Description

Technical Field

[0001] This utility model pertains to mobile leisure sports equipment, specifically involving a rotating mechanism, a vehicle-mounted folding bracket and folding basketball hoop, and an advertising device. Background Technology

[0002] Basketball, as a highly popular sport, is enjoyed by people of all ages. Traditional fixed basketball hoops are usually installed in fixed locations such as courts or courtyards, and their location cannot be moved, limiting their use. In order to meet people's needs for playing basketball in different locations, especially the need for convenient use when traveling by car (such as RV travel, camping, and outdoor activities), vehicle-mounted basketball hoops have emerged.

[0003] Current vehicle-mounted basketball hoops typically use brackets mounted on the roof (e.g., roof rack) or rear (e.g., tow hook) to secure the basketball hoop to the vehicle. However, existing vehicle-mounted basketball hoops generally suffer from the following problems and shortcomings:

[0004] Difficulty in adjusting direction: The direction in which vehicles are parked is often limited by site conditions. Once existing vehicle-mounted basketball hoops are installed and fixed, the orientation of the backboard is tied to the vehicle's direction, meaning the backboard corresponds to the rear of the vehicle. This makes it difficult to flexibly adjust the backboard's direction according to the actual site conditions and wind direction, resulting in inconvenience in use.

[0005] Currently, most outdoor advertising is fixed, with a relatively limited display range. Mobile vehicle advertising is limited by the vehicle's height and is easily obstructed by traffic, resulting in limited visibility and low reach. Utility Model Content

[0071] This utility model embodiment provides a rotating mechanism, such as Figure 1-8 As shown, it includes a rotating base 101, a rotating upper seat 102, and a rotating assembly 103;

[0072] The rotating base 101 is used to fix it in the installation position;

[0073] The rotating upper seat 102 is configured above the rotating base 101 and is used to rotate relative to the rotating base 101.

[0074] The rotating assembly 103 is disposed between the rotating upper seat 102 and the rotating base 101, and is used to support the load of the rotating upper seat 102 and achieve low-friction rotation.

[0075] This utility model provides a fixed platform through a rotating base 101, and the rotating upper seat 102 is rotated through a rotating component 103 to meet the needs of different orientations.

[0076] In some embodiments, the rotating assembly 103 includes a rotating bearing assembly 1031, the rotating bearing assembly 1031 being disposed at the center of the rotating base 101, and the rotating upper seat 102 being disposed above the rotating base 101 and cooperating with the rotating bearing assembly 1031.

[0077] Furthermore, it also includes a rotary positioning pin 104. The rotary base 101 is provided with a plurality of first positioning holes spaced apart along the circumference, and the rotary upper seat 102 is provided with a second positioning hole at the corresponding position. The rotary positioning pin 104 is movably disposed through the second positioning hole and any one of the first positioning holes.

[0078] In the fixed state, the rotating positioning pin 104 is inserted into the second positioning hole and the first positioning hole on the rotating base 101 corresponding to the initial position of the rotating upper seat 102, so that the rotating upper seat 102 is fixed on the rotating base 101 and cannot rotate.

[0079] In the rotating state, remove the rotating positioning pin 104, manually rotate the upper rotating seat 102 to a suitable position, and then insert the rotating positioning pin 104 into the second positioning hole and the first positioning hole on the rotating base 101 corresponding to the suitable position. At this time, it returns to the fixed state, so that the upper rotating seat 102 is fixed on the rotating base 101 and cannot rotate.

[0080] It should be noted that the so-called suitable position refers to placing some functional components, such as a folding basketball hoop, on the rotating upper seat 102, so that these functional components are rotated to a position that can be used or that the user needs, which is the suitable position.

[0081] The rotary bearing assembly 1031 includes a rotary bearing outer ring 10311, a first rotary bearing inner ring 10312, and a first rotary bearing bracket 10313. The rotary bearing outer ring 10311 is connected to the rotating upper seat 102, and the first rotary bearing inner ring 10312 is connected to the rotating base 101. The rotary bearing outer ring 10311 is sleeved on the outer circumference of the first rotary bearing inner ring 10312, and the first rotary bearing bracket 10313 is provided between the two.

