Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automobile safety, and specifically relates to a safety belt retractor mounting structure and an automobile. BACKGROUND

[0002] With the rapid progress of the automobile industry and the sweeping wave of intelligentization, automobile technology has not only made remarkable achievements in power, handling, fuel efficiency, etc., but also achieved a qualitative leap in safety performance. Consumers' awareness and demand for automobile safety have expanded from basic protection to a comprehensive and multi-level protection system. Among them, people's requirements for automobile safety performance are indeed increasing. As an important part of automobile safety devices, the stability and reliability of the mounting structure of the safety belt are directly related to the protection effect of the passengers in emergency situations.

[0003] The safety belt retractor mounting structure on the current market, although to some extent, guarantees the basic safety needs of vehicle passengers, but its design limitations are increasingly prominent, especially in the face of complex and variable driving environments. Insufficient connection strength is one of the main problems of this structure, which is directly related to the reliability of the safety belt system in emergency situations. When the vehicle encounters severe bumps or rapid turns, if the connection point of the mounting structure is not strong enough, it may cause the safety belt to loosen or even detach from its original position, which cannot effectively restrain the passengers, thereby increasing the risk of accidents.

[0004] In addition, poor stability is also a defect that cannot be ignored. Under long-term use or harsh conditions, such as high temperature and humid environment, the materials of the mounting structure may age and deform, further weakening its stability. Especially when the passenger or driver violently closes the door, this impact force will be transmitted to the vehicle body through the door, and then impact the mounting structure of the safety belt retractor, which is easy to cause friction or looseness between structural parts, and produce an unpleasant noise. This noise not only destroys the peaceful atmosphere inside the car, but more importantly, it may make passengers question the safety performance of the vehicle, thereby affecting the overall driving experience and trust.

[0005] Secondly, the vehicle will be affected by various dynamic loads and vibrations during driving, such as bumps caused by uneven road surface, vibrations of engine and transmission system, etc. These dynamic loads and vibrations will impact and fatigue the seat belt retractor mounting structure, thereby reducing its stability. The seat belt retractor mounting structure with poor stability cannot effectively restrain the occupant when the vehicle collides, resulting in the collision between the occupant's body and other parts in the vehicle, thereby increasing the risk of injury. In an emergency, if the seat belt retractor mounting structure fails, the occupant may be thrown off the seat belt due to inertia and collide with hard objects in the vehicle, causing secondary injury. Especially when driving on uneven road surface, or encountering sudden situations such as passengers closing the door forcefully, it often leads to loosening of the mounting components, unnecessary noise and shaking, which not only affects the riding experience of the occupant, but also causes anxiety and unease of the occupant. Moreover, the instability of the mounting structure may cause difficulty in adjusting the seat belt, and the occupant may have difficulty in adjusting the tightness and position of the seat belt according to individual needs, thereby affecting the riding comfort. SUMMARY

[0006] The purpose of the present application is to overcome the above problems, and to provide a seat belt retractor mounting structure and a car, which can improve the mounting strength and stability of the seat belt retractor, and reduce shaking and noise.

[0012] Further improvement of the present application is that the retractor is provided with a retractor mounting hole and a buckle, and the buckle is clamped in the clamping groove.

[0013] Further improvement of the present application is that the upper support comprises two curved support arms and a rectangular base, and a first mounting hole is formed in the middle of the rectangular base.

[0014] The further improvement of the present application is that the lower support is a triangular structure, and the edges of the triangular structure are provided with inwardly turned flange structures, one of which is provided with a second mounting hole.

[0015] The further improvement of the present application is that the first mounting hole, the second mounting hole, the third mounting hole and the retractor mounting hole are concentric holes.

[0016] The further improvement of the present application is that the first mounting hole, the second mounting hole and the third mounting hole are fixedly connected with the retractor through bolts.

[0017] The present application also provides an automobile comprising the safety belt retractor structure.

[0018] Compared with the prior art, the present application has the following beneficial effects:

[0019] The present application fixes the mounting structure of the safety belt retractor to the vehicle body through three points by setting the upper support, the lower support and the mounting plate, so that the fixing structure has high connection strength and rigidity, and the stability is improved. The design of the triangular support structure enables the entire mounting structure to evenly disperse stress when subjected to external force, effectively preventing the phenomenon of fracture or deformation caused by stress concentration, improving the stability and reliability of the mounting structure.

[0039] Embodiments

[0040] In view of the problems existing in the safety belt retractor mounting structure mentioned in the background art, such as insufficient connection strength and poor stability, if the connection point of the mounting structure is not strong enough, the safety belt may be loose or even detached from the original position when the vehicle encounters severe bumps or rapid turns, which cannot effectively restrain the passengers, thereby increasing the risk of accidents; poor stability is prone to cause friction or looseness between structural parts, causing unpleasant noise problems, so a new structure needs to be found to solve this problem.

