Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts, in particular to a tailgate threshold structure and a vehicle. Background Art

[0002] The threshold of a car tailgate is usually equipped with a lock ring seat body on the tailgate sheet metal body, and the lock ring on the lock ring seat body is engaged with the lock buckle body on the car tailgate to achieve locking when the car tailgate is closed. In rainy days and other environments with high air humidity, during the process of opening and closing the car tailgate, the lock buckle body on the car tailgate will carry some raindrops and bring the raindrops into the installation position between the tailgate sheet metal body and the lock ring seat body. Since this position is located inside the tailgate trim, the raindrops that enter are not easy to evaporate. After a long time, it is easy to cause rust at the connection position between the tailgate sheet metal body and the lock ring seat body, which will reduce the installation strength of the lock ring and ultimately reduce the stability of the car tailgate lock.

[0033] See also Figures 1 to 12The utility model provides a tailgate threshold structure and a vehicle. The tailgate threshold structure is provided with a contact gap 301 penetrating the abutting area 300 formed by the contact between the tailgate sheet metal body 100 and the lock ring seat body 200, so that the contact gap 301 can form an airflow channel inside the abutting area 300, accelerate the circulation of airflow at the position of the abutting area 300, promote the volatilization of residual moisture at the position of the abutting area 300, reduce the probability of water accumulation in the abutting area 300, and further reduce the probability of rust at the connection position of the tailgate sheet metal body 100 and the lock ring seat body 200.

[0034] The tailgate threshold structure provided by the utility model is installed at the rear position of the vehicle body 700 to form a matching connection relationship with the tailgate 600 of the vehicle when the tailgate 600 of the vehicle is closed. The tailgate threshold structure includes a tailgate sheet metal body 100 and a lock ring seat body 200. The tailgate sheet metal body 100 can be integrally stamped and connected with the vehicle body 700, or it can be a separate sheet metal part, which is fixedly connected to the vehicle body 700 by welding or bolts. Preferably, in this embodiment, the tailgate sheet metal body 100 is an integral structure stamped and formed with the vehicle body 700. The tailgate sheet metal body 100 is provided with a first surface 101, and the direction of the first surface 101 is not limited, for example, it can be toward the side wall direction of the vehicle body 700, or it can be toward the top direction of the vehicle body 700, etc. The first surface 101 can be a horizontal surface, an inclined surface, or a combination of a horizontal surface and an inclined surface. Preferably, in this embodiment, the first surface 101 is roughly toward the top direction of the vehicle body, so that it is convenient to install other components on the first surface 101.

[0035] The lock ring seat body 200 is fixedly mounted on the tailgate sheet metal body 100, and the fixed connection method can be bolt fixed connection, groove and protrusion clamping connection, welding fixed connection, etc. Preferably, in this embodiment, the lock ring seat body 200 is fixedly connected to the tailgate sheet metal body 100 by connecting bolts 230. Specifically, the lock ring seat body 200 includes a mounting plate 220 and a lock ring 210. The mounting plate 220 is provided with a mounting through hole 221, and the tailgate sheet metal body 100 is correspondingly provided with a threaded hole 102. The connecting bolt 230 passes through the mounting through hole 221 and is tightened in the threaded hole 102 to achieve a fixed connection between the lock ring seat body 200 and the tailgate sheet metal body 100. The mounting through hole 221 can be a long hole, or a circular through hole, etc., to meet the installation requirements of the connecting bolt 230. Preferably, in the present embodiment, the mounting through hole 221 is a long hole structure, which facilitates the adjustment of the mounting position of the locking ring seat body 200 and can improve the assembly efficiency of the locking ring seat body 200 .

[0036] The second surface 222 is provided on the side of the mounting plate 220 facing the first surface 101. After the lock ring seat 200 is fixedly connected to the tailgate sheet metal body 100, the second surface 222 contacts the first surface 101 and forms the abutment area 300. The lock ring 210 is a nearly U-shaped structure. The open end of the lock ring 210 passes through the abutment area 300 along the thickness direction of the mounting plate 220 and is fixedly connected to the tailgate sheet metal body 100 by threads. The ring body end of the lock ring 210 is located on the side of the mounting plate 220 facing the top of the vehicle body, so that when the car tailgate 600 is closed, it is matched with the lock body 601 installed on the car tailgate 600 to achieve the locking between the car tailgate 600 and the vehicle body.

