Description

Mounting rack and vehicle Technical Field

The present disclosure relates to the technical field related to vehicles, and in particular to a mounting bracket and a vehicle.

Background technique

The door is connected to the vehicle body mainly through a hinge containing an axle pin. The hinge of a conventional vehicle includes a male hinge fixed to the vehicle body and a female hinge fixed to the door. A revolving door usually only includes two hinge systems on the same axis, and the hinge is installed in only one direction, at the vehicle body end and the door end. Therefore, the force direction of the conventional door hinge is single and the structure is relatively simple.

However, for buses, coaches and small vehicles with swing doors, the hinge bracket at the end of the body is subjected to a large torque and changes continuously as the door opens. For this reason, the hinge bracket at the end of the body must have high structural strength, good stability, high installation accuracy, and must consider characteristics such as simple production process and lightweight. Through design iterations, conventional vehicle stamping steel plate hinges, multi-layer sheet metal welding combination hinges, steel processing hinges and extruded aluminum hinges were excluded. The reasons are: the stamping process cannot meet the multi-layer reinforcement structure perpendicular to the installation surface; the multi-layer steel plate welding combination process is complex and the accuracy is difficult to guarantee; the material utilization rate of the steel processing hinge is low and the processing cost is high; the extruded aluminum hinge can only generate reinforcement ribs in the extrusion direction and cannot meet the reinforcement structure perpendicular to the installation surface.

As shown in FIG1 , a mounting frame 1 is applied to a vehicle. The vehicle includes a vehicle body and a vehicle door. The mounting frame 1 includes a bottom plate 10, a first mounting plate 12, a second mounting plate 13, a third mounting plate 21, a plurality of first mounting holes 11 and at least two second mounting holes 14. The first direction is the A direction in FIG1 , and the second direction is the B direction in FIG1 Generally speaking, when the mounting bracket 1 is fixedly mounted on the vehicle body, the first direction A is a horizontal lateral direction, and the second direction B is a vertical longitudinal direction. Of course, the present disclosure does not limit the first direction A and the second direction B.

The bottom plate 10 is a main structure for fixed connection with the vehicle body, and therefore, the bottom plate 10 is thicker than the first mounting plate 12, the second mounting plate 13, and the third mounting plate 21. The bottom plate 10 in the present disclosure includes a surface 100. The surface 100 includes a first mounting surface 101 and a second mounting surface 102, so that the mounting area of the mounting frame 1 is dispersed, thereby improving the stability of the mounting frame 1.

The plurality of first mounting holes 11 are used to connect with the vehicle body. The plurality of first mounting holes 11 are distributed on the bottom plate 10 and the third mounting plate 21 to increase the fixing points and fixing areas between the mounting frame 1 and the vehicle body. The first mounting holes 11 extend along the first direction A. In this way, the first mounting holes 11 used to connect with the vehicle body are unified to extend along the first direction A, which reduces the complexity of the structure of the mounting frame 1, so that the mounting frame 1 can be integrally cast.

The first mounting plate 12 is arranged on the surface 100, and its thickness direction is perpendicular to the first direction. The first mounting surface 101 and the second mounting surface 102 are respectively located on both sides of the first mounting plate 12. The second mounting plate 13 is arranged on the second mounting surface 102, and its thickness direction is perpendicular to the first direction. The material of the mounting frame 1 in the present disclosure includes aluminum alloy or other lightweight materials, and the density is reduced by two-thirds compared with the original steel material, that is, the weight of the mounting frame 1 is reduced, and the lightweight effect of the mounting frame 1 is good. However, the rigidity of the same aluminum alloy material is poor, and the door opening method in the present disclosure will cause the first mounting plate 12 to bear a large torque and change continuously with the door opening process. At this time, if the first mounting plate 12 is arranged on the upper edge of the bottom plate in a traditional manner, then, considering that the installation space between the first mounting plate 12 and the second mounting plate 13 is also used for the installation of the rotating shaft 3, the rotation and avoidance of the connecting member 4, and the installation of the drive motor, it is impossible to set a sufficient reinforcement structure between the first mounting plate 12 and the second mounting plate 13 to ensure the structural strength of the first mounting plate 12 and the second mounting plate 13. Therefore, the present invention disposes the first mounting plate 12 in the middle area of the base plate 10 and divides the surface of the base plate 10 into a first mounting surface 101 and a second mounting surface 102, so that during the casting process of the mounting frame 1, sufficient reinforcing structures can be respectively provided from the first mounting surface 101 and the second mounting surface 102 to strengthen the first mounting plate 12, so that the mounting frame 1 can take into account both lightweight and structural strength.

