[0001] This utility model relates to the field of storage box technology, specifically to a handle, box assembly, and toolbox. Background Technology
[0002] Boxes with storage functions, such as toy boxes and toolboxes, are usually equipped with handles to facilitate carrying. The handles are generally pivotally connected to the box. When it is necessary to move the box, the handle can be rotated to the high position, and the user can hold the handle to lift and move the box.
[0003] In existing technologies, the handle and the case are usually rigidly connected with a gap. When the user lifts the case, there is a tendency for noticeable swaying between the handle and the case, affecting the handling experience. In addition, when the case is lowered, the handle will slam into the case quickly under its own weight, producing an impact noise. Utility Model Content
[0004] The present invention aims to provide a handle structure, a box assembly, and a toolbox that can reduce the swing amplitude of the handle when it is lifted and improve the noise generated by the impact of the handle on the box body when it is lowered.

[0006] For rotatable mounting to the housing, the handle includes:
[0007] A handle body, comprising a gripping portion, a mounting portion, and a pivot member, wherein the pivot member is disposed on the mounting portion and is rotatably connected to the housing, such that the handle body has a first position and a second position, wherein in the first position the gripping portion is relatively far from the housing, and in the second position the gripping portion is relatively close to the housing; and,
[0008] A buffer element is sandwiched between the mounting portion and the housing, and the buffer element deforms under pressure at least when the handle body is in the first position.
[0009] Optionally, the buffer is at least disposed on the mounting surface of the handle body, the mounting portion having a first mounting side extending circumferentially along the pivot member, the first mounting side being used to rotate relative to the housing during the active stroke of the handle body switching from the first position to the second position, the first mounting side constituting a portion of the mounting surface, and the buffer covering at least a portion of the first mounting side.
[0010] Optionally, the grip portion has a second mounting side, which is used to gradually approach the housing during the movement of the handle body from the first position to the second position. The second mounting side constitutes a portion of the mounting surface, and the buffer covers at least a portion of the second mounting side.
[0011] Optionally, the first mounting side and the second mounting side are continuously arranged, and the buffer covering the first mounting side and the second mounting side is integrally arranged.
[0012] Optionally, during the rotational stroke of the handle body from the first position to the second position, the buffer has a pressure-bearing area that covers the first mounting side and is always under pressure and deformed, and the coverage of the pressure-bearing area corresponds to a rotation angle α of the pivot member that is greater than or equal to 10 degrees.
[0013] Optionally, a groove is formed on the handle body, the buffer is embedded in the groove, and the natural thickness of the buffer is greater than the depth of the groove.
[0014] Optionally, the natural thickness H2 of the buffer element is greater than or equal to 1 mm and less than or equal to 8 mm; and / or,
[0015] The depth D of the groove is greater than or equal to 0.5 mm and less than or equal to 7.5 mm; and / or,
[0016] The natural thickness of the buffer is H2, and the depth of the groove is D, where H2-D is greater than or equal to 0.3 mm and less than or equal to 2.5 mm.
[0017] To solve the above-mentioned technical problems, this utility model provides a housing assembly, comprising:
[0018] As mentioned above, the handle; and,
[0019] A housing having a limiting side formed thereon, the limiting side being arranged around the outer periphery of the first mounting side and forming a mounting gap with the first mounting side;
[0020] During the movement of the handle body switching between the first position and the second position, the buffer always fills at least part of the installation gap.
[0021] Optionally, the minimum dimension of the installation gap is H1, the natural thickness of the buffer is H2, H2-H1 is greater than or equal to 0.05H2, and less than or equal to 0.3H2; and / or,
[0022] The housing has a recessed cavity formed therein. When the handle body is in the second position, the handle body is accommodated in the recessed cavity.

