Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0042] Sealing strips on the vehicle body, such as door sealing strips and sealing strip joints, are usually provided with connection structures. Sheet metal holes matching the connection structures are formed on the vehicle body sheet metal. Through the connection between the connection structure and the sheet metal hole, the assembly of the sealing strip on the vehicle body is realized.

[0043] However, the connection between the connection structure in the related art and the vehicle body sheet metal is inconvenient, resulting in difficult assembly of the sealing strip on the vehicle body.

[0044] Based on this, this embodiment provides a vehicle snap device, a vehicle sealing structure and a vehicle. By providing a mounting seat and an engaging structure, the engaging structure includes at least two engaging portions provided on one side of the mounting seat, and one ends of the engaging portions are all connected to the mounting seat, and the other ends of the engaging portions all extend away from the mounting seat and are connected together, and a snap deformation space is commonly enclosed between all the engaging portions. Such a setting enables the engaging portions to move toward or away from the snap deformation space to undergo elastic deformation. Thus, through the elastic snap fit between the engaging structure and the sheet metal hole, the seal connected to the mounting seat can be assembled on the vehicle body, which reduces the assembly difficulty of the seal on the vehicle body sheet metal to a certain extent, making the assembly of the seal on the vehicle body more convenient.

[0045] Next, the vehicle snap device, the vehicle sealing structure and the vehicle provided in this embodiment will be described in detail through specific embodiments with reference to the accompanying drawings:

[0046] Refer to Figures 1 to 6 As shown, this embodiment provides a vehicle snap device 10, which is used to connect a seal 20 to a vehicle body sheet metal 30.

[0047] Among them, the seal 20 can be, for example, a door seal, a seal corner joint, etc.

[0048] Specifically, referring to Figures 1 to 3 and Figure 5 As shown, the vehicle buckle device 10 includes a mounting seat 1 and an engaging structure. The mounting seat 1 is used to connect with the seal 20. The engaging structure includes at least two engaging portions 2. At least two engaging portions 2 are all arranged on one side of the mounting seat 1, and one end of each engaging portion 2 is connected to the mounting seat 1. The other end of each engaging portion 2 extends in a direction away from the mounting seat 1, and the other ends of all the engaging portions 2 are connected to each other, so that a deformation space for engaging is formed jointly among all the engaging portions 2, enabling the engaging structure to be elastically engaged in the sheet metal hole of the vehicle body sheet metal 30 or disengaged from the sheet metal hole.

[0049] During specific use, the mounting seat 1 and the seal 20 can be pre-connected together, for example, so that the seal 20 and the vehicle buckle device 10 of this embodiment are connected to form an integral structure. In this way, after connecting the engaging structure to the sheet metal hole of the vehicle body sheet metal 30, the connection between the seal 20 and the vehicle body sheet metal 30 is achieved, and the assembly is relatively convenient.

[0050] In some implementation manners, the mounting seat 1 is, for example, injection-molded with the seal 20 in the form of an insert, with good integrity, high structural strength and stability.

[0051] In other implementation manners, the mounting seat and the seal are connected together in a hard-fitting manner. Exemplarily, the seal can include a skeleton, and a mounting hole is provided on the skeleton. The mounting seat can be a mounting post that matches the mounting hole. The mounting post passes through the mounting hole and is in interference fit with the mounting hole to achieve the connection between the buckle device and the seal.

[0052] By making the engaging structure include at least two engaging portions 2, one end of each engaging portion 2 is connected to the mounting seat 1, the other end of each engaging portion 2 extends in a direction away from the mounting seat 1, and the other ends of all the engaging portions 2 are connected to each other, that is, the ends of each engaging portion 2 facing away from the mounting seat 1 are connected to each other. In this way, the engaging structure is located on the side of the mounting seat 1 facing away from the seal 20, facilitating the connection between the engaging structure and the sheet metal hole on the vehicle body sheet metal 30, realizing the assembly between the seal 20 and the vehicle body sheet metal 30, and thus making the assembly between the seal 20 and the vehicle body sheet metal 30 relatively convenient.

