Description

An instrument panel assembly adjustment structure, an instrument panel assembly, and a vehicle Technical Field

[0001] This application relates to an instrument panel assembly adjustment structure, an instrument panel assembly, and a vehicle, belonging to the field of vehicle technology. Background Technology

[0002] The comfort of the driver's area is related to the driver's occupational health and is very important for buses. Currently, most mainstream buses in China are equipped with an adjustable dashboard assembly. By adjusting the height and angle of the dashboard assembly, drivers of different heights and builds can drive in a healthy and comfortable posture.

[0003] For example, Chinese utility model patent CN221562807U discloses an instrument panel assembly adjustment structure and a vehicle. The instrument panel assembly adjustment structure includes a base for fixed connection to the vehicle body, a connecting bracket for connecting the instrument panel and steering column, and a linkage bracket connected to the connecting bracket and moving up and down with it. A height adjustment drive mechanism for driving the connecting bracket to move up and down is installed between the base and the connecting bracket. An angle adjustment drive mechanism for driving the connecting bracket to swing back and forth around its connection position with the height adjustment drive mechanism is connected between the connecting bracket and the linkage bracket. In use, under the control of the height adjustment drive mechanism, the connecting bracket and the linkage bracket move up and down to adjust the height of the instrument panel and steering wheel, and the angle adjustment drive mechanism moves up and down with the connecting bracket and the linkage bracket. When the connecting bracket moves to the target height position, activating the angle adjustment drive mechanism causes the connecting bracket to swing back and forth around its connection position with the height adjustment drive mechanism, thereby adjusting the front and rear angles of the instrument panel and steering wheel.

[0004] The aforementioned linkage brackets are two in number, located on the left and right sides of the base respectively. They consist of numerous components, and both ends of the angle adjustment drive mechanism need to be hinged to their corresponding linkage brackets, resulting in a complex connection structure. Furthermore, the two linkage brackets are bolted to the two guide plates of the base and the two connecting arms of the connecting bracket. The output end of the height adjustment drive mechanism is only hinged to one bolt on one side, causing the applied force at the output end to be offset in the left-right direction. During height adjustment, the force on the connecting bracket is not centered in the left-right direction, easily leading to jamming. Additionally, the angle adjustment drive mechanism includes two output ends. Although these two output ends are hinged to the connecting arms on both sides of the connecting bracket, making the force on the connecting bracket more centered during angle adjustment, the structure of the angle adjustment drive mechanism is complex, resulting in high configuration costs and complicated assembly operations. Summary of the Invention

[0005] The purpose of this application is to provide an adjustment structure for an instrument panel assembly to solve the problems in the prior art, such as the large number of parts caused by setting two linkage brackets, the complex connection structure caused by both ends of the angle adjustment drive mechanism needing to be hinged to the corresponding linkage brackets, and the connection bracket being misaligned in the left and right directions and prone to jamming due to the output end of the height adjustment drive mechanism only being hinged to the bolt on one side. The purpose of this application is also to provide an instrument panel assembly and a vehicle to solve the above problems.

[0006] To achieve the above objectives, the instrument panel assembly adjustment structure in this application adopts the following technical solution: An instrument panel assembly adjustment structure includes a base for fixed connection with the vehicle body and a connecting bracket for connecting the instrument panel and the steering column. The base includes two guide plates, left and right. A linkage seat is installed between the two guide plates along the vertical direction. The linkage seat is hinged to the left and right sides of the connecting bracket through hinge components. A height adjustment drive mechanism for driving the linkage seat and the connecting bracket to move up and down is connected between the linkage seat and the base. An angle adjustment drive mechanism for driving the connecting bracket to swing back and forth around the hinge components is connected between the linkage seat and the connecting bracket.

