Specifically, the head collision is to use a round ball with the diameter of 165mm to impact the surface of the instrument panel at 24.1km/h, and the damage value of the head is judged according to the acceleration measured by a sensor in the round ball. The test requirements are as follows: in the test, the duration of the deceleration of the sphere exceeding 80g (g represents the acceleration of gravity) should not exceed 3ms, and no splashing of parts is allowed. In order to meet the performance, the auxiliary instrument panel handrail needs to be designed into a flexible body to absorb the excessive kinetic energy generated in the process of spherical collision, while the auxiliary instrument panel needs to meet the requirements of head collision energy absorption and simultaneously give consideration to the vibration resistance under the condition of whole vehicle vibration, so that the auxiliary instrument panel handrail needs to be designed into a rigid body to meet the modal requirement, which is contradictory to the requirements of head collision energy absorption, and the design difficulty is provided for people.
At present, in order to meet the requirements of head impact performance and modal performance, trial and error are often adopted when the auxiliary instrument panel armrest is designed, and the two performances can be met simultaneously until the middle point of the head impact performance and the modal performance is found, so that the difficulty is increased for the work of designing. The designed handrail has a complex structure, more fixed points, long improvement period, limited improvement mode, more increase of the manufacturing cost of the automobile due to unreasonable design improvement and influence on the market competitiveness of the automobile.

Disclosure of Invention
The technical problem to be solved by the invention is as follows: the buckle assembly has the advantages that the energy absorption effect is achieved, and meanwhile connection is firm.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the buckle assembly with the energy absorption structure comprises a buckle and a clamping card which are matched with each other, wherein the buckle is connected with the first component, and the clamping card is connected with the second component;
the buckle comprises a rabbit ear type buckle and two stand columns, and the rabbit ear type buckle is arranged between the two stand columns;
the joint card includes spacing muscle and two spacing muscle cards, and spacing muscle setting is between two spacing muscle cards, and spacing muscle is used for right two tops of rabbit ear formula buckle are spacing, and spacing muscle card is used for right spacing and joint in stand top rabbit ear formula buckle.
In the scheme, the root part of the rabbit ear type buckle is of a hollow structure.
In the scheme, the hollow structure at the root part of the rabbit ear type buckle is in a shape like a Chinese character 'kou'.
In the scheme, the cross section of the limiting rib is arched upwards, and the rabbit ear type buckle is located below the limiting rib.
The device of the invention has the beneficial effects that:
after the buckle assembly is clamped, the limiting rib clamp limits the top ends of the stand columns and clamps the rabbit ear type buckle, the limiting ribs limit the two top ends of the rabbit ear type buckle, the V-shaped structure of the rabbit ear type buckle is matched with the limiting ribs to form a ring energy absorption structure, and when collision occurs, the energy absorption structure forms an energy absorption ring to absorb energy generated by the collision.
The device of the invention has the following beneficial effects:
1. when collision happens, the V-shaped structures of the rabbit ear type buckles move towards two sides to absorb energy, and are clamped and connected with the limiting ribs on the two sides more firmly.
2. Rabbit ear formula buckle root is "mouth" font hollow out construction, and the energy input region's in the collision process of rabbit ear formula buckle root part partly, if this transmission energy is too big, crumple will take place in "mouth" font region, and then releases unnecessary energy and go out.
3. The cross section of the limiting rib is arched upwards, the rabbit ear type buckle is located below the limiting rib, and when the arch is pressed, the force can be transmitted to the adjacent part to abut against the arch foot to emit force, so that the rabbit ear type buckle can bear larger pressure.

Detailed Description
The invention is further described with reference to the following figures and examples:
as shown in fig. 1 and 3, an embodiment 1 of the present invention includes a buckle 1 and a snap-in card 2, which are matched with each other, the buckle 1 is connected with a first component 3, and the snap-in card 2 is connected with a second component 4.
The buckle 1 comprises a rabbit ear type buckle 11 and two upright posts 12, and the rabbit ear type buckle 11 is arranged between the two upright posts 12;
The rabbit-ear-type buckle 11 and the limiting rib 21 form a buckle ring structure.
As shown in fig. 1 and 2, the lower armrest cover structure for the vehicle interior according to embodiment 1 of the present invention includes a first member 3 which is a lower armrest cover, a second member 4 which is an upper armrest cover, and two side edges of the lower armrest cover of the console panel are provided with fasteners 1, and the upper armrest cover is also provided with 8 fastening clips 2 corresponding to the fasteners 1.
As shown in fig. 4, buckle 1 of lower cover and 2 phase-matchs of joint card of upper cover, buckle subassembly wholly divide into two parts from top to bottom, distribute between the upper and lower covers of handrail, and this buckle subassembly is not hard up for preventing that the upper and lower cover joint of handrail is not hard up and provides the protection, has promoted the joint fastness of upper and lower cover of handrail, compares in traditional joint structure, and this scheme is not firm with the joint and produces not hard up abnormal sound risk and fall to minimumly.
The upper part and the lower part of the whole buckle component form an energy-absorbing arch structure 5. During the head impact test process of the auxiliary instrument panel or when a passenger collides, the energy generated by the head of the passenger due to collision is absorbed by the arched structure, so that the safety of the passenger is ensured.
As shown in fig. 5, in embodiment 2 of the present invention, the root of the rabbit ear type buckle 11 is a hollow structure 6, and the hollow structure 6 at the root of the rabbit ear type buckle 11 is a square hollow structure.
In the energy input area in the collision process, after energy is input, more energy is absorbed into the ring structure 7 of the V-shaped area, interaction occurs in the area, and when the absorbed energy exceeds the bearable limit, energy transmission occurs, namely, the energy is transmitted to the hollow structure 6 area; if this transmission energy is too big, the regional ulcerate that will take place of "mouth" font contracts, and then releases unnecessary energy and go out, this buckle loop structure can play non-destructive energy-absorbing effect under the too big condition of collision energy, the problem of once less energy-absorbing just destruction has been avoided, have structural stability concurrently when having guaranteed the energy-absorbing effect, the effect of protection passenger head security has not only been played, the structure of buckle subassembly itself has stronger stability moreover.
The advantages of example 2 are: under the clamping and the state of the clamping buckle of the lower cover and the clamping and clamping buckle of the upper cover, the V-shaped structure of the clamping component can absorb energy generated by collision, and the mouth-shaped structure is used as an energy release groove. When the collision energy is smaller, the V-shaped structure absorbs the energy and plays a non-destructive energy absorption role; when the collision energy is larger, the V-shaped structure transmits the energy to the lower mouth-shaped structure, and the two structures absorb the collision energy at the same time, thereby playing a role in non-destructive energy absorption; when the energy is too large, the square-shaped area collapses to release the energy. The buckle assembly can play a non-destructive energy absorption role under the condition that the collision energy is not too large, the problem that the energy is damaged by small energy absorption once is avoided, and the energy absorption effect is ensured while the structural stability is achieved.
