Description

Technical Field

[0001] The invention belongs to the technical field of automobiles, and in particular relates to a universal automobile hatch structure, a replacement method and an automobile. Background Art

[0002] In recent years, the automotive industry has experienced rapid growth, and consumers have placed higher demands on the quality and user experience of tangible automotive components. With the increasing popularity of new energy vehicles, the frequency of use of charging port covers has increased significantly, and the convenience and intelligent experience of their opening method have become important evaluation indicators. Currently, there are three main types of opening methods for automotive cover openings on the market: the first is the traditional opening method, which is triggered by a pull cord or pressed to pop up and requires manual opening; the second is the damped automatic opening method, which automatically pops up to the maximum opening after pressing and requires manual closing; and the third is the intelligent opening method, which supports button control, mobile phone app, or Bluetooth remote control.

[0003] However, existing automobile hoods generally only have a single opening form. Since different opening forms correspond to differentiated structural designs, it is difficult to universalize the early mold development, and the later structural modification requires high costs, making it difficult for the hood to achieve differentiated design for high-end and low-end products. As a result, a car model is only equipped with a hood with a single opening form from beginning to end, which cannot meet diverse market demands. Summary of the Invention

[0004] In order to solve the problems in the background technology, the present invention provides a universal automobile hatch structure, a replacement method and an automobile.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A universal automobile hatch structure comprises a hatch outer plate and a hinge hatch box assembly; The hinged mouth box assembly includes a hinge body and a mouth box body; The cover outer plate is mounted on the surface of the hinge body; The hinge body and the mouth box body are adapted to several different hinge assemblies, and any one of the hinge assemblies is used to realize the hinge connection between the hinge body and the mouth box body.

[0009] Preferably, after the hinge body and the mouth box body are hinged closed, the damping spring is in a contracted state.

[0010] Preferably, at least one of the hinge components comprises an O-ring, a torque pin and a torque spring; The torque pin passes through the matched first hinge part and the second hinge part from one side of the second mounting bracket, and the torque pin is clamped with the first hinge part; The torque pin is located at one end of the second mounting bracket and is provided with a transfer crank; The torsion spring is provided with swing arms on both sides, one of the swing arms is inserted into the adapter crank, and the other swing arm is inserted into the second mounting frame; The O-ring is installed in the annular groove on the surface of the torque pin.

[0014] A car is equipped with the universal car hatch structure.

[0015] Beneficial effects of the present invention: 1. The hinge body and the mouth box body of the present invention adopt a universal design, which can be adapted to a variety of hinge components.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0021] like Figure 1 The figure shows a universal automobile hatch structure, which includes a hatch outer panel 1 and a hinged hatch box assembly 2. The hinged hatch box assembly 2 is generally installed at the fuel tank port of a traditional automobile or the charging port of a new energy vehicle. The hinged hatch box assembly 2 can be designed as a universal product to adapt to different hinge components.

[0022] Combine Figure 4 or Figure 5 As can be seen, the hinged mouth box assembly 2 mainly consists of a hinge body 201 and a mouth box body 202, wherein the hinge body 201 is mounted on the surface of the mouth cover outer panel 1, and the surface of the mouth cover outer panel 1 can be painted and designed as required. The hinge body 201 and the mouth box body 202 are adapted to a number of different hinge components, any of which can achieve the hinge connection between the hinge body 201 and the mouth box body 202. The purpose of this design is that for manufacturers, the hinge body 201 and the mouth box body 202 can become a universal structure. If the hinge component needs to be switched or upgraded, a new hinge component can be directly replaced without modifying the hinge body 201 and the mouth box body 202. In addition, it can quickly realize the switching of multiple mouth cover structures (the mouth cover opening form is also different) to adapt to the high and low configuration differences of vehicle models.

[0023] like Figure 2As shown, to achieve a universal structure, the hinge body 201 includes a hinge plate 2011, a first hinge portion 2012 integrally connected to one end of the hinge plate 2011, and a locking insert 2013, while the flap outer plate 1 is mounted on the surface of the hinge plate 2011. The locking insert 2013 is mounted on the surface of the hinge plate 2011 facing the flap box body 202, and is located at the edge of the hinge plate 2011 and away from the first hinge portion.

[0024] like Figure 3 As shown, in order to use a universal structure, the mouth box body 202 includes a mouth box 2021 and a second hinged portion 2022 integrally connected to one end of the mouth box 2021. The upper end of the second hinged portion 2022 is provided with a first mounting bracket 2023, and the lower end is provided with a second mounting bracket 2024. The two mounting brackets are respectively adapted to different hinge components. Therefore, during installation, depending on the different hinge components, part of the hinge components can be installed from the first mounting bracket 2023, and the other part of the hinge components can be installed from the second mounting bracket 2024. Therefore, Figure 2 and Figure 3 The structure in the embodiment can be adapted to at least two hinge components, and the second hinge portion 2022 and the first hinge portion 2012 can be hinged by two different hinge components.

[0025] Furthermore, a matching hole 2025 is opened in the mouth box 2021 at the position corresponding to the self-locking plug-in 2013, and an actuator 203 is installed on the side of the mouth box 2021 facing away from the hinge plate 2011, and the actuator 203 is located at the opening of the matching hole 2025; when the hinge body 201 and the mouth box body 202 are closed, the self-locking plug-in 2013 is inserted in the actuator 203.

[0026] The following is based on Figure 2 The hinge body 201 and Figure 3 The mouth box body 203 introduces two adapted hinge components.

