DETAILED DESCRIPTION

[0032] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0033] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0034] In order to save space inside the vehicle, off-road vehicles often mount spare tires on the side-opening tailgate, so the tailgate structure has higher strength requirements. It is difficult to meet the rigidity requirements of mounting spare tires with all-plastic or aluminum sheet metal tailgates. Therefore, in related technologies, side-opening tailgates are usually steel sheet metal structures with high strength. With the increasing requirements for electrification, intelligence, lightweight and safety of off-road vehicles, more and more off-road vehicles need to arrange satellite positioning antennas and obstacle avoidance radars on the tailgate, but electromagnetic waves are difficult to penetrate metal materials. Therefore, the use of new materials and new technologies to replace traditional steel sheet metal tailgates has become an industry development trend in recent years.

[0035] In view of this, the present application provides a side-opening tailgate and a vehicle, the overall design concept is: a three-layer tailgate structure composed of metal and non-metal is adopted, the metal alloy skeleton of the middle layer meets the rigidity, the outer non-metal plate ensures the radar antenna signal penetration, and the inner plate ensures the sealing surface accuracy. The content of the present application will be described in detail below in conjunction with the drawings and embodiments.

[0036] For the convenience of description, the various directions involved in the embodiments are defined as follows: In the field of vehicle technology, the length direction of the vehicle is usually called the X direction or longitudinal direction, the width direction of the vehicle is called the Y direction or transverse direction, and the height direction of the vehicle is called the Z direction or vertical direction. The side-opening tailgate is installed at the rear end of the vehicle, and the width direction of the side-opening tailgate is also the width direction of the vehicle, that is, the Y direction; the height direction of the side-opening tailgate is also the height direction of the vehicle, that is, the Z direction; the thickness direction of the side-opening tailgate is also the length direction of the vehicle, that is, the X direction. The interpretation of the relevant direction expressions in the following embodiments can refer to the above content.

[0037] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In the first embodiment of the present application, there is provided a side-opening tailgate 100, including a door body 110 and an electromagnetic wave transmitting and receiving device (not shown in the figure) installed on the door body 110. The door body 110 is a three-layer structure, including a tailgate outer panel 111, a metal frame 113 and a tailgate inner panel 112 connected in sequence. The middle metal frame 113 is made of metal material to meet the rigidity requirements of the tailgate. The tailgate outer panel 111 is made of non-metallic material and is light in weight. The electromagnetic wave transmitting and receiving device is installed on the inner side of the tailgate outer panel 111. The electromagnetic wave transmitting and receiving device can be at least one of an antenna and a radar. The electromagnetic wave transmitting and receiving device can be used to locate and / or identify obstacles. The electromagnetic wave signal can pass through the non-metallic tailgate outer panel 111 without being shielded by metal.

[0038] The electromagnetic wave transmitting and receiving device is encapsulated inside the door body 110. To ensure that the electromagnetic wave transmitting and receiving device has sufficient installation space, please refer to Figure 5 and Figure 6 In some embodiments, the inner side of the tailgate outer panel 111 is provided with an antenna installation hole 111g and a radar installation hole 111h, and the metal frame 113 is provided with an avoidance area 113a corresponding to the position of the radar and the satellite antenna. The avoidance area 113a can be a through opening provided on the metal frame 113 corresponding to the position of the radar and the satellite antenna, or can be an inwardly recessed groove. The main bodies of the radar (not shown in the figure) and the satellite antenna (not shown in the figure) are located in the avoidance area 113a, and do not occupy the thickness space of the side-opening tailgate 100.

