Description

Technical Field

[0001] This utility model relates to the field of conductive sheet technology for new energy batteries, and in particular to a precision conductive sheet for new energy. Background Technology

[0002] Currently, the battery forms emerging in the new energy vehicle market are diverse. Major automakers use batteries of corresponding models that they are good at or have cooperated with in. Most existing batteries are manufactured in one piece, and the main part of the battery directly adopts ordinary batteries that are relatively mature and mass-produced in the market, without the need for additional development and verification. Therefore, the main technological innovation of new energy companies lies in the collection and transmission of current, and the conductive sheet of the battery module is one of them. The new energy of the conductive sheet directly affects the driving range and operational stability of new energy vehicles.

[0003] Existing conductive copper strips can improve the performance of battery modules for new energy vehicles. However, these strips are typically installed onto the battery box using screws. This process is usually cumbersome, as it requires manual operation and external tools.

[0004] Chinese utility model patent CN202122336021.9 discloses a conductive copper sheet that can improve the performance of new energy vehicle battery modules. It uses a set insert plate and a vertical plate to insert the insert plate and vertical plate below the conductive copper sheet body into the battery box plate. Then, the push plate is pressed down, the limiting block moves out of the limiting groove, and pushes the push plate to drive the moving plate to move in the auxiliary box. The plate disassembly structure drives the insert plate on the movable plate to move and insert the insert plate into the slot, restricting the vertical position of the insert plate and vertical plate, and installing the conductive copper sheet body onto the battery box plate, so that the conductive copper sheet body and the battery box plate can be quickly installed.

[0005] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: by horizontally inserting the insert plate into the slot on the side of the vertical plate to vertically limit and fix the conductive sheet, the conductive sheet is prone to wobbling in the vertical direction due to the gap between the insert plate and the slot, which reduces the fixing firmness of the conductive sheet and thus reduces the performance and reliability of the conductive sheet. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a precision conductive sheet for new energy applications.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a new energy precision conductive sheet, including a battery box cover and two conductive copper sheets, wherein the two conductive copper sheets are symmetrically fixedly connected to the top of the battery box cover by a connecting component;

[0008] The connecting assembly includes two pairs of symmetrically positioned holes on the top of the battery compartment cover. It also includes two pairs of symmetrically fixedly connected to two conductive copper sheets. The bottoms of the two positioning blocks are movably inserted into the two pairs of positioning holes and extend to the lower side of the battery compartment cover. A slot is provided on the right side of each pair of positioning blocks. The connecting assembly also includes two pairs of pressure plates and a pressing mechanism connected to the bottom of the battery compartment cover. The two pairs of pressure plates are connected to the pressing mechanism, which is used to press the two pairs of pressure plates against the inner bottom wall of the slot.

[0009] By adopting the above technical solution, the pressing mechanism drives two pairs of pressure plates to press against the inner bottom walls of two pairs of slots, making the pressing force perpendicular to the top surface of the battery box cover. This ensures that the conductive copper sheet will not wobble up and down after being connected to the battery box cover, improving the connection stability between the conductive copper sheet and the battery box cover. This also ensures the connection stability between the conductive copper sheet and external conductive components, ensuring that the current is safely and stably guided to external devices. It also allows the conductive sheet to be used in more precise new energy battery modules, improving the precision of the conductive sheet.

[0010] Furthermore, the pressing mechanism includes two pairs of rotating units, with the two pairs of pressure plates respectively connected to the two pairs of rotating units. The pressing mechanism also includes two transmission units connected to the bottom of the battery compartment cover. The two pairs of rotating units are symmetrically connected to the two transmission units. The two transmission units drive the two pairs of pressure plates to rotate through the rotating units until they are pressed against the bottom wall of the slot. The pressing mechanism also includes two limiting units connected to the bottom of the battery compartment cover. The two transmission units are respectively connected to the two limiting units, and the limiting units are used to limit and fix the transmission units.

