Description

Technical Field

[0001] This invention relates to the field of centralized management and charging technology for examination equipment, specifically to a centralized charging and management system for examination tablet computers. Background Technology

[0002] With the increasing prevalence of paperless and computer-based testing, exam tablets typically need to be charged and distributed centrally before the exam, and collected, counted, and transported centrally after the exam. To improve management efficiency, exam tablets generally need to be placed in groups in storage or charging equipment and kept in relatively stable positions for easy relocation and recharging later.

[0003] Existing centralized charging cabinets or storage boxes provide locations for insertion and power supply, but they typically lack effective linkage between lid opening and closing, device fixation, and power supply status. Administrators may still need to manually tighten or inspect the device before closing the lid, and then release the fixation before opening the lid to retrieve it. Therefore, how to automatically secure the tablet computer when the lid is closed and automatically release it when the lid is opened for retrieval is a problem that requires further improvement for this type of centralized charging and management equipment. Summary of the Invention

[0004] This invention provides a centralized charging and management system for examination tablet computers, which addresses the shortcomings of existing centralized storage and charging devices for examination tablet computers in terms of automatic fixing when the cover is closed, automatic release when the cover is opened, and centralized charging management.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a centralized charging and management system for examination tablet computers, including a housing and a cover connected to the housing for opening and closing. The housing has a storage space for accommodating multiple examination tablet computers. The housing is provided with a limiting component for separating and limiting the examination tablet computers. The bottom of the housing is provided with a charging area corresponding to the charging interface of the examination tablet computer. A locking component for locking the cover is provided between the cover and the housing.

[0006] The limiting component includes multiple sets of limiting teeth arranged along the arrangement direction, and the adjacent limiting teeth form a limiting space adapted to the thickness direction of the examination tablet computer, so that multiple examination tablet computers can be placed at intervals in a vertical or near-vertical posture; the charging area includes multiple charging connectors arranged corresponding to the limiting space, so that the examination tablet computer can be connected to the corresponding charging connector after being inserted into the corresponding limiting space.

[0007] The locking assembly includes a mounting base, a lever, and a locking ring. The cover has a mounting part and a slot that can cooperate with the locking ring. After the locking ring is engaged in the slot, the lever can be moved to lock the locking ring and the mounting part, thereby restricting the cover to the closed state.

[0008] Furthermore, the system also includes a stabilizing component, which includes a stabilizing seat arranged opposite to each other, and the stabilizing seat is provided with a clamping groove corresponding to the side of the examination tablet computer; when the stabilizing seats move closer to each other or swing inward, the clamping groove can provide lateral restraint for the examination tablet computer, thereby reducing the shaking of the tablet computer during transportation or stacking.

[0009] Furthermore, the system also includes a transmission system that is linked to the opening and closing action of the cover. The transmission system can convert the rotational motion of the cover when it is closed into the linear motion and lifting motion of the drive component, and drive the stabilizing seat to swing through the drive arm, so that the stabilizing seat automatically establishes a clamping state during the closing process of the cover and automatically releases the clamping state during the opening process of the cover.

[0010] In one specific structure, the transmission system includes a hinge shaft linked to the cover, a first gear mounted on the hinge shaft, a second gear meshing with the first gear, a drive shaft, a reel, a guide wheel, a pull rope, a first drive member, a second drive member, and a reset spring. When the cover is closed, the first gear drives the drive shaft and the reel to rotate via the second gear. The reel winds up the pull rope, which pulls the first drive member to move, and the first drive member then pushes the second drive member upward.

[0011] A driving part is provided between the first driving member and the second driving member to cooperate with each other. The driving part can adopt a strip-shaped protrusion with a guide slope or a slope cooperation structure, thereby converting the lateral movement of the first driving member into the upward movement of the second driving member. The second driving member cooperates with the transmission part of the stabilizing seat through the driving arm, so that the stabilizing seat rotates around the shaft and forms a clamp.

[0012] The stabilizer can also work with a torsion spring. The torsion spring stores energy when the stabilizer is holding the tablet and drives the stabilizer to reset when the cover is opened and the second drive component moves down, so that the tablet computer can be smoothly removed after the cover is opened.

