Description

Technical Field

[0001] This invention relates to the field of new energy vehicle grille technology, specifically a multi-level deformation-resistant new energy vehicle grille structure. Background Technology

[0002] As a core component of the front of a vehicle, the grille of a new energy vehicle has undergone a comprehensive transformation in function and form along with the electrification of automobiles. It is an important microcosm of the evolution of the automotive industry from the era of fuel to the era of new energy. The grille was first created in 1903. In the era of fuel vehicles, it was responsible for the functions of engine intake, heat dissipation and component protection. The open and large opening design provided a guarantee for the stable operation of the power system. At the same time, it gradually became a visual symbol that carries the brand's design language.

[0003] With the advancement of electrification, the power system has shifted from internal combustion engines to electric motors and battery packs, significantly reducing the need for heat dissipation. This has led to a structural transformation in grille technology. Existing new energy vehicle grilles, such as the combined automotive grille disclosed in announcement number CN221563004U, involve splitting the grille into two parts using a limiting mechanism during installation. Subsequently, the positioning and limiting mechanisms work together to maintain the grille in a specific unfolded state and constrain it at the front of the grille. The grille has high installation strength and is easy to install. Furthermore, since the grille is installed inside the outer frame of the automotive grille, no extra material adheres to the car's exterior, and it hardly affects the aesthetics of the car's front. In addition, in the above-mentioned prior art, the positioning rod with a tapered top is easier to pass through the holes of the shielding net, and the shielding plate can be temporarily limited to the front side of the net by the constraint and limiting of several positioning rods, which facilitates the installation of the net. However, the aforementioned existing technologies cannot effectively and quickly absorb the kinetic energy of an impact when in use, which can easily lead to deformation. Deformed car grilles not only significantly reduce aesthetics, but also cause abnormal noises during the operation of new energy vehicles. Therefore, a multi-level deformation-resistant grille structure for new energy vehicles is needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-level anti-deformation grille structure for new energy vehicles, in order to solve the problem mentioned in the background art that existing new energy vehicle grilles cannot quickly and effectively absorb the kinetic energy of an impact, resulting in reduced aesthetics and abnormal noises after deformation due to an impact.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A multi-stage deformation-resistant grille structure for new energy vehicles includes a housing and cavities on its rear sides at both ends. The rear sides of the housing are fitted with mounting plates for mounting on a vehicle, and two parallel partitions are also provided on the rear sides of the housing. Each partition has equally spaced mounting slots extending through its two sides, and each mounting slot is axially connected to a support bar. The rear ends of the support bars extend into the cavities, and two mutually attractive magnetic blocks are respectively provided on the front ends of two opposing support bars. The rear ends of the support bars are connected to the inner side of the cavities via a primary energy-absorbing mechanism. The primary energy-absorbing mechanism includes a piston groove disposed on the inner side of the cavity. The front ends of the support bars are connected to the piston groove via a secondary energy-absorbing mechanism, which includes a pressure-bearing rod that movably penetrates the partitions.

[0006] Preferably, the primary energy absorption mechanism further includes a strip-shaped through groove at the rear end of each support bar, with a corresponding T-shaped rod slidingly passing through the strip-shaped through groove. Each cavity has an installation plate inside, and the T-shaped rods are evenly distributed on the corresponding installation plate. A piston plate is seamlessly slidably connected inside the piston groove, and the side of the installation plate facing away from the T-shaped rod is connected to the piston plate through equally distributed installation blocks. A spring is movably nested on the outside of the T-shaped rod between each support bar and the installation plate.

[0007] Preferably, the ratio of the distance from the front end to the rear end of the support bar to its rotation center is not less than 3, and the support bar has an arc-shaped structure.

[0008] Preferably, the support bars and the bearing rods are arranged in a one-to-one correspondence, and the axis of the support bar and the axis of the corresponding bearing rod are on the same horizontal plane.

[0009] Preferably, the secondary energy absorption mechanism further includes a wedge block provided on the rear side of the front end of each support bar, and each wedge block is provided with an arc groove. Each cavity is provided with a piston tube, and the rear end of the corresponding pressure rod extends into the open end of the piston tube. A baffle plate coaxial with the pressure rod is fixedly connected to the part of the pressure rod that extends into the cavity, and a spring II sleeved on the outside of the pressure rod is provided between the baffle plate and the corresponding partition plate.

