Description

Technical Field

[0001] This application relates to the field of storage accessories technology, and in particular to a storage box for engineering machinery and engineering machinery. Background Technology

[0002] Storage boxes are essential functional components for storing items. For example, in-vehicle storage boxes are crucial for storing items inside a vehicle, typically located near the center console, dashboard, or seats. As automotive design continues to evolve, the function and structure of storage boxes are also constantly developing, such as the storage boxes in refrigerators.

[0003] In related technologies, hinged storage boxes are used. The hinged storage box connects the cover and the box body through a split hinge structure to realize the opening and closing function, such as realizing the flipping of the cover through a movable pivot and linkage mechanism.

[0004] However, the aforementioned split hinge and linkage mechanism results in a large number of parts, making assembly difficult and costly. Furthermore, the cover plate occupies extra space after being unfolded and cannot fit the body contour. Utility Model Content

[0005] This application provides a storage box for engineering machinery and engineering machinery, which solves the problems of existing hinged storage boxes having a large number of parts, difficult assembly, high cost, and occupying extra space after the cover is unfolded, making it impossible to fit the contour of the vehicle body due to the separate hinge and linkage mechanism.

[0006] To achieve the above objectives, the technical solution of this application is as follows:

[0007] This application provides a storage box for engineering machinery, comprising: a cover assembly, wherein at least one side of the cover assembly is provided with a first sliding member; a box body, wherein at least one side of the box body is provided with a second sliding member, the box body has a receiving cavity, the cover assembly is rotatably disposed on the box body to close the receiving cavity, the first sliding member and the second sliding member are slidably connected; an air duct, one end of the air duct communicating with the receiving cavity, and the other end of the air duct being used to connect with the engineering machinery; the cover assembly is configured such that, under the action of an external force, the cover assembly slides and rotates relative to the box body to open or close the receiving cavity.

[0008] In one possible implementation, the engineering machinery storage box in this application embodiment has an arched guide rail as the first sliding member and a sliding groove adapted to the arched guide rail as the second sliding member. The arched guide rail and the sliding groove are slidably connected, and the bottom of the first sliding member has a buffer.

[0009] In one possible implementation, the engineering machinery storage box in this application embodiment has a rotating arm on at least one side of the cover assembly. The rotating arm is rotatably connected to the box body. When the cover assembly slides relative to the box body to open the receiving cavity, the rotating arm rotates relative to the box body so that the cover assembly is suspended in the open position.

[0010] In one possible implementation, the suspension angle of the cover assembly of the engineering machinery storage box in this embodiment of the application is greater than or equal to 45° and less than or equal to 65°.

[0011] In one possible implementation, the engineering machinery storage box in this application embodiment further includes a connector, a rotating arm having a connection hole, the connector passing through the connection hole and connecting to the rotating arm, and the rotating arm rotating relative to the box body around the connector.

[0012] In one possible implementation, the engineering machinery storage box in this application embodiment further includes an elastic element, one end of which is connected to the rotating arm, and the other end of which is connected to the box body.

[0013] In one possible implementation, the engineering machinery storage box in this application embodiment has a baffle and a seal inside the box body. The baffle is connected to the air inlet, and the air inlet is connected to the receiving cavity. The baffle is used to guide the airflow entering from the air inlet to the receiving cavity, and the seal is provided at the air inlet.

[0014] In one possible implementation, the engineering machinery storage box in this application embodiment further includes a locking member. The locking member is disposed on the side of the cover assembly facing the box body. The box body has a slot. When the receiving cavity is closed, the locking member is inserted into the slot. When the receiving cavity is opened, the locking member is disengaged from the slot.

[0015] In one possible implementation, the engineering machinery storage box in this application embodiment has a cover assembly with a bent upper cover and a lower cover, the extension direction of the upper cover intersecting the extension direction of the lower cover, and at least one of the upper cover and the lower cover having a handle portion. When the receiving cavity is closed, the upper cover is located at the top of the receiving cavity and the lower cover is located at the side of the receiving cavity. When the receiving cavity is opened, the upper cover is located at the side of the receiving cavity.

[0016] In addition, this application also provides a vehicle, including a vehicle body and an engineering machinery storage box of any of the above embodiments disposed on the vehicle body, wherein the air conditioning system of the vehicle body is connected to the air duct of the storage box.

