Description

Technical Field

[0001] This utility model relates to the field of electronic weighing technology, and more specifically, to an electronic baby scale and a baby crib. Background Technology

[0002] Baby scales typically consist of a base and a weighing mechanism mounted on the base. Currently, these scales are usually used in conjunction with a crib; for example, the base is installed on the crib frame, the crib board is placed on the weighing mechanism, and the baby can be weighed while lying on the crib board.

[0003] However, installing such baby scales on cribs often presents some drawbacks. For example, to save space, cribs are usually placed in a corner of the room when not in use. Also, due to the large number of baby items, some inevitably accumulate around the crib, such as changing tables and folded playmats. Therefore, to facilitate the caregiver moving the scale to the crib for weighing, a path needs to be cleared around these items, making the weighing process inconvenient. Additionally, some room corners may have hanging objects, such as storage cabinets, limiting the distance between the crib's surface and these objects. This makes it inconvenient to place the baby directly on the crib for weighing; the entire crib needs to be moved out of the corner, requiring the removal of surrounding items first, which is extremely inconvenient. Utility Model Content

[0004] The problem solved by this invention is that the baby electronic scale is inconvenient to weigh after being installed on the baby's crib.

[0005] To solve the above problems, this utility model provides an electronic baby scale and a baby crib.

[0006] In a first aspect, this utility model provides an electronic baby scale, including a scale body; two supports are symmetrically connected to both sides of the scale body; a connector is connected to the bottom of the support; a sliding channel is formed between the support and the connector, extending along the corresponding side edge of the scale body; a slide rod is inserted in the sliding channel, the slide rod can slide relative to the sliding channel, and both ends can extend outside the sliding channel.

[0007] The beneficial effects of this new baby electronic scale are as follows: After the connecting piece is installed at the bottom of the bracket, a sliding channel for the slide bar is formed between it and the bracket. The scale body can be adjusted along the slide bar, widening the range of positions the scale body can occupy. Therefore, when using the baby electronic scale, the scale body can be adjusted to a convenient position for weighing, improving the convenience of weighing. Specifically, when applied to a crib, the two ends of the slide bar are connected to the support structure of the crib board, and the crib board is connected to the scale plate. The baby can be placed on the crib board for weighing. If the crib is located in a corner, and other items around it make it difficult to approach (or the corner position makes it inconvenient to place the baby on the crib board), the crib board can be pulled, driving the crib board and scale body to slide along the slide bar, adjusting the crib board and scale body from the corner position to the user's side for weighing. This structure not only solves the problem of users being unable to approach the crib board but also avoids the inconvenience of moving the entire crib from the corner, improving the practicality and applicability of the baby electronic scale and the crib.

[0011] Optionally, a positioning sleeve is provided in the sliding channel; the positioning sleeve is fitted over the slide rod.

[0012] Optionally, the positioning sleeve has protrusions at both the upper and lower ends; and the slide groove one and slide groove two each have recesses corresponding to the protrusions.

[0013] Optionally, the scale body includes a weighing plate and load cells; the load cells are installed at the four corners of the weighing plate; both ends of the weighing plate are connected to a bracket.

[0014] Optionally, a cover plate is installed on the weighing plate; the cover plate has clearance holes corresponding to the weighing sensors.

[0015] Secondly, this utility model provides a baby crib, including an electronic baby scale.

[0032] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Although some embodiments of this utility model are shown in the drawings, it should be understood that this utility model can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this utility model. It should be understood that the drawings and embodiments of this utility model are for illustrative purposes only and are not intended to limit the scope of protection of this utility model.

