[0047] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0048] In the present disclosure, unless otherwise stated, directional words such as “up, down, top, bottom, front, back, left, and right” are generally defined based on the up, down, top, bottom, front, back, left, and right directions of a vehicle in normal driving condition. For example, the direction toward the roof of the vehicle is “up” or “top”, the direction toward the chassis of the vehicle is “down” or “bottom”, the direction toward the front of the vehicle is “front”, the direction toward the rear of the vehicle is “back”, the direction toward the left wheel of the vehicle is “left”, and the direction toward the right wheel of the vehicle is “right” (for details, please refer to Figure 1 、 Figure 3-Figure 7(As shown, where the X direction refers to the front-to-back direction, the Y direction refers to the left-to-right direction, and the Z direction refers to the up-down direction). Directional terms are used solely to facilitate the description of this disclosure and simplify the description. They do not indicate or imply that the device or component referred to must have a specific orientation, structure, or operation in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. "Inside" and "outside" refer to the inside and outside of the corresponding component outlines. Furthermore, the terms "first" and "second" are used to distinguish one element from another and do not convey order or importance.

[0049] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed," "connected," "connected," and "installed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections, and may be directly connected or indirectly connected through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.

[0050] like Figures 1 to 11 As shown, according to the first aspect of the present disclosure, a mounting base 100 is provided, including a base body 40, wherein the base body 40 is formed with a receiving cavity 30, and the receiving cavity 30 is suitable for receiving at least part of the vehicle sensing component 200 of the seat belt retractor 2000, and the base body 40 is provided with a sewage discharge structure 10, which can discharge the pollutants in the receiving cavity 30 and can prevent the pollutants from entering the receiving cavity 30 from the sewage discharge structure 10 to at least a certain extent.

[0051] It is understandable that if Figure 1 and Figure 5 As shown, in the design of the seatbelt retractor 2000, since the brake lever 230 and the ratchet 2110 on the belt reel 2100 need to be selectively engaged to lock the belt reel 2100, the housing of the vehicle sensing device 1000 must be provided with a notch 310 to provide space for the brake lever 230 to move. External contaminants may fall into the vehicle sensing device 1000 through the notch 310. Under the action of gravity, the contaminants may slide from the ball socket surface 221 to the vicinity of the contact point between the spherical mass body 210 and the ball seat 220. During the process of the spherical mass body 210 moving from the normal position to the locked position, the presence of the contaminants may cause the brake lever 230 to rotate at a greater angle. In other words, the locking of the retractor 2000 is more sensitive to a given inertial force, making it prone to false locking. If the size of the contaminants exceeds a certain critical value, the movement of the spherical mass body 210 is restricted under the action of the given inertial force, resulting in an inability to rotate the brake lever 230 and thus an inability to lock.

[0052] In the related art, an opening is provided on the ball seat of the spherical mass body so that the pollutants fall under the action of gravity and are discharged. However, the discharged pollutants will fall into the shell of the vehicle sensing device. During the driving of the vehicle, the pollutants will rebound due to vibration and enter the ball seat again, causing the vehicle sensing device to be locked incorrectly or unable to be locked.

[0053] In the technical solution disclosed in this disclosure, Figure 1 and Figure 5 As shown, the pollutants in the accommodating cavity 30 can be discharged through the sewage discharge structure 10. Therefore, the pollutants that fall into the accommodating cavity 30 can be discharged through the sewage discharge structure 10 set on the base body 40, thereby avoiding the presence of pollutants affecting the normal operation of the vehicle sensing component 200, that is, avoiding the presence of pollutants causing the vehicle sensing component 200 to be locked incorrectly, or causing the vehicle sensing component 200 to be unable to be locked, and the sewage discharge structure 10 can at least to a certain extent prevent pollutants from entering the accommodating cavity 30 from the sewage discharge structure 10, that is, it can at least to a certain extent prevent discharged pollutants and / or pollutants originally located outside the accommodating cavity 30 from entering the accommodating cavity 30 from the sewage discharge structure 10, or, in other words, the sewage discharge structure 10 can prevent at least part of the pollutants from entering the accommodating cavity 30 from the sewage discharge structure 10, thereby further improving the pollutant discharge effect of the sewage discharge structure 10, thereby improving the operating reliability of the vehicle sensing device 1000, and further improving the safety of the vehicle.