[0013] Furthermore, the system is equipped with electrode plates related to the power supply circuit of the charging area, and the contact state of the electrode plates is coordinated with the closed position of the second driving component; when the cover is closed and drives the second driving component to a predetermined position, the power supply circuit of the charging area is turned on, and when the cover is opened and the second driving component is reset, the power supply circuit is turned off.

[0014] Furthermore, a handle is provided on the outside of the box to facilitate overall transport after the lid is locked; a protrusion is provided on the bottom of the box and a recess is provided on the lid. The protrusion can cooperate with the recess of another system, so that multiple systems can be stably stacked and stored.

[0015] The beneficial effects of this invention include at least the following: the system can centrally complete the storage, limiting, charging, locking and overall transportation of multiple examination tablets in the same box, reducing the workload of sorting and inspecting each tablet individually; the closing action of the lid can simultaneously drive the stabilizing component to clamp the examination tablet, improving the stability during transportation and stacking; the opening action of the lid can simultaneously release the clamp and cut off the power supply, improving the convenience of picking up and putting down and the safety of power management.

[0016] This invention also uses gears, reels, ropes, driving components, and elastic reset components to form a mechanical linkage, avoiding the need for a separate complex electronically controlled clamping mechanism. The structure is more intuitive, the sequence of actions is clear, and it is easy to manufacture, assemble, and maintain. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0021] Example 1 This embodiment provides a centralized charging and management system for examination tablet computers. For example... Figures 1 to 3 , Figure 13 and Figure 14 As shown, the system is used to centrally collect, charge, transport, and stack multiple examination tablets 10 to adapt to management scenarios such as examination room setup, pre-examination distribution, and post-examination collection.

[0022] The system includes a housing 1 and a cover 2 that can be opened or closed relative to the housing 1. The housing 1 forms an enclosure structure with an opening at the top, and the cover 2 covers the opening of the housing 1 and is hinged to the housing 1. When the cover 2 is closed, the housing 1 and the cover 2 together form a relatively enclosed space for accommodating the examination tablet computer 10, thereby reducing external collisions and dust entry.

[0023] The housing 1 is equipped with a limiting component 4. The limiting component 4 can be arranged in a row along the length or width of the housing 1. The limiting component 4 includes multiple limiting teeth 41 arranged side by side, and a limiting space is formed between two adjacent limiting teeth 41 to accommodate the edge of the examination tablet computer 10. After the examination tablet computer 10 is inserted into the limiting space, its thickness direction is constrained by the limiting teeth 41. Therefore, multiple examination tablet computers 10 can be arranged neatly at intervals to avoid direct friction between adjacent devices.

[0024] The bottom of the housing 1 is provided with a charging area 5, which includes multiple charging connectors 51. These multiple charging connectors 51 correspond to multiple limiting spaces formed by the limiting component 4, ensuring that when the examination tablet computer 10 is inserted downwards along the direction defined by the limiting teeth 41, its charging interface can align and connect with the corresponding charging connector 51. The charging area 5 can be electrically connected to the built-in battery of the housing 1 or to an external power source, thereby providing centralized power to multiple examination tablet computers 10.

[0025] In the above structure, the limiting teeth 41 separate the thickness direction of the examination tablet computer 10, and the charging connector 51 positions the bottom interface of the examination tablet computer 10. The two cooperate with each other so that when the examination tablet computer 10 is inserted, it is first guided by the limiting teeth 41 and then mates with the charging connector 51. This can reduce interface wear caused by tilting the tablet computer during insertion, and maintain a more consistent insertion depth when multiple examination tablet computers 10 are placed in batches, thereby improving the reliability of centralized charging.

[0026] A locking assembly 3 is provided between the cover 2 and the housing 1. The locking assembly 3 includes a mounting base 31 fixed to the outside of the housing 1, a lever 32 rotatably connected to the mounting base 31, and a locking ring 33 rotatably connected to the lever 32. The cover 2 is provided with a mounting part 21, which has a slot 211 for the locking ring 33 to partially enter. After the locking ring 33 is engaged in the slot 211, the lever 32 is pushed down, and a tension relationship is formed between the locking ring 33 and the mounting part 21, thereby restricting the opening of the cover 2 relative to the housing 1.

