Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to a mounting bracket and a vehicle. Background Technology

[0002] The seat belt retractor is the core component of the seat belt. It is used to retract the webbing. The retractor can automatically release or retract the webbing according to the occupant's movements to ensure that the webbing fits the occupant's body, neither too tight nor too loose.

[0003] Vehicle pillars typically have mounting plates on them, and the seatbelt retractor is mounted on these plates to secure it to the pillar. However, the mounting plates are usually cantilevered and welded to the pillar. This means that when the mounting plate is subjected to the force of the retractor, most of the stress is concentrated at the weld point. In the event of a collision or other accident, this can lead to deformation or tearing of the mounting plate, negatively impacting the reliability of the seatbelt. Utility Model Content

[0004] In view of this, this application aims to provide a mounting bracket to improve the reliability of seat belts.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A mounting bracket for mounting a seatbelt retractor to a vehicle pillar, the mounting bracket including a bracket body for mounting the seatbelt retractor, and a connecting portion disposed on a first side of the bracket body, the mounting bracket being connected to the vehicle pillar through the connecting portion; From the first side of the bracket body to the second side of the bracket body away from the vehicle pillar, the size of the bracket body gradually decreases in the first direction.

[0006] Furthermore, a cavity is formed between the main body of the support and the vehicle pillar, and the upper part of the cavity is open.

[0007] Furthermore, the main body of the support includes two side plates and a bottom plate connected between the two side plates. The two side plates and the bottom plate are arranged in pairs and enclose the cavity. The side panel of one of them is provided with a mounting part for installing the seat belt retractor.

[0008] Furthermore, the projection of the cavity onto the horizontal plane is triangular.

[0009] Furthermore, the connecting portion includes a first flange disposed on both sides of the support body along the first direction, and a second flange located at the lower part of the first side of the support body; The first flanges on both sides are connected to the two side plates respectively, the second flanges are connected to the bottom plate, and the two first flanges and the second flanges are connected to the vehicle pillars respectively.

[0010] Furthermore, the base plate is provided with an upwardly bent third flange, which overlaps and connects with at least one of the side plates.

[0011] Furthermore, an anti-rotation part is provided on the side plate where the mounting part is provided. The anti-rotation part is plugged into and connected to the seat belt retractor, which can prevent the seat belt retractor from rotating relative to the mounting bracket.

[0012] Furthermore, each of the first flanges extends along the height direction of the vehicle pillar.

[0013] Furthermore, the second flange extends along the first direction.

[0014] Furthermore, at least one of the two side plates and the bottom plate is provided with a wire harness mounting hole.

[0015] Furthermore, at least one of the two side plates and the bottom plate is provided with a positioning part, which is used to define the installation position of the mounting bracket on the vehicle pillar.

[0016] Compared with related technologies, this application has the following advantages: (1) The mounting bracket described in this application, by setting a bracket body and a connecting part, connects the connecting part to the vehicle pillar, installs the seat belt retractor on the bracket body, and makes the size of the bracket body decrease from the first side to the second side in the first direction, so that the bracket body can form a relatively stable structure. When the bracket body is subjected to the force from the seat belt retractor, the stress generated is dispersed on the bracket body and then transmitted to the pillar through the connecting part, and finally transmitted to the vehicle body through the pillar to dissipate and decompose the stress. The mounting bracket has a strong load-bearing capacity and is not prone to deformation or tearing, which is conducive to improving the reliability of seat belt use.

[0017] (2) A cavity is formed between the main body of the support and the column, which can form an installation space for the safety belt retractor. At the same time, it can combine the main body of the support and part of the column to form a box-shaped structure, which is conducive to enhancing the structural strength of the main body of the support and making the main body of the support stronger.

[0018] (3) The main body of the support adopts two side plates and the bottom plate intersecting each other, which can form a relatively stable three-dimensional box-shaped frame structure. The safety belt retractor is installed on the side plate. When the side plate is subjected to the force of the safety belt retractor, it can be well transmitted to the other side plate and the bottom plate, and has a good force transmission effect.

