DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] In actual application, especially in the case of side impact of a vehicle, the inner panel of the door and the mounting frame are prone to be separated under the action of impact force. Once this happens, the inner panel of the door will move towards the inside of the vehicle, which will interfere with the normal deployment of the corresponding side airbag.

[0031] In order to solve or improve the problem that the inner panel of the door and the mounting frame are prone to be separated, the embodiments of the present application provide a water cutting mounting structure, a door body assembly and a carrier.

[0032] The embodiments of the present application will be described below in conjunction with Figures 1 to 2 The water cutting mounting structure provided in the embodiments of the present application will be described.

[0033] Specifically, the water cutting mounting structure comprises a mounting frame 1 and a first plate body 3.

[0034] The surface of the mounting frame 1 is provided with a recessed part 101 and a protruding part 102. Optionally, the recessed part 101 can be a groove, and the protruding part 102 can be a column structure, and the protruding direction of the protruding part 102 is consistent with the depth direction of the recessed part 101. The recessed part 101 is used for mounting an inner water cutting 2.

[0035] The first plate body 3 comprises a connecting part 301 and a clamping part 302. The first plate body 3 is an inner panel of a door. The connecting part 301 and the clamping part 302 are connected to each other, and the connecting part 301 and the clamping part 302 are arranged at an angle, and optionally, the included angle between the connecting part 301 and the clamping part 302 is in the range of 75°-110°, for example, the connecting part 301 and the clamping part 302 are perpendicular.

[0036] At least part of the clamping part 302 is arranged in the recessed part 101, the connecting part 301 is provided with a limiting hole 3011 through which the protruding part 102 passes, and the protruding part 102 is arranged in the limiting hole 3011. Along the direction perpendicular to the protruding direction of the protruding part 102, the limiting hole 3011 and the protruding part 102 are limited to each other, or in other words, along the surface of the mounting frame 1 provided with the protruding part 102, the limiting hole 3011 and the protruding part 102 are limited to each other.

[0037] In the embodiment, when the water-cut mounting structure is arranged on the door body, the opening of the recessed portion 101 faces downward or the recessed portion 101 is inclined downward, and correspondingly, the convex portion 102 faces downward or is inclined downward, so that the impact force generated by the side collision is arranged at an angle with the direction in which the convex portion 102 protrudes.

[0038] Further, when subjected to the side impact force, the limiting cooperation between the convex portion 102 and the limiting hole 3011 can offset or absorb the impact load borne by the first plate body 3, prevent excessive relative movement between the first plate body 3 and the mounting frame 1, and thus maintain the stability of the overall structure of the door body and guarantee the normal unfolding space of the side air bag.

[0039] Similarly, since the recessed direction of the recessed portion 101 is consistent with the protruding direction of the convex portion 102, that is, the recessed direction of the recessed portion 101 is also arranged at an angle with the direction of the impact force generated by the side collision, when the clamping portion 302 is arranged inside the recessed portion 101, the mutual limiting formed between the side wall of the recessed portion 101 and the clamping portion 302 can also offset or absorb the impact load borne by the first plate body 3, so as to prevent excessive relative movement between the first plate body 3 and the mounting frame 1.

[0040] In addition, the inner water-cut 2 can be arranged in the recessed portion 101, and such a structure forms an embedded cooperation relationship between the inner water-cut 2 and the mounting frame 1, which can improve the mounting stability of the inner water-cut 2. The part of the inner water-cut 2 arranged outside the recessed portion 101 is in sliding contact and sealing cooperation with the glass window, which can guarantee the waterproof and dustproof functions.

[0041] In some embodiments of the utility model, the water-cut mounting structure further comprises an inner water-cut 2.

[0042] Part of the inner water-cut 2 is arranged in the recessed portion 101, and the part of the inner water-cut 2 arranged outside the recessed portion 101 is used for sliding contact and sealing cooperation with the glass window. It can be understood that the material of the inner water-cut 2 includes but is not limited to rubber, silicone and thermoplastic elastomer.

