Description

Technical Field

[0001] The present invention relates to the field of new energy vehicles, and in particular, to a display platform for new energy vehicle training. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as the power source (or use conventional vehicle fuels and adopt new vehicle power devices), integrating advanced technologies in vehicle power control and drive aspects, forming vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. With the rapid development of new energy vehicle technology, the demand for related technical talents is also increasing day by day. To meet this demand, various display platforms for new energy vehicle training have emerged.

[0003] A display platform for new energy vehicle training is a teaching device used to simulate the operation of new energy vehicles and display the systems and working principles of new energy vehicles. Its main function is to provide students or engineers with opportunities for practical operation to help them better understand the structure and working principles of new energy vehicles. Such a display platform usually includes various main systems of new energy vehicles, such as battery packs, motors, chargers, controllers, etc., and can display the starting, driving, charging, etc. processes of new energy vehicles through simulated operations. Since the display platform includes various systems and components on new energy vehicles, it is large in volume and heavy in weight. When it needs to be carried for display and recycled, it is very troublesome to move, requiring a large amount of manpower and time. Moreover, when the display platform is directly carried, the parts exposed on the display platform are easily damaged due to bumping, resulting in a relatively high risk of damage to the display platform.

[0031] Embodiment 1: A display stand for new energy vehicle training, as Figures 1 - 3As shown in the figure, it includes: a base frame 1, which is a carrier for the installation and movement of the display stand; four universal wheels 11, which are respectively installed at the four top corners of the bottom side of the base frame 1; a receiving box body 2, which is fixedly arranged on the top of the base frame 1; a display cover plate 3, which is rotatably installed at the top of the rear side of the receiving box body 2, and an information display board can be pasted on the inner side of the display cover plate 3; a display board member 4, which is slidably arranged inside the receiving box body 2, and the display board member 4 can extend out or retract into the receiving box body 2; the display board member 4 includes: a lifting bottom plate 41, which is slidably installed inside the receiving box body 2, and the lifting bottom plate 41 is slidably matched with the groove on the inner wall of the receiving box body 2 through the convex block on its side, so that the lifting bottom plate 41 can be horizontally lifted inside the receiving box body 2; a mounting rotating plate 42, which is rotatably installed at the front end of the lifting bottom plate 41, and the mounting rotating plate 42 can be flexibly flipped on the lifting bottom plate 41; a training display stand 5, which is installed on the upper side of the mounting rotating plate 42, and the training display stand 5 is used for the training display of new energy vehicles; a limiting component 6, which is symmetrically installed on the receiving box body 2, and the limiting component 6 is used to limit the display height of the training display stand 5 on the display board member 4, stably support the training display stand 5 through the limiting component 6, and cooperate with the display cover plate 3 to display and introduce information, so as to carry out the training display of new energy vehicles. After the display is completed, the training display stand 5 can be retracted into the receiving box body 2, and the whole display stand can be safely transferred conveniently by the universal wheels 11.

[0032] As Figures 1 - 3 shown, the receiving box body 2 can cooperate with the display cover plate 3 to store and protect the training display stand 5. There is a notch at the top of the rear side wall of the receiving box body 2, and the display cover plate 3 is restricted by the notch. The maximum rotation angle of the display cover plate 3 on the receiving box body 2 is perpendicular to the ground. The left and right side walls at the top of the receiving box body 2 are higher than the front side wall. The display cover plate 3 can be rotated and closed on the receiving box body 2, so that the training display stand 5 stored in the receiving box body 2 is protected during movement. The training display stand 5 is detachably installed on the mounting rotating plate 42. According to the needs of training and displaying different new energy vehicle structures, various training display stands 5 with different structures can be selectively installed on the mounting rotating plate 42 to expand the diversity of the training display of the display stand.

