DETAILED DESCRIPTION

[0044] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the scheme of the embodiments of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0045] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the utility model, but the embodiments of the utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the utility model, rather than all of the embodiments.

[0046] Reference Figures 1 to 10 As shown, this embodiment provides a battery installation structure, including a bracket shell 1, a host back cover 2, a battery 3, a battery positive electrode assembly 4, a battery negative electrode assembly 5 and a control board 6.

[0047] The control board 6 is disposed on the support housing 1 , and the battery positive electrode assembly 4 is disposed on the support housing 1 and is used for conducting with the control board 6 and the positive electrode of the battery 3 .

[0048] The bracket housing 1 has a receiving cavity 11, and the battery 3 is detachably located in the receiving cavity 11. The mainframe rear cover 2 is arranged at the cavity opening of the receiving cavity 11 and has a through hole 21 communicating with the receiving cavity 11. When the battery 3 is installed, the battery negative electrode assembly 5 is clamped in the through hole 21 and is used to conduct with the control board 6 and the negative electrode of the battery 3. When the battery 3 is removed, the battery negative electrode assembly 5 is unclamped from the through hole 21.

[0049] When implementing it, refer to Figure 1 In the upper and lower directions of the drawings shown, the control board 6 can be arranged above the bracket shell 1, and the battery positive electrode assembly 4 is arranged on the bracket shell 1 and can be respectively connected to the control board 6 and the positive electrode of the battery 3, thereby realizing electrical conduction between the positive electrode of the battery 3 and the control board 6.

[0050] Further, the bracket housing 1 has a receiving cavity 11, and the battery 3 can be installed in the receiving cavity 11. The mainframe rear cover 2 can be arranged at the cavity opening of the receiving cavity 11, and a through hole 21 communicating with the receiving cavity 11 is arranged on the mainframe rear cover 2. When the battery 3 is installed, the battery 3 can be partially located in the receiving cavity 11 and partially extended into the through hole 21, or the battery 3 can be completely located in the receiving cavity 11, and the battery negative electrode assembly 5 extends into the through hole 21 so as to be connected with the positive electrode of the battery 3 located in the receiving cavity 11 and the control board 6, thereby realizing electrical conduction between the negative electrode of the battery 3 and the control board 6.

[0051] Specifically, at least a portion of the battery negative electrode assembly 5 is inserted into the through hole 21 and then connected to the through hole 21 by snapping. After the battery 3 is installed, the battery negative electrode assembly 5 is snapped to the through hole 21, which is equivalent to the battery negative electrode assembly 5 covering or blocking the through hole 21, so that the battery 3 can be in a closed space enclosed by the bracket housing 1, the main body rear cover 2 and the battery negative electrode assembly 5, thereby ensuring the closed installation of the battery 3.

[0052] When the battery 3 needs to be removed for repair or replacement, the battery negative electrode assembly 5 can be directly unfastened from the main unit back cover 2, and then the battery negative electrode assembly 5 can be removed. At this time, the through hole 21 is equivalent to being in an open state, and then the battery 3 in the accommodating cavity 11 can be taken out through the cavity opening of the accommodating cavity 11 and the through hole 21 in turn for repair or replacement.

[0053] Exemplarily, the size of the accommodating cavity 11 in the direction from the bracket shell 1 to the host back cover 2 can be larger than the size of the battery 3 in the direction from the bracket shell 1 to the host back cover 2, or can be set to be equal to the size of the battery 3 in the direction from the bracket shell 1 to the host back cover 2, so as to achieve that the battery 3 as a whole can be completely accommodated in the accommodating cavity 11. Alternatively, the size of the accommodating cavity 11 in the direction from the bracket shell 1 to the host back cover 2 can be smaller than the size of the battery 3 in the direction from the bracket shell 1 to the host back cover 2. In this case, the battery 3 is partially located in the accommodating cavity 11 and partially located in the through hole 21, which is more conducive to shortening the distance between the battery 3 and the battery negative electrode assembly 5, and then achieving contact and conduction between the two.

[0054] In addition, the inner contour of the accommodating cavity 11 can be adapted to the outer contour of the battery 3 , so that the battery 3 will not shake significantly and generate shaking noise after being installed in the accommodating cavity 11 .

