[0030] The tailgate is an important component of the car. The tailgate is also the trunk of the car. The driver and passengers can open and close the tailgate manually, by pressing the tailgate key or by pressing the remote control car key, and can easily and quickly store objects in the vehicle. Due to the structural limitations of the tailgate shape and stop arrangement, a large cavity is formed in the middle and lower part of the back door, making the strength of this area weak. When pressing this area, the tailgate is easily deformed due to the insufficient dent resistance of the outer panel, which in turn affects the normal use of the tailgate.

[0031] Therefore, a reinforcement plate needs to be installed between the inner and outer panels of the back door to prevent the above problems. However, the conventional reinforcement plate is usually made of sheet metal material, which has a low utilization rate and increases the weight of the entire back door.

[0032] In view of this, the embodiment of the utility model provides a car tailgate and a vehicle, wherein the density of the inner panel is less than that of the support member, and / or the density of the outer panel is less than that of the support member, and under the same volume, the weight of the support member is smaller, which effectively reduces the overall weight of the car tailgate. In addition, the support member replaces the use of sheet metal parts, reduces the use of sheet metal materials, and effectively improves the utilization rate of sheet metal materials; compared with sheet metal parts, the support member has a simpler structure and a lower space occupancy rate, and can reserve more installation space for other components.

[0033] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0034] like Figure 1-Figure 5 As shown, an embodiment of the utility model provides a car tailgate, which includes an inner panel 10, an outer panel 20 and a support member 30. The inner panel 10 and the outer panel 20 are arranged at intervals. The support member 30 is arranged between the inner panel 10 and the outer panel 20 and connects the inner panel 10 and the outer panel 20. The density of the inner panel 10 and / or the density of the outer panel 20 are respectively less than the density of the support member 30.

[0035] In the technical solution adopted in this embodiment, the inner panel 10 and the outer panel 20 are connected by the support member 30, which can improve the connection strength of the inner panel 10 and the outer panel 20, and can also provide support at the interval between the inner panel 10 and the outer panel 20, enhance the anti-dent performance of the outer panel 20, and prevent the outer panel 20 from collapsing and deforming due to extrusion. Moreover, the density of the inner panel 10 is less than that of the support member 30, and / or the density of the outer panel 20 is less than that of the support member 30. Under the same volume, the weight of the support member 30 is smaller, which effectively reduces the overall weight of the car tailgate. In addition, the support member 30 replaces the use of sheet metal parts, reduces the use of sheet metal materials, and effectively improves the utilization rate of sheet metal materials; compared with sheet metal parts, the support member 30 has a simpler structure and a lower space occupancy rate, and can reserve more installation space for other components.

[0036] Specifically, the tailgate of the automobile includes an inner panel 10 and an outer panel 20, and the inner panel 10 and the outer panel 20 are usually made of sheet metal materials, so that the structural strength of the tailgate of the automobile can be improved. However, during the production process of the tailgate of the automobile, due to structural limitations such as the shape of the tailgate or the arrangement of the stopper, a larger cavity will be formed in the middle and lower part of the tailgate. It can be understood that at this time, there is a large spacing between the inner panel 10 and the outer panel 20. Due to the existence of the cavity, the strength of the tailgate of the automobile in this area is relatively weak. When pressing this area, the outer panel 20 or the inner panel 10 is not dent-resistant enough, and it is easy to dent toward the inside of the cavity, thereby causing the tailgate of the automobile to deform, and further affecting the appearance and normal use of the tailgate of the automobile. For this reason, a support member 30 is provided in this embodiment, and the inner panel 10 and the outer panel 20 are connected by the support member 30, which effectively provides support and dent-resistant performance to prevent the deformation of the tailgate of the automobile. Moreover, the density of the inner panel 10 is smaller than that of the support member 30, and / or the density of the outer panel 20 is smaller than that of the support member 30. Under the same volume, the weight of the support member 30 is smaller, which effectively reduces the overall weight of the car tailgate. In other words, the material of the support member 30 is different from the sheet metal material used for the inner panel 10 and the outer panel 20. Compared with the sheet metal material, the support member 30 has better conformability and can be smaller in size, which effectively improves the utilization rate of the material. As an optional method, the support member 30 in this embodiment can be made of plastic, which can not only meet the requirements of support and anti-dent, but also reduce weight and save costs. Of course, in other embodiments, the support member 30 can also use other materials that can achieve the same effect, which is not limited here. As an optional method, refer to Figure 3 and Figure 4 The support member 30 is provided with a hollow structure 32, which can further reduce the weight of the support member 30, thereby reducing the overall weight of the automobile tailgate. Optionally, the hollow structure 32 is a weight-reducing hole, and a plurality of weight-reducing holes are provided at intervals along the width direction of the vehicle.

[0037] In one embodiment, the outer panel 20 or the inner panel 10 can be fixedly connected to the support member 30, such as by laser welding, etc., so as to improve the reliability of the connection and ensure the anti-dent performance. Of course, the outer panel 20 or the inner panel 10 can also be detachably connected to the support member 30, such as by snap connection, screw connection, etc., so as to improve the convenience of disassembly and assembly of the support member 30. Moreover, the support member 30 of the corresponding material can be replaced according to different anti-dent performance.

