Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy profiles, in particular to an aluminum alloy profile for automobile frames. Background Art

[0002] The weight of a car is an important factor that restricts the driving distance of new energy vehicles. The application of lightweight technology can reduce the weight of the entire vehicle. Therefore, the lightweighting of the body frame has become a key issue that needs attention. The battery tray accounts for a large proportion of the frame of new energy vehicles, so the battery tray usually chooses low-density and high-strength materials such as aluminum alloy profiles to make the battery tray.

[0003] However, when the existing aluminum alloy profiles for automobile frames are assembled and docked with batteries, the battery pack is usually stuck in a deep slot in the profile. When the battery pack is taken out from the slot, since most of the battery pack shell is embedded in the slot, it is not convenient to use force when taking out the battery pack, which makes it troublesome and time-consuming to separate the battery pack from the aluminum profile. In addition, the existing aluminum profiles and battery packs are usually rigidly connected, so that the vibration of the aluminum profile will be directly transmitted to the battery pack, which is easy to cause the battery pack to vibrate and shake, which has an adverse effect on the performance of the battery pack and easily shortens the life of the battery pack.

[0004] The purpose of the utility model is to provide an aluminum alloy profile for automobile frame to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aluminum alloy profile for an automobile frame, comprising a tray, an inner wall of the tray is fixedly connected with a partition, second plywood is provided on both sides of the partition, a first plywood is provided on the inner side of the tray, shock-absorbing springs are provided on one side of the first plywood and the second plywood, a card box is provided on the side of the first plywood and the second plywood away from the shock-absorbing spring, vertical rods are fixedly connected on both sides of the bottom end of the card box, a horizontal plate is provided at the bottom of the vertical rod, a torsion plate is fixedly connected to the bottom end of the horizontal plate, and card blocks are fixedly connected to the outer walls of the four sides of the tray.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 4 As shown, the aluminum alloy profile for the automobile frame of this embodiment includes a tray 1, the inner wall of the tray 1 is fixedly connected with a partition 7, and the two sides of the partition 7 are provided with a second plywood 5, the inner side of the tray 1 is provided with a first plywood 3, and the first plywood 3 and the second plywood 5 are provided with a shock-absorbing spring 6 on one side, and a card box 4 is provided on the side of the first plywood 3 and the second plywood 5 away from the shock-absorbing spring 6, and the two sides of the bottom end of the card box 4 are fixedly connected with vertical rods 9, and the bottom of the vertical rod 9 is provided with a horizontal plate 10, and the bottom end of the horizontal plate 10 is fixedly connected with a torsion plate 11, and the four side outer walls of the tray 1 are fixedly connected with card blocks 2.

[0024] Specifically, a groove is provided inside the tray 1 for accommodating the card box 4 and the first clamping plate 3 as well as the second clamping plate 5 and the partition 7, and at the same time, the top of the groove is flush with the top of the card box 4, so that the integrity of the aluminum alloy profile is better when used, and the partition 7 is used to separate the battery packs in different positions so that there is enough space between the battery packs for shock absorption and heat dissipation to extend the service life of the battery packs, and the second clamping plate 5 is used to fit and clamp one side of the card box 4, and the first clamping plate 3 is used to fit and clamp the other side of the card box 4, and at the same time, the side wall of the card box 4 is not easy to contact and bump with the inner wall of the tray 1, thereby reducing the probability of the battery pack being vibrated and shaken in the aluminum alloy profile, and the length, width and thickness of the first clamping plate 3 and the second clamping plate 5 are the same, and the shock-absorbing spring 6 is used to reduce the vibration transmitted to the card box 4 by the tray 1, thereby reducing the vibration of the battery pack in the card box 4, and the top of the card box 4 The top and both sides are not closed, so that the battery pack can be smoothly placed in the card box 4. At the same time, the card box 4 plays the role of embedding the entire battery pack as a whole in the card slot corresponding to the tray 1, thereby facilitating the subsequent overall removal of the battery pack in the card slot. The role of the vertical rod 9 is to connect the cross plate 10 and the card box 4, and at the same time strengthen the connection relationship between the card box 4 and the tray 1, so that the card box 4 is more stable when placed in the tray 1. The role of the cross plate 10 is to limit the bottom end of the vertical rod 9 to prevent the vertical rod 9 from accidentally sliding out of the slide 8. When the card box 4 is placed in the tray 1, the bottom can always fit with the bottom of the inner side of the tray 1. The role of the twisting plate 11 is to facilitate the user to twist the cross plate 10, so that the cross plate 10 can change from a state perpendicular to the slide 8 to a state parallel to the slide 8, thereby realizing that the bottom end of the card box 4 is pushed up by the vertical rod 9, and the role of the card block 2 is to enable the aluminum alloy profile to be fixedly connected to other frames of the vehicle body.