[0027] The mounting base 31, the lever 32, and the locking ring 33 form an operation similar to over-center locking. When the lever 32 is rotated to the locked position, the locking ring 33 applies a downward holding force to the mounting part 21, reliably pressing the cover 2 against the box body 1. To open, the lever 32 is lifted upwards to release the tension between the locking ring 33 and the mounting part 21. Then, the locking ring 33 is removed from the slot 211, allowing the cover 2 to be opened. This structure allows managers to quickly confirm whether the cover 2 is locked after storage.

[0028] The case 1 is also equipped with a handle 6. After the locking assembly 3 locks the case 1 and the cover 2, the management personnel can lift or transfer the entire system through the handle 6, avoiding direct contact with the examination tablet computer 10 inside the case 1. The bottom of the case 1 is provided with a protrusion 13, and the upper surface of the cover 2 is provided with a recess 24; when multiple systems are stacked, the recess 24 of the lower system can receive the protrusion 13 of the upper system, thereby limiting the relative sliding of the upper and lower cases and improving the stability of centralized storage.

[0029] In Embodiment 1, a transfer and stacking mechanism is formed through the locking assembly 3, handle 6, protrusion 13, and recess 24: the locking assembly 3 prevents the cover 2 from accidentally opening during transport, the handle 6 facilitates lifting as a whole, and the protrusion 13 and recess 24 provide restraint when stacked vertically. This mechanism eliminates the need for a separate transport tray during batch transfers before and after exams, reducing the risk of the box 1 sliding, the cover 2 loosening, and the internal exam tablet computer 10 being bumped.

[0030] Example 2 This embodiment further includes a stabilizing component 7 and a transmission system 8, based on Embodiment 1. For example... Figures 4 to 12As shown, the stabilizing component 7 is used to further clamp the examination tablet computer 10 after the cover 2 is closed, and the transmission system 8 is used to transmit the opening and closing action of the cover 2 to the stabilizing component 7, so that the clamping and releasing actions are consistent with the state of the cover 2. The main problem solved by this embodiment is that: after the examination tablet computer 10 is inserted into the limiting component 4 and the charging area 5, if it still needs to be manually fixed one by one, it will increase the storage steps and make it easy to miss some; if the clamping structure remains fixed after the cover is opened, it will affect the removal of the examination tablet computer 10. Therefore, this embodiment automatically forms a fixation when the cover 2 is closed and automatically releases the fixation when the cover 2 is opened, so as to facilitate retrieval.

[0031] The stabilizing assembly 7 includes two sets of opposing stabilizing seats 71. Each set of stabilizing seats 71 may include multiple stabilizing seats 71. The two sets of stabilizing seats 71 are respectively disposed on the inner wall of the housing 1 and located on both sides of the area where the examination tablet computer 10 is arranged, and respectively correspond to the limiting assemblies 4 distributed on both sides. The side of the stabilizing seat 71 facing the examination tablet computer 10 is provided with multiple clamping grooves 711, and the position of the clamping grooves 711 corresponds to the limiting space defined by the limiting teeth 41. When the two stabilizing seats 71 swing inward or move closer to each other, the clamping grooves 711 can contact or be adjacent to the side of the tablet computer, thereby reducing the lateral clearance of the examination tablet computer 10 and forming a clamping space together with the limiting teeth 41.

[0032] The stabilizing base 71 is rotatably connected to the housing 1 via a first shaft 72, which provides a pivot point for the stabilizing base 71. A second shaft 73 is located below or near the stabilizing base 71, and a torsion spring 74 is mounted on the second shaft 73. One end of the torsion spring 74 engages with the stabilizing base 71 or its transmission part 712, and the other end engages with the housing 1 or a fixed structure near the second shaft 73. When the stabilizing base 71 is driven to the clamping position, the torsion spring 74 undergoes elastic deformation and stores reset energy.

