Description

Technical Field

[0001] This utility model relates to the field of vehicle logo technology, specifically to a logo switching device and a car. Background Technology

[0002] In modern society, signage, as an important tool for information display and identification, is widely used in various fields, such as commercial advertising, traffic signs, and vehicle logos. Different application scenarios place diverse demands on the display methods and functions of signage. For example, retractable car logos, as a feature that enhances the luxury, technological feel, and brand recognition of a vehicle, are commonly found on some higher-end models.

[0003] To achieve diversified signage displays, some existing technologies attempt to use multiple independent drive units to control the movement of different types of signs separately. However, vehicle logos are generally placed in the engine compartment and front grille area. Using multiple independent drive units results in structural complexity, large space occupation, high cost, and a higher failure rate. Multiple drive units not only increase the size and weight of the equipment but also require a complex control system to coordinate the operation of each unit, leading to reduced system reliability and increased maintenance costs. In addition, some solutions attempting linked designs also suffer from poor linkage effects and unsmooth switching processes, failing to achieve a natural transition between upright and flat sign displays, thus affecting the overall display effect. Utility Model Content

[0004] The purpose of this utility model is to provide a sign switching device and automobile that is compact in structure, can realize multi-functional display, reduce costs, and improve the reliability of switching display.

[0005] A sign switching device, comprising: Support base; The lifting mechanism includes a drive assembly, a lifting transmission assembly, and a lifting bracket. The drive assembly is used to drive the lifting transmission assembly to move so as to lift the lifting bracket, thereby causing the upright member installed on the lifting bracket to extend or retract into the support base. The flipping mechanism includes a linkage assembly and a connecting rod. One end of the connecting rod is connected to the lifting bracket, and the other end is connected to the linkage assembly. The linkage assembly is connected to a flippable flat marker, so that when the lifting bracket is raised or lowered, the connecting rod drives the linkage assembly to move, thereby causing the flat marker to flip back and forth.

[0006] In the above scheme, when the sign holder needs to extend from its support base, the drive component drives the lifting transmission component to move, causing the lifting bracket to move upward. As the lifting bracket rises, the sign holder also extends from its support base, thus displaying the sign at a specific position. When the sign holder needs to retract from its support base, the drive component drives the lifting transmission component to move the lifting bracket downward. During this process, the lifting bracket can drive the linkage component to move through the connecting rod, thereby causing the flat sign holder to flip towards the sign holder. In this way, the flat sign holder replaces the sign holder for display, realizing a multi-functional display of the car logo. The structure is compact and has a high space utilization rate. The various components of the lifting mechanism and the flipping mechanism are closely connected to each other, which can ensure stability and reliability during the movement. This linkage design reduces additional drive equipment and control links, reduces costs and the probability of failure, and makes the sign switching process smoother and more natural, enhancing the display effect.

[0007] Furthermore, the linkage assembly includes a first linkage, a second linkage, and a transmission bracket. One end of the first linkage is connected to one end of the connecting rod, and the other end is connected to one end of the second linkage. The other end of the second linkage is connected to the transmission bracket. The transmission bracket is connected to a flat marker bracket, and the flat marker is disposed on the flat marker bracket.

[0008] In the above scheme, assuming the signpost is initially displayed with its support extended, as the lifting bracket descends, it lowers one end of the connecting rod, causing the first link to swing, which in turn causes the second link to swing. The second link then causes the transmission bracket to oscillate, and the movement of the transmission bracket causes the flat sign bracket and the flat sign to flip towards the signpost. When the signpost is fully retracted into the support, the flat sign flips into place and replaces the signpost for display. Two different actions are completed under the action of a single drive source, achieving multi-functional display of the sign while reducing costs. The links are connected by hinges, etc., occupying little space. Complex motion conversions are achieved within a limited space. The signpost can retract into the support, and the flipping of the flat sign does not occupy too much extra space, improving space utilization. It is especially suitable for applications with high space requirements, such as the front of a car.

[0009] Furthermore, the transmission bracket includes two transmission rods, one end of which is connected to a transmission shaft, and the other end of which is hinged to the flat bracket. The transmission shaft is mounted on the support base, and one end of the second connecting rod is connected to the middle of one of the transmission rods.

