Detailed Implementation

[0036] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation and not by way of limitation. In fact, those skilled in the art will recognize that modifications and variations can be made to the present application without departing from the scope or spirit thereof. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. Therefore, it is desirable that the present application encompass such modifications and variations that fall within the scope of the appended claims and their equivalents.

[0037] First, it should be noted that in this application, the height direction of the battery mounting unit 100 is defined as the first direction, the length direction as the second direction, and the width direction as the third direction.

[0038] like Figures 1 to 14 As shown, the battery box mounting structure based on shared electric vehicles includes: a battery mounting unit 100 and a quick-release connector 200. Multiple battery mounting units 100 are arranged side-by-side, with adjacent battery mounting units 100 connected by the quick-release connector 200. Each battery mounting unit 100 has a trapezoidal cross-section quick-release connecting groove 104 on its opposite sides; the quick-release connecting groove 104 penetrates the battery mounting unit 100 along a first direction.

[0039] The quick-release connector 200 is adapted to be installed in the corresponding quick-release connection slots 104 of two adjacent battery mounting units 100, wherein half of the quick-release connector 200 is located in the quick-release connection slot 104 of one battery mounting unit 100, and the other half is located in the corresponding quick-release connection slot 104 of the other battery mounting unit 100.

[0040] In this application, quick-release connecting slots 104 are symmetrically provided on two sides of the battery mounting unit 100 in the width direction, so that when two battery mounting units 100 are arranged side by side, their quick-release connecting slots 104 face each other. A quick-release connector 200 is inserted into the two quick-release connecting slots 104 along the height direction to connect and fix the two battery mounting units 100 together. Here, a certain distance can be left between adjacent battery mounting units 100 to allow for heat dissipation. After the quick-release connector 200 connects the two battery mounting units 100, it serves both as a connector and as a means of mutual constraint, enhancing the stability of the battery mounting units 100.

[0041] The quick-release connector 200 located in the battery mounting unit 100 also has a trapezoidal structure, which enables a tight connection to the battery mounting unit 100, avoids possible displacement of the battery mounting unit 100 in the length and width directions, and effectively improves the stability of the battery mounting unit 100.

[0042] In this application, the battery mounting unit 100 includes: a housing 101, a base plate 102, and a top cover 103. The housing 101 is provided with a cell mounting cavity 111, a first wiring hole 121, and a second wiring hole 131. The cell mounting cavity 111 extends through the housing 101 along a first direction. The first wiring hole 121 extends upward from the bottom surface of the housing 101 along the first direction. The second wiring hole 131 extends from the side wall of the housing 101 along a second direction, and the first wiring hole 121 and the second wiring hole 131 are interconnected and intersect.

[0043] Furthermore, a countersunk hole 141 is provided on the top surface of the hull 101. The countersunk hole 141 is coaxially arranged with the first through hole 121 along the height direction, and the diameter of the countersunk hole 141 is larger than the diameter of the first through hole 121. The second through hole 131 is connected to the first through hole 121 through the countersunk hole 141. That is to say, the bottom surface of the countersunk hole 141 is located below the second through hole 131. Through the design of the countersunk hole 141, the wiring can be guided from the top surface of the hull 101 through the countersunk hole 141 during the wiring process, improving the efficiency and visibility of the wiring.

[0044] In this application, the shape of the battery cell mounting cavity 111 can be rectangular, circular, etc., depending on the specific shape of the battery cell, and is not limited to this. A portion of the quick-release connection groove 104 is symmetrically arranged on the two side walls opposite each other in the width direction of the housing 101, and a second wire hole 131 is vertically arranged on the side wall in the length direction, so that it communicates with the first wire hole 121 along the height direction.

[0045] The base plate 102 is detachably connected to the bottom surface of the housing 101. The top surface of the base plate 102 is provided with a first wire groove countersunk hole 112 facing the cell mounting cavity 111. The first wire groove countersunk hole 112 is connected to the first wire hole 121, so that wiring can be carried out sequentially through the first wire groove countersunk hole 112, the first wire hole 121, and the second wire hole 131 to connect the cell to the power adapter (or other components).