[0019] (4) The cavity is triangular in shape on the horizontal plane. It can utilize the stability of the triangle to enhance the overall strength of the frame structure composed of the two side plates, the bottom plate and the column side walls, so that the main body of the support is not easily deformed when subjected to external forces.

[0020] (5) Arrange a first flange connected to the column on the side plate and a second flange connected to the column on the bottom plate. This can form two force transmission paths of side plate, first flange and column, and one force transmission path of bottom plate, second flange and column, which enriches the force transmission path of the mounting bracket and makes the mounting bracket more stable.

[0021] (6) A third flange that bends upward is provided on the base plate, and the third flange is connected to at least one side plate, which helps to improve the connection strength between the base plate and the side plate and improve the deformation resistance of the mounting bracket.

[0022] (7) An anti-rotation part is provided on the side plate with the installation part. The anti-rotation part is inserted into the seat belt retractor, which makes it difficult for the seat belt retractor to rotate during installation and facilitates the assembly of the seat belt retractor.

[0023] (8) The first flange extends along the height direction of the vehicle pillar, which can make the contact area between the first flange and the vehicle pillar larger, enhance the connection strength between the two, and improve the impact resistance of the mounting bracket; the second flange extends along the first direction, which can make the contact area between the second flange and the vehicle pillar larger, enhance the connection strength between the two, and improve the impact resistance of the mounting bracket.

[0024] (9) A wire harness mounting hole is provided on at least one of the two side plates and the bottom plate, which can provide a channel for the wire harness to pass through the mounting bracket and also serve as a positioning function for the wire harness, thus facilitating the routing of the wire harness in the vehicle; a positioning part is provided on at least one of the two side plates and the bottom plate, which can provide positioning for the mounting bracket when it is assembled to the column, thus improving the installation position accuracy of the mounting bracket.

[0025] Another object of this application is to provide a vehicle having the aforementioned mounting bracket.

[0026] The vehicle described in this application, by setting the aforementioned mounting bracket on the pillar, can provide a stable and reliable mounting base for the vehicle's seat belt retractor. This ensures that in emergency scenarios such as sudden braking and collisions, the mounting bracket can quickly disperse the stress transmitted from the seat belt retractor to the pillar, and the pillar can then transfer the stress to the vehicle body for dissipation and decomposition. The mounting bracket is not easily deformed, and the seat belt retractor can perform its locking function normally, effectively restraining the occupant's body, reducing the risk of injury or death, and improving the overall vehicle safety performance.

[0028] To make the technical solution and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0032] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0034] An embodiment of the first aspect of this application provides a mounting bracket to improve the reliability of seat belt use.

[0035] The retractor of a vehicle seatbelt is the core component of the seatbelt. It is used to retract the webbing of the seatbelt. The retractor can automatically release or retract the webbing according to the occupant's movements, ensuring that the webbing fits the body, neither too tight nor too loose, so as to provide a relatively comfortable wearing experience while ensuring restraint and protection of the occupant's body.

[0036] In related technologies, the installation method for seat belt retractors usually involves setting up a mounting plate on the vehicle pillar. One end of the mounting plate is raised and has a hole. The seat belt retractor is assembled onto the mounting plate through the hole, thereby fixing the retractor relative to the pillar.

[0037] However, this type of mounting plate has a cantilever structure, with one end welded to the pillar and the other end connected to the seat belt retractor. This means that when the mounting plate is subjected to the force of the seat belt retractor, most of the stress on the mounting plate is concentrated at the welded position to the pillar. In the event of a collision or other accident, the mounting plate is prone to deformation or tearing. In severe cases, it may even cause the seat belt retractor to fall off, which is not conducive to improving the reliability of the seat belt.

