Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorption devices, and particularly relates to a battery shock absorption and buffering device for new energy construction machinery. Background Art

[0002] New energy, also known as unconventional energy, refers to various forms of energy other than traditional energy. As a special type of new energy, new energy batteries are applied to new energy vehicles. However, during the use of new energy vehicles, especially during driving, various unexpected situations may be encountered, such as uneven roads, collision accidents, etc. These may all impact the new energy battery, causing damage to it and even triggering safety accidents. In existing new energy vehicles, the new energy battery is fixed on a battery bracket, and then the battery bracket is fixed in the vehicle body. For some fixed points between the battery bracket and the vehicle body, shock pads are installed, or the overall battery bracket is modified to add a shock absorption mechanism to reduce the vibration and impact received by the battery box.

[0003] The vibration intensity in the working conditions of construction machinery vehicles is much greater than that of ordinary passenger cars and commercial vehicles. The existing battery bracket design for new energy construction machinery vehicles only considers how to fix the new energy battery and lacks consideration of shock absorption and buffering capabilities. Relying solely on shock pads cannot effectively avoid damage to the battery caused by high-vibration working conditions. At the same time, there is no effective buffer device for the forward displacement of the new energy battery due to inertia when the vehicle brakes, which is likely to damage the battery. And the method of modifying the overall battery bracket to add a shock absorption mechanism requires re-opening the mold for the battery bracket and adding a new production line, resulting in a large cost investment. How to effectively provide a low-cost battery pack shock absorption and buffering device, avoid the high cost of re-opening the mold design for the battery bracket in the battery shock absorption bracket solution, effectively improve the stability of the battery system of new energy construction machinery vehicles while reducing costs and increasing efficiency has become an urgent problem to be solved.

[0028] Embodiment 1

[0029] Referring to the attached Figure 1-2 , a battery shock absorption and buffering device for a new energy construction machinery in this embodiment includes a chute 110 and a sliding rod 150. The chute 110 is provided with a hollow groove. The sliding rod 150 is arranged in the hollow groove of the chute 110 along the length direction of the chute 110. One end of the sliding rod 150 is fixedly connected to the chute 110. The length of the sliding rod 150 is greater than the length of the chute 110, so that the other end of the sliding rod 150 can be connected to a battery bracket 200 along the length direction of the chute 110, and the shock absorption and buffering device 100 is connected to the battery bracket 200.

[0030] A slider 120 and a shock absorption spring 140 are sleeved on the outer side of the axial direction of the sliding rod 150. The slider 120 can move freely along the length direction of the sliding rod 150. One end of the shock absorption spring 140 along the length direction is fixedly connected to the slider 120. When the slider 120 slides on the sliding rod 150, the shock absorption spring 140 is stretched or compressed, changing the deformation amount of the shock absorption spring 140, thereby offsetting the impact force received by the shock absorption and buffering device 100.

[0031] The slider 120 is connected to a connecting rod 130. One end of the connecting rod 130 is movably connected to the slider 120 along the length direction. The other end of the connecting rod 130 is connected to a battery pack 300 through an adhesive and a shock absorption and anti-slip pad. When the battery pack 300 is subjected to an impact force, the impact force received by the battery pack 300 is transmitted to the shock absorption and buffering device 100 through the connecting rod 130 for shock absorption.

[0032] A plurality of the shock absorption and buffering devices 100 are installed between the battery pack 300 and the battery bracket 200. When the new energy construction machinery vehicle brakes, starts, or is in a vibration condition, the impact force received by the battery pack 300 is transmitted to the connecting rod 130 of the shock absorption and buffering device 100. The connecting rod 130 drives the slider 120 to move along the sliding rod 150, so that the slider 120 compresses or stretches the shock absorption spring 140, changing the deformation amount of the shock absorption spring 140, and enabling the shock absorption and buffering device 100 to play a role in shock absorption and buffering for the battery pack 300.

[0033] The above embodiments only express a certain implementation manner of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention; therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
