Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile parts, in particular to a hinge device and an automobile. BACKGROUND

[0002] With the development of automobile technology, the engine compartment structure of the automobile has more free space after continuous innovation, so the engine compartment of the automobile is often designed to have a storage room. In related technology, the automobile hinge is usually provided with a support piece for auxiliary support, which is connected to the front end or middle end of the vehicle body corresponding to the front cover of the automobile. Therefore, after the front cover of the automobile is opened, the support piece will block the side of the front engine compartment, which is not conducive to the user to take and place the items in the storage room from the side. SUMMARY

[0003] The purpose of the present application is to solve the problem that the support piece connected to the conventional automobile hinge in related technology blocks the side of the engine compartment, which is not convenient for the user to take and place the items in the engine compartment from the side of the engine compartment. The present application provides a hinge device and an automobile. Through the improvement of the overall structure, the support piece is formed into a hidden connection structure, which can greatly reduce or even eliminate the influence of the support piece on the side of the engine compartment.

[0033] With the popularity of electric vehicles, compared with traditional fuel vehicles, the cabin of electric vehicles has more free space, so the front cabin of electric vehicles begins to appear the design of storage room. In the related art, the hinge system of the automobile front cover is arranged with support pieces on both sides of the cabin as the power mechanism for opening the automobile front cover. The support pieces are connected to the front end or the middle end of the automobile front cover corresponding to the vehicle body, so that the support pieces will block the side of the cabin after the automobile front cover is opened. Since the cabin has the function of storage, the design of the support pieces is very unfavorable for users to flexibly take and place the items in the storage room from the side of the cabin. Moreover, the opening frequency of the automobile front cover will also greatly increase with the design of the storage space. In the related art, the structure design of the automobile hinge is limited by the previous use environment, and the structural strength is low, which cannot provide sufficient protection for the frequent opening and closing of the automobile front cover, thereby being difficult to meet the storage requirements of the front cabin of electric vehicles. Especially for large SUVs (suburban utility vehicles), the size of the automobile front cover is larger, and if it needs to be frequently opened and closed, higher strength requirements are put forward for the hinge device of the automobile front cover. In order to facilitate users to take and place the items from the side of the cabin, and at the same time, to provide higher strength support for the frequently opened automobile front cover, the application provides a hinge device and an automobile.

[0034] The application will be described below in conjunction with the drawings and specific embodiments:

[0035] The hinge device 100 provided by the application can provide higher strength support for the frequently opened automobile front cover, as shown in Figure 1 and Figure 2 A hinge device 100 provided by the application, comprising: a movable arm 110, comprising a fixed segment 111 and a connecting segment 112, the fixed segment 111 is used for fixedly connecting a cover 300; a fixed arm 120, comprising a first side plate 121, a second side plate 122 and a cover plate 123, the first side plate 121 and the second side plate 122 are oppositely arranged, the cover plate 123 is fixedly connected between the first side plate 121 and the second side plate 122, the connecting segment 112 is rotationally connected to the first side plate 121 and the second side plate 122, and the first side plate 121 and the second side plate 122 are both used for fixedly connecting with a vehicle body 200; a support piece 130, at least one of the fixed segment 111 and the connecting segment 112 is universally connected with one end of the support piece 130, and the other end of the support piece 130 is universally connected to the vehicle body 200 close to the fixed arm 120.

[0036] The support piece 130 is fixed at one end of the vehicle body 200, and is arranged close to the fixed section 111, so that the support piece 130 supports the hinge joint between the vehicle cover 300 and the vehicle body 200 after the vehicle cover 300 is opened, forming a hidden structure design, and the structure of the hinge device 100 is relatively concentrated, so that the space in the engine compartment is more simple, and a larger storage space can be designed. When the hood needs to be installed between the left and right sides of the vehicle cover 300 and the vehicle body 200, the hidden structure of the support piece 130 will not divide the hood, and the hood can be installed on both sides of the vehicle cover 300.

[0037] Since the support piece 130 is designed as a hidden structure, the support moment of the support piece 130 is short, and the support force of the support piece 130 is large, so that the fixed arm 120 having a connection relationship will generate a large force, and the hidden structure improvement accordingly improves the requirement for the structural strength of the fixed arm 120;

[0038] Further, the structure of the fixed arm 120 is designed to meet the application of the hidden structure, the first side plate 121 and the second side plate 122 are relatively arranged and can be fixedly connected with the vehicle body 200, and the first side plate 121 and the second side plate 122 are formed into an integrated structure by the cover plate 123, thereby effectively improving the stability of the connection between the fixed arm 120 and the vehicle body 200, and enhancing the structural strength of the fixed arm 120; in combination with the connection section 112, the first side plate 121 and the second side plate 122 are rotatably connected, that is, the first side plate 121 and the second side plate 122 can simultaneously support the movable arm 110, compared with the rotatable connection between the movable arm 110 and the single plate structure in the related art, the structure design of the fixed arm 120 has two fixed surfaces and two support points, which can effectively improve the support of the fixed arm 120 to the movable arm 110, not only meeting the structural strength requirement of the hidden structure design, but also providing sufficient support and stability for the vehicle cover 300.

