Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of a cargo box on a tricycle, and more specifically, the utility model relates to a cargo box for a tricycle. Background Art

[0002] With the increasing diversification of transportation and the public's growing pursuit of travel convenience, tricycles, with their economic and practical characteristics, have shown a wide range of application value in logistics, transportation, daily commuting and other fields. In particular, this type of tricycle cleverly incorporates a quick-release design, so that the cargo box loaded with goods can be easily placed on the tricycle frame between the two rear wheels of the tricycle, perfectly meeting the needs of users in different transportation scenarios. In the case of long-distance transportation, users only need to perform simple operations to firmly install the sturdy and durable cargo box on the tricycle. This design greatly reduces the physical burden of long-distance cargo transportation, making the transportation process more efficient and labor-saving. When faced with short-distance transportation or occasions that require flexible transportation, the advantages of this quick-release structure are even more obvious. With just a few steps, users can quickly remove the cargo box from the tricycle and instantly transform it into a portable mobile storage unit, making the last leg of the transportation process more efficient and labor-saving.

[0003] The cargo box of the tricycle can be folded and unfolded. When folding and unfolding the side panels of the cargo box, it usually takes a number of complicated steps and requires certain operating skills to fold and unfold the side panels. However, due to the complicated folding and unfolding steps of the existing cargo box, the user needs more time to operate the folding and unfolding of the side panels, and it is easy to make mistakes during the operation, resulting in irreversible damage to the cargo box, thereby losing the folding and unfolding functions, which seriously affects the user's experience. Utility Model Content

[0004] In order to solve one or more of the technical problems mentioned above, the utility model provides a cargo box for a tricycle, which can simplify the steps of folding and unfolding the cargo box, improve the efficiency and convenience of using the cargo box, prevent the cargo box from being irreversibly damaged, and increase the service life of the cargo box.

[0005] The utility model provides a cargo box, which includes:

[0006] Base plate;

[0007] a pair of first side panels hinged to the bottom panel and foldable relative to the bottom panel;

[0008] a pair of second side panels, which are hinged to the bottom panel and can be folded relative to the bottom panel, each of the second side panels includes a first elastic sub-panel arranged on both sides thereof and connected to the second side panel at one end, the first elastic sub-panel includes a guiding inclined surface, a top surface and a pressing inclined surface arranged away from the end connected to the second side panel and adjacent to each other; and

[0009] a pair of locking assemblies, which are arranged one-to-one with the first side panels, the locking assemblies comprising a connecting member arranged on the corresponding first side panel, a first locking member having one end hinged to the connecting member and the other end passing through the first side panel, and a second locking member having one end hinged to the connecting member and the other end passing through the first side panel;

[0010] Among them, the first locking piece or the second locking piece can pass through the corresponding guide inclined surface, the corresponding top surface and the corresponding pressing inclined surface on the first elastic sub-plate in sequence, and the first elastic sub-plate can undergo elastic deformation and accumulate deformation in the process of the first locking piece or the second locking piece passing through the guide inclined surface, and release the accumulated deformation in the process of passing through the pressing inclined surface to lock the first side plate and the second side plate.

[0011] By utilizing the characteristics of the first elastic sub-plate being able to undergo elastic deformation and being able to accumulate its deformation and convert the accumulated deformation into elastic force, the first side plate or the second side plate can be pressed against. The guide slope accumulates the deformation in the process of the first locking member or the second locking member rotating with the rotation of the end away from the connecting member as the first side plate rotates. The top surface no longer accumulates the deformation of the first elastic sub-plate when the first side plate and the bottom plate are perpendicular to each other. The pressing slope converts the deformation accumulated in the process of the first locking member or the second locking member rotating with the rotation of the end away from the connecting member as the first side plate rotates into elastic force, thereby pressing against the first locking member or the second locking member, thereby locking the first side plate with its corresponding second side plate. Through the specific setting of the first elastic sub-plate, the user only needs to turn the connecting member to unfold the first side plate and the second side plate of the luggage box to stand upright, which simplifies the operation steps of the luggage box and improves the efficiency and convenience of using the luggage box. The first elastic sub-plate can adaptively deform elastically to avoid hard contact between the first locking member or the second locking member and the second side plate due to improper operation by the user, thereby preventing irreversible damage to the second side plate or the first side plate, thereby improving the use of the cargo box.