[0053] Meanwhile, all the engaging parts 2 jointly enclose an engaging deformation space. The engaging structure can move toward or away from the engaging deformation space to undergo elastic deformation, and it has good elastic deformation performance. Thus, the engaging structure can be elastically engaged in the sheet metal hole to assemble the seal 20 on the vehicle body sheet metal 30, or the engaging structure can be disengaged from the sheet metal hole to disassemble the seal 20 from the vehicle body sheet metal 30. As a result, the connection between the seal 20 and the vehicle body sheet metal 30 is more convenient and facilitates assembly.

[0054] Moreover, since one end of each engaging part 2 is connected to the mounting seat 1 and the other ends of each engaging part 2 are connected to each other, compared with the prior art where one end of the engaging part 2 is suspended, the structural strength of each engaging part 2 is improved, and the overall structural strength and stability of the engaging structure are greater. This improves the connection stability between the engaging structure elastically engaged in the sheet metal hole and the sheet metal hole, and further makes the assembly stability of the seal 20 on the vehicle body better, enhancing the sealing effect of the seal 20.

[0055] Furthermore, by connecting one end of each engaging part 2 to the mounting seat 1 and connecting the other ends of each engaging part 2 to each other, all the engaging parts 2 jointly enclose an engaging deformation space. In this way, on the basis of the elastic deformation of the engaging part 2, its structural strength is also relatively high, thus to a certain extent avoiding the phenomenon that the engaging structure is damaged during the disassembly process of the vehicle buckle device 10 of this embodiment. After the engaging structure is disassembled from the vehicle body sheet metal 30, it can be reset, which is convenient for subsequent reuse, such as reassembling the seal 20 onto the vehicle body after maintenance. It has a long service life, and to a certain extent, extends the service life of the seal 20, helping to reduce the vehicle use cost of users.

[0056] Exemplarily, as shown in Figure 1 and Figure 3 the engaging structure includes two engaging parts 2. The two engaging parts 2 are arranged at intervals along the circumferential direction of the mounting seat 1 and are connected to one side of the mounting seat 1.

[0057] The snap device 10 for a vehicle provided in this embodiment, by providing a mounting seat 1 and a snap structure, makes the snap structure include at least two snap portions 2 provided on one side of the mounting seat 1, and makes one end of each snap portion 2 connected to the mounting seat 1, and the other end of each snap portion 2 extends in a direction away from the mounting seat 1 and is connected together, and a snap deformation space is commonly enclosed among all the snap portions 2. Such a setting enables the snap portions 2 to move in a direction close to or away from the snap deformation space and undergo elastic deformation, with better elastic deformation ability, realizing elastic snap connection of the snap structure in the sheet metal hole of the vehicle body sheet metal 30 or disengaging from the sheet metal hole, and the installation and disassembly are relatively convenient. Since the snap structure is connected to the mounting seat 1, and the mounting seat 1 is used to connect to the seal 20, the connection between the snap device 10 for a vehicle provided in this embodiment and the vehicle body sheet metal 30 is relatively convenient. During connection, through the elastic snap of the snap structure and the sheet metal hole, the seal 20 connected to the mounting seat 1 can be assembled on the vehicle body, reducing the assembly difficulty of the seal 20 on the vehicle body sheet metal 30 to a certain extent, so that the assembly of the seal 20 on the vehicle body is relatively convenient and easy for assembly.

[0058] Meanwhile, since one end of each snap portion 2 is connected to the mounting seat 1 and the other ends of each snap portion 2 are connected to each other, such a setting makes the structural strength of the snap structure relatively high, improving the connection stability between the snap structure and the sheet metal hole, thereby improving the assembly stability of the seal 20 on the vehicle body, and further improving the sealing effect of the seal 20. And to a certain extent, it also avoids the phenomenon that the snap portions 2 are damaged during disassembly, prolonging the service life, so that the seal strip connected to the snap device 10 of this embodiment can be reused after being disassembled. For example, when maintaining and servicing the vehicle, the disassembled seal 20 can be reassembled on the vehicle body sheet metal 30, reducing the use cost to a certain extent.

