Description

Technical Field

[0001] This application relates to the field of rigid trolley case technology, and in particular to a rigid trolley case. Background Technology

[0002] A rigid rolling suitcase is a type of luggage with a pull handle and wheels. It is widely used due to its ease of use.

[0003] In related technologies, to improve the convenience of using rigid trolley cases, the opening method of the rigid trolley case is set to a top opening. The top opening is rotatably connected to the side wall of the rigid trolley case with the pull rod. When it is necessary to open, the top opening is flipped over to open the top opening.

[0004] However, in related technologies, flip-top covers often have two drawbacks after opening: First, the cover usually has holes to allow for the pull handle, affecting its aesthetics and integrity. Second, the cover is horizontal or nearly horizontal, making it easy for items to fall off and hindering easy access. Utility Model Content

[0005] This application provides a rigid trolley case that allows for easy loading, unloading, and display of items after the lid is opened.

[0006] According to one aspect of the embodiments of this application, a rigid trolley case is provided, comprising:

[0007] The box body has a pull rod on its first side panel and a first opening between its second side panel and the first top panel; the second side panel is opposite to the first side panel.

[0008] The cover is positioned over the first opening and is rotatably connected to the edge of the first top plate facing away from the first side plate. The inner side of the second top plate of the cover has a protrusion located at the edge of the second top plate connected to the first top plate.

[0009] In one embodiment, the cover includes:

[0010] The third side panel is connected to the end of the second top panel away from the first top panel; when the cover is installed over the first opening, the third side panel extends toward the bottom panel of the box.

[0011] The fourth side panel connects the second top panel and the third side panel;

[0012] The fifth side panel connects the second top panel and the third side panel, and the fifth side panel is opposite to the fourth side panel;

[0013] The protrusion connects the fourth side plate and the fifth side plate.

[0014] In one embodiment, the protrusion extends beyond the inner side of the second top plate by a length less than the length of the third side plate.

[0015] In one embodiment, the housing includes a first part and a second part, the first part including a portion of a first side panel and a second side panel, and the second part including a first top panel and another portion of the first side panel;

[0016] The first part and the second part are a single unit.

[0017] In one embodiment, the housing includes a first part and a second part, the first part including a portion of a first side panel and a second side panel, and the second part including a first top panel and another portion of the first side panel;

[0018] The first part and the second part are separate components, and the first part and the second part are fixedly connected.

[0019] In one embodiment, the first top plate is provided with a handle located in the middle of the first top plate.

[0020] In one embodiment, along the arrangement direction of the first side plate and the second side plate, the length of the second top plate is greater than or equal to the length of the first top plate.

[0021] In one embodiment, the cross-sectional shape of the edge cover includes any one of a triangle, a rectangle, or a trapezoid.

[0022] In one embodiment, the rigid rolling case further includes:

[0023] The cover is used to cover the edge of the first opening and the edge of the cover.

[0024] In one embodiment, the box is provided with a partition, one end of which is rotatably connected to the inner wall of the box, and the other end of which is detachably connected to the inner wall of the box.

[0025] The rigid trolley case provided in this application embodiment has a first opening between a second side panel opposite to the first side panel and a first top panel of the case body. A lid covers the first opening, and the lid is foldably connected to the edge of the first top panel facing away from the first side panel. Thus, there is a certain distance between the edge of the first opening on the first top panel (i.e., the edge of the first top panel facing away from the first side panel) and the first side panel. When the lid is flipped open relative to the first top panel, the first top panel provides clearance, creating a certain distance or gap between the lid and the trolley rod. This avoids interference between the lid and the trolley rod when the lid is flipped open, facilitating the opening of the lid. The lid can be opened normally without the need for clearance holes, improving the integrity of the rigid trolley case.

[0026] In addition, a protrusion is provided on the inner side of the second top plate of the cover, and the protrusion is located at the edge of the end where the second top plate is connected to the first top plate; in this way, after the cover is flipped open, the protrusion can protrude from the top of the box and form a blocking structure on the second top plate. At this time, the items taken out of the box can be prevented on the second top plate and blocked by the protrusion, which makes it convenient to place and display the items.