[0033] The term "comprising" and its variations as used herein are open-ended, meaning "including but not limited to"; the term "based on" means "at least partially based on"; the term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments"; and the term "optionally" means "optional embodiments". Definitions of other terms will be given in the following description. It should be noted that the concepts of "first," "second," etc., mentioned in this utility model are only used to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0034] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0035] like Figure 1-7 As shown in the figure, an embodiment of the present invention provides an electronic baby scale, including a scale body; two supports 2 are symmetrically connected to both sides of the scale body; a connector 6 is connected to the bottom of the support 2; the support 2 and the connector 6 form a sliding channel extending along the corresponding side edge of the scale body (i.e., the side edge where the support 2 and the connector 6 are located); a slide rod 10 is inserted into the sliding channel, the slide rod 10 can slide relative to the sliding channel, and both ends extend outside the sliding channel; the two ends of the slide rod 10 are used to support the entire electronic baby scale; by limiting the slide rod 10 relative to the sliding channel, the electronic baby scale can be supported. The sliding channel is slidable, and both ends of the slide rod 10 are located outside the sliding channel, ensuring that the connector 6 and the scale body can slide on the slide rod 10 to achieve position adjustment; at the same time, when both ends of the slide rod 10 are connected to an external structure such as the lifting frame (9) of a baby bed, the external structure can block and limit the two ends of the slide rod 10, that is, the setting of the connector 6 can limit the structure as a whole. For example, when the scale body slides along the slide rod 10 to the limit position, the connector 6 will contact the external structure to ensure that the connector 6 and the scale body will not fall off the slide rod.

[0036] Specifically, after the connector 6 of the baby electronic scale is installed at the bottom of the bracket 2, it forms a sliding channel for the slide bar 10 between the connector 6 and the bracket 2. The scale body can be adjusted along the slide bar 10, which expands the range of positions of the scale body. In this way, when the baby electronic scale is in use, the scale body can be moved along the slide bar 10 to adjust to a position that is easy to operate for weighing, which improves the convenience of weighing. When specifically applied to a baby bed, the two ends of the slide bar 10 are connected to the support structure of the bed board (e.g., the lifting frame (9)). The bed board is connected above the scale board. The baby can be placed on the bed board for weighing. If the baby bed is in a corner and other items are placed around it, making it difficult for the baby bed to be approached, it is inconvenient for the user to place the baby on the bed board for weighing. The user can pull the bed board to drive the bed board and the scale body to slide along the slide bar 10, so that the bed board and the scale body are adjusted from the corner position to the side of the user. This makes it convenient for the user to place the baby on the bed board for weighing, solving the problem that it is inconvenient for the user to approach the bed board. This design improves the weighing convenience of the electronic scale and the applicability of baby cribs. Furthermore, if there is a hanging object (such as a storage cabinet) above the bed board in the corner, and the height distance between the hanging object and the bed board is limited, making it inconvenient for the user to place the baby directly on the bed board, the user can pull the bed board to drive the bed board and scale body to slide along the slide bar 10, so that the bed board and scale body are moved out from directly under the hanging object before weighing. This eliminates the need to move the entire baby crib out of the corner, avoiding the inconvenience of moving the entire baby crib out of the corner, thus improving the weighing convenience of the baby electronic scale and the applicability of baby cribs.

[0037] Optionally, the two sliding channels can be set to different widths. The gap between one sliding channel and the slide rod 10 is between 1mm and 3mm to limit the offset of the slide rod 10 on one side. The gap between the other sliding channel and the slide rod 10 is greater than 1.5 times the diameter of the slide rod 10 and less than 2.5 times the diameter of the slide rod to avoid interference when the bed is raised or lowered on one side.

[0038] Specifically, the different widths of the design facilitate the installation of the baby scale during use. Usually, the narrower slide bar 10 is installed on the external support mechanism first; the wider slide bar 10 can be adjusted laterally within the sliding channel to adapt to different installation positions and reduce the difficulty of installation.

[0039] Optionally, a sliding groove 1 can be provided at the bottom of the bracket 2; a sliding groove 2 can be provided at the connector 6; the space formed between the sliding groove 1 and the sliding groove 2 is a sliding channel.

[0040] Specifically, the bracket 2 and the connector 6 can be made of thin plates, which are continuously bent to form the first and second slides; this structure can reduce weight and space occupation.

[0041] Furthermore, the connection between connector 6 and bracket 2 should preferably be detachable, facilitating disassembly and assembly, and also making it easier to replace one of the components. For example, it can be connected by bolts. Specifically, screw holes can be made at corresponding positions on connector 6 and bracket 2, and bolts and nuts can be used for connection.

