In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0048] In this application, the term "and / or" describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0049] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0050] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. associated with a specific value. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0051] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts.

[0052] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.

[0053] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] FIG1 shows a toolbox system 100 that can be used to store items, such as accessories, tools, charging devices, power devices, lighting devices, cooling devices, heating devices, air blowers 127, storage boxes, etc. It should be noted that storing items in this application is not limited to storing items within a storage box, but also includes securing items outside of a storage box and keeping them relatively fixed to the storage box, which is also referred to as storing items in a storage box.

[0055] In order to clearly illustrate the technical solution of this application, the top, bottom, front, back, left, and right are defined as shown in Figure 1. It should be noted that, unless otherwise specified, the top, bottom, front, back, left, and right mentioned below all refer to the state of the toolbox system 100 when it is stationary as shown in Figure 1.

[0056] As shown in FIG. 1 to FIG. 7 , the tool box system 100 includes a first type of storage box 10 .

[0057] The first type storage box 10 includes a box body 13, a travel assembly 14, a handle assembly 18, and an interlocking assembly 12. The box body 13 is the main component of the first type storage box 10. The box body 13 has a storage cavity 11, which can store items. The travel assembly 14 is connected to the box body 13. The travel assembly 14 includes one or more wheels 141, and the travel assembly 14 can move the box body 13 relative to the ground. The handle assembly 18 is connected to the box body 13. The handle device has a first handle 181 for the user to hold. The first handle 181 can move relative to the box body 13, that is, it can be understood that the first handle 181 can be extended and retracted relative to the first handle 181. As another embodiment, the first handle 181 can rotate relative to the box body 13. The user can push and pull the first handle 181 to rotate the wheel 141 relative to the ground, thereby allowing the box body 13 to move relative to the ground. The interlocking assembly 12 is used to connect the storage box to the first type storage box 10 so that the storage boxes can remain relatively fixed.

[0058] In the up-down direction, the box body 13 includes an upper top wall 131 and a lower bottom wall 132 relatively arranged. In the left-right direction, the box body 13 includes a left side wall 133 and a right side wall 134 relatively arranged. In the front-to-back direction, the box body 13 includes a front side wall 135 and a rear side wall 136 relatively arranged. The upper top wall 131, the lower bottom wall 132, the left side wall 133, the right side wall 134, the front side wall 135 and the rear side wall 136 surround to form a accommodating cavity 11 for accommodating items, wherein the left side wall 133 and the front side wall 135, as well as the right side wall 134 and the front side wall 135 are connected by a connecting section 138. An opening 15 is formed on the box body 13, which can be opened to display the storage cavity 11. The opening 15 is set at the lower end of the upper top wall 131. The specific first-class storage box 10 also includes a first connecting member 16 that cooperates with the opening 15. The first-class storage box 10 includes at least one first connecting member 16. The first connecting member 16 can move relative to the box body 13. During the movement of the first connecting member 16 relative to the box body 13, the opening 15 has an open state and a closed state. When the opening 15 is in the open state, the storage cavity 11 is fully unfolded. At this time, the user can take out the items in the storage cavity 11, and of course, can also place items in the storage cavity 11. When the opening 15 is in the closed state, the storage cavity 11 is basically completely closed, and the user cannot take or store items. As another embodiment, the storage box can also be without the upper top wall 131, that is, the storage box is directly open, and the user can directly take or store various items from the storage cavity 11. In the present application, the first connecting member 16 can be completely consistent in structure or completely inconsistent in structure.

