Description

Technical Field

[0001] The present application relates to the technical field of vehicle parts, and in particular to a trunk lid structure suitable for a painting jig. Background Art

[0002] During the production of automobiles, especially three-box sedans, the painting and coloring of the car body is completed in an electrophoretic tank through a coating process. After the car body enters the tank, its trunk lid must maintain a certain degree of opening, so that during the electrophoretic treatment before painting, the tank liquid can quickly reach the inner cavity of the car body and react chemically with the car body sheet, thereby achieving the film thickness requirement of electrophoretic anti-corrosion. In order to reduce the space occupied by the coating equipment, in the current coating process, the trunk lid is usually fixed and kept open to a limited extent by a coating limiting jig. Generally speaking, the coating jig has three fixed ends, that is, the coating jig and the trunk lid are fixed through three fixed points, wherein the first fixed end is fixedly connected to the center of the inner side of the trunk lid, and the second fixed end and the third fixed end are respectively fixedly connected to the two sides of the inner side of the trunk lid near the rear of the vehicle.

[0003] The existing design for the trunk lid attachment to a painting jig generally follows this approach: the first fixing point is located on the trunk lid's inner panel or lock reinforcement plate, where the sheet metal is a single layer; the second and third fixing points are also located on the trunk lid's inner panel. This approach has the following drawbacks: the single-layer sheet metal structure is relatively weak and prone to deformation; the trunk lid's inner panel is relatively thin, lacking strength and also prone to deformation; the second and third fixing points are far apart, resulting in the associated painting jig occupying a large space and making it difficult to operate; and the painting jig is heavy, resulting in high production costs. Summary of the Invention

[0004] (1) Technical issues to be resolved

[0005] The first purpose of this application is to provide a trunk lid structure suitable for a painting jig that can effectively improve the fixing method of the trunk lid and the painting jig, so as to solve the problems of unstable fixed connection between the trunk lid and the painting jig, large space occupation and inconvenient operation caused by the unreasonable position of the fixing point in the prior art.

[0006] The second purpose of this application is to provide a vehicle that can effectively improve the fixing method of the trunk lid and the painting jig, so as to solve the problems of unstable fixed connection between the trunk lid and the painting jig, large space occupation and inconvenient operation caused by the unreasonable position of the fixing point in the prior art.

[0007] (2) Technical solution

[0008] In order to solve the above technical problems, on the one hand, the present application provides a trunk lid structure suitable for a painting jig, comprising: an inner panel; a lock reinforcement plate, which comprises a reinforcement plate body fixedly arranged on the outer side of the inner panel, and a reinforcement portion extending from the reinforcement plate body to the inner side of the inner panel; and an outer panel covering the inner panel and the lock reinforcement plate; wherein a first fixing point is commonly provided on the inner panel and the reinforcement plate body, a second fixing point and a third fixing point are provided on the reinforcement portion, the inner panel and the reinforcement plate body are fixedly connected to the painting jig through the first fixing point, and the reinforcement portion is fixedly connected to the painting jig through the second fixing point and the third fixing point.

[0009] Optionally, the thickness of the inner plate is smaller than the thickness of the lock reinforcement plate.

[0010] Optionally, the first fixing point, the second fixing point and the third fixing point are all fixing holes.

[0011] Optionally, the outer side of the inner panel is in contact with the reinforcing panel body at a first fixing point.

[0013] Optionally, the painting jig is fixedly connected to the inner plate and the reinforcement plate body at the first fixing point by fixing bolts and fixing nuts.

[0014] Optionally, the painting jig is fixedly connected to the reinforcement portion at the second fixing point and the third fixing point by fixing bolts and fixing nuts.

[0015] Optionally, the first fixing point is located at the central axis of the inner plate, and the first fixing point, the second fixing point and the third fixing point are distributed in an isosceles triangle.

[0016] On the other hand, the present application further provides a vehicle, which includes the trunk lid structure suitable for the painting jig as described above.