[0025] Furthermore, a side wall of the first clamp plate 3 is fixedly connected to one end of a shock-absorbing spring 6, and one end of the shock-absorbing spring 6 away from the first clamp plate 3 is fixedly connected to the inner wall of the tray 1. The first clamp plate 3 is movably connected to the tray 1 via the shock-absorbing spring 6. The first clamp plate 3 can prevent the side wall of the card box 4 from colliding with the inner wall of the tray 1, thereby reducing the vibration of the battery pack in the card box 4.

[0026] Furthermore, one side wall of the second clamp plate 5 is fixedly connected to one end of the shock-absorbing spring 6, and one end of the shock-absorbing spring 6 away from the second clamp plate 5 is fixedly connected to the partition 7. The second clamp plate 5 is movably connected to the partition 7 through the shock-absorbing spring 6. The function of the second clamp plate 5 is to prevent the side wall of the card box 4 from colliding with the side wall of the partition 7, thereby reducing the probability of vibration and shaking of the battery pack in the card box 4 due to collision.

[0027] Furthermore, the card box 4 is movably connected to the first clamp plate 3 and the second clamp plate 5 through the shock-absorbing spring 6. The card box 4 can be clamped between the first clamp plate 3 and the second clamp plate 5, so that the connection relationship between the card box 4 and the tray 1 is changed from a rigid connection to a flexible connection, which is more conducive to shock-proof protection of the battery pack.

[0028] Furthermore, a slide 8 is provided at the bottom end of the tray 1, and a vertical rod 9 is movably connected to the slide 8. The vertical rod 9 slides along the slide 8, so that the sliding of the card box 4 between the first clamping plate 3 and the second clamping plate 5 is limited, thereby increasing the stability of the card box 4 when the tray 1 is vibrated.

[0029] Furthermore, a rotating shaft 12 is installed at the top of the transverse plate 10, and the rotating shaft 12 is rotatably connected to the vertical rod 9. The transverse plate 10 is movably connected to the vertical rod 9 through the rotating shaft 12. The function of the rotating shaft 12 is to facilitate the change of the angle of the transverse plate 10, so that the transverse plate 10 can fit with the bottom of the pallet 1 after passing through the slide 8, thereby facilitating the connection between the transverse plate 10 and the pallet 1.

[0030] Furthermore, balls 13 are movably embedded on both sides of the top of the transverse plate 10. The balls 13 are movably connected to the bottom of the tray 1 through the transverse plate 10 and the slide 8. The surface of the balls 13 is smooth. The function of the balls 13 is to convert the sliding friction between the transverse plate 10 and the tray 1 into rolling friction, thereby reducing the wear generated when the transverse plate 10 and the tray 1 are in contact.

[0031] The method of using the present embodiment is as follows: when using the aluminum alloy profile for the automobile frame, first put the battery pack into the card box 4, and then put the card box 4 into the corresponding deep groove in the tray 1. At this time, the two side walls of the card box 4 are respectively fitted with the side walls of the first clamping plate 3 and the second clamping plate 5, and at the same time, the horizontal plate 10 and the twisting plate 11 at the bottom end of the vertical rod 9 will pass through the slide 8 to the bottom of the tray 1, and then the twisting plate 11 can be twisted to make the horizontal plate 10 rotate along the bottom end of the vertical rod 9 through the rotating shaft 12, so that the horizontal plate 10 and the slide 8 are in a mutually perpendicular state, and at the same time, the two side round beads 13 on the top of the horizontal plate 10 will fit with the bottom of the tray 1, and at this time, the card box 4 and the battery pack are fixed on the tray. On the plate 1, when the tray 1 encounters external force and generates horizontal vibration, the partition 7 and the shock-absorbing spring 6 on the inner wall of the tray 1 will act on the first clamp plate 3 and the second clamp plate 5 respectively, so that the card box 4 clamped by the side walls of the first clamp plate 3 and the second clamp plate 5 can maintain a relatively stable state, so that the battery pack in the card box 4 is not easily shaken due to vibration. When the battery pack needs to be taken out, it is only necessary to rotate the horizontal plate 10 to a position parallel to the slide 8, and then push the horizontal plate 10 upward so that the horizontal plate 10 enters the slide 8, and push the vertical rod 9 upward so that the card box 4 slides out from between the first clamp plate 3 and the second clamp plate 5. At this time, the battery pack and the card box 4 will be taken out from the tray 1.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