[0039] See also Figure 2 , Figure 3and Figure 4 The side-opening tailgate 100 is usually provided with a sealing strip 120, a tailgate lock 130 and a hinge assembly 140. The sealing strip 120 is provided on the inner side of the door body 110, specifically the outer side of the tailgate inner plate 112, and is used to seal the gap between the door body 110 and the vehicle body. The tailgate lock 130 is located on the first side of the inner side of the door body 110, and is used to lock with the lock seat of the vehicle body. The tailgate lock 130 is connected to the metal frame 113 and is at least partially exposed to the outer side of the tailgate inner plate 112 to lock with the lock seat of the vehicle body. A handle is correspondingly provided on the outer side of the door body 110 to open the door lock, and the handle is installed and fixed through the handle mounting hole 111b provided on the tailgate outer plate 111. The hinge assembly 140 is located on the second side of the inner side of the door body 110, and is used to hinge the door body 110 with the vehicle body. The hinge assembly 140 is also connected to the metal frame 113 and is at least partially exposed to the tailgate inner plate 112. For ease of understanding, the first side is defined as the left side of the side-opening tailgate 100, and the second side is defined as the right side of the side-opening tailgate 100. The first side hereinafter is equivalent to the left side, and the second side is equivalent to the right side. Of course, in other embodiments, the right side of the side-opening tailgate 100 is also defined as the first side, and the left side of the side-opening tailgate 100 is defined as the second side.

[0040] See also Figure 3 In some embodiments, the side-opening tailgate 100 is further provided with a stopper 190, and the vehicle body is provided with a stopper groove matched with the stopper 190. The stopper 190 is located below the tailgate lock 130, and the stopper structure 190 and the door lock 130 are located in the area surrounded by the sealing strip 120. After the tailgate lock 130 is locked, the stopper 190 extends into the stopper groove and snaps into place, which plays a role in preventing the tailgate from sinking in the Z direction and preventing the tailgate from rotating backward in the X direction.

[0041] To improve the space utilization rate inside the door body 110, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 In some embodiments, the installation positions of the radar and the satellite antenna are respectively close to the hinge assembly 140 and the tailgate lock 130, and the area of ​​the avoidance zone 113a close to the tailgate lock 130 can be expanded, so that the door lock driving device 170 used to drive the tailgate lock 130 is also arranged in the avoidance zone 113a. In some embodiments, the door lock driving device 170 is located in the avoidance zone 113a far away from the tailgate lock 130, so that the bending curvature radius of the pull wire 171 used to drive the tailgate lock 130 is larger, so as to avoid excessive bending of the pull wire 171.

[0042] The material of the tailgate outer panel 111 can be non-metallic materials such as plastic and PCM composite materials. Considering that the tailgate outer panel 111 does not bear any load and serves as an exterior surface, the tailgate outer panel 111 is required to have good styling. In some embodiments, the tailgate outer panel 111 is a plastic part that is integrally formed by injection molding. The plastic outer panel can allow electromagnetic waves to penetrate, and can realize the function of arranging satellite antennas and obstacle avoidance radars inside the tailgate.

[0043] The tailgate inner panel 112 is mainly used to provide a sealing surface 112c for the installation of the sealing strip 120. The surface quality requirements are relatively high. The tailgate inner panel 112 can be made of stamped metal sheet metal or non-metallic materials such as plastic and PCM composite materials. Considering weight reduction and easy modeling, in some embodiments, the tailgate inner panel 112 is also a plastic part. Through injection molding, the tailgate outer panel 111 and the tailgate inner panel 112 can use the same injection molding material. The plastic inner panel shields the metal frame 113 inside the tailgate, improving the appearance quality after the tailgate is opened. In addition, the sealing strip 120 directly contacts the smooth plastic surface, which solves the problem of rough sealing surface and poor precision of the metal frame 113.

[0044] The metal skeleton 113 is used as a bearing member and reinforcement member of the side-opening tailgate 100, and is required to have sufficient rigidity and structural strength. Its material can be steel or aluminum alloy, and the molding process can be casting or stamping. Taking weight reduction into consideration, in some embodiments, the metal skeleton 113 is a die-cast aluminum-magnesium alloy part. Compared with the sheet metal reinforcements used in conventional tailgates, die-cast aluminum alloy parts have higher strength, lower cost, better recyclability, and greater load-bearing capacity, and are more suitable for off-road vehicles that need to carry a spare tire 161. In addition, once a fire occurs, aluminum alloy has a higher melting point and better flame retardancy, which can improve the safety of the vehicle.