[0033] A transmission part 712 is provided on the side of the stabilizing seat 71 near the transmission system 8. The transmission part 712 can be an arc-shaped or cam-shaped force-receiving part. One side of the transmission part 712 is used to receive the thrust applied by the drive arm 872, and the other side cooperates with the torsion spring 74 so that when the drive arm 872 rises, it can push the stabilizing seat 71 to rotate around the first axis 72 in the clamping direction; after the drive arm 872 falls, the torsion spring 74 can drive the stabilizing seat 71 to return to the release direction.

[0034] When the transmission part 712 adopts an arc-shaped or cam-shaped force-bearing part, the thrust of the drive arm 872 on the transmission part 712 can be converted into the swing force of the stabilizing seat 71 around the first axis 72. Since the torsion spring 74 is loaded during the clamping process, the stabilizing seat 71 can maintain a stable position on the examination tablet computer 10 when the cover is closed, and can also move away from the side of the examination tablet computer 10 by the restoring force of the torsion spring 74 after the cover is opened, thus taking into account both the convenience of transportation and fixation and the ease of picking up and putting down.

[0035] The transmission system 8 includes a drive shaft 81, two pulleys 82, two first guide pulleys 83, two second guide pulleys 84, two pull ropes 85, a first drive component 86, a second drive component 87, and a tension spring 88. A transmission cavity 11 is formed on the housing 1, and the drive shaft 81 is rotatably mounted within the transmission cavity 11. A hinge shaft 22 is fixedly connected to the cover 2, and the hinge shaft 22 is rotatably connected to the housing 1, forming a hinged connection between the cover 2 and the housing 1. Two first gears 23 are provided on the hinge shaft 22, and two second gears 811 are provided on the drive shaft 81. The two first gears 23 are respectively meshed with the two second gears 811.

[0036] When the cover 2 rotates relative to the box 1, the hinge shaft 22 rotates synchronously with the cover 2. The two first gears 23 drive the two second gears 811 to rotate through their meshing relationship. The two second gears 811 then drive the transmission shaft 81 to rotate. The two spools 82 are fixedly installed on the transmission shaft 81. Therefore, when the transmission shaft 81 rotates, the two spools 82 rotate synchronously, realizing the synchronous winding or unwinding of the two pull ropes 85, making the force on the first drive member 86 more balanced.

[0037] The bottom wall of the housing 1 has an internal cavity 12, in which the first driving member 86 is slidably installed. The side wall of the housing 1 has a notch for the pull rope 85 to pass through, and the side wall of the cavity 12 also has a notch for the pull rope 85 to pass through. Two first guide wheels 83 are rotatably mounted at the notches on the side walls of the housing 1, and two second guide wheels 84 are installed inside the cavity 12. One end of each pull rope 85 is connected to the corresponding reel 82, and the other end passes over the corresponding first guide wheel 83 and second guide wheel 84 before being fixedly connected to the first driving member 86. This changes the direction of force on the pull rope 85 and reduces friction through the guide wheels.

[0038] When the two pull ropes 85, the two first guide wheels 83, and the two second guide wheels 84 are respectively arranged on both sides of the transmission system 8, the traction force on the first drive member 86 is closer to a balanced state, which can reduce jamming or uneven wear caused by unilateral force. The first guide wheels 83 and the second guide wheels 84 steer and support the pull ropes 85, so that the rotational stroke of the cover 2 can be stably converted into the linear stroke of the first drive member 86 in the receiving cavity 12, thereby improving the repeatability and reliability of the cover clamping action.

[0039] From the perspective of force and displacement transmission, the angular displacement of the cover 2 is first converted into the rotation of the first gear 23 through the hinge shaft 22. After the first gear 23 meshes with the second gear 811, the transmission shaft 81 rotates synchronously. The reel 82 winds up the pull rope 85 along with the transmission shaft 81, forming a stable linear traction. The first guide wheel 83 and the second guide wheel 84 not only change the traction direction of the pull rope 85, but also ensure that the pull rope 85 maintains a smooth transition relative to the side wall of the box 1 and the receiving cavity 12, thereby reducing the uneven wear and jamming of the pull rope 85 during repeated opening and closing.