[0007] The beneficial effects of the above technical solution are as follows: This application is an invention that changes the element relationship, altering the number and placement of the linkage brackets in the prior art, replacing them with only one linkage seat, thus reducing the number of parts. Specifically, the linkage seat is guided and installed between two guide plates in the vertical direction. The linkage seat is hinged to the left and right sides of the connecting bracket via hinge components. A height adjustment drive mechanism is connected between the linkage seat and the base. The height adjustment drive mechanism first applies force to the linkage seat, which then transmits it to the connecting bracket. Because the linkage seat is located between the two guide plates, compared to the prior art, the force on the connecting bracket is more centrally distributed in the left and right directions, reducing the risk of jamming. Simultaneously, an angle adjustment drive mechanism is connected between the linkage seat and the connecting bracket to drive the connecting bracket to swing back and forth around the hinge component. The angle adjustment drive mechanism is connected to one linkage seat, simplifying the connection structure compared to the prior art which requires connecting two linkage brackets.

[0041] To address the technical problems existing in the prior art, the basic concept of this application is to set only one linkage seat, reduce the number of parts, and the linkage seat is located between two guide plates. The height adjustment drive mechanism is connected to the linkage seat, so that the force on the connecting bracket is more centered. At the same time, the angle adjustment drive mechanism is connected to one linkage seat, simplifying the connection structure.

[0042] The features and performance of this application will be further described in detail below with reference to the embodiments.

[0043] Embodiment 1 of the dashboard assembly adjustment structure in this application: As shown in Figures 1, 2, 3, 4, and 5, the dashboard assembly adjustment structure includes a base for fixed connection with the vehicle body and a connecting bracket for connecting the dashboard and the steering column 14. The base includes a base plate 1 and two left and right fixing seats 2 fixed on the base plate 1. Each fixing seat 2 includes a guide plate 2-1, and the two guide plates 2-1 are arranged parallel to each other. The base plate 1 is provided with a connecting structure for fixed connection with the vehicle body. This connecting structure is specifically a second bent edge 1-2. The base plate 1 is fixedly connected to the crossbeam 23 (shown in Figure 3) in front of the vehicle cab through the second bent edge 1-2.

[0044] The connecting bracket includes a connecting seat 3 for connecting the directional column 14 and a mounting bracket 4 fixed to the connecting seat 3 for mounting the instrument panel. Referring to Figures 1-5 and Figure 7, the connecting seat 3 includes two connecting arms 3-1 (left and right), a connecting cylinder 3-2 for connecting the directional column 14, and a connecting plate 3-3 for connecting the mounting bracket 4. The two connecting arms 3-1 are located between two guide plates 2-1, and a linkage seat 5 is mounted between the two guide plates 2-1 in a vertical direction. Referring to Figures 8 and 9, the linkage seat 5 includes a linkage plate 5-1 and linkage sidewalls 5-2 connected to the left and right sides of the linkage plate 5-1. Hinged arms 5-3 are respectively provided on the two linkage sidewalls 5-2. The two hinged arms 5-3 are hinged to the two connecting arms 3-1 through hinge components, and the hinge components are vertically guided by the guide plates 2-1, thus achieving hinged connection between the linkage seat 5 and the left and right sides of the connecting bracket through the hinge components.

[0045] A height adjustment drive mechanism is connected between the linkage seat 5 and the base to drive the linkage seat 5, the connecting seat 3, and the mounting bracket 4 to move up and down. During adjustment, the height adjustment drive mechanism first applies force to the linkage seat 5, and then the linkage seat 5 transmits the force to the connecting bracket. Since the linkage seat 5 is located between the two guide plates 2-1, compared with the prior art, the force on the connecting bracket is more central in the left and right directions, which can reduce the risk of jamming.

[0046] Specifically, the height adjustment drive mechanism includes a height adjustment motor 10 hinged to the base plate 1 and a height adjustment lead screw 31 driven to rotate by the height adjustment motor 10. A first mounting base 27 is fixed on the base plate 1, and the height adjustment motor 10 is hinged to the first mounting base 27 via a first pin 28. A rotatable height adjustment block 8 is installed at the center of the linkage seat 5 in the left-right direction. The height adjustment lead screw 31 passes through the height adjustment block 8 and is threadedly engaged with the height adjustment block 8. The rotation axis of the height adjustment block 8 and the hinge axis of the height adjustment motor 10 (i.e., the axis of the first pin 28) both extend in the left-right direction.

