Description

Technical Field

[0001] This utility model relates to the field of express delivery receiving box technology, and more specifically, to a roll-up rainproof receiving box. Background Technology

[0002] With the rapid development of automated logistics and unmanned delivery technologies, the demand for automated receiving of goods at the point of sale is increasing daily. Whether it's drone airdrops, automated delivery vehicle unloading, or other forms of unmanned handover scenarios, the core requirement is that receiving points can automatically, safely, and reliably complete the receiving and temporary storage of goods with minimal human intervention or no human involvement. For many commodities, especially those with specific requirements for warehousing environments, effectively protecting them from environmental factors such as rain and dew during the "outdoor exposure period" from receipt to pickup, and preventing moisture damage, has become a common and critical technical challenge. Taking cigarette delivery as an example, the product is extremely sensitive to humidity; moisture on the outer packaging directly affects its quality and commercial value. However, this problem also exists in the automated delivery processes of high-value or highly sensitive goods such as precision instrument parts, paper documents, and certain pharmaceuticals.

[0003] Currently, most devices or solutions for outdoor unmanned receiving points focus on achieving "accurate receiving," such as through visual guidance, increasing the receiving area, or using buffer structures to support the goods. However, they lack systematic and reliable designs for "immediate protection" after receiving, especially targeted moisture protection. Existing technologies typically have the following shortcomings: The protection mechanism is passive and has blind spots: a common practice is to set up a box with a simple top cover. This top cover is either always open or relies on a separate weather sensor (such as a rain sensor) to close after detecting rainfall. The former offers no protection at all; the latter has a significant response delay and time window—from the start of rainfall to the sensor triggering, and then to the actuator completing the closing action, the goods are already at risk of getting wet. More importantly, the top cover must be open the moment the goods are placed into the box. During the time from when the goods fall in to when the top cover closes, the top of the device is completely open, allowing wind and rain to directly intrude. This inherent "action gap" makes it impossible to achieve seamless protection during the delivery process.

[0004] Therefore, there is an urgent need for an innovative receiving device design that can both receive and protect goods. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a roll-up rainproof receiving box that can take into account both receiving and protecting goods.

[0006] To achieve the above objectives, the present invention provides a rainproof receiving box for roller shutters, comprising: External fixation bracket; An inner placement box is placed inside the outer fixing bracket, and the top of the inner placement box has an opening; A roller shutter, which is installed on the top of an external fixed bracket and is equipped with a rainproof curtain; A guide rail is fixed to the top of the outer fixed bracket, and the rainproof curtain is slidably connected to the guide rail, so that the rainproof curtain can be unfolded along the guide rail to cover the top opening of the inner placement box. A control module, which is electrically connected to the roller shutter.

[0007] In this technical solution, the rainproof curtain is automatically extended and retracted through the coordinated design of the roller shutter and guide rail, and the control module realizes the control of the rainproof curtain. During delivery, the roller shutter is driven by the internal motor to retract, exposing the opening of the inner storage box. After delivery, the rainproof curtain is automatically extended to cover the top opening of the entire inner storage box, effectively blocking rainwater and preventing the goods from getting damp. The roller shutter uses high-density waterproof fabric, and together with the guide rails symmetrically fixed to the top of the external fixed bracket, a sliding sealing structure is formed to reduce the risk of rainwater seeping from the edges. It can not only facilitate the delivery of goods, but also protect the temporarily stored goods.

A spring is disposed inside the connecting block, one end of which is connected to the sliding plate and the other end of which is connected to the connecting block. The spring is used to apply a spring force to the sliding plate to make the limiting block engage with the side slot.

[0009] As a preferred embodiment, the top of the limiting block has a first inclined surface, and the bottom of the side fixing block has a second inclined surface. When the inner placement box is placed into the outer fixing bracket, the second inclined surface contacts and engages with the first inclined surface.

[0010] As a preferred embodiment, the system also includes a pull rod, which is fixed to one side of the sliding plate and slidably connected to the connecting block.

[0015] As a preferred embodiment, it also includes multiple inner limiting brackets, which are bolted to the inside of the outer fixed bracket to limit the inner placement box in the horizontal direction.

[0016] As a preferred embodiment, the system also includes multiple support bases symmetrically arranged at the bottom of the external fixing bracket, with a base pad at the bottom of each support base.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes the coordinated design of the roller shutter and guide rail, and through the control module, enables the roller shutter to quickly respond to the delivery command to retract the rainproof curtain. After delivery, the roller shutter is controlled to immediately unfold the rainproof curtain to prevent rainwater from entering. The sliding sealing structure between the rainproof curtain and the guide rail further enhances the edge waterproofing effect, effectively ensuring that the goods are not damp during temporary storage.