[0037] It should be noted that, in order to improve the aesthetics of the installation position of the lock ring 210, a housing 240 may be further provided on the side of the lock ring seat 200 away from the first surface 101. The housing 240 is provided at the middle position of the two connecting bolts 230 and is fixedly connected to the mounting plate 220. The fixed connection method may be an adhesive connection or a bolted connection, etc. An approximately L-shaped cavity is formed on the side of the housing 240 away from the mounting plate 220. The bottom wall of the cavity is provided with a lock ring hole 241 for the lock ring 210 to pass through. Parts such as a buffer block 250 may be provided on the side wall of the cavity.

[0038] The abutment area 300 formed by the contact between the second surface 222 and the first surface 101 is provided with a contact gap 301 that penetrates the abutment area 300. The forming method of the contact gap 301 is not limited, for example, the contact gap 301 may be formed by opening a groove on the first surface 101 or the second surface 222, or by providing a local protrusion structure 400 on the first surface 101 or the second surface 222 to form the contact gap 301, or by processing a corrugated structure on the first surface 101 or the second surface 222 to form the contact gap 301, and other forming methods. The size and shape of the contact gap 301 are not limited, as long as the contact support strength between the first surface 101 and the second surface 222 can be met, and the connection stability between the lock ring seat body 200 and the tailgate sheet metal body 100 can be ensured.

[0039] In an environment with high air humidity such as rainy days, during the process of opening and closing the car tailgate 600, the lock body 601 on the car tailgate 600 will carry some raindrops and bring the raindrops into the lock ring 210 position of the lock ring seat 200. The water droplets at this position can easily penetrate into the abutment area 300 formed between the first surface 101 and the second surface 222 through the installation gap between the lock ring 210 and the mounting plate 220, and then form water accumulation inside the abutment area 300. After a long time, it is easy to cause rust on the surface of the connecting plate at the abutment area 300 and the tailgate sheet metal body 100. In this embodiment, by setting a contact gap 301 that runs through the abutment area 300, the contact gap 301 can form an airflow channel inside the abutment area 300, accelerate the circulation of airflow at the abutment area 300, and promote the timely volatilization of moisture that penetrates into the abutment area 300, thereby reducing the probability of water accumulation in the abutment area 300, and further reducing the probability of rust on the surface where the tailgate sheet metal body 100 contacts the connecting plate, thereby correspondingly improving the installation strength of the lock ring 210 and the locking stability of the automobile tailgate 600.

[0040] In an example of the tailgate threshold structure of the utility model, the abutment area 300 includes a plurality of protruding structures 400 arranged on the first surface 101, and the plurality of protruding structures 400 form a plurality of local supports between the first surface 101 and the second surface 222, and at least a partial contact gap 301 is formed between adjacent local supports. The plurality of protruding structures 400 can be arranged in a straight line, an arc line, or a curve line, etc.; the specific shape of the protruding structure 400 can also be selected in a variety of ways, such as a cylindrical protruding structure 400, a conical protruding structure 400, or a hemispherical protruding structure 400, etc. Preferably, in the present embodiment, the protruding structure 400 is a structure approximating a conical surface. In this way, the contact area between the protruding structure 400 and the second surface 222 can be reduced as much as possible, and the volume of the contact gap 301 can be increased accordingly, which is more conducive to accelerating the volatilization of the water inside the abutment area 300. In this embodiment, a protruding structure 400 is provided on the first surface 101, so that a contact gap 301 can be formed in the abutting area 300, which is beneficial to accelerate the volatilization of moisture inside the abutting area 300 and reduce the probability of rust at the position of the abutting area 300; it can also enhance the supporting strength of the first surface 101, thereby improving the installation strength of the locking ring seat body 200 on the tailgate sheet metal body 100.

[0041] In some other embodiments, a plurality of protrusion structures 400 may be provided on the second surface 222, so that the protrusion structures 400 may also form a local support between the first surface 101 and the second surface 222 to at least form a part of the contact gap 301, achieving the same beneficial effect as the above embodiment. In other embodiments, part of the protrusion structures 400 may be provided on the first surface 101, and part of the protrusion structures 400 may be provided on the second surface 222, so that a local support may also be formed between the first surface 101 and the second surface 222, and a contact gap 301 may be formed in the abutting area 300, thereby reducing the rust generated in the abutting area 300.

