Description

Technical Field

[0001] The utility model relates to a dashboard for a vehicle, in particular to the arrangement of accessories on the dashboard. Background Art

[0002] The instrument panel assembly usually includes an instrument panel, a steering wheel and a steering column. With the development of public transportation digitization and intelligence, the current mainstream domestic passenger cars have the function of adjusting the instrument panel assembly. For example, the Chinese utility model patent with the authorization announcement number CN209814106U discloses an instrument panel linkage mechanism, which includes a fixed bracket, a steering column and an instrument panel bracket. The instrument panel bracket is fixedly connected to the steering column, and the instrument panel bracket is connected to the fixed bracket through a first locking mechanism, and the steering column is connected to the fixed bracket through a second locking mechanism. When adjusting, the first locking mechanism releases the instrument panel bracket, the second locking mechanism releases the steering column, and the steering column is moved to move, so that the instrument panel bracket and the steering column move together, and the up and down height and front and back angle of the steering wheel and the instrument panel can be adjusted.

[0003] However, the above adjustment method is manual movement, which is laborious to adjust. Therefore, an automatic adjustment method has also appeared in the prior art. For example, the Chinese invention patent application with publication number CN110356229A discloses an automatic adjustment mechanism and method for a vehicle instrument panel, wherein the automatic adjustment mechanism includes a base connected to the vehicle body, a connecting member rotatably connected to the base and used to install the instrument panel and the steering wheel, and an electric adjustment device that drives the connecting member to move relative to the base. The electric adjustment device includes an upper push rod assembly and a lower push rod assembly. The upper push rod assembly includes two upper electric push rods, and the lower push rod assembly includes two lower electric push rods. The two upper electric push rods are respectively located on the left and right sides of the base, and the lower ends are fixed to the base, and the upper ends are rotatably connected to the instrument panel bracket. The two lower electric push rods are respectively located on the left and right sides of the base, and the lower ends are fixed to the base, and the upper ends are rotatably connected to the steering column bracket. During adjustment, the upper and lower heights of the instrument panel and the steering wheel can be adjusted by extending and retracting the upper and lower electric push rods at the same speed and synchronously. When the extension and retraction degrees of the upper and lower electric push rods are inconsistent, the instrument panel and the steering wheel perform a compound movement of lifting and swinging. Of course, if the lower electric push rod does not extend or retract, only the upper electric push rod extends or retracts, the instrument panel and the steering wheel can be swung to adjust the angle.

[0004] The above-mentioned automatic adjustment mechanism uses four electric push rods to adjust the position of the instrument panel and the steering wheel, wherein the two upper electric push rods and the two lower electric push rods are arranged on the left and right sides of the base. The two upper electric push rods need to extend and retract synchronously at the same speed, and the two lower electric push rods also need to extend and retract synchronously at the same speed, otherwise the mechanism will fail. This not only has a complex structure, but also has high control requirements, which increases the difficulty of control. Utility Model Content

[0028] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0029] In view of the technical problems existing in the prior art, the basic technical concept of the present utility model is to reduce the number of upper telescopic power devices and lower telescopic power devices, and to provide only one of each, thereby simplifying the structure. At the same time, the upper telescopic power device and the lower telescopic power device are arranged in the center, so that the height and angle of the instrument panel assembly can be smoothly adjusted by an upper telescopic power device and a lower telescopic power device. When adjusting the height, a total of two power devices need to be controlled to move synchronously, and when adjusting the angle, only one power device needs to be controlled to work, which greatly reduces the control difficulty compared to the prior art.

[0030] Embodiment of the instrument panel assembly adjustment structure in the utility model:

[0031] like Figure 1 , Figure 3 , Figure 4 As shown, the instrument panel assembly includes an instrument panel 1, a steering wheel 2 and a steering column 3. The instrument panel assembly adjustment structure includes a base for fixedly connecting to the vehicle body and a connecting bracket for connecting the instrument panel assembly. An upper telescopic power device and a lower telescopic power device are connected between the base and the connecting bracket. The telescopic ends are arranged up and down and are used to adjust the height and angle of the instrument panel assembly. In this embodiment, the upper telescopic power device is an upper electric push rod 6, and the lower telescopic power device is a lower electric push rod 7. The telescopic ends of the upper electric push rod 6 and the lower electric push rod 7 are arranged up and down, and only one upper electric push rod 6 and one lower electric push rod 7 are respectively provided.