[0040] The side of the first driving member 86 away from the pull rope 85 is connected to the tension spring 88, and the other end of the tension spring 88 is connected to the inner wall of the receiving cavity 12 or the fixed part of the box 1. When the cover 2 is closed, the reel 82 winds up the pull rope 85, and the pull rope 85 pulls the first driving member 86 to slide in the first direction, and the tension spring 88 is stretched and stores energy; when the cover 2 is opened, the reel 82 releases the pull rope 85, the tension spring 88 releases its elastic force and drives the first driving member 86 to return to its original position in the opposite direction.

[0041] A first driving member 86 is provided with a first driving part 861, which is a strip-shaped protrusion and has a guide slope for transmitting driving force; a second driving member 87 is provided with a second driving part 871, which is also a strip-shaped protrusion and has a guide slope that matches the first driving part 861. When the first driving member 86 moves laterally, the guide slope of the first driving part 861 pushes against the guide slope of the second driving part 871, thereby converting the lateral displacement of the first driving member 86 into the upward displacement of the second driving member 87.

[0042] The second driving member 87 is provided with two driving arms 872, which extend from the top wall of the receiving cavity 12 and are slidably connected to the top wall of the receiving cavity 12 or the guide structure inside the housing 1. The two driving arms 872 guide and limit the second driving member 87, so that the second driving member 87 moves only in the vertical direction under the cooperation of the first driving part 861 and the second driving part 871. The upper end of the driving arm 872 corresponds to the transmission part 712 of the stabilizing seat 71. Therefore, when the second driving member 87 rises, the driving arm 872 can push the transmission part 712 and drive the stabilizing seat 71 to swing around the first axis 72 in the clamping direction.

[0043] The guide ramps of the first drive unit 861 and the second drive unit 871 form a wedge-shaped force transmission pair. The lateral thrust of the first drive member 86 is decomposed along the ramp into a component force that pushes the second drive member 87 upward. After the second drive member 87 rises, the drive arm 872 applies a thrust to the transmission part 712 of the stabilizing seat 71. This thrust forms a torque in the clamping direction relative to the first shaft 72, causing the stabilizing seat 71 to swing to the side of the examination tablet computer 10. At the same time, the torsion spring 74 is loaded and stores reset energy, which is used to drive the stabilizing seat 71 to quickly leave the clamping position when the cover is opened.

[0044] During the closing process of the cover 2, the cover 2 sequentially drives the hinge shaft 22, the first gear 23, the second gear 811, the transmission shaft 81, and the reel 82. The reel 82 winds up the pull rope 85, which pulls the first driving member 86 to slide in the first direction. At the same time, the tension spring 88 is stretched and stores energy. The first driving member 86 pushes the second driving member 87 upward via the first driving part 861 and the second driving part 871. The second driving member 87 then pushes the transmission part 712 through the driving arm 872, causing the two side stabilizing seats 71 to swing towards the examination tablet computer 10. Thus, the closer the cover 2 is to the closed position, the more stable the stabilizing seats 71 are in limiting the examination tablet computer 10, until the cover 2 forms an automatically fixed state when closed.

[0045] In other words, this embodiment does not rely solely on manually pressing the examination tablet computer 10, but rather uses the closing action of the cover 2 as the trigger action for the clamping action. After the administrator completes the placement and closes the cover 2, the transmission system 8 automatically clamps the stabilizing seat 71, so that the examination tablet computer 10 is jointly constrained by the limiting teeth 41, the charging connector 51, and the clamping groove 711 in the locked state of the cover 2, reducing loosening caused by transport vibration and helping to maintain stable contact between the charging interface and the charging connector 51.

[0046] When the cover 2 is fully closed and locked by the locking assembly 3, the stabilizing seat 71 is in a clamping or stabilizing state. The clamping groove 711 engages with the side of the examination tablet computer 10, and the limiting teeth 41 of the limiting assembly 4 and the charging connector 51 of the charging area 5 together maintain the position and insertion state of the tablet computer. This clamping action is automatically established by the closing action of the cover 2, eliminating the need for personnel to first fix the examination tablet computer 10 and then close the cover 2, avoiding the two-step operation of "fixing first and then closing the cover", reducing the risk of missed clamping, insufficient clamping, or improper insertion, and improving the operational efficiency and fixing reliability during batch storage.