[0054] In some embodiments of the present disclosure, Figure 1 As shown, the sewage discharge structure 10 includes an opening portion 11 and a shielding portion 12. The opening portion 11 is provided on the first wall 20 of the base body 40 and passes through the first wall 20 for discharging pollutants in the accommodating cavity 30. The shielding portion 12 shields at least part of the opening portion 11 to prevent at least part of the pollutants from entering the accommodating cavity 30 through the opening portion 11.

[0055] An opening portion 11 penetrating the first wall 20 is provided on the first wall 20 of the base body 40 to discharge pollutants, and the shielding portion 12 shields at least part of the opening portion 11, thereby preventing pollutants from rebounding under the action of vibration, etc., and thus entering the accommodating cavity 30 from the opening portion 11 in the opposite direction. The structure is simple, reliable and low-cost.

[0056] In some embodiments of the present disclosure, Figure 2 As shown, the opening portion 11 includes a first end 111 and a second end 112 opposite to each other in the extension direction of the opening portion 11, the first end 111 is located on the inner wall of the first wall 20, and the second end 112 is located on the outer wall of the first wall 20. Along the vertical direction, the projection of the shielding portion 12 on the outer wall of the first wall 20 is suitable for at least partially covering the second end 112 of the opening portion 11.

[0057] It is understandable that if Figure 2As shown, the z direction is the vertical direction, the accommodating chamber 30 is located above the sewage discharge structure 10, and the second inner wall 22 forming the opening portion 11 is formed as the shielding portion 12. Since the projection of the shielding portion 12 on the first wall 20 along the vertical direction is suitable for at least partially covering the second end 112 of the opening portion 11, when the pollutants fall through the opening portion 11, they may rebound under the action of vibration, that is, the pollutants jump upward from the second end 112 of the opening portion 11. When the pollutants move to the position of the shielding portion 12, they are blocked by the shielding portion 12 and fall again, thereby preventing at least part of the pollutants from entering the accommodating chamber 30 from the sewage discharge structure 10, that is, preventing the pollutants from entering the accommodating chamber 30 from the sewage discharge structure 10 to a certain extent.

[0058] In some embodiments of the present disclosure, Figure 2 As shown, along the vertical direction, the projection of the shielding portion 12 on the outer wall of the first wall 20 is adapted to completely cover the second end 112 of the opening 11. As a result, pollutants jumping upward from the second end 112 of the opening 11 can be substantially blocked by the shielding portion 12, thereby preventing the vast majority of pollutants from entering the accommodating cavity 30 through the sewage discharge structure 10, further improving the sewage discharge effect.

[0059] In some embodiments of the present disclosure, Figure 2 、 Figure 7 、 Figure 8 and Figure 9 As shown, the first wall 20 includes a first inner wall 21 and a second inner wall 22 forming the opening portion 11 , at least one of the first inner wall 21 and the second inner wall 22 is inclined, and the inclined first inner wall 21 and / or second inner wall 22 forms the shielding portion 12 .

[0060] It is understandable that if Figure 2 As shown, the first inner wall 21 and the second inner wall 22 forming the opening 11 are both inclined, and the inclination direction is consistent. At this time, since the second inner wall 22 can block at least part of the opening 11, the inclined second inner wall 22 forms the blocking portion 12. Figure 7 As shown, the first inner wall 21 forming the opening 11 is vertical, and the second inner wall 22 is inclined. At this time, the second inner wall 22 can block at least part of the opening 11, so the inclined second inner wall 22 forms the blocking portion 12. Figure 8 As shown, the first inner wall 21 and the second inner wall 22 forming the opening 11 are both inclined, and the inclination directions are opposite. At this time, since the first inner wall 21 and the second inner wall 22 can both block at least part of the opening 11, the inclined first inner wall 21 and the second inner wall 22 both form the blocking portion 12. Figure 9 As shown, the opening of the sewage discharge structure 10 is formed by four inner walls, and the two inner walls located at the lower side block part of the opening 11, so the two inner walls form the blocking part 12.

