Description

Technical Field

[0001] The utility model relates to the technical field of weighing equipment, in particular to a scale foot device and an electronic scale. Background Art

[0002] Currently, the electronic scales on the market usually adopt mountain-shaped or cross-shaped sensors. The foot cover and the sensor are in surface contact, and the foot pad is designed as a flat surface. When the mountain-shaped or cross-shaped sensor measures the output, it is measured perpendicular to the strain area. Once the user stands off-center when getting on the scale, a torsional angle will be generated in the strain area of the sensor, resulting in a low measurement accuracy of the electronic scale.

[0003] Therefore, how to improve the measurement accuracy of the electronic scale is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a scale foot device, which can effectively improve its measurement accuracy.

[0005] Another purpose of the utility model is to provide an electronic scale.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A scale foot device includes a foot pad, a foot cover and a gravity sensor. One side of the foot cover is in contact with the gravity sensor, and the other side is in contact with the foot pad. A support portion is provided on the foot pad, and the area of the support surface of the support portion is smaller than the area of the foot pad.

[0008] Optionally, the support surface is a spherical surface or a flat surface; the surface of the foot pad in contact with the ground is a flat surface or a spherical surface.

[0009] Optionally, a protrusion is provided on the foot cover, and a groove matching the protrusion is provided on the foot pad.

[0010] Optionally, the protrusion is a cylindrical protrusion, the groove is a circular groove imitating the shape of the protrusion, and the diameter of the groove is larger than the diameter of the protrusion;

[0011] The protrusion includes a fixed end and a contact end. The fixed end is provided on the foot cover, and the contact end is used to contact the groove.

[0012] Optionally, the end surface of the contact end is a flat structure, and the part of the groove in contact with the contact end is a flat structure.

[0013] Optionally, a first rounded corner is provided on the contact end, a second rounded corner is provided on the groove, and the radius of curvature of the second rounded corner is smaller than the radius of curvature of the first rounded corner.

[0014] Optionally, the end face of the contact end is a spherical surface, and the part where the groove contacts the protrusion is a spherical surface.

[0015] Optionally, the weighing foot device further includes a gasket, and the foot pad is provided with a groove for installing the gasket;

[0016] The gasket is made of plastic or metal.

[0017] Optionally, the weighing foot device further includes an adhesive, and the gasket and the foot pad are bonded by the adhesive.

[0018] An electronic scale includes the weighing foot device as described in any one of the above, and there are multiple such weighing foot devices;

[0019] It further includes a front shell and a bottom shell. The front shell and the bottom shell form an installation space, and the bottom shell is further provided with a through hole for the weighing foot device to expose.

[0020] It can be seen from the above technical solutions that when gravity acts on the gravity sensor, the gravity sensor sequentially transmits the gravity to the foot cover and the foot pad. Since the foot pad is provided with a support portion, and the area of the support surface of the support portion is smaller than the area of the foot pad, when the user steps on the scale, the torsional angle of the strain area of the gravity sensor will be reduced. Therefore, the measurement deviation problem caused by the torsional angle of the strain area of the gravity sensor can be greatly reduced, thereby improving the measurement accuracy of the electronic scale.

[0029] In view of this, the core of the present invention lies in providing a weighing foot device, which can effectively improve its measurement accuracy.

[0030] Another core of the present invention also lies in providing an electronic scale.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Please refer to Figures 1 to 5 .

[0032] The weighing foot device disclosed in the embodiments of the present invention includes a foot pad 100, a foot cover 200 and a gravity sensor 500. Among them, one side of the foot cover 200 is in contact with the gravity sensor, and the other side is in contact with the foot pad 100. A support portion is provided on the foot pad 100, and the area of the support surface 102 of the support portion is smaller than the area of the foot pad 100.

[0033] When gravity acts on the gravity sensor 500, the gravity sensor 500 sequentially transmits the gravity to the foot cover 200 and the foot pad 100. Since a support portion is provided on the foot pad 100 and the area of the support surface 102 of the support portion is smaller than the area of the foot pad 100, when the user steps on the scale, the torsion angle of the strain area of the gravity sensor 500 will be reduced. Therefore, the measurement deviation problem caused by the torsion angle of the strain area of the gravity sensor 500 can be greatly reduced, thereby improving the measurement accuracy of the electronic scale.

[0034] Among them, the support surface 102 can be a spherical surface or a flat surface. Whether it is a spherical surface or a flat surface, the contact area between the support portion 100 and the ground can be reduced.