[0026] The technical solution provided by this utility model has the following advantages:
[0027] This utility model provides a handle, a box assembly, and a toolbox. The box assembly includes a handle and a shell. The handle includes a handle body and a buffer. The handle body includes a grip portion, a mounting portion, and a pivot portion. The pivot portion is located on the mounting portion, and the handle is rotatably mounted on the shell via the pivot portion. The buffer portion is clamped between the mounting portion and the shell, serving to buffer and limit the movement of the handle. Specifically, when the handle body is in the first position, the buffer portion is clamped, requiring the handle body to overcome a certain resistance to move to the second position, thus being more stably held in the first position. When the user holds the grip portion and lifts the toolbox, the handle is less likely to wobble relative to the shell and / or the box body, thereby reducing or even eliminating the swing amplitude of the toolbox when the user lifts it, thus improving the user's carrying experience. When the user finishes carrying and puts down the handle, during the process of the handle body moving to the second position under the action of gravity or other external forces, the buffer portion again plays a good buffering role, slowing down the falling speed of the handle, thereby reducing the noise of the handle colliding with the shell.

Detailed Implementation
[0045] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.
[0046] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0047] Please see Figures 1 to 14 This utility model provides a handle 101, a box assembly 100, and a storage box. The box assembly 100 can be the storage box itself or a component belonging to the storage box. The storage box is a box product with a storage cavity for storing items and can be easily lifted and moved. Depending on its function, the storage box can specifically be a toolbox, toy box, clothing storage box, etc. Preferably, in this embodiment, please refer to... Figure 1 The storage box is toolbox 1, which is a product specifically designed for storing tools and is easy to move. For ease of explanation, toolbox 1 will be used as an example in the following text.
[0048] In this embodiment, please refer to Figures 2 to 5 The housing assembly 100 includes a handle 101 and a housing 102, wherein the handle 101 is rotatably mounted on the housing 102. In an optional embodiment, the housing assembly 100 serves as the toolbox 1 itself, for example, the housing 102 has an open cavity for storing tools, the handle 101 is fitted onto the housing 102, and the housing assembly 100 may further include a cover that covers the open side of the housing 102.
[0049] In another embodiment, such as Figure 1 As shown, the housing assembly 100 is used as a component of the toolbox 1. Specifically, the toolbox 1 includes a main body 200 and the aforementioned housing assembly 100. The main body 200 has a cavity for storing tools and an open side communicating with the cavity. The housing assembly 100 is constructed as a lid-like structure and is integrally and closably fitted onto the open side of the main body 200. Specifically, the housing 102 is mounted on the main body 200 in a manner such as being detachable, rotatable, or slidable, thereby having a closed position with the lid on the open side and an open position away from the open side. That is to say, when the user needs to lift the toolbox 1, the housing assembly 100 needs to be placed on the main body 200 first, so as to prevent tools inside the cavity from falling out when moving the toolbox 1.
[0050] In another embodiment, the box assembly 100 can serve as both the toolbox itself (i.e., the box assembly 100 can store items) and the lid of the main body 200. This configuration allows for a larger cavity in the main body 200 to store larger items, such as the bodies of power or manual tools; a smaller cavity can be provided in the shell 102 to store smaller tool parts such as screws and nuts, achieving categorized storage. This not only further subdivides the storage space and improves the convenience of storage operations, but also utilizes the space occupied by the handle 101, allowing the toolbox 1 to store more tools and accessories within the same size, thus improving space utilization.
[0051] Based on the above embodiments, please continue to refer to... Figures 6 to 8 The handle 101 includes a handle body 10 and a buffer member 20. The handle body 10 includes a grip portion 11, a mounting portion 12, and a pivot member 13. The grip portion 11 and the mounting portion 12 are integrally formed or assembled together. The grip portion 11 is used for the user to hold, and the mounting portion 12 is used to connect with the housing 102, so that the handle 101 and the housing 102 are assembled to form a box assembly 100. In an optional embodiment, the handle body 10 may be generally U-shaped, with the mounting portions 12 located at both ends of the grip portion 11.
[0052] When a user intends to carry the toolbox 1, they can grasp the grip 11 to rotate and lift the handle 101, making it convenient for the user to carry the toolbox 1. A pivot member 13 is provided on the mounting portion 12. Specifically, the pivot member 13 can be fixed to the mounting portion 12 or integrally formed with the mounting portion 12. A pivot fitting member is provided on the housing 102 corresponding to the pivot member 13. The pivot member 13 and the pivot fitting member cooperate with each other so that the handle body 10 is rotatably connected to the housing 102. Thus, the handle 101 has a first position and a second position, such as... Figure 2 and Figure 3 As shown, in the first position, the grip portion 11 is relatively far away from the housing 102, while in the second position, the grip portion 11 is relatively close to the housing 102.
