DETAILED DESCRIPTION

[0047] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0048] Truck front hoods are an integral part of heavy-duty vehicle design, with key functions including protection, aerodynamic optimization, and aesthetics. The front hood is usually located at the front end of the vehicle, covering the engine compartment and protecting the internal mechanical components from the external environment.

[0049] The front cover of the truck is connected to the front of the vehicle by a hinge, and the gap between the two sides of the front cover is adjusted through the mounting holes on the hinge. The existing method of manually adjusting the gap between the two sides of the front cover easily leads to an excessively large gap between the two sides of the front cover, thus affecting product quality.

[0050] Based on the above problems, the present application provides a truck front cover gap adjustment device and method for adjusting the gap between the two sides of the truck front cover and the front of the truck. The embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0051] It should be noted that the truck front hood gap adjustment device and method provided in the present application are not limited to the adjustment of the truck front hood, but are also applicable to the adjustment of products fixed with bolts.

[0052] like Figure 1 As shown, Figure 1 This is a schematic structural diagram of the truck front hood gap adjustment device provided in this application.

[0053] The embodiment of the present application provides a truck front cover gap adjustment device, comprising: a body 100, arranged between the front cover 10 and the front of the vehicle; a driving assembly 200, arranged on the body 100; and an adjustment assembly 300, arranged on the driving assembly 200 and connected to the front cover 10.

[0054] The driving assembly 200 is used to drive the adjusting assembly 300 to move, so that the adjusting assembly 300 drives the front mask 10 to move, so as to adjust the gap between the two opposite sides of the front mask 10 and the front of the vehicle.

[0055] The gap between the two sides of the front cover 10 and the front of the vehicle is adjusted by the cooperation between the driving assembly 200 and the adjusting assembly 300, so as to improve the installation accuracy of the front cover 10.

[0056] The fixing method between the front of the vehicle and the front cover 10 is as follows: a fixed beam 30 is provided on the front of the vehicle, a hinge is provided on the fixed beam 30, the front cover 10 is fixed to the fixed beam 30 through the hinge, the front cover 10 and the hinge are connected by bolts, and the front cover 10 can be flipped open or closed.

[0057] The adjustment assembly 300 can be directly connected to the front mask 10, and after loosening the bolt 22 on the hinge, the adjustment assembly 300 directly adjusts the position of the front mask 10. The adjustment assembly 300 can also be connected to the bolt on the hinge, and the position of the front mask 10 can be adjusted by controlling the bolt 22. Both of these adjustment methods only require loosening the bolt 22 to keep it in a pseudo connection, and the bolt 22 cannot be separated from the front mask 10.

[0058] The pseudo connection of the bolt 22 in this embodiment means that the bolt 22 is loosened to a certain extent, but is not completely separated from the front cover 10, so that the bolt 22 can move in the adjustment hole 21 on the hinge plate 20, and the front cover 10 can also move with the bolt 22.

[0059] During the adjustment process, the bolts on the hinge are first adjusted to a pseudo-link state, and then the position of the front mask 10 is adjusted through the cooperation of the driving assembly 200 and the adjusting assembly 300 to make the gaps on both sides of the front mask 10 equal.

[0060] Combination Figures 1 to 3 As shown, Figure 2 for Figure 1 Exploded diagram of the drive and adjustment components in the Figure 3 for Figure 1 Schematic diagram of the structure of the Chinese body.

[0064] The gaps on both sides of the front mask 10 are relatively small, and the adjustment requires high precision. Therefore, through the cooperation between the first motor 210, the transmission member 220 and the screw rod 230, the position of the adjustment block 310 can be accurately controlled, thereby achieving accurate control of the gap distance of the front mask 10.

[0065] For example Figure 7 As shown, Figure 7 This is a schematic diagram of the structure of the adjustment block in the truck front hood gap adjustment device provided in this application.

A threaded hole is set in the middle of the adjustment block 310, and the screw rod 230 is connected to the threaded hole. The internal thread in the threaded hole cooperates with the external thread on the screw rod 230. When the screw rod 230 rotates under the action of the transmission member 220, it drives the adjustment block 310 to slide horizontally on the slide rail 110 to realize the adjustment of the front mask 10.

[0071] The bolt 22 is connected to the front cover 10 through the adjustment hole 21 to fix the front cover 10 on the hinge plate 20;

[0072] The second motor 320 is disposed on the adjustment block 310 , the connection block 330 is connected to the output end of the second motor 320 , and the connection block 330 is connected with a bolt;

[0073] The second motor 320 controls the connection block 330 to rotate so that the bolt 22 rotates from the fixed connection state to the false connection state;

[0074] The second motor 320 moves along the screw rod 230 under the action of the adjusting block 310 , so that the connecting block 330 moves along the screw rod 230 , and the bolt drives the front mask 10 to move under the action of the connecting block 330 .