[0032] Specifically, the connecting bracket in this embodiment includes a connecting seat 15 for fixedly connecting with the steering column 3. Figure 4 , Figure 5 and Figure 6 As shown, the connection seat 15 is sleeved and fixed on the outside of the steering column 3 in the form of a hoop, and the left and right sides of the connection seat 15 are respectively fixed with connection plates 16, and the connection plates 16 are installed with bearings 20 for matching with the upper and lower guides of the base. A connection rod 15-1 extending downward is provided on the connection seat 15, and the telescopic end of the lower electric push rod 7 is located between the left and right two connection plates 16. The telescopic end of the lower electric push rod 7 is hinged with the connection rod 15-1, and the hinge axis extends in the left and right directions and is coaxial with the rotation axis of the bearing 20. The use of the bearing 20 for guidance can reduce the friction when the instrument panel assembly moves up and down. At the same time, since the relative positions of the connection seat 15 and the connection plate 16 are fixed, that is, the relative positions of the connection rod 15-1 and the bearing 20 are fixed, the hinge axis of the lower electric push rod 7 and the connection rod 15-1 is always coaxial with the rotation axis of the bearing 20. In this way, when the lower electric push rod 7 does not move and only the upper electric push rod 6 is telescopic, it is convenient for the instrument panel assembly to swing forward and backward around the rotation axis of the bearing 20, thereby adjusting the angle.

[0033] In addition, the connecting bracket also includes an instrument panel bracket 13 for fixedly connecting to the instrument panel 1, and the connecting seat 15 is also provided with a connecting column 15-2 fixedly connected to the middle part of the instrument panel bracket 13, so as to achieve relative fixation between the steering wheel 2, the steering column 3 and the instrument panel 1. Figure 3 and Figure 6 As shown, a mounting seat 14 is fixed in the middle of the instrument panel bracket 13, and the telescopic end of the upper electric push rod 6 is hinged to the mounting seat 14, and the hinge axis extends in the left-right direction. Since the hinge position of the upper electric push rod 6 and the instrument panel bracket 13 is located in the middle of the instrument panel bracket 13, the connection position of the upper electric push rod 6 and the connecting bracket is located in the middle of the connecting bracket in the left-right direction. At the same time, since the connecting seat 15 is fixedly connected to the steering column 3, the connecting seat 15 is located in the middle of the connecting bracket in the left-right direction relative to the entire connecting bracket, thereby realizing that the connection position of the lower electric push rod 7 and the connecting bracket is located in the middle of the connecting bracket in the left-right direction.

[0034] like Figure 1 , Figure 4 and Figure 7 As shown, the base includes an upper bracket 4 and a lower bracket 5, combined with Figure 2 and Fig. 9 As shown, the upper bracket 4 includes an upper middle plate 4-1 and upper side plates 4-2 connected to the left and right sides of the upper middle plate 4-1 and extending upwards respectively. Figure 2 and Figure 8As shown, the lower bracket 5 includes a lower middle plate 5-1 and lower side plates 5-2 connected to the left and right sides of the lower middle plate 5-1 and extending downward respectively. The upper middle plate 4-1 and the lower middle plate 5-1 are attached and fixedly connected, and the specific fixed connection method is bolt connection, wherein the upper electric push rod 6 is connected to the upper middle plate 4-1, and the lower electric push rod 7 is connected to the lower middle plate 5-1, thereby realizing that the connection positions of the upper electric push rod 6 and the lower electric push rod 7 with the base are both located in the middle of the left and right directions of the base. At the same time, the base is configured to include an upper bracket 4 and a lower bracket 5, and the upper middle plate 4-1 and the lower middle plate 5-1 are fixedly connected, and the two electric push rods are respectively connected to a middle plate, which not only realizes the upper and lower arrangement of the telescopic ends of the two electric push rods, but also facilitates the processing and manufacturing of the base, and facilitates the connection and coordination between the upper side plate 4-2 and the lower side plate 5-2 and other components.

