[0022] 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.

[0023] See also Figure 1-6 , an embodiment provided by the utility model:

[0024] A limiting frame for installing a lithium battery comprises a protective frame 1, a placing frame 11 is arranged on the inner surface of the protective frame 1, an upper cover 12 is installed on the surface of the protective frame 1, a lithium battery is installed on the placing frame 11, a shielding mechanism is arranged on the surface of the protective frame 1, the shielding mechanism comprises a fixing rod 2, the fixing rod 2 is fixedly connected to the inner surface of the protective frame 1, a movable block 21 is slidably connected to the surface of the fixing rod 2, a shielding plate 22 is fixedly connected to the surface of the movable block 21, a connecting rod 23 is fixedly connected to the bottom of the shielding plate 22, a cylinder 24 is fixedly connected to the inner surface of the protective frame 1, and the connecting rod 23 is fixedly connected to the piston rod of the cylinder 24, and the shielding mechanism can shield the heat dissipation holes on the protective frame 1, thereby preventing cold air from entering the interior of the protective frame 1, preventing the lithium battery from being overly hot, and improving the service life of the lithium battery.

[0025] Furthermore, a shock absorbing mechanism is arranged on the surface of the protective frame 1, and the shock absorbing mechanism includes a movable rod 3, one end of the movable rod 3 is rotatably connected to the inner surface of the protective frame 1, and the other end of the movable rod 3 is rotatably connected to the placement frame 11, and a shock absorbing spring 31 is fixedly connected to the inner surface of the protective frame 1, and a damper 32 is fixedly connected to the inner surface of the protective frame 1, and the damper is telescopic, and the telescopic end of the damper 32 is fixedly connected to a guide block 33, and a guide rod 34 is fixedly connected to the surface of the placement frame 11, and the guide rod 34 is slidably connected to the guide block 33. The lithium battery will vibrate during use, and the damper 32, shock absorbing spring 31 and movable rod 3 of the shock absorbing mechanism are symmetrically distributed on both sides of 11. The shock absorbing mechanism can reduce the vibration amplitude of the lithium battery, reduce the impact force of the lithium battery, and effectively protect the lithium battery.

[0026] Furthermore, heat dissipation holes are opened on the surfaces of the protective frame 1 and the placement frame 11, and heat dissipation holes are opened on the surface of the shielding plate 22. The heat dissipation holes of the shielding plate 22 and the heat dissipation holes of the protective frame 1 and the placement frame 11 are on the same horizontal line. During the heat dissipation process, cooling air can pass through the heat dissipation holes of the shielding plate 22 and the heat dissipation holes of the protective frame 1 and the placement frame 11, thereby cooling the lithium batteries.

[0027] Furthermore, the baffle plate 22 is in contact with and connected to the inner surface of the protective frame 1, and slides on the inner surface of the protective frame 1 through the movable block 21. During the sliding process, the position of the heat dissipation holes of the baffle plate 22 is changed so that the heat dissipation holes of the baffle plate 22 and the heat dissipation holes of the protective frame 1 are misaligned. At this time, the baffle plate 22 blocks the heat dissipation holes of the protective frame 1, thereby ensuring the temperature of the lithium battery inside the protective frame 1.

[0028] Furthermore, there are two groups of baffles 22, and the two groups of baffles 22 are fixedly connected to the two ends of the connecting rod 23 respectively. The connecting rod 23 slides at the bottom of the protective frame 1 through the piston rod of the cylinder 24. The connecting rod 23 simultaneously drives the two groups of baffles 22 to slide on the inner surface of the protective frame 1, so that the two groups of baffles 22 can simultaneously block the heat dissipation holes on both sides of the protective frame 1.

[0029] Furthermore, the movable rod 3 is in an inclined state, and the protective frame 1 supports the placement frame 11 through the movable rod 3. When the placement frame 11 vibrates, the movable rod 3 will rotate between the protective frame 1 and the placement frame 11. The end of the shock-absorbing spring 31 away from the protective frame 1 is fixedly connected to the placement frame 11, and the elastic force of the protective frame 1 acts on the placement frame 11 through the shock-absorbing spring 31.

[0030] Furthermore, a "T"-shaped guide groove is opened on the surface of the guide block 33, and the guide rod 34 is in a "T" shape. The guide rod 34 slides on the guide groove of the guide block 33, and the placement rack 11 slides on the surface of the guide block 33 through the guide rod 34. The placement rack 11 passes through the guide block 33 and the guide rod 34, so that during the vibration of the placement rack 11, the placement rack 11 and the telescopic end of the damper 32 are always kept connected, and the damper 32 cooperates with the shock-absorbing spring 31 to reduce the vibration amplitude of the placement rack 11 on the protective frame 1.

[0031] Working principle: the piston rod of the cylinder 24 pushes the connecting rod 23 to slide on the inner surface of the protective frame 1, and the baffle plate 22 can slide on the fixed rod 2 through the movable block 21. At this time, the connecting rod 23 can simultaneously drive the two sets of baffle plates 22 to slide on the surface of the protective frame 1. During the sliding process of the baffle plates 22, the heat dissipation holes of the baffle plates 22 and the heat dissipation holes of the protective frame 1 are misaligned. At this time, the baffle plates 22 block the heat dissipation holes of the protective frame 1, preventing the cold air outside the protective frame 1 from continuing to flow into the inside of the protective frame 1, and preventing the lithium battery from being in an excessively low temperature environment.

[0032] The protective frame 1 supports the placement frame 11 through the movable rod 3. The placement frame 11 will cause the movable rod 3 to rotate during the vibration process, and the placement frame 11 drives the guide rod 34 to slide on the guide groove of the guide block 33. The telescopic end of the damper 32 is connected to the placement frame 11 through the guide block 33 and the guide rod 34. The damper 32 and the shock-absorbing spring 31 cooperate with each other to dampen the shock of the placement frame 11, thereby reducing the vibration amplitude of the lithium battery, reducing the impact force of the lithium battery, and effectively protecting the lithium battery.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
