Description

Technical Field

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

[0002] During the development of the trunk lid, a bracket is usually arranged between the inner panel and the outer panel to connect the inner panel and the outer panel to ensure the mechanical properties of the trunk lid. In the prior art, two types of brackets need to be arranged at the same time: one is to weld the inner panel, the outer panel and the bracket together; the other is to weld the bracket to the inner panel first, then apply glue to the bracket and then contact it with the outer panel.

[0003] The coexistence of two types of connection brackets results in a large number of brackets required in the trunk lid. The two types of brackets also need to be installed in different positions of the trunk lid, resulting in the brackets occupying a large space and a complicated installation process, which in turn increases the cost and weight pressure of the trunk lid. Utility Model Content

[0004] The present application provides a trunk cover and a vehicle to solve the above technical problems.

[0005] The embodiment of the present application is implemented as follows:

[0006] A luggage compartment cover includes an inner panel, an outer panel and a bracket, wherein the bracket is connected between the inner panel and the outer panel. The bracket includes a first part and a second part connected to each other, wherein the first part has a first end and a second end, wherein the first end is connected to the outer panel and the second end is connected to the inner panel, and the second part has a third end and a fourth end, wherein the third end is close to the inner panel and connected to the first part, and the fourth end is connected to the outer panel. Thus, the first part of the bracket can be welded or bonded to the inner panel and the outer panel through the first end and the second end, respectively, and the second part of the bracket can be bonded or welded to the outer panel through the fourth end, so that two connection forms can be realized through one bracket, which is beneficial to reducing the number of brackets, simplifying the installation process, and reducing costs and weight pressure.

[0007] In a possible implementation, the outer panel includes a first outer panel and a second outer panel connected to each other; the first end is connected to the first outer panel, and the fourth end is connected to the second outer panel. In this way, the bracket is installed at the connection between the first outer panel and the second outer panel, and the first part and the second part of the bracket simultaneously support the first outer panel, the second outer panel and the inner panel, thereby simplifying the structure and ensuring the connection stability between the inner panel and the outer panel.

[0008] In a possible implementation, a first connecting piece is provided at the first end, the first connecting piece is attached to the first outer panel and is fixedly connected to the first outer panel. A second connecting piece is provided at the fourth end, and the second connecting piece is fixedly connected to the second outer panel. The first connecting piece and the second connecting piece can increase the connection area between the bracket and the first outer panel and the second outer panel, thereby improving the connection reliability.

[0009] In a possible implementation, a groove is provided on one side of the second connecting piece facing the second outer plate, an adhesive is provided in the groove, and the adhesive connects the second outer plate and the second connecting piece. The provision of the groove is conducive to increasing the volume of the adhesive, thereby improving the bonding reliability between the bracket and the second outer plate, and can also locate the position of the adhesive to reduce the displacement of the adhesive.

[0010] In a possible implementation, a support leg is provided on the side of the inner panel facing the outer panel, and the support leg is fixedly connected to the second end. The provision of the support leg can quickly locate and connect the bracket, and can also support the outer panel by connecting the bracket, which is beneficial to improving the overall mechanical properties of the trunk lid.

[0011] In a possible implementation, a third connecting piece is provided at the end of the support leg, and the third connecting piece is attached to the second end and fixedly connected to the second end. The third connecting piece can increase the connection area between the support leg and the bracket, and improve the connection reliability.

[0012] In a possible implementation, the first part and the second part are arranged at an angle, and the angle between the first part and the second part is less than 180°, the third end is connected to the second end, and the connection between the second end and the third end is fixedly connected to the inner panel. In this way, the bracket can support the inner panel and the outer panel from three different directions, thereby improving the overall structural stability of the trunk cover and increasing the mechanical properties of the trunk cover.

[0013] In a possible implementation manner, the bracket further includes a reinforcement structure, which is protruding from the surface of the first part and the second part. The reinforcement structure is beneficial to enhancing the mechanical strength of the bracket and reducing the risk of accidental fracture of the bracket.