[0033] As Figure 1 、 Figure 3 and Figure 4As shown, the limiting component 6 includes: a pulling plate frame 61 symmetrically penetrating and slidably installed on the left and right side walls of the receiving box body 2; two sets of wedge-shaped blocks 62 symmetrically and fixedly arranged on the inner side of the pulling plate frame 61, and each set of the wedge-shaped blocks 62 has no less than two pieces. The inclined surface of the wedge-shaped block 62 is inclined upward toward the opposite side; linkage racks 63 are respectively symmetrically installed on the bottom side of the pulling plate frame 61, and the linkage racks 63 slide closely against the outer bottom side of the receiving box body 2; a gear disc 64 is rotatably installed on the outer bottom side of the receiving box body 2. A torsion spring is provided on the rotating shaft of the gear disc 64, and the gear disc 64 meshes with the symmetrically arranged linkage racks 63. Initially, under the action of the torsion spring on it, the gear disc 64 drives the pulling plate frame 61 to close in the opposite direction by meshing with the linkage racks 63, so that the pulling plate frame 61 drives the wedge-shaped blocks 62 to be clamped on the display panel 4, thereby realizing the stable limiting and display of the training booth 5. At the same time, pulling one of the pulling plate frames 61 can adjust the support height of the display panel 4, so that the training booth 5 is received into the receiving box body 2.

[0034] Initially, the display board 4 and the training exhibition stand are stored in the receiving box 2. With the universal wheels 11, the base frame 1 and the receiving box 2 can be pushed by a single person. When the receiving box 2 is pushed to a suitable display location, first lock the universal wheels 11 to stably place the entire base frame 1 and the receiving box 2. Then the user manually flips and opens the display cover plate 3. After the display cover plate 3 is supported and fixed, information about new energy vehicles can be posted on the display cover plate 3. By pulling up the training exhibition stand 5 from the receiving box 2, the upward-moving training exhibition stand 5 will drive the display board 4 to move upward synchronously. At this time, the lifting bottom plate 41 will move upward along the inclined surface of the wedge-shaped block 62. The upward-moving lifting bottom plate 41 will squeeze open the wedge-shaped block 62. The wedge-shaped blocks 62 on both sides being squeezed will squeeze and pull the pulling plate frame 61 to open in the direction away from each other. The corresponding linkage racks 63 are driven to slide by the pulling plate frames 61 on both sides that are opened. The two mutually cooperating linkage racks 63 will engage and drive the gear disk 64. The rotating gear disk 64 will continuously compress the torsion spring on its rotating shaft. Under the elastic force of the torsion spring, the pulling plate frames 61 and the linkage racks 63 on both sides will have a restoring force to reset inward. When the upward-moving lifting bottom plate 41 squeezes open and disengages from the topmost wedge-shaped block 62, since the wedge-shaped block 62 is no longer squeezed, the pulling plate frame 61 and the linkage rack 63 as a whole will reset inward under the elastic reset of the gear disk 64, realizing the stable support of the wedge-shaped block 62 for the lifting bottom plate 41. Finally, the mounting turntable 42 is flipped on the lifting bottom plate 41, and by placing a support between the lifting bottom plate 41 and the mounting turntable 42, the mounting turntable 42 will lift the training exhibition stand 5 upward. Cooperating with the display information on the display cover plate 3, the construction of the training display stand can be completed. When the display stand needs to be retracted, similarly, after removing the support, the training exhibition stand 5 is flipped back onto the lifting bottom plate 41 by the mounting turntable 42, and after pulling out the pulling plate frame 61, the training exhibition stand 5 is retracted into the receiving box 2. Finally, the display cover plate 3 is covered back on the receiving box 2, enabling the convenient transfer of the entire display stand through the universal wheels 11 while protecting the training exhibition stand 5.

[0035] Embodiment 2: On the basis of Embodiment 1, as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, a rotating assembly 7 is provided on the rotating shaft of the mounting rotating plate 42. The rotating assembly 7 includes: small gears 71, which are two and symmetrically arranged left and right and are fixedly arranged at both ends of the rotating shaft of the mounting rotating plate 42, and the total number of teeth of the small gears 71 does not exceed 10; fixed bumps 72, which are symmetrically and fixedly installed on the front side wall of the receiving box body 2 corresponding to the small gears 71 respectively. The fixed bumps 72 are used to fit and press the small gears 71. When adjusting the height of the training booth 5 through the display plate member 4, the fixed bumps 72 will press on the corresponding small gears 71, causing the small gears 71 to rotate and drive the mounting rotating plate 42 to flip and support from the lifting bottom plate 41, realizing the automatic flipping of the training booth 5 for display.

