Description

[Technical Field]

[0001] The present invention relates to the technical field of suitcases, and more particularly to suitcases that can be used by passengers. [Background technology]

[0002] Suitcases are widely used in people's daily outings and are used to store the items they need when they go out. Since people often take their children with them when they go out, some children ride in the suitcase and move around using the rolling casters at the bottom of the suitcase, as they need to play or adults think it is easy to take children with them, but doing so makes the suitcase more likely to be damaged.

[0003] Therefore, some suitcases have an integrated frame for children to sit on to make it easier for children to ride, but how to unfold and secure the frame is an issue that needs to be resolved quickly.The connection structure between the conventional frame and suitcase is complex, and the frame is not stable enough after unfolding. Summary of the Invention [Problem to be solved by the invention]

[0009] In one embodiment, the base body includes a first housing and a second housing provided separately, the second housing is connected to the first housing and cooperates to form the guide groove, the second housing is recessed toward the first housing to form an anti-misoperation groove, and the operation port is opened at the bottom of the anti-misoperation groove.

[0010] In one embodiment, a reinforcing rib is provided in the guide groove, and the reinforcing rib is connected to at least one side of a groove wall that forms the guide groove.

[0011] In one embodiment, the locking member further includes a position limiting portion connected to the insertion portion and located at an end of the insertion portion away from the lock base, and the position limiting portion abuts against the reinforcing rib as the insertion portion is inserted into the locking groove.

[0012] In one embodiment, the frame further includes a fixed base, a movable base, and an elastic member, the fixed base is fixedly connected to the main lever, the movable base is slidably connected to the main lever, the elastic member is located between the fixed base and the movable base, one end of the elastic member abuts the fixed base and the other end of the elastic member abuts the movable base, the movable base is movable along the axial direction of the main lever, and when the main lever moves toward the case body, the movable base cooperates with the case body to lock.

[0013] In one embodiment, a protruding block is provided on the side of the movable base facing the rotating base, and a groove is opened on the side of the rotating base facing the movable base, so that the rotating base can be rotated toward the movable base and the protruding block can be engaged and connected to the groove.

[0014] In one embodiment, a pivot shaft is provided within the lock base, the pivot shaft is coaxial with the lock base, the pivot shaft passes through at least one side of the lock base and is connected to the pivot base.

[0015] In one embodiment, the base body is arranged to cover both sides of the lock base in the axial direction, and both ends of the rotation axis pass through both side surfaces of the lock base and are respectively connected to the base body. [Effects of the Invention]

[0016]

[0003] Compared with the prior art, this invention has a locking base and a pivoting base, where the locking base is fixedly connected to the main lever and the pivoting base is pivotally connected to the locking base, allowing the pivoting base to pivot relative to the main lever, and the support lever is connected to the pivoting base, allowing the support lever to pivot relative to the main lever. That is, when the pivoting base rotates relative to the locking base, the support lever also rotates synchronously relative to the main lever, thereby realizing the frame deployment. The locking base has at least two locking grooves (2) formed along the circumferential direction, i.e., the two locking grooves (2) are arranged at an angle. When a locking member is inserted into one of the locking grooves, the base body can be fixed and limited in position relative to the locking base, thereby realizing a constant angle between the support lever and the main lever and maintaining the frame in a stable deployed state. When a locking member is inserted into the other locking groove, the support lever and the main lever can be supported at a different angle, allowing the frame to be deployed at a different angle.

[0023] Conventional suitcases usually have a case body and a frame integrated together to make it easier for children to ride in. However, the connection structure between the case body and the frame is complicated, and when the frame needs to be unfolded to allow a child to ride in, the operation is complicated and the frame is not stable enough after unfolding.

[0024] In contrast, referring to Figure 5, the present invention includes a case body 10 and a frame 20, the frame 20 is connected to the case body 10, and the frame 20 can be unfolded relative to the case body 10. When the frame 20 is unfolded, a seat-on suitcase 100 is provided in which a child can ride on the frame 20.