[0075] Among them, the hinge plate 20 is arranged on the fixed beam 30 of the front of the vehicle, the upper end is connected to the fixed beam 30, and the lower end is bolted to the front cover 10. The front cover gap adjustment device of the truck in the embodiment of the present application is connected to the lower end of the hinge plate 20.

[0076] The bolt 22 is divided into a screw rod and a head, and the diameter of the adjustment hole 21 is larger than the diameter of the bolt 22 and smaller than the diameter of the head, so that the screw rod has a certain movement space in the adjustment hole 21.

[0077] Exemplarily, the adjustment hole 21 may be a circular hole or a horizontal strip hole.

[0078] The second motor 320 controls the connection block 330 to loosen the bolt 22, which does not require manual operation, saving time and effort.

[0079] In the embodiment of the present application, the main body 100 includes a base 120 , and the base 120 is connected to the front of the vehicle.

[0080] The four corners of the base 120 are provided with threaded holes, and the bolts 22 pass through the threaded holes to fix the base 120 on the front of the vehicle.

[0081] In the embodiment of the present application, the body 100 further includes a protective cover 130 and a fixing plate 140 disposed on the base 120 , and a bearing seat 150 is disposed on the fixing plate 140 ;

[0082] The slide rail 110 is located between the protective cover 130 and the fixed plate 140, the transmission member 220 is located in the first protective cover 130, the output shaft of the first motor 210 extends into the protective cover 130 and is connected to the transmission member 220, one end of the screw rod 230 extends into the protective cover 130 and is connected to the transmission member 220, and the other end of the screw rod 230 is connected to the bearing seat 150.

[0083] The protective cover 130 is used to protect the motor and the transmission member 220 , and the bearing seat 150 is used to fix the screw rod 230 .

[0084] like Figure 5 As shown, Figure 5 for Figure 1 sectional view of .

[0085] In the embodiment of the present application, the transmission member 220 includes a first bevel gear 221 and a second bevel gear 222 . The first bevel gear 221 is disposed on the first motor 210 , and the second bevel gear 222 is disposed on the screw rod 230 . The first bevel gear 221 meshes with the second bevel gear 222 .

[0086] A bearing seat 150 is also provided on the protective cover 130 , and two ends of the screw rod 230 are respectively connected to the two bearing seats 150 to better fix the screw rod 230 .

[0087] At least the upper end of the first motor 210 is located outside the protective cover 130 , and the output end is located inside the protective cover 130 , and is fixed through the mounting holes on the protective cover 130 .

[0088] The cooperation between the first bevel gear 221 and the second bevel gear 222 can realize vertical transmission between the first motor 210 and the lead screw 230 .

[0089] Exemplarily, the first motor 210 is disposed in the protective cover 130 , the transmission member 220 is a coupling, and the output shaft of the first motor 210 is directly connected to the screw rod 230 through the coupling to directly connect the first motor 210 to the screw rod 230 .

[0090] In the embodiment of the present application, a limiting groove 331 is provided at one end of the connection block 330 facing the front cover 10 , and at least part of the bolts 22 can be inserted into the limiting groove 331 to fix the bolts on the connection block 330 .

[0091] The shape of the limiting groove 331 is the same as the shape of the head of the bolt 22 , and the shape of the limiting groove 331 is hexagonal, so that the connection between the limiting groove 331 and the bolt 22 is tighter.

[0092] In the embodiment of the present application, the connection block 330 is a magnet block, and magnetic attraction is generated between the magnet block and the bolt 22 to strengthen the connection between the bolt 22 and the connection block 330 .

[0093] Exemplarily, the connection block 330 is made of alloy, and a magnet is disposed inside the connection block 330. The connection between the bolt 22 and the connection block 330 is strengthened by generating magnetic attraction between the magnet and the bolt 22.

[0094] like Figure 6 As shown, Figure 6 This is a schematic diagram of the installation of the distance sensor 400 in the truck front hood gap adjustment device provided in the present application.

[0095] In the embodiment of the present application, a control component and two distance sensors 400 connected to the control component are also included.

[0096] Two distance sensors 400 are disposed at two ends of the front mask 10 to detect the gap lengths at the two ends and transmit the lengths to the control component.

[0097] The control component is connected to the first motor 210 and the second motor 320 respectively, and is used to control the start and stop of the first motor 210 and the second motor 320.

[0098] Among them, the first motor 210 and the second motor 320 are both remote-controlled motors, which can be connected to the control component by wire or wirelessly. Since the remote-controlled motor is a prior art, it will not be described in detail in this application.

[0099] The control assembly can be a handheld controller or an automatic controller.

[0100] The handheld controller can receive and display the values ​​of the two distance sensors 400, and control the first motor 210 or the second motor 320 to start or stop, thereby adjusting the gap length of the front mask 10. For ease of understanding, the handheld controller can be a remote controller with a shape and function similar to an air conditioner remote controller.

