Technical Field

[0001] The present application relates to the field of children's products, and in particular to a children's stroller. Background Art

[0002] Currently, more and more strollers are equipped with trays to conveniently store cups, bottles, food, and other items, thereby reducing the burden on parents. However, to facilitate removal or folding, the trays are often not fixed to the stroller frame, which can cause the trays to wobble, causing items on the trays to fall and even injure the baby. Utility Model Content

[0003] The main purpose of the present application is to provide a children's stroller that can make the installation of the dining tray assembly more stable.

[0004] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0005] A baby stroller, including a seat assembly and a dining tray assembly;

[0006] The seat assembly includes a first mounting portion;

[0007] The dining tray assembly includes a second mounting portion, which is detachably connected to the first mounting portion;

[0008] Among them, the direction from the second mounting part to the first mounting part is the first direction, one of the first mounting part and the second mounting part is provided with a first protrusion that can be telescopically set along the first direction, and the other is provided with a first groove body, the first protrusion extends into the first groove body to limit the relative displacement of the first mounting part and the second mounting part along the direction perpendicular to the first direction; a first hook is provided on the first protrusion, and a second hook is provided on the groove surface of the first groove body. Along the first direction, the first hook and the second hook abut against each other or are spaced from each other to limit the relative displacement of the first mounting part and the second mounting part along the first direction.

[0009] In some embodiments, the first hook extends in the opposite direction of the gravity direction and in the first direction, and the second hook extends in the opposite direction of the gravity direction and in the first direction.

[0010] In the above embodiment, the extension arrangement of the first hook and the second hook makes them both extend obliquely, so that the first hook and the second hook can abut against each other and the connection and separation of the first hook and the second hook are more convenient.

[0011] In some embodiments, along the first direction, a side of the first hook facing away from the second hook abuts against or is spaced apart from the bottom wall defining the first slot to limit relative displacement of the first mounting portion and the second mounting portion in the opposite direction along the first direction.

[0012] In the above embodiment, the relative displacement between the first mounting portion and the second mounting portion in the opposite direction along the first direction can be limited, thereby achieving a more comprehensive limiting effect.

[0013] In some embodiments, the bottom wall has a first opening, and at least a portion of the first protrusion can extend into the first opening along the first direction.

[0014] In the above embodiment, a larger displacement space can be provided for the second mounting portion without additionally increasing the size of the first slot body along the first direction.

[0015] In some embodiments, the first mounting portion is provided with a first groove body and the second mounting portion is provided with a first protrusion. Along the first direction, the first hook is located at the end of the first protrusion close to the first mounting portion, and the second hook is located at the groove surface defining the first groove body close to the end of the second mounting portion.

[0016] In the above embodiment, the structures of the first protrusion and the first groove body can be simplified, the manufacturing cost can be reduced, and the assembly and disassembly of the first protrusion and the first groove body can be more convenient.

[0017] In some embodiments, one of the first mounting portion and the second mounting portion is further provided with a second protrusion, and the other is provided with a second groove, and the second protrusion extends into the second groove along the direction of gravity so that the first mounting portion abuts against the second mounting portion in the opposite direction of gravity.

[0018] In the above embodiment, the displacement of the dining tray assembly along the direction of gravity can be limited, making the installation of the dining tray assembly more stable.

[0019] In some embodiments, the second direction is perpendicular to the first direction and the direction of gravity, and along the direction of gravity, the size of the second protrusion along the second direction and the size of the second groove along the second direction both gradually increase.

[0020] In the above embodiment, when the second protrusion extends into the second groove body along the direction of gravity, the second protrusion can gradually stick to the groove wall of the second groove body, so that the two form an abutment effect along the direction of gravity and make the force more stable.

[0021] In some embodiments, the first mounting portion is provided with a first groove body, the second mounting portion is provided with a first protrusion, and the second mounting portion further includes a pressing member, a locking seat, an elastic member and a first connecting seat. The first connecting seat has a second opening. Along the first direction, the second mounting portion and the pressing member are both connected to the side of the locking seat close to the first mounting portion at one end, and the other end is passed through the second opening, and one end of the elastic member abuts against the side of the locking seat away from the first mounting portion, and the other end abuts against the first connecting seat.