[0017] (3) Beneficial effects

[0018] The above technical solution of this application has the following advantages:

[0019] The present application provides a trunk lid structure suitable for a painting jig, comprising an inner panel; a lock reinforcement plate fixedly mounted on the inner panel; and an outer panel; wherein the inner panel and the lock reinforcement plate are jointly provided with a first fixing point, and the lock reinforcement plate is provided with a second fixing point and a third fixing point, the inner panel and the lock reinforcement plate are fixedly connected to the painting jig via the first fixing point, and the lock reinforcement plate is fixedly connected to the painting jig via the second fixing point and the third fixing point.

[0020] The metal plate at the first fixing point is set to be double-layer, including the inner plate and the reinforcement plate body of the lock reinforcement plate, replacing the single-layer sheet metal design in the prior art, and the second fixing point and the third fixing point are set on the reinforcement part of the lock reinforcement plate with a larger thickness, thereby improving the fixing strength.

[0021] The position of the first fixing point is moved vertically upward, and the positions of the second and third fixing points are moved laterally inward, so that the first fixing point, the second fixing point, and the third fixing point are distributed in an isosceles triangle with relatively similar side lengths. This improves the stability of the fixed connection between the trunk lid and the painting jig, reduces the space occupied by the painting jig, thereby reducing the weight and production cost of the painting jig, and improving the operating comfort of the operator.

[0029] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] In the description of this application, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting this application. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the present application, when the trunk lid is fixedly connected to the painting jig, when the observer faces the trunk lid from the side of the painting jig, the direction facing forward by the observer is the outside, and vice versa is the inside. The direction in which the observer looks left and right is the X direction, and the direction in which the observer looks up and down is the Y direction, which is equivalent to the upward viewing direction when the trunk lid is installed in the closed state on the vehicle.

[0032] Figure 1a 、 1b It is a schematic diagram of the trunk lid structure according to two prior arts.

[0033] Reference Figure 1a and Figure 3 The trunk lid 1 is connected to the painting jig 2 via three fixing points, wherein the upper fixing point, namely the first fixing point 100, is located on the inner panel 11 and is substantially located in the middle of the trunk 1 in the X direction; the two lower fixing points, namely the second fixing point 200 and the third fixing point 300, are also located on the inner panel 11 and are symmetrically arranged in the Y direction. Figure 2a It can be seen that the metal plate at the first fixing point 100 is a single layer, namely the inner plate 11 .

[0034] Reference Figure 1b and Figure 3 The trunk lid 1 is connected to the painting jig 2 through three fixing points, wherein the upper fixing point, namely the first fixing point 100, is located on the lock reinforcement plate 12 and is basically located in the middle of the trunk 1 in the X direction; the two lower fixing points, namely the second fixing point 200 and the third fixing point 300, are located on the inner plate 11 and are arranged symmetrically about the Y direction. Figure 2b It can be seen that the metal plate at the first fixing point 100 is a single layer, namely the lock reinforcement plate 12 .

[0035] Regarding the above trunk lid design, on the one hand, at the first fixing point 100, the trunk lid 1 and the painting jig 2 are fixed only by a single layer of metal plate (inner plate 11 or lock reinforcement plate 12). Due to insufficient thickness, the metal plate is easily deformed, making the fixed connection unstable, thereby increasing the difficulty of operation for the operator; on the other hand, the second fixing point 200 and the third fixing point 300 are far apart, which not only affects the stability, but also increases the occupied space of the matching painting jig 2 and increases production costs.

[0036] Figure 4 and Figure 6 It is a schematic diagram of a trunk lid structure suitable for a painting jig according to the present application.

[0037] like Figure 4 and Figure 6 The trunk lid structure shown includes: an inner panel 11; a lock reinforcement plate 12, which includes a reinforcement plate body 121 fixedly arranged on the outer side of the inner panel 11, and a reinforcement portion 122 extending from the reinforcement plate body 121 to the inner side of the inner panel 11; and an outer panel 13, covering the inner panel 11 and the lock reinforcement plate 12; wherein, a first fixing point 100 is commonly provided on the inner panel 11 and the reinforcement plate body 121, and a second fixing point 200 and a third fixing point 300 are provided on the reinforcement portion 122, the inner panel 11 and the reinforcement plate body 121 are fixedly connected to the painting jig 2 through the first fixing point 100, and the reinforcement portion 122 is fixedly connected to the painting jig 2 through the second fixing point 200 and the third fixing point 300.

