[0020] With the acceleration of urbanization, the value of underground commercial space, as a key vehicle for intensive land use, is becoming increasingly prominent. Underground commercial space plays an irreplaceable and crucial role in alleviating surface traffic pressure, enhancing urban commercial vitality, and optimizing urban spatial layout. However, traditional underground commercial spaces suffer from numerous design and planning deficiencies, primarily manifested in rigid layouts and limited functionality. These issues result in fixed passenger passageways in underground commercial spaces, making them difficult to adapt to dynamically changing passenger flow demands.

[0021] For example, during peak hours with heavy foot traffic, limited passageways often cannot accommodate the large number of people flowing through, easily leading to congestion. This not only affects consumers' shopping experience but also poses a potential safety hazard. During off-peak hours, when foot traffic is lower, the spacious passageways originally designed for peak hours remain largely unused, resulting in a waste of space resources. This fixed layout model cannot flexibly respond to changes in passenger flow at different times of the day, limiting the efficient utilization and sustainable development of underground commercial space. Therefore, how to break through the limitations of traditional underground commercial space layout and optimize its kinetic design to enable it to better adapt to dynamic changes in passenger flow has become a pressing issue in current urban planning and commercial development.

[0022] Based on this, see Figure 1 An embodiment of the present application provides an underground commercial space building structure, including a fixed wall 10 and a movable wall 11. An indoor space 12 is enclosed between the fixed wall 10 and the movable wall 11. A driving mechanism 13 is provided between the fixed wall 10 and the movable wall 11. The driving mechanism 13 is used to drive the movable wall 11 closer to or away from the fixed wall 10 to adjust the size of the indoor space 12.

[0023] Specifically, the fixed wall 10 is used to be fixed on the ground, and the movable wall 11 is installed on the ground and can move in the horizontal direction to move closer to or away from the fixed wall 10. Exemplarily, the maximum movement displacement of the movable wall 11 can be 1-1.5m. The fixed wall 10 and the movable wall 11 enclose an indoor space 12, and the indoor space 12 is used for commercial operations, such as as the interior space of a shop. A doorway 1114 is provided on the movable wall 11 for customers to enter the indoor space 12 from the passenger flow channel. The driving mechanism 13 is arranged between the fixed wall 10 and the movable wall 11, and is used to provide power to drive the movable wall 11 to move, so as to flexibly adjust the position of the movable wall 11 according to demand. This mechanism can not only dynamically adjust the size of the indoor space 12 to adapt to different business operation needs, but also simultaneously adjust the width of the passenger flow channel, thereby optimizing the traffic capacity and space utilization efficiency of the underground commercial space.

[0024] In order to ensure that the movable wall 11 moves smoothly and efficiently while reducing the friction between it and the ground, this embodiment provides two optimization solutions, namely: 1. A number of rollers are set at the bottom of the movable wall 11. These rollers can disperse the weight of the movable wall 11 and reduce the friction with the ground by rolling. The material and size of the rollers can be optimized according to the actual usage scenario to ensure their wear resistance and load-bearing capacity; 2. A slide rail is prefabricated on the ground, and the bottom of the movable wall 11 is designed to be slidably matched with the slide rail. The close fit between the slide rail and the bottom of the movable wall 11 can reduce the friction between it and the ground. The slide rail can also provide a precise moving path for the movable wall 11, ensuring its stability and straightness during movement, and reducing problems such as movement jamming caused by uneven ground or interference from debris.

[0025] The underground commercial space building structure provided in the embodiment of the present application is used to be arranged on both sides of the passenger flow channel, with the movable wall 11 facing the passenger flow channel, and the door opening 1114 on the movable wall 11 also facing the passenger flow channel, so that customers can enter the indoor space 12 from the passenger flow channel to shop. Figure 2 , several underground commercial space building structures provided by the embodiment of the present application are arranged side by side on each side of the passenger flow road. When there is a large peak flow of people, for example, the flow of people is greater than 2 people / m 2 When the driving mechanism 13 is used to drive the movable wall 11 close to the fixed wall 10, the movable wall 11 shrinks inward to increase the width of the passenger flow channel, effectively improving the traffic capacity of the passenger flow channel, avoiding crowd congestion, ensuring smooth passage for customers, and optimizing the shopping experience. 2When it is time, the driving mechanism 13 is used to drive the movable wall 11 away from the fixed wall 10, and the movable wall 11 expands outward to restore the commercial space area on both sides of the passenger flow passage, realizing the reuse of the space, and the passenger flow passage is restored to the original width. Compared with the prior art, this flexible space layout of the present application can be dynamically adjusted according to the passenger flow demand, which not only avoids congestion during peak hours but also prevents the waste of idle space during low peak hours.

