Description

Technical Field

[0001] The utility model relates to the technical field of vehicle exhibition stands, in particular to an exhibition stand and a display component. Background Art

[0002] With the rapid advent of the new energy vehicle era, competition in the automotive market is fierce. Major OEMs are promoting their products and technological advantages to consumers through various channels, including press conferences and auto shows. At major domestic auto shows like the Beijing, Shanghai, Chengdu, and Guangzhou Auto Shows, showcasing new technologies, concepts, and processes through automotive architecture displays has become a major trend among OEMs in promoting new automotive technologies in the new energy vehicle era.

[0003] Generally, auto frame displays are made by applying multiple rounds of sanding, painting, and polishing to the vehicle frame. Due to their lengths exceeding five meters and weights of 2.5 to 3 tons, these displays are also expensive, costing as much as two to three million yuan. Therefore, they place extremely high demands on handling over short distances and in small spaces. This is especially true in narrow roads or exhibition venues, where access is limited, leaving no room for forklifts. Alternatively, the surface's load-bearing capacity prevents forklifts from overrunning and damaging the pavement. In these situations, a mobile base (exhibit stand) at the bottom of the display is required to facilitate short-distance transport from point A to point B. During this process, the weight of the auto frame display and the limitations of the pavement can easily damage the wheels. Damage to the wheels can cause the support provided by the wheels to become unbalanced, rendering them inoperable and reducing mobility efficiency. Utility Model Content

A preset equilibrium position 19 is provided on the display frame 1 , and at least one of the moving devices can slide to the preset equilibrium position 19 .

[0030] The exhibition stand of the present application includes a display frame 1, which is used to carry exhibits (vehicles or vehicle-mounted exhibits); a moving device is provided at the bottom of the display frame 1, specifically, the moving device includes a driving wheel 2 and / or a driven wheel 3, such as if all the wheels on the display frame 1 are driving wheels 2, and the display frame 1 is moved by a plurality of driving wheels 2; or, if all the wheels on the display frame 1 are driven wheels 3, and the display frame 1 is moved by relying on an external force to push the display frame 1; or, if the wheels on the display frame 1 are driving wheels 2 and driven wheels 3, and the display frame 1 is moved by cooperating with the driving wheels 2 and the driven wheels 3; preferably, the wheels on the display frame 1 of the present application are driving wheels 2 and driven wheels 3. Since the display frame 1 carries the exhibits, the exhibits on the display frame 1 can be moved under the action of the moving device (driving wheels 2 and driven wheels 3). The moving device (driving wheel 2 and / or driven wheel 3) is slidably arranged on the display frame 1. In addition, a preset equilibrium position 19 is provided on the display frame 1, and the driving wheel 2 and / or driven wheel 3 can slide to the preset equilibrium position 19. Specifically, Figure 1 As shown, the X direction is the length direction of the display frame 1 and the display device, and the Y direction is the width direction of the display frame 1 and the display device. The display frame 1 is provided with a driving wheel 2 and four driven wheels 3. Every two driven wheels 3 form a row along the Y direction, and there are two rows in total. The row close to the driving wheel 2 is called the first row, and the row far away from the driving wheel 2 is called the second row. When one of the driven wheels 3 in the first row is damaged and cannot work, the normal driven wheels 3 in the first row can be moved along the Y direction to the position shown in FIG. Figure 1The middle position of the dashed box, i.e. the preset balance position 19 (the middle position of the two driven wheels 3 in the first column), prevents the damaged wheel from causing the exhibition stand to lose balance, so as to ensure that the exhibition frame 1 can still be smoothly moved to the destination, and the wheels (two wheels) in the first column and the wheels (one wheel) in the second column can still form a triangular support structure to prevent the exhibition frame 1 from tilting, avoiding the phenomenon that the exhibition frame 1 loses balance due to the damage of the wheels, and improving the moving efficiency of the exhibition stand. When one of the driven wheels 3 in the second column is damaged and cannot work, the normal driven wheel 3 in the second column can be moved to the position shown in the dashed box along the Y direction, i.e. the preset balance position 19 (the middle position of the two driven wheels 3 in the second column), so as to prevent the damaged wheel from causing the exhibition stand to lose balance, so as to ensure that the exhibition frame 1 can still be smoothly moved to the destination, and the wheels (two wheels) in the first column and the wheels (one wheel) in the second column can still form a triangular support structure to prevent the exhibition frame 1 from tilting, avoiding the phenomenon that the exhibition frame 1 loses balance due to the damage of the wheels, and improving the moving efficiency of the exhibition stand. Figure 1 The middle position of the dashed box, i.e. the preset balance position 19 (the middle position of the two driven wheels 3 in the first column), prevents the damaged wheel from causing the exhibition stand to lose balance, so as to ensure that the exhibition frame 1 can still be smoothly moved to the destination, and the wheels (two wheels) in the first column and the wheels (one wheel) in the second column can still form a triangular support structure to prevent the exhibition frame 1 from tilting, avoiding the phenomenon that the exhibition frame 1 loses balance due to the damage of the wheels, and improving the moving efficiency of the exhibition stand. Therefore, the preset balance position 19 is a support position for the exhibition stand to be in a force balance state and a support position for preventing the exhibition stand (exhibition frame 1) from tilting. The preset balance position 19 can be a position on a vertical symmetry plane of the exhibition frame 1 along the X direction or a position near the vertical symmetry plane of the exhibition frame 1 along the X direction, as long as the exhibition stand can be in a force balance state. In addition, if the exhibition stand is provided with a plurality of drive wheels 2, the drive wheels 2 can also be provided with corresponding preset balance positions 19, and when any drive wheel 2 is damaged, the remaining normal drive wheels 2 are moved to the corresponding preset balance positions 19. In addition, the preset balance position 19 can be provided with a plurality of positions, and the drive wheels 2 and / or the driven wheels 3 can be moved to the corresponding preset balance positions 19 according to actual needs.

