A kind of rear seat of passenger car attachment point structure
Technical field
The invention belongs to auto body field, refer to a kind of structure of rear seat of passenger car attachment point especially.
Background technology
The back seat of current part manned vehicle can overturn forward, and volume for the luggage compartment obtains certain extension thus, can solve the placement demand of more article or overlength article.Turning seat general cost is higher, and the height being often configured in same money vehicle is joined on vehicle, and configures fixed seat in lower configuration.Because tip-up set is different from the installation positioning form of fixed seat, two kinds of different body platform assembly structures namely corresponding can be there are.If when body structure designs, just consider that the parts of these two kinds of mounting structures share, can greatly reduce time-to-market and cost.
Figure 1 shows that cushion frame schematic diagram, roll-over type seat can be divided into anterior attachment point 1, rear portion attachment point 2.Anterior attachment point 1 has Rotatable mechanism, is connected with body platform assembly by bolt; Rear portion attachment point 2, is linked by seat lock and vehicle body lock and connects.And fixed seat is because of structure without spin, therefore anterior attachment point 1, rear portion attachment point 2 are fixed support, are connected with body platform assembly by bolt.
Be illustrated in figure 2 the body mounts structure that tip-up set is corresponding, be divided into front mounting bracket assembly 3, rear mounting brackets assembly 4.The body mounts structure that fixed seat is corresponding as shown in Figure 3, is divided into front mounting bracket assembly 5, rear mounting brackets assembly 6.
Fig. 2 and Fig. 3 two kinds of body platform assemblies, front mounting bracket assembly 3 and front mounting bracket assembly 5 can be accomplished to share, and only this position of seat itself there are differences.And rear portion mounting bracket assembly 4, rear mounting brackets assembly 6 differ greatly, cause the body platform assembly structure that appearance two kinds is different, sheet metal component and welding jig need be developed respectively, cause and increase time-to-market and cost.Especially for volume production car, if the later stage increases certain seat configuration newly, except newly-increased mould, also need even again to develop the larger change of welding jig.If user in use wants to change seat configuration, also need manually to reprocess body platform assembly.
Summary of the invention
The object of the invention is the weak point for existing rear mounting brackets assembly, propose improvement opportunity scheme, different seat configuration in same vehicle can be realized by the technical program and use same body platform assembly.
The present invention is achieved by the following technical solutions:
A kind of rear seat of passenger car attachment point structure, includes rear mounting bracket assembly, snap close and rear mounting bracket; Described rear mounting bracket assembly is fixedly connected with certain angle with rear mounting bracket; Described rear mounting bracket assembly matches with relative body structure with the angle between rear mounting bracket;
Described rear mounting bracket assembly is provided with two fixed seat mounting holes; In the rear mounting bracket assembly is provided with two parallel snap close position-limited troughs; Snap close is fixedly installed in snap close position-limited trough.
Described snap close is linked together by connecting portion by the parallel double L-shaped one end wherein not in same plane; Described connecting portion is vertical with double L-shaped other one side.
Match with snap close position-limited trough in described double L-shaped one end be not connected with connecting portion.
Two fixed seat position of mounting hole on described rear mounting bracket assembly are provided with the projection contrary with snap close position-limited trough direction; The plane contrary with snap close is provided with project-welding nut.
Described mounting hole is arranged at the adjacent both sides of snap close position-limited trough.
The invention has the beneficial effects as follows:
1, solve the problem that different seat configuration causes occurring different body platform assemblies, realize the installation requirements simultaneously meeting different seat with same branch unit; 2, the parts realizing same vehicle share and maximize, and reduce exploitation, production, handling cost, shorten time-to-market.If 3, factory or user want to change the seat of different configuration, do not need amendment vehicle body sheet metal and changeable.

Detailed description of the invention
Describe technical scheme of the present invention in detail by the following examples, following embodiment is only exemplary, only can be used for explaining and technical scheme of the present invention being described, and can not be interpreted as being the restriction to technical solution of the present invention.
As shown in Figures 4 to 7, a kind of rear seat of passenger car attachment point structure, includes rear mounting bracket assembly 7, snap close 8 and rear mounting bracket 9; Described rear mounting bracket assembly 7 is fixedly connected with certain angle with rear mounting bracket 9; Described rear mounting bracket assembly matches with relative body structure with the angle between rear mounting bracket.
Snap close 8 becomes definite shape by round steel by mould bending, and described snap close is linked together by connecting portion by the parallel double L-shaped one end wherein not in same plane; Described connecting portion is vertical with double L-shaped other one side; Match with snap close position-limited trough in described double L-shaped one end be not connected with connecting portion.
After back seat, mounting bracket assembly 7 arranges snap close position-limited trough 10, mounting hole 11 at below welding projection welding nut.
Snap close 8 is placed on the snap close position-limited trough of mounting bracket assembly after back seat, uses CO2 gas shield arc welding to connect, mounting bracket assembly after composition back seat.
Roll-over type seat carries out clamping by the seat lock of seat self and snap close, can open when needing; Fixed seat carries out bolt by the support of seat self with mounting hole 11 and is connected.
Described rear mounting bracket assembly is provided with two fixed seat mounting holes; In the rear mounting bracket assembly is provided with two parallel snap close position-limited troughs; Snap close is fixedly installed in snap close position-limited trough.
After back seat, mounting bracket assembly is left and right symmetrical part, also can be used as left and right common elements, depending on rear floor assembly concrete structure; Shackle designs is common elements.Snap close is connected by CO2 gas shield arc welding with mounting bracket overlapping part after back seat, mounting bracket assembly after composition back seat.
Two fixed seat position of mounting hole on described rear mounting bracket assembly are provided with the projection contrary with snap close position-limited trough direction; The plane contrary with snap close is provided with project-welding nut.
Described mounting hole 11 is arranged at the adjacent both sides of snap close position-limited trough 10.
On assemble production line, according to configuration information, different seats is installed.Roll-over type seat is connected with snap close by seat lock, and fixed seat uses mounting hole 11 to carry out bolt connection.
Of the present invention being mainly needs the snap close used installing roll-over type seat and installs nut bore design that fixed seat needs to use on same branch unit, finally realizes same body platform assembly being installed arbitrarily difference and configures seat.
Although illustrate and describe embodiments of the invention, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments without departing from the principles and spirit of the present invention, scope of the present invention is by claims and equivalency thereof.