[0038] In view of this, in order to overcome the shortcomings of the related technology, the mounting bracket in this embodiment combines... Figures 1 to 3 In terms of overall design, it is used to install the seat belt retractor 4 on the vehicle pillar 3 and to install the seat belt retractor 4. It also includes a bracket body 1 and a connecting part 2 located on the first side 108 of the bracket body 1. The bracket is connected to the vehicle pillar 3 through the connecting part 2.

[0039] Specifically, from the first side 108 of the support body 1 to the second side 107 of the support body 1 away from the vehicle pillar 3, the size of the support body 1 gradually decreases in the first direction. It should be noted that the direction from the first side 108 to the second side 107 is also the second direction, wherein the first direction and the second direction intersect, and in a preferred embodiment, the first direction and the second direction are orthogonal.

[0040] Therefore, by setting up a bracket body 1 and a connecting part 2, connecting the connecting part 2 to the vehicle pillar 3, and installing the seat belt retractor 4 on the bracket body 1, and making the size of the bracket body 1 gradually decrease from the first side 108 to the second side 107 in the first direction, the bracket body 1 can form a relatively stable structure. When the bracket body 1 is subjected to the force from the seat belt retractor 4, the stress generated is dispersed on the bracket body 1 and then transmitted to the pillar 3 through the connecting part 2, and finally transmitted to the vehicle body through the pillar 3 to dissipate and decompose the stress. The mounting bracket has a strong load-bearing capacity and is not prone to deformation or tearing, which helps to improve the reliability of seat belt use.

[0041] Meanwhile, the intersection of the first and second directions enables the main body 1 of the bracket to form a variable cross-section structure, which is beneficial to improving the bending and torsional resistance of the mounting bracket. In extreme scenarios such as sudden braking and collisions of vehicles, it can reduce the risk of damage to the mounting bracket caused by stress concentration and ensure the stability of the seat belt retractor 4.

[0042] Based on the above general introduction, specifically, the second side 107 of the support body 1 can be the side away from the side wall of the column 3. Correspondingly, the first side 108 of the support body 1 is the side close to the side wall of the column 3. The second direction is the direction from the second side 107 of the support body 1 to the side wall of the column 3. The first direction is the extension direction of the first side 108 of the support body 1 on the side wall of the column 3, and the height direction is the extension direction of the column 3.

[0043] In this way, when the webbing 5 is pulled and the support body 1 is subjected to the force of the seat belt retractor 4, the stress can be transmitted along the second direction. Along the transmission path, the cross-sectional size of the support body 1 gradually increases, which can distribute the stress more evenly and transmit it to the column 3 through the connecting part 2, so as to reduce the stress concentration.

[0044] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, a cavity a is formed between the support body 1 and the vehicle pillar 3, and the upper part of the cavity a is open.

[0045] In this way, the cavity a is formed between the main body 1 and the column 3, which provides an installation space for the seat belt retractor 4. Simultaneously, it allows the main body 1 and part of the side wall of the column 3 to combine to form a box-like structure, which enhances the structural strength of the main body 1 and increases its load-bearing capacity. Furthermore, arranging the cavity a as an open-top form reduces material usage without excessively weakening the structural strength of the main body 1, thus achieving a lightweight installation bracket and saving production costs.

[0046] It is understandable that the cavity a formed between the bracket body 1 and the vehicle pillar 3 can also be open downwards or open to the side, both of which can play a role in weight reduction. However, the force transmission effect of the bracket body 1 is worse than that of the open-top form. The bottom wall of the cavity a with the open top has a better force transmission effect.

[0047] Of course, cavity a can also be without an open part, which makes the bracket body 1 and the side wall of the column 3 form a closed box structure. This closed box structure has higher structural strength and is less prone to deformation, but it uses more material, which is not conducive to the lightweight design of the mounting bracket, and may make the connection between the mounting bracket and the seat belt retractor 4 more inconvenient.

