Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, and in particular relates to an electric sit-up assist device. Background Technology

[0002] Sit-ups are a common form of exercise. To make it easier for people to do sit-ups independently, many types of sit-up aids have appeared on the market.

[0003] For example, Chinese utility model patent CN202021134488.4, entitled "Suction Cup Type Sit-up Assist," discloses a suction cup type sit-up assist, including a base and a support mechanism. The base is located below the support mechanism, and a suction cup is provided below the base. A connecting post is provided in the middle of the suction cup, and the connecting post passes through the base to the top. An insertion hole is provided on the connecting post, and an insertion tube is provided on the base. A slot is provided below the insertion tube, and a trigger is provided in the slot. The suction cup is characterized by having a connecting post in the middle, with an iron part embedded in the connecting post. The suction cup includes a frame and a base, which are fixedly connected. A pull tab is provided on the suction cup, and the pull tab is not on the same horizontal plane as the suction cup.

[0004] However, the aforementioned patent requires manual pressing of a trigger to make the bottom suction cup adhere to the ground before starting the movement. When the movement ends, the pull tab on one side of the suction cup is lifted to allow air to enter the suction cup, thus separating it from the ground. The overall operation is rather cumbersome, and it is prone to air leakage as the exercise time increases. Furthermore, the suction power is relatively weak. Therefore, an electric sit-up assist device is needed to solve the above problems. Utility Model Content

The cover is detachably installed on the upper end of the mounting part to close the inner cavity.

[0010] Furthermore, the main control board is equipped with control buttons and a charging interface, and the cover is equipped with a pressing part corresponding to the control buttons.

[0011] Furthermore, the base is provided with an insertion tube, and the insertion tube is provided with several vertically arranged adjustment holes, and the insertion tube and the base are integrally formed.

[0012] Furthermore, the support mechanism includes an upper tube, a lower tube, and a telescopic rod. The telescopic rod is adjustablely disposed inside the insertion tube.

[0016] By using the above technical solution, compared with the prior art, this utility model has the following beneficial effects: An electronic control unit is installed on the base, and within the electronic control unit are an air pump motor, a main control board, an intake valve, a vent valve, and a battery assembly. The battery assembly powers the main control board, which is electrically connected to the air pump motor, the intake valve, and the vent valve. The intake valve and the air pump motor are connected via an air pipe, and the air inlet on the intake valve is connected to the adsorption space through a through hole in the electronic control unit. During movement, the base is placed on the ground, allowing the components located below the base to... The suction cup adheres to the ground, creating a sealed suction space between the ground and the suction cup.

[0028] like Figure 1-3 As shown: An electric sit-up assist device includes a base 1 and a support mechanism 2. The base 1 is located below the support mechanism 2. A suction cup 3 is provided below the base 1. The suction cup 3 and the bottom surface of the base 1 form an adsorption space. An electronic control unit 4 is provided on the base 1. The electronic control unit 4 contains an air pump motor 5 and a main control board 6 electrically connected to the air pump motor 5. The air pump motor 5 has an air intake valve 7 connected to its suction end. An air intake port connected to the adsorption space is provided on one side of the air intake valve 7. The air intake valve 7 is electrically connected to the main control board 6.

[0029] In this embodiment, the air pump motor 5 is a vacuum pump. The electrical control unit 4 has several fixed columns. The main control board 6 is fixed on the fixed columns by bolts. The suction end of the air pump motor 5 is connected to the upper air inlet of the suction valve 7 through an air pipe to form an air passage. The end of the suction valve 7 away from the upper air inlet is the lower air inlet, which is connected to the adsorption space. The suction valve 7 is a miniature solenoid valve. The suction valve 7 is electrically connected to the main control board 6. When the suction valve 7 is energized, air flows through both the upper and lower air inlets, and the suction valve 7 is in the open state. When it is not energized, air does not flow through the upper and lower air inlets, and the suction valve 7 is in the closed state. When the air pump motor 5 starts, the suction valve 7 is energized accordingly. At this time, the air in the adsorption space can be extracted to make it a vacuum chamber.

[0030] like Figure 2 As shown: The electronic control unit 4 is also equipped with a vent valve 8 and a battery assembly 9. Both the vent valve 8 and the battery assembly 9 are electrically connected to the main control board 6. One end of the vent valve 8 is provided with an air outlet, which is connected to the adsorption space. The end of the vent valve 8 away from the air outlet is provided with a vent, which is located in the inner cavity of the electronic control unit 4.

[0031] When the suction valve 7 is energized, the vent and outlet are connected, allowing external space to enter the vacuum chamber formed by the adsorption space through the vent and outlet, at which point the suction cup can detach from the ground.

[0032] like Figure 2-3 As shown: The bottom surface of the base 1 has two through holes that are connected to the electrical control unit 4. The air inlet of the suction valve 7 and the air outlet of the vent valve 8 are respectively set in the two through holes, and the through holes are provided with sealing elements that match the air inlet and the air outlet. By setting the sealing elements, the sealing performance of this device can be enhanced, thereby making the suction cup more attractive.

