Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle body side wall installation auxiliary equipment structure, in particular to a pressing mechanism for the outer skin of a vehicle side wall. Background Art

[0002] The side panels of a car refer to the skirt formed by the front and rear bumpers of the car. They are spoilers on the outside of the car body. The main function of the side panels of a car is to reduce the reverse airflow generated when the car is driving and increase the downforce of the car, making the car more stable when driving at high speeds. The outer skin of the side panels of a car is mainly used to protect and decorate the side panels of the car.

[0003] Under the background of fierce competition in the current automobile market, the design and manufacture of automobile side panels and their outer skins pay more and more attention to the aesthetic, coordinated and personalized appearance while ensuring functionality and safety. In the prior art, a pressing mechanism is generally used to install the side panel outer skin; the pressing mechanism includes a pressing component and a suction cup component, the pressing component presses the side panel outer skin along the four sides of the side panel outer skin, and the suction cup component provides downward force from the bottom to the joint of the front and rear sections of the side panel outer skin, thereby ensuring that the two sections of the front and rear joints of the side panel outer skin are aligned and kept flat.

[0004] However, for some large vehicles, the joint gap between the front and rear sections of their side panel outer skin is relatively long, which makes it difficult for the clamping mechanism in the prior art to ensure that the front and rear sections of the side panel outer skin are flat and aligned after installation. That is, after the front and rear sections of the side panel are installed, surface differences are prone to occur, affecting the overall aesthetics of the car. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a clamping mechanism for the side panel skin of an automobile, which is used to solve the problem in the prior art that for large vehicles, surface difference is easily generated when the front and rear sections of the side panel outer skin are spliced, thereby affecting the overall appearance of the automobile.

[0006] To achieve the above-mentioned purpose and other related purposes, the utility model provides a clamping mechanism for a side panel skin of an automobile, comprising a mounting frame and a clamping assembly, the clamping assembly comprising a circumferential clamping component and a clamping component at a joint; the circumferential clamping component presses the four sides of the side panel outer skin onto the mounting frame; the side panel outer skin comprises a rear section skin and a front section skin, the clamping component at the joint presses the spliced ​​ends of the rear section skin and the front section skin onto the mounting frame; the clamping component at the joint comprises a clamping arm, the two ends of the clamping arm are clamped at the two ends of the splicing; the shape of the clamping arm is the same as the shape of the splicing, a plurality of clamping blocks are installed at the lower part of the clamping arm, each of the clamping blocks simultaneously clamps the spliced ​​ends of the rear section skin and the front section skin.

[0007] Optionally, the pressing block includes a rear pressing block and a front pressing block, and the rear pressing block and the front pressing block are separately arranged; the rear pressing block presses the splicing end of the rear section skin onto the mounting frame, and the front pressing block presses the splicing end of the front section skin onto the mounting frame.

[0008] Optionally, the clamping component at the joint further includes an end pressure arm; one end of the end pressure arm is fixedly connected to the circumferential clamping component, and the other end is fixedly connected to the end of the clamping arm.

[0009] Optionally, the clamping component at the joint also includes a pressure arm at the turning point; the joint has a turning point, the clamping arm turns along with the turning point of the joint, and the two ends of the pressure arm at the turning point are respectively fixedly connected to the two sections of the clamping arm at the turning point.

[0010] Optionally, the end of the clamping arm is fixedly mounted on the circumferential clamping component through a positioning hole.

[0011] Optionally, a handle is installed on the clamping arm.

[0012] Optionally, the clamping assembly further includes a suction cup component, which is mounted on the mounting frame; the suction cup component applies downward suction to the splicing end of the rear section skin and the splicing end of the front section skin.

[0013] Optionally, a weight-reducing hole is provided on the clamping arm.

[0014] As described above, the clamping mechanism for the outer skin of the side panel of an automobile of the utility model has at least the following beneficial effects:

[0015] 1. The clamping mechanism of the outer skin of the side panel of the automobile is clamped at the two ends of the splicing part by the two ends of the clamping arm; the shape of the clamping arm is the same as the shape of the splicing part, and a plurality of clamping blocks are installed at the lower part of the clamping arm, and each clamping block simultaneously clamps the splicing ends of the rear section skin and the front section skin. Compared with the design of the prior art using a device such as a suction cup to apply downward force to the rear section skin and the front section skin, the clamping arm with the same shape as the splicing part and the plurality of clamping blocks can more fully ensure that the splicing end of the rear section skin and the splicing end of the front section skin are aligned on the same plane; there will be no device such as a suction cup in the prior art, because of the different positions and the difference in suction force of different suction cups, so that the splicing ends of the two sections of skin are subjected to different forces, which ultimately causes the splicing part of the rear section skin and the front section skin to be misaligned, resulting in surface difference, affecting the overall appearance of the vehicle.