[0035] Furthermore, if Figure 2 As shown, the upper electric push rod 6 is hinged to the upper middle plate 4-1 through the upper hinge seat 8, and the lower electric push rod 7 is hinged to the lower middle plate 5-1 through the lower hinge seat 9. The upper hinge seat 8 is fixed to the upper side surface of the upper middle plate 4-1 by bolts (first bolts 10) passing through the upper middle plate 4-1 and the lower middle plate 5-1, and the lower hinge seat 9 is fixed to the lower side surface of the lower middle plate 5-1 by bolts (second bolts 11) passing through the upper middle plate 4-1 and the lower middle plate 5-1. Therefore, the bolts that fix the upper and lower hinge seats are also the bolts that realize the fixed connection between the upper middle plate 4-1 and the lower middle plate 5-1. Moreover, in the present embodiment, the upper hinge seat 8 and the lower hinge seat 9 are arranged on the left and right and have overlapping parts in the up and down directions. The overlapping parts are fixedly connected to the upper middle plate 4-1 and the lower middle plate 5-1 by common bolts (common bolts 12). In this way, on the basis of realizing the installation of the upper and lower hinge seats and the fixation of the upper middle plate 4-1 and the lower middle plate 5-1, the number of bolts can be saved, and the installation operation is convenient. At the same time, the upper electric push rod 6 and the lower electric push rod 7 are arranged on the left and right and as close as possible, each closer to the center line of the connecting bracket in the left and right directions, ensuring that the force applied to the connecting bracket is more centered, making the movement of the connecting bracket more stable.

[0036] To facilitate the installation of bolts, Fig. 9 As shown, a first fixing hole 4-4 and a second fixing hole 4-5 are provided on the upper middle plate 4-1. Figure 8As shown, a fourth fixing hole 5-5 and a fifth fixing hole 5-6 are provided on the lower middle plate 5-1. The fourth fixing hole 5-5 corresponds to the first fixing hole 4-4 and two are provided respectively to install a set of bolts. The fifth fixing hole 5-6 corresponds to the second fixing hole 4-5 and three are provided respectively to install the first bolt 10, the second bolt 11 and the common bolt 12. In addition, an upper through hole 4-3 is provided on the upper middle plate 4-1 for the housings of the upper electric push rod 6 and the lower electric push rod 7 to pass through respectively, and a lower through hole 5-4 is provided on the lower middle plate 5-1 for the housings of the upper electric push rod 6 and the lower electric push rod 7 to pass through respectively. The upper through hole 4-3 and the lower through hole 5-4 are equal in size and together constitute Figure 7 The through hole 21 shown in FIG. By passing the housings of the upper electric push rod 6 and the lower electric push rod 7 through the through hole 21, the arrangement of the upper electric push rod 6 and the lower electric push rod 7 can be facilitated, and there is no need to make the hinge seat very high in order to avoid the middle plate, thereby reducing the volume of the hinge seat and facilitating installation and arrangement.

[0037] In the present invention, the instrument panel assembly adjustment structure also includes a locking cylinder for locking the position of the connecting bracket, such as Figure 1 to Figure 6 As shown, the locking cylinder includes an upper locking cylinder 18 and a lower locking cylinder 19. The locking principle belongs to the prior art and will not be described in detail in the present utility model. It should be noted that the lower locking cylinder 19 has a support rod, such as Figure 8 As shown, a guide hole 5-3 is provided on the lower side plate 5-2, and the support rod passes through the arc-shaped long hole and the guide hole 5-3 on the connecting plate 16 in sequence, guiding the locking cylinder 19 when it moves up and down driven by the connecting bracket, and at the same time, it will not interfere with the connecting bracket when it swings back and forth.

[0038] like Figure 4 and Figure 7 As shown, the base also includes a guide bracket 17 fixedly connected to the upper bracket 4 and the lower bracket 5, Fig.10 As shown, the guide bracket 17 includes guide plates 17-2 on the left and right sides and a first fixing plate 17-1 connected between the guide plates 17-2 on both sides. The guide plates 17-2 have guide grooves, and the bearings 20 mentioned above are embedded in the guide grooves, so as to guide the up and down movement of the connecting bracket, while not affecting the forward and backward swinging of the connecting bracket relative to the guide plates 17-2. In order to ensure the fixing effect, the sixth fixing hole 17-4 and the seventh fixing hole 17-5 are provided on the first fixing plate 17-1, wherein the sixth fixing hole 17-4 is correspondingly connected to the first fixing hole 4-4 and the fourth fixing hole 5-5 mentioned above, and the upper bracket 4, the lower bracket 5 and the guide bracket 17 are fixed by installing a set of bolts. As shown Fig. 9As shown, the upper bracket 4 is also provided with a third fixing hole 4-6, and the seventh fixing hole 17-5 is correspondingly connected to the third fixing hole 4-6, and the upper bracket 4 and the guide bracket 17 are fixed by a set of bolts. In addition, the lower part of each guide plate 17-2 is connected to a second fixing plate 17-3 ( Fig.10 As shown, a plurality of fixing holes are provided on the second fixing plate 17-3, and a plurality of fixing columns 5-7 ( Figure 8 As shown), the fixing column 5-7 passes through the fixing hole on the second fixing plate 17-3 to prevent the guide plate 17-2 from moving relative to the lower bracket 5.

