DETAILED DESCRIPTION

[0022] The application will be described in further detail below with reference to the drawings and embodiments. It is particularly pointed out that the following embodiments are only for illustrating the application, but do not limit the scope of the application. Similarly, the following embodiments are only part of the embodiments of the application, but not all the embodiments of the application. All other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0023] In this document, reference to“an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. Those skilled in the art will appreciate that embodiments described herein can be combined with other embodiments.

[0024] It should be noted that the terms“comprising” and“having” and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusion.

The first connecting member 100 can be fixed to the first surface 510 and engaged with the second connecting member 200 in the body groove 501. Furthermore, the second connecting member 200 can cooperate with the third connecting member 300 to be fixed to the roof beam 502 and / or the crossbeam 503.

[0030] Furthermore, please refer to the following: Figure 3 and Figure 4 , Figure 3 yes Figure 2 A three-dimensional structural diagram of the vehicle body component 10 in the embodiment. Figure 4 yes Figure 3A cross-sectional structure of the vehicle body assembly 10 along A-A is shown in the embodiment. Optionally, in the embodiment, the first connecting member 100 has a first fixing portion 101 and a first connecting portion 102 at two ends thereof, the second connecting member 200 has a second connecting portion 201 and a third connecting portion 202 at two ends thereof, and the third connecting member 300 has a second fixing portion 301 and a third fixing portion 302 at two ends thereof, and a fourth connecting portion 303 is formed between the second fixing portion 301 and the third fixing portion 302.

[0031] The first fixing portion 101 of the first connecting member 100 can be fixed to the first surface 510, and the first connecting portion 102 can be arranged in the vehicle body groove 501. The second connecting portion 201 of the second connecting member 200 is clamped with the first connecting portion 102 in the vehicle body groove 501, so that the second connecting member 200 is detachably fixed in the vehicle body groove 501, and the third connecting portion 202 is arranged on the side of the roof beam 502 away from the vehicle body groove 501. The second fixing portion 301 of the third connecting member 300 abuts against the third surface 530, the third fixing portion 302 abuts against the second surface 520, the fourth connecting portion 303 is connected to the third connecting portion 202, and the fourth connecting portion 303 and the third connecting portion 202 cooperate to fix the second fixing portion 301 on the vehicle cross beam 503 and / or fix the third fixing portion 302 on the roof beam 502.

[0032] Further, the connecting assembly 20 can further include a locking member 400, which can cooperate with the third connecting portion 202 and the fourth connecting portion 303 to fix the second fixing portion 301 on the third surface 530 and / or fix the third fixing portion 302 on the second surface 520. The fourth connecting portion 303 can be formed with a through hole, and the third connecting portion 202 can pass through the through hole, and then the third connecting portion 202 can be screwed to the locking member 400 arranged at the top of the fourth connecting portion 303, and then the locking member 400 can abut against the fourth connecting portion 303 in cooperation with the third connecting portion 202, so as to fix the second fixing portion 301 formed at the end of the fourth connecting portion 303 on the second surface 520 and / or fix the third fixing portion 302 formed at the end of the fourth connecting portion 303 on the third surface 530.

[0033] Specifically, in the present embodiment, the third connecting member 300 can be a bracket, the second and third fixed parts 301 and 302 can be two side walls of the bracket, and the fourth connecting part 303 can be a top wall formed between the two side walls and connected to the two side walls respectively. The top wall can be formed with a through hole capable of accommodating the third connecting part 202. The third connecting part 202 can be a screw rod, and the locking member 400 can be a bolt corresponding to the third connecting part 202. When the third connecting part 202 penetrates through the fourth connecting part 303, the locking member 400 can be threadedly connected with the third connecting part 202 and abut against the fourth connecting part 303. As the locking member 400 is gradually screwed into the third connecting part 202, the locking member 400 can apply a force to the third connecting part 202 away from the vehicle body groove 501, so as to further fix the second connecting part 201 to the first connecting part 102. At the same time, the locking member 400 can correspondingly apply a force to the fourth connecting part 303 towards the vehicle body groove 501, so as to correspondingly abut the second fixed part 301 against the third surface 530 and / or correspondingly abut the third fixed part 302 against the second surface 520. Thus, the third connecting member 300 can be fixed to the roof beam 502 and the cross beam 503.

[0034] It should be noted that the locking member 400 is used to connect between the second connecting member 200 and the third connecting member 300 in the present embodiment, so as to apply opposite forces to the second connecting member 200 and the third connecting member 300 respectively, to reinforce the connection structure of the vehicle body assembly 10. It can be understood that in other embodiments of the present application, the locking member 400 can also be other elements capable of cooperating with the second connecting member 200 and the third connecting member 300 to realize corresponding functions. For example, the locking member 400 can be an element capable of being clamped with the second connecting member 200 and capable of limiting the movement of the second connecting member 200 towards the vehicle body groove 501 by using the clamping structure. Thus, when the second connecting member 200 is clamped with the locking member 400 under the action of an external force, the vehicle body can also form a stable connection structure by cooperating with the second connecting member 200, the third connecting member 300 and the locking member 400. The present embodiment is only an example and is not specifically limited in the embodiments of the present application.