[0047] When the cover 2 is opened, the cover 2 drives the first gear 23 and the second gear 811 to move in opposite directions. The pull rope 85 is released by the pull wheel 82, and the restoring force of the tension spring 88 pulls the first driving member 86 to reset. The upward pushing action of the first driving part 861 on the second driving part 871 is released. At the same time, the torsion spring 74 releases energy and drives the stabilizing seat 71 to rotate in the release direction. The transmission part 712 causes the second driving member 87 to move down and reset through the driving arm 872. At this time, the stabilizing seats 71 on both sides release their clamping or stabilizing contact with the examination tablet computer 10, realizing automatic release of fixation when the cover 2 is opened. The management personnel can take out the examination tablet computer 10 without additional removal of the clamps.

[0048] During the opening and release process described above, the tension spring 88 is mainly used to return the first driving member 86 to its initial position, and the torsion spring 74 is mainly used to return the stabilizing seat 71 to its release position. These two springs act on different positions of the transmission chain, preventing the stabilizing seat 71 from being passively pushed open solely by the tablet computer 10 being pulled out. Therefore, after the cover 2 is opened, the clamping groove 711 has moved away from or reduced its lateral constraint on the examination tablet computer 10, allowing administrators to directly remove the examination tablet computer 10 upwards, reducing the possibility of the interface being pulled laterally.

[0049] The system also includes electrode plates 9. Electrode plates 9 are disposed in the power supply circuit of the charging area 5 and cooperate with the closing stroke of the second drive member 87. When the second drive member 87 rises to the predetermined position as the cover 2 closes, the electrode plates 9 make the power supply circuit of the charging area 5 conductive, and the multiple charging connectors 51 can supply power to the examination tablet computer 10. When the cover 2 is opened and the second drive member 87 is reset, the electrode plates 9 separate from the corresponding contact position or disconnect the power supply circuit, thereby realizing power cut-off when the cover is opened, and stopping all examination tablet computers 10 from charging.

[0050] The lifting and lowering states of the electrode plate 9 and the second driving member 87 are coordinated to ensure that the power supply state corresponds to the mechanical state of the cover 2 and the stabilizing base 71. When the cover 2 is not closed in place, the second driving member 87 has not risen to the predetermined position, and the charging area 5 is not in a conducting charging state. After the cover 2 is closed in place and clamping is completed, the electrode plate 9 conducts the power supply circuit, so that the charging action occurs when the examination tablet computer 10 is fixed. After the cover 2 is opened, the second driving member 87 resets and disconnects the power supply circuit, which can reduce the risk of hot plugging and unplugging and accidental contact when opening and removing the cover.

[0051] The stroke coordination between the electrode plate 9 and the second drive member 87 creates a mechanical interlock between the power supply state and the clamping state. Only when the second drive member 87 rises to the predetermined position representing the closed position of the cover 2 and the clamping position of the stabilizing seat 71, does the electrode plate 9 connect the power supply circuit of the charging area 5. When the cover 2 is opened and the second drive member 87 is reset, the electrode plate 9 disengages from the contact or disconnects the circuit, so that the charging connector 51 is in a de-energized state before the examination tablet computer 10 is removed or placed, thereby reducing the risk of hot plugging and unplugging, accidental electrode contact, and continued power supply under interface misalignment.

[0052] In addition to the cover linkage transmission system 8 shown in the figure, the stabilizing seat 71 can also be driven by a drive structure that can generate linear displacement or swing displacement; however, in this embodiment, the stabilizing component 7 is driven by the opening and closing action of the cover 2, which not only reduces individual operation steps, but also makes the action relationship of "closing the cover, clamping, powering on" and "opening the cover, releasing, powering off" consistent, which is convenient for examination staff to perform batch management.

[0053] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
