[0048] The embodiment of the utility model provides a hood connection device, which includes a first connection structure, a retractable structure and a second connection structure. One of the first connection structure and the second connection structure is fixedly connected to the vehicle body, and the other is fixedly connected to the hood. The retractable structure is rotatably connected to the first connection structure, and the retractable structure is rotatably connected to the second connection structure when it is in an extended state, and is fixedly connected to the second connection structure when it is in a retracted state, so that the hood can be flipped and retracted relative to the vehicle body, so as to drive the hood to flip and retract relative to the vehicle body. After the hood is installed, it is prevented from blocking the installation of parts at other stations, so as to facilitate the installation of parts or the filling of washing liquid on the hood and the front windshield.

[0049] In order to make the above-mentioned purposes, features and advantages of the embodiments of the utility model more obvious and easy to understand, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0050] See also Figures 1 to 4 The embodiment of the utility model provides a hood connection device, which includes a first connection structure 10, a retractable structure and a second connection structure 40. One of the first connection structure 10 and the second connection structure 40 is configured to be fixedly connected to the vehicle body, and the other is configured to be fixedly connected to the hood. The vehicle body has a front windshield, which is usually glass, and the front windshield is adjacent to the hood. The retractable structure is connected between the first connection structure 10 and the second connection structure 40 to drive the hood to flip and retract relative to the vehicle body. In this way, after the hood is installed, the hood is prevented from blocking the installation of parts in other stations, for example, the hood is prevented from blocking the installation of parts between it and the front windshield.

[0051] like Figures 1 to 4As shown, the first connection structure 10 is fixedly connected to the vehicle body, and correspondingly, the second connection structure 40 is fixedly connected to the hood. The first connection structure 10 includes a first connection plate 11, a second connection plate 12, and a fourth limit plate 15. The first connection plate 11 and the second connection plate 12 are connected at their ends, that is, one end of the first connection plate 11 is connected to one end of the second connection plate 12. The first connection plate 11 and the second connection plate 12 can be an integral structure, the normal line of the first connection plate 11 and the normal line of the second connection plate 12 are parallel, and the first connection plate 11 and the second connection plate 12 can be V-shaped.

[0052] The surface of the first connecting plate 11 is configured to be attached to and fixedly connected to the vehicle body. Exemplarily, a first mounting hole 13 is provided on the surface of the first connecting plate 11, and the first mounting hole 13 passes through the first connecting plate 11, and the first mounting hole 13 can be interference-fitted with the first mounting column on the hood. Alternatively, a first threaded hole is correspondingly provided on the vehicle body, and a first screw is passed through the first mounting hole 13 and connected to the first threaded hole, thereby fixing the first connecting plate 11 relative to the vehicle body.

[0053] The second connecting plate 12 is rotatably connected to the telescopic structure. For example, the second connecting plate 12 is hingedly connected to the telescopic structure (referred to as hinged). A first reinforcing rib 14 is also provided on the surface of the second connecting plate 12 facing the telescopic structure. The extension direction of the first reinforcing rib 14 can be consistent with the extension direction of the second connecting plate 12.

[0054] The side of the second connecting plate 12 adjacent to the first connecting plate 11 is provided with a fourth limiting plate 15, that is, the fourth limiting plate 15 is provided on the side of the second connecting plate 12 and adjacent to the first connecting plate 11. Exemplarily, the angle between the axis of the first connecting plate 11 and the axis of the second connecting plate 12 is less than 90°. The two opposite side surfaces of the first connecting member are respectively connected to the two opposite side surfaces of the second connecting member, and one side surface of the first connecting member and one side surface of the correspondingly connected second connecting member are located on the inner side of the other side surface of the first connecting member and the other side surface of the correspondingly connected second connecting member. The fourth limiting plate 15 is correspondingly provided on the inner side surface of the first connecting member.

[0055] The fourth limiting plate 15 protrudes from the surface of the second connecting plate 12 facing the telescopic structure. The fourth limiting plate 15 serves as a baffle of the telescopic structure and is used to limit the rotation angle of the telescopic structure relative to the second connecting plate 12. When the telescopic structure rotates to contact the fourth limiting plate 15, it cannot continue to rotate. This position is an extreme position of the telescopic structure rotating relative to the first connecting structure 10, which is the extreme position of the telescopic structure rotating clockwise relative to the first connecting structure 10.