[0038] Exemplarily, in one embodiment of the utility model, the support member 30 is bonded to the outer panel 20 by an adhesive. Specifically, the outer panel 20 and the support member 30 are usually connected by an adhesive, which can avoid punching holes or setting other fixing structures on the outer panel 20, can reduce the complexity of the structure, and can also reduce the adverse effects on the dent resistance of the outer panel 20, and further prevent the deformation of the car tailgate. As an optional method, the adhesive can be glue, self-adhesive stickers, etc., which are not limited here. In one embodiment, the adhesive is an expansion glue. After the car tailgate is painted and baked, the expansion glue will expand, thereby improving the connection reliability between the inner panel 10 and the outer panel 20. Moreover, the expansion glue is a soft glue, which can reduce the extrusion of the outer panel 20 and prevent damage to the outer panel 20 compared with hard glue.

[0039] Exemplarily, in one embodiment of the utility model, the surface area of ​​the end of the support member 30 facing the outer panel 20 is greater than the surface area of ​​the end of the support member 30 facing the inner panel 10. In this way, the glue coating area of ​​the end of the support member 30 close to the outer panel 20 can be increased, and more adhesive can be applied, thereby improving the bonding reliability of the support member 30 and the outer panel 20. Moreover, the end of the support member 30 facing the inner panel 10 is mechanically connected to the inner panel 10, which can reduce the size, thereby saving the use of materials, further reducing the weight of the support member 30, and thereby reducing the overall weight of the car tailgate. As an optional method, the overall thickness of the support member 30 is equal, and the lengths of the two ends are different, where the length refers to the size along the width direction of the vehicle. It can be understood that the size of the end of the support member 30 facing the outer panel 20 along the width direction of the vehicle is greater than the size of the end of the support member 30 facing the inner panel 10 along the width direction of the vehicle.

[0040] For example, refer to Figure 4 In one embodiment of the utility model, a glue groove 31 is provided at one end of the support member 30 facing the outer panel 20, and the adhesive is filled in the glue groove 31. In order to facilitate the application of adhesive, a glue groove 31 is provided at the end of the support member 30 facing the outer panel 20, and the adhesive is filled in the glue groove 31, which can prevent the adhesive from overflowing. Specifically, the extension direction of the glue groove 31 is the same as the extension direction of the end of the support member 30, so that the amount of adhesive applied can be guaranteed, and the support member 30 and the outer panel 20 can be better bonded. In one embodiment, the glue groove 31 can extend along the width direction of the vehicle. As an optional method, the notch of the glue groove 31 changes in a decreasing state in the direction close to the bottom of the groove, which can facilitate the filling of the adhesive, and can also reduce the amount of adhesive used on the basis of ensuring the contact area between the adhesive and the outer panel 20, thereby reducing costs. As an optional method, a plurality of adhesive grooves 31 can be provided at intervals along the width direction of the vehicle, and the adhesive overflowing from each adhesive groove 31 can flow between two adjacent adhesive grooves 31, further improving the bonding reliability between the support member 30 and the outer panel 20, and reducing the use of adhesive to a certain extent. Figure 3 and Figure 4 A reinforcing rib 33 may be provided between two adjacent adhesive grooves 31 to further improve the structural strength of the support member 30 .

[0041] For example, refer to Figure 5 In one embodiment of the utility model, the automobile tailgate further includes a reinforcing sheet metal 40, which is provided on the inner panel 10, and the supporting member 30 connects the reinforcing sheet metal 40 and the outer panel 20. In actual application, other components are usually installed and arranged on the inner panel 10. For this reason, the reinforcing sheet metal 40 is provided on the inner panel 10, which can provide an installation position for other components, and the reinforcing sheet metal 40 increases the structural strength of the inner panel 10 at this position, which can provide a better fixing effect for other components and improve the stability of the installation and fixing of other components. As an optional method, the reinforcing sheet metal 40 and the inner panel 10 are integrally formed, which can reduce the use of connecting components and improve the structural strength.

[0042] Exemplarily, in one embodiment of the present invention, the support member 30 is detachably connected to the reinforcing sheet metal 40. Specifically, since the inner panel 10 has a good structural strength at the location where the reinforcing sheet metal 40 is provided, in this embodiment, one end of the support member 30 facing the inner panel 10 is connected to the reinforcing sheet metal 40, so that the end of the support member 30 facing the inner panel 10 can be reliably connected. In one embodiment, the support member 30 is snap-fitted to the reinforcing sheet metal 40.

[0043] For example, in one embodiment of the utility model, an adhesive is applied at the connection between the support member 30 and the reinforcing sheet metal 40. In this embodiment, the applied adhesive can cooperate with other connection structures to effectively improve the connection reliability between the support member 30 and the reinforcing sheet metal 40. It can be understood that the support member 30 is connected to the reinforcing sheet metal 40 by snapping and is also fixed by adhesive.

[0044] For example, in one embodiment of the utility model, the tailgate of the automobile further includes a back door lock, and the back door lock is connected to the reinforced sheet metal 40. By providing the back door lock, the tailgate of the automobile can be opened and closed. Moreover, the back door lock is connected to the reinforced sheet metal 40, which can ensure the strength of the back door lock installation position.

[0045] To achieve the above purpose, the embodiment of the utility model provides a vehicle, including the above-described automobile tailgate. Specifically, the specific structure of the automobile tailgate refers to the above embodiment. Since the vehicle adopts all the technical solutions of the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, which will not be described one by one here.

[0046] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the embodiment of the present invention. All equivalent structural changes made by using the description and drawings of the embodiment of the present invention under the inventive concept of the embodiment of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the embodiment of the present invention.
