[0044] See also Figure 1 and 2 , a new energy vehicle battery bracket proposed in an embodiment of the present utility model includes at least one supporting unit 1 and two side panels 2;

[0045] When there are multiple support units 1, the multiple support units 1 are arranged at intervals in the upper and lower parts; each support unit 1 can support and be detachably connected to a battery; each support unit 1 includes two longitudinal beams 11 and at least one cross beam 12; the two longitudinal beams 11 are arranged in parallel and at intervals, and the two ends of at least one cross beam 12 are respectively connected to the two longitudinal beams 11, and the lengths of the two longitudinal beams 11 and the at least one cross beam 12 are adjustable; the two side panels 2 are arranged opposite to each other, and the two ends of the longitudinal beam 11 in each support unit 1 can be detachably connected to the two side panels 2.

[0046] The utility model provides a battery bracket for new energy vehicles, which is provided with at least one support unit 1. When the number of support units 1 is multiple, the multiple support units 1 are spaced apart from each other, and both ends of the longitudinal beam 11 in each support unit 1 can be detachably connected to the two side panels 2, thus forming a battery bracket. Each support unit 1 can form a space for accommodating a battery with the two side panels 2. Each support unit 1 supports and can be detachably connected to a battery. The structure is simple and convenient for loading and unloading and maintenance. At the same time, the two longitudinal beams 11 and the two cross beams 12 in each support unit 1 are adjustable in length to adjust the length and width of the support unit 1, and are suitable for supporting batteries of different lengths and widths, so as to expand the adaptability of the battery bracket and reduce the manufacturing cost, thereby reducing the manufacturing cost of new energy vehicles.

[0047] For the convenience of explanation, hereinafter, the length direction of the longitudinal beam 11 is defined as the length direction of the support unit 1 , and the length direction of the transverse beam 12 is defined as the width direction of the support unit 1 .

[0048] Preferably, the number of support units 1 is two, so that the two support units 1 support two batteries in a one-to-one correspondence, meeting the battery quantity requirement of most new energy vehicles.

[0049] Furthermore, the specific structure of the length adjustment of the support unit 1 is as follows:

[0050] Each longitudinal beam 11 includes a first telescopic portion 111 and two first fixing portions 112 ; the two first fixing portions 112 are coaxially spaced apart, and first threaded holes 1121 are defined at opposite ends of the two first fixing portions 112 . The walls of both ends of the first telescopic portion 111 are provided with opposite threads; the two ends of the first telescopic portion 111 can be respectively inserted into and threadedly connected to the first threaded holes 1121 of the two first fixing portions 112 ;

[0051] When the first telescopic portion 111 rotates, the distance between the two first fixing portions 112 increases or decreases to adjust the length of the longitudinal beam 11 and further adjust the length of the support unit 1. This adjustment method is simple and convenient.

[0052] The specific structure of the width adjustment of the support unit 1 is as follows:

[0053] Each crossbeam 12 includes a second telescopic portion 121 and two second fixing portions 122 ; the two second fixing portions 122 are coaxially spaced apart, and second threaded holes 1221 are defined at opposite ends of the two second fixing portions 122 . The walls of both ends of the second telescopic portion 121 are provided with opposite threads; the two ends of the second telescopic portion 121 can be respectively inserted into and threadedly connected to the second threaded holes 1221 of the two second fixing portions 122 ;

[0054] When the second telescopic portion 121 rotates, the distance between the two second fixing portions 122 increases or decreases to adjust the length of the beam 12 and further adjust the width of the support unit 1. This adjustment method is simple and convenient.

[0055] Preferably, first locking holes 1123 are formed on the sidewalls of the two first fixing portions 112 of each longitudinal beam 11 at opposite ends thereof. A locking member can be threadedly connected in the first locking holes 1123 , and an end portion of the locking member can press against the first telescopic portion 111 inserted into the first threaded hole 1121 .

[0056] When the length of the longitudinal beam 11 needs to be adjusted, the locking member is rotated to unlock the first telescopic portion 111. Subsequently, the first telescopic portion 111 is rotated to adjust the length of the longitudinal beam 11. After the length adjustment of the longitudinal beam 11 is completed, the locking member is rotated to press against the first telescopic portion 111 to lock the first telescopic portion 111, thereby preventing the first telescopic portion 111 from shifting and improving the support stability of the longitudinal beam 11.