[0011] Furthermore, the rotating unit includes a fixed plate, a mounting cavity is formed on the left side of the fixed plate, a first rotating shaft is rotatably connected between the front and rear inner sidewalls of the mounting cavity, a rotating plate is fixedly sleeved on the outer circumferential surface of the first rotating shaft, the right side of the pressure plate is fixedly connected to the left side of the rotating plate, two fixed rings are symmetrically fixedly sleeved on the outer circumferential surface of the first rotating shaft, two first elastic elements are symmetrically fixedly connected between the opposite sides of the two fixed rings and the front and rear inner sidewalls of the mounting cavity, two gears are symmetrically fixedly sleeved on the outer circumferential surface of the first rotating shaft, the rotating unit also includes two racks symmetrically fixedly connected to the front and rear sides of the limiting block, the two racks mesh with the two gears respectively, the fixed plate is connected to a transmission unit, and the transmission unit is used to push the fixed plate to move left and right.

[0012] By adopting the above technical solution, the fixed plate is pushed to the left by the transmission unit. The fixed plate will drive the two gears to move to the left until they mesh with the two racks. The meshing of the racks will drive the gears to rotate and drive the pressure plate to rotate downwards through the first rotating shaft and the rotating plate until it is pressed tightly against the inner bottom wall of the slot. In this way, the pressure plate can be stably and smoothly pressed against the inner bottom wall of the slot.

[0013] Furthermore, the transmission unit includes two sliding sleeves symmetrically fixedly connected to the bottom of the battery box cover. Two push rods are symmetrically and movably inserted into the two sliding sleeves. Two pairs of fixed plates are symmetrically fixedly sleeved on the outer circumferential surfaces of the two push rods. A push plate is fixedly connected between the right ends of the two push rods. The push plate is connected to the limiting unit.

[0014] By adopting the above technical solution, simply pushing the push plate to the left will cause the fixed plate to move to the left via the push rod. This allows for easy pressing of the pressure plate against the bottom wall of the slot, making the connection between the conductive copper sheet and the battery box cover simple and convenient, and improving the usability of the conductive sheet.

[0015] Furthermore, the limiting unit includes two pairs of straight rods symmetrically and movably inserted into the bottom of the two push plates. A pull plate is fixedly connected between the bottom ends of each pair of two straight rods. Two second elastic members are symmetrically and fixedly connected between the top of the pull plate and the bottom of the push plate. The top ends of the two straight rods pass through the push plate and are symmetrically and fixedly connected to two insert blocks. The limiting unit also includes two pairs of fixing blocks symmetrically and fixedly connected to the bottom of the battery box cover. Two slots are symmetrically opened at the bottom of each pair of two fixing blocks. The two pairs of insert blocks can be movably inserted into the two pairs of slots and pressed tightly against the inner wall of the slots.

[0016] By adopting the above technical solution, it is only necessary to pull down the pull plate to disengage the insert from the slot, and then the push plate can be pushed to the left by the pull plate. Conversely, it is only necessary to release the pull plate to allow the insert to be inserted into the slot to complete the limiting and fixing of the push plate. This further reduces the operational difficulty of connecting the conductive copper sheet and the battery box cover, and effectively improves the convenience and reliability of the conductive sheet.

[0017] Furthermore, the cross-sections of the insert and the slot are both isosceles trapezoids with the same slope. The height of the insert is less than the depth of the slot, and the two inclined sides of the insert can respectively abut against the inner sidewalls of the two inclined sides of the slot.

[0018] By adopting the above technical solution, it is ensured that the plug will not wobble left and right after being inserted into the slot. This ensures that the pressure plate firmly presses the limiting block, thus ensuring the stability of the connection between the conductive copper sheet and the battery box cover.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. In this application, a connecting component is provided. The pressing mechanism drives two pairs of pressure plates to press against the inner bottom walls of two pairs of slots respectively, so that the pressing force is perpendicular to the top surface of the battery box cover. This ensures that the conductive copper sheet will not wobble up and down after being connected to the battery box cover, thus improving the connection stability between the conductive copper sheet and the battery box cover. This also ensures the connection stability between the conductive copper sheet and external conductive components, ensuring that the current is safely and stably guided to external devices. It also allows the conductive sheet to be used in more precise new energy battery modules, improving the precision of the conductive sheet.

[0021] 2. In this application, by using the transmission unit, the push plate only needs to be pushed to the left to drive the fixed plate to move to the left via the push rod. This makes it easy to press the pressure plate against the bottom wall of the slot, making the connection between the conductive copper sheet and the battery box cover simple and convenient, and improving the convenience of the conductive sheet.

