It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] Please also read Figures 1 to 8 Now, the connection assembly and the vehicle provided by the utility model are described. The connection assembly includes a mounting plate 1 and a rotating chuck 2. The side of the rotating chuck 2 is connected to a clamping arm 3 through an extension column 21. The extension column 21 is coaxially arranged with the rotating chuck 2. The clamping arm 3 extends along the radial direction of the rotating chuck 2. The clamping arm 3 sequentially penetrates the mounting plate 1, the plate to be mounted 6 and the vehicle body sheet metal 7. The clamping arm 3 can rotate circumferentially under the drive of the rotating chuck 2 to press against the inner side wall of the vehicle body sheet metal 7.

[0029] Compared with the prior art, the connection assembly provided in the present embodiment is that the clamping arm 3 on the rotating chuck 2 can pass through the installation disk 1, the plate to be installed 6 and the vehicle body sheet metal 7 in sequence, and the clamping arm 3 is driven to rotate a certain angle by rotating the rotating chuck 2, so that the clamping arm 3 can be pressed against the inner wall of the vehicle body sheet metal 7, so that the relative position of the plate to be installed 6 and the vehicle body sheet metal 7 is locked, thereby ensuring the reliable connection of the plate to be installed 6, avoiding the rust problem of the vehicle body sheet metal 7 or the plate to be installed 6 caused by the use of connecting parts such as bolts, and improving the reliability of the connection.

[0030] In this embodiment, the plate 6 to be installed can be installed on the side of the vehicle body sheet metal 7 by using the above-mentioned connection assembly. The plate 6 to be installed can be a plate-shaped component to be installed on the vehicle body sheet metal 7, or a plate body with a certain thickness on the decorative component. The plate 6 to be installed is installed on the vehicle body sheet metal 7 by using the connection assembly, thereby achieving the effect of installing the decorative component or the plate-shaped component on the vehicle body sheet metal 7. The shape and size of the above-mentioned decorative component and the plate-shaped component are not limited. As long as the decorative component has a plate 6 to be installed that can be clamped between the mounting plate 1 and the vehicle body sheet metal 7, the above-mentioned connection assembly can be used for installation and connection.

[0031] After the existing screws or bolts and other connectors connect the decorative components or plate-like components to the side of the body sheet metal 7, the cutting effect of the screws or bolts and other connectors and the body sheet metal 7 during the threaded screwing process easily forms rust at the threaded contact parts between the screws or bolts and other connectors and the body sheet metal 7. Compared with the above method, after the plate 6 to be installed is connected to the side of the body sheet metal 7 by using the connecting assembly, the end surface of the clamping arm 3 and the inner side wall of the body sheet metal 7 form a pressing effect. This connection method does not have a cutting effect, so the connecting assembly can effectively prevent the body sheet metal 7 and the plate 6 to be installed from rusting.

[0032] For ease of description, the exposed side of the body sheet metal 7, that is, the side for installing the decorative component, is defined as the outer side, and the other side of the body sheet metal 7 is defined as the inner side. The side walls of the mounting plate 1, the rotating chuck 2, and the plate 6 to be mounted close to the body sheet metal 7 are defined as the inner side walls, and the side walls of the mounting plate 1, the rotating chuck 2, and the plate 6 to be mounted away from the body sheet metal 7 are defined as the outer side walls.

[0033] In this embodiment, the clamping arm 3 extends a certain length along the radial direction of the rotating chuck 2. In order to enable the clamping arm 3 to smoothly pass through the mounting plate 1, the plate to be mounted 6 and the body sheet metal 7, a first hole 14 is pre-opened on the mounting plate 1, a second hole 61 is pre-opened on the plate to be mounted 6, and a third hole 71 is pre-opened on the body sheet metal 7. The hole shape of the first hole 14 is consistent with the cross section of the clamping arm 3, and the hole shape of the second hole 61 can be consistent with the cross section of the clamping arm 3, or an inconsistent hole shape can be adopted, as long as the passing requirement of the clamping arm 3 is met. The hole shape of the third hole 71 can be consistent with the cross section of the clamping arm 3, or an inconsistent hole shape can be adopted, as long as the passing requirement of the clamping arm 3 is met. Specifically, the hole shapes of the first hole 14 and the second hole 61 are consistent with those of the clamping arm 3, and the third hole 71 is in the form of a rectangular hole, which is convenient for processing operations and the installation of decorative components or plate-like components.