[0010] In the above scheme, since one end of the second link is connected to the middle of one of the transmission rods, the movement of the second link will cause the transmission rod to rotate around the transmission shaft. Since the two transmission rods are connected as a whole through the transmission shaft, the other transmission rod will also rotate synchronously. Since the other ends of the two transmission rods are hinged to the flat marker bracket, the rotation of the transmission rods will drive the flat marker bracket to flip in the direction away from or towards the upright marker, realizing the switching display of the flat marker and the upright marker. This structural design is compact, and the various components are closely connected. It realizes complex motion conversion in a limited space, reduces the overall volume of the device, and improves the space utilization rate. It is especially suitable for application scenarios with high space requirements.

[0011] Furthermore, the flat support includes an integrally formed panel and connecting plates located on both sides of the panel. The end of the connecting plate is provided with a connecting column, and the support base is provided with a track groove on the moving trajectory of the connecting column. The connecting column is movably connected to the track groove.

[0012] In the above scheme, when the lifting bracket rises or falls, the connecting rod rises or falls under its drive, thereby causing the first connecting rod to swing. The first connecting rod drives the second connecting rod to move, causing the transmission bracket to drive the flat marker bracket and flat marker to flip. During the flipping process, the connecting columns at the ends of the connecting plates on both sides of the flat marker bracket move along a specific trajectory in the track groove of the support seat, which can effectively limit the movement direction and range of the flat marker, avoid swaying or deviation, and ensure the stability and accuracy of the flat marker's movement, making the switching process between the upright marker and the flat marker more smooth and natural.

[0013] Furthermore, the lifting transmission assembly includes a first movable rod, a second movable rod, and a connecting bracket. The first movable rod is connected to the drive assembly. One end of the second movable rod is movably connected to the first movable rod, and the other end is movably connected to one end of the connecting bracket. The connecting bracket is connected to the lifting bracket.

[0014] In the above scheme, the first movable rod is driven by the drive component, which in turn drives the second movable rod, thereby driving the connecting bracket to move. Since the connecting bracket is connected to the lifting bracket, the connecting bracket will drive the lifting bracket to rise or fall, causing the upright member to extend or retract from the support seat. The various movable parts of this structure can be adjusted in angle and position according to the actual installation space and layout requirements, and can adapt to the internal space of support seats of different shapes and sizes. This flexibility allows the device to be applied to a variety of different scenarios, improving the versatility and applicability of the device.

[0015] Furthermore, the support base is provided with several guide rods, and the lifting bracket includes a main body and stepped parts located on both sides of the main body. The stepped parts are movably sleeved on the guide rods, and one of the stepped parts is connected to the connecting rod.

[0016] In the above scheme, when the drive component is started and drives the lifting transmission component to move, the connecting bracket in the lifting transmission component drives the lifting bracket connected to it to move. Since several guide rods are set on the support base, and the stepped parts on both sides of the main body of the lifting bracket are movably sleeved on the guide rods, the guide rods provide a clear path for the movement of the lifting bracket. When the connecting bracket drives the lifting bracket to rise or fall, the stepped parts move in a straight line along the guide rods, ensuring that the lifting bracket can only move in the direction limited by the guide rods. This allows the signpost installed on the main body of the lifting bracket to stably and accurately extend or retract from the support base, improving the stability and reliability of the signpost display.

[0017] Furthermore, the drive assembly includes a drive member, a worm, a worm wheel, a drive gear, and a driven gear. The output end of the drive member is connected to the worm, the worm meshes with the worm wheel, the worm wheel is driven by the drive gear, the drive gear meshes with the driven gear, and the driven gear is connected to the first movable rod.

[0018] In the above scheme, the worm gear and worm wheel transmission has a large transmission ratio, which can achieve a large deceleration effect in a small space, converting the high-speed rotation of the driving component into a low-speed rotation suitable for system operation, while significantly increasing the torque. The worm, worm wheel, driving gear, and driven gear all have high transmission accuracy and stability. During the movement, the meshing between the various transmission components is tight, which can accurately transmit power, reduce vibration and impact during the movement, and ensure the smoothness and accuracy of the movement of the upright and flat markers. At the same time, this transmission method has high reliability and can maintain stable working performance during long-term use, reducing the probability of failure.

[0019] Furthermore, the lifting mechanism also includes a push rod and a buckle. The main body is provided with a groove, and an elastic element is embedded in the groove. The T-shaped push rod is pressed on the elastic element and its tail passes through the main body and abuts against the buckle. The buckle is movably engaged with the connecting bracket.