[0055] Exemplarily, the support housing 1 and the host back cover 2 can be connected by fasteners or can be bonded or clamped. In addition, the control board 6 and the support housing 1 can also be connected by fasteners or clamped.

[0056] The battery installation structure of this embodiment includes a bracket housing 1, a host back cover 2, a battery 3, a battery positive electrode assembly 4, a battery negative electrode assembly 5 and a control board 6. By setting the control board 6 on the bracket housing 1 and setting the battery positive electrode assembly 4 on the bracket housing 1, the battery positive electrode assembly 4 can be connected to the control board 6 and the positive electrode of the battery 3 respectively, so as to achieve the connection between the positive electrode of the battery 3 and the control board 6. By setting the bracket housing 1 with a receiving cavity 11, when the battery 3 is installed, the battery 3 is accommodated in the receiving cavity 11, and a host back cover 2 with a through hole 21 is provided at the cavity opening of the receiving cavity 11, and the host back cover 2 is engaged with the battery negative electrode assembly 5 for connecting the negative electrode of the battery 3 and the control board 6. When the battery 3 needs to be disassembled for replacement or repair, it is only necessary to disassemble and separate the battery negative electrode assembly 5 and the host back cover 2, and then take out the battery 3 in the receiving cavity 11 from the through hole 21, and the whole operation is simple and quick.

[0057] Reference Figure 2 , Figure 3 and Figure 7 As shown, in some embodiments, a first clamping portion 51 is provided on the outer wall of the battery negative electrode assembly 5, and a second clamping portion 211 is provided on the hole wall of the through hole 21 at a position corresponding to the first clamping portion 51. The first clamping portion 51 can be engaged with the second clamping portion 211 when a portion of the battery negative electrode assembly 5 extends into the through hole 21, thereby realizing the clamping connection between the battery negative electrode assembly 5 and the main unit back cover 2, so that the two can be quickly assembled and connected or disassembled and separated.

[0058] Reference Figure 2 , Figure 3 and Figure 7 As shown, in some embodiments, the first clamping portion 51 includes an elastic clamping body 511 arranged on the outer wall of the battery negative electrode assembly 5, and a clamping protrusion 512 is arranged on the side of the elastic clamping body 511 away from the outer wall of the battery negative electrode assembly 5, and the second clamping portion 211 includes a clamping mating position 212 that is clamped with the clamping protrusion 512.

[0059] During assembly, the battery 3 is installed in the accommodating cavity 11 through the through hole 21, and then part of the battery negative electrode assembly 5 is inserted into the through hole 21. The snap-fitting protrusion 512 on the elastic snap-fitting body 511 is squeezed and contacted with the inner wall of the through hole 21, and then the snap-fitting protrusion 512 is squeezed toward the outer wall of the battery negative electrode assembly 5 so that the elastic snap-fitting body 511 is squeezed and deformed. As the battery negative electrode assembly 5 continues to be inserted until the snap-fitting protrusion 512 is snapped into the snap-fitting position 212, the elastic snap-fitting body 511 can recover its deformation. At this time, it can be considered that the battery negative electrode assembly 5 is inserted into place and is snap-fitted and fixed by the snap-fitting fit between the snap-fitting protrusion 512 and the snap-fitting position 212, thereby preventing the battery negative electrode assembly 5 from being detached from the back cover 2 of the main unit.

[0060] When disassembly and separation is required, a pressing force can be manually applied to the snap-fitting protrusion 512 or the elastic snap-fitting body 511 in the direction close to the outer wall of the battery negative electrode assembly 5, so that the snap-fitting protrusion 512 moves in the direction away from the snap-fitting position 212 and squeezes the elastic snap-fitting body 511 until the snap-fitting protrusion 512 is moved out of the snap-fitting position 212, and then the battery negative electrode assembly 5 is moved out of the through hole 21, and then the battery 3 can be taken out through the through hole 21 to realize the subsequent maintenance or replacement of the battery 3. The whole operation is simple and quick.

[0061] Illustratively, the snap-fitting position 212 may be a snap-fitting groove or a snap-fitting hole adapted to the snap-fitting protrusion 512 .

