The cross-section of backplate is the folded sheet form under the back door, including backplate body and setting under the backplate body turn-ups of limit towards the bending of back door panel beating below in order to shelter from the lower part of back door panel beating, for guaranteeing that the back door protects the whole outward appearance feel of board and with the cooperation clearance surface difference meet the requirements, needs reasonable design back door and protects board fastening structure. In the prior art, the design of the fixing point of the lower guard plate of the back door usually adopts the following two structures: 1. the fixing point is designed at the large surface of the lower guard plate body and fixedly connected with the metal plate, the flanging part has no fixing point and is in a free shape, the matching clearance between the flanging of the lower guard plate and the metal plate is not easy to control, and the guard plate is easy to be disengaged when the door is closed vigorously; 2. when the big face of backplate body designs the fixed point down, turn-ups design screw or snap fastener isotructure fasten, and turn-ups department can have screw (screw blanking cover) or snap fastener hourglass problem, and the outward appearance quality is relatively poor this moment.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a backplate mounting structure under car back door that fit clearance can be controlled and pleasing to the eye degree can be guaranteed again.
In order to realize the purpose, the utility model discloses a technical scheme be: the utility model provides a backplate mounting structure under car back door, is located vertical arrangement's lower backplate body including the face, the interior face that the backplate body closes on the panel beating down is protruding to be stretched and is provided with first buckle, and the first buckle is arranged in and is constituted the joint cooperation in the first calorie of seting up on the panel beating, and the lower curb of lower backplate body has the turn-ups towards panel beating direction buckle, and the turn-ups closes on protruding the stretching of interior face of panel beating and is provided with the second buckle, and the second buckle is arranged in and constitutes the joint cooperation in the second calorie of seting up on the panel beating, second buckle and turn-ups be contained angle formula and arrange and the contained angle alpha between the extension line of the protruding extension line of stretching the direction of second buckle and the extension line of the protruding orientation of first buckle is the acute angle.
In the above scheme, also set up the second buckle on the turn-ups, the buckle is through pushing up mechanism demolding to one side, and the buckle fastens the backplate on the panel beating, has certain angle with the protruding direction of stretching of second buckle and the main installation orientation of backplate body to realize the maneuverability of drawing of patterns.

Detailed Description
As shown in fig. 1 and fig. 2, a backplate mounting structure under car back door, including the face that is located vertical arrangement's lower backplate body 10, lower backplate body 10 closes on protruding the stretching of the interior face of panel beating 20 and is provided with first buckle 12, constitute the joint cooperation in the first card hole 21 of seting up on the panel beating 20 is arranged in to first buckle 12, the lower flange of lower backplate body 10 has turn-ups 11 towards panel beating 20 direction bending type, turn-ups 11 closes on protruding the stretching of the interior face of panel beating 20 and is provided with second buckle 13, second buckle 13 is arranged in the second card hole 22 of seting up on the panel beating 20 and constitutes the joint cooperation, second buckle 13 be the contained angle formula with turn-ups 11 and arrange and the contained angle alpha between the extended line of the protruding direction of second buckle 13 and the extended line of the protruding direction of first buckle 12 is the acute angle. The lower guard plate body 10 is fastened on the metal plate 20 through the first buckle 12, the second buckle 13 is arranged on the flanging 11 at the same time, the second buckle 13 is ejected out of the die through the inclined ejection mechanism, and a certain angle exists between the protruding direction of the second buckle 13 and the main installation direction of the lower guard plate body 10, so that the operability of die release is realized.
The metal plate 20 is provided with a guiding bevel edge 23 at a position corresponding to the second buckle 13, and features such as grooves and bosses are avoided, the slope of the guiding bevel edge 23 is larger than that of the flanging 11, so that the second buckle 13 is ensured to have enough space to move, the second clamping hole 22 is formed in the guiding bevel edge 23, and the second buckle 12 slides into the second clamping hole 22 along the guiding bevel edge 23.
Further, the second buckle 13 includes a second buckle seat 131 fixed on the inner surface of the flange 11, the second buckle seat 131 is obliquely and convexly arranged on the flange 11, and the second buckle head 132 is fixed on the end surface of the second buckle seat 131 and detachably connected with the second buckle seat. That is to say, during the molding, only the second buckle seat 131 and the turned-over edge 11 need to be integrally molded, and the second buckle head 132 with a proper size is selected to be installed on the second buckle seat 131 at the later stage, so that the structure of the mold is simplified, and the demolding of the lower protection plate is facilitated.
Similarly, the first buckle 12 includes a first buckle seat 121 fixed on the inner surface of the lower protection plate body 10, the first buckle seat 121 protrudes and extends in the horizontal direction on the lower protection plate body 10, the first buckle head 122 is fixed on the end surface of the first buckle seat 121, and the first buckle head and the first buckle seat constitute a detachable connection. That is to say, during the molding, only the first buckle seat 121 and the lower guard plate body 10 need to be integrally molded, and the first buckle head 122 with a proper size is selected to be installed on the first buckle seat 121 at the later stage, so as to simplify the structure of the mold and facilitate the demolding of the lower guard plate.
Further, the lower guard plate body 10 and the turned-over edge 11 are arranged at an obtuse angle and connected with the junction in a smooth transition mode. The wall thickness of the junction of the lower guard plate body 10 and the flanging 11 is smaller than that of the lower guard plate body 10 and the flanging 11, the wall thickness of the junction is thinned, a reinforcing rib structure cannot be designed in the region, the structural rigidity of the flanging is weakened, deformation of the flanging 11 is facilitated, and the assembling interference amount of the buckle of the flanging 11 is absorbed.