[0020] In the above scheme, when the flag stand is subjected to impact, it will sway or move downward. This abnormal movement will pry the push rod downward. The push rod overcomes the elastic force of the elastic element and moves downward. The downward movement of the push rod pushes the buckle to flip, causing the buckle to disengage from the movable engagement state with the connecting bracket. Once the buckle disengages from the connecting bracket, the lifting bracket loses its original support and constraint and falls downward under its own weight. As the lifting bracket descends, the flag stand also descends. At the same time, the connecting rod assembly drives the flat flag to flip, entering the process of the flag stand descending and the flat flag flipping to close, realizing the collapse function. This collapse action can protect the flag stand and the entire device from greater damage to a certain extent. At the same time, the downward movement of the flag stand and the closed state of the flat flag also increases the anti-theft capability of the device, because it becomes more difficult to illegally obtain the flag stand.

[0021] Furthermore, the buckle is L-shaped, with its bent portion being cylindrical. The buckle is rotatably connected to the lifting bracket through the bent portion. One end of the buckle is provided with a protruding structure, and the connecting bracket is provided with a connecting hole. The protruding structure is movably engaged with the connecting hole.

[0022] In the above scheme, under normal working conditions, the protruding structure of the buckle and the movable engagement of the connecting hole can effectively transmit the power of the connecting bracket to the lifting bracket, ensuring the stability and accuracy of the lifting and lowering of the sign-erecting component and the flipping of the flat sign-erecting component. When the sign-erecting component is subjected to impact force, it will sway or move downward, thereby prying the push rod to move down. The force of the push rod moving down acts on the buckle, causing the buckle to rotate around its bent part. As the buckle rotates, the protruding structure at one end gradually disengages from the connecting hole of the connecting bracket. Once the protruding structure is completely disengaged from the connecting hole, the connection between the buckle and the connecting bracket is broken, and the lifting bracket loses the support and constraint from the connecting bracket. Therefore, it begins to fall under its own weight, and the sign-erecting component descends accordingly, while simultaneously driving the flat sign-erecting component to flip and close, activating the collapse and anti-theft functions.

[0023] An automobile includes a sign switching device as described in any of the above embodiments.

[0024] This utility model discloses a sign switching device and a vehicle, which features a compact structure, multi-functional display capabilities, reduced costs, and improved reliability of the switching display. When the sign holder needs to extend from its support base, the drive component drives the lifting transmission component to move, causing the lifting bracket to move upward. As the lifting bracket rises, the sign holder also extends from its support base, thus displaying the sign at a specific position. When the sign holder needs to retract from its support base, the drive component drives the lifting transmission component to move the lifting bracket downward. During this process, the lifting bracket, through a connecting rod, drives the linkage component to move, causing the flat sign holder to flip towards the sign holder. In this way, the flat sign holder replaces the sign holder for display, achieving multi-functional display of the vehicle logo. The structure is compact with high space utilization. The various components of the lifting and flipping mechanisms are tightly connected, ensuring stability and reliability during movement. This linkage design reduces additional drive equipment and control links, lowering costs and the probability of failure. Moreover, it makes the sign switching process smoother and more natural, enhancing the display effect. Attached Figure Description

[0033] The following will describe in further detail a sign switching device and a car according to the present invention, with reference to specific embodiments and accompanying drawings.

[0034] like Figures 1 to 3 As shown in a preferred embodiment, a sign switching device of the present invention includes a support base 3, a lifting mechanism 4, and a flipping mechanism 5. The lifting mechanism 4 includes a drive assembly 41, a lifting transmission assembly 42, and a lifting bracket 43. The drive assembly 41 is used to drive the lifting transmission assembly 42 to move and drive the lifting bracket 43 to rise and fall, thereby causing the upright sign 1 installed on the lifting bracket 43 to extend or retract into the support base 3. The flipping mechanism 5 includes a connecting rod assembly 51 and a connecting rod 52. One end of the connecting rod 52 is connected to the lifting bracket 43, and the other end is connected to the connecting rod assembly 51. The connecting rod assembly 51 is connected to a flippable flat sign 2, so that when the lifting bracket 43 rises and falls, the connecting rod 52 drives the connecting rod assembly 51 to move, thereby causing the flat sign 2 to flip back and forth.

[0035] In the above embodiment, when the signpost 1 needs to extend out of the support base 3, the drive component 41 drives the lifting transmission component 42 to move, which in turn drives the lifting bracket 43 to move upward. As the lifting bracket 43 rises, the signpost 1 also extends out of the support base 3. At this time, the flat signpost 2 is hidden inside the support base 3 under the action of the flipping mechanism 5, thereby displaying the signpost 1 at a specific position. When the signpost 1 needs to retract into the support base 3, the drive component 41 drives the lifting transmission component 42 to drive the lifting bracket 43 to move downward. During this process, the lifting bracket 43 can drive the connecting rod component 51 to move through the connecting rod 52, thereby causing the flat signpost 2 to flip in the direction of the signpost 1. In this way, the flat signpost 2 replaces the signpost 1 for display.