[0059] In one embodiment, the first connector 16 is capable of translating relative to the housing 13. The first type storage box 10 includes a connecting assembly 19, which is used to secure the first connector 16 to the housing 13, preventing the first connector 16 from sliding out of the housing 13 without external force. This prevents the first connector 16 from sliding out of the housing 13 during certain movements, potentially causing items within the housing 13 to fall. The first connector 16 has a locked state and an unlocked state. When the first connector 16 is in the locked state, the first connector 16 and the housing 13 remain fixed relative to each other without external force. When the first connector 16 is in the unlocked state, the first connector 16 can slide forward and backward without separating from the housing 13. It can also be understood that when a user needs to access items within the first type storage box 10, they simply pull out the first connector 16, exposing the storage cavity 11, and can then remove or store items within the storage cavity 11. When the user does not need to use the first type storage box 10 , the user only needs to push the first connecting member 16 into the accommodating cavity 11 .

[0060] The first type storage box 10 includes a track assembly 161, which guides the first connector 16 to slide within the box body 13. Two sets of track assemblies 161 are provided, one on each side of the first connector 16. The track assemblies 161 on both sides have substantially identical structures. The track assembly 161 includes a first guide 164 and a second guide 165. The first guide 164 is fixedly connected to the box body 13, while the second guide 165 is fixed to one side of the box body 13. The second guide 165 partially snaps into the first guide 164 and is configured to slide relative to the first guide 164. The box body 13 can be connected to multiple first connectors 16 of different sizes. In other words, multiple first guides 164 can be provided within the storage cavity 11. This allows the second guides 165 on first connectors 16 of different heights to mate with the first guide 164. It is understood that the user can select a first connector 16 that matches the size of the opening 15, or the user can select two. This arrangement allows users to select first connectors 16 of different sizes according to their needs. Of course, as other embodiments, the first type storage box 10 may be provided with multiple openings 15, each of which is provided with a first connector 16 that matches the first opening 15.

[0061] The first connector 16 can be in the shape of an open box, forming a storage space 166. A user can place items in the storage space 166 and then push the first connector 16 into the accommodating cavity 11 to store the items in the accommodating cavity 11. The tool box system 100 also includes a partition plate 167 that can be detachably mounted on the first connector 16 to divide the first connector 16 into a plurality of small storage spaces 166, which facilitates classified storage.

[0062] The connecting assembly 19 includes a first stopper 191, a second stopper 192, a biasing member 193, and a locking member 194. The locking member 194 is fixedly connected to or integrally formed with the housing 13. The locking member 194 and the second stopper 192 cooperate to maintain relative fixation between the first connecting member 16 and the housing 13. The biasing member 193 is disposed between the second stopper 192 and the first stopper 191 and constantly applies a downward bias to the second stopper 192. The first stopper 191 is fixedly connected to or integrally formed with the first connecting member 16. A locking portion 195 is formed on the locking member 194, and a snap-fitting portion 196 is provided on the second stopper 192. When the locking portion 195 engages with the snap-fitting portion 196, the first connecting member 16 is locked. When the locking portion 195 and the snap-fitting portion 196 are separated, the first connecting member 16 is unlocked. In this embodiment, the first stop member 191 is integrally formed with the first connecting member 16, that is, the first connecting member 16 forms an accommodating cavity 11, the biasing member 193 is arranged in the accommodating cavity 11, and the second stop member 192 is at least partially arranged in the accommodating cavity 11, and the second stop member 192 can move synchronously with the first stop member 191, one end of the biasing member 193 abuts on the first connecting member 16, and the other end abuts on the second stop member 192. The biasing member 193 is given a pre-tightening force when it is installed, so that it always applies a downward biasing force to the second stop member 192. This biasing force ensures that when the first connecting member 16 is in a locked state, the locking portion 195 and the clamping portion 196 always maintain a coordinated state.

