Description

Technical Field

[0001] The utility model relates to a connecting device, in particular to a connecting device for fixing an exterior trim panel at an A-pillar position. Background Art

[0002] The body of a car provides a relatively closed space for the car. The structure of the car body includes the A-pillar beam, the side beam and the C-pillar beam connected together. These three structures constitute the side structure of the car body. A top beam is connected between the two separated side structures. These structures play a decisive role in the strength of the car body. There are three pillars on the car body, from the front to the rear of the vehicle, they are the front pillar (A-pillar), the middle pillar (B-pillar) and the rear pillar (C-pillar). The pillar between the windshield and the left front door is called the A-pillar. The structure of the A-pillar includes an iron A-pillar beam, which plays a supporting role. A decorative panel for decorative purposes needs to be set on the outside of the A-pillar beam. For some lightweight vehicles, such as small electric tricycles or electric four-wheelers, to achieve the fixing of the decorative panel, the existing ones are generally fastened with screws. If the screws are set inside the exterior panel, it is troublesome to screw the screws. If the screws are screwed from the outside, the existence of the screws will cause the sealing of the exterior panel to be poor.

[0003] A Chinese patent document (publication number: CN 202935286U) discloses an A-pillar upper trim and a car having the A-pillar upper trim, which relates to the field of automobile technology and is invented to solve the problem of having a good effect on the surround sound in the car. The A-pillar upper trim includes a plate body, a speaker assembly hole is opened on the plate body, and a speaker is installed in the speaker assembly hole. The A-pillar upper trim is used in the car. The utility model is suitable for the assembly of speakers in the car.

[0004] The decorative panel is fixed on the A-pillar beam by means of the elastic member and the plug-in interface. This connection method is prone to aging and deformation of the elastic member and the plug-in interface, which may affect the stability of the decorative panel on the vehicle body, and a large gap may be formed between the decorative panel and the A-pillar beam. Rainwater may easily enter the A-pillar beam through the gap, causing corrosion to the A-pillar beam, which will affect the overall structural strength of the vehicle body. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a vehicle A-pillar exterior panel connection device, which can ensure that the exterior panel is firmly connected to the A-pillar beam.

[0006] To solve the above technical problems, the technical solution of the present utility model is as follows: a connecting device for the outer trim panel of a vehicle A-pillar, including a vehicle body, on which there is an A-pillar beam, and the outer trim panel is used to cover the outer side surface of the A-pillar beam. It is characterized in that mounting ribs are formed on the A-pillar beam, the mounting ribs are strip-shaped and extend in the length direction of the A-pillar beam. A number of connection ports are provided on the A-pillar beam, and these connection ports are spaced apart on the A-pillar beam. Among them, two adjacent connection ports form a pair, and the two connection ports in a pair of connection ports are staggered with each other in the circumferential direction of the mounting rib; a number of plugs are provided on the back surface of the outer trim panel, and the positions of the plugs correspond to those of the connection ports one by one, and one plug is inserted into one connection port; the connection ports correspond to the sizes of the inserted plugs.

[0007] When the outer trim panel is installed on the A-pillar beam, the two connection ports in a pair of connection ports can be inserted and matched with the corresponding plugs from two different directions and positions, so as to realize the connection and fixation between the outer trim panel and the A-pillar beam. Usually, between multiple pairs of connection ports, the positions of the corresponding connection ports are the same.

[0008] Further, the cross-section of the mounting rib is "冂", and the two connection ports in a pair of connection ports are respectively located on two adjacent surfaces of the mounting rib. This kind of mounting rib is convenient for processing and forming, and is convenient for installing the outer trim panel on the A-pillar beam. The two plugs in a pair of plugs can firmly fix the outer trim panel to the A-pillar beam.

[0009] Further, the mounting rib is hollow. The hollow mounting rib is convenient for adjusting the position of the plug in the mounting rib, so as to be able to well adapt to the plug being inserted and matched with the mounting rib from different positions.

[0010] Further, corresponding to the pair of connection ports arranged in pairs, the plugs are also arranged in pairs. Among a pair of plugs, one plug is a flat plug and the other plug is a bent plug. The flat plug is in a straight plate shape and the bent plug is in an L shape. The plugs with two structural forms can well adapt to the insertion and matching of the connection ports on the mounting rib from different directions, making the operation of assembling the outer trim panel to the A-pillar beam convenient and fast.

[0011] Further, a number of sheet-shaped reinforcing pieces are integrally formed between the flat plug and the bent plug and the inner surface of the outer trim panel respectively. The arrangement of the reinforcing pieces makes the plugs have good firmness on the outer trim panel, and is convenient for helping the outer trim panel to be firmly connected to the A-pillar beam.