[0027] In addition, when it is necessary to access or place items at the bottom or lower part of the box, items at the top of the box can be temporarily placed on the lid. The protruding part can hold the items in place stably, making it easier to access and organize the items inside the box. Attached Figure Description

[0054] Reference Figure 1 As shown, Figure 1 This is a schematic diagram of the overall structure of a rigid trolley case provided in some embodiments of this application. Some examples of embodiments of this application provide a rigid trolley case. The rigid trolley case may include a case body 10.

[0055] In some examples, the enclosure 10 can be a rigid shell enclosure 10. The enclosure 10 can be made of any one or more of the following materials: polycarbonate (PC), polyvinyl chloride (PVC), polypropylene (PP), acrylonitrile-butadiene-styrene copolymer (ABC) and PC, or aluminum alloy.

[0056] It is understood that in the embodiments of this application, the specific material of the box 10 is only shown as some specific examples and is not intended to limit the specific material of the box 10.

[0057] In some examples, refer to Figure 2 As shown, the figure is along Figure 1 A sectional view along line AA. The housing 10 may have a first side plate 11. The first side plate 11 may be arranged in the vertical direction.

[0058] In some examples, refer to Figure 2 As shown, the first side panel 11 may be equipped with a pull rod 20. The pull rod 20 is telescopic relative to the box body 10. When it is necessary to pull the box body 10, the pull rod 20 can be pulled out and the box body 10 can be pulled. When it is not necessary to pull the box body 10, the pull rod 20 can be stored in the first side panel 11, reducing the space occupied by the pull rod 20. In addition, storing the pull rod 20 in the first side panel 11 can also protect the pull rod 20.

[0059] In some examples, the housing 10 may have a base plate 140. The base plate 140 may be attached to the bottom end of the first side plate 11.

[0060] In some examples, the base plate 140 may be equipped with rollers. The rollers can rotate relative to the housing 10, so that when the housing 10 is pulled, the rollers can roll on the ground, which can convert the sliding friction between the housing 10 and the ground into rolling friction, making it easier to pull the housing 10.

[0061] In some examples, refer to Figure 1 and Figure 2 As shown, the housing 10 may have a first top plate 130. The first top plate 130 may be connected to the top of the first side plate 11.

[0062] Figure 3 This is a schematic diagram of a rigid trolley case with the lid in an open state, provided in some embodiments of this application.

[0063] In some examples, refer to Figure 2 and Figure 3 As shown, the box 10 may have a second side panel 12, which may be disposed opposite to the first side panel 11. That is, a receiving space 101 can be formed between the first side panel 11 and the second side panel 12 within the box 10. Items can be placed within the receiving space 101 of the box 10.

[0064] Specifically, refer to Figure 3 As shown, the housing 10 may have a left side panel 150 and a right side panel 160. The left side panel 150 and the right side panel 160 may be arranged opposite each other. It should be noted here that, referring to... Figure 3 As shown, along Figure 3 The direction indicated by the x-axis can be the left-right direction of the housing 10. The left side panel 150 can be connected between the first side panel 11 and the second side panel 12. The right side panel 160 can be arranged opposite to the left side panel 150 and connected between the first side panel 11 and the second side panel 12. That is, the first side panel 11, the second side panel 12, the bottom panel 140, the first top panel 130, the left side panel 150, and the right side panel 160 together form the receiving space 101 inside the housing 10.

[0065] In some examples, the storage space 101 can be used to place items such as luggage, documents, and electronic products. It is understood that the storage space 101 can also be used to place other items. The items placed in the storage space 101 in this embodiment are only shown as specific examples and are not intended to limit the items that can be placed in the storage space 101.

[0066] In some examples, refer to Figures 3-7 As shown, Figure 4 This is a schematic diagram of another overall structure of a rigid trolley case provided in some embodiments of this application. Figure 5 This is another structural schematic diagram of a rigid trolley case with the lid in an open state, provided in some embodiments of this application. Figure 6This is another overall structural schematic diagram of a rigid trolley case provided in some embodiments of this application. Figure 7 This is another structural schematic diagram of a rigid trolley case with the lid in an open state, provided in some embodiments of this application.