[0063] The locking portion 195 is positioned along the path of movement of the engaging portion 196. The locking portion 195 is a groove or a hole, and the engaging portion 196 is a downwardly facing protrusion on the second stopper 192. The biasing force applied by the biasing member 193 to the second stopper 192 ensures that the protrusion remains engaged within the hole in the absence of external forces. When the first connector 16 is locked, the protrusion is engaged within the hole. To unlock, the user simply applies an upward force to the second stopper 192 to overcome the biasing force, disengaging the protrusion from the hole and allowing the first connector 16 to slide outward from the housing 13. To lock the first connector 16, the user simply pushes the first connector 16 into the housing 13. The biasing force applied by the biasing member 193 to the second stopper 192 is maintained until the protrusion engages within the hole, thereby maintaining relative stability between the first connector 16 and the housing 13. In this embodiment, two biasing members 193 may be provided.

[0064] The first-category storage box 10 further includes a locking plate 162 and a connector 163. The locking plate 162 is used to prevent the first connectors 16 from sliding out of the box body 13. The connector 163 is used to connect the box body 13 and the locking plate 162. The locking plate 162 is disposed on the front side of the first-category storage box 10 and passes through all of the first connectors 16 of the first-category storage box 10. Specifically, two hollow protrusions are formed on the upper top wall 131 of the first-category storage box 10, namely a first protrusion 151 and a second protrusion 152. The first protrusion 151 and the second protrusion 152 are spaced apart, and the locking plate 162 can be inserted into the first protrusion 151 and the second protrusion 152. In the up and down directions, the first protrusion 151 and the second protrusion 152 are arranged on both sides of all the first connecting parts 16 of the first type storage box 10, and the locking plate 162 is in the shape of a long strip. In this way, after the locking plate 162 is inserted into the first protrusion 151 and the second protrusion 152, the locking plate 162 can better prevent the first connecting part 16 from slipping out of the box body 13, thereby ensuring the stability of the connection between the first connecting part 16 and the box body 13.

[0065] The locking plate 162 includes a strip portion 168 and a bent portion 169. The strip portion 168 and the bent portion 169 are fixedly connected or integrally formed. The strip portion 168 and the bent portion 169 are arranged at an angle. Specifically, the strip portion 168 and the bent portion 169 are arranged at a right angle. The locking plate 162 is inserted downwardly into the first protrusion 151 and the second protrusion 152 until the bent portion 169 contacts the first protrusion 151, at which point the locking plate 162 stops moving downward. The first protrusion 151 and the bent portion 169 are also formed with corresponding locking holes 153. The user can use the connector 163 to lock the locking plate 162 to the box body 13, further ensuring the stability of the connection between the first connector 16 and the box body 13 and also preventing theft. In this embodiment, the connector 163 can be a padlock.

[0066] As another embodiment, the first connecting member 16 can rotate relative to the box body 13. The first connecting member 16 is pivotally connected to the box body 13, that is, the first connecting member 16 can be flipped to a vertical position relative to the box body 13. In this case, the user pushes the first connecting member 16 to store the first connecting member 16 in the accommodating cavity 11 of the box body 13. At this time, the opening 15 of the box body 13 is in an open state, and the user can place or remove items in the accommodating cavity 11 as needed. When the user needs to close the opening 15, they only need to pull the first connecting member 16 out of the accommodating cavity 11 and flip it until the first connecting member 16 is locked with the box body 13, and the opening 15 is now closed.

[0067] As another embodiment, a plurality of openings 15 are formed on the box body 13 , that is, the first type storage box 10 includes a plurality of connectors that cooperate with the openings 15 , so that the user can place items in different openings 15 according to needs.

