Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the technical field of vehicle accessories, and particularly to a vehicle hood hinge structure and a vehicle. Background Art
[0002] In traffic accidents, pedestrians are one of the most vulnerable groups. How to effectively protect pedestrian safety has become an important direction in the field of vehicle research and has received increasing attention. According to the investigation report, when a pedestrian collides with a vehicle, due to the relatively soft texture of the outer covering (such as the vehicle front hood, etc.), while the texture of the hood hinge located inside the outer covering is relatively hard, under the action of collision inertia, the pedestrian's head first causes the deformation of the outer covering, and then collides with the hard hood hinge inside it, that is, there is an indirect impact between the pedestrian's head and the hood hinge, resulting in serious head injuries or even fatalities, which is not conducive to protecting pedestrian safety.
[0003] It should be noted that the above content is only used to assist in understanding the technical solution of the present invention, and does not represent an admission that the above content is prior art. Summary of the Utility Model
[0004] In view of this, the embodiments of the present application provide a vehicle hood hinge structure and a vehicle, which can avoid the indirect impact between the pedestrian's head and the hood hinge, thereby effectively protecting pedestrian safety.

Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.
[0034] The embodiments of this application provide a vehicle hood hinge structure. Refer to Figure 1 and Figure 2 , including:
[0035] The hood hinge body 1 is disposed inside an outer covering member (not shown in the drawings).
[0036] The protection bracket 2 is disposed on a side of the hood hinge body 1 facing the outer covering member; a first end of the protection bracket 2 is connected to the hood hinge body 1, and a preset gap 3 is provided between a second end of the protection bracket 2 and the hood hinge body 1.
[0037] In the vehicle hood hinge structure provided by the embodiment of the present application, the protection bracket 2 is disposed on a side of the hood hinge body 1 facing the outer covering member, and a preset gap 3 is provided between a second end of the protection bracket 2 and the hood hinge body 1, and the preset gap 3 is used as a deformation space of the protection bracket 2; it can be understood that since the protection bracket 2 is disposed between the hood hinge body 1 and the outer covering member, when a pedestrian's head indirectly impacts the hood hinge body 1, it will necessarily contact the protection bracket 2 first, and the protection bracket 2 itself has a certain toughness and can generate elastic deformation, and a part of the impact force is offset through its elastic deformation to block the continuous movement of the pedestrian's head in the direction of the hood hinge body 1, thereby avoiding the indirect impact between the pedestrian's head and the hood hinge body 1, and achieving the purpose of effectively protecting the safety of pedestrians.
[0038] It should be noted that for some hood hinge bodies 1, referring to Figure 3 and Figure 4 , the hood hinge body 1 includes a hinge fixed seat 11 and a hinge movable arm 12, and the hinge fixed seat 11 and the hinge movable arm 12 are movably connected by a hinge shaft 13. With such a setting, the hinge fixed seat 11 is fixedly connected to the vehicle body, and the hinge movable arm 12 is connected to the outer covering member. Since the hinge fixed seat 11 and the hinge movable arm 12 are movably connected by the hinge shaft 13, the outer covering member is movably connected to the vehicle body; in the actual operation process, the driver can observe the operation conditions of components such as the engine or the refrigeration system located in the vehicle body by opening the outer covering member (such as the front hood of the vehicle body) to judge whether there is an abnormality in the vehicle. Since the hood hinge body 1 belongs to the prior art, the present application will not elaborate on it in detail.
[0039] It should be noted that for some protection brackets 2, the protection bracket 2 is made of B340 / 590DPD+Z galvanized steel, and the thickness of the protection bracket 2 is 1.2 to 1.8 mm. With such a setting, the B340 / 590DPD+Z galvanized steel has excellent corrosion resistance, high strength and rigidity, a beautiful appearance, good processing performance and environmental protection characteristics, and is widely used in the fields of architecture, transportation, industry and others. In this application, the protection bracket 2 is made of B340 / 590DPD+Z galvanized steel, and its thickness is specifically limited, so as to ensure that the protection bracket 2 has sufficient strength to provide sufficient support force to offset part of the impact force when a pedestrian collides with a vehicle, thereby blocking the continuous movement of the pedestrian's head in the direction of the engine hood hinge body 1.
[0040] In addition, it should also be noted that in the embodiment of this application, referring to Figure 1 and Figure 2 , the first end of the protection bracket 2 is installed on the hinge fixed seat 11, and the second end of the protection bracket 2 covers the connection between the hinge fixed seat 11 and the hinge movable arm 12. With such a setting, considering that if the protection bracket 2 completely covers the entire engine hood hinge body 1, it will inevitably occupy a large amount of body space, which is not conducive to the beautiful appearance of the vehicle; and considering that the connection between the hinge fixed seat 11 and the hinge movable arm 12 is a position where two relatively hard objects overlap, compared with a single hinge fixed seat 11 or a single hinge movable arm 12, the hardness of its connection is higher and the harm to the pedestrian's head is more serious. Based on the above considerations, in this application, the protection bracket 2 is arranged to cover the connection between the hinge fixed seat 11 and the hinge movable arm 12 to focus on protecting its connection and prevent the pedestrian's head from hitting this connection.
