Description

TECHNICAL FIELD

[0001] The present application relates to the field of child carriers, and in particular to a child carrier with a conversion device support structure. BACKGROUND

[0002] Child carriers, such as strollers, are carriers that are used to carry children and are extremely convenient.

[0003] In the related art, child carriers are provided with baskets so that the child carriers can be carried. Some child carriers are provided with front aprons, and children can hold the front aprons when they sit on the child carriers. Some child carriers are provided with both baskets and front aprons, but the structures are complex and the use is cumbersome. SUMMARY

[0004] The present application aims to at least solve one of the technical problems in the prior art. To this end, the present application proposes a child carrier that can meet the needs while reducing weight and reducing the complexity of the appearance.

[0005] The child carrier with a conversion device support structure according to the embodiments of the present application has a frame, a seat part, a handrail assembly, and a handle assembly. The frame is fixedly provided with mounting seats for connecting the handrail assembly or the handle assembly on the left and right sides above the seat part. The handle assembly is provided with first connecting seats at both ends for connecting the mounting seats, and the handrail assembly is provided with second connecting seats at both ends for connecting the mounting seats. The first connecting seats and the second connecting seats are selectively detachably connected to the two mounting seats to realize the function of connecting a child carrying mechanism or the function of a handrail.

[0006] The first connecting seat includes an upper connecting seat and a lower connecting seat. The lower connecting seat is detachably fixedly connected to the mounting seat, and the upper end of the lower connecting seat is provided with a receiving part. The upper end of the upper connecting seat is suitable for connecting the connecting end of the child carrying mechanism, and the lower end of the upper connecting seat is provided with a penetrating part. The penetrating part is sleeved with the receiving part along the left-right direction and can move left and right relative to the receiving part, so as to adjust the distance between the two penetrating parts and adapt to child carrying mechanisms of different sizes.

[0007] One of the upper connecting seat and the lower connecting seat is provided with a lock tongue, and the other is provided with at least two lock holes. The at least two lock holes are arranged along the left-right direction, and the lock tongue is selectively inserted into the lock hole to fix the relative position of the upper connecting seat and the lower connecting seat.

[0008] The embodiments of the present application are detachably matched with the handle assembly and the handrail assembly through the mounting seats, and the child carrier with a conversion device support structure is switched between the handle assembly and the handrail assembly for installation. The child carrier with a conversion device support structure is switched between the function of connecting a child carrying mechanism and the function of a handrail according to customer needs, so that the child carrier with a conversion device support structure has multiple application functions and is convenient for customers to use.

[0009] Meanwhile, when the customer lifts the child carrier with the conversion device support structure through the handle assembly, the child carrier with the conversion device support structure will generally change angle due to the action of the center of gravity, the front end deflects upward and the rear end deflects downward, at this time the child in the child carrier can generally be in a backward-leaning or even lying position, and the demand for the handle assembly is small. When the child carrier is put down, the child can normally sit on the seat part, at this time the handle assembly can be used to block in front of the child, facilitating the child to hold hands, reducing the probability of the child rolling from the front, at this time the demand for the handle assembly is small. Therefore, the handle assembly and the armrest assembly are arranged to be switchably mounted on the mounting seat, one of which can be selected for installation according to actual needs. The mounting seat does not need to simultaneously mount the handle assembly and the armrest assembly, which reduces the redundancy of the appearance of the child carrier, and is beneficial to reduce the weight.

[0010] In some embodiments, the lock hole is formed at the top of the lock block, and the lock tongue is arranged on the upper connecting seat, and the bottom of the lock tongue extends into the lock cover. In this way, the structure is compact, the various parts are hidden, and the appearance is improved.

[0011] In some embodiments, the lock tongue is movably arranged in the upper connecting seat, and the first reset elastic member is further arranged in the upper connecting seat, and the first reset elastic member is used to drive the lock tongue to extend downward into the lock cover. In this way, the lock tongue is driven to reciprocate by the first reset elastic member, and the lock tongue can automatically return to the initial position after being separated from the lock hole, facilitating the optional insertion of the lock tongue into the lock hole.

