Description

Technical Field

[0001] This utility model belongs to the technical field of luggage accessories, specifically relating to a highly stable folding seat for children's luggage. Background Technology

[0002] Children's suitcases refer to ordinary suitcases with child seats installed, allowing children to sit on them. These suitcases are widely used in current technology and can accommodate children.

[0003] Existing child seat designs typically include a backrest that is foldable and mounted on the suitcase to minimize storage space. However, the connection between the backrest and the suitcase in these designs is flawed, resulting in weak bonding and potential safety hazards. Utility Model Content

[0004] This invention provides a highly stable folding seat for children's suitcases, aiming to solve the problem of low connection strength between the backrest and the suitcase in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A highly stable folding seat for children's suitcases includes a seat body, a backrest provided on the seat body, and the backrest being rotatably connected to the seat body via a connecting assembly;

[0007] A locking component is also provided between the seat and the backrest to lock the backrest onto the seat;

[0008] The backrest has a folded state and an unfolded state. When the backrest is in the unfolded state, the locking component releases the backrest. When the backrest is in the locked state, the locking component locks the backrest. Both the locking component and the connecting component bear the force acting on the backrest.

[0009] A further improved solution: The connecting component includes a pivot, and the backrest is rotatably connected to the seat body via the pivot.

[0010] Based on the above technical solution: the pivot, as the core component for rotational connection, ensures that the backrest can smoothly switch between folded and unfolded states. This flexibility makes children's suitcases convenient to store and use. The pivot is usually made of wear-resistant and lubricating materials, reducing friction and wear on the backrest during rotation and extending its service life. The pivot not only handles rotational connection but also enhances the connection strength between the backrest and the seat through its structural design. This design allows the backrest to remain stable when bearing the weight of a child or external forces, preventing it from wobbling or falling off. As a connection point, the pivot effectively distributes various forces acting on the backrest, reducing the pressure on individual components and improving the overall structural stability and durability.

[0011] A further improved solution: The locking assembly includes a locking pin disposed on the backrest, and the seat body is provided with a locking hole that cooperates with the locking pin. When the locking assembly releases the backrest, the locking pin disengages from the locking hole. When the locking assembly locks the backrest, the locking pin cooperates with the locking hole.

[0012] Based on the above technical solution: the tight fit between the locking pin and the locking hole ensures that the backrest will not wobble or fall off in the locked state, providing a stable riding environment for children. Through the locking action of the locking assembly, the connection strength between the backrest and the seat is significantly improved, effectively preventing connection failure due to external forces. The reliable design of the locking assembly effectively prevents the backrest from accidentally folding or unfolding during use, thus avoiding potential safety hazards. The stable locking effect gives parents greater peace of mind when letting children ride on luggage, improving overall safety. The design of the locking assembly makes locking and unlocking operations very simple; users can easily fix and release the backrest with a simple operation. By adjusting the state of the locking assembly, users can easily adapt to different usage scenarios and needs, such as storage, carrying, or children riding.

[0013] A further improvement: The locking assembly further includes a handle for operating the locking pin to engage or disengage the locking pin from the locking hole.

[0014] Based on the above technical solution: the handle design allows users to directly control the engagement or disengagement of the locking pin and locking hole manually, eliminating the need for complicated steps or tools and greatly simplifying the operation process. The handle is typically ergonomically designed, allowing users to easily apply force during operation, reducing physical exertion and improving comfort. Through handle operation, users can more precisely control the position of the locking pin, ensuring accurate alignment with the locking hole, thus achieving a reliable locking effect. Handle operation provides immediate feedback on the status of the locking components, allowing users to confirm successful locking through touch or visual observation, improving operational accuracy.

[0015] A further improvement: The backrest is also provided with a through hole, through which the handle extends out of the backrest.

[0016] Based on the above technical solution: the handle extends from the backrest through a through-hole, allowing users to directly access and operate it without opening or disassembling any parts, greatly improving ease of operation. Users can intuitively understand the working status of the locking component by observing the position and status of the handle, thus enabling accurate operation. The through-hole design allows the handle to naturally conform to the backrest surface or be hidden within the through-hole when the backrest is folded or unfolded, without occupying extra space and optimizing the overall space utilization of the suitcase. The concealed design of the handle avoids interference with other items during suitcase storage or carrying, improving the smoothness of use. The through-hole design limits the range of motion of the handle, preventing accidental unlocking of the locking component due to accidental touch, enhancing safety. The tight fit between the through-hole and the handle ensures the stability of the locking component under force, preventing safety hazards caused by structural loosening.

[0017] A further improved solution: There are two locking components, which are respectively disposed on both sides of the backrest.

