Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mobile commercial complexes, and in particular to an LED screen storage device for mobile commercial complexes. Background Technology
[0002] In recent years, mobile shops have experienced rapid development in the commercial sector due to their flexible operating model and wide coverage. As the core display medium for mobile shops to convey commercial information and attract potential customers, the installation and usage of LED screens directly impact the operational efficiency, security, and aesthetics of urban streets.
[0003] Currently, LED screens for mobile shops on the market mainly adopt two traditional methods: one is fixed installation, where the LED screen is rigidly fixed to a specific structure of the shop. While this method can ensure the stability of the LED screen under certain conditions, it cannot adapt to the dynamic changes of moving parts in a mobile shop. When the shop needs to adjust its shape or be stored away, the fixed LED screen becomes a spatial obstacle, making it difficult to achieve coordinated cooperation with the moving structure, which greatly limits the shop's functional expansion and space utilization.
[0004] The second method is manual placement, which involves manually moving the LED screens to designated locations for display and then manually putting them away after use. This method not only consumes a lot of manpower, but manual operation also easily leads to irregular placement of the LED screens, damaging the overall aesthetics of the street. More importantly, LED screens themselves have a certain weight and volume, and if not handled properly during manual handling, they are prone to falling accidentally, posing a safety hazard of injuring passersby and seriously threatening public safety.
[0005] In view of the limitations of the existing technology, there is an urgent need for an LED screen device that can be adapted to the movable parts of the shop and can be automatically unfolded and retracted without human intervention, so as to meet the needs of shops to unfold and display when they open for business and retract and close when they close for business, while taking into account the convenience of operation, the aesthetics of the street and the safety of use. Utility Model Content
[0006] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an LED screen storage device for mobile commercial establishments, which can solve the problem of LED screen devices that are adapted to the moving parts of mobile shops and can automatically unfold and store without human intervention.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a mobile commercial LED screen storage device, comprising a movable structure, an LED screen, two sets of hinges, an electric push rod, and a locking mechanism. The movable structure and the LED screen are movably connected through two symmetrical hinges. The two ends of the electric push rod are respectively linked to the movable structure and the LED screen through pins.
[0008] Preferably, one end of the electric push rod is movably connected to the connecting lug 1 below the movable structure via a pin, and the other end is fixedly connected to the LED screen via a pin, connecting lug 2, and a fixed base; both the connecting lug 1 and the fixed base are fixed by bolts inserted into bolt holes, and the bolt holes are equidistantly distributed on the connecting lug 1 and the fixed base.
[0009] Preferably, the locking mechanism includes a fixing block and a housing block, which are respectively fixed to the corresponding sides of the movable structure and the LED screen. The fixing block and the housing block are mechanically locked by a rotating shaft and a limiting block.
[0010] Preferably, the lower surface of the fixing block of the locking mechanism is provided with a slot that matches the top view contour of the rotating shaft and the limiting block, and the inner wall of the slot is provided with a cylindrical groove that is the same length as the limiting block.
[0011] Preferably, a drive motor is installed inside the housing block, the output end of the drive motor is fixedly connected to the rotating shaft, and a limit block is fixed at the upper end of the rotating shaft.
[0012] Preferably, the two sets of hinges are symmetrically distributed about the central axis of the movable structure, and each set contains two hinges. The rotation axis of the hinges serves as the fulcrum for the rotation of the LED screen relative to the movable structure.
[0013] The fixing block and the housing block are kept vertically aligned.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This mobile commercial space uses an LED screen storage device. The movable structure and the LED screen are connected by two symmetrical hinges. The hinges act as fulcrums, allowing the LED screen to rotate relative to the movable structure. When the LED screen needs to be unfolded, an electric push rod is activated and extends: one end of the electric push rod is movably connected to a connecting lug 1 below the movable structure via a pin, and the other end is fixedly connected to one side of the LED screen via a pin, a connecting lug 2, and a fixed base (both the connecting lug 1 and the fixed base are fixed by bolts inserted into bolt holes), forming a linkage structure. The extension force of the electric push rod is transmitted through the pins at both ends, pushing the LED screen to rotate downwards around the hinges until the LED screen unfolds to the preset working position. At this time, the fixed block on one side of the movable structure and the housing block on one side of the LED screen are aligned vertically, preparing for locking.