[0042] In an example of the tailgate threshold structure of the present invention, the abutting area 300 includes a first bonding area 310 and a second bonding area 320 formed when the first surface 101 and the second surface 222 abut against each other. Fig.10 The first bonding area 310 and the second bonding area 320 are respectively arranged at the two ends of the abutting area 300. The first bonding area 310 and the second bonding area 320 can be an integral annular structure, or a plurality of dispersed local surface structures, etc., specifically, the abutting area requirement between the first surface 101 and the second surface 222 is met. The installation position of the lock ring 210 and the tailgate sheet metal body 100 is located between the first bonding area 310 and the second bonding area 320, and the protruding structure 400 is also arranged between the first bonding area 310 and the second bonding area 320. The protruding structure 400 is located between the first bonding area 310 and the second bonding area 320, which may mean that the protruding structure 400 is located in the middle of the first bonding area 310 and the second bonding area 320, or it may mean that the protruding structure 400 is arranged close to one side of the first bonding area 310 or the second bonding area 320, and there is no specific limitation on this.

[0043] In the present embodiment, the locking ring 210 and the protruding structure 400 are both arranged between the first fitting area 310 and the second fitting area 320. This not only ensures that the two sides of the locking ring 210 have a stable connection, thereby improving the tightness of the fitting between the locking ring 210 and the tailgate sheet metal body 100 and reducing the amount of water that penetrates into the abutment area 300 from the installation position of the locking ring 210; it also makes the contact gap 301 close to the installation position of the locking ring 210 and the tailgate sheet metal body 100, so that the moisture that penetrates into the abutment area 300 can be evaporated in time, further reducing the probability of rust at the abutment position between the first surface 101 and the second surface 222.

[0044] In an example of the tailgate threshold structure of the present invention, the raised structure 400 is disposed on the first surface 101 and protrudes toward the second surface 222. The raised structure 400 may protrude toward the second surface 222 in a direction perpendicular to the first surface 101, or may protrude obliquely toward the second surface 222 in a direction at a certain inclination angle to the first surface 101, etc. Disposing the raised structure 400 on the first surface 101 can not only improve the supporting strength of the first surface 101, but also facilitate processing and forming. The height of the raised structure 400 protruding from the first surface 101 is any value within the range of 0.5 to 1.2 mm, for example, it may be 0.5 mm, 0.8 mm or 1.2 mm, etc. The height of the raised structure 400 protruding from the first surface 101 refers to the height dimension of the raised structure 400 protruding from the first surface 101 along the thickness direction of the tailgate sheet metal body 100, such as Fig.12 In this embodiment, by limiting the height of the protruding structure 400 protruding from the first surface 101 to within the range of 0.5 to 1.2 mm, the protruding structure 400 can be easily formed, the processing cost of the protruding structure 400 can be reduced, and a better contact gap 301 can be obtained between the first surface 101 and the second surface 222, so that the moisture infiltrated into the abutting area 300 can be volatilized in time.

[0045] In an example of the tailgate threshold structure of the present invention, the raised structure 400 includes a first raised portion 410 and a plurality of second raised portions 420 disposed on the surface of the first raised portion 410, wherein the second raised portions 420 protrude from the surface of the first raised portion 410 and abut against the second surface 222. The specific structures of the first raised portion 410 and the second raised portion 420 are not limited, and may be, for example, a substantially rectangular parallelepiped structure, a substantially cylindrical structure, or a substantially triangular structure, as long as the second raised portion 420 can be disposed on the surface of the first raised portion 410 and abut against the second surface 222.

[0046] The utility model provides a first protrusion 410 and a second protrusion 420 so that the height of the protrusion structure 400 changes in a stepped manner along the thickness direction of the tailgate sheet metal body 100, which can not only improve the supporting strength and supporting stiffness of the protrusion structure 400 and ensure the stable abutment between the first surface 101 and the second surface 222, but also reduce the contact area between the protrusion structure 400 and the second surface 222. Not only is a contact gap 301 formed between adjacent protrusion structures 400, but also a contact gap 301 is formed between a single protrusion structure 400 and the second surface 222, thereby further promoting the timely volatilization of moisture that has penetrated into the abutment area 300.