[0041] To solve the above technical problems, the embodiment of the present application provides a safety belt retractor mounting structure and a car.

[0042] As shown in Figure 1 , the embodiment provides a safety belt retractor mounting structure, which comprises an upper bracket 1, a lower bracket 2 and a mounting plate 3, wherein the upper bracket 1 and the lower bracket 2 are fixed through the mounting plate 3, and the upper bracket 1, the lower bracket 2 and the mounting plate 3 are connected together to form a firm support frame, which provides a stable and reliable mounting basis for the safety belt retractor. This stable fixing structure can ensure that the safety belt retractor remains in place without loosening or displacement during vehicle driving, especially in extreme situations such as emergency braking or collision, thereby ensuring the safety of passengers.

[0043] In the embodiment, the upper bracket 1 and the lower bracket 2 are fixedly connected with the mounting plate 3 by welding, which has the advantages of high structural strength, good sealing performance, simple process and high cost-effectiveness.

[0044] In the embodiment, the mounting plate 3 is fixedly connected with the rear side wall column inner plate 6 and the D-pillar inner plate 7 by welding, which can increase the stability and rigidity of the structure, firmly connect the mounting plate 3 with the rear side wall column inner plate 6 and the D-pillar inner plate, and form a more stable overall structure, thereby reducing the risk of deformation and showing higher resistance and stability.

[0045] In the embodiment, as shown in Figure 2 , the upper bracket 1, the lower bracket 2 and the mounting plate 3 are fixed with the vehicle body to form a triangular support 12. The triangular support structure makes the stress between the upper bracket 1, the lower bracket 2 and the mounting plate 3 more uniform, avoiding local damage caused by excessive stress at a single point, thereby prolonging the service life of the parts. Moreover, the stable support structure can reduce noise and discomfort caused by loosening or vibration of parts, and improve the ride comfort and NVH (Noise, Vibration and Harshness) performance of the vehicle.

[0046] In the embodiment, as shown in Figure 3As shown, the upper support 1 is located above the mounting plate 3, and the lower support 2 is located below the mounting plate 3. The mounting holes on the upper support 1, the lower support 2, and the mounting plate 3 are coincided, which facilitates the bolt 5 to pass through the coincided mounting holes to fix the retractor 4, and increases the simplicity of connection.

[0047] In this embodiment, as shown in Figure 1 and Figure 4 The upper support 1 includes two curved support arms and a rectangular base. A first mounting hole 11 is formed in the middle of the rectangular base. The two support arms of the upper support 1 are welded and fixed with the rear side pillar inner panel 6. The two curved support arms can disperse and bear forces from different directions, thereby enhancing the support strength of the entire upper support 1. This design makes the upper support 1 more stable when bearing load and less likely to deform or be damaged. The support arms are fixed with the rear side pillar inner panel 6 by welding. The welding connection has the characteristics of high strength, good sealing, and less loosening. Moreover, this design enables the upper support to adapt to the needs of different vehicle models and body structures. By adjusting the bending degree and welding position of the support arms, different installation environments and requirements can be flexibly adapted.

[0048] In this embodiment, as shown in Figure 1 and Figure 5 The lower support 2 is in a triangular structure. An inwardly turned flange structure is arranged on each side of the triangle. A second mounting hole 21 is arranged on one of the flange structures. The first mounting hole 11 and the second mounting hole 21 are symmetrically welded during the welding process, which facilitates the position fixation of the upper support 1 and the lower support 2. At the same time, the bolt 5 is inserted into the first mounting hole 11 to fix the retractor 4.

[0049] In this embodiment, as shown in Figure 1 and Figure 6 The upper support 1, the lower support 2, and the mounting plate 3 jointly fix the retractor 4. The mounting plate 3 is provided with a third mounting hole 31 and a clamping groove 32. The retractor 4 is provided with a retractor mounting hole and a buckle. The buckle is clamped in the clamping groove 32, so that the retractor 4 can be doubly fixed with the mounting plate 3, thereby increasing the fixation reliability of the retractor 4 with the mounting plate 3. This design avoids the shaking or abnormal sound of the retractor 4 during vehicle driving. Compared with the original mounting structure without the upper support 1 and the lower support 2, the modal frequency of the retractor 4 is increased by 60%, the dynamic stiffness is increased by 500%, and the vibration sensitivity is decreased by 75%. This design greatly reduces the abnormal sound and strength risk.

