[0011] Wherein, the two mounting ears are respectively fixedly connected to the first mounting member by bolts.

[0012] It is further defined that in the above-mentioned bent arm hinge structure, the fixing seat further comprises a limiting rod fixedly arranged between two inner side walls of the seat body;

[0013] Wherein, the limiting rod can abut against the bending arm rotating member to limit the rotation angle of the bending arm rotating member relative to the fixing seat.

[0014] It is further defined that, in the above-mentioned bent arm hinge structure, arc transition portions are respectively provided between the first rotating portion and the second rotating portion, between the second rotating portion and the third rotating portion, and between the third rotating portion and the fourth rotating portion.

[0015] It is further defined that, in the above-mentioned bent arm hinge structure, reinforcing ribs are fixedly provided on the first rotating part, the second rotating part, the third rotating part and the fourth rotating part.

[0016] It is further defined that in the above-mentioned bent arm hinge structure, the first rotating part is provided with a rotating pin hinged to the two inner side walls of the seat body;

[0017] The rotating pin includes an insertion column which passes through the seat body and the first rotating part and is loosely matched with the seat body and the first rotating part, and a limit head fixedly arranged at one end of the insertion column, the limit head abuts against the outer wall of the seat body at a corresponding position, and a pin is inserted at the end of the insertion column away from the limit head and is located on the side of the seat body away from the limit head.

[0018] It is further defined that in the above-mentioned bent arm hinge structure, a gasket is sleeved on the rotating pin, and the gasket is clamped between the bent arm rotating member and the inner side wall of the seat body.

[0019] The present application also provides a vehicle door system, which comprises a vehicle frame, a side panel fixedly arranged on the vehicle frame, and a door rotatably arranged on the side panel through any of the above-mentioned curved arm hinge structures:

[0020] Wherein, the fixing seat is fixedly arranged on the end face of the frame away from the hatch, and the bent arm rotating member is fixedly connected to the end face of the hatch close to the frame.

[0021] It is further defined that the above-mentioned vehicle door system further includes at least one connecting assembly fixedly disposed between the side panel and the vehicle frame;

[0026] 2. In a door system adopting the above-mentioned bent arm hinge structure, the hatch door is opened and closed by the relative rotation of the bent arm rotating member and the fixed seat. Since the fixed seat is arranged on the end face of the frame away from the hatch door, the bent arm rotating member is always located on the inner side of the hatch door during the opening and closing process of the hatch door, thereby ensuring the integrity of the hinge structure and the vehicle body. At the same time, the bent arm rotating member avoids interference with the position of the side enclosure member through the internal clearance during the rotation process, thereby greatly improving the rotation angle of the bent arm rotating member relative to the fixed seat, that is, increasing the maximum opening and closing angle of the hatch door while satisfying the matching clearance of the door system.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0036] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0037] The curved arm hinge structure and the door system provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0038] like Figures 1 to 4 As shown, an embodiment of the present application provides a vehicle door system, including a vehicle frame 400 , a side enclosure member 300 fixedly disposed on the vehicle frame 400 , and a hatch 100 rotatably disposed on the side enclosure member 300 via a bent arm hinge structure 600 .

[0039] In a preferred embodiment, Figures 1 to 4 As shown, a sealing strip 200 capable of abutting against the cabin door 100 is fixedly provided on the side surrounding member 300 at a position corresponding to the edge of the cabin door 100 .

[0040] It can be understood that when the hatch 100 is in a closed state, the sealing strip 200 can improve the sealing between the vehicle body parts. On the other hand, the sealing strip 200 can buffer the closing force of the hatch 100, thereby reducing the impact force and impact noise when the hatch 100 is closed, thereby improving the service life and working reliability of the hatch 100.

[0041] In a preferred embodiment, Figures 1 to 4 As shown, at least one connecting assembly 500 is fixedly disposed between the side enclosure member 300 and the vehicle frame 400 .

[0042] The connection assembly 500 is located inside the vehicle body and is used for fixed connection between the side enclosure member 300 and the vehicle frame 400 .

[0043] In a preferred embodiment, Figures 1 to 4 As shown, the connection assembly 500 includes a transition plate 520 fixedly arranged on the end surface of the frame 400 close to the cabin door 100, and a connecting piece 510 fixedly connected to the end surface of the side enclosure member 300 close to the frame 400 is fixedly arranged on the transition plate 520.

[0044] The connecting member 510 has a cavity therein, and the frame 400 and the transition plate 520 are provided with a travel groove communicating with the cavity.

[0045] In an embodiment of the present application, the above-mentioned vehicle door system is adopted, and the travel groove and the cavity can provide a rotation space for the bent arm hinge structure 600 when the cabin door 100 is opened and closed. At the same time, the bent arm hinge structure 600 can be shielded by the connecting piece 510, thereby improving the integrity of the vehicle door system.

[0046] like Figures 1 to 6 As shown, an embodiment of the present application provides a bent arm hinge structure 600 , including a fixing seat 610 fixedly disposed on an end surface of a vehicle frame 400 away from a cabin door 100 , and a bent arm rotating member 620 hingedly disposed on the fixing seat 610 .

[0047] The bent arm rotating member 620 passes through the travel groove and the cavity and is fixedly connected to the end surface of the hatch 100 close to the frame 400.

[0048] In an embodiment of the present application, the above-mentioned bent arm hinge structure is adopted, and the opening and closing of the hatch 100 is achieved by the relative rotation of the bent arm rotating member 620 and the fixed seat 610. During the opening and closing process of the hatch 100, the bent arm rotating member 620 is always located on the inner side of the hatch 100, thereby ensuring the integrity of the hinge structure and the vehicle body.