[0046] The base plate 102 is connected to the bottom surface of the compartment 101 at its four corners by connecting bolts. The base plate 102 has countersunk holes 122 at its four corners, allowing the heads of the connecting bolts to be recessed into these holes, preventing them from protruding and further enhancing the stability of the battery mounting unit 100 during installation. On the two side walls of the base plate 102 along its width, portions of quick-release connecting grooves 104 are symmetrically provided, directly opposite to portions of the quick-release connecting grooves 104 on the compartment 101.

[0047] In this application, the top cover 103 is also detachably connected to the top surface of the cabin 101. The top cover 103 has symmetrical quick-release connecting grooves 104 on its two side walls along the width direction. At the same time, multiple first positioning holes are evenly distributed at the four corners of the top surface of the cabin 101, and multiple first positioning posts are correspondingly provided on the top cover 103. During the installation process, the first positioning posts are inserted into the first positioning holes, so that the quick-release connecting grooves 104 on the top cover 103 are aligned with the quick-release connecting grooves 104 on the cabin 101.

[0048] Furthermore, there are two battery cell mounting cavities 111, two first wiring holes 121, and two second wiring holes 131, with the two battery cell mounting cavities 111 arranged side by side; the two first wiring holes 121 are arranged side by side, and the two second wiring holes 131 are arranged side by side, with the two first wiring holes 121 intersecting the two second wiring holes 131 respectively. Two first wire groove countersunk holes 112 are also provided on the top surface of the base plate 102. One end of each of the two first wire groove countersunk holes 112 is connected to the corresponding battery cell mounting cavities 111, and the other end is connected to the corresponding lower end of each of the two first wiring holes 121. Therefore, when two battery cells are arranged side by side in the same compartment 101, wiring can be performed through the corresponding first wire groove countersunk holes 112, first wiring holes 121, and second wiring holes 131, avoiding wiring errors and improving safety.

[0049] Meanwhile, when two cell mounting cavities 111 are arranged in the housing 101, two second countersunk holes 113 are correspondingly arranged on the bottom surface of the top cover 103. The two second countersunk holes 113 are directly opposite the two cell mounting cavities 111, and the two second countersunk holes 113 are connected. This facilitates the series or parallel connection of two cells installed side by side, improving the convenience and versatility of cell installation.

[0050] Furthermore, a first wire passage groove 151 and a second wire passage groove 161 are provided on the side wall of the housing 101. The first wire passage groove 151 extends along the height direction and passes through the second wire hole 131; the second wire passage groove 161 extends along the width direction, and there are two second wire passage grooves 161, which intersect with the two ends of the first wire passage groove 151 respectively. When there are two battery cell mounting cavities 111, two first wire passage grooves 151 are arranged side by side at the corresponding two second wire holes 131, and the two ends of the two first wire passage grooves 151 are connected to the two second wire passage grooves 161. In this way, the first wire passage grooves 151 and the second wire passage grooves 161 can facilitate separate wiring of the two parallel battery cells for incoming, outgoing, series, and parallel connections, further improving the versatility and safety of the wiring. Here, when multiple battery mounting units 100 are arranged in parallel, the second wire groove 161 on each battery mounting unit 100 is aligned, which effectively improves the series and parallel connection and incoming and outgoing wires between battery cells when multiple battery mounting units 100 are arranged in parallel, making the wiring more reasonable and effectively avoiding wiring chaos.

[0051] In this application, a first locking countersunk hole 171 is provided on the side wall of the cabin 101, which has a partial quick-release connection groove 104, and a second locking countersunk hole 123 is provided on the side wall of the top cover 103, which also has a partial quick-release connection groove 104. The first locking countersunk hole 171 and the second locking countersunk hole 123 communicate at the joint surface between the top cover 103 and the cabin 101. In addition, a locking groove 133 is provided on the top cover 103. The locking groove 133 is located between the top surface of the top cover 103 and the side wall with the partial quick-release connection groove 104. A locking through hole 143 is provided in the locking groove 133, directly opposite the bottom surface of the side wall with the partial quick-release connection groove 104. The locking through hole 143 communicates with the second locking countersunk hole 123.

