Technical Field

[0001] The utility model relates to the technical field of automobile frames, in particular to a lightweight automobile frame with a plurality of mounting surface structures. Background Art

[0002] In the process of the continuous development of the automotive industry, the design and manufacture of automotive frames has always been a key research area. As consumers' requirements for automotive performance, fuel efficiency and safety continue to increase, the traditional single-mounting surface automotive frame design has gradually exposed many limitations. In the past, automotive frames usually adopted a simple structure with fewer and fixed mounting surfaces, which resulted in limited flexibility in the installation of parts. During the assembly process, a large number of adjustments and modifications to the parts are often required, which not only increases production time and cost, but may also affect the accuracy and quality of assembly.

[0003] In the prior art, the mounting surface structure on the automobile frame is relatively fixed, and the position of the mounting surface cannot be flexibly adjusted according to the configuration requirements of different vehicle models to adapt to the installation of parts of different specifications and models and improve the versatility of the automobile frame. At the same time, since there are fewer structural components on the side of the automobile frame, compared with the front and rear of the vehicle, the ability to withstand impact is relatively weak. In the case of a side collision, the distance between the passenger and the collision point is relatively close, leaving less space for buffering and energy absorption. To this end, the utility model provides a lightweight automobile frame with multiple mounting surface structures. Utility Model Content

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a lightweight automobile frame with multiple mounting surface structures, including a frame body, two collision buffer components are arranged on both sides of the outer wall of the frame body for collision buffering of the frame body, and two mounting components are arranged on both sides of the inner wall of the frame body;

[0013] Beneficial Effects

[0014] The utility model provides a lightweight automobile frame with multiple mounting surface structures. Compared with the prior art, it has the following beneficial effects:

[0015] (1) The lightweight automobile frame with multiple mounting surface structures is provided with a collision buffer component on the side of the frame body. When the side is hit, the collision box is squeezed, and the collision box drives the collision plate to compress the spring damper. The compression process of the spring damper can absorb part of the collision energy. The elastic deformation of the spring damper can convert the kinetic energy of the collision into the elastic potential energy of the spring, thereby reducing the impact force directly transmitted to the passengers in the car. At the same time, when the collision plate is squeezed, it will drive the two support rods to approach each other, and then drive the two sliders to approach each other, causing squeezing and compression of the first spring, converting the kinetic energy of the collision into the elastic potential energy of the first spring, thereby reducing the impact force directly transmitted to the passengers in the car. The mutual cooperation of the two can buffer the collision and absorb energy, thereby reducing the damage caused to the passengers in the case of a side collision.

[0016] (2) The lightweight automobile frame with multiple mounting surface structures can move the mounting panel when it is necessary to adjust the position of the mounting panel and adjust the components to meet the requirements of different vehicle configurations. The mounting panel drives the moving block and the sliding plate to slide in the mounting shell. Since a rolling pulley is provided at the bottom of the moving block, the friction of the mounting panel when sliding is reduced. At the same time, a large number of second through holes are provided on the mounting plate. When the mounting panel is moved to a suitable position, the first through hole on the sliding plate can be aligned with the nearby second through hole, and then the sliding plate can be fixedly installed on the mounting plate by bolts and nuts. The movement and fixation of the mounting panel can be completed, and the position of the components can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides two technical solutions:

The frame body 1 can be made of some high-strength lightweight materials to meet the lightweight and safety requirements of the frame body 1;

[0027] The collision buffer assembly 2 includes a collision box 21, a fixing rod 22 is fixedly installed on the inner wall of the collision box 21, two sliders 24 are movably sleeved on the outer wall of the fixing rod 22, a first spring 23 is fixedly installed between opposite sides of the two sliders 24, the first spring 23 is sleeved on the outer wall of the fixing rod 22, and when the sliders 24 are squeezed, the two sliders 24 will squeeze the first spring 23;