[0067] In some examples, the housing 10 can be integrally molded using injection molding. This simplifies the manufacturing process of the housing 10.

[0068] In some examples, the box 10 can be divided into two parts. The two parts of the box 10 can be formed by vacuum forming, and then the two parts of the box 10 can be fixedly connected to form a complete box 10 structure.

[0069] For example, refer to Figure 3 As shown, the housing 10 may include a first part 10a and a second part 10b. The first part 10a and the second part 10b may be formed by vacuum forming or injection molding, respectively, and then cut into the first part 10a and the second part 10b in a regular manner according to actual needs. Finally, the first part 10a and the second part 10b are fixedly connected by alloy frames or other metal frames, as well as fasteners such as rivets, thereby constructing a complete housing 10.

[0070] In some examples, when the cover 30 is rectangular or trapezoidal, refer to Figures 4-7 , Figure 12 and Figure 15 As shown, the housing 10 can be divided into a first part 10a and a second part 10b along the extension line in the direction of the dotted line in the figure. The first side panel 11, the left side panel, and the right side panel can each include two parts. In a specific configuration, each part can be formed using a one-time vacuum forming or injection molding method as described in the foregoing embodiments of this application, and then connected by alloy or metal frames, rivets, etc.

[0071] In some examples, refer to Figure 3 As shown, a first opening 102 is formed between the second side plate 12 and the first top plate 130. In some examples, a portion of the end of the first top plate 130 away from the first side plate 11 can be cut off, and portions of the top of the second side plate 12, the left side plate 150, and the right side plate 160 can also be cut off to form the first opening 102. For example, the size of the first opening 102 can be determined according to actual needs, as well as the length that the first top plate 130 and the second side plate 12 need to be cut; a line can be drawn connecting the determined positions of the second side plate 12 and the first top plate 130, and then cuts can be made along the connecting line to form the first opening 102.

[0072] In some examples, the first opening 102 may be connected to the receiving space 101. That is, an item can be taken out of the receiving space 101 through the first opening 102, or an item can be placed into the receiving space 101 through the first opening 102.

[0073] In some examples, refer to Figures 1-7 As shown, a rigid trolley case may include a lid 30. The material of the lid 30 may be the same as, similar to or similar to the material of the case body 10. For details, please refer to the detailed description of the case body 10 in the foregoing embodiments of this application. This application will not repeat the details in this embodiment.

[0074] In some examples, the cover 30 may be placed over the first opening 102. That is, the cover 30 may close the first opening 102, thereby enclosing the item within the receiving space 101.

[0075] In some examples, refer to Figures 1-7 As shown, the cover 30 is rotatably connected to the first top plate 130 at one end opposite to the first side plate 11. For example, when the cover 30 closes the first opening 102, the cover 30 can be flipped relative to the first top plate 130. Figure 1 and Figure 2 The state shown closes the first opening 102. When it is necessary to open the first opening 102, the cover 30 can be flipped in the direction indicated by arrow a in section 3, so that the cover 30 is flipped to... Figure 3 The state shown.

[0076] In some examples, the cover 30 can be rotatably connected to the first top plate 130. For example, a pivot can be provided on one of the first top plate 130 and the cover 30, and a shaft hole can be provided on the other of the first top plate 130 and the cover 30; the pivot passes through the shaft hole, thereby enabling the cover 30 to be flipped relative to the first top plate 130.

[0077] In some examples, the cover 30 can be connected to the first top plate 130 by a hinge, so that the cover 30 can be flipped relative to the first top plate 130.

[0078] In some examples, the cover 30 and the first top plate 130 can be connected by a flexible connector, allowing the cover 30 to be flipped relative to the first top plate 130. For example, the cover 30 and the first top plate 130 can be connected by a leather piece, a woven strap, or a rubber sheet.

[0079] It is understood that in the embodiments of this application, the type of connection structure between the cover 30 and the first top plate 130 is only shown as some specific examples and is not intended to limit the specific type of connection structure.