[0082] Specifically, the center of the rotating base 101 is provided with a first receiving groove 1011 for accommodating the rotating bearing assembly 1031, and the center of the bottom of the rotating upper seat 102 is provided with a second receiving groove 1021 for accommodating the rotating bearing assembly 1031; after the rotating base 101 and the rotating upper seat 102 are properly arranged, the first receiving groove 1011 and the second receiving groove 1021 together form a cavity for accommodating the rotating bearing assembly 1031.

[0083] Due to the cooperation between the rotating base 101 and the rotating upper seat 102, in reality, a part of the rotating bearing assembly 1031 is located in the first receiving groove 1011 and the other part is located in the second receiving groove 1021; that is, the outer ring 10311 of the slewing bearing is located in the first receiving groove 1011 and the inner ring 10312 of the first slewing bearing is located in the second receiving groove 1021.

[0084] The outer ring 10311 of the slewing bearing is fixedly connected to the rotating base 101, and the inner ring 10312 of the first slewing bearing is connected to the rotating upper seat 102 for rotation.

[0085] Alternatively, it can be said that the first receiving groove 1011 and the second receiving groove 1021 together form a cavity for receiving the rotary bearing assembly 1031, which is then placed inside the cavity.

[0086] Furthermore, the bottom of the rotating upper seat 102 is also provided with a third receiving groove 1023 for accommodating the sealing ring 1022.

[0087] The sealing ring 1022 prevents dust and other contaminants from entering the rotating parts of the rotating upper seat 102 and the rotating base 101, which could affect the smoothness of rotation over a long period of time.

[0088] In other embodiments, the rotating assembly 103 includes a ring gear bearing assembly 1032 and a first driving member 1033; the ring gear bearing assembly 1032 is disposed at the center of the rotating base 101, and the rotating upper seat 102 is disposed above the rotating base 101 and cooperates with the rotating bearing assembly 1031; the first driving member 1033 is disposed on the top surface of the rotating upper seat 102 and its output end passes through the rotating upper seat 102 and meshes with the ring gear bearing assembly 1032.

[0089] Specifically, the ring gear bearing assembly 1032 includes a ring gear 10321, a second slewing bearing inner ring 10322, and a second slewing bearing bracket 10323. The ring gear 10321 is connected to the rotating upper seat 102, and the second slewing bearing inner ring 10322 is connected to the rotating base 101. The ring gear 10321 is sleeved on the outer circumference of the second slewing bearing inner ring 10322, and the second slewing bearing bracket 10323 is provided between the two.

[0090] In this embodiment, a first receiving groove 1011 is provided at the center of the rotating base 101 for accommodating the ring gear bearing assembly 1032.

[0091] The ring gear bearing assembly 1032 meshes with the gear at the output end of the first drive member 1033 (the ring gear 10321 meshes with the gear at the output end of the first drive member 1033), and the clockwise or counterclockwise rotation of the first drive member 1033 drives the rotating upper seat 102 to rotate clockwise or counterclockwise.

[0092] For example, the first driving component 1033 is a worm gear reducer or a harmonic reducer.

[0093] Due to the self-locking function of the worm gear reducer, the rotating upper seat 102 will not rotate when the first drive component 1033 is closed.

[0094] In some other embodiments, the rotating assembly 103 includes a rotating bearing assembly 1031, a rotating gear disk 1034, and a second drive member 1035. The rotating bearing assembly 1031 is disposed at the center of the rotating base 101, and the rotating upper seat 102 is disposed above the rotating base 101 and cooperates with the rotating bearing assembly 1031. The rotating gear disk 1034 is disposed on the rotating base 101. The second drive member 1035 is disposed on the top surface of the rotating upper seat 102 and its output end passes through the rotating upper seat 102 and meshes with the rotating gear disk 1034.

