Abstract
The utility model relates to a top rear cross beam weld assembly protective structure of mini car, which is composed of an inner plate of a top rear cross beam, an outer plate of the top rear cross beam, and a top cover, wherein the outer plate of the top rear cross beam, and the inner plate of the top rear cross beam are superposed and are fixedly welded on the edges to form a framework type top rear cross beam, so that the strength and the stiffness are increased. The top rear cross beam is welded on the lower part of the rear end of the top cover, and a plurality of weld expansion glue resisting ribs are added in the weld and combination position adjacent to the inner side of the top cover. Since expansion glue is coated in the inner sides of the resisting ribs, the rigid contact of the top rear cross beam and the top cover in the weld position is avoided. At the same time, the expansion glue is hardened after painted and treated at high temperature, and the expansion glue and the top cover are glued into integration. The utility model obtains the purpose of increasing the strength and the stiffness and reducing the vibration of the car body and the noise. The utility model does not increase the manufacturing cost of the components, and is suitable for various mini cars.
Description
Technical field
The utility model belongs to the auto body soldering part, is specifically related to the welded structure of a kind of baby car top after cross member.
Background technology
In order to guarantee that the baby car vehicle body has enough intensity, rigidity and in order to guarantee that body in white has enough welding precisions, top after cross member welding assembly had higher requirement.Because the top cover curved surface of most baby cars is all more smooth, and does not all have reinforced rib for car load is attractive in appearance on top cover, so automobile very easily vibrates in high-speed motion.Existing baby car is considered to such an extent that be not very comprehensive for the top cover vibration damping problem of automobile in motion process in the design of parts, occurs noise sometimes.
Summary of the invention
The purpose of this utility model is the problem at the prior art existence, after cross member welding assembly structure in a kind of baby car top is proposed, employing increases the way of welding expansion glue resistance muscle on the punching parts of top after cross member welding assembly, increase the contact surface of top after cross member welding assembly and top cover, increase buffer depth and solve this problem, also increased intensity, the rigidity of body in white simultaneously.
The technical solution of the utility model is as follows:
A kind of baby car top after cross member welding assembly structure, form by top after cross member inner panel, top after cross member outside plate and top cover, it is fixing that wherein top after cross member outside plate and top after cross member inner panel heavily are incorporated in edge's welding up and down, form the top after cross member of frame-type, intensity, rigidity are all relatively good like this, become to connect the main stressed member that a left side/right side weld all around connects the assembly rear portion.Above-mentioned top after cross member is welded on the bottom of top cover rear end again, and being in its solder bond by the top cover inboard increases many welding expansion glue resistance muscle, owing to scribble expansion glue in the resistance muscle, has avoided the top after cross member to contact with the rigidity of top cover at this place.The glue that expands simultaneously is through the after cure of application high-temperature treatment, and is bonding as a whole with top cover, reached promptly gain in strength, rigidity, reduced body vibrations again simultaneously and reduced the purpose of noise.
The advantage of present technique is:
The advantage of the utility model structure is: rational in infrastructure, and the purpose that reduces the top cover vibration be can reach, and intensity, the rigidity of vehicle body improved, do not increase the manufacturing cost of parts, be suitable for various baby cars.
Description of drawings
Fig. 1 is the structural representation of top after cross member part in the top after cross member welding assembly;
Fig. 2 is the sectional schematic diagram of top after cross member welding assembly structure.
The specific embodiment:
Referring to Fig. 1 and Fig. 2, baby car top after cross member welding assembly structure is by top after cross member inner panel 2, top after cross member outside plate 1 and top cover 3 are formed, at first top after cross member outside plate 1 and top after cross member inner panel 2 overlap the back up and down the fixing top after cross member (mainly seeing Fig. 1) that forms frame-type are welded in edge, again above-mentioned top after cross member is welded on the bottom of top cover 3 rear ends, lean on the solder bond of top cover inboard to be at the top after cross member and increase by three welding expansion glue resistance muscle 4, the expansion glue that is coated with in the resistance muscle is through the after cure of application high-temperature treatment, promptly with top cover bonding as a whole (mainly seeing Fig. 2), reached promptly and gained in strength, rigidity has reduced body vibrations again simultaneously and has reduced the purpose of noise.
Claims (1)
1, baby car top after cross member welding assembly structure, include top after cross member and top cover, it is characterized in that: the top after cross member is to be overlapped up and down by top after cross member outside plate (1) and top after cross member inner panel (2), and weld fixing and the formation tower structure to edge, the top after cross member is welded on the bottom of top cover (3) rear end, is provided with welding expansion glue resistance muscle (4) at the top after cross member by the inboard solder bond place of top cover (3).