[0080] In some examples, a connection structure may be provided between the cover 30 and the first top plate 130. A connection structure may be provided along the left-right direction of the first top plate 130 (e.g., ...). Figure 3 The middle part (in the direction shown by the x-axis).

[0081] In some examples, multiple connection structures can be provided between the cover 30 and the first top plate 130. For example, two connection structures can be provided. Multiple connection structures can be arranged at intervals along the left and right directions of the first top plate 130.

[0082] In some examples, refer to Figure 1 and Figure 2 As shown, the cover 30 may have a second top plate 310. When the cover 30 closes the first opening 102, the second top plate 310 may be parallel or approximately parallel to the first top plate 130.

[0083] In some examples, refer to Figure 3 As shown, a protrusion 311 may be provided on the inner side of the second top plate 310. The inner side of the second top plate 310 may refer to the side of the second top plate 310 facing the receiving space 101 when the cover 30 is in the state of closing the first opening 102.

[0084] In some examples, the protrusion 311 may be integral with the second top plate 310.

[0085] In some examples, the processing and forming method of the cover 30 may be the same as, similar to or similar to that of the box 10. For details, please refer to the detailed description of the box 10 in the foregoing embodiments of this application. This application will not repeat the details in this embodiment.

[0086] In some examples, refer to Figure 3 As shown, the protrusion 311 can be located at the edge of the second top plate 310 where it connects to the first top plate 130. When the cover 30 is in the open state, the protrusion 311 can be located at the edge of the second top plate 310 away from the first side plate 11.

[0087] The rigid trolley case provided in this application embodiment has a first opening 102 between the second side plate 12, which is opposite to the first side plate 11, and the first top plate 130 of the case body 10. A cover 30 is placed over the first opening 102, and the cover 30 is foldably connected to the edge of the first top plate 130 facing away from the first side plate 11. Thus, the edge of the first opening 102 on the first top plate 130 (i.e., the edge of the first top plate 130 facing away from the first side plate 11) is a certain distance from the first side plate 11. When the cover 30 is flipped open relative to the first top plate 130, the first top plate 130 provides clearance, creating a certain distance or gap between the cover 30 and the pull rod 20. This avoids interference between the cover 30 and the pull rod 20 when the cover is flipped open, facilitating the opening of the cover 30. The cover 30 can be opened normally without the need for clearance holes, improving the integrity of the rigid trolley case.

[0088] In addition, a protrusion 311 is provided on the inner side of the second top plate 310 of the cover 30. The protrusion 311 is located at the edge of the second top plate 310 connected to the first top plate 130. In this way, after the cover 30 is flipped open, the protrusion 311 can protrude from the top of the box 10 and form a blocking structure on the second top plate 310. At this time, the items taken out from the box 10 can be prevented on the second top plate 310 and blocked by the protrusion 311, which makes it convenient to place and display the items.

[0089] In addition, when it is necessary to take out or put in items at the bottom or lower part of the box 10, items at the top of the box 10 can be temporarily placed on the lid 30. The protrusion 311 can block the items and keep them in place, making it easier to take out and put in items and organize items inside the box 10.

[0090] In some examples, refer to Figure 8 As shown, Figure 8 This is a schematic diagram of the structure of a lid in a rigid trolley case provided in some embodiments of this application. The lid 30 may include a third side plate 320. The third side plate 320 may be connected to the end of the second top plate 310 away from the first top plate 130.

[0091] In some examples, with the cover 30 closed to the first opening 102, the third side plate 320 may be located at the end of the second top plate 310 away from the first top plate 130.

[0092] In some examples, the third side plate 320 and the second top plate 310 can be a single piece.

[0093] In some examples, refer to Figure 1 and Figure 2As shown, when the cover 30 is placed over the first opening 102, the third side plate 320 can extend toward the bottom plate 140 of the box 10.

[0094] In some examples, the distance by which the third side plate 320 extends toward the base plate 140 can be greater than the vertical opening size of the first opening 102 on the second side plate 12. Thus, the edge of the third side plate 320 can extend beyond the edge of the first opening 102 on the second side plate 12. This improves the sealing performance of the cover 30 over the first opening 102, effectively protecting the items within the accommodating space 101.