[0068] The tool box system 100 further includes an interlocking assembly 12, which is disposed on the upper side of the first type storage box 10. The tool box system 100 further includes a plurality of storage boxes, which for ease of description are defined herein as second type storage boxes 20, which can be connected to the upper side of the first type storage box 10 via the interlocking assembly 12. Specifically, the interlocking component 12 includes two symmetrically arranged installation components 121. The structures of the two installation components 121 are basically the same. The installation components 121 are arranged on both sides of the upper top wall 131. The installation components 121 include a resilient fastener 122 and a positioning component 123. The fastener 122 is connected to the upper top wall 131 of the first type storage box 10, and the positioning component 123 is connected to the lower bottom wall 132 of the second type storage box 20. When the user needs to connect the second type storage box 20 to the first type storage box 10, the second type storage box 20 is placed downward to lock the fastener 122 and the positioning component 123, thereby connecting the first type storage box 10 and the second type storage box 20. When the user needs to remove the second type storage box 20 from the first type storage box 10, just push the fastener 122 outward to separate the fastener 122 from the positioning component 123, and then the second type storage box 20 can be removed from the first type storage box 10. In this configuration, the third-category storage box 30 can be connected to the upper wall 131 of the first-category storage box 10 via the mounting assembly 121, and the fourth-category storage box can also be connected to the upper wall 131 of the third-category storage box 30 via the mounting assembly 121. Of course, the user can connect more storage boxes to the fourth-category storage box. It should be noted that, unless otherwise specified, in this application, the first-category storage box 10, the second-category storage box 20, the third-category storage box 30, and the fourth-category storage box are merely used to distinguish different types of storage boxes, and do not limit whether the storage boxes have different structures. In other words, the first-category storage box 10, the second-category storage box 20, the third-category storage box 30, and the fourth-category storage box can be the same storage box, can have partially identical structures, or can have completely different structures. In this embodiment, only a feasible interlocking component 12 is introduced. The interlocking component 12 can also be an interference structure, that is, the lower bottom wall 132 of the second-type storage box 20 has a protruding structure, and the upper top wall 131 of the first-type storage is formed with a groove for inserting the protruding structure. The specific structure of the interlocking component 12 is not limited here, as long as the second-type storage box 20 can be connected to the first-type storage box 10, further, the structure can also enable the third-type storage box 30 to be connected to the upper side of the second-type storage box 20.

[0069] As another embodiment, the structures of the two mounting components of the interlocking component 12 can also be inconsistent. One mounting component 121 includes a resilient buckle 122 and a positioning component 123, and the other mounting component 124 includes a rotatable stopper 125 and a resisting component 126. The stopper 125 is connected to the first type storage box 10. On the upper top wall 131, the supporting member 126 is connected to the item that needs to be installed on the first type storage box 10, which may be a storage box, a blowing device, a refrigeration device, a tool, an accessory, etc. This embodiment takes the blowing device 127 as an example to describe it clearly, and the supporting member 126 is connected to the blowing device 127. When the user needs to connect the blowing device 127 to the first type storage box 10, first flip the stopper 125 out from the upper top wall 131, and then the supporting member 126 on the blowing device 127 is pressed against the stopper 125, and the other side of the blowing device 127 is placed downward so that the positioning member 123 of the blowing device 127 is locked with the snap member 122 on the first type storage box 10, thereby locking the blowing device 127 to the first type storage box 10. When the user needs to remove the blowing device 127, he only needs to push the latch 122 outward to separate the latch 122 from the positioning member 123, and then the blowing device 127 can be removed. After removal, the user flips the stopper 125 so that it is accommodated on the upper top wall 131. To increase user selection, both mounting components can be set on the upper top wall 131 (as shown in Figure 1), so that the user can select the mounting component according to needs to connect other items to the first type storage box 10.

[0070] The toolbox system 100 also includes an external attachment assembly 17, which is used to attach items to the top of the storage box. The external attachment assembly 17 can be attached to the sidewall of the storage box or to the connecting section 138 of the storage box. The external attachment assembly 17 includes an intermediate component 171 and an external attachment 172. One or more intermediate components 171 and external attachment 172 can be provided. One or more intermediate components 171 can be mounted on the connecting section 138 in the vertical direction. The intermediate components 171 are connected to the connecting section 138 using one or a combination of screws, latches, rivets, suction, interference fit, and snap fasteners. In this embodiment, the intermediate component 171 is screwed to the connecting section 138, i.e., the intermediate component 171 is fixed to the connecting section 138 by screws. One or more external attachments 172 can be mounted on the intermediate component 171. These external attachments 172 can be connected to the intermediate component 171 using one or a combination of screws, latches, rivets, suction, interference fit, and snap fasteners. The external attachment 172 can be one or a combination of a battery pack attachment, a cable attachment, a ruler attachment, a support, a tool accessory box attachment, and a power tool attachment. Alternatively, the external attachment 172 can be connected to the side wall of the storage box using one or a combination of screws, latches, rivets, suction, interference fit, and snap fasteners. This allows users to attach more items to the storage box. A metal guard bar is embedded in the connecting section 138.