[0036] This device integrates the extension and retraction of the upright sign 1 and the flipping function of the flat sign 2, enabling the switching of multiple sign display modes and realizing the multi-functional display of vehicle logos. It has a compact structure and high space utilization. The various components of the lifting mechanism 4 and the flipping mechanism 5 are closely connected to each other, which can ensure stability and reliability during the movement process. This linkage design reduces additional drive equipment and control links, reduces costs and the probability of failure, and makes the sign switching process smoother and more natural, enhancing the display effect.

[0037] In this embodiment, the support base 3 includes a front support cover 301 and a rear support cover 302. The lifting mechanism 4 and the flipping mechanism 5 are both located in the cavity assembled with the front support cover 301 and the rear support cover 302. An upper cover is installed on the rear support cover 302 to isolate the flat cover 2 from other components inside the front cover to a certain extent.

[0038] like Figure 3 and Figure 4 As shown, in some embodiments, the linkage assembly 51 includes a first linkage 511, a second linkage 512, and a transmission bracket 513. One end of the first linkage 511 is connected to one end of the connecting rod 52, and the other end is connected to one end of the second linkage 512. The other end of the second linkage 512 is connected to the transmission bracket 513. The transmission bracket 513 is connected to a flat marker bracket 514, and the flat marker 2 is disposed on the flat marker bracket 514. Assuming the initial state is that the signpost 1 is extended from the support base 3, during the descent of the lifting bracket 43, the lifting bracket 43 will drive one end of the connecting rod 52 to descend, causing the first connecting rod 511 to swing, which in turn causes the second connecting rod 512 to swing. The second connecting rod 512 will cause the transmission bracket 513 to sway. The movement of the transmission bracket 513 will cause the flat sign bracket 514 and the flat sign 2 to flip towards the signpost 1. When the signpost 1 is completely retracted into the support base 3, the flat sign 2 flips into place and replaces the signpost 1 for display. Two different actions are completed under the action of a single driving source, realizing the multi-functional display of the sign and reducing costs. The connecting rods are connected by hinges, etc., occupying little space. Complex motion conversion is achieved in a limited space. The signpost 1 can be retracted into the support base 3, and the flipping of the flat sign 2 will not occupy too much extra space, improving space utilization. It is especially suitable for applications with high space requirements, such as the front of a car.

[0039] like Figure 3 and Figure 5As shown, in some embodiments, the transmission bracket 513 includes two transmission rods 5131, with a transmission shaft 5132 connected between one end of the two transmission rods 5131 and the other end of the shaft is hinged to the flat bracket 514. The transmission shaft 5132 is mounted on the support base 3, and one end of the second connecting rod 512 is connected to the middle of one of the transmission rods 5131. Since one end of the second link 512 is connected to the middle of one of the transmission rods 5131, the movement of the second link 512 will cause the transmission rod 5131 to rotate around the transmission shaft 5132. Since the two transmission rods 5131 are connected as a whole through the transmission shaft 5132, the other transmission rod 5131 will also rotate synchronously. Since the other ends of the two transmission rods 5131 are hinged to the flat marker bracket 514, the rotation of the transmission rod 5131 will drive the flat marker bracket 514 to flip in the direction away from or towards the upright marker 1, realizing the switching display of the flat marker 2 and the upright marker 1. This structural design is compact, and the various components are closely connected. It realizes complex motion conversion in a limited space, reduces the overall volume of the device, and improves the space utilization rate. It is especially suitable for application scenarios with high space requirements.

[0040] like Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the flat marker bracket 514 includes an integrally formed panel 5141 and connecting plates 5142 located on both sides of the panel 5141. The ends of the connecting plates 5142 are provided with connecting posts 5143. The support base 3 is provided with a track groove 311 on the movement trajectory of the connecting posts 5143. The connecting posts 5143 are movably connected to the track groove 311. When the lifting bracket 43 rises or falls, the connecting rod 52 rises or falls under its drive, thereby driving the first connecting rod 511 to swing. The first connecting rod 511 drives the second connecting rod 512 to move, so that the transmission bracket 513 drives the flat marker bracket 514 and the flat marker 2 to flip. During the flipping process, the connecting posts 5143 at the ends of the connecting plates 5142 on both sides of the flat marker bracket 514 move along a specific trajectory in the track groove 311 of the support base 3, which can effectively limit the movement direction and range of the flat marker 2, avoid swaying or deviation, and ensure the stability and accuracy of the movement of the flat marker 2, making the switching process of the upright marker 1 and the flat marker 2 smoother and more natural.

