Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of intelligent massage, and in particular relates to an anti-impact limiting device for a dual-core massage appliance. Background Art
[0002] Currently, dual-movement massage devices are designed with two movements responsible for different massage functions, and they operate independently through a control system. However, due to unreasonable design layouts of the dual movements, overlapping preset running trajectories, or other improper use, the two movements may collide with each other when running in opposite directions. Although existing improvement plans, in order to solve this problem, use external Hall or mechanical switches and structures to provide impact stop signals to each movement when the movements are close together, there is a situation where one of the two movements will have an impact signal while the other will not have an impact limit signal, which will still cause the two movements to mechanically collide, resulting in abnormal noise and structural damage.
[0003] Therefore, there is a need for an anti-impact limit device for a dual-movement massage appliance that can improve the reliability of the impact limit, extend the life of the impact limit switch, and avoid mechanical damage to the movement and guide rails. Utility Model Content
[0004] The purpose of the utility model is to solve the defects of existing dual-movement massage appliances in that the impact limit signals are not synchronized during the anti-impact limit operation, which leads to unreliable impact limit devices and easy failure of impact limit switches. The utility model provides an anti-impact limit device for dual-movement massage appliances that can improve the reliability of impact limit, extend the service life of impact limit switches, and avoid mechanical damage to the movement and guide rails.
[0005] The utility model describes an anti-impact limit device for a dual-movement massager, comprising a first anti-impact limit component, a second anti-impact limit component and a main control board; the first anti-impact limit component is arranged on the first movement and close to the side of the second movement, and the second anti-impact limit component is arranged on the second movement and close to the side of the first movement. When the first movement and the second movement move toward each other, the first anti-impact limit component and the second anti-impact limit component approach each other until they contact, the output ends of the first anti-impact limit component and the second anti-impact limit component are connected to the input end of the main control board, and the control ends of the first movement and the second movement are both connected to the output end of the main control board.
[0006] Furthermore: a driving board and a control switch are provided in both the first movement and the second movement, the output end of the main control board is connected to the input end of the driving board, and the output end of the driving board is connected to the input end of the control switch.
[0007] Furthermore: the control switch is a mechanical switch.
[0008] Furthermore: the first movement and the second movement are both arranged on the SL guide rail.
[0009] Furthermore: the first anti-impact limit assembly includes a collision limit structure assembly and a fixing assembly, the collision limit structure assembly includes an anti-collision switch, a switch pressure plate, a pin shaft, a switch fixing plate and a spring, the switch pressure plate is connected to the switch fixing plate through a pin shaft, the switch pressure plate generates pressure on the anti-collision switch through a lever action to cause the anti-collision switch to generate a signal, and the switch pressure plate is reset through the spring.
[0010] The beneficial effects of the utility model are:
[0011] The present invention provides a dual movement on two SL guide rails with an anti-shock limit assembly. When the two movements collide, regardless of which movement caused the collision, both movements can be stopped from moving up and down at the same time, thus avoiding mechanical damage to the movement and the SL guide rails. This avoids to the greatest extent possible the situation where the movement is damaged due to unreasonable design or overlapping of preset running trajectories in different massage modes. At the same time, it also avoids mechanical damage to the SL guide rails due to hard contact of the movement. In addition, this mechanical anti-shock limit assembly can not only avoid the situation where only one movement stops when an impact signal is generated, but the other movement does not stop.

[0017] Example 1
[0018] Combine Figure 1-Figure 3 To describe this embodiment, this embodiment discloses an anti-impact limit device for a dual-movement massage appliance, comprising a first anti-impact limit component, a second anti-impact limit component and a main control board 5; the first anti-impact limit component is arranged on the first movement 1 and close to the side of the second movement 2, and the second anti-impact limit component is arranged on the second movement 2 and close to the side of the first movement 1. When the first movement 1 and the second movement 2 move toward each other, the first anti-impact limit component and the second anti-impact limit component approach each other until they contact, and the output ends of the first anti-impact limit component and the second anti-impact limit component are connected to the input end of the main control board 5, and the control ends of the first movement 1 and the second movement 2 are both connected to the output end of the main control board 5. A control switch, i.e. a mechanical switch, is adopted on each of the two movements. When they move towards each other, they are assisted by a lever-type mechanical structure in an anti-impact limit assembly. The anti-impact limit function is achieved through the squeezing switch of the lever-type mechanical structure. Because both movements are arranged on the SL guide rail 4, when the two movements collide with each other, the lever structure of the squeezing switch may be misaligned, resulting in the stop signals of the two movements not appearing at the same time. In this embodiment, the effective signal of the impact limit of one of the movements is transmitted to the main control board 5, and the main control board 5 then transfers it to the other movement. The other movement regards this signal as its anti-impact limit signal and stops its moving action, thereby greatly improving the reliability of the impact limit and the life of the impact limit switch.
[0019] Both the first and second movements 1 and 2 are equipped with a driver board and a control switch. The output of the main control board 5 is connected to the input of the driver board, which in turn is connected to the input of the control switch. The driver can effectively identify impact signals sent by the main control board and shut off the power to the current movement through the control switch, preventing the continued force of a hard collision.
[0020] The control switch uses a mechanical switch 3. Mechanical switches have a relatively simple structure and lack complex electronic components. They typically have a long service life and can withstand prolonged switching operations without damage. Compared to electronic switches, mechanical switches are less susceptible to external electromagnetic interference and can maintain stable performance. The manufacturing process is relatively simple and the manufacturing cost is low. In the event of a fault, repair is relatively easy and the repair cost is low. Furthermore, accidents are less likely to occur. Mechanical switches can also adapt to a variety of operating environments, including harsh environments such as high temperatures, low temperatures, and humidity. They also have dustproof and waterproof features, allowing them to operate normally in even harsher environments.
[0021] The first movement 1 and the second movement 2 are both arranged on the SL guide rail 4. In existing massage appliances, the SL guide rail is generally used. As a high-end guide rail type in massage chairs, it combines the advantages of the S-shaped guide rail and the L-shaped guide rail, and can provide a massage path that better fits the curve of the human body and covers a wider massage area.
[0022] The first anti-impact limit assembly includes a collision limit structure assembly and a fixing assembly. The collision limit structure assembly includes an anti-collision switch 31, a switch pressure plate 32, a pin shaft 33, a switch fixing plate 34 and a spring 35. The switch pressure plate 32 is connected to the switch fixing plate 34 through the pin shaft 33. The switch pressure plate 34 generates pressure on the anti-collision switch 31 through a lever action to cause the anti-collision switch 31 to generate a signal, and the switch pressure plate 32 is reset through the spring 35.
[0023] Example 2
[0024] This embodiment is described in conjunction with Example 1. This embodiment discloses an anti-impact limiting method for an anti-impact limiting device of a dual-movement massage appliance, which specifically includes the following steps:
[0025] S1: Start the first movement 1 and / or the second movement 2 until the first anti-shock limit assembly and the second anti-shock limit assembly contact each other;
[0026] S2: The first anti-impact limiter assembly and the second anti-impact limiter assembly both send a collision signal to the main control board 5;
[0027] S3: The main control board 5 sends a stop signal to the first movement 1 and the second movement 2 respectively.
[0028] In S3 , the main control board 5 sends stop instructions to the drive boards of the first movement 1 and the second movement 2 respectively. The drive boards drive the control switches to stop the movement of the first movement 1 and the second movement 2 by cutting off the power.
[0029] If the driving board of the first movement 1 or the second movement 2 detects that the current movement is not moving when receiving the stop command, it will not respond to the received stop command.