[0039] The hinge device 100 of the present application has a hidden structure design of the support piece 130, so that the user can take and place the objects in the engine compartment from the side of the engine compartment, and the overall structural strength is effectively improved by the design of the fixed arm 120, meeting the strength requirement of the hidden structure, and also providing sufficient support and stability for the automobile front cover, further meeting the requirement of frequent opening and closing of the automobile front cover, and being especially suitable for supporting the automobile front cover with large size.

[0040] As Figures 3-5As shown, in some optional embodiments, the first side plate 121 comprises a first mounting section 1211, a bending section 1212 and a second mounting section 1213 connected in sequence, the first mounting section 1211 is connected with the cover plate 123 at an end away from the bending section 1212, the connecting section 112 is rotationally connected to the first mounting section 1211, and the second mounting section 1213 is connected with the vehicle body 200. The distance between the first mounting section 1211 and the second side plate 122 is less than the distance between the second mounting section 1213 and the second side plate 122.

[0041] The first side plate 121 and the second side plate 122 both need to be fixedly connected with the vehicle body 200, which can be bolted with the vehicle body mounting plate 210 extending out of the vehicle body 200. Through the design of the bending section 1212, the distance between the second mounting section 1213 and the second side plate 122 can be effectively increased. When the connecting section 112 is rotationally connected between the first mounting section 1211 and the second side plate 122, there will be excess space between the connecting section 112 and the second mounting section 1213 to form a mounting space, which can further enable the vehicle body mounting plate 210 extending out of the vehicle body 200 to be arranged in the mounting space and fixedly connected with the second mounting section 1213. If the vehicle body mounting plate 210 extends horizontally from the vehicle body 200, the mounting space formed can be further used to perform flanging treatment on the vehicle body mounting plate 210 when the first side plate 121 is fixed vertically, i.e., the vehicle body mounting plate 210 can have a vertical flange structure to be fixedly connected with the second mounting section 1213. Therefore, the mounting space formed is beneficial to improving the stress form of the vehicle body mounting plate 210, which can effectively improve the stability and connection strength of the connection between the first side plate 121 and the vehicle body 200, and compared with the installation and fixation of the vehicle body mounting plate 210 on the side of the second mounting section 1213 away from the connecting section 112, it is also convenient for the vehicle body mounting plate 210 to continue extending to the second side plate 122 after being fixedly connected with the second mounting section 1213, and then being fixedly connected with the second side plate 122, so as to simplify the structure of the vehicle body mounting plate 210 and optimize the overall installation structure of the vehicle body 200.

[0042] In some optional embodiments, the bending section 1212 is bent away from the second side plate 122. The bending section 1212 is bent in a direction away from the second side plate 122, which can directly increase the installation space of the second mounting section 1213. The structure of the bending section 1212 is simple, and the entire fixing arm 120 can be formed by one-time stamping.

[0043] In some optional embodiments, the second side plate 122 is provided with a second mounting hole 1221, and the second mounting hole 1221 is arranged in a staggered manner with the first side plate 121. The second mounting hole 1221 is convenient for connecting and fixing by selecting a bolt. The side of the first side plate 121 away from the second side plate 122 is selected as the operation surface for installation. The second mounting hole 1221 on the second side plate 122 is arranged in a staggered manner with the first side plate 121, that is, when the operation surface for installation is selected for operation, the second mounting hole 1221 is not blocked by the first side plate 121, thereby facilitating the bolt fixing of the second mounting hole 1221 from the operation surface for installation, and the installation operation of the hinge can be completed outside the vehicle body 200.