[0043] The clamping portion 302 is in abutment with the part of the inner water-cut 2 located in the recessed portion 101, for example, the end of the clamping portion 302 away from the connecting portion 301 extends into the recessed portion 101 and is in abutment with the inner water-cut 2. Further, the clamping portion 302 limits the inner water-cut 2 in the depth direction of the recessed portion 101, so as to limit the movement of the inner water-cut 2 outward from the recessed portion 101.

[0044] In the embodiment, the connecting portion 301 of the first plate body 3 is arranged in the recessed portion 101 and limits the inner water-cut 2, which can further improve the mounting stability of the inner water-cut 2 and avoid loosening and falling of the inner water-cut 2.

[0045] In some embodiments of the utility model, the connecting part 301 and the clamping part 302 are both plate bodies, and the connecting part 301 and the clamping part 302 are sheet metal integrated structures.

[0046] In the embodiment, the connecting part 301 and the clamping part 302 are sheet metal integrated structures, which avoids the weak points possibly caused by traditional connection methods such as welding or bolt connection. When a vehicle is subjected to a side impact, the integrated structure can better disperse and withstand the impact force, reducing the risk of deformation or fracture, thereby improving the overall strength and safety of the vehicle door. In addition, the integrated structure reduces the number of parts and assembly steps, reducing manufacturing complexity.

[0047] In some embodiments of the utility model, the protruding part 102 and the mounting bracket 1 are provided as an integrated structure. For example, the protruding part 102 and the mounting bracket 1 can be provided as an injection molded integrated structure or a welded integrated structure.

[0048] In the embodiment, the integrated structure makes the connection between the protruding part 102 and the mounting bracket 1 more secure, effectively preventing loosening or falling off during vehicle operation, especially when subjected to impact, thereby ensuring the stability of the water cutting mounting structure as a whole and facilitating the maintenance of the normal function of the door body under various working conditions.

[0049] In addition, the integrated structure reduces the number of parts and assembly steps, reducing manufacturing complexity, thereby enabling rapid and efficient production of parts, for example, more suitable for mass production. At the same time, the integrated structure can reduce material waste. For example, no additional connecting parts (such as bolts, nuts, glue, etc.) are needed, thereby reducing the cost of these auxiliary materials.

[0050] Of course, the protruding part 102 and the mounting bracket 1 are not limited to being provided as an integrated structure. For example, in other embodiments of the utility model, the protruding part 102 and the mounting bracket 1 can be detachably connected. Alternatively, the protruding part 102 can be threadedly connected to the mounting bracket 1, for example, the protruding part 102 is provided with external threads, and the mounting bracket 1 is provided with a threaded hole that threadedly cooperates with the protruding part 102.

[0051] In the embodiment, the detachable connection enables the protruding part 102 and the mounting bracket 1 to be designed and manufactured as independent modules, facilitating adjustment or optimization according to requirements. For example, different specifications or materials of the protruding part 102 or the mounting bracket 1 can be flexibly replaced according to different door structure or functional requirements.

[0052] In some embodiments of the utility model, the protruding part 102 is provided with a limiting part 103 on the portion passing through the connecting part 301, i.e. the limiting part 103 is provided on the side of the connecting part 301 away from the mounting bracket 1.

[0053] Further, along the direction in which the protruding portion 102 protrudes, the limiting portion 103 limits the connecting portion 301, so as to limit the movement of the connecting portion 301 away from the mounting frame 1 along the direction in which the protruding portion 102 protrudes, and also limit the movement of the limiting hole 3011 of the mounting frame 1 away from the connecting portion 301.

[0054] In the embodiment, by arranging the limiting portion 103 on the protruding portion 102, the connecting portion 301 and the mounting frame 1 are prevented from being separated from each other along the direction in which the protruding portion 102 protrudes.

[0055] For example, even if the vehicle is subjected to an impact such as a side impact, the connection between the first plate body 3 and the mounting frame 1 is still firm, and the mounting frame 1 is prevented from moving upward and being separated from the first plate body 3, so as to on the one hand ensure the limiting effect of the mounting frame 1 on the first plate body 3, prevent the first plate body 3 from moving in the direction of the vehicle interior, and ensure that the side airbag can be normally deployed, and on the other hand, reduce the safety hazards caused by the disconnection of components.