[0016] 2. The clamping mechanism of the outer skin of the side panel of the present automobile comprises a rear clamping block and a front clamping block through a clamping block. The rear clamping block and the front clamping block are separately arranged. The rear clamping block presses the splicing end of the rear section of the skin on the mounting frame, and the front clamp presses the splicing end of the front section of the skin on the mounting frame. This design not only ensures that the splicing ends of the two sections of the skin can be aligned on the same plane, but also the separately arranged rear clamping block and front clamping block are convenient for operators to adjust the rear section of the skin and the front section of the skin during the installation process, thereby further improving work efficiency and ensuring the installation quality of the outer skin of the side panel.

[0017] 3. The clamping mechanism of the side panel outer skin of the automobile also includes an end pressure arm through the clamping component at the joint. One end of the end pressure arm is fixedly connected to the circumferential clamping component, and the other end is fixedly connected to the end of the clamping arm. When the circumferential clamping component is working to clamp the circumference of the side panel outer skin, the clamping blocks on the clamping arm are driven together to clamp the clamping ends of the rear section of the skin and the front section of the skin, so that the circumferential clamping component and the clamping component at the joint share a power device, which not only saves the installation space of the entire mechanism, but also ensures that the circumference and the joint of the side panel outer skin are subjected to the clamping force at the same time, that is, further ensures the flatness of the side panel outer skin and improves the overall appearance of the vehicle.

[0018] 4. The clamping mechanism of the outer skin of the side panel of the automobile also includes a pressure arm at the turning point through the clamping components at the joint; there is a turning point at the joint of the two sections of the skin, and the clamping arm turns along with the turning point of the joint, and the two ends of the pressure arm at the turning point are respectively fixedly connected to the two sections of the clamping arm at the turning point. This design ensures that when there is a turning point at the joint of the outer skin of the side panel of the vehicle, the clamping mechanism can still press and align the rear section of the skin and the front section of the skin to ensure that there is no surface difference between the two, that is, to ensure the overall appearance of the vehicle.

[0019] 5. The clamping mechanism of the automobile side panel outer skin also includes a suction cup component through a clamping assembly, and the suction cup component is installed on a mounting frame; the suction cup component is designed to apply downward suction to the splicing ends of the rear section skin and the splicing ends of the front section skin, and the device for eliminating the surface difference at the splicing of the side panel outer skin in the prior art is combined with the clamping mechanism, which further ensures the appearance quality of the rear section skin and the front section skin after they are assembled together when the design is in use.

[0026] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0027] See also Figure 1 and Figure 2The utility model provides a clamping mechanism for a side panel skin of an automobile. Like most designs in the prior art, the clamping mechanism includes a mounting frame 2 and a clamping assembly. The design point of the clamping mechanism is that the clamping assembly includes a circumferential clamping component 3 and a joint clamping component 4. The side panel skin includes a rear section skin 11 and a front section skin 12. The circumferential clamping component 3 clamps the periphery of the side panel skin against the mounting frame 2, while the joint clamping component 4 clamps the rear section skin 11 and the front section skin 12. The spliced ​​end of the front section skin 12 is pressed against the mounting frame 2; the clamping component 4 at the splicing is not composed of a suction cup-like device as in the prior art, but is based on a clamping arm 41, with both ends of the clamping arm 41 pressed against the two ends of the splicing; the shape of the clamping arm 41 is the same as the shape of the splicing, and a plurality of clamping blocks 42 are installed at the lower part of the clamping arm 41, and each of the clamping blocks 42 simultaneously presses the splicing ends of the rear section skin 11 and the front section skin 12. Compared with the design of the prior art using devices such as suction cups to apply downward force to the rear section skin 11 and the front section skin 12, the clamping arm 41 with the same shape as the splicing part and a plurality of clamping blocks 42 can more fully ensure that the splicing end of the rear section skin 11 and the splicing end of the front section skin 12 are aligned on the same plane; there will be no devices such as suction cups in the prior art, which will cause different forces on the splicing ends of the two sections of the skin due to the different positions and the difference in suction force of different suction cups, and ultimately cause the splicing part of the rear section skin 11 and the front section skin 12 to be misaligned, resulting in surface difference, affecting the overall appearance of the vehicle.

[0028] In another embodiment, see Figure 1 and Figure 2 The clamping block 42 includes a rear clamping block 421 and a front clamping block 422, which are separately arranged; the rear clamping block 421 presses the splicing end of the rear section skin 11 onto the mounting frame 2, and the front clamping block 422 presses the splicing end of the front section skin 12 onto the mounting frame 2. The design of this embodiment not only ensures that the splicing ends of the two sections of the skin can be aligned on the same plane, but also the separately arranged rear clamping block 421 and the front clamping block 422 are also convenient for operators to adjust the rear section skin 11 and the front section skin 12 during the installation process, thereby further improving work efficiency and ensuring the installation quality of the side outer skin.

