Description

Technical Field

[0001] The utility model relates to an electronic scale, in particular to a waterproof electronic scale instrument panel. Background Art

[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] Before an electronic scale is put into use, it is generally necessary to calibrate the range and other aspects of the scale by a formal department. Therefore, a switch for calibration is generally required to be provided on the existing electronic scale.

[0004] Existing calibration switches are typically installed on the instrument panel of electronic scales. Considering the safety of the calibration switch, and also considering waterproof requirements, installing the calibration switch requires opening a through-hole in the instrument panel housing. This hole, when opened for calibration, can cause liquid to leak into the scale body. After calibration, the calibration switch hole must be sealed, increasing the complexity of the operation. Furthermore, since the scale is not an integrated design, the sealed hole still has the potential for liquid leakage.

[0005] There is currently no waterproof electronic scale instrument panel that can solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a waterproof electronic scale instrument panel, which can be installed in an integrated magnet slot through a magnet and cooperate with a Hall switch to achieve improved waterproof performance.

[0007] In order to achieve the above-mentioned object, the present invention discloses the following waterproof electronic scale instrument panel; the waterproof electronic scale instrument panel comprises:

[0008] Bracket;

[0009] An instrument panel, the instrument panel comprising a housing and a control unit, the housing having a first surface and a second surface disposed opposite each other, the control unit being disposed between the first surface and the second surface of the housing, the second surface of the housing being connected to the bracket, the second surface of the housing being bent away from the first surface of the housing and protruding with a waterproof layer;

[0010] The waterproof layer has a magnet slot recessed into the interior of the instrument panel, the magnet slot is used to accommodate a magnet, and a Hall switch is installed on the side of the magnet slot facing the interior of the instrument panel, and the Hall switch is connected to the control unit signal; so that when the magnet is installed in the magnet slot, the Hall switch can sense the presence of the magnet and send a signal to the control unit to control the control unit; the magnet slot and the waterproof layer are set as an integrated structure.

[0011] Furthermore, the instrument panel also includes a cover plate, the size of the cover plate matches the slot size of the magnet slot, and the cover plate is snap-fitted with the magnet slot so that when the magnet is installed in the magnet slot, the cover plate can press and fix the magnet in the magnet slot.

[0012] Furthermore, after the Hall switch can sense the presence of the magnet, an operator can calibrate the control unit.

[0013] Furthermore, there are multiple combinations of the magnet slots, the magnets, and the Hall switches, and the multiple combinations of the magnet slots, the magnets, and the Hall switches are arranged at intervals on the waterproof layer.

[0014] Furthermore, a combination of a plurality of magnet slots, the magnets and the Hall switches is arranged at the waterproof layer position on the bottom edge.

[0015] Furthermore, the instrument panel further includes a display device, which is mounted on the first surface of the housing and is electrically connected to the control unit.

[0016] Furthermore, the instrument panel is rotatably connected to the bracket, and both ends of the bracket are connected to two opposite sides of the waterproof layer that avoid the magnet slot.

[0017] By means of the above technical solution, the beneficial effects of the present invention are as follows:

[0018] The waterproof electronic scale instrument panel of the present invention can be installed in the integrated magnet slot by means of a magnet when calibration is required, and can be operated in conjunction with the Hall switch to control the control unit, making operation easier and eliminating the need for frequent disassembly and installation of the calibration switch. Since only magnetic force is required to enable the Hall switch to be opened and closed, the waterproof layer of the outer shell can be an integrated structure, achieving complete sealing, thereby greatly improving the waterproof performance of the instrument panel.

Obviously, the described embodiments are only part of the embodiments of this specification, not all of them.

The following implementation methods will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention.

[0026] It should be understood that although terms such as "first," "second," and "third" may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. In addition, the term "or" as used herein may include any one or more combinations of the associated listed items, as appropriate.

[0027] See Figure 1-2 , is a waterproof electronic scale instrument panel of this embodiment; wherein the waterproof electronic scale instrument panel includes:

[0028] Bracket 1;

[0029] The instrument panel includes a housing 2 and a control unit. The housing 2 has a first surface 21 and a second surface 22 that are opposite to each other. The control unit is located between the first surface 21 and the second surface 22 of the housing. The second surface 22 of the housing 2 is connected to the bracket 1. The second surface 22 of the housing 2 is bent away from the first surface 21 of the housing 2 and has a protruding waterproof layer 221.

[0030] Among them, the waterproof layer 221 has a magnet slot 2211 recessed into the interior of the instrument panel, the magnet slot 2211 is used to accommodate the magnet 3, and a Hall switch 4 is installed on the side of the magnet slot 2211 facing the interior of the instrument panel, and the Hall switch 4 is connected to the control unit signal; so that when the magnet 3 is installed in the magnet slot 2211, the Hall switch 4 can sense the presence of the magnet 3 and send a signal to the control unit to control the control unit; the magnet slot 2211 and the waterproof layer 221 are set to an integrated structure.