[0012] Furthermore, the first elastic sub-plate can pass through the corresponding abutting slope, the corresponding top surface and the corresponding guide slope in sequence when the first locking member or the second locking member passes through the corresponding abutting slope, and undergo elastic deformation and accumulate deformation in the process of passing through the abutting slope, and release the accumulated deformation in the process of passing through the guide slope to unlock the first side panel and the second side panel.

[0013] Furthermore, the second side plate further includes a stopper extending vertically along both side edges thereof, and the first side plate further includes a stopper matching groove disposed on both side edges of its outer wall and matching with the stopper.

[0014] Furthermore, the first side plate also includes a first limiting protrusion disposed in the stop mating groove and extending in a direction away from the first side plate, and the second side plate also includes a limiting groove opened on the stop portion and mating with the first limiting protrusion.

[0015] Furthermore, the first limiting protrusion is contracted along its extension direction.

[0016] Furthermore, the first elastic sub-plate includes a first reinforcing rib disposed thereon and extending from one end thereof connected to the second side plate to an end away from the other end connected to the second side plate.

[0017] Furthermore, the first elastic sub-plate further includes a weight-reducing groove arranged on a side thereof away from the side connected to the second side plate.

[0018] Furthermore, the connecting member also includes a second elastic sub-plate arranged on its inner wall and connected to the connecting member at one end, and the first side plate also includes a second limiting protrusion arranged on its outer wall, and when the first side plate is locked with the corresponding second side plate, the second elastic sub-plate can be pressed against the second limiting protrusion.

[0019] Furthermore, the connecting member also includes an abutment portion arranged near one end of the first locking member and near one end of the second locking member, and the abutment portion can support one end of the first locking member and the connecting member hinged when the connecting member moves, and can support one end of the second locking member and the connecting member hinged when the connecting member moves.

[0020] Furthermore, the connecting member also includes a holding groove arranged thereon and used for holding. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0033] Figure 1 FIG. 2 shows a schematic diagram of the structure of the cargo box provided in this embodiment. Figure 2 FIG. 4 shows a top view of the cargo box provided in this embodiment, Figure 3 FIG. 4 shows an exploded view of the locking assembly 4 provided in this embodiment. Figure 1-Figure 3 As shown, the present embodiment provides a cargo box for a tricycle, the cargo box comprising a bottom plate 1, a pair of first side plates 2, a pair of second side plates 3 and a pair of locking assemblies 4. Each first side plate 2 is hinged to the bottom plate 1 and can be folded relative to the bottom plate 1. Each second side plate 3 is hinged to the bottom plate 1 and can be folded relative to the bottom plate 1, and each second side plate 3 comprises a first elastic sub-plate 31 arranged on both sides thereof and connected to the second side plate 3 at one end. The first elastic sub-plate 31 comprises a guide inclined surface 311, a top surface 312 and a pressing inclined surface 313 arranged at an end away from the end connected to the second side plate 3 and adjacent to each other. The locking assemblies 4 are arranged in a one-to-one correspondence with the first side plates 2, and each locking assembly 4 comprises a connecting member 41 arranged on the corresponding first side plate 2, a first locking member 42 having one end hinged to the connecting member 41 and the other end passing through the first side plate 2, and a second locking member 43 having one end hinged to the connecting member 41 and the other end passing through the first side plate 2. Among them, the first locking member 42 or the second locking member 43 can pass through the corresponding guide bevel 311, the corresponding top surface 312 and the corresponding clamping bevel 313 on the first elastic sub-plate 31 in sequence. The first elastic sub-plate 31 can undergo elastic deformation and accumulate deformation in the process of the first locking member 42 or the second locking member 43 passing through the guide bevel 311, and release the accumulated deformation in the process of passing through the clamping bevel 313 to lock the first side plate 2 and the second side plate 3.