[0095] In some examples, refer to Figure 8 As shown, the cover 30 may include a fourth side plate 330. The fourth side plate 330 may be connected between the second top plate 310 and the third side plate 320. That is, one side of the fourth side plate 330 may be connected to the second top plate 310, and the other side of the fourth side plate 330 may be connected to the third side plate 320.

[0096] In some examples, refer to Figure 8 As shown, the cover 30 may include a fifth side plate 340. The fifth side plate 340 may be connected between the second top plate 310 and the third side plate 320. The fifth side plate 340 may be disposed opposite to the fourth side plate 330.

[0097] In some examples, the connection method between the fifth side plate 340 and the second top plate 310 and the third side plate 320 can be the same as, similar to or similar to that of the fourth side plate 330. For details, please refer to the detailed description of the fourth side plate 330 in the foregoing embodiments of this application. This application will not repeat the details in this embodiment.

[0098] In some examples, refer to Figure 8 As shown, the fourth side plate 330 and the fifth side plate 340 can be triangular or triangular-like.

[0099] In some examples, refer to Figure 4 and Figure 5 As shown, the fourth side panel 330 and the fifth side panel 340 can be rectangular. This increases the opening area of ​​the first opening 102, making it easier to put in and take out items.

[0100] In some examples, refer to Figure 6 and Figure 7 As shown, the fourth side panel 330 and the fifth side panel 340 can be trapezoidal. This increases the opening area of ​​the first opening 102, making it easier to put in and take out items.

[0101] In some examples, refer to Figure 8 and Figure 9 As shown, Figure 9 It is along Figure 8A cross-sectional view along the BB line. The protrusion 311 connects the fourth side plate 330 and the fifth side plate 340.

[0102] In some examples, multiple protrusions 311 may be intermittently provided between the fourth side plate 330 and the fifth side plate 340. The multiple protrusions 311 are arranged along the direction of the fourth side plate 330 and the fifth side plate 340 (e.g., Figure 8 Arranged in the direction shown by the x-axis.

[0103] In some examples, refer to Figure 9 As shown, the protrusion 311 can be a ridge or rib connecting the fourth side plate 330 and the fifth side plate 340. One end of the ridge or rib is connected to the fourth side plate 330, and the other end is connected to the fifth side plate 340. Thus, the protrusion 311 is a continuous integral part, which can block small items and facilitate the placement of small items on the cover 30.

[0104] In this embodiment, the protrusion 311 is connected between the fourth side plate 330 and the fifth side plate 340. Thus, referring to... Figure 3 As shown, when the lid 30 is flipped open, items taken from the receiving space 101 can be placed on the lid 30. The protrusion 311 acts as a barrier, improving the stability of the items and facilitating the removal of items below from the receiving space 101. Furthermore, placing items on the lid 30 and using the protrusion 311 to block them allows for easy display. This expands the usage scenarios of hard-sided rolling suitcases and increases their versatility.

[0105] In some examples, refer to Figure 3 , Figure 5 and Figure 7 As shown, the length of the protrusion 311 protruding from the second top plate 310 is less than the length of the third side plate 320.

[0106] In some examples of embodiments of this application, the length of the protrusion 311 extending beyond the second top plate 310 is set to be less than the length of the third side plate 320. This ensures that the space on the cover 30 for placing items has sufficient opening, facilitating the display or temporary storage of items on the cover 30. Furthermore, the protrusion 311 has sufficient protrusion length to provide stable support for items placed on the cover 30, improving the stability of items placed on the cover 30.

[0107] In some examples, refer to Figure 10 and Figure 11 As shown, Figure 10 This is another structural schematic diagram of the cover of a rigid trolley case provided in some embodiments of this application. Figure 11This is another structural schematic diagram of a rigid trolley case with the lid in an open state, provided in some embodiments of this application.

[0108] Reference Figure 10 and Figure 11 As shown, the lever 20 can be in a retracted state when the cover 30 is opened. That is to say, the cover 30 can be opened after the lever 20 is retracted.