[0049] In a preferred embodiment, Figures 1 to 6As shown, the fixed seat 610 includes a seat body 611 in a “U” shape and fixedly connected to the frame 400 , and the bent arm rotating member 620 is located in the seat body 611 and hinged to the two inner side walls of the seat body 611 .

[0050] In a preferred embodiment, Figures 1 to 6 As shown, the fixing seat 610 further includes mounting ears 612 symmetrically and fixedly disposed on two outer side walls of the seat body 611 , and the two mounting ears 612 are respectively fixedly connected to the vehicle frame 400 with bolts.

[0051] It is understandable that the fixed connection form between the bent arm hinge structure 600 and the frame 400 is not limited to the above-mentioned one. For example, other fixing structures such as welding and clamping can also be used, as long as the fixed connection between the two can be achieved. It will not be elaborated here.

[0052] In a preferred embodiment, Figures 1 to 6 As shown, the fixing seat 610 further includes a limiting rod 613 fixedly disposed between two inner side walls of the seat body 611 .

[0053] When the hatch 100 is in an open state, the limiting rod 613 can abut against the bent arm rotating member 620 to limit the rotation angle of the bent arm rotating member 620 relative to the fixing seat 610 .

[0054] In a preferred embodiment, Figures 4 to 6 As shown, the bent arm rotating part 620 is in the shape of a non-closed loop, and includes a first rotating part 621 hinged to the fixing seat 610, a second rotating part 623 fixedly connected to the first rotating part 621 and perpendicular to each other, a third rotating part 624 fixedly connected to the second rotating part 623 and perpendicular to each other, a fourth rotating part 625 fixedly connected to the third rotating part 624 and perpendicular to each other, and a fixing part 626 fixedly connected to the fourth rotating part 625 and used for connecting to the cabin door 100.

[0055] The length of the third rotating portion 624 is greater than the length of the first rotating portion 621 .

[0056] In an embodiment of the present application, the above-mentioned bent arm hinge structure is adopted. When the bent arm rotating member 620 rotates relative to the fixed seat 610, since the bent arm rotating member 620 is generally in a non-closed loop shape, the bent arm rotating member 620 has a larger internal clearance space during the rotation process, thereby avoiding interference with the position of the side enclosure member 300 or the sealing strip 200, and thus being able to increase the rotation angle of the bent arm rotating member 620 relative to the fixed seat 610 to a greater extent, that is, to increase the maximum opening and closing angle of the hatch 100 while satisfying the fitting clearance of the vehicle door system.

[0057] In a preferred embodiment, Figures 4 to 6As shown, arc transition portions are respectively provided between the first rotating portion 621 and the second rotating portion 623 , between the second rotating portion 623 and the third rotating portion 624 , and between the third rotating portion 624 and the fourth rotating portion 625 .

[0058] In an embodiment of the present application, the above-mentioned bent arm hinge structure is adopted, and the rotation angle of the bent arm rotating part 620 relative to the fixed seat 610 can be further matched through the arc transition part. When the cabin door 100 is opened and closed, the arc transition part can further increase the internal clearance space of the bent arm rotating part 620, thereby providing a larger opening and closing angle of the cabin door 100 while ensuring a smaller fitting clearance of the hinge structure.

[0059] In a preferred embodiment, Figures 4 to 6 As shown, reinforcing ribs 627 are fixedly provided on the first rotating portion 621 , the second rotating portion 623 , the third rotating portion 624 , and the fourth rotating portion 625 .

[0060] It is understandable that the reinforcing ribs 627 can be provided on the inner wall surface or the outer wall surface of the first rotating portion 621 , the second rotating portion 623 , the third rotating portion 624 , and the fourth rotating portion 625 , so as to improve the overall structural strength of the bent arm rotating member 620 .

[0061] Preferably, when the reinforcing ribs 627 are arranged on the inner wall surfaces of the first rotating portion 621 , the second rotating portion 623 , the third rotating portion 624 , and the fourth rotating portion 625 , interference between the reinforcing ribs 627 and the fixing base 610 can be avoided, thereby facilitating miniaturization of the fixing base 610 .

[0062] In a preferred embodiment, Figures 4 to 6 As shown, a rotation pin 622 hinged to two inner side walls of the seat body 611 is provided on the first rotation portion 621 .

[0063] In a preferred embodiment, Figures 4 to 6 As shown, the rotating pin 622 includes an insertion column that penetrates the seat body 611 and the first rotating portion 621 and is loosely matched with the seat body 611 and the first rotating portion 621, and a limiting head fixedly arranged at one end of the insertion column.

[0064] The limiting head abuts against the outer wall of the seat body 611 at the corresponding position, and a pin located on the side of the seat body 611 away from the limiting head is inserted at the end of the plug post away from the limiting head.

[0065] It can be understood that the positioning between the fixing seat 610 and the bending arm rotating member 620 is achieved through the cooperation between the limiting head and the latch, and the rotation cooperation between the fixing seat 610 and the bending arm rotating member 620 is achieved at the same time.

[0066] In a preferred embodiment, Figures 4 to 6As shown, two washers 630 are sleeved on the rotating pin 622 , and the two washers 630 are respectively sandwiched between the bent arm rotating member 620 and the two inner side walls of the seat body 611 .

[0067] It is understandable that the gasket 630 can reduce the matching clearance between the fixed seat 610 and the bent arm rotating member 620, thereby improving the stability of the bent arm rotating member 620 when rotating relative to the fixed seat 610.

[0068] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0069] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