[0012] In some embodiments, the top of the lower connecting seat is further provided with two grooves located on the front and rear sides of the supporting sleeve part; the bottom of the lower connecting seat forms two stop tables located on the front and rear sides of the penetrating sleeve part, and the two stop tables extend into the corresponding grooves; during the movement of the penetrating sleeve part relative to the supporting sleeve part to adjust the distance between the two penetrating sleeve parts, the two stop tables move left and right within the range defined by the grooves. In this way, on the one hand, the movement of the upper connecting seat in the front-rear direction is constrained, and on the other hand, the connection strength between the upper connecting seat and the lower connecting seat is further improved, and the reliability of the connection between the two is improved.

[0013] In some embodiments, the bottom of the lower connecting base is provided with a U-shaped cutout, and the bottom of the lower connecting base is formed with an elastic plate connected to the lower connecting base on one side. The elastic plate protrudes away from the bottom of the lower connecting base to form a stop protrusion. The stop protrusion is used to extend into the corresponding groove. In this way, on the one hand, the process of processing the elastic plate is simple, and the manufacturing cost is low. On the other hand, the end of the stop protrusion in contact with the limiting rotating table in the groove is in surface contact, thereby increasing the friction between the stop protrusion and the groove and further improving the limiting effect between the stop protrusion and the groove. In some embodiments, the elastic plate is a concave plate, and the concave direction of the elastic plate is opposite to the sleeve connection direction of the upper connecting base. In this way, when the upper connecting base moves relative to the lower connecting base, the curved surface of the elastic plate gently contacts the lower connecting base, and the lower connecting base slowly compresses the elastic plate to retract into the cutout, further avoiding accidental breakage of the elastic plate.

[0014] In some embodiments, the groove is rectangular, and the left and right sidewalls of the groove are used to limit the left and right movement range of the stop table. In this way, by limiting the movement of the stop table through the left and right sidewalls, the stop table moves within a predetermined range, thereby avoiding interference with the optional insertion of the lock tongue into the lock hole.

[0015] In some embodiments, the left side or the right side of the mounting base is provided with a plug-in table, and the upper and lower sides of the plug-in table are respectively provided with plug-in plates. The first connecting base and the second connecting base are each provided with a mounting slot, the rear end of the mounting slot is open to one side of the mounting base, and the top and bottom of the mounting slot are respectively formed with plug-in slots. The plug-in table is fitted in the mounting slot, and the upper and lower plug-in plates of the plug-in table are respectively inserted into the upper and lower plug-in slots. In this way, on the one hand, the mounting base and the lower connecting base are detachably fitted, and on the other hand, the connection reliability between the upper plug-in plate and the upper plug-in slot and between the lower plug-in plate and the lower plug-in slot is increased.

[0016] In some embodiments, the plug-in table is provided with a clamping hole. The first connecting base and the second connecting base are each provided with a first matching hole and a second matching hole. The first matching hole is located in the mounting slot, and the second matching hole is located on the front side of the mounting slot. The first connecting base and the second connecting base are each provided with a control assembly. The control assembly includes an operating member, which is swingably arranged and provided with a pressing portion and a clamping block. The pressing portion is located at the second matching hole, and the clamping block extends from the first matching hole into the mounting slot and is used to insert into the clamping hole. The control assembly further includes a second elastic member connected to the operating member. In this way, by pressing the pressing portion, the spring is in a compressed state, and the clamping block is separated from the clamping hole. By releasing the pressing portion, the spring is in an initial state, and the clamping block is inserted into the clamping hole. This setting is convenient for the disassembly of the lower connecting base and the mounting base.