[0034] During initial installation, the length direction of the clamping arm 3 is consistent with the long axis direction of the first hole 14, the second hole 61 and the third hole 71, ensuring smooth insertion of the clamping arm 3. When the clamping arm 3 rotates with the rotating chuck 2, the clamping arm 3 rotates by a certain angle, and its long axis direction is cross-set with the long axis direction of the third hole 71, that is, the clamping arm 3 and the third hole 71 are relatively misaligned to prevent the clamping arm 3 from slipping out of the third hole 71. The side wall of the clamping arm 3 adjacent to the rotating chuck 2 is limited by the inner wall of the vehicle body sheet metal 7, ensuring a reliable installation effect.

[0035] At this time, the clamping arm 3 is connected to the inner wall of the rotating chuck 2 through the extension column 21. The extension column 21 creates a gap between the clamping arm 3 and the rotating chuck 2. The gap is used to accommodate the mounting disk 1, the plate to be mounted 6 and the vehicle body sheet metal 7. The mounting disk 1 and the plate to be mounted 6 are clamped on the outside of the vehicle body sheet metal 7 by the rotating chuck 2 to achieve installation and fixation of the plate to be mounted 6.

[0036] It should be noted that, in order to facilitate the circumferential rotation of the rotating chuck 2, the rotating chuck 2 is selected to be circular, and the shape of the mounting plate 1 is not limited, and can be circular, trapezoidal, rectangular, etc. Specifically, a circular mounting plate 1 can be selected to coordinate with the shape of the rotating chuck 2 to facilitate subsequent positioning and installation.

[0037] The connection assembly is very convenient to operate during installation, and its locking force is higher than that of traditional plastic buckles, thereby ensuring the effective installation of decorative components or plate-like components and improving the reliability of the connection.

[0038] In some possible implementations, the above-mentioned characteristic clamping arm 3 is adopted as follows Figures 3 to 6 See the structure shown. Figures 3 to 6 Two ends of the clamping arm 3 are respectively provided with extension ears 31 , and the two extension ears 31 are respectively located on both sides of the clamping arm 3 and extend along the tangential direction of the rotating chuck 2 .

[0039] In this embodiment, by providing the extension ears 31 on both sides of the clamping arm 3, the abutment between the clamping arm 3 and the inner wall of the vehicle body sheet metal 7 is enhanced, the clamping arm 3 is prevented from detaching from the outer side of the vehicle body sheet metal 7, and the reliability of the structural installation is improved.

[0040] In some possible implementations, the characteristic extension ear 31 is as follows: Figures 5 and 6 See the structure shown. Figures 5 and 6 The side of the extension ear 31 adjacent to the rotating chuck 2 has an inclined guide surface 32. From the inner end of the extension ear 31 to the outer end of the extension ear 31, the guide surface 32 gradually extends obliquely toward the side away from the rotating chuck 2. The guide surface 32 is used to guide the end surface of the clamping arm 3 to press against the inner wall of the vehicle body sheet metal 7.

[0041] In this embodiment, the guide surface 32 is provided on the extension ear 31 so that the rotating chuck 2 is guided to move axially during the rotation process. In the initial stage of installation, the length of the clamping arm 3 extending into the inner side of the vehicle body sheet metal 7 is not enough, and the outer end of the extension ear 31 contacts the edge of the long side of the third hole 71 first. Under the guidance of the guide surface 32, the clamping arm 3 can be axially moved into the inner side of the vehicle body sheet metal 7 until the end face of the clamping arm 3 can be effectively pressed against the inner side wall of the vehicle body sheet metal 7, so as to effectively press the middle plate 6 to be installed, and realize reliable fixation of the plate 6 to be installed.

[0042] In some embodiments, the above-mentioned characteristic clamping arm 3 can be used as follows Figures 5 and 6 See the structure shown. Figures 5 and 6 A weight-reducing cavity 33 is provided on the end surface of the clamping arm 3 facing away from the rotating chuck 2 , and a plurality of reinforcing ribs 34 are provided in the weight-reducing cavity 33 . The reinforcing ribs 34 extend along the tangential direction of the rotating chuck 2 .

[0043] In this embodiment, a weight-reducing cavity 33 is provided on the side wall of the clamping arm 3 away from the rotating chuck 2. Under the premise of ensuring the structural strength of the clamping arm 3, the setting of the weight-reducing cavity 33 can effectively reduce the material consumption of the clamping arm 3, which helps to reduce costs.

