Description

Technical Field

[0001] The present invention relates to the technical field of door seals, and particularly to a middle seal for converting a top-hinged door into a double-leaf door. Background Art

[0002] With the rapid development of the logistics industry, the market share of van trucks is increasing. The rear door of the cargo compartment is generally a top-hinged door. Although the overall structure is simple, it is not suitable for all working scenarios. The commonly used top-hinged door structure does not meet the user's needs for loading and unloading goods. For users, double-leaf doors are more convenient for transporting goods and have higher work efficiency. Therefore, in response to the models converted from top-hinged doors to double-leaf doors, it is crucial to adopt a new design concept to make the seals for such double-leaf doors at present.

[0003] For example, the patent with the publication number N106335353A discloses an automobile door seal on January 18, 2017, which includes a strip brush, a lip, a fixing strip, and a sealing clamping strip. There is a cavity in the middle of the fixing strip and the sealing clamping strip respectively. One side of the fixing strip is connected to one side of the sealing clamping strip. A support strip is connected above the connecting part of the fixing strip and the sealing clamping strip. The lip is connected to the middle of the support strip and forms a certain angle with the support strip. The strip brush is connected to the upper part of the support strip and forms a certain angle with the support strip. The strip brush and the lip are on the same side of the sealing clamping strip. When the above-mentioned disclosed seal is used, the seal cannot be stably installed on the door, and the seal is likely to fall off after long-term use, with poor practicability. Summary of the Invention

[0004] The purpose of the present invention is to provide a middle seal for converting a top-hinged door into a double-leaf door with stable installation. The present invention ensures the stable installation of the seal on the door by connecting the first joint angles at both ends of the seal to the door sheet metal through the first installation buckles and adhesive fixing columns, and connecting the second installation buckles on the second joint angles to the door plastic parts, with higher practicability.

[0005] To achieve the above purpose, the technical solution adopted by the present invention to solve its technical problems is: a middle seal for converting a top-hinged door into a double-leaf door, including a seal. One end of the seal is provided with a first joint angle connected to the door sheet metal, and the other end of the seal is provided with a second joint angle connected to the door plastic part. The first joint angle is provided with a first installation buckle connected to the door sheet metal, and the first joint angle is provided with an adhesive fixing column connected to the door sheet metal. The second joint angle is provided with a second installation buckle connected to the door plastic part.

[0006] The seal includes a U-shaped strip. One side of the U-shaped strip is provided with a lateral sealing bubble tube. A card slot is arranged inside the U-shaped strip, and a first convex strip and a second convex strip are respectively arranged on the two slot walls of the card slot.

[0007] The first rib is obliquely arranged, and the lateral sealing bubble tube is arranged on one side of the sealing strip away from the first joint angle and the second joint angle.

[0008] At the opening of the U-shaped strip, there are a first lip and a second lip that open outward. The length of the first lip is greater than that of the second lip, and the first lip is arranged on one side of the sealing strip close to the first joint angle and the second joint angle.

[0009] On the first joint angle, there is a side seat connected to the sealing strip. The cross-section of the side seat is the same as that of the sealing strip. The adhesive fixing column is arranged on the side seat. There is a water-blocking strip on the side seat. One end of the water-blocking strip is flush with the length direction of the first joint angle, and the other end of the water-blocking strip extends to one side of the lateral sealing bubble tube. There is a lapping platform at the connection of the adhesive fixing column and the first joint angle.

[0010] The first joint angle includes a first connection surface, a second connection surface, and a third connection surface. The first connection surface, the second connection surface, and the third connection surface are connected in sequence in a stepped shape. The side seat is connected to the first connection surface. On the third connection surface, there are a first cross plate and a second cross plate connected to the side plate. The first cross plate and the second cross plate are parallel to each other. There is a first card slot between the first cross plate and the second connection surface, and a second card slot between the first cross plate and the second cross plate. The first card slot and the second card slot are clamped with the door sheet metal. There is a limit protrusion on the second cross plate, and the first lip of the sealing strip is connected to the second cross plate.

