[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figures 1 to 9 As shown, the compact floor door switch device of the utility model comprises a switch panel 1 and a switch assembly 2. The switch assembly 2 is provided with a plurality of mounting holes 3, and the pressing member 4 is arranged in the mounting holes 3.

[0024] The switch assembly 2 is provided with a pressing member 4, a reset member 5 and a shell 6. The pressing member 4 is arranged in the mounting hole 3. The shell 6 is provided with a fixing ear 7. The shell 6 is arranged on the switch panel 1. The shell 6 is fixed to the switch panel 1 by bolts to fix the fixing ear 7, thereby fixing the switch assembly 2.

[0025] The interior of the shell 6 is hollowed out to form an installation chamber 8, and the reset member 5 is arranged in the installation chamber 8. Symmetrical positioning blocks 9 are provided on the pressing member 4, and a positioning area 10 is formed between the positioning blocks 9. A connecting terminal 11 is provided in the positioning area 10, and the connecting terminal 11 is installed on the pressing member 4 by screws.

[0026] A limiting ring 12 is provided inside the housing 6, and a protrusion 13 and a recessed groove 14 are provided on the limiting ring 12, and a positioning protrusion 15 that cooperates with the recessed groove 14 is provided on the reset member 5. The protrusion 13 and the recessed groove 14 are used to limit the reset member 5, so that the reset member 5 will not go over the limiting ring 12 after being deformed by force. And after the reset member 5 is deformed by force, it will still be restricted by the limiting ring 12, so that after the external force is lost, it can be reset under the elastic force of the reset member 5 itself, so that the power terminal 16 and the connection terminal 11 are separated, which is convenient for the next pressing.

[0027] The reset member 5 is provided with a through hole 17 for the connection terminal 11 to pass through, and a symmetrical power terminal 16 is provided in the installation chamber 8. The connection terminal 11 passes through the through hole 17 to maintain contact with the power terminal 16. The connection terminal 11 is composed of a mounting section 18 and a contact section 19. The mounting section 18 is fixed in the positioning area 10 by screws, and the contact section 19 is used to drive the contact section 19 on the connection terminal 11 to pass through the through hole 17 after the pressing member 4 pushes the reset member 5, so as to maintain the contact section 19 in contact with the power terminal 16 to achieve electrical connection.

[0028] The reset member 5 can not only realize the elastic reset of the pressing member 4, but also realize sealing through the cooperation of the protrusion 13, the recessed groove 14 and the positioning protrusion 15, so as to prevent foreign impurities such as dust and water vapor from entering the installation chamber 8, thereby affecting the electrical contact between the power terminal 16 and the connecting terminal 11, thereby extending the service life of the floor door switch assembly 2 and protecting the switch assembly 2.

[0029] A raised portion 20 is provided in the middle of the reset member 5 and is raised toward the electrical terminal 16. A protrusion 21 is formed in the middle of the raised portion 20 and is raised toward the connection terminal 11. The through hole 17 is provided on the raised portion 20, and the protrusion 21 is in contact with the positioning block 9. An arc segment 22 is also provided on the reset member 5, and the arc segment 22 connects the raised portion 20 and the positioning protrusion 15.

[0030] The power terminal 16 is composed of a mounting portion 23 and a symmetrically arranged inclined portion 24, an arc portion 25 and a guide portion 26. A clamping area 27 is formed between the arc portions 25. The width of the clamping area 27 is smaller than the width of the contact segment 19, so that the arc portion 25 can clamp the contact segment 19. The mounting portion 23 is provided with symmetrical legs 28, the housing 6 is provided with fixing holes 33 that match the legs 28, and the legs 28 are provided with a power connection hole 29. The leg 28 is bent at the portion that passes through the fixing hole 33 to keep the power terminal 16 fixed.

[0031] The pressing member 4 is composed of a pressing portion 30, a blocking portion 31 and a pushing portion 32. The diameter of the pressing portion 30 matches the diameter of the mounting hole 3, the diameter of the blocking portion 31 is larger than the diameter of the pressing portion 30, and the positioning block 9 is arranged on the pushing portion 32. During installation, the reset member 5 is first installed in the installation chamber 8, and then the pressing member 4 is installed, and finally the housing 6 together with the reset member 5 and the pressing member 4 are installed on the switch panel 1.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
