DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the drawings of the present invention, the X direction represents the left, and the direction opposite to the X direction is the right; the Y direction represents the front, and the direction opposite to the Y direction is the back; the Z direction represents the top, and the direction opposite to the Z direction is the bottom.

[0027] If there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0028] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a baby electronic scale, comprising a base 1 and a support plate 2 , wherein the support plate 2 is arranged above the base 1 .

[0029] The base 1 includes a first support portion 11 and a second support portion 12 which are symmetrically arranged, and the first support portion 11 and the second support portion 12 are fixedly connected by two parallel connecting frames 13. The connecting frame 13 is a long rod-shaped structure, one end of the connecting frame 13 is connected to the end of the first support portion 11, and the other end of the connecting frame 13 is connected to the end of the second support portion 12, so that the first support portion 11, the second support portion 12 and the two connecting frames 13 enclose a rectangular area.

[0030] A first mounting groove 111 is provided on the upper surface of the first support portion 11 facing the support plate 2, and a second mounting groove 121 is provided on the upper surface of the second support portion 12 facing the support plate 2. The top view shapes of the first mounting groove 111 and the second mounting groove 121 are both trapezoidal, and the long side of the trapezoid is closer to the center of the base 1 than the short side of the trapezoid, so that the space occupied by the base 1 can be minimized.

[0031] A weighing sensor 3 is provided in each of the first mounting groove 111 and the second mounting groove 121, and the bottom of the support plate 2 is connected to the weighing sensor 3. When a heavy object or a baby is placed on the support plate 2, the weighing sensor 3 can sense the weight of the object or baby on the support plate 2. In order to ensure that the objects on the support plate 2 are placed stably, a circle of enclosure extending upward is provided at the edge of the support plate 2 to reduce the risk of the objects sliding off the support plate 2.

[0032] Furthermore, the base 1 can be assembled onto other medical devices, so that the baby electronic scale of this embodiment can be conveniently integrated into other medical devices.

[0033] For example, the baby incubator generally includes a bracket and a platform arranged on the bracket, and a baby box is arranged on the platform. The baby box is generally covered on the platform to form a space for accommodating the baby. In order to integrate the baby electronic scale of this embodiment into the baby incubator, we only need to fix the base 1 to the upper surface of the platform, and the connection method can be screw connection, welding or riveting, etc., or a more convenient detachable connection can be adopted. Then, auxiliary parts such as a cushion for the baby to lie on are arranged on the support plate 2, and then the baby box is covered on the upper part of the support plate 2. Finally, the detection signal of the weighing sensor 3 can be connected to the display or control device of the baby incubator. Since the first support part 11 and the second support part 12 are connected only by the connecting frame 13, there is a large space between the first support part 11 and the second support part 12, which can accommodate other auxiliary parts of the baby incubator, such as electrical components or parts.

[0034] The above is just an example, and in fact the electronic baby scale of this embodiment can also be connected with other baby medical equipment, such as jaundice treatment equipment, transport incubator, etc. It can be seen that the electronic baby scale of this embodiment has good applicability in combination with other medical equipment.

[0035] Of course, the baby electronic scale of this embodiment can also be used alone as a baby weighing device.

[0036] On the other hand, it can be seen from the above description that the baby electronic scale of this embodiment has a simple structure and is easy to assemble. During assembly, it is only necessary to install the weighing sensor 3 into the first installation groove 111 and the second installation groove 112, and then install the support plate 2 on the top of the weighing sensor 3. Due to this simple bottom-up installation method, there is no difficult operation relief, which is conducive to ensuring the reliability of the connection structure between the components, so the stability of the electronic scale is better.

[0037] Preferably, the weighing sensor 3 is a balance beam sensor. The balance beam sensor has a rectangular shape, and the strain zone is in the middle of the sensor. One end of the sensor is used to fix to the bottom accessories, and the other end is used to bear the pressure of the upper accessories, which can bear the weight well. Traditional baby electronic scales use four rectangularly distributed weighing sensors, which makes assembly inconvenient and requires fusion of the analog signals of the four sensors, and the circuit will be more complicated. This embodiment uses two balance beam weighing sensors, which reduces the number of weighing sensors and simplifies the assembly process. The fusion of two weighing signals is simpler and more accurate than the fusion of the existing four weighing signals.

