Description

Technical Field

[0001] The present invention relates to the technical field of lockers, and in particular to a mobile locker used in campuses. Background Art

[0002] Campus mobile lockers are flexible storage solutions designed for campus scenarios. Their core value lies in solving the temporary storage needs of students' belongings, while taking into account space utilization and convenience. Through the "flexible deployment + intelligent management" model, they effectively solve the pain points of student belongings storage and provide data support for campus space management.

[0003] After searching, it was found that according to the invention patent with publication number CN113057454A, a mobile locker for use on campus is disclosed, which includes: a cabinet body, a movable plate, an adjustment device and a moving device. The cabinet body has a storage slot, the movable plate is movably arranged in the storage slot, and the adjustment device is driven and connected to the movable plate. Among them, the adjustment device includes a rotating component and a sliding component. The rotating component includes: an adjusting drum, a connecting rod, a driving wheel and a driven wheel; the adjusting drum is driven and connected to the driving wheel through the connecting rod, and the driving wheel and the driven wheel are connected by a traction rope. The sliding component includes: a guide base, a swing handle, a first pressure holding pin and a second pressure holding pin; the guide base has a sliding limit groove, the swing handle is arranged in the sliding limit groove through a reset elastic member, and the first pressure holding pin and the second pressure holding pin are arranged on the swing handle through a telescopic elastic member. Based on the movable structure, the internal layer height is adjustable. However, when this solution is actually used, the following shortcomings still exist:

[0004] Lockers, essential for students to store personal belongings, are often designed with multiple layers to maximize space utilization. However, in practice, this design creates a problem when students attempt to retrieve items from the lower locker. Due to the compact layout of the upper and lower lockers, the upper door protrudes slightly when opened. This can easily cause the user to bump their head against the upper door panel if they stand up or look up. This is especially true during peak locker usage periods, such as breaks, when students are frequently accessing items and their attention is distracted, significantly increasing the likelihood of accidental collisions.

[0005] Based on this, the present invention discloses a mobile locker for use on campus. Summary of the Invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This type of mobile locker is used in campuses. By setting an elastic sheet and a reel, when a student's head accidentally hits the anti-collision plate, the cooperation of the push sheet and the elastic sheet triggers the pawl to disengage from the ratchet, and the energy stored in the coil spring is instantly released to drive the reel to rotate, and the anti-collision plate is driven upward by the cable to quickly separate the collision part from the human body, eliminating the risk of continuous collision at the physical level, avoiding head injuries from collision, and playing an effective avoidance and protection role.

[0022] 2. This type of mobile locker is used in campuses. By setting up anti-collision airbags and buffer airbags, when the anti-collision plate is lifted, the piston plate slides directionally in the air guide box to form a positive pressure airflow, inflating the anti-collision airbag and the buffer airbag respectively. The former absorbs the impact kinetic energy of the secondary lifting of the head through elastic deformation, and the latter forms a reverse supporting force on the anti-collision plate, constructing a double protection barrier of "airbag buffering-structural support", reducing the collision damage value to a range that the human body can bear.

[0023] 3. This type of mobile locker is used in campuses. By setting a knocking rod and a knocking plate, the transmission gear rotates to drive the connecting rod mechanism to produce a mechanical knocking action. The knocking rod periodically knocks the sounding plate to form a regular warning sound. Combined with the visual feedback of the inflation of the anti-collision airbag, it strengthens students' risk avoidance awareness through both auditory and visual channels, effectively reducing the probability of secondary injuries caused by misjudgment of collision status.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] The present invention provides a mobile locker for campus use. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 10 As shown, it includes a component unit and an anti-collision unit;

