[0002] The vehicle hood is assembled to the vehicle body through the hood hinge. The hood hinge itself only has the function of supporting and rotating the hood and cannot limit the hood. Therefore, the hood needs to be supported by a support rod when it is open. The support rod occupies a large space and has strict layout conditions. In addition, the support rod will block some parts in the cabin, making maintenance operations inconvenient.

[0003] In order to optimize the structure of the hood and prevent the support rod from blocking some components in the cabin, in the prior art, a locking structure is provided on the hood hinge. When the hood is opened, the locking structure can lock the position of the hood hinge to stabilize the hood hinge state and support and limit the hood, thereby omitting the installation of the support rod.

[0004] However, when the hood is open, the locking structure is in a locked state. When closing the hood, a person needs to reach into the hood hinge to unlock the locking structure. Since the hood hinge is set at the rear end edge of the hood and the opening space is small, the hinge structure unlocking method is not convenient to operate. Utility Model Content

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.

[0048] It should be noted that the directions or positional relationships indicated by "front", "rear", "inside", "outside", "up" and "down" in this embodiment are based on the direction of the vehicle itself, where the head of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "up", and the bottom of the vehicle represents "down", the "inside" side refers to the side facing inside the cab, and the "outside" side refers to the side facing outside the cab.

[0049] In addition, the front and rear direction of the vehicle body defined in the embodiments of the present invention refers to the front and rear direction of the forward direction of the vehicle during driving, the left and right direction of the vehicle body defined refers to the left and right direction of the forward direction of the vehicle during driving, and the up and down direction of the vehicle body defined refers to the up and down direction of the forward direction of the vehicle during driving.

[0050] Please also read Figures 1 to 4 , the engine hood hinge provided by the utility model is now described. The engine hood hinge includes a hinge seat 1, a hinge arm 2, a locking structure and an unlocking structure 4. The hinge seat 1 is installed on the vehicle body; the hinge arm 2 is installed on the engine hood 5, and one end is hinged to the hinge seat 1; the hinge arm 2 has an open position and a closed position; the locking structure has a first locking part and a second locking part, the first locking part is arranged on the hinge arm 2, and the second locking part is arranged on the hinge seat 1; the locking structure has a locking state in which the first locking part cooperates with the second locking part, and also has an unlocking state in which the first locking part is separated from the second locking part, and in the locked state, the hinge arm 2 is located in the open position; the unlocking structure 4 is arranged on the engine hood 5; one end of the unlocking structure 4 is connected to the locking structure, and the other end extends to the front edge of the engine hood 5, and the unlocking structure 4 is used to control the locking structure to switch from the locked state to the unlocked state.

[0051] Specifically, the hinge seat 1 is located below the rear edge of the engine hood 5, and the hinge seat 1 is fastened to the vehicle body by bolts. The hinge arm 2 is fixedly connected to the lower surface of the engine hood 5 by bolts. In order to improve the support strength of the hinge arm 2 to the engine hood 5, the hinge arm 2 is a long arm structure. The rear end of the hinge arm 2 and the hinge seat 1 have an overlapped portion, and the hinge point and locking structure of the hinge arm 2 are both located at the overlapped portion.

[0052] The hinge arm 2 can swing around its hinge point; specifically, when the engine hood 5 needs to be opened, a person holds the front edge of the engine hood 5 and lifts the engine hood 5 upward. During the process of lifting the engine hood 5 upward, the hinge arm 2 is driven to swing at the same time, and the first locking portion moves with the hinge arm 2. When the engine hood 5 is opened to a preset angle, that is, when the hinge arm 2 swings to the open position, the first locking portion cooperates with the second locking portion, and the locking structure switches from the unlocked state to the locked state. The locking structure is locked, so that the hinge arm 2 and the hinge seat 1 are relatively fixed, and the hinge arm 2 can support and limit the engine hood 5.

[0053] When the engine hood 5 needs to be closed, the unlocking structure 4 is manually operated to separate the first locking part from the second locking part, and the locking structure is switched from the locked state to the unlocked state. The locking structure no longer locks the hinge arm 2 and the hinge seat 1. Under the action of gravity, the hinge arm 2 and the engine hood 5 swing downward until the engine hood 5 is closed, that is, the hinge arm 2 is in the closed position.

[0054] The engine hood hinge provided by the utility model has a hinge arm 2 for supporting the engine hood 5, and a locking structure for limiting the positional relationship between the hinge arm 2 and the hinge seat 1; when the locking structure is in a locked state, the hinge arm 2 is in an open position, and the locking structure can lock the hinge arm 2 and the hinge seat 1 to stabilize the hinge state of the engine hood, thereby supporting and limiting the engine hood 5. Compared with the prior art, the installation of the support rod structure can be omitted, thereby optimizing the overall structure of the engine hood 5 and the cabin structure; in addition, when the engine hood 5 needs to be closed, the locking structure can be unlocked by manually controlling the other end of the unlocking structure 4. Since the other end of the unlocking structure 4 extends to the front edge of the engine hood 5, there is no need for a person to extend his hand into the rear edge of the engine hood 5 during the unlocking operation, thereby making the unlocking operation convenient.