[0017] In some embodiments, the frame comprises a side support rod, the side support rod is U-shaped, a part of the side support rod is located on the left and right sides of the seat plate and a part of the side support rod is located behind the seat plate, and two ends of the side support rod are connected with the mounting seat. In this way, the child can learn to walk with the help of the side support rod, and the application function of the child carrier is further increased.

[0052] As Figures 1-3 shown, Figure 1 A structural schematic diagram of a child carrier 100 with a conversion device support structure according to an embodiment of the present application is shown, Figure 2 A structural schematic diagram of a handrail assembly 50 according to an embodiment of the present application is shown. Figure 3 A structural schematic diagram of a handle assembly 40 according to an embodiment of the present application is shown. In Figure 1 An X, Y and Z axis coordinate system is established in the

[0053] A child carrier 100 with a conversion device support structure according to an embodiment of the present application includes a frame 10, a seat portion 20, a handrail assembly 50 and a handle assembly 40.

[0054] The two installation seats 30 are respectively arranged on the left and right sides above the seat part 20 and are respectively fixedly provided with a mounting seat 30 for connecting a handrail assembly 50 or a handle assembly 40; the two ends of the handle assembly 40 are correspondingly provided with a first connecting seat 401 for connecting the mounting seat 30, and the two ends of the handrail assembly 50 are correspondingly provided with a second connecting seat 51 for connecting the mounting seat 30, and the first connecting seat 401 and the second connecting seat 51 are detachably connected to the two mounting seats 30, so as to realize the connection of the child-carrying mechanism function or the handrail function.

[0055] The first connecting seat 401 comprises an upper connecting seat 41 and a lower connecting seat 42. The lower connecting seat 42 is detachably fixedly connected to the mounting seat 30, and the upper end of the lower connecting seat 42 is provided with a bearing sleeve part 424. The upper end of the upper connecting seat 41 is suitable for connecting the connecting end of the child-carrying mechanism, and the lower end of the upper connecting seat 41 is provided with a through sleeve part 411 along the left-right direction, the through sleeve part 411 is sleeved with the bearing sleeve part 424 along the left-right direction and can move left and right relative to the bearing sleeve part 424, so as to adjust the distance between the two through sleeve parts 411 and adapt to different sizes of the child-carrying mechanism.

[0056] One of the upper connecting seat 41 and the lower connecting seat 42 is provided with a lock tongue 417, and the other is provided with at least two lock holes 421, the at least two lock holes 421 are arranged along the left-right direction, and the lock tongue 417 is inserted into the lock hole 421, so as to fix the relative position of the upper connecting seat 41 and the lower connecting seat 42.

[0057] It should be noted that the frame 10 here is the frame 10 of the child stroller, and the frame 10 can be foldable, and the frame 10 can also be fixed. The frame 10 comprises oppositely arranged left and right frame bodies 11 and 12 and a connecting frame body 13 connecting the left and right frame bodies 11 and 12, and the connecting frame body 13 is located at the rear side of the left and right frame bodies to form a containing space for placing the seat part 20. The specific structure of the left and right frame bodies 11 and 12, the connecting frame body 13 and the seat part 20 is not limited in the embodiment.

[0058] The two installation seats 30 are respectively arranged on the left and right sides above the seat part 20 and are respectively fixedly provided with a mounting seat 30 for connecting a handrail assembly 50 or a handle assembly 40; the two ends of the handle assembly 40 are correspondingly provided with a first connecting seat 401 for connecting the mounting seat 30, and the two ends of the handrail assembly 50 are correspondingly provided with a second connecting seat 51 for connecting the mounting seat 30, and the first connecting seat 401 and the second connecting seat 51 are detachably connected to the two mounting seats 30, so as to realize the connection of the child-carrying mechanism function or the handrail function.