[0038] Among them, the component unit includes a cabinet body 11, and self-locking wheels are provided at the four corners of the bottom surface of the cabinet body 11. A number of evenly distributed cabinet compartments 12 are provided on the side of the cabinet body 11. The inner walls of the cabinet compartments 12 are hinged with door panels 13. The bottom surface of the door panel 13 is provided with a slot 14. The inner wall of the slot 14 is slidably installed with an anti-collision plate 15. A limited slot 62 is provided on the side of the anti-collision plate 15. A limited plug-in plate 61 is fixedly installed on the inner wall of the cabinet compartment 12. The width of the limited slot 62 is at least greater than the width of the limited plug-in plate 61. The inner wall of the cabinet compartment 12 is provided with a sealing strip 63 corresponding to the anti-collision plate 15;

[0039] The anti-collision unit includes a shaft 21 rotatably mounted on the inner wall of the slot 14. Two winding discs 22 are fixedly mounted on the outer wall of the shaft 21. An air guide box 41 is fixedly mounted on the inner wall of the slot 14 below the shaft 21.

[0040] Among them, a limit assembly is provided on the shaft 21, and the limit assembly includes cables 23 respectively arranged on the inner sides of the two winding drums 22. The bottom ends of the two cables 23 are respectively fixedly mounted on the two ends of the top surface of the anti-collision plate 15 through fixing rings. A coil spring 24 is set on the shaft 21, and the two ends of the coil spring 24 are respectively fixedly connected to the shaft 21 and the slot 14. A ratchet 25 is fixedly set on the end of the shaft 21, and a rotating shaft 26 is rotatably mounted on the inner wall of the slot 14. A pawl 27 engaged with the ratchet 25 is fixedly set on the rotating shaft 26. A torsion spring 28 is set on the end of the rotating shaft 26, and the two ends of the torsion spring 28 are respectively fixedly connected to the rotating shaft 26 and the slot 14.

[0041] When the door panel 13 and the anti-collision plate 15 are opened, the limit plug 61 is separated from the limit slot 62, and the limit of the anti-collision plate 15 can be released.

[0042] See also Figure 7 、 Figure 8 As shown, the inner wall of the slot 14 is provided with a trigger assembly, which includes a guide groove 31 opened on the inner wall of the slot 14, and two elastic sheets 32 are slidably installed on the inner wall of the guide groove 31. An arc-shaped protrusion 33 is fixedly installed between the opposite ends of the two elastic sheets 32, and a top rod 34 is fixedly installed on the top of the upper elastic sheet 32 ​​of the two elastic sheets 32. A top moving sheet 35 corresponding to the elastic sheet 32 ​​is fixedly installed on the top surface of the anti-collision plate 15. The top moving sheet 35 is in the shape of a barb, and the side surface of the top moving sheet 35 opposite to the elastic sheet 32 ​​is set as an arc surface. The outer wall of the pawl 27 is fixedly installed with a connecting plate 36 corresponding to the top rod 34;

[0043] When the upper door panel 13 and the anti-collision plate 15 are in the open state, when the lower cabinet compartment 12 is used by a student to take an item and raise his body, if his head accidentally hits the anti-collision plate 15, his head will push the bottom surface of the anti-collision plate 15 to a certain extent. Since the pushing piece 35 is in the shape of a barb, and the side opposite to the elastic piece 32 is set to be arc-shaped, when the anti-collision plate 15 is initially pushed, the pushing piece 35 can move accordingly and drive the elastic piece 32 and the arc-shaped protrusion 33 to slide upward along the guide groove 31, thereby squeezing the connecting plate 36 through the push rod 34, so that the connecting plate 36 drives the pawl 27 and the rotating shaft 26 to rotate. When the pawl 27 rotates, it can separate from the ratchet 25, and the limit of the ratchet 25 can be released. 24 is in a compressed state, so when the ratchet 25 is released from the limit, the shaft 21 and the winding disk 22 can rotate quickly under the action of the coil spring 24, thereby pulling the anti-collision plate 15 through the cable 23, and when the anti-collision plate 15 moves upward under the action of the tension, the pushing piece 35 can be misaligned with the elastic piece 32 through the arc surface, and when the anti-collision plate 15 moves, it can squeeze the arc-shaped protrusion 33 between the two elastic pieces 32, so that the elastic pieces 32 at both ends can slide along the guide groove 31, so that the pushing rod 34 can always push the connecting plate 36, while keeping the pawl 27 and the ratchet 25 separated, ensuring that the anti-collision plate 15 can quickly rise and separate from the student's head, thereby achieving avoidance and preventing the student from being injured by excessive collision.