[0042] Of course, the installation position of connector 6 on bracket 2 can also be determined according to the actual application scenario (under normal conditions, the scale body is located directly above the slide bar 10, that is, when connector 6 is installed at one end of bracket 2, connector 6 should also be near the end of slide bar 10). For example, when connector 6 is installed in the middle of bracket 2, scale plate 1 and bracket 2 can slide along slide bar 10 to both sides of bracket 2; when connector 6 is installed on one side of bracket 2 (left or right), scale plate 1 and bracket 2 can only slide along slide bar 10 to the other side of bracket 2 (right or left). Please refer to... Figure 5-6 As shown in the diagram, connector 6 is installed on one side of bracket 2 (defined as the left side). When the two ends of slide rod 10 are connected to the external structure, the close proximity or even contact between the external structure and connector 6 makes it difficult for bracket 2 and connector 6 to slide further to the left; they can only slide to the right, thus achieving position adjustment. By changing the installation position of connector 6 on bracket 2, the applicable scenarios for the baby scale can be expanded.

[0043] Optional, please refer to Figure 3-7 A positioning sleeve 7 can also be installed within the sliding channel. The positioning sleeve 7 is fitted around the outside of the slide rod 10 and has a channel coaxial with the sliding channel, which is used for the slide rod 10 to pass through. By installing the positioning sleeve 7, the friction between the slide rod 10 and the connecting piece 6 and the bracket 2 can be reduced. When wear occurs, the positioning sleeve 7 can be replaced. Furthermore, the installation method of the positioning sleeve 7 is not limited. For example, when the connecting piece 6 is connected to the support plate 17 by bolts, the upper and lower ends of the positioning sleeve 7 can respectively press against the second surface of the slide groove of the connecting piece 6 and the first surface of the slide groove of the bracket 2. Of course, the upper and lower ends of the positioning sleeve 7 can also be connected to the first and second slide grooves by bolts. Furthermore, protrusions can be provided at both the upper and lower ends of the positioning sleeve 7. Recesses corresponding to the protrusions are provided on both the first and second slide grooves. During installation, the protrusions and recesses cooperate to achieve quick positioning and installation, improving installation efficiency and accuracy.

[0044] Optional, please refer to Figure 1-7The scale body includes a weighing plate 1 and load cells 3. The load cells 3 are installed at the four corners of the weighing plate 1, and the bottom of the load cells 3 has grooves to avoid weighing interference. Both ends of the weighing plate 1 are connected to the brackets 2. Specifically, the two ends of the weighing plate 1 and the brackets 2 can be bolted together or directly welded together. Considering the overall weight and structural strength, a hole can be made in the middle of the weighing plate 1, and a bending part can be set at the hole. Of course, a bending part can also be set on the outer periphery of the weighing plate 1, and multiple bending parts can form a bending reinforcement structure of the weighing plate 1.

[0045] Optionally, a cover plate 4 is installed on the weighing plate 1. The cover plate 4 has clearance holes and clearance grooves corresponding to the weighing sensor 3. The clearance grooves can prevent interference with the mounting screws on the bracket 2. The cover plate 4 is used to cover internal parts, increase aesthetics, or reduce the entry of debris into the weighing body. Furthermore, a rubber pad 5 can be set on the top of the weighing sensor 3. The crib body is fixed to the rubber pad 5 with screws. The rubber pad 5 has a cushioning effect. The cushioning pad is preferably cylindrical. A second bending part is set in the middle of the cover plate 4. The bending structure formed by the second bending part surrounds the bending structure formed by the first bending part.

[0046] This utility model provides a baby crib, which includes the baby electronic scale described above.

[0047] Specifically, the crib includes an electronic scale and a slide bar 10; both ends of the slide bar 10 are connected to the crib frame; the crib frame has mounting positions for connectors 6; connectors 6 and brackets 2 are detachably connected. The crib has two states: the first state is with the electronic scale on the crib frame, in which case the electronic scale is mounted on the crib frame via the slide bar 10, the bed board is mounted on the electronic scale, and the baby is placed on the bed board for weighing. The second state is with the electronic scale removed from the crib frame, in which case connectors 6 and brackets 2 can be disassembled; then brackets 2 and other parts of the electronic scale can be removed together, and connectors 6 can be directly installed on the crib frame.