[0053] The specific structure of the pivot member 13 and the pivot mating member can be designed according to needs. For example, they can be a rotating shaft and pivot hole 50, a convex shaft and a sleeve, etc., that are rotatably assembled together. In this embodiment, for example... Figure 6 and Figure 7As shown, the pivot member 13 is a rotating shaft protruding on one side of the mounting part 12, and the pivot fitting can be set as a pivot hole 50 formed on the housing 102. It can be understood that in optional embodiments, the pivot member 13 can also be set as a pivot hole and the pivot fitting can be set as a pivot shaft. Other optional embodiments can refer to similar rotating connection structures in the prior art, which will not be described in detail here.
[0054] In this embodiment, to ensure strength, both the handle body 10 and the housing 102 are made of relatively strong materials, such as plastic or metal. To achieve the aforementioned pivoting fit, the handle body 10 and the housing 102 are rigidly connected with a gap. The applicant found that during the process of the user lifting and moving the toolbox 1, a relatively large amount of relative rotation easily occurs between the handle body 10 and the housing 102, resulting in a noticeable shaking sensation when carrying the toolbox 1, affecting the carrying experience. Furthermore, when the toolbox is lowered, the handle body 10, under its own weight, will quickly slam into the housing 102, producing an impact noise.
[0055] To address the aforementioned issues, this embodiment is described in conjunction with further reading. Figures 8 to 11 The handle 101 also includes a buffer 20, wherein the buffer 20 should be made of a material with good elasticity or elastoplasticity, such as silicone, rubber, foam, etc. The buffer 20 is sandwiched between the mounting part 12 and the housing 102 so that when the handle body 10 is at least in the first position, the buffer 20 is deformed under pressure, specifically, the buffer 20 undergoes elastic deformation or elastoplastic deformation.
[0056] It is understood that the mounting part 12 and the housing 102 are fitted with a clearance, thereby rotatably connecting the handle body 10 and the housing 102. That is, there is a gap between the mounting part 12 and the housing 102. During the movement of the handle body 10 between the first position and the second position, the handle body 10 and the housing 102 on both sides of the gap move relative to each other. The buffer 20 can be installed on the handle body 10 or on the housing 102. In this embodiment, the buffer 20 fills at least part of the gap so that during the movement of the handle body 10 from the first position to the second position, the buffer 20 is compressed and undergoes elastic or elastoplastic deformation, hindering the relative movement between the handle body 10 and the housing 102, and playing a buffering and limiting role for the handle body 10. Specifically, when the handle body 10 is in the first position, the buffer 20 is clamped, requiring the handle body 10 to overcome a certain resistance to move to the second position, thus being more stably held in the first position. When the user holds the grip part 11 to lift the toolbox 1, the handle 101 is less likely to wobble relative to the housing 102 and / or the main body 200, thereby reducing or even eliminating the swing amplitude of the toolbox 1 when the user lifts it, thus improving the user's carrying experience. When the user finishes carrying and puts down the handle 101, during the process of the handle body 10 moving to the second position under the action of gravity or other external forces, the buffer 20 again plays a good cushioning role, slowing down the falling speed of the handle 101, thereby reducing the noise of the handle 101 colliding with the housing 102.
[0057] It should be noted that in this embodiment, the buffer 20 is not disposed between the pivot 13 and the pivot mating part, but between the mounting part 12 and the housing 102. This avoids the complexity and difficulty in assembly of the pivot structure between the handle 101 and the housing 102, and also minimizes the adverse effects of the buffer 20 on the switching movement of the handle 101 between the first and second positions, resulting in smoother rotation.
[0058] In one optional embodiment, the buffer member 20 has a certain width in the axial direction, which can provide a good buffering effect. It should be noted that in this utility model, the axial direction is the direction of extension of the rotation axis of the pivot shaft, and the radial and circumferential directions are defined with reference to the axial direction.