[0031] In one embodiment, the moving device includes drive wheels 2 and / or driven wheels 3, and a plurality of first jacking mechanisms 4 are arranged between the drive wheels 2 and the exhibition frame 1 and / or between the driven wheels 3 and the exhibition frame 1 to adjust the distance between the exhibition frame 1 and the ground.

[0032] The exhibition stand of the present application also includes a first lifting mechanism 4, which is used to adjust the distance between the display frame 1 and the ground to ensure the overall passability of the display frame 1 and to adapt to the unevenness on the ground. Specifically, the mobile device includes a driving wheel 2 and / or a driven wheel 3, and the first lifting mechanism 4 is arranged between the corresponding driving wheel 2 and the display frame 1 and / or between the corresponding driven wheel 3 and the display frame 1. When the display frame is equipped with a driving wheel 2, the first lifting mechanism 4 is arranged between the corresponding driving wheel 2 and the display frame 1; when the display frame is equipped with a driven wheel 3, the first lifting mechanism 4 is arranged between the corresponding driven wheel 3 and the display frame 1; when the display frame is equipped with a driving wheel 2 and a driven wheel 3, the first lifting mechanism 4 is arranged between the corresponding driving wheel 2 and the display frame 1 and between the corresponding driven wheel 3 and the display frame 1. Preferably, the first lifting mechanism 4 is arranged between the corresponding driving wheel 2 and the display frame 1 and between the corresponding driven wheel 3 and the display frame 1 (the corresponding display frame is equipped with a driving wheel 2 and a driven wheel 3). Furthermore, a plurality of first lifting mechanisms 4 are provided, and the number of the first lifting mechanisms 4 is consistent with the total number of the driving wheels 2 and the driven wheels 3, such as Figure 1 and Figure 3 As shown, there is a driving wheel 2 and four driven wheels 3. Therefore, a total of five first jacking mechanisms 4 are provided, and each driving wheel 2 and driven wheel 3 is equipped with a first jacking mechanism 4. Furthermore, the top of the first jacking mechanism 4 is connected to the bottom of the display frame 1, and the bottom of the first jacking mechanism 4 is connected to the corresponding driving wheel 2 or driven wheel 3. Among them, the first jacking mechanism 4 can adopt a hydraulic cylinder and be equipped with a corresponding hydraulic pump 30, such as three hydraulic pumps 30 can be configured, including a front hydraulic pump 32, a middle hydraulic pump 33 and a rear hydraulic pump 34. The front hydraulic pump 32 controls the lifting and lowering of the driving wheel 2 at the front end of the display frame 1, the middle hydraulic pump 33 controls the lifting and lowering of the two driven wheels 3 in the middle of the display frame 1, and the rear hydraulic pump 34 controls the lifting and lowering of the two driven wheels 3 at the rear end of the display frame 1. Among them, the hydraulic pump 30 is connected to the display frame 1 through a hydraulic pump fixing plate 31. Furthermore, the hydraulic cylinder and the display frame 1 are connected by a welding plate 17, as shown Figure 2 、 Figure 4 and Figure 5As shown, a driving wheel fixing bracket 14 and a driven wheel fixing bracket 15 are provided at the bottom of the display frame 1. The hydraulic cylinder of the driving wheel 2 is connected to the driving wheel fixing bracket 14, and the hydraulic cylinder of the driven wheel 3 is connected to the driven wheel fixing bracket 15. The connection structure between the hydraulic cylinder of the driving wheel 2 and the driving wheel fixing bracket 14 is the same as the connection structure between the hydraulic cylinder of the driven wheel 3 and the driven wheel fixing bracket 15. Specifically, a heat sink 16 is provided on the top of the hydraulic cylinder, and the heat sink 16 is connected to the welding plate 17 by bolts 20 (five bolts), wherein four bolts 20 are located at the four corners of the rectangular welding plate 17 (connecting the four sides of the hydraulic cylinder to the four sides of the welding plate 17), and one bolt 20 is located at the middle position of the rectangular welding plate 17 (connecting the center of the hydraulic cylinder to the center of the welding plate 17). The five bolts 20 form a five-point fixed connection structure, as shown in FIG. Figure 6 As shown, this improves connection stability. This connection ensures full contact between the heat sink 16 and the weld plate 17, effectively dissipating heat and preventing overheating of the hydraulic cylinder during prolonged operation. Furthermore, the heat sink 16 maintains extensive contact with both the top of the hydraulic cylinder and the weld plate 17, creating a more robust structure that effectively resists impact forces from the wheels and provides a secure fixation, avoiding the breakage of the weld plate 17 that has been a problem in the past.

