Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to an ab wheel. Background Technology

[0002] An ab wheel with a counting function is a type of exercise equipment that combines fitness and technology. It uses built-in sensors (such as Hall effect sensors) to accurately detect the number of rotations of the roller and transmits the data to a display screen or mobile app in real time, helping users to intuitively understand their exercise volume and improve their training effect and motivation.

[0003] However, the Hall element needs to be connected to the main control board via wires. In a small and compact device like an ab wheel, the wiring space is limited, making wire routing inconvenient during assembly and affecting the assembly efficiency of the ab wheel.

[0004] The above background information is provided only to aid in understanding the inventive concept and technical solution of this invention. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application.

[0043] Example 1

[0044] Please refer to Figures 1 to 3Embodiment 1 of this utility model is as follows: an ab wheel, comprising a main body 1, a main control board 2, a bracket 3, a wire 4, and a decorative cover 5. The main body 1 includes a bottom shell 11 and a top shell. The bottom shell 11 and the top shell are connected to form an accommodating space. The top shell is located above the bottom shell 11. Both ends of the top shell have contact areas for contacting the user's elbows. The bottom shell 11 is provided with an installation port 12, which communicates with the accommodating space. The main control board 2 is disposed inside the main body 1, specifically, the main control board 2 is installed within the accommodating space. The bracket 3 is connected to two rollers 6. The top of the bracket 3 passes through the installation port 12 into the main body 1. The bracket 3 has an upper wire groove 31 on its inner upper part and a lower wire groove 32 and a circuit board 33 on its outer lower part. The circuit board 33 has a Hall element for detecting the number of rotations of the roller 6. The bracket 3 also has a wire through-hole 34 connecting the upper wire groove 31 and the lower wire groove 32. In this embodiment, the wire 4 is a flat transmission cable. One end of the wire 4 is sequentially inserted into the mounting port 12, the upper wire groove 31, the wire through-hole 34 and the lower wire groove 32 and connected to the circuit board 33 to conduct the Hall element. The other end of the wire 4 is connected to the main control board 2. The decorative cover 5 is installed on the lower part of the outer side of the bracket 3 to cover the wire 4 and the circuit board 33.

[0045] To facilitate the arrangement of the wire 4, the other end of the wire 4 is provided with a first mating connector, and the main control board 2 is provided with a second mating connector for mating with the first mating connector. At this time, the wire 4 and the main control board 2 are connected through the cooperation of the first mating connector and the second mating connector.

[0046] The mounting port 12 has a surrounding wall 13 along its edge, and a wire passage groove 14 is provided on the surrounding wall 13. The other end of the wire 4 passes through the mounting port 12 via the wire passage groove 14. Preferably, the wire passage groove 14 connects to the top of the surrounding wall 13. The surrounding wall 13 can guide the top of the bracket 3 into the receiving space, while the presence of the wire passage groove 14 can prevent the surrounding wall 13 from adversely affecting the routing of the wire 4. While ensuring convenient routing of the wire 4, it is beneficial to shorten the overall length of the wire 4 and reduce the raw material cost of the wire 4.

[0047] The area of ​​the wire 4 within the accommodating space has a bent section 41, which is formed by bending a portion of the wire 4. Preferably, the bent section 41 is S-shaped. After the other end of the wire 4 is connected to the main control board 2, the assembler can use the bent section 41 to pull and tighten the area of ​​the wire 4 in the upper wire groove 31 to prevent the wire 4 in the upper wire groove 31 from being too long and interfering with the roller 6, thus ensuring the working stability of the ab wheel.

[0048] In this embodiment, the ab wheel also includes a support rod 7 located within the receiving space. There are two supports 3 arranged opposite each other. The bottom shell 11 has two mounting openings 12, each corresponding to one of the supports 3. The support rod 7 connects the two supports 3, and the top of each support 3 abuts against the face shell. Preferably, the support rod 7 contacts the face shell. This prevents the supports 3 from accidentally detaching from the main body 1 and also distributes the force on the face shell, reducing the risk of localized damage.

[0049] The main body 1 is provided with a power supply 8 that is connected to the main control board 2. Specifically, the main body 1 is provided with a battery compartment, and the battery compartment is provided with a conductive terminal that is electrically connected to the main control board 2. A dry cell battery serving as the power supply 8 is installed in the battery compartment, and the dry cell battery is in contact with the conductive terminal for connection.

[0050] The main body 1 is connected to a shelf 9, which is used to place items such as mobile phones and watches.

[0051] The main body 1 is connected to two grip handles 10, which are located on the same side of the main body 1 as the shelf 9, so that users can easily view mobile phones and other items placed on the shelf 9.

[0052] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings under the utility model concept, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