[0059] Refer to Figure 1 、 Figure 3 and Figure 5 As shown, in some embodiments, each snap portion 2 includes a snap section 21 and an insertion section 22. One end of each snap section 21 is connected to the mounting seat 1, each insertion section 22 is respectively connected to the other end of the corresponding snap section 21, and the ends of all the insertion sections 22 away from the snap sections 21 are connected together, with a simple structure and easy to manufacture.

[0060] Wherein, in the direction from the snap section 21 to the insertion section 22, at least part of each snap section 21 is used to penetrate through the sheet metal hole, and at least part of the snap deformation space is commonly enclosed among all the snap sections 21 to abut and cooperate with the sheet metal hole.

[0061] The snap-fit deformation space provides at least space for the elastic deformation of each snap-fit segment 21. All the snap-fit segments 21 can move towards or away from the snap-fit deformation space, undergo elastic deformation, and elastically snap into or disengage from the sheet metal hole, making the connection between the snap-fit structure and the sheet metal hole convenient and stable. Thus, the connection between the seal 20 and the vehicle body sheet metal 30 is relatively convenient and stable, facilitating assembly.

[0062] When the snap-fit structure is inserted into the sheet metal hole, on the side of each snap-fit segment 21 facing away from the snap-fit deformation space, it abuts and cooperates with the inner wall of the sheet metal hole under the action of elastic force, elastically snapping the snap-fit structure into the sheet metal hole to achieve snap-fit connection.

[0063] During specific use, insert the insertion segment 22 into the sheet metal hole, and then move the vehicle buckle device 10 of this embodiment towards the vehicle body sheet metal 30 along the direction from the snap-fit segment 21 to the insertion segment 22 until all the snap-fit segments 21 are elastically snapped into the sheet metal hole, thus achieving the connection between the snap-fit structure and the sheet metal hole, which is convenient and stable.

[0064] Reference Figure 1 、 Figure 3 and Figure 5 As shown, in some embodiments, along the direction from the snap-fit segment 21 to the insertion segment 22, at least part of the side of the insertion segment 22 close to the snap-fit deformation space is inclined towards the snap-fit deformation space. This setting enables all the insertion segments 22 to jointly enclose the snap-fit deformation space. It not only allows the insertion segments 22 to undergo elastic deformation, facilitating assembly, but also increases the area of the snap-fit deformation space, enhancing the elastic deformation performance of the snap-fit structure and making the connection between the snap-fit structure and the sheet metal hole more firm.

[0065] Reference Figure 1 、 Figure 3 and Figure 5 As shown, along the direction from the snap-fit segment 21 to the insertion segment 22, at least part of the side of the insertion segment 22 facing away from the snap-fit deformation space is inclined towards the snap-fit deformation space. With this setting, along the direction from the snap-fit segment 21 to the insertion segment 22, the circumferential dimension formed by the sides of all the insertion segments 22 facing away from the snap-fit deformation space gradually decreases. In other words, along the direction from the insertion segment 22 to the snap-fit segment 21, that is, the insertion direction when the snap-fit structure elastically snaps into the sheet metal hole, the outer wall dimension of the circumference formed by all the insertion segments 22 increases successively, having an insertion guiding effect, facilitating all the insertion segments 22 to be inserted into the sheet metal hole and enabling all the snap-fit segments 21 to be elastically snapped into the sheet metal hole, making the assembly convenient. At the same time, on the basis of ensuring the structural strength, it also improves the elastic deformation performance of the snap-fit part 2 to a certain extent.

[0066] In some embodiments, the engaging section 21 and the corresponding inserting section 22 are integrally formed, which has good integrity and high structural strength. This further avoids the phenomenon that the engaging portion 2 is damaged during disassembly, extends the service life, enables the vehicle buckle device 10 of this embodiment to be reused, and reduces the use cost.

[0067] Reference Figure 1 、 Figure 3 and Figure 5 As shown, in some embodiments, a first limiting portion 3 is provided on a side of at least one engaging portion 2 facing away from the engaging deformation space, and the first limiting portion 3 is used to limit the elastic engaging connection between the engaging portion 2 and the sheet metal hole.

