Detailed implementation manners
[0019] The following are specific embodiments of the present utility model and in combination with the accompanying drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.
[0020] An electric vehicle frame with a battery shock absorption structure, as Figures 1 to 3 shown, includes a main frame body 1, and a battery box 2 for accommodating a battery is installed on the main frame body 1.
[0021] The battery box 2 includes an outer main body 21 and an inner main body 22. The inner main body 22 is arranged inside the outer main body 21, and the bottom of the outer main body 21 and the bottom of the inner main body 22 are arranged at intervals. A plurality of shock absorbers 3 are arranged between the bottom of the outer main body 21 and the bottom of the inner main body 22.
[0022] Specifically, the shock absorber 3 includes a positioning post one 31, a positioning post two 32 and a spring 33. A guiding slot 11 is opened on the positioning post two 32. The end of the positioning post one 31 is slidably arranged in the guiding slot 11. The spring 33 is sleeved on the outer side walls of the positioning post one 31 and the positioning post two 32. The positioning post one 31 is connected to the bottom of the inner main body 22, and the positioning post two 32 is connected to the bottom of the outer main body 21. The positioning post one 31 and the positioning post two 32 can cooperate to squeeze the spring 33. The end of the positioning post one 31 has a positioning flange one 6, and the end of the positioning post two 32 has a positioning flange two 7. One end of the spring 33 abuts against or is connected to the positioning flange one 6, and the other end of the spring 33 abuts against or is connected to the positioning flange two 7.
[0023] When the battery box 2 vibrates, the positioning post one 31 and the positioning post two 32 cooperate to squeeze the spring 33. The elastic restoring force of the spring 33 can weaken or offset the impact of the vibration force on the battery inside the battery box 2, thereby reducing the negative impact of the vibration on the battery box 2 and avoiding battery damage caused by vibration during the running of the electric vehicle.
[0024] The side walls of the outer main body 21 are spaced apart from the side walls of the inner main body 22. Shock-absorbing blocks 4 are provided between the side walls of the outer main body 21 and the side walls of the inner main body 22. Specifically, the shock-absorbing blocks 4 are provided on the outer side wall of the inner main body 22. A chute 8 is formed on the inner side wall of the outer main body 21. The shock-absorbing blocks 4 are adapted to the chute 8. It should be noted that the shock-absorbing blocks 4 are made of rubber material. The elastic characteristics of the rubber enable it to effectively absorb and disperse the vibration force, thereby reducing the impact of the vibration on the battery in the battery box 2.
[0025] The shock-absorbing blocks 4 are slidably arranged in the chute 8. Through the sliding cooperation of the shock-absorbing blocks 4 and the chute 8, the inner main body 22 and the outer main body 21 can be kept relatively stable. Moreover, when the battery box 2 is vibrated, the inner main body 22 slides relative to the outer main body 21. Since the shock-absorbing blocks 4 are made of rubber material, effective damping and buffering effects can be provided during the sliding process, thereby reducing the impact of the vibration on the battery inside the battery box 2.
[0026] At least two spaced-apart partition plates 9 are slidably arranged in the inner main body 22. By positioning the battery through the partition plates 9, the stability of the battery can be effectively ensured. Moreover, since the partition plates 9 are slidably arranged in the inner main body 22, different models and sizes of batteries can be placed.
[0027] Shock-absorbing pads 12 are provided on the side walls on both sides of the two partition plates 9. The shock-absorbing pads 12 are made of rubber or sponge. The shock-absorbing pads 12 can absorb and weaken the impact force, preventing the battery from directly contacting the partition plates 9 and causing damage.
[0028] Guide strips 10 are provided on the side walls on both sides of the inner main body 22. Guide grooves 5 adapted to the guide strips 10 are formed on the side walls on both sides of the partition plates 9. The guide strips 10 are slidably arranged in the guide grooves 5. Through the guiding cooperation of the guide strips 10 and the guide grooves 5, the relative stability between the partition plates 9 and the inner main body 22 can be ensured, and the stability during the movement of the partition plates 9 can also be ensured.
[0029] Positioning protrusions 13 are provided on the partition plates 9. A limiting pressure strip 14 for limiting the battery is detachably connected to the frame main body 1. It should be noted that the limiting pressure strip 14 is connected to the frame main body 1 by bolts. Positioning holes 15 are formed on the limiting pressure strip 14. The positioning protrusions 13 pass through the positioning holes 15. By limiting the positioning protrusions 13 through the positioning holes 15, the partition plates 9 are limited, ensuring the stable position of the partition plates 9.
[0030] The specific embodiments described herein are merely illustrative of the spirit of the present invention; those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