[0047] As shown in Figure 8, the height-adjusting rotating block 8 includes a first connecting part and first mounting parts located at the left and right ends of the first connecting part. The first connecting part is provided with a first threaded hole that engages with the height-adjusting lead screw 31. A pair of first clamping blocks 9 are fixed on the linkage seat 5. The first mounting parts at both ends of the height-adjusting rotating block 8 are respectively located between the pair of first clamping blocks 9 and the linkage seat 5. The first mounting parts are rotated and engaged with the first clamping blocks 9 and with the linkage seat 5 through arc surfaces, which facilitates the rotational installation of the height-adjusting rotating block 8 and simplifies the structure.

[0048] Meanwhile, the linkage seat 5 and the base have a left guide engagement point and a right guide engagement point. In this embodiment, the connection part between the height adjustment drive mechanism and the linkage seat 5 is located in the middle of the left guide engagement point and the right guide engagement point in the left-right direction. In this way, as long as the height adjustment drive mechanism is connected to the middle position in the left-right direction of the linkage seat 5, it can ensure that the force on the linkage seat 5 is centered in the left-right direction, and thus the force transmitted to the connecting bracket is also centered in the left-right direction, ensuring smooth movement of the linkage seat 5 and the connecting bracket.

[0049] Specifically, the left guide mating point and the right guide mating point are located on the left and right guide plates 2-1 respectively, as shown in Figures 6, 8 and 9. The two linkage side walls 5-2 are respectively provided with vertically extending first grooves 5-5 on the wall surfaces opposite to the two guide plates 2-1, and the two guide plates 2-1 are respectively provided with vertically extending second grooves 2-3 on the wall surfaces opposite to the linkage side walls 5-2. The first grooves 5-5 and the second grooves 2-3 are arranged opposite to each other, and the grooves are provided with ball bearings 26 that are adapted to the groove width. This can realize the vertical guidance between the linkage seat 5 and the guide plate 2-1, reduce the friction when the two move relative to each other, and determine the limit position of the vertical movement of the linkage seat 5.

[0050] As shown in Figures 3 to 6, the aforementioned hinge component includes a hinge shaft passing through the guide plate 2-1, connecting arm 3-1, and hinge arm 5-3, and a guide sleeve 25 sleeved on the hinge shaft. In this embodiment, a bolt 24 is used as the hinge shaft. The through holes on the guide plate 2-1 and connecting arm 3-1 are smooth holes, while the through hole on the hinge arm 5-3 is a threaded hole. The bolt 24 mates with the threaded hole on the hinge arm 5-3, making assembly more convenient. Of course, in other embodiments, the through holes on the guide plate 2-1, connecting arm 3-1, and hinge arm 5-3 can all be smooth holes, with the bolt 24 passing through all three before installing the nut. The through hole on the guide plate 2-1 through which the bolt 24 passes is a second elongated hole 2-2 extending vertically, and the guide sleeve 25 contacts and mates with the wall of the second elongated hole 2-2.

[0051] An angle adjustment drive mechanism is connected between the linkage seat 5 and the mounting bracket 4 for driving the connecting seat 3 and the mounting bracket 4 to swing back and forth around the bolt 24, as shown in Figures 1, 2 and 4. The angle adjustment drive mechanism includes an angle adjustment motor 12 that is hinged to the mounting bracket 4 and an angle adjustment screw 13 that is driven to rotate by the angle adjustment motor 12. A second mounting seat 29 is fixed on the mounting bracket 4, and the angle adjustment motor 12 is hinged to the second mounting seat 29 through a second pin 30.