[0061] It is understandable that the sewage discharge structure 10 is not limited to this. As long as there is an opening 11 that can discharge pollutants, the shielding portion 12 that can block at least part of the opening 11 can prevent pollutants from entering the accommodating cavity 30 through the opening 11 to at least a certain extent.

[0062] In some embodiments of the present disclosure, Figure 2 As shown, the first inner wall 21 and the second inner wall 22 are both inclined, and the inclination direction is consistent. In the vertical direction, a portion of the second inner wall 22 is adapted to overlap the first inner wall 21, and the second inner wall 22 forms a shielding portion 12. Since the second inner wall 22 partially overlaps the first inner wall 21, in the vertical direction, the second inner wall 22 completely covers the opening 11, forming the shielding portion 12. As a result, pollutants that jump upward from the opening 11 can basically be blocked by the shielding portion 12, thereby preventing the vast majority of pollutants from entering the accommodating chamber 30 through the sewage discharge structure 10, further improving the sewage discharge effect.

[0063] In some embodiments of the present disclosure, Figure 1 As shown, the sewage discharge structure 10 is suitable for being arranged on the bottom wall of the accommodating chamber 30. By arranging the sewage discharge structure 10 on the bottom wall of the accommodating chamber 30, it is more conducive to the discharge of pollutants from the accommodating chamber 30 under the action of gravity.

[0064] In some embodiments of the present disclosure, Figure 1 As shown, the sewage discharge structure 10 is adapted to be disposed opposite to the brake arm 231 of the vehicle sensing assembly 200 .

[0065] It can be understood that the brake arm 231 engages with the ratchet 2110 on the retractor 2000 through the notch 310 provided on the outer shell of the vehicle sensing device 1000, that is, the brake arm 231 is arranged opposite to the notch 310, and the pollutants mainly enter the accommodating chamber 30 through the notch 310. By arranging the sewage discharge structure 10 and the brake arm 231 opposite to each other, the pollutants can reach the sewage discharge structure 10 more quickly after entering through the notch 310, and thus be discharged from the sewage discharge structure 10 more quickly, thereby improving the sewage discharge efficiency.

[0066] In some embodiments of the present disclosure, Figure 1 and Figure 2 As shown, the base body 40 includes a snap-fit ​​structure 41, which is adapted to snap-fit ​​with the ball seat 220 of the vehicle sensor assembly 200. By providing the snap-fit ​​structure 41, the assembly of the vehicle sensor assembly 200 is more convenient.

[0067] In some embodiments of the present disclosure, Figure 1 and Figure 2As shown, the clamping structure 41 is a groove or a protrusion. The concave-convex clamping matching method is simple, reliable and easy to process.

[0068] In some embodiments of the present disclosure, Figure 10 As shown, the bottom wall of the accommodating cavity 30 is provided with a spherical socket surface 221, and the spherical mass body 210 of the vehicle sensing assembly 200 is suitable for being placed in the spherical socket surface 221. It can be understood that in this embodiment, the mounting base 100 and the ball seat 220 are integrated into the design, thereby improving the integration of the vehicle sensing device 1000.

[0069] According to a second aspect of the present disclosure, a vehicle sensing device 1000 is provided. The vehicle sensing device 1000 includes the mounting base 100 of the aforementioned embodiment. Therefore, the vehicle sensing device 1000 includes all the technical effects of the mounting base 100 of the aforementioned embodiment. Since the technical effects of the mounting base 100 have been described in detail above, they will not be repeated here.

[0070] In some embodiments of the present disclosure, Figure 3 and Figure 4 As shown, the vehicle sensing assembly 200 includes a spherical mass body 210, a brake rod 230 and a ball seat 220. The brake rod 230 can lock the belt reel 2100 under the action of the spherical mass body 210. The ball seat 220 is arranged in the accommodating cavity 30. The ball seat 220 has a ball socket surface 221. The spherical mass body 210 is suitable for being placed on the ball socket surface 221. The ball seat 220 has an opening structure 222.

[0071] By providing an opening structure 222 on the ball seat 220, pollutants that fall onto the ball seat 220 can be discharged through the opening structure 222, thereby preventing pollutants from accumulating on the ball seat 220. In this way, the pollutants are prevented from affecting the movement of the spherical mass body 210, thereby preventing mislocking or failure to lock, which affects the reliability of the vehicle sensing device 1000.

