Description

Technical Field

[0001] This utility model relates to the technical field of handcarts, specifically to a handcart equipped with a seat-mounted rocker bed device. Background Technology

[0002] Strollers are widely used as convenient tools for daily infant care and outdoor outings. However, existing strollers have significant shortcomings in functional adaptability: Firstly, most strollers lack a rocking function, failing to meet the need for soothing rocking during rest. Even those strollers with integrated rocking functions have flawed rocking methods, relying primarily on manual pushing by adults. This requires continuous operation, is time-consuming and laborious, and the amplitude and frequency of the rocking are entirely controlled manually, resulting in poor stability and hindering a comfortable sleeping environment for infants. Secondly, strollers lack folding and storage convenience. Existing strollers with rocking functions have poor compatibility between the rocking mechanism and the main structure, requiring separate disassembly of the rocking component for folding, which is cumbersome. Furthermore, the overall size remains large after folding, taking up considerable space and making them inconvenient for home storage or carrying when out.

[0003] Therefore, there is an urgent need for a handcart that can automatically and stably rock, fold and store conveniently, and has intelligent adjustment functions to overcome the shortcomings of existing technologies. Utility Model Content

Detailed Implementation

[0035] The following are specific embodiments of the present invention described in conjunction with the accompanying drawings, further illustrating the technical solution of the present invention. However, the present invention is not limited to these embodiments. Specific details such as particular configurations and components are provided in the following description merely to aid in a comprehensive understanding of the embodiments of the present invention. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0036] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0037] like Figure 1-7 As shown, this embodiment provides a handcart equipped with a seat rocker bed device, which mainly includes a fixed bracket 1, a transverse plate 2, a transverse support 3, a drive motor 4, a front wheel support 7, a rear wheel support 8, a pusher frame 9, a canopy frame 10, a surround frame 11, and a folding control assembly 12; the fixed bracket 1 is the main support structure of the handcart, and two slide rails 101 are symmetrically arranged on its inner side. The slide rails 101 extend in the front-back direction to guide the movement of the transverse plate 2; an mounting rod 102 is fixed on the inner side of the slide rails 101, and the mounting rod 102 provides a mounting base for the drive motor 4.

[0038] The transverse sliding plate 2 is the core component of the support plate. Sliding sleeves 201 are detachably installed on its left and right sides. The sliding sleeves 201 are fitted onto the slide rail 101, allowing the transverse sliding plate 2 to move back and forth along the slide rail 101. Specifically, each side of the transverse sliding plate 2 has a side plate 204 perpendicular to the plate surface. The side plate 204 has mounting protrusions 205 spaced vertically at intervals. The sliding sleeve 201 is located between two mounting protrusions 205. The upper and lower sides of the sliding sleeve 201 have grooves 2011. The ends of the mounting protrusions 205 have fixed bearings 206, which can be engaged within the grooves 2011, enabling the sliding sleeve 201 to be detachably fixed to the transverse sliding plate 2.

[0039] A positioning frame 6 is provided at the lower rear end of the fixed bracket 1. A positioning plate 601 is vertically provided in the middle of the positioning frame 6. The positioning pin 103 at the rear end of the fixed bracket 1 can be inserted into the hole at the upper end of the positioning plate 601. The positioning pin and the hole cooperate to limit the displacement of the fixed bracket 1 and improve the overall stability. A connecting plate 602 is provided at both ends of the positioning frame 6. One end of the connecting plate 602 is hinged to the fixed bracket 1 and the other end is hinged to the rear wheel bracket 8 to realize the movable connection between the fixed bracket and the rear wheel bracket.

[0040] The drive motor 4 is fixed to the mounting rod 102, and its output shaft is vertically upward and connected to the turntable 5. A sliding bearing 501 is located near the edge of the upper surface of the turntable 5, and the sliding bearing 501 is embedded in the long groove 203 at the bottom of the transverse plate 2. When the drive motor 4 starts, the output shaft drives the turntable 5 to rotate, and the sliding bearing 501 moves in a circular motion with the turntable 5. Because the sliding bearing 501 is restricted by the long groove 203 (it can only move along the direction of the long groove), the force of the circular motion is converted into a force that pushes the transverse plate 2 to move back and forth along the slide rail 101, thereby driving the transverse support 3 and the upper seat plate to achieve stable rocking. The rocking frequency can be changed by adjusting the speed of the drive motor 4.

[0041] The folding function of the trolley is achieved through the folding control component 12, which includes a first folding piece 1201, a second folding piece 1202, a third folding piece 1203, and a fourth folding piece 1204 that are sequentially fastened from the inside out, and has a first gear 1205, a second gear 1206, and a rotating wheel 1207 inside. The two ends of the enclosure 11 are fixedly connected to the first folding member 1201. The front wheel bracket 7 is fixedly connected to one end of the second folding member 1202. The rear wheel bracket 8 is hinged to the other end of the second folding member 1202. The two ends of the canopy frame 10 are fixedly connected to the third folding member 1203. The two ends of the push frame 9 are fixedly connected to the fourth folding member 1204. A spring (not shown in the figure) is provided between the first gear 1205 and the first folding member 1201. The spring force pushes the first gear 1205 to extend part of the first gear 1205 into the second folding member 1202, so that it can simultaneously mesh with the tooth grooves inside the first folding member 1201 and the second folding member 1202 (locked state). When the button 901 at the top of the push frame 9 is pressed, the button 901 pulls the pull rope (not shown in the figure) inside the push frame 9. The other end of the pull rope is connected to the pull rope fixing groove 12071 of the rotating wheel 1207, which drives the rotating wheel 1207 to rotate. One end of the second gear 1206 abuts against the first gear 1205, and the other end is provided with a first inclined block 12061; the corresponding surface of the rotating wheel 1207 is provided with a second inclined block 12072, and the inclined surfaces of the two inclined blocks are in contact. When the rotating wheel 1207 rotates, the second inclined block 12072 pushes the first inclined block 12061, causing the second gear 1206 to move towards the first gear 1205, thereby pushing the first gear 1205 to compress the spring and disengage the second folding member 1202 (at this time, the first gear 1205 only meshes with the first folding member 1201, and the second gear 1206 only meshes with the second folding member 1202), releasing the lock, and each folding member can rotate relative to each other, realizing the folding of the handcart.

[0042] The fourth folding component 1204 has a chip circuit board 1208 on its outer side, and a touch screen 1209 on its outer side; the chip circuit board 1208 is electrically connected to the drive motor 4 and the touch screen 1209. The user can input commands (such as shaking frequency and duration) through the touch screen 1209, and the chip circuit board 1208 controls the drive motor 4 to run after receiving the commands, realizing intelligent adjustment.

[0043] The stroller in this embodiment, through the above-described structure, achieves functions such as automatic and stable rocking, convenient folding, and intelligent adjustment, effectively solving the defects of the prior art and is suitable for outdoor travel and home rest scenarios for infants and young children.