[0056] In some embodiments of the utility model, a split groove 1021 is arranged on the side wall of the protruding portion 102, the split groove 1021 penetrates one end of the protruding portion 102 away from the mounting frame 1, and divides the protruding portion 102 into at least two elastic arms 1022, and the limiting portion 103 is arranged on at least part of the elastic arms 1022.

[0057] For example, Figure 1 As shown, in the example that the split groove 1021 is arranged on the side wall of the protruding portion 102, along the protruding direction of the protruding portion 102, the split groove 1021 penetrates one end of the protruding portion 102 away from the mounting frame 1, and along the direction perpendicular to the protruding direction of the protruding portion 102, the split groove 1021 penetrates the opposite two side walls of the protruding portion 102, so as to divide the protruding portion 102 into two elastic arms 1022, and the limiting portion 103 is arranged on one of the elastic arms 1022. It can be understood that increasing the number of split grooves 1021 can also increase the number of elastic arms 1022.

[0058] In the embodiment, the elastic arm 1022 formed by the split groove 1021 has a certain elastic deformation capacity, and can be elastically deformed under the action of an external force. When the end of the protruding portion 102 provided with the limiting portion 103 penetrates the limiting hole 3011, the elastic arm 1022 is extruded and deformed, so that the protruding portion 102 can smoothly pass through the limiting hole 3011, thereby reducing the installation difficulty and improving the installation efficiency.

[0059] Further, after the limiting portion 103 passes through the limiting hole 3011, the elastic arms 1022 will automatically reset, so that the limiting portion 103 is accurately located on the side of the connecting portion 301 away from the mounting frame 1, thereby achieving precise limiting of the connecting portion 301. This automatic reset function does not require additional positioning operations, thereby ensuring the accuracy and stability of the installation.

[0060] In addition, the split groove 1021 divides the protruding portion 102 into a plurality of elastic arms 1022, which can disperse stress between the elastic arms 1022 when subjected to external force, thereby avoiding stress concentration in a certain part and causing structural damage. For example, when a vehicle is subjected to a side impact or the like, the elastic arms 1022 can absorb part of the energy through their deformation, thereby reducing damage to the mounting frame 1 and the connecting portion 301, and thus ensuring the firmness of the connection.

[0061] In some embodiments of the present application, the limiting portion 103 is provided in a tapered structure, and the cross-sectional area of the limiting portion 103 gradually increases from the end of the protruding portion 102 away from the connecting portion 301 to the end close to the connecting portion 301.

[0062] In the present embodiment, the tapered limiting portion 103 is easier to insert into the limiting hole 3011 of the first plate body 3 during installation, and the gradually increasing cross-sectional area can serve as a guide, making the installation process smoother. At the same time, the elastic arms 1022 formed by the split groove 1021 can deform inwardly when subjected to pressure, thereby further facilitating the insertion of the protruding portion 102 into the limiting hole 3011 and reducing the difficulty and time of installation.

[0063] Of course, the limiting portion 103 can be arranged on the side of the connecting portion 301 away from the mounting frame 1 by means other than setting the split groove 1021, for example, in some embodiments not shown, the limiting portion 103 is detachably connected to the protruding portion 102.

[0064] In the present embodiment, during the connection of the first plate body 3 and the mounting frame 1, the protruding portion 102 can be first inserted through the limiting hole 3011, and then the limiting portion 103 is installed on the part of the protruding portion 102 that has passed through the limiting hole 3011.

[0065] In this way, for different models or structures of the first plate body 3 and the mounting frame 1, the position of the limiting portion 103 can be adjusted or different specifications of the limiting portion 103 can be replaced as needed. The detachable connection makes such adjustment and replacement more convenient, without the need to redesign or modify the entire structure, thereby improving the versatility and adaptability of the product. In addition, the limiting portion 103 and the protruding portion 102 can be made of different materials (such as metal, plastic, etc.) to meet different performance requirements.