[0045] See also Figure 5 The shape of the metal frame 113 is adapted to the door body 110, and a window frame reinforcement structure is formed at the tailgate window 110a. The door lock installation, hinge installation, and spare tire 161 installation also have a solid structure, and the thickness of the solid structure at the door lock installation, hinge installation, and spare tire 161 installation is greater than the thickness of the window frame reinforcement structure. The metal frame 113 is a frame structure as a whole, and the surface is densely covered with grooves. The grooves can significantly reduce the weight of the metal frame 113, and on the other hand, they can also absorb vibration energy.

[0046] To ensure the integrity of the exterior, please refer to Figure 7In some embodiments, the tailgate outer panel 111 and the tailgate inner panel 112 are bonded by structural adhesive, and the two enclose a space for accommodating the metal frame 113. The tailgate outer panel 111 and the metal frame 113 are bonded by sealant, one side of the metal frame 113 abuts against the tailgate outer panel 111, and sealant is applied at the abutment. Compared with structural adhesive, the metal frame 113 and the tailgate outer panel 111 are easier to disassemble and separate after the sealant is bonded. The metal frame 113 and the tailgate inner panel 112 are connected by fasteners. The metal frame 113 and the external non-metallic parts adopt a connection scheme of fastener connection + bonding. After a collision or scratch occurs, if there is no damage to the internal metal frame 113 structure, the plastic outer panel and / or plastic inner panel can be replaced separately, reducing the maintenance cost.

[0047] See also Figure 5 and Figure 6 In some embodiments, the tailgate inner plate 112 is a closed annular structure, and is provided with a sealing surface 112c for installing the sealing strip 120, and an appearance surface where the hinge assembly 140 and the tailgate lock 130 are located. To cover other parts of the metal frame 113, please refer to Figure 4 In some embodiments, the side-opening tailgate 100 further includes an interior panel 114, which is covered on the tailgate inner panel 112 and covers the inner ring opening 112a of the tailgate inner panel 112. The interior panel 114 is detachably connected to the metal frame 113 through a snap 1131 and / or a fastener. After the tailgate inner panel 112 is installed, the electromagnetic wave transmitting and receiving devices such as radar and antenna are still exposed to the outside through the inner ring opening 112a. When maintenance or disassembly and replacement is required, the interior panel 114 can be removed, and maintenance personnel can directly operate through the inner ring opening 112a.

[0048] In the related art, the side-opening tailgate 100 usually first meets the equipment requirements of the spare tire assembly 160. All tailgate locks 130 and hinges are arranged around the space for the spare tire assembly 160. The sealing strip 120 and the tailgate lock 130 are arranged side by side in the thickness direction of the tailgate, and in the width direction of the tailgate, the sealing strip 120 and the tailgate lock 130 completely overlap. The tailgate lock 130, the limit block 190 and the handle completely occupy the left space, leaving no space for arranging the taillights. The right hinge will occupy an upper position. In order to arrange the spare tire assembly 160 in the best position, a right eccentric arrangement is adopted, which will place the spare tire assembly 160 to the right, close to the hinge side. There is no space for arranging the taillights on the right side of the spare tire assembly 160. As an important appearance and functional part, the taillights are required to be symmetrical on both sides and cannot be blocked by the spare tire assembly 160. Due to space limitations, the side-opening tailgate 100 in the related art cannot be equipped with taillights, and all taillight functions can only be placed completely on the body, specifically on both sides of the opening of the luggage compartment at the rear end of the body. The installation structure of the taillights increases the complexity of the body-in-white structure. In addition, the side-opening tailgate 100 mainly meets off-road requirements, and hanging the spare tire assembly 160 is an important functional requirement. If the taillights are forcibly arranged on the side-opening tailgate 100, the strength of the tailgate will be greatly reduced, which will lead to insufficient tailgate performance during off-road driving (such as vibration, abnormal noise, and deformation of the tailgate).

