Description

Technical Field

[0001] This invention relates to the field of electronic components, and in particular to a safety switch for providing safety protection on a treadmill. Background Technology

[0002] With the development of society, indoor treadmills have been continuously innovated in recent years as people pay more attention to health. Treadmills are one of the most common fitness equipment in gyms or homes. By rotating the running belt, they simulate the situation of a runner running on a normal road surface, achieving the effect of outdoor aerobic exercise indoors, and are very popular among consumers.

[0003] The current working principle of treadmills is as follows: when a person steps onto the running belt and turns it on, the running belt moves backward under the action of the drive motor. However, treadmills differ from running in a natural environment. If a person falls on a treadmill, the treadmill does not stop automatically, and the running belt continues to move rapidly backward under the action of the drive motor. This poses a significant risk of further injury if the person falls, resulting in low safety. Subsequently, electric treadmills are equipped with safety switches, also called emergency switches. These are safety devices that can forcibly cut off the power in case of an emergency. Most of these safety switches are located on the control panel of the treadmill. Currently, some safety switches are magnetic switches, connecting the user to a magnetic buckle via a safety cord. When the user falls, they pull off the buckle, thus forcibly cutting off the power. However, in the use of magnetic emergency switches, the sensing metal plate may reset due to inertia, preventing the emergency stop from being achieved. Some safety switches are push-button switches, where the user presses the button to forcibly cut off the power. This type of switch heavily relies on the user's reaction time; if the reaction is not timely, it will not provide safety. Summary of the Invention

[0004] The purpose of this invention is to provide a safety switch for treadmills that not only ensures safety but also has a simple structure and is easy to manufacture and use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The treadmill safety switch has the following features: The outer casing is composed of two insulating bases placed on the left and right, each insulating base having a receiving groove and a socket communicating with the receiving groove; Two terminals are respectively placed into the receiving slots of two insulating bases; the terminals have a contact portion and a wiring portion, the wiring portion extends from the insulating base for connecting the corresponding wire; the contact portion is located in the receiving slot and is supported by an elastic element, so that the contact portion protrudes into the socket; when the external plug is inserted into the socket, the contact portion is in close contact with the external plug under the support of the elastic element and conducts electricity. A separator plate is embedded between two insulating bases and is used to isolate the two terminals.

[0006] The above solution is further described in that the receiving groove is designed to be recessed from the combined end face of the insulating base. The receiving groove is L-shaped, and the socket is formed by the horizontal fold of the receiving groove penetrating through the front of the insulating base. The terminal is also L-shaped, and the contact part is a horizontally folded flat plate.

[0007] The above solution further includes a positioning groove on the insulating base, which is located on one side of the contact portion and communicates with the receiving groove; the elastic element is a compression spring placed in the positioning groove, one end of the elastic element supports the bottom of the positioning groove, and the other end of the elastic element supports the contact portion of the top.

[0008] The above solution is further provided that the positioning groove has a positioning port leading to the combined part of the two insulating seats, and the positioning port allows the pre-set inserts on the partition plate to be inserted into the positioning groove.

[0009] A further improvement of the above scheme is that the partition plate has a tongue portion that extends from the insulating base together with the wiring portion, and the length of the tongue portion extending out is greater than the length of the wiring portion extending out.

[0010] A further improvement in the above scheme is that the two insulating seats are locked together by screws, and the two insulating seats together clamp the partition plate.

[0011] A further improvement in the above solution is that the inner bottom of the receiving tank has heat dissipation holes that connect to the outside.

[0012] Furthermore, the aforementioned solution includes a mounting portion that protrudes outward from the insulating base.

[0013] The above solution is further described in that the tongue portion is arranged in a side-standing form between the wiring portions of the two terminals, and the height of the tongue portion in the side-standing direction is greater than the thickness of the wiring portion in the same direction, so that the orthogonal projection of the wiring portion falls completely on the tongue portion.

[0014] Furthermore, the above solution includes an avoidance groove on the insulating base, with the avoidance groove and the positioning groove located on opposite sides of the contact portion, providing clearance space for the insertion of external plugs.

