[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0035] Reference Figure 1-9 The battery protection device of an electric tricycle includes a protective shell 1 with an upper opening; the protective shell 1 is in a rectangular shape, and the internal space is slightly larger than the size of the battery; at the same time, a mounting plate 2 is provided under the protective shell 1 for fixing it on the frame.

[0036] like Figure 1 , 2 As shown; the size of the mounting plate 2 is larger than the size of the protective shell 1, forming an outwardly expanded edge; at the same time, shock absorbing members 3 are provided at the four corners of the mounting plate 2 to reduce the vibration effect on the battery when the vehicle is running.

[0037] At the same time, a plurality of rubber strips 4 are vertically arranged on the inner side wall of the protective shell 1 .

[0038] like Figure 5 , 6 As shown, the rubber strip 4 protrudes inward and contacts the outer wall of the battery; thus, when vibration or shaking occurs, the rubber property can reduce the impact on the battery and provide better protection.

[0039] Moreover, compared with structures such as springs and damping shafts, this structure has lower costs and is more reliable and stable.

[0040] Furthermore, a rubber grid 5 is placed on the inner bottom surface of the protective shell 1 .

[0041] like Figure 6 ,7 , 8; the rubber grid 5 at the bottom provides shock absorption and protection for the bottom of the battery.

[0042] In some embodiments, the shock absorbing member 3 includes a bolt 31 that passes through the mounting plate 2 , and a spring 32 and a washer 33 are sleeved on the outside of the bolt 31 .

[0043] like Figure 1-6 As shown; the mounting plate 2 is provided with a through-hole 21 and a strip hole 22 for the bolt 31 to pass through, and can be installed at an optional position; as shown in the attached Figure 1 In the embodiment, the shock absorbing member 3 is installed at the position where the circular hole 21 is penetrated.

[0044] In some embodiments, crisscross reinforcing ribs 6 are provided below the mounting plate 2 .

[0045] like Figure 4 As shown, the multiple reinforcing ribs 6 not only increase the strength of the mounting plate 2, but also reduce the contact area between the mounting plate 2 and the frame, further reducing the transmission of vibration and better protecting the battery.

[0046] In some embodiments, a triangular rib 11 is disposed on the outer side of the protective shell 1 .

[0047] like Figure 1 , 2 As shown; the triangular rib 11 connecting the mounting plate 2 and the protective shell 1 significantly improves the overall strength and has a better protective effect.

[0048] Furthermore, a waistline ring 12 is arranged around the outer side of the protective shell 1 to further enhance the strength and reliability.

[0049] In some embodiments, a top cover 7 is disposed above the protective shell 1 .

[0050] The top cover 7 can be fixed by means of buckles, fixing bolts or the like.

[0051] Furthermore, a lead-in opening 72 with a cover 71 is provided on one side of the top cover 7 .

[0052] In some embodiments, a tightening screw 8 is disposed on the outer side of the protective shell 1 .

[0053] As shown in the figure, by adjusting the pushing depth of the tightening screw 8 and cooperating with the rubber strip 4, the moving space of the battery is adjusted.

[0054] Furthermore, an inner threaded barrel 81 extending outward is provided on the outer side of the protective shell 1 so that the tightening screw 8 has a larger connection surface, which is more stable and reliable.

[0055] In some embodiments, a lower through hole 9 is formed on the mounting plate 2 .

[0056] like Figure 4 , 6 , 8, and 9; the lower through holes 9 arranged in the array do not interfere with the rubber grid 5, and can be ventilated at the bottom and discharge debris and water entering the interior.

[0057] Furthermore, the inner diameter of the lower through hole 9 extends and contracts downward, that is, a configuration is formed in which the upper opening is large and the lower opening is small. While ventilation and impurity discharge are possible, splashing of sewage from the ground can be reduced.

[0058] When the utility model is used, the whole is installed on the vehicle frame through the shock absorbing member 3; after the storage battery is placed, the top cover 7 and the cover 71 are covered; during the use of the vehicle, the various components cooperate to provide reliable and effective protection for the storage battery.

[0059] In the utility model, the mounting plate 2 cooperates with the shock-absorbing member 3 to reduce the vibration effect on the battery when the vehicle is running; the rubber strip 4 is vertically arranged on the inner wall of the protective shell 1 and protrudes inward, and touches the battery, using the rubber characteristics to reduce the impact of vibration and shaking on the battery, providing better protection; and, the cost is lower, and the reliability and stability are more effective; a rubber grid 5 is placed on the inner bottom surface to provide a protective effect on the bottom of the battery; criss-cross reinforcement ribs 6 are arranged to further reduce the transmission of vibration while improving the strength of the mounting plate 2, and better protect the battery; triangular ribs 11 and waistline rings 12 are arranged on the outer side of the protective shell 1, which significantly improve the overall strength and have a better protective effect; a lower through hole 9 is opened to ventilate the lower part and discharge debris and water entering the interior; the inner diameter of the lower through hole 9 extends and contracts downward to reduce the occurrence of ground sewage splashing.