[0095] Specifically, the rotary bearing assembly 1031 includes a rotary bearing outer ring 10311, a first rotary bearing inner ring 10312, and a first rotary bearing bracket 10313. The rotary bearing outer ring 10311 is connected to the rotating upper seat 102, the first rotary bearing inner ring 10312 is connected to the rotating base 101, the rotary bearing outer ring 10311 is sleeved on the outer circumference of the first rotary bearing inner ring 10312, and the first rotary bearing bracket 10313 is provided between the two.

[0096] The center of the rotating base 101 is provided with a first receiving groove 1011 for accommodating the rotating bearing assembly 1031, and the center of the bottom of the rotating upper seat 102 is provided with a second receiving groove 1021 for accommodating the rotating bearing assembly 1031; after the rotating base 101 and the rotating upper seat 102 are properly arranged, the first receiving groove 1011 and the second receiving groove 1021 together form a cavity for accommodating the rotating bearing assembly 1031.

[0097] Due to the cooperation between the rotating base 101 and the rotating upper seat 102, in reality, a part of the rotating bearing assembly 1031 is located in the first receiving groove 1011 and the other part is located in the second receiving groove 1021; that is, the outer ring 10311 of the slewing bearing is located in the first receiving groove 1011 and the inner ring 10312 of the first slewing bearing is located in the second receiving groove 1021.

[0098] The outer ring 10311 of the slewing bearing is fixedly connected to the rotating base 101, and the inner ring 10312 of the first slewing bearing is connected to the rotating upper seat 102 for rotation.

[0099] Alternatively, it can be said that the first receiving groove 1011 and the second receiving groove 1021 together form a cavity for receiving the rotary bearing assembly 1031, which is then placed inside the cavity.

[0100] The first receiving groove 1011 is also used to receive a rotating gear disk 1034, which is sleeved on the outer ring of the slewing bearing outer ring 10311 and there is no connection between the two.

[0101] The rotating gear disk 1034 is an external gear disk. The outer side of the rotating gear disk 1034 meshes with the gear at the output end of the second driving member 1035, and the clockwise or counterclockwise rotation of the second driving member 1035 drives the rotating upper seat 102 to rotate clockwise or counterclockwise.

[0102] For example, the second drive component 1035 is a worm gear reducer or a harmonic reducer.

[0103] Due to the self-locking function of the worm gear reducer, the rotating upper seat 102 will not rotate when the second drive component 1035 is closed.

[0104] In some other embodiments, the rotating assembly 103 includes a rotating bearing assembly 1031, a rotating gear disk 1034, and a second drive member 1035. The rotating bearing assembly 1031 is disposed at the center of the rotating base 101, and the rotating upper seat 102 is disposed above the rotating base 101 and cooperates with the rotating bearing assembly 1031. The rotating gear disk 1034 is disposed on the rotating base 101. The second drive member 1035 is disposed on the top surface of the rotating upper seat 102 and its output end passes through the rotating upper seat 102 and meshes with the rotating gear disk 1034.

[0105] Specifically, the rotary bearing assembly 1031 includes a rotary bearing outer ring 10311, a first rotary bearing inner ring 10312, and a first rotary bearing bracket 10313. The rotary bearing outer ring 10311 is connected to the rotating upper seat 102, the first rotary bearing inner ring 10312 is connected to the rotating base 101, the rotary bearing outer ring 10311 is sleeved on the outer circumference of the first rotary bearing inner ring 10312, and the first rotary bearing bracket 10313 is provided between the two.

[0106] The center of the rotating base 101 is provided with a first receiving groove 1011 for accommodating the rotating bearing assembly 1031, and the center of the bottom of the rotating upper seat 102 is provided with a second receiving groove 1021 for accommodating the rotating bearing assembly 1031; after the rotating base 101 and the rotating upper seat 102 are properly arranged, the first receiving groove 1011 and the second receiving groove 1021 together form a cavity for accommodating the rotating bearing assembly 1031.