[0048] Reference Figures 3 to 5The content, based on the upper open cavity a formed between the support body 1 and the side wall of the column 3, in some exemplary embodiments, the support body 1 includes two side plates 101 and a bottom plate 102 connected between the two side plates 101. The two side plates 101 and the bottom plate 102 are arranged intersecting each other and enclosing the cavity a. One of the side plates 101 is provided with a mounting part 1011 for mounting the seat belt retractor 4.

[0049] With this configuration, the main body 1 of the support frame adopts two side plates 101 and the bottom plate 102 intersecting each other, forming a structure similar to the corner of a box. This is a relatively stable three-dimensional spatial frame structure. Compared with the traditional mounting plate form similar to a flat plate, the main body 1 of the support frame is less prone to deformation when subjected to external forces. The seat belt retractor 4 is mounted on the side plate 101. When the side plate 101 is subjected to the force of the seat belt retractor 4, it can better transmit and disperse the stress to the other side plate 101 and the bottom plate 102, which has a better force transmission effect.

[0050] Based on the support body 1 including two side plates 101 and a base plate 102, in some exemplary embodiments, the projection of cavity a on the horizontal plane is triangular.

[0051] This design, with cavity a forming a triangle on the horizontal plane, leverages the stability of triangles to enhance the overall strength of the frame structure composed of the two side plates 101, the base plate 102, and the side walls of the column 3, making it less prone to deformation when the main body 1 of the bracket is subjected to external forces. Simultaneously, the triangular cross-section of cavity a minimizes the space occupied by the mounting bracket within the vehicle's column 3, saving interior space and contributing to an optimized layout of interior components.

[0052] For the specific arrangement of the mounting bracket cavity a, an example can be found by referring to... Figure 3 , Figure 6 and Figure 7 As shown, the two side plates 101 are connected by an arc-shaped sidewall transition. This arc-shaped sidewall is located at the second side 107 of the mounting bracket. The included angle between the two side plates 101 is D, which ranges from 93° to 97°, preferably 95°. The lengths of the two side plates 101 can be the same or different. When the lengths of the two side plates 101 are the same, the cavity a can form a structure similar to an isosceles triangle, which helps to further improve the structural strength of the bracket body 1.

[0053] Reference Figures 3 to 8As shown, continuing with the bracket body 1 including two side plates 101 and a base plate 102, in some exemplary embodiments, the connecting part 2 includes a first flange 201 disposed on both sides of the bracket body 1 along a first direction, and a second flange 202 located at the lower part of the first side 108 of the bracket body 1. The first flanges 201 on both sides are respectively connected to the two side plates 101, and the second flanges 202 are connected to the base plate 102. The two first flanges 201 and the second flange 202 are respectively connected to the vehicle pillar 3.

[0054] As configured above, a first flange 201 connected to the column 3 is arranged on the side plate 101, which can form a force transmission path of side plate 101-first flange 201-column 3 on both sides of the mounting bracket. A second flange 202 connected to the column 3 is arranged on the bottom plate 102, which can form a force transmission path of bottom plate 102-second flange 202-column 3. This allows the mounting bracket to have multiple force transmission paths in different directions, which is beneficial to improving the stability of the mounting bracket in use.

[0055] Meanwhile, the first flange 201 and the second flange 202 have a good connection effect with the side wall of the column 3. The first flange 201 and the second flange 202 can be set to conform to the shape of the side wall of the column 3, so that the contact area between the first flange 201 and the second flange 202 and the side wall of the column 3 is larger, which is conducive to the rapid transmission of force from the mounting bracket to the column 3.

[0056] Specifically, both the first flange 201 and the second flange 202 can be formed by sheet metal bending. The first flange 201 transitions to the side plate 101 with an arc-shaped sidewall, and the second flange 202 also transitions to the base plate 102 with an arc-shaped sidewall. This improves the integration of the bracket body 1 and the connecting part 2, resulting in higher overall structural strength. Of course, both the first flange 201 and the second flange 202 must avoid interfering with functional structures on the column 3, such as holes or connectors, to ensure the functionality of the column 3.