[0016] This mobile commercial LED screen storage device uses a drive motor inside the housing block to rotate the output shaft. A limit block is fixed at the upper end of the rotating shaft. In the initial state, the limit block matches the top view contour of the groove on the lower surface of the fixed block (the groove size is consistent with the rotating shaft and the limit block). The rotating shaft and the limit block move upward into the groove of the fixed block. Then, the drive motor drives the rotating shaft to rotate (the rotation angle is adapted to the cylindrical groove), so that the limit block is locked into the pre-set cylindrical groove on the inner wall of the groove (the length of the cylindrical groove is consistent with the length of the limit block). The cooperation between the limit block and the cylindrical groove forms a mechanical lock, restricting the up and down movement and rotation of the rotating shaft, thereby rigidly connecting the fixed block and the housing block, and realizing the stable locking of the movable structure and the LED screen in the unfolded position.
[0017] The mobile commercial LED screen storage device uses a drive motor that rotates in the opposite direction, causing the rotating shaft and limiting block to rotate. This causes the limiting block to exit from the cylindrical groove and return to a state that matches the groove's contour. The rotating shaft and limiting block then move downwards from the groove, releasing the locking between the fixing block and the housing block. The electric push rod retracts, pulling the LED screen upwards around the hinge axis via pins at both ends, until the LED screen is folded and stored under the movable structure, completing the storage action.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a mobile commercial LED screen storage device includes a movable structure 8, an LED screen 9 and two locking mechanisms. The LED screen 9 is located below the movable structure 8, and the locking mechanisms are fixedly connected to one side of the movable structure 8 and the LED screen 9.
[0030] The locking mechanism includes two housing blocks 11 and two fixing blocks 10. The fixing blocks 10 are fixedly installed on one side of the movable structure 8, and the housing blocks 11 are fixedly installed on one side of the LED screen 9. The fixing blocks 10 and housing blocks 11 are aligned vertically.
[0031] Four hinges 1 are fixedly installed at the connection between the movable structure 8 and the LED screen 9, in pairs and symmetrically arranged on the left and right. The movable structure 8 is movably connected to the LED screen 9 set on the hinges 1. The movable structure 8 and the LED screen 9 are connected by two pairs of symmetrical hinges 1. The hinges 1 serve as rotation fulcrums, allowing the LED screen 9 to rotate relative to the movable structure 8.
[0032] Two connecting lugs 2 are provided below the movable structure 8. Four equally spaced bolt holes 7 are provided on the connecting lugs 2. The connecting lugs 2 are fixedly connected to the movable structure 8 by bolts inserted into the bolt holes 7. The connecting lugs 2 are fixedly connected with the same pins 5. The structure is symmetrical about the middle axis of the movable structure 8.
[0033] An electric push rod 3 is movably connected to the same pin 5. One end of the electric push rod 3 is fixedly connected to the pin 5. The pin 5 is fixedly connected to the connecting ear 2 4. The connecting ear 2 4 is fixedly connected to the fixed base 6. The fixed base 6 has four equidistant and identical bolt holes 7. The connecting ear 2 4 is fixedly connected to one side of the LED screen 9 by the fixed base 6 and the bolts inserted into the bolt holes 7. When the LED screen 9 needs to be unfolded, the electric push rod 3 starts and extends: one end of the electric push rod 3 is movably connected to the connecting ear 1 2 below the movable structure 8 by the pin 5, and the other end is fixedly connected to one side of the LED screen 9 by the pin 5, the connecting ear 2 4 and the fixed base 6 (the connecting ear 2 and the fixed base 6 are both fixed by the bolts inserted into the bolt holes 7), forming a linkage structure. The extension force of the electric push rod 3 is transmitted through the pins 5 at both ends, pushing the LED screen 9 to rotate downward with the hinge 1 as the axis until the LED screen 9 unfolds to the preset working position.
