This part of the structure not only maintains the rigidity, stability and safety of the car body, but also involves the connection with the rear bumper, trunk lid and other related components.

[0004] The rear of a hybrid vehicle may contain high-voltage electrical components (such as a battery pack), and electrical safety needs to be specially considered in the event of a rear-end collision. Some existing rear side panel frames lack corresponding anti-collision mechanisms. In the event of a rear-end collision, high-voltage components such as the battery pack are directly exposed to the impact force, which may cause the battery casing to rupture and the circuit to be damaged, leading to the risk of short circuit, leakage and even fire and explosion, endangering the lives of occupants and rescue personnel in the vehicle. Utility Model Content

[0005] The purpose of the utility model is to provide a rear side panel frame for a hybrid vehicle, which has the advantages of safety and anti-collision, and solves the problem that some existing rear side panel frames lack corresponding anti-collision mechanisms. In the event of a rear-end collision, high-voltage components such as the battery pack are directly exposed to the impact force, which may cause the battery shell to rupture and the circuit to be damaged, causing the risk of short circuit, leakage and even fire and explosion, endangering the lives of passengers and rescue personnel in the vehicle.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a rear side frame for a hybrid vehicle, comprising a frame body and a battery pack fixedly arranged at the rear side thereof, wherein an anti-collision mechanism is arranged outside the battery pack:

[0007] The anti-collision mechanism includes a protective cover fixedly connected to the skeleton body on one side, and clamping plates are provided on the left and right sides of the protective cover respectively, and the opposite sides of the clamping plates are in contact with the left and right sides of the battery pack, and a first rubber plate is slidably connected to the rear side of the battery pack, and a positioning sleeve is fixedly connected to the left and right sides of one side of the first rubber plate, and a sliding rod is slidably connected to the inside of the positioning sleeve, and one end of the sliding rod passes through the positioning sleeve and extends to the outside of the protective cover and is fixedly connected to a baffle.

[0008] As a preferred rear side panel frame for a hybrid vehicle of the utility model, the splint includes a splint shell, a splint cover is provided on one side of the splint shell, a fixed sleeve and a movable rod are fixedly connected to opposite sides of the splint shell and the splint cover respectively, and one end of the movable rod extends into the interior of the fixed sleeve and is slidably connected thereto.

[0009] As a preferred embodiment of the rear side frame for a hybrid vehicle of the utility model, a slide groove is provided below the inner wall of the protective cover, and the slide groove is slidably connected to the bottom of the splint shell.

[0010] As a preferred embodiment of the rear side panel frame for a hybrid vehicle of the utility model, a first spring is fixedly connected between the fixing sleeve and the movable rod.

[0011] As a preferred rear side panel frame for a hybrid vehicle of the utility model, a screw rod is arranged above the interior of the protective cover, one end of the screw rod extends to the outside of the protective cover and is rotatably connected thereto, and a surface of the screw rod is threadedly connected to the clamping plate.

[0012] As a preferred embodiment of the rear side panel frame for a hybrid vehicle of the utility model, a second spring is fixedly connected between the positioning sleeve and the slide rod.

[0013] As a preferred rear side enclosure frame for a hybrid vehicle of the utility model, one end of the slide rod is slidably connected to a plurality of rotating rods, the rotating rods are rotatably connected to one side of the first rubber plate, one end of the rotating rod is rotatably connected to a second rubber plate, and one side of the second rubber plate is slidably connected to the rear side of the inner wall of the protective cover.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. When the rear side of the automobile is hit, the impact force is applied to the baffle and pushes the baffle to slide inside the protective cover. When the baffle slides inside the protective cover, it pushes the first rubber plate to move toward the surface of the battery pack. The first rubber plate can absorb and disperse the impact force due to its own good elastic properties. When hit by external force, the rubber molecular chain will deform and convert kinetic energy into heat energy, thereby greatly weakening the effect of the impact force. When the baffle slides along the protective cover, it drives the sliding rod to slide inside the positioning sleeve. When the sliding rod slides, it can push the rotating rod to rotate. When the rotating rod rotates, it drives the second rubber plate to fit with the rear side of the inner wall of the protective cover. The second rubber plate can further buffer the impact force. When a rear-end collision occurs, the anti-collision mechanism first contacts and absorbs most of the impact force, prevents or reduces the possibility of direct impact on the battery pack, reduces the risk of the battery pack being squeezed, punctured or short-circuited, thereby avoiding safety accidents such as electrical fires or explosions, and can effectively improve the anti-collision performance of the rear side frame, thereby protecting key components of the vehicle from damage, reducing later maintenance costs, and complying with relevant regulations on environmental protection.

[0016] 2. The utility model transfers the impact force from the sliding rod to the first rubber plate through the rotating rod, and then realizes multi-level shock absorption through the sliding connection between the second rubber plate and the inner wall of the protective cover, effectively reducing the direct impact of the impact force on the battery pack, and protecting the battery pack from impact damage.

