[0046] In related technologies, consumers frequently use the lifting function of cribs. Generally, users raise and lower the crib by stepping on the foot pedal. The foot pedal is usually located on the side of the lifting column. Since the crib has components such as the bottom frame, and the lifting column is located above the bottom frame, users need to raise their feet above the bottom frame to step on the foot pedal. This high foot height is not conducive to convenient control of raising and lowering the crib.

[0047] To address the problems existing in the aforementioned related technologies, this utility model provides a crib 100. By connecting the foot pedal component 500 to the bottom of the lifting component 300 and extending it towards the bottom and outer side of the crib 100, the user's foot can reach the foot pedal component 500 near the bottom of the lifting component 300, reducing the user's foot height, facilitating the user's stepping on the foot pedal component 500, and improving control over the stepping force. This allows for convenient control of raising or lowering the lifting component 300, thereby raising or lowering the crib body 400, and achieving convenient operation of raising and lowering the crib 100. A detailed description is provided below with reference to specific embodiments.

[0048] Combination Figures 1 to 7 As shown in the figure, an embodiment of the present invention provides a crib 100, including a base frame component 200, a lifting component 300 connected to the base frame component 200, a bed body 400 connected to one end of the lifting component 300 away from the base frame component 200, and a foot pedal component 500 connected below the lifting component 300. The foot pedal component 500 extends downward through the base frame component 200 and in a direction away from the center of the crib 100. The foot pedal component 500 is used to control the lifting of the lifting component 300.

[0049] For details, please refer to [link / reference]. Figure 1 , Figure 3 , Figure 4The lifting component 300 is connected to the end face of the lifting component (300) away from the bed body (400). The foot pedal component 500 extends through the base frame component 200 in a direction away from the center of the crib 100 and in a direction away from the lifting component 300. In actual use, when it is necessary to raise the lifting component 300, the user steps on the foot pedal component 500 to control the lifting component 300 to extend and raise, and drive the bed body 400 to move away from the base frame component 200 against gravity. When it is necessary to lower the lifting component 300, the user steps on the foot pedal component 500, and can also choose to use external force to press down on the bed body 400 to shorten and lower the lifting component 300, so that the height of the bed body 400 decreases. The user mentioned in this application can be understood as a person or machine that actually operates the lifting function of the crib 100, and is not specifically limited here.

[0050] It should be noted that, for details please refer to [link / reference]. Figure 1 , Figure 2 The crib 100 may further include multiple wheel sets 600, which may be connected and disposed on the side of the base frame 200 away from the lifting component 300, i.e., below the base frame 200, to facilitate the movement of the crib 100. The crib 100 may also include a tilt adjustment component 700 connecting the lifting component 300 and the bed frame 400, used to adjust the tilt angle of the bed frame 400. The tilt adjustment component 700 may be a telescopic drive device.

[0051] The number and type of the wheelset 600 are not specifically limited. It can be understood that the number of wheelset 600 can be 3, 4 or even more, and can be adapted to specific usage scenarios and functions. The type of any of the wheelset 600 can be fixed direction type, omnidirectional type, etc. The fixed direction type can be any one of front-to-back, left-to-right or diagonal type. This is only an example and is not specifically limited.

[0052] In some embodiments, please refer to the following for details. Figure 3 , Figure 4 The lifting component 300 includes a first base plate 310 connected to the base frame component 200, a first sleeve 320 connected to the first base plate 310, and a second sleeve 330 slidably sleeved around the first sleeve 320; wherein, when the lifting component 300 is raised, the second sleeve 330 moves away from the first base plate 310.

[0053] For details, please refer to [link / reference]. Figure 3 , Figure 4The first base plate 310 can be connected to the upper surface of the base frame component 200 by any fixed connection method such as screws, bolts, or welding, providing an installation base for the entire lifting component 300. The first sleeve 320 can be connected to the first base plate 310 by any fixed connection method such as screws, bolts, or welding. This is only an example and not a specific limitation. The second sleeve 330 is not directly connected to the first base plate 310. It can be understood that the first sleeve 320 is fixed, and the second sleeve 330 can move relative to the first sleeve 320 to realize the up and down movement of the second sleeve 330. The first sleeve 320 can provide guidance for the movement of the second sleeve 330. The cross-sectional dimension of the first sleeve 320 is smaller than that of the second sleeve 330. That is, the fixed connection between the first sleeve 320 and the first base plate 310 is achieved with a smaller connection area. The area where the fixed connection screws are set is smaller, thereby reducing the probability of mutual influence between fixed components and other movable components and reducing potential adverse interference between components.

[0054] In some embodiments, please refer to the following for details. Figure 3 , Figure 4 The lifting component 300 further includes a lifting unit 340, one end of which is connected to the first base plate 310, and the other end of which is connected to the end of the second sleeve 330 away from the first base plate 310. The lifting unit 340 is used to drive the second sleeve 330 to move relative to the first sleeve 320.