[0017] This application provides a storage box and vehicle for engineering machinery. The storage box includes a cover assembly with a first sliding member on at least one side; a box body with a second sliding member on at least one side; the box body having a receiving cavity; the cover assembly rotatably covering the box body to close the receiving cavity; the first sliding member and the second sliding member are slidably connected; the cover assembly is configured such that, under the action of an external force, the cover assembly slides and rotates relative to the box body to open or close the receiving cavity. This application utilizes the sliding connection between the first and second sliding members to allow the cover assembly to slide relative to the box body. Combined with the rotation of the cover assembly, it enables the cover assembly to simultaneously slide and rotate relative to the box body under external force, achieving smooth opening and closing of the storage cavity and improving operational convenience. Compared to traditional hinged structures, the combined sliding and rotating motion trajectory allows the cover assembly to open without occupying extra space (e.g., hovering on the side or below the box body), better conforming to the contours of the vehicle body or installation environment and adapting to compact space layout requirements. Furthermore, this application eliminates the need for complex linkages or hinge mechanisms, achieving this through the first sliding member and the cover assembly. This application achieves opening and closing functions through the cooperation of sliding and rotation, reducing the number of parts, lowering assembly difficulty and production costs. Simultaneously, it connects to the air conditioning system of the construction machinery via an air duct, and the storage cavity is connected to the air duct, enabling linkage between the storage box and the construction machinery's air conditioning system, utilizing the air conditioning airflow to achieve cooling or heating functions for the storage box.

[0032] Storage boxes are essential functional components for storing items. For example, in-vehicle storage boxes are crucial for storing items inside a vehicle, typically located near the center console, dashboard, or seats. As automotive design continues to evolve, the function and structure of storage boxes are also constantly developing, such as the storage boxes in refrigerators.

[0033] In related technologies, hinged storage boxes are used. The hinged storage box connects the cover and the box body through a split hinge structure to realize the opening and closing function, such as realizing the flipping of the cover through a movable pivot and linkage mechanism.

[0034] However, the aforementioned split hinge and linkage mechanism results in a large number of parts, making assembly difficult and costly. Furthermore, the cover plate occupies extra space after being unfolded and cannot fit the body contour.

[0035] In view of the above, this application provides a storage box for engineering machinery and a vehicle. The storage box includes a cover assembly, with a first sliding member on at least one side of the cover assembly; a box body, with a second sliding member on at least one side of the box body, and the box body has a receiving cavity. The cover assembly is rotatably mounted on the box body to close the receiving cavity. The first sliding member and the second sliding member are slidably connected; an air duct, one end of which communicates with the receiving cavity, and the other end of which is used to connect with the engineering machinery; the cover assembly is configured such that, under the action of an external force, the cover assembly slides and rotates relative to the box body to open or close the receiving cavity. This application utilizes the sliding connection between the first and second sliding members to allow the cover assembly to slide relative to the box body. Combined with the rotation of the cover assembly, the cover assembly can simultaneously slide and rotate relative to the box body under external force, achieving smooth opening and closing of the storage cavity and improving operational convenience. Compared to traditional hinged structures, the combined sliding and rotating motion trajectory allows the cover assembly to open without occupying extra space (such as hovering on the side or below the box body), better conforming to the contours of the vehicle body or installation environment and adapting to the needs of compact space layouts. Furthermore, this application eliminates the need for complex linkage or hinge mechanisms. Through the structure of the first sliding member and the cover assembly itself, the opening and closing function is achieved through the cooperation of sliding and rotation, reducing the number of parts, lowering assembly difficulty and production costs. Simultaneously, it connects to the air conditioning system of the construction machinery via an air duct, and the storage cavity is connected to the air duct, enabling linkage between the storage box and the air conditioning system of the construction machinery, and utilizing the air conditioning airflow to achieve the cooling or heating function of the storage box.

[0036] This application provides a storage box for engineering machinery, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 The device includes: a cover assembly 100, with a first sliding member 110 on at least one side; a box body 200, with a second sliding member 210 on at least one side, and a receiving cavity 202. The cover assembly 100 is rotatably mounted on the box body 200 to close the receiving cavity 202, and the first sliding member 110 and the second sliding member 210 are slidably connected; an air duct 300, one end of which communicates with the receiving cavity 202, and the other end of which is used to connect with engineering machinery. The cover assembly 100 is configured such that, under the action of an external force, the cover assembly 100 slides and rotates relative to the box body 200 to open or close the receiving cavity 202.

[0037] The cover assembly 100 has a first sliding member 110 on at least one side, for example, the cover assembly 100 has a first sliding member 110 (such as a guide rail) on both sides. The cover assembly 100 can be a bent plate for fitting snugly to the outer contour of the box body 200.