[0107] Due to the cooperation between the rotating base 101 and the rotating upper seat 102, in reality, a part of the rotating bearing assembly 1031 is located in the first receiving groove 1011 and the other part is located in the second receiving groove 1021; that is, the outer ring 10311 of the slewing bearing is located in the first receiving groove 1011 and the inner ring 10312 of the first slewing bearing is located in the second receiving groove 1021.

[0108] The outer ring 10311 of the slewing bearing is fixedly connected to the rotating base 101, and the inner ring 10312 of the first slewing bearing is connected to the rotating upper seat 102 for rotation.

[0109] Alternatively, it can be said that the first receiving groove 1011 and the second receiving groove 1021 together form a cavity for receiving the rotary bearing assembly 1031, which is then placed inside the cavity.

[0110] The first receiving groove 1011 is also used to receive a rotating gear disk 1034, which is sleeved on the outer ring of the slewing bearing outer ring 10311 and there is no connection between the two.

[0111] The rotating gear disk 1034 is an internal gear disk. The rotating upper seat 102 is driven to rotate clockwise or counterclockwise by the meshing of the inner side of the rotating gear disk 1034 with the gear at the output end of the second driving member 1035 and the clockwise or counterclockwise rotation of the second driving member 1035.

[0112] For example, the second drive component 1035 is a worm gear reducer or a harmonic reducer.

[0113] Due to the self-locking function of the worm gear reducer, the rotating upper seat 102 will not rotate when the second drive component 1035 is closed.

[0114] In some other embodiments, the rotating assembly 103 includes an arc-shaped slide rail 1036 and a slider. The arc-shaped slide rail 1036 is disposed on the rotating base 101, and the slider is disposed at the bottom of the rotating upper seat 102. The arc-shaped slide rail 1036 and the slider are configured in cooperation.

[0115] The rotating base 101 and the rotating upper seat 102 are movably connected on the side away from the arc-shaped slide rail 1036.

[0116] Generally, the two ends of the arc-shaped slide rail 1036 are positioned at two opposite corners of the rotating base 101. The slider is positioned at one opposite corner of the bottom of the rotating upper seat 102. This arrangement allows the slider to slide along one end of the arc-shaped slide rail 1036 to the other end, achieving overlap between the rotating upper seat 102 and the rotating base 101, and then misalignment between the rotating upper seat 102 and the rotating base 101, allowing the rotating upper seat 102 to rotate.

[0117] The arc-shaped slide rail 1036 and the slider are configured to not only enable the rotating upper seat 102 to slide along the arc-shaped slide rail 1036 and thus rotate, but also to maintain a stable sliding connection between the rotating upper seat 102 and the rotating base 101.

[0118] Furthermore, the arc-shaped slide rail 1036 and the slider are configured to have a certain damping. If there is no sufficient external force to make it slide, the rotating upper seat 102 and the rotating base 101 will maintain a stable connection and will not slide.

[0119] In other embodiments, the rotating assembly 103 includes rotating balls and a sliding groove. The sliding groove is disposed on the rotating base 101, and a plurality of rotating balls are disposed at the bottom of the rotating upper seat 102 along the circumferential direction.

[0127] This utility model embodiment also provides a vehicle-mounted folding bracket, such as... Figure 9-13 As shown, it includes a rotating mechanism 1, a fixing mechanism 2, and a folding mechanism 3;

[0128] The fixing mechanism 2 is installed on the vehicle body 4 and is used to support the rotating mechanism 1 and the folding mechanism 3.

[0129] The rotating mechanism 1 is mounted on the fixed mechanism 2 and is used to drive the folding mechanism 3 to rotate so as to adjust it to a suitable direction.

[0130] One end of the folding mechanism 3 is mounted on the rotating mechanism 1, and is used to adjust the unfolded or folded state after the rotating mechanism 1 is rotated to a suitable direction.

[0131] This utility model uses a rotating mechanism 1 to enable the folding mechanism 3 to rotate in different positions on the roof of the vehicle, so that the folding mechanism 3 can be unfolded or folded regardless of the vehicle body 4's position or direction when it is stationary.

