Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

A vehicle tailgate lock reinforcement plate 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 4.

According to the utility model discloses vehicle back lock reinforcing plate 100 can include: a reinforcing plate body 1 and a plurality of reinforcing grooves.

As shown in fig. 1 and 2, both ends of the reinforcing plate body 1 are formed as fixing ends adapted to be connected with the back door inner panel 200 and the back door outer panel 300, respectively. That is, the reinforcing plate body 1 is disposed in a cavity formed between the back door inner and outer plates and connected between the back door inner plate 200 and the back door outer plate 300 to play an effective reinforcing role, so as to improve the overall strength and impact resistance of the vehicle back door.

In order to further improve the strength of the vehicle back door lock reinforcing plate 100 itself, so as to improve the reinforcing effect on the vehicle back door, the embodiment of the present invention makes a plurality of reinforcing grooves respectively formed on the reinforcing plate body 1 and located between the fixed ends at both ends, and makes the opening direction of one part of the reinforcing grooves opposite to the opening direction of the other part of the reinforcing grooves.

That is to say, the utility model discloses the different enhancement recesses that two-way opening set up have been adopted on vehicle back lock reinforcing plate 100 to effectual vehicle back lock reinforcing plate 100 self intensity that has promoted, and then the effectual enhancement effect to the vehicle back door that has improved, so that the intensity and the anti striking performance of vehicle back door are better, and the fatigue durable promotion effect of solder joint between rigidity and stiff end and back door inner panel 200 and back door outer panel 300 to the rigidity of two stiff ends is showing.

According to the utility model discloses vehicle back lock reinforcing plate 100, this vehicle back lock reinforcing plate 100 adopt the enhancement recess of opening opposite direction to promote self rigidity and intensity, and then the effectual enhancement effect to the vehicle back door that has improved to rigidity and stiff end and the solder joint fatigue endurance's between stiff end and back door inner panel 200 and the back door outer panel 300 promotion effect to two stiff ends is showing.

Referring to fig. 1 to 4, the openings of adjacent two reinforcing grooves are opposite in direction. Therefore, the overall structure of the vehicle back door lock reinforcing plate 100 can be made to have larger fluctuation, the strength of the vehicle back door lock reinforcing plate 100 can be further improved, and the reinforcing effect on the vehicle back door can be effectively improved.

As shown in fig. 1 to 4, the reinforcing grooves are two, and the two reinforcing grooves include: a first recess 2 and a second recess 3, wherein the opening of the first recess 2 is upward in the height direction of the vehicle, and the opening of the second recess 3 is downward in the height direction of the vehicle. That is, the back door lock reinforcement plate 100 of the vehicle is designed to have a double "U" shape structure, which is a combination of a positive U shape and a negative U shape. Therefore, the strength and rigidity of the vehicle back door lock reinforcing plate 100 can be increased, and the reinforcing effect on the vehicle back door can be further effectively improved.

Further, the first groove 2 and the second groove 3 are continuously formed on the reinforcing plate body 1. Thus, the overall structure of the vehicle back door lock reinforcing plate 100 can be made more compact, so that the strength and rigidity of the vehicle back door lock reinforcing plate 100 are made greater.

Still further, the outer side wall of the first groove 2 is configured as the inner side wall of the second groove 3. Two strengthen a lateral wall of recess sharing promptly, and then can more save space, form more and strengthen the recess promptly in the narrower space on reinforcing plate body 1, and then can make vehicle back lock reinforcing plate 100's overall structure compacter, intensity is bigger.

In conjunction with the embodiment shown in fig. 1 to 4, the inner sidewall of the first groove 2 is configured as a first fixing end 11 of the fixing ends, the first fixing end 11 being connected with the back door inner panel 200, and the outer sidewall of the second groove 3 is configured as a second fixing end 12 of the fixing ends, the second fixing end 12 being connected with the back door outer panel 300. In other words, since the sidewalls of the two reinforcing grooves are configured as the two fixing ends of the back door lock reinforcing plate 100 for the vehicle, the rigidity of the fixing points and the fatigue durability of the welding points between the fixing points and the back door inner plate 200 and the back door outer plate 300 are effectively improved.

Wherein, because the second stiff end 12 of being connected fixedly with back door planking 300 is the lateral wall of second recess 3, consequently, second stiff end 12 and back door planking 300's hookup location compare in the stiff end of the vehicle back door lock reinforcing plate of traditional "Z" style of calligraphy and the hookup location of back door planking will lean on more, consequently, can effectively promote the enhancement support effect to back door planking 300, and then the effectual anti-sinking performance who promotes back door planking 300.

Referring to fig. 1 to 4, the bottom wall of the first recess 2 is configured as a back door lock mounting part 21, and a vehicle back door lock 400 is adapted to be fixed to the back door inner panel 200 through the back door lock mounting part 21. Specifically, the back door lock mounting portion 21 has a first fixing hole adapted to face a second fixing hole of the back door inner panel 200, and the vehicle back door lock 400 is installed to pass through the first fixing hole and the second fixing hole to fix the vehicle back door lock 400 to the back door lock mounting portion 21 and the back door inner panel 200.

From this, can effectively increase the installation intensity of vehicle back door lock 400 to improve vehicle back door lock 400's the stability of setting.

According to some embodiments of the present invention, the highest point of the top wall of the second groove 3 is not higher than the first fixed end 11. Therefore, a welding gun operation space is reserved for welding and fixing between the first fixed end 11 and the back door inner plate 200, so that local avoidance of welding spot positions is realized, operation is facilitated, and assembly is more convenient.

As shown in fig. 1 and 3, reinforcing flanges 13 are formed on both sides of the reinforcing plate body 1, and both ends of the reinforcing flanges 13 extend to fixed ends of both ends, respectively. Thus, the reinforcing flange 13 is connected to the fixed end as a reinforcing unit, so that the overall strength of the back door lock reinforcing plate 100 can be further improved.

The vehicle back door lock reinforcing plate 100 can be integrally formed by adopting a stamping process, and the reinforcing flange 13 can be formed on the reinforcing plate body 1 by adopting the stamping process so as to ensure the stability and the integral strength of the vehicle back door lock reinforcing plate 100.

A vehicle according to another aspect of the present invention includes the vehicle back door lock reinforcement plate 100 described in the above embodiments. Other configurations of the vehicle, such as transmissions, braking systems, steering systems, etc., are known in the art and well known to those skilled in the art, and therefore will not be described in detail herein.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