[0072] In some embodiments of the present disclosure, Figure 5 As shown, the vehicle sensing device 1000 also includes a shell 300, the vehicle sensing component 200 and the mounting base 100 are both arranged in the shell 300, the shell 300 includes a notch 310, the brake rod 230 is suitable for locking and cooperating with the tape reel 2100 through the notch 310, and the opening structure 222 is arranged opposite to the notch 310.

[0073] By arranging the opening structure 222 relative to the notch 310, pollutants entering from the notch 310 can be discharged from the opening structure 222 more quickly, thereby reducing pollutants falling into other parts of the ball seat 220, and preventing pollutants from moving to the part where the spherical mass body 210 and the ball seat 220 cooperate under the influence of vibration, etc., thereby affecting the reliability of the vehicle sensing device 1000.

[0074] In some embodiments of the present disclosure, Figure 5 As shown, the opening structure 222 is arranged opposite to the sewage discharge structure 10 .

[0075] By arranging the opening structure 222 relative to the sewage discharge structure 10, the pollutants discharged from the opening structure 222 can be discharged from the accommodating cavity 30 more quickly through the sewage discharge structure 10, thereby preventing the pollutants from falling into other parts of the accommodating cavity 30, thereby preventing the pollutants from re-entering the ball seat 220 from the opening structure 222 under the influence of vibration, etc., thereby affecting the reliability of the vehicle sensing device 1000.

[0076] In some embodiments of the present disclosure, Figure 10 and Figure 11 As shown, the vehicle sensing assembly 200 includes a spherical mass body 210 and a brake rod 230. The brake rod 230 can lock the belt reel 2100 under the action of the spherical mass body 210. The bottom wall of the accommodating cavity 30 is provided with a spherical socket surface 221. The spherical mass body 210 of the vehicle sensing assembly 200 is suitable for being placed on the spherical socket surface 221.

[0077] It is understood that in this embodiment, a ball socket surface 221 is directly provided on the bottom wall of the accommodating cavity 30 to accommodate the spherical mass body 210. In this way, the ball seat 220 can be omitted, that is, the ball seat 220 is directly integrated with the mounting base 100, thereby improving the integration of the vehicle sensing device 1000. It is understood that in this case, the sewage structure 10 can be directly provided on the ball socket surface 221 and arranged opposite to the notch 310 on the housing 300 described above, so that pollutants entering through the notch 310 can be quickly discharged from the sewage structure 10; of course, the mounting base 100 can also be configured as follows. Figure 10 and Figure 11 As shown, a spherical socket surface 221 is provided on the bottom wall of the accommodating cavity 30, and an opening structure 222 is provided on the spherical socket surface 221. The opening structure 222 is arranged opposite to the notch 310 provided on the shell 300, that is, the opening structure 222 is arranged below the notch 310 on the shell 300, and a sewage discharge structure 10 is correspondingly provided on the structure below the opening structure 222, that is, the opening structure 222 and the sewage discharge structure 10 are also arranged opposite to each other. In this way, the pollutants entering from the notch 310 quickly fall through the opening structure 222 and are quickly discharged through the sewage discharge structure 10, reducing the residence of pollutants in the accommodating cavity 30, and at the same time avoiding the pollutants discharged from the sewage discharge structure 10 from rebounding into the accommodating cavity 30 under vibration and the like, thereby affecting the operation reliability of the vehicle sensing device 1000.

[0078] According to a third aspect of the present disclosure, the present disclosure further provides a retractor 2000 , which includes the vehicle sensing device 1000 in the above embodiment, or includes the mounting base 100 in the above embodiment.

[0079] It is understandable that if Figure 6 As shown, the retractor 2000 includes a reel 2100 for reeling in the seat belt, and a ratchet 2110 is provided on the reel 2100. The reel 2100 and the vehicle sensing device 1000 are both arranged in a frame structure 2200, and the frame structure 2200 is covered by an outer cover 2300. The retractor 2000 includes all the technical effects of the vehicle sensing device 1000 in the above embodiment or the mounting base 100 in the above embodiment. Since the technical effects of the vehicle sensing device 1000 and the mounting base 100 have been described in detail above, they will not be repeated here.