[0022] 3. In this application, by using the limiting unit, the pull plate only needs to be pulled down to disengage the insert from the slot, and then the push plate can be pushed to the left by the pull plate. Conversely, by simply releasing the pull plate, the insert can be inserted into the slot to complete the limiting and fixing of the push plate, which further reduces the operational difficulty of connecting the conductive copper sheet and the battery box cover, and effectively improves the convenience and reliability of the conductive sheet.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-7 As shown in the figure, this application discloses a new energy precision conductive sheet, including a battery box cover 1 and two conductive copper sheets 2. The two conductive copper sheets 2 are symmetrically fixedly connected to the top of the battery box cover 1 by a connecting component 3.

[0033] The connecting component 3 includes two pairs of limiting holes 31 symmetrically opened on the top of the battery box cover 1. The connecting component 3 also includes two pairs of limiting blocks 32 symmetrically fixedly connected to two conductive copper sheets 2. The bottom of the two limiting blocks 32 is movably inserted into the two pairs of limiting holes 31 and extends to the lower side of the battery box cover 1. The right side of the two pairs of limiting blocks 32 is provided with a slot 33. The connecting component 3 also includes two pairs of pressure plates 34. The connecting component 3 also includes a pressing mechanism 35 connected to the bottom of the battery box cover 1. The two pairs of pressure plates 34 are connected to the pressing mechanism 35. The pressing mechanism 35 is used to drive the two pairs of pressure plates 34 to press against the inner bottom wall of the slot 33.

[0034] Two top posts 21 are symmetrically fixedly connected to the bottom of the two conductive copper sheets 2. The two top posts 21 pass through the two limiting blocks 32 respectively and can contact the positive and negative terminals of the battery, so that the current of the battery is conducted to the conductive copper sheets 2.

[0035] Specifically, the pressing mechanism 35 drives two pairs of pressure plates 34 to press against the inner bottom walls of two pairs of slots 33, making the pressing force perpendicular to the top surface of the battery box cover 1. This ensures that the conductive copper sheet 2 will not wobble after being connected to the battery box cover 1, improving the connection stability between the conductive copper sheet 2 and the battery box cover 1. This also ensures the connection stability between the conductive copper sheet 2 and external conductive components, ensuring that the current is safely and stably guided to external devices. It also allows the conductive sheet to be used in more precise new energy battery modules, improving the precision of the conductive sheet.

[0036] See Figures 3-7 The pressing mechanism 35 includes two pairs of rotating units 351, and two pairs of pressure plates 34 are respectively connected to the two pairs of rotating units 351. The pressing mechanism 35 also includes two transmission units 352 connected to the bottom of the battery box cover 1. The two pairs of rotating units 351 are symmetrically connected to the two transmission units 352. The two transmission units 352 drive the two pairs of pressure plates 34 to rotate through the rotating units 351 until they are pressed against the bottom wall of the slot 33. The pressing mechanism 35 also includes two limiting units 353 connected to the bottom of the battery box cover 1. The two transmission units 352 are respectively connected to the two limiting units 353. The limiting units 353 are used to limit and fix the transmission units 352.

[0037] See Figures 4-6 The rotating unit 351 includes a fixed plate 3511, with an installation cavity on the left side of the fixed plate 3511. A first rotating shaft 3512 is rotatably connected between the front and rear inner walls of the installation cavity. A rotating plate 3513 is fixedly sleeved on the outer circumferential surface of the first rotating shaft 3512. The right side of the pressure plate 34 is fixedly connected to the left side of the rotating plate 3513. Two fixed rings 3514 are symmetrically fixedly sleeved on the outer circumferential surface of the first rotating shaft 3512. Two first elastic elements are symmetrically fixedly connected between the sides of the two fixed rings 3514 that are far apart and the front and rear inner walls of the installation cavity. Two gears 3515 are symmetrically fixedly sleeved on the outer circumferential surface of the first rotating shaft 3512. The rotating unit 351 also includes two racks 3516 symmetrically fixedly connected to the front and rear sides of the limiting block 32. The two racks 3516 mesh with the two gears 3515 respectively. The fixed plate 3511 is connected to the transmission unit 352, which is used to push the fixed plate 3511 to move left and right.

