Description

Technical Field

[0001] This application relates to the technical field of auto showrooms, and in particular to a new energy vehicle showroom. Background Technology

[0002] New energy vehicles refer to automobiles powered by electricity. Compared to traditional gasoline-powered vehicles, new energy vehicles have advantages such as environmental friendliness, energy conservation, and low carbon emissions. As a future trend in automotive development, new energy vehicles are receiving increasing attention. With the rapid development of new energy vehicles, venues showcasing these vehicles and their technologies are also becoming an important demand.

[0003] The new energy vehicle exhibition hall has multiple booths where new energy vehicles are displayed for easy viewing. To get a more complete view of the vehicles, visitors often walk around the booths. However, when there are many visitors in the hall, collisions can easily occur, potentially leading to accidents. Summary of the Invention

[0004] To address the issue of potential collisions among exhibitors in a showroom, this application provides a new energy vehicle exhibition hall.

[0005] The technical solution provided in this application for a new energy vehicle exhibition hall adopts the following:

[0006] A new energy vehicle exhibition hall includes several display stands. Each display stand includes a base plate and a display disc. A jack is installed at the center of the top surface of the base plate. A connecting plate is rotatably installed on the bottom surface of the display disc. The top support of the jack abuts against the bottom surface of the connecting plate. A rotating sleeve is fixed to the bottom surface of the display disc. A synchronous sleeve is fixed to the top surface of the base plate. The synchronous sleeve is sleeved on the outer circumference of the rotating sleeve and can be locked and fixed with the rotating sleeve. A rotating component for pushing the synchronous sleeve to rotate is provided on the base plate.

[0007] By adopting the above technical solution, the jack is activated, and the top support of the jack abuts tightly against the bottom surface of the connecting plate, pushing the connecting plate upward. This, in turn, causes the display disc to move upward, thus raising the new energy vehicle so that all exhibitors in the exhibition hall can observe it. Then, the synchronous sleeve and the rotating sleeve are locked together and fixed. The rotating component drives the synchronous sleeve to rotate, which in turn drives the rotating sleeve to rotate. The rotating sleeve drives the display disc to rotate, which in turn drives the new energy vehicle to rotate. This allows exhibitors to observe the new energy vehicle comprehensively from the same spot, reducing the possibility of collisions during the movement of exhibitors.

[0008] Preferably, a plurality of lifting rods are installed on the top surface of the base plate, the lifting rods are spaced apart along the circumference of the base plate, two fixing plates are fixed at the top of the lifting rods, and an abutment roller is rotatably installed between the two fixing plates. The axial direction of the abutment roller is arranged along the radial direction of the base plate, and the outer circumferential surface of the abutment roller can abut against the bottom surface of the display disc.

[0009] By adopting the above technical solution, the lifting rod drives the fixed plate and the abutment roller to move upward, so that the abutment roller abuts against the bottom surface of the display disc, thereby supporting the display disc and keeping it horizontal during the upward movement of the display disc.

[0010] Preferably, the lifting rod includes a lifting sleeve and a threaded rod passing through the lifting sleeve. The lifting sleeve and the threaded rod are threadedly connected. The lifting sleeve is fixedly connected to the fixing plate. A guide block is fixed at the bottom of the lifting sleeve. A guide plate is fixed on the top surface of the base plate. A guide groove is provided on the side of the guide plate. The guide block slides vertically with the guide plate through the guide groove.

[0011] By adopting the above technical solution, the guide block moves vertically in the guide groove, thereby limiting the lifting sleeve. When the threaded rod rotates, it drives the lifting sleeve to move upward, which in turn drives the abutting roller to move upward, so that the abutting roller and the display disc remain in contact.

[0012] Preferably, a gear one is fixedly fitted onto the outer circumferential surface of the threaded rod, a rotating ring is rotatably mounted on the base plate, an external gear ring is fixedly fitted onto the outer circumferential surface of the rotating ring, the gear one meshes with the external gear ring, an internal gear ring is fixedly fitted onto the inner circumferential surface of the rotating ring, a drive rod is rotatably mounted on the base plate, a gear two is fixedly fitted onto the outer circumferential surface of the drive rod and meshes with the internal gear ring, and a motor one is mounted on the base plate, the output end of the motor one being fixedly connected to the end of the drive rod.

