[0055] like Figures 1 to 6 As shown, the present invention provides a lightweight vertical battery box structure, comprising:

[0056] Two outer carbon fiber panels 1 are formed by splicing two symmetrical outer carbon fiber panels 1 to form an outer frame of the battery box;

[0057] Two inner support plate mechanisms 2, each of which is distributed on the inner side of two outer carbon fiber plates 1 and has the same height;

[0061] The upper tray 3 is used to be fixed on the slide plate assembly 22 .

[0062] At present, most of the driving battery boxes in the industry are produced by metal casting, sheet metal, and stamping. Metal materials are prone to casting defects and the process is complicated. The consistency of products produced by sheet metal and stamping is poor. In addition, metal battery boxes have the disadvantages of being heavy, not insulated, having poor corrosion resistance, being easy to rust, and easily causing leakage and short circuit during use. They also require painting and post-protection treatment. The production processes are numerous, resulting in low production efficiency and increased costs, and cannot meet the development trend of lightweight and low-cost automobiles.

[0063] The present invention splits a conventional battery box structure into multiple independent structures, replaces the structure with larger volume and smaller force strength with carbon fiber material, and uses two trays for loading batteries to be respectively arranged at the bottom and middle positions for connecting the independent box structures, so that the independent box structures can be fixedly connected into an integrated structure, effectively reducing the weight of the device.

[0064] In addition, the battery module is generally installed in the battery box through a tray, but the conventional battery tray is fixedly connected to the battery box. Therefore, if the battery tray needs to be removed from the battery box for debugging again after installation, the operation will be more cumbersome.

[0065] The present invention connects the upper tray by arranging a directional sliding structure on the inner support plate, so that the commercial tray can slide on the inner support plate after being connected to the two inner support plates, and the overall connection effect of the battery box can still be guaranteed during the sliding process, and a locking structure is arranged under the inner support plate to lock the upper tray that slides to any position.

[0066] The outer carbon fiber panel 1 of the box is composed of a side panel 11 facing the side, a rear panel 12 facing the rear, and a bottom panel 13 facing the bottom.

[0070] A notch is formed on the rear plate 12 in an area above the upper tray 3, and a semicircular groove is formed on the rear plate 12 in an area below the inner support plate mechanism 2;

[0071] The two rear plates 12 can be spliced ​​together to form two notches into a U-shaped weight-reducing notch, and the two rear plates 12 can be spliced ​​together to form two semicircular grooves into a circular wire groove.

[0072] The side surface of the L-shaped inner support plate 21 is used to fit on the inner side of the carbon fiber plate 1 outside the box, and the top surface of the L-shaped inner support plate 21 is used to place the slide plate assembly 22;

[0073] The side surface of the L-shaped inner support plate 21 is provided with a plurality of second threaded holes 211 that overlap with the plurality of middle-layer through holes 112 on the side plate 11, and the top surface of the L-shaped inner support plate 21 is provided with a slide groove 212 and a plurality of locking plate grooves 213;

[0074] The orientation of the slide groove 212 is consistent with the orientation of the L-shaped inner support plate 21 , and the orientation of the plurality of locking plate grooves 213 equidistantly distributed on the L-shaped inner support plate 21 is consistent with the orientation of the slide groove 212 .

[0075] The slide assembly 22 includes a connecting slider 221 and a special-shaped slide 222, and a fixing bolt 223 is threadedly connected to the connecting slider 221. The fixing bolt 223 is screwed into the connecting slider 221 on the inner side of the upper tray 3 to fix the upper tray 3 and the slide assembly 22 into an integrated structure.

[0076] The connecting slider 221 can slide in the slide groove 212 of the L-shaped inner support plate 21. Two symmetrically distributed first positioning holes 2211 are provided at the top of the connecting slider 221. A plurality of slots 2212 communicating with the first positioning holes 2211 are provided on the side of the connecting slider 221.

[0077] The inner side of the first positioning hole 2211 is provided with an internal thread at the bottom end of the slot 2212 for matching with the fixing bolt 223 .

[0078] The end of the special-shaped slide plate 222 close to the connecting slide block 221 is fixedly connected with a plurality of insert blocks 2221, and the connecting slide block 221 extends into a plurality of slots 2212 of the connecting slide block 221 through the plurality of insert blocks 2221, and the insert blocks 2221 are provided with second positioning holes 2222 for the fixing bolts 223 to pass through;

[0079] The bottom end of the special-shaped slide plate 222 is provided with a plurality of equally spaced card slots 2223, and the plurality of card slots 2223 correspond one-to-one to the plurality of locking slots 213 on the L-shaped inner support plate 21;

[0080] The side of the special-shaped slide plate 222 away from the plug block 2221 is a hook-shaped structure that engages with the top side edge of the L-shaped inner support plate 21. One side of the special-shaped slide plate 222 engages with the L-shaped inner support plate 21 to limit the up and down movement of the special-shaped slide plate 222, and the other side of the special-shaped slide plate 222 engages with the L-shaped inner support plate 21 through the connecting slider 221 to limit the left and right movement of the special-shaped slide plate 222.