[0041] like Figure 3 and Figure 4As shown, in some embodiments, the lifting transmission assembly 42 includes a first movable rod 421, a second movable rod 422, and a connecting bracket 423. The first movable rod 421 is connected to the drive assembly 41. One end of the second movable rod 422 is movably connected to the first movable rod 421, and the other end is movably connected to one end of the connecting bracket 423. The connecting bracket 423 is connected to the lifting bracket 43. By driving the first movable rod 421 to move through the drive assembly 41, the second movable rod 422 can be driven to move, thereby driving the connecting bracket 423 to move. Since the connecting bracket 423 is connected to the lifting bracket 43, the connecting bracket 423 will drive the lifting bracket 43 to rise or fall, causing the upright member 1 to extend or retract from the support base 3. The various movable parts of this structure can be adjusted in angle and position according to the actual installation space and layout requirements, and can adapt to the internal space of the support base 3 of different shapes and sizes. This flexibility allows the device to be applied to a variety of different scenarios, improving the versatility and applicability of the device.

[0042] In this embodiment, in addition to the structure of the first movable rod 421 and the second movable rod 422, the lifting transmission assembly 42 can also use existing linear lifting assemblies such as lead screw and nut assemblies to realize the lifting movement of the connecting bracket 423.

[0043] like Figure 4 and Figure 6 As shown, in some embodiments, the support base 3 is provided with several guide rods 6, and the lifting bracket 43 includes a main body 431 and stepped portions 432 located on both sides of the main body 431. The stepped portions 432 are movably sleeved on the guide rods 6, and one of the stepped portions 432 is connected to the connecting rod 52. When the drive assembly 41 is started and drives the lifting transmission assembly 42 to move, the connecting bracket 423 in the lifting transmission assembly 42 drives the lifting bracket 43 connected to it to move. Since the support base 3 is provided with several guide rods 6, and the stepped portions 432 on both sides of the main body 431 of the lifting bracket 43 are movably sleeved on the guide rods 6, the guide rods 6 provide a clear path for the movement of the lifting bracket 43. When the connecting bracket 423 drives the lifting bracket 43 to rise or fall, the stepped portions 432 move in a straight line along the guide rods 6, ensuring that the lifting bracket 43 can only move in the direction defined by the guide rods 6. This allows the sign 1 installed on the main body 431 of the lifting bracket 43 to stably and accurately extend or retract from the support base 3, improving the stability and reliability of the sign display.

[0044] like Figure 6 and Figure 7As shown, in some embodiments, the drive assembly 41 includes a drive member 411, a worm 412, a worm wheel 413, a drive gear 414, and a driven gear 415. The output end of the drive member 411 is connected to the worm 412. The worm 412 is meshed with the worm wheel 413. The worm wheel 413 is driven by the drive gear 414. The drive gear 414 is meshed with the driven gear 415. The driven gear 415 is connected to the first movable rod 421. The worm gear 412 and worm wheel 413 transmission has a large transmission ratio, which can achieve a large reduction effect in a small space, converting the high-speed rotation of the driving component 411 into a low-speed rotation suitable for system operation, while significantly increasing the torque. The worm gear 412, worm wheel 413, driving gear 414 and driven gear 415 all have high transmission accuracy and stability. During the movement, the meshing between the various transmission components is tight, which can accurately transmit power, reduce vibration and impact during the movement, and ensure the smoothness and accuracy of the movement of the upright component 1 and the flat component 2. At the same time, this transmission method has high reliability and can maintain stable working performance during long-term use, reducing the probability of failure.

[0045] In this embodiment, the drive assembly 41 also includes a front cover 416 and a rear cover 417. The front cover 416 and the rear cover 417 are mounted on the support base 3. The drive component 411, the worm gear 412, the worm wheel 413, the drive gear 414, and the driven gear 415 are all installed in the cavity formed by the front cover 416 and the rear cover 417, forming a complete reducer.