At least two second mounting holes 14 are used to connect with the rotating shaft 3. Each second mounting hole 14 extends along the second direction B. At least two second mounting holes 14 are respectively located on the first mounting plate 12 and the second mounting plate 13. Among them, the first direction A is perpendicular to the second direction B. The first mounting plate 12, the second mounting plate 13 and the second mounting surface 102 cooperate to form an installation space with an opening and used to accommodate the rotating shaft 3. In this way, on the one hand, the rotating shaft 3 and the connecting member 4 can extend into the installation space from the opening to facilitate installation, and on the other hand, it is also convenient for the mold to be opened along the first direction A during the casting process of the mounting frame 1.

The third mounting plate 21 is arranged at the edge of the second mounting plate 13. The thickness direction of the third mounting plate 21 is parallel to the first direction A. The third mounting plate 21 is used to be fixedly connected to the vehicle body. The projection of the third mounting plate 21 along the first direction A on the first plane does not overlap with the projection of the bottom plate 10 along the first direction A on the first plane. The first plane is perpendicular to the first direction A. As another mounting component of the mounting frame 1, the third mounting plate 21 cooperates with the bottom plate 10 to increase the fixed point and fixed area between the mounting frame 1 and the vehicle body, greatly increasing the stability of the connection between the mounting frame 1 and the vehicle body. In particular, when the mounting frame 1 is fixed to the vehicle body, the third mounting plate 21 can also enhance the structural strength of the second mounting plate 13, so that the second mounting plate 13 also has a reinforcement structure in multiple directions, so that the second mounting plate 13 can adapt to the stress changes of the door during opening or closing. The two projections of the bottom plate 10 and the third mounting plate 21 along the first direction A on the first plane perpendicular to the first direction A do not overlap each other, so that the bottom plate 10 and the third mounting plate 21 can be integrally cast.

The mounting frame 1 in the present disclosure, by reasonably setting the positions of the bottom plate 10, the first mounting plate 12, the second mounting plate 13 and the third mounting plate 21, ensures that the plurality of first mounting holes 11 can have a unified reference for easy installation, and on the other hand, enables the mounting frame 1 to be integrally cast and formed, ensuring that the mounting frame 1 itself has sufficient strength. That is, the mounting frame 1 in the present disclosure has a simple process, high precision and high production efficiency, and by reasonably allocating material distribution on the mounting frame 1, the strength and stability of the parts are improved, and the material utilization rate is improved to achieve a lightweight effect.

It should be noted that, in the above embodiment, the mounting frame 1 shown in FIG1 includes both the bottom plate 10 and the third mounting plate 21. In other embodiments, the mounting frame 1 may also omit the third mounting plate 21. The present disclosure is not limited to this.

Continuing to refer to FIG. 1 , an arc-shaped notch is provided in the middle area of the upper edge of the bottom plate 10 , which reduces the redundant material of the bottom plate 10 , thereby achieving the purpose of enhancing the lightweight effect of the mounting frame 1 without affecting the stability of the mounting frame 1 .

In some embodiments, the mounting frame 1 further includes a first reinforcing plate 15 disposed on the first mounting surface 101. The thickness direction of the first reinforcing plate 15 is perpendicular to the first direction A. The first mounting plate 12 includes a first edge extending along the first direction A. The first reinforcing plate 15 is connected to the first edge. The first reinforcing plate 15 in the present disclosure is connected to the base plate 10 and the first mounting plate 12, so that the mounting points on the base plate 10 and the first mounting plate 12 have a good force transmission path, thereby improving the integrity of the mounting frame 1. The thickness direction of the first reinforcing plate 15 is perpendicular to the first direction A, so that during the casting process of the mounting frame 1 as a whole, the mold can be opened along the first direction A. The thickness direction of the first reinforcing plate 15 can also be perpendicular to the second direction B, so that the mounting frame 1 as a whole is more beautiful.