[0011] The second joint angle includes a mounting seat connected to the sealing strip. There is a convex seat on the mounting seat. There are sinking grooves on both sides of the convex seat for clamping with automotive plastic parts. The second mounting buckle is arranged on the side wall of the sinking groove.

[0012] There is a mounting groove on the convex seat, and the opening of the mounting groove faces the opposite direction to the opening of the sinking groove.

[0013] Reinforcing ribs are arranged in the mounting groove.

[0014] The sealing strip, the first joint angle, and the second joint angle are integrally formed parts.

[0015] The beneficial effects of the present invention are:

[0016] The sealing strip is clamped with the door edge. After being clamped with the sheet metal on the door through the first joint angle on the sealing strip, it is reinforced through the first mounting buckle and the adhesive fixing column. After being clamped with the plastic parts on the door through the second joint angle on the sealing strip, it is reinforced through the second mounting buckle, thereby realizing the stable installation of the entire sealing strip on the door. And after installation, the sealing strip is not easy to shake, thus ensuring that the sealing strip stably seals the door, with higher practicability;

[0017] A water retaining strip is provided on the side seat at the first joint corner. Under the guiding action of the water retaining strip, rainwater flows outside the vehicle door, thereby increasing the sealing performance of the entire sealing strip. The first joint corner is stably installed on the vehicle door by being clamped with the vehicle door sheet metal through the first clamping groove, the second clamping groove, and the overlapping platform provided on the first joint corner.

[0018] After the second joint corner is clamped with the vehicle door plastic part through the sunken groove provided on the second joint corner, the stable installation of the second joint corner is realized. Moreover, three second installation buckles provided on the three side walls of the sunken groove perform a limiting function on the second joint corner, thereby ensuring the stable installation work of the second joint corner on the vehicle door.

Detailed Embodiments

[0027] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. 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] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.

[0029] As Figure 1 shown, the middle seal strip of the upward-opening converted double-door includes a seal strip 1. One end of the seal strip 1 is provided with a first joint angle 2 connected to the door sheet metal, and the other end of the seal strip 1 is provided with a second joint angle 3 connected to the door plastic part. The first joint angle 2 is provided with a first installation buckle 4 connected to the door sheet metal, and the first joint angle 2 is provided with an adhesive fixing column 5 connected to the door sheet metal. The surface of the adhesive fixing column 5 is coated with an adhesive to achieve the fixation of the first joint angle 2 and the door sheet metal. The second joint angle 3 is provided with a second installation buckle 6 connected to the door plastic part. In this embodiment, both the first installation buckle 4 and the second installation buckle 6 are provided with three, and riveting holes for cooperating with rivets are respectively provided on the door sheet metal and the door plastic.

[0030] During use, after the first joint angle 2 is snap-connected to the door sheet metal, the first joint angle 2 is installed through the first installation buckle 4. An adhesive is coated on the adhesive fixing column 5 on the first joint angle 2 to bond the first joint angle 4 to the door sheet metal. After the second joint angle 3 is snap-connected to the door plastic, the second joint angle 3 is stably connected to the door plastic through the second installation buckle 6. The seal strip 1 is snap-connected and wrapped around the edge of the door, so as to realize the stable installation of the entire seal strip 1 on the door, and the seal strip is not easy to shake after installation, thus ensuring that the seal strip stably seals the door, and the practicability is higher.

