The technical scheme adopted for solving the technical problems is as follows:
The cold-rolled high-strength steel thin-wall pipe rear rib frame comprises a back plate and a pipe frame; the pipe frame is a frame structure formed by cold-rolled high-strength steel thin-wall pipe fittings and is fixedly connected with the backboard.
Further, the backplate bottom fixed is provided with pivot and pivot support, the pivot with the equal fixed connection of pivot support the pipe frame.
Further, a support frame in an H-shaped grid layout is fixedly arranged on the backboard.
Further, a round hole is formed in the backboard.
Further, the pipe frame is fixedly provided with an armrest support.
Further, a side wing supporting tube and a bent tube are fixedly arranged on the backboard.
The utility model has the beneficial effects that:
1. The utility model adopts the pipe frame formed by cold-rolled high-strength steel thin-wall pipe fittings, can reduce the framework weight of the rear seat of the electric automobile on the basis of meeting the strength of the framework of the rear seat of the electric automobile, and solves the problem that the framework weight of the rear seat of many electric automobiles is higher;
2. The support frame with the H-shaped grid layout can optimize the stress structure of the backboard, effectively reduce the collision risk from the rear of the vehicle, and eliminate abnormal sound under severe working conditions.
Drawings
FIG. 1 is a schematic diagram of a structure of a rear rib frame of a cold-rolled high-strength steel thin-wall pipe;
The device comprises a backrest lock 1, a lock bracket 2, a bracket 3-toptether, a side wing supporting pipe 4, a rotating shaft 5, a handrail bracket 6, a rotating shaft bracket 7, a pipe frame 8, a backboard 9, a headrest guide sleeve 10, a safety belt bracket outlet 11 and a bent pipe 12.
Detailed Description
The present utility model will be further described in detail with reference to the drawings and examples, which are only for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.
Examples:
the specific implementation process of the utility model comprises the following steps: the cold-rolled high-strength steel thin-wall pipe rear rib frame, as shown in figure 1, comprises a back plate 9 and a pipe frame 8; the pipe frame 8 is a frame structure formed by cold-rolled high-strength steel thin-wall pipe fittings and is fixedly connected with the backboard 9.
The welding surfaces of the cold-rolled high-strength steel thin-wall pipe fittings of the pipe frame 8 can be increased, the capacity of bearing various functional parts of the pipe frame 8 is enhanced, the flat pipe surface provides a plurality of positions for welding, various functional parts are convenient to install, and the pipe frame 8 can bear force and support the backboard 9.
As shown in fig. 1, the bottom end of the back plate 9 is fixedly provided with a rotating shaft 5 and a rotating shaft support 7, and the rotating shaft 5 and the rotating shaft support 7 are fixedly connected with the pipe frame 8.
The rotating shaft 5 and the rotating shaft bracket 7 can facilitate the back plate 9 and the pipe frame 8 to rotate together, the rotating shaft 5 and the rotating shaft bracket 7 adopt split layout, the rotating shaft 5 is close to the pipe frame 8, the total volume of the cold-rolled high-strength steel thin-wall pipe rear rib frame is reduced, and the stress condition of the cold-rolled high-strength steel thin-wall pipe rear rib frame is ensured.
As shown in fig. 1, the back plate 9 is fixedly provided with a support frame in an H-shaped grid layout.
The support frame in the H-shaped grid layout can carry out good stress support on the backboard 9, so that the stress intensity of the rib frame behind the cold-rolled high-strength steel thin-wall tube is improved.
As shown in fig. 1, the back plate 9 is provided with a circular hole.
The number of the round holes formed in the back plate 9 can be multiple, so that the weight of the back plate 9 is reduced.
As shown in fig. 1, the pipe frame 8 is fixedly provided with a handrail bracket 6.
The armrest support 6 may be of U-shaped design and cooperate with the tube frame 8 to provide a stable mounting location for the armrests of the rear seat.
As shown in fig. 1, the back plate 9 is fixedly provided with a side wing supporting tube 4 and a bent tube 12.
The bent pipe 12 is bent and expands outwards, the bent pipe 12 and the side wing supporting pipes 4 can provide shape support for the outer sleeve of the back row seat, and the back plate 9 can be fixedly provided with a back lock 1, a lock bracket 2 and a toptether bracket 3; the backrest lock 1 can be used for connecting the framework with the upper part of the vehicle body lock catch, and can be unlocked to enable the whole framework to fall down and further play a role in absorbing the impact force of the framework during collision; the lock bracket 2 can be used for bearing the backrest lock 1, adopts high-strength steel materials, is surrounded by an L shape, and strengthens the strength in a self-welding mode; toptether the bracket 3 is connected with the upper part of the hook of the child seat and is used for bearing the forward force of the child seat during impact; the top end of the pipe frame 8 can be further provided with a headrest guide sleeve 10 and a safety belt bracket outlet 11, the headrest guide sleeve 10 can be used for installing the headrest of the whole rear-row seat, two headrest guide sleeves are in a group, stable up-down tracks are provided for the movement of the headrest, and the structural design can be used for conveniently adjusting angles later, so that the requirements of different rear-row seats are met; the safety belt support outlet 11 is used for restraining a retraction outlet of a safety belt and strengthening weak parts of the framework; the headrest guide sleeve 10, the armrest support 6 and the backrest lock 1 can be in modularized design, so that the design multiplexing rate is improved, the subsequent back row seat assembly operation is efficient and convenient, the installation and maintenance of the back row seat are simpler, and the structure of the back row seat is more compact.