[0132] The rotating mechanism 1 can be implemented in any of the above embodiments, which will not be elaborated further here.

[0133] In some embodiments, the folding mechanism 3 includes a first connecting rod 301, a second connecting rod 302, a first worm gear reducer 303, a second worm gear reducer 304, and a third worm gear reducer 305; one end of the first connecting rod 301 is hinged to the rotating mechanism 1, and a first worm gear reducer 303 is provided on one side for driving the first connecting rod 301 to rotate around the hinge point;

[0134] One end of the second connecting rod 302 is connected to the other end of the first connecting rod 301, and a second worm gear reducer 304 is provided on one side for driving the first connecting rod 301 to rotate around the hinge point;

[0135] The other end of the second connecting rod 302 is used to connect to the basketball backboard, and a third worm gear reducer 305 is provided on one side to drive the basketball backboard to rotate around the hinge point.

[0136] For example, the first connecting rod 301 is provided in two sets located on the left and right sides of the rotating mechanism 1 respectively, and a first worm gear reducer 303 is provided on one side of one set;

[0137] The second connecting rod 302 is provided in two sets, which are respectively located inside the two sets of first connecting rods 301, so that after folding, the second connecting rod 302 overlaps with the second connecting rod 301 for storage, reducing the space occupied. One side of one set is provided with a first worm gear reducer 303.

[0138] The second connecting rod 302 is provided in two sets, which are respectively located inside the two sets of first connecting rods 301, so that when folded, the second connecting rod 302 overlaps with the second connecting rod 301 for storage, reducing the space occupied. One side of one set is provided with a first worm gear reducer 303.

[0139] When the folding mechanism 3 needs to be unfolded, the rotating mechanism 1 is first rotated to a suitable position. Then, the first worm gear reducer 303 rotates counterclockwise, lifting the first connecting rod 301 from the limiting rod 202 of the fixing mechanism 2. After rotating to a suitable angle, the first worm gear reducer 303 stops working, and the first connecting rod 301 is locked and cannot rotate. The second worm gear reducer 304 rotates clockwise, rotating the second connecting rod 302 out from the inside of the first connecting rod 301. After rotating to a suitable angle, the second worm gear reducer 304 stops working, and the second connecting rod 302 is locked and cannot rotate. The third worm gear reducer 305 rotates counterclockwise. After rotating to the desired position, the third worm gear reducer 305 stops working, and the functional components installed on the folding mechanism 3 can be used normally. For example, this functional component is a basketball backboard.

[0140] When the folding mechanism 3 needs to be stored, the first worm gear reducer 303 rotates clockwise, rotating the first connecting rod 301 toward the limiting rod 202 until one side of the first connecting rod 301 falls onto the limiting rod 202. At this point, the first worm gear reducer 303 stops working, and the first connecting rod 301 is locked and cannot rotate. The second worm gear reducer 304 rotates counterclockwise, rotating the second connecting rod 302 toward the inside of the first connecting rod 301. After rotating until the first connecting rod 301 overlaps, the second worm gear reducer 304 stops working, and the second connecting rod 302 is locked and cannot rotate. The third worm gear reducer 305 rotates clockwise. After rotating to the desired position, the third worm gear reducer 305 stops working, and the functional components are stored. Finally, the rotating mechanism 1 rotates the reducer back to its initial position.

[0141] Furthermore, the first worm gear reducer 303, the second worm gear reducer 304, and the third worm gear reducer 305 can rotate synchronously to shorten the unfolding or retraction time.

[0142] At least one transversely arranged reinforcing bar 306 is provided on the first link 301 and / or the second link 302 to enhance the strength of the first link 301 and / or the second link 302.

[0143] In other embodiments, the folding mechanism 3 is an arc-shaped scissor structure, which unfolds or folds through staggered connecting rods and push rods.

