[0028] like Figures 1 to 10 As shown, the first embodiment of the present invention provides a flip-type seat, comprising: The seat cushion 100 has mounting seats 102 at opposite ends and both sides of the seat cushion 100, and mounting slots 104 are formed on the mounting seats 102; A backrest 106 , on which a support shaft 108 is disposed, and the support shaft 108 is detachably mounted in the mounting groove 104 ; The locking structure is used to lock the relative position of the support shaft 108 and the mounting groove 104 and to lock the relative angle between the seat cushion 100 and the backrest 106 when the support shaft 108 is inserted into the mounting groove 104 .

[0029] According to the first aspect of the present invention, the flap-type seat provided by the embodiment is extremely easy to install and disassemble by arranging the mounting seat 102 and the mounting groove 104 on the seat cushion 100 and arranging the detachable support shaft 108 on the backrest 106. The user can quickly assemble or disassemble the seat as needed, and adjust the installation direction of the backrest 106, thereby improving the convenience of use. At the same time, the flap-type seat can also save disassembly and assembly space, and the installation direction of the backrest 106 can be adjusted without rotation. The design of the locking structure ensures the stable position of the support shaft 108 in the mounting groove 104, effectively preventing the loosening or displacement that may occur during use. The locking structure can also fix the relative angle between the seat cushion 100 and the backrest 106, thereby enhancing the overall stability of the seat. Due to the detachability of the support shaft 108, the user can adjust the angle of the backrest 106 according to personal preference or actual needs to obtain the best sitting posture and comfort. This design meets the diverse needs of different users for seat angles. The detachable design of the support shaft 108 and the mounting groove 104 makes it easy to maintain and replace parts of the seat. When a part is damaged or needs to be replaced, the user can easily remove and replace it with a new part, thereby extending the service life of the seat. The design of this flip-type seat is flexible and can adapt to different usage scenarios and needs. Whether it is a road vehicle or a railway vehicle, the appropriate seat configuration can be selected according to actual needs. The flip-type seat has a simple and effective structural design, achieving a variety of technical effects such as easy installation, high stability, adjustable angle, easy maintenance and replacement, and strong adaptability, providing users with a more comfortable and convenient seat experience.

[0030] Please continue to see Figures 1 to 10 The main parts of the flip-type chair include a seat cushion 100, a backrest 106 and a locking structure. The seat cushion 100 is provided with mounting seats 102, which are located at opposite ends and both sides of the seat cushion 100, and each mounting seat 102 has a mounting slot 104. The backrest 106 is provided with a support shaft 108, which can be detachably installed in the mounting slot 104 of the seat cushion 100. When the support shaft 108 is inserted into the mounting slot 104, the locking structure will work to ensure that the relative position of the support shaft 108 and the mounting slot 104 is fixed, and at the same time, the relative angle between the seat cushion 100 and the backrest 106 is locked.

[0031] Specifically, the design of the seat cushion 100 takes into account the convenience and stability of installation. By arranging mounting seats 102 at opposite ends and both sides of the seat cushion 100, and opening mounting slots 104 on these mounting seats 102, a stable support and a convenient insertion position are provided for the support shaft 108 of the backrest 106. It can be understood that the two ends of the seat cushion 100 mentioned here refer to the front and rear ends of the seat cushion 100, and the two sides of the seat cushion 100 refer to the left and right sides of the seat cushion 100.

[0032] The design of the backrest 106 focuses on comfort and durability. The arrangement of the support shaft 108 allows the backrest 106 to be flexibly connected to the seat cushion 100, and the material and structural design of the support shaft 108 also ensure its sufficient strength and durability.

[0033] The locking structure is an important innovation of the present flip-type chair. After the support shaft 108 is inserted into the mounting groove 104, it can effectively lock the relative position of the support shaft 108 and the mounting groove 104 to prevent them from loosening or shifting during use. At the same time, the locking structure can also lock the relative angle between the seat cushion 100 and the backrest 106 to ensure the overall stability and comfort of the chair.

[0034] The design of this flip-plate seat not only facilitates the user to adjust the angle of the backrest 106 as needed, but also makes the assembly and disassembly of the seat easier. At the same time, the detachable design of the support shaft 108 and the mounting slot 104 also makes it easier to maintain and replace parts of the seat. When the user needs to adjust the direction of the backrest 106, he only needs to remove the backrest 106 from the mounting seat 102 and then replace it with the mounting seat 102 at the other end to adjust the direction of the seat.

[0035] The flip-up seat achieves a perfect combination of convenience, stability and comfort through reasonable structural design, meeting the user's various demands for seats.