[0101] The automatic controller is disposed in the front of the vehicle, and adjusts the front mask 10 through the first motor 210 and the second motor 320 according to the gap length input in advance, so that the gap lengths on both sides of the front mask 10 meet the preset value.

[0102] During the process of the second motor 320 controlling the rotation of the bolt 22, it is impossible to determine whether the bolt 22 is in a pseudo-connection state or a fixed connection state only by the second motor 320. The solution of this embodiment is to input the number of rotations of the output shaft of the second motor 320 into the control component in advance to control the state of the bolt 22.

[0103] For example, in order for the bolt 22 to enter the pseudo-connected state from the fixed connection state, the output shaft of the second motor 320 needs to rotate 10 times (the number of rotations can be determined based on the number of times the bolt 22 is manually rotated). The control component inputs a command of 10 turns in advance. When it is necessary to control the second motor 320 to work, the control component outputs the command of the second motor 320 to rotate 10 times, thereby causing the bolt 22 to enter the pseudo-connected state from the fixed connection state. Otherwise, the bolt 22 enters the fixed connection state from the pseudo-connected state.

[0104] The truck front cover gap adjustment device of the embodiment of the present application enables production personnel to avoid manually loosening and tightening the bolts 22 when assembling a vehicle equipped with the electric adjustment device. The front cover 10 can adapt to the gaps on the left and right sides and automatically adjust the gaps on the left and right sides to be consistent, which is accurate and efficient.

[0105] The distance sensor 400 in the truck front cover gap adjustment device of this embodiment monitors the difference gap between the left and right sides of the front cover 10. Through the cooperation of the driving component 200 and the adjusting component 300, the adjusting component 300 controls the hinge bolt 22 of the front cover 10 to perform horizontal reciprocating motion, thereby realizing the control of the gap length of the front cover 10, making the vehicle appearance control more precise and the assembly more convenient and intelligent.

[0106] The present application also provides a method for adjusting the gap of a truck front cover 10, the method is as follows:

[0107] Obtain the gap distance value between the two ends of the front mask 10 and the front of the vehicle;

[0108] According to the gap distance value, the driving assembly 200 is controlled to start, so as to drive the adjusting assembly 300 on the driving assembly 200 to move, so as to adjust the gaps on both sides of the front mask 10, until the gap distance value reaches a preset value.

[0109] The preset value includes but is not limited to the value when the gap distance between the two ends of the front cover 10 and the front of the vehicle is equal.

[0110] Combination Figure 8 and Fig. 9 As shown, Figure 8 A working principle diagram of the gap adjustment method for the truck front cover 10 provided in the present application for automatically adjusting the gap during assembly. Fig. 9 The working principle diagram of the gap adjustment method for the truck front cover 10 provided in the present application for automatically adjusting the gap after assembly. The working principle of the automatic gap adjustment will be described below in combination with the states of the truck during and after assembly.

[0111] like Figure 8As shown, when the vehicle is assembled, the front mask 10 is pre-installed on the hinge plate 20, and the bolts 22 on the hinge plate 20 are in a pseudo-connected state. The connecting block 330 is connected with the bolts, and the distance sensors 400 arranged on the end faces of both sides of the front mask 10 monitor that the difference in the gap between the two sides of the front mask 10 is greater than the system preset value. The control component controls the first motor 210 to start working, and through the transmission cooperation between the transmission shaft, the screw rod 230, the adjustment block 310 and the second motor 320, the connecting block 330 drives the front mask 10 to move horizontally until the difference in the gap between the two sides of the front mask 10 is less than the system preset value. The control component controls the first motor 210 to stop working, and the control component controls the second motor 320 to start, tighten the bolts 22 of the front mask 10, and then end the work.

[0112] See Fig. 9 As shown, when the vehicle is assembled and stationary, the front cover 10 is fixed on the hinge plate 20, and the bolts 22 on the hinge plate 20 are in a fixed connection state. The connecting block 330 is connected with the bolts, and the distance sensors 400 arranged on the end surfaces of both sides of the front cover 10 monitor that the difference in the gap between the two sides of the front cover 10 is greater than the system preset value. The second motor 320 is controlled by the control component to loosen the bolts 22 on the hinge plate 20 to put it in a pseudo connection state. When the second motor 320 rotates a preset number of circles, the second motor 320 stops working, and the control component controls the first motor 210 to start working. Through the transmission cooperation between the transmission shaft, the screw rod 230, the adjustment block 310 and the second motor 320, the connecting block 330 drives the front cover 10 to move horizontally until the difference in the gap between the two sides of the front cover 10 is less than the system preset value, the first motor 210 stops working, the second motor 320 starts, tightens the bolts 22 on the hinge plate 20, and then ends the work.

[0113] The method for adjusting the gap of a truck front mask 10 provided in the embodiment of the present application adjusts the gap between the two sides of the front mask 10 and the front of the vehicle through the cooperation between the driving component 200 and the adjusting component 300 in the truck front mask gap adjusting device, thereby improving the installation accuracy of the front mask 10.