[0066] In some embodiments of the present utility model, the limiting part 103 can be threadedly connected with the protruding part 102, for example, the limiting part 103 is set as a limiting nut, and the outer wall of the protruding part 102 is provided with external threads threadedly matched with the limiting part 103.

[0067] In this embodiment, during installation, if fine adjustment of the relative position between the connecting part 301 and the mounting frame 1 is required, the protruding length of the protruding part 102 in the limiting hole 3011 can be accurately controlled by rotating the limiting nut, thereby realizing accurate adjustment of the position of the connecting part 301 to meet the accuracy requirements in different installation scenarios. In addition, when the thickness of the connecting part 301 or the mounting frame 1 changes, the change can be adapted by adjusting the position of the limiting nut on the protruding part 102.

[0068] Of course, the limiting part 103 can also be clamped and matched with the protruding part 102, for example, the limiting part 103 is provided with a clamping spring, and the protruding part 102 is provided with a clamping groove 201 for installing the limiting part 103.

[0069] In this embodiment, the clamping and matching allows the limiting part 103 to be quickly and accurately positioned and fixed at a predetermined position of the protruding part 102, which can improve the assembly efficiency. The clamping spring provides a firm mechanical locking mechanism through the close matching with the clamping groove 201, which can effectively prevent the limiting part 103 from loosening or falling off due to vibration or impact force, thereby enhancing the stability and reliability of the entire structure.

[0070] In addition, the design of the clamping spring and the clamping groove 201 is generally compact, which can minimize the demand for surrounding space on the premise of ensuring the function, so that the overall design is more compact and efficient, for example, it is more suitable for application scenarios with limited space.

[0071] In some embodiments of the present utility model, the water cutting installation structure further comprises a sealing gasket 4.

[0072] Specifically, the sealing gasket 4 is clamped between the connecting part 301 and the surface of the mounting frame 1 provided with the protruding part 102. And the sealing gasket 4 is provided with a through hole 401 through which the protruding part 102 passes.

[0073] In this embodiment, the sealing gasket 4 can effectively seal the gap between the mounting frame 1 and the connecting part 301, and the gap between the protruding part 102 and the limiting hole 3011, thereby preventing water, dust and the like from passing through the above-mentioned gaps and improving the waterproof and dustproof performance of the door body.

[0074] In addition, during actual use, the door body may be subjected to various vibrations and impacts. The sealing gasket 4 has a certain elasticity and can play a role in buffering and shock absorption, reducing direct collision and friction between the mounting frame 1 and the connecting part 301, reducing noise generated by vibration, and also protecting the surfaces of the mounting frame 1 and the connecting part 301, preventing surface scratches or damage caused by mutual extrusion and friction, thereby prolonging the service life of the components.

[0075] In addition, due to the limitations of the manufacturing process, there may be certain errors in the sizes of the mounting frame 1 and the connecting part 301. The presence of the sealing gasket 4 can compensate for these size errors to some extent, allowing the two to better fit and ensuring the stability and reliability of the installation.

[0076] In some embodiments of the present application, the portion of the inner water cutting 2 located in the recess 101 is provided with a clamping groove 201, the opening direction of the clamping groove 201 is consistent with the opening direction of the recess 101, and the clamping part 302 is arranged in the clamping groove 201.

[0077] In this embodiment, the clamping groove 201 and the recess 101 are consistent in direction, which can provide clear and accurate positioning for the clamping part 302. When installing, the clamping part 302 only needs to be aligned with the clamping groove 201 and pushed in, which can quickly realize the connection of the clamping part 302 and the inner water cutting 2, ensure the accuracy of the installation position, and reduce the adjustment and alignment time during installation.

[0078] In addition, the cooperation of the clamping part 302 and the clamping groove 201 can realize relatively close connection, effectively limit the movement of the inner water cutting 2 in the depth direction of the recess 101, and ensure that it will not be displaced or loosened due to external forces such as vibration and bumping, thereby ensuring the sealing performance and overall stability of the water cutting.

