Description

A kind of automobile connection structure of charcoal jar and mounting bracket

Technical field

The utility model relates to vehicular spare parts, is specifically related to the connection structure of a kind of automobile with charcoal jar and mounting bracket.

Background technology

Automobile, often is arranged on lower body crossbeam or the longeron according to installing and using requirement with the charcoal jar, because the charcoal tank mostly is a plastic parts, so its mounting means generally is to be fixed on the crossbeam of car body by final realization of mounting bracket.The charcoal tank bracket needs firm fixed plastics charcoal tank body, needs failure-free to be installed on the car body crossbeam again.At present, two kinds of structures of the mounting bracket of fixed carbon jar: the one, fix with two mounting brackets, the 2nd, fix with a mounting bracket.There is following some deficiency in the mounting bracket of above-mentioned two kinds of charcoal jars: though the first charcoal jar shape is comparatively simple, need two mounting brackets to link to each other with it by four bolts, cost is higher, and the Assembly ﹠Disassembly duration; The second charcoal jar can only be arranged vertically and vent uses up the time, can't satisfy the horizontal direction layout requirement, and in order to satisfy the dismounting requirement, the space that second charcoal jar top must be reserved is so that extract the second charcoal jar of clamping simultaneously.

Summary of the invention

The purpose of this utility model provides the connection structure of a kind of automobile with charcoal jar and mounting bracket, and it can be fixed on the car body by on even keel, can vertically be fixed on the car body again, and easy to assembly, accurate positioning connects reliably, can also reduce cost of product.

A kind of automobile described in the utility model connection structure of charcoal jar and mounting bracket, it is characterized in that: on the attachment face of charcoal tank shell, be provided with a pit and a guiding rib that links to each other with this pit, be respectively equipped with two symmetrical catch in the both sides of pit; Four catch raise up and to two lateral bucklings, form four grooves between the attachment face of the following and charcoal jar of four bendings; On each catch, be provided with two reinforced ribs, to guarantee the strength and stiffness of catch; Described pit, guiding rib, catch and reinforced rib and charcoal jar single injection-molded;

Be provided with a flange on corresponding of mounting bracket and charcoal jar attachment face, be provided with boss on this flange, the pit on the shape of boss and position and the charcoal jar is suitable; On mounting bracket, be provided with projection everywhere, everywhere four groove corresponding matching on projection and the charcoal jar; Also be provided with a reinforced rib, a flange reinforced hole and three support mounting holes on mounting bracket, mounting bracket is one time punching molded structure.

Described a kind of automobile connection structure of charcoal jar and mounting bracket, its described pit is rectangle, and a guiding rib that links to each other with this pit is wedge shape.Guiding rib is injection-moulded on the surface of shell of charcoal jar, and it is concordant with the pit upper surface that the lower end originates in surface of shell, the upper end of charcoal jar, is convenient to that the boss on the mounting bracket slides in the pit smoothly along guiding rib in the fitting process.

Described a kind of automobile is rectangle or is oval with the connection structure of charcoal jar and mounting bracket, its described catch.

The utility model is the clamping that the groove corresponding matching of injection mo(u)lding on projection on the charcoal jar mounting bracket and the charcoal jar is realized the charcoal jar; After clamping put in place, the boss on the mounting bracket entered into the pit on the charcoal jar, had both played spacing effect and had realized the firm of clamping simultaneously, made the charcoal jar be difficult for deviating from; After charcoal jar and bracket clamp were received the position, assembly was realized layout and the installation of charcoal jar assembly on vehicle body by three bolt are installed on car body crossbeam or longeron.

The utility model is compared with prior art and had the following advantages: it can be fixed on the car body by on even keel, can vertically be fixed on the car body again, and clamping firmly is difficult for deviating from, and easy to assembly, and accurate positioning can also reduce cost of product.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Use the connection structure of charcoal jar and mounting bracket referring to Fig. 2, Fig. 3, Fig. 4, Fig. 5 and a kind of automobile shown in Figure 6, on the attachment face of charcoal jar 31 housings, be provided with a pit 33 and a guiding rib 34 that links to each other with this pit, be respectively equipped with two symmetrical catch 36 in the both sides of pit 33; Four catch raise up and to two lateral bucklings, form four grooves 32 between the attachment face of the following and charcoal jar of four bendings; On each catch, be provided with two reinforced ribs 35; Described pit, guiding rib, catch and reinforced rib and charcoal jar single injection-molded;

Be provided with a flange 42 on corresponding of mounting bracket 41 and charcoal jar 31 attachment faces, be provided with boss 47 on this flange, the pit 33 on the shape of boss and position and the charcoal jar 31 is suitable; Be provided with projection 43 everywhere on mounting bracket, the degree of depth of the groove 32 on the thickness of projection and width and the charcoal jar and width shape coincide everywhere, everywhere four groove 32 corresponding matching on projection and the charcoal jar 31; Also be provided with a reinforced rib 46, flange reinforced hole 45 and three support mounting holes 44 on mounting bracket, mounting bracket is one time punching molded structure.

Described pit 33 is rectangle, and a guiding rib 34 that links to each other with this pit is wedge shape.Guiding rib is injection-moulded on the surface of shell of charcoal jar, and it is concordant with the pit upper surface that the lower end originates in surface of shell, the upper end of charcoal jar, is convenient to that the boss on the mounting bracket slides in the pit smoothly along guiding rib in the fitting process.

Described catch 36 is rectangle, and another embodiment is oval.

Punching press simultaneously has an oblong flange 42 on mounting bracket 41, is suppressed with boss 47 on the flange, and the front end of boss 47 is the rounding off cambered surface, does not damage guiding rib when realizing in the fitting process slide relative with charcoal jar guiding rib 34, and is easy to slide; The rear end is a vertical plane surface, is embedded into after being seated in the charcoal jar upper groove 33, is difficult for deviating from after making charcoal jar and support clamping, realizes spacing and latch functions.

Fitting process of the present utility model: after the groove alignment of the projection of mounting bracket and charcoal jar with the parallel charcoal jar that pushes of support, simultaneously, boss on the mounting bracket flange upwards slides along the wedge shape guiding rib, the mounting bracket flange produces elastic deformation, when the projection of mounting bracket entered in the charcoal jar groove fully, the boss of mounting bracket was positioned at the top of the pit that sticks into the charcoal jar, and the elastic deformation of mounting bracket flange recovers, boss falls into pit, and the charcoal jar is installed and reached spacing and locking.Mounting bracket has limited moving of charcoal jar all directions, charcoal jar belt supporting frame is fixed on the car body with three bolts by the bolt hole again, can realize being arranged vertically or being arranged in parallel on car load of charcoal jar.

The structure that mounting bracket of existing usefulness shown in Figure 1 is fixing is welded on mounting bracket 21 on the car body earlier, cooperates with the flange 24 of mounting bracket by the groove 23 on the second charcoal jar 22 the charcoal jar is snapped fit onto on the mounting bracket again.