[0014] In a possible implementation, there are multiple brackets, and the multiple brackets are spaced and distributed between the inner plate and the outer plate along the width direction of the trunk lid. In this way, the multiple brackets can connect and support the inner plate and the outer plate from different positions, further improving the mechanical performance of the trunk lid.

[0055] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0056] like Figure 1 and Figure 2 As shown, in a prior art, a bracket assembly 30' is connected between the inner plate 10' and the outer plate 20' of the trunk cover 100'. The bracket assembly 30' includes at least one welding bracket 30a, and the two ends of the welding bracket 30a are respectively welded to the inner plate 10' and the outer plate 20'. The bracket assembly 30' includes at least one bonding bracket 30b, and the bonding bracket 30b is first welded to the inner plate 10' and then bonded to the outer plate 20'. The welding bracket 30a and the bonding bracket 30b are separately arranged at different positions of the trunk cover 100', the installation structure is complicated, and the total number of brackets is large, resulting in a large weight and cost pressure on the trunk cover 100'.

[0057] See also Figures 3 to 8 The embodiment of the present application provides a trunk lid 100, comprising an inner panel 10, an outer panel 20 and a bracket 30. The inner panel 10 and the outer panel 20 are arranged opposite to each other along a first direction X, and the outer panel 20 is buckled on the outer side of the inner panel 10. The bracket 30 is connected between the inner panel 10 and the outer panel 20, and can combine two forms of brackets together. The inner panel 10 and the outer panel 20 can be welded and bonded at the same time by one bracket 30, which fully simplifies the installation process, reduces the number of brackets, and achieves the purpose of reducing the cost and weight pressure of the trunk lid 100. Specifically, the bracket 30 includes a first part 31 and a second part 32 connected to each other, the first part 31 has a first end 311 and a second end 312, the first end 311 is connected to the outer panel 20, the second end 312 is connected to the inner panel 10, the second part 32 has a third end 321 and a fourth end 322, the third end 321 is close to the inner panel 10, and the third end 321 is connected to the first part 31, and the fourth end 322 is connected to the outer panel 20. It should be noted that the first end 311 and the second end 312 are end regions at opposite ends of the first portion 31. The third end 321 and the fourth end 322 are end regions at opposite ends of the second portion 32. The connection methods between the first end 311, the second end 312, and the fourth end 322, which are equal to the inner panel 10 or the outer panel 20, include but are not limited to welding, bonding, mechanical locking, and the like.

[0058] In the embodiment of the present application, the first part 31 and the second part 32 of the bracket 30 are both roughly plate-like structures, and the first part 31 and the second part 32 are integrally formed to meet the structural integrity of the bracket 30, reduce the problem of stress concentration on the bracket 30, and improve the mechanical strength of the bracket 30. The molding method of the bracket 30 includes but is not limited to sheet metal, casting, injection molding, etc., and the present application is not limited thereto. It can be understood that in other embodiments, the first part 31 and the second part 32 of the bracket 30 can also be a split structure, and the two parts are fixed together by welding, mechanical connection, etc., which is conducive to reducing the manufacturing difficulty of the bracket 30.

[0059] Furthermore, the first portion 31 and the second portion 32 are arranged at an angle, and the angle between the first portion 31 and the second portion 32 is less than 180°. Figures 3 to 8 In the illustrated embodiment, the extension direction of the first portion 31 intersects with the extension direction of the second portion 32, the third end 321 of the second portion 32 is connected to the second end 312 of the first portion 31, and the connection between the second end 312 and the third end 321 is fixedly connected to the inner panel 10. In this way, the main parts of the first portion 31 and the second portion 32 are generally V-shaped structures, so that when the bracket 30 is connected between the inner panel 10 and the outer panel 20, a triangular support structure is formed to stably support the inner panel 10 and the outer panel 20. In this way, the bracket 30 can support the inner panel 10 and the outer panel 20 from three different directions, improve the overall structural stability of the trunk cover 100, and increase the mechanical properties of the trunk cover 100. A rounded connection structure is also provided between the third end 321 and the second end 312, so that the first portion 31 and the second portion 32 can be connected in a circular arc transition, reduce the stress concentration problem at the bend, and improve the mechanical properties of the bracket 30.

