Description

Technical Field

[0001] This invention relates to the field of stroller technology, and more specifically to a stroller that is easy for the elderly to use. Background Technology

[0002] Currently, for parents with infants and toddlers, strollers are a useful tool for assisting in the care of their children when taking them out. They provide a vehicle for sitting or lying down, allowing parents or grandparents to push the stroller and avoid the burden of carrying or holding the child. This makes it easier to take the child out for outings, walks, shopping, and other outdoor activities, and is indeed one of the infant and toddler products that enhances parent-child interaction.

[0003] However, with the increasingly fast pace of life, some parents need to devote more time and energy to work, so infants and young children at home need to be cared for by their grandparents. However, the existing strollers are becoming more and more complex in structure, and the operation of complex functions is a burden for the elderly. Moreover, if the elderly fail to react in time when the stroller is involved in a collision, the stroller may quickly move in any direction due to the impact, and a secondary collision may occur, posing a safety risk.

[0004] Therefore, it is necessary to propose a stroller that is easy for the elderly to use in order to solve the above problems. Summary of the Invention

[0048] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0049] This application provides a stroller that is easy for the elderly to use, which can solve the problem in related technologies that strollers may move rapidly in any direction after being hit, and secondary collisions may occur, posing a safety risk.

[0050] like Figure 1-5As shown, a stroller designed for elderly users includes: a main body 1, an angle adjustment mechanism 2, a first braking mechanism 3, a second braking mechanism 4, a lifting seat 5, a safety belt device 6, and a control device. The main body 1 is equipped with a base frame 101, a push handle 102, a baby seat 103, a positioning frame 104, and a first fixing plate 106. The push handle 102 is fixedly mounted on the base frame 101. The positioning frame 104 is mounted on the base frame 101 via two symmetrically arranged angle adjustment mechanisms 2. The baby seat 103 is fixedly installed inside the positioning frame 104, and a safety belt device 6 is installed on the baby seat 103. One end of the first fixing plate 106 is fixedly mounted on the base frame 101. The lifting seat 5 is fixedly mounted on the other end of the first fixing plate 106. Two front wheels are symmetrically mounted on the bottom of the base frame 101, and two rear wheels are symmetrically rotated and mounted on the bottom of the lifting seat 5. The first braking mechanism 3 and the second braking mechanism 4 are both mounted on the base frame 101 and are used to brake the front and rear wheels. The control device is used to control the operation of the entire stroller except for itself.

[0051] Specifically, such as Figure 3 As shown, in order to make the disassembly of the present invention more convenient, the main body 1 is also provided with a second fixing plate 105. One end of the second fixing plate 105 is horizontally fixedly installed on the base frame 101, and the other end of the second fixing plate 105 is fixedly connected to the first fixing plate 106.

[0052] As a specific implementation method of this embodiment, such as Figure 6-11 As shown, the angle adjustment mechanism 2 is provided with a rotating handle 201, a first limiting block 202, and a second limiting block 203; a second spring 204 is fixedly installed on one end of the rotating handle 201 near the baby seat 103, and the other end of the second spring 204 is fixedly connected to the inside of the upper end of the base frame 101, and is horizontally elastically slidably installed on the base frame 101 through the second spring 204; multiple locking blocks are evenly distributed on the outer circumference of the rotating handle 201 near the baby seat 103; the base frame 101 is provided with multiple slots corresponding to the locking blocks on the rotating handle 201, for fixing the rotating handle 201 on the base frame 101; the slots are located on the side of the locking blocks away from the baby seat 103; a handle is provided on the end of the rotating handle 201 away from the baby seat 103 for easy gripping; the second limiting block 203 is fixedly installed on the positioning frame 104; one end of the first limiting block 202 is fixedly installed on the end of the rotating handle 201 near the baby seat 103, and the other end is slidably installed on the second limiting block 203.

[0053] Manually hold both rotating handles 201 simultaneously and push them towards the infant seat 103. The rotating handles 201 compress the second spring 204 and then slide towards the infant seat 103. The locking block on the rotating handle 201 disengages from the locking groove on the base frame 101. At this time, rotate the rotating handle 201, thereby driving the infant seat 103 to rotate. After adjusting the infant seat 103 to a suitable angle, release the rotating handle 201. Under the action of the second spring 204, the rotating handle 201 returns to its original position and is re-fixed to the base frame 101. This method is easier for the elderly to use and is simple to operate, reducing the memory burden on the elderly compared to some complicated steps.

