[0051] Embodiment one

[0052] The embodiment relates to a luggage cover mounting hinge, and provides a hinge structure facilitating face difference adjustment of a luggage cover 1.

[0053] Since the trunk lid 1 needs to be hingedly installed on the vehicle body through the hinge arm 3, the hinge arm 3 has a long size and a curved "goose neck" section, the precision size of the hinge arm 3 is difficult to control, and the surface difference of the trunk lid 1 after installation is often out of control index requirements due to the deviation of the precision of the hinge arm 3 itself. The existing hinge structure of the trunk lid 1 is difficult to adjust the surface difference of the trunk lid 1, and the connecting pin shaft 5 on the hinge mounting seat 4 of the trunk lid needs to be removed, which is time-consuming and laborious. At the same time, the hinge precision is poor, the unqualified rate of the surface difference is high, which leads to low automobile assembly quality and increases the overall assembly cost.

[0054] Moreover, in the existing hinge structure of the trunk lid 1, the space condition at the pin shaft 5 is poor, there is no adjustment space, and the position of the pin shaft 5 is not easy to adjust, which further increases the difficulty of adjusting the surface difference of the trunk lid 1.

[0055] By analyzing the above problems in the existing structure, it can be found that the adjustment space at the pivot of the existing trunk lid mounting hinge is small, which is not conducive to the overall disassembly adjustment mode. At the same time, the arm body 30 of the hinge arm 3 has a very long "goose neck" curved section. Once the manufacturing and processing precision of the hinge arm 3 deviates slightly, it will affect the surface difference matching problem between the trunk lid 1 and the vehicle body surface. Once the surface difference problem of the trunk lid 1 occurs, it will inevitably lead to an increase in automobile defective products.

[0056] The trunk lid mounting hinge of the embodiment is designed to overcome the deficiencies in the prior art. The overall structure is shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 .

[0057] Specifically, the trunk lid mounting hinge includes a hinge arm 3 for mounting the trunk lid 1, a hinge mounting seat 4 for connecting the vehicle body, and a pin shaft 5 and an adjusting member 6 provided on the hinge mounting seat 4. The hinge arm 3 is hingedly connected to the hinge mounting seat 4 through the pin shaft 5, and the position of the pin shaft 5 on the hinge mounting seat 4 is adjustable. At the same time, the adjusting member 6 is in transmission connection with the pin shaft 5, and the adjusting member 6 can be operated to shift. The shifted adjusting member 6 drives the pin shaft 5 to change position to adjust the position of the pin shaft 5 on the hinge mounting seat 4.

[0058] It should be noted that based on the overall design idea described above, the technical scheme of the utility model can adopt various different specific implementation structures, forms or configuration sequences. For example, the adjusting member 6 described above can adopt a swing lever, a cam or other structural mode, abut against the pin shaft 5, and drive the pin shaft 5 to shift by rotating or swinging the adjusting member 6; of course, the screw rod form described below in the embodiment can also be screwed onto the hinge mounting seat 4. The specific setting sequence, assembly mode and the like of the luggage cover 1, the vehicle body sheet metal 2, the hinge rotary arm 3 and the hinge mounting seat 4 and the like can also be flexibly adjusted. For the parts required for the overall scheme implementation but not involved in the overall setting described above, reasonable and flexible design can be made by referring to the mature setting means in the field, the actual situation during implementation and the like. The specific implementation scheme described below in the embodiment is only one of the relatively optimal schemes formed by various combinations and changes thereof, and in actual implementation, the person skilled in the art can make flexible adjustment and improvement in combination with the actual situation. Obviously, the various specific form combinations and changes thereof can form many schemes, and the specific implementation scheme of the embodiment is within the protection scope of the utility model.