[0057] Secondly, the first flange 201 and the second flange 202 can be configured to be non-parallel to each other. The non-parallel layout allows the forces borne by each flange to be transmitted to the vehicle pillar 3 in different directions, avoiding the concentration of force transmission direction. This makes the forces transmitted to the pillar 3 more dispersed, which can better distribute the load between the first flange 201 and the side plate 101 and between the second flange 202 and the bottom plate 102, thereby improving the overall connection strength and durability.

[0058] In addition, combined Figures 6 to 8The widths of the first flange 201 and the second flange 202 can both be set to, for example, 13mm. This ensures sufficient welding area with the side wall of the column 3 without being too large and reducing the fit with the column 3. Both the first flange 201 and the second flange 202 can be connected to the side wall of the column 3 by welding, specifically spot welding or perimeter welding, as long as both flanges 201 and 202 are firmly connected to the side wall of the column 3. As for the angle E between the second flange 202 and the base plate 102, E can be set to a value between 85° and 89°. Preferably, E can be set to 87°, which provides good connection strength.

[0059] Reference Figure 4 and Figure 5 As shown, still based on the support body 1 including two side plates 101 and a base plate 102, in some exemplary embodiments, the base plate 102 is provided with an upwardly bent third flange 103, which overlaps and connects with at least one of the side plates 101.

[0060] In this way, by providing an upwardly bent third flange 103 on the base plate 102 and connecting the third flange 103 with at least one side plate 101, a firm connection can be formed between the base plate 102 and the side plate 101, giving the side plate 101 and the base plate 102 better position retention capabilities, which is beneficial to improving the connection strength between the base plate 102 and the side plate 101 and improving the deformation resistance of the mounting bracket.

[0061] Specifically, the third flange 103 can be bent upwards from the base plate 102 using sheet metal bending and welded to a side plate 101. This allows the main body of the bracket 1 to be processed from a single piece of sheet metal, resulting in better integrity after sheet metal and welding. It is important to note that when using welding, release grooves 106 need to be provided at the corners where the two side plates 101 meet the base plate 102 to ensure stress release.

[0062] In detail, the welding method between the third flange 103 and the side plate 101 can be spot welding or peripheral welding, or it can be riveting the third flange 103 to the side plate 101, as long as the connection strength requirements of the third flange 103 and the side plate 101 are met. The connection between the third flange 103 and the side plate 101 is a pre-connection, that is, before the mounting bracket is installed on the column 3, the third flange 103 is already connected to the side plate 101, which helps to save assembly time.

[0063] Reference Figures 2 to 5As shown, continuing on the basis that the bracket body 1 includes two side plates 101 and a base plate 102, in some exemplary embodiments, an anti-rotation part 1012 is provided on the side plate 101 where the mounting part 1011 is provided. The anti-rotation part 1012 is plugged into the seat belt retractor 4 and can prevent the seat belt retractor 4 from rotating relative to the mounting bracket.

[0064] By providing an anti-rotation part 1012 on the side plate 101 with the mounting part 1011, the anti-rotation part 1012 is inserted into the seat belt retractor 4. The anti-rotation part prevents the seat belt retractor 4 from rotating relative to the mounting, making it difficult for the seat belt retractor 4 to rotate during installation, which facilitates the assembly of the seat belt retractor 4.

[0065] Secondly, the relative rotation of the retractor and the mounting bracket will cause friction and wear at the contact points. Long-term use may cause the seat belt retractor 4 to loosen or the outer shell to be damaged. The anti-rotation part 1012 restricts the rotation of the seat belt retractor 4, avoids unnecessary friction, and helps to extend the service life of the seat belt retractor 4 and the mounting bracket.

[0066] Generally, the seatbelt retractor 4 is installed via bolt connection, and it has through holes for the bolts to pass through and anti-rotation holes. For compatible models, please refer to [link / reference]. Figure 4 , Figure 5 and Figure 8 In this embodiment, the mounting portion 1011 on the side plate 101 of the mounting bracket can correspond to the through hole of the seat belt retractor 4. The mounting portion 1011 is set to be partially protruding and has an assembly hole 10111. The seat belt retractor 4 is connected to the side plate 101 by a combination of bolts, nuts and washers.