[0038] Box body 200, such as Figure 6As shown, at least one side of the box body 200 has a second sliding member 210 (such as a sliding groove). For example, the inner sidewalls of the left and right sides of the box body 200 have sliding grooves that are adapted to the shape of the guide rail. It can be understood that by providing a first sliding member 110 (such as an arched guide rail) on at least one side (such as both sides) of the cover assembly 100, a stable sliding connection can be formed with the second sliding member 210 (such as a sliding groove) on the corresponding side of the box body 200, converting external force into a combined sliding and rotational motion of the cover assembly 100, realizing the smooth opening and closing of the receiving cavity 202. At the same time, the symmetrical arrangement on both sides improves the structural stability and avoids jamming or deformation caused by unilateral force.

[0039] The lid assembly 100 is mounted on the case body 200. For example, the lid assembly 100 is generally arc-shaped, and its lower part is rotatably connected to the case body 200. The movement of the lid assembly 100 is as follows: When the user applies external force to open the lid assembly 100 via the handle 141, in the initial movement phase, if the lid assembly 100 is within the range of 0°-50°, the first sliding members 110 on both sides of the lid assembly 100 (such as arched guide rails) slide along the second sliding members 210 (such as sliding grooves) of the case body 200 with a preset gradually changing curvature. The 38° chamfered structure at the end of the arched guide rail reduces the contact impact force, acting as a buffer. The elastic member 121 and the rotating arm 120 cooperate to maintain a constant preload, ensuring that the lid assembly 100 moves smoothly without wobbling. During the hovering triggering phase, when the cover assembly 100 moves to the range of 50°-60°, and the cover assembly 100 unfolds to 50°, the first sliding member 110 forms full contact with the supporting surface of the box body 200, the friction pair enters the working range, and the pre-tightening force is transmitted to the friction interface through the plug 123, generating a resistance torque that resists the gravity of the cover assembly 100; when the opening angle reaches 55°±5°, the resistance torque and the torque of the cover assembly 100 are dynamically balanced, realizing self-locking hovering without external force, that is, within the range of 50°-60°, the cover assembly 100 hovers when no external force is applied.

[0040] This application utilizes the sliding connection between the first sliding member 110 and the second sliding member 210 to allow the cover assembly 100 to slide relative to the box body 200. Combined with the rotation of the cover assembly 100, the cover assembly 100 can simultaneously complete sliding and rotating actions relative to the box body 200 under the action of external force, realizing the smooth opening and closing of the receiving cavity 202, improving the ease of operation. Compared with the traditional hinge structure, the combined sliding and rotating motion trajectory allows the cover assembly 100 to open without occupying extra space (such as hovering on the side or below the box body 200), better conforming to the contours of the vehicle body or installation environment, and adapting to the needs of compact space layout. In addition, this application does not require complex linkage or hinge mechanisms. Through the structure of the first sliding member 110 and the cover assembly 100 itself, the opening and closing function is achieved through the cooperation of sliding and rotation, reducing the number of parts, reducing assembly difficulty and production costs.

[0041] When the user applies external force to push the cover assembly 100, the cover assembly 100 slides and rotates relative to the box body 200 through the first sliding member 110 and the second sliding member 210, thereby opening or closing the receiving cavity 202.

[0042] In one possible implementation, the engineering machinery storage box in this application embodiment is combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the first sliding member 110 is an arched guide rail, and the second sliding member 210 is a sliding groove adapted to the arched guide rail. The arched guide rail and the sliding groove are slidably connected, and the bottom of the first sliding member 110 has a buffer member 111.

[0043] Specifically, the second sliding member 210 has a chamfer to form a buffer member 111. For example, the sliding end of the first sliding member 110 (arched guide rail) is machined with a 38° chamfer. The chamfer is located at the end of the guide rail and contacts the support surface of the side wall of the box body 200. The contact impact force is reduced by replacing the direct collision with the inclined contact. It also effectively reduces the impact and noise at the moment the cover assembly 100 is opened, and improves the operating feel and product durability.

[0044] The cover assembly 100 of this application forms a sliding connection with the sliding grooves on both sides of the box body 200 through the arched guide rails on both sides. When the cover is closed, the cover assembly 100 covers the top and sides of the box body 200.

[0045] In this embodiment, the user's pushing or pulling force is converted into the sliding and rotating motion of the cover assembly 100 by the cooperation of the arched guide rail and the slide groove, thereby realizing the smooth opening and closing motion of the cover assembly 100 relative to the box body 200.