[0059] In the embodiment, as shown in Figure 5 , Figure 6 In order to set the pin shaft 5 on the hinge mounting seat 4, the hinge mounting seat 4 is provided with a pin shaft hole 402 for penetrating the pin shaft 5, and the pin shaft hole 402 is configured as an elongated hole to allow the height position of the pin shaft 5 on the hinge mounting seat 4 to be adjustable. The pin shaft hole 402 is formed in the elongated shape on the hinge mounting seat 4, and the pin shaft 5 penetrating the pin shaft hole 402 can be adjusted in the length direction of the elongated hole, thereby providing an adjustable position structure of the pin shaft 5 which is convenient for processing and technical implementation. According to the swing opening and closing action of the luggage cover 1 on the vehicle body, the pin shaft 5 is arranged horizontally in the left-right direction of the vehicle, and the height adjustment strategy of the pin shaft 5 is more effective for the face difference control of the luggage cover 1; therefore, the height adjustable form of the pin shaft 5 on the hinge mounting seat 4 is more beneficial to meet the requirements of the face difference adjustment control of the luggage cover 1. In specific implementation, the length direction of the pin shaft hole 402 which is the elongated hole can be consistent with the height direction of the vehicle, thereby achieving the purpose of adjusting the height position of the pin shaft 5.

[0060] As mentioned above, preferably, the adjusting member 6 of the present embodiment adopts a screw rod structure, and is screwed on the hinge mounting base 4, and the adjusting member 6 is supported below the pin shaft 5; when the adjusting member 6 is rotated, the height position of the adjusting member 6 on the hinge mounting base 4 can be changed, thereby driving the position adjustment of the pin shaft 5. The adjusting member 6 is screwed on the hinge mounting base 4, and the position movement of the adjusting member 6 can be realized by rotating operation, and then the supporting effect of the adjusting member 6 on the pin shaft 5 is utilized, so that when the adjusting member 6 is adjusted to be higher, the pin shaft 5 is driven to be higher, and when the adjusting member 6 is adjusted to be lower, the pin shaft 5 is driven to be lower by the gravity of the hinge rotary arm 3 and the luggage cover 1, thereby providing an adjusting structure which is simple and effective, easy to process and construct, and easy to implement.

[0061] Specifically, the adjusting member 6 of the present embodiment includes a screw rod 60 for screwing the hinge mounting base 4, and a screw head 61 for rotating operation. The screw head 61 is arranged on the top of the screw rod 60, and a butt protrusion 610 is formed on the top of the screw head 61, which is connected to the pin shaft 5 in abutment. The screw head 61 is arranged on the top of the screw rod 60, which is convenient for rotating operation of the adjusting member 6 by using a wrench or other common tools; the butt protrusion 610 is arranged on the top of the screw head 61, which is abutted with the pin shaft 5, thereby obviously improving the driving stability between the adjusting member 6 and the pin shaft 5.

[0062] Of course, a threaded hole can be directly machined on the hinge mounting base 4, and the screw rod 60 described above is screwed in the threaded hole. Preferably, as shown in Figure 7 and in combination with Figure 8 to Figure 10 , the hinge mounting base 4 of the present embodiment is fixed with a projection nut 62, and the screw rod 60 of the adjusting member 6 is screwed and connected with the projection nut 62.

[0063] The projection nut 62 is additionally arranged on the hinge mounting base 4, and the screw connection between the projection nut 62 and the adjusting member 6 can greatly improve the screwing firmness of the adjusting member 6 on the hinge mounting base 4, and prevent the screwing hole from being directly machined on the plate body of the hinge mounting base 4, which is easy to cause the screwing hole to slip. In view of the above setting requirement of the adjusting member 6, the existing mounting bolt can be used as the adjusting member 6, of course, the adjusting member 6 can also be separately machined to provide an adjusting member 6 with more suitable size specifications; the projection nut 62 can be a nut accessory with matching thread specifications, which is convenient to purchase and equip, and can reduce the overall cost of the luggage cover mounting hinge.

[0064] Of course, there are many different structure schemes for the specific setting structure of the hinge mounting base 4. In the present embodiment, as shown in Figure 6 and in combination with Figure 10As shown, the hinge mounting base 4 comprises a support plate 400 in the shape of a "door" in cross section, and mounting base plates 401 connected to the bottom of the two side plates of the support plate 400 respectively. Among them, the pin shaft holes 402 are two respectively provided on the two side plates, and the hinge joint part of the hinge rotating arm 3 is located between the two side plates. The mounting base plates 401 are connected to the vehicle body through the mounting base connectors 7.