[0035] Among them, the surface of the foot pad 100 in contact with the ground can be a flat surface or a spherical surface.

[0036] The embodiments of the present utility model do not limit the specific structures of the foot mat 100 and the foot cover 200, and any structure that meets the usage requirements of the present utility model is within the protection scope of the present utility model.

[0037] As the first specific embodiment of the present utility model, please refer to Figure 1 and Figure 2 In the foot cover 200 disclosed in the embodiments of the present utility model, a protrusion 201 is provided, and a groove 101 matching the protrusion 201 is provided on the foot mat 100. When assembling the foot weighing device, the protrusion 201 can be placed in the groove 101 to complete the assembly of the two.

[0038] The embodiments of the present utility model do not limit the specific shape and structure of the protrusion 201, as long as the assembly of the foot mat 100 and the foot cover 200 can be achieved.

[0039] As a preferred embodiment, the protrusion 201 disclosed in the embodiments of the present utility model is a cylindrical protrusion, and the groove 101 is a circular groove that imitates the shape of the protrusion 201. Among them, the diameter of the groove 101 is greater than the diameter of the protrusion 201.

[0040] It should be noted that the protrusion 201 includes a fixed end and a contact end. Among them, the fixed end is provided on the foot cover 200, and the contact end is used to contact the groove 101.

[0041] Among them, the end face of the contact end can be set as a planar structure. Correspondingly, the part of the groove in contact with the contact end also needs to be set as a planar structure. With such a setting, effective cooperation between the foot mat 100 and the foot cover 200 can be achieved.

[0042] As a further embodiment, a first rounded corner is provided on the contact end disclosed in the embodiments of the present utility model, and a second rounded corner is provided on the groove. Among them, the radius of curvature of the second rounded corner is smaller than the radius of curvature of the first rounded corner. With such a setting, exhaust can be better carried out when the foot cover 200 and the foot mat 100 are assembled.

[0043] Of course, the end face of the contact end can also be set as a spherical surface. Correspondingly, the part of the groove in contact with the protrusion also needs to be set as a spherical surface. With such a setting, effective cooperation between the foot mat 100 and the foot cover 200 can be achieved.

[0044] For details, please refer to Figure 1 , the first arm 501 and the second arm 502 of the gravity sensor 500 are two arm parts of the strain area. If the electronic scale is not placed horizontally, or when the scale plate is tilted due to the user stepping on it unevenly, the relative angles of the first arm 501 and the second arm 502 with the horizontal plane and the vertical plane may be different. At this time, it is understood that the strain area of the gravity sensor has undergone torsion.

[0045] Since the first arm 501 and the second arm 502 are respectively fixedly connected to the foot cover 200 through screw structures, when the strain area twists, correspondingly, the foot cover 200 cannot remain horizontal, that is, it tilts relative to the horizontal plane.

[0046] When the contact end of the protrusion 201 and the support surface 102 are both flat surfaces, and the area of the support surface 102 is small, that is, the area of the contact end is small, the angle of mutual displacement between the contact end and the support surface 102 is small, that is, the fitting angle / offset angle between the foot cover 200 and the foot pad 100 will be limited to a small range, so as to limit or partially correct the torsion of the strain area of the gravity sensor 500; at the same time, the contact surface between the foot pad 100 and the ground is spherical or curved, which can cause partial or complete cancellation of the axial torsion of the foot cover 200 and the foot pad 100. Therefore, the precision error caused by the torsion of the strain area is reduced.

[0047] As the second embodiment of the present invention, please refer to Figure 3 and Figure 4 , the weighing foot device disclosed in the embodiment of the present invention further includes a gasket 300, wherein a groove 101 for installing the gasket 300 is provided on the foot pad 100. When assembling the electronic scale, the gasket 300 can be placed in the groove 101, and at this time, one side of the gasket 300 is in contact with the gravity sensor 500. When the user gets on the scale, the gravity can be sequentially transmitted from the gravity sensor 500 to the foot cover 200, the gasket 300, and the foot pad 100.

[0048] The embodiment of the present invention does not limit the specific material of the gasket 300. The gasket 300 can be made of plastic material, can be made of metal material, and of course can also be made of other materials, as long as the material that meets the use requirements of the present invention is within the protection scope of the present invention.

[0049] In order to prevent the gasket 300 from falling off the groove 101, the weighing foot device disclosed in the embodiment of the present invention further includes an adhesive 400, wherein the gasket 300 and the foot pad 100 are bonded through the adhesive 400.