[0046] The bottom of the first sliding member 110 has a buffer member 111. When the first sliding member 110 slides relative to the second sliding member 210 to open the receiving cavity 202, the buffer member 111 is used to abut against the support surface of the box body 200.

[0047] Furthermore, the first sliding member 110 can also have a specific cross-sectional shape. This application does not limit the structure of the cross-sectional shape. For example, the cross-section of the guide rail is T-shaped, with a width of 12.55 mm and a height of 8.5 mm. The guide rail can be integrally injection molded with the cover assembly 100. For example, the guide rail and the cover assembly 100 are made of a mixture of polypropylene (PP), ethylene propylene diene monomer (EPDM) rubber and 20% glass fiber (GF). The guide rail and the cover assembly 100 are directly processed into an integral structure through injection molding, rather than being assembled separately. In addition, a 38° chamfer is processed at the end of the arched guide rail.

[0048] The second sliding member 210 is a sliding groove with a gradually changing curvature that is adapted to the arched surface of the arched guide rail. The arched guide rail and the sliding groove are slidably connected. The curved surface of the arched guide rail and the curved surface of the sliding groove fit closely together, reducing the space occupied. Moreover, the arched guide rail adds anti-torsional force to the cover assembly 100 to prevent the cover assembly 100 from deforming during movement. The sliding groove with a gradually changing curvature can guide the movement trajectory of the cover assembly 100, avoiding jamming and shaking when the cover assembly 100 opens or closes.

[0049] In one possible implementation, the engineering machinery storage box in this application embodiment is combined with Figure 1 and Figure 2 As shown, at least one side of the cover assembly 100 has a rotating arm 120, which is rotatably connected to the box body 200. When the cover assembly 100 slides relative to the box body 200 to open the receiving cavity 202, the rotating arm 120 rotates relative to the box body 200 so that the cover assembly 100 is suspended in the open position.

[0050] The left and right sides of the cover assembly 100 are provided with integrally injection molded rotating arms 120. The rotating arms 120 have pre-embedded insert holes, and the cover assembly 100 is rotatably connected to the side wall of the box body 200 by a pin passing through the hole.

[0051] Among them, the hovering angle of the cover assembly 100 is greater than or equal to 45° and less than or equal to 65°.

[0052] When the cover assembly 100 slides relative to the box body 200 to open the receiving cavity 202 to a specific angle (45°-65°), during the rotation of the rotating arm 120 around the pin, the frictional resistance torque generated between the double arched guide rail on it and the supporting surface of the box body 200 is used to counteract the gravitational torque of the cover assembly 100, so that the cover assembly 100 can be suspended without external force within a specific angle range.

[0053] Understandably, the rotating arm 120 is part of the cover assembly 100. It is connected to the side wall of the box body 200 via a pin to form a rotation axis. At a specific angle, the contact area and normal pressure between the arched guide rail and the supporting surface of the box body 200 increase, forming a friction pair. The friction torque is balanced with the gravitational torque, thereby realizing the self-locking and hovering function of the cover assembly 100, freeing the user's hands, facilitating the storage and retrieval of items, and improving the convenience of use.

[0054] In one possible implementation, the engineering machinery storage box in this application embodiment is combined with Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, it also includes a connector 123. The rotating arm 120 has a connection hole 122. The connector 123 passes through the connection hole 122 and is connected to the rotating arm 120. The rotating arm 120 rotates relative to the box body 200 around the connector 123.

[0055] The connector 123 can be a pin, and there are two rotating arms 120. Each rotating arm 120 has a connecting hole 122. The pin passes through the connecting holes 122 of the two rotating arms 120 and connects to the box body 200, so that the rotating arm 120 can rotate relative to the box body 200.

[0056] In one possible implementation, the engineering machinery storage box in this application embodiment further includes an elastic element 121, one end of which is connected to the rotating arm 120, and the other end of which is connected to the box body 200.

[0057] For example, the elastic element 121 is a snap ring, and the other end of the elastic element 121 is connected to the side wall of the box body 200.

[0058] This application adds an elastic element 121, with one end connected to the rotating arm 120 and the other end connected to the box body 200. Its main function is to use the elastic force of the elastic element 121 to assist the rotating arm 120 in driving the cover assembly 100 to slide and rotate relative to the box body 200, thereby buffering the impact force during the opening and closing process.

