Description

Technical Field

[0001] The utility model relates to the technical field of automobile doors, in particular to a door stopper structure and a vehicle. Background Art

[0002] The door structure of a car generally includes a door limiter, which is a key component that connects the door to the side of the car body and limits the door opening. The door limiter mainly includes a limiter box, a limiter main arm, and a limiter bracket. The limiter bracket is installed on the outer panel of the side of the car body. The limiter box of the door limiter is fastened to the door with two screws / nuts. When the door is opened, the limiter box will move along the limiter main arm. Due to the different height structures on the limiter main arm, the elastic element will have different elastic deformations, and at each limit position point, it can play a role in limiting the door.

[0003] The door limiter is generally installed in the gap between the door and the body. The installation space is extremely narrow. The limiter bracket is installed on the side wall of the side panel corresponding to the gap and extends along the Y-axis direction of the body (body width direction). The extended end is rotatably connected to one end of the limiter main arm, so that the angle between the limiter bracket and the limiter main arm is arranged at a small angle (acute angle). The following problems exist: First, since the limiter bracket itself is installed on the side wall of the side outer panel, in order to accommodate the part of the limiter bracket along the Y-axis direction of the vehicle body, the side wall of the side outer panel needs to be set to a larger size along the Y-axis direction, that is, the H value is larger, generally 75-90mm, but the side outer panel is a stamped part, and when the H value is larger, it will cause cracking problems in the stamping; second, when arranging the door wiring harness, it is necessary to pass through the limiter bracket and the limiter main arm for routing, but because the angle α between the limiter bracket and the limiter main arm is an acute angle, the layout space of the door wiring harness is limited, and the optimal layout of the door wiring harness is limited.

[0036] It should be noted that the length direction of the vehicle body described below is the X-axis direction of the vehicle body coordinate system, and the width direction of the vehicle body is the Y-axis direction of the vehicle body coordinate system.

[0037] See also Figure 4 , 5As shown in 6, the common drawstring door limiter has the function of limiting when the door is fully opened or half opened. For the convenience of distinction, the limiter bracket in the prior art is set as the original limiter bracket 1', and its working principle is as follows: the original limiter bracket 1' is fastened to the car body by mounting bolts, and the limiter box 3 is fastened to the car door by two mounting screws. When the door is opened, the limiter box 3 will move along the limiter main arm 2. Since the limiter main arm 2 has different height structures, the elastic rubber block will have different elastic deformations, so people need to use different forces to close the door when opening the door. At each limiting position point, it can play a limiting role on the car door. This structure is the most widely used, and its specific forms are also varied: some limiter main arms 2 are stamped structures. The maximum torque of the door limiter of this structure is about 35N.m, the length is generally about 60mm, and the angle α between the original limiter bracket 1' and the limiter main arm 2 is an acute angle. Generally, it is installed between the gap between the door and the body, and the original limiter bracket 1' is fixedly installed on the side wall 42 of the side outer panel 4 corresponding to the gap. In order to accommodate the length of the original limiter bracket 1' along the Y-axis direction of the body, the depth value of the side wall 42 of the side outer panel 4 along the width direction of the body is H value, and H value is generally 75-90mm.

[0038] The side panel 4 of the vehicle body is one of the outer covering parts with the largest size and the most complex shape among the sheet metal parts of the automobile. Its surface quality requirements are high, and no defects such as wrinkles, scratches, burrs, depressions, slip lines, distortions, and indentations are allowed. The side panel 4 is formed by stamping galvanized steel sheets. There are three steps and four corners at the door frame of the side panel 4. The shape is quite complex. The drawing coefficient at this position is also the largest. It is formed by one-time drawing. The corner is drawn and bent at the same time, and the outer side of the corner is subjected to multiple tensile stresses. The yield strength of the plate is relatively high, so the multiple tensile stresses make the steel plate thinner rapidly to meet the needs of continuous forming. If the metal plastic flow of other parts cannot be supplemented in time, the steel plate becomes thinner and thinner. When the tensile stress exceeds the allowable tensile strength of the plate, the plate quickly loses stability and eventually cracks, which not only affects production but also causes economic losses. With the help of CAE (computer aided engineering) analysis technology, it is found that the large H value is one of the main reasons for the cracking of the side panel 4.

[0039] The door harness is the guarantee for the normal operation of the electrical components on the door. It connects the power supply with switches, buttons, window lifters, speakers, door locks and other important components. The layout of the door harness is directly related to the realization of the harness function and the safety of the electrical components. Therefore, when arranging the harness, it is necessary to consider the fixing method, harness direction, waterproof measures, anti-magnetic measures, anti-damage measures, connector selection and matching, etc., to achieve the optimization of harness design and layout. However, the angle α between the original limiter bracket 1' and the limiter main arm 2 is an acute angle, which is not conducive to optimizing the layout of the door harness.

[0040] The above series of rigid requirements for the door limiter limit the structural design and installation of the door limiter, which cannot meet the needs of users. Therefore, the utility model changes the structure of the door limiter so that the design of the door limiter structure matches the design requirements of the side outer panel 4 and the requirements for the optimized layout of the door wiring harness.