[0036] According to one embodiment of the present invention, the mounting groove 104 includes an entry section and a rotation section that are connected to each other, the entry section is connected to the edge of the mounting seat 102, and a fixing groove 110 is formed on the groove side wall of the rotation section; The locking structure includes a locking plate 120 and a friction gasket 116. The friction gasket 116 is sleeved on the support shaft 108. A fixing block 112 corresponding to the fixing groove 110 is provided on the friction gasket 116. When the support shaft 108 is inserted into the mounting groove 104, the fixing block 112 is inserted into the fixing groove 110 to install the mounting seat in the mounting groove 104.

[0037] In the embodiment of the present invention, the mounting groove 104 is composed of an entry section and a rotation section that are interconnected. The entry section is designed to be simple and connected to the edge of the mounting seat 102, providing a smooth passage for the insertion of the support shaft 108. The user can easily align the support shaft 108 with the entry section and insert it smoothly without complicated operations or tools.

[0038] The side wall of the groove of the rotating section is provided with a fixing groove 110. The position and size of the fixing groove 110 are precisely calculated to ensure a perfect match with the fixing block 112 in the locking structure. When the support shaft 108 is inserted into the rotating section, the fixing block 112 can be accurately aligned and inserted into the fixing groove 110, thereby achieving a firm connection between the support shaft 108 and the mounting groove 104.

[0039] The locking structure, as a key component to achieve seat stability, includes a locking plate 120. The locking plate 120 is designed to be sturdy and durable, and can withstand various force impacts in daily use. A fixing block 112 corresponding to the fixing groove 110 is provided on the locking plate 120. The fixing block 112 is made of wear-resistant and high-strength material and can maintain a stable plug-in state for a long time.

[0040] When the support shaft 108 is inserted into the mounting groove 104, the user can align the locking plate 120 with the mounting groove 104 through simple operations, so that the fixing block 112 can be smoothly inserted into the fixing groove 110. In this process, the tight combination between the fixing block 112 and the fixing groove 110 firmly locks the support shaft 108 in the mounting groove 104 to prevent it from shaking or falling off.

[0041] This design not only simplifies the installation process of the seat, but also improves the stability and safety of the seat. Users can quickly complete the installation and removal of the seat as needed, while ensuring that the seat always remains stable during use.

[0042] In addition, the user can also conveniently adjust the angle of the backrest 106 to meet the needs of different sitting postures by adjusting the positions of the locking plate 120, the friction pad 116 and the fixing block 112. This flexibility makes the flip-type chair more adaptable to different occasions and user needs.

[0043] Therefore, this embodiment achieves the characteristics of easy installation, high stability and angle adjustment of the flip-type seat by optimizing the design of the installation groove 104 and the locking structure, providing users with a more convenient and comfortable seat use experience.

[0044] According to an embodiment of the present invention, there are a plurality of fixing grooves 110 , and the plurality of fixing grooves 110 are arranged at intervals along the circumference of the rotating section.

[0045] The provision of multiple fixing slots 110 means that the fixing block 112 in the locking structure has more selection positions to match the fixing slots 110. Such a design allows the user to select the most suitable position of the fixing slot 110 for installation according to actual needs and preferences when installing the seat 102. This flexibility not only makes the installation process smoother, but also can meet the personalized needs of different users.

[0046] At the same time, the fixing grooves 110 are arranged at intervals along the circumference of the rotating section, which also increases the connection stability between the support shaft 108 and the mounting groove 104. When the fixing block 112 is inserted into the fixing groove 110, the position of the support shaft 108 in the mounting groove 104 is effectively fixed and restricted, reducing the risk of loosening or displacement caused by external force or vibration. This design makes the seat more stable and reliable during use, providing users with a more comfortable and safe seat experience.

[0047] In addition, the design of multiple fixing slots 110 also takes into account the convenience of seat maintenance and replacement of parts. When a fixing slot 110 or a fixing block 112 is damaged, the user can select other undamaged fixing slots 110 for installation without replacing the entire installation slot 104 or the locking structure. This not only reduces maintenance costs, but also extends the service life of the seat.

[0048] In summary, the embodiment of the present invention optimizes the design of the installation slots 104 of the flip-type seat by increasing the number of the fixing slots 110 and arranging them at intervals along the circumference of the rotating section. This design not only improves the stability and safety of the seat, but also increases the flexibility and convenience of installation, providing users with a more high-quality and comfortable seat experience.

[0049] like Figure 8 and Fig. 9 As shown, according to one embodiment of the present invention, a threaded section 128, a special-shaped section 130 and an optical axis section 132 are sequentially provided at one end of the support shaft 108 away from the backrest 106, and a nut 114 is threadedly connected to the threaded section. When the support shaft 108 is inserted into the mounting groove 104, the nut 114 is threadedly connected to the threaded section 128 and pressed against the side of the locking plate 120 away from the backrest 106, and a special-shaped hole 134 matching the shape of the special-shaped section is provided on the locking plate 120, and a friction gasket 116 is sleeved on the optical axis section 132.