[0049] To solve the above problems, in some embodiments of the present application, a taillight is integrated into the side-opening tailgate 100. Figure 1 , Figure 2 and Figure 3 The side-opening tailgate 100 further includes a first taillight 151 and a second taillight 152 respectively arranged on both sides of the tailgate outer panel 111. Taillight mounting holes 111c are respectively arranged on both sides of the tailgate outer panel 111 for mounting the two taillights. In the thickness direction of the door body 110, the first taillight 151 and the tailgate lock 130 are arranged side by side; in the height direction of the door body 110, the height of the second taillight 152 is the same as that of the first taillight 151, and both are less than the height of the hinge located at the top of the hinge assembly 140.

[0050] See also Figure 2 and Figure 3, which is different from the conventional side-opening tailgate 100 in which the sealing strip 120 is arranged on the tailgate lock 130, in the present application, the tailgate lock 130 is located in the area surrounded by the sealing strip 120, that is, the tailgate lock 130 and the sealing strip 120 are staggered in the width direction of the door body 110. By improving the side-by-side arrangement of the tailgate lock 130 and the sealing strip 120 along the X direction to side-by-side arrangement along the Y direction, the space occupied by the tailgate lock 130 and the sealing strip 120 in the thickness direction of the door body 110 can be reduced, so that the tailgate lock 130 and the sealing strip 120 are used to avoid the space for arranging the first taillight 151 in the thickness direction of the door body 110. The first taillight 151 is arranged on the first side of the outer side surface of the door body 110, and the first taillight 151 and the tailgate lock 130 are arranged side by side in the thickness direction of the door body 110 without overlapping, and the first taillight 151 and the tailgate lock 130 do not interfere with each other. In an embodiment where the side-opening tailgate 100 further includes a limit block 190 , the limit block 190 is disposed below the tailgate lock 130 , and both the limit block 190 and the tailgate lock 130 are located within the area surrounded by the sealing strip 120 .

[0051] See also Figure 2 and Figure 3 In some embodiments, in order to further optimize the arrangement of the first taillight 151, the sealing strip 120 and the tailgate lock 130, along the thickness direction of the door body 110, the sealing strip 120 overlaps with the tailgate lock 130, and the sealing strip 120 does not exceed the position of the tailgate lock 130, that is, the sealing strip 120 is completely located in the extension space of the tailgate lock 130 in the X direction, and the sealing strip 120 does not occupy the thickness space of the door body 110. Along the width direction of the door body 110, the sealing strip 120 and the tailgate lock 130 are arranged side by side, and both overlap with the first taillight 151 at least partially, which is equivalent to that the sealing strip 120 and the tailgate lock 130 are both located in front of the first taillight 151, and the first taillight 151 does not occupy additional space in the Y direction, and does not affect the arrangement of the spare tire assembly 160.

[0052] By arranging the sealing strip 120 and the tailgate lock 130 side by side in the Y direction and the tailgate lock 130 being located in the area surrounded by the sealing strip 120, not only is installation space provided for the first taillight 151, but also the size of the opening of the luggage compartment is not affected (the opening of the luggage compartment is the size in the middle of the sealing strip 120). The opening of the luggage compartment is as large as possible, which can be convenient for placing luggage. For a side-opening tailgate 100 of the same size, the present application arranges the tailgate lock 130 in the area surrounded by the sealing strip 120, which not only solves the arrangement problem of the first taillight 151, but also increases the opening size of the luggage compartment. In addition, the tailgate lock 130 is arranged in the dry area (the area surrounded by the sealing strip 120), which improves the sealing wading performance of the side-opening tailgate 100.