[0057] The side walls of the opposite ends of the two second fixing portions 122 of each beam 12 are provided with second locking holes 1222 , in which a locking member can be threadedly connected, and an end of the locking member can press against the second telescopic portion 121 inserted into the second threaded hole 1221 .

[0058] When the length of the crossbeam 12 needs to be adjusted, the locking member is rotated to unlock the second telescopic portion 121, and then the second telescopic portion 121 is rotated to adjust the length of the crossbeam 12. After the length adjustment of the crossbeam 12 is completed, the locking member is rotated to press against the second telescopic portion 121 to lock the second telescopic portion 121, preventing the second telescopic portion 121 from shifting and improving the support stability of the crossbeam 13.

[0059] Optionally, the locking member is a grub screw.

[0060] Specifically, each longitudinal beam 11 is provided with a plurality of third mounting holes 1124 spaced apart along its length direction. Fasteners can be passed through the third mounting holes 1124 to detachably connect the batteries.

[0061] By providing a plurality of third mounting holes 1124 on the longitudinal beam 11 , after adjusting the length and width of the support unit 1 , the mounting holes on the battery can still selectively connect to the plurality of third mounting holes 1124 and pass fasteners therethrough for connection.

[0062] Optionally, the fastener is a screw.

[0063] Specifically, both ends of at least one crossbeam 12 in each support unit 1 are respectively welded, riveted or screwed to the two longitudinal beams 11;

[0064] Specifically, the first telescopic portion 111 of the longitudinal beam 11 is a beam body with a circular cross section, and the first fixed portion 112 is a beam body with a circular, U-shaped or rectangular cross section.

[0065] When the first fixing portion 112 is a beam with a circular cross-section, the opposing ends of the two first fixing portions 112 of each longitudinal beam 11 are internally threaded. When the first fixing portion 112 is a beam with a U-shaped or rectangular cross-section, an internally threaded connector is fixedly disposed within the opposing ends of the two first fixing portions 112 of each longitudinal beam 11.

[0066] Specifically, the second telescopic portion 121 of the crossbeam 12 is a beam body with a circular cross section, and the second fixed portion 122 is a beam body with a circular, U-shaped or rectangular cross section.

[0067] When the second fixing portion 122 has a circular cross-section, the two second fixing portions 122 of each crossbeam 12 have internal threads at their opposite ends. When the second fixing portion 122 has a U-shaped or rectangular cross-section, the two second fixing portions 122 of each crossbeam 12 have internal threads fixedly disposed at their opposite ends.

[0068] Preferably, the connecting head is welded to the first fixing portion 112 and the second fixing portion 122 .

[0069] Furthermore, mounting beams 21 are fixedly provided on opposite surfaces of the two side panels 2, and a plurality of vertically oriented first mounting holes 211 are horizontally spaced apart on the mounting beams 21;

[0070] Vertically oriented second mounting holes 1122 are respectively defined at both ends of the longitudinal beam 11. The ends of the longitudinal beam 11 can be mounted on the mounting beams 21 of the two side panels 2. The second mounting holes 1122 can communicate with the corresponding first mounting holes 211 to allow fasteners to penetrate through them, thereby detachably connecting the ends of the longitudinal beam 11 to the two side panels 2. Optionally, the fasteners are screws.

[0071] Therefore, by opening a plurality of first mounting holes 211 on the mounting beams 21 of the two side panels 2, the length of at least one cross beam 12 in each support unit 1 is adjusted to change the spacing between the two longitudinal beams 11. The second mounting holes 1122 at both ends of the two longitudinal beams 11 can still correspond to one of the plurality of first mounting holes 211 on the mounting beams 21 connecting the two side panels 2, so that the two ends of the longitudinal beam 11 can be fixed to the two side panels 2 by fasteners.

[0072] It should be noted that, since the longitudinal beam 11 and the side panel 2 are detachably connected, the side panel 2 having a size corresponding to the length of the cross beam 12 can be replaced to further expand the length adjustment range of the cross beam 12 and further expand the width adjustment range of the support unit 1.