[0033] In one embodiment, the driven wheel 3 includes a universal wheel 5 and a one-way wheel 6 . The forward direction of the display frame 1 is a first direction. Along the first direction, the universal wheel 5 is arranged between the driving wheel 2 and the one-way wheel 6 .

[0034] The driven wheel 3 of the present application includes a universal wheel 5 and a one-way wheel 6, which cooperate with each other to not only improve the stability of the booth, but also improve the steering ability of the booth. Figure 1 and Figure 3As shown, there is a drive wheel 2, two universal wheels 5, and two one-way wheels 6. The first direction is the X direction, which is the length of the display frame 1 and the display equipment. Along the X direction (the forward direction of the display frame 1), the one-way wheel 6, the universal wheel 5, and the drive wheel 2 are arranged in sequence. During the normal movement of the booth, the universal wheel 5 and the one-way wheel 6 cooperate to improve the booth's travel stability. When the booth needs to turn, due to the narrow movement distance of the auto show hall, the universal wheel 5 can be used to improve turning ability. At this time, the first lifting mechanism 4 can be used to lift the drive wheel 2 and the two universal wheels 5, so that the two one-way wheels 6 are suspended off the ground. The staff can then manually push the rear end of the display frame 1 in the Y direction to use the universal wheels 5 to assist in steering, improving the booth's turning ability. After the turn is completed, the first lifting mechanism 4 can be restored to its state, allowing the drive wheel 2, universal wheels 5, and one-way wheels 6 to operate simultaneously. The center of gravity of the exhibition stand is located between the drive wheel 2 and the universal wheel 5 to ensure that the exhibition stand will not tip over toward the rear end of the display frame 1 when the one-way wheel 6 leaves the ground. The center of gravity of the exhibition equipment is located at the front end. When the automobile frame exhibition equipment is placed on the exhibition stand, the center of gravity of the entire exhibition stand with the exhibition equipment is located between the drive wheel 2 and the universal wheel 5 to improve travel stability.

[0035] In one embodiment, an electric traction component 7 is further included. The electric traction component 7 is detachably arranged on the display frame 1. A charging interface 26 is provided on the electric traction component 7. The charging interface 26 faces the front end of the display frame 1 under preset conditions.

[0036] The exhibition stand of the present application also includes an electric traction assembly 7, and the drive wheel 2 is provided on the electric traction assembly 7. The electric traction assembly 7 provides rotational power to the drive wheel 2 to realize the movement of the exhibition stand. Specifically, the electric traction assembly 7 is provided with a charging interface 26, and the electric traction assembly 7 is detachably provided at the bottom of the display frame 1. When the exhibition stand is powered during movement, the electric traction assembly 7 can be removed from the bottom of the display frame 1 and moved to a nearby location for charging. In addition, the initial installation position of the electric traction assembly 7 is that the charging interface 26 faces the front end of the display frame 1. The charging interface 26 faces the front end of the display frame 1 under preset conditions (the electric traction assembly 7 is provided at the front end of the display frame 1). For example, the preset condition is that the electric traction assembly 7 automatically turns back to the front end of the display frame 1 when the electric traction assembly 7 automatically turns back to the front end of the display frame 1 when the electric traction assembly 7 automatically turns back to the front end of the display frame 1 so that the power cord can be directly connected to the charging interface 26 for charging, thereby realizing quick charging. Therefore, the electric traction assembly 7 of the booth of the present application can be removed and moved to a power source for charging, or directly connected to the charging port 26 via a power cord to charge the electric traction assembly 7. The appropriate charging method is selected according to actual needs, thereby improving the convenience of use. In addition, the battery assembly of the electric traction assembly 7 can be detachably connected to the electric traction assembly 7. When charging is required, it is only necessary to remove the battery assembly and charge it with the corresponding charging equipment. Among them, the electric traction assembly 7 includes a drive wheel 2, and the electric traction assembly 7 can integrate a controller, battery, and roller (drive wheel 2) into one. The drive wheel 2 of the electric traction assembly 7 can achieve 360° flexible steering.