[0144] In some embodiments, the fixing mechanism 2 includes at least two crossbars 201, which are spaced apart on the vehicle body roof rack 401 along the width direction of the vehicle body 4, and the rotating mechanism 1 is fixed on the at least two crossbars 201.

[0145] The fixing mechanism 2 also includes a limiting rod 202, which is disposed on the side of the vehicle body luggage rack 401 away from at least two crossbars 201, and is used to limit and fix the folding mechanism 3 after folding.

[0146] Two fixing pins 2021 are provided at intervals on the limiting rod 202.

[0147] The spacing between the two fixing pins 2021 matches the width of the folding mechanism 3, so that in the folded state, one side of the folding mechanism 3 is limited by the limiting rod 202 and falls on the limiting rod 202, and is then locked in place by the two fixing pins 2021.

[0148] When using a vehicle-mounted folding bracket, users can select the corresponding hanging mechanism according to their actual needs. The mechanism can fix various items to the end of the roof folding bracket, such as holographic fan screen advertising machines, solar panels, light boxes, and tabletops.

[0149] This utility model provides a vehicle-mounted folding basketball hoop, such as... Figure 14-17 As shown, it includes a vehicle-mounted folding bracket and a basketball backboard 5;

[0150] The basketball backboard 5 is connected to a vehicle-mounted folding bracket and is used to be in either a backboard state or a tabletop state when the vehicle-mounted folding bracket is in an unfolded state.

[0151] The vehicle-mounted folding bracket is connected to the basketball backboard 5 via a quick-release fastener 6.

[0152] This utility model enables the basketball backboard 5 to rotate in different positions on the roof of the vehicle through the rotating mechanism 1, so that the basketball backboard 5 can be adjusted to a suitable position regardless of the vehicle body 4's position or direction when the vehicle body 4 is stationary. Then, the basketball backboard 5 can be used as sports equipment or as a platform for users to use by controlling the unfolded state through the folding mechanism 3.

[0153] It should be noted that the backboard state refers to the basketball backboard 5 being perpendicular to the ground, with its front facing the user, for use in basketball shooting, passing, and other training or recreational activities.

[0154] The "desktop state" refers to the basketball backboard 5 being parallel to the ground with its back facing up, serving as a platform surface for temporary dining, storage, and other living purposes.

[0155] The quick-release fastener 6 allows for the rapid removal or installation of the basketball backboard 5 from the folding mechanism 3.

[0156] The quick-release fastener 6 includes a male plate 61 and a female plate 62. The male plate 61 is provided with at least two locking pins 601 and is located on the back of the basketball backboard 5. The female plate 62 is provided with at least two figure-eight shaped buckles 602 and is connected to the folding mechanism 3. The at least two locking pins 601 are configured to cooperate with the corresponding at least two figure-eight shaped buckles 602.

[0157] The positions and quantities of the figure-eight buckle 602 and the pin 601 are matched, and the basketball backboard 5 can be disassembled or installed by the cooperation between the pin 601 and the figure-eight buckle 602.

[0158] During installation, the locking pin 601 is inserted into the large hole on the upper side of the figure-eight buckle 602. Under the influence of gravity, the basketball backboard 5 moves downward into the small hole on the lower side of the figure-eight buckle 602, thereby achieving fixation.

[0159] During disassembly, the basketball backboard 5 is lifted up, and the locking pin 601 enters the large hole on the upper side of the figure-eight buckle 602 as it is lifted. Then, the basketball backboard 5 can be pulled out to disassemble it.

[0160] Furthermore, a connecting plate 603 for installing the protective net is provided on the lower side of the quick-release fastener 6.

[0161] The connecting plate 603 is installed with the protective net to prevent the basketball from hitting the vehicle body 4 during movement.

[0162] Furthermore, when the basketball backboard 5 is in the desktop state, at least two support rods 502 are provided on the side of the basketball backboard 5 facing the ground.

[0163] By setting at least two support rods 502, the basketball backboard 5 becomes more stable as a tabletop.