[0038] Combination Figure 3 and Figure 5 As shown, optionally, a support platform 5 is respectively provided at the bottom of the first installation groove 111 and the second installation groove 121, and the weighing sensor 3 is installed on the upper surface of the support platform 5. Specifically, the weighing sensor 3 is a balance beam sensor, one end of the balance beam sensor is connected to the support platform 5 by two screws, and a first gasket 41 is provided between the balance beam sensor and the support platform 5, and the balance beam sensor, the first gasket 41 and the support platform 5 can be pressed together by tightening the two screws.

[0039] A clearance cavity is provided at the bottom of the support platform 5. Specifically, the middle part of the support platform 5 is arched upward, so that a cavity is formed between the middle part of the support platform 5 and the bottom of the first mounting groove 111 / the second mounting groove 121, and the cavity is the clearance cavity. The edge of the support platform 5 is fixedly connected to the bottom of the first mounting groove 111 or the second mounting groove 121, and the fixed connection method can be welding, screw connection or riveting. It can be seen that the existence of the clearance cavity of the support part 5 allows the support platform 5 to raise the weighing sensor 3 to a certain height relative to the first support part 11 and the second support part 12. On the one hand, it ensures that the base 1 will not interfere with the weighing sensor 3 when it is integrated and assembled with other medical equipment, and on the other hand, it reduces the vibration and interference from the bottom of the base 1 felt by the weighing sensor 3.

[0040] Both ends of the support platform 5 are provided with flanges parallel to the bottom of the first installation groove 111 or the second installation groove 121, and the flanges can increase the contact area between the support platform 5 and the bottom of the first installation groove 111 or the second installation groove 121 to ensure connection reliability.

[0041] Combination Figure 2 , Figure 4 and Figure 5 As shown, based on the above embodiment, preferably, a connection cover 6 is provided between the weighing sensor 3 and the support plate 2. The extension direction of the connection cover 6 is perpendicular to the connection frame 13. The connection cover 6 includes a clearance groove recessed upward from its bottom surface, and the upper part of the weighing sensor 3 is located in the clearance groove. A shock-absorbing probe 7 is provided at each end of the connection cover 6, and the support plate 2 is connected to the connection cover 6 through the shock-absorbing probe 7.

[0042] A first screw hole is provided at each end of the connection cover 6. The shock-absorbing probe 7 is cylindrical, and a second screw hole matching the first screw hole is provided at the center of the shock-absorbing probe 7. The support plate 2 is provided with rectangularly distributed fixing screw holes 23, and the fixing screw holes 23 match the first screw holes and the second screw holes, so that the support plate 2, the shock-absorbing probe 7 and the connection cover 6 can be fixedly connected together by screws. Among them, the shock-absorbing probe 7 can be made of rubber material or other materials with shock-absorbing effect.

[0043] The connection cover 6 is also provided with two third screw holes 61 for connecting the weighing sensor 3. As we know, one end of the weighing sensor 3 has been connected to the support platform 5, and the other end of the weighing sensor 3 is connected to the connection cover 6 through the third screw hole 61. In addition, a second gasket 42 is provided between the weighing sensor 3 and the bottom of the connection cover 6, and the three are also connected by screws.

[0044] In this embodiment, the one-point support of a weighing sensor 3 is converted into two-point support for the support plate 2 through the connecting cover 6, so that the two weighing sensors 3 can realize four-point support for the support plate 2 through the two connecting covers 6, thereby ensuring stable support for the support plate 2. Although only two weighing sensors 3 are used in this embodiment, stable support for the support plate 2 can still be ensured. In addition, since a part of the top of the weighing sensor 3 is hidden in the clearance groove of the connecting cover 6, the thickness of the entire baby electronic scale can be reduced.

[0045] Preferably, combined Figure 3 and Figure 5 As shown, the rectangular area surrounded by the first support part 11, the second support part 12 and the two connecting frames 13 is defined as the base center hole 17. A rectangular pallet center hole 21 is provided at the center of the pallet 2, and a protrusion 22 is provided around the edge of the pallet center hole 21. The protrusion 22 extends downward into the base center hole 17, and there is a small gap between the side wall of the protrusion 22 and the side wall of the base center hole 17. In this way, when the pallet 2 is assembled with the base 1, the pallet 2 can be effectively positioned, which is convenient for the alignment of the screw holes and can also play a role in limiting the position of the pallet 2.