[0035] In addition, the first fixed part 101 is fixed on the first surface 510, and the first fixed part 101 and the first connecting part 102 can form a first preset angle a, so that the first connecting part 102 is arranged in the vehicle body groove 501, and the second connecting part 201 and the third connecting part 203 can form a second preset angle β, so that the first connecting part 102 can be clamped in the vehicle body groove 501, and the second connecting part 200 can be inserted into the vehicle body groove 501 from the gap between the roof beam 502 and the vehicle body groove 501 and clamped on the first connecting part 100 fixed on the first surface 510, and the third connecting part 300 can be fixed on the roof beam 502 and / or the cross beam 503 by the second connecting part 200, so that the external luggage rack and other roof accessories can be stably fixed on the roof by the third connecting part 300.

[0036] It should be noted that in the embodiments of the present application, the fixed connection between the elements can be one or more of riveting, welding, bonding, bolt connection, pin key connection, buckle connection and the like, or can be integrally formed. Those skilled in the art can judge which connection mode to adopt according to the specific situation.

[0037] Further, please refer to Figures 5 to 6 , Figure 5 is Figure 2 the structure diagram of the first connecting part 100 in the embodiment, Figure 6 is Figure 5 the structure diagram of the first connecting part 100 in the embodiment. Alternatively, in the embodiment, the first connecting part 100 is provided with a first fixed part 101 and a first connecting part 102 at two ends respectively.

[0038] Among them, the two ends of the first fixed part 101 are respectively sunken to form a first sub-fixed part 110 and a second sub-fixed part 120, and the first sub-fixed part 110 and the second sub-fixed part 120 are fixed on the first surface 510 respectively, so as to enhance the overall strength of the first connecting part 100 and prevent the first connecting part 100 from being insufficient in strength and causing the vehicle body assembly 10 to be damaged.

[0039] Further, a drainage position 130 is formed between the first sub-fixed part 110 and the second sub-fixed part 120, so that the water flowing to the first fixed part 101 can flow out through the drainage position 130. The drainage position 130 can be a hole position formed between the first sub-fixed part 110 and the second sub-fixed part 120, which is used to prevent the water flowing into the vehicle body groove 501 from being hindered by the first fixed part 101.

[0040] Further, the first surface 510 can be provided with a drainage portion, such as a water guide groove inclined outwardly, for draining water on the first surface 510 to the outside, and the second surface 520 and the third surface 530 can also be provided with drainage portions for draining water to the outside or the vehicle body groove 501. Understandably, the drainage portion 130 can allow water flowing to the first fixed portion 101 to flow out without being blocked at the first fixed portion 101.

[0041] Further, one or more reinforcing portions 160 can be provided between the first fixed portion 101 and the first connecting portion 102, and the reinforcing portions 160 can be reinforcing rib positions protruding from the surface of the first connecting member 100, for increasing the strength of the first clamping portion 140 and the second clamping portion 150. In the embodiment, three protruding reinforcing rib positions are provided between the first fixed portion 101 and the first connecting portion 102, to prevent the first clamping portion 140 and the second clamping portion 150 from being insufficient in strength and causing damage to the vehicle body assembly 10.

[0042] Alternatively, the same side of the two ends of the first connecting portion 102 is respectively formed with the first clamping portion 140 and the second clamping portion 150 protruding away from the first fixed portion 101, for clamping the second connecting member 200 to the two ends of the first connecting portion 102. In addition, the end of the first clamping portion 140 and the second clamping portion 150 away from the first fixed portion 101 is respectively formed with a first limiting portion 1401 and a second limiting portion 1501, which can further stabilize the clamping structure of the first clamping portion 140 and the second clamping portion 150 with the second connecting member 200.

[0043] Please refer to Figure 7 , Figure 7 is Figure 2 the structure schematic diagram of the second connecting member 200 in the embodiment. The two ends of the second connecting member 200 are respectively provided with a second connecting portion 201 and a third connecting portion 202, wherein the second connecting portion 201 is used for clamping the first connecting member 100 in the vehicle body groove 501, and the third connecting portion 202 is used for connecting the third connecting member 300 to the side of the roof beam 502 away from the vehicle body groove 501.

[0044] Wherein, the two ends of the second connecting portion 201 are respectively inwardly recessed to the middle portion to form a third clamping portion 210 and a fourth clamping portion 220, and the end of the third clamping portion 210 away from the fourth clamping portion 220 is sunken to form a fifth clamping portion 230; wherein the fifth clamping portion 230 matches the first clamping portion 140, and the fourth clamping portion 220 matches the second clamping portion 150; the third clamping portion 210 can be extended to the first clamping portion 140, so that the fifth clamping portion 230 can be clamped to the first clamping portion 140, and the fourth clamping portion 220 can be clamped to the second clamping portion 150 at the same time.