[0164] This utility model embodiment also provides a vehicle-mounted folding advertising device, such as... Figure 18-22 As shown, it includes a vehicle-mounted folding bracket and an advertising display mechanism 7; the advertising display mechanism 7 is connected to the vehicle-mounted folding bracket and is used to display advertising information.

[0165] The advertising display unit 7 includes advertising light boxes, holographic fan screen advertising machines, pull-out light boxes, LCD screens, LED screens, transparent screens, crystal film screens, holographic screens, projector screens, and other units used for advertising purposes.

[0166] For example, the advertising display unit 7 adopts an advertising box, and a lighting component 701 is installed inside the advertising box. The lighting component 701 is used to add lighting effects to the advertising box.

[0167] In some embodiments, the advertising box includes a frame 702, a transparent polycarbonate sheet 703, and a back panel 704; the back panel 704 is provided with a frame 702 around its perimeter; the transparent polycarbonate sheet 703 is fixed to the frame 702 and is used as a backboard and also for printing advertising information.

[0168] Specifically, the frame 702 is made of high-strength aluminum alloy profile extrusion molding, with a "U"-shaped channel structure in cross section. The frame 702 is rigidly connected to the back plate 704 around the perimeter through corner bracket connectors to form a rectangular support frame.

[0169] The back panel 704 is made of all-aluminum honeycomb panel with a thickness of 15mm and an aluminum honeycomb core material density of ≤5kg / m³. 3 The back plate 704 is embedded in the groove of the frame 702 and is fastened from the outside of the frame by stainless steel countersunk screws.

[0170] The transparent polycarbonate (PC) endurance sheet 703 is made of polycarbonate (PC) endurance sheet with a thickness of 6-8mm and a UV coating treatment on the surface. The transparent polycarbonate sheet 703 covers the front of the frame 702 and is filled between the transparent polycarbonate sheet 703 and the frame 702 by compression of rubber strips.

[0171] The rubber strip 705 is used not only to fill the gap between the transparent polycarbonate sheet 703 and the frame 702, but also to prevent dust and other contaminants from entering the advertising box.

[0172] The outer contour shape of the advertising box matches the shape of the basketball backboard body.

[0173] In some embodiments, the lighting assembly 701 includes a plurality of light sources, which are arranged longitudinally or laterally on the back panel 704 of the advertising box.

[0174] Specifically, the interval is 100-120mm, which eliminates the overlap of dark areas of adjacent light sources and ensures that the difference in illuminance of the advertising image is ≤%.

[0175] Adjusting the vertical or horizontal spacing of several light sources according to the different aspect ratios of the advertisement content can improve the display effect.

[0176] Meanwhile, since the backplate 704 is made of all-aluminum honeycomb panel, it can also dissipate the heat generated by several light sources.

[0177] For example, the light source includes one or more of LED light strips, LED modules, LED panels, fluorescent tubes, or neon tubes.

[0178] Furthermore, the ball frame is positioned below the front of the advertising box.

[0179] This design integrates the advertising box into both a basketball backboard and a carrier for displaying advertising information, giving the basketball backboard advertising functions in addition to its sports function. This solves the space occupation problem and makes the structure more compact and efficient. At the same time, the lighting component 701 installed inside the advertising box not only increases the advertising display effect but also increases the visibility of the basketball backboard at night or in poor natural light conditions.

[0180] The advertising box can also be made of a 6mm light guide plate and a 10mm all-aluminum honeycomb plate, with a frame wrapped around the outer edge. Drill holes near the wiring position of the light guide plate to lead out wires, and connect the end of the wires to a power bank to make it light up.

[0181] Similarly, the ball frame is set directly below the board surface, and an advertising poster is affixed to the surface of the light guide plate.

[0182] This utility model combines the advertising display mechanism 7 with the vehicle-mounted folding bracket. Through the rotation mechanism 1 and the folding mechanism 3, it can achieve a 3-4 meter high all-round display, which greatly improves the mobility and eye-catching nature of the advertising display.

[0183] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
