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.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A battery pack with a protective structure comprises a lower shell 1, an upper shell 11 and a battery body 12 installed between the lower shell 1 and the upper shell 11, the upper shell 11 and the lower shell 1 are in contact and connected together, a damper 2 is fixedly connected to the surface of the lower shell 1, a shock-absorbing spring 21 is fixedly connected to the surface of the lower shell 1, a mounting platform 22 is fixedly connected to the top of the shock-absorbing spring 21, a telescopic end of the damper 2 is fixedly connected to the lower surface of the battery body 12, the battery body 12 is fixedly mounted on the upper surface of the mounting platform 22, and a protective pad 23 is fixedly connected to the lower surface of the upper shell 11. The protective mechanism can reduce the vibration of the battery body 12 after the lower shell 1 and the upper shell 11 are impacted, and sufficient impact space is reserved between the lower shell 1 and the upper shell 11 to avoid the lower shell 1 and the upper shell 11 being impacted, causing damage to the battery body 12, thereby improving the safety of the battery body 12.

[0024] Furthermore, a mounting mechanism is provided on the lower shell 1 and the upper shell 11, and the mounting mechanism includes a clamping block 3, which is fixedly connected to the lower surface of the lower shell 1, a return spring 32 is fixedly connected to the surface of the lower shell 1, a connecting rod 33 is fixedly connected to the surface of the return spring 32, a clamping rod 31 is fixedly connected to the surface of the connecting rod 33, and the clamping rod 31 is slidably connected to the surface of the lower shell 1. The mounting mechanism avoids the use of bolts for installation, thereby avoiding the use of tools for installation, thereby improving the installation efficiency of the battery body 12 between the lower shell 1 and the upper shell 11.

[0025] Furthermore, a rectangular groove is provided on the upper surface of the lower shell 1, and a rectangular groove is provided on the lower surface of the upper shell 11. The rectangular grooves of the lower shell 1 and the upper shell 11 are combined to form a storage bin, and the battery body 12 is fixedly mounted on the storage bin between the lower shell 1 and the upper shell 11. The space of the storage bin is relatively large, and the battery body 12 can be easily installed in the storage bin between the lower shell 1 and the upper shell 11, so that the storage bins of the lower shell 1 and the upper shell 11 reserve space for the battery body 12 to be hit, thereby improving the safety of the battery body 12.

[0026] Furthermore, the damper 2 and the shock-absorbing spring 21 are in multiple groups, and the damper 2 and the shock-absorbing spring 21 are distributed in an array on the rectangular groove of the lower shell 1. The damper 2 and the shock-absorbing spring 21 support the position of the battery body 12 in the middle position of the storage compartment of the lower shell 1 and the upper shell 11 through the mounting platform 22. The damper 2 and the shock-absorbing spring 21 cooperate with each other to reduce the vibration amplitude of the battery body 12, thereby reducing the chance of damage to the battery body 12.

[0027] Furthermore, the protective pad 23 is fixedly connected to the rectangular groove of the upper shell 11, and the protective pad 23 is in contact with the upper surface of the battery body 12. The protective pad 23 is at the top of the battery body 12, preventing the battery body 12 from being damaged by impact on the storage grooves of the lower shell 1 and the upper shell 11.

[0028] Furthermore, a card slot is provided on the upper surface of the lower housing 1, and the card block 3 is in the shape of a "mouth" as a whole. The card block 3 is connected to the card slot of the lower housing 1 by card engagement, and the card block 3 positions the upper housing 11 on the upper surface of the lower housing 1. This facilitates the installation between the upper housing 11 and the lower housing 1.

[0029] Furthermore, a circular groove is provided on the surface of the lower shell 1, and the clamping rod 31 is fixedly connected to the two ends of the connecting rod 33. The clamping rod 31 drives the connecting rod 33 to slide on the surface of the lower shell 1. A circular hole is provided on the surface of the clamping block 3. The clamping rod 31 passes through the circular hole of the clamping block 3. The elastic force of the reset spring 32 acts on the clamping rod 31 through the connecting rod 33. The clamping rod 31 limits the upper shell 11 to the upper surface of the lower shell 1 through the clamping block 3, thereby completing the installation between the lower shell 1 and the upper shell 11.

[0030] Working principle: expand the space of the storage bin between the lower shell 1 and the upper shell 11, fix the battery body 12 on the upper surface of the mounting platform 22, and install the battery body 12 at the center of the storage bin through the mounting platform 22 with the damper 2 and the shock-absorbing spring 21. At the same time, the damper 2 and the shock-absorbing spring 21 cooperate with each other to reduce the shock of the battery body 12. The protective pad 23 connected to the upper surface of the battery body 12 can protect the battery body 12 from impact. Due to the position of the battery body 12 between the lower shell 1 and the upper shell 11, after the outer surfaces of the lower shell 1 and the upper shell 11 are hit, the battery body 12 can be in a position to increase the safety of the battery body 12.

[0031] When the lower shell 1 and the upper shell 11 need to be installed, the connecting rod 33 is pulled to make the clamping rod 31 slide on the circular groove of the lower shell 1, and the reset spring 32 is pulled and deformed. At this time, the clamping block 3 is engaged and connected to the clamping groove of the lower shell 1 to position the upper shell 11 on the surface of the lower shell 1. At this time, the connecting rod 33 is released, and the clamping rod 31 on the connecting rod 33 slides on the lower shell 1 to the circular hole passing through the clamping block 3 under the elastic force of the reset spring 32. The clamping rod 31 fixes the upper shell 11 and the lower shell 1 together through the clamping block 3, completing the fixed installation between the lower shell 1 and the upper shell 11.