[0034] When the luggage box needs to be changed from a folded state to an unfolded state, first, the second side panel 3 is moved to rotate around the hinge axis between the second side panel 3 and the bottom panel 1 in a direction away from the bottom panel 1. Subsequently, the connecting member 41 is moved along the first direction to force the end of the first locking member 42 or the second locking member 43 away from the connecting member 41 to move to a predetermined position along the second direction. Next, the first side panel 2 is moved to rotate around the hinge axis between the second side panel 2 and the bottom panel 1 in a direction away from the bottom panel 1, and at the same time, the end of the first locking member 42 or the second locking member 43 away from the connecting member 41 is driven to rotate along with the rotation of the first side panel 2, so that the end of the first locking member 42 or the second locking member 43 away from the connecting member 41 passes through the corresponding guide inclined surface 311. At this time, the first locking member 42 or the second locking member 43 squeezes the corresponding first elastic sub-plate 31, causing it to undergo elastic deformation and accumulate deformation. Then, when the end of the first locking member 42 or the second locking member 43 away from the connecting member 41 gradually moves to the top surface 312, at this time, the deformation of the first elastic sub-plate 31 increases to the maximum value, and the first side plate 2 and the bottom plate 1 are perpendicular to each other (i.e., relatively unfolded and upright). Finally, the connecting member 41 is moved along the second direction to force the end of the first locking member 42 or the second locking member 43 away from the connecting member 41 to move from the top surface 312 to the position of the inclined surface 313. At this time, the first elastic sub-plate 31 releases its accumulated deformation and converts it into elastic force to gradually press against the first locking member 42 or the second locking member 43, thereby achieving the locking of the first side plate 2 and the second side plate 3 adjacent thereto. The pair of first side plates 2 and the pair of second side plates 3 are interlocked in the above manner, so that the pair of first side plates 2 and the pair of second side plates 3 can be relatively unfolded and upright, thereby achieving the change of the luggage box from the folded state to the unfolded state.

[0035] By utilizing the characteristics of the first elastic sub-plate 31 that it can undergo elastic deformation and can accumulate its deformation and convert the accumulated deformation into elastic force, the first side plate 2 or the second side plate 3 can be pressed against. The guide slope 311 accumulates the deformation in the process of the first locking member 42 or the second locking member 43 rotating with the rotation of the first side plate 2 at one end away from the connecting member 41. The top surface 312 no longer accumulates the deformation of the first elastic sub-plate 31 when the first side plate 2 and the bottom plate 1 are perpendicular to each other. The pressing slope 313 converts the deformation accumulated in the process of the first locking member 42 or the second locking member 43 rotating with the rotation of the first side plate 2 at one end away from the connecting member 41 into elastic force, thereby pressing against the first locking member 42 or the second locking member 43, thereby locking the first side plate 2 with its corresponding second side plate 3. Through the specific configuration of the first elastic sub-plate 31, the user only needs to turn the connecting piece 41 to unfold the first side plate 2 and the second side plate 3 of the luggage case, which simplifies the operation steps of the luggage case and improves the efficiency and convenience of using the luggage case. In addition, by utilizing the characteristic that the first elastic sub-plate 31 can adaptively deform elastically, it is avoided that the first locking piece 42 or the second locking piece 43 and the second side plate 3 come into hard contact due to improper operation by the user, thereby preventing irreversible damage to the second side plate 3 or the first side plate 2, thereby improving the service life of the luggage case.

[0036] It should be noted that, in this embodiment, the first direction is a vertical downward direction, and the second direction is a reverse direction of the first direction. In other embodiments, the first direction and the second direction may also be two opposite directions of the horizontal direction, which is not specifically limited in this embodiment.

[0037] It should be noted that when the end of the first locking piece 42 or the second locking piece 43 away from the connecting piece 41 rotates with the rotating plate to a position relative to the first elastic sub-plate 31, the position of the end of the first locking piece 42 or the second locking piece 43 away from the connecting piece 41 corresponding to the guide bevel 311 is the predetermined position of the end of the first locking piece 42 or the second locking piece 43 away from the connecting piece 41.

[0038] Furthermore, the first locking member 42 or the second locking member 43 can also pass through the corresponding clamping bevel 313, the corresponding top surface 312 and the corresponding guide bevel 311 on the first elastic sub-plate 31 in sequence. The first elastic sub-plate 31 can undergo elastic deformation and accumulate deformation in the process of the first locking member 42 or the second locking member 43 passing through the clamping bevel 313, and release the accumulated deformation in the process of passing through the guide bevel 311 to unlock the first side panel 2 and the second side panel 3.