[0056] In some possible examples, the first connection structure 10 further includes a fifth limiting plate 16, which is disposed on a side of the second connection plate 12 adjacent to the first connection plate 11 and located on a side of the fourth limiting plate 15 away from the first connection plate 11. In contrast, the telescopic structure has a sixth limiting plate 26, which protrudes from a surface of the second connection plate 12 away from the telescopic structure.

[0057] The sixth limiter and the fifth limiter are used to limit the rotation angle of the telescopic structure relative to the second connecting plate 12. When the sixth limiter plate 26 of the telescopic structure rotates to contact the fifth limiter plate 16, it cannot continue to rotate. This position is another limit position of the telescopic structure relative to the first connecting structure 10, which is the limit position of the telescopic structure rotating counterclockwise relative to the first connecting structure 10.

[0058] See also Figures 1 to 4 The retractable structure is rotatably connected to the first connection structure 10, and the retractable structure is rotatably connected to the second connection structure 40 when in the extended state, and is fixedly connected to the second connection structure 40 when in the retracted state, so that the hood can be flipped and retracted relative to the vehicle body. After the hood is installed, the retractable structure is in the extended state so that the hood avoids other workstations, so that the parts of the rear workstation can be installed. After the parts are installed, the retractable structure is in the retracted state to meet the hood opening and closing operations.

[0059] In some possible exemplary embodiments, the telescopic structure includes a first middle piece 20, a second middle piece 30 and a fixing piece. One end of the first middle piece 20 is rotatably connected to the first connecting structure 10, the other end of the first middle piece 20 is rotatably connected to one end of the second middle piece 30, and the other end of the second middle piece 30 is rotatably connected to the second connecting structure 40.

[0060] The first middle piece 20 is rotatable relative to the first connection structure 10 (e.g., the second connection plate 12), for example, the first middle piece 20 is hinged to the first connection structure 10. The second middle piece 30 is rotatable relative to the first middle piece 20, for example, the first middle piece 20 is hinged to the second middle piece 30, and the second connection structure 40 is rotatable relative to the second middle piece 30. For example, the second middle piece 30 is hinged to the second connection structure 40. When the first middle piece 20, the second middle piece 30, and the second connection structure 40 are relatively rotated, the telescopic structure is in an extended state, and the first middle piece 20 and the second middle piece 30 enable the second connection structure 40 to rotate and telescope relative to the first connection structure 10, which can drive the hood to flip and telescope relative to the vehicle body, that is, the hood can move forward and backward relative to the vehicle body and rotate relative to the vehicle body.

[0061] In some possible implementations, a first hinge hole 17 is provided at one end of the first connection structure 10 (e.g., the second connection plate 12), and the first hinge hole 17 passes through the first connection structure 10. A second hinge hole and a third hinge hole 25 are provided at both ends of the first middle member 20, respectively, and both the second hinge hole and the third hinge hole 25 pass through the first middle member 20. A fourth hinge hole and a fifth hinge hole 32 are provided at both ends of the second middle member 30, respectively, and both the fourth hinge hole and the fifth hinge hole 32 pass through the second middle member 30. A sixth hinge hole is provided at one end of the second connection structure 40, and the sixth hinge hole passes through the second connection structure 40.

[0062] The first hinge shaft 71, the second hinge shaft 72 and the third hinge shaft 73 all include a main body and a limiter connected to one end of the main body. The main body of the first hinge shaft 71 is inserted into the first hinge hole 17 and has an interference fit with the second hinge hole. The limiter of the first hinge shaft 71 is located on the side of the first connection structure 10 away from the telescopic structure. The main body of the second hinge shaft 72 is inserted into the third hinge hole 25 and has an interference fit with the fourth hinge hole. The limiter of the second hinge shaft 72 is located on the side of the first middle piece 20 away from the second middle piece 30. The main body of the third hinge shaft 73 is inserted into the fifth hinge hole 32 and has an interference fit with the sixth hinge hole. The limiter of the third hinge shaft 73 is located on the side of the second middle piece 30 away from the second connection structure 40.

[0063] The first middle piece 20, the second middle piece 30 and the second connecting structure 40 can also be relatively fixed, such as Figure 4 As shown, when the first middle piece 20, the second middle piece 30 and the second connecting structure 40 are relatively fixed, the retractable structure is in a retracted state, and the first middle piece 20 and the second middle piece 30 enable the second connecting structure 40 to rotate relative to the first connecting structure 10, and the length of the rotating arm is fixed, which can drive the hood to flip relative to the vehicle body.