[0033] The electronic control unit 4 includes a mounting part 401 and a cover 402 integrally formed with the base 1. The mounting part 401 has an inner cavity. The air pump motor 5, main control board 6, air intake valve 7, air release valve 8 and battery assembly 9 are all installed in the inner cavity of the mounting part 401. The cover 402 is detachably installed on the upper end of the mounting part 401 to close the inner cavity.

[0034] like Figure 1-2As shown: The main control board 6 is equipped with control buttons and a charging interface 601. The cover 402 is equipped with a pressing part 403 corresponding to the control buttons. The charging interface 601 is electrically connected to the main control board 6. The electronic control unit 4 has a slot that matches the charging interface 601 for wired charging. In this embodiment, the charging interface 601 is a Type-C interface. The charging interface 601 can supply power to the battery assembly 9 in real time for easy use. The control buttons can control the start or stop of the air pump motor 5, the suction valve 7, and the vent valve 8, thereby making it easier to control the suction cup's adsorption and retrieval. Specifically, when the control button is pressed by clicking, the air pump motor 5 and the suction valve 7 will be started, thereby controlling the adsorption of the suction cup. When the suction cup is finished, the control button will be pressed by double-clicking to trigger the vent valve 8, completing the venting process, thereby allowing the suction cup to detach from the ground for easy retrieval.

[0035] like Figure 3 As shown: The base 1 is provided with a tube 101, and the tube 101 is provided with several vertically arranged adjustment holes 102. The tube 101 and the base 1 are integrally formed, and the integrally formed design can increase the overall strength of the base 1.

[0036] like Figure 1 As shown: The support mechanism 2 includes an upper tube 201, a lower tube 202, and a telescopic rod 203. The telescopic rod 203 is adjustablely installed inside the insertion tube 101. The telescopic rod 203 has a stop hole, which corresponds to the adjustment hole 102, and a fixing pin 10 is installed inside. The upper tube 201 is installed on both sides of the telescopic rod 203, and the lower tube 202 is installed on both sides of the insertion tube 101. By installing the telescopic rod 203, which can be moved up and down and adjusted, inside the insertion tube 101, the height of the telescopic rod 203 and the height of the upper tube 201 located on both sides of the telescopic rod 203 can be controlled. The fixing pin 10 and the stop hole are used to facilitate operation and adjustment. The height can be adjusted to suit different users or different usage situations.

[0037] like Figure 1 As shown: The telescopic rod 203 has an opening for the upper tube 201 to pass through, and the upper tube 201 has a sponge sleeve on both sides. The insertion tube 101 has an opening for the lower tube 202 to pass through, and the lower tube 202 has a sponge sleeve on both sides.

[0038] like Figure 3 As shown: The bottom surface of the base 1 is provided with a slot 103, and the suction cup 3 is provided with a protrusion that matches the slot 103. The suction cup 3 and the base 1 are detachably connected by the cooperation of the slot 103 and the protrusion. The locking method can enhance the sealing between the suction cup 3 and the base 1 and facilitate disassembly and replacement.

[0039] like Figure 1-3As shown: A pull tab 301 is provided on one side of the suction cup 3. The pull tab 301 and the suction cup 3 are integrally formed. The pull tab 301 and the suction cup 3 are not on the same horizontal plane and are slightly raised, which makes it easy to lift or remove the suction cup 3.

[0040] The working principle of this utility model is as follows:

[0041] An electronic control unit 4 is installed on the base 1, and an air pump motor 5, a main control board 6, an intake valve 7, a vent valve 8, and a battery assembly 9 are installed within the electronic control unit 4. The battery assembly 9 supplies power to the main control board 6. The main control board 6 is electrically connected to the air pump motor 5, the intake valve 7, and the vent valve 8, respectively. The intake valve 7 and the air pump motor 5 are connected via an air pipe, and the air inlet on the intake valve 7 is connected to the adsorption space through a through hole in the electronic control unit 4. During operation, the base 1 is placed on the ground, causing the suction cup 3 located below the base 1 to adhere to the ground. A sealed adsorption space is formed between the surface and the suction cup 3. Then, the air pump motor 5 is started. The air pump motor 5 draws the adsorption space into a vacuum chamber through the air intake valve 7, so that the suction cup 3 is firmly adsorbed to the ground. The main control board 6 has a preset automatic control program. When the air pressure in the vacuum chamber changes, it will trigger the air pump motor 5 to work again, so as to continue to draw air to reinforce the suction cup. When the operation is over, the main control board 6 only needs to control the pressure relief valve 8 to work, so that air can enter the vacuum chamber. At this time, the suction cup 3 will no longer be adsorbed to the ground, so that the auxiliary device can be put away.

[0042] The above structure uses an electrically controlled air extraction method to attach the suction cup 3 to the ground. The overall structure is simple and easy to operate. The suction cup has strong adhesion and is not prone to air leakage, which solves the technical problems of existing sit-up assist devices, such as cumbersome operation, easy air leakage, and poor suction.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