[0039] like Figure 1 As shown, the instrument panel assembly adjustment structure also includes a control unit 22 that is connected to the corresponding solenoid valves of the upper locking cylinder 18 and the lower locking cylinder 19. The control unit 22 is also connected to the upper electric push rod 6 and the lower electric push rod 7. The control unit 22 can transmit external electric energy to the upper electric push rod 6 and the lower electric push rod 7, and can receive signal feedback from the upper electric push rod 6 and the lower electric push rod 7. The instrument panel assembly adjustment structure also includes a switch unit 23 connected to the control unit 22. The switch unit 23 has a setting key (i.e., SET key), up and down keys, and left and right keys. The SET key is located between the up and down keys and the left and right keys. The on and off of the gas source of the upper locking cylinder 18 and the lower locking cylinder 19 can be controlled by the SET key of the switch unit 23; the forward and reverse control of the upper electric push rod 6 and the lower electric push rod 7 can be realized simultaneously by the up and down keys of the switch unit 23, thereby realizing the up and down position adjustment of the instrument panel assembly; the forward and reverse control of the upper electric push rod 6 can be realized separately by the left and right keys of the switch unit 23, thereby realizing the angle adjustment of the instrument panel assembly.

[0040] The specific adjustment process is:

[0041] When adjusting the height up and down, press the SET button of the switch unit 23, the upper locking cylinder 18 and the lower locking cylinder 19 are ventilated, and the lock on the connecting bracket is released. Press the upper button or the lower button of the switch unit 23, and the upper electric push rod 6 and the lower electric push rod 7 extend or shorten at the same time, driving the instrument panel assembly to move up or down; press the SET button of the switch unit 23 again, or the switch unit 23 does not move within 5 seconds, the upper locking cylinder 18 and the lower locking cylinder 19 are automatically de-energized, and the connecting bracket and the instrument panel assembly are locked.

[0042] When adjusting the front and rear angles, press the SET button of the switch unit 23, the upper locking cylinder 18 and the lower locking cylinder 19 are ventilated, the lock on the connecting bracket is released, and the left or right button of the switch unit 23 is pressed, the upper electric push rod 6 extends or shortens, driving the instrument panel assembly to swing forward and backward; press the SET button of the switch unit 23 again, or the switch unit 23 does not move within 5 seconds, the upper locking cylinder 18 and the lower locking cylinder 19 are automatically de-energized, and the connecting bracket and the instrument panel assembly are locked.

[0043] In addition, the switch unit is also provided with a memory key for extracting the set position of the instrument panel assembly so that the control unit 22 can directly control the upper electric push rod 6 and the lower electric push rod 7 to rotate forward and reverse a corresponding number of times. There are three memory keys in this embodiment. After pressing the corresponding memory key, the instrument panel assembly moves directly to the corresponding position, which is quick and convenient.

[0044] In summary, the utility model uses an upper electric push rod 6 and a lower electric push rod 7 to adjust the height and angle of the instrument panel assembly, which simplifies the structural setting. If the height is adjusted, it is only necessary to control the two electric push rods to extend and retract synchronously and at the same speed. If the angle is adjusted, it is only necessary to control the extension and retraction of one electric push rod. Compared with the prior art, the number of control components is reduced, which can reduce the control difficulty. In addition, the two electric push rods are arranged in the center as much as possible to ensure the smooth movement of the instrument panel assembly.

[0045] In other implementations of the instrument panel assembly adjustment structure: the memory keys on the switch unit may be set to one, two, four or more. Of course, no memory keys may be set. Different drivers may readjust the driving according to their own circumstances.