[0050] The application will be further explained and described in conjunction with a group of examples and the accompanying drawings as follows:

[0051] As shown in Figure 1 and Figure 2As shown, the upper support 1 and the lower support 2 are fixed by the mounting plate 3, and the upper support 1, the lower support 2 and the mounting plate 3 are fixed with the vehicle body to form a triangular support 12, which can withstand a large external force and disperse the pressure to avoid the risk of structural deformation or collapse. This triangular support 12 structure can significantly enhance the stability and rigidity of the local vehicle body and improve the structural safety of the whole vehicle, providing a stable support structure for the installation of the retractor 4.

[0052] For example, as shown in the drawings, the first mounting hole 11, the second mounting hole 21 and the third mounting hole 31 are arranged in a triangular shape, and the retractor mounting hole is arranged in a concentric circle shape with the first mounting hole 11, the second mounting hole 21 and the third mounting hole 31. Figure 1 As shown, the first mounting hole 11, the second mounting hole 21, the third mounting hole 31 and the retractor mounting hole are concentric circle holes, the first mounting hole 11, the second mounting hole 21 and the third mounting hole 31 are fixedly connected with the retractor 4 through the bolts 5, and the use of multiple mounting holes and bolts 5 increases the number of connection points, thereby improving the rigidity of the overall connection, helping to maintain the stability and reliability of the retractor 4 and its installation components during vehicle driving, and ensuring that the force is evenly distributed between the retractor 4 and the multiple mounting plates to reduce the risk of connection failure caused by excessive force on a single point, while ensuring the alignment of the mounting holes and the tightening of the bolts 5, which can reduce the abnormal noise problem caused by loose connection and improve the ride comfort of the vehicle.

[0053] As shown in the drawings, the first mounting hole 11, the second mounting hole 21 and the third mounting hole 31 are arranged in a triangular shape, and the retractor mounting hole is arranged in a concentric circle shape with the first mounting hole 11, the second mounting hole 21 and the third mounting hole 31. Figure 3 As shown, the upper support 1, the lower support 2 and the mounting plate 3 are made of sheet metal, and the high strength and rigidity characteristics of the sheet metal material enable the retractor 4 and the mounting plate 3 to maintain a stable posture and position during vehicle driving, and are not prone to deformation or loosening, which helps to ensure the normal operation of the safety belt retractor 4 and the safety of passengers.

[0054] In summary, the present embodiment provides a safety belt retractor mounting structure which not only enables the safety belt retractor to be stably fixed on the triangular support structure, but also effectively reduces the shaking or abnormal noise of the safety belt retractor during vehicle driving, providing a more safe and comfortable driving environment for passengers.

[0055] The present embodiment also provides an automobile with a safety belt retractor mounting structure, which enables the safety belt retractor mounting structure to be stably fixed on the triangular support structure, effectively improving the stability and strength of the entire mounting structure, dispersing the impact force and vibration that may occur during vehicle driving, and providing a more solid protective barrier for passengers in emergency situations or severe driving.

[0056] In summary, the present application provides a safety belt retractor mounting structure which has the following advantages compared to existing safety belt retractor mounting structures:

[0057] The safety belt retractor mounting structure of the present application, by adopting the design of a triangular support structure, connects the upper support 1, the lower support 2 and the mounting plate 3 with the rear side wall column inner plate 6 and the D-pillar inner plate 7 respectively, forming a triangular support 12, effectively improving the stability and strength of the entire mounting structure, this structure can evenly disperse stress, prevent stress concentration, thereby enhancing the impact resistance of the mounting structure.

[0058] Secondly, the mounting structure of the present application can more effectively fix the safety belt retractor 4, by enhancing the stability and strength of the mounting structure, effectively reducing the safety hazards caused by the failure of the mounting structure, improving the safety protection of the occupants in emergency situations; at the same time, by reducing the shaking and abnormal sound, the driving experience of the occupants is improved, making the driving process more stable and comfortable.

[0059] In addition, by adopting high-strength, corrosion-resistant materials and optimized structural design, the mounting structure of the present application can maintain stable performance in long-term use, reduce damage caused by factors such as vibration and wear, prolong the service life, accurately control the installation position and angle, reduce the deviation of the safety belt path caused by improper installation of the retractor 4, avoid the discomfort or interference of the safety belt to the passengers during use, and adapt to the installation requirements of safety belt retractors 4 of different models and different positions, improving the versatility and flexibility of the product.

[0060] In summary, the safety belt retractor mounting structure provided by the present application has significant advantages in safety, installation convenience, riding comfort, durability and adaptability, etc., not only solves the problems of insufficient connection strength and poor stability of the rear-row safety belt retractor mounting structure, but also improves the retractor 4 modal, improves the dynamic stiffness of the mounting point, reduces the sensitivity of the mounting point, and improves the overall safety of the automobile and the user experience.