[0053] See also Figure 2 and Figure 4In the present application, the height of the hinge at the top of the hinge assembly 140 is higher than that of the conventional side-opening tailgate 100, and is higher than the height of the second taillight 152, so that the second taillight 152 and the hinge at the top of the hinge assembly 140 are staggered in the Z direction, solving the problem of arranging the hinge side taillight space. The height of the second taillight 152 is the same as that of the first taillight 151, meeting the appearance requirements.

[0054] It should be noted that the second taillight 152 and the hinge located at the top of the hinge assembly 140 are staggered in the Z direction, which means that the second taillight 152 and the hinge located at the top of the hinge assembly 140 are not completely overlapped in the Z direction, that is, the overall height of the hinge located at the top of the hinge assembly 140 is higher than the second taillight 152. The specific expression may be that the height of the upper side of the hinge located at the top of the hinge assembly 140 is higher than the height of the upper side of the second taillight 152, and the height of the lower side is higher than the height of the lower side of the second taillight 152, that is, the second taillight 152 and the hinge located at the top of the hinge assembly 140 are arranged side by side in the Z direction and partially overlap; the specific expression may also be that the height of the lower side of the hinge located at the top of the hinge assembly 140 is higher than the height of the upper side of the second taillight 152, that is, the second taillight 152 and the hinge located at the top of the hinge assembly 140 are arranged side by side in the Z direction and do not overlap.

[0055] In the design stage, the position of the taillight is first determined according to the styling effect, and then the position of the sealing strip 120, the tailgate lock 130, and the position of the hinge at the top of the hinge assembly 140 are determined according to the position of the taillight. In order to stably support the door body 110, the hinge assembly 140 usually includes at least two hinges. Figure 2 and Figure 4 The specific structure and distribution of the hinge assembly 140 in some embodiments are shown. Figure 2 The hinge assembly 140 includes an upper hinge 141 and a lower hinge 142 spaced apart along the height direction of the door body 110, and the height of the second taillight 152 is smaller than the upper hinge 141 and larger than the lower hinge 142. In other embodiments, if the overall height of the side-opening tailgate 100 is larger, the hinge assembly 140 may include 3 or 4 hinges.

[0056] In some embodiments, the side-opening tailgate 100 further includes at least one of a spoiler (not shown in the figure), a support rod assembly 181, a spare tire assembly 160, and an exhaust box (not shown in the figure). The above accessories can be optionally configured for vehicles of different configuration levels and different uses.

[0057] If a spoiler is selected, the spoiler is installed on the top of the tailgate outer panel 111. The upper edge of the window frame of the tailgate outer panel 111 is provided with some spoiler installation holes 111f and / or buckles, such as Figure 8As shown, the spoiler is connected to the tailgate outer panel 111 via fasteners and / or buckles, which helps improve the vehicle's grip and stability during driving.

[0058] If the support rod assembly 181 is selected, one end of the support rod assembly 181 is connected to the metal frame 113 through a fastener, and the other end is connected to the vehicle body. The support rod assembly 181 is located at the lower edge of the door body 110 and close to the side where the hinge assembly 140 is located. The two ends of the support rod assembly 181 form two joints with the door body 110 and the vehicle body respectively, so that the support rod assembly 181 can rotate relative to the door body 110 and the vehicle body according to the opening angle of the door. The function of the support rod assembly 181 is to support the door body 110 and its accessories to prevent the door body 110 from sinking. Please refer to Figure 4 and Figure 5 In some embodiments, the support rod assembly 181 includes a support rod 181 and two support rod brackets 182 for mounting the support rod 181. The support rod 181 is a telescopic rod, and specifically can be an electric telescopic rod, a hydraulic support rod 181, or a gas pressure support rod 181. The two ends of the support rod 181 are respectively hinged to the two support rod brackets 182, and the two support rod brackets 182 are respectively connected to the door body 110 and the vehicle body through fasteners. The support rod bracket 182 connected to the door body 110 is located on the outer side of the tailgate inner plate 112. The tailgate inner plate 112 is provided with a first through hole 112b for the fastener of the support rod bracket 182 to pass through and connect with the metal frame 113.

