Technical Field
[0001] This utility model relates to the field of vehicle technology, and more specifically, to a car front grille lifting device and a car. Background Technology
[0002] Currently, during routine maintenance and repair of the front of conventional trucks, the front cover, as an area that frequently needs to be opened for maintenance, usually needs to be equipped with hinges to facilitate easy opening and closing for routine maintenance and inspection.
[0003] There are two types of openable truck front covers: The first type uses externally visible rotating hinges to connect the front cover and the body panel, with gas springs providing external assistance for opening the front cover and external force support when the front cover is at its extreme position, and a latch for limiting and locking when the front cover is closed; The second type uses concealed hinges to connect the front cover and the body panel, with gas springs providing external assistance for opening the front cover and external force support when the front cover is at its extreme position, and a latch for limiting and locking when the front cover is closed.
[0004] In the first method, the rotating hinge is exposed, which is not aesthetically pleasing, and the opening angle of the front cover is limited. If the opening angle of the front cover is too large, it may interfere with surrounding components. The second method, the concealed hinge, is more aesthetically pleasing, but the opening height of the front cover is not adjustable and is usually limited by the length of the gas spring.
[0005] Regardless of which method is used, the opening height and angle of the front grille are fixed and will be limited. Since drivers have different heights, maintenance may be inconvenient for drivers of different heights.
[0006] Therefore, how to improve the convenience of automobile maintenance has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0007] In view of this, the purpose of this utility model is to provide a car front grille lifting device to improve the convenience of car maintenance.
[0008] Another key aspect of this invention is the disclosure of a vehicle that includes the aforementioned vehicle front hood lifting device.

[0036] The core of this utility model lies in disclosing a car front grille lifting device to improve the convenience of car maintenance.
[0037] Another key aspect of this invention is the disclosure of a vehicle that includes the aforementioned vehicle front hood lifting device.
[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] like Figures 1-2 As shown in the figure, this utility model embodiment discloses a car front grille lifting device, including a four-bar hinge 10 and a lifting gas strut 20.
[0040] Specifically, the four-bar hinge 10 is used to connect the front cover 30 and the front bulkhead sheet metal 40 of the car. The first end of the lifting gas strut 20 is hinged to the front cover 30 of the car. The gear position bracket 11 of the four-bar hinge 10 is provided with a plurality of interconnected gear position slots 1131 arranged along the height direction of the front cover 30 of the car (i.e. the height direction of the car body). The second end of the lifting gas strut 20 is slidably engaged with the gear position bracket 11 to switch between the plurality of gear position slots 1131.
[0041] In practical use, the four-bar hinge 10 preferably includes two. The left and right sides of the front cover 30 are respectively connected to the front bulkhead sheet metal 40 through the four-bar hinge 10, and the lifting gas strut 20 corresponds to the four-bar hinge 10 one by one.
[0042] When the front hood 30 needs to be opened for maintenance, the operator can manually open it. The front hood 30, under an upward force, rises to a certain height, supported by the lifting gas strut 20. If the maintenance space is insufficient, an upward force can be applied to the front hood 30, causing the lifting gas strut 20 to slide along the gear shift bracket 11 towards the upper gear shift slot 1131, thus adjusting the height of the front hood 30.
[0043] The car front cover lifting device disclosed in this embodiment of the utility model has a simple structure and is easy to install. The installation point and structure can be hidden in an invisible part, occupying less space. The appearance is not affected by the structure, making the design more flexible and the cost controllable. The lifting gas strut 20 can realize different opening angles and heights of the car front cover 30 in different gear slots 1131, which can meet the maintenance needs of operators of different heights and improve the convenience of car maintenance.
[0044] Furthermore, such as Figure 2As shown, the four-bar linkage 10 includes a mask connecting bracket 12, a gear shift bracket 11, a first hinge rod 13, and a second hinge rod 14. The mask connecting bracket 12 is connected to the front mask 30 of the car, and the gear shift bracket 11 is connected to the front bulkhead sheet metal 40. The two ends of the first hinge rod 13 are respectively hinged to the mask connecting bracket 12 and the gear shift bracket 11, specifically connected to the end of the mask connecting bracket 12. The two ends of the second hinge rod 14 are respectively hinged to the mask connecting bracket 12 and the gear shift bracket 11, specifically connected to the middle of the mask connecting bracket 12.
[0045] Furthermore, such as Figure 3 As shown, the gear shift bracket 11 includes a first connecting plate 111, a second connecting plate 112, and a third connecting plate 113. The first connecting plate 111 includes a first connecting part and a second connecting part that are respectively connected to the first hinge rod 13 and the second hinge rod 14. The second connecting plate 112 is connected to the front bulkhead sheet metal 40. The gear shift groove 1131 is opened on the third connecting plate 113. There are at least two gear shift grooves 1131. The gear shift groove 1131 shown in the figure includes five gear shift grooves 1131. Each gear shift groove 1131 is arranged at an angle and is a circular arc groove. The circular arc groove can reduce the resistance of sliding of the lifting gas strut 20. The gear shift groove 1131 is generally in the shape of a "comb".
[0046] Furthermore, such as Figure 4 As shown, the second end of the lifting gas strut 20 is provided with a sliding pin 21 and a limiting component. The sliding pin 21 is slidably engaged with the gear position bracket 11, and the limiting component limits the sliding pin 21 to prevent the lifting gas strut 20 from slipping off the gear position bracket 11.
[0047] Specifically, in some specific embodiments, such as Figure 4 As shown, the limiting component includes a threaded portion 211 disposed on the sliding pin 21 and a nut that engages with the threaded portion 211. The threaded portion 211 passes through the stop groove 1131 and engages with the nut threadedly.
[0048] In some other embodiments, the limiting component includes a snap-fit portion disposed on the sliding pin 21 and a snap-fit block that cooperates with the snap-fit portion. The snap-fit portion passes through the stop groove 1131 and is snap-fitted to the snap-fit block.
[0049] Furthermore, the mask connecting bracket 12 can be detachably or non-detachably connected to the front cover 30 of the vehicle, for example, by fasteners (bolts and nuts) or by welding, with the detachable connection method being preferred.
[0050] Furthermore, the gear shift bracket 11 can be detachably or non-detachably connected to the front bulkhead sheet metal 40, for example, by fasteners (bolts and nuts) or by welding, with the detachable connection method being preferred.
[0051] Furthermore, in order to provide a limit locking function for the front grille 30 when closed, such as Figure 1 As shown, a latch 31 is provided on the front cover 30 of the car, and a lock body 41 that cooperates with the latch 31 is provided on the front sheet metal 40. Specifically, the latch 31 is preferably a U-shaped latch, and the lock body 41 is adapted to the latch 31.
[0052] In addition, this utility model also discloses a car, including the car front hood lifting device described in the above embodiment.