[0026] Based on the above solution, it further includes a controller and a multi-source perception system deployed on the passenger flow passage. The driving mechanism 13 and the multi-source perception system are respectively connected to the controller. The multi-source perception system is used to collect the pedestrian flow data on the passenger flow road. The controller can analyze the pedestrian flow on the current passenger flow road by receiving the data fed back by the multi-source perception system, and automatically control the driving mechanism 13 to work according to the preset pedestrian flow threshold and control logic, so as to realize the retraction and expansion of the movable wall 11, achieving the purpose of dynamically adjusting the width of the passenger flow passage according to the passenger flow demand.

[0027] In some embodiments, referring to Figure 1 、 Figure 2 , the fixed wall 10 includes a rear wall 101 and rear side walls 102 connected to both sides thereof. The movable wall 11 includes a front wall 111 and front side walls 112 connected to both sides thereof. The two front side walls 112 correspond to the two rear side walls 102 one by one and partially overlap. The driving mechanism 13 is arranged between the rear side wall 102 and the front side wall 112 and is used to drive the front wall 111 to approach or move away from the rear wall 101.

[0028] Specifically, the fixed wall 10 includes a rear wall 101 and two rear side walls 102. The two rear side walls 102 are arranged in parallel and are respectively connected to both sides of the rear wall 101. The rear wall 101 and the two rear side walls 102 form a C-shaped wall structure in cross-section. The movable wall 11 includes a front wall 111 and two front side walls 112. The two front side walls 112 are arranged in parallel and are respectively connected to both sides of the front wall 111. The front wall 111 and the two front side walls 112 form a C-shaped wall structure in cross-section. The front wall 111 is arranged in parallel with the rear wall 101. The two front side walls 112 correspond to the two rear side walls 102 one by one. The front side wall 112 is parallel to and partially overlaps with the corresponding rear side wall 102. Thus, an indoor space 12 can be enclosed between the front wall 111, the front side walls 112, the rear wall 101 and the rear side walls 102. Among them, the front wall 111 faces the passenger flow passage, and a door opening 1114 is provided thereon. The bottoms of the two front side walls 112 can be provided with rollers or structures that slide配合 with a slide rail. The driving mechanism 13 includes two groups, which are respectively arranged between the two groups of front side walls 112 and rear side walls 102; each group of driving mechanism 13 includes two, and the two driving mechanisms 13 are arranged at intervals up and down.

[0029] When it is in a peak period with a large pedestrian flow, for example, the pedestrian flow > 2 people / m 2When the front side wall 112 is driven by the driving mechanism 13, the front wall 111 is driven closer to the rear wall 101, and the front wall 111 is retracted to increase the width of the passenger flow channel, effectively improving the traffic capacity of the passenger flow channel, avoiding crowd congestion, ensuring smooth passage for customers, and optimizing the shopping experience. 2 When the front side wall 112 is moved away from the rear wall 101 by the driving mechanism 13, the front wall 111 is expanded outward to restore the commercial space area on both sides of the passenger flow channel, thereby realizing space reuse and restoring the passenger flow channel to its original width.

[0030] The driving mechanism 13 can be a linear drive, such as a cylinder, a hydraulic cylinder, an electric push rod, etc. Of course, other existing structures can also be used, as long as it can drive the movable wall 11 to move. No specific limitation is made here.