[0044] On this basis, the structure of the clamping arm 3 is strengthened by arranging a reinforcing rib plate 34 inside the weight-reducing cavity 33, so that an effective contact force is formed between the clamping arm 3 and the body sheet metal 7, meeting the fixing requirements of the mounting plate 6. This arrangement facilitates the lightweight design of the vehicle body and also helps to reduce material costs.

[0045] Specifically, the reinforcing rib plate 34 extends radially along the rotating chuck 2 , dividing the weight-reducing cavity 33 into a plurality of rectangular spaces, thereby ensuring the structural strength of the clamping arm 3 at different positions and improving the rationality of the structural arrangement.

[0046] In some possible implementations, the above-mentioned characteristic rotating chuck 2 is used as follows Figures 3 to 6 See the structure shown. Figures 3 to 6 A sealing gasket 4 is provided on the inner side of the rotating chuck 2 . The sealing gasket 4 is sleeved on the outer periphery of the extension column 21 . The sealing gasket 4 can be pressed against the outer side wall of the mounting plate 1 .

[0047] In this embodiment, a sealing gasket 4 is provided on the rotating chuck 2 to achieve a sealed connection between the rotating chuck 2 and the mounting disk 1, thereby preventing water vapor outside the rotating chuck 2 from entering the inner side of the mounting disk 1, avoiding the rust problem of the vehicle body sheet metal 7 or the plate to be installed 6, and improving the structural sealing performance.

[0048] Specifically, the rotary chuck 2 is provided with a through hole 24, the sealing gasket 4 is formed by injection molding, and the sealing gasket 4 is provided with a fixing portion 41 extending into the through hole 24. The above structure can ensure that the sealing gasket 4 is reliably connected to the inner side of the rotary chuck 2, facilitating subsequent assembly operations.

[0049] In some embodiments, the above-mentioned characteristic rotating chuck 2 can be used as follows Figure 1 , Figure 2 , Figures 5 and 6 See the structure shown. Figure 1 , Figure 2 , Figures 5 and 6 A screwing head 22 is disposed on the outer side of the rotary chuck 2, and a radially extending tool hole 23 is disposed on the outer end surface of the screwing head 22, and the tool hole 23 is used to match with the tool head.

[0050] In this embodiment, when the rotary chuck 2 is driven to rotate, it can be achieved by applying force to the screwing head 22. The screwing head 22 can be a strip structure extending radially along the rotary chuck 2, which is convenient for direct screwing operation by hand.

[0051] When the screwing head 22 is small in size and difficult to be directly operated by hand, a tool hole 23 can be provided on the outer end surface of the knob head, and the tool head of the tool is inserted into the tool hole 23 to drive the screwing head 22, thereby driving the rotary chuck 2 to rotate circumferentially. The above tool can be a flat-blade screwdriver, and the flat-blade head at the front end of the flat-blade screwdriver can be inserted into the tool hole 23, which improves the convenience of operation and helps to improve assembly efficiency.

[0052] In some possible implementations, the above-mentioned characteristic installation disk 1 is used as follows Figures 5 and 6 See the structure shown. Figures 5 and 6 A clamping seat 5 for limiting the axial position of the rotating chuck 2 is provided on the outer side of the mounting disk 1. The outer end of the clamping seat 5 has a clamping platform 51 protruding toward the axial side of the mounting disk 1. The clamping platform 51 can be clamped on the outer side wall of the rotating chuck 2 to limit the axial position of the rotating chuck 2 and the mounting disk 1.

[0053] In this embodiment, a clamping seat 5 is further provided on the outside of the mounting plate 1. The clamping seat 5 uses the clamping platform 51 to limit the outer wall of the rotating chuck 2, so as to realize the axial pre-installation between the rotating chuck 2 and the mounting plate 1, and prevent the clamping arm 3 from being separated from the vehicle body sheet metal 7 outward. The clamping seat 5 extends to the outside of the mounting plate 1, and has a tendency to tilt toward the central axis of the mounting plate 1, so as to be pressed against the peripheral wall of the rotating chuck 2, and ensure that the clamping platform 51 limits the outer wall of the rotating chuck 2.

[0054] At the same time, the clamping platform 51 can be integrally formed on the clamping seat 5, and the clamping platform 51 is located on the side of the clamping seat 5 close to the axis of the mounting plate 1. This setting makes the clamping platform 51 form an effect of pressing against the outer wall of the rotating chuck 2. During installation, the rotating chuck 2 is first installed on the outer side of the mounting plate 1, and then the rotating chuck 2 and the mounting plate 1 are installed as a whole on the plate to be installed 6, so that the clamping arm 3 passes through the plate to be installed 6 and the body sheet metal 7, and then the rotating chuck 2 is rotated to effectively lock the plate to be installed 6. The above method can effectively reduce the difficulty of assembly, improve assembly efficiency, and facilitate the accuracy of installation.

