Description

Installing support, door assembly and vehicle

Technical Field

The application relates to the technical field of vehicles, in particular to a mounting bracket, a vehicle door assembly with the mounting bracket and a vehicle.

Background

Four-door cars are typically equipped with revolving doors. Namely, one side of the vehicle door is hinged to a vehicle body metal plate; when the door is opened, one side of the door handle is installed and rotates around the hinged edge. When the swing type door is opened, a large lateral (i.e., vehicle body width direction) space is occupied. This causes at least the following two problems. Firstly, in narrow parking space, the door can not be opened completely, leads to the driver and the crew to get on or off the car difficulty. And secondly, pedestrians beside the vehicle may hit the suddenly opened vehicle door to cause the 'door opening killing' accident. Therefore, in the prior art, a swing-type vehicle door appears, which is connected to a vehicle body sheet metal through a connecting rod and can swing to the outside of the vehicle body by using the connecting rod to open the vehicle door. Its door opening effect is similar to that of a sliding door (i.e., a vehicle door slides in the front-rear direction of the vehicle), and does not occupy too much lateral space.

The swing type vehicle door can be connected with a vehicle body sheet metal through a main connecting rod and an auxiliary connecting rod. Wherein, the main connecting rod plays the important function of control door orbit, and how it is connected with door sheet metal is the problem that needs to solve urgently. When considering how to solve this problem, at least the following two aspects must be addressed. Firstly, how to ensure that the main connecting rod has enough connecting strength with the door sheet metal. And the connecting structure of the main connecting rod and the door sheet metal cannot excessively bulge (towards the inside of the vehicle along the thickness direction of the door) the door, otherwise, the connecting structure not only occupies the space in the vehicle, but also is exposed in the visual field of people in the vehicle, and the attractiveness of the interior trim of the vehicle is influenced. However, if the connecting structure of the main link and the door sheet metal is too far penetrated into the door (along the thickness direction of the door, toward the outside of the vehicle), on the one hand, the main link is very close to the door glass, and the safety gap between the main link and the door glass cannot be ensured; on the other hand, the master link may interfere with the door and crush, damaging the door trim. It can be seen that, in the connection structure of the main link and the door sheet metal, both protruding and intruding into the door can have adverse consequences. How to realize the connection of main link and door panel beating becomes a problem that is difficult to solve.

Advantageous effects

The application provides a installing support's beneficial effect as follows:

first, the mounting bracket has a rotating connecting portion and two fixed connecting portions (i.e., a first fixed connecting portion and a second fixed connecting portion). The rotation connecting part is rotatably connected with the end part of the connecting rod. The two fixed connecting parts are fixedly connected with the vehicle door metal plate. Therefore, the connecting rod and the door sheet metal can be stably and reliably connected through the mounting bracket, and the connecting rod and the door sheet metal have enough connecting strength.

Secondly, the rotation connecting part, the first extending part and the second extending part of the mounting bracket form an obtuse angle structure (also called as a left-hand structure). Based on this obtuse angle structure, inside the installing support both can invade the door to a certain extent, can protect the door again, ensures that the connecting rod is at the motion in-process, does not take place to interfere with the door. On the one hand, the rotation connecting portion of the mounting bracket intrudes into the door interior in the width direction of the vehicle; however, the two extending portions may extend toward the outside of the door, and their intrusion amount into the door is gradually reduced. On the other hand, the first extension portion can protect the door (generally, door trim) when the door is closed. That is, when the link reaches the limit position, if the movement is continued, the link may first hit the first extension portion, not the door sheet metal, thereby protecting the door. Likewise, the second extension can protect the door when the door is open.

