Detailed Description

In the following description, the front-rear direction refers to the vehicle length direction, and the direction in which the vehicle advances is referred to as the front, and the direction in which the vehicle retreats is referred to as the rear. The left-right direction is a vehicle width direction, and left and right directions when the driver faces forward are referred to as left and right directions, respectively. The vertical direction is a vehicle height direction, and the direction on the ground side is set to be downward and the direction on the opposite side is set to be upward with respect to the vehicle. This is merely for convenience in describing the invention and to simplify the description, and is not intended to indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and is therefore not to be considered limiting of the invention.

The present invention will be described in detail with reference to the following embodiments, and fig. 2 shows a schematic structural diagram of a roof assembly of an automobile of the present invention, which is composed of a roof support member 1, a roof glass 2, a reinforcing beam 3, and the like, wherein the roof support member 1 is a frame structure, and a glue containing groove is formed at the periphery thereof for fixing and bonding the roof glass 2. The reinforcing beam 3 is provided near the middle of the roof support 1.

Fig. 3 and fig. 4 respectively show the schematic structural diagram and the partial enlarged view of I of the roof support member in the automobile roof assembly of the present invention. It can clearly be seen that the supporting cross-members 11, which increase their own bending strength, are arranged in the front-rear direction of the roof support 1. The reinforcement beam 3 is detachably fixed to a position directly above the support cross member 11. The specific embodiments are made with reference to the following: the left and right ends of the reinforcing beam 3 are both formed into flat openings 31 (as shown in fig. 5), and correspondingly, the front left and right side walls of the roof support 1 are provided with slots 12 adapted to the shapes of the flat openings 31. The car roof assembly further includes a locking bolt (not shown), and correspondingly, an inner thread adapted to the locking bolt is formed on the upper side wall of the slot 12. When the reinforcing beam 3 is placed in place relative to the slot 12, it is fixed by the locking bolt in time, so that the reinforcing beam 2 and the roof support 1 form a stressed whole. Thus, on the premise of ensuring the lightweight design of the automobile top leaning assembly, the top cover supporting piece 1 can have high structural strength and bending resistance by adopting the technical scheme for arrangement. In addition, the stiffening beam 3 is fixed on the top cover supporting piece 1 in an inserting mode, on one hand, the forming difficulty of the top cover supporting piece 1 is reduced, and the forming cost is reduced; on the other hand, the reinforcing beam 3 with different strengths can be conveniently adapted and installed according to the specific requirements of different vehicle types.

It should be noted that a boss 13 may be further disposed on the upper sidewall of the slot 12, and an internal thread for adapting the locking bolt is opened therein. Through adopting above-mentioned technical scheme to set up, can improve the fixed reliability of stiffening beam 3 greatly, prevent to take place the phenomenon of ftractureing at the bolt joint in the in-service use. Furthermore, a strip-shaped reinforcing protrusion 14 may be further disposed on the periphery of the boss 13. The method specifically comprises the following steps: in the present embodiment, each end of the reinforcing beam 3 is provided with two bosses 13, which are connected together by the strip-shaped reinforcing protrusion 14, so as to bear the force as a whole.

In order to further improve the bending strength of the roof support 1 in the front-rear direction, as a further optimization of the above-described roof assembly, a series of reinforcing plates 4 may be additionally provided right above the supporting cross member 11 and in the left-right direction. In addition, the reinforcing plate 4 may also serve as a stopper for the reinforcing beam 3, that is, a socket 41 (shown in fig. 6) is formed on the reinforcing plate to match the outer shape of the reinforcing beam 3.

Furthermore, as a further optimization of the structure of the roof support 1, the reinforcing beam 3 and the reinforcing plate 4 are hidden in the supporting beam 11, which can be done as follows: the support beam 11 is provided with a sinking groove 111 for sinking the reinforcing beam 3 and the reinforcing plate 4.

In the actual installation process, the reinforcing plate 4 is firstly sleeved on the reinforcing beam 3 and then inserted into the slot 12 as a whole, then the locking bolts are used for fixing the two end parts of the reinforcing beam 3, and finally, the bonding agent is smeared at the joint of the reinforcing plate 4 and the supporting beam 11. As a further optimization, the insertion opening 41 formed on the reinforcing plate 4 should be slightly larger than the cross-sectional dimension of the supporting beam 11, and the unilateral clearance is preferably controlled to be 0.2-0.5 mm.

Furthermore, considering the bending strength and the structural design of the roof support 1, the arrangement and density of the reinforcing plates 4 can be controlled, and the reinforcing plates 4 run along the front-back direction of the roof support 1, and the spacing is generally controlled to be 50-100 mm.

Finally, the roof support 1 is preferably an integrally molded plastic part, in view of overall structural strength, weight reduction, and ease of construction. The reinforcing beam 3 is preferably an aluminum alloy piece. The reinforcing plate 4 is preferably a plastic part.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
