Description

Technical Field

[0001] The utility model relates to the technical field of chassis installation, in particular to a support plate for a new energy vehicle chassis. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures.

[0003] During the assembly process, a support plate is needed to support the chassis so that workers have enough space and stability to install components on the chassis. However, the size of the support plate is relatively fixed and is not enough to limit larger or smaller chassis. When facing chassis of different sizes, the support plate may be too large to provide support or too small and the base may rotate on the support plate. For this reason, we propose a support plate for the chassis of new energy vehicles. Utility Model Content

[0004] The purpose of the utility model is to provide a support plate for a new energy vehicle chassis to solve the problems raised in the above-mentioned background technology.

[0006] Preferably, the driving assembly includes a driving motor, which is fixed to the outside of the support plate body. An inner cavity is provided in the support plate body, and partitions are symmetrically fixed in the inner cavity. A rotating shaft is provided in the inner cavity for rotation, and the rotating shaft is located between the two partitions. The rotating shaft is fixed to the output end of the driving motor, and a first bevel gear is evenly fixed on the rotating shaft. A plurality of screw rods are symmetrically rotated in the inner cavity, one end of the screw rod rotates with the inside of the inner cavity, and the other end is rotatably connected to the partition. A second bevel gear is fixed on the end of the screw rod close to the partition, and the second bevel gear is meshingly connected to the first bevel gear. A slider is threaded on the screw rod, and the slider is fixed to the end of the movable frame away from the auxiliary support plate. The rotating shaft is driven to rotate by the driving motor, thereby driving all the screw rods to rotate synchronously at the same time, and then the two auxiliary support plates are pushed to move outward or inward at the same time through the movable frame, and the adjustment device can support an area.

[0007] Preferably, there are multiple movable frames, each of which is provided on the outer side of the screw rod, and the outer side of the screw rod cooperates with the movable frame, and each movable frame is composed of two plates, so as to improve the supporting strength of the movable frame to the auxiliary support plate.

The auxiliary support plate contacts the chassis of the new energy vehicle through the rolling roller.

A sink 8 is provided on the top of the auxiliary support plate 5, and a rolling roller 9 is provided for rotation in the sink 8.

[0025] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings:

[0026] See also Figure 1-Figure 5 A support frame 21 is fixed on the base 2, and the height of the support frame 21 is greater than the height of the electric hydraulic cylinder 3 in the retracted state. When not in use, the support plate body 1 is placed on the support frame 21 to alleviate the stress on the electric hydraulic cylinder 3 when the device is not in use. By arranging a driving component 7 in the support plate, the driving component 7 drives the two symmetrically distributed auxiliary support plates 5 to move, and the supporting area of ​​the support plate body 1 is adjusted to support chassis of different sizes.

[0027] The driving assembly 7 includes a driving motor 10, which is fixed on the outside of the supporting plate body 1. The supporting plate body 1 is provided with an inner cavity 11, and a partition 12 is symmetrically fixed in the inner cavity 11. A rotating shaft 13 is rotatably provided in the inner cavity 11, and the rotating shaft 13 is located between the two partitions 12. The rotating shaft 13 is fixed to the output end of the driving motor 10, and a first bevel gear 14 is evenly fixed on the rotating shaft 13. A plurality of screw rods 15 are symmetrically rotated in the inner cavity 11, and one end of the screw rod 15 rotates with the inner cavity 11, and the other end rotates with the partition The plate 12 is rotatably connected, and the end of the screw rod 15 close to the partition 12 passes through the partition 12 and is fixed with a second bevel gear 16. The second bevel gear 16 is meshed and connected with the first bevel gear 14. A slider 17 is threaded on the screw rod 15. The slider 17 is fixed to the end of the movable frame 6 away from the auxiliary support plate 5. The rotating shaft 13 is driven to rotate by the driving motor 10, thereby driving all the screw rods 15 to rotate synchronously at the same time, and then the two auxiliary support plates 5 are pushed to move outward or inward at the same time through the movable frame 6, and the support area of ​​the adjustment device can be adjusted.

[0028] At the same time, there are multiple movable frames 6, and each movable frame 6 is provided on the outside of each screw rod 15. The outside of the screw rod 15 cooperates with the movable frame 6. Each movable frame 6 is composed of two plates to improve the supporting strength of the movable frame 6 to the auxiliary support plate 5. The two plates of the movable frame 6 are symmetrically distributed on the outside of the screw rod 15, one on the left and one on the right, and the movable frame 6 has the strength to resist up and down bending.

[0029] The chassis of the new energy vehicle is placed above the supporting plate body 1, and the rotating shaft 13 is driven to rotate by the driving motor 10, and then the symmetrically distributed second bevel gear 16 is driven to rotate by the first bevel gear 14 on the rotating shaft 13, thereby driving the symmetrically distributed lead screw 15 to rotate, and then the symmetrically distributed slider 17 is driven to move by the threaded action of the lead screw 15, and then the two auxiliary support plates 5 are pushed to move outward or inward at the same time through the movable frame 6 fixed to the slider 17, so as to adjust the support area of ​​the device.

[0030] It is worth noting that Figure 4 As shown, the top height of the auxiliary support plate 5 is smaller than the top height of the support plate body 1, and the highest point of the rolling roller 9 is flush with the top of the support plate body 1. The auxiliary support plate 5 contacts the chassis of the new energy vehicle through the rolling roller 9. When the auxiliary support plate 5 adjusts its position, the friction between the auxiliary support plate 5 and the chassis is reduced when sliding, thereby reducing the wear on the bottom of the chassis.

[0031] In addition, if Figure 2 and Figure 3 As shown, the auxiliary support plate 5 is evenly provided with mounting grooves 18, and a compression spring 19 is fixed in the mounting groove 18. A resist tube 20 is slidably provided in the mounting groove 18. The resist tube 20 is slidably engaged with the mounting groove 18 to prevent the resist tube 20 from shaking in the mounting groove 18. The movable end of the compression spring 19 is fixed inside the resist tube 20. In the process of the auxiliary support plate 5 moving outward, the resist tube 20 first assists the support plate 5 to contact the inner side of the chassis to prevent the auxiliary support plate 5 from excessively squeezing the inner side of the chassis due to too fast movement.