[0046] In other embodiments of the instrument panel assembly adjustment structure: the switch that controls the on and off of the locking cylinder air source can be set separately and not integrated on the switch unit. Of course, the switch that controls the forward and reverse rotation of the upper electric push rod and the lower electric push rod at the same time and the switch that controls the forward and reverse rotation of the upper electric push rod alone can also be set separately and do not need to be integrated on one switch unit.

[0047] In other embodiments of the instrument panel assembly adjustment structure: the upper telescopic power device and the lower telescopic power device can also be a cylinder or a hydraulic cylinder, and a solenoid valve is provided in the pipeline of the cylinder or the hydraulic cylinder. In this case, there is no need to set a control unit and a switch unit, but only a button to control the operation of the corresponding solenoid valve can be provided.

[0048] In other embodiments of the instrument panel assembly adjustment structure: a connecting column may not be provided on the connecting seat fixed to the steering column, but a fixing hole may be directly provided on the end face of the connecting seat and fixedly connected to the instrument panel bracket by bolts.

[0049] In other embodiments of the instrument panel assembly adjustment structure: the telescopic end of the upper telescopic power device may not be hinged to the instrument panel bracket. For example, a fixed plate is fixed on a connecting plate connected to the connecting seat, and the telescopic end of the upper telescopic power device may be hinged to the fixed plate.

[0050] In other embodiments of the instrument panel assembly adjustment structure: the telescopic end of the lower telescopic power device may not be hinged to the connecting rod on the connecting seat, but a fixed rod may be fixed between the two connecting plates, and the telescopic end of the lower telescopic power device may be hinged to the fixed rod. Of course, in other embodiments, the fixed shaft on which the bearing is installed may extend between the left and right connecting plates, and the telescopic end of the lower telescopic power device may be directly hinged to the fixed shaft.

[0051] In other embodiments of the instrument panel assembly adjustment structure: instead of installing the bearing on the connecting plate, a round shaft may be directly fixed, and a through hole for the round shaft to pass through is provided on the guide bracket or the lower bracket, and the through hole is a long hole to guide the connecting bracket.

[0052] In other implementations of the instrument panel assembly adjustment structure: the guide bracket can be fixed only to the upper bracket, and of course the guide bracket can also be fixed only to the lower bracket.

[0053] In other embodiments of the instrument panel assembly adjustment structure: by setting the upper hinge seat and the lower hinge seat higher, it can be ensured that the upper telescopic power device and its shell do not contact the upper middle plate, and the shell of the lower telescopic power device does not contact the lower middle plate. At this time, there is no need to set perforations on the upper middle plate and the lower middle plate.

[0054] In other embodiments of the instrument panel assembly adjustment structure: when the upper articulated seat and the lower articulated seat are of appropriate sizes and the shells of the upper telescopic power device and the lower telescopic power device will not interfere with the middle plate, the upper articulated seat and the lower articulated seat can be aligned vertically. At this time, the upper telescopic power device and the lower telescopic power device are also aligned vertically and are both located on the center line in the left and right directions of the base, realizing a truly centered arrangement. At this time, for the convenience of installation, the upper articulated seat and the lower articulated seat can be fixed to the upper middle plate and the lower middle plate by common bolts.

[0055] In other embodiments of the instrument panel assembly adjustment structure: the shell of the upper telescopic power device can be fixedly connected to the upper middle plate, and the shell of the lower telescopic power device is fixedly connected to the lower middle plate. At this time, in order to avoid affecting the smooth rotation of the connecting bracket, the hinge hole through which the connecting bracket is hingedly connected to the telescopic end of the upper telescopic power device is an arc-shaped long hole. At this time, since the shells of the upper and lower telescopic power devices are fixed to the base, there is no need to set an additional guide structure for the up and down movement of the connecting bracket.

[0056] In other embodiments of the instrument panel assembly adjustment structure: the base can be formed by casting in one piece, which is equivalent to an integral plate in which the upper middle plate and the lower middle plate are integrally connected, and at this time, the upper and lower telescopic power devices are both connected to the integral plate.

[0057] In other embodiments of the instrument panel assembly adjustment structure: according to specific needs, when there is no need to guide the connecting bracket and the instrument panel assembly adjustment structure does not include a locking cylinder, the lower bracket may not be provided, and at this time both the upper and lower telescopic power devices are connected to the upper bracket.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the description and drawings of the present invention shall be included in the protection scope of the present invention.
