Description

Technical Field

[0001] The utility model belongs to the technical field of automotive equipment, and more particularly, to a sliding door limit switch. Background Art

[0002] In the existing automotive side sliding door limit switch, it usually consists of 4 contacts, namely 2 contacts for judging the unlocking and closing of the door lock and 2 contacts for judging the opening and closing of the door. The two contacts for judging the opening and closing of the door need to constantly judge whether the contacts are in contact during static and vehicle driving. Since the sliding door does not move completely in a straight line during the opening and closing process, but has an arc at the front end of the straight line, it is easy to cause the misalignment of the 2 contacts for judging the opening and closing of the door. Also, when the vehicle is accelerating rapidly, turning, or passing through bumpy roads during driving, the contacts are also prone to misalignment, resulting in false alarms on the instrument that the sliding door is not closed. When the movement gap of the sliding door exceeds the effective stroke of the sliding door switch during closing, it will also provide incorrect information to the driver, posing a driving safety problem.

[0022] As Figure 1 , Figure 2 and Figure 5 shown, a sliding door limit switch includes a column limit switch assembly and a sliding door limit switch assembly. The column limit switch assembly is fixedly installed on the middle door column of the vehicle, and the sliding door limit switch assembly is fixedly installed on the sliding door of the vehicle. The column limit switch assembly and the sliding door limit switch assembly cooperate with each other. The column limit switch assembly includes the column limit switch body 2, and the first rubber sleeve 1 is fixedly sleeved on the column limit switch body 2. By providing the first rubber sleeve 1 and the second rubber sleeve 6, the column limit switch body 2 and the sliding door limit switch body 7 can be protected against water and shock.

[0023] Both ends of the vertical column limit switch body 2 are fixedly provided with mounting holes 201. The mounting holes 201 are matched with bolts to fixedly connect the vertical column limit switch body 2 to the middle door column of the vehicle. In the middle of the vertical column limit switch body 2, a limit bump 202 and a mounting groove 203 are fixedly arranged. A limit slot 202A is fixedly opened on the limit bump 202. A static contact piece 3 is fixedly installed on the limit bump 202. A door state switch 4 is fixedly installed in the mounting groove 203. Wires harness assembly 5 is connected to the rear parts of both the static contact piece 3 and the door state switch 4. The sliding door limit switch assembly includes a sliding door limit switch body 7. A rubber sleeve 6 is sleeved around the sliding door limit switch body 7. Both ends of the sliding door limit switch body 7 are fixedly provided with mounting holes 701. The mounting holes 701 are matched with bolts to fixedly connect the sliding door limit switch body 7 to the side sliding door of the vehicle. In the middle of the sliding door limit switch body 7, a limit groove 702 and a contact boss 703 are fixedly arranged. The limit groove 702 is matched with the limit bump 202. By setting the limit groove 702 and the limit bump 202, after the door is closed, no matter how bumpy and shaky, the static contact piece 3 and the moving contact 801 can always keep in contact, avoiding misreporting of the door lock state due to contact misalignment and affecting driving safety. A circular sliding groove 702A is fixedly opened on the limit groove 702. A car lock state switch 8 is fixedly installed inside the circular sliding groove 702A. Wires harness assembly 9 is connected to the rear part of the car lock state switch 8.

[0024] As Figure 3 shown, both sides of the rubber sleeve 1 are fixedly provided with openings 101. The openings 101 are matched with the mounting holes 201. In the middle of the rubber sleeve 1, an opening 102 and an elastic cap 103 are fixedly arranged. The opening 102 is matched with the limit bump 202. The elastic cap 103 is matched with the door state switch 4. By covering the door state switch 4 with the elastic cap 103, the door state switch 4 can be protected from damage and its service life can be increased.

[0025] As Figure 4As shown in the figure, the door state switch 4 includes a U-shaped contact piece 404 and an insertion piece 405. Both the U-shaped contact piece 404 and the insertion piece 405 are fixedly connected to the side wall of the installation groove 203. A first spring 403 is fixedly connected to the bottom of the installation groove 203. The other end of the first spring 403 is fixedly connected to a switch reed 402. A switch plunger 401 is fixedly connected to the front part of the switch reed 402. The switch plunger 401 is matched with the contact boss 703. Both the U-shaped contact piece 404 and the insertion piece 405 are matched with the switch reed 402. The rear parts of both the U-shaped contact piece 404 and the insertion piece 405 are fixedly connected to the first wire harness assembly 5. When the vehicle's sliding door is closed, the switch plunger 401 contacts the contact boss 703 and gradually compresses the first spring 403. The switch plunger 401 slides inside the installation groove 203 and pushes the switch reed 402 backward, causing the switch reed 402 to contact the U-shaped contact piece 404 and the insertion piece 405, connecting the circuit. At this time, the vehicle instrument shows that the car door is closed. Similarly, when the sliding door is opened, the switch reed 402 separates from the U-shaped contact piece 404 and the insertion piece 405 under the push of the first spring 403, disconnecting the circuit. At this time, the vehicle instrument shows that the car door is open.

[0026] A limit card 301 is fixedly arranged on the static contact piece 3. The limit card 301 is matched with the limit slot 202A. The rear part of the static contact piece 3 is fixedly connected to the first wire harness assembly 5. Insert the limit card 301 into the limit slot 202A to realize the installation and fixation of the static contact piece 3 on the limit bump 202.

[0027] As Figure 6 As shown in the figure, the car lock state switch 8 includes a moving contact 801, a second spring 802, and a retaining ring 803. The retaining ring 803 is fixedly connected to the circular chute 702A. The retaining ring 803 is also fixedly connected to the rear part of the second spring 802. The front part of the second spring 802 is fixedly connected to the moving contact 801. The moving contact 801 is matched with the static contact piece 3. The rear part of the moving contact 801 is fixedly connected to the second wire harness assembly 9. When the door lock is closed, the moving contact 801 contacts the static contact piece 3 to form a circuit. Just press the unlocking button to drive the motor to unlock. By using the moving contact 801 and the static contact piece 3 to replace the traditional contact, the contact area is greatly increased, avoiding the occurrence of misreporting the door lock due to the small contact area of the contacts and easy dislocation.

[0028] With the present utility model, by providing the limit groove 702 and the limit bump 202, after the vehicle door is closed, regardless of bumps and vibrations, the static contact piece 3 and the moving contact 801 can always maintain contact, avoiding false alarms of the door lock state due to misalignment of the contacts, which may affect driving safety. By providing the first rubber sleeve 1 and the second rubber sleeve 6, waterproof and shock-absorbing protection can be provided for the pillar limit switch body 2 and the sliding door limit switch body 7. By using the moving contact 801 and the static contact piece 3 to replace the traditional contact, the contact area is greatly increased, avoiding misalignment of the door lock due to the small contact area of the contacts, which may lead to false alarms.