[0052] As shown in Figures 8 and 9, a hinge seat 5-4 is provided in the middle of the linkage seat 5 in the left-right direction and on the side opposite to the height adjustment rotating block 8. A rotatable angle adjustment rotating block 6 is installed on the hinge seat 5-4. The angle adjustment screw 13 passes through the angle adjustment rotating block 6 and is threadedly engaged with the angle adjustment rotating block 6. The rotation axis of the angle adjustment rotating block 6 and the hinge axis of the angle adjustment motor 12 (i.e., the axis of the second pin 30) both extend in the left-right direction.

[0053] The angle adjusting rotating block 6 has the same structure as the height adjusting rotating block 8. Referring to Figures 9 and 10, the angle adjusting rotating block 6 includes a second connecting part 6-1 and second mounting parts 6-3 located at both ends of the second connecting part 6-1. The second connecting part 6-1 has a second threaded hole 6-2 that threadedly engages with the angle adjusting screw 13. A pair of second clamping blocks 7 are fixed on the hinge seat 5-4. The second mounting parts 6-3 at both ends of the angle adjusting rotating block 6 are respectively located between the pair of second clamping blocks 7 and the hinge seat 5-4. The second mounting parts 6-3 and the second clamping blocks 7, as well as the second mounting parts 6-3 and the hinge seat 5-4, are all rotated through arc surfaces. This facilitates the rotational installation of the angle adjusting rotating block 6 and simplifies the structure.

[0054] As shown in Figures 1 to 5, the left and right sides of the base plate 1 are respectively provided with first bending edges 1-1, and each first bending edge 1-1 is connected to a static locking plate 11. The left and right sides of the mounting bracket 4 are provided with movable locking plates 4-1 located between the two static locking plates 11. The movable locking plates 4-1 on both sides are equipped with pneumatic locking support devices that can press and fix the movable locking plates 4-1 onto the corresponding static locking plates 11 and can release the pressure after air is supplied. The working principle of the pneumatic locking support device is similar to the cylinder elastic pressing assembly disclosed in patent CN110466353B. It mainly includes a mounting shaft 15, a cylinder 16, a first pushing sleeve 17, and a second pushing sleeve 20. The mounting shaft 15 passes through the movable locking plate 4-1 and the static locking plate 11. The two ends of the mounting shaft 15 that pass through the static locking plate 11 are respectively fitted with pads 18 and fixed nuts 19. The first push sleeve 17 is fitted onto the mounting shaft 15 and located between one side of the cylinder 16 and the movable locking plate 4-1. The second push sleeve 20 is fitted onto the mounting shaft 15 and located between the other side of the cylinder 16 and the movable locking plate 4-1. The second push sleeve 20 includes a threaded section, on which an adjusting nut 21 and a locking nut 22 are installed. A spring is installed inside the cylinder 16. When air is not supplied, the first push sleeve 17 and the adjusting nut 21, under the action of the spring, respectively press against the movable locking plates 4-1 on both sides, pressing and fixing the mounting bracket 4 onto the stationary locking plate 11. After air is supplied, the first push sleeve 17 and the adjusting nut 21 are released from pressure, and the mounting bracket 4 can move relative to the base plate 1.

[0055] As shown in Figures 1 and 3, the through hole on the static locking plate 11 for the mounting shaft 15 to pass through is a first elongated hole 11-1 extending vertically. There is a sufficient fit clearance between the mounting shaft 15 and the first elongated hole 11-1. This fit clearance allows the connecting seat 3 and the mounting bracket 4 to swing back and forth around the bolt 24.