[0025] 1 to 4, the frame 20 includes a main lever 21, a lock base 22, a rotating base 23, and a support lever 24, the lock base 22 is fixedly connected to the main lever 21, the rotating base 23 is rotatably connected to the lock base 22, the support lever 24 is connected to the rotating base 23, and the rotating base 23 is rotatable relative to the lock base 22 so as to rotate the support lever 24 relative to the main lever 21, the rotating base 23 includes a base body 231 and a locking member 232, the locking member 232 is movably connected to the base body 231 and can move toward or away from the lock base 22, the lock base 22 has at least two locking grooves 221 opened along the circumferential direction, and the locking member 232 can be inserted and fitted into the locking grooves 221. In this way, since the lock base 22 is fixedly connected to the main lever 21 and the rotating base 23 is rotatably connected to the lock base 22, the rotating base 23 is rotatable relative to the main lever 21, and since the support lever 24 is connected to the rotating base 23, the support lever 24 is rotatable relative to the main lever 21. In other words, while the rotating base 23 is rotating relative to the lock base 22, the support lever 24 also rotates synchronously relative to the main lever 21, thereby enabling the frame 20 to be unfolded. At least two locking grooves 221 are formed in the locking base 22 along the circumferential direction, i.e., the two locking grooves 221 are arranged at an angle. When the locking member 232 is inserted into one of the locking grooves 221, the base body 231 can be fixed to the locking base 22 and its position can be restricted. This makes it possible to maintain a constant angle between the support lever 24 and the main lever 21 and to maintain the frame 20 in a stably deployed state. When the locking member 232 is inserted into the other locking groove 221, the support lever 24 and the main lever 21 can be supported at a different angle, thereby enabling the frame 20 to be deployed at a different angle.

[0026] In this embodiment, the lock base 22 has two locking grooves 221. In other embodiments, the number of locking grooves 221 is not limited to two, and may be three, four, or five. Each locking groove 221 is arranged at an angle to the adjacent locking groove 221. When five locking grooves 221 are provided, the lock base 22 can be stably deployed at five angles with the rotating base 23.

[0027] A guide groove 2311 is formed in the base body 231, and the locking member 232 is provided in the guide groove 2311 and is movable along the extending direction of the guide groove 2311. In this way, the locking member 232 is connected to the guide groove 2311 and is less likely to fall off, and the movement of the locking member 232 can be guided by the groove wall of the guide groove 2311, thereby making it possible to insert and remove the locking member 232 into and from the locking groove 221 more stably.

[0028] Preferably, the guide groove 2311 is provided inside the base body 231 so that the locking member 232 does not fall off from the base body 231. In other embodiments, the guide groove 2311 may be provided on the outside of the base body 231, as long as it can provide the effect of guiding the direction of the locking member 232.

[0029] Furthermore, the locking member 232 includes an insertion portion 2321 and an operating portion 2322, the insertion portion 2321 is connected to the operating portion 2322, the insertion portion 2321 abuts against and fits into the groove wall of the guide groove 2311, and moves along the groove opening direction of the guide groove 2311, an operating port 2312 is opened on one side of the base body 231, and the operating port 2312 is arranged at an angle to the movement direction of the locking member 232, at least a part of the operating portion 2322 extends from the operating port 2312, and the operating portion 2322 can abut against the edge of the operating port 2312 as the insertion portion 2321 moves.

[0030] In this way, the operation opening 2312 is used for extending the operation unit 2322 from the base main body 231, thereby allowing a user to directly bias the operation unit 2322 externally, and since the operation unit 2322 is connected to the insertion unit 2321, the operation unit 2322 can move and drive the insertion unit 2321, that is, the user can directly operate the operation unit 2322 externally to connect and lock or unlock the rotating base 23 and the lock base 22. In addition, the edge of the operation opening 2312 can abut against the operation unit 2322, thereby restricting the movement of the operation unit 2322 and making it possible to notify that the operation unit 2322 has moved to a predetermined position.

[0031] As can be appreciated, in other embodiments, other methods can be used to achieve the movement of the locking member 232. For example, one end of the guide groove 2311 is provided with a motor that moves together with the locking member 232, and a lead screw is connected to the motor, the lead screw is inserted into the locking member 232, and when the motor rotates to rotate the lead screw, the lead screw can move the locking member 232.

[0032] Furthermore, the base main body 231 includes a first housing 2313 and a second housing 2314 which are provided separately, the second housing 2314 is connected to the first housing 2313 and cooperates to form a guide groove 2311, the second housing 2314 is recessed toward the first housing 2313 to form an erroneous operation prevention groove 2315, and the operation opening 2312 is opened at the bottom of the erroneous operation prevention groove 2315. In this way, the base main body 231 is formed by combining the first housing 2313 and the second housing 2314, and the processing process is simple and low cost. In addition, since the anti-misoperation groove 2315 is recessed toward the first housing 2313, the position of the operation opening 2312 is also close to the first housing 2313 or away from the surface of the second housing 2314, and when the operation part 2322 extends from the operation opening 2312, it can be positioned within the anti-misoperation groove 2315. This prevents a safety accident from occurring when the seat-compatible suitcase 100 is in use, in which the operation part 2322 collides with an external element, releasing the lock between the lock base 22 and the rotating base 23, causing the frame 20 to suddenly contract and causing a child to fall.

[0033] A reinforcing rib 2316 is provided in the guide groove 2311, and the reinforcing rib 2316 is connected to at least one side of the groove wall that forms the guide groove 2311. The reinforcing rib 2316 can increase the structural strength of the base body 231.

