Claims

1. A stroke head for a tubular motor, comprising a bottom shell, an end cover, and a circuit board, wherein the bottom shell and the end cover are assembled to form a cavity, and the circuit board is housed within the cavity, characterized in that, The travel head also includes a first antenna built into the cavity and electrically connected to the circuit board. A protective component is provided between the end cover and the circuit board. The protective component is configured to withstand pressure from the end cover when the end cover is assembled or under pressure to protect the first antenna.

2. The ram head of claim 1 wherein, The distance between the protective component and the inner surface of the end cap is less than or equal to the distance between the first antenna and the inner surface of the end cap.

3. The ram head of claim 1 wherein, The protective component is located in the peripheral area to the side of the first antenna.

4. The ram as defined in claim 2, wherein The first antenna protrudes from the circuit board toward the end cover, and the protective component has a pressure-bearing surface that is level with or higher than the apex of the protruding portion of the first antenna.

5. The ram as defined in claim 2, wherein The protective component is located close to or connected to the side of the first antenna to provide lateral support for the first antenna.

6. The ram as defined in claim 1, wherein The protective component is connected to the circuit board.

7. The ram as defined in claim 6, wherein The protective component is configured as a circuit board, the pins of the first antenna are electrically connected to the circuit board, and the circuit board is electrically connected to the circuit board.

8. The ram as defined in claim 1, wherein The protective component is connected to the inner wall of the bottom shell and extends towards the first antenna.

9. The ram as defined in claim 1, wherein The circuit board has a cutout that extends through its thickness, and the first antenna extends at least partially into the cutout.

10. The ram head of claim 9, wherein, The protective component extends at least partially into the hollowed-out portion.

11. The ram as defined in claim 9, wherein The cutout is constructed as a notch extending from the edge of the circuit board toward the center, and the bottom shell has a sidewall surrounding the circuit board, forming an unobstructed signal transmission and reception space between the first antenna and the sidewall.

12. The ram as defined in claim 1, wherein The first antenna is a spring antenna.

13. The ram as defined in claim 1, wherein The protective component is constructed in one of the following forms: columnar, rib-like, ribbed, or frame-like.

14. The ram as defined in claim 1, wherein It also includes a second antenna built into the cavity and electrically connected to the circuit board, wherein the first antenna is used to receive Sub-1GHz signals and the second antenna is used to receive intermediate frequency and / or high frequency signals.

15. The ram as defined in claim 14, wherein The first antenna and the second antenna protrude from the circuit board toward the end cover, and the protrusion height of the second antenna is less than that of the first antenna.

16. A tubular motor characterised in that, Includes the stroke head as described in any one of claims 1 to 15.
