Description

Technical Field

[0001] This utility model relates to the field of tool cart technology, specifically to a multi-functional tool cart. Background Technology

[0002] In fields such as equipment maintenance, manufacturing assembly, and on-site construction, tool carts are indispensable mobile work platforms for technicians. Traditional tool carts typically use simple drawers, compartments, or open designs to store tools, which have significant drawbacks. For example, the lack of effective tracking and access control for tool retrieval makes tools prone to loss, misplacement, or unauthorized access, leading to asset damage and management chaos. Furthermore, relying on manual counting of tool types and quantities is inefficient, error-prone, and makes it difficult to monitor tool status in real time.

[0003] In recent years, some smart toolboxes or tool cabinets have introduced radio frequency identification (RFID) technology, which automatically identifies and manages inventory by labeling tools and installing readers / writers inside the box / cabinet. However, these solutions are mainly used for centralized management in fixed locations, have relatively limited functionality, only offering inventory counting capabilities, and lack deep integration with mobile tool carts.

[0004] For example, modern maintenance and testing work increasingly relies on electronic devices such as power tools, portable testing instruments (e.g., oscilloscopes, multimeters), laptops, and lighting equipment, all of which require a continuous and stable power supply. However, some outdoor or remote workplaces often lack readily available fixed power outlets, forcing technicians to carry bulky power banks or search for extension cords. This not only increases their burden but also poses risks such as tripping over cables, insufficient power outlets, and unstable voltage, severely impacting work efficiency and ease of operation.

[0005] During maintenance and testing, technicians often need to operate multiple devices simultaneously, consult documents (such as drawings or manuals on a computer), place components under test, or use testing probes. Traditional tool carts are primarily designed for tool storage, with limited overhead space and typically no expandability. When it's necessary to operate a laptop, place testing instruments, or temporarily store components, technicians often need to find additional workbenches, chairs, or other unstable supports, resulting in a cluttered workspace, inconvenient operation, and even potential damage from falling equipment.

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0044] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] like Figure 1 and Figure 2As shown, this utility model provides a multi-functional tool cart, including a toolbox 1. The toolbox 1 has several drawer boxes 2 installed inside, which are arranged vertically at intervals. Each drawer box 2 is slidably connected to a drawer 3. Each drawer 3 is an independent space that does not interfere with each other. Various tools can be placed inside the drawer 3. Each tool is bound with an electronic tag. At the same time, several ultra-high frequency radio frequency antennas 4 are installed inside each drawer box 2. When the drawer 3 is closed, the ultra-high frequency radio frequency antennas 4 can automatically inventory the tools in the drawer 3 through radio frequency identification technology and monitor the tool's position status in real time.

[0046] To prevent radio frequency signal leakage or ingress, a shielding strip 5 is affixed to the gap between drawer box 2 and drawer 3. The shielding strip 5 can be made of shielding materials such as conductive foam padding. Meanwhile, the toolbox 1, drawer box 2, and drawer 3 are made of metal, which allows the conductive foam padding to exert good shielding performance and ensure the identification accuracy of the ultra-high frequency radio frequency antenna 4.

[0047] Meanwhile, each drawer 3 is connected to a locking unit 6, and the toolbox 1 is also equipped with a control system 7. The control system 7 is electrically connected to each locking unit 6 and the ultra-high frequency radio frequency antenna 4. The radio frequency signal data identified by the ultra-high frequency radio frequency antenna 4 will be uploaded to the control system 7 in real time. At the same time, the control system 7 can control the opening and closing of the locking units 6. Only users authorized by the control system 7 can open the toolbox 1. The control system 7 can also automatically record storage and retrieval information, replacing the inefficient and error-prone manual counting, and significantly improving the efficiency of inventory management.

[0048] Preferably, the toolbox 1 in this embodiment is equipped with a large-capacity mobile power supply 9 inside, and several power sockets 10 are installed on the outside of the toolbox 1. The power sockets 10 are electrically connected to the mobile power supply 9, and the power sockets 10 have multiple output types, including AC, DC, USB, etc., which can power electronic devices such as power tools, testing instruments, and computers without the need for external power supply or extension cords, ensuring that the maintenance process can be carried out continuously and efficiently. It is especially suitable for power shortage scenarios such as outdoors and remote workshops.

[0049] Meanwhile, a temporary storage box 12 is installed on the side of the toolbox 1 away from the workbench 11. The temporary storage box 12 can provide temporary storage space for users. When users need to use multiple tools at the same time, some tools can be temporarily placed in the temporary storage box 12 to reduce the clutter of tools on site and maintain a clean and orderly working environment. The bottom of the toolbox 1 is equipped with universal casters 13, and a push handle 14 is also installed on one side of the toolbox 1. When in use, users can push the toolbox 1 to move it.

[0050] like Figure 3As shown, to facilitate the placement of computers, testing equipment, or components under test by users, a workbench 11 is hinged to one side of the top of the toolbox 1 in this embodiment. The workbench 11 has two states: unfolded and folded. When the user needs to use the workbench 11, the workbench 11 can be unfolded to quickly expand the top space of the toolbox 1. At this time, the workbench 11 is parallel to the top surface of the toolbox 1, providing a stable platform for placing computers, testing equipment, components under test, etc. After use, the user can fold the workbench 11. At this time, the workbench 11 is parallel to the side of the toolbox 1, thereby reducing the overall space occupied by the equipment and making the structure more compact.