[0037] In one embodiment, a locking member is further included. A first connecting member is provided on the first lifting mechanism, and a second connecting member is provided on the electric traction assembly.

[0038] The locking member cooperates with the first connecting member at the bottom of the first lifting mechanism 4 and the second connecting member at the top of the electric traction assembly 7 to realize the detachability of the electric traction assembly 7. Specifically, the first connecting member is a connecting plate 21, which is arranged at the bottom of the first lifting mechanism 4, and the second connecting member is a U-shaped fixing plate 22, which is arranged at the top of the electric traction assembly 7. The top of the electric traction assembly 7 is connected to the connecting plate 21 through the U-shaped fixing plate 22. Figure 5As shown, a slot 23 is formed on the U-shaped fixing plate 22, the connecting plate 21 is inserted into the slot 23, and then the connecting plate 21 is connected to the slot 23 by a pin 24, wherein the plugging direction of the connecting plate 21 in the slot 23 is along the horizontal direction, and the plugging direction of the pin 24 is along the vertical direction, and the pin 24 adopts a tapered pin with a large top diameter and a small bottom diameter, and uses its own gravity to be inserted from top to bottom into the connecting plate 21 and the pin hole 25 on the U-shaped fixing plate to lock and fix the connecting plate 21 and the U-shaped fixing plate. When power feeding occurs during movement, the display frame 1 can be lifted by the second jacking mechanism 8 and the first support seat 9, so that the driving wheel 2 of the electric traction assembly 7 is suspended in the air, and then the pin 24 is removed, and the U-shaped fixing plate on the electric traction assembly 7 is removed from the connecting plate 21, so as to pull the electric traction assembly 7 to a nearby charging location; after charging is completed, the electric traction assembly 7 is pushed so that the connecting plate 21 is inserted into the U-shaped fixing plate on the electric traction assembly 7. After the electric traction assembly 7 is pushed into place, the pin holes 25 on the connecting plate 21 and the U-shaped fixing plate are aligned, and then the pin 24 is inserted into the pin holes 25 on the connecting plate 21 and the U-shaped fixing plate to lock and fix the connecting plate 21 and the U-shaped fixing plate. Finally, the state of the second jacking mechanism 8 and the first support seat 9 is restored to lower the display frame 1, and the booth can continue to work, thereby realizing the quick removal and charging of the electric traction assembly 7.

[0039] In one embodiment, it further includes a plurality of second lifting mechanisms 8 and a plurality of first support seats 9, wherein the plurality of first support seats 9 are all arranged at the bottom of the display frame 1, and the second lifting mechanisms 8 are arranged between the corresponding first support seats 9 and the display frame 1.

[0040] like Figure 7 As shown, the exhibition stand of the present application also includes a second lifting mechanism 8 and a first support base 9.

Specifically, the number of first support bases 9 is the same as the number of second lifting mechanisms 8, with one second lifting mechanism 8 corresponding to one first support base 9. The top end of the first lifting mechanism 4 is set at the bottom of the display frame 1, and the bottom end of the first lifting mechanism 4 is connected to the corresponding first support base 9. The first support base 9 is used to contact or separate from the ground. Furthermore, a total of eight first support bases 9 are set at the bottom of the display frame 1. The eight first support bases 9 are symmetrically arranged about the vertical symmetry plane of the display frame 1 along the X direction. That is, four first support bases 9 are set on each side of the display frame 1 along the X direction to provide stable support when the exhibition stand is parked for a long time. In addition, if any driving wheel 2 or any driven wheel 3 is damaged, the support function of the second lifting mechanism 8 and the first support base 9 can be used to suspend the wheel for replacement or repair.

[0041] In one embodiment, a camera assembly 10 is provided on the display frame 1 , and the camera range of the camera assembly 10 includes the working range of the driving wheel 2 , the driven wheel 3 , the first lifting mechanism 4 and the second lifting mechanism 8 .

Specifically, the camera assembly 10 is provided in the front and rear areas of the bottom of the display frame 1, and the image is displayed through the corresponding display screen, such as displaying the image on the display screen of the remote control assembly. When the remote control assembly is powered on, the image of the camera assembly 10 is automatically enabled, and the steering and rolling of the electric traction assembly 7, the universal wheel 5, and the driven wheel 3 can be clearly seen through the image. In addition, the lifting and lowering of the first jacking mechanism 4 and the second jacking mechanism 8 and the distance to the obstacles can also be seen, so as to guide the staff to control the movement of the exhibition stand.

[0043] In one embodiment, a plurality of distance sensors 11 are provided around the display frame 1 , and a first-level alarm triggering unit and / or a second-level alarm triggering unit are constructed by data collected by the plurality of distance sensors 11 .