[0059] The two ends of the handrail assembly 50 are provided with second connecting seats 51, which are detachably connected with the mounting seat 30, so that the handrail assembly 50 can be quickly and conveniently installed and detached. For example, the second connecting seat 51 and the mounting seat 30 are connected by a locking member, which is fixedly connected in the locked state and is separated in the unlocked state. Alternatively, the second connecting seat 51 and the mounting seat 30 are connected by a buckle and a clamping groove. Alternatively, the second connecting seat 51 and the mounting seat 30 are connected by a threaded connection, etc. The handrail assembly 50 is arranged to enable children to hold it, thereby protecting the safety of children, and at this time the child carrier 100 has a second application function: a handrail function.

[0060] The child carrier 100 with the conversion device support structure is detachably connected with the handle assembly 40 and the handrail assembly 50 through the mounting seat 30, and then the child carrier 100 with the conversion device support structure is switched between the handle assembly 40 and the handrail assembly 50 for installation, so that the child carrier 100 with the conversion device support structure is switched between the child carrying mechanism function and the handrail function according to the customer's needs, thereby the child carrier 100 with the conversion device support structure has multiple application functions, which is convenient for customers to use.

[0061] At the same time, when the customer lifts the child carrier 100 with the conversion device support structure through the handle assembly 40, the child carrier 100 with the conversion device support structure will generally change the angle due to the action of the center of gravity, the front end is deflected upward and the rear end is deflected downward, at this time the child in the child carrier 100 can generally assume a backward-leaning or even lying posture, and the demand for the handrail assembly 50 is small. When the child carrier 100 is put down, the child can normally sit on the seat part 20, at this time the handrail assembly 50 can be used to block in front of the child, which is convenient for the child to hold, and reduces the probability of the child falling from the front, at this time the demand for the handle assembly 40 is small. Therefore, the handle assembly 40 and the handrail assembly 50 are arranged to be switchably installed on the mounting seat 30, and one of them can be selected for installation according to the actual needs. The mounting seat 30 does not need to simultaneously install the handle assembly 40 and the handrail assembly 50, which reduces the redundancy of the appearance of the child carrier 100, and is beneficial to reduce the weight.

[0062] Specifically, the bottom of the frame 10 is provided with walking wheels, for example, three or four or even more walking wheels can be installed at the bottom of the frame 10. The arrangement of the walking wheels enables the child carrier 100 to be pushed to walk, which is convenient for moving with the child.

[0063] For example, the handle assembly 40 and the handrail assembly 50 are arranged to be switchably installed on the mounting seat 30, and one of them can be selected for installation according to the actual needs. Figure 3As shown, when the handle assembly 40 is installed, the handle assembly 40 further comprises a handle part 402, two ends of the handle part 402 are connected to two first connecting seats 401 respectively. The first connecting seat 401 comprises: a lower connecting seat 42, which is detachably connected to the mounting seat 30; and an upper connecting seat 41, which is adjustably mounted on the lower connecting seat 42 in the left-right direction, and the two ends of the handle part 402 are connected to the upper connecting seats 41 of the two first connecting seats 401. In this way, by adjusting the distance between the two first connecting seats 401, different sizes of seat parts 20 can be adapted.

[0064] It should be noted that, as Figure 3 shown, the handle part 402 can be a flexible member, for example, the handle part 402 is a belt. The handle part 402 can be a rigid member, for example, the handle part 402 is a U-shaped steel material, or a C-shaped steel material. The two lower connecting seats 42 are connected to the left and right frame bodies respectively, and the distance between them does not change. The upper connecting seat 41 is adjustably mounted on the lower connecting seat 42 in the left-right direction, that is, the upper connecting seat 41 on the left frame body 11 can be close to or away from the upper connecting seat 41 on the right frame body 12, and the upper connecting seat 41 on the right frame body 12 can be close to or away from the upper connecting seat 41 on the left frame body 11, so that the distance between the two upper connecting seats 41 can be adjusted, and the distance between the two first connecting seats 401 can be adjusted.