[0018] 2. The inclined surface allows for quick snap-fit ​​and fixation of the inner box without the need for additional tools, making loading and unloading efficient; the spring continuously provides locking force to ensure that the inner box remains stable and does not loosen in outdoor environments, while the pull rod design makes it easy to unlock manually, making operation simple.

[0019] 3. The combination of the lifting platform and buffer pad inside the box can adapt to the weight of the goods and adjust the height accordingly. At the same time, it absorbs the impact of delivery and avoids damage to delicate or fragile goods. It is especially suitable for fragile items such as cigarettes.

[0020] 4. The inner limit bracket and auxiliary positioning mechanism are used to accurately position and fix the inner box in multiple dimensions to prevent displacement; the support base with base pad improves the adaptability of the device to different ground surfaces and has anti-slip and shock absorption functions to ensure stable outdoor placement.

[0026] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example 1: like Figure 1-5 As shown, this embodiment provides a rainproof receiver box for roller shutters, comprising: External fixation bracket 1; An inner placement box 6 is placed inside the outer fixing bracket 1, and the top of the inner placement box 6 is provided with an opening; Roller blind 19, which is installed on the top of the external fixed bracket 1, and a rainproof curtain 12 is provided on the roller blind 19; The guide rail 20 is fixed to the top of the outer fixed bracket 1, and the rainproof curtain 12 is slidably connected to the guide rail 20, so that the rainproof curtain 12 can be unfolded along the guide rail 20 to cover the top opening of the inner placement box 6. The control module is electrically connected to the roller shutter 19. The control module receives commands from a mobile app or a drone via 4G signal to remotely control the roller shutter 19, driving the motor inside to retract the rainproof curtain 12 along the guide rail 20, exposing the top opening. After delivery, the motor reverses direction, automatically unfolding the curtain to cover the top of the housing, effectively blocking rainwater and reducing the risk of edge seepage.

[0027] In this embodiment, the external fixation bracket 1 is a frame structure, and the interior of the external fixation bracket 1 has space for accommodating the inner box 6.

[0028] Specifically, it also includes a housing locking mechanism, which includes: Side fixing block 9, which is fixed to the outside of the inner placement box 6, and a side slot 10 is provided on the outside of the side fixing block 9; Connecting block 11, wherein the connecting block 11 is disposed inside the external fixing bracket 1; Sliding plate 17, the sliding plate 17 being slidably disposed inside the connecting block 11; Limiting blocks 14, two of the limiting blocks 14 are symmetrically fixed to one side of the sliding plate 17 and slidably connected to the connecting block 11. The limiting blocks 14 are used to cooperate with the side slot 10. Spring 16 is disposed inside the connecting block 11. One end of spring 16 is connected to the sliding plate 17 and the other end is connected to the connecting block 11. Spring 16 is used to apply a spring force to the sliding plate 17 to make the limiting block 14 engage with the side slot 10.

[0029] It also includes a pull rod 13, which is fixed to one side of the sliding plate 17 and slidably connected to the connecting block 11.

[0030] Specifically, the top of the limiting block 14 has a first inclined surface 15, and the bottom of the side fixing block 9 has a second inclined surface 18. When the inner placement box 6 is placed into the outer fixing bracket 1, the second inclined surface 18 contacts and engages with the first inclined surface 15.

[0031] In this embodiment, when the inner box 6 is placed in the outer fixed bracket 1, the limiting block 14 slides into the side slot 10 under the guidance of the first inclined surface 15 and the second inclined surface 18, thereby positioning the inner box 6 and the outer fixed bracket 1. When the inner box 6 needs to be removed, the sliding plate 17 is driven by the pull rod 13 to slide the limiting block 14 outward, so that the limiting block 14 disengages from the side slot 10, and the locking mechanism is unlocked.

[0032] Specifically, it also includes a side fixing plate 2, which is welded and fixed at equal intervals to the bottom of the outer fixing bracket 1 to support the inner placement box 6.

[0033] Specifically, it also includes multiple inner limit stops 3, which are bolted to the inner side of the outer fixed bracket 1 to limit the inner placement box 6 in the horizontal direction.

[0034] In this embodiment, multiple inner limiting brackets 3 restrict the horizontal swaying of the inner box 6 from all sides, especially preventing the box from shifting due to airflow disturbance during delivery.

[0035] Specifically, it also includes multiple support bases 4, which are symmetrically arranged at the bottom of the external fixed bracket 1, and a base pad 5 is provided at the bottom of the support base 4.