[0039] When the luggage box needs to be changed from the use state to the folded state, the connecting member 41 is first moved in the first direction to force the end of the first locking member 42 or the second locking member 43 away from the connection to move in the second direction on the abutting surface. At this time, the first elastic sub-plate 31 is deformed and accumulates deformation. Subsequently, when the end of the first locking member 42 or the second locking member 43 away from the connecting member 41 gradually moves to the top surface 312, the deformation of the first elastic sub-plate 31 increases to the maximum value. Next, the first side panel 2 is rotated around the hinge axis between the first side panel 2 and the bottom panel 1 in a direction close to the bottom panel 1, and the end of the first locking member 42 or the second locking member 43 away from the connecting member 41 rotates with the rotation of the first side panel 2, so that the end of the first locking member 42 or the second locking member 43 away from the connecting member 41 passes through the corresponding guide inclined surface 311. At this time, the first elastic sub-plate 31 releases its accumulated deformation and converts it into elastic force, squeezing the end of the first locking member 43 away from the connecting member 41, so as to force the end of the first locking member 43 away from the connecting member 41 to move along the inclined surface direction of the guide inclined surface 311. Finally, the second side panel 3 is rotated around the hinge axis between the first side panel 3 and the bottom panel 1 in a direction close to the bottom panel 1. In this way, the first side panel 2 and the second side panel 3 adjacent thereto are contacted and locked, and the pair of first side panels 2 and the pair of second side panels 3 are contacted and interlocked in the above manner, so that the pair of first side panels 2 and the pair of second side panels 3 can be folded relative to each other, thereby realizing the change of the luggage box from the unfolded state to the folded state.

[0040] Figure 4 Shows Figure 2 The cross-sectional view in the AA direction is as follows: Figure 4 Combined with Figure 1-Figure 3 As shown, the connecting member 41 further includes an abutment portion 412 disposed near one end of the first locking member 42 and one end of the second locking member 43, and the abutment portion 412 can lift up one end of the first locking member 42 hinged to the connecting member 41 when the connecting member 41 moves, and can lift up one end of the second locking member 43 hinged to the connecting member 41 when the connecting member 41 moves. This ensures that when the connecting member 41 needs to move along the second direction, it can drive one end of the first locking member 42 hinged to the connecting member 41 and one end of the second locking member 43 hinged to the connecting member 41 to move.

[0041] Furthermore, if Figure 4 Combined with Figure 1-Figure 3 As shown, the connecting member 41 also includes a holding groove 413 disposed thereon and used for holding, so that the user can move the connecting member 41 along the first direction or the second direction.

[0042] In this embodiment, the abutment portion 412 is a portion of the plate-shaped body of the connecting member 41 extending from the end of the connecting member 41 close to the first locking member 42, or a portion of the plate-shaped body of the connecting member 41 extending from the end close to the second locking member 43. In other embodiments, the abutment portion 412 may also be a plate-shaped object welded to the connecting member 41. This embodiment does not specifically limit this, and any structure that can achieve the above-mentioned abutment effect should be within the protection scope of the disclosed embodiment.

[0043] Figure 5 FIG. 2 shows a schematic diagram of the structure of the first side plate 2 provided in this embodiment. Figure 5 Combined with Figure 1-Figure 4 As shown, the connecting member 41 also includes a second elastic sub-plate 411 disposed on its inner wall and connected to the connecting member 41 at one end, and the first side plate 2 includes a second limiting protrusion 24 disposed on its outer wall. When the first side plate 2 and the corresponding second side plate 3 are locked, the second elastic sub-plate 411 can press against the second limiting protrusion 24. When the first side plate 2 and the second side plate 3 are in a relatively unfolded and upright state, the displacement of the connecting member 41 is limited, so that the connecting member 41 can remain stable even without external force, so that the first side plate 2 and the second side plate 3 can maintain a stable unfolded and upright state. And by utilizing the elastic deformation property of the second elastic sub-plate 411, when the first side plate 2 and the corresponding second side plate 3 are unlocked, the second elastic sub-plate 411 can be moved so that the second elastic sub-plate 411 no longer presses against the second limiting protrusion 24 to cooperate with the movement of the connecting member 41.

[0044] Specifically, the first side plate 2 includes a receiving groove 23 provided on its outer wall for the connector 41 to move, and a second reinforcing rib 25 provided on its outer wall and extending in a direction away from the first side plate 2 and crisscrossing each other, and the first locking member 42 and the second locking member 43 both pass through the second reinforcing rib 25 to strengthen the supporting strength of the first side plate 2. When the connector 41 moves to the top of the receiving groove 23 in the second direction, the top of the connector 41 abuts against the receiving groove 23, and the end of the second elastic sub-plate 411 not connected to the connector 41 abuts against the second limiting protrusion 24, so that the second elastic sub-plate 411 can abut against the second limiting protrusion 24 when the first side plate 2 is locked with the corresponding second side plate 3. When the connector 41 moves to the bottom of the receiving groove 23 in the first direction, the end of the second elastic sub-plate 411 not connected to the connector 41 no longer abuts against the second protrusion, so as to ensure that the connector 41 can move smoothly.