[0055] For details, please refer to [link / reference]. Figure 3 , Figure 4 One end of the lifting unit 340 can be fixedly connected to the first base plate 310 by any of the following methods: screws, bolts, or welding. The other end of the lifting unit 340 can be fixedly connected to the end of the second sleeve 330 away from the first base plate 310 by any of the following methods: screws, bolts, or welding. This is only an example and is not a specific limitation. The two ends of the lifting unit 340 abut against the first base plate 310 and the second sleeve 330 respectively. The lifting unit 340 can be extended and raised to drive the second sleeve 330 to move and rise.

[0056] In some embodiments, please refer to the following for details. Figure 3 , Figure 4The lifting unit 340 includes a lifting sub-part 341 and a valve sub-part 342; the first base plate 310 is provided with a first through hole H1; wherein, the lifting sub-part 341 is disposed in the first sleeve 320 and the second sleeve 330, and the valve sub-part 342 passes through the first through hole H1 and is used to abut against the foot pedal component 500.

[0057] For details, please refer to [link / reference]. Figure 3 , Figure 4 The lifting sub-part 341 can be a telescopic lifting element such as a gas spring or a hydraulic rod, which is only an example and not a specific limitation. The valve sub-part 342 passes through the first through hole H1 and protrudes to the side away from the bed body 400, and is used to abut against the foot pedal component 500. The valve sub-part 342 can be used to control the opening or closing of the lifting function of the lifting sub-part 341, so that the lifting sub-part 341 can extend and retract. In actual use, when it is necessary to raise the lifting sub-part 341, the force is applied to the valve sub-part 342 to control the lifting sub-part 341 to extend and raise, and drive the second sleeve 330 and the bed body 400 to move away from the base frame component 200 against gravity. When it is necessary to lower the lifting sub-part 341, the force is applied to the valve sub-part 342, and an external force can be used to press down the bed body 400 and drive the second sleeve 330 and the lifting sub-part 341, so that the lifting sub-part 341 shortens and lowers, so that the height of the bed body 400 decreases.

[0058] The valve sub-part 342 passes through the first through hole H1 and protrudes from the first base plate 310, facilitating contact between the foot pedal component 500 and the valve sub-part 342 to control its opening and closing. Optionally, when it is necessary to raise the lifting sub-part 341, the foot pedal component 500 can squeeze the valve sub-part 342 to activate it, causing the lifting sub-part 341 to extend and rise, thereby driving the second sleeve 330 and the bed 400 to overcome gravity and move away from the bottom. The frame component 200 moves in the direction of movement; when the extension and retraction of the lifting sub-section 341 is not required, the foot pedal component 500 can contact but not squeeze the valve sub-section 342 to close the valve sub-section 342; when it is necessary to lower the lifting sub-section 341, the foot pedal component 500 can squeeze the valve sub-section 342, and can choose to use external force to press down the bed body 400 and drive the second sleeve 330 and the lifting sub-section 341, so that the lifting sub-section 341 shortens and descends, thereby lowering the height of the bed body 400.

[0059] In some embodiments, please refer to the following for details. Figure 3 , Figure 4The foot pedal component 500 includes a pedal crank 510 and a first connecting portion 520; wherein, the first connecting portion 520 is connected to the first base plate 310, and the pedal crank 510 is rotatably connected to the first connecting portion 520, specifically, it can be hinged. Through the rotatable connection between the pedal crank 510 and the first connecting portion 520, when the user presses down on one end of the pedal crank 510, the other end of the pedal crank 510 moves upward, causing the pedal crank 510 to contact and press the valve sub-part 342, thereby activating the valve sub-part 342.

[0060] In some embodiments, please refer to the following for details. Figures 1 to 4 The pedal crank 510 includes a first sub-part 511 and a second sub-part 512 connected to the first connecting part 520. The first sub-part 511 and the second sub-part 512 are respectively disposed on both sides of the first connecting part 520. The first sub-part 511 is disposed corresponding to the valve sub-part 342 and is used to abut against the valve sub-part 342. On the horizontal projection of the crib 100, a part of the second sub-part 512 is located outside the area covered by the base frame component 200.

[0061] It is understood that the X-axis and Y-axis can form a plane, which can be a horizontal plane. The horizontal projection mentioned in this article refers to the orthographic projection of an object in the direction of the horizontal plane. The corresponding viewing angle can be a top view or a bottom view. No specific limitation is made here, and it will not be elaborated on later. The first sub-part 511 is correspondingly arranged with the valve sub-part 342. When the user steps down on the second sub-part 512, the first sub-part 511 can be moved upward through the first connecting part 520, so that the first sub-part 511 contacts and squeezes the valve sub-part 342, thereby activating the valve sub-part 342. The second sub-part 512 extends beyond the area covered by the base frame component 200, making it convenient for the user to step on the second sub-part 512, and further facilitating the user to control the raising and lowering of the crib 100.

