of the second bracket 20. The detachable connection can be directly fixed by a spring hook or indirectly fixed by a bolt.

[0067] The resilience of the tension spring acts on the second bracket 20 through the slider 22 , so that the second bracket 20 can be positioned more stably when the battery 200 is fixed or replaced.

[0068] When the battery 200 is fixed, the resilience of the elastic member 12 acts on the second bracket 20 through the slider 22, so that the second bracket 20 is tightly attached to the battery 200, which can limit the displacement of the battery 200 and make the fixed state more stable. When the battery 200 is replaced, the resilience of the elastic member 12 acts on the second bracket 20 through the slider 22, so that the second bracket 20 can remain stationary while being away from the battery 200, so that the battery 200 can be replaced conveniently, quickly and safely.

[0069] It is understandable that the elastic member 12 may also be other elements with the same function, such as a rubber spring, a compression spring, etc.

[0070] The slider 22 includes a first component 222 and a second component 223 . The second component extends on the surface of the first component in a direction perpendicular to the first component. The first component 222 is fixedly connected to the elastic member 12 , and the second component 223 is fixedly connected to the two slide bodies 221 .

[0071] By setting the first component 222 and the second component 223, both can be connected to other components, so that the slider is convenient for fixed connection with other components. The angle α of the dihedral angle of the plane where the first component 222 and the second component 223 are located is set to 90°, which can reduce the surface area of ​​the first bracket.

[0072] Specifically, the first component 222 and the second component 223 adopt an integrally formed vertical design. It can be understood that the angle α of the dihedral angle of the plane where the first component 222 and the second component 223 are located can also be other angles, such as 60°≤α≤120°, which can better meet the requirement of reducing the surface area of ​​the first bracket.

[0073] The frame 21 includes a main frame 211 and a side frame 212. The side frame 212 extends on the surface of the main frame 211 in a direction perpendicular to the main frame 211. The main frame 211 is used to contact the battery 200, and the side frame 212 is used to connect with the slider 22. When in a fixed position, the main frame 211 contacts the battery 200, exerts pressure in a contact direction on the battery 200, and increases the stability and reliability of the fixation. By providing the side frame 212, the connection surface of the main frame 211 parallel to the first direction and the second direction is expanded, and it can be more convenient to be fixedly connected with the slider 22.

[0074] It can be understood that the angle between the plane where the side frame 212 is located and the plane where the main frame 211 is located is determined according to the shape of the battery 200 .

[0075] Specifically, the side frame 212 is detachably connected to both end surfaces of the main frame 211, the main frame 211 includes a first connection portion 2111, and the side frame 212 includes a second connection portion 2121, and the first connection portion 2111 is detachably connected to the second connection portion 2121. The main frame 211 and the side frame 212 are detachably connected, which facilitates the installation and removal of various components of the battery fixing device 100.

[0076] Specifically, the first connection part 2111 and the second connection part 2121 are connected by bolts and nuts. It can be understood that the connection between the first connection part 2111 and the second connection part 2121 can also be detachably connected by other forms such as magnets and adhesives.

[0077] The main frame 211 includes a third component 2112 and a fourth component 2113 . The fourth component 2113 extends on the surface of the third component 2112 in a direction perpendicular to the third component 2112 .

[0078] Specifically, the third component 2112 and the fourth component 2113 are integrally formed vertically. It is understandable that the third component 2112 and the fourth component 2113 can also be designed separately, and the two can be fixedly connected at an adjustable angle, and the fixed angle can be determined according to actual use, that is, the shape of the battery 200.

[0079] The frame 21 includes an elastic gasket 23, which is detachably connected to the frame 21 and is used to contact the battery 200. By providing the elastic gasket 23, the frame 21 and the battery 200 are indirectly in contact, thereby reducing the friction loss caused by the contact force of the frame 21. At the same time, the elastic gasket 23 is detachably provided, which is convenient for replacing the worn elastic gasket 23.