[0013] By adopting the above technical solution, motor one is started, motor one drives the drive rod to rotate, the drive rod drives gear two to rotate, gear two drives the rotating ring to rotate through the internal gear ring, the rotating ring drives several gears one to rotate synchronously through the external gear ring, gear one drives the threaded rod to rotate, thereby causing several lifting sleeves to move upward.

[0014] Preferably, the inner circumferential surface of the synchronizing sleeve has two snap-fit ​​grooves, and the synchronizing sleeve slides radially along its own snap-fit ​​block through the snap-fit ​​grooves. The outer circumferential surface of the rotating sleeve has a rotating groove for inserting the snap-fit ​​block.

[0015] By adopting the above technical solution, after the display disc moves upward to a certain height under the action of the jack, the locking block is inserted into the rotating groove, and the synchronous sleeve drives the rotating sleeve to rotate, which in turn drives the display disc to rotate, so that the exhibitors can conduct a comprehensive observation of the new energy vehicle.

[0016] Preferably, a slider is fixed to the side of the locking block, and a sliding groove is formed on the inner wall of the locking groove. The slider slides and engages with the synchronous sleeve along the radial direction of the synchronous sleeve through the synchronous sleeve. A locking spring is fixed to the side of the slider away from the rotating sleeve, and the end of the locking spring away from the slider is fixedly connected to the inner wall of the sliding groove. A magnetic block is fixed to the side of the locking block away from the rotating sleeve, and an electromagnet is fixed to the inner wall of the locking groove away from the locking block. The electromagnet can attract the magnetic block.

[0017] By adopting the above technical solution, when the display disc moves upward to a certain height, the display disc stops moving and the synchronous sleeve is rotated. When the synchronous sleeve rotates until the locking groove is aligned with the rotating groove, the locking block is inserted into the rotating groove under the elastic force of the locking spring, so that the rotating sleeve can drive the synchronous sleeve to rotate. When the display disc needs to stop rotating, the electromagnet is energized, and the electromagnet attracts the magnetic block. The magnetic block drives the locking block to move away from the rotating sleeve, and the locking block disengages from the rotating groove.

[0018] Preferably, the inner circumferential surface of the synchronizing sleeve is provided with a plurality of buffer grooves, and a buffer block is installed on the synchronizing sleeve by sliding along its own radial direction through the buffer grooves. A rubber pad is fixed on the side of the buffer block near the rotating sleeve.

[0019] By adopting the above technical solution, after the locking block releases the limit on the rotating sleeve, the rotating sleeve continues to rotate under the action of inertia, and the buffer block abuts against the outer peripheral surface of the rotating sleeve, and the rubber pad is in contact with the outer peripheral surface of the rotating sleeve, thereby slowing down the rotation of the rotating sleeve and keeping it stationary.

[0020] Preferably, a reset block is fixed to the side of the buffer block, and a reset groove is formed on the inner wall of the buffer groove. The reset block slides and engages with the synchronous sleeve radially along the synchronous sleeve through the reset groove. A buffer spring is fixed to the side of the reset block away from the rotating sleeve, and one end of the buffer spring away from the reset block is fixedly connected to the inner wall of the reset groove. A connecting rope is fixed to the side of the buffer block away from the rotating sleeve, and one end of the connecting rope away from the buffer block is fixedly connected to the side of the snap-fit ​​block away from the rotating sleeve.

[0021] By adopting the above technical solution, when the snap-fit ​​block is inserted into the rotating groove, the buffer block maintains a gap with the outer circumferential surface of the rotating sleeve under the tension of the connecting rope; when the snap-fit ​​block is released from the rotating groove under the attraction of the electromagnet, the connecting rope loosens, and the buffer block moves towards the rotating sleeve under the elastic force of the buffer spring, so that the rubber pad abuts against the outer circumferential surface of the rotating sleeve.

[0022] Preferably, the rotating assembly includes a rotating rod rotatably mounted on the base plate, a second motor is mounted on the base plate, the output end of the second motor is fixedly connected to the end of the rotating rod, a third gear is fixedly sleeved on the outer circumferential surface of the rotating rod, and a fourth gear is fixedly sleeved on the outer circumferential surface of the synchronizing sleeve, with the third gear and the fourth gear meshing with each other.