[0068] Specifically, when the engaging portion 2 is inserted into the sheet metal hole, the first limiting portion 3 and the mounting seat 1 are located on two sides of the vehicle body sheet metal 30, so that the area of the engaging portion 2 between the first limiting portion 3 and the mounting seat 1 can be elastically engaged in the sheet metal hole more firmly, to a certain extent avoiding the phenomenon that the engaging portion 2 shakes in the direction from the mounting seat 1 to the engaging portion 2, and thus avoiding the accidental detachment of the engaging portion 2 from the sheet metal hole, improving the connection stability, and further improving the assembly stability of the seal 20 on the vehicle body.

[0069] Reference Figure 1 、 Figure 3 and Figure 5 As shown, in some embodiments, a first limiting portion 3 is provided on each engaging portion 2, that is to say, a first limiting portion 3 is provided on a side of all engaging portions 2 facing away from the engaging deformation space, improving the limiting effect on the elastic engaging connection between the engaging portion 2 and the sheet metal hole, and making the connection between the engaging portion 2 and the sheet metal hole more firm.

[0070] In some embodiments, as shown in reference Figure 3 and Figure 5 the first limiting portion 3 includes a limiting protrusion, which has a simple structure, is easy to manufacture, and has a good limiting effect.

[0071] In specific implementation, a limiting inclined surface 31 is provided on a side of the limiting protrusion facing the mounting seat 1, and in the direction from the mounting seat 1 to the engaging portion 2, that is, in the pulling-out direction when the engaging structure disengages from the sheet metal hole, the limiting inclined surface 31 is inclined in a direction away from the engaging deformation space, that is to say, the limiting inclined surface 31 is inclined outwards, so as to further avoid the phenomenon that the engaging portion 2 accidentally detaches from the sheet metal hole, improve the connection stability, and further improve the assembly stability of the seal 20 on the vehicle body.

[0072] Meanwhile, by arranging the limiting inclined surface 31 to incline away from the clamping deformation space in the direction from the mounting seat 1 to the clamping portion 2, when in the direction from the clamping portion 2 to the mounting seat 1, that is, in the insertion direction when the clamping portion 2 is engaged with the sheet metal hole, the limiting inclined surface 31 inclines inwards, so as to guide the elastic clamping between the clamping portion 2 and the sheet metal hole, facilitating the connection.

[0073] In some embodiments, referring to Figure 3 and Figure 5 as shown, each clamping portion 2 includes a clamping section 21 and an insertion section 22. One end of each clamping section 21 is connected to the mounting seat 1. At least part of the clamping section 21 is used to pass through the sheet metal hole. All the clamping sections 21 together enclose at least part of the clamping deformation space to abut and cooperate with the sheet metal hole. One end of at least one insertion section 22 is connected to the corresponding clamping section 21 through a transition section 7. In the direction from the clamping section 21 to the insertion section 22, the transition section 7 extends away from the clamping deformation space, and at least part of the transition section 7 is formed as a first limiting portion 3.

[0074] Connecting the insertion section 22 and the clamping section 21 through the transition section 7, to a certain extent, avoids the phenomenon that the joint between the insertion section 22 and the clamping section 21 breaks due to stress concentration, thus further improving the structural strength of the clamping portion 2, avoiding the damage during disassembly, prolonging the service life, and facilitating repeated use.

[0075] Moreover, in the direction from the clamping section 21 to the insertion section 22, that is, in the pulling-out direction when the clamping structure disengages from the sheet metal hole, the transition section 7 extends away from the clamping deformation space. That is to say, in the direction where the clamping section 21 disengages from the sheet metal hole, the transition section 7 inclines outwards, further avoiding the accidental disengagement of the clamping section 21 from the sheet metal hole, improving the connection stability of the elastic clamping between the clamping section 21 and the sheet metal hole, and further improving the assembly stability of the seal 20 on the vehicle body.