[0044] In some optional embodiments, the first side plate 121 is provided with a first mounting hole 1214, and the first mounting hole 1214 and the second mounting hole 1221 are both rectangular through holes adapted to the space position adjustment of the hood 300. The first side plate 121 can also be fixedly connected with the vehicle body 200 by a bolt. The connection of the first side plate 121 and the second side plate 122 can both be fixed with the vehicle body 200 by a bolt. The bolt fixing of the first mounting hole 1214 and the second mounting hole 1221 can determine the relative position of the hood 300 and the vehicle body 200. The first mounting hole 1214 and the second mounting hole 1221 are further designed as rectangular through holes. In order to adapt to the space position adjustment of the hood 300, the bolt used for fixing can have a moving adjustment space in the rectangular through hole. If the installation direction of the hinge is Y direction, that is, the length direction of the bolt connecting and fixing the arm 120 and the vehicle body 200 is Y direction, the design of the rectangular through hole is not only convenient for the X direction and Z direction adjustment of the hinge, but also convenient for sequentially determining the adjustment values of the X direction and the Z direction. For example, according to the working condition, the X direction and the Z direction need to be adjusted by one unit of moving distance. The rectangular through hole can be adaptively designed as a square, and the screw rod can move by one unit in the X direction and the Z direction. When moving one unit in the X direction, the screw rod is located at one corner of the rectangular through hole. Then, when moving one unit in the Z direction, the screw rod is located at another corner of the rectangular through hole. Therefore, through the design of the rectangular shape, it is very convenient to observe and confirm the adjustment progress and adjustment amount during the adjustment process. If the X direction needs to be adjusted by one unit of moving distance and the Z direction needs to be adjusted by two units of moving distance according to the working condition, the rectangular through hole is adaptively designed as a rectangle. The installation position of the arm 120 in the X, Y and Z directions is directly the space position adjustment of the hood 300 relative to the vehicle body 200. After adjustment to the appropriate position, the nut is tightened for fixation.

[0045] In some optional embodiments, the cover plate 123 is provided with a limiting portion 1231 arranged towards the connecting segment 112, and the limiting portion 1231 is used to abut against the connecting segment 112. The limiting portion 1231 is designed on the cover plate 123 and belongs to the extension of the cover plate 123, so as to facilitate the stamping forming of the designed cover plate 123. The limiting portion 1231 extends towards the connecting segment 112, and the extension angle and extension length of the limiting portion 1231 can be adjusted according to specific working conditions, as long as the rotating angle range of the movable arm 110 can be controlled. When the connecting segment 112 rotates to abut against the limiting portion 1231, it is the maximum angle of the movable arm 110. The limiting portion 1231 as the over-opening limiting portion of the vehicle cover 300 can prevent the opening angle of the vehicle cover 300 from exceeding the set range.

[0046] In some optional embodiments, when the vehicle cover 300 is opened, the support 130 is arranged to be inclined towards the front end of the vehicle cover 300. That is, compared with the connecting position of the support 130 and the vehicle body 200, the connecting position of the support 130 and the movable arm 110 is farther away from the fixed arm 120. By restricting the connecting position of the support 130 and the vehicle body 200, the shielding effect of the support 130 on the side of the engine compartment can be effectively reduced, so as to realize the auxiliary supporting function at the hinge of the vehicle cover 300 and ensure the convenience effect of the hidden structure of the support 130 for the user to take and place the objects in the engine compartment.

[0047] In some optional embodiments, the connecting segment 112 is an arc-shaped segment curved away from the vehicle cover 300. The connecting segment 112 is used to transmit the force for bearing the vehicle cover 300. After the automobile hinge is installed, the arc-shaped structure designed to be curved towards the front engine compartment of the automobile not only can optimize the structure stress of the connecting segment 112 and improve the bearing capacity of the movable arm 110, but also can effectively increase the rotating angle range of the connecting segment 112, that is, compared with the straight line structure, the arc-shaped connecting segment 112 can be rotated to a larger angle between the first side plate 121 and the second side plate 122.

[0048] In some optional embodiments, the connecting segment 112 is provided with a weight-reducing groove 1121. The connecting segment 112 needs a certain thickness to form a rotating connection, but the corresponding structural strength of the corresponding thickness of the plate material is not needed, so the weight-reducing groove 1121 is designed to remove the excess structural strength, which can effectively reduce the weight of the connecting segment 112, thereby optimizing the overall structure. The weight-reducing groove 1121 can be designed as a long strip-shaped through hole along the length direction of the connecting segment 112, or the connecting segment 112 can be formed as a cavity structure.

[0049] In some optional embodiments, the support 130 is connected with the fixed segment 111; since the support 130 is designed as a hidden structure, the support force provided will be larger, the force borne by the connected movable arm 110 will also be larger, and thus the strength requirement of the connection between the movable arm 110 and the support 130 is improved. Since the fixed segment 111 of the movable arm 110 is fixedly connected with the cover 300, the fixed segment 111 also has a certain structural strength requirement. Connecting the support 130 to the fixed segment 111 facilitates the overall design to strengthen the structural strength of the fixed segment 111, such as thickening the plate, etc. Compared with connecting the support 130 to the connecting segment 112, not only can the torque of the support 130 be fully optimized, but also the overall design for production is facilitated.