[0023] By adopting the above technical solution, after the display disc moves upward to a certain height, motor two is started. Motor two drives the rotating rod to rotate, the rotating rod drives gear three to rotate, gear three drives gear four to rotate, and then drives the synchronous sleeve to rotate. When the synchronous sleeve rotates until the locking groove is aligned with the rotating groove, the locking groove is inserted into the rotating groove under the elastic force of the locking spring. The synchronous sleeve drives the rotating sleeve to rotate synchronously, and then drives the display disc to rotate.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Start the jack. The top support of the jack will tightly abut against the bottom surface of the connecting plate and push the connecting plate upward, thereby driving the display disc upward, thus raising the new energy vehicle so that all exhibitors in the exhibition hall can observe it. Then, lock the synchronous sleeve and the rotating sleeve together and use the rotating component to drive the synchronous sleeve to rotate. The synchronous sleeve drives the rotating sleeve to rotate, which in turn drives the display disc to rotate. The display disc then drives the new energy vehicle to rotate, allowing exhibitors to observe the new energy vehicle from the same spot and reducing the possibility of collisions during the movement of exhibitors.

[0026] 2. When the display disc moves upward to a certain height, it stops moving. The synchronous sleeve is rotated. When the synchronous sleeve rotates until the locking groove is aligned with the rotating groove, the locking block is inserted into the rotating groove under the elastic force of the locking spring, so that the rotating sleeve can drive the synchronous sleeve to rotate. When the display disc needs to stop rotating, the electromagnet is energized. The electromagnet attracts the magnetic block, and the magnetic block moves the locking block away from the rotating sleeve, and the locking block disengages from the rotating groove.

[0027] 3. When the snap-fit ​​block is inserted into the rotating groove, the buffer block maintains a gap with the outer circumferential surface of the rotating sleeve under the tension of the connecting rope; when the snap-fit ​​block is released from the rotating groove under the attraction of the electromagnet, the connecting rope loosens, and the buffer block moves towards the rotating sleeve under the elastic force of the buffer spring, so that the rubber pad abuts against the outer circumferential surface of the rotating sleeve.

The top support of the jack 13 abuts against the bottom surface of the connecting plate 14. When the jack 13 is activated, the top support of the jack 13 abuts against the connecting plate 14, causing the display disc 12 to move upward.

[0036] Reference Figure 2 and Figure 3 A plurality of lifting rods 2 are installed on the top surface of the base plate 11, and the lifting rods 2 are spaced apart along the circumference of the base plate 11.

Two fixing pieces 26 are fixed on the top surface of the lifting sleeve 21, and an abutment roller 27 is rotatably installed between the two fixing pieces 26. The axial direction of the abutment roller 27 is arranged radially along the base plate 11, and the outer circumferential surface of the abutment roller 27 can abut against the bottom surface of the display disc 12.

[0037] Reference Figure 2 A rotating ring 3 is rotatably mounted on the base plate 11, and an external gear ring 31 is fixedly fitted onto the outer circumference of the rotating ring 3. A gear 33 is fixedly fitted onto the outer circumference of the threaded rod 22, and the gear 33 meshes with the external gear ring 31. A drive rod 35 is rotatably mounted on the base plate 11, and a gear 34 is fixedly fitted onto the outer circumference of the drive rod 35. An internal gear ring 32 is fixedly fitted onto the inner circumference of the rotating ring 3, and the internal gear ring 32 meshes with the gear 34. A motor 36 is mounted on the base plate 11, and the output end of the motor 36 is fixedly connected to the top end of the drive rod 35.

[0038] Start motor 36, which drives drive rod 35 to rotate. Drive rod 35 drives gear 34 to rotate. Gear 34 drives gear 33 to rotate through rotating ring 3, which in turn drives several threaded rods 22 to rotate synchronously. Lifting sleeve 21 moves upward, and abutting roller 27 abuts against the bottom surface of display disc 12, thereby keeping display disc 12 in a horizontal state during the upward process.

[0039] Reference Figure 2 and Figure 4A rotating sleeve 4 is fixed to the bottom surface of the display disc 12, and a synchronizing sleeve 41 is fixed to the top surface of the base plate 11. The synchronizing sleeve 41 is fitted around the outer circumference of the rotating sleeve 4. A vertically mounted rotating rod 42 is rotatably installed on the base plate 11, and a second motor 43 is mounted on the base plate 11. The output end of the second motor 43 is fixedly connected to the top end of the rotating rod 42. A third gear 44 is fitted and fixed to the outer circumference of the rotating rod 42, and a fourth gear 45 is fitted and fixed to the outer circumference of the synchronizing sleeve 41. The fourth gear 45 and the third gear 44 mesh with each other.

