Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to a battery pack support bracket for a new energy vehicle. Background Technique

[0002] It varies slightly with different types of electric vehicles. In a pure electric vehicle equipped only with a storage battery, the storage battery serves as the sole power source for the vehicle drive system. In a hybrid electric vehicle equipped with a traditional engine (or fuel cell) and a storage battery, the storage battery can either play the role of the main power source of the vehicle drive system or act as an auxiliary power source. It can be seen that at low speeds and during startup, the storage battery plays the role of the main power source of the vehicle drive system; during full-load acceleration, it acts as an auxiliary power source; during normal driving, deceleration, or braking, it acts as an energy storage device. Usually, when using a new energy vehicle battery, a bracket for installing the battery is required.

[0003] The existing battery pack support brackets mostly use bolts to fix the battery pack to the bottom of the new energy vehicle. Workers need to carry tools to install or remove the bolts, and the number of bolts used for fixing in the support bracket is relatively large, making the whole process operation more cumbersome.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0044] Embodiment 1

[0045] Refer to Figures 1-4 , a battery pack carrier for a new energy vehicle, comprising a main body assembly 1, and the main body assembly 1 includes: a bottom frame 11, on which multiple groups of support frames 12 are symmetrically arranged facing each other; a loading and unloading assembly 2 is arranged on the bottom frame 11 and the support frames 12, and the loading and unloading assembly 2 includes: a bracket 21 symmetrically arranged on the top of the support frame 12; a first spring 221 symmetrically arranged on the top of the support frame 12; a support block 22 rotatably connected to the top of the bracket 21, and the support block 22 is fixedly connected to the top end of the first spring 221; a side plate 23 arranged on the top of the support block 22; a lead screw 24 rotatably connected in a through groove opened at the top of the bottom frame 11, and one end of the lead screw 24 penetrates and extends outside the bottom frame 11; a turning handle 241 arranged on the outer side wall of the bottom frame 11 and fixedly connected to the end of the lead screw 24 extending out of the lead screw 24; an optical axis 25 fixedly connected in the through groove opened at the top of the bottom frame 11; moving blocks 26 symmetrically arranged on the lead screw 24 and the optical axis 25, the moving blocks 26 are threadedly connected to the lead screw 24 and slidably connected to the optical axis 25; vertical frames 261 symmetrically arranged on the top of the moving blocks 26; horizontal frames 262 symmetrically arranged on the top of the vertical frames 261; a fixing mechanism 27 is arranged on the horizontal frames 262. The fixing mechanism 27 includes: a frame body 271 slidably connected to the facing surfaces of the horizontal frames 262; blind holes 272 symmetrically opened on the outer side wall of the frame body 271; a pressing plate 273 fixedly connected to the bottom of the frame body 271; grooves 274 symmetrically opened at the facing ends of the horizontal frames 262; a second spring 275, one end of which is fixedly connected to the inner wall of the groove 274; a limiting block 276 fixedly connected to the other end of the second spring 275, and the limiting block 276 is slidably connected in the groove 274; a pull rod 277 fixedly connected to the outer side wall of the limiting block 276, and the pull rod 277 extends outside the groove 274. Anti-slip patterns are arranged on both the top surface of the support block 22 and the facing surface of the side plate 23.

[0046] During use, the vertical frame 261 and the horizontal frame 262 are located at the edge positions. The staff places the battery pack on top of multiple support blocks 22. After the support blocks 22 are subjected to the gravity of the battery pack, they drive the side plates 23 to turn downward, and compress the first spring 221. The support blocks 22 rotate to a horizontal state and support the battery pack. The top side plates 23 rotate to a vertical state and fix the outside of the battery pack. Then, the handle 241 is rotated. The handle 241 drives the lead screw 24 to rotate. The moving block 26 threadedly connected to the lead screw 24 drives the top vertical frame 261 and the horizontal frame 262 to move. The other moving block 26 is driven by the horizontal frame 262 and the vertical frame 261 to slide on the optical axis 25, which is used to increase the stability of the movement of the horizontal frame 262 and the vertical frame 261. The position of the vertical frame 261 is adjusted by rotating the handle 241 so that the fixing mechanism 27 on the horizontal frame 262 is located at the center of the battery pack. The fixing mechanism 27 adjusts the position of the pressing plate 273 to facilitate the pressing plate 273 to fix the top of the battery pack: The limiting block 276 is located in the blind hole 272 in the initial state. The staff presses down the frame body 271. After the edge of the blind hole 272 touches the inclined surface at the top of the limiting block 276, the limiting block 276 is squeezed into the groove 274, and the second spring 275 is compressed. After the limiting block 276 retracts into the groove 274, the frame body 271 continues to move downward until the upper blind hole 272 and the limiting block 276 are on the same horizontal line. The second spring 275 pops the limiting block 276 into the current blind hole 272. By repeating the above operation, the pressing plate 273 at the bottom of the frame body 271 gradually approaches the battery pack until the pressing plate 273 contacts the top surface of the battery pack. At this time, the frame body 271 is no longer pressed downward, and the limiting block 276 stays in a certain blind hole 272 to restrict the upward movement of the frame body 271. Just pressing the frame body 271 can realize the adjustment and fixation of the battery pack, which improves the installation efficiency of the battery pack. When it is necessary to release the fixation of the battery pack, the staff first pulls the pull rods 277 to both sides simultaneously, so that the limiting block 276 disengages from the blind hole 272, moves the frame body 271 upward, releases the pull rods 277, and the limiting block 276 fixes the frame body 271. Then, the handle 241 is rotated to drive the horizontal frame 262 to drive the fixing mechanism 27 to move to the edge of the bottom frame 11. The battery pack is lifted upward. The elastic force of the first spring 221 pushes the support block 22 upward, and the side plate 23 automatically releases the fixation of the outside of the battery pack, which is convenient for removing the battery pack. The anti-slip patterns on the support block 22 and the side plate 23 are used to increase the friction when contacting the battery pack, which increases the firmness of the battery pack fixed by the support block 22 and the side plate 23.

[0047] Embodiment 2

[0048] On the basis of Embodiment 1, an auxiliary function is added.

[0049] Refer to Figures 1-4, the facing ends of the support blocks 22 have arc-shaped surfaces. An expansion link 222 is hinged between the support blocks 22 and the support frame 12, and the first spring 221 is sleeved outside the expansion link 222. Vent holes are symmetrically formed in the pressing plate 273.

[0050] The arc-shaped surface at the top of the support block 22 contacts the bottom of the battery pack when the battery pack is placed on the top of the support block 22. The arc-shaped surface facilitates the support block 22 to be adjusted horizontally in time and prevents the edge of the support block 22 from damaging the battery pack, affecting the safety of the battery pack during use. The expansion link 222 is a retractable hollow cylindrical rod made of a metal strip or a plastic sheet, which cannot expand and contract independently and moves with the movement of the support block 22. The lowest height after the expansion link 222 contracts is the same as the height of the support 21. The expansion link 222 provides auxiliary support for the other side of the support block 22 to prevent the support block 22 from tilting after placing the battery pack, affecting the stability of the fixed battery pack. The vent holes in the pressing plate 273 increase the heat dissipation area of the battery pack while not affecting the fixing effect of the pressing plate 273 on the top of the battery pack, enhancing the heat dissipation effect of the battery pack.

[0051] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
