[0021] The following details the embodiments of the present utility model, and the examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0022] Refer to Figures 1-5 It is an embodiment of the anti-power failure battery module of the present utility model,

[0023] It includes a battery case 1 and a battery cover 2. An installation plate 3 is provided on the upper end face of the battery case 1. A through hole 4 is provided in the middle part of the installation plate 3, and a positive electrode cap 5 is provided in the through hole 4. A threaded hole 6 is provided in the middle part of the battery cover 2, and a bolt 7 is provided in the middle of the threaded hole 6, and the diameter of the bolt 7 is smaller than the inner diameter of the cap of the positive electrode cap 5.

[0024] The battery cover 2 of this device covers the upper end face of the battery case 1. After the battery is installed in the battery case 1, the positive electrode of the battery will abut against the positive electrode cap 5 to complete power-on. However, if the positive electrode of the battery cannot touch the positive electrode cap 5, the positive electrode cap 5 of this device is movably arranged in the through hole 4. At this time, the bolt 7 on the battery cover 2 can be rotated, and the rotating bolt 7 will rise or fall relative to the battery cover 2. The downward direction is the direction where the positive electrode cap 5 is located. When the battery shakes in the battery case 1, the bolt 7 can be pressed on the positive electrode cap 5, and then the positive electrode cap 5 presses on the positive electrode of the battery to stabilize the battery and prevent power-off at the same time.

[0025] Refer to Figure 5 At the same time, a battery seat 11 for installing a negative electrode spring 12 is also provided on the battery case 1 of this device; the battery cover 2 is provided at the upper end of the battery case 1, and the battery seat 11 is provided at the lower end of the battery case 1; after the battery is placed in the battery case 1, the positive electrode of the battery contacts the positive electrode cap 5 on the battery cover 2, and the negative electrode of the battery contacts the negative electrode spring 12 on the battery seat 11 to complete power-on.

[0026] When the rotating bolt 7 presses on the positive electrode cap 5 in this device, the positive electrode cap 5 contacts the positive electrode of the battery, and at the same time, the positive electrode cap 5 will push the battery to move. At this time, the moving direction of the battery is the direction of the negative electrode spring 12. At this time, it can be ensured that the negative electrode of the battery presses on the negative electrode spring 12. Cooperating with the positive electrode cap 5 pressing on the positive electrode of the battery, it can ensure the stable power supply of the battery.

[0027] When the device shakes violently, the structure of this device can ensure that the battery will not lose power.

[0028] The positive electrode cap 5 includes a cap edge 51 provided on the upper end face of the installation plate 3, a cap cylinder 52 extending into the through hole 4, and a positive electrode plate 53 provided on the lower end face of the cap cylinder 52.

[0029] The cap edge 51 of this device can place the positive electrode cap 5 on the upper end face of the installation plate 3. The cap cylinder 52 can extend into the through hole 4 to contact the positive electrode of the battery, and the positive electrode plate 53 mainly provides a larger contact area to facilitate contact with the positive electrode of the battery.

[0030] The positive electrode cap 5 is integrally formed, and the material is one of lithium cobaltate, lithium manganate, and ternary materials.

[0031] Lithium cobaltate has a relatively high energy density and stability, but its price is relatively high; lithium manganate is relatively inexpensive, but due to the instability of the cathode structure, its service life is relatively short; ternary materials have a high energy density, good high-temperature performance, and high cost; one of the three types is selected according to the cost for this device.

[0032] A groove is also provided on the upper end surface of the mounting plate 3, and a battery connector 8 is provided in the groove.

[0033] The function of the groove is to install the battery connector 8, which can make the battery cover 2 thinner and reduce the material cost.

[0034] The bolt 7 includes a threaded post 71 with a flat lower end surface and a cylindrical nut 72 provided on the upper end surface of the threaded post 71. An operation groove 73 is provided on the upper end surface of the nut 72.

[0035] The bolt 7 of this device is set like this mainly to enable the staff to adjust the positive electrode cap 5. Generally speaking, the tools carried by maintenance staff will include a flat-head screwdriver. The nut 72 is set to be cylindrical for convenient processing, and at the same time, the operation groove 73 can also be rotated using a flat-head screwdriver.

[0036] Mounting rings 9 with internal threads are also provided on the upper end surface of the mounting plate 3 on both sides of the through hole 4. Mounting holes 10 with internal threads are provided in the battery cover 2, and the diameter of the mounting hole 10 is the same as that of the mounting ring 9.

[0037] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