[0071] In the up and down directions, the walking assembly 14 is at least partially arranged on the lower side of the box body 13, and the user can push and pull the box body 13 through the walking assembly 14. The walking assembly 14 includes at least one wheel 141. Figures 1 to 7 show the structural schematic diagram of the toolbox system 100 in the first embodiment. In this embodiment, the walking assembly 14 includes two wheels 141, and the two wheels 141 are both arranged on the left side of the box body 13. The first handle 181 and the wheel 141 are arranged on the same side of the box body 13. As a specific embodiment, the handle assembly 18 includes a guide frame 182 and a first handle 181, and the first handle 181 can move within the guide frame 182. During the movement of the first handle 181 within the guide frame 182, there will be at least three states. When the first handle 181 is in the first state, the first handle 181 is in a retracted state, that is, at this time, most of the first handle 181 is accommodated in the guide frame 182. When the first handle 181 is in the second state, the first handle 181 is in an extended state. At this time, most of the first handle 181 is extended outside the guide frame 182, and the user can hold the first handle 181 to drive the walking assembly 14. When the first handle 181 is in the third state, the first handle 181 is completely separated from the guide frame 182. In other words, the guide frame 182 and the first handle 181 are now two parts.

[0072] Wheels 141 are connected to the rear sidewall of the box body 13. The first type storage box 10 has a longitudinal distance. When this distance is less than or equal to 700 mm, the opening 15 is located on the front sidewall 135. In this embodiment, the longitudinal direction is parallel to the left-right direction. This arrangement allows the user to open the first connector 16 directly on the front sidewall 135, allowing for easy storage and retrieval of items within the storage cavity 11, making operation more convenient.

[0073] In a specific embodiment, the first type storage box 10 includes two first connectors 16, which are arranged substantially vertically. This arrangement facilitates user classification and management of items. Furthermore, the first connectors 16 are movable relative to the box body, without interfering with the wheels 141 during movement.

[0074] When the first-type storage box 10 is actually in use, the user can connect the second-type storage box 20 to the first-type storage box 10 via the interlocking assembly 12. The user can then adjust the first handle 181 to the second position and then, by gripping the first handle 181, drive the wheels 141 to rotate, thereby moving the first-type storage box 10 and the second-type storage box 20 connected to the first-type storage box 10. In this embodiment, the first-type storage box 10 is generally cubical, with the walking assembly 14 connected to the lower end of the first-type storage box 10. The lower end of the box body 13 is provided with abutments 137 that cooperate with the wheels 141, thereby allowing the first-type storage box 10 to remain upright. When the first-class storage box 10 is stationary as shown in Figure 1, there will inevitably be at least three contact points between the box body 13 of the first-class storage box 10 and the wheel 141. The plane where the contact points are located is defined as the support plane P, wherein the distance L from the support plane P to the guide frame 182 in the direction perpendicular to the support plane P is greater than 0 mm and less than or equal to 550 mm. Under common working conditions, users will use a pickup truck to transport the tool box system 100. Among all storage boxes, the first-class storage box 10 needs to consider the structure of the handle assembly 18 in the up and down directions relative to storage boxes of other structures. Therefore, the design of the height dimension of the first-class storage box 10 is particularly important. The first handle 181 is set to be separated from the guide frame 182, so that the dimension of the box body 13 in the length direction can be as large as possible, thereby ensuring that the storage cavity 11 of the first-class storage box 10 can accommodate more items, and at the same time making the storage box structure design more reasonable. Furthermore, the distance from the support plane P to the guide frame 182 is set within the above range. When the user needs to move the first type storage box 10, the first handle 181 can be pulled out from the guide frame 182, and then the first type storage box 10 can be placed in the pickup truck.