[0065] The support plate 400 of the hinge mounting base 4 adopts a "door" shape structure, which can form two opposite side plates. The pin shaft holes 402 are respectively provided on the two side plates, and the pin shaft 5 can be firmly and fixedly installed on the hinge mounting base 4. The hinge joint part of the hinge rotating arm 3 can also be arranged between the two side plates, and the hinge joint part of the hinge rotating arm 3 is provided with a hinge joint hole for the pin shaft 5 to pass through. The mounting base plates 401 provided at the bottom of the support plate 400 provide a suitable connection basis for the installation of the hinge mounting base 4 on the vehicle body panel 2. In specific implementation, an installation window can be provided on the vehicle body panel 2, the hinge mounting base 4 is installed through the installation window from the lower side of the vehicle body panel 2, the mounting base plates 401 are attached to the bottom of the vehicle body panel 2, and the support plate 400 is installed through the installation window to the upper side of the vehicle body panel 2. The mounting base plates 401 can be fixed to the vehicle body panel 2 through a plurality of mounting base connectors 7, and the mounting base connectors 7 can be a ready-made bolt pair. Preferably, two mounting base connectors 7 are installed on each of the two mounting base plates 401 on the two sides to ensure the firmness of the installation of the hinge mounting base 4 on the vehicle body panel 2.

[0066] Based on the above arrangement, the pin shaft 5 of the embodiment comprises a shaft body 500 installed in the two pin shaft holes 402, and an end plate 501 provided at one end of the shaft body 500. Moreover, two limiting platforms 404 are provided on at least one of the side plates, and the two limiting platforms 404 are located on the side of the side plate facing away from the hinge rotating arm 3, and the two limiting platforms 404 are clamped on both sides of the end plate 501, thereby limiting the rotation of the pin shaft 5. Of course, the limiting platforms 404 should be arranged on the same side of the support plate 400 as the adjusting member 6, and the locking nut 505 is arranged on the other side of the support plate 400, and the positions of the two groups of components can be interchanged.

[0067] Two limiting blocks 404 are arranged on the side plates of the support plate 400 at intervals. Since the two limiting blocks 404 are arranged on the left and right sides of the pin shaft hole 402, a guiding channel extending upward and downward is formed between the two limiting blocks 404, and the end plate 501 of the pin shaft 5 can be guided to move upward and downward between the two limiting blocks 404, thereby ensuring the stability of the adjustment direction of the position of the pin shaft 5. At the same time, since the end plate 501 is limited between the two limiting blocks 404, the pin shaft 5 is prevented from rotating relative to the hinge mounting seat 4. When the adjusting member 6 pushes the pin shaft 5, the pin shaft 5 is prevented from rotating due to the stress point of the pin shaft 5 being not in place, and the stability of the transmission of the driving force between the adjusting member 6 and the pin shaft 5 is ensured.

[0068] Based on the arrangement of the end plate 501, a protruding adjusting tongue 502 can be arranged on the end plate 501, which is in abutting cooperation with the adjusting member 6. As shown in Figure 10 , the screw head 61 at the top of the screw rod 60 abuts on the adjusting tongue 502. The protruding adjusting tongue 502 arranged on the end plate 501 is used to receive the driving force of the adjusting member 6, which provides a more stable stress point for the driving between the adjusting member 6 and the pin shaft 5, and is beneficial to further improve the driving effect between the adjusting member 6 and the pin shaft 5. In addition, in order to avoid interference between the hinge rotating arm 3 located between the two side plates of the support plate 400 and the top plate body of the support plate 400 during rotation, an avoiding window 403 can be arranged on the top of the support plate 400 to avoid the hinge joint position of the hinge rotating arm 3.