[0041] In some embodiments of this application, referring to Figures 3 to 6 , a first mounting plane 111 is provided on the side of the hinge fixed seat 11 facing the outer cover, a second mounting plane 21 is provided at the first end of the protection bracket 2, and the first mounting plane 111 and the second mounting plane 21 are fitted and matched; the vehicle engine hood hinge structure further includes a fixing component 4, and the fixing component 4 is used to be installed on the first mounting plane 111 and the second mounting plane 21 to fixedly connect the hinge fixed seat 11 and the protection bracket 2. With such a setting, through the mutual fitting of the first mounting plane 111 and the second mounting plane 21, a flat mounting plane is provided for the hinge fixed seat 11 and the protection bracket 2, and then the two are connected to each other through the fixing component 4, so that the hinge fixed seat 11 and the protection bracket 2 can be firmly connected and prevent displacement from occurring between them during the operation process.
[0042] It should be noted that in the embodiments of the present application, the specific form of the fixing component 4 is not limited, and it can be configured according to actual conditions. For example, in some embodiments of the present application, the first mounting plane 111 is provided with at least two first rivet holes 112, and the second mounting plane 21 is provided with at least two second rivet holes 211, and the first rivet holes 112 correspond to the second rivet holes 211 one by one; the fixing component 4 includes a rivet 41, and the rivet 41 passes through the first rivet hole 112 and the second rivet hole 211 in sequence to fix the hinge fixing seat 11 and the protective bracket 2. In this way, the rivet 41 passes through the first rivet hole 112 and the second rivet hole 211 in sequence to achieve mutual fixation between the hinge fixing seat 11 and the protective bracket 2, and the structure is simple and practical. At the same time, in order to ensure that the hinge fixing seat 11 and the protective bracket 2 do not move after being fixed, the number of the first rivet hole 112 and the second rivet hole 211 is specifically specified. It is understandable that if there is one first rivet hole 112, the protection bracket 2 may rotate relative to the hinge fixing seat 21 around the first rivet hole 112. In this embodiment, there are two first rivet holes 112, and correspondingly, there are also two second rivet holes 211.
[0043] In some embodiments of the present application, reference Figure 5 and Figure 6 , the second end of the protection bracket 2 is provided with a bending portion 22, and the opening side of the bending portion 22 faces the hood hinge body 1; specifically, the bending portion 22 includes a first plate 221 and a second plate 222, the first end of the first plate 221 is connected to the second mounting plane 21, the second end of the first plate 221 is connected to the second plate 222, and the first plate 221 and the second plate 222 are arranged at an angle. With such arrangement, since in the actual operation process, the elastic deformation position of the protection bracket 2 is mainly concentrated at the second end of the protection bracket 2, the second end is set as the bending portion 22, and the opening side of the bending portion 22 faces the hood hinge body 1, so that the protection bracket 2 has a larger elastic deformation space when subjected to external impact force, ensuring that the protection bracket 2 can provide sufficient support force to offset part of the impact force when a pedestrian collides with a vehicle, thereby blocking the pedestrian's head from continuing to move toward the hood hinge body 1.
[0044] Furthermore, the end of the second plate 222 away from the first plate 221 extends to the upper part of the connection between the hinge fixing seat 11 and the hinge movable arm 12. This arrangement ensures that when the protection bracket 2 is elastically deformed under external impact force, so that the bending portion 22 moves toward the connection between the hinge fixing seat 11 and the hinge movable arm 12, the end of the second plate 222 away from the first plate 221 can cover the upper area of the connection, thereby wrapping the connection and preventing the pedestrian's head from colliding with the connection.
[0045] Further, refer to Figure 5 , a through hole portion 23 is provided in the middle of the connection between the first plate 221 and the second mounting plane 21. In this way, the through hole portion 23 is provided to reduce the connection strength between the first plate 221 and the second mounting plane 21, so that the protection bracket 2 can produce a larger elastic deformation when subjected to external impact force. It can be understood that the through hole portion 23 is used to reduce the connection area between the first plate 221 and the second mounting plane 21, so that the connection strength between the first plate 221 and the second mounting plane 21 is reduced, and then the first plate 221 can produce a larger elastic deformation relative to the second mounting plane 21 when subjected to external impact force.
[0046] Further, refer to Figure 6 The edge side of the protection bracket 2 is provided with a reinforcement frame 24, which extends from the first end of the protection bracket 2 to the second end of the protection bracket 2. In order to prevent the first end and the second end of the protection bracket 2 from being broken due to excessive external impact force, the present embodiment improves the overall strength of the protection bracket 2 by providing the reinforcement frame 24.
[0047] The embodiment of the present application also provides a vehicle, including the vehicle hood hinge structure of any of the above embodiments. For the specific structure of the vehicle hood hinge structure, reference can be made to the above embodiments. Since the vehicle adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.
[0048] It should be noted that the vehicle in this application may refer to a large vehicle, a small vehicle, a special vehicle, etc. For example, according to the vehicle type, the vehicle in this application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV) or other vehicle types. Generally, a vehicle is provided with wheels, a power source, and a transmission system provided between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, so that the wheels rotate, thereby driving the vehicle to travel.
[0049] It should be noted that in the embodiments of the present application, the type of the power source of the vehicle is not limited. For example, for a fuel vehicle, the power source may refer to a fuel engine such as a gasoline engine or a diesel engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; for a vehicle powered by other means, the power source may refer to a device that generates power.