[0052] One end of the locking device 105 of the battery mounting unit 100 is located in the first locking countersunk hole 171 and the second locking countersunk hole 123, abutting against the bottom surface of the first countersunk hole and the bottom surface of the second countersunk hole; the other end of the locking device 105 passes through the locking through hole 143 and is installed in the locking groove 133, and abuts against the bottom surface of the locking groove 133. Specifically, the locking device 105 includes a first locking block 115, a locking spring 135 and a second locking block 125. The two ends of the locking spring 135 are respectively connected to the first locking block 115 and the second locking block 125. The first locking block 115 is adapted to the first locking countersunk hole 171 and the second locking countersunk hole 123, and the locking block is adapted to the locking groove 133. In this way, the first locking block 115 is pulled and pressed against the first locking countersunk hole 171 and the second locking countersunk hole 123 by the locking spring 135, and the second locking block 125 is pulled and pressed against the locking groove 133.

[0053] In this application, a locking device 105 is used to lock the top cover 103 to the cabin 101. The first locking block 115 includes a first horizontal part, a second horizontal part, and a vertical connecting part. One end of the first horizontal part is connected to one end of the vertical connecting part, and the other end of the vertical connecting part is connected to the middle of the second horizontal part. The first horizontal part and the second horizontal part are parallel. Thus, the upper parts of the first horizontal part and the vertical connecting part are installed in the first locking countersunk hole 171, and the lower parts of the second horizontal part and the vertical connecting part are installed in the T-shaped second locking countersunk hole 123, thereby achieving a locking connection between the top cover 103 and the cabin 101.

[0054] Two second positioning holes 181 are provided on the bottom surface of the first locking countersunk hole 171 along the width direction, and two second positioning pins 145 are correspondingly provided on the second horizontal part. During the installation of the first locking block 115, the two second positioning pins 145 are inserted into the two second positioning holes 181 respectively, so that the first locking block 115 can be installed more accurately in the first locking countersunk hole 171 and the second locking countersunk hole 123. On the one hand, the installation accuracy is improved, and on the other hand, the first locking block 115 can be limited in the height direction, further improving the tightness and firmness of the connection between the first locking block 115 and the top cover 103 and the cabin 101.

[0055] Threaded countersunk holes are provided on the first horizontal part and the second locking block 125 respectively. Hooks are installed in the threaded countersunk holes. The two ends of the locking spring 135 are connected to the hooks respectively, so that a tension is formed between the first locking block 115 and the second locking block 125, which pulls the first locking block 115 to abut against the first locking countersunk hole 171 and the second locking countersunk hole 123, and pulls the second locking block 125 to abut against the locking groove 133.

[0056] Furthermore, on the two side walls of the housing 101 where the quick-release connection grooves 104 are provided, a second locking countersunk hole 123 is provided respectively. On the two side walls of the top cover 103 where the quick-release connection grooves 104 are provided, a first locking countersunk hole 171 and a locking groove 133 are provided respectively. The first locking countersunk hole 171 and the locking groove 133 facing the top cover 103 are connected by a locking through hole 143. A locking device 105 is installed in the corresponding first locking countersunk hole 171, second locking countersunk hole 123, locking groove 133 and locking through hole 143 of the housing 101 and the top cover 103, so that the two sets of locking devices 105 are arranged in opposite positions on the battery mounting unit 100, so that the corresponding sides of the housing 101 and the top cover 103 are locked and connected, enhancing the firmness of the connection between the housing 101 and the top cover 103.

[0057] The battery box installation structure of this application enables rapid replacement of electric vehicle batteries, greatly extending the effective deployment time and usage frequency of electric vehicles; at the same time, it can adapt to different numbers of battery installation units 100 according to different power levels of electric vehicles; on the other hand, it can also enable centralized charging of replaced batteries, effectively reducing the space occupied by electric vehicles during charging and improving the safety of battery charging.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