[0050] In the embodiment of the present invention, firstly, one end of the support shaft 108, that is, the end away from the backrest 106, is designed with several different parts: a threaded section 128, a special-shaped section 130 and a smooth shaft section 132. This design not only makes the support shaft structurally stable, but also facilitates its connection with other components.

[0051] The main function of the threaded section 128 is to connect the nut 114. When the nut 114 is threadedly connected to the threaded section 128, it will press the locking plate 120 away from the side of the backrest 106. In this way, the locking plate 120 is fixed on the support shaft 108 to form a stable structure.

[0052] The special-shaped section 130 is designed to match the special-shaped hole 134 on the locking plate 120. The design of the special-shaped hole 134 can ensure that the position of the locking plate 120 on the support shaft 108 is fixed and will not slide or rotate at will. In this way, the entire structure has a higher stability. At the same time, when the locking plate 120 is pressed by the nut 114, the locking plate 120 can simultaneously press the friction pad 116, thereby ensuring that the support shaft 108 will not rotate relative to the rotating mounting groove 104, and further ensuring that the backrest 106 will not rotate relative to the seat cushion 100.

[0053] The optical axis section 132 is used for mounting the friction gasket 116. The main function of the friction gasket 116 is to increase the friction between the support shaft 108 and other components to prevent them from loosening or sliding during use.

[0054] When the support shaft 108 is inserted into the mounting groove 104, the entire structure is firmly connected together. The compression effect of the nut 114, the fixing effect of the locking disk and the anti-skid effect of the friction pad together ensure the stability and reliability of the support shaft.

[0055] like Fig.10 As shown, according to one embodiment of the present invention, the optical axis segment corresponds to the position of the mounting groove 104 and the diameter of the threaded segment is smaller than the diameter of the optical axis segment, and a clamping protrusion 122 is provided on the side of the nut 114 facing the locking disk 120 .

[0056] In the embodiment of the present invention, the optical axis section corresponds to the position of the mounting slot 104, which means that the optical axis section is designed to be inserted into the mounting slot 104. This design enables the support shaft to be stably installed in the desired position without shaking or offsetting.

[0057] The diameter of the threaded section is smaller than the diameter of the optical axis section. This design has two considerations: first, it is convenient for tightening the nut 114, because the threaded section has a smaller diameter, the nut can be more easily tightened on the threaded section; second, it increases the overall stability of the support shaft, because the optical axis section has a larger diameter, it can provide better support and reduce the deformation of the structure when it is subjected to force.

[0058] A pressing protrusion 122 is provided on the side of the nut 114 facing the locking disk 120. The function of the pressing protrusion 122 is to pre-press the locking disk 120, thereby increasing the pressing force of the nut 114 on the locking disk 120, thereby ensuring that the nut 114 can more firmly press the locking disk 120. This design helps prevent the locking disk from loosening or falling off during use, and improves the stability and reliability of the entire structure. Figure 6As shown, according to one embodiment of the present invention, a first friction surface 124 is provided on the side of the friction pad 116 facing the locking plate 120, and a second friction surface 126 is provided on the side of the locking plate 120 facing the locking plate 120. When the locking plate 120 and the friction pad 116 are in contact, the first friction surface 124 and the second friction surface 126 are frictionally matched.

[0059] Specifically, the first locking structure is: First, the side of the friction pad 116 facing the locking plate 120 is provided with a first friction surface 124, and the side of the locking plate 120 facing the friction pad 116 is provided with a second friction surface 126. When the locking plate 120 and the friction pad 116 are in contact, the two friction surfaces will fit closely together.

[0060] This design enables friction to be generated between the first friction surface 124 and the second friction surface 126. When an external force acts on the support shaft, the friction between the friction pad 116 and the locking plate 120 will act as a resistance to prevent the support shaft from sliding or rotating. This friction fit mechanism helps to ensure the stability and reliability of the support shaft, especially when it needs to withstand a large load or impact.

[0061] In addition, by properly selecting the type and properties of the friction material, the friction coefficient between the first friction surface 124 and the second friction surface 126 can be adjusted to meet the needs of different application scenarios. For example, in situations where higher friction is required, a material with a higher friction coefficient can be selected; and in situations where reduced friction is required, a material with a lower friction coefficient can be selected.

[0062] According to an embodiment of the present invention, the locking structure further includes an anti-loosening washer, and the anti-loosening washer is sleeved on a side of the friction washer 116 away from the backrest 106 .

[0063] In the embodiment of the present invention, the anti-loosening washer is sleeved on the side of the friction washer 116 away from the backrest 106. This position arrangement enables the anti-loosening washer to fit tightly between the friction washer 116 and the locking plate 120 to form a stable supporting structure.