[0031] Referring to Figure 1, the sealing strip 1 includes a U-shaped strip 101. One side of the U-shaped strip 101 is provided with a lateral sealing bubble tube 102. A clamping groove 103 is arranged inside the U-shaped strip 101. The arrangement of the clamping groove 103 facilitates the clamping of the vehicle door into the U-shaped strip 101, thereby realizing the clamping connection between the sealing strip 1 and the vehicle door. Therefore, a first rib 104 and a second rib 105 are respectively arranged on the two groove walls of the clamping groove 103. After the edge of the vehicle door is clamped into the clamping groove 103, the first rib 104 and the second rib 105 are deformed, and further ensure that the first rib 104 and the second rib 105 stably seal the clamping groove 103, thereby preventing sundries or water from flowing into the clamping groove 103. When the edge of the vehicle door is stuck in the clamping groove 103 of the U-shaped strip 101, the lateral sealing bubble tube 102 at the side end of the U-shaped strip 101 plays a sealing role when installed on the vehicle door, thereby ensuring a better sealing effect of the entire vehicle door after it is closed. And in this embodiment, the cross-section of the lateral sealing bubble tube 102 is annular, thereby reducing the weight of the lateral sealing bubble tube 102 and facilitating the deformation of the lateral sealing bubble tube 102 to achieve the sealing work.

[0032] Refer to Figure 2 , the first rib 104 is obliquely arranged. Thus, when the edge of the vehicle door is inserted into the clamping groove 103, after the first rib 104 is deformed, it abuts against the surface of the vehicle door. In this embodiment, the length of the obliquely arranged first rib 104 is greater than that of the second rib 104, so as to ensure that the second rib 105 is extruded by the deformed first rib 104 when the vehicle door is in the clamping groove 103, thereby increasing the contact friction force when the clamping groove 103 is connected to the vehicle door, and thus ensuring the stable installation of the vehicle door in the clamping groove 103. And the first rib 104 faces the inner side of the clamping groove 103. The lateral sealing bubble tube 102 is arranged on one side of the sealing strip 1 far from the first joint angle 2 and the second joint angle 3, so as to ensure that the lateral sealing bubble tube 102 is arranged inside the vehicle door after the sealing strip 1 is installed, thereby realizing the elastic support and sealing work of the lateral sealing bubble tube 102.

[0033] Furthermore, at the opening of the U-shaped strip 101, a first lip 106 and a second lip 107 that open outward are provided. The arrangement of the first lip 106 and the second lip 107 facilitates the convenient installation of the sealing strip 1 in the clamping groove 103, thereby increasing the installation efficiency of the sealing strip 1. Specifically, the length of the first lip 106 is greater than that of the second lip 107. The first lip 106 is arranged on the side of the sealing strip 1 close to the first joint angle 2 and the second joint angle 3. By connecting the first lip 106 with a longer cross-sectional length to the first joint angle 2 and the second joint angle 3, the strength of the sealing strip 1 after being integrally formed with the first joint angle 2 and the second joint angle 3 is increased.

[0034] Refer to Figure 2 - 4, a side seat 7 connected to the sealing strip 1 is provided on the first joint corner 2. The cross-section of the side seat 7 is the same as that of the sealing strip 1, facilitating the stable connection between the first joint corner 2 and the sealing strip 1 after the side seat 7 and the sealing strip 1 are formed. Specifically, an adhesive fixing post 5 is provided on the side seat 7, and the adhesive is coated on the adhesive fixing post 5 for installation work. In this embodiment, the adhesive fixing post 5 is strip-shaped, and the length direction of the adhesive fixing post 5 is flush with the length direction of the sealing strip 1. Further, a water blocking strip 8 is provided on the side seat 7. One end of the water blocking strip 8 is flush with the length direction of the first joint corner 2, and the other end of the water blocking strip 8 extends to one side of the lateral sealing bubble tube 102. When rainwater falls on the first joint 2, the rainwater flows outside the vehicle door under the guiding action of the water blocking strip 8, thereby increasing the sealing performance of the entire sealing strip 1. A lapping platform 9 is provided at the connection between the adhesive fixing post 5 and the first joint corner 2, and the lapping platform 9 is snap-connected to the vehicle door sheet metal, ensuring the stable installation of the first joint corner 2 on the vehicle door.

