Description

Technical Field

[0001] This invention relates to the field of seat belts, and more specifically to a seat belt retractor mounting structure and a vehicle having the mounting structure. Background Technology

[0002] The arrangement of the trunk rack and seats in a sedan determines the trunk capacity and second-row passenger comfort. The retractor for the middle rear seatbelt is usually located in the trunk rack or inside the seat. When the retractor is placed on the seat, the seat frame needs to be strengthened to meet the performance targets of the mounting point, which increases weight and cost.

[0003] However, placing items in the parcel rack area usually encroaches on luggage space.

[0004] Furthermore, the overall structural strength of the mounting bracket for traditional retractors is insufficient, and the installation position of the retractor is unstable.

[0005] The existing patent 202110749603.1 - Package rack assembly for vehicles and vehicles having the same - does not clearly solve the above-mentioned technical problems.

[0030] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0031] A mounting structure for a seatbelt retractor includes a wrapping frame mechanism; the wrapping frame mechanism is equipped with a mounting bracket mechanism. This invention, through the coordinated use of the wrapping frame mechanism and the mounting bracket mechanism, facilitates the subsequent installation and connection of the seatbelt retractor 6 onto the vehicle body. Simultaneously, through the coordinated use of the wrapping beam, mounting plate 5, and support plate 3, the overall mounting structure for the seatbelt retractor forms a triangular structure, effectively ensuring the overall structural strength of the mounting structure and contributing to the stability of the seatbelt retractor 6 during installation on the vehicle.

[0032] This invention discloses an installation structure for a seat belt retractor; the installation structure disclosed in this invention is mainly used for the installation of the seat belt retractor 6; essentially it is a mounting bracket structure.

[0033] In this invention, the mounting structure for the seatbelt retractor includes a wrap-around frame mechanism; the wrap-around frame mechanism is provided with a mounting bracket mechanism; in this invention, the wrap-around frame mechanism is part of the vehicle body structure, and the setting of the wrap-around frame mechanism facilitates the installation and connection of the mounting structure on the vehicle body.

[0034] Specifically, the package frame mechanism in this invention includes a package beam, which is essentially a crossbeam structure, facilitating the arrangement and connection of the installation structure. In this invention, the package beam includes a package frame upper crossbeam 1 and a package frame support beam 2; the package frame upper crossbeam 1 and the package frame support beam 2 are arranged opposite to each other; this invention ensures the structural strength of the package beam through the cooperative use of the package frame upper crossbeam 1 and the package frame support beam 2.

[0035] Meanwhile, in this invention, the upper beam 1 of the parcel rack includes an upper horizontal plate 11 and a longitudinal plate 12, which are intersecting. The included angle between the upper horizontal plate 11 and the longitudinal plate 12 is greater than 90 degrees. The parcel rack support beam 2 includes a support plate body. The support plate body includes a supporting horizontal plate 22 and a supporting longitudinal plate 21. The supporting horizontal plate 22 and the supporting longitudinal plate 21 are intersecting. The included angle between the supporting horizontal plate 22 and the supporting longitudinal plate 21 is also greater than 90 degrees. This arrangement facilitates the overlap between the mounting plate 5 and the upper beam 1 of the parcel rack during subsequent use, and also facilitates the overlap between the parcel rack support beam 2 and the support plate 3.

[0036] Meanwhile, in this invention, the upper horizontal plate 11 and the supporting horizontal plate 22 are arranged at intervals relative to each other; the upper horizontal plate 11 and the supporting horizontal plate 22 are generally arranged parallel to each other, and the supporting vertical plate 21 and the longitudinal plate 12 are arranged at intervals relative to each other; the supporting vertical plate 21 and the longitudinal plate 12 are also arranged parallel to each other. This arrangement facilitates the subsequent formation of a U-shaped inner cavity.