[0027] like Figure 4The figure shows an exploded view of the first hinge assembly, hinge body 201, and mouth box body 203. The first hinge assembly comprises a damping spring 204, a damping pin 205, an O-ring 206, and a damper 207. During installation, the O-ring 206 fits within an annular groove on the surface of the damping pin 205, located near the end of the damping pin 205. The damping pin 205 passes from the underside of the second mounting bracket 2024 through the mating first hinge portion 2012 and second hinge portion 2022. In addition, the damping pin 205 has an anti-dropping structure and a slot, so the damping pin 205 can be snapped onto the first hinge part 2012 of the hinge body 201. This can prevent the damping pin 205 from falling off later and allow the hinge body 201 to rotate together with the damping pin 205. The O-ring 206 is compressed between the damping pin 205 and the hinge body 201, thereby improving the sealing effect of the damping pin 205 and the first hinge part 2012.

[0028] It should be noted that the installation position of the damper 207 needs to be designed in advance so that another hinge assembly can be installed on the side where the damper 207 is installed, and no mold changes are involved later, thus realizing two forms of opening the lid.

[0029] Combine Figure 5 It can be seen that the damping spring 204 is fixedly sleeved on one end of the damping pin 205, and the damping spring 204 is provided with a swing arm, which is inserted into the first mounting bracket 2023, and the damper 207 is installed on the other end of the damping pin 205.

[0030] It should be noted that after the hinge body 201 and the mouth box body 202 are hinged and closed, the damping spring 204 is in a contracted state, so that the hinge body 201 can be automatically opened by pressing the mouth cover outer plate 1.

[0031] Furthermore, after the first hinge assembly, the hinge body 201 and the mouth box body 202 are matched, the working process is as follows: When the hinge body 201 needs to be opened (for example, for refueling or charging), the user presses the outer panel 1 of the flap, and the hinge body 201 is subjected to force together with the outer panel 1 of the flap. At this time, the actuator 203 pushes the hinge body 201 out. Since the damping spring 204 is in a compressed state, it can release a large torque, so that the hinge body 201 is directly opened to the maximum position. During the opening process, the damping 207 can reduce the impact, so that the hinge body 201 slowly opens, and then the hinge body 201 can be manually closed.

[0032] like Figure 6The figure shows an exploded view of the second hinge assembly, hinge body 201, and mouth box body 201. This second hinge assembly includes an O-ring 206, a torque pin 208, and a torque spring 209. The torque pin 208 passes through the mating first hinge portion 2012 and second hinge portion 2022 from the underside of the second mounting bracket 2024. The torque pin 208 has a built-in anti-dropout structure and a slot that allows it to be locked onto the hinge body 201. This prevents the torque pin 208 from falling off later and allows the hinge body 201 to rotate with the traditional pin 208.

[0033] In addition, combined Figure 7 As can be seen, a transfer crank 2081 is provided at one end of the torque pin 208 located on the second mounting bracket 2024. Furthermore, swing arms are provided on both sides of the torque spring 209, one of which is inserted into the transfer crank 2081, and the other into the second mounting bracket 2024. An O-ring 206 is fitted within an annular groove on the surface of the torque pin 208, located near the end of the torque pin 206. Furthermore, the O-ring 206 is compressed between the torque pin 208 and the hinge body 201, enhancing the sealing effect.

[0034] It should be noted that the equilibrium angle of the torque spring 209 is 40-50°, preferably 45°, and the equilibrium angle is the angle between the hinge plate and the mouth box 2021 .

[0035] Furthermore, after the second hinge assembly, the hinge body 201 and the mouth box body 202 are matched, the working process is as follows: When the hinge body 201 needs to be opened (for example, to refuel or charge), the user presses the cover outer panel 1. The hinge body 201 is then subjected to force along with the cover outer panel 1. The actuator 203 then pushes the hinge body 201 out, causing it to pop open approximately 10mm. The hinge body 201 is then manually opened to approximately 45° (at the equilibrium angle of the torque spring 209). The torque spring 209 then pulls the hinge body 201 to its maximum position. To reclose the hinge body 201, the hinge body 201 is manually closed to approximately 45°. The torque spring 209 then pulls the hinge body 201 back to the initial 10mm pop-out position. Finally, the cover outer panel 1 is manually pressed, causing the actuator 203 to re-lock the self-locking plug 2013.

[0036] It should be noted that a transfer crank 2081 is provided at the end of the second group of hinge components, and the swing arm of the torque spring 209 will move with the transfer crank 2081. When the hinge body 201 is opened, the torque spring 209 will be compressed during the process of manually opening the hinge body 201 to 45° (this angle is not limited to 45°, it is directly related to the size of the swing arm box and the transfer crank 2081). At the same time, the connection point between the swing arm and the transfer crank 2081 is moved to the other side (the critical position moved to the other side corresponds to the position where the hinge body 201 is opened to 45°), so that the hinge body 201 can be opened when the torque spring 209 rebounds. Later, the torque spring 209 rebounds and the hinge body 201 can be opened to the maximum position.

[0037] like Figure 8 As shown, an alternative method is used Figure 1-Figure 7 A universal automobile hatch structure includes the following steps: S1: Obtain the hinge assembly installed on the hinge body 201 and the mouth box body 202 of the automobile and use it as the hinge assembly to be replaced.

[0038] S2: Obtain the types of hinge components that are compatible with the hinge body 201 and the mouth box body 202, and select one of the hinge components as a target hinge component.

[0039] S3: Replace the articulated component to be switched with the target articulated component.

[0040] Combine Figure 4 and Figure 6 It can be seen that the two hinge components can be replaced. During this process, the hinge body 201 and the mouth box body 202 remain unchanged, so as to quickly switch between the two opening modes to adapt to the high and low configuration differences of the vehicle models.

[0041] A car equipped with Figure 1-Figure 7 A universal automobile hatch structure is provided. After using the hatch structure, the configuration of the hatch structure can be changed according to demand to meet different customer needs.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