[0015] This invention utilizes a unique structural design, connecting to the control circuit via two terminals with a socket. When an external plug is inserted, the contact portion of the terminal, supported by an elastic element, makes tight contact with the plug, ensuring normal operation of the control circuit. Conversely, when the external plug is removed, the control circuit disconnects or outputs a signal to forcibly cut off the power, ensuring safety. In use, this invention is located on the treadmill's control panel, while the external plug is connected to the user via a safety cord. If the user falls, they can easily pull off the external plug, forcibly cutting off the power and stopping the treadmill, reducing the need for manual operation and better protecting the user. This invention provides a hot-swappable safety switch, enabling rapid power cut-off while preventing situations where emergency stops cannot be achieved, thus enhancing the safety of the treadmill.

[0016] The invention has a simple structure. The outer shell is composed of two insulating seats placed on the left and right. The receiving groove of the insulating seat facilitates the assembly of terminals, and a partition plate is introduced to isolate the two terminals, which simplifies the manufacturing structure, makes it compact, easy to manufacture and implement, and achieves better practicality.

Detailed Implementation

[0018] The following will further explain the concept, specific structure, and technical effects of the present invention in conjunction with the accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention.

[0019] It should be noted that in the description of this invention, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., which indicate the direction or positional relationship, are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and is not intended to indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0020] See Figure 1 , 2As shown in Figures 3, 4, and 5, this invention relates to a safety switch for a treadmill, which is suitable for installation on the control panel of the treadmill head and works in conjunction with an external plug. The external plug is connected to the user via a safety rope. When the user falls, they can pull off the external plug, thereby forcibly cutting off the power supply, stopping the treadmill, and protecting the user.

[0021] This invention includes a housing 1, two terminals 2, and a partition plate 4. The housing 1 is composed of two insulating seats 11 positioned left and right. The insulating seats 11 are injection molded, and each insulating seat 11 has a receiving groove 111 and a socket 112 communicating with the receiving groove 111. The socket 112 allows for the insertion and removal of external plugs. The two terminals 2 are respectively placed into the receiving grooves 111 of the two insulating seats 11. Each terminal has a contact portion 21 and a wiring portion 22. The wiring portion 22 extends from the insulating seat 11 and is used to connect corresponding wires to the control circuit on the treadmill. The contact portion 21 is located in the receiving groove 111 and is supported by an elastic member 3, so that the contact portion 21 protrudes into the socket 112. When an external plug is inserted into the socket 112, the contact portion 21, supported by the elastic member 3, makes tight contact with the external plug and conducts electricity, allowing the control circuit to work normally. The partition plate 4 is embedded between the two insulating seats 11 and is used to isolate the two terminals 2 to prevent short circuits. Furthermore, the two insulating seats 11 are locked together by screws, and the two insulating seats 11 together clamp the partition plate 4, which not only makes the connection stable, but also simplifies the assembly structure.

[0022] The receiving groove 111 is recessed from the combined end face of the insulating base 11, extending to the combined end face of the insulating base 11. This facilitates terminal insertion and assembly, simplifying the assembly process. The receiving groove 111 is L-shaped, and the insertion port 112 is formed by the horizontal bend of the receiving groove 111 penetrating the front of the insulating base 11. The terminal 2 is also L-shaped, with the contact portion 21 being a horizontally folded flat plate to increase the contact area. The corresponding insertion port 112 is flat, facilitating contact and conduction between the contact portion 21 and external plugs, thus improving contact stability. The inner bottom of the receiving groove 111 has heat dissipation holes 1111 that connect to the outside, increasing airflow, dissipating heat from the contact portion 21, and extending its service life.

[0023] The insulating base 11 is also provided with a positioning groove 113, which is located on one side of the contact portion 21 and communicates with the receiving groove 111. The elastic element 3 is a compression spring and is placed in the positioning groove 113. One end of the elastic element 3 supports the bottom of the positioning groove 113, and the other end of the elastic element 3 supports the contact portion 21 of the terminal, so that the contact portion 21 protrudes into the socket 112. The elastic element 3 supports the terminal, allowing it to float relatively elastically in the receiving groove 111. When an external plug is inserted into the socket 112, the contact portion 21 can relatively avoid it, which is conducive to the insertion of the external plug. Under the support of the elastic element 3, the contact portion 21 also springs towards the external plug, forming a tight contact and conducting. The positioning groove 113 also has a positioning port leading to the combined portion of the two insulating seats 11. The positioning port allows the pre-set insert 41 on the partition plate 4 to be inserted into the positioning groove 113, increasing the assembly structure and positioning of the partition plate 4, ensuring that the partition plate 4 effectively isolates the two terminals 2. The insertion of the insert 41 into the positioning groove 113 further controls the elastic element 3 in the positioning groove 113, ensuring the normal elastic expansion and contraction of the elastic element 3. The positioning port of the positioning groove 113 extends to the combined end face of the insulating seat 11, which also facilitates the assembly of the elastic element 3 from the positioning port into the positioning groove 113. The partition plate 4 is embedded between the two insulating seats 11, which also covers the receiving groove 111 and the positioning groove 113, providing isolation while further restricting and protecting the terminals.