[0065] As Figures 4-8 shown, the lower end of the upper connecting seat 41 on the left frame body 11 is provided with a penetrating sleeve part 411, which is U-shaped, and the cover opening of the penetrating sleeve part 411 faces away from the right frame body 12. Correspondingly, the lower connecting seat 42 on the left frame body 11 is provided with a receiving sleeve part 424, which is provided on the upper end of the lower connecting seat 42 and on the side facing the right frame body 12, and the receiving sleeve part 424 is embedded and inserted with the penetrating sleeve part 411. By adjusting the depth of the receiving sleeve part 424 embedded and inserted in the penetrating sleeve part 411, the upper connecting seat 41 can be adjusted in the left-right direction relative to the lower connecting seat 42. In some schemes, the cover opening of the penetrating sleeve part 411 faces the right frame body 12, and correspondingly, the receiving sleeve part 424 is provided on the upper end of the lower connecting seat 42 and on the side facing away from the right frame body 12.

[0066] As Figure 8 shown, the upper end of the lower connecting seat 42 and the surface facing the right frame body 12 are recessed with a U-shaped notch 425, and the receiving sleeve part 424 is protruded from the bottom of the U-shaped notch 425. A U-shaped groove is formed between the side wall of the receiving sleeve part 424 and the inner side wall of the U-shaped notch 425, and the penetrating sleeve part 411 is sleeved in the U-shaped groove. In this way, the upper connecting seat 41 and the lower connecting seat 42 can be aligned in the up-down direction, thereby avoiding the occupation of the space between the left frame body 11 and the right frame body 12 by the upper connecting seat 41, which is beneficial to the placement of the seat part 20 of large size in the space.

[0067] One of the upper connecting seat 41 and the lower connecting seat 42 is provided with a lock tongue 417, and the other is provided with a plurality of lock holes 421 arranged along the left-right direction, and the lock tongue 417 is selectively inserted into the lock hole 421. In this way, the movement of the upper connecting seat 41 relative to the lower connecting seat 42 in the left-right direction can be limited to firmly fix the two.

[0068] In some embodiments, a plurality of lock holes 421 are arranged on the side wall of the sleeve part 411 of the upper connecting seat 41 along the movement direction (left-right direction) of the upper connecting seat 41. A matching hole cooperating with the lock hole 421 is arranged on the side wall of the U-shaped notch 425 of the lower connecting seat 42. The lock tongue 417 is selectively inserted into the lock hole 421 through the matching hole. In this way, the structure is compact, the parts are hidden, and the appearance is improved.

[0069] In some embodiments, the lock hole 421 is formed at the top of the sleeve part 424, and the lock tongue 417 is arranged on the upper connecting seat 41, and the bottom of the lock tongue 417 extends into the sleeve part 411.

[0070] Specifically, as shown in Figures 5-8 The lock tongue 417 is arranged in the sleeve part 411 of the upper connecting seat 41, and the opening 412 capable of passing through the lock tongue 417 is arranged at the connection between the upper connecting seat 41 and the sleeve part 411, and the lock tongue 417 reciprocates along the direction from the upper connecting seat 41 to the lower connecting seat 42, so that the bottom of the lock tongue 417 extends into the sleeve part 411. A plurality of lock holes 421 are arranged on the top of the sleeve part 424 facing the upper connecting seat 41 along the movement direction (left-right direction) of the upper connecting seat 41. The lock tongue 417 is selectively inserted into the lock hole 421. In this way, the structure is compact, the parts are hidden, and the appearance is improved.

[0071] Further, the lock tongue 417 is movably arranged in the upper connecting seat 41, and the first reset elastic member 415 is further arranged in the upper connecting seat 41, and the first reset elastic member 415 is used to drive the lock tongue 417 to extend downward into the sleeve part 411.