DETAILED DESCRIPTION

[0024] See also Figure 1-Figure 6 A rear side frame for a hybrid vehicle comprises a frame body 1 and a battery pack 2 fixedly arranged at the rear side thereof, wherein an anti-collision mechanism is arranged outside the battery pack 2:

[0025] Furthermore, the anti-collision mechanism includes a protective cover 3 fixedly connected to the skeleton body 1 on one side, and splints 6 are correspondingly provided on the left and right sides inside the protective cover 3. The opposite side of the splint 6 is in contact with the left and right sides of the battery pack 2. A first rubber plate 7 is slidably connected to the rear side of the battery pack 2, and a positioning sleeve 8 is fixedly connected to the left and right sides of one side of the first rubber plate 7. A sliding rod 9 is slidably connected to the inside of the positioning sleeve 8, and one end of the sliding rod 9 passes through the positioning sleeve 8 and extends to the outside of the protective cover 3 where a baffle 13 is fixedly connected.

[0026] When the rear side of the car is hit, the impact force is applied to the baffle 13 and pushes the baffle 13 to slide into the protective cover 3. When the baffle 13 slides into the protective cover 3, it pushes the first rubber plate 7 to move toward the surface of the battery pack 2. The first rubber plate 7 can absorb and disperse the impact force due to its own good elastic properties. When hit by external force, the rubber molecular chain will deform and convert kinetic energy into heat energy, thereby greatly weakening the effect of the impact force. When the baffle 13 slides along the protective cover 3, it drives the slide bar 9 to slide into the positioning sleeve 8. When the slide bar 9 slides, it can push the rotating rod 11 to When the rotating rod 11 rotates, it drives the second rubber plate 12 to fit with the rear side of the inner wall of the protective cover 3. The second rubber plate 12 can further buffer the impact force. When a rear-end collision occurs, the anti-collision mechanism first contacts and absorbs most of the impact force, thereby preventing or reducing the possibility of direct impact on the battery pack 2, reducing the risk of the battery pack 2 being squeezed, punctured or short-circuited, thereby avoiding safety accidents such as electrical fires or explosions, and can effectively improve the anti-collision performance of the rear side frame, thereby protecting the key components of the vehicle from damage, reducing the subsequent maintenance costs, and complying with relevant regulations on environmental protection.

[0027] Furthermore, the splint 6 includes a splint shell 601, a splint cover 602 is provided on one side of the splint shell 601, and a fixed sleeve 603 and a movable rod 604 are fixedly connected to opposite sides of the splint shell 601 and the splint cover 602 respectively, and one end of the movable rod 604 extends into the interior of the fixed sleeve 603 and is slidably connected thereto.

[0028] The movable rod 604 is a movable component, which is slidably connected to the fixed sleeve 603, which means that it can be extended or slid along the guide rail inside the fixed sleeve 603. The movable rod 604 changes the distance between the splint shell 601 and the splint cover 602 through telescopic movement, and then adjusts the clamping state, so that the battery pack 2 can be effectively fixed between the two splint covers 602.

[0029] Furthermore, a slide groove 4 is opened at the bottom of the inner wall of the protective cover 3, and the slide groove 4 is slidably connected to the bottom of the splint shell 601. The set slide groove 4 facilitates the splint 6 to slide on the left and right sides inside the protective cover 3 following the rotation of the screw rod 5, and can ensure the movement trajectory of the splint 6 when it moves left and right, thereby ensuring the stability of the splint 6 when moving.

[0030] Furthermore, a first spring 605 is fixedly connected between the fixing sleeve 603 and the movable rod 604 .

[0031] The first spring 605 plays an important auxiliary and controlling role, and enhances the stability and functionality of the splint 6 .

[0032] Furthermore, a screw rod 5 is arranged above the inside of the protective cover 3 , one end of the screw rod 5 extends to the outside of the protective cover 3 and is rotatably connected thereto, and the surface of the screw rod 5 is threadedly connected to the clamping plate 6 .

[0033] In order to fix the battery pack 2 between the two clamps 6, the operator can rotate the screw rod 5. When the screw rod 5 rotates, it drives the two clamps 6 to gradually approach the left and right sides of the battery pack 2 until the opposite side of the clamp 6 fits with the left and right sides of the battery pack 2, so as to effectively fix the battery pack 2 between the two clamps 6 and ensure the stability of the clamping effect of the clamp 6.

[0034] Furthermore, a second spring 10 is fixedly connected between the positioning sleeve 8 and the sliding rod 9 .

[0035] When the slide rod 9 slides into the positioning sleeve 8, the second spring 10 will be squeezed. The second spring 10 can absorb part of the impact force, play a buffering and shock-absorbing role, avoid wear of the battery pack 2 caused by hard collision, and effectively protect the battery pack 2, thereby conveniently extending the service life of the battery pack 2.

[0036] Furthermore, one end of the slide rod 9 is slidably connected to multiple rotating rods 11, which are rotationally connected to one side of the first rubber plate 7, and one end of the rotating rod 11 is rotationally connected to a second rubber plate 12, which is slidably connected to the rear side of the inner wall of the protective cover 3.

[0037] The impact force is transferred from the slide bar 9 to the first rubber plate 7 through the rotating rod 11, and then the second rubber plate 12 is slidably connected to the inner wall of the protective cover 3 to achieve multi-level shock absorption, effectively reducing the direct impact of the impact force on the battery pack 2, and protecting the battery pack 2 from impact damage.

[0038] The above are only preferred embodiments of the present invention and are 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.