[0022] In the above embodiment, the telescopic movement of the first protrusion along the first direction can be easily controlled.

[0023] In some embodiments, the locking seat further has a reinforcement protrusion on one side close to the first mounting portion along the first direction, and the reinforcement protrusion is connected to the second mounting portion.

[0024] In the above embodiment, the connection strength between the second mounting portion and the locking seat can be increased.

[0025] In some embodiments, the seat assembly further includes a first frame and a second frame, the first frame includes a first pushing portion, the first mounting portion includes a second pushing portion, the first frame is rotatably connected to the second frame, and during the rotation of the first frame relative to the second frame, the first pushing portion is configured to push the second pushing portion so that both the first mounting portion and the dining tray assembly rotate relative to the second frame.

[0026] In the above embodiment, the seat assembly and the dining tray assembly are both rotatable, thereby achieving a folding effect of the seat assembly and the dining tray assembly. While the first pushing portion pushes the second pushing portion, the relative positions of the first mounting portion and the second mounting portion are fixed, so that the dining tray assembly can move accordingly, thereby achieving the effect of driving the dining tray assembly to rotate and fold.

[0027] In some embodiments, the first frame also includes a third connecting seat, the third connecting seat has a third groove body, the outer side wall of the third groove body and the first mounting portion both extend around a rotation axis parallel to the first direction, the first mounting portion extends into the third groove body, the first pushing portion is connected to the connecting seat and is at least partially located in the third groove body, the first pushing portion and the second pushing portion are both strip-shaped, and the first pushing portion and the second pushing portion both extend radially along the rotation axis.

[0028] In the above embodiment, the coaxially rotating first mounting portion and the first frame can form a pushing effect through the first pushing portion and the second pushing portion extending radially inward while rotating, so that the pushing force is easier to control and more stable.

[0029] In some embodiments, the first frame is configured to rotate relative to the second frame along a first circumferential direction around an axis parallel to the first direction, and the first pushing portion can abut the second pushing portion in a direction away from the direction of gravity, so that the first mounting portion and the dining tray assembly both rotate in the opposite direction of the first circumferential direction relative to the second frame.

[0030] In the above embodiment, the folding movement of the first frame and the dining tray assembly can be made more reasonable, and is conducive to saving space.

[0031] In some embodiments, the seat assembly further includes a pushing portion configured to reciprocate in a first direction so that the pushing portion has a locking position and an unlocking position. The first frame further includes a third connecting seat having a third groove, and the first mounting portion has a fourth groove. When the pushing portion is in the locking position, the pushing portion extends into the third groove and the fourth groove to fix the relative positions among the first frame, the first mounting portion, and the dinner plate assembly. When the pushing portion is in the unlocking position, the pushing portion disengages from the third groove and extends into the fourth groove so that the first pushing portion can push the second pushing portion.

[0032] In the above embodiment, the rotational pushing action between the first pushing portion and the second pushing portion is locked by the movement of the pushing portion.

[0033] Compared with the prior art, the beneficial effects of the present application are as follows:

[0034] The baby carriage of the present application includes a seat assembly and a dinner plate assembly. Based on the settings of the first protrusion and the first groove, the relative displacement between the first mounting portion and the second mounting portion in a direction perpendicular to the first direction can be restricted. By using the first hook provided on the first protrusion and the second hook provided on the groove surface of the first groove, the relative displacement between the first mounting portion and the second mounting portion in the first direction can be further restricted. Compared with the connection forms in the related art that only adopt snap connection or only adopt sliding connection, the present application adds the cooperation between the first hook and the second hook on the basis of the fitting connection of the first protrusion extending into the first groove to further prevent the dinner plate assembly from loosening. Therefore, the baby carriage of the present application can make the installation of the dinner plate assembly more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The realization of the purpose of this application, its functional features and advantages will be further described in conjunction with the embodiments and with reference to the accompanying drawings. Detailed implementation manners

[0058] The following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without making creative efforts fall within the scope of protection of this application.