[0062] In some embodiments, please refer to the following for details. Figure 3 The first sub-part 511 includes a first portion 5111 connected to the first connecting portion 520 and a first protrusion 5112 disposed on the first portion 5111; wherein, the first protrusion 5112 is disposed at the end of the first portion 5111 away from the first connecting portion 520, and the first protrusion 5112 is disposed on the surface of the first portion 5111 near the first base plate 310, and the portion of the first portion 5111 that contacts the valve sub-part 342 is spaced apart from the first protrusion 5112.

[0063] When the user steps down on the second sub-part 512, the first sub-part 511 moves upward, causing it to contact and squeeze the valve sub-part 342. If excessive force is applied, the valve sub-part 342 may be subjected to excessive pressure, potentially causing it to open too quickly or to an excessive degree. This is especially dangerous as it could cause the lifting sub-part 341 to rise too rapidly, posing a risk to the bed 400 and the infants within it. The first protrusion 5112 can limit the opening of the valve sub-part 342. When the user steps down on the second sub-section 512, the first sub-section 511 moves upward. If too much force is applied, the first protrusion 5112 will contact the first base plate 310, preventing excessive force from being transmitted to the valve sub-section 342. This avoids the valve sub-section 342 from opening too quickly or to too large an extent, thus preventing the risk of the lifting sub-section 341 rising too quickly. This provides some protection for the bed 400 and the infants in the bed 400, and also provides cushioning protection for the valve sub-section 342 and the lifting sub-section 341.

[0064] Specifically, the material of the first protrusion 5112 can be the same as that of the first portion 5111 and integrally formed; or, the elastic modulus of the material of the first protrusion 5112 can be less than that of the material of the first portion 5111, resulting in better cushioning performance. The height of the first protrusion 5112 can be adjusted according to actual conditions, and is not specifically limited here.

[0065] In some embodiments, please refer to the following for details. Figures 3 to 5 The second sub-part 512 includes a second part 5121 connected to the first connecting part 520 and a third part 5122 connected to the second part 5121; wherein, the third part 5122 is disposed at the end of the second part 5121 away from the first connecting part 520, and the third part 5122 includes a first surface S1 and a second surface S2 disposed opposite to each other, the first surface S1 is disposed on the side of the second surface S2 near the first base plate 310, and the included angle between the first surface S1 and the second part 5121 is greater than the included angle between the second surface S2 and the second part 5121.

[0066] Understandably, please refer to the details. Figures 3 to 5The second part 5121 extends downward and away from the center of the crib 100. Specifically, the second part 5121 extends obliquely downward, towards the side away from the center of the crib 100 and downward towards the base frame component 200. This helps the second part 5121 avoid the base frame component 200 and reduces the interference effect of the base frame component 200 on the second part 5121. The third part 5122 includes a first surface S1 and a second surface S2 disposed opposite to each other. The first surface S1 is disposed on the side of the second surface S2 near the first base plate 310. The angle between the first surface S1 and the second part 5121 is greater than the angle between the second surface S2 and the second part 5121. The included angle between parts 5121 is marked as α1, and the included angle between the second surface S2 and the second part 5121 is marked as α2, where α1 > α2. The first surface S1 can be understood as the upper surface of the third part 5122, and the second surface S2 can be understood as the lower surface of the third part 5122. The third part 5122 mainly extends away from the center of the crib 100. The upper and lower surfaces of the third part 5122 are not parallel. Compared to when the upper and lower surfaces are parallel, more material is cut off from the lower part of the third part 5122 during manufacturing, thereby increasing the space of the corresponding part of the lower surface. This facilitates extending the stepping stroke and avoids interference between the third part 5122 and the ground. At the same time, the irregular design also has a certain aesthetic effect.

[0067] In some embodiments, please refer to the following for details. Figure 6 The first sub-part 511 is provided with a second through hole H2. The first connecting part 520 includes a first connecting plate 521 and a second connecting plate 522, a first pin 523 and a second pin 524, which are spaced apart. The first sub-part 511 is sandwiched between the first connecting plate 521 and the second connecting plate 522. The first pin 523 passes through the first sub-part 511 through the second through hole H2. The two ends of the first pin 523 are respectively connected to the first connecting plate 521 and the second connecting plate 522 so that the pedal crank 510 is rotatably connected to the first connecting part 520. The second pin 524 is provided on the side of the first sub-part 511 away from the first pin 523. The two ends of the second pin 524 are respectively connected to the first connecting plate 521 and the second connecting plate 522.