[0059] In another alternative implementation, such as Figures 11 to 14 As shown, the buffer member 20 has a certain length in the circumferential direction. In this way, the buffer member 20 is easier to install, and the influence of the buffer member 20 on the rotational engagement of the pivot member 13 and the pivot mating member is dispersed over a larger circumferential range, resulting in a more stable structure.
[0060] In the preferred embodiment, please refer to Figure 7 and Figure 8A buffer element 20 is disposed on the handle body 10, and the buffer element 20 is at least disposed on the mounting surface 15 of the handle body 10. The method of fixing the buffer element 20 to the mounting surface 15 is not limited, for example, it can be fixed to the mounting surface 15 by means of bonding, snap-fitting, heat pressing, etc. It should be noted that, in this embodiment, the mounting surface 15 is part of the outer surface of the handle body 10, and when the handle body 10 is in the second position, the mounting surface 15 is disposed opposite to the outer surface of the housing 102.
[0061] Specifically, please refer to the following: Figure 8 , Figures 11 to 14 The mounting portion 12 has a first mounting side 151 extending circumferentially along the pivot 13. When the handle body 10 is in the first position, the first mounting side 151 faces the housing 102. During the movement of the handle body 10 from the first position to the second position, the first mounting side 151 rotates relative to the housing 102. The first mounting side 151 forms part of the mounting surface 15. The buffer member 20 covers at least part of the first mounting side 151.
[0062] Specifically, please refer to the following: Figure 6 A limiting side 31 is formed on the housing 102, which is arranged around the outer periphery of the first mounting side 151 and forms a mounting gap 40 between the limiting side 31 and the first mounting side 151. During the movement of the handle body 10 switching between the first position and the second position, the buffer 20 always fills at least part of the mounting gap 40. In this way, the buffer 20 is clamped in the arc-shaped space formed between the outer periphery of the mounting part 12 and the housing 102, which can play an effective buffering and limiting role. As the handle body 10 rotates, the buffer 20 can be gradually pressed and is not easy to fall off.
[0063] Based on the previous embodiment, please refer to the following: Figure 10 and Figure 14 The minimum dimension of the installation gap 40 is H1. It should be noted that H1 refers to the minimum radial distance between the first mounting side 151 and the limiting side 31. The natural thickness of the buffer member 20 is H2. Here, H2 refers to the radial dimension of the buffer member 20 at the aforementioned minimum distance when there is no external force and no compressive deformation. H2-H1 is greater than or equal to 0.05H2 and less than or equal to 0.3H2. Within this range, the buffer member 20 has a reasonable amount of deformation when subjected to pressure. Within this range, the handle 101 will not be difficult to rotate due to excessive thickness of the buffer member 20, nor will the buffer member 20 be difficult to recover from plastic deformation. At the same time, it avoids the situation where the buffer member 20's deformation is too small, thus failing to provide the required buffering and limiting effect.
[0064] Preferably, a cavity 30 is formed on the housing 102. When the handle body 10 is in the second position, the handle body 10 is accommodated in the cavity 30 and does not exceed the outer contour of the housing 102 adjacent to the cavity 30. The inner wall of the cavity 30 is partially arranged around the outer periphery of the first mounting side 151 to form the aforementioned limiting side 31. In this embodiment, the housing 102 is constructed to have a shape capable of accommodating the handle 101. That is, when the handle 101 is in the second position, the box assembly 100 and / or toolbox 1 have a flat outer contour and a compact structure, thereby occupying a smaller overall size, making it easier to store, and also more aesthetically pleasing.
[0065] Preferably, please continue reading. Figure 8 The grip portion 11 has a second mounting side 152, which is positioned facing the housing 102 when the handle body 10 is in the second housing 102, and gradually approaches the housing 102 during the movement of the handle body 10 from the first position to the second position. The second mounting side 152 constitutes a mounting surface 15, and the buffer 20 covers at least a portion of the second mounting side 152. Thus, when the handle body 10 switches from the first position to the second position, the buffer 20 covering the second mounting side 152 will collide with the housing 102 instead of the handle body 10, transforming the collision between the two rigid components into a collision between the flexible buffer 20 and the rigid housing 102, thereby effectively reducing the noise when the handle 101 falls. In addition, the grip portion 11 is covered with the buffer 20, which also allows the user's hand to contact the soft and elastic surface of the buffer 20 when holding the grip portion 11 to lift the toolbox 1, thereby providing the user with a good grip experience.