[0054] Considering that the reaction time of the elderly is slower than that of the younger, the present invention is provided with a first braking mechanism 3, such as Figure 12-17 As shown, the first braking mechanism 3 is equipped with a buffer plate 301, a front brake block 303, a rear brake lever 304, a limit bracket 305, and two transmission devices. The transmission devices are equipped with a first gear 306, a fourth gear 307, a third gear 308, a second transmission rod 309, a second gear 310, and a first transmission rod 311. The buffer plate 301 is equipped with a connecting rod 312, and a first spring 313 is sleeved on the connecting rod 312. The buffer plate 301 is elastically slidably mounted on the base frame 101 through the first spring 313. A push rod 302 is fixedly installed at the rear end of the buffer plate 301. Support rods four are symmetrically arranged on the left and right sides of the push rod 302. The lower rear ends of the two support rods four are equipped with racks, which are respectively connected to the two transmission devices symmetrically mounted on the base frame 101.

[0055] Specifically, such as Figure 14 and 16As shown in Figure -17, the limiting frame 305 is provided with two connecting rods, and the connecting rods are provided with sliders. The sliders are slidably mounted on the base frame 101, so that the limiting frame 305 is slidably mounted on the base frame 101. Two front brake blocks 303 correspond to the two front wheels and are symmetrically fixedly mounted on the limiting frame 305. Two rear brake rods 304 are symmetrically slidably mounted on the base frame 101. The upper front end is provided with a rack 3, and the rear end is provided with a rear brake block 314, which is used to brake the rear wheels. The base frame 101 is provided with a mounting bracket for the transmission device, and a rotating shaft 1011 is fixedly mounted on the mounting bracket. The left side of the push rod 302 and the transmission device mounted on the left side of the base frame 101 drive the left front brake block 303 and the rear brake rod 304 to brake the front and rear wheels. Specifically, the lower end of the first transmission rod 311 is fixedly mounted on the base frame 101. The front brake block 303 has a first rack at its upper end; a first gear 306 is rotatably mounted on a rotating shaft 1011, and the first gear 306 is located between the first transmission rod 311 and the push rod 302, and meshes with the first rack on the first transmission rod 311 and the rack on the push rod 302; a second gear 310 is fixedly mounted on one side of the first gear 306, and is also rotatably mounted on the rotating shaft 1011; a second transmission rod 309 and a third gear 308 are rotatably mounted on the other end of the rotating shaft 1011, and the third gear 308 is fixedly mounted on the second transmission rod 309; a fourth gear 307 is rotatably mounted on the base frame 101, and meshes with the second gear 310 and the third gear 308 simultaneously; the lower end of the second transmission rod 309 has an arc-shaped rack, and the rack on the front side of the rear brake lever 304 meshes with the arc-shaped rack.

[0056] When impacted, the buffer plate 301 slides backward, causing the push rod 302 to move. The push rod 302 drives the first gear 306 to rotate, which in turn drives the front brake block 303 to move forward, braking the front wheels. Simultaneously, while the push rod 302 drives the first gear 306 to rotate, it also drives the second gear 310 to rotate, which in turn drives the second transmission rod 309 to rotate counterclockwise. This causes the rear brake lever 304 to move backward, and the rear brake block 314 on the rear brake lever 304 brakes the rear wheels, thus stopping the stroller. Then, the buffer plate 301 returns to its original position under the action of the first spring 313, and the stroller can move again. Since the distance between the rear brake block 314 and the rear wheels is relatively short, the gear 3 on the front side of the rear brake lever 304 and the arc-shaped rack at the lower end of the second transmission rod 309 only need to mesh with each other for a short distance.

[0057] Similarly, the two transmission devices are symmetrically mounted on the base frame 101. While the push rod 302 moves back and forth, the two transmission devices drive the two front brake blocks 303 and the two rear brake levers 304 to brake the two front wheels and the two rear wheels respectively.

[0058] When impacted, the buffer plate 301, under the action of the first spring 313, can reduce the impact force on the stroller if the elderly fail to react in time, thus providing safer and more timely protection for the baby inside the stroller.