[0055] In some embodiments, the unlocking structure 4 may be implemented as follows: Figures 4 to 6 The structure shown, see Figures 4 to 6 The unlocking structure 4 includes a steel wire rope 41. The steel wire rope 41 is detachably arranged on the engine hood 5, and the rear end is connected to the locking structure. Preferably, the rear end of the steel wire rope 41 can be fixedly connected to the first locking portion through a fixing block 45.

[0056] By manually pulling the front end of the wire rope 41, the wire rope 41 moves as a whole, and drives the first locking part to move, thereby disengaging the first locking part from the second locking part, and the locking structure is unlocked, and the pulling operation is simple and convenient.

[0057] The steel wire rope 41 is light in weight, occupies little space, is easy to lay, and does not require an avoidance structure on the engine hood 5, thereby simplifying the overall structure of the engine hood 5 and reducing the weight and cost of the entire vehicle. In addition, the steel wire rope 41 can also be completely attached to the lower surface of the engine hood 5 and will not block some components in the cabin, greatly improving the maintainability convenience of the cabin area.

[0058] In addition, in order to facilitate manual application of tension to the steel wire rope 41 , a pull ring 44 is connected to the front end of the steel wire rope 41 .

[0059] See also Figures 1 to 6 On the basis of the above embodiment, the unlocking structure 4 further includes a sheath 42 and a plurality of buckles 43. The sheath 42 is sleeved outside the steel wire 41; the plurality of buckles 43 are sleeved outside the sheath 42 at intervals and are respectively clamped on the engine hood 5.

[0060] The sheath 42 is wrapped around the steel wire 41. Since the steel wire 41 is pulled to move manually, the steel wire 41 cannot be completely fixed relative to the engine hood 5. The sheath 42 is set outside the steel wire 41 to protect the steel wire 41 and prevent the steel wire 41 from rubbing against the engine hood 5. It also supports and fixes the steel wire 41, and the steel wire 41 is attached to the lower surface of the engine hood 5 through a plurality of buckles 43.

[0061] Preferably, the buckle 43 includes a sleeve portion and a clamping portion, the sheath 42 is inserted into the sleeve portion, and the clamping portion is clamped on the engine hood 5 .

[0062] In some embodiments, the locking structure may be configured as follows: Figure 2 and Figure 3 The structure shown, see Figure 2 and Figure 3 The first locking part is an elastic locking member 3, and the second locking part is a limiting hole 11. The elastic locking member 3 is fixedly arranged on the hinge arm 2, and has elastic freedom to extend or retract toward the hinge seat 1; the limiting hole 11 is opened on the hinge seat 1.

[0063] Among them, one end of the unlocking structure 4 is connected to the elastic locking member 3; when in the open position, the elastic locking member 3 is limited in the limiting hole 11, and when in the closed position, the elastic locking member 3 leaves the limiting hole 11, and the end of the elastic locking member 3 elastically abuts against the outer wall of the hinge seat 1.

[0064] The elastic locking piece 3 swings with the hinge arm 2, and the limiting hole 11 is in a fixed state; during the swinging of the hinge arm 2 around the hinge end, the elastic locking piece 3 moves relative to the hinge seat 1, and the elastic locking piece 3 always abuts against the outer wall of the hinge seat 1 during the movement, and is in an energy storage state. When the elastic locking piece 3 moves to the limiting hole 11, the hinge seat 1 no longer limits the elastic locking piece 3, and the elastic locking piece 3 releases its elastic potential energy, thereby being inserted and limited in the limiting hole 11.

[0065] It should be noted that the locking structure is in a locked state only when the elastic locking member 3 is inserted into the limiting hole 11, and once the elastic locking member 3 leaves the limiting hole 11, the locking structure is in an unlocked state, and the elastic locking member 3 stores energy. The elastic locking member 3 leaves the limiting hole 11 by manually pulling the wire rope 41.

[0066] The locking structure adopts an elastic abutment locking method, which is simple to implement in locking and unlocking, and can make the rear end of the hinge arm 2 fit with the hinge seat 1, ensuring the stability of the hinge arm 2 when swinging, and reducing the space occupied by the engine hood hinge.

[0067] In some embodiments, the elastic locking member 3 may be used as follows: Figure 6 The structure shown, see Figure 6 The elastic locking member 3 includes a fixing sleeve 31, a latch 32 and a first elastic member 33. The fixing sleeve 31 is fixedly arranged on the hinge arm 2; the latch 32 is located in the fixing sleeve 31; one end of the latch 32 extends out of the fixing sleeve 31 and passes through the hinge arm 2; the unlocking structure 4 is connected to one end of the latch 32 located in the fixing sleeve 31; the first elastic member 33 is located in the fixing sleeve 31 and sleeved outside the latch 32; one end of the first elastic member 33 is connected to the latch 32, and the other end is connected to the fixing sleeve 31.