[0064] Specifically, the fixing member is connected to the first middle member 20, the second middle member 30 and the second connecting structure 40, and the telescopic structure is in a retracted state. The second middle member 30 is rotated to overlap with a portion of the first middle member 20, and a portion of the second connecting structure 40 overlaps with the second middle member 30. At this time, the first middle member 20, the second middle member 30 and the second connecting structure 40 are relatively fixed by the fixing member, the second middle member 30 is retracted relative to the first middle member 20, and the telescopic structure is in a retracted state.

[0065] The fixing member is separated from the first middle member 20, the second middle member 30 and the second connecting structure 40, the telescopic structure is in an extended state, the second middle member 30 is rotatable relative to the first middle member 20, and the second connecting structure 40 is rotatable relative to the second middle member 30. That is, after the fixing member is disassembled, the second middle member 30 can be unfolded relative to the first middle member 20, and the telescopic structure is in an extended state.

[0066] For some possible implementations, see Figure 3 , the first middle piece 20, the second middle piece 30 and the second connecting structure 40 are correspondingly provided with fixing holes 24, and the fixing parts include corresponding bolts 50 and nuts 60. When the telescopic structure is in a contracted state, the fixing holes 24 of the first middle piece 20, the second middle piece 30 and the second connecting structure 40 are opposite, and the bolts 50 are penetrated in the fixing holes 24 and connected with the nuts 60. Such a configuration is convenient for installation and disassembly, and it is not easy to damage the first middle piece 20, the second middle piece 30 and the second connecting structure 40. The bolts 50 and the nuts 60 can be installed and disassembled manually or automatically. Exemplarily, the bolts 50 and the nuts 60 are automatically disassembled by using pneumatic chucks, motors and other devices after the telescopic structure moves to a certain position.

[0067] The diameter of one of the fixing hole 24 of the first middle piece 20 and the fixing hole 24 of the second connection structure 40 is smaller than the diameter of the fixing hole 24 of the second middle piece 30, and the diameter of the other is greater than or equal to the diameter of the fixing hole 24 of the second middle piece 30. The bolt 50 includes a head 51 and a rod 52 connected to each other, and the rod 52 includes a large diameter section 53 and a small diameter section 54, and the large diameter section 53 is located between the small diameter section 54 and the head 51. The head 51 abuts against one of the first middle piece 20 and the second connection structure 40, and the end surface of the large diameter section 53 connected to the small diameter section 54 abuts against the other of the first middle piece 20 and the second connection structure 40, and the small diameter section 54 protrudes outward and is connected to the bolt 50. In this way, when the first middle piece 20, the second middle piece 30 and the second connection structure 40 are fixed, the first middle piece 20, the second middle piece 30 and the second connection structure 40 are pressed against each other.

[0068] Exemplarily, the aperture of the fixing hole 24 of the second connection structure 40 is smaller than the aperture of the fixing hole 24 of the second middle piece 30, and the aperture of the fixing hole 24 of the first middle piece 20 is greater than or equal to the aperture of the fixing hole 24 of the second middle piece 30. The head 51 of the bolt 50 abuts against the first middle piece 20, and the large diameter section 53 of the bolt 50 is passed through the fixing hole 24 of the first middle piece 20 and the fixing hole 24 of the second middle piece 30, and abuts against the second connection structure 40. The small diameter section 54 of the bolt 50 is passed through the fixing hole 24 of the second connection structure 40 and connected to the bolt 50.

[0069] Continue reading Figures 1 to 4The first middle member 20 includes a first segment 21 and a second segment 22 connected at the ends, the second segment 22 is connected to the second middle member 30, and is opposite to the second middle member 30 when the telescopic structure is in the contracted state. One end of the first segment 21 is connected to one end of the second segment 22, the other end of the first segment 21 is connected to the first connecting structure 10, and the other end of the second segment 22 is connected to the second middle member 30. The second segment 22 is provided with a fixing hole 24. When the telescopic structure is in the contracted state, the second segment 22 is opposite to the second middle member 30, for example, overlapped.

[0070] The first segment 21 and the second segment 22 may be an integral structure, and the normal line of the first segment 21 is parallel to the normal line of the second segment 22. The extension direction of the first segment 21 intersects with the extension direction of the second segment 22, so that the first segment 21 and the second segment 22 are V-shaped or U-shaped.