[0035] The first joint corner 2 includes a first connecting surface 201, a second connecting surface 202, and a third connecting surface 203. The first connecting surface 201, the second connecting surface 202, and the third connecting surface 203 are connected in sequence to form a stepped shape, ensuring the stable connection between the first joint corner 2 formed by the first connecting surface 201, the second connecting surface 202, and the third connecting surface 203 and the vehicle door sheet metal. The side seat 7 is connected to the first connecting surface 201. A first cross plate 10 and a second cross plate 11 connected to the side plate 7 are provided on the third connecting surface 203. The first cross plate 10 and the second cross plate 11 are parallel to each other. A first slot 12 is provided between the first cross plate 10 and the second connecting surface 202, and a second slot 13 is provided between the first cross plate 10 and the second cross plate 11. The first slot 12 and the second slot 13 are snap-connected to the vehicle door sheet metal. Protrusions matching the first slot 12 and the second slot 13 are provided on the vehicle door sheet metal, and the protrusions on the vehicle door sheet metal are extended into the first slot 12 and the second slot 13, realizing the stable installation work between the vehicle door sheet metal and the first joint corner 2. A limiting protrusion 14 is provided on the second cross plate 11, and the limiting protrusion 14 guides the snap connection between the second cross plate 11 and the vehicle door sheet metal, ensuring that the first joint corner 2 is accurately inserted onto the vehicle door sheet metal. Specifically, the first lip 106 of the sealing strip 1 is connected to the second cross plate 11, increasing the connection strength between the sealing strip 1 and the first joint corner 2.

[0036] In this embodiment, there are three first mounting buckles 4, which are arranged on the second connection surface 202, the third mounting surface 203 and the side seat 7. The first mounting buckles 4 face the first card slot 12 and the second card slot 13 on the side seat 7, so as to ensure the riveting work after the door sheet metal is clamped with the first card slot 12 and the second card slot 13. One end of the adhesive fixing column 5 extends to the side seat 7, and the other end of the adhesive fixing column 5 extends to the first connection surface 201 of the first connection angle 2. There are two overlapping platforms 9, which are arranged at the connection between the side seat 7 and the first connection surface 201.

[0037] Referring to Figure 6 and 7 , the second connection angle 3 includes a mounting seat 301 connected to the sealing strip 1. There is a convex seat 302 on the mounting seat 301. There are sinking grooves 303 for clamping with automotive plastic parts on both sides of the convex seat 302. The second mounting buckles 6 are arranged on the side walls of the sinking grooves 303. The sinking grooves 303 are convenient for clamping with the door plastic parts, so that the door plastic parts can be installed through the second mounting buckles 6 after being clamped. Specifically, there are two sinking grooves 303, which are symmetrically arranged on both sides of the convex seat 302, and the sinking grooves 303 are provided with lateral openings, so as to facilitate the clamping of the door plastic parts. Specifically, there are three second mounting buckles 6, and the three second mounting buckles 6 fix the second connection angle 3 in three directions respectively, that is, limit the x, y and z directions. Referring to Figure 6 , there is one second mounting buckle 6 on the bottom wall and the side wall of the sinking groove 303 respectively, and there is an extension plate on the other side wall of the sinking groove 303, and there is one second mounting buckle 6 on the extension plate.

[0038] Referring to Figure 7 , there is a mounting groove 304 on the convex seat 302. The mounting groove 304 is arranged at the middle position between the two sinking grooves 303, and the opening of the mounting groove 304 is opposite to the opening of the sinking grooves 303. Thus, the mounting groove 304 reduces the weight of the convex seat 302 and is also convenient for the convenient installation of the second mounting buckles 6 on the side walls of the sinking grooves 303.

[0039] There are reinforcing ribs 305 in the mounting groove 304, so as to increase the strength of the mounting groove 304, and further increase the strength of the convex seat 302 and the second connection angle 3. Specifically, there are three reinforcing ribs 305 in the mounting groove 304.

[0040] The sealing strip 1, the first connection angle 2 and the second connection angle 3 are integrally formed parts, so as to realize the convenient molding of the whole middle sealing strip. In this embodiment, the sealing strip 1 is first composite extruded and formed, and then the two ends of the formed sealing strip are placed in different models in turn for the formation of the first connection angle 2 and the second connection angle 3.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
