[Technical Field]
[0001] This invention relates to a battery box with a buffer function for an electric motor vehicle, particularly a battery box with a buffer function for an electric motor vehicle that can buffer the impact force of a collision on the battery. [Previous Technology]
[0002] In view of the intensified global warming caused by climate change, the global demand for environmental sustainability and energy conservation and carbon reduction continues to increase, which has accelerated the development of motor vehicles towards electric drive. By installing batteries in motor vehicles to provide the electrical energy required for the operation of electric drive motors, the problem of air pollution can be solved and the benefits of net-zero carbon emissions can be achieved.
[0003] In order to securely house the battery in an electric motor vehicle, the vehicle body is typically equipped with a battery box, which includes an outer shell and a top cover. The outer shell can accommodate the battery of the electric motor vehicle, and the top cover is detachably fitted onto the outer shell to prevent the battery from being exposed, thereby achieving the functions of protection and waterproofing, so that the battery can stably provide the electric motor vehicle with the electrical energy required for driving.
[0004] However, since there is often a gap between the battery and the casing and the top cover to facilitate disassembly and assembly, when the user drives the electric motor vehicle on different terrains, once a bumpy road is encountered, the battery of the electric motor vehicle will continuously collide with the casing and the top cover, which will damage the battery over time and shorten its lifespan. [Summary of the Invention]
[0005] The main purpose of this invention is to provide a battery box with a buffer function for electric motor vehicles, thereby improving the problem that the battery will collide with the inner wall of the battery box when the electric motor vehicle is driving on bumpy roads, which will cause damage to the battery.
[0006] To achieve the aforementioned objective, the present invention provides a battery box with a buffer function for an electric motor vehicle, which can be disposed in the body of an electric motor vehicle and can assemble at least one battery. The battery box with a buffer function includes: a shell having a body and a plurality of elastic members, the interior of the body forming an upward-opening accommodating space for accommodating the battery, and the sidewall of the body having an annular set of portions, the plurality of elastic members being spaced apart from the set of portions, the plurality of elastic members being partially assembled in the accommodating space of the body and abutting against the battery; and a top cover detachably mounted on the top of the body, the top cover having a cover body and a plurality of buffer pieces, the cover body forming a plurality of spaced-apart mounting portions, and the plurality of buffer pieces being respectively disposed at the bottom of the plurality of mounting portions and abutting against the top of the battery.
[0007] The battery box with buffer function of the electric motor vehicle of this invention can buffer the impact force of the battery when it is hit by a collision. The battery box with buffer function of the electric motor vehicle of this invention allows the user to ride on bumpy roads. Through the multiple elastic members and multiple buffer sheets made of elastic materials such as rubber located between the battery and the mounting parts of the main body and the cover, the peripheral wall and top of the battery are abutted and positioned to reduce the vibration of the battery. At the same time, it can buffer the impact force generated by the collision between the battery and the mounting parts of the main body and the cover, thereby reducing the damage to the battery.
Implementation Method
[0008] Please refer to Figures 1 to 3, which show a preferred embodiment of the battery box 1 with a buffer function for an electric motor vehicle of the present invention. It can be disposed in the body 2 of an electric motor vehicle and can assemble at least one battery 3. The battery box 1 with a buffer function includes a shell 10 and a top cover 20.
[0009] As shown in Figures 3, 4 and 6, the outer casing 10 has a body 11 and a plurality of elastic members 12. The interior of the body 11 forms an upward-facing accommodating space 111, which can accommodate the battery 3. The sidewall of the body 11 has an annular set of portions 112. The plurality of elastic members 12 can be spaced apart on the set of portions 112. The plurality of elastic members 12 can be partially assembled in the accommodating space 111 of the body 11 and abut against the battery 3.
[0010] As shown in Figures 3, 4, 6 and 7, the assembly part 112 of the body 11 has a plurality of through holes 113. The assembly part 112 has a plurality of snap-fit blocks 114 protruding downward from the upper edge of the plurality of through holes 113 and a plurality of stop blocks 115 protruding upward from the lower edge of the plurality of through holes 113. Each elastic member 12 has a snap-fit groove 121 and a stop groove 122 arranged opposite to each other, and an abutting part 123 located on one side of the snap-fit groove 121 and the stop groove 122. The plurality of elastic members 12 are respectively passed through the plurality of through holes 113. The snap-fit groove 121 can be engaged with the snap-fit block 114. The stop groove 122 can abut against the stop block 115. The abutting part 123 of the plurality of elastic members 12 can assemble the accommodating space 111 of the body 11 and abut against the battery 3.