[0072] Specifically, the lock tongue 417 reciprocates through the first reset elastic member 415, and the first reset elastic member 415 is a spring. As Figure 5As shown, the upper connecting base 41 has oppositely arranged side plates 414, and a support plate 413 is arranged inside the upper connecting base 41. One end of the support plate 413 is connected with one side plate 414, and the other end of the support plate 413 is exposed to the other side plate 414. The exposed part of the support plate 413 in the upper connecting base 41 is driven to swing up and down. One end of a spring is connected with the middle part of the support plate 413, and the other end of the spring is connected with the lock tongue 417. The exposed part of the support plate 413 in the upper connecting base 41 is driven to move downward, and then the lock tongue 417 extends into the sleeve part 411, and the bottom of the lock tongue 417 is inserted into the lock hole 421. The exposed part of the support plate 413 in the upper connecting base 41 is driven to move upward, and then the bottom of the lock tongue 417 is separated from the lock hole 421. In this way, the lock tongue 417 is driven to reciprocate by the first reset elastic member 415, and the lock tongue 417 can automatically return to the initial position after being separated from the lock hole 421, so that the lock tongue 417 can be selectively inserted into the lock hole 421.

[0073] In some embodiments, the top of the lower connecting base 42 is further provided with two grooves 422 located on the front and back of the sleeve part 424. The bottom of the upper connecting base 41 forms two stop tables 416 located on the front and back of the sleeve part 411, and the two stop tables 416 respectively extend into the corresponding grooves 422. During the movement of the sleeve part 411 relative to the sleeve part 424 to adjust the distance between the two sleeve parts 411, the two stop tables 416 move left and right within the range defined by the grooves 422.

[0074] Specifically, the top of the lower connecting base 42 is further provided with two grooves 422 located on the front and back of the sleeve part 424, and a rotation limiting table 423 is protruded on the middle of the bottom of the groove 422. The bottom of the upper connecting base 41 forms two stop tables 416 located on the front and back of the sleeve part 411, and the two stop tables 416 respectively extend into the corresponding grooves 422, and then the two stop tables 416 are rested on the two rotation limiting tables 423. During the movement of the sleeve part 411 relative to the sleeve part 424 to adjust the distance between the two sleeve parts 411, the two stop tables 416 move left and right within the range defined by the grooves 422. In this way, on the one hand, the movement of the upper connecting base 41 in the front and back directions is restricted, and on the other hand, the connection strength between the upper connecting base 41 and the lower connecting base 42 is further enhanced, and the reliability of the connection between the two is improved.

[0075] Further, the bottom of the upper connecting base 41 is provided with a U-shaped cut hole 418, so that an elastic plate 4161 connected with the upper connecting base 41 is formed on the bottom of the upper connecting base 41. The elastic plate 4161 protrudes in the direction away from the bottom of the upper connecting base 41 to form a stop protrusion 4162, which is used to extend into the corresponding groove 422.

[0076] Specifically, as shown inFigures 5-8 As shown, the bottom of the upper connecting base 41 is provided with a U-shaped cutout 418 to form the elastic plate 4161 connected with the upper connecting base 41. Thus, when the cutout 418 is processed, the elastic plate 4161 is formed. In this way, the process of processing the elastic plate 4161 is simple, and the manufacturing cost is low. The elastic plate 4161 protrudes in a direction away from the bottom of the upper connecting base 41 to form a stop protrusion 4162, and the end of the stop protrusion 4162 in contact with the limiting rotating table 423 in the groove 422 is in surface contact, thereby increasing the friction between the stop protrusion 4162 and the groove 422 and further improving the limiting action between the stop protrusion 4162 and the groove 422.

