Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle body connecting parts, and in particular relates to a combined door hinge and a vehicle. Background Art

[0002] In addition to the conventional side-opening structure, the car door opening methods also have a variety of structural forms such as gull wing, scissors, butterfly door, etc. designed and developed for high-end models. Among them, the butterfly door is connected by two upper and lower hinges. The upper hinge and the lower hinge jointly provide an inclined rotation axis for the door opening, making the butterfly door appear to open diagonally upward.

[0003] The existing butterfly door assembly process requires the lower hinge to be assembled to the door sheet metal assembly first, and then the door assembly is installed as a whole to the body in the welding workshop. In the next step, the door assembly needs to be removed in the final assembly workshop to install accessories such as the door interior panel. Since the lower hinge is usually directly connected to the body end by screwing, the door gap and surface difference between the door assembly and the body need to be re-matched during the removal and reinstallation process, which leads to the problem of difficult door disassembly and assembly and low efficiency; in addition, since the door assembly usually has two configurations, manual and electric, the turning radius required for the door switch is different for different configurations, so the door hinge cannot be universal, and corresponding lower hinges need to be developed for products with different configurations, resulting in high hinge development and production costs. Utility Model Content

[0004] The embodiment of the utility model provides a combined vehicle door hinge, which aims to improve the convenience and efficiency of disassembling and reassembling the vehicle door and save the development and production costs of the vehicle door hinge.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: in the first aspect, a combined door hinge is provided, comprising:

[0006] Body-end hinges and door-end hinges; and

[0007] A hinge arm, one end of which is detachably connected to the door end hinge, and the other end of which is rotatably connected to the vehicle body end hinge;

[0008] Among them, an installation positioning structure is provided between the door end hinge and the hinge arm, and the installation positioning structure is used to limit the connection position of the door end hinge and the hinge arm.

[0009] In combination with the first aspect, in a possible implementation, a positioning hole is provided on the hinge arm, a positioning pin is provided on the door end hinge, and the positioning pin is plugged into and matched with the positioning hole to form an installation positioning structure.

[0013] In one possible implementation, the door end hinge has a first mating surface, and the hinge arm has a second mating surface, and the first mating surface and the second mating surface abut against each other along the axial direction of the locating pin; wherein the first mating surface is provided with a locating pin and a threaded hole threadedly connected to the fastener; and the second mating surface is provided with a locating hole and a through hole suitable for passing the fastener.

[0014] In some embodiments, a hinge seat is provided on the hinge at the vehicle body end, a hinge head is provided at one end of the hinge arm away from the hinge at the vehicle door end, and the hinge head is hinged to the hinge seat via a pin shaft.

[0015] Exemplarily, the hinge seat has two connecting ears spaced apart from each other, the hinge head is located between the two connecting ears, the pin passes through the hinge head and the two connecting ears, and the pin is rotatably matched with the hinge head and / or the two connecting ears.

[0016] For example, a connection hole is provided at one end of the hinge arm close to the door hinge, and the connection hole is used to connect the hinge support rod.

[0017] The beneficial effect of the combined door hinge provided by the utility model is that: compared with the prior art, the combined door hinge of the utility model can use the installation positioning structure to limit the connection position of the door end hinge and the hinge arm, thereby reducing the difficulty of installation alignment when the door is disassembled and reassembled, and improving the door assembly efficiency; on this basis, since the hinge arm can be disassembled from the body end hinge and the door end hinge, when facing doors with different configurations, the hinge arm can be adaptively replaced separately without redeveloping the body end hinge and the door end hinge, thereby reducing the number of mold opening processes for different hinges and reducing the hinge development and production costs.

[0018] In a second aspect, an embodiment of the utility model further provides a vehicle, comprising the above-mentioned combined door hinge.

[0019] Compared with the prior art, the vehicle provided by the utility model adopts the above-mentioned combined door hinge, and can use the installation positioning structure to limit the connection position of the door end hinge and the hinge arm, thereby reducing the difficulty of installation alignment when the door is disassembled and reassembled, and improving the door assembly efficiency; on this basis, since the hinge arm can be disassembled from the body end hinge and the door end hinge, when facing doors with different configurations, the hinge arm can be adaptively replaced separately, without the need to redevelop the body end hinge and the door end hinge, thereby reducing the number of mold opening processes for different hinges and reducing the hinge development and production costs.