[0056] The working principle of the instrument panel assembly adjustment structure in this application is as follows: During use, when it is necessary to adjust the vertical height of the steering column and instrument panel, firstly, air is supplied to the cylinder 16 to release the lock on the mounting bracket 4. Then, the height adjustment motor 10 is turned on, driving the height adjustment screw 31 to rotate. Under the action of the screw and nut mechanism, the height adjustment rotating block 8 moves up and down along the height adjustment screw 31, thereby driving the linkage seat 5, connecting seat 3, and mounting bracket 4 to move up and down, thus achieving height adjustment of the steering column and instrument panel. During the adjustment process, the second elongated hole 2-2 on the guide plate 2-1 and the ball bearing 26 between the linkage seat 5 and the guide plate 2-1 guide the vertical movement of the linkage seat 5, connecting seat 3, and mounting bracket 4. After the adjustment is complete, the height adjustment motor 10 stops working, and the cylinder 16 stops supplying air. The pneumatic locking support device presses the moving locking plates 4-1 on both sides, thus fixing the position of the steering column and instrument panel.

[0057] When adjusting the forward and backward angles of the steering column and instrument panel, first, air is supplied to the cylinder 16 to release the lock on the mounting bracket 4. Then, the angle adjustment motor 12 is turned on, driving the angle adjustment screw 13 to rotate. Under the action of the screw and nut mechanism, the angle adjustment rotating block 6 moves linearly along the angle adjustment screw 13, thereby pulling or pushing the mounting bracket 4 and the connecting seat 3 to swing back and forth around the bolt 24, thus achieving angle adjustment of the steering column and instrument panel. The clearance between the mounting shaft 15 and the first elongated hole 11-1 is sufficient to meet the swing stroke requirements of the mounting bracket 4 and the connecting seat 3. After adjustment, the angle adjustment motor 12 stops working, and the cylinder 16 stops supplying air. The pneumatic locking support device presses the moving locking plates 4-1 on both sides, fixing the position of the steering column and instrument panel.

[0058] During height adjustment, since the linkage seat 5 is in the middle, the force-bearing part of the linkage seat 5 is in the exact center of the left-right direction. The force on the linkage seat 5 is evenly transmitted to the connecting seat 3, making the force on the connecting seat 3 more central and reducing the risk of jamming. Furthermore, during angle adjustment, since the angle adjustment drive mechanism has only one output end, the angle adjustment screw 13 only needs to be connected to one linkage seat 5, simplifying the connection structure and the structure of the angle adjustment drive mechanism. Therefore, configuration costs can be reduced and assembly operations simplified. Additionally, the connection position between the angle adjustment screw 13 and the linkage seat 5 is not exactly in the exact center of the left-right direction of the linkage seat 5, but slightly offset, yet still in the middle. This is because the weight of the instrument panel is not balanced left-right. Therefore, the angle adjustment motor 12 and the angle adjustment screw 13 are positioned towards the heavier side, which can better drive the instrument panel to swing back and forth.

[0059] In other embodiments of the instrument panel assembly adjustment structure: the first bending edge may not be provided on the base plate, and the base plate is directly fixedly connected to the vehicle body. In this case, the connection structure on the base plate is the connection hole opened on the base plate.

[0060] In other embodiments of the instrument panel assembly adjustment structure: the base can be a one-piece cast part, in which case the base plate and the fixed seat are integrally connected.

[0061] In other embodiments of the instrument panel assembly adjustment structure: the connecting bracket can also be integrally stamped and bent from sheet metal, instead of being composed of separate connecting seats and mounting brackets.

[0062] In other embodiments of the instrument panel assembly adjustment structure: the hinge shaft in the hinge component can also be replaced with a pin. In this case, retaining rings or cotter pins need to be installed at both ends of the pin to prevent the pin from falling off. In other embodiments, regardless of whether a bolt or a pin is used as the hinge shaft, the sleeve is no longer required on the hinge shaft. In this case, the hinge shaft directly engages with the elongated hole on the guide plate.

[0063] In other embodiments of the instrument panel assembly adjustment structure: the guiding fit between the linkage seat and the guide plate may not be a groove and ball bearing, but rather a guide elongated hole is opened on the guide plate, and a pin is connected to the linkage seat. The pin passes through the guide elongated hole to achieve a guiding fit with the base. At this time, the left guide fit point and the right guide fit point are still located on the left and right guide plates.