[0040] Reference Figure 2 and Figure 5 The inner circumferential surface of the synchronizing sleeve 41 has two symmetrical locking grooves 51. A locking block 5 is mounted on the synchronizing sleeve 41 by sliding radially through the locking grooves 51. The outer circumferential surface of the rotating sleeve 4 has a rotating groove 52 for inserting the locking block 5. Slider blocks 53 are fixed to both sides of the locking block 5. A sliding groove 54 is formed on the inner wall of the locking groove 51. The sliders 53 slide and engage with the synchronizing sleeve 41 radially. A locking spring 55 is fixed to the side of the slider 53 away from the rotating sleeve 4, and the end of the locking spring 55 away from the slider 53 is fixedly connected to the inner wall of the sliding groove 54. A magnetic block 56 is fixed to the side of the locking block 5 away from the rotating sleeve 4, and an electromagnet 57 is fixed to the inner wall of the locking groove 51 away from the locking block 5. The electromagnet 57 can attract the magnetic block 56.

[0041] When the display stand 1 rises to a certain height and stops, motor 2 43 is started. Motor 2 43 drives the rotating rod 42 to rotate, the rotating rod 42 drives the gear 3 44 to rotate, the gear 3 44 drives the gear 45 to rotate, and the gear 45 drives the synchronous sleeve 41 to rotate. When the synchronous sleeve 41 rotates until the locking groove 51 is aligned with the rotating groove 52, the locking block 5 is inserted into the rotating groove 52 under the elastic force of the locking spring 55. The synchronous sleeve 41 drives the rotating sleeve 4 to rotate, which in turn drives the display disc 12 to rotate. When the display disc 12 needs to stop rotating, electromagnet 1 57 is energized. Electromagnet 1 57 attracts the magnetic block 1 56, the locking block 5 disengages from the rotating groove 52, and the limiting of the rotating sleeve 4 is released.

[0042] Reference Figure 2 and Figure 5The inner circumferential surface of the synchronizing sleeve 41 has four buffer grooves 61. A buffer block 6 is mounted on the synchronizing sleeve 41 by sliding radially along its own axis through the buffer grooves 61. A rubber pad 62 is fixed to the side of the buffer block 6 near the rotating sleeve 4. A reset block 63 is fixed to each side of the buffer block 6. A reset groove 64 is formed on the inner wall of the buffer groove 61. The reset block 63 slides and engages with the synchronizing sleeve 41 radially through the reset groove 64. A buffer spring 65 is fixed to the side of the reset block 63 away from the rotating sleeve 4. One end of the buffer spring 65 away from the reset block 63 is fixedly connected to the inner wall of the reset groove 64. A connecting rope 66 is fixed to the side of the buffer block 6 away from the rotating sleeve 4. One end of the connecting rope 66 away from the buffer block 6 is fixedly connected to the side of the locking block 5 away from the rotating sleeve 4.

[0043] When the snap-fit ​​block 5 is inserted into the rotating groove 52, the snap-fit ​​block 5 limits the buffer block 6 through the connecting rope 66, so that the rubber pad 62 and the rotating sleeve 4 maintain a distance; when the snap-fit ​​block 5 is disengaged from the rotating groove 52, the snap-fit ​​block 5 abuts against the outer circumferential surface of the rotating sleeve 4 under the elastic force of the snap-fit ​​spring 55, so that the rotating sleeve 4 slowly stops rotating.

[0044] The implementation principle of a new energy vehicle exhibition hall according to an embodiment of this application is as follows: The jack 13 and motor 36 are started, and both the display disc 12 and the lifting sleeve 21 move upward. The abutting roller 27 abuts against the bottom surface of the display disc 12, thereby keeping the display disc 12 horizontal during its upward movement. After the display disc 12 stops rising, motor 43 is started, which drives the synchronous sleeve 41 to rotate. The locking block 5 is inserted into the rotating groove 52, and the synchronous sleeve 41 drives the rotating sleeve 4 to rotate. The rotating sleeve 4 drives the display disc 12 to rotate, so that exhibitors can make a comprehensive observation of the new energy vehicles on the display disc 12.