[0031] In some embodiments, see Figure 1 The driving mechanism 13 includes a driving motor 131, a threaded rod 132 and a sliding guide column 133. The driving motor 131 is arranged on the fixed wall 10. One end of the threaded rod 132 is connected to the output shaft of the driving motor 131. The sliding guide column 133 is arranged on the movable wall 11. An internal threaded hole extending along the axial direction of the sliding guide column 133 is provided. The other end of the threaded rod 132 is threadedly connected to the internal threaded hole.

[0032] Specifically, the drive motor 131 is fixed on the outer surface of the rear side wall 102, the output shaft of the drive motor 131 is parallel to the moving direction of the movable wall 11, the threaded rod 132 is horizontally arranged and one end thereof is fixedly connected to the output shaft of the drive motor 131, the outer surface of the front side wall 112 is provided with a front side wall groove 1121 parallel to its moving direction, the sliding guide column 133 is fixed in the front side wall groove 1121, and the other end of the threaded rod 132 is threadedly connected to the internal threaded hole of the sliding guide column 133.

[0033] During peak hours with heavy passenger flow, the output shaft of the drive motor 131 drives the threaded rod 132 to rotate forward. Since the threaded rod 132 is threadedly engaged with the internal threaded hole in the guide post 133, the rotation of the threaded rod 132 pushes the guide post 133 to move along its axial direction. The movement of the guide post 133 drives the movable wall 11 to move horizontally closer to the fixed wall 10, thereby increasing the width of the passenger flow channel and improving the traffic capacity of the passenger flow channel. During low-peak hours with less passenger flow, the output shaft of the drive motor 131 drives the threaded rod 132 to rotate reversely. Since the threaded rod 132 is threadedly engaged with the internal threaded hole in the guide post 133, the rotation of the threaded rod 132 pushes the guide post 133 to move along its axial direction. The movement of the guide post 133 drives the movable wall 11 to move horizontally away from the fixed wall 10, thereby realizing space reuse and restoring the passenger flow channel to its original width.

[0034] In some embodiments, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The outer side and / or inner side of the movable wall 11 is provided with a seat board 14 rotatably connected thereto, and the seat board 14 is connected to the fixed seat 17 through a transmission mechanism 15; when the movable wall 11 is away from the fixed wall 10, the seat board 14 on the outer side of the movable wall 11 flips upward to a stored state, and the seat board 14 on the inner side of the movable wall 11 flips downward to an expanded state; when the movable wall 11 approaches the fixed wall 10, the seat board 14 on the outer side of the movable wall 11 flips downward to the expanded state, and the seat board 14 on the inner side of the movable wall 11 flips upward to a stored state.

[0035] Specifically, one side of the seat panel 14 is rotatably connected to the front wall 111 of the movable wall 11, allowing the seat panel 14 to flip up and down. The seat panel 14 may include multiple seats, and these seats may be located on either the inside or outside of the front wall 111, or both. The outside refers to the side outside the interior space 12, and the inside refers to the side inside the interior space 12. A fixing base 17 is located above the movable wall 11 and fixedly connected to a fixed structure within the underground commercial space, for example, the fixing base 17 is fixedly connected to the floor. The fixing base 17 is connected to the seat panel 14 via a transmission mechanism 15. During the movement of the movable wall 11, the transmission mechanism 15 can drive the seat panel 14 to flip up or down. When the seat panel 14 flips downward to a horizontal position, it is in an extended position; when the seat panel 14 flips upward to a vertical position, it is in a stowed position.

[0036] Accordingly, during peak hours with heavy foot traffic, the movable wall 11 moves closer to the fixed wall 10 to widen the passenger passageway and improve its capacity. During this process, the inner seat panels 14 are simultaneously retracted to avoid occupying the interior space 12, while the outer seat panels 14 are simultaneously deployed, allowing customers in the passenger passageway to rest on the outer seat panels 14, extending their stay time and improving the attractiveness of the shop interface and consumer conversion efficiency. During low-peak hours with less foot traffic, the movable wall 11 moves away from the fixed wall 10, allowing the passenger passageway to return to its original width. During this process, the outer seat panels 14 are simultaneously retracted to avoid occupying the passenger passageway, while the inner seat panels 14 are simultaneously deployed, allowing customers to rest on the inner seat panels 14, achieving a deep integration of the customer rest area and the interior space 12. While resting, customers naturally engage in product browsing in the interior space 12, stimulating spontaneous consumption through close visual contact, forming a non-mandatory consumption guidance path, and reconstructing an integrated rest-consumption commercial scene.