[0059] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of this application, such directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, then the directional indications will also change accordingly.

[0060] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of this application, such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or", "or / and" or "and / or" appear throughout the text, their meanings include three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution where A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0061] Currently, more and more baby carriages are provided with a dining plate to facilitate placing water cups, milk bottles, food and various other items, thus reducing the carrying burden on parents. To facilitate disassembly or folding, the dining plate is often not fixedly connected to the frame, so the dining plate is prone to shaking problems, and then the items on the dining plate are likely to fall off, and even cause situations such as hurting babies.

[0062] More specifically, in the related art, the connection between the dinner plate and the vehicle frame often adopts snap connection or sliding connection with a sliding groove and a slider. Among them, the snap connection method is not firm enough and is still prone to shaking. While the sliding connection method makes it difficult to stably connect the dinner plate in multiple directions. For example, when the sliding installation direction is the gravity direction, if the sliding groove is required to limit the slider in both the left-right direction and the front-back direction at the same time, a closed sliding groove around is needed to cooperate with the slider, making the connection structure relatively complex and having a high requirement for manufacturing accuracy. If an open sliding groove that is not closed is set, the degree of freedom of the dinner plate will lack limitation, making the dinner plate prone to shaking relative to the vehicle frame when the baby carriage is in normal use or folded.

[0063] In view of this, referring to Figures 1 - 9 , in an embodiment of the present application, a baby carriage 100 is provided, which includes a seat assembly 110 and a dinner plate assembly 120. The seat assembly 110 includes a first mounting portion 111; the dinner plate assembly 120 includes a second mounting portion 121, and the second mounting portion 121 is detachably connected to the first mounting portion 111. Among them, the seat assembly 110 can be only the frame of the baby carriage 100, that is, the vehicle frame part; it can also be only the seat part of the baby carriage 100; it can also be a combination of the vehicle frame part and the seat part of the baby carriage 100. For the convenience of description, the following will take the embodiment in which the seat assembly 110 is only the vehicle frame part of the baby carriage 100 as an example. In addition, the dinner plate assembly 120 can include a bearing portion for bearing various suitable items. Corresponding to this function, the bearing portion can have any suitable structural shape, which is not limited here.

[0064] For the specific connection form between the first mounting portion 111 and the second mounting portion 121, refer to Figures 1 - 5, the direction from the second mounting portion 121 to the first mounting portion 111 is defined as the first direction X below. For ease of description, the following examples are described with the first direction X corresponding to the left-right direction perpendicular to the front-rear direction and the gravity direction Z of the stroller 100. Based on this, one of the first mounting portion 111 and the second mounting portion 121 is provided with a first protrusion 1211 that can be telescopically arranged along the first direction X, and the other is provided with a first groove 1111. For ease of description, the following examples are described with the first mounting portion 111 being provided with the first groove 1111 and the second mounting portion 121 being provided with the first protrusion 1211. Different embodiments can be combined with different technical solutions. The first protrusion 1211 extends into the first groove 1111 to limit the relative displacement of the first mounting portion 111 and the second mounting portion 121 in a direction perpendicular to the first direction X. It can be understood that the side walls defining the first groove 1111 can face the first protrusion 1211 in multiple directions perpendicular to the first direction X, so as to avoid relative movement between the first mounting portion 111 and the second mounting portion 121 in a direction perpendicular to the first direction X, that is, to avoid loosening of the dinner plate assembly 120 relative to the seat assembly 110. It should be noted that in this application, loosening can be either detachment or looseness.

[0065] Specifically, based on the above-mentioned limiting setting, refer to Figure 3 , a first hook 12111 is provided on the first protrusion 1211, and a second hook 11111 is provided on the groove surface defining the first groove 1111. Along the first direction X, the first hook 12111 and the second hook 11111 are in contact with each other or spaced apart from each other. In other words, one side of the first hook 12111 can be in contact with the second hook 11111, so that the above setting can limit the relative displacement of the first mounting portion 111 and the second mounting portion 121 along the first direction X. It can be understood that when the second mounting portion 121 moves relative to the first mounting portion 111 along the first direction X (the first direction X is defined as the direction in which the first protrusion 1211 extends out of the first groove 1111), the cooperation connection between the first hook 12111 and the second hook 11111 limits the movement of the second mounting portion 121, thereby further avoiding loosening of the dinner plate assembly 120 relative to the seat assembly 110.