[0075] In this embodiment, along the front-to-back direction, the opening 15 is arranged at the front side, and the handle assembly 18 and the walking assembly 14 are arranged at the rear side. This arrangement can facilitate the user to push and pull the first connecting member 16.

[0076] Figures 8 to 15 show schematic structural diagrams of the toolbox system 200 in the second embodiment. In this embodiment, the structures and principles of the interlocking assembly 220, the guide rail assembly 230, the external assembly 240, etc. are basically the same as those in the first embodiment. The difference lies in the specific structures of the box body 211, the handle assembly 260, the walking assembly 250, etc. of the first type storage box 210. That is to say, the parts of the first embodiment that are compatible with the present embodiment can be applied to the present embodiment. The following only introduces the differences between the present embodiment and the first embodiment.

[0077] As shown in Figures 8 to 10, the walking assembly 250 includes two wheels 251, both of which are disposed on the left side of the box 211. The wheels 251 rotate about a first rotation axis, and the direction in which the opening of the first type storage box 210 is unfolded is substantially parallel to the direction of the first rotation axis. The first type storage box 210 also includes a handle assembly 260, which includes a first handle 261. The first handle 261 is slidably connected to the box 211. The first handle 261 has a first state and a second state relative to the box 211. When the first handle 261 is in the first state, the first handle 261 is in a retracted state, where most of the first handle 261 is contained within the box 211. When the first handle 261 is in the second state, the first handle 261 is in an unfolded state, where most of the first handle 261 is extended outside the box 211 and the first handle 261 is connected to the box 211. When the first type storage box 210 is actually used, the user can connect the second type storage box 270 to the first type storage box 210, so that the user can adjust the first handle 261 to the second state, and then hold the first handle 261 to drive the rotation of the wheel 251, thereby driving the first type storage box 210 and the second type storage box 270 connected to the first type storage box 210 to move together.

[0078] The wheel 251 is set on the rear side wall of the box body. The first type storage box 210 has a distance L3 in the reverse direction of the length. When the distance L3 is greater than 700 mm, the opening is set on the front side wall. This setting makes it convenient for the user to still open the first type storage box 210 when the first type storage box 210 is connected to the second type storage box 270.

[0079] The first type storage box 210 has two first connectors 280, which are arranged side by side in the left-right direction without interference. The first connectors 280 are recessed so as not to interfere with the wheels 251 along their moving paths.

[0080] In this embodiment, at least two interlocking assemblies 220 are provided on the top wall 214 of the first-type storage box 210. This arrangement allows a user to mount at least two other storage boxes on the first-type storage box 210. Specifically, a second-type storage box 270 and a third-type storage box 271 can be mounted side by side on the top wall 214 of the first-type storage box 210 via the interlocking assemblies 220. By gripping the first handle 261 and driving the wheels 251, the user can move the first-type storage box 210 and the second-type storage box 270 connected to the first-type storage box 210 together. Alternatively, the user can attach additional storage boxes to the second-type storage box 270 and the third-type storage box 271, allowing the user to move more storage boxes when moving the first-type storage box 210. Furthermore, the user can also attach other items to the first-type storage box 210 via the interlocking assemblies 220, such as heating devices, cooling devices, hair dryers, tools, and the like.