[0044] See also Figure 3 、 Figure 9 As shown, an air guide assembly is provided on the air guide box 41, which includes a drive screw 42 rotatably mounted on the inner wall of the air guide box 41, and one end of the drive screw 42 passes through the side of the air guide box 41. A piston plate 43 is slidably mounted on the inner wall of the air guide box 41, and the piston plate 43 is threadedly connected to the drive screw 42. A transmission gear 44 is fixedly mounted on the end of the drive screw 42 located outside the air guide box 41, and a fixed rack 45 meshing with the transmission gear 44 is fixedly mounted on the top surface of the anti-collision plate 15.

[0045] The air guide assembly also includes an anti-collision airbag 46 fixedly mounted on the bottom surface of the anti-collision plate 15. An air inlet pipe 47 is provided through the end of the air guide box 41 away from the transmission gear 44. A one-way valve is provided on the inner wall of the air inlet pipe 47. An air outlet pipe 48 is provided between the air guide box 41 and the anti-collision airbag 46. Two limit plates are symmetrically fixedly mounted on the inner wall of the slot 14. The bottom surfaces of the two limit plates are fixedly mounted with a cushioning airbag 49. The cushioning airbag 49 is connected to the air guide box 41 through a conduit 410.

[0046] During the process of the anti-collision plate 15 avoiding, the fixed rack 45 on its top surface can engage with the transmission gear 44 when it moves, and drive the transmission gear 44 and the drive screw 42 to rotate. When the transmission gear 44 rotates, the piston plate 43 is slidably installed on the inner wall of the air guide box 41 and is screwed to the drive screw 42, so that the piston plate 43 can be driven to slide on the inner wall of the air guide box 41, thereby quickly guiding the gas in the air guide box 41 through the outlet pipe 48 and the conduit 410 to the anti-collision airbag 46 and the buffer airbag 49 respectively, so that the anti-collision airbag 46 expands, providing protection for the secondary impact caused by the student continuing to raise his head. At the same time, the buffer airbag 49 can push the anti-collision plate 15, ensuring that the anti-collision plate 15 can be buffered when it is hit by a secondary impact, further increasing the protection effect during the secondary impact.

[0047] See also Figure 9 As shown, a prompt assembly corresponding to the air guide assembly is provided on the inner side of the slot 14. The prompt assembly includes a connecting rod 51 fixedly mounted on the side of the transmission gear 44. A rotating seat 52 is fixedly mounted on the end of the connecting rod 51. Two protrusions 53 are symmetrically fixedly mounted on the outer wall of the rotating seat 52. A support rod 54 is fixedly mounted on the inner wall of the slot 14. A knock rod 55 is rotatably mounted on the end of the support rod 54. A knock plate 56 corresponding to the knock rod 55 is provided on the inner wall of the slot 14.

[0048] When the transmission gear 44 rotates, the connecting rod 51 and the rotating seat 52 can be driven to rotate. When the rotating seat 52 rotates, the knocking rod 55 at the end of the support rod 54 can be toggled through the protrusion 53, so that the knocking rod 55 can rotate along the support rod 54 and knock the knocking plate 56 through the top, thereby issuing a warning sound to remind students to pay attention and avoid secondary collisions. After use, the student can directly pull the anti-collision plate 15 downward to reset the anti-collision plate 15. During the reset of the anti-collision plate 15, the reel 22 can be Reverse and unwind the cable 23. After the anti-collision plate 15 is in place, the push plate 35 is also in place synchronously, the push rod 34 is separated from the connecting plate 36, and the pawl 27 locks the ratchet 25, and the car is ready again to continue to use the anti-collision function normally. The fixed rack 45 can drive the transmission gear 44 to reverse, so that the piston plate 43 is reset, and the gas in the buffer airbag 49 and the anti-collision airbag 46 is re-drawn into the air guide box 41, and the air inlet pipe 47 can be used as a supplementary air source to ensure that the gas in the air guide box 41 is always sufficient.