[0059] In the initial stage of the first slider 110 sliding relative to the second slider 210 to open the receiving cavity 202, the buffer 111 is used to smoothly abut against the support surface at the end of the sliding groove of the box body 200, rather than impacting at a right angle.

[0060] In one possible implementation, the engineering machinery storage box in this application embodiment is combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the housing body 200 has a baffle 220 and a seal 230 inside. The baffle 220 is connected to the air inlet 201, and the air inlet 201 is connected to the receiving cavity 202. The baffle 220 is used to guide the airflow entering from the air inlet 201 into the receiving cavity 202. The seal 230 is provided at the air inlet 201.

[0061] The housing body 200 has a baffle 220 inside, which is connected to the air inlet 201. The air inlet 201 is connected to the receiving cavity 202. The baffle 220 is used to guide the airflow entering from the air inlet 201 into the receiving cavity 202.

[0062] For example, the baffle 220 is located inside the box body 200, near the air inlet 201. By guiding and distributing the airflow, it optimizes the flow field inside the box body 200, thereby improving the temperature uniformity of each area inside the storage box, and thus improving the cooling or heat preservation effect.

[0063] Alternatively, the baffle 220 may be located below the air inlet 201, and the air inlet 201 may be connected to the air outlet of the vehicle's air conditioning system. The baffle 220 is used to comb and guide the cooling airflow entering from the air inlet 201, so that it is evenly guided to various parts within the receiving cavity 202. Alternatively, the baffle 220 may have an air inlet 201.

[0064] The thickness of the baffle 220 can be uniformly set, or the thickness of the baffle 220 can increase sequentially from the direction towards the air inlet 201 to the direction away from the air inlet 201, so that the baffle 220 has a slope, further improving the air guiding effect, such as... Figure 5 As shown.

[0065] The sealing element 230 is located at the air inlet 201.

[0066] The sealing element 230 is made of closed-cell sponge material. Utilizing the good elasticity and sealing performance of closed-cell sponge, it seals the air inlet 201, effectively preventing cold air leakage and external hot air entry, maintaining a low-temperature environment inside the box body 200, and reducing energy consumption.

[0067] In addition, the seal 230 can also be disposed between the box body 200 and the cover assembly 100 to seal the gap between the box body 200 and the cover assembly 100 when the receiving cavity 202 is closed, thereby improving the sealing performance of the receiving cavity 202.

[0068] In one possible implementation, the engineering machinery storage box in this application embodiment is combined with Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it also includes a locking member 130, which is disposed on the side of the cover assembly 100 facing the box body 200. The box body 200 has a slot 240. When the receiving cavity 202 is closed, the locking member 130 is inserted into the slot 240. When the receiving cavity 202 is opened, the locking member 130 is disengaged from the slot 240.

[0069] The top of the cover assembly 100 is provided with a locking element 130. If the locking element 130 is a ball catch, the ball catch engages with the slot 240 on the box body 200. When the cover assembly 100 needs to close the box body 200, the cover assembly 100 moves relative to the box body 200 to the closed position, and the ball catch engages with the slot on the box body 200, thereby fixing the cover assembly 100 to rotate and cover the box body 200, thereby sealing and closing the box body 200.

[0070] Of course, the connection between the locking element 130 and the box body 200 can be replaced by other methods, and this application does not limit this, such as the locking element 130 being plugged into the box body 200.

[0071] In one possible implementation, the engineering machinery storage box in the embodiments of this application is combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the cover assembly 100 has an upper cover 140 and a lower cover 150 formed by bending. The extending direction of the upper cover 140 intersects the extending direction of the lower cover 150. At least one of the upper cover 140 and the lower cover 150 has a handle portion 141. When the receiving cavity 202 is closed, the upper cover 140 is located at the top of the receiving cavity 202 and the lower cover 150 is located at the side of the receiving cavity 202. When the receiving cavity 202 is opened, the upper cover 140 is located at the side of the receiving cavity 202.

[0072] The cover assembly 100 includes an upper cover 140 and a lower cover 150, which are integrally formed. The cover assembly 100 has a recess to form a handle 141, which can be used by the operator to grip the handle and apply force.

[0073] The upper cover 140 and the lower cover 150 are different parts of the same continuous component. Utilizing an integrated flip structure, they complete complex compound movements under the constraints of the first sliding member 110 (arched guide rail) and the second connecting member (sliding groove), saving space. When opened, the cover assembly 100 moves as a whole to the bottom of the box body 200 without affecting the front space of the cover assembly 100, maximizing the opening of the receiving cavity 202 for easy access to items.