[0066] It is understood that, in the preferred embodiment, the buffer 20 is not limited to covering only the first mounting side 151 and the second mounting side 152. The buffer 20 can also cover the entire grip part 11, or it can be further attached to the side of the grip part 11 opposite to the second mounting side 152, thereby providing the user with a better grip experience.
[0067] Based on the above embodiments, regardless of whether the buffer 20 covers the first mounting side 151 and / or the second mounting side 152, the buffer 20 can be configured to completely cover the first mounting side 151 and / or the second mounting side 152, or it can be configured to only partially cover the first mounting side 151 and / or the second mounting side 152. Furthermore, the buffer 20 can also have a solid structure or a perforated structure.
[0068] In an optional embodiment, the first mounting side 151 and the second mounting side 152 are continuously arranged, and the buffer member 20 covering the first mounting side 151 and the second mounting side 152 is integrally arranged. This facilitates the installation and manufacturing of the buffer member 20, as well as its assembly with the handle body 10.
[0069] Preferably, please refer to Figure 12 During the rotational stroke of the handle body 10 from the first position to the second position, the buffer 20 has a pressure-bearing area 21 that covers the first mounting side 151 and is always under pressure and deforms, such as Figure 12 As shown, the coverage area of the pressure zone 21 corresponds to a rotation angle α of the pivot 13 that is greater than or equal to 10 degrees. It can be understood that during the movement of the handle 101 repeatedly rotating between the first position and the second position, the edge of the buffer 20 may lift up due to the relative movement between the first mounting side 151 and the limiting side 31. Therefore, the buffer 20 is set to be constantly compressed in a portion of the area surrounding the first mounting side 151. As shown, when the handle body 10 is in the first position, the area of the buffer 20 that is compressed is the smallest, and during the process of the handle body 10 switching to the second position, the area of the buffer 20 that is compressed gradually increases. Thus, no matter whether the handle body 10 moves from the first position to the second position or from the second position to the first position, the pressure zone 21 ensures that the edge of the buffer 20 will never lift up.
[0070] In an optional embodiment, the buffer 20 is installed as follows: Figure 9 and Figure 10 As shown, a groove 14 is formed on the handle body 10, and a buffer member 20 is embedded in the groove 14, with the natural thickness of the buffer member 20 being greater than the depth of the groove 14. Preferably, the bottom surface of the groove 14 forms a mounting surface 15. When the buffer member 20 is attached to the mounting surface 15, the buffer member 20 partially protrudes from the groove 14, thereby allowing it to deform under pressure. In this embodiment, the groove 14 can be integrally formed during the molding of the handle body 10, or different components can be assembled to form the groove 14. When manufacturing the handle 101, the handle body 10 can be provided first, and then the sheet-like buffer member 20 can be attached to the bottom surface of the groove 14 by means of, for example, adhesive bonding, thereby assembling the handle 101. The groove 14 facilitates accurate positioning when assembling the buffer member 20 and the handle body 10, and the edge of the buffer member 20 in the width direction is protected by the groove 14, making it less prone to warping after prolonged use. In addition, the design of the groove 14 provides a certain amount of clearance for the buffer 20. When the installation gap 40 or the gap is particularly small, the natural thickness of the buffer 20 does not need to be designed to be too thin, which makes it easier to manufacture.
[0071] Based on the previous embodiment, specifically, the natural thickness H2 of the buffer 20 is greater than or equal to 1 mm and less than or equal to 8 mm; and / or, the depth D of the groove 14 is greater than or equal to 0.5 mm and less than or equal to 7.5 mm; and / or, the natural thickness of the buffer 20 is H2, the depth of the groove 14 is D, and H2-D is greater than or equal to 0.3 mm and less than or equal to 2.5 mm. Thus, the buffer 20 has dimensions that are easy to manufacture, provides a sufficiently ideal cushioning effect, and the size of the installation gap 40 is appropriate, making the toolbox 1 aesthetically pleasing.
[0072] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