[0067] As for the anti-rotation part 1012, the side plate 101 can extend outward and be bent to form a hook-shaped structure. The hook-shaped structure passes through the anti-rotation hole to prevent the seat belt retractor 4 from rotating, thereby achieving relative fixation between the seat belt retractor 4 and the mounting bracket. The anti-rotation direction of the anti-rotation part 1012 for the seat belt retractor 4 is the same as the rotatable direction of the bolts used to connect the seat belt retractor 4 and the mounting bracket. There can be more than one anti-rotation part 1012, which is beneficial to enhance the anti-rotation function of the anti-rotation part 1012, but it will correspondingly increase the manufacturing precision requirements. In specific implementation, the number of anti-rotation parts 1012 can be flexibly arranged according to needs.

[0068] Continue to refer to Figures 2 to 5Based on the connection part 2 including a first flange 201 and a second flange 202, in some exemplary embodiments, each first flange 201 extends along the height direction of the vehicle pillar 3. The extension of the first flange 201 along the height direction of the vehicle pillar 3 allows for a larger contact surface between the first flange 201 and the vehicle pillar 3, enhancing the connection strength between them and improving the impact resistance of the mounting bracket.

[0069] Still based on the connection part 2 including the first flange 201 and the second flange 202, in some exemplary embodiments, the second flange 202 extends along a first direction. The extension of the second flange 202 along the first direction allows for a larger contact surface between the second flange 202 and the vehicle pillar 3, enhancing the connection strength between the two and improving the impact resistance of the mounting bracket.

[0070] In addition, to facilitate the routing of wiring harnesses inside the vehicle, in some exemplary embodiments, at least one of the two side panels 101 and the bottom plate 102 is provided with wiring harness mounting holes 104.

[0071] This configuration, with wiring harness mounting holes 104 provided on at least one of the two side plates 101 and the base plate 102, provides a channel for the wiring harness to pass through the mounting bracket, while also serving to position the wiring harness and facilitating wiring harness routing within the vehicle. The wiring harness mounting holes 104 also reduce the weight of the bracket body 1, contributing to a lighter design for the mounting bracket.

[0072] Regarding the positioning method of the mounting bracket and the column 3, in some exemplary embodiments, at least one of the two side plates 101 and the base plate 102 is provided with a positioning part 105, which is used to define the mounting position of the mounting bracket on the vehicle column 3.

[0073] In this way, positioning parts 105 are provided on at least one of the two side plates 101 and the base plate 102, which can provide positioning for the mounting bracket when it is assembled to the column 3, thus improving the installation position accuracy of the mounting bracket.

[0074] For example, refer to Figures 3 to 6The positioning part 105 can be configured as a combination of a main positioning hole 1051 and a secondary positioning hole 1052, both located on the same side plate 101. When assembling the mounting bracket onto the column 3, appropriate tooling is required to be mounted on the column 3. The mounting bracket is then mounted on the tooling, ensuring the main positioning hole 1051 and the secondary positioning hole 1052 mate with the tooling to achieve positioning of the mounting bracket on the column 3. Finally, the first flange 201 and the second flange 202 are welded to the column 3. To reduce the number of openings in the side plate 101, the secondary positioning hole 1052 and the assembly hole 10111 can be combined into one, reducing the processing steps for the mounting bracket.

[0075] In specific implementation, refer to Figure 4 and Figure 5 To further enhance the structural strength of the mounting bracket, the side plate 101 with the mounting part 1011 can be configured as a stepped structure. Specifically, the upper part of the side plate 101 with the mounting part 1011 can be protruding away from the column 3 as a boss 1013. This increases the complexity of the cross-section of the side plate 101, improving its bending and torsional resistance. Alternatively, a reinforcing rib 1014 can be provided along the extension direction of the side plate 101 without the mounting part 1011. The reinforcing rib 1014 protrudes outward away from the column 3 and is located in the middle of the side plate 101. Similarly, this configuration increases the complexity of the cross-section of the side plate 101, improving its bending and torsional resistance.