[0034] A drive motor 13 is fixedly installed inside the housing block 11. A rotating shaft 12 is fixedly connected to the output end of the drive motor 13. A limiting block 14 is fixedly connected to the upper end of the outer wall of the rotating shaft 12.
[0035] The lower surface of the fixing block 10 has a rotating shaft 12 and a limiting block 14. (Top view interface) Figure 1 The groove 15 is of the same size, and the inner wall of the groove 15 is rotaryly cut with a cylindrical groove 16 of the same length as the limiting block 14.
[0036] The movable structure 8 and the LED screen 9 are connected by a rotating shaft 12 and a limiting block 14 in a slot 15 and a cylindrical groove 16. The drive motor 13 inside the housing block 11 works, driving the rotating shaft 12 at its output end to rotate. The limiting block 14 is fixed at the upper end of the rotating shaft 12. In the initial state, the limiting block 14 matches the top view contour of the slot 15 on the lower surface of the fixed block 10 (the size of the slot 15 is consistent with the rotating shaft 12 and the limiting block 14). The rotating shaft 12 and the limiting block 14 move upward into the fixed position. Within the slot 15 of block 10, the drive motor 13 drives the rotating shaft 12 to rotate (the rotation angle is adapted to the cylindrical slot 16), causing the limiting block 14 to engage in the pre-set cylindrical slot 16 on the inner wall of the slot 15 (the length of the cylindrical slot 16 is the same as the length of the limiting block 14). The cooperation between the limiting block 14 and the cylindrical slot 16 forms a mechanical lock, restricting the up and down movement and rotation of the rotating shaft 12, thereby rigidly connecting the fixed block 10 and the housing block 11, and achieving stable locking of the movable structure 8 and the LED screen 9 in the unfolded position.
[0037] Working principle: The movable structure 8 and the LED screen 9 are connected by two symmetrical hinges 1. The hinges 1 serve as a pivot point, allowing the LED screen 9 to rotate relative to the movable structure 8. When the LED screen 9 needs to be unfolded, the electric push rod 3 is activated and extended: one end of the electric push rod 3 is movably connected to the connecting lug 1 2 below the movable structure 8 via a pin 5, and the other end is fixedly connected to one side of the LED screen 9 via a pin 5, a connecting lug 2 4, and a fixed base 6 (the connecting lug 2 and the fixed base 6 are both fixed by bolts inserted into bolt holes 7), forming a linkage structure. The extension force of the electric push rod 3 is transmitted through the pins 5 at both ends, pushing the LED screen 9 to rotate downward around the hinges 1 until the LED screen 9 unfolds to the preset working position. At this time, the fixed block 10 on one side of the movable structure 8 and the housing block 11 on one side of the LED screen 9 are aligned vertically, preparing for locking.
[0038] When the LED screen 9 is unfolded into place, the locking mechanism is activated to ensure structural stability: the drive motor 13 inside the housing block 11 works, driving the rotating shaft 12 at its output end to rotate. The upper end of the rotating shaft 12 is fixed with a limit block 14. In the initial state, the limit block 14 matches the top view contour of the slot 15 on the lower surface of the fixed block 10 (the size of the slot 15 is consistent with the rotating shaft 12 and the limit block 14). The rotating shaft 12 and the limit block 14 move upward into the slot 15 of the fixed block 10. Then the drive motor 13 drives the rotating shaft 12 to rotate (the rotation angle is adapted to the cylindrical slot 16), so that the limit block 14 is inserted into the cylindrical slot 16 preset on the inner wall of the slot 15 (the length of the cylindrical slot 16 is consistent with the length of the limit block 14). The cooperation between the limit block 14 and the cylindrical slot 16 forms a mechanical lock, restricting the up and down movement and rotation of the rotating shaft 12, thereby rigidly connecting the fixed block 10 and the housing block 11, realizing the stable locking of the movable structure 8 and the LED screen 9 in the unfolded position.