[0081] The locking mechanism 23 includes a connecting frame 231 fixed to the bottom end of the horizontal structure of the L-shaped inner support plate 21, a locking column 232 is rotatably connected to the connecting frame 231, a plurality of locking plates 233 are fixedly connected to the locking column 232, and a knob 234 for controlling the locking column 232 to rotate inside the connecting frame 231 is provided on the front end surface of the connecting frame 231;

[0082] The direction of the lock column 232 is consistent with the direction of the L-shaped inner support plate 21. The lock column 232 rotates in the connection frame 231 so that the multiple lock pieces 233 on the outer side of the lock column 232 can pass through the multiple lock piece grooves 213 on the L-shaped inner support plate 21 and snap into the multiple snap grooves 2223 at the bottom end of the special-shaped slide plate 222.

[0083] The locking column 232 can only be adjusted in angle by means of the knob 234 in the connection frame 231 .

[0084] Both sides of the upper tray 3 are provided with first threaded holes 31 corresponding to and overlapping with the plurality of upper through holes 113. A battery groove 32 is provided at the inner center of the upper tray 3, and four tray positioning holes 33 are provided inside the upper tray 3 and outside the battery groove 32;

[0085] The four tray positioning holes 33 respectively overlap with the two first positioning holes 2211 on the top surfaces of the two connecting sliders 221;

[0086] The structure of the lower tray 4 is the same as that of the upper tray 3 , and the outer side of the groove inside the lower tray 4 is provided with four positioning holes which respectively overlap with the threaded holes on the two bottom plates 13 .

[0087] When installing the battery box, the two L-shaped inner support plates 21 need to be installed on the side panels 11 connected to the two outer carbon fiber panels 1 respectively, and bolts are inserted into the middle layer through holes 112 on the outer sides of the side panels 11 and screwed into the second threaded holes 211 on the corresponding sides of the L-shaped inner support plates 21, so that the two L-shaped inner support plates 21 are fixed respectively on the inner middle layer positions of the two outer carbon fiber panels 1.

[0088] Then, the connecting sliders 221 are placed in the slide grooves 212 on the two L-shaped inner support plates 21, and then the multiple plug blocks 2221 on the two special-shaped slide plates 222 are extended into the multiple slots 2212 on the sides of each connecting slider 221 until the special-shaped slide plates 222 are attached to the horizontal structure at the top of the L-shaped inner support plate 21. At this time, the second positioning hole 2222 on the plug block 2221 is located in the first positioning hole 2211 on the connecting slider 221.

[0089] Then place the upper pallet 3 on the two connecting sliders 221, and adjust the position of the upper pallet 3 until the four pallet positioning holes 33 in the upper pallet 3 coincide with the first positioning holes 2211 on the two connecting sliders 221, and then pass the bolts through the pallet positioning holes 33 on the upper pallet 3 and screw them into the first positioning holes 2211 on the connecting sliders 221, until the fixing bolts 223 pass through the second positioning holes 2222 and are fixed on the internal threads on the inner side of the first positioning holes 2211, and until the fixing bolts 223 are all screwed into the four pallet positioning holes 33 of the upper pallet 3, at this time, the upper pallet 3 is fixedly connected to the two skateboard assemblies 22, and at this time, the two skateboard assemblies 22 are connected to the two outer carbon fiber panels 1 of the box through two L-shaped inner support plates 21 as an integrated structure.

[0090] Then, the lower tray 4 is placed on the bottom plates 13 of the two outer carbon fiber panels 1 , and bolts are put into the four positioning holes of the lower tray 4 and screwed into the threaded holes of the bottom plate 13 , so that the lower tray 4 is fixedly connected to the two bottom plates 13 .

[0091] The two carbon fiber panels outside the box are connected into an integrated structure through the upper tray 3 and the lower tray 4, and during subsequent use, the batteries are placed in the battery grooves 32 of the upper tray 3 and the lower tray 4, and supported by the L-shaped inner support plate 21 made of metal material to ensure the overall strength of the device.

[0092] When the position of the upper tray 3 needs to be adjusted, the upper tray 3 can be pulled outward so that the upper tray 3 can slide outward on the L-shaped inner support plate 21 through the two slide plate assemblies 22. At this time, the connecting slider 221 slides in the slide groove 212, and the special-shaped slider 222 slides outward on the L-shaped inner support plate 21.

[0093] When it is necessary to lock the position of the upper tray 3, it is necessary to turn the knob 234 to drive the lock column 232 to rotate in the connecting frame 231. As the lock column 232 rotates, multiple locking plates 233 fixed on the outside of the lock column 232 can be flipped to pass through the multiple locking plate grooves 213 of the L-shaped inner support plate 21 and extend into the multiple card slots 2223 at the bottom end of the special-shaped slide plate 222. At this time, the bottom end of the special-shaped slide plate 222 is inserted with multiple locking plates 233. Therefore, the special-shaped slide plate 222 cannot slide on the L-shaped inner support plate 21 at this time. Subsequently, you only need to turn the knob 234 to control whether the upper tray 3 is in a locked state.

[0094] The battery box of this embodiment is mainly used in trucks and vans. Therefore, in order to increase the cruising range of trucks and vans, before a major breakthrough in battery technology is achieved, it is necessary to improve the specific energy of the power system and it is particularly important to design the battery box to be lightweight.

[0095] In this embodiment, composite materials are used for some structures of the battery box that are larger in volume and require high strength, and metal materials are used for other structures that require higher strength. Independent metal material processing has higher processing accuracy than integrated stamping, so the scrap rate can be effectively reduced. In addition, the battery box adopts the design concept of metal material and composite material, which can also greatly reduce the weight of the vehicle body and increase the vehicle's cruising range.

[0096] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
