[0002] At present, there are two main ways to open the engine hood in the automobile market: manual opening and electric opening. Considering the cost and the frequency of use of the engine hood, manual opening is the mainstream opening method. Among them, manual opening of the engine hood requires human-machine verification to meet the comfort of opening and closing the engine hood. For the design stage, there is only one form of human-machine verification of the opening height of the engine hood, which makes the opening height of the engine hood impossible to adjust.

[0003] However, the opening height of the existing engine hood cannot be adjusted, and the user market ranges from women to men, from Asia to Europe, and the heights of different user groups are also different. This may lead to the embarrassment of being unable to close the engine hood due to insufficient height, or personal injury caused by hitting the head due to being too tall. As a result, the opening height of the engine hood cannot meet the needs of all users, resulting in customer complaints. Utility Model Content

[0010] Furthermore, the first connecting rod includes a main body portion hinged between the rotating arm and the fixed seat, and a stop arm arranged at the end of the main body portion; the stop arm is located at one end of the main body portion hinged to the fixed seat, and extends in a direction away from the rotating arm; the adjusting member is arranged on the swinging path of the stop arm, and can form a blockage for the swinging of the stop arm.

[0011] Furthermore, an adjusting member mounting plate is formed on the fixing seat; the adjusting member includes a first bolt screwed on the adjusting member mounting plate, and the head of the first bolt constitutes a block for the block arm; the blocking position of the first bolt on the block arm changes with the screwing depth of the first bolt.

[0012] Furthermore, the axis of the first bolt is arranged along the swing tangent direction of the barrier arm.

[0013] Furthermore, the bottom end of the second connecting rod is hinged to the middle part of the fixing seat, and the engine hood hinge also includes a limiting member arranged at the rear part of the fixing seat; when the engine hood is closed in place, the limiting member abuts against the second connecting rod.

[0014] Furthermore, the second connecting rod is bent, the middle portion of the second connecting rod protrudes toward the rear of the vehicle, and a boss is provided at the protruding portion of the second connecting rod, and the boss is abutted and matched with the limiting member.

[0015] Furthermore, a limiting member mounting plate is formed at the rear end of the fixing seat; the limiting member includes a second bolt screwed on the limiting member mounting plate, and the head of the second bolt abuts against the boss.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] The engine hood hinge described in the utility model, through the cooperative arrangement of the swing mechanism and the adjusting part, can limit the swing of the swing mechanism through the adjusting part after the engine hood is opened, so as to limit the opening angle and the opening height of the engine hood, that is, the front edge of the engine hood is limited to a fixed height, and the position of the adjusting part on the swing path is adjustable, so as to realize the adjustment of the opening angle and the opening height of the engine hood, thereby solving the embarrassment of being unable to close the engine hood due to insufficient height, or the problem of personal injury caused by hitting the head due to being too tall, and meeting the needs of people of different heights for opening and closing the engine hood.

[0018] In addition, the swing mechanism includes a first link and a second link, and the rotating arm, the first link, the second link and the fixed seat form a four-link hinge structure, which can make the turning of the rotating arm have high precision, high stability and high reliability, which is conducive to ensuring its fixed motion trajectory and action angle, thereby improving the reliability of the opening of the engine hood.

[0046] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0047] Embodiment 1

[0048] The present embodiment relates to an engine hood hinge, which, under the premise of meeting regulations and human-machine calibration standards, can achieve height adjustment of the front edge of the engine hood, thereby reducing the embarrassment of users being unable to close the hood due to insufficient height, or personal injury caused by hitting their heads due to being too tall, so as to adapt to the needs of users of different heights to open and close the hood, thereby improving the quality of the entire vehicle.

[0049] In terms of overall structure, Figures 1 to 10 As shown, the engine hood hinge of this embodiment includes a fixing seat 5 for connecting to the vehicle body frame, a rotating arm 1 for connecting to the engine hood, and an adjusting member 6 arranged on the fixing seat 5.

[0050] In addition, the rotating arm 1 can be connected to the fixing seat 5 by flipping relative to the fixing seat 5 through a swinging mechanism. The adjusting member 6 is arranged on the swinging path of the swinging mechanism during the opening process of the engine hood to form a restriction on the opening angle of the engine hood, and the position of the adjusting member 6 on the swinging path is adjustable.

[0051] It can be understood that in this embodiment, the opening angle of the engine hood is restricted by the adjusting member 6, that is, the opening height of the engine hood (front edge) is restricted, so as to fix the engine hood at the corresponding opening angle and opening height. At the same time, the position of the adjusting member 6 on the swinging path is adjustable, and the change of the adjustment position can also be used to realize the opening of the engine hood at different angles and heights.

[0052] When implementing it, Figure 5 As shown, the rotating arm 1 of this embodiment is provided with a first mounting hole 11 for connecting with the engine hood, and the number and arrangement of the first mounting holes 11 can be set and adjusted according to the actual installation requirements with the engine hood, for example, there are specifically two of them arranged at intervals along the extension direction of the rotating arm 1.