[0041] See also Figure 1 and Figure 2 As shown, the technical solution of the utility model is described in detail below in conjunction with specific embodiments:

[0042] The embodiment of the present utility model provides a door stopper structure, comprising a stopper bracket 1, a stopper main arm 2 and a stopper box 3. The stopper bracket 1 comprises a fixed end 11 and a connecting end 12 arranged opposite to each other, and a stopper bracket arm 112 connected between the fixed end 11 and the connecting end 12. Figure 2 , the length L of the limiter bracket arm 112 is the length of the straight section between the fixed end 11 and the connecting end 12, and the length L is 50-60mm. One end of the limiter main arm 2 is rotatably connected to the connecting end 12 of the limiter bracket 1, and the limiter box 3 is slidably arranged on the limiter main arm 2; wherein, the fixed end 11 of the limiter bracket 1 is connected to the outer facade 41 of the side outer panel 4 of the vehicle body along the width direction of the vehicle body, so that when the door is in a closed state, the angle α between the limiter bracket arm 112 and the limiter main arm 2 is greater than 90°. The installation position of the limiter bracket 1 on the side outer panel 4 is changed from the original side wall 42 of the side outer panel 4 to the outer facade 41. At this time, the setting of the H value of the side wall 42 of the side outer panel 4 can be unaffected by the original limiter bracket 1'. The problem of cracking of the side outer panel 4 caused by a large H value is solved.

[0043] In one embodiment of the present invention, the stopper bracket 1 is formed by bending a single layer of steel plate, and the fixed end 11 of the stopper bracket 1 is fixedly connected to the outer facade 41 of the side outer panel 4 through the fixing plate 13. At this time, the stopper bracket 1 and the outer facade 41 of the side outer panel 4 are fixed at a single point.

[0044] In one embodiment of the utility model, the limiter bracket 1 is a U-shaped double-layer steel plate integrally bent or die-cast aluminum structure, so that the cross section of the limiter bracket 1 is an inverted U-shape, and the two sides of the U-shape of the fixed end 11 of the limiter bracket 1 are respectively fixedly connected to the outer facade 41 of the side outer panel 4 through a corresponding pair of fixing plates 13. At this time, the limiter bracket 1 and the outer facade 41 of the side outer panel 4 are fixed at two points. The limiter main arm 2 includes a supporting end 21 and a mounting end 22 arranged oppositely, and the mounting end 22 is rotatably connected to the connecting end 12 of the limiter bracket 1. The limiter main arm 2 is rod-shaped, and the supporting end 21 of the limiter main arm 2 is T-shaped. The limiter main arm 2 passes through the limiter box 3, so that the limiter box 3 is slidably arranged between the supporting end 21 and the mounting end 22 of the limiter main arm 2. Some limiter boxes 3 use needle rollers, some limiter boxes 3 use balls, and some limiter boxes 3 use sliders, etc., but the principle of limiting is the same. The mounting end 22 of the limiter main arm 2 is arranged between the U-shaped openings of the connection end 12 of the limiter bracket 1, and the pin shaft 14 passes through the connection end 12, so that the mounting end 22 of the limiter main arm 2 is rotatably connected with the connection end 12 of the limiter bracket 1. The angle between the limiter bracket arm 112 of the limiter bracket 1 and the limiter main arm 2 is α, and α>90°, so that the door harness is not affected and constrained, and the door harness layout is optimized.

[0045] In order to achieve the above-mentioned purpose and other purposes of the utility model, the utility model also provides a vehicle door limiter structure, including: a limiter bracket 1, a limiter main arm 2, a limiter box 3, a vehicle door and a side outer panel 4 of a vehicle body. The limiter bracket 1 includes a fixed end 11 and a connecting end 12 arranged opposite to each other, and a limiter bracket arm 112 connecting the fixed end 11 and the connecting end 12. One end of the limiter main arm 2 is rotatably connected to the connecting end 12 of the limiter bracket 1. The limiter box 3 is slidably arranged on the limiter main arm 2. The vehicle door and the limiter box 3 are fixedly connected. The fixed end 11 of the limiter bracket 1 is connected to the outer facade 41 of the side outer panel 4 along the width direction of the vehicle body, so that when the vehicle door is in a closed state, the angle α between the limiter bracket arm 112 and the limiter main arm 2 is greater than 90°.

[0046] To achieve the above and other purposes of the utility model, the utility model also provides a vehicle, including the above-mentioned door stopper structure. The side outer panel 4 of the vehicle body includes an outer facade 41 and a side wall 42 that bends and extends from the outer facade 41 to a direction away from the outer facade 41. The depth value of the side wall 42 along the width direction of the vehicle body is H value, and the H value satisfies 35-40mm. The H value is reduced by more than half compared with the original value, which greatly reduces the risk of cracking of the side outer panel 4 during molding.

[0047] In summary, (1) the door limiter structure of the utility model matches the side outer panel 4 with an H value of 35-40mm, which solves the problem of cracking caused by stamping when the H value is large. (2) The door limiter structure of the utility model matches the side outer panel 4 with an obtuse angle α, which solves the problem of limiting the layout space of the door wiring harness, so that the door wiring harness can be optimally arranged. (3) The limiter bracket 1 of the door limiter structure of the utility model is a single-layer steel plate integrally bent and formed, or a U-shaped double-layer steel plate integrally bent and formed, or a die-cast aluminum structure. According to different selections and the fixed installation of the facade 41 of the side outer panel 4, it can be selected as a single-point fixation or a double-point fixation, which solves the problem of the original narrow installation space and makes the installation more convenient and reliable.

[0048] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