[0076] In addition, to enhance the overall integrity of the mounting bracket, the side plate 101, bottom plate 102, first flange 201, second flange 202, third flange 103, and anti-rotation part 1012 are made from a single piece of sheet metal, which is then bent into shape. After that, the third flange 103 is welded to the side plate 101, thereby improving the overall structural strength of the mounting bracket.

[0077] Furthermore, the mounting bracket of this embodiment can be used at various seat locations in a vehicle. For the first row of seats, the mounting bracket is installed on the B-pillar; for the second row of seats, it is installed on the C-pillar; and for the third row of seats, it is installed on the D-pillar. Installed at these three locations, the mounting bracket improves the stability of the corresponding seatbelt, demonstrating good versatility.

[0078] It is worth noting that, regarding the mounting bracket of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still provided by... Figures 1 to 8 As shown, it may include, for example, a support body 1 and a first flange 201 and a second flange 202 integrally formed on the support body 1.

[0079] The bracket body 1 is used to install the seat belt retractor 4 and includes two side plates 101 and a bottom plate 102. The bottom plate 102 is bent upward on one side and welded to one of the side plates 101.

[0080] Each of the two side plates 101 is provided with a first flange 201, and the bottom plate 102 is provided with a second flange 202. The first flange 201 and the second flange 202 are both welded to the side wall of the vehicle column 3, so that the bracket body 1 and the side wall of the column 3 form a triangular cavity a.

[0081] One side plate 101 has a wire harness mounting hole 104; the other side plate 101 has an assembly hole 10111 for mounting a seat belt retractor 4, and two anti-rotation parts 1012 bent away from the upright 3, the anti-rotation parts 1012 being inserted into the seat belt retractor 4.

[0082] Among them, the side plate 101, the bottom plate 102, the first flange 201, the second flange 202, the third flange 103 and the anti-rotation part 1012 are formed from a single piece of sheet metal, and then the third flange 103 and the side plate 101 are welded together.

[0083] In the preferred embodiment of the mounting bracket described above, the specific settings and arrangements of the bracket body 1, the first flange 201, the second flange 202, etc. can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the bracket body 1, the first flange 201, and the second flange 202, etc., can also be referred to the descriptions in the above exemplary embodiments.

[0084] The mounting bracket in this embodiment adopts the above design. By setting the bracket body 1 and the connecting part 2, and making the size of the bracket body 1 gradually decrease from the first side 108 to the second side 107 in the first direction, the bracket body 1 can form a relatively stable structure. When the bracket body 1 is subjected to the force from the seat belt retractor 4, the stress generated is dispersed on the bracket body 1 and then transmitted to the column 3 through the connecting part 2. Finally, it is transmitted to the vehicle body through the column 3 to dissipate and decompose the stress. The mounting bracket has a strong load-bearing capacity and is not prone to deformation or tearing, which helps to improve the reliability of seat belt use.

[0085] An embodiment of the second aspect of this application provides a vehicle that is equipped with a mounting bracket according to the embodiment of the first aspect of this application.

[0086] In this embodiment, the vehicle is equipped with a mounting bracket according to the first aspect of this application. This mounting bracket provides a stable and reliable mounting base for the vehicle's seatbelt retractor 4, ensuring that in emergency scenarios such as sudden braking or collisions, the mounting bracket can quickly disperse the stress transmitted from the seatbelt retractor 4 to the pillar 3, and the pillar 3 can then transfer the stress to the vehicle body for dissipation and decomposition. The mounting bracket is not easily deformed, and the seatbelt retractor 4 can perform its locking function normally, effectively restraining the occupant's body, reducing the risk of injury or death, and improving the overall vehicle safety performance.

[0087] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