[0076] In some implementation manners, the joint between the transition section 7 and the insertion section 22 can be smoothly transitioned, for example, which is convenient for assembly, and at the same time can avoid the phenomenon of stress concentration, further improving the structural strength of the clamping portion 2.

[0077] In other implementation manners, the joint between the transition section 7 and the clamping section 21 can be smoothly transitioned, for example, which is convenient for assembly, and at the same time can avoid the phenomenon of stress concentration, further improving the structural strength of the clamping portion 2.

[0078] Certainly, both the joint between the transition section 7 and the insertion section 22 and the joint between the transition section 7 and the clamping section 21 can be smoothly transitioned.

[0079] In some implementations, each insertion section 22 is connected to the corresponding engagement section 21 through a transition section 7, further avoiding the accidental detachment of the engagement structure from the sheet metal hole and making the connection between the engagement structure and the sheet metal hole more stable.

[0080] In some embodiments, the transition section 7, the engagement section 21, and the insertion section 22 are integrally formed, with good integrity and relatively high structural strength, further preventing the engagement portion 2 from being damaged during disassembly and extending the service life of the engagement portion 2 and the vehicle buckle device 10.

[0081] Reference Figure 1 、 Figure 2 and Figure 6 As shown in

[0082] In some embodiments, the engagement structure further includes a support member 4. At least a part of the support member 4 is located within the engagement deformation space. One end of the support member 4 is connected to the mounting seat 1, and the other end of the support member 4 is connected to the ends of all the engagement portions 2 that are away from the mounting seat 1.

[0083] By providing the support member 4 within the engagement deformation space, with one end of the support member 4 connected to the mounting seat 1 and the other end connected to the ends of all the engagement portions 2 that are away from the mounting seat 1, the structural strength and stability of the engagement portion 2 are further enhanced, making the connection strength and stability of the engagement structure elastically engaged in the sheet metal hole higher. This not only improves the assembly stability of the seal 20 on the vehicle body, resulting in a better sealing effect of the seal 20, but also further prevents the engagement portion 2 from being damaged during disassembly, extends the service life, and facilitates subsequent reuse. For example, after vehicle maintenance is completed, the removed seal 20 can be reassembled onto the vehicle body sheet metal 30 for use, reducing costs.

[0084] Specifically, the part of the support member 4 located within the engagement deformation space is spaced apart from each engagement portion 2, and the support member 4 does not interfere with the elastic deformation of the engagement portion 2.

[0085] In some embodiments, a second limiting portion for limiting the engagement portion 2 is provided on the support member 4. The second limiting portion is used to limit the engagement portion 2 elastically engaged in the sheet metal hole, avoiding the accidental detachment of the engagement portion 2 from the sheet metal hole and making the connection strength between the engagement portion 2 and the sheet metal hole higher.

[0086] Reference Figure 2 and Figure 6 As shown in Figure 1 and Figure 2The dimension in the X direction (in the figure) matches the aperture of the sheet metal hole. In this way, when the engaging section 21 elastically engages in the sheet metal hole, the side of the support member 4 facing the mounting seat 1 abuts against the hole wall of the sheet metal hole, increasing the contact area of the engaging portion 2 with the sheet metal hole, thereby further enhancing the connection strength and stability between the engaging portion 2 and the sheet metal hole, and making the connection of the seal 20 to the vehicle body sheet metal 30 more secure.

[0087] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 6 As shown, the second limiting portion is a limiting groove 5 provided on at least one side wall of the support member 4 along the first direction. The structure is simple and easy to manufacture. The limiting groove 5 is recessed in the direction facing the engaging deformation space, that is, the notch of the limiting groove 5 faces outward. When the engaging portion 2 is inserted through the sheet metal hole, a part of the limiting groove 5 is located in the sheet metal hole. With this setting, when the engaging section 21 elastically engages in the sheet metal hole, the limiting groove 5 has a limiting effect on their elastic engagement, enhancing the engaging strength of the engaging section 21 in the sheet metal hole and preventing the engaging section 21 from easily disengaging from the sheet metal hole.

[0088] In some implementation manners, limiting grooves 5 are provided on both side walls of the support member 4 in its first direction, for example.