As an optional embodiment, the first reinforcing plate 15 is provided with an arc-shaped notch. The arc-shaped notch is located in the area of the first reinforcing plate 15 away from the bottom plate 10 and the first mounting plate 12. This arrangement ensures that the first reinforcing plate 15 is securely mounted. The overall strength of the mounting frame 1 is enhanced, while redundant materials are reduced, thereby meeting the requirement of overall lightweight of the mounting frame 1.

In some embodiments, the mounting frame 1 further includes a second reinforcing plate 16 disposed on the first mounting surface 101. The thickness direction of the second reinforcing plate 16 is perpendicular to the first direction A. The first mounting plate 12 includes a second edge disposed opposite to the first edge. The second reinforcing plate 16 is connected to the second edge. The second reinforcing plate 16 in the present disclosure is connected to the base plate 10 and the first mounting plate 12, and cooperates with the base plate 10, the first mounting plate 12 and the first reinforcing plate 15 to form a frame-type structure, which greatly enhances the overall structural strength of the mounting frame 1. The thickness direction of the second reinforcing plate 16 is perpendicular to the first direction A, so that during the casting process of the mounting frame 1 as a whole, the mold can be opened along the first direction A. The thickness direction of the second reinforcing plate 16 can also be perpendicular to the second direction B, making the mounting frame 1 more beautiful as a whole.

As an optional implementation, the second reinforcing plate 16 is provided with an arc-shaped notch.

In some embodiments, the first mounting plate 12 further includes a first notch 120 and a third edge disposed at the opening. The first notch 120 is disposed between the second edge and the third edge to avoid the rotation of the vehicle door. Specifically, the dimension of the mounting frame 1 in the present disclosure along the depth direction of the first direction is smaller than the dimension of the mounting frame 1 in the width direction, and the vehicle door has a first state of closing and a second state of opening. When the vehicle door is in the first state, the vehicle door is perpendicular to the bottom plate 10, that is, the vehicle door is parallel to the depth direction of the mounting frame 1. In the process of switching the vehicle door from the first state to the second state, the vehicle door rotates to be parallel to the width direction of the mounting frame 1. At this time, since the dimension of the mounting frame 1 in the depth direction is smaller than the dimension of the mounting frame 1 in the width direction, it is necessary to avoid the rotation of the vehicle door through the first notch 120 to prevent the first mounting plate 12 from contacting the vehicle door, resulting in the vehicle door being unable to switch to the second state.

Due to the first notch 120 on the first mounting plate 12, the length of the second edge of the first mounting plate 12 is much smaller than the length of the first edge, so that the second reinforcing plate 16 has a deviation in reinforcing effect on the bottom plate 10 and the first mounting plate 12. Therefore, the mounting frame 1 in the present disclosure further includes a reinforcing portion 17. The reinforcing portion 17 is connected and arranged between the second reinforcing plate 16, the first mounting plate 12 and the bottom plate 10.

Continuing to refer to FIG. 1 , in some embodiments, the mounting frame 1 further includes a connecting plate 18 disposed on the second mounting surface 102. The connecting plate 18 is connected and disposed between the first mounting plate 12 and the second mounting plate 13. The thickness direction of the connecting plate 18 is perpendicular to the first direction A. The present disclosure improves the strength of the mounting frame 1 itself by providing the connecting plate 18 to connect one side edge of the first mounting plate 12 and one side edge of the second mounting plate 13. At the same time, the thickness direction of the connecting plate 18 is perpendicular to the first direction A, so that during the casting process of the mounting frame 1, the mold can be opened along the first direction A. The thickness direction of the connecting plate 18 can also be perpendicular to the second direction B, so that the mounting frame 1 is more beautiful as a whole.