[0038] According to an embodiment of the present application, the thickness of the inner plate 11 is smaller than the thickness of the lock reinforcement plate 12 .

[0039] According to an embodiment of the present application, the first fixing point 100 , the second fixing point 200 , and the third fixing point 300 are all fixing holes.

[0040] According to an embodiment of the present application, the outer side of the inner panel 11 is in contact with the reinforcing panel body 121 at the first fixing point 100 .

[0041] According to an embodiment of the present application, the inner side of the inner panel 11 is in contact with the edge of the reinforcement portion 122 .

[0042] According to an embodiment of the present application, the painting jig 2 is fixedly connected to the inner plate 11 and the reinforcing plate body 121 at the first fixing point 100 by fixing bolts (not shown in the figure) and fixing nuts 14 .

[0043] According to an embodiment of the present application, the painting jig 2 is fixedly connected to the reinforcement portion 122 at the second fixing point 200 and the third fixing point 300 by fixing bolts (not shown in the figure) and fixing nuts 14 .

[0044] According to an embodiment of the present application, the first fixing point 100 is located at the central axis of the inner panel 11 , and the first fixing point 100 , the second fixing point 200 , and the third fixing point 300 are distributed in an isosceles triangle.

[0045] In a specific embodiment, the thickness of the inner panel 11 of the automobile trunk lid is designed to be 0.65 mm, and the thickness of the lock reinforcement plate 12 is designed to be 1.15 mm. If the trunk lid structure of the prior art is used to fix the trunk lid 1 to the painting jig 2, the thickness of the metal plate at the first fixing point 100 is 0.65 mm (when the first fixing point 100 is located on the inner panel 11) or 1.15 mm (when the first fixing point 100 is located on the lock reinforcement plate 12). Figure 3 The thickness of the metal plate at the second fixing point 200 and the third fixing point 300 is 0.65 mm (ie, the thickness of the inner plate 11, as shown); Figure 3 By using the trunk lid structure of the present application, the thickness of the metal plate at the first fixing point 100 is the sum of the thickness of the inner plate 11 and the lock reinforcement plate 12, that is, 1.80 mm (as shown). Figure 5 、 Figure 6 The thickness of the metal plate at the second fixing point 200 and the third fixing point 300 is 1.15 mm (ie, the thickness of the lock reinforcement plate 12, as shown); Figure 5 、 Figure 6 As shown in the figure, the thickness of the metal plates at the three fixing points has been significantly increased, making the fixation of the trunk lid and the painting jig more reliable.

[0046] The first fixing point 100 is set at the central axis of the inner panel 11 and is appropriately moved upward along the Y direction, so that the first fixing point 100, the second fixing point 200 and the third fixing point 300 are distributed in an isosceles triangle with similar three-side lengths. When the trunk lid 1 is connected to the painting jig 2, the force distribution of the three fixing points is more uniform, the painting jig 2 occupies less space, and the operation comfort is better.

[0047] The present application also provides a vehicle including the trunk lid structure suitable for the painting jig described in the above embodiments.

[0048] In summary, the present application provides a trunk lid structure suitable for a painting jig, comprising: an inner panel; a lock reinforcement plate, comprising a reinforcement plate body fixedly disposed on the outer side of the inner panel, and a reinforcement portion extending from the reinforcement plate body to the inner side of the inner panel; and an outer panel covering the inner panel and the lock reinforcement plate; wherein a first fixing point is commonly provided on the inner panel and the reinforcement plate body, and a second fixing point and a third fixing point are provided on the reinforcement portion; the inner panel and the reinforcement plate body are fixedly connected to the painting jig via the first fixing point, and the reinforcement portion is fixedly connected to the painting jig via the second fixing point and the third fixing point. As a result, the improved trunk lid structure improves the stability of the trunk lid when fixedly connected to the painting jig, and reduces the space occupied by the painting jig, thereby reducing the weight and production cost of the painting jig and improving the operating comfort of the operator.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
