Description

Technical Field

[0001] This utility model relates to the field of engineering vehicle frame technology, and in particular to a highly reliable and impact-resistant frame. Background Technology

[0002] During the operation of engineering vehicles, the chassis, as the main load-bearing body of the vehicle, needs to withstand the weight of the vehicle itself, the weight of the cargo, and various dynamic loads generated during the journey. At the same time, when encountering impacts such as collisions and bumps, the chassis also needs to have good impact resistance to protect the safety of the personnel and equipment inside the vehicle.

[0003] However, the existing chassis structure of engineering vehicles has some shortcomings: some chassis have insufficient overall strength and are prone to deformation and breakage when used for a long time or subjected to large impacts, affecting the normal use and safety of the vehicle. In addition, in terms of anti-collision design, the existing chassis anti-collision device structure is not reasonable enough and cannot effectively absorb and disperse collision energy, thus providing limited protection for vehicles and personnel.

[0004] To address these issues, a highly reliable and impact-resistant frame is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problem that the overall strength of the frame is insufficient and that it is prone to deformation and breakage when used for a long time or subjected to large impacts, this utility model provides a highly reliable impact-resistant frame.

[0006] This utility model is achieved using the following technical solution:

[0007] A high-reliability impact-resistant vehicle frame includes a main frame, a bottom plate, a tail plate, and side panels. The bottom plate is fixed to the bottom of the main frame, and the tail plate is fixedly connected to the bottom plate. Two side panels are provided and symmetrically fixed to the left and right sides of the bottom plate. A mudguard is provided between the front end of the side panel and the main frame.

[0008] The side panel includes a left main side panel and a right main side panel. The left main side panel is provided with multiple heat dissipation holes. The tail panel is provided with engine mounting holes. The mudguard is provided with tire side panels on its side.

[0009] The main frame includes a front connecting plate, a main board, and side panels. The side panels are symmetrically fixed to both sides of the main board. The front connecting plate is fixed to the front end of the main board. The main board has reinforcing strips at its edges.

[0010] The rear end of the tailgate is equipped with an anti-collision device.

[0011] The anti-collision device includes a crossbeam, an anti-collision beam, and a rear connecting plate. The anti-collision beam includes a left anti-collision beam and a right anti-collision beam. The anti-collision beam is erected vertically. The crossbeam is fixed at the upper end between the left and right anti-collision beams. The rear connecting plate is fixed at the lower end between the left and right anti-collision beams. The bottom of the anti-collision beam is welded and fixed to the upper surface of the tail plate.

[0012] A vertical partition plate is provided between the cross frame and the tail plate. A U-shaped frame is also provided on the upper surface of the cross frame. The top of the anti-collision beam is provided with a lifting lug. An assembly plate is also provided on the upper surface of the cross frame. The assembly plate is fixed to the cross frame with bolts.

[0013] A reinforcing rib is provided between the mudguard and the side wall, and the reinforcing rib is welded and fixed to the mudguard and the side wall. A reinforcing rod is provided on the inner wall of the engine mounting hole.

[0014] The tail plate is also equipped with a mounting platform and a right rear mounting plate. An outer tube is fixedly installed on the left side of the main frame, and a support plate is installed on the top of the mudguard on the right side.

[0015] The present invention has the following advantages over the prior art:

[0016] 1. By installing a collision protection device at the rear of the frame, when a vehicle collides, the crossbar connects the left and right collision protection beams into a whole to jointly bear the impact force. The partition plate deforms during the collision, absorbing some energy and reducing the impact force transmitted to the rear plate and other parts of the frame, enabling the frame to withstand greater loads and impact forces, and effectively protecting the safety of the vehicle and personnel in the event of a collision.

[0017] 2. Multiple heat dissipation holes on the left main side panel increase airflow, which can dissipate the heat generated by the engine and other components in a timely manner, prevent the components from overheating, and extend the service life of the components. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1 to 3 As shown, a high-reliability impact-resistant vehicle frame includes a main frame 1, a base plate 4, a tail plate 17, and side panels. The base plate 4 is fixed to the bottom of the main frame 1, providing a stable support foundation for the entire vehicle frame. The tail plate 17 is fixedly connected to the base plate 4 and can be used to install important components such as the engine. The tail plate 17 is made of high-strength material. The reinforcing rod 15 on the inner wall of the engine mounting hole 11 increases the strength of the mounting hole and prevents deformation of the mounting hole during engine installation and use. When the vehicle is subjected to a rear-end collision, the tail plate 17 transmits the impact force to the anti-collision device 12. The anti-collision device 12 absorbs and disperses energy through structural deformation, reducing damage to other parts of the vehicle frame. There are two side panels, symmetrically fixed on the left and right sides of the base plate 4, which protect the internal components and personnel of the vehicle. A mudguard 3 is provided between the front end of the side panel and the main frame 1, which prevents mud, water, and other debris from splashing into the interior of the vehicle frame.

