Description

Technical Field

[0001] The present invention relates to a seat module and a passenger device, and in particular to a seat module with a simple structure, low cost and light weight, and a passenger device equipped with the seat module. Background Art

[0002] A stroller is a tool used by parents to carry babies or children while they are out shopping or window-shopping. Currently, most strollers have a calf rest, which is usually designed at the front end of the seat. Therefore, when a baby rides in a stroller, the baby's legs can be supported by the calf rest, making the ride more comfortable for the baby. Generally speaking, the angle of the calf rest can be adjusted by means of an adjustment structure. The operating member of the existing adjustment structure is mostly pivotally connected to the calf rest by rivets, and the reset of the operating member is achieved by a spring. Since the operating member, rivet and spring are all independent components, the existing adjustment structure is relatively complex, costly and heavy. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a seat module with a simple structure, low cost and light weight, and a passenger device equipped with the seat module, in order to overcome the deficiencies of the prior art and solve the above problems.

[0004] The seat module of the present invention adopts the following technical solutions:

[0005] The seat module includes a seat body, a calf rest and an operating member. The seat body has a first engaging portion. The calf rest is pivotally connected to the seat body. The operating member has a pressing portion, an elastic portion, a pivoting portion and a second engaging portion. The operating member is pivotally connected to the calf rest via the pivoting portion. The elastic portion abuts against the calf rest. The second engaging portion engages with the first engaging portion so that the calf rest is maintained in a predetermined position. When the pressing portion is pressed, the elastic portion is squeezed and elastically deformed, and the second engaging portion disengages from the first engaging portion, so that the calf rest can rotate relative to the seat body to adjust the angle of the calf rest. When the pressing portion is released, the elastic portion resets the operating member.

[0006] Preferably, the elastic portion is a spring piece integrally formed on the operating member.

[0007] Preferably, the first engaging portion protrudes from the front lower edge of the seat body.

[0008] Preferably, when the calf rest rotates relative to the seat body, the second engaging portion abuts against the front lower edge of the seat body.

[0009] Preferably, when the calf rest is maintained at the predetermined position, the calf rest is level with the seat body.

[0010] The passenger device of the present invention adopts the following technical solutions:

[0011] The passenger device includes a vehicle frame and a seat module. The seat module includes a seat body, a calf rest and an operating member. The seat body is pivotally connected to the vehicle frame, and the seat body has a first engaging portion. The calf rest is pivotally connected to the seat body. The operating member has a pressing portion, an elastic portion, a pivoting portion and a second engaging portion. The operating member is pivotally connected to the calf rest via the pivoting portion. The elastic portion abuts the calf rest. The second engaging portion engages with the first engaging portion so that the calf rest is maintained in a predetermined position. When the pressing portion is pressed, the elastic portion is squeezed and elastically deformed, and the second engaging portion disengages from the first engaging portion, so that the calf rest can rotate relative to the seat body to adjust the angle of the calf rest. When the pressing portion is released, the elastic portion resets the operating member.

[0012] Preferably, the elastic portion is a spring piece integrally formed on the operating member.

[0013] Preferably, the first engaging portion protrudes from the front lower edge of the seat body.

[0014] Preferably, when the calf rest rotates relative to the seat body, the second engaging portion abuts against the front lower edge of the seat body.

[0015] Preferably, when the calf rest is maintained at the predetermined position, the calf rest is level with the seat body.

[0016] Preferably, the frame includes a rider, a rear leg, a front leg, a fixing member, a first seat linkage, and a second seat linkage. The front leg is pivotally connected to the rear leg, the seat body is pivotally connected to the front leg, the fixing member is disposed on the rear side of the seat and connected to one end of the rider, the first seat linkage is pivotally connected to the seat and the fixing member, and the second seat linkage is pivotally connected to the seat and the rear leg. When the rider, rear leg, and front leg are relatively retracted, the fixing member and the rear leg respectively drive the rear side of the seat body to flip in the opposite direction toward the ground via the first seat linkage and the second seat linkage. When the rider, rear leg, and front leg are relatively unfolded, the fixing member and the rear leg respectively drive the rear side of the seat body to be positioned in the direction toward the ground via the first seat linkage and the second seat linkage.