[0034] The locking member 232 further includes a position limiting portion 2323, which is connected to the insertion portion 2321 and located at an end of the insertion portion 2321 farther from the lock base 22, and as the insertion portion 2321 is inserted into the locking groove 221, the position limiting portion 2323 comes into contact with the reinforcing rib 2316. In this way, the further contact between the position limiting portion 2323 and the reinforcing rib 2316 makes the movement of the locking member 232 more stable and prevents excessive movement of the locking member 232.

[0035] The frame 20 further includes a fixed base 25, a movable base 26, and an elastic member 27, the fixed base 25 is fixedly connected to the main lever 21, the movable base 26 is slidably connected to the main lever 21, the elastic member 27 is located between the fixed base 25 and the movable base 26, one end of the elastic member 27 abuts the fixed base 25, and the other end of the elastic member 27 abuts the movable base 26, the movable base 26 is movable along the axial direction of the main lever 21, and when the main lever 21 moves toward the case body 10, the movable base 26 cooperates with the case body 10 to lock.

[0036] The movable base 26 is connected to the main lever 21, and the movable base 26 can be connected to and locked with the case body 10, so that the main lever 21 can be fixed to the case body 10 via the movable base 26, thereby fixing and connecting the frame 20 and the case body 10. When the frame 20 moves toward the case body 10, the movable base 26 can abut against the first lock assembly, and because the movable base 26 is slidably connected to the main lever 21, the movable base 26 can move along the axial direction of the main lever 21 in response to the abutting force with the case body 10, thereby preventing the case body 10 from moving. Furthermore, one end of the elastic member 27 abuts against the fixed base 25, whose position is relatively fixed, and the other end of the elastic member 27 abuts against the movable base 26, so that the elastic member 27 can move the movable base 26 in a direction away from the fixed base 25, thereby returning the movable base 26 to engage and connect with the case body 10.

[0037] A protruding block 261 is provided on the side of movable base 26 facing pivot base 23, and a groove 233 is formed on the side of pivot base 23 facing movable base 26, allowing pivot base 23 to pivot toward movable base 26 and allowing protruding block 261 to be engaged and connected to groove 233. In this way, when pivot base 23 has not pivoted away from case body 10, groove 233 remains engaged and connected to protruding block 261, ensuring a stable position of movable base 26 and preventing main lever 21 from coming off case body 10 and causing a safety accident when movable base 26 is accidentally hit.

[0038] A rotation shaft is provided within the lock base 22, and the rotation shaft is provided coaxially with the lock base 22. The rotation shaft penetrates at least one side of the lock base 22 and is connected to the rotation base 23. The lock base 22 is rotatably connected to the rotation base 23 via the rotation shaft, and the structure is simple and the cost is low.

[0039] Furthermore, the base body 231 is provided so as to cover both sides of the lock base 22 in the axial direction, and both ends of the rotating shaft penetrate both side surfaces of the lock base 22 and are respectively connected to the base body 231. In this way, both ends of the rotating shaft and the base body 231 have connection points that receive force, making it possible to further stabilize the relative rotation between the rotating base 23 and the lock base 22.

[0040] Compared with the prior art, in this invention, a lock base 22 and a pivot base 23 are installed, the lock base 22 is fixedly connected to the main lever 21, and the pivot base 23 is pivotally connected to the lock base 22, so that the pivot base 23 can pivot relative to the main lever 21. In addition, the support lever 24 is connected to the pivot base 23, so that the support lever 24 can pivot relative to the main lever 21. In other words, while the pivot base 23 is pivoting relative to the lock base 22, the support lever 24 also pivots synchronously relative to the main lever 21, thereby realizing the deployment of the frame 20. At least two locking grooves 221 are formed in the locking base 22 along the circumferential direction, i.e., the two locking grooves 221 are arranged at an angle. When the locking member 232 is inserted into one of the locking grooves 221, the base body 231 can be fixed to the locking base 22 and its position can be restricted. This makes it possible to maintain a constant angle between the support lever 24 and the main lever 21 and to maintain the frame 20 in a stably deployed state. When the locking member 232 is inserted into the other locking groove 221, the support lever 24 and the main lever 21 can be supported at a different angle, thereby enabling the frame 20 to be deployed at a different angle.

[0041] The technical features of the above-described embodiments can be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described, but any combination of these technical features should be considered to be within the scope described in this specification unless there is a contradiction.

[0042] The above-mentioned examples only represent some embodiments of the present invention, and although the description is more specific and detailed, it should not be understood as a limitation on the scope of the claims of the present invention. It should be noted here that those skilled in the art may make some modifications and improvements without departing from the concept of the present invention, and all of these fall within the scope of protection of the present invention. Therefore, the scope of the claims of the present invention should be governed by the appended claims. [Explanation of symbols]