[0046] like Figure 6 and Figure 7 As shown, in some embodiments, the lifting mechanism 4 further includes a push rod 44 and a buckle 45. The main body 431 is provided with a groove, and an elastic member 46 is embedded in the groove. The T-shaped push rod 44 is pressed on the elastic member 46 and its tail passes through the main body 431 and abuts against the buckle 45. The buckle 45 is movably engaged with the connecting bracket 423. When the marker 1 is subjected to an impact, it will sway or move downward. This abnormal movement will pry the push rod 44 downward. The push rod 44 moves downward against the elastic force of the elastic element 46. The downward movement of the push rod 44 pushes the buckle 45 to flip, so that the buckle 45 is disengaged from the active engagement state with the connecting bracket 423. Once the buckle 45 is disengaged from the connecting bracket 423, the lifting bracket 43 loses its original support and constraint and falls downward under its own weight. As the lifting bracket 43 descends, the marker 1 also descends. At the same time, the connecting rod assembly 51 drives the flat marker 2 to flip, entering the process of the marker 1 descending and the flat marker flipping to close, realizing the collapse function. This collapse action can protect the marker 1 and the entire device from greater damage to a certain extent. At the same time, the state of the marker 1 descending and the flat marker 2 closing also increases the anti-theft of the device, because it becomes more difficult to illegally obtain the marker 1.

[0047] like Figure 7 As shown, in some embodiments, the buckle 45 is L-shaped, and its bend 451 is cylindrical. The buckle 45 is rotatably connected to the lifting bracket 43 through the bend 451. One end of the buckle 45 is provided with a protrusion structure 452, and the connecting bracket 423 is provided with a connecting hole 4231. The protrusion structure 452 is movably engaged with the connecting hole 4231. Under normal operating conditions, the movable engagement between the protruding structure 452 of the buckle 45 and the connecting hole 4231 effectively transmits the power of the connecting bracket 423 to the lifting bracket 43, ensuring the stability and accuracy of the lifting and lowering of the sign 1 and the flipping of the flat sign 2. When the sign 1 is subjected to an impact force, the sign 1 sways or moves downward, thereby causing the push rod 44 to move downward. The force of the push rod 44 moving downward acts on the buckle 45, causing the buckle 45 to rotate around its bend 451. As the buckle 45 rotates, the protruding structure 452 at one end gradually disengages from the connecting hole 4231 of the connecting bracket 423. Once the protruding structure 452 is completely disengaged from the connecting hole 4231, the connection between the buckle 45 and the connecting bracket 423 is broken. The lifting bracket 43 loses the support and constraint from the connecting bracket 423 and begins to fall under its own weight. The sign 1 descends accordingly, simultaneously causing the flat sign 2 to flip and close, activating the collapse and anti-theft functions.

[0048] An automobile includes a sign switching device as described in any of the above embodiments.

[0049] This utility model discloses a sign switching device and the working principle and process of a car. When the sign 1 needs to extend out of the support base 3, the drive component 41 of the lifting mechanism 4 starts to work. The drive component 41 provides power to drive the lifting transmission component 42 to move. The lifting transmission component 42 converts and transmits the power of the drive component 41, driving the lifting bracket 43 to move upward. Since the sign 1 is installed on the lifting bracket 43, as the lifting bracket 43 rises, the sign 1 also extends out of the support base 3, thus displaying the sign at a specific position. Conversely, when the sign 1 needs to retract into the support base 3, the drive component 41 moves in the opposite direction, driving the lifting transmission component 42 to drive the lifting bracket 43 to move downward. The sign 1 then retracts into the support base 3 along with the lifting bracket 43, realizing the function of hiding the sign 1. During the lifting and lowering movement of the lifting bracket 43, the flipping mechanism 5 plays a role. One end of the connecting rod 52 is connected to the lifting bracket 43, and the other end is connected to the connecting rod assembly 51. When the lifting bracket 43 rises, the connecting rod 52 moves upward with the lifting bracket 43, thereby pushing the connecting rod assembly 51 to move. The connecting rod assembly 51 is connected to the flippable flat sign 2. The movement of the connecting rod assembly 51 causes the flat sign 2 to flip, switching it from the display state to the hidden state. When the lifting bracket 43 descends, the connecting rod 52 descends with it, pulling the connecting rod assembly 51 to move in the opposite direction, thereby causing the flat sign 2 to flip in the opposite direction, switching it from the hidden state to the display state. In this way, the back-and-forth flipping of the flat sign 2 is realized, which, in conjunction with the extension and retraction of the upright sign 1, completes the switching display of the sign.