[0018] Based on the above technical solution, two locking components act on both sides of the backrest, providing double locking protection. Even if one locking component malfunctions or is subjected to excessive force, the other locking component can still maintain the stability of the backrest, greatly reducing safety hazards. The distribution of the two locking components ensures that the backrest is evenly stressed when locked, avoiding structural deformation or damage caused by uneven stress and extending its service life. Redundancy design is a common method to improve system reliability. By setting two locking components, even if one malfunctions, the other can still function normally, ensuring the reliability of the backrest's locking. For parents, the design of the double locking components undoubtedly increases their confidence in the safety of children's suitcases, making them feel more at ease during travel. The design of two locking components allows children's suitcases to adapt to more diverse usage scenarios. For example, when walking on uneven surfaces, the double locking components can provide better stability and support, ensuring the safety of children.

[0019] A further improved solution: The seat body is provided with a positioning groove, the backrest includes a body and a positioning part, the positioning part is located in the positioning groove, when the backrest is in the locked state, the positioning part contacts the bottom wall of the positioning groove, and the locking component and the connecting component are both provided on the positioning part.

[0020] Based on the above technical solution: the cooperation between the positioning part and the positioning groove achieves precise positioning of the backrest, ensuring that the backrest can be stably maintained in the predetermined position in the locked state, and will not easily shake or shift due to external forces. When the backrest is in the locked state, the positioning part contacts the bottom wall of the positioning groove, increasing the contact area and thus improving the connection strength and stability between the backrest and the seat. Both the locking component and the connecting component are located on the positioning part. This design allows the backrest to distribute the force to the contact surface between the positioning part and the positioning groove when under stress, avoiding structural damage or locking failure caused by single-point stress. The tight cooperation between the positioning part and the positioning groove provides additional support for the locking component, enhancing the locking force and making the backrest more secure and reliable in the locked state.

[0021] A further improved solution: One end of the positioning groove is provided with a positioning wall to improve the stability of the backrest relative to the body. When the backrest is in the locked state, a part of the body contacts the positioning wall.

[0022] Based on the above technical solution: the positioning wall provides additional support points for the backrest, and together with the locking and connecting components, enhances the backrest's stability in the locked state. The contact between the positioning wall and the main body increases the difficulty of unlocking the locking component, thereby improving locking reliability and preventing unlocking due to accidental contact or vibration. The tight contact between the positioning wall and the main body reduces noise caused by shaking or movement, improving the user experience. The stable locking effect and additional support give users greater peace of mind when using children's suitcases, enhancing their confidence in the product's safety.

[0023] A further improvement: The backrest is also provided with mounting holes for installing seat belts, and the mounting holes penetrate the backrest.

[0024] Based on the above technical solution, the design of the mounting holes allows the seat belt to be securely fixed to the backrest, providing reliable fixation and protection for the passenger. Even in situations involving bumps, the seat belt can effectively prevent injury to the passenger due to inertia. By rationally arranging the position and number of mounting holes, it can be ensured that the seat belt is neither too tight causing discomfort nor too loose to lose its protective function. This design improves passenger comfort while also enhancing safety.

[0025] A further improved solution: the seat body includes a seat plate, and the backrest is disposed on the seat plate;

[0026] Alternatively, the seat body includes a seat plate and a cushion, the cushion being detachably mounted on the seat plate and the backrest being mounted on the cushion.

[0027] Based on the above technical solution: As the seat component of a child's suitcase, its primary function is to provide a stable support surface, allowing children to sit safely and comfortably. Whether the design includes only a seat board or a design that includes both a seat board and a removable cushion, this basic functional requirement can be met. The removable cushion design makes the seat more flexible and versatile. In different usage scenarios, parents can choose whether to install the cushion as needed, thereby adjusting the seat's comfort. This design also allows parents to easily adjust the seat configuration during travel as their child grows and changes, meeting the needs of different stages.

[0028] The beneficial effects of this utility model are as follows:

[0029] This invention utilizes a locking mechanism that allows the backrest to be released when unfolded and securely locked when needed, ensuring stability during use. This design effectively prevents safety risks caused by backrest wobbling or detachment, allowing the backrest to withstand greater forces. Even if children lean against the backrest, it will not detach or be damaged, thus improving the safety performance of the suitcase.

[0030] The connecting assembly not only connects the backrest to the seat body, but also, together with the locking assembly, bears the various forces acting on the backrest. This design enhances the connection strength between the backrest and the suitcase, further improving the overall structural stability.

[0031] The backrest is foldable and integrated into the suitcase, allowing it to take up less space when packed away, making it easier to carry and store. The locking mechanism makes locking and unlocking the backrest simple and quick, and users can easily adjust the backrest's position as needed. Attached Figure Description