[0045] Specifically, the first clamping portion 140 and the second clamping portion 150 are bosses arranged at one end of the first connecting piece 100 for clamping the second connecting piece 200, and the fourth clamping portion 220 and the fifth clamping portion 230 are recesses arranged on the second connecting piece 200 and matched with the second clamping portion 150 and the first clamping portion 140 respectively, for clamping the second clamping portion 150 and the first clamping portion 140 respectively, so as to achieve detachable fixed connection between the first connecting piece 100 and the second connecting piece 200.

[0046] Further, the fifth clamping portion 230 in the embodiment is formed by sinking the end of the third clamping portion 210 away from the fourth clamping portion 220, in other words, the second connecting piece 200 is provided with the third clamping portion 210 formed by further sinking the end of the fifth clamping portion 230 towards the fourth clamping portion 220, and the part of the third clamping portion 210 not forming the fifth clamping portion 230 protrudes from the fifth clamping portion 230. The first clamping portion 140 can be telescoped in the third clamping portion 210, when the first clamping portion 140 abuts against the end of the third clamping portion 210 away from the fifth clamping portion 230, the second connecting piece 200 can adjust the posture so that the fourth clamping portion 220 is clamped to the second clamping portion 150, and at the same time the fifth clamping portion 230 can be clamped to the first clamping portion 140, thereby achieving convenient and stable detachable fixed connection between the first connecting piece 100 and the second connecting piece 200.

[0047] The applicant found that the existing clamping piece has the problems of inconvenient disassembly or unstable connection in structure, and the application of such clamping piece in the connection structure between the external luggage rack and the rain groove of the roof accessory is prone to cause the problems of inconvenient disassembly or unstable installation of the connection structure. The detachable installation is one of the main advantages of the clamping structure, and the application of the detachable installation structure in the connection structure between the rain groove and the roof accessory can facilitate the disassembly of the roof accessory, and can also disassemble the installation structure after disassembly of the roof accessory, without affecting the aesthetics of the vehicle body; and the stable installation is a necessary function to avoid safety hazards in the installation of the roof accessory. Therefore, the vehicle body assembly 10 provided in the embodiments of the present application can be detachably and stably connected to solve the above technical problems. In the embodiments, the first connecting piece 100 and the second connecting piece 200 can be detachably and stably connected by the cooperation of the first clamping portion 140, the second clamping portion 150, the third clamping portion 210, the fourth clamping portion 220 and the fifth clamping portion 230.

[0048] Please refer to Figures 8 to 10 , Figure 8 is Figure 2 the structure diagram when the first connecting piece 100 and the second connecting piece 200 are preliminarily clamped in the embodiments, Figure 9 is Figure 8Structure diagram of the first connecting member 100 and the second connecting member 200 when they are further clamped together, Figure 10 is Figure 9 Structure diagram of the first connecting member 100 and the second connecting member 200 when they are further clamped together.

[0049] During the clamping process of the first connecting member 100 and the second connecting member 200, the third clamping part 210 is first inserted obliquely into the first clamping part 140. Since the fifth clamping part 230 matches the first clamping part 140, when the first clamping part 140 abuts against the end of the third clamping part 210 away from the fifth clamping part 230, the first connecting member 100 has not yet formed a stable connection structure with the second connecting member 200, i.e., at this time, the second connecting member 200 can move relative to the first connecting member 100.

[0050] Further, the first clamping part 140 stays in the third clamping part 210, and the second connecting member 200 is rotated with the end of the fourth clamping part 220 facing the direction of the second clamping part 150, so that the fourth clamping part 220 is in a position corresponding to the second clamping part 150.

[0051] Further, the second connecting member 200 moves in the direction of the second clamping part 150 until the second clamping part 150 and the fourth clamping part 220 complete clamping, at which time the first clamping part 140 also synchronously completes clamping with the fifth clamping part 230. The first clamping part 140, the second clamping part 150, and the third clamping part 210 can cooperate to limit the movement of the fourth clamping part 220 and the fifth clamping part 230, and thus the first connecting member 100 and the second connecting member 200 form a detachable fixed connection structure.

[0052] Further, the first limiting part 1401 and the second limiting part 1501 are protrusions formed at the end of the first clamping part 140 and the second clamping part 150 away from the first fixed part 101. The protruding direction of the protrusions is perpendicular to the second connecting part 201. The first limiting part 1401 and the second limiting part 1501 can cooperate to limit the movement of the fifth clamping part 230 and the fourth clamping part 220 relative to the first clamping part 140 and the second clamping part 150.