[0066] In addition, it should be noted that in some embodiments, the mounting structures (such as the first mounting portion 111 and the second mounting portion 121) of the seat assembly 110 and the dinner plate assembly 120 can include two groups, and the two groups of mounting structures are symmetrically arranged in the left-right direction of the stroller 100, so as to achieve a multi-directional support connection effect and make the installation of the dinner plate assembly 120 more stable.

[0067] According to the combination of the above embodiments, it can be seen that the baby stroller 100 of the present application includes a seat assembly 110 and a dining plate assembly 120. Based on the settings of the first protrusion 1211 and the first groove 1111, the relative displacement of the first mounting portion 111 and the second mounting portion 121 in a direction perpendicular to the first direction X can be restricted. By using the first hook 12111 provided on the first protrusion 1211 and the second hook 11111 provided on the groove surface of the first groove 1111, the relative displacement of the first mounting portion 111 and the second mounting portion 121 in the first direction X can be further restricted. Compared with the connection forms that only use snap connection or only use sliding connection in the related art, on the basis of the first protrusion 1211 extending into the first groove 1111 for mating connection, the present application adds the cooperation between the first hook 12111 and the second hook 11111 to further prevent the dining plate assembly 120 from loosening. Therefore, the baby stroller 100 of the present application can make the installation of the dining plate assembly 120 more stable.

[0068] Regarding the structural settings of the first hook 12111 and the second hook 11111, define the second direction Y perpendicular to the first direction X. Combining with the embodiment where the first direction X is the left-right direction of the baby stroller 100, the second direction Y can correspond to the front-back direction of the baby stroller. Therefore, for the convenience of description, the following will all take the embodiment where the second direction Y is the front-back direction of the baby stroller 100 as an illustration. Based on this, refer to Figure 3 , in some embodiments, the first hook 12111 extends along the reverse direction of the gravity direction Z and the first direction X, and the second hook 11111 extends along the gravity direction Z and the reverse direction of the first direction X. It can be understood that the above-mentioned extension settings of the first hook 12111 and the second hook 11111 make both of them extend obliquely, so that while the first hook 12111 and the second hook 11111 can abut against each other, it also makes the connection and disassembly between the first hook 12111 and the second hook 11111 more convenient.

[0069] In addition to restricting the relative displacement of the first mounting portion 111 and the second mounting portion 121 in the first direction X by the abutting action between the first hook 12111 and the second hook 11111, in order to play a more comprehensive limiting role, refer to Figure 3In some embodiments, along the first direction X, a side of the first hook 12111 facing away from the second hook 11111 abuts against or is spaced apart from the bottom wall 1112 defining the first slot 1111. In other words, the side of the first hook 12111 facing away from the second hook 11111 can abut against the bottom wall 1112 defining the first slot 1111. Thus, the above arrangement can limit relative displacement between the first mounting portion 111 and the second mounting portion 121 in the opposite direction of the first direction X. Furthermore, the bottom wall 1112 can have a first opening 11121, and at least a portion of the first protrusion 1211 can extend into the first opening 11121 along the first direction X. It can be understood that the second mounting portion 121 can have a displacement along the first direction X relative to the first mounting portion 111. The setting of the above-mentioned first opening 11121 can provide a larger displacement space for the second mounting portion 121 without additionally increasing the size of the first groove body 1111 along the first direction X. Combined with the above-mentioned abutment setting, the size of the first protrusion 1211 in the first direction X can be varied, and its larger part can be passed through the first opening 11121, and the smaller part can abut against the bottom wall 1112.