[0017] Preferably, after the seat body is folded, the front side of the seat body is lower than the rear side of the seat body.

[0018] Therefore, according to the above technical solutions, the passenger device and seat module of the present invention have at least the following advantages and beneficial effects: The operating member of the seat module of the present invention is pivotally connected to the calf rest via its own pivotal connection, and the operating member is reset by its own elastic portion. Therefore, the present invention does not require additional rivets and springs; the pivotal connection and elastic portion can be integrally formed on the operating member, resulting in a simple structure, cost savings, and light weight. When the passenger device of the present invention is folded, the first and second seat linkages drive the rear side of the seat to flip in opposite directions toward the ground, causing the front side of the seat to be lower than the rear side. Generally speaking, the rear side of the seat is the boundary between the seat and the backrest. Therefore, when the passenger device of the present invention is folded, the boundary between the seat and the backrest reaches its highest point, preventing the backrest from touching the ground when the passenger device is folded. Consequently, the backrest can be made longer according to actual needs. Furthermore, when the passenger device of the present invention is folded, the seat flips downward, reducing the height of the folded passenger device, facilitating storage or transportation of the passenger device.

[0061] like Figure 1 As shown, the passenger device 1 of the present invention includes a frame 10 and a seat module 12. The passenger device 1 can be a baby carriage or other device that can be used for riding. The seat module 12 is pivotally connected to the frame 10 so that the seat module 12 can be folded or unfolded together with the frame 10. In this embodiment, the frame 10 may include a rider 100, a rear foot 102, and a front foot 104. The rider 100, the rear foot 102, and the front foot 104 are pivotally connected to each other so that the rider 100, the rear foot 102, and the front foot 104 can be pivoted to each other to be folded or unfolded. In this embodiment, the frame 10 may also include a folding operating member 106. The folding operating member 106 may be provided on the rider 100. The user can operate the folding operating member 106 to fold the passenger device 1.

[0062] like Figures 2 to 5 As shown, the seat module 12 includes a seat body 120, a calf rest 122 and an operating member 124. The seat body 120 is pivotally connected to the vehicle frame 10, and the seat body 120 has a first engaging portion 1200. In the present embodiment, the first engaging portion 1200 may protrude from the front lower edge 1202 of the seat body 120. The calf rest 122 is pivotally connected to the seat body 120. In the present embodiment, there are two calf rests 122 pivotally connected to two opposite sides of the front side of the seat body 120. The operating member 124 has a pressing portion 1240, an elastic portion 1242, a pivoting portion 1244 and a second engaging portion 1246. The operating member 124 is pivotally connected to the calf rest 122 via the pivoting portion 1244. In the present embodiment, the pivoting portion 1244 may be a protruding column (such as Figure 6As shown), the middle section of the calf support 122 may have a pivot hole 1220. The pivot portion 1244 may be inserted into the pivot hole 1220 so that the operating member 124 is pivotally connected to the calf support 122.

[0063] like Figure 3 、 Figure 5 and Figure 6 As shown, in this embodiment, the elastic portion 1242 may be a spring formed integrally with the operating member 124. When the operating member 124 is pivotally connected to the calf rest 122, the elastic portion 1242 abuts against the inner surface of the calf rest 122. In this embodiment, the elastic portion 1242 and the pivoting portion 1244 may be located between the pressing portion 1240 and the second engaging portion 1246, and the elastic portion 1242 may be adjacent to the pivoting portion 1244.