[0059] If an exhaust box is selected, the exhaust box is installed in the middle of the tailgate outer panel 111 and corresponds to the position of the spare tire assembly 160. Figure 6 and Figure 8 In some embodiments, an exhaust box installation hole 111d is provided in the middle of the tailgate outer panel 111 to accommodate the exhaust box. In some embodiments, the exhaust box is located in the area surrounded by the second through holes 111a, and the exhaust box is placed in the inner space of the spare tire bracket 162 and the hollow area 113b of the metal frame 113. The exhaust box can balance the pressure difference between the inside and outside of the vehicle, and the problem of difficult door closing can be improved after the exhaust box is installed.

[0060] For the vehicle model with the optional spare tire assembly 160, the spare tire assembly 160 is also connected to the metal frame 113 by fasteners. Figure 2 and Figure 3 The spare tire assembly 160 includes a spare tire 161 and a spare tire bracket 162. The spare tire 161 is mounted on the spare tire bracket 162. The spare tire bracket 162 is connected to the door body 110 through a fastener. The tailgate outer panel 111 is provided with a second through hole 111a for the fastener to pass through. The spare tire bracket 162 is connected to the metal frame 113 through a fastener. Figure 5 In some embodiments, a hollow area 113b is provided in the middle of the metal frame 113, and the fasteners are connected to the side edges of the hollow area 113b.

[0061] In some embodiments, the side-opening tailgate 100 further includes three spare tire support blocks (not visible in the figure), and the spare tire support blocks are made of elastic material, such as rubber, silicone or spring. Figure 8 In some embodiments, three support block mounting holes 111e are correspondingly provided on the tailgate outer panel assembly 111 for the spare tire support block to extend outward, and the spare tire support block extends outward through the support block mounting holes 111e to form a triangular support structure. It is understandable that for a side-opening tailgate without a spare tire assembly 160, a spare tire support block may not be provided, and the corresponding support block mounting holes 111e are not required to be provided on the tailgate outer panel assembly 111. When the spare tire assembly 160 vibrates, the three elastic spare tire support blocks first reduce and filter the vibration energy of the spare tire assembly 160, and the remaining vibration energy is transmitted to the metal frame 113 through several mounting points of the spare tire bracket 162.

[0062] The transmission path of vibration energy in the metal frame 113 is as follows: Fig. 9 As shown by the arrow in the middle. Fig. 9 The force transmission principle of the metal frame 113 is as follows: when driving on a bad road, the spare tire assembly 160 drives the tailgate to vibrate up and down and left and right. The vibration of the spare tire assembly 160 is transmitted to the metal frame 113 by the spare tire bracket 172. The metal frame 113 fully reduces and absorbs the vibration energy and disperses the transmitted vibration. The vibration is transmitted to the tailgate lock 130 to the left and to the hinge assembly 140 to the right. It prevents vibration deformation from being transmitted to weak points (the upper edge and side edge of the window frame), thereby reducing the deformation risk at the weak points of the tailgate and improving road durability.

[0063] A second aspect embodiment of the present application provides a vehicle, comprising a vehicle body and a side-opening tailgate 100 of any embodiment of the first aspect above, a luggage compartment is provided at the rear of the vehicle body, the side-opening tailgate 100 is hinged to the vehicle body by a hinge assembly 140, and the opening of the luggage compartment is sealed by a sealing strip 120, and the vehicle body is provided with a lock seat that is locked with a tailgate lock 130 of the side-opening tailgate 100.

[0064] For the embodiment in which the side-opening tailgate 100 is provided with a limit block 190, the vehicle body is provided with a limit groove cooperating with the limit block 190. After the tailgate lock 130 is locked, the limit block 190 extends into the limit groove and snaps into place, thereby preventing the tailgate from sinking in the Z direction and rotating backward in the X direction.