[0038] Specifically, the transmission unit 352 pushes the fixed plate 3511 to move to the left. The fixed plate 3511 will drive the two gears 3515 to move to the left until they mesh with the two racks 3516. The meshing of the racks 3516 drives the gears 3515 to rotate and, through the first rotating shaft 3512 and the rotating plate 3513, drives the pressure plate 34 to rotate downward until it is pressed tightly against the inner bottom wall of the slot 33. This allows the pressure plate 34 to be pressed stably and smoothly against the inner bottom wall of the slot 33.

[0039] See Figure 2 and Figure 4 The transmission unit 352 includes two sliding sleeves 3521 symmetrically fixedly connected to the bottom of the battery box cover 1. Two push rods 3522 are symmetrically and movably inserted into the two sliding sleeves 3521. Two pairs of fixing plates 3511 are symmetrically fixedly sleeved on the outer circumferential surface of the two push rods 3522. A push plate 3523 is fixedly connected between the right ends of the two push rods 3522. The push plate 3523 is connected to the limiting unit 353.

[0040] Specifically, simply pushing the push plate 3523 to the left will cause the fixed plate 3511 to move to the left via the push rod 3522. This allows the pressure plate 34 to press against the bottom wall of the slot 33, making the connection between the conductive copper sheet 2 and the battery box cover 1 simple and convenient, thus improving the usability of the conductive sheet.

[0041] See Figure 2 , Figure 4 and Figure 7 The limiting unit 353 includes two pairs of straight rods 3531 symmetrically and movably inserted into the bottom of two push plates 3523. A pull plate 3532 is fixedly connected between the bottom ends of each pair of two straight rods 3531. Two second elastic members are symmetrically and fixedly connected between the top of the pull plate 3532 and the bottom of the push plate 3523. The top ends of the two straight rods 3531 pass through the push plate 3523 and are symmetrically and fixedly connected to two insert blocks 3533. The limiting unit 353 also includes two pairs of fixing blocks 3534 symmetrically and fixedly connected to the bottom of the battery box cover 1. Two slots 3535 are symmetrically opened at the bottom of each pair of two fixing blocks 3534. The two pairs of insert blocks 3533 can be movably inserted into the two pairs of slots 3535 and pressed tightly against the inner wall of the slots 3535.

[0042] Specifically, simply pull down the pull plate 3532 to disengage the insert 3533 from the slot 3535, and then push the push plate 3523 to the left via the pull plate 3532. Conversely, simply release the pull plate 3532 to allow the insert 3533 to be inserted into the slot 3535 to complete the limiting and fixing of the push plate 3523. This further reduces the operational difficulty of connecting the conductive copper sheet 2 and the battery box cover 1, and effectively improves the convenience and reliability of the conductive sheet.

[0043] See Figure 7 Both the insert 3533 and the slot 3535 have cross-sections that are isosceles trapezoids with the same slope. The height of the insert 3533 is less than the depth of the slot 3535. The two inclined waist surfaces of the insert 3533 can be tightly pressed against the two inclined waist inner walls of the slot 3535 respectively.

[0044] Specifically, this ensures that the insert 3533 does not wobble left or right after being inserted into the slot 3535. This ensures that the pressure plate 34 firmly presses the limit block 32, thus ensuring the stability of the connection between the conductive copper sheet 2 and the battery box cover 1.

[0045] Working principle: Insert the two limiting blocks 32 at the bottom of the conductive copper sheet 2 into the corresponding limiting holes 31 respectively, and then pull down the pull plate 3532 so that the insert block 3533 is directly below the bottom of the slot 3535. Then the push plate 3523 can be pushed to the left by the pull plate 3532.

[0046] At this time, the push plate 3523 drives the fixed plate 3511 to move to the left via the push rod 3522. Then, the fixed plate 3511 drives the two gears 3515 to move to the left until they mesh with the two racks 3516. The meshing of the racks 3516 drives the gears 3515 to rotate and drives the pressure plate 34 to rotate downward through the first rotating shaft 3512 and the rotating plate 3513 until it presses tightly against the inner bottom wall of the slot 33. This allows the pressure plate 34 to be pressed stably and smoothly against the inner bottom wall of the slot 33.

[0047] Then, release the pull plate 3532. Under the elastic force of the second elastic element, the insert 3533 will be inserted into the slot 3535. The two inclined waist surfaces of the insert 3533 can respectively press against the two inclined waist inner side walls of the slot 3535 to limit and fix the push plate 3523. In this way, the connection operation between the conductive copper sheet 2 and the battery box cover 1 can be completed.

[0048] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