[0037] In some embodiments, see Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 The movable wall 11 is provided with a storage groove 1111 , and the seat plate 14 can be flipped upward and stored in the storage groove 1111 .

[0038] Specifically, a storage slot 1111 is provided on the front wall 111 of the movable wall 11. One side of the seat panel 14 is rotatably connected to the lower portion of the bottom surface of the storage slot 1111 via a rotating block 141, so that the seat panel 14 can be flipped upward and stored in the storage slot 1111. Accordingly, by providing the storage slot 1111, the seat panel 14 can be stored in the storage slot 1111 when not in use, thereby preventing the seat panel 14 from occupying excessive space.

[0039] In some embodiments, see Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 A fitting groove 1112 is provided in the storage groove 1111, and a backrest board 18 is fitted in the fitting groove 1112, and the backrest board 18 is connected to the transmission mechanism 15; when the movable wall 11 is away from the fixed wall 10, the backrest board 18 on the outside of the movable wall 11 is fitted in the fitting groove 1112, and the backrest board 18 on the inside of the movable wall 11 is pushed outward to the outside of the fitting groove 1112; when the movable wall 11 is close to the fixed wall 10, the backrest board 18 on the outside of the movable wall 11 is pushed outward to the outside of the fitting groove 1112, and the backrest board 18 on the inside of the movable wall 11 is fitted in the fitting groove 1112.

[0040] Specifically, the bottom surface of the storage groove 1111 is provided with an interlocking groove 1112, and the backrest board 18 can be interlocked in the interlocking groove 1112 and connected to the transmission mechanism 15. The transmission mechanism 15 can drive the backrest board 18 to move horizontally so that the backrest board 18 is pushed outward to the outside of the interlocking groove 1112 or embedded in the interlocking groove 1112.

[0041] Correspondingly, when a seat panel 14 is unfolded, the backrest panel 18 that matches the seat panel 14 is simultaneously pushed outward to the outside of the fitting groove 1112, so that it is convenient for customers to sit on the outer seat panel 14 and rest on the backrest panel 18; when a seat panel 14 is stored, the backrest panel 18 that matches the seat panel 14 is simultaneously fitted inward in the fitting groove 1112 to avoid taking up too much extra space.

[0042] To enhance the comfort of customers resting on the seat panel 14 in winter, soft-padded structures are provided on opposite sides of the seat panel 14 and backrest 18. Pressure sensors may be provided between the soft-padded structures and the seat panel 14 and backrest 18, and a heating element may be provided within the soft-padded structures. When a customer sits on the seat panel 14 with their back in close contact with the backrest 18, the pressure sensor receives external pressure, energizing the heating element. This heats the seat panel 14 and backrest 18, thereby enhancing the comfort of customers resting on the seat panel 14 in winter.

[0043] In some embodiments, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 The transmission mechanism 15 includes a transmission tooth 151 provided on the seat plate 14, a first gear 152 provided on the movable wall 11 and meshing with the transmission tooth 151 for transmission, a worm gear 153 coaxially connected to the first gear 152, a worm 154 vertically provided on the movable wall 11 and meshing with the worm gear 153 for transmission, a transmission rod 155 coaxially connected to the worm 154, a transmission shaft 156 vertically provided on the movable wall 11 and connected to the transmission rod 155 for transmission, a transmission gear 157 connected to the upper end of the transmission shaft 156, and a transmission rack 158 meshing with the transmission gear 157 for transmission. The transmission rack 158 is parallel to the moving direction of the movable wall 11 and is connected to the fixed seat 17.