[0036] As Figure 1 , Figure 5 and Figure 7 shown, a locking assembly 8 is provided outside the receiving box body 2. The locking assembly 8 includes: a sliding push rod 81, which is slidably installed on the outer side of the top of the receiving box body 2, and both ends of the sliding push rod 81 are slidably attached to the outer side wall of the receiving box body 2 respectively; fixed shafts 82, which are symmetrically and fixedly arranged on the left and right sides of the top of the receiving box body 2, and the fixed shafts 82 are close to the rotating shaft position of the display cover plate 3; T-shaped blocks 83, which are rotatably installed on the fixed shafts 82 respectively. A torsion spring is provided between the fixed shafts 82 and the T-shaped blocks 83. The T-shaped blocks 83 respectively fit the two ends of the sliding push rod 81. Initially, the T-shaped blocks 83 are clamped and restricted in front of the display cover plate 3 under the action of the torsion spring, so that the display cover plate 3 after being vertically flipped and displayed is stably locked by the T-shaped blocks 83. The T-shaped blocks 83 can be rotated by being pressed by the sliding push rod 81, so as to release the locking of the display cover plate 3, enabling the display cover plate 3 to rotate and cover the receiving box body 2.

[0037] Before the display cover plate 3 is flipped and opened from the receiving box body 2, first push the sliding push rod 81 from front to back, so that the two ends on both sides of the sliding push rod 81 squeeze backward on the corresponding T-shaped blocks 83, making the T-shaped blocks 83 rotate around the fixed shaft 82 against the elastic force of the torsion spring on their rotating shafts. After the two sides of the T-shaped blocks 83 rotate, they will no longer block the inside of the receiving box body 2. At this time, the display cover plate 3 can be rotated and opened to the maximum angle, and then the sliding push rod 81 is released. The T-shaped blocks 83 will rotate and reset around the fixed shaft 82 under the action of the torsion spring. After the two sides of the T-shaped blocks 83 rotate and reset, they will be clamped and locked on the front side of the display cover plate 3, so that the display cover plate 3 can be stably maintained in the flipped and opened state to stably display information on the display cover plate 3. When the display plate member 4 drives the training booth 5 to rise, the upward moving mounting rotating plate 42 will drive the two small gears 71 at the end of its rotating shaft to rise synchronously. When the mounting rotating plate 42 moves up to the top opening of the receiving box body 2, the teeth of the upward moving small gears 71 will contact and engage with the corresponding fixed protrusions 72. When the small gears 71 are squeezed by the fixed protrusions 72 and the display plate member 4 rises synchronously, the mounting rotating plate 42 will be driven to rotate and flip around its rotating shaft on the lifting bottom plate 41, and the training booth 5 will be lifted synchronously and flipped. Thus, when the training booth 5 moves up to the top of the receiving box body 2, under the action of the fixed protrusions 72 limiting and squeezing the small gears 71, the training booth 5 can synchronously complete the flipping and stable support work, saving the work of manually flipping the training booth 5 and borrowing a support to support the training booth 5 for display.