[0062] For example, in one implementation, the elastic clamping body 511 may be a block made of a material having elastic deformation capability, such as rubber or silicone, so that the elastic clamping body 511 may be squeezed and deformed to drive the clamping protrusion 512 to move out of the clamping fitting position 212. Alternatively, in another implementation, the elastic clamping body 511 may be a spring sheet with one end suspended in the air. The structure of the elastic clamping body 511 in the specific embodiment is described in detail below.

[0063] For example, refer to Figure 3 As shown, the snap-fit ​​protrusion 512 may be as follows Figure 3The cross section of the protrusion 512 is shown as a triangle, or the cross section of the snap-fit ​​protrusion 512 may also be a rectangle or other shapes. In addition, the formation structure of the snap-fit ​​position 212 may be: the inner wall of the through hole 21 is provided with a top protrusion protruding toward the direction close to the snap-fit ​​protrusion 512, and the top protrusion and the inner wall of the through hole 21 may jointly form a snap-fit ​​position 212 that can snap-fit ​​with the snap-fit ​​protrusion 512.

[0064] Alternatively, in other implementations, the first clamping portion 51 may also be a clamping fitting position provided on the outer wall of the battery negative electrode assembly 5 , and the second clamping portion 211 may be a clamping protrusion provided on the inner wall of the through hole 21 .

[0065] Reference Figure 1 , Figure 3 and Figure 7 As shown, in some embodiments, the elastic snap-fit ​​body 511 includes a spring sheet, an end of the spring sheet away from the bracket shell 1 is connected to the outer wall of the battery negative electrode assembly 5, a snap-fit ​​protrusion 512 is arranged at an end of the spring sheet close to the bracket shell 1, and a pressing gap 513 is provided between the end of the spring sheet close to the bracket shell 1 and the outer wall of the battery negative electrode assembly 5.

[0066] When implementing it, refer to Figure 1 In the left and right directions of the drawings shown, for example, the bracket housing 1 is set to be located on the left side of the host rear cover 2, and the battery negative electrode assembly 5 can be located on the right side of the host rear cover 2 and partially extend into the through hole 21 of the host rear cover 2. At this time, when the elastic snap-fitting body 511 is set as a spring, the right end of the spring can be connected to the outer wall of the battery negative electrode assembly 5, and a pressing gap 513 is formed between the left end of the spring and the outer wall of the battery negative electrode assembly 5, and the snap-fitting protrusion 512 is set at the left end of the spring, and then when the spring is pressed to make the snap-fitting protrusion 512 disengage from the snap-fitting position 212, sufficient movement gap is provided to the spring to allow the spring to move in a direction away from the snap-fitting position 212 after being pressed to drive the snap-fitting protrusion 512 to move out of the snap-fitting position 212.

[0067] In addition, the purpose of forming a pressing gap 513 between the end of the spring sheet close to the bracket shell 1 and the outer wall of the battery negative electrode assembly 5, rather than forming a pressing gap 513 between the end of the spring sheet away from the bracket shell 1 and the outer wall of the battery negative electrode assembly 5, and setting the snap-fitting protrusion 512 at the end of the spring sheet close to the bracket shell 1 is that the snap-fitting position 212 is located on the main unit back cover 2, so when the pressing gap 513 is formed between the end of the spring sheet close to the bracket shell 1 and the outer wall of the battery negative electrode assembly 5, the spring sheet can provide the snap-fitting protrusion 512 with sufficient movement travel along the pressing direction when being pressed, so that the snap-fitting protrusion 512 and the snap-fitting position 212 can be snapped or contact-engaged.

[0068] Exemplarily, the spring piece may be an alloy spring piece or a metal spring piece, and the spring piece may be welded or screwed to the battery negative electrode assembly 5 , or the spring piece may be integrally formed with the battery negative electrode assembly 5 .

[0069] Reference Figure 7 As shown, in some embodiments, a side of the spring sheet close to the outer wall of the battery negative electrode assembly 5 is provided with a pressing reinforcement structure 514 for adjusting the pressing force of the spring sheet, and the pressing reinforcement structure 514 is located at one end of the spring sheet close to the bracket shell 1.

