Description

Technical Field

[0001] The utility model relates to the field of power battery brackets, in particular to a power battery supporting device. Background Art

[0002] With the popularity of electric vehicles in recent years, pure electric commercial vehicles have been increasingly used in municipalities, ports, on-site transportation, mines, etc., relying on their advantages of zero emissions, low noise and low cost of use. Commercial vehicle power batteries are large in size, large in number, and need to be installed in a centralized manner. Traditional pure electric trucks generally use a backpack battery pack, where all batteries are placed in layers in a large battery frame, installed above the frame and behind the cab.

[0003] This solution has the advantages of strong wading ability, centralized batteries, and simple layout. However, this solution has the following disadvantages:

[0004] The center of mass is high; the batteries are stacked in multiple layers, making it inconvenient to disassemble and maintain the batteries; the design needs to avoid collision between the batteries and the cargo box, which occupies the frame space, thus reducing the available length of the frame and affecting the turning radius of the vehicle; the batteries are located behind the cab, which limits the driver's rearward field of vision. Utility Model Content

[0005] In order to solve the above technical problems or at least partially solve the above technical problems, the utility model provides a power battery supporting device.

[0006] The utility model provides a power battery support device, comprising a probe-type bottom bracket, on which a bottom protective plate is laid, and on which two power batteries arranged transversely relative to a vehicle frame are fixed side by side;

[0007] The two support frames are respectively fixedly arranged on both sides of the probe-type bottom bracket perpendicular to the side walls of the frame, and the two support frames are arranged away from the frame. A plurality of fixing holes for connecting the power battery support device to the side walls of the frame are arranged on one side of the two support frames close to the frame. When the support frames are connected to the frame, the probe-type bottom bracket probes into the bottom of the frame;

[0008] The support frame is divided into three layers: upper, middle and lower. The middle layer is fixedly provided with a horizontal pull-out support frame that supports horizontal pulling out, and a single power battery arranged longitudinally relative to the frame is fixed on the horizontal pull-out support frame. The upper layer is fixedly provided with a support structure that supports vertical pulling out, and a single power battery arranged longitudinally relative to the frame is fixed on the support structure.

[0009] Furthermore, the bottom protective plate is provided with a plurality of holes and grooves for heat dissipation and drainage.

[0010] Furthermore, a top support frame is detachably fixedly arranged between the tops of the two support frames, a protective top plate is fixedly arranged on the top support frame, and protective side plates are arranged between the two support frames on one side away from the frame and on the two support frames.

[0011] Furthermore, a pull-out slide of the horizontal pull-out support frame is arranged between the bottom layer and the middle layer of the support frame, and the pull-out slide includes two L-shaped plates fixed to each of the support frames, and the two L-shaped plates on the same support frame are distributed up and down to cooperate to form a channel for accommodating the horizontal pull-out support frame.

[0012] Furthermore, the length of the lower L-shaped plate is greater than that of the top L-shaped plate, and the two L-shaped plates are aligned at one end close to the frame, and the fixing part of the horizontal pull-out support frame is provided at one end of the lower L-shaped plate away from the frame.

[0013] Furthermore, a support member of the support structure is arranged between the middle layer and the top layer of the support frame, and the support member includes two L-shaped frames fixed to each of the support frames, and a fixing portion of the support structure is arranged on each of the L-shaped frames.

[0014] Furthermore, a support rod slot perpendicular to the frame is provided at the bottom of the probe-type base, and the support rod slot is used to insert a support member connected to the frame, and a fixing portion of the support member is provided in the support rod slot.

[0015] The height of the power battery supporting device is lower than the upper wing surface of the vehicle frame.

[0016] The above technical solution provided by the embodiment of the utility model has the following advantages compared with the prior art:

[0017] The battery support device provided by the utility model can be installed on the side wall of the frame longitudinal beam. Compared with the existing installation method, it does not occupy the effective length of the frame. While ensuring the same effective length of the frame as the existing design, the total length of the vehicle can be reduced and the minimum turning diameter can be reduced. There is no obstruction behind the cab, which improves the driver's field of vision.

[0018] In this application, two power batteries are arranged horizontally relative to the frame on the bottom layer, and single power batteries are arranged on the second and third layers, respectively, with a low overall center of mass. The inserted bottom bracket is inserted into the inner side of the frame, and the second and third layers of power batteries are arranged longitudinally relative to the frame, which can effectively control the width of the vehicle and arrange as many power batteries as possible to increase the vehicle's mileage.

[0019] The power batteries on the bottom and middle layers of the present application can be conveniently pulled out horizontally without disassembling each layer for inspection, and the power batteries on the top layer can be conveniently pulled out vertically from the top, making battery maintenance simple.