[0037] In addition, in this invention, the horizontal beam 1 of the wrapping frame and the supporting beam 2 of the wrapping frame form a U-shaped inner cavity structure; based on the above design, it can be seen that the hollow beam structure inside the wrapping beam of this invention can reduce the weight of the wrapping beam while ensuring the structural strength of the wrapping beam.

[0038] Furthermore, the mounting frame mechanism in this invention includes a mounting plate 5 and a support plate 3; the mounting plate 5 and the support plate 3 are intersecting; one end of the mounting plate 5 is connected to the support plate 3, and the other end overlaps on the upper beam 1 of the parcel rack; one end of the support plate 3 is connected to the mounting plate 5, and the other end overlaps on the support beam 2 of the parcel rack; based on this arrangement, the parcel beam, the mounting plate 5, and the support plate 3 form a triangular structure, which helps to ensure the overall structural strength of the mounting structure.

[0039] Furthermore, in this invention, the mounting plate 5 includes a central arc-shaped plate 51; one end of the central arc-shaped plate 51 is connected to an upper mounting connecting plate 52; the other end is connected to a lower mounting connecting plate 53, and the mounting plate 5 overlaps on the upper beam 1 of the parcel rack through the upper mounting connecting plate 52; in this invention, the central arc-shaped plate 51 is equivalent to forming a groove in the central area of ​​the mounting plate 5, which plays a good role in avoiding obstacles and reinforcing.

[0040] In addition, in this invention, the central arc-shaped plate 51 is connected to the upper crossbeam 1 of the package frame through the upper mounting plate 52, and the central arc-shaped plate 51 is connected to the lower support plate 33 through the lower mounting plate 53, which ensures the stability of the connection between the mounting plate 5 and the support plate 3.

[0041] Furthermore, in this invention, the support plate 3 includes a support plate body, which includes a central support plate 31; one end of the central support plate 31 is connected to an upper support connecting plate 32, and the other end is connected to a lower support connecting plate 33; the support plate 3 is connected to the package rack support beam 2 via the upper support connecting plate 32; in this invention, the central support plate 31 is a support flat plate structure, the upper end of the central support plate 31 overlaps with the package rack support beam 2 via the upper support connecting plate 32, and the lower end of the central support plate 31 is connected to the lower mounting connecting plate 53 via the lower support connecting plate 33.

[0042] Based on the above design, it not only facilitates the connection between the mounting plate 5, the support plate 3 and the wrapping beam, but also facilitates the formation of a triangular support structure, which effectively ensures the overall structural strength of the mounting structure.

[0043] In addition, in this invention, a hook flange 54 can be provided at the end of the longitudinal plate 12 away from the upper horizontal plate 11. In subsequent use, it can be hooked into the groove formed by the middle arc plate 51. This means that in addition to the bolt connection, the mounting plate 5 and the upper beam 1 of the parcel rack also have a hook connection, which well ensures the stability of the connection between the upper beam 1 of the parcel rack and the mounting plate 5.

[0044] Based on this, when connecting the mounting plates later, the mounting plates can be hung on the hanging flange by the central arc plate, and then tightened with bolts. This connection method can not only ensure the accuracy of installation, but also reduce the labor intensity of operators and reduce the labor intensity of operators lifting and holding the plates.

[0045] Furthermore, in this invention, the lower mounting plate 53 in the mounting plate 5 and the lower support plate 33 in the support plate 3 are arranged longitudinally; this arrangement facilitates the installation and arrangement of the seat belt retractor 6. At the same time, in this invention, the mounting plate 5, the support plate 3, and the wrapping beam form a triangular cavity; this effectively ensures the strength of the installation structure and facilitates the stability of the retractor 6 when installed on the vehicle.

[0046] Furthermore, in this invention, the support plate body is provided with reinforcing edges 51 at its edge; reinforcing edges 51 are provided on opposite sides of the support plate body; this arrangement makes the support plate 3 form a U-shaped plate structure, which effectively ensures the structural strength of the support plate 3.

