Description

Technical Field

[0001] The present application relates to the automotive field, and in particular to a tailgate limit block assembly and an automobile. Background Art

[0002] With the vigorous development of the national automobile industry, there are more and more brands of automobiles in the Chinese market. The competition between automobile brands is mainly the difference in vehicle quality, so it is particularly important to improve the quality of vehicles. Among them, the quality of opening and closing doors and the difference in the closed state are very important factors in measuring vehicle quality. At present, the common adjustment solution for automobile tailgates is to install tailgate limit blocks for adjustment.

[0003] However, the traditional tailgate limit block cannot be adjusted in height, which may easily lead to problems such as difficulty in closing the tailgate and large surface difference when closing the tailgate, greatly reducing the appearance quality and sealing effect of the car.

[0004] Some existing tailgate limit devices use elastic parts to adjust the height of the tailgate limit block. Although the elasticity of the elastic parts increases the degree of fit, the door needs to be opened and closed continuously, and the stability and accuracy of the elastic connection are lower than those of the rigid connection, which is also prone to malfunction and connection failure. Utility Model Content

[0005] The present application provides a tailgate limit block assembly, which can adjust the height of the limit block and has a stable connection.

[0006] A tailgate limit block assembly includes a door limit assembly and a vehicle frame limit assembly, wherein the door limit assembly includes a fixed bracket, a guide shaft and a limit block, wherein the guide shaft is mounted on the fixed bracket, and the limit block and the limit portion of the vehicle frame limit assembly are abutted against each other, wherein the guide shaft is provided with a plurality of positioning holes along its length direction, and the limit block is fixed on one of the positioning holes to adjust the height of the limit block relative to the limit portion.

[0007] Furthermore, the limiting block has a first limiting surface, the limiting portion has a second limiting surface, the first limiting surface and the second limiting surface are offset against each other, and the first limiting surface is inclined relative to the guide shaft.

[0008] Furthermore, a slideway is formed in the fixed bracket, the slideway and the guide shaft are arranged in the same direction, and the guide shaft is arranged in the slideway.

[0009] Furthermore, the door limit assembly also includes: a base plate, the base plate covers one side of the slide, a plurality of screw holes are formed on the base plate, the screw holes are respectively arranged corresponding to the positioning holes, and a fixing hole is formed on the limit block, and the fixing hole, the positioning hole and the screw hole are used for fixing through a connecting piece.

[0010] Furthermore, the fixing bracket includes a side surrounding portion, the side surrounding portion is frame-shaped, the slideway is formed inside, one end of the side surrounding portion has an opening, and the guide shaft is fixed to both ends of the side surrounding portion.

[0011] Furthermore, the fixing bracket also includes two flange parts, the two flange parts are respectively connected to two sides of the side surrounding part, and the flange parts are fixedly connected to the bottom plate.

[0027] See also Figure 1 to Figure 2 As shown, the tailgate limit block 13 assembly includes a door limit component 1 and a frame limit component 2, the door limit component 1 has a first limit surface A, the frame limit component 2 has a second limit surface B, the first limit surface A and the second limit surface B are in contact with each other, and the door limit component 1 and the frame limit component 2 are limited by the contact between the first limit surface A and the second limit surface B, the first limit surface A and the second limit surface B are both inclined surfaces, and the inclinations of the first limit surface A and the second limit surface B are the same.

[0028] See also Figures 3 to 5 As shown, the door limiting assembly 1 includes a fixed bracket 11, a guide shaft 12 and a limiting block 13. A slideway 111 is formed in the fixed bracket 11. The guide shaft 12 and the slideway 111 are arranged in the same direction. The guide shaft 12 is arranged in the slideway 111. The first limiting surface A is arranged on the limiting block 13. The guide shaft 12 guides the limiting block 13 to slide in the slideway 111. A plurality of gears are formed along the guide shaft 12. The limiting block 13 is fixedly arranged at any gear.

[0029] Specifically, since the first limiting surface A is inclined relative to the slide 111, the distance between the first limiting surface A and the door limiting assembly 1 will change during the sliding process of the limiting block 13 along the slide 111, that is, the height relative to the door limiting assembly 1 will change, and then the first limiting surface A and the second limiting surface B will be fitted at different positions, which is reflected as the multiple gears mentioned above. The effect that can be obtained is: moving the limiting block 13 along the slide 111 to realize the first limiting surface A approaching or moving away from the door limiting assembly 1 to achieve compensation for the door sealing effect.

[0030] Figure 4 In the embodiment, the slide extension direction X, the slide height direction Y and the slide width direction Z are orthogonally arranged, wherein the axial direction of the guide shaft 12 is in the same direction as the slide extension direction X, and the slide 111 limits the freedom of the limit block 13 so that the limit block 13 can only slide in the slide 111 along the slide extension direction X, and the guide shaft 12 plays a guiding role, further guiding the limit block 13 to slide along the slide 111. It is worth noting that the first limit surface A is inclined relative to the slide 111, so that in the process of the limit block 13 sliding along the slide 111, it can be close to or away from the vehicle frame limit assembly 2, so as to adjust the closing quality of the door and the surface difference between the door and the frame.

[0031] The fixed bracket 11 includes a side enclosure portion 112 and a flange portion 113. The side enclosure portion 112 is frame-shaped and has a slideway 111 formed therein.

The two flange portions 113 are respectively connected to both sides of the side enclosure portion 112. Preferably, the fixed bracket 11 is an integrated structure. The side enclosure portion 112 is strip-shaped and is bent to form an unsealed rectangular structure. The unsealed portion is located at one end of the side enclosure portion 112 to form an opening 115. The fixed bracket 11 is integrated to form the slideway 111 only by bending. No welding or other fixing methods are required, so the manufacturing and production are convenient. The flange portion 113 is connected to the two long sides of the rectangular structure. A door mounting hole 114 is provided on the flange portion 113 for fixing to the bottom plate mounting hole 152 and the door.

The fixing holes 132, the positioning holes 121 and the screw holes 151 are provided in the same direction, and each screw hole 151 is directly opposite to a positioning hole 121. Preferably, the fixing holes 132, the positioning holes 121 and the screw holes 151 are all arranged along the height direction Y of the slideway.

[0034] The connecting piece passes through the fixing hole 132, the positioning hole 121 and the screw hole 151 to realize the positioning of the limit block 13, and the limit block 13 can use the connecting piece to fix the fixing hole 132 and any one of the multiple positioning holes 121 / screw holes 151, thereby realizing the position adjustment of the limit block 13, and the position of each positioning hole 121 / screw hole 151 forms a gear position that can be selected for fixing, and the specific connecting piece is the screw 14; at this time, the guide shaft 12 realizes the positioning function of the limit block 13.

[0035] Preferably, the screw 14 passes through the fixing hole 132 , the positioning hole 121 and the screw hole 151 and is fixed on the vehicle body, so as to form a more stable fixation.

[0036] In a preferred embodiment, the fixing hole 132 is formed on the first limiting surface A, so that the screw 14 can be removed and installed when the door limiting assembly 1 is installed, which is convenient and quick.

[0037] A guide hole 131 is provided on the limit block 13 , and the guide hole 131 is provided along the extension direction X of the slideway.
