Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings, but the present invention is not limited thereto.

[0031] The up, down, left and right mentioned in this manual refer to image 3 up, down, left, and right directions.

[0032] figure 1 It shows a knee energy-absorbing protection device provided by the present invention, which includes a main beam 1 , two energy-absorbing brackets 2 and a knee guard 3 . Wherein, the two ends of the energy-absorbing bracket 2 are respectively connected to the main pipe beam 1 and the knee shield 3, the main pipe beam 1 is fixed on the vehicle body, and the knee shield 3 faces the knees of the occupants in the vehicle, thus forming the entire Knee energy-absorbing protectors. Such as figure 2 As shown, preferably, the knee guard 3 is generally rectangular, and first and second cross ribs ( 4 , 5 ) are arranged on it to strengthen the rigidity of the knee guard 3 . Since the magnes...

Abstract

The invention relates to a knee energy-absorbing protecting device and an energy-absorbing support and aims at improving the problem that existing protecting devices are low in energy-absorbing efficiency. The protecting device comprises a manifold beam, a knee protecting plate and the energy-absorbing supports connecting the manifold beam with the knee protecting plate, each energy-absorbing support is formed by an outer frame and an inner supporting member supporting the outer frame, each outer frame comprises an upper frame, a lower frame, a left frame and a right frame, the upper frames and the lower frames are opposite in position, the left frames and the right frames are positioned at two ends of the upper frames and the lower frames, each inner supporting member comprises a first supporting member connecting the upper frame and the corresponding lower frame respectively, a second supporting member and a third supporting member, and the second supporting member and the third supporting member are positioned on the left side and the right side of the corresponding first supporting member. The upper frames and the lower frames are waved and are provided with multiple thinning portions and adjusting holes, so that after a collision occurs, collision energy can be effectively absorbed through deformation at the adjusting holes and the thinning portions.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to a knee energy-absorbing protection device and an energy-absorbing bracket used inside a cockpit assembly. Background technique [0002] There are many kinds of knee protection technologies used in automobiles, including setting airbag devices on the knees, sheet metal energy-absorbing brackets, foam energy-absorbing blocks, etc. The knee airbag device uses the airbag to cushion the energy of the collision, so as to protect the knee from injury. Generally speaking, the cost of knee airbags is relatively high, so they are mostly equipped in mid-to-high-end cars. In addition, the knee airbag modules are also relatively large in size and heavy in weight, making it difficult to arrange them in compact cars. The sheet metal energy-absorbing bracket cushions the collision of the knee through the deformation of the bracket to reduce the damage to the knee. However, sheet metal energy-a...
