[0002] With the development of automobile design and manufacturing, while meeting basic functional requirements, vehicles have begun to develop towards more advanced interior structures. For example, components such as door interior panels and side interior panels that will directly affect people's visual senses in the car are gradually designed to be more technological and luxurious to promote passengers' intuitive experience of the vehicle, thereby promoting vehicle sales. However, the interior components of the vehicle usually need to be connected to the sheet metal structure of the vehicle as an integrated structure to achieve its stable setting. With the continuous updating of the shape of the interior components, it is difficult to maintain a flat connection between the interior surface and the sheet metal structure. The currently commonly used bolt or screw fixing structure is difficult to meet the stable connection between the interior components and the vehicle sheet metal, which affects the assembly effect and efficiency of the vehicle.

[0003] Therefore, how to achieve a stable and efficient connection between interior parts and vehicle sheet metal while the shape of interior parts is constantly updated is a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0004] The utility model provides a fixing bracket, an interior decoration assembly and a vehicle, so as to realize a stable and efficient connection between the interior decoration part and the vehicle sheet metal when the shape of the interior decoration part is constantly updated.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] In a first aspect, the utility model provides a fixing bracket, including a locking mechanism and a hooking mechanism, wherein the locking mechanism is used to fix and connect a vehicle sheet metal, and the hooking mechanism is used to hook with an interior trim panel;

[0007] The locking mechanism includes a connecting screw and a plug connector.

The hook mechanism includes a protrusion. The hook mechanism is inserted into the interior panel and is limited and clamped with the interior panel through the protrusion.

[0008] Optionally, the above-mentioned fixing bracket further includes a positioning mechanism, which extends out in the same direction as the plug connector and is arranged at intervals, and is used to prevent the fixing bracket from rotating when the connecting screws are tightened.

[0009] Optionally, in the above-mentioned fixing bracket, the positioning mechanism is a cross pin structure.

[0010] Optionally, in the above-mentioned fixing bracket, the hook mechanism is arranged in the area between the locking mechanism and the positioning mechanism.

[0011] Optionally, in the above-mentioned fixing bracket, the protrusion has the elastic ability to deform along the protruding direction, and grooves are formed on both sides of the area where the protrusion is arranged on the hook mechanism.

[0012] Optionally, in the above-mentioned fixing bracket, the slope of the side of the protrusion close to the plug connector is greater than the slope of the side of the protrusion away from the plug connector.

[0013] Optionally, in the above-mentioned fixing bracket, the plug connector includes a plurality of claws, which are evenly arranged along the circumference of the insertion hole on the locking mechanism and partially cover the insertion hole, and the connecting screws are arranged through the insertion hole and push the claws open to the surroundings.

[0025] With the development of vehicle diversity, the shape of vehicle interior parts is constantly updated to make users' intuitive experience of the vehicle have a sense of technology and luxury. However, this will inevitably lead to a more complex structure of interior parts. There are often scenarios where curved surface docking and locking with vehicle sheet metal are required. How to achieve a stable and efficient connection between interior parts and vehicle sheet metal and reduce the difficulty of assembling the corresponding structure while the shape of interior parts is constantly updated is of great significance to the smooth and efficient production of vehicles.

[0026] In order to make the technical personnel in this field better understand the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the utility model described in the claims.

[0027] See also Figure 1-5 The fixing bracket provided by the embodiment of the utility model mainly includes a locking mechanism 10 and a hook mechanism 20, wherein the locking mechanism 10 is used to fix and connect the vehicle sheet metal 40, and the hook mechanism 20 is used to hang with the interior panel 50. The fixing bracket is designed to adapt to vehicles of various models and sizes to have certain versatility and flexibility. Specifically, the locking mechanism 10 includes a connecting screw 110 and a plug connector 120. The plug connector 120 is used to be plugged with the mounting hole opened on the vehicle sheet metal 40, and the plug connector 120 is capable of being connected along its circumference. The floating deformation structure needs to be explained here that the plug connector 120 is capable of floating deformation along its circumference, specifically, the plug connector 120 can be expanded along its circumference to increase its outer diameter, and the design of the plug connector 120 needs to ensure that under normal conditions without being affected by external forces, its outer diameter is slightly smaller than the opening size of the mounting hole so that it can be smoothly inserted into the mounting hole. The structural design of the plug connector 120 allows the plug connector 120 to be adaptively adjusted in mounting holes of different sizes to ensure its tight and stable fit with the mounting hole, that is, the locking mechanism 10 and the vehicle sheet metal 40.

