AI Technical Summary
Existing electric toilet lid flippers require motors with high torque, resulting in excessively high costs.
The system employs a spring-assisted structure, which works in conjunction with a spring box assembly and a motor to provide additional torque through a torsion spring to assist in the flipping of the cover, thereby reducing the motor torque requirements.
It enables the cover plate to be effectively flipped and closed with a smaller motor torque, thus reducing motor costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of toilets, and in particular to an electric flip-top structure with spring assistance. Background Technology
[0002] Currently, electric toilet seat covers on the market require motors with high torque to function, resulting in excessively high costs. Utility Model Content
[0003] To solve the above problems, this technical solution provides an electric flip cover structure with spring assistance.
[0004] To achieve the above objectives, the technical solution is as follows:
[0005] A spring-assisted electric flip cover structure includes a housing and a cover plate rotatably mounted on the housing. The housing is provided with a rotating groove, and the cover plate is provided with a rotating part extending into the rotating groove.
[0006] It also includes a spring box assembly disposed within the housing, which includes a first spring box, a first rotating shaft extending into the rotating part is provided inside the first spring box, a first torsion spring is sleeved on the first rotating shaft, and a first spring box cover connected to the first spring box.
[0007] It also includes a motor disposed within the housing for driving the cover plate to flip.
[0008] In some embodiments, the rotating part is provided in two parts, one of which is connected to a second rotating shaft. The second rotating shaft is fitted with a second torsion spring. The second rotating shaft is installed in a second spring box located inside the housing. The end of the second spring box is provided with a second spring box cover.
[0009] In some embodiments, the first spring box cover is detachably mounted on the first spring box via a snap-fit mechanism.
[0010] In some embodiments, one end of the first torsion spring is vertically inserted into the first spring box, and the other end is horizontally inserted into the first spring box.
[0011] The beneficial effects of this application are:
[0012] This application uses a torsion spring to increase the torque, so that the motor can drive the cover plate to the designated position even with a smaller torque. Attached Figure Description
[0013] To more clearly illustrate the technical solutions in the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.
[0014] Figure 1This is a cross-sectional structural schematic diagram of an embodiment of the present utility model;
[0015] Figure 2 This is an exploded structural diagram of an embodiment of the present invention. Detailed Implementation
[0016] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0017] Please refer to Figure 1-2 As shown, an electric flip cover structure with spring assistance includes a housing 1 and a cover plate 2 rotatably mounted on the housing 1. The housing 1 is provided with a rotating groove 3, and the cover plate 2 is provided with a rotating part 4 extending into the rotating groove 3.
[0018] It also includes a spring box assembly disposed within the housing 1, which includes a first spring box 5, a first rotating shaft 6 extending into the rotating part 4 within the first spring box 5, a first torsion spring 7 sleeved on the first rotating shaft 6, and a first spring box cover 8 connected to the first spring box 5.
[0019] It also includes a motor 9 disposed inside the housing 1 for driving the cover plate 2 to flip.
[0020] The cover is connected to the pivot at its maximum open angle. When the cover angle exceeds its own equilibrium angle, it flips downwards under its own weight. The rotational force is transmitted to the torsion spring through the pivot, and the torsion spring's restoring force counteracts the weight of the cover falling freely (adjusting the spring force so that the cover closes to the designated position and balances with the spring's restoring force). At this time, the motor only needs to use a small amount of torque to break the balance between the torsion spring's restoring force and the cover's own weight so that the motor can easily flip the cover. When the cover is open, the motor only needs to use a small amount of torque to make the cover angle exceed its own equilibrium point, and the cover closes to the designated position under its own weight.
[0021] In this embodiment, there are two rotating parts 4. One rotating part 4 is connected to a second rotating shaft 10. The second rotating shaft 10 is fitted with a second torsion spring 11. The second rotating shaft 10 is installed in a second spring box 12 located inside the housing 1. The end of the second spring box 12 is provided with a second spring box cover 13. Since there are two rotating parts, each rotating part is provided with a spring box to provide torque.
[0022] In this embodiment, the first spring box cover 8 is detachably mounted on the first spring box 5 via a snap fastener, allowing for quick assembly of the box body and the cover body.
[0023] In this embodiment, one end of the first torsion spring 7 is vertically inserted into the first spring box 5, and the other end is horizontally inserted into the first spring box 5.
[0024] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