[0070] That is, a pressing reinforcing structure 514 is provided on the side of the spring sheet opposite to the side provided with the clamping protrusion 512. The pressing reinforcing structure 514 can not only enhance the structural strength of the entire spring sheet, but also change the movement stroke of the spring sheet after being pressed by changing the thickness of the pressing reinforcing structure 514 along the pressing direction of the pressing force applied to the spring sheet, or in other words, can adjust the pressing force applied to the spring sheet by the operator. For example, when the thickness of the pressing reinforcing structure 514 is large, the required pressing force is small, and when the thickness of the pressing reinforcing structure 514 is small, the required pressing force is large.

[0071] Exemplarily, the pressing reinforcement structure 514 may be a reinforcement rib or a reinforcement block.

[0072] For example, the pressing reinforcement structure 514 and the spring sheet can be integrally formed to save manufacturing steps and improve the overall structural strength of the spring sheet. Alternatively, the pressing reinforcement structure 514 and the spring sheet can be connected by welding.

[0073] In addition, in the present embodiment, since a pressing gap 513 is formed between one end of the spring sheet close to the bracket shell 1 and the outer wall of the battery negative electrode assembly 5, the pressing reinforcement structure 514 can be arranged at the end of the spring sheet close to the bracket shell 1, so that the pressing reinforcement structure 514 can be located in the pressing gap 513 to adjust the pressing force applied to the spring sheet by changing the thickness of the pressing reinforcement structure 514.

[0074] In some embodiments, a side of the spring away from the outer wall of the battery negative electrode assembly 5 is provided with an anti-skid structure 515, so as to prevent slipping when pressing the spring. Exemplarily, the anti-skid structure 515 can be a protective groove or an anti-skid protrusion or an anti-skid pattern.

[0075] Reference Figure 1 , Figure 7 and Figure 8 As shown, in some embodiments, the battery negative electrode assembly 5 includes a negative electrode rear cover 52 , a negative electrode conductive assembly 53 and a negative electrode fixing seat 54 .

[0076] The negative electrode conducting assembly 53 is disposed on the negative electrode fixing seat 54 and is in contact and conduction with the control board 6 and the negative electrode of the battery 3 respectively. The negative electrode rear cover 52 is disposed on the outer periphery of the negative electrode fixing seat 54 and is engaged with the through hole 21 .

[0077] A first guide portion is provided on the negative electrode fixing seat 54 , and a second guide portion is provided on the main unit rear cover 2 . The first guide portion and the second guide portion cooperate to guide the battery negative electrode assembly 5 when the battery negative electrode assembly 5 is inserted into the through hole 21 .

[0078] That is to say, in the process of inserting the battery negative electrode assembly 5 into the through hole 21 and engaging the first engaging portion 51 with the second engaging portion 211, in order to ensure that the battery negative electrode assembly 5 can be accurately and reliably inserted without displacement or deflection that affects the alignment of the first engaging portion 51 and the second engaging portion 211, a first guide portion can be provided on the negative electrode fixing seat 54, and a second guide portion can be provided on the main unit rear cover 2, so that the battery negative electrode assembly 5 can be accurately inserted along a predetermined direction through the cooperation of the first guide portion and the second guide portion to avoid skewing during insertion.

[0079] Reference Figure 1 , Fig. 9 As shown, in some embodiments, one of the first guide portion and the second guide portion is a first guide rib 541 , and the other of the first guide portion and the second guide portion is a guide groove 22 plugged into and mated with the first guide rib 541 .

[0080] For example, refer to Figure 1 and Fig. 9 As shown, a first guide rib 541 can be provided on the negative electrode fixing seat 54, and a guide groove 22 can be provided on the main unit rear cover 2, wherein the extension direction of the guide groove 22 is parallel to the insertion direction of the battery negative electrode assembly 5, so that during the process of inserting the battery negative electrode assembly 5 into the through hole 21, the battery negative electrode assembly 5 slides in the guide groove 22 through the first guide rib 541, so as to guide the insertion process of the battery negative electrode assembly 5 and avoid the battery negative electrode assembly 5 from being skewed.

[0081] Alternatively, in other implementations, a guide groove 22 may be provided on the negative electrode fixing seat 54, and a first guide rib 541 may be provided on the main body rear cover 2, and the purpose of guiding the insertion process of the battery negative electrode assembly 5 may also be achieved by making the first guide rib 541 slide in the guide groove 22.