[0028] It should be noted that the circumferential floating deformation capability of the plug connector 120 allows the fixing bracket to adapt to mounting holes on vehicle sheet metal 40 of different sizes, thereby improving the versatility of the fixing bracket and reducing the need to design fixing brackets separately for different vehicle models.

[0029] On the basis of the above structure, the connecting screw 110 extends into the plug connector 120 from one side to apply force to the plug connector 120 to drive the plug connector 120 to expand. It should be noted that after the connecting screw 110 acts and expands, the outer diameter of the plug connector 120 will be larger than the opening size of the mounting hole, while maintaining its locking effect with the mounting hole. During the use of the above structure, the operator aligns and inserts the plug connector 120 on the fixing bracket with the corresponding mounting hole on the vehicle sheet metal 40, and then drives the connecting screw 110 into the plug connector 120 from the inside of the vehicle, so that the plug connector 120 expands and is locked and connected with the vehicle sheet metal 40.

[0030] It should be noted that the above structure designs the plug connector 120 as an expansion structure for stable locking, and the connection between the connecting screw 110 and the plug connector 120 may include but is not limited to threaded connection, wedge-shaped fixation, etc., which can support the inside of the plug connector 120 to drive the plug connector 120 to deform; at the same time, the design of driving the plug connector 120 to expand through the connecting screw 110 can achieve a fast and stable clamping effect, thereby improving the installation efficiency and ensuring the tight connection between the fixing bracket and the vehicle sheet metal 40.

[0031] It should be further explained that since the locking mechanism 10 is connected to the vehicle sheet metal 40, and the structure of the vehicle sheet metal 40 is usually only related to the vehicle model and usually changes less than the structure of the interior panel 50, the locking mechanism 10 can be designed to fit the inner side of the vehicle sheet metal 40, thereby improving the stability of the contact surface between the locking mechanism 10 and the vehicle sheet metal 40, avoiding slippage of the fixed bracket, and improving the connection effect.

[0032] The hook mechanism 20 is arranged on the side of the locking mechanism 10 facing away from the plug connector 120, so as to be connected with the interior trim panel 50 for hooking. Specifically, when the fixing bracket is in a connected state with the vehicle sheet metal 40, the hook mechanism 20 is in a state of extending toward the inner side of the vehicle body, so that the interior trim panel 50 can be slotted and the hook mechanism 20 can be inserted for hooking. At the same time, a protrusion 210 is also arranged on the hook mechanism 20. The width of the slot on the interior trim panel 50 is greater than the thickness of the hook mechanism 20, but the width of the protrusion 210 arranged on the hook mechanism 20 is greater than the width of the slot, so that after the hook mechanism 20 is engaged with the interior trim panel 50, the interior trim panel 50 is locked and limited by the protrusion 210; at the same time, considering that the structural dimensions of the interior trim panel 50 vary greatly, the protrusion 210 can be designed as a structure with adjustable protrusion height, so as to allow the operator to adjust it according to the thickness or shape of the interior trim panel 50 to ensure a firm connection.

[0033] In some embodiments of the utility model, in order to improve the connection effect of the fixing bracket, the fixing bracket also includes one or more auxiliary fixing members, such as reinforcing ribs or support bars, etc., to enhance the stability and bearing capacity of the overall structure. The auxiliary fixing members can be independently arranged and assembled components, or can be structural members integrally formed with the locking mechanism 10 and / or the hook mechanism 20.

[0034] The material of the fixing bracket can be metal, plastic, composite material or any other strong material suitable for vehicle use, and its surface can be treated with anti-corrosion, wear-resistant or aesthetic treatment, such as electroplating, spraying or anodizing.

[0035] Furthermore, since the operator's view will be blocked when the fixing bracket is connected to the vehicle sheet metal 40, one or more visual or tactile indicators, such as color markings, shape changes or sound signals, can be set on the fixing bracket to send a signal prompt when the operator aligns the locking mechanism 10 with the vehicle sheet metal 40, so as to improve the convenience of installation.

