Embodiment 1

[0073] see Figure 9 to Figure 15 , a new sliding rail locking mechanism shown in the figure includes a locking tooth plate 30 for locking the upper rail 10 and the lower rail 20 in the seat sliding rail.

[0074] The locking tooth plate 30 is made up of a locking strength plate 31 and an anti-backlash plate 32. Eight locking strength teeth 31a are symmetrically distributed on the locking strength plate 31, and four anti-backlash teeth 32a are arranged on the anti-backlash plate 32 respectively. The plate 32 is fixed on the bottom surface of the locking strength plate 31 by riveting, wherein the four anti-backlash teeth 32a are combined with the corresponding four locking strength teeth 31a to form four locking teeth in the present invention.

[0075] The area where the lock tooth window 11 in the upper rail 10 cooperates with the anti-backlash tooth 32a is the lock area 11a, and the lock angle of the lock area 11a is 10°. The lock tooth window 11 in the upper rail 10 and the ...

Embodiment 2

[0084] see Figure 16 to Figure 17 , the locking angle of the locking area 11a of the upper locking tooth window 11 in the upper rail 10 is 10°, the self-locking angle of the locking area 11b of the upper locking tooth window 11 in the upper rail 10 is -10°, and the lower rail The locking angle of the locking area 21a of the lower locking tooth window 21 in 20 is 10°, and the self-locking angle of the locking area 21b of the lower locking tooth window 21 in the lower rail 20 is -10°. All the other are with embodiment 1.

Embodiment 3

[0086] see Figure 18 to Figure 25 , a new sliding rail locking mechanism shown in the figure includes a locking tooth plate 30 for locking the upper rail 10 and the lower rail 20 in the seat sliding rail.

[0087] The locking tooth plate 30 is made up of a locking strength plate 31 and an anti-backlash plate 32. Eight locking strength teeth 31a are symmetrically distributed on the locking strength plate 31, and four anti-backlash teeth 32a are arranged on the anti-backlash plate 32 respectively. The plate 32 is fixed on the top surface of the locking strength plate 31 by riveting, wherein the four anti-backlash teeth 32a are combined with the corresponding four locking strength teeth 31a to form four locking teeth in the present invention.

[0088] The area where the lock tooth window 11 in the upper rail 10 cooperates with the anti-backlash tooth 32a is the lock area 11a, and the lock angle of the lock area 11a is 10°. The lock tooth window 11 in the upper rail 10 and the lo...

Abstract

The invention discloses a novel sliding rail locking mechanism and sliding rail. The novel sliding rail locking mechanism comprises locking tooth plates; each locking tooth plate is provided with a plurality of locking teeth; each locking tooth is in locking fit with an upper locking tooth window in an upper rail or / and a lower locking tooth window in a lower rail, and at least one of locking teeth is formed by superposing and fixing at least one locking strength tooth and a clearance eliminating tooth together; under a normal locking state, the clearance eliminating teeth are in locking fit with the upper locking tooth windows in the upper rail or / and the lower locking tooth windows in the lower rail and eliminate locking fit clearances; the locking strength teeth are not in locking fit with the upper locking tooth windows in the upper rail or / and the lower locking tooth windows in the lower rail; and only during collision, the locking strength teeth are in locking fit with the upperlocking tooth windows in the upper rail or / and the lower locking tooth windows in the lower rail. The novel sliding rail locking mechanism absolutely guarantees that the slippage phenomenon is absentin the collision course; locking strength tooth plates are employed to meet the requirement of locking safety; clearance eliminating tooth plates are employed to meet the requirement of unlocking comfort; and the locking strength tooth plates and the clearance eliminating tooth plates are separated manufactured, so that the manufacturing difficulty is lowered.

Description

technical field [0001] The invention relates to the technical field of seat slide rails, in particular to a novel slide rail locking mechanism and slide rails. Background technique [0002] As the core part of the seat design, the slide rail must provide sufficient locking strength during a collision. The locking function is one of the most important safety indicators of the slide rail. It needs to be 100% guaranteed under any working conditions. In the vehicle Keep the position of the seat unchanged during a low-speed collision to avoid secondary injuries and protect the driver and passengers. GM CTS seatingMechanisms-2.2.5 requires that the monorail forward / rear locking strength must meet a minimum of 20kN. Nissan NBU DS0002 2004-1.1.5 requires that the monorail meet the 2.5kg dynamic pendulum test. The locking system does not unlock and does not fail. Nissan E87000NDS00 27-1.8.1 requires the second row of seats to meet the low speed of 50km / h, and the luggage compartment...