Implementation mode one

As shown in fig. 1, in this embodiment, the mounting bracket includes a rotation coupling portion 100, a first extension portion 200, a second extension portion 300, a first fixing coupling portion 400, and a second fixing coupling portion 500. The rotation connection portion 100 connects ends of the link 600 as shown in fig. 2. The first extension portion 200 is fixedly connected to the rotation connection portion 100, and extends toward a first side of the rotation connection portion 100 to form a first extension end 210. The second extension part 300 is fixedly connected to the rotation connection part 100, and extends toward a second side of the rotation connection part 100 to form a second extension end 310. The first fixing connection portion 400 is fixedly connected to the first extension end 210 and fixedly connected to the door panel 700, as shown in fig. 3. The second fixing connection portion 500 is fixedly connected to the second extension end 310 and fixedly connected to the door panel 700, as shown in fig. 3. Wherein, the first extension portion 200, the second extension portion 300 and the rotation connection portion 100 form an obtuse angle structure; the rotation connecting portion 100 forms an apex 810 of the obtuse angle structure, the first extension portion 200 forms a first side 820 of the obtuse angle structure, and the second extension portion 300 forms a second side 830 of the obtuse angle structure.

Referring to fig. 2, the use of the mounting bracket provided in the present embodiment is described as follows:

in fig. 2, an arrow Z indicates the height direction of the vehicle; arrows Y1 and Y2 each indicate the width direction of the vehicle, Y1 being directed toward the inside of the vehicle, and Y2 being directed toward the outside of the vehicle. The mounting bracket is fixed to the door panel by two fixed connection portions (i.e., the first and second fixed connection portions 400 and 500), and is rotatably connected with the end of the link 600 by the rotating connection portion 100. During the closing process of the vehicle door, the connecting rod 600 rotates around the rotating connection portion 100 as a circle center, and gradually approaches the first extension portion 200 along the direction indicated by the arrow D1 until the state shown in fig. 3 is reached; during the opening of the door, the link 600 gradually approaches the second extension 300 in the direction of the arrow D2 until the state shown in fig. 4.

The beneficial effect of the installing support that this embodiment provided is as follows:

first, the mounting bracket has a rotation connecting portion 100 and two fixing connecting portions. The rotation connecting part 100 rotates the ends of the connecting rod 600 are connected. The two fixed connecting portions are fixedly connected with the vehicle door sheet metal 700. Therefore, the link 600 and the door panel 700 can be stably and reliably connected to each other with sufficient connection strength therebetween by the mounting bracket.

Next, the rotation connecting portion 100, the first extending portion 200 and the second extending portion 300 of the mounting bracket form an obtuse angle structure (may also be referred to as a back-off structure). Based on the obtuse angle structure, the mounting bracket can not only intrude into the vehicle door to a certain extent, but also protect the vehicle door, and ensure that the connecting rod 600 does not interfere with the vehicle door in the moving process, as shown in fig. 3 and 4. In fig. 3 and 4, Y1 and Y2 each indicate the width direction of the vehicle, Y1 being directed toward the inside of the vehicle, and Y2 being directed toward the outside of the vehicle. On the one hand, the rotation connecting portion 100 of the mounting bracket intrudes into the door interior in the width direction (Y2 direction) of the vehicle; however, the two extending portions (i.e., the first extending portion 200 and the second extending portion 300) extend toward the outside of the door (Y1 direction), and their intrusion amount into the door gradually decreases. On the other hand, when the door is closed, as shown in fig. 3, the first extension portion 200 can protect the door (generally, a door trim). When the link 600 reaches the position shown in fig. 3, if the movement is continued, the link 600 may first hit the first extension 200 instead of the door sheet metal 700, thereby protecting the door. Likewise, when the door is opened, as shown in fig. 4, the second extension 300 can protect the door.

By combining the two points, the mounting bracket provided by the embodiment has at least the following three functions, so that the technical problem of how to connect the main connecting rod with the vehicle door sheet metal in the swing type vehicle door is well solved. Firstly, the connecting rod 600 and the vehicle door sheet metal 700 can be provided with enough connecting strength; secondly, the glass door can be installed in the vehicle door with the minimum invasion, so that the beauty of the interior trim of the vehicle is ensured, the safety gap between the glass door and the vehicle door is ensured, and an installation space is reserved for accessories (such as a glass lifter) in the vehicle door to the maximum extent; thirdly, it can ensure that connecting rod 600 and door do not take place to interfere to the protection door is not extruded by connecting rod 600, avoids the door to be damaged.