[0060] In the embodiment of the present application, the first end 311 and the second end 312 may be respectively welded to the outer panel 20 and the inner panel 10, and the fourth end 322 may be adhesively connected to the outer panel 20. In other embodiments, the first end 311 and the second end 312 may also be respectively adhesively connected to the outer panel 20 and the inner panel 10, and the fourth end 322 may be welded to the outer panel 20, but the present application is not limited thereto.

[0061] exist Figure 3 In the view angle shown, the first direction X is the thickness direction of the trunk cover 100, which is also the front-rear direction of the vehicle, the second direction Y is the width direction of the trunk cover 100, which is also the left-right direction of the vehicle, and the third direction Z is the height direction of the trunk cover 100, which is also the up-down direction of the vehicle. The first direction X, the second direction Y and the third direction Z are perpendicular to each other, and the positional relationship of each element will be explained in the subsequent embodiments in this coordinate system.

[0062] In some embodiments, Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the outer panel 20 includes a first outer panel 21 and a second outer panel 22 connected to each other. The first outer panel 21 and the second outer panel 22 are distributed up and down along the third direction Z. The first outer panel 21 and the second outer panel 22 can be fixed together by mechanical connection, or can be an integrally formed structure, but the present application is not limited thereto. The extension direction of the first outer panel 21 intersects with the extension direction of the second outer panel 22 to meet the installation requirements of the vehicle. The bracket 30 is installed at the connection between the first outer panel 21 and the second outer panel 22. The first end 311 is connected to the first outer panel 21, and the fourth end 322 is connected to the second outer panel 22. When the second end 312 remains connected to the inner panel 10, the bracket 30 can simultaneously establish a connection relationship with the first outer panel 21, the second outer panel 22 and the inner panel 10, and a relatively small number of brackets are used inside the trunk lid 100 to simultaneously achieve stable support in three different directions of the space, thereby simplifying the structure and ensuring the connection stability between the inner panel 10 and the outer panel 20.

[0063] In some embodiments, there are multiple brackets 30, and along the width direction of the trunk lid 100, which is also the second direction Y, multiple brackets 30 are distributed between the inner panel 10 and the outer panel 20 at intervals. The inner panel 10 may be provided with supporting legs 11 corresponding to the number of the brackets 30, so that the supporting legs 11 can be connected to the brackets 30 one by one. In this way, the multiple brackets 30 can connect and support the inner panel 10 and the outer panel 20 from different positions in the second direction Y, further improving the mechanical properties of the trunk lid 100.

[0064] See also Figure 6 , Figure 7 , Figure 8 and Fig. 9In some embodiments, the first end 311 is provided with a first connecting piece 313, and the first connecting piece 313 is attached to the first outer panel 21 and fixedly connected to the first outer panel 21. The extension direction of the first connecting piece 313 can intersect with the extension direction of the main area of ​​the first part 31, so that the first connecting piece 313 matches the shape of the first outer panel 21 and contacts as much as possible. The welding point 50 between the bracket 30 and the first outer panel 21 can be set on the first connecting piece 313 to fix the first outer panel 21 and the first part 31 of the bracket 30 by welding. The fourth end 322 is provided with a second connecting piece 323, and the second connecting piece 323 is fixedly connected to the second outer panel 22. The extension direction of the second connecting piece 323 can intersect with the extension direction of the main area of ​​the second part 32, so that the second connecting piece 323 matches the shape of the second outer panel 22 and contacts as much as possible. The second connecting piece 323 can be bonded to the second outer panel 22 to fix the bracket 30 and the second outer panel 22. In this way, the first connecting piece 313 and the second connecting piece 323 can increase the connection area between the bracket 30 and the first outer panel 21 and the second outer panel 22, improve the connection reliability, increase the area of ​​the supporting area, and reduce the problem of stress concentration.

