[0039] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It will be understood that the specific embodiments described herein are only used to explain the related application, rather than to limit the application. The described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.
[0040] Pickup trucks are not only used for hauling goods, but also increasingly used as family cars in daily life. There are two types of pickup trucks with integrated cargo compartments: one is that the cargo compartment and the second row passenger compartment are completely separated by a rear panel; the other is that the rear panel is designed to be openable and connected to the cargo compartment when opened. In the second type of openable rear panel structure, the rear panel door needs to be installed on the rear and side C-pillar parts of the vehicle body through hinges and locks, and sealed with sealing strips.
[0041] According to the traditional sheet metal body structure design, the body side C-pillar, floor, and roof need to be welded together many times, and the tolerances are accumulated many times, which makes it difficult to ensure the dimensional consistency of the door frame system used to install the rear door, affecting the matching with the door. In addition, because the rear door is only connected to the body through hinges and locks, the seat pulling condition places high demands on the body connection; when the rear door is open, the original rear panel connection and support are missing, which also has a great impact on the body torsional stiffness.
[0042] See also Figures 1 to 12 In order to achieve the above objectives, this application discloses the following technical solutions:
[0043] The present application provides a door frame system 1, comprising a composite material door frame 11, at least two connecting brackets 2, at least two first mounting structures 13 and at least two second mounting structures 14 integrated in the door frame 11, wherein the connecting bracket 2 is used to mount the door frame 11 on the side panel 2; the first mounting structure 13 is used to mount the rear door; and the second mounting structure 14 is used to mount the decorative part 4. Since the sheet metal door frame system 1 is eliminated in the present application and the composite material door frame 11 is used for processing, welding is not required, and the cumulative tolerance can be reduced, thereby improving the dimensional consistency of the door frame system 1.
[0044] It should be noted that the composite door frame 11 is made of a thermosetting material (SMC) with a glass fiber content of 40%.
[0045] In order to improve the torsional rigidity, in some examples, the door frame 11 is a ring structure. According to the layout position, the door frame 11 is divided into a relatively arranged transverse frame and a longitudinal frame, wherein one transverse frame corresponds to the ceiling, one transverse frame corresponds to the floor, and the two longitudinal frames correspond to the side panels 2 (C-pillar position) on both sides. The transverse frame and the longitudinal frame change with the shape of the vehicle body.
[0046] In some examples of the present application, the structure of the door frame 11 is specifically introduced. The door frame 11 includes an inner frame 111, a through rib 112 and an outer frame 113 which are annular and arranged in sequence from the inside to the outside. A connecting plate 114 is provided between the inner frame 111 and the through rib 112, and between the through rib 112 and the outer frame 113. The plate surface of the connecting plate 114 is perpendicular to the plate surface of the through rib 112.
[0047] The number of turns of the reinforcing bar 112 can be half a turn, one turn, two turns, etc., and the number of turns of the reinforcing bar 112 can be adjusted according to the position to be reinforced.
[0048] In order to further increase the torsional rigidity of the door frame 11 , the door frame 11 further includes at least two reinforcing ribs 115 , which connect the inner frame 111 and the through ribs 112 , and the through ribs 112 and the outer frame 113 , and the plate surface of the reinforcing ribs 115 is perpendicular to the plate surface of the connecting plate 114 .
[0049] In order to improve the sealing performance at the corresponding positions of the door frame 11 and the vehicle body, the outer wall of the outer frame 113 is provided with glass glue 15 to seal the door frame 11 and the side panel 2. In some other examples, the outer frame 113 can also be provided with a sealing gasket and other structures to seal the door frame 11 and the vehicle body to improve the air tightness of the entire vehicle.
[0050] The function of the connecting bracket 2 is to connect the door frame 11 with the corresponding part of the vehicle body. In the figure, the connecting bracket 2 mainly connects the door frame 11 with the side panel 2 (C-pillar). The connecting bracket 2 includes a connecting seat, one end of which is fitted with the door frame 11, and the connecting seat is connected to the nut embedded in the door frame 11 through a fastener; the other end of the connecting seat is fitted with the side panel 2, and the connecting seat and the side panel 2 are connected through a fastener, such as Figure 2 and Figure 3 shown.
[0051] The connection seat is connected to the embedded nut of the door frame 11 through a fastener. In some examples of the present application, the connection seat can be partially embedded in the door frame 11, and the other part can be connected to the corresponding position of the vehicle body.
[0052] The connection base is connected by pre-embedded nuts, and multiple nuts can be pre-embedded at the location where the connection base is set. The structure of the connection base can be adjusted according to needs to improve the connection strength between the door frame 11 and the vehicle body. Two mounting holes are provided at one end of the connection base opposite to the door frame 11, and two mounting holes are provided at one end of the connection base opposite to the side panel 2.
[0053] Furthermore, the two mounting holes close to the door frame 11 are located on both sides of the two mounting holes close to the side panel 2 .