[0047] In an example of the tailgate threshold structure of the present invention, the first protrusion 410 is a long strip structure, along the width direction of the first surface 101 (eg Fig.10 The first convex portion 410 is arranged in an inclined shape; the specific inclination angle and inclination direction of the first convex portion 410 are not limited, as long as the length direction of the first convex portion 410 is symmetrical with the central axis ZZ of the length direction of the first surface 101 (as shown in FIG. Fig.11 The plurality of second convex portions 420 are arranged in sequence along the length direction of the first convex portion 410. The sequential arrangement may refer to the plurality of second convex portions 420 being arranged in sequence in a straight line along the length direction of the first convex portion 410, or may refer to the plurality of second convex portions 420 being arranged in sequence in a curved line along the length direction of the first convex portion 410, and other arrangement methods. Preferably, in the present embodiment, the plurality of second convex portions 420 are arranged in a straight line along the length direction of the first convex portion 410, so as to facilitate the positioning and processing of the second convex portions 420 on the first convex portion 410. The number of second convex portions 420 provided on each first convex portion 410 may be two, three, four, etc. Preferably, in the present embodiment, two second convex portions 420 are provided on each first convex portion 410.

[0048] In this embodiment, along the width direction of the tailgate sheet metal body 100, the first convex portion 410 of the long strip structure is extended obliquely from the side of the first surface 101 close to the rear of the vehicle to the side of the first surface 101 away from the rear of the vehicle. Specifically, Fig.11 As shown, the extension direction of the first protrusion 410 forms a certain angle with the symmetrical central axis ZZ of the length direction of the tailgate sheet metal body 100, and the multiple second protrusions 420 are arranged in sequence along the length direction of the first protrusion 410. Such an arrangement can not only make the supporting force of the protrusion structure 400 on the second surface 222 more stable and reliable when the first surface 101 and the second surface 222 are abutted and pressed, thereby ensuring the stability of the contact gap 301 between the first surface 101 and the second surface 222, and ensuring the smoothness of the airflow inside the contact gap 301; but also enable the external airflow to flow more into the contact gap 301 between the multiple second protrusions 420 on the first protrusion 410, which is beneficial to further accelerate the volatilization rate of moisture that penetrates into the abutment area 300.

[0049] In an example of the tailgate threshold structure of the present invention, along the length direction of the tailgate sheet metal body 100 (eg Fig.10 In the X-axis direction, two groups of protrusion structures 400 are arranged at intervals between the first bonding area 310 and the second bonding area 320; the two groups of protrusion structures 400 can be symmetrically arranged or asymmetrically arranged. Fig.10The first protrusions 410 of the two groups of protrusion structures 400 are arranged in an inclined shape, and the spacing between the two first protrusions 410 gradually increases from the side close to the rear of the vehicle to the side away from the rear of the vehicle. The two first protrusions 410 can be distributed in a regular figure-eight shape, or can be distributed in an inclined approximate figure-eight shape, or any distribution structure that satisfies the gradual increase from the side close to the rear of the vehicle to the side away from the rear of the vehicle. Preferably, in this embodiment, the two groups of first protrusions 410 are distributed in a regular figure-eight shape, which facilitates the molding process of the first protrusions 410 and the positioning process between the two groups of first protrusions 410.

[0050] In this embodiment, by adopting a structural setting in which the distance between the two first protrusions 410 gradually increases from the side close to the rear of the vehicle to the side away from the rear of the vehicle, the two first protrusions 410 can be combined with the first surface 101 and the second surface 222 to form an approximately trumpet-shaped structure. Such a structure can relatively increase the airflow velocity entering the contact gap 301 between adjacent first protrusions 410, thereby accelerating the volatilization rate of moisture that penetrates into the abutment area 300, and further reducing the probability of rust in the abutment area 300.