[0064] like Figure 5 As shown, the second engaging portion 1246 of the operating member 124 can engage with the first engaging portion 1200 of the seat body 120, so that the calf support 122 is maintained at a predetermined position. Figure 5 When in the predetermined position shown, the calf rest 122 is horizontal with the seat body 120. When the user wants to adjust the angle of the calf rest 122, the user can press the pressing portion 1240 of the operating member 124 in the direction of arrow A1. When the pressing portion 1240 of the operating member 124 is pressed, the operating member 124 will rotate in the direction of arrow A2 with the pivot portion 1244 as the axis. At this time, the elastic portion 1242 will be squeezed by the inner surface of the calf rest 122 to produce elastic deformation, and the second engaging portion 1246 will disengage from the first engaging portion 1200, so that the calf rest 122 can be rotated relative to the seat body 120 in the direction of arrow A3 to adjust the angle of the calf rest 122. For example, when the second engaging portion 1246 disengages from the first engaging portion 1200, the user can rotate the calf rest 122 in the direction of arrow A3 to Figure 3 When the user wants to put the lower leg against 122 Figure 3 Adjust the position shown to Figure 5 In the position shown, the user can push the calf support 122 directly in the direction of arrow A2.

[0065] like Figure 3 and Figure 5 As shown, the elastic portion 1242 of the operating member 124 abuts against the inner surface of the calf support 122. Therefore, when the pressing portion 1240 of the operating member 124 is moved toward Figure 3When pressed in the direction of the arrow A1 shown, the elastic portion 1242 will be squeezed by the inner surface of the calf rest 122 and elastically deformed. When the pressing portion 1240 of the operating member 124 is released, the elastic force of the elastic portion 1242 will cause the operating member 124 to rotate in the direction of the arrow A3 and reset. Therefore, when the calf rest 122 rotates relative to the seat body 120, the elastic force of the elastic portion 1242 will cause the second engaging portion 1246 of the operating member 124 to abut against the front lower edge 1202 of the seat body 120. In this embodiment, the front lower edge 1202 of the seat body 120 can be arc-shaped. Therefore, the second engaging portion 1246 of the operating member 124 can slide smoothly along the front lower edge 1202 of the seat body 120, so that the calf rest 122 can rotate smoothly relative to the seat body 120. In addition, when the calf rest 122 is located Figure 5 When in the position shown, the elastic force of the elastic portion 1242 also enables the second engaging portion 1246 of the operating member 124 to maintain a stable engagement with the first engaging portion 1200 of the seat body 120 .

[0066] Please refer to Figures 7 to 11 , Figure 7 yes Figure 1 A side view of the passenger device 1 in FIG. Figure 8 yes Figure 1 A perspective view of the riding device 1 in a semi-folded state, Figure 9 yes Figure 8 A side view of the passenger device 1 in FIG. Figure 10 yes Figure 1 A perspective view of the passenger device 1 after folding, Figure 11 yes Figure 10 It should be noted that the riding device 1 of the present invention is generally a bilaterally symmetrical structure, and the following describes the technical features of the present invention using the structure of one side.

[0067] like Figure 1 、 Figures 7 to 11 As shown, in this embodiment, the rider 100 may include an upper rider handle 1000, a first lower rider handle 1002, and a second lower rider handle 1004. The first lower rider handle 1002 and the second lower rider handle 1004 are respectively pivotally connected to the upper rider handle 1000, so that the upper rider handle 1000, the first lower rider handle 1002, and the second lower rider handle 1004 can pivot relative to each other to fold or unfold. A folding operating member 106 may be disposed on the upper rider handle 1000. The ride device 1 may also include a locking mechanism 108. The user can operate the folding operating member 106 to fold the ride device 1. The locking mechanism 108 may be disposed at the pivotal connection between the upper rider handle 1000 and the second lower rider handle 1004 to lock or unlock the upper rider handle 1000 and the second lower rider handle 1004.

[0068] like Figure 1 、 Figures 7 to 11As shown, the frame 10 may further include a fixing member 110, a first seat linkage 112, and a second seat linkage 114. The fixing member 110 is disposed on the rear side 1206 of the seat body 120 and is connected to one end of the second lower handlebar 1004 of the rider 100. In this embodiment, the rear leg 102 may include a connecting member 1020. The front leg 104 and the first lower handlebar 1002 of the rider 100 are respectively pivotally connected to two sides of the connecting member 1020 of the rear leg 102, allowing the front leg 104 and the first lower handlebar 1002 of the rider 100 to pivot relative to the rear leg 102 to be folded or unfolded. The seat body 120 is pivotally connected to the front leg 104. The first seat linkage 112 has two ends pivotally connected to the seat body 120 and the fixing member 110, respectively. The second seat linkage 114 has two ends pivotally connected to the seat body 120 and the rear leg 102, respectively. In this embodiment, the first seat linkage component 112 and the second seat linkage component 114 can be iron sheets, but the present invention is not limited thereto.