DETAILED DESCRIPTION

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on another element or indirectly on another element. It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "back", "top", "bottom", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0026] Please also read Figures 1 to 3 The combined door hinge provided by the utility model is now described. The combined door hinge comprises a vehicle body end hinge 10, a vehicle door end hinge 20, and a hinge arm 30; one end of the hinge arm 30 is detachably connected to the vehicle door end hinge 20, and the other end is rotatably connected to the vehicle body end hinge 10; wherein, an installation positioning structure 300 is provided between the vehicle door end hinge 20 and the hinge arm 30, and the installation positioning structure 300 is used to limit the connection position of the vehicle door end hinge 20 and the hinge arm 30.

[0027] It should be noted that, in this embodiment, the body-end hinge 10 can be screwed, anchored or welded to the body. Similarly, the door-end hinge 20 can also be screwed, anchored or welded to the door. Considering the convenience of replacement in case of damage, it is preferred to adopt a connection method in which the body-end hinge 10 is screwed and fixed to the body, and the door-end hinge 20 is screwed and fixed to the door.

[0028] In this embodiment, the detachable connection method between the hinge arm 30 and the door end hinge 20 can be screwed or anchored, as long as the two can be detachable and the structures of the two are not damaged during the detachment. Specifically, screwing can be preferably used. The hinge arm 30 and the body end hinge 10 can be rotatably connected by a pin shaft 40, or a hinged method can be directly used to ensure that the hinge arm 30 can swing relative to the body end hinge 10. Specifically, considering the opening method of the butterfly door, the axial direction of the hinge shaft between the hinge arm 30 and the body end hinge 10 and the structural shape of the hinge arm 30 itself can be adaptively designed based on the door opening angle.

[0029] It should be explained that the installation positioning structure 300 in the present embodiment can specifically be a positioning structure in which the axis / hole on the door end hinge 20 is plugged into the corresponding hole / axis on the hinge arm 30, or it can be a positioning structure in which the groove / convex rib on the door end hinge 20 is correspondingly embedded with the rib / groove on the hinge arm 30. During installation, the installation positioning structure 300 is used to first locate the relative position of the hinge arm 30 and the door end hinge 20, and then the connection and fixation are performed. Since the door gap and the surface difference between the door and the body have been matched during the initial installation, when the door is disassembled, as long as the door end hinge 20 and the door are not disassembled, and the body end hinge 10 and the body are not disassembled, but only the door end hinge 20 and the hinge arm 30 are disassembled, in this case, when reassembling the door, it is only necessary to ensure the connection position accuracy between the door end hinge 20 and the hinge arm 30 to ensure the matching of the door gap and the surface difference between the door and the body, thereby greatly reducing the process difficulty of disassembling and reassembling the door.

[0030] It should be noted that, in the present embodiment, both the rotational connection structure between the hinge arm 30 and the body-end hinge 10 and the connection method between the hinge arm 30 and the door-end hinge 20 can be disassembled, which is equivalent to the combined door hinge provided in the present embodiment being composed of three modular parts. For different door configuration requirements, it is only necessary to remove and replace the corresponding hinge arm 30, and neither the body-end hinge 10 nor the door-end hinge 20 needs to be redeveloped. In other words, it is only necessary to develop one of the modular parts, namely the hinge arm 30, for different configurations. This can reduce the types of modular parts designed and molded for different products, thereby reducing the hinge development and production costs.

[0031] Based on the above, compared with the prior art, the combined door hinge provided in this embodiment can use the installation positioning structure 300 to limit the connection position of the door end hinge 20 and the hinge arm 30, thereby reducing the difficulty of installation alignment when the door is disassembled and reassembled, and improving the door assembly efficiency; on this basis, since the hinge arm 30 and the body end hinge 10 and the door end hinge 20 can be disassembled, when facing doors with different configurations, the hinge arm 30 can be adaptively replaced alone, without the need to redevelop the body end hinge 10 and the door end hinge 20, thereby reducing the number of mold opening processes for different hinges and reducing the hinge development and production costs.