[0010] Preferably, the inner bottom surface of the arc groove is a smooth arc surface, and the front end of the pressure-bearing rod is provided with a smooth hemispherical structure, and the smooth hemispherical structure slides in contact with the corresponding smooth arc surface.

[0011] Preferably, one-way air inlets are provided on both sides of the housing, and air collection chambers are provided on both ends of the housing. The piston tubes on the same side are all connected to the corresponding air collection chambers, and the air collection chambers are connected to the one-way air inlets.

[0012] Preferably, a rubber ring is provided on the outer side of the rear end of the pressure rod, and the rear end of the pressure rod is seamlessly slidably connected to the inner side of the opening end of the corresponding piston tube through the rubber ring.

[0013] Preferably, the gas collecting chamber and the corresponding piston groove are connected by a gas passage.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the multi-level anti-deformation grille structure of the new energy vehicle can quickly absorb the kinetic energy generated by the impact through the dual energy absorption structure, thereby reducing the possibility of deformation, helping to ensure its aesthetics, and preventing abnormal noises from the new energy vehicle during driving due to deformation. 1. When the car grille is hit, the support bar that first bears the impact will rotate. When it rotates, the attraction of the magnetic block at its front end will absorb part of the impact kinetic energy. Also, when the support bar rotates, the spring will be compressed, thereby absorbing energy. In the above process, since the ratio of the front end and the rear end of the support bar to its rotation center is not less than 3, the spring can offset a large part of the impact kinetic energy. 2. During the rotation of the support bar, the wedge block installed on it will rotate together, thereby squeezing the pressure rod through the arc groove, causing the pressure rod to move. When the pressure rod moves, the second spring is stretched, thereby absorbing energy and further buffering. In addition, when the pressure rod moves, it will squeeze the gas in the piston tube, causing the gas in the piston tube to move into the piston groove through the air passage, so that positive pressure is generated in the piston groove, which can make the piston plate move towards the rear end of the support bar, so that the first spring is further squeezed, thereby helping to absorb more energy. 3. During the operation of a new energy vehicle, air enters the air collection chamber through a one-way air inlet. This avoids structural problems caused by gas loss from the air collection chamber during long-term use of the car's grille. It also allows the pressure rod to move outward toward the piston tube and the front end of the support bar to move toward the direction in which the new energy vehicle is traveling, thereby improving impact resistance and further reducing the possibility of deformation of the car's grille.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-8 The present invention provides the following technical solution: Example 1: To address the problem that traditional new energy vehicle grilles are prone to deformation after impact, leading to unsightly appearance and abnormal noise, the following technical solution is provided: a multi-stage anti-deformation new energy vehicle grille structure, comprising a housing 1 and cavities on its rear sides at both ends. Mounting plates 2 for mounting the housing 1 to the vehicle are installed on the rear side of the housing 1. Two parallel partitions 8 are also provided on the rear side of the housing 1. Each partition 8 has equally spaced mounting grooves 21 penetrating its two sides, and each mounting groove 21 is axially connected to a support bar 3. The rear end of the support bar 3 extends into the cavity, and two mutually attractive magnetic blocks are respectively provided on the front ends of two opposing support bars 3. The rear end of the support bar 3 is connected to the inner side of the cavity through a primary energy absorption mechanism, which includes a piston groove 15 located on the inner side of the cavity. The front end of the support bar 3 is connected to the piston groove 15 through a secondary energy absorption mechanism, which includes a pressure rod 7 that movably penetrates the partition 8.