When the door is closed, that is, the door switches from the second state to the first state very quickly. Therefore, in order to avoid the door colliding with the mounting frame 1 and making a loud noise when the door is closed, in some embodiments, the mounting frame 1 is provided. The mounting frame 1 further includes a buffer mounting seat 19 disposed on the second mounting surface 102 and a third mounting hole 20 disposed on the buffer mounting seat 19. The third mounting hole 20 extends along the first direction A. The third mounting hole 20 is used to install a buffer block. The buffer block is used to buffer the collision between the vehicle door and the mounting frame 1. The buffer block can be a rubber piece, a sponge pad or other flexible buffer material.

It should be noted that in the conventional welded fixed bracket, since the buffer mounting seat is located inside the fixed bracket, the welding process is difficult and the welding is not firm, resulting in the risk of the buffer mounting seat falling off after long-term use. The buffer mounting seat 19 in the present disclosure is a part of the mounting bracket 1 and is formed by integral casting, which is convenient to cast and very stable.

As an optional embodiment, the buffer mounting seat 19 is connected to the connecting plate 18, that is, the buffer mounting seat 19 is located at the connecting corner of the bottom plate 10 and the connecting plate 18. In this way, the buffer mounting seat 19 can enhance the installation strength of the bottom plate 10 and the connecting plate 18 in addition to being used to install the buffer block.

As an optional embodiment, the buffer mounting seat 19 is a hollow structure. In a conventional welded fixed bracket, if the buffer mounting seat is a hollow structure, the structural complexity of the fixed bracket and the welding difficulty will be greatly increased. However, the mounting bracket 1 in the present disclosure is integrally cast, and only the corresponding structure needs to be added to the mold, which is convenient for molding and can also meet the overall lightweight requirements of the mounting bracket 1.

Since the buffer mounting seat 19 in the present disclosure is used to support the mounting wall of the third mounting hole 20 which is perpendicular to the first direction A, this will cause the mounting frame 1 in the present disclosure to be unable to be cast. Therefore, as an optional embodiment, the base plate 10 includes a second notch (not shown in the figure) corresponding to the buffer mounting seat 19.

In some embodiments, the second mounting plate 13 includes a fifth edge disposed at the opening. The third mounting plate 21 is connected to the fifth edge. A groove for accommodating the mounting bracket 1 is generally disposed on the vehicle body, and the third mounting plate 21 is disposed outside the groove, that is, disposed on the surface of the vehicle body. In this way, the stability of the mounting bracket 1 is further ensured by the installation on different planes.

In some embodiments, the plurality of first mounting holes 11 are arranged in two rows. The two rows of first mounting holes 11 are respectively distributed on the bottom plate 10 and the third mounting plate 21. The second mounting hole 14 is located between the two rows of first mounting holes 11. This arrangement ensures, on the one hand, a uniform distribution of the fixing points of the mounting frame 1, so that the mounting frame 1 is installed more stably, and on the other hand, the installation strength of the rotating shaft 3 is also ensured.

In order to facilitate the installation of the mounting frame 1 , as an optional implementation, part of the first mounting holes 11 on the first mounting surface 101 are enlarged.

In order to meet the lightweight requirements of the mounting frame 1, as an optional embodiment, the third mounting plate 21 A mounting hole 11 is a notch structure.

Continuing to refer to FIG. 1 , the first mounting hole 11 includes a rectangular mounting hole, which can meet the left-right and up-down position adjustment of the door during installation and meet the door installation accuracy requirements. Of course, in other embodiments, the first mounting hole 11 can also be a circle, a polygon, or other shapes, as long as it allows a fastener used to fix the mounting frame 1 to have a certain amount of movement space. The present disclosure is not limited to this.

In some embodiments, the mounting frame 1 further includes a reinforcing rib 22 connected between the first mounting plate 12, the second mounting plate 13 and the bottom plate 10. The thickness direction of the reinforcing rib 22 is perpendicular to the first direction A. The reinforcing rib 22 is located between the two rows of first mounting holes 11. By such an arrangement, the reinforcing rib 22 is close to the second mounting hole 14, thereby improving the structural strength of the mounting frame 1 on the one hand, and ensuring the structural strength of the second mounting hole 14, i.e., the mounting point of the rotating shaft 3, on the other hand.