[0031] Through the above structure, when the electronic scale needs to be calibrated during use, the operator first needs to keep the magnet slot 2211 of the housing 2 in the open state, and then install the magnet 3 into the magnet slot 2211 so that the magnet 3 is close to the Hall switch 4. At this time, the Hall switch 4 senses the attraction of the magnet 3, the Hall switch 4 is activated and transmits the signal to the control unit connected to the signal. Then, the control unit unlocks the calibration authority for the operator, and the operator can continue to adjust the electronic scale of this device. After the adjustment is completed, the operator can remove the magnet 3 from the magnet slot 2211 of the housing 2 again. At this time, the Hall switch 4 is separated from the magnet 3 and is in the closed state. The control unit connected to the signal receives the signal that the Hall switch 4 is closed. At this time, the system is locked, and the operator cannot calibrate the electronic scale from the outside, thus completing the entire calibration process.

[0032] During the aforementioned use, the Hall switch 4 and the magnet 3 are used to activate or deactivate the control unit. Direct contact between the Hall switch 4 and the magnet 3 is not required. Therefore, the magnet slot 2211 itself maintains integrity, eliminating the need for additional slots or holes. Furthermore, in this embodiment, the magnet slot 2211 and the waterproof layer 221 are formed into an integrated structure. Specifically, the second surface 22 of the housing 2 is configured as an integrated casting surface, providing excellent waterproofing. This minimizes the risk of liquid leakage before and after the calibration process, compared to existing designs that require slots or holes at the calibration switch location. Furthermore, during the aforementioned use, the corresponding switch control can be achieved simply by placing the magnet 3 in or removing it from the magnet slot 2211. This significantly improves operational efficiency compared to existing operations that require tools to unscrew fasteners.

[0033] Further, see Figure 1The instrument panel also includes a cover plate 5. The size of the cover plate 5 matches the size of the slot of the magnet slot 2211, and the cover plate 5 is snap-fitted with the magnet slot 2211 so that when the magnet 3 is installed in the magnet slot 2211, the cover plate 5 can firmly secure the magnet 3 in the magnet slot 2211. Specifically, after the magnet 3 is installed in the magnet slot 2211, the cover plate 5 can be installed and snap-fitted to the slot of the magnet slot 2211 to achieve contact between the magnet 3 and the inner side of the cover plate 5, thereby preventing the magnet 3 from falling out and affecting the signal connection between the magnet 3 and the Hall switch 4. After the magnet 3 is removed, the cover plate 5 can be installed back in place, which can further enhance the waterproof performance of the magnet slot 2211.

[0034] Furthermore, there are multiple combinations of magnet slots 2211, magnets 3, and Hall switches 4, and these combinations are arranged in intervals on the waterproof layer 221. At the same time, the combination of multiple magnet slots 2211, magnets 3, and Hall switches 4 is located at the bottom edge of the waterproof layer 221. Specifically, the second surface 22 mounted on the bracket 1 has a certain forward tilt angle, making the combination of multiple magnet slots 2211, magnets 3, and Hall switches 4 at the bottom easier for operators to operate and handle, and allowing most of the structure to be located at the bottom of the instrument panel, making the center of gravity of the instrument panel more stable. With the above structure, during use, in order to enhance safety, a better switch and trigger mechanism is achieved through the combination of multiple magnets 3 and Hall switches 4. For example, in one embodiment, there are four magnet slots 2211, magnets 3, and Hall switches 4. The operator must simultaneously insert and install all four magnets 3 into the corresponding magnet slots 2211 so that all four Hall switches 4 receive magnetic signals. The control unit can only unlock the correction permission after determining that all four are connected. That is to say, as long as one magnet 3 is not installed in place, calibration cannot be achieved, which greatly enhances the safety of the electronic scale of this embodiment.

[0035] Of course, the number of combinations of magnet slots 2211, magnets 3 and Hall switches 4 can be increased or decreased as appropriate according to the requirements of safety and space layout.

[0036] Further, if Figure 1 As shown, the instrument panel further includes a display device 6, which is mounted on the first surface 21 of the housing 2 and is electrically connected to the control unit. The display unit allows the information of the electronic scale of this embodiment to be intuitively displayed toward the operator.

[0037] Furthermore, the instrument panel is rotatably connected to the bracket 1, and both ends of the bracket 1 are connected to two relatively arranged sides of the waterproof layer 221 to avoid the magnet slot 2211. Specifically, the shell 2 in this embodiment is configured to be approximately a rectangular body, and the waterproof layer 221 protruding behind the shell 2 is also approximately a rectangular body. The bracket 1 is clamped at the left and right ends of the rectangular body of the protruding waterproof layer 221, and the combination of the magnet slot 2211, the magnet 3 and the Hall switch 4 is arranged at the bottom position of the rectangular body of the waterproof layer 221. When the angle of the display device 6 needs to be adjusted, it is only necessary to rotate the shell 2 around the two contact points between the bracket 1 and the waterproof layer 221 to achieve the angle adjustment of the display device 6, maximize the function of the display device 6, and also facilitate the disassembly and assembly of the magnet 3.
