Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of intelligent sanitary ware, and in particular to a gear box fixing device of an intelligent toilet cover, an intelligent toilet cover and an intelligent toilet. Background Art
[0002] Compared with ordinary toilets, smart toilets have more functions, such as automatic lid opening, night light lighting, lower body cleaning, silent seating, etc.
[0003] A conventional smart toilet lid usually has a housing and a gear box disposed on the housing, and the gear box drives the lid or seat to flip through a flat shaft.
[0004] However, the traditional scheme is to press the outer shell of the gearbox directly onto the housing through various assembly methods. Since there will be certain tolerances in the actual manufacturing of the gearbox and the housing, and there will also be certain assembly tolerances when assembling the gearbox to the housing, this will cause the flat shaft of the gearbox and the shaft hole on the seat ring or the flap to be misaligned, so that the drive shaft encounters greater resistance when driving the flap or the seat ring to rotate, which in turn causes the gear assembly in the gearbox that is connected to the flat shaft to be affected, and even the gears may burst, resulting in a shortened service life of the gearbox.
[0005] BACKGROUND OF THE PRESENT APPLICATION The above information disclosed is only used to understand the background of the concept of the present application, and does not indicate or imply that it contains information of the prior art. Utility Model Content
[0006] Based on this, it is necessary to provide a gear box fixing device for a smart toilet cover, a smart toilet cover and a smart toilet to address the above problems.
[0007] A gear box fixing device for an intelligent toilet cover, comprising:
[0008] A housing, wherein the housing is provided with a positioning groove and a through hole opened at the bottom of the positioning groove;
[0009] A gear box, the gear box comprising a box body, a gear assembly and a drive shaft arranged on the housing, the gear assembly being arranged in the box body, a positioning protrusion matched with the positioning groove being arranged on the side of the box body facing the positioning groove, the box body being inserted into the positioning groove through the positioning protrusion to be positioned and connected with the housing, the drive shaft being passed through the positioning protrusion, one end of the drive shaft being located in the box body and being transmission-connected with the gear assembly, and the other end of the drive shaft passing through the through hole to be transmission-connected with the flip cover or the seat ring;
[0010] A fixing bracket, wherein the fixing bracket cover is arranged on a side of the gear box facing away from the shell, and the fixing bracket is detachably connected to the shell to achieve the fixing of the gear box and the shell.
[0011] The gearbox fixing device of the above-mentioned smart toilet lid of the present application can at least achieve the following beneficial effects: a positioning groove is provided on the housing, and a positioning protrusion is provided on the housing of the gearbox.

On this basis, the present application does not pursue the traditional scheme of excessively pressing the housing of the gearbox on the housing to achieve reliable connection between the two, but adds a fixing bracket, which is covered on the side of the gearbox facing away from the housing, and the fixing bracket is detachably connected to the housing to achieve the fixing of the gearbox and the housing, without excessively pressing the gearbox on the housing, and can achieve reliable connection between the gearbox and the housing on the premise that the drive shaft of the gearbox and the shaft hole on the flip cover or the seat ring maintain extremely high coaxiality, which not only avoids the excessive rotation resistance of the drive shaft due to insufficient coaxiality, but also reduces the risk of gear explosion in the gear assembly, and reduces the requirements for the manufacturing accuracy and assembly accuracy of the gearbox and the housing.
[0012] In one embodiment, the fixing bracket includes a main body and a first extension portion and a second extension portion respectively connected to both sides of the main body, the first extension portion is set at an angle to the main body, the second extension portion is set at an angle to the main body, the first extension portion, the main body and the second extension portion are combined to form a clamping opening adapted to the box body, the clamping opening is used to clamp the box body, the main body abuts against a side of the box body facing away from the shell, the first extension portion and the second extension portion respectively abut against both sides of the box body, and the first extension portion is detachably connected to the shell to fix the box body on the shell.

The gear box 300 and the shell 100 can be reliably connected on the premise that the drive shaft 330 of the gear box 300 and the axial hole on the flip cover or the seat ring 200 maintain extremely high coaxiality. This not only avoids the excessive rotational resistance of the drive shaft 330 due to insufficient coaxiality, but also reduces the risk of gear bursting in the gear assembly, and reduces the requirements for the manufacturing accuracy and assembly accuracy of the gear box 300 and the shell 100.
[0045] In addition, the present application also provides a smart toilet, which includes a toilet seat and a smart toilet cover 10 as described in any of the above embodiments, and the smart toilet cover 10 is covered on the toilet seat.