[0073] Furthermore, the cross-sections of the two side panels 2 are both relatively L-shaped; a vertical portion of each side panel 2 is detachably connected to one end of the longitudinal beam 11, and a horizontally oriented fourth mounting hole 22 is provided on the other vertical portion. Fasteners can be passed through the fourth mounting hole 22 to be detachably connected to the frame of the new energy vehicle, so as to facilitate loading and unloading and maintenance between the battery bracket and the frame.

[0074] Specifically, a plurality of weight-reducing holes are provided on both side panels 2 to reduce the weight of the battery bracket, and at least one side panel 2 is also provided with a threading hole 23 for the wires on the battery to pass through.

[0075] Furthermore, the battery bracket further comprises at least one support frame 4;

[0076] The support frame 4 is L-shaped, and one vertical portion of the support frame 4 is detachably connected to the side wall of the longitudinal beam 11; when the number of support units 1 is one, the other vertical portion of the support frame 4 is detachably connected to the bottom of the longitudinal beam 11. When the number of support units 1 is multiple, the other vertical portion of the support frame 4 is detachably connected to the bottom of the longitudinal beam 11 of the lowest support unit 1 among the multiple support units 1. The support frame 4 can assist in supporting multiple support units 1 and improve the supporting strength of the support unit 1 for the battery. It should be noted that the other vertical portion of the support frame 4 is detachably connected to the first fixed portion 112 of the longitudinal beam 11. When the length of the longitudinal beam 11 is adjusted, the support frame 4 does not need to be disassembled to reduce the difficulty of adjustment.

[0077] Optionally, the other vertical portion of the support frame 4 is detachably connected to the longitudinal beam 11 by screws.

[0078] Specifically, the support frame 4 is provided with a horizontally oriented fifth mounting hole 41, and a fastener can be passed through the fifth mounting hole 41 to detachably connect the frame, so as to further improve the connection strength between the battery bracket and the frame and facilitate the loading and unloading and maintenance between the battery bracket and the frame.

[0079] Optionally, the fastener is a screw.

[0080] It should be noted that the fourth mounting hole (22) on the side panel 2 and the fifth mounting hole 41 on the support frame 4 are suitable for connecting to one side of the vehicle frame so as to hang the battery bracket to one side of the vehicle frame.

[0081] Furthermore, when there are multiple support units 1, the new energy battery bracket also includes multiple vertically oriented support beams 3, and the two ends of the multiple support beams 3 can be detachably connected to the two upper and lower opposite longitudinal beams 11 of two adjacent support units 1 to improve the supporting strength of each support unit 1 for the battery, and facilitate the loading and unloading and maintenance of the support beams 3 and the longitudinal beams 11.

[0082] Optionally, the mounting holes formed on the mounting seats at the upper and lower ends of the support beam 3 can be connected to the mounting holes on the two upper and lower opposite longitudinal beams 11 and can be detachably connected by fasteners. Preferably, the fasteners are screws.

[0083] Optionally, the cross-section of the support beam 3 is U-shaped, circular or rectangular to reduce the difficulty of selection.

[0084] Furthermore, the battery bracket further comprises a horizontally oriented support plate 5;

[0085] When there is only one support unit 1, the support plate 5 is detachably connected to the bottom of the two longitudinal beams 11 of the support unit 1 and is detachably connected to the two side panels 2. When there are multiple support units 1, the support plate 5 can be detachably connected to the bottom of the two longitudinal beams 11 of the lowest support unit 1 and is detachably connected to the two side panels 2.

[0086] The support plate 5 can further improve the supporting strength of the support unit 1 for the battery.

[0087] It should be noted that, after the length and width of the support unit 1 are adjusted, support plates 5 of different lengths and widths may be selected accordingly to be adapted and connected thereto.

[0088] Preferably, a plurality of weight-reducing holes are provided on the support plate 5 to reduce the weight of the support plate 5 , thereby reducing the manufacturing cost of the new energy vehicle.

[0089] It should be noted that the support unit 1, side panel 2, support beam 3, support frame 4 and support plate 5 in the battery bracket of this new energy vehicle can be detachably connected to avoid welding defects between the structures that lead to overall scrapping, and damaged structures can be replaced in time to extend the service life of the battery bracket and reduce the cost of the battery bracket.