[0049] The working principle of the present invention is as follows:

[0050] When the door 13 and the anti-collision plate 15 are opened, the limiting plug 61 is separated from the limiting slot 62, and the limiting of the anti-collision plate 15 can be released.

[0051] When the upper door panel 13 and the anti-collision plate 15 are in the open state, when the lower cabinet compartment 12 is used by a student to take an item and raise his body, if his head accidentally hits the anti-collision plate 15, his head will push the bottom surface of the anti-collision plate 15 to a certain extent. Since the pushing piece 35 is in the shape of a barb, and the side opposite to the elastic piece 32 is set to be arc-shaped, when the anti-collision plate 15 is initially pushed, the pushing piece 35 can move accordingly and drive the elastic piece 32 and the arc-shaped protrusion 33 to slide upward along the guide groove 31, thereby squeezing the connecting plate 36 through the push rod 34, so that the connecting plate 36 drives the pawl 27 and the rotating shaft 26 to rotate. When the pawl 27 rotates, it can separate from the ratchet 25, and the limit of the ratchet 25 can be released. When the anti-collision plate 15 moves upward under the action of the tension force, the push-up piece 35 can be dislocated with the elastic piece 32 through the arc surface, and when the anti-collision plate 15 moves, the arc-shaped protrusion 33 between the two elastic pieces 32 can be squeezed, so that the elastic pieces 32 at both ends can slide along the guide groove 31, so that the push-up rod 34 can always push the connecting plate 36, while keeping the pawl 27 and the ratchet 25 separated, ensuring that the anti-collision plate 15 can quickly rise and separate from the student's head, thereby achieving avoidance and preventing the student from being injured by excessive collision;

[0052] During the process of the anti-collision plate 15 avoiding, the fixed rack 45 on its top surface can mesh with the transmission gear 44 when it moves, and drive the transmission gear 44 and the driving screw 42 to rotate. When the transmission gear 44 rotates, the piston plate 43 is slidably mounted on the inner wall of the air guide box 41 and is screwed with the driving screw 42, so that the piston plate 43 can be driven to slide on the inner wall of the air guide box 41, thereby quickly guiding the gas in the air guide box 41 through the air outlet pipe 48 and the conduit 410 to the anti-collision airbag 46 and the buffer airbag 49 respectively, so that the anti-collision airbag 46 expands, providing protection for the secondary impact caused by the student continuing to raise his head. At the same time, the buffer airbag 49 can push the anti-collision plate 15 to ensure that the anti-collision plate 15 can be buffered when it is hit by the secondary impact, thereby further increasing the protection effect during the secondary impact.

[0053] At the same time, during the rotation of the transmission gear 44, the connecting rod 51 and the rotating seat 52 can be driven to rotate. When the rotating seat 52 rotates, the knocking rod 55 at the end of the support rod 54 can be toggled through the protrusion 53, so that the knocking rod 55 can rotate along the support rod 54 and knock the knocking plate 56 through the top, thereby issuing a warning sound to remind students to pay attention and avoid secondary collisions. After use, the student can directly pull the anti-collision plate 15 downward to reset the anti-collision plate 15. During the reset of the anti-collision plate 15, the reel 22 can be Reverse and unwind the cable 23. After the anti-collision plate 15 is in place, the push plate 35 is also in place synchronously, the push rod 34 is separated from the connecting plate 36, and the pawl 27 locks the ratchet 25, and it is ready again and can continue to be used normally for anti-collision. The fixed rack 45 can drive the transmission gear 44 to reverse, so that the piston plate 43 is reset, and the gas in the buffer airbag 49 and the anti-collision airbag 46 is re-drawn into the air guide box 41, and the air inlet pipe 47 can be used as a supplementary air source to ensure that the gas in the air guide box 41 is always sufficient.