[0028] The mounting assembly 3 includes a mounting shell 31, and a slide groove 32 is provided at the top of the inner wall of the mounting shell 31. A collision plate 26 is fixedly mounted on the inner wall of the collision box 21, and a group of spring dampers 27 are fixedly mounted between the collision plate 26 and the inner wall of the collision box 21. The spring damper 27 is a prior art. When a collision occurs, the spring can absorb part of the impact force, and the damping element further absorbs energy through the friction and oil flow inside it. Two second hinge seats 29 are fixedly mounted on the bottom end of the collision plate 26. The two second hinge seats 29 are respectively rotatably mounted with support rods 25. The ends of the two support rods 25 away from the collision plate 26 are both rotatably mounted with first hinge seats 28. The two first hinge seats 28 are respectively fixedly connected to the two sliders 24. When the collision plate 26 is squeezed, it will drive the two support rods 25 to approach each other, and then drive the two sliders 24 to approach each other, causing compression and compression of the first spring 23, converting the kinetic energy of the collision into the elastic potential energy of the first spring 23, thereby reducing the impact force directly transmitted to the passengers in the vehicle.

[0029] Figure 1-Figure 6A second embodiment is shown, which is mainly different from the first embodiment in that a sliding plate 37 is movably inserted into the inner wall of the slide groove 32, a moving block 33 is fixedly installed at the bottom end of the sliding plate 37, a mounting panel 36 is fixedly installed on one side of the outer wall of the moving block 33, a square groove 34 is opened at the bottom end of the moving block 33, a pulley 35 is rotatably installed on the inner wall of the square groove 34, the pulley 35 is in contact with the bottom end of the inner wall of the mounting shell 31, and the pulley 35 reduces the friction when the mounting panel 36 moves, and support plates 311 are fixedly installed on both sides of the outer wall of the sliding plate 37, and the two support plates 311 are arranged to fit the top of the mounting shell 31. The sliding plate 37 can be supported so that the sliding plate 37 is more stable when sliding. A first through hole 38 is penetrated through the outer wall of the sliding plate 37. A mounting plate 39 is fixedly installed on the top of the mounting shell 31. A group of second through holes 310 are penetrated through the outer wall of the mounting plate 39. A group of second through holes 310 matches the first through holes 38. The sliding plate 37 and the mounting plate 39 are fixedly connected by bolts and nuts. When the mounting panel 36 is moved to a suitable position, the first through hole 38 on the sliding plate 37 can be aligned with the nearby second through hole 310, and then the sliding plate 37 can be fixedly installed on the mounting plate 39 by bolts and nuts.

[0030] The two crash boxes 21 are both fixedly connected to the skeleton body 1 , and the two mounting shells 31 are both fixedly connected to the skeleton body 1 .

[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] During operation, when it is necessary to adjust the position of the mounting panel 36 and adjust the components to meet the requirements of different vehicle configurations, the mounting panel 36 can be moved, and the mounting panel 36 drives the moving block 33 and the sliding plate 37 to slide in the mounting shell 31. Since a rolling pulley 35 is provided at the bottom of the moving block 33, the friction of the mounting panel 36 during sliding is reduced. At the same time, a large number of second through holes 310 are provided on the mounting plate 39. When the mounting panel 36 is moved to a suitable position, the first through hole 38 on the sliding plate 37 can be aligned with the nearby second through hole 310, and then the sliding plate 37 can be fixedly installed on the mounting plate 39 by bolts and nuts, so as to complete the movement and fixation of the mounting panel 36 and adjust the position of the components. A collision buffer assembly 2 is provided on the side of the skeleton body 1. When the side is collided, the collision box 21 is squeezed, and the collision box 21 drives the collision plate 26 to compress the spring damper 27. During the compression process, the spring damper 27 can absorb part of the collision energy. The elastic deformation of the spring damper 27 can convert the kinetic energy of the collision into the elastic potential energy of the spring, thereby reducing the impact force directly transmitted to the passengers in the car. At the same time, when the collision plate 26 is squeezed, it will drive the two support rods 25 closer to each other, and then drive the two sliders 24 closer to each other, causing squeezing and compression of the first spring 23, and converting the kinetic energy of the collision into the elastic potential energy of the first spring 23, thereby reducing the impact force directly transmitted to the passengers in the car. The mutual cooperation between the two can buffer and absorb the collision, reducing the damage caused to the passengers in the event of a side collision.