[0050] In some optional embodiments, the fixed segment 111 and the connecting segment 112 are integrally formed; since the fixed segment 111 of the movable arm 110 needs to have sufficient structural strength, and the connecting segment 112 needs to have a certain thickness to realize the rotary connection, the design of integrally forming the fixed segment 111 and the connecting segment 112 not only facilitates production and manufacturing without the need for welding assembly, but also can obtain better structural strength, for example, the movable arm 110 is designed as a cast structure, which can be directly formed by casting process.

[0051] In some optional embodiments, the fixed arm 120 is a punched plate; the structural design of the first side plate 121, the second side plate 122 and the cover plate 123 can be punched and formed once by cutting the plate, which is easy to mass-produce and can effectively control the production cost.

[0052] Based on the same inventive concept, the embodiments of the present application also provide an automobile, which comprises a vehicle body 200 and a cover 300, and the hinge device 100 as in Embodiment 1 is used to connect the vehicle body 200 and the cover 300. The vehicle body 200 is fixedly connected with the first side plate 121 and the second side plate 122, the cover 300 is fixedly connected with the fixed segment 111, and the support 130 is connected with the vehicle body 200 near the fixed arm 120.

[0053] Based on the convenience of production and processing and the needs of specific working conditions, certain combinations are made in various optional embodiments, such as shown in Figure 1 and Figure 2 , specifically, the movable arm 110 is designed as a cast structure, and the structure of the fixed arm 120 can be punched and formed once, which is convenient for mass production;

[0054] The movable arm 110 is a rod member divided into a fixed segment 111 and a connecting segment 112 in front and back, the fixed segment 111 is a thickened inverted L-shaped steel plate, two bolt through holes are formed on the top surface of the fixed segment 111, which facilitates the fixed connection with the hood 300 by bolts, a ball head mounting hole is formed on the side surface of the fixed segment 111, which facilitates the ball head connection with the support member 130, the connecting segment 112 is an arc-shaped segment curved away from the hood 300, and is a hollow strip structure member, along the length direction of the connecting segment 112, a lightening groove 1121 hole is formed on the arc-shaped connecting segment 112, a pin hole is formed at the end of the connecting segment 112, which can be connected with the fixed arm 120 by a pin shaft.

[0055] As shown in Figures 3-5 The fixed arm 120 is a nearly U-shaped plate member composed of a first side plate 121, a second side plate 122 and a cover plate 123, the cover plate 123 is vertically connected with the first side plate 121 and the second side plate 122 on both sides, the cover plate 123 is located at the top of the first side plate 121 and the second side plate 122, a square second mounting hole 1221 is formed on the bottom of the second side plate 122, and the second mounting hole 1221 is arranged in a staggered manner with the first side plate 121, that is, when the side of the first side plate 121 away from the second side plate 122 is taken as a reference surface, the first side plate 121 will not block the second mounting hole 1221, the through hole size of the first mounting hole 1214 and the second mounting hole 1221 is larger than the diameter of the mounting bolt, which facilitates the spatial adjustment of the installation position of the fixed arm 120.

[0056] The first side plate 121 can be sequentially divided into a first mounting section 1211, a bending section 1212 and a second mounting section 1213 from top to bottom, the second mounting section 1213 is provided with a square first mounting hole 1214, and the bending section 1212 is bent away from the second side plate 122, thereby increasing the distance between the second mounting section 1213 and the second side plate 122. The first mounting section 1211 and the second side plate 122 are provided with relatively arranged pin holes for mounting the connecting section 112, that is, the connecting section 112 is hinged between the first side plate 121 and the second side plate 122, and is close to the cover plate 123. The distance between the first side plate 121 and the first mounting section 1211 is slightly larger than the size of the connecting section 112, so as to facilitate the control of the articulated movable arm 110 not to shake when rotating. When the connecting section 112 rotates in the U-shaped space of the fixed arm 120, the second mounting section 1213 and the connecting section 112 have a certain distance as the mounting space of the vehicle body mounting plate 210. The cover plate 123 is also provided with a limiting portion 1231, which is a part extending downward from the body of the cover plate 123. The plate-shaped limiting portion 1231 is directly formed during stamping, and the limiting portion 1231 extends obliquely towards the connecting section 112, so that the limiting portion 1231 can abut against the connecting section 112 when the connecting section 112 rotates upward to a certain angle, thereby limiting the connecting section 112 from continuing to rotate upward and controlling the rotation angle range of the connecting section 112.

[0057] The support member 130 is a rod structure, and can also be a telescopic rod structure according to actual working conditions. The top end of the support member 130 is connected to the fixed section 111 through a ball head structure to form a universal connection, and the bottom end is connected to the vehicle body 200 through a ball head structure to form a universal connection.
