Description
Technical field
The utility model belongs to automotive safety facility field, relates generally to a kind of car belt preventing ribbon end locking.
Background technology
Existing car belt is when ribbon is freely recycled to end position, mandrel stops operating suddenly, the ratchet assembly be arranged on mandrel also stops operating suddenly, and the inertial mass now on ratchet assembly has because continuation is rotated around its axis of revolution by effect of inertia, stops until forwarding end position to.Inertial mass engages with the internal tooth of mechanical case when being in end position, triggers the quick lock guide locking mechanism of band, and the final latch that promotes makes the external tooth of latch engage with the internal tooth on framework, and safety strap locking, ribbon cannot pull out.Now need experienced car belt attendant the safety strap of locking could be unlocked, normally use, user is brought inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of car belt preventing ribbon end locking.
The technical solution of the utility model is achieved in that
Prevent a car belt for ribbon end locking, comprise ribbon, taking-up device and ribbon end release mechanism;
Taking-up device comprises framework, case, ratchet and mandrel, and case is fixedly mounted on framework, and ratchet and mandrel are all positioned at case, one end suit ratchet of mandrel, and the external tooth of ratchet coordinates with the internal tooth of case;
Braided strap winding is on the mandrel of taking-up device;
Ribbon end release mechanism is positioned at case, and one end of the suit ratchet of mandrel, ratchet, ribbon end release mechanism match.
Described taking-up device also comprises excentric sleeve, and excentric sleeve is positioned at case, and excentric sleeve is arranged on one end of the suit ratchet of mandrel.
Described ribbon end release mechanism, for separating lock collar, separates the pivot pin free-running fit on circular hole and the mandrel of lock collar, and the locating dowel pin separating lock collar coordinates by separating lock collar spacing hole with ratchet, the centralized positioning shoulder of case and 5 pawls interference fit in the axial direction of solution lock collar.
Beneficial effect:
The utility model solves car belt and likely occurs that when being freely recovered to end position ribbon not easily pulls out problem, ensures car belt working stability, facility, effectively ensures the safety of occupant.Achieve the inertial mass when safety strap is freely recycled to the limit and be unlocked dish suppression rotation, lose latch functions, thus reach the anti-latch functions of end.This structure be do not change in safety strap original structure situation increase a part realize end latch functions, be applicable to the safety strap of all size model, there is commonality good, practical, the features such as this change is little.Be beneficial to and promote the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Prevent a car belt for ribbon end locking, comprise ribbon, taking-up device and ribbon end release mechanism;
As depicted in figs. 1 and 2, taking-up device comprises framework 1, case 2, ratchet 3 and mandrel 6, and case 2 is fixedly mounted on framework 1, and ratchet 3 and mandrel 6 are all positioned at case 2, one end suit ratchet 3 of mandrel 6, and the external tooth of ratchet 3 coordinates with the internal tooth of case 2;
Braided strap winding is on the mandrel 6 of taking-up device;
Ribbon end release mechanism is positioned at case 2, and one end of the suit ratchet 3 of mandrel 6, ratchet 3, ribbon end release mechanism match.
Described taking-up device also comprises excentric sleeve 5, and excentric sleeve 5 is positioned at case 2, and excentric sleeve 5 is arranged on one end of the suit ratchet 3 of mandrel 6.
Described ribbon end release mechanism is for separating lock collar 7, separate the pivot pin free-running fit on the circular hole of lock collar 7 and mandrel 6, the locating dowel pin separating lock collar 7 coordinates by separating lock collar 7 spacing hole with ratchet 3, and centralized positioning shoulder and 5 pawls interference fit in the axial direction of separating lock collar 7 of case 2, form friction force.
Control by the friction force separated between lock collar 7 and case 2 relative position separating inertial mass 8 on lock collar 7 and ratchet 3 in ribbon pull-out with when reclaiming,
When the ribbon of safety strap pulls out, mandrel 6 drives ratchet 3 cw to rotate around mandrel 6 axis, separate lock collar 7 owing to having friction force with the case 2 be fixed on rest frame 1, contact keeping the static spacing hole to ratchet 3 with solution lock collar 7 locating dowel pin, now separate the extreme counterclockwise position of lock collar 7 relative to ratchet 3, afterwards just along with ratchet rotates clockwise together, as shown in Figure 3.Now separate on the motion path of the inertial mass 8 of lock collar 7 not on ratchet 3, inertial mass 8 normally can play the function of band sense locking, does not affect safety strap and normally uses.
When belt-strap reclaims, mandrel 6 drives ratchet 3 left-hand revolution, separate lock collar 7 owing to contacting keeping the static spacing hole to ratchet 3 with solution lock collar 7 locating dowel pin with the friction force between case 2, now separate the extreme clockwise position of lock collar 7 relative to ratchet 3, afterwards just along with ratchet rotates counterclockwise together, as shown in Figure 4.When safety strap be recycled to end position stop suddenly time, whole safety strap stops all immediately except inertial mass 8, inertial mass 8 rotates around its S. A. under the effect of inertia, but because the position of now separating lock collar 7 is just in time on the moving line of inertial mass 8, inertial mass 8 is suppressed to touch the internal tooth engagement of case 2, play and suppress locking effect, realize the appearance preventing end locking phenomenon.If without separating the existence of lock collar 7 in safety strap, inertial mass 8 by when belt-strap is recycled to end position owing to continuing when other parts of the system that acts on of inertia stop to rotate around its S. A., be finally in locking control position.If fruit now inertial mass 8 engages with the internal tooth of case 2 just, namely form guide's locking, belt-strap cannot pull out, and end locking phenomenon occurs.