[0050] Of course, the side wall of the groove 101 of the foot pad 100 and the side wall of the gasket 300 can also be connected by an interference fit in part or in whole.

[0051] In order to improve the connection strength between the foot pad 100 and the foot cover 200, an installation groove 202 for installing the foot pad 100 is provided on the foot cover 200 disclosed in the embodiment of the present invention, wherein the foot pad 100 is installed in the installation groove 202. With this setting, the foot pad 100 is not easily loosened from the foot cover 200.

[0052] It should be noted that the supporting surface 102 is the bottom surface of the groove 101. In the first embodiment, it is the surface that contacts the top surface of the protrusion 201. In the second embodiment, it is the surface that contacts the gasket 300. For details, please refer to Figure 5 .

[0053] The embodiment of the present utility model also discloses an electronic scale, which includes the scale foot device disclosed in any one of the above embodiments, and among them, there are multiple scale foot devices.

[0054] It should be noted that the electronic scale disclosed in the embodiment of the present utility model further includes a front shell and a bottom shell 800. Among them, the front shell and the bottom shell 800 form an installation space, and the bottom shell 800 is also provided with a through hole for the scale foot device to expose.

[0055] Among them, the scale foot devices can be distributed at any position on the bottom shell 800. As a preference, a scale foot device is provided at the center of the bottom shell 800 disclosed in the embodiment of the present utility model, and at least 2 scale foot devices are provided at the edge of the bottom shell 800. Among them, the scale foot device provided at the center of the bottom shell 800 has a preset distance from the ground. When the electronic scale is loaded, the scale foot device placed at the center of the bottom shell 800 can touch the ground. When the electronic scale is unloaded, the scale foot device can return to the initial state.

[0056] It should be noted that based on the principle that three points determine a plane, the more the number of scale foot devices is set, the greater the probability of the electronic scale being uneven. However, in the embodiment of the present utility model, since the scale foot device provided at the center of the bottom shell 800 has a preset distance from the ground when not loaded, that is, it does not contact the ground, the probability of the electronic scale being uneven will be reduced.

[0057] When the electronic scale is loaded, the scale foot device provided at the center of the bottom shell 800 will contact the ground. Since a gravity sensor is provided in the scale foot device, the increase in the number of gravity sensors 500 will further improve the measurement accuracy of the electronic scale.

[0058] In the prior art, the bottom end surface of the foot pad 100 is generally a smooth surface, and when unloading, there will be a "pop" sound.

[0059] As a further embodiment, the bottom end surface of the foot pad 100 of the scale foot device disclosed in the embodiment of the present utility model is a matte surface, and the setting of the matte surface can solve the problem of the sound when unloading.

[0060] It should be noted that the bottom end surface of the foot pad 100 is the surface that contacts the ground.

[0061] As a further embodiment, the scale foot device disclosed in the embodiment of the present utility model is set to 5, including one at the center of the bottom shell 800 and 4 at the edge of the bottom shell 800.

[0062] It should be noted that the gravity sensor 500 disclosed in the embodiments of the present utility model includes a sensor body, a sensor seat 700, and a sensor cover 600. The sensor body is installed on the sensor seat 700, and the sensor cover 600 is disposed on the sensor body. The three are combined into a whole.

[0063] Among them, the gravity sensor 500 can be a mountain-shaped sensor, a cross-shaped sensor, or a sensor with other structures. Those skilled in the art select different installation methods according to the different characteristics of different gravity sensors 500.

[0064] In the first embodiment of the present utility model, the gravity sensor 500 is a cross-shaped sensor. At this time, bolt holes are opened in the installation groove of the foot cover 200, and the foot cover 200 and the bottom shell 800 are fixed by bolts. The gravity sensor 500 is clamped between the foot cover 200 and the bottom shell 800.

[0065] In the second embodiment of the present utility model, the gravity sensor 500 is a mountain-shaped sensor. At this time, the mountain-shaped sensor 500 is installed on the sensor seat 700, the foot cover 200 is pressed on the mountain-shaped sensor, and then it is fixed by the sensor cover 600.

[0066] The embodiments of the present utility model have conducted multiple tests on the use effect of the electronic scale, as shown in the following table. The results show that compared with the prior art, when conducting multiple consecutive tests within a unit time (for example, 5 complete tests are completed in 5 minutes, and it is considered that the true human body weight variation is 0 during this period), the passing rate of the true human consistency is relatively high, that is, the measurement accuracy of the electronic scale is greatly improved.
