[0004] However, when the above-mentioned device clamps and fixes the lithium battery, it lacks a corresponding elastic contact structure, resulting in the lithium battery not being fixed very tightly. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fixed bracket for installing automotive lithium batteries. Through the elastic contact clamping of the automotive lithium battery placement tray and the elastic contact plate, the automotive lithium battery body placed inside the automotive lithium battery placement tray can be stably placed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mounting bracket for installing automotive lithium batteries includes:

[0008] Car lithium battery placement tray;

[0009] A contact plate mounting bracket is fixedly attached to the outer walls of both ends of an automotive lithium battery placement tray;

[0010] An elastic contact plate is mounted on the upper end of a contact plate mounting bracket.

[0011] Through the above technical solution: the contact plate mounting bracket can be placed on both sides of the automotive lithium battery placement tray, and the elastic contact plate can be horizontally positioned above the automotive lithium battery placement tray through the contact plate mounting bracket. Thus, through the automotive lithium battery placement tray and the elastic contact plate, the outer shell of the automotive lithium battery placement tray passes through the area of ​​the automotive lithium battery tray mounting cavity, thereby allowing the automotive lithium battery body to be placed.

[0012] The present invention is further configured such that the automotive lithium battery placement tray includes an automotive lithium battery tray shell, an automotive lithium battery tray mounting cavity is formed on the upper inner side of the automotive lithium battery tray shell, an elastic clamp is fixedly connected to the inner side of the automotive lithium battery tray mounting cavity on the inner wall of the automotive lithium battery tray shell, an abutment plate mounting bracket is fixedly connected to both ends of the automotive lithium battery tray shell, and a screw lug is fixedly connected to the outer side of the abutment plate mounting bracket at the corner of the automotive lithium battery tray shell.

[0013] The above technical solution utilizes a tray structure for placing automotive lithium batteries, allowing for flexible and secure fixation.

[0014] The present invention is further configured such that the outer shell of the automotive lithium battery tray and the screw lug are fixedly connected by welding, and the bottom ends of the outer shell of the automotive lithium battery tray and the screw lug are aligned.

[0015] The above technical solution utilizes a screw lug structure, allowing the automotive lithium battery tray housing to be installed and placed using screws.

[0016] The present invention is further configured such that four abutment mounting brackets are provided, and the abutment mounting brackets are symmetrically installed on the outer shell of the automotive lithium battery tray.

[0017] The above technical solution allows for adjustable and fixed installation via the contact plate mounting bracket structure.

[0018] The present invention is further configured such that the contact plate mounting bracket includes a welding end block, the inner wall of the welding end block is fixedly connected to the outer shell of the automotive lithium battery tray, a connecting end rod is fixedly connected to the middle of the upper end of the welding end block, a metal screw is fixedly connected to the upper end of the connecting end rod, a locking nut is rotatably connected to the circumferential thread of the metal screw, and an elastic contact plate is installed on the circumferential side of the metal screw.

[0019] The above technical solution, through the contact plate mounting bracket structure, allows for corresponding installation and use.

[0020] The present invention is further configured such that the elastic abutment plate includes a bottom panel, and the inner sides of both ends of the bottom panel are provided with assembly screw holes. The bottom panel is sleeved on the periphery of the metal screw through the assembly screw holes. A U-shaped elastic sheet is fixedly connected to the inner side of the lower end of the bottom panel. An abutment spring is fixedly connected to the inner side of the U-shaped elastic sheet. An abutment rubber plate is adhered and fixedly connected to the lower end of the U-shaped elastic sheet.

[0021] The above technical solution utilizes an elastic contact plate structure, which allows for elastic resistance and downward pressure.

[0022] The present invention is further configured such that the abutting rubber plate is sleeved in the lower inner groove of the bottom panel.

[0023] The above technical solution allows the contact rubber plate to be positioned and moved by the groove on the lower inner side of the bottom panel.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. When the automotive lithium battery body is pressed down, it comes into contact with the elastic clamp, causing the elastic clamp to deform inward under external pressure. The outer shell of the automotive lithium battery tray effectively clamps and resists the automotive lithium battery body through the deformation of the elastic clamp.

[0026] 2. The bottom panel of the elastic contact plate has elastic force due to the U-shaped elastic sheet at the bottom. An abutment spring is fixed to the inside of the U-shaped elastic sheet. When the U-shaped elastic sheet deforms, it drives the abutment spring to deform, so that the abutment spring provides elastic abutment force to support the U-shaped elastic sheet. An abutment rubber plate is glued and fixed to the lower end of the U-shaped elastic sheet. The U-shaped elastic sheet drives the abutment rubber plate to elastically abut, so that it can elastically abut and press down on the car lithium battery body below, thereby ensuring that the car lithium battery can be placed stably.

[0037] Reference Figures 1-5 A mounting bracket for installing automotive lithium batteries includes an automotive lithium battery placement tray, an abutment mounting bracket, and a resilient abutment.

[0038] The contact plate mounting bracket is fixed to the outer walls of both ends of the automotive lithium battery placement tray. The contact plate mounting bracket can be placed on both sides of the automotive lithium battery placement tray. The elastic contact plate is installed and connected to the upper end of the contact plate mounting bracket. The elastic contact plate can be horizontally positioned above the automotive lithium battery placement tray through the contact plate mounting bracket, thereby connecting the automotive lithium battery placement tray and the elastic contact plate.