[0068] Preferably, the outer periphery of the fixing sleeve 31 is provided with a connecting ear extending outward, and the connecting ear is fixed to the hinge arm 2 by bolts. The inner cavity of the fixing sleeve 31 is a stepped cavity with a cavity diameter decreasing successively. In other words, the inner cavity of the fixing sleeve 31 at least includes a first cavity and a second cavity connected successively, and the inner diameter of the first cavity is defined to be larger than the inner diameter of the second cavity.

[0069] The latch 32 is slidably disposed in the first cavity and the second cavity, and one end of the latch 32 extends out of the first cavity. A ring platform is provided on the outer circumference of the latch 32, and the ring platform is located in the first cavity, and the outer diameter of the ring platform is greater than the inner diameter of the second cavity, that is, the ring platform is limited in the first cavity.

[0070] The first elastic member 33 is located in the first cavity, and two ends of the first elastic member 33 are respectively in contact with the end surface of the ring platform and the step surface where the first cavity and the second cavity meet.

[0071] The rear end of the wire rope 41 penetrates the second cavity and is connected to the latch 32. In addition, the sheath 42 can also be limited in the inner cavity of the fixed sleeve 31. Specifically, the inner cavity of the fixed sleeve 31 also includes a third cavity connected to the second cavity, and the sheath 42 is inserted and limited in the third cavity.

[0072] When the locking assembly is in the locked state, the end face of the ring abuts against the end wall of the first cavity, and the first elastic member 33 is in a state of preventing loosening or slightly pressing. When the engine hood 5 needs to be closed, that is, when the locking assembly is unlocked, the pull ring 44 is manually pulled, and the wire rope 41 moves forward following the pull ring 44, and the wire rope 41 pulls the latch 32 back and leaves the limiting hole 11, and at the same time presses the first elastic member 33, so that the first elastic member 33 stores energy.

[0073] When the locking assembly is in the unlocked state, the first elastic member 33 is always compressed and stores energy. When the engine hood 5 is opened, the engine hood 5 is manually lifted upward, and the elastic locking member 3 moves relative to the hinge seat 1. During the movement of the elastic locking member 3, the latch 32 always abuts against the outer wall of the hinge seat 1, and the first elastic member 33 is in an energy storage state. When the latch 32 moves to the limiting hole 11, the hinge seat 1 no longer limits the latch 32, and the first elastic member 33 releases its elastic potential energy, pushing the latch 32 to insert into the limiting hole 11.

[0074] The elastic locking member 3 is in the form of a fixing sleeve 31, a latch pin 32 and a first elastic member 33, and has a simple structure, occupies a small space, and is easy to unlock and lock, and has stable performance.

[0075] In order to reduce the friction force when the latch 32 moves relative to the hinge base 1, please refer to Figure 6 In some embodiments, the end surface of the extended end of the latch 32 is a spherical surface protruding toward the hinge seat 1. The outer wall surface of the hinge seat 1 is a plane, and the plane and the spherical surface are in point contact, so the friction is small; in addition, the spherical surface is also easy to embed and extend into the limit hole 11.

[0076] In some embodiments, the latch 32 may be Figure 6 The structure shown, see Figure 6 The latch 32 includes a pin barrel 321, a sphere 322, a contact block 323 and a second elastic member 324. The sphere 322 is partially located in the pin barrel 321 and partially extends out of the pin barrel 321; the contact block 323 is located in the pin barrel 321 and contacts the sphere 322; the second elastic member 324 is located in the pin barrel 321; one end of the second elastic member 324 contacts the contact block 323, and the other end is connected to the pin barrel 321 or the unlocking structure 4.

[0077] A second elastic member 324 is provided in the pin barrel 321 to provide elastic potential energy for the movement of the ball 322 so that the ball 322 always partially extends out of the pin barrel 321, ensuring point contact with the hinge seat 1 with a small contact collision force, thereby further reducing sliding friction.

[0078] See also Figure 6 On the basis of the above embodiment, one end of the unlocking structure 4 passes through the inner cavity of the fixing sleeve 31 and is inserted and limited in the pin cylinder 321, and the other end of the second elastic member 324 abuts against the plug-in end surface of the unlocking structure 4.

[0079] Specifically, the sheath 42 is inserted and limited in the third cavity of the fixing sleeve 31, and the rear end of the wire rope 41 passes through the sheath 42. A fixing block 45 can be provided in the inner cavity of the pin barrel 321, and the fixing block 45 is connected to the rear end of the wire rope 41. The fixing block 45 not only plays the role of fixing the wire rope 41, but also can abut against the second elastic member 324 to limit the installation position of the second elastic member 324.

[0081] The vehicle provided by the utility model adopts the above-mentioned engine hood hinge, which not only can omit the installation of the support rod and optimize the overall structure of the engine hood 5 and the cabin structure, but also facilitates manual unlocking of the locking structure, thereby improving the convenience of opening and closing the engine hood 5 and reducing the cost and weight of the entire vehicle.

[0082] 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.