[0064] In other embodiments of the instrument panel assembly adjustment structure: the left guide mating point and the right guide mating point may not be on the left and right guide plates. For example, a guide rod extending vertically is fixed separately on the base plate. The guide rod passes through the linkage seat and can guide the vertical movement of the linkage seat.

[0065] In other embodiments of the instrument panel assembly adjustment structure: the connection between the height adjustment drive mechanism and the linkage seat is located in the middle of the left guide mating point and the right guide mating point in the left-right direction, rather than in the exact center. Of course, in other embodiments, it can also be slightly off-center. Compared with the complete offset in the prior art, it can also improve the jamming situation of the connecting bracket.

[0066] In other embodiments of the instrument panel assembly adjustment structure: the connection point between the height adjustment drive mechanism and the linkage seat may not be exactly in the middle of the linkage seat in the left-right direction, but may be slightly offset, but still in the middle. Compared with the complete offset in the prior art, this can still improve the stress effect of the connecting bracket.

[0067] In other embodiments of the instrument panel assembly adjustment structure: the pneumatic locking support device may not be required. The connecting bracket can be kept in a predetermined position by the self-locking action between the angle adjusting screw and the angle adjusting rotating block, and between the height adjusting screw and the height adjusting rotating block, after the height adjusting motor and the angle adjusting motor stop working. In this case, there is no need to install a static locking plate.

[0068] In other embodiments of the instrument panel assembly adjustment structure: the rotational installation method of the height adjustment rotating block and the angle adjustment rotating block can be to fix two ear plates on the linkage seat. The two ear plates are provided with mounting holes for the end of the rotating block to extend into. The mounting holes are complete circular holes. One ear plate is fixed on the linkage seat in advance. After one end of the rotating block extends into the circular hole on the ear plate, the other ear plate is installed and the other end of the rotating block extends into the circular hole of the ear plate. Of course, there is a rotational fit clearance between both ends of the rotating block and the circular hole.

[0069] In other embodiments of the instrument panel assembly adjustment structure: the angle adjustment drive mechanism can also be a drive mechanism that outputs telescopic action, such as an electric push rod, hydraulic cylinder or pneumatic cylinder. In this case, the telescopic rod of the drive mechanism is directly hinged to the linkage seat, or conversely, the cylinder body of the drive mechanism is hinged to the linkage seat, and the telescopic rod is hinged to the connecting bracket.

[0070] In other embodiments of the instrument panel assembly adjustment structure: the height adjustment drive mechanism can also be a drive mechanism that outputs telescopic action, such as an electric push rod, hydraulic cylinder or pneumatic cylinder. In this case, the telescopic rod of the drive mechanism is directly hinged to the linkage seat, or conversely, the cylinder body of the drive mechanism is hinged to the linkage seat, and the telescopic rod is hinged to the base.

[0071] In other embodiments of the instrument panel assembly adjustment structure: the guiding engagement between the hinge component and the guide plate can also be achieved by providing vertically extending grooves on the guide plate, with the end of the hinge component extending into the grooves and engaging with them in a guiding engagement.

[0072] The embodiment of the instrument panel assembly in this application is as follows: The instrument panel assembly includes an instrument panel, a steering column, and an adjustment structure for adjusting the height and front-rear angle of the instrument panel and the steering column. The adjustment structure is the same as the adjustment structure of the instrument panel assembly in any of the above embodiments, and will not be repeated here.

[0073] The vehicle embodiment in this application is as follows: the vehicle includes a vehicle body and an instrument panel assembly mounted on the vehicle body. The instrument panel assembly includes an instrument panel, a steering column, and an adjustment structure for adjusting the height and front-rear angle of the instrument panel and the steering column. The adjustment structure is the same as the instrument panel assembly adjustment structure in any of the above embodiments, and will not be repeated here.