[0032] In some embodiments, see Figure 1 and Figure 2The hinge arm 30 is provided with a positioning hole 301, and the door end hinge 20 is provided with a positioning pin 302, which is plugged into the positioning hole 301 to form an installation positioning structure 300. It is only necessary to ensure the position accuracy of the positioning hole 301 and the positioning pin 302. When assembling, the relative position accuracy between the hinge arm 30 and the door end hinge 20 can be ensured by first plugging the positioning pin 302 into the positioning hole 301, and then fastening the two together. The structure is simple and the assembly is convenient and quick.

[0033] It should be noted that, since hinge processing generally adopts an open mold casting method, the positioning pin 302 in this embodiment can be cast integrally with the door end hinge 20 .

[0034] For some possible implementations, see Figure 2 and Figure 3 The door end hinge 20 has a first limiting surface 21 , and the hinge arm 30 has a second limiting surface 31 . The second limiting surface 31 abuts against the first limiting surface 21 along a first direction; wherein the first direction is perpendicular to the axial direction of the positioning pin 302 .

[0035] Since the positioning solely relies on the locating pin 302 and the locating hole 301, it is impossible to limit the relative rotational freedom between the locating pin 302 and the locating hole 301, which may cause deviation in the assembly angle between the hinge arm 30 and the door end hinge 20. Therefore, the first limiting surface 21 and the second limiting surface 31 are abutted and limited along the first direction perpendicular to the axial direction of the locating pin 302, so as to limit the assembly angle between the hinge arm 30 and the door end hinge 20 and improve the accuracy of disassembly and reassembly of the door; in addition, the abutment between the first limiting surface 21 and the second limiting surface 31 can also form a supporting effect on the hinge arm 30, thereby sharing the bearing capacity of the locating pin 302 and the connection position, and improving the connection strength and stability of the door.

[0036] On the basis of the above, combined with Figure 2 and Figure 3 The door end hinge 20 has a third limiting surface 22, and the hinge arm 30 has a fourth limiting surface 32, and the fourth limiting surface 32 abuts against the third limiting surface 22 along a second direction; wherein the second direction intersects with the first direction, and the second direction is perpendicular to the axial direction of the positioning pin 302.

[0037] On the one hand, the abutment between the third limiting surface 22 and the fourth limiting surface 32 can further improve the relative position accuracy between the hinge arm 30 and the door end hinge 20. On the other hand, it can cooperate with the abutment relationship between the first limiting surface 21 and the second limiting surface 31 to achieve large-angle support for the hinge arm 30, thereby improving the connection strength between the hinge arm 30 and the door end hinge 20, avoiding excessive stress on the positioning pin 302 and the connection position of the butterfly door model during the tilting and switching process, and improving the door switching stability.

[0038] Alternatively, see Figure 1 and Figure 2 In this embodiment, a fastener 33 is provided on the hinge arm 30 along the axial direction of the positioning pin 302, and the fastener 33 is screwed and fixed to the door end hinge 20. The fastener 33 may be a bolt, and the fastener 33 can be fixed along the axial direction of the positioning pin 302 by screwing and fixing along the axial direction of the positioning pin 302, thereby cooperating with the positioning pin 302 to constrain the hinge arm 30 along the radial direction of the positioning pin 302, thereby realizing a reliable connection between the hinge arm 30 and the door end hinge 20, and the assembly and disassembly are simple and convenient.

[0039] It should be noted that see Figure 2 and Figure 3 The above-mentioned door end hinge 20 has a first mating surface 23, and the hinge arm 30 has a second mating surface 34. The first mating surface 23 and the second mating surface 34 abut against each other along the axial direction of the positioning pin 302; wherein, the first mating surface 23 is provided with a positioning pin 302 and a threaded hole 231 threadedly connected to the fastener 33; the second mating surface 34 is provided with a positioning hole 301 and a through hole 341 suitable for passing the fastener 33.

