A webbing retractor device 100 according to an embodiment of the present invention, as shown in fig. 1, includes: frame 1, reel 2 and at least one lock housing 41. The frame 1 includes a back plate 13 and two support plates 10, the two support plates 10 are respectively a first support plate 11 and a second support plate 12, the two support plates 10 are spaced apart and arranged parallel to each other, the back plate 13 is connected between the two support plates 10, the two support plates 10 are respectively provided with corresponding through holes 16, and at least one of the through holes 16 is a ratchet hole 161. The winding shaft 2 is pivotably arranged between two support plates 10, the winding shaft 2 being provided with two cover discs 3 spaced apart in the axial direction thereof, the two cover discs 3 being arranged adjacent to a first support plate 11 and a second support plate 12, respectively, each cover disc 3 covering a respective through hole 16 in an orthographic projection on the respective support plate 10. In the example of fig. 2, the two cover discs 3 are a first cover disc 31 and a second cover disc 32, respectively, the first cover disc 31 being adjacent to the first support plate 11 and the second cover disc 32 being adjacent to the second support plate 12. The lock holders 41 are provided on the respective cover plates 3, the lock holders 41 are inserted into the respective ratchet holes 161, the lock holders 41 are provided with the locking pawls 42, and the locking pawls 42 are provided with ratchet teeth 421 adapted to engage with the respective ratchet holes 161 to prevent the spool 2 from rotating in the webbing-withdrawing direction.
Specifically, the reel 2 is used for winding a safety belt (not shown), the rotation of the reel 2 drives the pulling out or retracting of the safety belt, the two ends of the reel 2 are respectively provided with an output shaft 6, the two output shafts 6 are respectively a first output shaft 61 and a second output shaft 62, each output shaft 6 is coaxially arranged with the pivot axis of the reel 2, and the output shafts 6 extend out from the corresponding through holes 16 on the two support plates 10.
Because the two ends of the reel 2 are respectively provided with the covering disc 3, when the reel 2 winds the safety belt, the covering disc 3 can also prevent the safety belt from deviating on the reel 2, and even can avoid the situation that the safety belt enters the through hole 16 to cause the abnormal locking of the safety belt winding device 100.
The number of the locking seats 41 may be one or two, when there is one locking seat 41, the number of the locking claws 42 is one, and the through hole 16 of the support plate 10 matched with the locking seat 41 is the ratchet hole 161. When the lock holder 41 is two, the locking pawl 42 is also two, and the through holes 16 of the two support plates 10 are both ratchet holes 161.
The belt retractor 100 further comprises an end cap assembly 7, the end cap assembly 7 being disposed on the frame 1 to support and protect components on the belt retractor 100. The end cap assembly 7 includes a first end cap assembly 71 and a second end cap assembly 72, the first end cap assembly 71 is disposed on the first support plate 11, the first output shaft 61 is rotatably supported on the first end cap assembly 71, and the first cover plate 31 cooperates with the first support plate 11 and the first end cap assembly 71 to form a sealed space. A first end cap assembly 71.

In addition, the seat belt retractor 100 further includes an emergency lock mechanism 8(ELR) and the like, the emergency lock mechanism 8 being provided between the support plate 10 and the corresponding head cover assembly 7, and the emergency lock mechanism 8 may include a vehicle-feel device 82, a belt-feel device 81, and the like. The belt sensing device 81 detects an abnormal belt withdrawal acceleration and triggers the locking pawl 42 to engage with the corresponding ratchet hole 161, thereby preventing the spool 2 from rotating in the belt withdrawal direction. The vehicle sensing device 82 can detect the inclination angle, acceleration, etc. of the vehicle, and the vehicle sensing device 82 can also trigger the locking pawl 42 to engage the locking pawl 42 with the corresponding ratchet hole 161 when an abnormality is detected, thereby preventing the spool 2 from rotating in the webbing-extracting direction. It should be noted that the structure, operation principle, and the like of the emergency locking mechanism 8 are already known in the art and well known to those skilled in the art, and will not be described in detail here.
Here, the locking pawl 42 has two states of being engaged with the ratchet hole 161 and being disengaged from the inner teeth of the ratchet hole 161 in the ratchet hole 161, so that there is a gap between the spool 2, the locking pawl 42 and the inner peripheral wall of the ratchet hole 161, through which a contaminating particle (such as dust, gravel, etc.) is easily passed between the support plate 10 and the corresponding end cover assembly 7. The contamination particles may interfere with some of the sensing elements in the emergency locking mechanism 8 and affect the sensitivity, stability and reliability of the emergency locking mechanism 8, i.e. the emergency protection function of the seat belt retractor 100 is very much affected by the contamination particles.
In the invention, the cover plates 3 are respectively arranged at the two ends of the scroll 2, so that the cover plates 3 can cover and seal the gap between the scroll 2 and the through hole 16 on the support plate 10, the space between the support plate 10 and the corresponding end cover assembly 7 is a sealed space, and the dustproof effect of the safety belt winding device 100 is improved.

Moreover, since dirt particles are not easily passed through the through-holes 16, the dirt particles are not trapped in the moving member between the support plate 10 and the corresponding end cap assembly 7, reducing the noise of the safety belt retractor 100.
According to the safety belt winding device 100 of the embodiment of the invention, the two cover plates 3 are arranged on the reel 2, so that the through holes 16 in the frame 1 are respectively sealed by the two cover plates 3, the dustproof effect of the safety belt winding device 100 is improved, pollution particles are prevented from influencing the detection precision of the detection element in the safety belt winding device 100, the reliability of the safety belt winding device 100 is improved, and the noise of the safety belt winding device 100 is also reduced. In addition, the arrangement of the covering disc 3 can prevent the safety belt from revolving and deviating on the reel 2, thereby improving the passenger protection performance.
Specifically, as shown in fig. 1 to 4, the cover disk 3 is formed in a disk shape, and the radial dimension of the cover disk 3 is equal to or larger than the root diameter of the corresponding ratchet hole 161. Thus, it is ensured that the orthographic projection of each cover plate 3 on the corresponding support plate 10 covers the corresponding through hole 16, and the cover plates 3 are simple in structure and easy to machine.
More specifically, the two cover disks 3 extend outward from the spool 2 in the radial direction thereof, i.e., the two cover disks 3 are provided on the spool 2 and extend in the axial direction away from the spool 2.

Thus, when the emergency locking mechanism 8 detects the vehicle running abnormality, the emergency locking mechanism 8 can be engaged with one of the braking pawls 42, and when the emergency locking mechanism 8 drives the braking pawl 42 to move, the other braking pawl 42 simultaneously brakes the spool 2 by the driving of the transmission rod 43, thereby simplifying the structure of the webbing retractor 100.
Specifically, the reel 2 is provided with a through hole 21 extending in the axial direction thereof, a transmission rod 43 is provided in the through hole 21, and both ends of the transmission rod 43 protrude from the through hole 21 and are connected to the locking pawls 42 through the cover plate 3.