[0070] For the location of the first hook 12111 and the second hook 11111, see Figure 3 In some embodiments, along the first direction X, the first hook 12111 is located at the end of the first protrusion 1211 near the first mounting portion 111, and the second hook 11111 is located at the end of the groove surface defining the first slot 1111 near the second mounting portion 121. This arrangement can simplify the structure of the first protrusion 1211 and the first slot 1111, reduce manufacturing costs, and facilitate assembly and disassembly of the first protrusion 1211 and the first slot 1111. Furthermore, in other embodiments, only the first hook 12111 may be located at the end of the first protrusion 1211 near the first mounting portion 111, while the second hook 11111 is located in the middle of the groove surface defining the first slot 1111; or only the second hook 11111 may be located at the end of the groove surface defining the first slot 1111 near the second mounting portion 121, while the first hook 12111 is located in the middle of the first protrusion 1211.

[0071] Furthermore, in order to make the installation of the dining tray assembly 120 more stable, other installation structures can be provided. Figures 4 - 7, in some embodiments, one of the first mounting portion 111 and the second mounting portion 121 is further provided with a second protrusion 1113, and the other is provided with a second groove 1212. For the convenience of description, the following embodiments in which the first mounting portion 111 is provided with the second protrusion 1113 and the second mounting portion 121 is provided with the second groove 1212 will be taken as an example. The second protrusion 1113 extends into the second groove 1212 along the gravity direction Z, so that the first mounting portion 111 can abut against the second mounting portion 121 along the reverse direction of the gravity direction Z. It can be understood that along the gravity direction Z, one end of the wall surface defining the second groove 1212 may have an opening, and the second protrusion 1113 can extend into the second groove 1212 from the opening, and the other end opposite to the opening (which can be the wall surface opposite to the opening or the wall surface adjacent to the opening) can abut against the second protrusion 1113, thereby restricting the displacement of the dinner plate assembly 120 along the gravity direction Z. Combining the above-described embodiments of the first protrusion 1211 and the first groove 1111, for the abutting action of the second mounting portion 121 along the gravity direction Z, in some embodiments, only the abutting action along the gravity direction Z may be formed between the second protrusion 1113 and the second groove 1212, and no supporting action is formed between the first protrusion 1211 and the first groove 1111; in other embodiments, only the abutting action along the gravity direction Z may be formed between the first protrusion 1211 and the first groove 1111, and no supporting action is formed between the second protrusion 1113 and the second groove 1212.

[0072] To make the above abutting action along the gravity direction Z better, refer to Figures 4 - 7 , in some embodiments, along the gravity direction Z, the dimension of the second protrusion 1113 along the second direction Y and the dimension of the second groove 1212 along the second direction Y both gradually increase. The above setting makes the second protrusion 1113 and the second groove 1212 both trapezoidal when observed along the first direction X. Thus, during the process of the second protrusion 1113 extending into the second groove 1212 along the gravity direction Z, the second protrusion 1113 can gradually fit against the groove wall of the second groove 1212, so as to form an abutting action along the gravity direction Z and make the acting force relatively stable.

[0073] In addition, to facilitate controlling the telescopic movement of the first protrusion 1211 along the first direction X, refer to Figures 4 - 5In some embodiments, the second mounting portion 121 further includes a pressing member 1213, a locking seat 1214, an elastic member 1215, and a first connecting seat 1216. The first connecting seat 1216 has a second opening 12161. Along the first direction X, the second mounting portion 121 and the pressing member 1213 each have one end connected to the side of the locking seat 1214 close to the first mounting portion 111, and the other end extending through the second opening 12161. The elastic member 1215 also has one end abutting against the side of the locking seat 1214 facing away from the first mounting portion 111, and the other end abutting against the first connecting seat 1216. According to the above definition, the locking seat 1214 and the first connecting seat 1216 can have any suitable structural shape, and the elastic member 1215 can specifically be any one of a spring, rubber, and silicone. The second opening 12161 can be one or multiple. If there are multiple second openings 12161, the second mounting portion 121 and the pressing member 1213 can be respectively extended through different second openings 12161. It is understood that when the pressing member 1213 is subjected to a driving force in the first direction X, the elastic member 1215 is compressed, and the locking seat 1214, the second mounting portion 121, and the pressing member 1213 all move in the first direction X, causing the first hook 12111 and the second hook 11111 to disengage from each other, thereby facilitating separation of the dining tray assembly 120 and the seat assembly 110. After the driving force is released, the locking seat 1214, the second mounting portion 121, and the pressing member 1213 all move in the opposite direction of the first direction X to achieve reset. The locking seat 1214, the second mounting portion 121, and the pressing member 1213 can be integrally connected to increase connection strength and reduce manufacturing costs.