[0038] Embodiment 3: On the basis of Embodiment 2, as Figure 1 , Figure 5 and Figure 8As shown, it further includes a lifting component 9, and the lifting component 9 includes: a fixed push rod 91, fixedly arranged at the rear side of the bottom of the display cover plate 3, and the display cover plate 3 can be conveniently rotated through the fixed push rod 91; an L-shaped slide bar 92, symmetrically arranged sliding grooves 21 are formed on the rear side wall of the storage box body 2, two L-shaped slide bars 92 are symmetrically arranged, and are slidably installed on the rear side wall of the storage box body 2 through the corresponding sliding grooves 21, and the lower end of the L-shaped slide bar 92 penetrates into the storage box body 2; a first connecting block 95, symmetrically and fixedly connected to the lower end of the L-shaped slide bar 92 respectively; a second connecting block 96, symmetrically and fixedly connected to the lower side of the lifting bottom plate 41 respectively; a lever member, symmetrically arranged between the first connecting block 95 and the second connecting block 96, and the lever member is used to link the display plate member 4 and the display cover plate 3. By flipping the display cover plate 3, the fixed push rod 91 is synchronously flipped and pressed on the L-shaped slide bar 92, and the descending L-shaped slide bar 92 presses the lever member through the first connecting block 95. Under the lever action of the lever member, the second connecting block 96 moves upward to lift the display plate member 4 and the training booth 5, so as to realize the adaptive lifting and display of the training booth 5 while rotating and opening the display cover plate 3.

[0039] As Figure 1 and Figure 8 As shown, the lever member includes: a support plate 93 and a linkage plate 94. There are two support plates 93 symmetrically arranged left and right and respectively fixedly connected to the bottom side inside the storage box body 2. The linkage plate 94 is correspondingly rotatably installed on the top of the support plate 93. The rotation axis of the linkage plate 94 is its center point. Both ends of the linkage plate 94 are provided with sliding openings. One of the sliding openings is slidably adapted to the first connecting block 95, and the other sliding opening is slidably adapted to the second connecting block 96. The support plate 93 and the linkage plate 94 cooperate to form a lever structure, so that the first connecting block 95 and the second connecting block 96 can move up and down in the opposite direction.

[0040] As Figure 1 As shown, it further includes a lighting fixture 10. The lighting fixture 10 is rotatably installed on the front side top of the display cover plate 3. The lighting fixture 10 is used to illuminate the display cover plate 3 and the training booth 5, so that the display booth can be displayed in a dim environment, and the display effect of the display cover plate 3 and the training booth 5 is improved.

[0041] Initially, when the display board 4 and the training booth 5 are stored inside the housing box 2, the lifting bottom plate 41 will be pressed against the front end of the corresponding linkage plate 94 through the second connecting block 96, causing the front end of the linkage plate 94 to approach the inner bottom side of the housing box 2. Under the lever action formed by the support plate 93 and the linkage plate 94, the rear end of the linkage plate 94 will move away from the inner bottom side of the housing box 2. The rear end of the linkage plate 94 will keep the L-shaped slide bar 92 lifted upward through the first connecting block 95. At this time, the upper end of the L-shaped slide bar 92 will be higher than the top of the housing box 2. When it is necessary to lift and display the training booth 5, first, when the display cover plate 3 is flipped backward to open, the display cover plate 3 will drive the fixed push rod 91 thereon to flip backward synchronously. When the fixed push rod 91 is flipped by a certain angle, it will be pressed against the upper end of the L-shaped slide bar 92. After being pressed, the L-shaped slide bar 92 will slide downward under the limiting and guiding of the chute 21 and drive the first connecting block 95 to press against the rear end of the linkage plate 94, causing the linkage plate 94 to flip around the support plate 93. When the rear end of the support plate 93 moves downward, the rear end of the support plate 93 will move upward under the lever action and push the second connecting block 96 upward. At this time, the second connecting blocks 96 that move upward synchronously on both sides will lift the lifting bottom plate 41 upward and continuously lift the training booth 5 to the top of the housing box 2. Cooperating with the lighting fixture 10 turned on on the display cover plate 3, the training booth 5 has a good display effect. And when the display cover plate 3 is rotated and opened to the maximum angle, the lifting bottom plate 41 can also lift the training booth 5 synchronously through the mounting rotating plate 42, saving the trouble of manually lifting the training booth 5 from the housing box 2 and conveniently realizing the conversion of the display stand from the storage state to the enabled state.

[0042] The above embodiments only represent the preferred implementation modes of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements and substitutions can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