[0069] like Figure 1 、 Figure 8 and Figure 10 As shown, the seat body 120 has a front side 1204 and a rear side 1206. The calf support 122 is pivotally connected to the front side 1204 of the seat body 120, so that the calf support 122 can be pivoted relative to the seat body 120 to adjust the angle. In addition, the passenger device 1 may also include a backrest 14 (such as Figure 11 Generally speaking, the backrest 14 is disposed at the rear side 1206 of the seat body 120 . Therefore, the rear side 1206 of the seat body 120 is the boundary between the seat body 120 and the backrest 14 .

[0070] like Figure 1 、 Figures 7 to 11 As shown, the rider 100, rear leg 102 and front leg 104 can be relatively folded or unfolded to drive the seat body 120 to fold or unfold. Further, when the rider 100, rear leg 102 and front leg 104 are relatively folded or unfolded, the fixing member 110 and rear leg 102 will respectively drive the seat body 120 to fold or unfold via the first seat linkage member 112 and the second seat linkage member 114. Figure 10 and Figure 11As shown, when the rider 100, the rear foot 102 and the front foot 104 are relatively folded, the fixing member 110 and the rear foot 102 will respectively drive the rear side 1206 of the seat body 120 to flip in the opposite direction of the ground (the direction of arrow A4) through the first seat linkage 112 and the second seat linkage 114. Therefore, after the seat body 120 is folded, the seat body 120 will flip downward in the direction of arrow A4, so that the front side 1204 of the seat body 120 will be lower than the rear side 1206 of the seat body 120. As mentioned above, the rear side 1206 of the seat body 120 is the dividing line between the seat body 120 and the backrest 14. Therefore, in other words, after the seat body 120 is folded, the dividing line between the seat body 120 and the backrest 14 will reach the highest point, so that the backrest 14 will not touch the ground after the passenger device 1 is folded. Therefore, the backrest 14 can be made longer according to actual needs. As Figure 10 and Figure 11 As shown, after the riding device 1 is folded, the seat body 120 flips downward in the direction of arrow A4, thereby reducing the height of the folded riding device 1 and facilitating storage or transportation of the riding device 1. Furthermore, when the rider 100, the rear leg 102, and the front leg 104 are relatively unfolded, the fixing member 110 and the rear leg 102 are driven by the first seat linkage 112 and the second seat linkage 114, respectively, to position the rear side 1206 of the seat body 120 toward the ground (in the direction of arrow A5).

[0071] Therefore, according to the above technical solutions, the passenger device and seat module of the present invention have at least the following advantages and beneficial effects: The operating member of the seat module of the present invention is pivotally connected to the calf rest via its own pivotal connection, and the operating member is reset by its own elastic portion. Therefore, the present invention does not require additional rivets and springs; the pivotal connection and elastic portion can be integrally formed on the operating member, resulting in a simple structure, cost savings, and light weight. When the passenger device of the present invention is folded, the first and second seat linkages drive the rear side of the seat to flip in opposite directions toward the ground, causing the front side of the seat to be lower than the rear side. Generally speaking, the rear side of the seat is the boundary between the seat and the backrest. Therefore, when the passenger device of the present invention is folded, the boundary between the seat and the backrest reaches its highest point, preventing the backrest from touching the ground when the passenger device is folded. Consequently, the backrest can be made longer according to actual needs. Furthermore, when the passenger device of the present invention is folded, the seat flips downward, reducing the height of the folded passenger device, facilitating storage or transportation of the passenger device.

[0072] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