[0039] The automotive lithium battery placement tray includes an automotive lithium battery tray shell 3. An automotive lithium battery tray mounting cavity 5 is formed on the inner side of the upper end of the automotive lithium battery tray shell 3. The automotive lithium battery body can be placed within the area of ​​the automotive lithium battery tray mounting cavity 5. An elastic clamp 31 is fixedly connected to the inner wall of the automotive lithium battery tray shell 3 on the inner side of the automotive lithium battery tray mounting cavity 5. When the automotive lithium battery body is placed, the elastic clamp 31 is tilted in an inverted L-shape, so that the automotive lithium battery body contacts the elastic clamp 31 when pressed down. The contact causes the elastic clamp 31 to deform inward under external pressure. The car lithium battery tray shell 3 effectively clamps and abuts the car lithium battery body through the deformation of the elastic clamp 31. The two ends of the car lithium battery tray shell 3 are fixed with abutment plate mounting brackets. The abutment plate mounting brackets can be stably installed on the car lithium battery tray shell 3. The outer side of the abutment plate mounting bracket is fixed with a screw ear plate 4 at the corner of the car lithium battery tray shell 3. The car lithium battery tray shell 3 can be fixed in the designated position by screws through the screw ear plate 4.

[0040] The car lithium battery tray housing 3 and the screw ear plate 4 are fixedly connected by welding, so that they can be installed and fixed in place. The bottom ends of the car lithium battery tray housing 3 and the screw ear plate 4 are aligned so that there is no obstruction when placing them.

[0041] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The contact plate mounting bracket includes a welding end block 12. The inner wall of the welding end block 12 is fixed to the outer shell 3 of the automotive lithium battery tray. The welding end block 12 can be stably installed on the outer shell 3 of the automotive lithium battery tray. A connecting end rod 11 is fixed to the middle of the upper end of the welding end block 12. When the welding end block 12 is stably placed, it can drive the connecting end rod 11 to be stably placed. A metal screw 13 is fixed to the upper end of the connecting end rod 11. The connecting end rod 11 can drive the metal screw 13 to be stably placed. A locking nut 1 is rotatably connected to the circumferential thread of the metal screw 13. The locking nut 1 can rotate and rise and fall on the circumferential thread of the metal screw 13. An elastic contact plate is installed on the circumferential side of the metal screw 13. The locking nut 1 can move up and down on the metal screw 13 to abut the elastic contact plate, so that the elastic contact plate can stably press down on the automotive lithium battery body below.

[0042] There are four contact plate mounting brackets installed, and the contact plate mounting brackets are symmetrically installed on the car lithium battery tray housing 3. The contact plate mounting brackets can be placed and supported on both sides of the car lithium battery tray housing 3.

[0043] The elastic contact plate includes a bottom panel 2. Assembly screw holes 22 are provided on the inner sides of both ends of the bottom panel 2. The bottom panel 2 is sleeved onto the periphery of the metal screw 13 through the assembly screw holes 22, allowing the bottom panel 2 to be installed accordingly. A U-shaped elastic piece 23 is fixedly connected to the inner side of the lower end of the bottom panel 2. The bottom panel 2 has elastic force due to the U-shaped shape of the lower U-shaped elastic piece 23. An abutment spring 24 is fixedly connected to the inner side of the U-shaped elastic piece 23. When the U-shaped elastic piece 23 deforms, it causes the abutment spring 24 to deform, allowing the abutment spring 24 to provide elastic abutment force to support the U-shaped elastic piece 23. An abutment rubber plate 21 is adhered and fixedly connected to the lower end of the U-shaped elastic piece 23. The U-shaped elastic piece 23 then causes the abutment rubber plate 21 to elastically abut, allowing it to elastically press down on the lower automotive lithium battery body, thus ensuring the stable placement of the automotive lithium battery.

[0044] The abutting rubber plate 21 is fitted into the inner groove at the lower end of the bottom panel 2, thereby allowing it to be positioned and moved.

[0045] Working principle: The contact plate mounting bracket can be placed on both sides of the automotive lithium battery placement tray. The elastic contact plate can be horizontally positioned above the automotive lithium battery placement tray via the contact plate mounting bracket. Through the automotive lithium battery placement tray and the elastic contact plate, the automotive lithium battery tray shell 3 passes through the area of ​​the automotive lithium battery tray mounting cavity 5, allowing the automotive lithium battery body to be placed. When the automotive lithium battery body is pressed down, it contacts the elastic clamp 31, causing the elastic clamp 31 to deform inward under external pressure. The deformation of the automotive lithium battery tray shell 3 through the elastic clamp 31 effectively... The bottom panel 2 of the elastic contact plate clamps and abuts the main body of the automotive lithium battery. The U-shaped elastic sheet 23 at the bottom end has elastic force. An abutment spring 24 is fixed to the inner side of the U-shaped elastic sheet 23. When the U-shaped elastic sheet 23 deforms, it drives the abutment spring 24 to deform, so that the abutment spring 24 provides elastic abutment force to support the U-shaped elastic sheet 23. An abutment rubber plate 21 is glued and fixed to the lower end of the U-shaped elastic sheet 23. The U-shaped elastic sheet 23 drives the abutment rubber plate 21 to elastically abut, so that it can elastically abut and press down the automotive lithium battery body below, thereby ensuring that the automotive lithium battery can be placed stably.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