[0019] The primary energy absorption mechanism also includes a strip-shaped through groove 11 at the rear end of each support bar 3, with a corresponding T-shaped rod 10 slidingly passing through the strip-shaped through groove 11. Each cavity has an installation plate 9 inside, and the T-shaped rods 10 are evenly distributed on the corresponding installation plate 9. A piston plate 14 is seamlessly slidably connected inside the piston groove 15, and the side of the installation plate 9 facing away from the T-shaped rod 10 is connected to the piston plate 14 through equally distributed installation blocks 13. A spring 12 is movably nested on the outside of the T-shaped rod 10 between each support bar 3 and the installation plate 9. The ratio of the front end and rear end of the support bar 3 to its rotation center is not less than 3, and the support bar 3 has an arc-shaped structure. The support bar 3 and the pressure rod 7 are arranged in a one-to-one correspondence, and the axis of the support bar 3 and the axis of the corresponding pressure rod 7 are on the same horizontal plane.

[0020] according to Figures 1-4 If an object accidentally makes a slight impact on the grille of a new energy vehicle during use, and the impact point is on the support bar 3, the support bar 3 will rotate due to the impact. When the support bar 3 rotates, its rear end will squeeze the spring 12, causing the spring 12 to be compressed. Through the compression of the spring 12, some of the kinetic energy generated by the impact can be absorbed. In addition, since the ratio of the distance from the front end to the rear end of the support bar 3 to its rotation center is not less than 3, the spring 12 can absorb more kinetic energy.

[0021] The secondary energy absorption mechanism also includes a wedge block 5 set on the rear side of the front end of each support bar 3, and each wedge block 5 is provided with an arc groove 6. Each cavity is provided with a piston tube 18, and the rear end of the corresponding pressure rod 7 is inserted into the open end of the piston tube 18. A baffle 19 coaxial with the pressure rod 7 is fixedly connected to the part of the pressure rod 7 that extends into the cavity. A spring 20 sleeved on the outside of the pressure rod 7 is provided between the baffle 19 and the corresponding partition 8. The inner bottom surface of the arc groove 6 is a smooth arc surface. The front end of the pressure rod 7 is provided with a smooth hemispherical structure, and the smooth hemispherical structure slides in contact with the corresponding smooth arc surface.

[0022] according to Figures 5-8 During the rotation of the support bar 3, the wedge block 5 on it will rotate along with it; When the wedge block 5 rotates, the arc groove 6 on it will squeeze the pressure rod 7, causing the pressure rod 7 to move on the corresponding partition 8; When the pressure rod 7 moves, the outer spring 20 will be stretched, thereby further absorbing the kinetic energy generated by the impact and further preventing the deformation of the car grille.

[0023] Example 2: To solve the problem in Example 1 where the gas in the piston groove 15 slowly overflows with the use of new energy vehicles, resulting in insufficient gas inside for a long time, thus failing to ensure the stable compression of the support strip 3 by the mounting plate 9, the following technical solution is provided: One-way air inlets 4 are provided on both sides of the housing 1, and air collection chambers 17 are provided on both ends of the housing 1. The piston tubes 18 on the same side are all connected to the corresponding air collection chambers 17, and the air collection chambers 17 are connected to the one-way air inlets 4.

[0024] A rubber ring is provided on the outer side of the rear end of the pressure rod 7, and the rear end of the pressure rod 7 is seamlessly slidably connected to the inner side of the opening end of the corresponding piston tube 18 through the rubber ring. The gas collecting chamber 17 and the corresponding piston groove 15 are connected through the air passage 16.

[0025] according to Figures 5-6 When the pressure rod 7 moves, the rubber ring on it can compress the gas in the piston tube 18, which in turn causes some of the gas in the piston tube 18 to enter the piston groove 15 through the air passage 16, thereby increasing the air pressure in the piston groove 15. When the air pressure in the piston groove 15 is increased, it will push the piston plate 14 to move towards the position of the support bar 3, thereby squeezing the spring 12 and driving the support bar 3 to return to its original position. At this time, because the support bar 3 is not only subjected to the kinetic energy generated by the impact, but also to a force in the opposite direction to the impact kinetic energy, it will offset part of the impact kinetic energy, thereby further preventing the deformation of the car grille. In addition, during the operation of the new energy vehicle, external air enters the air collection chamber 17 through the one-way air inlet 4. This not only avoids the problem of slow gas overflow in the piston groove 15, which would reduce the impact resistance of the support strip 3, but also ensures that the front end of the support strip 3 has a tendency to rotate in the direction of the new energy vehicle's movement, thereby helping to improve its impact resistance.