[0069] For the pin shaft 5, the simplest configuration can of course be adopted, which only includes the above-mentioned shaft body 500 and end plate 501. The shaft body 500 is used to hinge the hinge rotating arm 3 to the hinge mounting seat 4, and the end plate 501 is blocked by the adjusting member 6, so that the pin shaft 5 will not come out of the pin shaft hole 402. However, preferably, as shown in Figure 6 and in combination with Figure 10 , the pin shaft 5 of the embodiment further includes a sleeve 503 sleeved on the shaft body 500, and the two ends of the sleeve 503 are respectively inserted into the two pin shaft holes 402. Moreover, a locking nut 505 can be screwed on the end of the shaft body 500 away from the end plate 501. When the pin shaft 5 is adjusted to a suitable position, the locking nut 505 can be tightened, thereby more stably locking the pin shaft 5 on the hinge mounting seat 4.

[0070] A sleeve 503 is arranged on the shaft body 500 of the pin shaft 5, and the two ends of the sleeve 503 are reliably fitted into the two pin shaft holes 402, so as to effectively improve the fitting reliability of the pin shaft 5 in the pin shaft hole 402. Meanwhile, a bushing 504 can be arranged outside the sleeve 503, so that the bushing 504 plays a good cushioning role between the sleeve 503 and the hinge hole of the hinge swing arm 3, thereby improving the stability of the hinge swing arm 3 when swinging on the hinge mounting seat 4. Of course, the bushing 504 can be integrally injection molded by using plastic, rubber and the like; for example, PVC plastic, thermoplastic elastomer TPE (synthetic rubber) and the like.

[0071] For the specific setting form of the hinge swing arm 3 and the configuration of the related accessories, the existing hinge swing arm 3 structure setting can be referred to. In the embodiment, the hinge swing arm 3 includes a curved arm body 30, one end of the arm body 30 is hinged to the hinge mounting seat 4, and the other end is used to fix the luggage cover 1. The luggage cover 1 of the embodiment is installed on the arm body 30 through two tail door connecting pieces 32. The tail door connecting piece 32 is similar to the above-mentioned mounting seat connecting piece 7, and can also be replaced by an existing bolt pair. Near the hinge mounting seat 4, a drive shaft support 310 is fixed on the arm body 30, and a drive shaft 31 is arranged on the drive shaft support 310. The drive shaft 31 is driven by an external driving mechanism, so as to rotate the entire hinge swing arm 3 around the pin shaft 5, and then realize the opening and closing function of the luggage cover 1.

[0072] In summary, the luggage cover mounting hinge of the embodiment is characterized in that the pin shaft 5 is arranged on the hinge mounting seat 4 in a position-adjustable manner, and the adjusting piece 6 that can be operated is arranged on the hinge mounting seat 4. When the adjusting piece 6 is operated to be displaced, the pin shaft 5 is driven by the transmission between the adjusting piece 6 and the pin shaft 5 to be adjusted in position on the hinge mounting seat 4, so as to improve the operation convenience and stability of the position adjustment of the pin shaft 5. By adjusting the position of the pin shaft 5, the hinge position of the hinge swing arm 3 on the hinge mounting seat 4 can be changed, and then the position adjustment of the luggage cover 1 is realized, so that the surface difference between the luggage cover 1 and the tail surface of the vehicle body reaches the quality control requirement, thereby providing a hinge structure which is convenient for adjusting the surface difference of the luggage cover 1.

[0073] Embodiment Two

[0074] The embodiment relates to an automobile provided with the luggage cover mounting hinge provided in the embodiment one.

[0075] By setting the adjusting member 6 in the luggage cover installation hinge with pin shaft 5 transmission cooperation, with the convenient operation of adjusting member 6, the height position of pin shaft 5 on the hinge mounting seat 4 can be adjusted, and the position adjustment of the luggage cover 1 is realized, so that the surface difference of the luggage cover 1 is quickly and stably adjusted, thereby ensuring that the surface difference of the luggage cover 1 meets the requirements of quality control standards and reducing the unqualified rate of products.

[0076] Moreover, by adding sleeve 503, bushing 504 and other components on the shaft body 500 of pin shaft 5, stable friction fit between the hinge arm 3 and the pin shaft 5 can be achieved during the rotation of the hinge arm 3, which can effectively reduce the noise generated by relative rotation.