[0077] Furthermore, the elastic plate 4161 is a concave plate, and the concave direction of the elastic plate 4161 is opposite to the sleeving direction of the sleeve part 411 of the upper connecting base 41. In this way, when the upper connecting base 41 moves relative to the lower connecting base 42, the elastic plate 4161 does not rigidly collide with the lower connecting base 42, the curved surface of the elastic plate 4161 gently contacts the lower connecting base 42, the lower connecting base 42 slowly compresses the elastic plate 4161 to retract into the cutout 418, and the accidental breakage of the elastic plate 4161 is avoided. The top of the lower connecting base 42 is concave to form a groove 422, and a limiting rotating table 423 is formed at the middle position of the groove 422. In this way, the area of the lower connecting base 42 abutting against the elastic plate 4161 can be reduced, and the compression time of the lower connecting base 42 on the elastic plate 4161 is shortened, thereby avoiding the accidental breakage of the elastic plate 4161.

[0078] In addition, the groove 422 is rectangular, and the left and right sidewalls of the groove 422 are used to limit the movement range of the stop table 416 to the left and right. The groove 422 includes oppositely arranged left and right sidewalls and oppositely arranged front and rear sidewalls, the width of the stop table 416 is equal to the distance between the front and rear sidewalls, and the length of the stop table 416 is less than the distance between the left and right sidewalls. The stop table 416 is located in the groove 422, the front and rear sidewalls form a sliding groove, the stop table 416 slides along the sliding groove, and the left and right sidewalls limit the sliding range of the stop table 416. In this way, the movement of the stop table 416 is limited by the left and right sidewalls, so that the stop table 416 moves within a predetermined range, and the stop table 416 does not interfere with the optional insertion of the lock tongue 417 into the lock hole 421.

[0079] In some embodiments, the left side or the right side of the mounting seat 30 is provided with an insertion table 32, and the upper and lower sides of the insertion table 32 are respectively provided with insertion plates (33, 34). The first connecting base 401 and the second connecting base 51 are each provided with a mounting groove, the rear end of the mounting groove is open to one side of the mounting seat 30, and the top and bottom of the mounting groove are respectively formed with insertion grooves (428, 429). The insertion table 32 is fitted in the mounting groove, and the insertion plates (33, 34) on the upper and lower sides of the insertion table 32 are respectively inserted into the upper and lower insertion grooves (428, 429).

[0080] It should be noted that the detachable cooperation between the mounting seat 30 and the first connecting seat 401 is the detachable cooperation between the mounting seat 30 and the lower connecting seat 42 of the first connecting seat 401. The detachable cooperation between the mounting seat 30 and the second connecting seat 51 is the same as the detachable cooperation between the mounting seat 30 and the lower connecting seat 42. Therefore, the detachable cooperation between the mounting seat 30 and the lower connecting seat 42 is exemplified, and the detachable cooperation between the mounting seat 30 and the second connecting seat 51 is not described again.

[0081] In specific embodiments, as shown in Figures 9-13 The mounting seat 30 is substantially a plate-shaped U. The mounting seat 30 includes a mounting seat body 31 and a plug station 32 connected to the mounting seat body 31. If the mounting seat 30 is located on the left frame body 12, the plug station 32 is connected to the surface of the mounting seat body 31 facing the right frame body 11. In this way, the connection between the plug station 32 and the first mounting groove 427 can be shielded, which is beneficial to improve the appearance. The plug station 32 forms an upper plug plate 33 vertically upward from the upper side thereof, and the plug station 32 forms a lower plug plate 34 vertically downward from the lower side thereof, as shown in Figure 13 Correspondingly, the first mounting groove 427 is recessed on the surface of the first connecting seat 401 located on the left frame body 11 facing the right frame body 12, the first mounting groove 427 extends in the front-rear direction, and the rear end side of the first mounting groove 427 is open, as shown in Figure 9 The top of the first mounting groove 427 forms an upper plug groove 428 cooperating with the upper plug plate 33, and the bottom of the first mounting groove 427 forms a lower plug groove 429 cooperating with the lower plug plate 34. The mounting seat 30 and the first mounting groove 427 are embedded and inserted, as shown in Figure 12 The plug station 32 is inserted into the first mounting groove 427, the upper plug plate 33 of the plug station 32 cooperates with the upper plug groove 428 of the first mounting groove 427, and the lower plug plate 34 of the plug station 32 cooperates with the lower plug groove 429 of the first mounting groove 427. In this way, on the one hand, the detachable cooperation between the mounting seat 30 and the lower connecting seat 42 is realized, and on the other hand, the connection reliability between the two is increased through the cooperation between the upper plug plate 33 and the upper plug groove 428 and the cooperation between the lower plug plate 34 and the lower plug groove 429.