[0109] In some examples, refer to Figure 2 As shown, along the arrangement direction of the first side plate 11 and the second side plate 12 (e.g.) Figure 2 (in the direction shown by the x-axis), the length of the second top plate 310 can be greater than the length of the first top plate 130.

[0110] In some examples, refer to Figure 2 As shown, the length of the second top plate 310 can be a third length L3. The length of the first top plate 130 can be a fourth length L4. The third length L3 can be greater than the fourth length L4. Thus, when the cover 30 is flipped over... Figure 3 , Figure 5 and Figure 7 In the state shown, since the fourth length L4 is less than the third length L3, the first opening 102 can be opened as close as possible to the first side plate 11, which can increase the opening area of ​​the first opening 102 and facilitate the taking and putting of items. In addition, after the cover 30 is flipped to the fully open state, the length of the third length L3 is longer, which can increase the space on the cover 30 to hold items, making it easier to place items on the cover 30 for temporary storage.

[0111] In some examples, along the arrangement direction of the first side panel 11 and the second side panel 12, the length of the second top panel 310 can be equal to the length of the first top panel 130. That is, the third length L3 can be equal to the fourth length L4. Then, the cover 30 is flipped over... Figure 3 In the state shown, since the third length L3 is equal to the fourth length L4, the third side plate 320 can just contact the pull rod 20, which can ensure that the cover 30 is flipped to the maximum angle.

[0112] In some examples, refer to Figure 1 As shown, the first top plate 130 may be provided with a handle 131. There may be a gap between the handle 131 and the first top plate 130, which facilitates lifting the rigid suitcase by lifting.

[0113] In some examples, a handle may be located in the middle of the first top plate 130.

[0114] In some examples of embodiments of this application, a handle 131 is provided on the first top plate 130. Thus, when the pull rod 20 is retracted, the rigid suitcase can be moved via the handle 131. This expands the applicability of the rigid suitcase and facilitates its movement.

[0115] In some examples, a lock (not shown in the figure) may be provided on the third side panel 320, and the cover 30 can be locked to the box 10 by the lock.

[0116] In some examples, the lock may include any of the following: a combination lock, a zipper, or a latch lock.

[0117] In some examples of embodiments of this application, the handle 131 is disposed in the middle of the first top plate 130. Thus, the force exerted by the handle 131 on the first top plate 130 is mainly concentrated on the first top plate 130. This increases the weight of items that can be placed inside the rigid suitcase, avoiding deformation or damage to the lid 30 caused by the force exerted by the handle 131 on the lid 30 due to the weight of the items placed inside. This extends the service life of the rigid suitcase and increases the weight of the items placed inside. Simultaneously, it avoids the risk of deformation or damage to the latch, zipper, or lid due to pulling force when the handle is in the position of the liftable lid.

[0118] In some examples, rigid rolling cases may include coverings (not shown in the figures).

[0119] In some examples, the cover may cover the edge of the first opening 102.

[0120] In some examples, the cover may cover the edge of the cover 30.

[0121] In some examples, the covering may include a metal component. For example, the covering may be made of aluminum alloy, stainless steel, etc. The covering may be riveted to the edge of the first opening 102 and the edge of the cover 30.

[0122] In some examples, the covering may include leather.

[0123] In some examples, the covering may include a rigid plastic part.

[0124] Figure 12 This is another structural schematic diagram of a rigid trolley case with the lid in an open state, provided in some embodiments of this application. Figure 13 It is along Figure 12 A cross-sectional view of the CC line.

[0125] In some examples, the housing 10 may have a partition 113. The partition 113 may be made of a rigid material. For example, the partition 113 may include a rigid plastic sheet or a corrugated sheet, etc.

[0126] In some examples, the partition 113 may be positioned in the middle of the accommodating space 101. Figure 13 The direction shown is used as an example, the partition can accommodate the space 101 from the vertical direction (e.g., Figure 13 The space is divided into two parts (in the direction indicated by the z-axis). In this way, the items in the upper and lower parts of the accommodating space 101 will not affect each other. The items in the upper part are separated from the items in the lower part by the partition, so they will not be squeezed and can be protected from damage.