[0048] Please combine Figure 8-12 In this embodiment, the crib body may include a base 16, a drive mechanism, a lifting frame 9, and a tray 17; a drive mechanism is provided at each of the opposite ends of the base 16, and each drive mechanism is driven connected to a lifting frame 9. The top ends of the lifting frame 9 are respectively connected to the two ends of the slide rod 10; the tray 17 is placed on the scale body.

[0049] In use, the infant can lie down and rest on the tray 17, and the scale can measure the infant's weight. At the same time, the drive mechanism can drive the lifting frame 9 to rise or fall, thereby realizing the overall lifting and lowering of the scale plate 1 and the tray 17. When the drive mechanisms at the left and right ends of the base 16 synchronously drive their respective connected lifting frames 9 to rise or fall, the tray 17 can be raised or lowered horizontally. When the drive mechanism at the left end of the base 16 drives its connected lifting frame 9 to rise / fall, and the drive mechanism at the right end of the base 16 drives its connected lifting frame 9 to fall / rise, the tray 17 can be rocked left and right.

[0050] Optional, please refer to Figure 9-11 The lifting frame 9 includes a first lifting rod 901, a second lifting rod 902, and a connecting plate 903. The first lifting rod 901 and the second lifting rod 902 are arranged in an X-shape and hinged together. The top of the first lifting rod 901 is slidably connected to a first adjustment hole on the connecting plate 903, and a quick-release assembly is provided between its bottom and the base 16. The top of the second lifting rod 902 is hinged to the connecting plate 903, and its bottom is slidably connected to a second adjustment hole on the base 16. The first and second adjustment holes are strip-shaped holes and extend in parallel directions. The two ends of the slide rod 10 are connected to the two ends of the connecting plate 903 of each lifting frame 9. If necessary, to facilitate the movement of the connecting plate 903, a movable groove 904 can be preset between the slide rod 10 and the connecting plate 903. The movable groove 904 can serve as a space for the connecting plate 903 to move. Each first lifting rod 901 is connected to a drive mechanism; the drive mechanism can drive the bottom of the second lifting rod 902 to slide in the second adjustment hole to realize the overall raising or lowering of the lifting frame 9, thereby realizing the raising and lowering of the scale body and the pallet 17.

[0051] It should be noted that when the bottom of the first lifting rod 901 is connected to the base 16 via the quick-release assembly, the bottom of the first lifting rod 901 and the base 16 can rotate relative to each other. Therefore, when the drive mechanism drives the second lifting rod 902 to slide, the first lifting rod 901 and the second lifting rod 902 can cause the connecting plate 903 to rise or fall. When the bottom of the first lifting rod 901 is separated from the base 16 via the quick-release assembly, since the bottom of the first lifting rod 901 is in a free state, even if the drive mechanism drives the second lifting rod 902 to slide, the first lifting rod 901 and the second lifting rod 902 will no longer cause the connecting plate 903 to rise or fall; instead, the entire assembly will translate. Furthermore, when the bottom of the first lifting rod 901 is separated from the base 16 via the quick-release assembly, since the bottom of the first lifting rod 901 is in a free state, the connecting plate 903, the support plate 17, the weighing plate 1, the first lifting rod 901 and the second lifting rod 902 as a whole can be rotated around the bottom of the second lifting rod 902 as the pivot point. When the rotation angle is large enough (e.g., 90°, 120°), the upper surface of the base 16 will be exposed as completely as possible, making it convenient for staff to clean the surface of the base 16, the bottom surfaces of the two lifting rods, the bottom surface of the connecting plate 903 and the bottom surface of the support plate 17.

[0052] When the drive mechanisms at both ends of the base 16 synchronously drive their respective connected second lifting rods 902 (i.e., the two connecting plates 903 rise and fall synchronously), the horizontal lifting of the tray 17 can be achieved; when the drive mechanisms at both ends of the base 16 do not synchronously drive their respective connected second lifting rods 902, when the drive mechanism at the left end drives the second lifting rod 902 to slide, causing the connecting plate 903 at the left end to rise / fall, and the drive mechanism at the right end drives the second lifting rod 902 to slide, causing the connecting plate 903 at the right end to fall / rise, that is, when the left and right ends of the tray 17 are at different heights, the rocking function of the crib can be achieved.