[0074] Further, in order to increase the connection strength between the second mounting portion 121 and the locking seat 1214, see Figure 5 In some embodiments, the locking seat 1214 further has a reinforcing protrusion 12141 on one side close to the first mounting portion 111 along the first direction X, and the reinforcing protrusion 12141 is connected to the second mounting portion 121. The reinforcing protrusion 12141 can have any suitable structural shape and is not limited here.

[0075] According to the use requirements, the baby carriage 100 can also be provided with a rotating structure so that the seat assembly 110 and the dining tray assembly 120 can both rotate, thereby achieving the folding effect of the seat assembly 110 and the dining tray assembly 120. Figures 6 - 9, in some embodiments, the seat assembly 110 further includes a first frame 112 and a second frame 113. Among them, the first frame 112 can be the push handle bracket of the stroller 100, and the second frame 113 can be the front foot frame of the stroller 100. The first frame 112 and the second frame 113 can be rotatably connected, and the relative rotation angle between the two can be determined according to requirements. In addition, in some embodiments, the first frame 112 includes a first pushing portion 1121, and the first mounting portion 111 includes a second pushing portion 1114. Thus, during the rotation of the first frame 112 relative to the second frame 113, the first pushing portion 1121 is configured to be able to push the second pushing portion 1114, so that both the first mounting portion 111 and the dinner plate assembly 120 rotate relative to the second frame 113. It can be understood that the above setting enables the first frame 112 and the second frame 113 to rotate relative to each other, and at the same time, it can also play a driving role on the dinner plate assembly 120. Specifically, when the first pushing portion 1121 pushes the second pushing portion 1114, the relative positions of the first mounting portion 111 and the second mounting portion 121 are fixed, so that the dinner plate assembly 120 can move accordingly, thereby achieving the effect of driving the dinner plate assembly 120 to rotate and fold up.

[0076] In addition, in some other embodiments, the process of the first frame 112 rotating relative to the second frame 113 can also correspond to the process when the frame of the stroller 100 is unfolded from the folded state to the normal use state. Thus, during this process, the process of the first pushing portion 1121 pushing the second pushing portion 1114 to drive the dinner plate assembly 120 to move can correspond to the process when the dinner plate assembly 120 is unfolded from the folded state to the normal use state.

[0077] For the specific settings of the first pushing portion 1121 and the second pushing portion 1114, see Figure 7In some embodiments, the first frame 112 further includes a third connecting seat 1122 having a third groove 11221. The outer wall of the third groove 11221 and the first mounting portion 111 both extend about a rotation axis L parallel to the first direction X. The first mounting portion 111 extends into the third groove 11221 (or may partially extend into the third groove 11221). The first pushing portion 1121 is connected to the connecting seat and is at least partially located in the third groove 11221. This structural arrangement allows the first mounting portion 111 to rotate within the third groove 11221, and both the first pushing portion 1121 and the second pushing portion 1114 can be located in the third groove 11221, thereby simplifying the rotation structure of the first mounting portion 111 and taking up less space. In addition, in some embodiments, the first pushing portion 1121 and the second pushing portion 1114 are both strip-shaped and extend radially along the rotation axis L. This arrangement allows the coaxially rotating first mounting portion 111 and the first frame 112 to form a pushing effect through the first pushing portion 1121 and the second pushing portion 1114 extending radially inward while rotating, making the pushing force easier to control and more stable.