[0044] Specifically, the seat plate 14 is provided with curved grooves 142 on either side of the rotating block 141. Each curved groove 142 is provided with a plurality of transmission teeth 151. Two first gears 152 are rotatably mounted within the receiving groove 1111. The two first gears 152 respectively mesh with the transmission teeth 151 within the two curved grooves 142. The first gears 152 can be directly meshed with the transmission teeth 151, or they can be meshed with the transmission teeth 151 via a second gear 161 within the receiving groove 1111. The bottom surface of the storage slot 1111 is provided with two parallel chute holes 1115, each of which is arranged vertically. A transmission rod 155 is rotatably mounted within each chute hole 1115. The lower end of the transmission rod 155 is fixedly connected to a worm 154, and the two worms 154 are respectively meshed with two worm wheels 153. A vertically arranged transmission shaft 156 is also rotatably connected within the front wall 111. The lower end of the transmission shaft 156 extends into the storage slot 1111 and is transmission-connected to the two transmission rods 155. The transmission method between the transmission shaft 156 and the transmission rods 155 can be a chain drive, a belt drive, or a gear drive. The upper end of the transmission shaft 156 extends upward to the top of the front wall 111 and is fixedly connected to a transmission gear 157. The transmission gear 157 is meshed with a transmission rack 158, and the transmission rack 158 is connected to the fixed base 17. Among them, the fixed seat 17 can be a long strip structure parallel to the moving direction of the movable wall 11. The bottom of the fixed seat 17 is provided with a T-shaped slot extending along its length direction. The transmission rack 158 is provided on the side wall of the T-shaped slot. The transmission gear 157 can move in the T-shaped slot and engage with the transmission rack 158.

[0045] The transmission principle of the transmission mechanism 15 is as follows: when the driving mechanism 13 drives the movable wall 11 to move, the movable wall 11 drives the transmission gear 157 to move along the transmission rack 158, and the mutual meshing of the transmission rack 158 and the transmission gear 157 drives the transmission shaft 156 to rotate, and the transmission shaft 156 drives the two transmission rods 155 to rotate, and the transmission rod 155 synchronously drives the worm 154 to rotate, and the worm 154 drives the worm wheel 153 meshing with it to rotate, and the worm wheel 153 synchronously drives the first gear 152 to rotate, and the first gear 152 drives the second gear 161 to rotate, and the second gear 161 drives the seat plate 14 to flip over through the transmission teeth 151 in the curved groove 142, so that the seat plate 14 is unfolded or stored from the storage groove 1111.

[0046] In some embodiments, see Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 The transmission rod 155 has two external thread sections with opposite rotation directions, and the two external thread sections are respectively threadedly connected to the slide block 159. The slide block 159 is hinged to the rotating rod 160. The rotating rods 160 on the two slide blocks 159 are cross-arranged and hinged to the backrest plate 18.

[0047] When the transmission rod 155 rotates, it can drive the two slide blocks 159 thereon to move closer to or away from each other, and then use the cooperation of the cross-arranged rotating rods 160 to drive the backrest board 18 to be pushed outward to the outside of the fitting groove 1112 or to be fitted inward into the fitting groove 1112.

[0048] Exemplarily, each slide slot hole 1115 is provided with a guide slot opening 1116 on the side walls on both sides of the transmission rod 155, and a guide slot block 162 is provided in the guide slot opening 1116.

The lower end of the support rod 19 slides in the movable groove 1113 and is supported at the lower end of the movable groove 1113 after the seat plate 14 is unfolded.

[0050] Accordingly, the sliding fit between the support rod 19 and the movable slot 1113 allows the seat panel 14 to be deployed and retracted. When the seat panel 14 is deployed, the lower end of the support rod 19 slides to the lower end of the movable slot 1113, providing stable support for the seat panel 14, improving the stability and load-bearing capacity of the deployed seat panel 14, and enhancing the safety of the customer sitting on the seat panel 14.

[0051] There can be one or two support rods 19. The bottom surface of the seat panel 14 can be provided with a folding groove 143 for accommodating the support rod 19; when the seat panel 14 is stowed, the support rod 19 can be stored within the folding groove 143. A guide block 20 is provided within the movable groove 1113, which slidably engages with the guide block 20. The lower end of the support rod 19 is hingedly connected to the guide block 20. For example, guide grooves are provided on the two opposing side walls of the movable groove 1113, and the two ends of the guide block 20 are slidably connected within the guide grooves.

[0052] The above is only a specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in this application should be covered by the scope of protection of the present application.