[0046] like Figure 6-Figure 9As shown, an electric control box 8 is also provided in the first installation slot 111 . A circuit board can be provided in the electric control box 8 . The circuit board is used to collect detection signals of the two weighing sensors 3 , and transmit the two detection signals to a display or control device after fusion.

[0047] Notches 81 are provided on the opposite side walls of the electric control box 8 , and a plug plate 82 is provided in the notch 81 . The plug plate 82 is detachably connected to the electric control box 8 , and a third wire-passing hole 83 is formed between the bottom of the plug plate 82 and the electric control box 8 .

[0048] The electric control box 8 includes a bottom plate that fits with the bottom of the first mounting groove 111 and a panel that is vertically connected to the bottom plate. A rectangular notch 81 is provided on two opposite panels. A semicircular groove is provided at the bottom of the plug-in plate 82. A step structure is provided on both vertical sides of the plug-in plate 82. The plug-in plate 82 can be plugged into the electric control box 8 by facing downward with the side walls of the notch 81 on both sides, so that the plug-in plate 82 and the electric control box 8 have an interference fit. At this time, a third wire hole 83 is formed between the groove at the bottom of the plug-in plate 82 and the bottom plate of the electric control box 8. The signal line of the weighing sensor 3 can be introduced into the circuit board in the electric control box 8 through a third wire hole 83 of the electric control box 8, and the output line of the circuit board can be led out of the electric control box 8 through another third wire hole 83 of the electric control box 8.

[0049] The side wall of the first mounting groove 111 is provided with a fourth wire hole 14, which is a through hole. The outgoing wires of the circuit board led out of the electric control box 8 can be led out of the base 1 through the fourth wire hole 14 and then connected to the display or control device of the medical device.

[0050] Preferably, a first wire hole 51 is provided on the top of the support platform 5, and a second wire hole 52 is provided on the side wall of the support platform 5. The first wire hole 51 is connected to the clearance cavity between the support platform 5 and the bottom of the first mounting groove 111 / the second mounting groove 121, and the second wire hole 52 is also connected to the clearance cavity. The signal line led out from the end of the balance beam sensor first enters the first wire hole 51, passes through the clearance cavity, and then leads out from the second wire hole 52, thereby protecting the lead end of the balance beam sensor from interference or pressure from other components as much as possible.

[0051] Preferably, the connecting frame 13 is provided with a third mounting groove 131, the notch of the third mounting groove 131 faces upward, and the third mounting groove 131 runs from one end to the other end of the connecting frame 13. The connection points of the first supporting portion 11 and the second supporting portion 12 with the connecting frame 13 are both provided with notches for the connecting frame 13 to overlap, and the third mounting groove 131 is connected with the first mounting groove 111 and the second mounting groove 121.

[0052] A wire rack 15 is provided in the third mounting groove 131. The wire rack 15 includes a first flat plate, a second flat plate and a vertical plate. The first flat plate and the second flat plate are parallel to each other, and the vertical plate is perpendicular to the bottom of the third mounting groove 131, and is vertically connected to both the first flat plate and the second flat plate. Among them, the first flat plate fits with the bottom of the third mounting groove 131, and the edge of the first flat plate fits with the groove wall on one side of the third mounting groove 131, and the edge of the second flat plate fits with the groove wall on the other side of the third mounting groove 131, so that a wire passage 16 is formed between the second flat plate of the wire rack 15 and the bottom of the third mounting groove 131. The main function of the wire passage 16 is to facilitate the routing of the signal line of the weighing sensor 3 in the second mounting groove 121 to the electric control box 8, and to protect the cable from interference and pressure from other components.

[0053] In this embodiment, the wiring structure is reasonable. The signal line led out from the end of the weighing sensor 3 passes through the first wire hole 51, the second wire hole 52, and then passes through the wire channel 16 (the signal line of the weighing sensor 3 in the first installation groove 111 does not pass through the wire channel 16) and a third wire hole 83 to enter the electric control box 8 and connect to the circuit board. The cable led out from the circuit board passes through another third wire hole 83 to lead out of the electric control box 8 and then through the fourth wire hole 14 to the outside of the base 1. During the entire wiring process, the cables are in a protected state, which is convenient for the integration of the baby electronic scale of this embodiment with other devices, and also ensures that the cables are not interfered with, so that the weighing accuracy is higher and the cable life is longer.

[0054] Although the disclosure is disclosed as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the present invention.