[0051] Specifically, the workbench 11 includes two first support plates 111 spaced apart on one side of the toolbox 1. A second support plate 112 is hinged to the top of the first support plate 111, and the second support plate 112 can rotate around the first support plate 111. The second support plate 112 has an elongated sliding hole 114 extending along the length of the second support plate 112. A third support plate 113 is also hinged to the first support plate 111. The end of the third support plate 113 away from the first support plate 111 is slidably connected to the elongated sliding hole 114 of the second support plate 112. A placement plate 115 is installed on the top of the two second support plates 112. The four edges of the placement plate 115 extend upward to form a protective frame 116. When the placement plate 115 is needed, the user can move the position of the second support plate 112 in the long sliding hole 114 so that the first support plate 111, the second support plate 112 and the third support plate 113 form a stable triangular support frame, which can provide stable support for the placement plate 115. After use, the user can move the position of the second support plate 112 in the long sliding hole 114 again so that the first support plate 111, the second support plate 112 and the third support plate 113 are folded together, thereby retracting the workbench 11 to one side of the toolbox 1.

[0052] like Figure 4 and Figure 5 As shown, the front end of the drawer box 2 in this embodiment has an installation cavity 21. Slide rails 22 are installed on both inner walls of the installation cavity 21, and sliders 23 are installed on both outer walls of the drawer 3. The sliders 23 are slidably connected to the slide rails 22. A shielding strip 5 is installed at the front end of the drawer box 2, and a locking unit 6 is installed at the rear end of the drawer box 2. When the drawer 3 is closed, the locking unit 6 connects to the drawer 3, thereby fixing the drawer 3. At this time, the front end of the drawer 3 will also abut against the shielding strip 5, thereby sealing the gap between the drawer box 2 and the drawer 3. An ultra-high frequency radio frequency antenna 4 is installed inside the top of the drawer box 2. The number of ultra-high frequency radio frequency antennas 4 can be determined according to the size of the drawer 3 and the number of tools. In this embodiment, two ultra-high frequency radio frequency antennas 4 are preferably used, with the two antennas spaced apart on the left and right sides, so that the recognition range can cover the entire drawer 3.

[0053] like Figure 6 As shown, the locking unit 6 specifically includes an electric lock 61 and a locking ring 62. The electric lock 61 is installed at the rear end of the drawer box 2, and the locking ring 62 is installed at the rear end of the drawer 3. A through hole is provided at the rear end of the drawer box 2 corresponding to the position of the locking ring 62. When the drawer 3 is closed, the locking ring 62 will pass through the through hole and insert into the electric lock 61, thereby fixing the drawer 3.

[0054] Preferably, the front end of the electric lock 61 is equipped with a pin 63. The pin 63 passes through the drawer box 2 and is located in the mounting cavity 21. When the drawer 3 is closed, it will abut against the pin 63 and compress it. When the drawer 3 needs to be opened, the electric lock 61 releases the locking ring 62, and at the same time the pin 63 releases pressure to push the drawer 3 to open outward, thereby achieving the effect of automatic opening of the drawer 3.

[0055] When the tools placed in drawer 3 are heavy, it is difficult to push drawer 3 open by relying solely on pin 63. Therefore, a spring pin 64 can be added below the electric lock 61 in this embodiment. The spring pin 64 passes through the drawer box 2 and is located in the mounting cavity 21. When drawer 3 is closed, it will simultaneously abut against pin 63 and spring pin 64 and compress them. When drawer 3 needs to be opened, electric lock 61 releases lock ring 62, and pin 63 and spring pin 64 push drawer 3 open together. This is suitable for scenarios where drawer 3 is heavy.

[0056] like Figure 7 As shown, since the power bank 9 is installed inside the toolbox 1, and the toolbox 1 needs to be moved frequently during use, some vibration is easily generated during the movement. Therefore, the power bank 9 in this embodiment is also equipped with a positioning component 8. The positioning component 8 specifically includes a positioning seat 81 installed on the inner wall of the bottom of the toolbox 1. The positioning seat 81 extends upward around its perimeter to form a positioning frame 82. The lower part of the power bank 9 is inserted into the positioning frame 82, and the upper part of the power bank 9 is fitted with a positioning hoop 83. The positioning hoop 83 is connected to the toolbox 1 by fasteners. The positioning frame 82 and the positioning hoop 83 can play a role in fixing and shock absorption.

[0057] like Figure 8As shown, the control system 7 specifically includes a control box 71 installed on the top of the toolbox 1. The front of the control box 71 is equipped with a control screen 72 and a card reader 73. When using the tool, the user needs to swipe their card at the card reader 73 to obtain their identity information. After successful identity verification, the user can select the desired tool from the control screen 72. The control screen 72 will then control the corresponding drawer 3 to open. After the user takes the tool and closes the drawer 3, the ultra-high frequency radio frequency antenna 4 will re-check the tools in the drawer 3 to confirm that the user has correctly taken the correct tool. The control box 71 is also equipped with an alarm 75. When the user takes the wrong tool or other abnormal situation, the alarm 75 will sound an alarm to remind the user. Simultaneously, a radio frequency antenna 74 is also installed on one side of the control box 71. This antenna 74 is mainly used to identify the returned tool information. After using the tool, the user can bring the corresponding tool close to the radio frequency antenna 74. After the antenna 74 identifies the tool information, it will open the corresponding drawer 3, and the user can then place the tool back into the corresponding drawer 3.

[0058] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