[0053] Optionally, the drive mechanism can be an electrically controlled electric push rod; the movable end of the electric push rod is connected to the bottom of the second lifting rod 902. Of course, to protect the drive mechanism and improve safety, a protective cover can be installed on the base 16. In addition to the protective cover, a second adjustment hole can be made on the side wall of the protective cover.

[0054] Optionally, please combine Figure 12 The quick-release assembly may include a connecting shaft 8, a fixing post 11, and a pin.

[0055] The outer wall of the connecting shaft 8 is connected to the first lifting rod 901, and a through hole 802 is coaxially formed inside it; the fixing column 11 is mounted on the base 16, and a limiting hole 1101 is recessed at one end near the connecting shaft 8; the limiting hole 1101 is coaxial with the through hole 802; the pin includes a driving part 14, a moving part 13 and a limiting part 12 connected in sequence; one end of the driving part 14 is connected to the moving part 13, and the other end is located outside the through hole 802; the moving part 13 is located inside the through hole 802, and its outer wall is flush with the inner wall of the through hole 802. Contact; one end of the limiting part 12 is connected to the moving part 13, and the other end is engaged with the limiting hole 1101; the moving part 13 can be axially adjusted within the through hole 802 by the driving part 14. For example, when the moving part 13 moves to the point where the limiting part 12 is located within the limiting hole 1101, the first lifting rod 901 is quickly connected to the base 16; when the moving part 13 moves to the point where the limiting part 12 is completely disengaged from the limiting hole 1101, the first lifting rod 901 is quickly separated from the base 16. Furthermore, the fit between the limiting part 12 and the limiting hole 1101 can be varied. For example, it can be a threaded fit, where the limiting part 12 is a round shaft with external threads, and the limiting hole 1101 is a round hole with mating internal threads. Rotating the driving part 14 to rotate the limiting part 12 allows for the separation and connection of the limiting part 12 and the fixed post 11. Alternatively, it can be a suitable transition fit or clearance fit (i.e., the outer contour of the limiting part 12 is similar to the contour dimensions of the limiting hole 1101). Applying a certain external force to the driving part 14 allows for the separation and connection of the limiting part 12 and the fixed post 11. Similarly, the fit between the moving part 13 and the through hole 802 can be referenced to that between the limiting part 12 and the limiting hole 1101. The difference is that when using a transition fit or threaded connection, the bottom of the first lifting rod 901 needs to be rotatably connected to the outer wall of the connecting shaft 8 (allowing relative rotation). Of course, for ease of use, a handle 15 can also be installed at the end of the driving part 14 away from the moving part 13. Please refer to... Figure 12 In order to reduce the overall volume of the quick-release assembly and facilitate cleaning of the base 16, the diameter of the moving part 13 can be designed to be larger than that of the driving part 14 and the limiting part 12, thereby reducing the volume of the matching limiting hole 1101 and the fixing post 11.

[0056] Optionally, the end of the connecting shaft 8 near the drive part 14 extends inward to form an annular step 801. To prevent the moving part 13 from disengaging from the through hole 802, the diameter of the annular step 801 should be smaller than the diameter of the moving part 13. To facilitate the normal movement of the drive part 14, the diameter of the annular step 801 should not be smaller than the diameter of the drive part 14, and preferably larger than the diameter of the drive part 14.

[0057] Specifically, when the driving part 14 drives the moving part 13 to move away from the limiting hole 1101, when the moving part 13 comes into contact with the annular step 801, the moving part 13 can no longer move and will not detach from the through hole 802, thus improving the stability of the structure.

[0058] The advantages of the crib in this embodiment over the prior art are not only the advantages of the aforementioned baby electronic scale, but also the ability to raise and lower the tray 17 and rock it, and the ease of cleaning the base 16.

[0059] 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.
