A kind of novel storage battery pressure plate structure
The utility model relates to a kind of connection structure, refers more particularly to a kind of novel storage battery pressure plate structure that improves battery cradle support strength
When automobile engine nacelle layout design, because needs reserve engine air inlet tube, coolant inlet pipe, change speed gear box, the arrangement space of some parts of head light etc., thereby storage battery often can not directly be arranged on longitudinal beams of engine cabin and make longeron directly carry battery weight, but by cantilevered bracket, storage battery is suspended in to longeron outside, this cantilever design, cantilever is longer, the stress that storage battery produces bracket is larger, battery cradle just more easily occurs that fatigue cracking even occurs in distortion, in order to prevent the generation of problems, orthodox method is the way that directly increases the material thickness of battery cradle or adopt more high-intensity steel plate, but easily make cost and complete vehicle weight increase, also can increase material cost.
And improve support strength by improving supporting construction, if China Patent No. is 201120292776.7, name is called the utility model patent of front supporting frame of storage battery bracket, a kind of front supporting frame of storage battery bracket is disclosed, comprise a symmetrically arranged left side, right side board, this left side, the upper end of right side board is connected by horizontal plate, the rear end of described horizontal plate is by being bent to form vertical flange, although the support intensity after improving increases, but do not change yet two point-supported Design Modes, bearing stress still concentrates on longeron, thereby the cantilever of bracket cannot be extended to the storage battery of breaking away from machinery space and arrange limitation.
Utility model content
The utility model mainly solves traditional storage battery bracket undercapacity easily distortion or fatigue cracking, and increase material thickness or intensity improve the technical matters of weight or cost; A kind of novel storage battery pressure plate structure that can improve battery cradle support strength is provided.
In order to solve the technical matters of above-mentioned existence, the utility model is mainly to adopt following technical proposals:
A kind of novel storage battery pressure plate structure of the present utility model, compression for automotive battery is spacing, storage battery fixer comprises bracket and pressing plate, described bracket comprises mounting plate and the bottom plate of three-legged structure, bottom and the longitudinal beams of engine cabin of described mounting plate are affixed, the top plane of mounting plate forms storage battery carrying surface, described bottom plate bottom and longitudinal beams of engine cabin are affixed, bottom plate top and mounting plate top are affixed and support mounting plate, described pressing plate comprises some positioning plates, connection the fixedly connecting panel of positioning plate, between the carrying surface on pressing plate and mounting plate top, be provided with pull bar, described pull bar one end and pressing plate are affixed, the other end and mounting plate are affixed, it is affixed that one end of described connecting panel and machinery space head light are installed crossbeam, on the battery cradle basis of three-legged structure, original only two-point pressing plate spacing for storage battery clamping and that do not carry the weight of storage battery own is improved to bikini structure, can with driving engine head light, being fixedly connected with of crossbeam be installed by bikini pressing plate, the weight transmitting of a part of storage battery to head light is installed on crossbeam, reduced the stressing conditions of battery cradle, prevent that battery cradle from occurring being out of shape even fatigue cracking because of suffered compared with large stress.
As preferably, described connecting panel is trench structure, one end of connecting panel is provided with tie rod hole, described pull bar is threaded with connecting panel through tie rod hole, the other end of connecting panel is provided with connecting bore, and connecting panel is installed transom bolt by connecting bore and described head light and is connected, and connecting panel adopts trench structure, can improve the structural strength of connecting panel itself, bear better a part of weight of tractive storage battery itself.
As preferably, described positioning plate is two, positioning plate is bending structure, the vertical plane of two positioning plates is the corresponding two sides that fit in storage battery respectively, the horizontal surface of positioning plate fits in the end face of storage battery, weld with the horizontal surface of two positioning plates respectively the bottom surface of described connecting panel, the positioning plate that crossbeam is installed near head light is provided with tie rod hole, described pull bar is threaded with positioning plate through described tie rod hole, two positioning plates touch storage battery and compress storage battery by pull bar, connecting panel is connected firmly two positioning plates and forms whole storage battery pressure plate structure, and connecting panel is installed crossbeam with driving engine head light and is connected, born the weight of a part of storage battery, reduced the stressed of battery cradle, therefore, under equal conditions, what can make that the cantilever of battery cradle can design is longer, break away from the design arrangement limitation of storage battery, for the layout of other auto parts and components remains out arrangement space more fully.
The beneficial effects of the utility model are: on the battery cradle basis of three-legged structure, original only two-point pressing plate spacing for storage battery clamping and that do not carry the weight of storage battery own is improved to bikini structure, by the connecting panel of bikini pressure plate structure, with driving engine head light, crossbeam being installed is fixedly connected with, and in conjunction with pull bar, a part for the battery weight that former cause bracket is carried completely is passed to head light and installs on crossbeam, shared a part of bracket stress, the corresponding stressing conditions that reduces bracket, can prevent that bracket from occurring because bear occurs being out of shape the even situation of fatigue cracking compared with large stress, safety is higher, simultaneously, in the situation that bracket is stressed on an equal basis, also can make the longer of bracket cantilever design, break away from the layout limitation of battery, for the layout of other auto parts and components remains out arrangement space more fully.