[0053] Also, see Figure 8 As shown, the fixing seat 5 of this embodiment is also provided with second mounting holes 55 for connecting to the vehicle body frame. The number and arrangement of the second mounting holes 55 can be set and adjusted according to the actual connection requirements with the vehicle body frame. For example, the second mounting holes 55 are specifically arranged as two or three holes arranged at intervals.

[0054] Based on the above overall introduction, in this embodiment, as a preferred implementation form, Figure 1 As shown, the swing mechanism includes a first connecting rod 2 and a second connecting rod 3 that are spaced apart, and the rotating arm 1, the first connecting rod 2, the second connecting rod 3 and the fixing seat 5 form a four-link hinge structure.

[0055] The advantage of such a configuration is that the turning of the rotating arm 1 can be made with high precision, high stability and high reliability, which is conducive to ensuring its fixed motion trajectory and action angle, thereby improving the precision and reliability of the engine hood opening.

[0056] Specifically, in this embodiment, both ends of the first connecting rod 2 are respectively hinged to the rotating arm 1 and the fixing seat 5 , and both ends of the second connecting rod 3 are also respectively hinged to the rotating arm 1 and the fixing seat 5 , so as to form a four-link hinge structure.

[0057] To achieve the above-mentioned hinged arrangement, see Figure 1 and Figures 5 to 8 As shown, the rotating arm 1 is provided with a first hinge hole 12 for connecting to the first connecting rod 2, and a second hinge hole 13 for connecting to the second connecting rod 3, and the fixing seat 5 is provided with a first connecting hole 53 for connecting to the first connecting rod 2, and a second connecting hole 54 for connecting to the second connecting rod 3.

[0058] In addition, a first hinge fitting hole 22 for cooperating with the first hinge hole 12 and a first connection fitting hole 23 for cooperating with the first connection hole 53 are respectively provided at both ends of the first connecting rod; a second hinge fitting hole 31 for cooperating with the second hinge hole 13 and a second connection fitting hole 32 for cooperating with the second connection hole 54 are respectively provided at both ends of the second connecting rod.

[0059] At the same time, the rotating arm 1 of this embodiment is still Figure 5 As shown, it can be configured as an L-shape consisting of a horizontal plate and a vertical plate, wherein the horizontal plate is disposed on the top of the vertical plate, and the first mounting hole 11 is disposed on the horizontal plate, and the first hinge hole 12 and the second hinge hole 13 are disposed on the vertical plate.

[0060] See also Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, as a preferred implementation form, the first link 2 is arranged on the side of the second link 3 facing the front of the vehicle, and the adjusting member 6 is arranged on the swing path of the first link 2. In this way, the opening angle and opening height of the engine hood (that is, the height of the front edge of the engine hood) can be limited by limiting the first link 2, so that the layout is reasonable, the structure is simple, and the structural stability is higher.

[0061] Furthermore, in this embodiment, combined with Figure 1 and Figure 6 As shown, as a preferred implementation form, the first connecting rod 2 includes a main body portion 20 hinged between the rotating arm 1 and the fixing seat 5, and a stop arm 21 provided at the end of the main body portion 20.

[0062] The blocking arm 21 is located at one end of the main body 20 hingedly connected to the fixing seat 5, and is extended in a direction away from the rotating arm 1, that is, the blocking arm 21 and the main body 20 are respectively arranged on both sides of the first connecting hole 53. The adjusting member 6 is arranged on the swinging path of the blocking arm 21, and can form a block for the swinging of the blocking arm 21. The setting of the blocking arm 21 here is conducive to the blocking and limiting of the first connecting rod 2 by the adjusting member 6, and has a simple structure and reasonable layout.

[0063] It is worth mentioning that in this embodiment, if necessary, a reinforcement structure can be provided on the first link 2 to improve the structural strength of the first link 2, thereby facilitating improving the overall structural strength of the engine hood hinge. For example, reinforcing ribs can be arranged on the first link 2.

[0064] In addition, in this embodiment, as a preferred implementation form, Figure 8 and Fig. 9 As shown, an adjusting member mounting plate 52 is formed on the fixing seat 5 , and the adjusting member mounting plate 52 can be formed integrally with the fixing seat 5 , for example, partially bent and formed with the fixing seat 5 .

[0065] Furthermore, the adjusting member 6 comprises a first bolt screwed on the adjusting member mounting plate 52, and the head of the first bolt blocks the blocking arm 21. The blocking position of the first bolt on the blocking arm 21 changes with the screwing depth of the first bolt.

[0066] It can be understood that the adjusting member 6 adopts a first bolt, and the first bolt is screwed on the adjusting member mounting plate 52 of the fixing seat 5. This is not only conducive to adjusting the blocking position of the blocking arm 21 by the adjusting member 6 through the adjustment of the screwing position of the first bolt, that is, to adjusting the opening angle and opening height of the engine hood, but also has a simple structure, and is conducive to layout and cost reduction.