[0025] The side panels include a left main side panel 9 and a right main side panel 10. The left main side panel 9 is provided with multiple heat dissipation holes 8, which can increase air circulation, effectively dissipate the heat generated by the engine and other components, and improve the heat dissipation performance of the frame. The tail panel 17 is provided with an engine mounting hole 11, which facilitates the installation and fixing of the engine. The mudguard 3 is provided with a tire side panel 6 on its side, which can further protect the tire and the bottom of the frame from damage by debris.

[0026] The main frame 1 includes a front connecting plate 26, a main plate 28, and side panels 30. Two side panels 30 are symmetrically fixed to both sides of the main plate 28, enhancing the overall strength and stability of the main frame 1. The front connecting plate 26 is fixed to the front end of the main plate 28 and can be used to connect the front components of the vehicle. As an important connecting component at the front of the frame, the front connecting plate 26 is mainly used to connect the front components of the vehicle, such as the bumper and front suspension system. It transfers the load of the front components to the main plate 28 of the main frame 1, ensuring the stability and integrity of the front structure of the vehicle. The main plate 28 has reinforcing strips 29 at its edges, further improving its strength and enabling it to withstand greater loads and impacts. The main plate 28 is made of high-strength steel, and its large cross-sectional dimensions and reasonable shape design allow it to withstand greater bending and torsional moments. The reinforcing strips 29 at the edges further enhance the bending resistance of the main plate 28. When the vehicle is subjected to vertical loads or lateral forces, the reinforcing strips 29 can effectively disperse stress and prevent excessive deformation of the main plate 28.

[0027] The rear end of the tail plate 17 is provided with an anti-collision device 12.

[0028] The anti-collision device 12 includes a crossbeam 18, an anti-collision beam, and a rear connecting plate 16. The anti-collision beam includes a left anti-collision beam 24 and a right anti-collision beam 22. The anti-collision beam is vertically erected and can directly withstand the impact force during a collision. The crossbeam 18 is fixed at the upper end between the left anti-collision beam 24 and the right anti-collision beam 22. The rear connecting plate 16 is fixed at the lower end between the left anti-collision beam 24 and the right anti-collision beam 22, forming a stable frame structure. The bottom of the anti-collision beam is welded and fixed to the upper surface of the tail plate 17 to ensure that the anti-collision device 12 is firmly connected to the tail plate 17.

[0029] A vertical partition plate 23 is provided between the cross frame 18 and the tail plate 17. The partition plate 23 can play a certain role in buffering and supporting, and dispersing collision energy. A U-shaped frame 19 is also provided on the upper surface of the cross frame 18. The U-shaped frame 19 can be used to install other components or as a reinforcing structure. The top of the anti-collision beam is provided with a lifting lug 21 to facilitate the hoisting and transportation of the frame. An assembly plate 20 is also provided on the upper surface of the cross frame 18. The assembly plate 20 is fixed to the cross frame 18 with bolts to facilitate the disassembly and installation of other auxiliary equipment.

[0030] A reinforcing rib 13 is provided between the mudguard 3 and the side wall. The reinforcing rib 13 is welded and fixed to the mudguard 3 and the side wall, which enhances the connection strength between the mudguard 3 and the side wall and improves the overall impact resistance of the frame. A reinforcing rod 15 is provided on the inner wall of the engine mounting hole 11. The reinforcing rod 15 can increase the strength of the engine mounting hole 11 and prevent the mounting hole from deforming during the installation and use of the engine.

[0031] The tail plate 17 is also provided with a mounting platform 5 and a right rear mounting plate 14. The mounting platform 5 and the right rear mounting plate 14 can be used to install other vehicle parts, such as storage boxes and tools. An outer tube 2 is also fixedly provided on the left side of the main frame 1. The outer tube 2 can be used to arrange wiring or install other tubular components. A support plate 7 is provided on the top of the mudguard 3 on the right side.