[0036] The fixing bracket provided by the embodiment of the utility model is provided with a locking mechanism 10 and a hook mechanism 20 to respectively connect with the vehicle sheet metal 40 and the interior trim panel 50 in the vehicle, thereby completing the assembly of the interior trim panel 50 on the vehicle, wherein the locking mechanism 10 is plugged into and matched with the mounting hole on the vehicle sheet metal 40 through the plug connector 120, and the plug connector 120 is expanded and locked with the vehicle sheet metal 40 by driving the connecting screw 110. Since the structural certainty of the vehicle sheet metal 40 is relatively high, the side of the locking mechanism 10 where the plug connector 120 is provided can be designed to fit the structure of the vehicle sheet metal 40, thereby improving the fitting state and locking effect of the fixing bracket and the vehicle sheet metal 40, and at the same time, the plug connector 120 of the expanded locking mechanism 10 can also match the mounting holes of a certain range of sizes. Thereby improving the versatility of the fixing bracket provided by the embodiment of the utility model; the hook mechanism 20 is arranged on the side of the locking mechanism 10 facing away from the plug connector 120, and the hook mechanism 20 is a design structure protruding toward the inner side of the vehicle so that it can be inserted into the interior of the interior panel 50. The groove on the interior panel 50 can be plugged into the hook mechanism 20, and at the same time, a protrusion 210 is provided on the hook mechanism 20 to lock the interior panel 50 when the interior panel 50 is inserted. The form of hanging connection can make the interior panel 50 easy to install and easy to disassemble, thereby improving the convenience of maintenance. The above-mentioned fixing bracket is easy to install, and the structural shape of the interior panel 50 is not affected by the update. Only a groove structure needs to be provided to achieve stable hanging with the hook mechanism 20, so that the fixing bracket is easy to install and has high versatility.

[0037] Furthermore, considering that there is usually a rotational movement during the process of the connecting screw 110 passing through the plug connector 120, there is a risk that the fixing bracket will move relative to the vehicle sheet metal 40, causing a misalignment problem between the interior panel 50 and the vehicle sheet metal 40 during installation, see Figure 2 and Figure 3 In some embodiments of the utility model, a positioning mechanism 30 is also provided on the fixing bracket. Specifically, the positioning mechanism 30 and the plug connector 120 extend in the same direction and are spaced apart. When connected to the vehicle sheet metal 40, the positioning mechanism 30 and the plug connector 120 are respectively inserted into two spaced apart holes on the vehicle sheet metal 40. The positioning mechanism 30 is used to prevent the fixing bracket from rotating when the connecting screw 110 is tightened, thereby ensuring the stability and reliability of the fixing bracket.

[0038] The positioning mechanism 30 cooperates with the corresponding positioning hole on the vehicle sheet metal 40 to form a second fixing point of the fixing bracket, thereby enhancing the stability of the fixing bracket.

[0039] On the basis of the above embodiment, the positioning mechanism 30 is preferably a cross pin structure, one end of which is fixedly connected to the body of the fixed bracket, and the other end is matched with the shape of the positioning hole on the vehicle sheet metal 40 and plugged in to ensure the accuracy and firmness of the positioning. The material of the cross pin is preferably high-strength steel or engineering plastic to provide sufficient strength and durability. At the same time, the cross pin can be designed to be detachable so that it can be selected whether to use it according to the positioning needs, and it is easy to install and maintain.

[0040] In the above structure, the purpose of the locking mechanism 10 and the positioning mechanism 30 is to enable the fixing bracket to have two force points with the vehicle sheet metal 40. Therefore, in some embodiments of the present invention, the hook mechanism 20 is preferably arranged in the area between the locking mechanism 10 and the positioning mechanism 30, so that the hook mechanism 20 can be effectively connected to the interior panel 50 without interfering with the functions of the locking mechanism 10 and the positioning mechanism 30. At the same time, the force exerted on the hook mechanism 20 by the interior panel 50 will be shared by the locking mechanism 10 and the positioning mechanism 30 on both sides without causing deviation. It should be noted that the setting surface of the hook mechanism 20 is preferably perpendicular to the plug connector 120 on the locking mechanism 10, so that the hook mechanism 20 of the same material can be extended as much as possible to stably hang the interior panel 50.

[0041] In addition, it should be noted that the fixing bracket may further include one or more shock-absorbing elements, which are arranged between the locking mechanism 10 and / or the hook mechanism 20 and the vehicle sheet metal 40 to absorb the vibration generated during the driving of the vehicle, reduce noise and extend the service life of the fixing bracket.

[0042] Furthermore, the hook mechanism 20 of the fixed bracket may include one or more auxiliary hooks, which can enhance the connection stability between the hook mechanism 20 and the interior panel 50, especially when the vehicle makes a sharp turn or travels on bumpy roads, thereby reducing the risk of connection failure between the fixed bracket and the interior panel 50.