[0067] Of course, it should be noted that the threading depth of the first bolt in this embodiment refers to the position of the first bolt relative to the adjustment member mounting plate 52, and as the threading depth changes, the blocking position of the first bolt on the barrier arm 21 changes, which also leads to changes in the maximum opening angle and maximum opening height of the engine hood.

[0068] In specific implementation, in this embodiment, as a preferred implementation form, the axis of the first bolt is arranged along the swing tangent direction of the blocking arm 21. Thus, the first bolt can directly and effectively offset the swing force of the blocking arm 21, and improve the blocking reliability of the blocking arm 21.

[0069] If necessary, a nut that cooperates with the first bolt to be locked can also be provided in this embodiment to improve the stability of the first bolt on the adjustment member mounting plate 52.

[0070] In addition, in this embodiment, as a preferred implementation form, see Figure 1 and Figure 7 As shown, the bottom end of the second connecting rod 3 is hinged to the middle of the fixing seat 5, and the engine hood hinge also includes a limiter 4 arranged at the rear of the fixing seat 5, and when the engine hood is closed, the limiter 4 abuts against the second connecting rod 3.

[0071] By setting the limiter 4, the second connecting rod 3 can be limited when the engine hood is closed, thereby preventing the rear corner from collapsing at the moment the engine hood is opened and closed, or the rear corner from interfering with the body during the bumping of the vehicle, thereby improving the structural stability.

[0072] To elaborate, in this embodiment, as a preferred implementation form, the second connecting rod 3 is bent, the middle part of the second connecting rod 3 protrudes toward the rear of the vehicle, and a boss 30 is provided on the protruding part of the second connecting rod 3, and the boss 30 is abutted and cooperated with the limit member 4.

[0073] Such arrangement can make the second connecting rod 3 have a good abutment and matching effect with the stopper 4, and improve the abutment reliability of the two. In the specific structure, the boss 30 can be integrally formed with the second connecting rod 3, for example, it is formed by bending the middle part of the second connecting rod 3.

[0074] Furthermore, in this embodiment, as a preferred implementation form, Figure 1 , Figure 8 Fig.10 As shown, the rear end of the fixing seat 5 is formed with a limit member mounting plate 51. The limit member 4 includes a second bolt screwed on the limit member mounting plate 51, and the head of the second bolt abuts against the boss 30.

[0075] It can be understood that the limit member 4 adopts a second bolt screwed on the limit member mounting plate 51 of the fixed seat 5, and the blocking position of the boss 30 by the limit member 4 can be adjusted by adjusting the screwing position of the second bolt, so as to ensure the structural stability of the rear corner of the engine hood at the moment of closing. At the same time, it also has a simple structure, and is conducive to layout and cost reduction.

[0076] It is still worth mentioning that the first bolt and the second bolt of this embodiment can both be bolts or screws familiar to those skilled in the art, and can be provided with nuts when necessary to ensure the stability of the connection between the first bolt and the adjusting member mounting plate 52 and between the second bolt and the limiting member mounting plate 51.

[0077] Moreover, in the present embodiment, the swivel arm 1 of the hood hinge can be driven to rotate by lifting the front edge of the hood, and as the swivel arm 1 rotates, the hood can be opened and closed with the cooperation of the first link 2 and the second link 3, wherein the adjustment member 6 can limit the maximum opening angle or maximum height of the hood, the limit member 4 can ensure the overall stability of the structure at the moment of opening and closing the hood, and the first link 2 and the second link 3 also have the effect of improving the Y-direction stiffness of the hood hinge.

[0078] The engine hood hinge of this embodiment, when in the closed state, Figure 1 As shown, the boss 30 on the second connecting rod 3 abuts against the stopper 4. When opening, the position of the first bolt can be adjusted according to the height of the user so that the hood hinge is Figure 3 half-open state as shown, or Figure 4 The fully open state is shown, wherein the semi-open state corresponds only to one screw connection position of the first bolt. As the depth of the first bolt increases (the distance between the head of the first bolt and the adjustment member mounting plate 52 decreases), the opening angle of the engine hood hinge increases, that is, the opening angle and opening height of the engine hood increase.

[0079] The hood hinge of the present embodiment, through the cooperative arrangement of the swing mechanism and the adjusting member 6, can limit the swing of the swing mechanism through the adjusting member 6 after the hood is opened, so as to limit the opening angle and opening height of the hood, that is, to limit the front edge of the hood at a fixed height, and the position of the adjusting member 6 on the swing path is adjustable, and the opening angle and opening height of the hood can also be adjusted, thereby solving the embarrassment of users being unable to close the hood due to insufficient height, or causing personal injury due to hitting their heads due to being too tall, and meeting the needs of users of different heights to open and close the hood, thereby improving the quality of the entire vehicle.