[0024] In this embodiment, the insulating base 11 is also provided with a clearance groove 114. The clearance groove 114 and the positioning groove 113 are respectively located on both sides of the contact portion 21. The clearance groove 114 leaves the corresponding side of the contact portion 21 empty, providing clearance space for the insertion of external plug-in, so that the external plug-in 100 can better push the contact portion 21 when it is inserted. The clearance groove 114 can also guide, limit and position the external plug-in 100, ensuring that the external plug-in 100 and the contact portion 21 are in close contact. In this embodiment, the end of the contact portion 21 is bent to form a guide hook, so that the arc surface first contacts the external plug-in 100, which has a guiding function, increases the insertion and removal experience and service life.

[0025] In this embodiment, the partition plate 4 has a tongue portion 42 that extends from the insulating base 11 along with the wiring portion 22. The length of the tongue portion 42 extending out is greater than the length of the wiring portion 22 extending out. The tongue portion 42 is arranged in a side-standing form between the wiring portions 22 of the two terminals 2. The height of the tongue portion 42 in the side-standing direction is greater than the thickness of the wiring portion 22 in the same direction, so that the orthographic projection of the wiring portion 22 falls completely on the tongue portion 42. With this design, the area of ​​the tongue portion 42 is large, completely blocking the wiring portion 22, increasing the isolation effect and improving the safety of use.

[0026] In this embodiment, the outer casing 1 also has a mounting portion 12 protruding outward from the insulating base 11. The mounting portion 12 is in the form of a hook and can be screwed onto the treadmill. In this embodiment, each insulating base has at least two mounting portions 12 that protrude in opposite directions from the opposite side of the insulating base, so that the outer casing 1 can be connected to the treadmill at multiple points and in multiple directions, increasing installation stability and making installation convenient and secure.

[0027] Figure 5 As shown, the present invention is installed on the control panel of the treadmill head and connected to the wires. The socket 112 protrudes from the control panel to facilitate the insertion of the external plug 100. The external plug 100 is connected to the user via a safety rope 200. When the user falls while using the treadmill, the safety rope 200 pulls the external plug 100 out, causing it to exit from the socket 112 and disconnect from the contact part 21. At this time, the control circuit is disconnected or a corresponding signal is output to forcibly cut off the power, thereby stopping the treadmill and protecting the user.

[0028] The treadmill safety switch provided by this invention has a housing composed of two insulating bases placed on the left and right. The receiving grooves of the insulating bases facilitate terminal assembly, and a separator plate isolates the two terminals, simplifying the manufacturing structure. Its compact size makes it easy to manufacture and implement. The switch connects to the control circuit via two terminals, with a socket provided. When an external plug is inserted into the socket, the contact portion of the terminal, supported by an elastic element, makes tight contact with the external plug, ensuring normal operation of the control circuit. Conversely, when the external plug is removed, the control circuit disconnects or outputs a signal to forcibly cut off the power, ensuring safety. In use, this invention is located on the treadmill's control panel, while the external plug is connected to the user via a safety cord. If the user falls, they can pull off the external plug, forcibly cutting off the power and stopping the treadmill, protecting the user. The simple structure and excellent practicality make it suitable for widespread use.

[0029] While preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention should not be limited to structures and operations that are exactly the same as those described above and shown in the drawings. Those skilled in the art can make many equivalent improvements and variations to the above embodiments through logical analysis, reasoning, or limited experiments without departing from the concept and scope of the present invention, but all such improvements and variations should fall within the scope of protection claimed by the present invention.