[0080] Specifically, the elastic gasket 23 is a POM (Polyoxymethylene (Polyformaldehyde) sheet. POM refers to a type of weakly polar linear thermoplastic polymer containing oxymethylene repeating structural units in the molecular chain. POM generally has high mechanical strength and comprehensive performance and is an excellent engineering plastic. It is widely used in automobiles, household appliances, equipment, mechanical structures, tools, electronics and consumables industries. It is used in many moving parts such as gears, deflection pulleys, ratchets or adjustment rods due to its good sliding friction, and is also used for quick connection due to its excellent resilience. The elastic gasket 23 made of POM has high mechanical strength and comprehensive performance, which can increase the reliability of the battery fixing device 100. At the same time, the elastic gasket 23 made of POM also has excellent resilience, which makes the battery fixing device 100 have a shock-absorbing effect during use.

[0081] The frame 21 includes a handle 24 , which is provided to facilitate the user to hold the frame 21 during use. The handle 24 and the frame 21 are integrally formed to reduce the number of process steps.

[0082] It can be understood that the handle 24 can also be detachably connected to the frame 21 to facilitate replacement of the handle 24.

[0083] Specifically, the handle 24 can be designed into any shape that is convenient for the user to hold, such as a plate shape, a ring shape, a handle shape, etc. The handle 24 can be made of plastic, hardware, wood, rope, etc.

[0084] See also Figure 3 and Figure 4 On the other hand, the embodiment of the present application provides a mobile robot, including the battery fixing device 100, which is fixedly connected to the mobile robot device. By setting the above battery fixing device 100, the mobile robot device can fix the battery 200 in the device and replace it safely, conveniently and quickly, thereby improving the use efficiency of the device.

[0085] The battery fixing device 100 includes a third connection portion 13, and the mobile robot device includes a fourth connection portion (not shown), and the third connection portion 13 is detachably connected to the fourth connection portion. The battery fixing device 100 and the mobile robot device are detachably connected, which facilitates the removal and replacement of the battery fixing device 100.

[0086] Specifically, the third connection part 13 is connected to the fourth connection part by bolts and nuts. It can be understood that the connection between the third connection part 13 and the fourth connection part can also be detachably connected by other forms such as magnets and adhesives.

[0087] See also Figure 3 , the battery 200 in the mobile robot device is in a fixed state, at this time the slider 22 is stationary on the main slide 111, the resilience of the elastic member 12 acts on the main frame 211 through the slider 22, and the third component 2112 and the fourth component 2113 of the main frame 211 are tightly fitted on the battery 200, making the battery 200 more stable in a fixed state.

[0088] See also Figure 4 , the battery 200 in the mobile robot device is in a replacement state. The slider 22 is stationary on the side slide 112, and the resilience of the elastic member 12 acts on the main frame 211 through the slider 22, so that the main frame 211 remains stationary.

[0089] See also Figure 3 , the battery fixing device 100 is in a fixed state. When the battery 200 needs to be replaced, the second bracket 20 drives the slider 22 to move in the main slide 111 along the X direction by using the handle 24. When the slider 22 moves to the connecting part of the main slide 111 and the side slide 112, the second bracket 20 drives the slider 22 to move in the side slide 112 along the Y direction by using the handle 24. When the slider 22 moves to the stopper 1121, the slider 22 is quickly locked and the second bracket 20 is locked and positioned. At this time, the main bracket 211 is separated from the battery 200, and the battery 200 can be quickly replaced.

[0090] See also Figure 4 , the battery fixing device 100 is in the replacement state. When the battery 200 needs to be fixed, the handle 24 is pulled so that the second bracket 20 drives the slider 22 to disengage from the stopper 1121 and move along the Y direction in the side slide 112. When the slider 22 moves to the connection between the main slide 111 and the side slide 112, the slider 22 enters the main slide 111. Under the action of the rebound force of the elastic member 12, the slider 22 is quickly locked. At this time, the third component 2112 and the fourth component 2113 of the main frame 211 are tightly attached to the battery 200, making the battery 200 more stable in the fixed state.

[0091] In addition, those skilled in the art may also make other changes within the spirit of the present application. Of course, these changes made according to the spirit of the present application should be included in the scope disclosed in the present application.