[0068] Specifically, the first connecting plate 521 may include a first connecting hole and a second connecting hole, and the second connecting plate 522 includes a third connecting hole and a fourth connecting hole. The first connecting hole and the third connecting hole are correspondingly arranged, and the second connecting hole and the fourth connecting hole are correspondingly arranged. The first pin 523 passes through the first connecting hole, the third connecting hole, and the second through hole H2 to rotatably connect the pedal crank 510 to the first connecting part 520. The second pin 524 passes through the second connecting hole and the fourth connecting hole, and the second pin 524 is located on the side of the first sub-part 511 away from the first pin 523. It is easy to understand that the first connecting hole, the second connecting hole, the third connecting hole, and the fourth connecting hole are not labeled in the figure.

[0069] It is understood that the first sub-part 511 is connected to the first connecting plate 521 and the second connecting plate 522 via the first pin 523. The first sub-part 511 can rotate relative to the first connecting plate 521 and the second connecting plate 522 via the first pin 523. The first pin 523 is equivalent to the rotation axis of the first sub-part 511. At the same time, the first pin 523 can restrict the horizontal movement of the first sub-part 511. The second pin 524 can contact the first sub-part 511 or maintain a certain distance from the first sub-part 511. During assembly, the diameter of the second through hole H2 of the first sub-part 511 is larger than the diameter of the first pin 523, which facilitates assembly and rotation of the first sub-part 511. However, this also causes the first sub-part 511 to have some bounce. The second pin 524 can prevent the first sub-part 511 from having large bounce and improve the overall stability of the foot pedal component 500.

[0070] In some embodiments, please refer to the following for details. Figure 7 The bed body 400 includes two first long sides 410 and two first short sides 420 arranged opposite to each other; wherein, on the horizontal projection of the crib 100, the second sub-part 512 intersects with the first long side 410, or the extension line of the extension direction of the second sub-part 512 intersects with the first long side 410.

[0071] Understandably, please refer to the details. Figure 7 On the horizontal projection of the crib 100, the second sub-part 512 extends from the corresponding long side of the crib 400. Figure 7The diagram illustrates the intersection of the second sub-part 512 and the first long side 410. It's easy to understand that the second sub-part 512 can be made shorter, meaning the extension line of the second sub-part 512 intersects the first long side 410, saving space and reducing the risk of the user tripping. The foot pedal is located at the corresponding position on the long side, where the space is larger than that on the short side, making it easier to install the foot pedal component 500. Furthermore, since infants are typically held horizontally, and the user stands parallel to the long side, placing the infant inside the bed 400 makes it even easier to step on the foot pedal component 500.

[0072] In some embodiments, please refer to the following for details. Figures 2 to 6 The second sub-part 512 is provided with a first groove G1, which faces the base frame component 200 and is recessed in a direction away from the base frame component 200; wherein the first groove G1 corresponds to at least one sidewall of the base frame component 200.

[0073] The first groove G1 corresponds to at least one side frame of the base frame component 200, which can reduce the interference between the second sub-part 512 and the base frame component 200, reduce the risk of the side frame of the base frame component 200 bumping and squeezing the second sub-part 512, thereby reducing the abnormal rotation of the second sub-part 512 and the first sub-part 511, reducing the risk of abnormal squeezing of the valve sub-part 342 by the foot crank 510, reducing the risk of the crib being accidentally raised or lowered, and enhancing the safety and reliability of the crib.

[0074] In some embodiments, please refer to the following for details. Figure 3 , Figure 6 The second sub-part 512 further includes a fourth part 5123, which is disposed on the third part 5122. On the horizontal projection of the crib 100, in the extending direction perpendicular to the second sub-part 512, the width of the fourth part 5123 is greater than the width of the third part 5122.

[0075] It is understood that the fourth part 5123 can serve as a shielding step for the third part 5122. The fourth part 5123 may include a planar part parallel to the first surface S1 and a vertical part perpendicular to the first surface S1. The planar part and the vertical part are connected and disposed together. The vertical part can shield the third part 5122 while also strengthening the overall mechanical strength of the fourth part 5123.

[0076] In some embodiments, the height difference between the highest point and the lowest point of the third portion 5122 is between 10mm and 20mm. Specifically, it can be 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, or 20mm. These are just examples and not specific limitations. The most suitable height difference can be set according to factors such as the actual pedaling distance.

[0077] In some embodiments, the distance between the vertical portion and the lowest point of the wheelset 600 is 50mm to 200mm. Preferably, it can be 50mm to 70mm, specifically 50mm, 55mm, 60mm, 65mm, and 70mm. These are just examples and not specific limitations. The most suitable distance can be set according to factors such as actual pedaling stroke.

[0078] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