[0078] For more details on the pushing action between the first pushing portion 1121 and the second pushing portion 1114, see Figures 6 - 9 In some embodiments, the first frame 112 is configured to rotate relative to the second frame 113 along a first circumferential direction about an axis parallel to the first direction X, and the first pushing portion 1121 can abut the second pushing portion 1114 in a direction away from the direction of gravity Z, so that the first mounting portion 111 and the tray assembly 120 both rotate in opposite directions relative to the second frame 113 along the first circumferential direction. This arrangement can make the folding movement of the first frame 112 and the tray assembly 120 more reasonable and help save space. In other embodiments, the first frame 112 and the tray assembly 120 can also both rotate along the first circumferential direction. More specifically, during the rotation of the first frame 112 relative to the second frame 113, the upper end surface of the first pushing portion 1121 can push the lower end surface of the second pushing portion 1114 radially away from the axis, thereby generating the aforementioned pushing effect.

[0079] In order to be able to fix or fold the dining tray assembly 120 in different states, the rotational pushing action between the first pushing portion 1121 and the second pushing portion 1114 can also be locked. Figure 7, in some embodiments, the seat assembly 110 further includes a pushing portion 114 configured to reciprocate in a first direction X so that the pushing portion 114 has a locking position and an unlocking position. Based on the definitions of the third connecting seat 1122 and the third groove 11221 in the above embodiments, correspondingly, the first mounting portion 111 has a fourth groove 1115. Thus, when the pushing portion 114 is in the locking position, the pushing portion 114 can extend into the third groove 11221 and the fourth groove 1115 to fix the relative positions among the first frame 112, the first mounting portion 111, and the dinner plate assembly 120. It can be understood that at this time, since the pushing portion 114 extends into both the third groove 11221 provided in the first frame 112 and the fourth groove 1115 provided in the first mounting portion 111, the first frame 112 and the first mounting portion 111 cannot rotate relative to each other. Therefore, when the pushing portion 114 is in the locking position, it can correspond to the state when the stroller 100 is in normal use or when the folding is completed, and at this time, the relative positions of the dinner plate assembly 120 and the seat assembly 110 need to be fixed. When the pushing portion 114 is in the unlocking position, the pushing portion 114 disengages from the third groove 11221 and extends into the fourth groove 1115 so that the first pushing portion 1121 can push the second pushing portion 1114. It can be understood that at this time, the pushing portion 114 no longer extends into both the third groove 11221 and the fourth groove 1115, so that the first frame 112 and the first mounting portion 111 can rotate relative to each other, enabling the first pushing portion 1121 to push the second pushing portion 1114. In addition, in some other embodiments, when the pushing portion 114 is in the unlocking position, the pushing portion 114 can also extend into the third groove 11221 and disengage from the fourth groove 1115, which can also achieve the effect of allowing the first frame 112 and the first mounting portion 111 to rotate relative to each other.

[0080] Further, in some embodiments, when the initial state is the normal use state of the stroller 100, a locking member is provided between the first frame 112 and the second frame 113, so that the first frame 112 and the second frame 113 cannot rotate relative to each other. If the stroller 100 is to be folded, the locking member can be disengaged from the first frame 112 and the second frame 113 (or one of the two frames) by pressing the unlocking button, so that the first frame 112 and the second frame 113 can rotate relative to each other; thereafter, based on the front foot support of the front foot of the stroller 100 and the rear foot support of the rear foot being respectively rotatably connected to the third connecting seat 1122 and the front foot support being provided with a pushing inclined surface, the front foot support rotates relative to the first frame 112 at this time (corresponding to the folding operation). At the same time, the pushing inclined surface pushes the pushing portion 114 along the first horizontal direction, so that the pushing portion 114 is switched from the locking position to the unlocking position; after the pushing portion 114 is in the unlocking position, by the relative rotation of the rear foot support and the first frame 112, the first frame 112 can be rotated relative to the first mounting portion 111 at the same time (corresponding to the folding operation), and then the first pushing portion 1121 pushes the second pushing portion 1114, that is, the folding of the dining plate assembly 120 is completed at the same time. The above settings make the folding operation process of each part of the stroller 100 simple, rapid and coherent.

[0081] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made under the application concept of the present application by using the content of the specification and drawings of the present application, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