[0043] Considering that the connection between the hook mechanism 20 and the interior trim panel 50 is a snap-on hook connection after extrusion, in some specific embodiments of the present invention, the protrusion 210 on the hook mechanism 20 is designed as an elastic structure, specifically, the protrusion 210 has the elastic ability to deform along the protruding direction. In a specific embodiment of the present invention, grooves are opened on both sides of the area where the protrusion 210 is set on the hook mechanism 20, and the protrusion 210 is arranged in a bridge shape on the hook mechanism 20, so that the protrusion 210 can be elastically deformed in the positive or reverse direction of the protruding direction when subjected to external force. In the process of connecting with the interior trim panel 50, the setting of the protrusion 210 can adapt to interior trim panels 50 of different thicknesses. The width of the groove on the interior trim panel 50 is smaller than the thickness of the protrusion 210 when it pops up, so that the interior trim panel 50 can be fixed in a limited position after being snapped with the hook mechanism 20, thereby enhancing the versatility and applicability of the fixing bracket.

[0044] In order to further optimize the above technical solution, in the fixing bracket provided in the embodiment of the utility model, the protrusion 210 is designed as a protrusion of a V-shaped structure, and the slope of the protrusion 210 on the side close to the plug connector 120 is greater than the slope on the side away from the plug connector 120. This design makes it easier for the protrusion 210 to enter the groove on the interior panel 50 when inserted, and can provide a better locking effect after installation. The side with a smaller slope helps to reduce the force required during installation, while the side with a larger slope can ensure that the protrusion 210 remains stable in the interior panel 50 to prevent loosening due to vibration during vehicle driving.

[0045] Further, see Figure 4In some embodiments of the present invention, the plug connector 120 includes a plurality of claws 1210, and an insertion hole for the connecting screw 110 to penetrate is opened on the plug connector 120. The claws 1210 are evenly arranged along the circumference of the insertion hole and partially cover the insertion hole. It should be noted here that the purpose of partially covering the insertion hole by the claws 1210 is to lift the claws 1210 after the connecting screw 110 penetrates the insertion hole, thereby driving the claws 1210 to expand and deform. The claws 1210 are evenly arranged along the circumference of the insertion hole, which can ensure that a force can be applied to each claw 1210 after the connecting screw 110 penetrates the insertion hole. At the same time, the force applied to each claw 1210 is the same, which can cause the plug connector 120 to produce uniform deformation in the circumferential direction. The above structural design allows the plug connector 120 to remain compact when not in use, reducing the occupied space, and when the connecting screw 110 is tightened, the claws 1210 can expand outward evenly to provide a better locking effect.

[0046] It should be noted that the outer periphery of the claw 1210 may also be provided with anti-slip texture or serrations to increase the friction between the claw 1210 and the vehicle sheet metal 40 , thereby improving the connection strength between the plug connector 120 and the vehicle sheet metal 40 .

[0047] In order to further optimize the above technical solution, it is preferred that two claws 1210 are provided on the plug connector 120, and each claw 1210 is provided with a guide groove 1220 for the connecting screw 110 to slide into. The design of the guide groove 1220 ensures the linear movement of the connecting screw 110 during the tightening process, reduces the deflection and jamming during installation, and improves the accuracy and reliability of installation. At the same time, the guide groove 1220 can also be designed as a self-lubricating structure, such as coating the inner wall of the groove body with a low-friction material to further reduce the friction during installation.

[0048] Furthermore, an embodiment of the utility model also provides an interior decoration assembly, which includes a door interior decoration and a side panel interior decoration, and in particular, a connecting groove is opened on the door interior decoration and / or the side panel interior decoration, and a fixing bracket provided by any of the above embodiments is plugged into the connecting groove and connected to the connecting groove through the protrusion 210 on the hook mechanism 20 and is connected to form an integrated structure by a snap-fitting connection, and the door interior decoration and the side panel interior decoration are fixedly connected to the vehicle sheet metal 40 through the locking mechanism 10 on the fixing bracket to form an integrated structure; at the same time, since the above-mentioned fixing bracket has the above-mentioned technical effects, the interior decoration assembly also has the above-mentioned technical effects, which will not be repeated herein.

[0049] Furthermore, some other embodiments of the utility model also provide a vehicle, which includes a vehicle sheet metal 40 and an interior assembly provided in the above embodiments, a mounting hole is opened on the vehicle sheet metal 40, and the interior assembly is fixedly connected to the mounting hole on the vehicle sheet metal 40 through a locking mechanism 10 on a fixed bracket connected thereto to form an integrated structure. Since the above interior assembly has the above technical effects, the vehicle also has the above technical effects, which will not be repeated herein.