It should be noted that in this embodiment, it is not limited which portion of the first extension portion 200 plays a role of protection. As shown in fig. 1, one end of the first extension portion 200 is fixedly connected to the rotation connection portion 100, and the other end extends to the outside of the rotation connection portion 100 along the first edge 820 and finally reaches the first extension end 210. The first extending end 210 may be used for protection, or a portion of the first extending portion 200 close to the rotation connection portion 100 may be used, or an intermediate portion of the first extending portion 200 between the first extending end 210 and the rotation connection portion 100. The skilled person can select which part of the first extension 200 is used to block the further movement of the link according to practical factors such as the door opening angle and the shape of the link, thereby preventing the link from impacting the vehicle door and protecting the vehicle door. Preferably, the protecting portion is the first extension end 210, or the middle portion. Similarly, the present embodiment does not limit which portion of the second extension 300 plays a role in protection; preferably, the second extension end 310 and the middle portion of the second extension 300.

As an example of the present embodiment, as shown in fig. 1, the first and second fixing-connecting parts 400 and 500 are each of a flat plate structure. The first fixed connection portion 400 is fixedly connected to the door sheet metal by two first bolts 410. The second connecting portion 500 connects the door sheet metal by two second bolts 510.

As an example of the present embodiment, as shown in fig. 1, a cylindrical hole is formed on the rotation connection portion 100; which can be rotatably connected to a cylindrical part (e.g., a pin) provided at the end of the connecting rod to effect rotational connection of the connecting rod to the mounting bracket. The arrangement positions of the cylindrical hole and the cylindrical part can be reversed; that is, a cylindrical member is provided at the rotation connecting portion 100, which rotatably connects cylindrical holes opened at the ends of the link.

Second embodiment

Based on the first embodiment, the first extension 200 is improved in the present embodiment. As shown in fig. 5, in the present embodiment, the first extending portion includes two parallel first extending rods 220. The first end of each first extension rod 220 is fixedly connected to the rotary connection part 100. The second ends of the two first extension rods 220 are connected into a whole through a first fixing connection part 400 and form the first extension end 210.

In the present embodiment, the first extension portion 200 is formed by only two first extension rods 220, which is beneficial to reduce the weight of the mounting bracket, and thus the weight of the door assembly and the vehicle. As shown in fig. 5, a hollow portion 230 is formed between the two first extension rods 220, and has a weight reduction effect. Since the hollowed-out portion 230 reduces the overall rigidity of the mounting bracket, the mounting bracket provided in the present embodiment is generally used when the vehicle door has a small weight.

Third embodiment

Based on the second embodiment, the present embodiment further improves the structure of the first extension portion 200. As shown in fig. 6, in the present embodiment, the first extension portion further includes at least one first reinforcing portion 240. The first reinforcing part 240 is fixedly connected between the two first extension rods 220.

Compared with the second embodiment, the first reinforcement part 240 proposed in this embodiment can reinforce the overall rigidity of the mounting bracket, thereby enabling the mounting bracket to provide greater attachment and support forces for the vehicle door. Particularly, when the vehicle door is in an open state, the vehicle door is suspended on the side of the vehicle, and the main connecting rod and the auxiliary connecting rod are required to provide enough connecting force and supporting force for the vehicle door.

The first reinforcement part 240 may be a plate-shaped structure as shown in fig. 6, in which case the number thereof is one. The first reinforcement 240 may also be a plurality of parallel reinforcement bars. One end of each reinforcing rod is fixedly connected with one first extension rod 220, and the other end of each reinforcing rod is fixedly connected with the other first extension rod 220.

Embodiment IV

Based on the first embodiment, the present embodiment improves the structure of the second extension 300. As shown in fig. 5, in the present embodiment, the second extending portion includes two parallel second extending rods 320. The first end of each second extension rod 320 is fixedly connected to the rotary connection part 100. The second ends of the two second extension rods 320 are connected into a whole through a second fixing connection part 500 and form the second extension end 310.