[0054] The connection seat is connected to the end face of the door frame 11, and the connection seat includes a first connection portion 121 and a second connection portion 122, and the first connection portion 121 and the second connection portion 122 are arranged at an angle. It should be noted here that the end face of the door frame 11 facing forward is the front end face, and the end face of the door frame 11 facing backward is the rear end face. The distance between the front end face and the rear end face corresponds to the thickness of the door frame 11.
[0055] The included angle between the side panel 2 and the end surface of the door frame 11 is the same as the included angle between the first connecting portion 121 and the second connecting portion 122 .
[0056] In order to reduce the difficulty of installation, in some examples of the present application, the door frame 11 further includes a positioning pin 16, and the positioning pin 16 is positioned and matched with the positioning hole of the side panel 2. In some other examples, a positioning hole is provided on the door frame 11, and a positioning pin 16 is provided at a corresponding position of the side panel 2. When the positioning pin 16 is matched with the positioning hole, the surface door frame 11 is installed in place, thereby reducing the difficulty of installing the door frame 11.
[0057] The first mounting structure 13 is used to mount the rear door. Since the rear door can be opened, the first mounting structure 13 can be used to mount the hinge and the lock body, wherein the hinge is used to realize the opening and closing of the rear door, and the lock body realizes the locking and unlocking of the rear door. The first mounting structure 13 includes a hinge mounting seat 131 and a lock body mounting seat 132. The hinge mounting seat 131 is used to mount the hinge and is connected to the nut embedded in the door frame 11 through a fastener; the lock body mounting seat 132 is used to mount the lock body and is connected to the nut embedded in the door frame 11 through a fastener. In this example, the hinge mounting seat 131 and the lock body mounting seat 132 are both connected to the embedded nut on the door frame 11. That is, the hinge mounting seat 131 is detachably connected to the door frame 11, and the lock body mounting seat 132 is detachably connected to the door frame 11. Therefore, when the hinge mounting seat 131 and the lock body mounting seat 132 are damaged, the hinge mounting seat 131 and the lock body mounting seat 132 are replaced with new ones.
[0058] In addition, the number of the embedded nuts for mounting the hinge mounting seat 131 and the lock body mounting seat 132 can be multiple, and the sizes of the hinge mounting seat 131 and the lock body mounting seat 132 can be adjusted according to actual needs. The hinge mounting seat 131 is mounted on the horizontal frame located below, and the lock body mounting seat 132 is mounted on the vertical frame.
[0059] There can be two hinge mounting seats 131, which are symmetrically mounted on the lower horizontal frame; there can be two lock body mounting seats 132, which are respectively mounted on one longitudinal frame, so as to improve the stability of the rear door under stress.
[0060] In some other examples, the hinge mounting seat 131 and the lock body mounting seat 132 are directly pre-buried in the door frame 11, which can further simplify the installation steps.
[0061] The second mounting structure 14 is used to mount the decorative element 4, which can be divided into an exterior 41 and an interior 42 according to the position, wherein the exterior 41 is located outside the vehicle and the interior 42 is located inside the vehicle. Correspondingly, the second mounting structure 14 includes an exterior bracket 141 and an interior bracket 142, wherein the exterior bracket 141 is used to mount the exterior 41 and is connected to a nut embedded in the door frame 11 through a fastener, and the interior bracket 142 is used to mount the interior 42 and is connected to a nut embedded in the door frame 11 through a fastener.
[0062] The above-mentioned exterior bracket 141 and interior bracket 142 can both be detachably connected to the door frame 11 through embedded nuts. In the present application, the exterior bracket 141 and the interior bracket 142 can also be directly pre-buried in the door frame 11 to simplify the installation difficulty.
[0063] Compared with the sheet metal door frame system 1, the door frame system 1 of the present application has the following advantages:
[0064] The high degree of integration can save time for factory welding and assembly.
[0065] The ring-shaped frame structure can improve torsional rigidity and is also helpful for side collision safety.
[0066] The glass glue 15 is used to achieve bonding and sealing with the vehicle body, which helps to improve the air tightness of the entire vehicle.
[0067] The embedded nut design meets the sealing requirements while ensuring the size, position and torque requirements.
[0068] Frame structures are lighter and less expensive than sheet metal structures under the same conditions.
[0069] See also Figures 9 to 12 The present application also discloses a vehicle body, including a side panel 2, a rear door, a decorative member 4 and a door frame system 1 as described above, wherein the door frame system 1 is mounted on the side panel 2 through a connecting bracket 2, the rear door is mounted on a first mounting structure 13 of the door frame system 1, and the decorative member 4 is mounted on a second mounting structure 14 of the door frame system 1. Since the door frame system 1 has the above beneficial effects, the vehicle body including the door frame system 1 has corresponding effects, which will not be described in detail here.
[0070] It should be noted that the rear door has an open state and a closed state, wherein Fig. 9 and Fig.10 The rear door is closed. Fig.11 and Fig.12 The rear door is open.
[0071] The present application also discloses a vehicle, including the vehicle body as described above. Since the vehicle body has the above effects, a vehicle including the vehicle body has corresponding effects, which will not be described in detail here.