[0047] Furthermore, in this invention, the longitudinal plate 12 is inclined; the longitudinal plate 12 can provide better longitudinal support for the mounting plate 5, thereby better ensuring the stability of the mounting plate 5 arranged on the longitudinal plate 12; at the same time, in this invention, the bracket plate is attached to the inner wall of the upper beam 1 of the parcel rack through the support flange; this arrangement ensures the contact area between the bracket body and the inner wall of the upper beam 1 of the parcel rack, and better ensures the stability of the connection between the upper beam 1 of the parcel rack and the support beam 2 of the parcel rack.

[0048] Furthermore, the mounting plate 5 described in this invention is provided with a guide ring 7, which plays a good limiting role. The guide ring 7 is located above the seat belt retractor 6 and can limit the operation of the seat belt retractor.

[0049] Specifically, in this invention, the guide ring 7 includes a central U-shaped body 71; the two ends of the central U-shaped body 71 are respectively provided with overlapping connecting plates 72; the guide ring 7 is attached to the mounting plate 5 through the overlapping connecting plates 72; the present invention facilitates the connection of the guide ring 7 on the mounting plate 5 through the setting of the overlapping connecting plates 72; at the same time, the central U-shaped body 71 is mainly U-shaped in horizontal projection; the U-shape can limit the operation of the seat belt, which facilitates the subsequent winding operation of the seat belt.

[0050] Furthermore, in this invention, a package rack reinforcing plate 4 is provided on the inner wall of the crossbeam 1 of the package rack. By providing the package rack reinforcing plate 4, this invention effectively ensures the structural strength of the crossbeam 1 of the package rack.

[0051] In addition, in this invention, the guide ring 7, mounting plate 5, upper crossbeam 1 of the parcel rack, and parcel rack reinforcing plate 4 are connected by fastening bolts 8; each fastening bolt 8 is arranged to pass through the guide ring 7, mounting plate 5, upper crossbeam 1 of the parcel rack, and parcel rack reinforcing plate 4 in sequence; such an arrangement can realize the interconnection of the guide ring 7, mounting plate 5, upper crossbeam 1 of the parcel rack, and parcel rack reinforcing plate 4, while also reducing the use of fastening bolts 8.

[0052] A vehicle body assembly is provided with a mounting structure for the seat belt retractor; this facilitates the installation and connection of the seat belt retractor 6 on the vehicle body during subsequent use.

[0053] This invention discloses a mounting structure for a seatbelt retractor; the mounting structure for a seatbelt retractor disclosed in this invention can ensure the performance of the retractor mounting point 6 without encroaching on the luggage compartment volume, thus avoiding both increased cost and weight.

[0054] The technical solution of the present invention mainly includes a cavity structure formed by the crossbeam 1 of the parcel rack and the parcel rack support plate 3, and the local strength, stiffness and modality are improved by the reinforcing plate.

[0055] In addition, in this invention, the mounting plate 5, the support plate 3, and the wrapping beam work together to form a triangular support structure and are connected by bolts to ensure the rigidity of the mounting point.

[0056] The installation structure disclosed in this invention, without reducing the volume of the luggage compartment and avoiding the increase in cost and weight, forms a cavity structure by cooperating the crossbeam 1 on the parcel rack and the parcel rack support plate 3. The installation plate 5, the support plate 3 and the parcel beam cooperate to form a triangular support structure and are connected by bolts, thereby improving the local stiffness, modal stiffness and installation point stiffness.

[0057] Furthermore, it has a simple structure, is easy to implement, convenient to install, has a stable structure, and meets the performance requirements of the six mounting points of the retractor. Specific implementation examples:

[0059] The parcel rack's upper beam 1, parcel rack support plate 3, and parcel rack reinforcing plate 4 are welded together to form a closed rectangular cavity, which is effectively connected to the side wall, ensuring the strength and rigidity of the parcel rack area.

[0060] Mounting plate 5 and support plate 3 form a triangular support screw structure with the wrapping beam through fastening bolts 8 and nuts, providing a reliable mounting structure for guide ring 7.

[0061] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