[0039] When the LED screen 9 needs to be stored, the device performs the opposite action to unfolding: the drive motor 13 rotates in the opposite direction, driving the rotating shaft 12 and the limiting block 14 to rotate, causing the limiting block 14 to exit from the cylindrical groove 16 and return to the state of matching the contour of the groove 15. The rotating shaft 12 and the limiting block 14 move down from the groove 15, releasing the locking of the fixing block 10 and the housing block 11. The electric push rod 3 retracts, pulling the LED screen 9 upward around the hinge 1 axis through the pins 5 at both ends, until the LED screen 9 is folded and stored under the movable structure 8, completing the storage action.
[0040] Structural Description:
[0041] Hinges 1: Four hinges 1 are fixedly installed at the connection between the movable structure 8 and the LED screen 9, in pairs and symmetrically arranged. The movable structure 8 and the LED screen 9 are movably connected through two pairs of symmetrical hinges 1. The hinges 1 serve as a fulcrum for rotation, allowing the LED screen 9 to rotate relative to the movable structure 8, providing a rotational basis for the unfolding and folding of the LED screen 9.
[0042] Connecting lug 1 2: Two connecting lugs 1 2 are provided below the movable structure 8. There are four equidistant bolt holes 7 on the connecting lugs 1 2. The connecting lugs 1 2 are fixedly connected to the movable structure 8 by bolts inserted into the bolt holes 7. The structure is symmetrical about the central axis of the movable structure 8. The function of the connecting lugs 1 2 is to connect the movable structure 8 and the electric push rod 3. The bolt holes 7 are used to fix the connecting lugs 1 2 to the movable structure 8 by bolts to ensure the stability of the connection. The symmetrical arrangement makes the force balanced.
[0043] Pin 5: Pin 5 is fixedly connected to connecting lug 1 2. Electric push rod 3 is movably connected to pin 5. Pin 5 is fixedly connected to one end of electric push rod 3. Connecting lug 2 4 is fixedly connected to pin 5. The function of pin 5 is to realize the movable connection between electric push rod 3 and connecting lug 1 2 and connecting lug 2 4, so as to ensure that electric push rod 3 can rotate flexibly during extension and retraction, thereby effectively transmitting power.
[0044] Electric push rod 3: One end of the electric push rod 3 is movably connected to the connecting lug 2 below the movable structure 8 via a pin 5, and the other end is fixedly connected to one side of the LED screen 9 via a pin 5, a connecting lug 4, and a fixed base 6. When the LED screen 9 needs to be unfolded, the electric push rod 3 starts and extends. Its extension force is transmitted through the pins 5 at both ends, pushing the LED screen 9 to rotate downward around the hinge 1 axis. When the LED screen 9 needs to be retracted, the electric push rod 3 retracts, pulling the LED screen 9 to rotate upward around the hinge 1 axis via the pins 5 at both ends. The electric push rod 3 provides power for the unfolding and retraction of the LED screen 9 and is the key driving component for realizing the movement of the LED screen 9.
[0045] Connecting ear plate 2 4: Connecting ear plate 2 4 is fixedly connected to a pin 5 and a fixed base 6. The fixed base 6 has four equidistant bolt holes 7. Connecting ear plate 2 4 is fixedly connected to one side of the LED screen 9 by inserting the fixed base 6 and bolts into the bolt holes 7. The function of connecting ear plate 2 4 is to connect the electric push rod 3 and the LED screen 9. The bolt holes 7 are used to fix connecting ear plate 2 4 and fixed base 6 to the LED screen 9 with bolts, ensuring that the electric push rod 3 can stably transmit power to the LED screen 9.