[0040] The first mating surface 23 and the second mating surface 34 can increase the contact area between the hinge arm 30 and the door end hinge 20, thereby improving the connection reliability and the door switch stability. The fastener 33, such as a bolt, passes through the through hole 341 and is directly screwed and fastened to the threaded hole 231 without the need for additional nuts, thereby facilitating disassembly and assembly.

[0041] In order to prevent the operating end of the fastener 33 , such as a bolt, from protruding too high from the surface of the hinge arm 30 , the through hole 341 in this embodiment is preferably in the form of a stepped hole so that the operating end of the fastener 33 can be at least partially sunk into the large diameter end of the through hole 341 .

[0042] As a specific connection method of the vehicle body end hinge 10 and the hinge arm 30, please refer to Figure 1 and Figure 2The hinge seat 11 is provided on the vehicle body end hinge 10, and a hinge head 35 is provided at one end of the hinge arm 30 away from the vehicle door end hinge 20, and the hinge head 35 is hinged to the hinge seat 11 through a pin 40. The hinge seat 11 and the vehicle body end hinge 10 can be integrally cast, a first axial hole is provided on the hinge seat 11, and a second axial hole is provided on the hinge head 35. After the first axial hole and the second axial hole are aligned, a pin 40 is passed through to connect them. The hinge arm 30 and the vehicle body end hinge 10 can be disassembled by pulling out the pin 40, so that the hinge arm 30 can be easily replaced to meet different door configuration requirements.

[0043] Specifically, the hinge seat 11 has two mutually spaced connecting ears 111, the hinge head 35 is located between the two connecting ears 111, the pin 40 passes through the hinge head 35 and the two connecting ears 111, and the pin 40 is rotatably matched with the hinge head 35 and / or the two connecting ears 111. The hinge head 35 is inserted between the two connecting ears 111, and the two connecting ears 111 can be used to form a two-way limit for the hinge head 35 along the axial direction of the pin 40, thereby preventing the hinge head 35 from moving along the axial direction of the pin 40, which is conducive to improving the stability of the door switch.

[0044] It should be noted that see Figure 1 The hinge arm 30 has a connection hole 36 at one end close to the door hinge 20, and the connection hole 36 is used to connect the hinge support rod. Since the door needs to be supported by a hinge support rod such as a hydraulic telescopic rod when it is opened, and the hinge support rod needs to be connected to the vehicle body, in this case, the connection hole 36 for connecting the hinge support rod is set on the hinge arm 30, which can not only provide sufficient support force close to the door, but also only needs to disassemble the connection between the hinge arm 30 and the door hinge 20 when disassembling the door, without disassembling the hinge support rod, so as to facilitate the disassembly and reassembly of the door.

[0045] It is important to understand that, see Figure 2 In this embodiment, a plurality of mounting holes 12 are provided on the vehicle body end hinge 10 and the vehicle door end hinge 20. The vehicle body end hinge 10 is screwed and fixed to the vehicle body by passing bolts through the mounting holes 12 provided thereon, and the vehicle door end hinge 20 is screwed and fixed to the vehicle door by passing bolts through the mounting holes 12 provided thereon, which not only ensures the fixing reliability of the vehicle body end hinge 10 and the vehicle door end hinge 20, but also facilitates the disassembly and replacement of the vehicle body end hinge 10 and the vehicle door end hinge 20, thereby reducing the difficulty and cost of maintenance.

[0046] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, comprising the above-mentioned combined door hinge.

[0047] Compared with the prior art, the vehicle provided by the utility model adopts the above-mentioned combined door hinge, and can use the installation positioning structure 300 to limit the connection position of the door end hinge 20 and the hinge arm 30, thereby reducing the difficulty of installation alignment when the door is disassembled and reassembled, and improving the door assembly efficiency; on this basis, since the hinge arm 30 can be disassembled from the body end hinge 10 and the door end hinge 20, when facing doors with different configurations, the hinge arm 30 can be adaptively replaced separately, without the need to redevelop the body end hinge 10 and the door end hinge 20, thereby reducing the number of mold opening processes for different hinges and reducing the hinge development and production costs.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