[0082] It should be noted that if the mounting seat 30 is located on the right frame body 11, the plug station 32 is connected to the surface of the mounting seat body 31 facing the left frame body 12.

[0083] Further, the plug-in station 32 is provided with a clamping hole 35. The first connecting seat 401 and the second connecting seat 51 are both provided with a first matching hole 4271 and a second matching hole 426. The first matching hole 4271 is located in the first mounting groove 427 (the second mounting groove), and the first matching hole 4271 matches the clamping hole 35. The second matching hole 426 is located at the front side of the first mounting groove 427 (the second mounting groove). The first connecting seat 401 and the second connecting seat 51 are both provided with a control assembly 62. The control assembly 62 comprises an operating piece 621. The operating piece 621 is swingably arranged. The operating piece 621 is provided with a pressing portion 623 and a clamping block 622. The pressing portion 623 is located at the second matching hole 426. The clamping block 622 extends from the first matching hole 4271 into the first mounting groove 427, and is used for being inserted into the clamping hole 35.

[0084] In specific embodiments, as shown in Figures 8-13 If the mounting seat 30 is located on the left frame body 12, the first connecting seat 401 is provided with a first matching hole 4271. The first matching hole 4271 is located at the bottom of the first mounting groove 427. The first matching hole 4271 matches the clamping hole 35. The second matching hole 426 is located at the front side of the first mounting groove 427, and the second matching hole 426 communicates with the first mounting groove 427.

[0085] As shown in Figure 8 The control assembly 62 comprises an operating piece 621. One end of the operating piece 621 is a pressing portion 623. The other end of the operating piece 621 is a clamping block 622. The control assembly 62 is pivoted in the second matching hole 426. That is, the middle part of the operating piece 621 is provided with a pivot 61. The operating piece 621 can swing in the left-right direction. The plug-in station 32 is provided with a clamping hole 35 which matches the clamping block 622. After the mounting seat 30 on the left frame body 12 is embedded and matched with the first mounting groove 427, the clamping hole 35 on the plug-in station 32 matches the first matching hole 4271. The pressing portion 623 is pressed to make the clamping block 622 be inserted into the clamping hole 35. In this way, on the one hand, the movement of the lower connecting seat 42 of the first connecting seat 401 in the front-rear direction is restricted. On the other hand, the connection strength between the lower connecting seat 42 and the mounting seat 30 is further improved, and the connection reliability is improved.

[0086] Further, the pressing portion 623 of the operating piece 621 is made to rebound by a second elastic member 63. The second elastic member 63 is a spring. One end of the spring abuts against the pressing portion 623. The other end of the spring is connected to the body of the lower connecting seat 42. When the pressing portion 623 is pressed, the spring is in a compressed state, and the clamping block 622 is separated from the clamping hole 35. When the pressing portion 623 is released, the spring is in an initial state, and the clamping block 622 is inserted into the clamping hole 35. In this way, the operation is convenient, and the disassembly of the lower connecting seat 42 and the mounting seat 30 is facilitated.

[0087] In some embodiments, the frame 10 comprises side handrails 14, which are U-shaped, and the partial segments of the side handrails 14 are located on the left and right sides of the seat part 20 and the partial segments of the side handrails 14 are located behind the seat part 20, and the two ends of the side handrails 14 are connected to the mounting seats 30. In this way, the child can learn to walk with the help of the side handrails 14, further increasing the application function of the child carrier 100.