[0046] Fixed base 6: Fixed base 6 is fixedly connected to connecting ear piece 2 4. The bolt hole 7 on it is used to fix the connecting ear piece 2 4 and fixed base 6 as a whole on the LED screen 9 with bolts, which enhances the stability of the connection between connecting ear piece 2 4 and LED screen 9.
[0047] Bolt holes 7: Four equally spaced bolt holes 7 are provided on both the connecting ear 1 2 and the fixed base 6 for bolt insertion. These holes are used to fix the connecting ear 1 2 to the movable structure 8, and to fix the connecting ear 2 4, the fixed base 6 and the LED screen 9. This is an important structure to ensure the stable connection of each component.
[0048] Active structure 8: As the main load-bearing structure of the device, it provides the installation foundation for components such as LED screen 9, hinge 1, connecting ear 1 2, and fixing block 10, and supports the weight of the entire device and the forces during operation.
[0049] LED screen 9: This is the core functional component of the device, used for information display. It can be deployed and stored by connecting with the movable structure 8 and driving related components.
[0050] Fixed block 10: Fixed block 10 is fixedly installed on one side of the movable structure 8, and is vertically aligned with the shell block 11. Its lower surface has a top view interface with the rotation shaft 12 and the limiting block 14. Figure 1 The slot 15 is of the same size, and the inner wall of the slot 15 is cut with a cylindrical groove 16 of the same length as the limiting block 14. The fixing block 10 and the housing block 11 cooperate to lock the movable structure 8 and the LED screen 9. The slot 15 is used to accommodate the rotating shaft 12 and the limiting block 14. The cylindrical groove 16 is used to lock the limiting block 14 when locking, forming a mechanical lock.
[0051] Housing block 11: Housing block 11 is fixedly installed on one side of LED screen 9. The drive motor 13 is fixedly installed inside, providing installation space and protection for components such as drive motor 13 and rotating shaft 12. At the same time, it cooperates with fixed block 10 to complete the locking action.
[0052] Rotating shaft 12: The rotating shaft 12 is fixedly connected to the output end of the drive motor 13. A limit block 14 is fixedly connected to the upper end of its outer wall. Under the drive of the drive motor 13, the rotating shaft 12 can rotate, thereby driving the limit block 14 to rotate, realizing the cooperation and separation of the limit block 14 with the slot 15 and the cylindrical slot 16. It is a key component for transmitting the power of the drive motor 13.
[0053] Drive motor 13: It is fixedly installed inside the housing block 11, and its output end is fixedly connected to the rotating shaft 12. It provides power for the rotation of the rotating shaft 12 and the limit block 14, and is the power source for locking and unlocking the locking mechanism.
[0054] Limiting block 14: It is fixedly connected to the upper end of the outer wall of the rotating shaft 12. In the initial state, it matches the top view contour of the groove 15 on the lower surface of the fixed block 10. Under the drive of the drive motor 13, it can rotate with the rotating shaft 12. When it rotates to cooperate with the cylindrical groove 16, it forms a mechanical lock, which restricts the vertical movement and rotation of the rotating shaft 12, thereby realizing the rigid connection between the fixed block 10 and the housing block 11. When rotating in the opposite direction, it can be disengaged from the cylindrical groove 16 and the lock is released.
[0055] Groove 15: It is formed on the lower surface of the fixed block 10 and has the same size as the rotating shaft 12 and the limiting block 14. It is used to accommodate the rotating shaft 12 and the limiting block 14 when the locking mechanism is working, and to provide space for their entry.
[0056] Cylindrical groove 16: It is formed on the inner wall of the groove 15 and has the same length as the limiting block 14. It is used to accommodate the limiting block 14 when it is rotated to a specific angle. It cooperates with the limiting block 14 to form a mechanical lock, ensuring that the movable structure 8 and the LED screen 9 are stably locked in the unfolded position.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