[0065] In some embodiments, a groove 33 is further provided on one side of the second connecting piece 323 facing the second outer plate 22, and an adhesive 40 is provided in the groove 33. The adhesive 40 connects the second outer plate 22 and the second connecting piece 323, so that the second portion 32 of the bracket 30 is fixedly connected to the second outer plate 22 by bonding. The provision of the groove 33 is conducive to increasing the accommodating volume of the adhesive 40, thereby improving the bonding reliability between the bracket 30 and the second outer plate 22, and can also locate the position of the adhesive 40 to reduce the displacement of the adhesive 40.

[0066] In other embodiments, in addition to being partially disposed in the groove 33, the adhesive 40 can also be coated on the surface of the second connecting piece 323. The adhesive 40 in the groove 33 and on the surface of the second connecting piece 323 can work together to bond and fix the bracket 30 to the second outer panel 22, further improving the bonding reliability.

[0067] In some embodiments, a support leg 11 is further provided on the side of the inner panel 10 facing the outer panel 20, and the support leg 11 is fixedly connected to the second end 312 to fix the bracket 30 and the inner panel 10. The provision of the support leg 11 can, on the one hand, quickly locate and connect the bracket 30, and on the other hand, can support the outer panel 20 by connecting the bracket 30. The connection between the support leg 11 and the second end 312 is also close to the third end 321, so that the support leg 11 is roughly connected and fixed at the connection between the second end 312 and the third end 321. A Y-shaped support structure is roughly formed between the support leg 11, the first part 31 and the second part 32 of the bracket 30, and stable support in three directions is achieved through a simple structure, further improving the overall mechanical properties of the trunk lid 100.

[0068] In some embodiments, a third connecting piece 12 is further provided at the end of the support leg 11 away from the inner panel 10, and the third connecting piece 12 fits the second end 312 and is fixedly connected to the second end 312. The extension direction of the third connecting piece 12 can intersect with the extension direction of the main area of ​​the support leg 11, so that the third connecting piece 12 matches the shape of the first part 31 and contacts as much as possible. The third connecting piece 12 can increase the connection area between the support leg 11 and the bracket 30, and improve the connection reliability. The welding point 50 between the bracket 30 and the inner panel 10 can be set on the third connecting piece 12 to fix the inner panel 10 and the first part 31 of the bracket 30 by welding. In other embodiments, the third connecting piece 12 can also be fixedly connected to the first part 31 by mechanical locking.

[0069] In some embodiments, Fig. 9 As shown, the bracket 30 also includes a reinforcing structure 34, which is convexly arranged on the surface of the first part 31 and the second part 32. Specifically, the reinforcing structure 34 is approximately located at the midline position of the bracket 30, and can be a reinforcing rib structure convexly arranged on the surface of the bracket 30, formed by sheet metal or the like. The reinforcing structure 34 on the surface of the first part 31 and the reinforcing structure 34 on the surface of the second part 32 are connected as a whole. The surfaces of the first connecting piece 313 and the second connecting piece 323 are not provided with the reinforcing structure 34 to maintain the flatness of the connecting surface. The provision of the reinforcing structure 34 is conducive to enhancing the mechanical strength of the bracket 30 and reducing the risk of accidental breakage of the bracket 30.

[0070] Furthermore, the bracket 30 is also provided with a through hole 35. In the embodiment of the present application, two through holes 35 are provided on the first part 31 and are symmetrically arranged on both sides of the reinforcing structure 34. The provision of the through holes 35 can reduce the weight of the bracket 30 on the one hand, and provide connection sites for the installation of other components on the other hand, meeting various installation requirements. In other embodiments, the number of through holes 35 can also be one or more than two, and the through holes 35 can also be provided on the second part 32, as long as the actual installation requirements are met. The present application does not limit the number and position of the through holes 35.

[0071] See also Fig.10 An embodiment of the present application further provides a vehicle 200 , comprising a vehicle body 201 and a trunk lid 100 as described in the above embodiment or combination of embodiments, wherein the trunk lid 100 is installed on the vehicle body 201 .