[0127] In some examples, one end of the partition 113 can be rotatably connected to the inner wall of the housing 10. The partition 113 can be connected to the inner wall of the housing 10 via a flexible connector.

[0128] In some examples, the partition 113 can be connected to the inner wall of the housing 10 by means of woven straps or elastic ropes. This makes it easy for the partition 113 to flip and rotate within the receiving space 101.

[0129] In some examples, the other end of the partition 113 can be detachably connected to the inner wall of the housing 10. For example, the other end of the partition 113 can be detachably connected to the inner wall of the housing 10 via a snap-fit ​​mechanism.

[0130] In some examples, the other end of the partition 113 can be detachably connected to the inner wall of the box 10 by means of plugging or magnetic attraction. In this way, after the items above the partition 113 are removed, the other end of the partition 113 can be easily detached, and the partition 113 can be flipped over to remove the items from below. This improves the convenience of taking and placing items.

[0131] In some examples, refer to Figure 2 and Figure 14 As shown, Figure 14 This is a schematic diagram of the structure of a rigid trolley case provided in some embodiments of this application. The first side panel 11 may be provided with a mounting cavity 111. The trolley rod 20 can be inserted into the mounting cavity 111.

[0132] In some examples, refer to Figure 14 As shown, the mounting cavity 111 may have a second opening 112. The second opening 112 may be located on the first top plate 130. The mounting cavity 111 may be located along the height direction of the housing 10 (e.g., along the height direction of the housing 10). Figure 8 (In the direction shown by the z-axis) it extends toward the bottom plate 140 of the housing 10.

[0133] In some examples, the pull rod 20 can be slidably connected to the mounting cavity 111.

[0134] Figure 15This is a schematic diagram of the structure of a rigid trolley case provided in some embodiments of this application, showing the cooperation between the trolley rod and the case body.

[0135] In some examples, refer to Figure 15 As shown, the pull rod 20 can be an external pull rod 20. That is, the mounting cavity 111 can be located on the outside of the first side plate 11. After the pull rod 20 is installed in the mounting cavity 111, the pull rod 20 can protrude from the outside of the first side plate 11.

[0136] It is understood that in some embodiments of this application, the pull rod 20 protruding from the outer side of the first side plate 11 is only shown as a specific example and is not intended to limit the specific arrangement of the pull rod 20. In other embodiments, a groove (not shown in the figure) may be provided on the outer side of the first side plate 11, and the pull rod 20 may be disposed in the groove. That is, the side of the pull rod 20 facing away from the case 10 may be exposed outside the case 10, but the side of the pull rod 20 facing away from the case 10 may be flush with the outer surface of the first side plate 11. In this way, the flatness of the outer side of the rigid trolley case can be ensured, thus enhancing the protection of the pull rod 20.

[0137] In some examples, the pull rod 20 may be a built-in pull rod 20. After the pull rod 20 is installed in the mounting cavity 111, the pull rod 20 may be located inside the first side plate 11.

[0138] In some examples, refer to Figure 16 As shown, Figure 16 This is a schematic diagram of the structure of the pull rod in a rigid trolley case provided in some embodiments of this application. The pull rod 20 can be a flat pull rod 20. In this way, the pull rod 20 can be pulled along the width direction of the case body 10 (e.g., Figure 14 The dimension of the pull rod 20 (in the direction shown by the x-axis) is set to be larger, thereby reducing the thickness of the pull rod 20 along the rigid pull case (e.g., in the direction shown by the x-axis). Figure 14 The dimension (in the direction shown by the y-axis). In this way, the size of the mounting cavity 111 encroaching on the receiving space 101 can be reduced, thereby increasing the effective volume of the receiving space 101.

[0139] In some examples, refer to Figure 16 As shown, the pull rod 20 may include a handle 210 and a rod body 220. The rod body 220 may be inserted into the mounting cavity 111, and the handle 210 may be connected to the end of the rod body 220. The handle 210 may be located outside the mounting cavity 111.

[0140] In some examples, the rod 220 can be a flat rod.

[0141] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0142] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