[0045] like Figure 5 As shown, the first limiting protrusion 22 is contracted along its extending direction, so as to facilitate the first limiting protrusion 22 to be inserted into the limiting groove 33 .

[0046] Figure 6FIG. 2 shows a schematic diagram of the structure of the second side plate 3 provided in this embodiment. Figure 6 Combined with Figure 1-Figure 5 As shown, the second side panel 3 further includes a stopper 32 extending vertically along the two side edges thereof, and the first side panel 2 further includes a stopper matching groove 21 provided at the two side edges of the outer wall thereof and matching with the stopper 32. The stopper matching groove 21 rotates as the first side panel 2 rotates around the hinge axis between the first side panel 2 and the bottom panel 1, so as to abut against the stopper 32 when the first side panel 2 rotates around the hinge axis between the first side panel 2 and the bottom panel 1 in a direction away from the bottom panel 1 to a state where the first side panel 2 is perpendicular to the bottom panel 1 (i.e., relatively unfolded and upright), thereby preventing the first side panel 2 from rotating too much, resulting in the inability of a pair of first side panels 2 and a pair of second side panels 3 to be surrounded with the bottom panel 1 to form a box.

[0047] In this embodiment, the stopper 32 is a portion of the second side plate 3 extending vertically along the two side edges of the second side plate 3. In other embodiments, the stopper 32 may also be a protrusion welded along the two side edges of the second side plate 3. This embodiment does not specifically limit this, and any structure that can achieve the above-mentioned stopper effect should be within the protection scope of the disclosed embodiment.

[0048] Further, refer to Figure 6 Combined with Figure 1-Figure 5 As shown, the first side panel 2 further includes a first limiting protrusion 22 disposed in the stopper matching groove 21 and extending in a direction away from the first side panel 2, and the second side panel 3 further includes a limiting groove 33 provided on the stopper portion 32 and matching with the first limiting protrusion 22. The first limiting protrusion 22 rotates as the first side panel 2 rotates around the hinge axis between the first side panel 2 and the bottom panel 1, so as to be inserted into the limiting groove 33 when the first side panel 2 rotates around the hinge axis between the first side panel 2 and the bottom panel 1 in a direction away from the bottom panel 1 to a state where the first side panel 2 is perpendicular to the bottom panel 1 (i.e., relatively unfolded and upright), thereby being plugged into the limiting groove 33, so as to provide guidance for the first side panel 2 and the second side panel 3, and provide a certain friction force, so that the first side panel 2 and the second side panel 3 are more stable in the unfolded state.

[0049] Preferably, if Figure 6 As shown, the second side plate 3 further includes third reinforcing ribs 34 which are arranged on the outer wall thereof and extend in a direction away from the second side plate 3 and are crisscrossed to enhance the supporting strength of the second side plate 3 .

[0050] like Figure 6 Combined with Figure 1 and Figure 5As shown, the first elastic sub-plate 31 includes a first reinforcing rib 314 arranged thereon and extending from one end connected to the second side plate 3 to an end connected to the second side plate 3 to provide support for the first elastic sub-plate 31 to prevent the first elastic sub-plate 31 from breaking when the deformation is too large, causing irreversible damage to the cargo box and losing the folding and unfolding function.

[0051] like Figure 6 Combined with Figure 1 and Figure 5 As shown, the first elastic sub-plate 31 also includes a weight-reducing groove 315 arranged on the side thereof away from the connection with the second side plate 3, so that the end of the first locking member 42 or the second locking member 43 away from the connecting member 41 can more easily squeeze the first elastic sub-plate 31, so that the user can save more effort when moving the connecting member 41 to squeeze the first elastic sub-plate 31.

[0052] In the above description of the present application, unless otherwise clearly specified and limited, the terms "fixed", "installed", "connected" or "connected" and the like should be understood in a broad sense. For example, with regard to the term "connection", it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. Therefore, unless otherwise clearly defined in the present application, those skilled in the art can understand the specific meanings of the above terms in the present utility model according to the specific circumstances.

[0053] According to the above description of the present application, those skilled in the art may also understand that the terms used below, such as "lower", "vertical", "top", "bottom", "inside", "outside" and other terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings of the present application, which are only for the purpose of facilitating the explanation of the scheme of the utility model and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operated in a specific orientation.