Similar to the second embodiment, the structure proposed in this embodiment is intended to reduce the weight of the mounting bracket. It should be noted that the second embodiment is independent from the present embodiment. In other words, when the mounting bracket adopts the structure of the second embodiment, it does not necessarily adopt the structure of the present embodiment; and vice versa. For example, the person skilled in the art may use the structure provided in the present embodiment for the second extension 300, but not the structure provided in the second embodiment for the first extension 200, according to the actual situation.

Fifth embodiment

Based on the fourth embodiment, the present embodiment further improves the structure of the second extension 300. As shown in fig. 6, the second extension further includes at least one second reinforcement 340. The second reinforcing part 340 is fixedly connected between the two second extension rods 320. Similar to the fourth embodiment, the present embodiment is intended to reinforce the overall strength of the mounting bracket; this embodiment is independent of the fourth embodiment.

The second reinforcement part 340 may be a plate-shaped structure as shown in fig. 6, in which case the number thereof is one. The second reinforcement 340 may also be a plurality of parallel reinforcement bars. One end of each reinforcing rod is fixedly connected with one second extending rod 320, and the other end of each reinforcing rod is fixedly connected with the other second extending rod 320.

Sixth embodiment

Based on the first embodiment, the present embodiment further improves the structure of the second extension 300. As shown in fig. 2 and 6, in the present embodiment, the second extension 300 is provided with one buffer portion 330. The buffer portion 330 is located on the moving path of the connecting rod 600, and as shown in fig. 2, a boss 610 used in cooperation with the buffer portion 330 is provided on the connecting rod 600.

In this embodiment, when the door is opened, the link 600 is turned toward the mounting bracket in the direction D2 shown in fig. 2; until the boss 610 contacts the bumper 330, the link 600 is stopped by the mounting bracket from further rotation, at which time the door reaches the maximum open position, as shown in fig. 4. That is, the buffer 330 provided in the present embodiment is actually a part of the stopper structure of the door opening limit. Through the limiting structure, the vehicle door can hover at a preset position when opened and cannot collide with a vehicle body; the connecting rod does not interfere with the vehicle door or the vehicle body due to overstroke.

Corresponding to the door opening limit is a door closing limit. The limit structure of the closing limit of the vehicle door is generally arranged on the vehicle body, and the mounting bracket does not participate in limit when the vehicle door is closed. When the door is closed in place, the mounting bracket and link are in the condition shown in fig. 3, and at this time, a gap is generally left between the link 600 and the first extension 200, and the link 600 does not collide with the mounting bracket.

Seventh embodiment

Based on the sixth embodiment, the present embodiment further improves the structure of the second extension 300. As shown in fig. 6, the second extension 300 includes a flat plate 350. The flat plate 350 is parallel to the rotation axis R of the rotation coupling 100. The buffer 330 is a flexible pad fixed on the surface of the flat plate.

In this embodiment, the flat plate 350 may also constitute the second reinforcement part 340. In this case, the flat plate 350 is not only a mounting seat for the flexible mat, but also can increase the overall rigidity of the mounting bracket, thereby achieving two purposes. The flexible mat material is not limited, for example, it may be made of an elastic material. The flexible pad may be secured to the surface of the plate 350 by bonding or the like.

Embodiment eight

Based on the first embodiment, in the present embodiment, the mounting bracket is an integrally formed structure. The integrally formed structure means that the blank of the mounting bracket can be integrally formed by casting or the like. In this case, the parts of the mounting bracket, for example, the rotation connecting part and the first extending part, are connected into a whole without providing a connecting structure, and are of an integral structure. When the integrally formed structure is adopted, the manufacturing process of the mounting bracket is simple, and the acquisition cost is favorably reduced. Meanwhile, the integrally formed structure omits a connecting structure among all parts of the mounting bracket, and the overall rigidity of the mounting bracket can be better ensured.

Ninth embodiment

The present embodiment provides a door assembly that uses the above-described mounting bracket. Therefore, the swing type automobile door can be used as a swing type automobile door, and the automobile body can be stably and reliably connected through the connecting rod. Meanwhile, a sufficient safety gap is formed between the window glass of the vehicle door assembly and the connecting rod, the interior of the vehicle door assembly is concise and attractive, and the vehicle door assembly cannot be damaged due to extrusion of the connecting rod.