[0012] Further, the plugs are offset on the outer trim panel, and these plugs are arranged to be biased towards one side in the width direction of the outer trim panel. The plugs being offset on the outer trim panel can well adapt to the setting method in which the two plugs are staggered in the circumferential direction of the mounting rib.

[0013] Compared with the prior art, the utility model has the beneficial effect that by forming a mounting rib on the A-pillar beam, and the mounting rib extends along the length direction of the A-pillar beam, the strength of the A-pillar beam can be effectively improved on the basis of forming a mounting structure on the A-pillar beam. The mounting rib is formed, and the coupling interface is set on the mounting rib, so that a connection structure for connecting with the exterior panel is formed on the A-pillar beam, and the connection and fixation between the exterior panel and the A-pillar beam can be manually realized without the aid of screws. By setting the position between the two coupling interfaces in a pair of coupling interfaces, and the corresponding setting position of the plug and the coupling interface, the connection firmness of the exterior panel on the A-pillar beam is good.

[0021] In conjunction with the drawings of the specification, the vehicle A-pillar exterior panel connection device is used to achieve the connection and fixation of the exterior panel 5 on the A-pillar beam 3. Figure 1 As shown in the figure, the A-pillar beam 3 is located outside the front windshield 1 of the vehicle body. The structure of the connection device includes a vehicle body, and side structures are formed on both sides of the vehicle body. The A-pillar beam 3 in the side structure is located at the front side, and the side beam 2 is located at the top edge position. The side structures on both sides are connected into a whole through several top beams 4. The side structures and the top beam 4 determine the strength of the vehicle body.

[0022] The outer contour shapes of both the exterior trim panel 5 and the A-pillar beam 3 are similar. The exterior trim panel 5 covers the outer side surface of the A-pillar beam 3 to cover the A-pillar beam 3. The A-pillar beam 3 is generally made of iron material and can be integrally formed by stamping. Mounting ribs 31 are formed on the A-pillar beam 3. The mounting ribs 31 are strip-shaped and extend in the length direction of the A-pillar beam 3. The mounting ribs 31 can be formed protruding on the outer side surface of the A-pillar beam 3, or two grooves 33 can be formed on the outer side surface of the A-pillar beam 3, and the mounting ribs 31 are formed between the two grooves 33. Figure 4 As shown in Figure 4 , the mounting ribs 31 are formed between the two grooves 33. The cross-section of the mounting ribs 31 is "冂". Two of the pair of connection ports 32 are respectively located on two adjacent surfaces of the mounting ribs 31. Moreover, the mounting ribs 31 are of a hollow structure.

[0023] There are multiple connection ports 32, and these connection ports 32 are arranged at intervals along the length direction of the A-pillar beam 3. Among them, two adjacent connection ports 32 form a pair. The interval distance between different pairs of connection ports 32 in the length direction of the mounting ribs 31 is relatively large, and several pairs of connection ports 32 are provided on the mounting ribs 31. For the two connection ports 32 in a pair of connection ports 32, their positions are required to be staggered in the circumferential direction of the mounting ribs 31. Corresponding to the connection ports 32, a number of plugs are provided on the back surface of the exterior trim panel 5, and the positions of the plugs correspond to those of the connection ports 32 one by one. One plug is inserted into one connection port 32. The connection ports 32 correspond to the sizes of the inserted plugs. This size refers to the size in the length direction of the mounting ribs 31, and the size of the connection ports 32 should be slightly larger than or equal to the size of the plugs. In the width direction of the mounting ribs 31, the size of the connection ports 32 should be slightly larger than the size of the plugs. Corresponding to the connection ports 32 arranged in pairs, the plugs are also arranged in pairs. Among a pair of plugs, one plug is a flat plug 52, and the other plug is a folded plug 51. The flat plug 52 is in a straight plate shape, and the folded plug 51 is in an L shape. A number of sheet-like reinforcing pieces 53 are integrally formed between the flat plug 52 and the folded plug 51 and the inner surface of the exterior trim panel 5 respectively. The reinforcing pieces 53 on the same plug are arranged side by side at intervals.

[0024] The plugs are offset on the exterior trim panel 5, and these plugs are arranged towards one side in the width direction of the exterior trim panel 5. More specifically, when the exterior trim panel 5 is installed on the A-pillar beam 3, the plugs on the exterior trim panel 5 are biased towards the front side of the vehicle.

[0025] When installing the exterior trim panel 5 on the A-pillar beam 3, first insert the folding plug 51 into the connecting port 32 on the side of the mounting rib 31 accordingly. After being inserted into place, press the exterior trim panel 5 toward the A-pillar beam 3 on the side facing the front end of the vehicle, so that the flat plug 52 is inserted into the corresponding connecting port 32 on the upper surface of the mounting rib 31, and the folding plug 51 continues to penetrate into the inner side of the mounting rib 31, thereby ensuring that the exterior trim panel 5 is firmly installed on the outer surface of the A-pillar beam 3.