[0055] In some possible implementations, the above-mentioned characteristic installation disk 1 is used as follows Figures 7 and 8 See the structure shown. Figures 7 and 8 A plurality of circumferentially extending positioning arc plates 11 are provided on the outer side of the mounting plate 1 , and the plurality of positioning arc plates 11 enclose a space for accommodating the rotating chuck 2 .

[0056] In this embodiment, a plurality of limiting arc plates are provided on the side of the mounting disk 1 at circumferential intervals along the mounting disk 1, which can form a space for accommodating the rotating chuck 2. When installing the rotating chuck 2, it is convenient to perform preliminary positioning of the rotating chuck 2 and the mounting disk 1. Combined with the setting of the clamping seat 5, the rotating chuck 2 can be conveniently installed on the side of the mounting disk 1, thereby improving the convenience of operation.

[0057] After that, the rotating chuck 2 is rotated to move toward the side close to the body sheet metal 7 under the guidance of the guide surface 32 until the sealing gasket 4 is pressed against the outer wall of the mounting plate 1. At this time, the end surface of the clamping arm 3 can also fit tightly with the inner wall of the body sheet metal 7 to ensure a reliable connection effect. Specifically, the mounting plate 1 and the rotating chuck 2 are both plastic components, which can effectively prevent the body sheet metal 7 and the plate 6 to be installed from rusting.

[0058] In some embodiments, the above-mentioned characteristic mounting plate 1 can be used as follows Figures 7 and 8 See the structure shown. Figures 7 and 8 The outer wall of the mounting plate 1 is provided with a rotation direction mark 12 located at the outer periphery of the positioning arc plate 11 , and two rotation direction marks 12 are provided, and the two rotation direction marks 12 are symmetrically arranged on both sides of the axis of the mounting plate 1 .

[0059] In this embodiment, by providing a rotation direction mark 12 on the mounting plate 1, the operator can be instructed to rotate in the corresponding direction, thereby ensuring the guiding function of the guide surface 32. This facilitates identification by the operator and improves the convenience of operation.

[0060] On the basis of the above structure, an avoidance cavity 13 is further provided on the inner wall of the mounting plate 1. The avoidance cavity 13 is located on the outer periphery of the first hole 14, which can reduce the contact area between the mounting plate 1 and the plate 6 to be mounted, thereby helping to ensure the tightness of the fit and ensuring effective fastening of the plate 6 to be mounted.

[0061] Directions:

[0062] The rotating chuck 2 is mounted on the mounting plate 1, and the clamping arm 3 passes through the first hole 14 of the mounting plate 1. At this time, the rotating chuck 2 can be stably located outside the mounting plate 1 under the action of the clamping seat 5. Afterwards, the plate 6 to be mounted is attached to the corresponding part of the body sheet metal 7, so that the long axes of the second hole 61 and the third hole 71 are aligned and coincident, meeting the passing requirement of the clamping arm 3.

[0063] Then, the mounting plate 1 and the rotating chuck 2 are integrally mounted to the outside of the plate 6 to be mounted, and the clamping arm 3 passes through the second hole 61 and the third hole 71 and extends into the inside of the vehicle body sheet metal 7. The screwing head 22 on the outside of the rotating chuck 2 is rotated, and under the action of the guide surface 32, the rotating chuck 2 and the clamping arm 3 are synchronously moved a small amount to the inside of the vehicle body sheet metal 7. When the rotating chuck 2 is rotated to an angle of 90°, the clamping arm 3 is perpendicular to the long axis of the third hole 71, and the plate 6 to be mounted is stably mounted to the side of the vehicle body sheet metal 7, completing the mounting operation.

[0064] Based on the same inventive concept, the embodiment of the present application further provides a vehicle, the vehicle comprising a connection assembly. The vehicle can install the decorative component or plate-like component on the vehicle body sheet metal 7 through the connection assembly, thereby improving the connection strength between the decorative component or plate-like component and the vehicle body sheet metal 7, avoiding the corrosion problem of the vehicle body sheet metal 7 and the plate to be installed 6, and ensuring a good connection effect.

[0065] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