[0059] In addition, such as Figure 12 , 15 -16 and 18, the present invention also includes a second braking mechanism 4, which has a linkage rod 401 and a control slider 402; a slide rail is provided on the first fixed plate 106, and the control slider 402 is slidably mounted on the slide rail on the first fixed plate 106; one end of the linkage rod 401 passes through the slide rail on the first fixed plate 106 and is rotatably connected to the control slider 402, and the other end is rotatably connected to the limit frame 305; when the stroller needs to be braked, simply step on the control slider 402, the control slider 402 slides downward, driving the linkage rod 401 to move, and the linkage... The lever 401 pushes the limiting frame 305 forward, which in turn moves the front brake block 303 forward to brake the front wheel. Simultaneously, as the limiting frame 305 moves forward, it drives the first gear 306 to rotate, which in turn drives the rear brake lever 304 to move backward to brake the rear wheel. When the stroller needs to be moved again, simply release the control slider 402. When the limiting frame 305 moves forward, it will drive the buffer plate 301 to move backward. After releasing the control slider 402, the buffer plate 301 will reset under the action of the first spring 313, which will in turn drive the control slider 402 to reset.

[0060] Both the first braking mechanism 3 and the second braking mechanism 4 are simple and effective to use, and will not cause any burden to the elderly during use. Furthermore, both the first braking mechanism 3 and the second braking mechanism 4 brake the front and rear wheels of the stroller simultaneously, resulting in faster braking and reducing the risk of the stroller tipping over during sudden braking, thus increasing the safety factor for the baby.

[0061] Specifically, because elderly people have weaker physical strength, they may feel tired after pushing a stroller for a period of time, and there may not be a suitable place to rest in the surrounding environment. To cope with this situation, such as Figure 19-23 As shown, the present invention includes a liftable seat 5, which has a seat base 501, a seat plate 502 and a lifting platform. The front side of the seat base 501 is fixedly installed on a first fixed plate 106, and the rear ends of the rear side are rotatably installed with rear wheels. The rear brake lever 304 is slidably installed on the seat base 501. The middle position of the seat base 501 has a groove, and the lifting platform 508 is fixedly installed inside the groove. The seat plate 502 is fixedly installed on the upper end of the lifting platform 508. After adjusting the seat plate 502 to a suitable height by the lifting platform, one can sit on the seat plate 502 to rest.

[0062] As a specific implementation method of this embodiment, such as Figure 23As shown, the lifting platform 508 includes support rod 1 503, support rod 2 504, sliding frame 505, support rod 3 506, and cylinder 507. The sliding frame 505 is fixedly installed in the groove of the seat base frame 501. The two support rods 2 504 are symmetrically distributed front and rear, with their bottom ends fixedly installed on the sliding frame 505 and their top ends fixedly installed on the seat plate 502. The two support rods 1 503 are respectively cross-rotated on the corresponding support rods 2 504, and the two support rods 1 503 are located on the two support rods 2 506. On the outside of the second 504; the bottom ends of the two support rods 503 are slidably mounted on the sliding frame 505, and the upper ends are slidably mounted on the seat plate 502; support rods 506 are fixedly installed between the two support rods 503 and between the two support rods 504; two cylinders 507 are symmetrically fixedly installed on the support rods 506 between the two support rods 503, and the output ends of the two cylinders 507 are fixedly connected to the support rods 506 between the two support rods 504; the seat plate 502 is raised and lowered by the two cylinders 507.

[0063] The adjustable seat 5 is located at the rear of the stroller. When the elderly are resting on the seat 502, it is inconvenient for them to constantly monitor the baby. Therefore, if... Figure 1-2 As shown, two safety belt devices 6 are installed crosswise on the infant seat 103. The safety belts on the two safety belt devices 6 are crosswise and fixed in front of the infant's chest, which can safely restrain the infant on the infant seat 103 and prevent the infant from moving around while the elderly are resting, thus preventing accidents from happening.

[0064] As a specific implementation of this embodiment, the pusher 102 is provided with a cylinder control button (not shown in the figure), and the lifting and lowering of the seat plate 502 is controlled by pressing the control button; both the control button and the cylinder are electrically connected to the control device.

[0065] This invention uses a first braking mechanism 3 and a second braking mechanism 4 to immediately brake the stroller upon collision and buffer the impact force, thus safely and promptly braking the stroller. The lifting seat 5 and safety belt device 6 can provide a resting seat for the elderly while protecting the infant, relieving their fatigue. The structure is simple, easy to use and operate, and easy to promote.
