[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a battery tray rear support frame, including a battery body 1, a support frame 2 for supporting and fixing the battery body 1 is arranged at the bottom of the battery body 1, a buffer mechanism is arranged at the bottom of the support frame 2, a groove 3 is opened at the top of the support frame 2, the size of the groove 3 is larger than the size of the battery body 1, so that battery bodies 1 of different sizes can be placed and installed, and the adaptability is good. The bottom of the battery body 1 and the top of the groove 3 fit together, and the bottom of the inner wall of the groove 3 is fixedly connected with a vertically arranged positioning rod 4, which is inserted into the bottom inner wall of the battery body 1. The number of positioning rods 4 is set to multiple, and multiple positioning rods 4 are stacked and arranged at the inner bottom of the groove 3. The positioning rods improve the installation accuracy of the battery body 1, so that the battery body 1 is more stable after installation. A fixing mechanism is arranged inside the support frame 2, and the fixing mechanism includes a rotating shaft 6, which passes through and is rotatably installed on the inner wall of the support frame 2.

[0031] Reference Figure 2 - Figure 3 The fixing mechanism also includes a knob 5, and the circumferential surface of the knob 5 is provided with an anti-skid key pattern for increasing the friction between the palm and the knob 5, reducing the possibility of slipping, and facilitating use. The knob 5 is fixedly mounted on the front end of the rotating shaft 6 located outside the support frame 2, and the knob 5 drives the rotating shaft 6 to rotate. The rear end of the rotating shaft 6 located inside the support frame 2 is fixedly connected with a threaded rod 7, and the rotating shaft 6 drives the threaded rod 7 to rotate. The fixing mechanism also includes a sliding rod 8, and the sliding rod 8 is fixedly mounted on the inner wall of the support frame 2. The number of sliding rods 8 is two groups, and the two groups of sliding rods 8 are symmetrically arranged on the left and right sides of the threaded rod 7. The two groups of sliding rods 8 are inclined and have the same inclination angle. The two groups of sliding rods 8 are V-shaped and arranged inside the support frame 2. The fixing mechanism also includes a side slider 9 and a middle slider 10. The side slider 9 is slidably mounted on the circumferential surface of the sliding rod 8. The sliding direction of the side slider 9 is to slide along the axial direction of the sliding rod 8. The middle slider 10 is threadedly mounted on the circumferential surface of the threaded rod 7. The rotation of the threaded rod 7 causes the middle slider 10 to move in the front and rear directions under the action of the thread.

[0032] Reference Figure 3The fixing mechanism also includes a control rod 11, the number of which is set to two groups, and the two groups of control rods 11 are fixedly mounted on the left and right sides of the middle slider 10, respectively. The control rod 11 extends in the left and right directions, and the side slider 9 slides on the circumferential surface of the control rod 11. The displacement of the middle slider 10 in the front and rear directions synchronously drives the control rod 11 to move forward and backward, and the control rod 11 cooperates with the slide bar 8 to make the side slider 9 slide in the axial direction of the slide bar 8. The fixing mechanism also includes a pressure block 12, which is fixedly mounted on the top of the side slider 9, and the pressure block 12 penetrates and slides on the inner wall of the support frame 2. The number of the pressure blocks 12 is set to two groups, and an anti-skid groove is provided on one side of the two groups of pressure blocks 12 that are close to each other. The two groups of pressure blocks 12 that are close to each other contact with the surface of the battery body 1 through the anti-skid groove and apply a pre-tightening force, thereby improving the stability of the clamping and fixing of the battery body 1, improving the firmness of the installation of the battery body 1, and preventing the battery body 1 from accidentally falling and being damaged.

[0033] Reference Figure 2 - Figure 4 The buffer mechanism includes a sleeve 13 and a buffer rod 14. The buffer rod 14 penetrates and the piston is installed on the inner wall of the sleeve 13. The buffer rod 14 is vertically arranged. The top of the buffer rod 14 is fixedly connected to the bottom of the support frame 2. The bottom of the buffer rod 14 is elastically connected to the bottom of the inner wall of the sleeve 13 through a spring 15. The spring 15 applies an upward elastic force to the buffer rod 14. The surface of the sleeve 13 is provided with air holes 16 that can facilitate the exchange of gas inside and outside the sleeve 13. The hole diameter of the air hole 16 is small. The air hole 16 can be a round hole or a square hole. The number of the air holes 16 can be set to multiple, and the air holes 16 can be set as needed. The buffer mechanism also includes a support base 17, which is fixedly mounted on the bottom of the sleeve 13 to support and stabilize the base. The bottom of the support base 17 is fixedly connected with a mounting plate 18 made of rubber material with good elasticity. In some applications such as automobiles, a part of the vibration energy can be absorbed to reduce the damage to the battery body 1 caused by the vibration energy during use. The surface of the mounting plate 18 is provided with a mounting hole 19, and the mounting plate 18 can be fixed to other platform surfaces by fastening bolts, so that the support base 17 has good stability during work and improves safety during use.

[0034] Working principle: When installing and using the support frame 2, the battery body 1 is placed inside the groove 3, and the battery body 1 is aligned with the positioning rod 4 and the battery body 1 is pressed downward, so that the positioning rod 4 is inserted into the inner wall of the bottom of the battery body 1, and then the knob 5 is turned. The rotation of the knob 5 drives the rotating shaft 6 to rotate, and the rotation of the rotating shaft 6 drives the threaded rod 7 to rotate. The rotation of the threaded rod 7 drives the middle slider 10 to make a forward and backward linear displacement in the axial direction of the threaded rod 7, and then drives the control rod 11 to move forward. The displacement of the control rod 11 drives the side slider 9 to move forward. Since the slide bar 8 will guide the displacement direction of the side slider 9, the two groups of slide bars 8 will also approach each other while the slide bar 8 moves forward, thereby driving the two groups of pressing blocks 12 to approach each other, and then the surface of the battery body 1 is attached and squeezed, so that the battery body 1 is more firmly fixed on the top of the support frame 2.

[0035] By setting a buffer mechanism, when the battery body 1 vibrates during use, the battery body 1 will squeeze the buffer rod 14 downward, causing the buffer rod 14 to move downward relative to the sleeve 13. When the buffer rod 14 moves, it overcomes the elastic force of the spring 15 and moves downward. At the same time, the downward movement of the buffer rod 14 squeezes the gas inside the sleeve 13, thereby increasing the gas pressure inside the sleeve 13, so that the gas inside the sleeve 13 is squeezed from the pores 16 to the outside of the sleeve 13. Since the aperture of the pores 16 is small, it can hinder and reduce the speed of the air flow, so that the speed of the buffer rod 14 when moving is slowed down, thereby playing a buffering and deceleration role for the battery body 1 above the support frame 2, and reducing the damage to the battery body 1 caused by the vibration energy.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