[0029] In another embodiment, see Figure 2The clamping component 4 at the joint also includes an end pressure arm 43; one end of the end pressure arm 43 is fixedly connected to the circumferential clamping component 3, and the other end is fixedly connected to the end of the clamping arm 41. When the circumferential clamping component 3 is working to clamp the circumference of the side outer skin, it drives the clamping block 42 on the clamping arm 41 to clamp the clamping end of the rear section skin 11 and the clamping end of the front section skin 12, so that the circumferential clamping component 3 and the clamping component 4 at the joint share a power device, which not only saves the installation space of the entire mechanism, but also ensures that the circumference and the joint of the side outer skin are subjected to the clamping force at the same time, that is, further ensures the flatness of the side outer skin and improves the overall appearance of the vehicle.

[0030] In another embodiment, see Figure 2 The clamping component 4 at the joint also includes a pressure arm 44 at the turning point; the joint has a turning point, and the clamping arm 41 turns along with the turning point of the joint, and the two ends of the pressure arm 44 at the turning point are respectively fixedly connected to the two sections of the clamping arm 41 at the turning point. The design of this embodiment ensures that when there is a turning point at the joint of the outer skin of the vehicle side panel, the clamping mechanism can still press and align the rear section skin 11 and the front section skin 12 to ensure that there is no surface difference between the two, that is, to ensure the overall appearance of the vehicle.

[0031] In another embodiment, see Figure 2 The pressure arm 44 at the turning point is composed of two pressure arms, which is convenient for the operator to make real-time adjustments according to actual production conditions.

[0032] In another embodiment, see Figure 1 and Figure 2 The end of the clamping arm 41 is fixedly mounted on the circumferential clamping component 3 through a positioning hole. Compared with the design of connecting the end pressure arm 43 and the circumferential clamping component 3 in the previous embodiment, the connection method of this embodiment is simpler and the installation and disassembly are more convenient.

[0033] In another embodiment, see Figure 2 A handle 45 is installed on the clamping arm 41 to facilitate the operator to properly adjust the clamping component 4 at the joint when producing the side panel outer skin.

[0034] In another embodiment, see Figure 1 The clamping assembly also includes a suction cup component, which is installed on the mounting frame 2; the suction cup component applies downward suction to the splicing end of the rear skin section 11 and the splicing end of the front skin section 12; the design of this embodiment combines the device for eliminating the surface difference at the splicing of the side outer skin in the prior art with the clamping mechanism, which further ensures the appearance quality of the rear skin section 11 and the front skin section 12 after they are assembled together when the design is in use.

[0035] In another embodiment, the clamping assembly further includes a gasket, which can be inserted into the gap between the clamping block 42 and the outer skin of the side enclosure according to actual production conditions, thereby improving the applicability of the clamping mechanism.

[0036] In other embodiments, Figure 2 As shown, the clamping arm 41 is provided with a weight-reducing hole, which saves materials and reduces the workload of operators.

[0037] In summary, the utility model clamps the two ends of the splicing part by the two ends of the clamping arm 41; the shape of the clamping arm 41 is the same as the shape of the splicing part, and a plurality of clamping blocks 42 are installed at the lower part of the clamping arm 41, and each clamping block 42 simultaneously clamps the splicing ends of the rear section skin 11 and the front section skin 12. Compared with the design of the prior art that uses a device such as a suction cup to apply a downward force to the rear section skin 11 and the front section skin 12, the clamping arm 41 with the same shape as the splicing part and the plurality of clamping blocks 42 can more fully ensure that the splicing ends of the rear section skin 11 and the front section skin 12 are aligned on the same plane; there will be no device such as a suction cup in the prior art, which will cause the splicing of the two sections of the skin to be different due to the different positions and the difference in suction force of different suction cups. The forces on the joint ends are different, which eventually causes the splicing of the rear skin 11 and the front skin 12 to be misaligned, resulting in surface difference, which affects the overall appearance of the vehicle; at the same time, the clamping block 42 includes a rear clamping block 421 and a front clamping block 422, and the rear clamping block 421 and the front clamping block 422 are separately arranged, and the rear clamping block 421 presses the splicing end of the rear skin 11 on the mounting frame 2, and the front clamping block 422 presses the splicing end of the front skin 12 on the mounting frame 2. The design not only ensures that the splicing ends of the two skins can be aligned on the same plane, but also the separately arranged rear clamping block 421 and the front clamping block 422 are convenient for operators to adjust the rear skin 11 and the front skin 12 during the installation process, which further improves the work efficiency and ensures the installation quality of the side outer skin. Therefore, the utility model effectively overcomes the shortcomings of the prior art and has a high industrial utilization value.

Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