[0064] The main function of the anti-loosening gasket is to prevent the locking structure from loosening due to vibration or external force during long-term use. Its material and design are carefully selected and optimized to ensure that it has good elasticity and wear resistance. When the seat is subjected to external impact or vibration, the anti-loosening gasket can effectively absorb and disperse these forces, reduce their impact on the locking structure, and thus maintain the stability and reliability of the entire structure.

[0065] In addition, the introduction of the anti-loosening gasket also enhances the overall strength of the locking structure. It not only provides additional support, but also increases the contact area between the locking structure and the support shaft 108, thereby improving the firmness of the connection. This makes the seat more stable when bearing weight or pressure, and is less likely to deform or damage.

[0066] In summary, the embodiments of the present invention further improve the locking structure of the flap-type seat by introducing the innovative component of the anti-loosening gasket. This design not only improves the stability and safety of the seat, but also extends its service life, providing users with a more high-quality and reliable seat experience.

[0067] According to one embodiment of the present invention, a passive tooth is provided on the support shaft 108, and an active tooth and a reducer and a driving member connected to the active tooth are provided on the seat cushion 100. When the support shaft 108 is inserted into the mounting groove 104, the active tooth is connected to the driven tooth.

[0068] Specifically, the second structure of the locking structure is: The support shaft 108 is provided with a passive tooth, and the seat cushion 100 is provided with an active tooth and a reducer and a driving member connected to the active tooth. This design enables the active tooth to be connected to the driven tooth when the support shaft 108 is inserted into the mounting slot 104, thereby providing the seat with an electric adjustment function.

[0069] Specifically, the passive teeth enable the support shaft 108 to not only connect and support, but also to cooperate with the drive system. When the support shaft 108 is correctly installed in the installation slot 104, the passive teeth mesh with the active teeth on the seat cushion 100, forming a stable transmission relationship.

[0070] The driving gear on the seat cushion 100 is connected to the reducer and the driving member. The main function of the reducer is to reduce the output speed of the driving member and increase the output torque to adapt to the force and speed required for seat adjustment. The driving member can be a motor or other power source to provide power for the entire adjustment system.

[0071] By controlling the operation of the driving member, the angle of the backrest 106 can be conveniently adjusted. When the user needs to adjust the angle of the backrest 106, he only needs to operate the corresponding control device, and the driving member will start working, driving the passive gear to rotate through the reducer and the active gear, thereby achieving the angle adjustment of the backrest 106.

[0072] This electric adjustment design not only makes the seat adjustment process more convenient and efficient, but also improves the user experience. Users no longer need to manually adjust the 106 degree angle of the backrest, but can easily complete the adjustment with just a light touch.

[0073] In addition, the design also takes energy consumption and noise into consideration. By optimizing the performance of the reducer and drive components, energy consumption and noise can be effectively reduced, making the seat more energy-efficient and quieter during adjustment.

[0074] According to an embodiment of the present invention, a protective sleeve 118 is further included, and the protective sleeve 118 is sleeved on the upper mounting seat 102 .

[0075] In the embodiment of the present invention, the presence of the cover 118 not only provides an additional protective layer for the seat, reduces wear and damage caused by daily use or external factors, but also improves the overall aesthetics of the seat. The cover 118 can be made of a soft, wear-resistant, and easy-to-clean material to provide users with a more comfortable and pleasant use experience.

[0076] At the same time, the design of the cover 118 also takes into account the convenience and stability of installation. It can be easily mounted on the upper mounting seat 102, and ensured to be stable and not fall off through appropriate fixing methods (such as sewing, buckles, etc.). In this way, users can feel convenient and comfortable when installing, using and maintaining the seat.

[0077] In addition, the color, pattern and material of the cover 118 can also be customized according to the user's preferences and needs, making the seat more in line with the user's aesthetics and usage habits.

[0078] In summary, the embodiment of the present invention not only improves the comfort and aesthetics of the flip-type seat by adding the design element of the cover 118, but also provides the user with a more convenient and personalized use experience. This innovative design makes the seat more in line with the lifestyle and aesthetic needs of modern people.

[0079] A second aspect of the present invention provides a passenger device, including the above-mentioned flip-type seat.

[0080] According to the passenger equipment provided by the embodiment of the second aspect of the present invention, by providing the above-mentioned flip-up seat, it is convenient for users to adjust the installation direction of the backrest 106, saving space for seat adjustment, realizing the diversified uses of the passenger equipment, and satisfying the user's demand for flexibly adjusting the direction of the seat.

[0081] The passenger equipment provided in the embodiment of the second aspect of the present invention may be a road vehicle, a railway vehicle, etc.