[0011] As shown in Figures 3 to 5, the top cover 20 is detachably mounted on the top of the body 11. The top cover 20 has a cover body 21 and a plurality of buffer pieces 22. The cover body 21 forms a plurality of assembly parts 211 arranged at intervals, and the plurality of buffer pieces 22 are respectively disposed at the bottom of the plurality of assembly parts 211 and abut against the top of the battery 3.
[0012] As shown in Figures 3 to 5, at least one fastening hole 212 is formed at the bottom of each assembly part 211, and at least one fastening part 221 extending upward is formed at the top of each buffer piece 22. The fastening part 221 can be assembled and fastened to the fastening hole 212.
[0013] As shown in Figures 3 to 5, each assembly part 211 has an upward-facing assembly space 213 inside. The assembly space 213 is connected to the snap-fit hole 212 of the assembly part 211. Each assembly part 211 has at least one engagement groove 214 on the inner side wall of the assembly space 213. The upper cover 20 includes a plurality of decorative covers 24. The plurality of decorative covers 24 are respectively provided on the plurality of assembly parts 211 and the corresponding closed positions of the assembly space 213. Each decorative cover 24 has at least one downward-extending engagement part 241 at its end edge. The engagement part 241 can be snapped into the engagement groove 214 of the assembly part 211.
[0014] As shown in Figures 3, 4 and 6, the upper cover 20 includes a reinforcing plate 23, which is disposed on the cover body 21.
[0015] As shown in Figures 4, 6 and 7, when assembling the battery into the battery box 1 with a buffer function of the electric motor vehicle of this invention, the user can first place the battery 3 in the receiving space 111 of the main body 11. Since the protruding length of the abutting part 123 of the plurality of elastic members 12 toward the receiving space 111 of the main body 11 is greater than the fitting gap between the inner wall of the main body 11 and the battery 3, and the plurality of elastic members 12 are made of elastic materials such as rubber, the end of the abutting part 123 can be compressed to tightly abut against the side wall of the battery 3, thereby positioning the peripheral wall of the battery 3 and providing a shock-absorbing effect between the battery 3 and the inner wall of the main body 11.
[0016] Furthermore, as shown in Figures 4 and 5, the user can further close the top cover 20 onto the top of the main body 11. Since the top surface of the plurality of buffer pieces 22 is attached to the bottom of the plurality of mounting parts 211, and the thickness of the plurality of buffer pieces 22 is greater than the fitting gap between the mounting parts 211 of the cover 21 and the battery 3, and the plurality of buffer pieces 22 are also made of elastic materials such as rubber, the bottom surface of the plurality of buffer pieces 22 can be compressed to tightly abut against the top of the battery 3, so that the gap between the bottom of the plurality of mounting parts 211 and the battery 3 is filled, thereby positioning the battery 3 to prevent it from shaking up and down while providing cushioning protection.
[0017] Therefore, as shown in Figures 4 to 6, the plurality of elastic members 12 and the plurality of buffer pieces 22 have compressible and resilient material properties to provide good cushioning force, and are respectively located between the battery 3 and the assembly part 211 of the body 11 and the cover 21. When the user drives on a bumpy road, the peripheral wall and top of the battery 3 are abutted and positioned to reduce the vibration of the battery 3, and at the same time, they can buffer the impact force generated by the collision between the battery 3 and the inner wall of the body 11 and the assembly part of the cover 21, thereby reducing the damage to the battery 3.
[0018] Furthermore, as shown in Figures 4 to 6, the plurality of decorative covers 24 can cover the assembly space 213 of the plurality of assembly parts 211 to prevent the fastening parts 221 of the plurality of buffer pieces 22 and the fastening holes 212 of the plurality of assembly parts 211 from being exposed, ensuring that dust or rainwater is not easily penetrated into the body 11 during outdoor riding and thus causing damage to the battery 3, while making the appearance of the cover 21 more aesthetically pleasing; in addition, the reinforcing plate 23 can enhance the structural strength of the cover 21 and prevent the cover 21 from deforming after colliding with the battery 3, so as to ensure that the cover 21 can continuously provide positioning and cushioning for the battery 3.