[0079] In some embodiments of the present application, a first protruding rib 202 is arranged on the inner wall of the clamping groove 201, and the first protruding rib 202 abuts against the clamping part 302.

[0080] In this embodiment, the first protruding rib 202 abuts against the clamping part 302, which can increase the contact points and friction between the clamping groove 201 and the clamping part 302. When the vehicle is subjected to vibration or external force during driving, this design can effectively prevent the clamping part 302 from sliding or shaking in the clamping groove 201, making the connection between the inner water cutting 2 and other components more stable, ensuring the reliability of the water cutting installation structure, and maintaining good sealing effect.

[0081] In addition, since the first convex rib 202 is in close abutment with the clamping portion 302, a small gap that may exist between the clamping groove 201 and the clamping portion 302 can be further filled, the possibility of external substances such as water and dust entering the vehicle through the gap is reduced, and the sealing performance of the vehicle door is improved, thereby keeping the vehicle interior clean and dry.

[0082] In some embodiments provided by the utility model, the water cutting installation structure further comprises a second plate body 5.

[0083] One end of the second plate body 5 is in abutment with the part of the inner water cutting 2 located in the recessed portion 101, and the second plate body 5 limits the inner water cutting 2 along the depth direction of the recessed portion 101. For example, the second plate body 5 is arranged on the side of the first plate body 3 away from the vehicle interior.

[0084] In the embodiment, through the cooperation of the second plate body 5 and the first plate body 3, the structural strength and protection effect of the door body can be improved. In addition, the second plate body 5 is arranged on the side of the first plate body 3 away from the vehicle interior, so that the first plate body 3 can limit the second plate body 5, thereby avoiding excessive intrusion of the second plate body 5 into the vehicle interior in the event of a side collision.

[0085] In addition, the first plate body 3 and the second plate body 5 jointly limit the water cutting, thereby increasing the constraint points and constraint degree of the water cutting, and making the water cutting more stable after installation. Whether in the event of vibration, bumping or other external force, the water cutting can be firmly fixed in place, thereby reducing the risk of sealing failure due to loosening or displacement, and improving the reliability and stability of the water cutting installation structure.

[0086] In addition, the double-limiting mechanism of the first plate body 3 and the second plate body 5 ensures that the inner water cutting 2 is in close contact with the recessed portion 101, thereby reducing the existence of gaps and further improving the sealing effect of the vehicle door system.

[0087] In some embodiments provided by the utility model, the second plate body 5 extends into the recessed portion 101, and a second convex rib 203 is further arranged on the inner wall of the recessed portion 101, wherein the second convex rib 203 is in abutment with the side of the second plate body 5 away from the first plate body 3. Correspondingly, the first convex rib 202 is in abutment with the side of the clamping portion 302 away from the second plate body 5.

[0088] In the embodiment, the second convex rib 203 is in abutment with the second plate body 5, thereby increasing the contact points and friction between the clamping groove 201 and the second plate body 5. When vibration or external force occurs during vehicle driving, this design can effectively prevent the second plate body 5 from relatively sliding or shaking in the clamping groove 201, thereby making the connection between the inner water cutting 2 and other components more stable, ensuring the reliability of the water cutting installation structure, and maintaining good sealing effect.

[0089] In addition, since the second convex rib 203 is in close contact with the second plate body 5, the small gap that may exist between the card slot 201 and the second plate body 5 can be further filled, and the possibility of water, dust and other external substances entering the vehicle through the gap is reduced, thereby improving the sealing performance of the door and keeping the vehicle interior clean and dry.

[0090] According to the embodiments of the utility model, on the other hand, a door assembly is also provided, which comprises the water-cut installation structure as above.

[0091] It can be understood that the door assembly comprises the water-cut installation structure, and therefore comprises all the advantages of the water-cut installation structure, which will not be described again.

[0092] Further, the door assembly further comprises a door inner trim panel skeleton, which is connected with the mounting frame 1.