[0051] In an example of the tailgate threshold structure of the present invention, two groups of protruding structures 400 are symmetrically arranged between the first fitting area 310 and the second fitting area 320, and the first protrusions 410 of the two protruding structures 400 form an inclined angle α (such as Fig.11 As shown in FIG. 1 , the tilt angle α is any value within the range of 30° to 50°, for example, the tilt angle α can be 30°, 40° or 50°, etc. Setting the tilt angle α within the range of 30° to 50° can ensure the support stability between the protruding structure 400 and the second surface 222, and can also make the gas flowing through the contact gap 301 between adjacent first protrusions 410 have a better flow rate, so as to ensure the volatilization speed of the water infiltrated into the abutting area 300.

[0052] In an example of the tailgate threshold structure of the present invention, along the width direction of the tailgate sheet metal body 100, the first surface 101 is an inclined structure that gradually approaches the horizontal ground from the side close to the rear of the vehicle to the side away from the rear of the vehicle (such as Figure 7As shown). The inclination angle β of the first surface 101 relative to the horizontal ground is any value in the range of 5 to 15°, for example, it can be 5°, 10° or 15°, etc. Preferably, the inclination angle β of the first surface 101 relative to the horizontal ground is 15°. This can facilitate the stamping of the first surface 101 and ensure that the tailgate sheet metal body 100 has better supporting strength. In this embodiment, by setting the first surface 101 to be inclined relative to the horizontal ground, the abutment area 300 formed between the first surface 101 and the second surface 222 can also be inclined. In this way, when water droplets penetrate into the abutment area 300, under the action of gravity, the water droplets can slowly flow to the outside of the abutment area 300 along the inclined abutment area 300, thereby alleviating the water accumulation phenomenon inside the abutment area 300 and reducing the probability of rust at the abutment area 300.

[0053] It should be noted that the tailgate threshold structure in the above embodiment may further include a tailgate threshold trim plate 500, which is snap-fitted and installed on the tailgate sheet metal body 100, and a receiving cavity is formed between the tailgate threshold trim plate 500 and the tailgate sheet metal body 100, and the tailgate sheet metal body 100 and the mounting plate 220 are both located in the receiving cavity, and the lock ring 210 on the lock ring seat 200 partially extends to the outside of the receiving cavity to be snap-fitted and connected with the lock body on the automobile tailgate 600. The specific structure of the tailgate threshold trim plate 500 snap-fitted and installed on the tailgate sheet metal body 100 can refer to the connection structure between the tailgate threshold and the tailgate threshold trim plate in the existing automobile structure, and will not be repeated here.

[0054] The utility model also provides a vehicle, which includes a vehicle body, a tailgate 600 and a tailgate threshold structure in any of the above examples. The vehicle body includes a vehicle body 700, the tailgate threshold structure is installed on the vehicle body 700, and the vehicle tailgate 600 is hingedly connected to the vehicle body 700. The vehicle tailgate 600 is installed with a lock body 601 that cooperates with the lock ring 210 on the lock ring seat body 200. When the vehicle tailgate 600 is closed, the lock ring seat body 200 cooperates with the lock body 601 installed on the vehicle tailgate 600 to achieve the locking between the vehicle tailgate 600 and the vehicle body 700.

[0055] The tailgate threshold structure provided by the utility model is provided with a first surface on the tailgate sheet metal body, and a second surface on the lock ring seat body, and the first surface and the second surface are in contact and form an abutment area, so that the support connection of the lock ring seat body on the tailgate sheet metal body can be realized through the contact between the first surface and the second surface. At the same time, since the abutment area is provided with a contact gap running through the abutment area, the contact gap can form an airflow channel inside the abutment area, accelerate the circulation of the airflow at the abutment area position, promote the volatilization of residual moisture at the abutment area position, reduce the probability of water accumulation in the abutment area, and then reduce the probability of rust at the connection position between the tailgate sheet metal body and the lock ring seat body, thereby correspondingly improving the installation strength of the lock ring and the stability of the automobile tailgate lock. Therefore, the utility model effectively overcomes some practical problems in the prior art and has a high utilization value and use significance. The above embodiments only illustrate the principle and effect of the utility model, and are not used to limit the utility model. Anyone familiar with this technology can modify or change the above embodiments without violating the spirit and scope of the utility model. Therefore, all equivalent modifications or changes made by those having ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