[0071] In this configuration, the second segment 22 is connected to the second middle piece 30, the first segment 21 is staggered with the second middle piece 30, and the second segment 22 is provided with a fixing hole 24 for fixedly connecting with the second middle piece 30 and the second connecting structure 40, having sufficient installation space and preventing the bolt 50 from contacting the first connecting structure 10.

[0072] In some possible examples, a second reinforcing rib 23 is further provided on the surface of the first segment 21 away from the first connection structure 10, and the extension direction of the second reinforcing rib 23 may be consistent with the extension direction of the first segment 21 to increase the strength of the first segment 21. The second reinforcing rib 23 may also extend to the second segment 22 to increase the strength of the connection between the first segment 21 and the second segment 22.

[0073] In order to facilitate the installation of the fixing member, in some possible examples, a first limiting plate 27 is provided on the side of the first segment 21 adjacent to the second segment 22, and the first limiting plate 27 protrudes from the surface of the second segment 22 away from the first connecting structure 10. When the telescopic structure is in a contracted state, the second middle piece 30 abuts against the first limiting plate 27, and at this time, the fixing hole 24 of the second middle piece 30 is opposite to the fixing hole 24 of the second segment 22, which facilitates the connection of the fixing member. At the same time, when the second middle piece 30 turns to contact with the first limiting plate 27, it cannot continue to rotate. The first limiting plate 27 can also limit the movement of the second middle piece 30, which is the extreme position of the counterclockwise rotation of the second middle piece 30 relative to the first middle piece 20.

[0074] The second segment 22 is further provided with a third limiting plate 28, which is adjacent to one end of the second segment 22 away from the first segment 21 and protrudes from the surface of the second segment 22 away from the first connecting structure 10, and is used to limit the rotation angle of the second middle piece 30 relative to the second segment 22. When the second middle piece 30 rotates to contact the third limiting plate 28, it cannot continue to rotate. The third limiting plate 28 limits the movement of the second middle piece 30, which is the extreme position of the clockwise rotation of the second middle piece 30 relative to the first middle piece 20.

[0075] In order to further facilitate the installation of the fixing part, a second limiting plate 31 is correspondingly provided on the side of the second middle part 30, and the second limiting plate 31 protrudes from the surface of the second middle part 30 away from the first middle part 20. For example, the second limiting plate 31 is opposite to the first limiting plate 27. When the telescopic structure is in the contracted state, the second connecting structure 40 is against the second limiting plate 31, and at this time, the fixing hole 24 of the second middle part 30 is opposite to the fixing hole 24 of the second connecting structure 40, which is convenient for the connection of the fixing part. At the same time, when the second connecting structure 40 contacts the second limiting plate 31, it cannot continue to rotate. The second limiting plate 31 can also limit the movement of the second connecting structure 40, which is the extreme position of the counterclockwise rotation of the second connecting structure 40 relative to the second middle part 30.

[0076] Continue reading Figures 1 to 4 The second connection structure 40 includes a third segment 41 and a fourth segment 42 connected at the ends. The third segment 41 is connected to the second middle piece 30 and is opposite to the second middle piece 30 when the telescopic structure is in the contracted state. One end of the third segment 41 is connected to one end of the fourth segment 42, the other end of the third segment 41 is connected to the second middle piece 30, and the other end of the fourth segment 42 is connected to the first connection structure 10. The third segment 41 is provided with a fixing hole 24. When the telescopic structure is in the contracted state, the third segment 41 is opposite to the second middle piece 30, for example, overlapped.

[0077] The fourth segment 42 is folded relative to the third segment 41 so that the normal of the fourth segment 42 intersects the normal of the third segment 41, and the fourth segment 42 and the third segment 41 are an integral structure. In this way, the hood and the body are not on the same plane, and the fourth segment 42 is folded relative to the third segment 41 to achieve the connection between the hood connection device and the hood and the body.

[0078] The surface of the fourth segment 42 is configured to be attached to and fixedly connected with the hood. Exemplarily, the surface of the fourth segment 42 is provided with a second mounting hole 43, which passes through the fourth segment 42, and the second mounting hole 43 can be interference-fitted with the second mounting column on the hood. Alternatively, the vehicle body is correspondingly provided with a second threaded hole, and the first screw is passed through the second mounting hole 43 and connected with the second threaded hole, thereby fixing the second connection structure 40 relative to the vehicle body.