In some embodiments, the mounting frame 1 is further provided with a third notch 23. The third notch 23 is located at one end of the mounting frame 1 away from the connecting plate 18 to avoid the connecting member 4. When the vehicle door is in the first state, the connecting member 4 is perpendicular to the bottom plate 10. In the process of switching the vehicle door from the first state to the second state, the connecting member 4 rotates in a direction away from the connecting plate 18. At this time, the third notch 23 is used to avoid the rotation of the connecting member 4, so that the mounting frame 1 is prevented from contacting the connecting member 4, resulting in the vehicle door being unable to switch to the second state. Continuing to refer to FIG. 1, since the mounting frame 1 in the present disclosure is integrally cast, the third notch 23 can be conveniently designed as a concave arc surface that fits the rotation curve of the vehicle door.

As an optional embodiment, the mounting frame 1 further includes a third reinforcing plate 25 disposed at the third notch 23. The thickness direction of the third reinforcing plate 25 is perpendicular to the first direction A, and the third reinforcing plate 25 is connected and disposed between the first mounting plate 12, the second mounting plate 13 and the bottom plate 10. In this way, the first mounting plate 12, the second mounting plate 13, the bottom plate 10, the connecting plate 18 and the third reinforcing plate 25 cooperate to form a frame structure, thereby enhancing the structural strength of the mounting frame 1. At the same time, the third reinforcing plate 25 is parallel to the first direction A and the second direction B, so that during the casting process of the mounting frame 1, the mold can be opened along the first direction A.

In some embodiments, the mounting frame 1 further includes a plurality of fourth mounting holes 24 disposed on the first mounting plate 12. The fourth mounting holes 24 extend along the second direction B. The vehicle further includes a drive motor (not shown in the figure) for driving the rotating shaft 3 to rotate. The drive motor is fixedly mounted on the first mounting plate 12 through the plurality of fourth mounting holes 24, and is close to the first mounting surface 101. The drive motor in the present disclosure is disposed on a side of the first mounting plate 12 away from the second mounting plate 13, rather than being disposed between the first mounting plate 12 and the second mounting plate 13, so as to correspond to the first mounting surface 101 and the second mounting surface 102, so that the structural distribution of the mounting frame 1 is more reasonable, and compared with the previous articulated bracket, no additional space is occupied, thereby enhancing the versatility of the mounting frame 1.

In summary, the mounting frame 1 of the present disclosure includes a bottom plate 10 and a third mounting frame 11 in the second direction B, i.e., the longitudinal direction. Plate 21. A plurality of first mounting holes 11 are arranged on the bottom plate 10 and the third mounting plate 21. For example, six first mounting holes 11 are arranged on the bottom plate 10, and two first mounting holes 11 are arranged on the third mounting plate 21, so as to connect the mounting frame 1 to the vehicle body. All the first mounting holes 11 are rectangular structures, which can meet the requirements of up, down, left and right adjustment of the door. One side of the mounting frame 1 is a third notch 23 for avoiding the connecting member 4. Corresponding reinforcement structures are arranged on both sides of the mounting frame 1, and reinforcement ribs 22 are arranged in the middle position of the mounting frame 1. In this way, the mounting frame 1 has multiple rows of fixed points in the upper, middle and lower directions in the longitudinal direction, and multiple reinforcement structures in the left, middle and right directions in the transverse direction. The overall structure of the mounting frame 1 is complete, light in weight, high in rigidity and controllable in precision.

It should be noted that in other embodiments, the thickness directions of the connecting plate 18, the first reinforcing plate 15, the second reinforcing plate 16, the third reinforcing plate 25 and the reinforcing rib 22 in the present disclosure may not be perpendicular to the second direction B, and it is only necessary to ensure that they are perpendicular to the first direction A.

The second aspect of the present disclosure provides a vehicle, including a vehicle body (not shown in the figure), a rotating shaft 3 as shown in Figure 2, a connecting member 4 and a vehicle door (not shown in the figure). The connecting member 4 includes a first end and a second end. The first end is rotatably connected to the vehicle door. The second end is fixedly connected to the rotating shaft 3. The vehicle also includes a mounting frame 1 as described above. The mounting frame 1 is fixed to the vehicle body through a plurality of first mounting holes 11.