[0081] As shown in Figure 13, the distance L1 from the upper top wall 214 to the lower bottom wall 215 of the first type storage box 210 in the vertical direction is less than or equal to 450 mm, and the distance L3 from the left side wall 216 to the right side wall 217 of the first type storage box 210 in the left and right direction is greater than 450 mm. It can also be understood that the length dimension of the first type storage box 210 is greater than the height dimension of the first type storage box 210. The tool box system 200 is carried from the tool storage site to the workplace. The distance between the tool storage site and the workplace is often relatively far. The user needs to use a vehicle to transport the tool box system 200 to the workplace. Due to the height limit of some vehicles, the first type storage box 210 can be placed directly in the vehicle. By setting the height dimension of the first type storage box 210 within the above range, the first type storage box 210 can be directly carried into the vehicle, which is convenient for users to transport.

[0082] The first type storage box 210 further includes abutting portions 218, which can cooperate with the wheels 251. When the first type storage box 210 is positioned as shown in FIG13 , at least a portion of the abutting portions 218 and at least a portion of the wheels 251 can simultaneously contact the ground. The wheels 251 and the abutting portions 218 have at least three contact points when in contact with the ground, and the plane where these contact points lie is defined as the support plane P. When the wheels 251 and the abutting portions 218 are in contact with the ground, the center of gravity G of the first type storage box 210 and the first connection L2 with the ground are substantially perpendicular to the support plane P. The length of the first-type storage box 210 is greater than its height. This means that when the first-type storage box 210 is placed in the tool storage area as shown in FIG11 , it will inevitably occupy a large space. Therefore, by providing the abutting portion 218 and cooperating with the wheels 251, the first-type storage box 210 can remain upright when placed as shown in FIG13 . This allows the user to place the first-type storage box 210 in the tool storage area, effectively and rationally utilizing the storage space there. It should be noted that the center of gravity G of the first-type storage box 210 refers to the center of gravity G when no other items are attached to the first-type storage box 210.

[0083] A positioning slot 219 is also provided on the upper top wall 214 of the first type storage box 210. In actual use, the upper top wall 214 of the first type storage box 210 can be used as a workbench. Specifically, a plurality of positioning holes 212 are provided on the positioning slot 219. The user uses screws to pass through the table saw and the support member 213 to lock the table saw on the upper top wall 214. In this way, the user can use the table saw directly on the upper top wall 214. The support member 213 can be snapped into the positioning slot 219 to support the table saw. Of course, other table-type tools can also be used. The user can also snap the workpiece to be cut into the positioning slot 219, and then use other cutting tools to cut the workpiece 272 to be cut.

[0084] Figure 16 shows a schematic structural diagram of the toolbox system 300 in the third embodiment. In this embodiment, the principle thereof may be basically the same as that of the first embodiment or the second embodiment, the difference being that the structures of the handle assembly 310 and the walking assembly 320 are different. That is to say, the parts of the first embodiment or the second embodiment that are compatible with the present embodiment may all be applied to the present embodiment. The following only introduces the differences between the present embodiment and the first embodiment.

[0085] As shown in Figure 16 , as one embodiment, the walking assembly 320 has four wheels, which are respectively arranged around the bottom wall 331 of the box 330. The handle assembly 310 is connected to the box 330 and includes a first handle 311. The first handle 311 is connected to the box 330. The first handle 311 and the box 330 can be connected by a rotational connection or a sliding connection. The first handle 311 and the box 330 can be connected by an infinite rotation connection.

[0086] As a feasible embodiment, as shown in FIG17 , the tool box system 100 further includes a drive device 40 connected to the first type storage box 10 . The drive device 40 can drive the travel assembly 14 to move or stop. When the drive device 40 drives the travel assembly 14 to move, the user does not need to exert much force when pushing or pulling the first type storage box 10; they only need to control the forward direction of the first type storage box 10. The drive device 40 can be a motor with a power supply. Alternatively, the drive device 40 can be a hub motor.

[0087] The above shows and describes the basic principles, main features and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the scope of protection of this application.
