DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] At present, the central control screen is an important display, operation and audio-visual entertainment component on the vehicle. Usually, the central control screen is set on the side of the dashboard close to the driver or in the center of the dashboard, and is mainly used by the driver and passengers. As the co-pilot's demand for audio-visual entertainment becomes more and more important and the proportion of use increases, the above setting position of the central control screen will cause interference to the driver when the co-pilot uses the central control screen. At the same time, because the central control screen is not directly in front of the co-pilot, the co-pilot's operating convenience experience is also poor.

[0032] In view of the above problems, there is a sliding mechanism for a large in-vehicle central control screen in the prior art, which includes a fixed frame, a slide rail mounting base mounted on the fixed frame, a slider located in the slide rail mounting base and slidingly matched with the mounting base through two slide bars, a screw threadedly connected to the slider in the slider, and the central control screen is connected to the bracket, the fixed seat and the slider in sequence. Its working principle is: the motor drives the screw rod to rotate, thereby driving the slider and the central control screen to slide in turn, thereby adjusting the central control screen to a suitable position, so that the central control screen is operable; at the same time, in order to improve the structural stability, the sliding mechanism for the large in-vehicle central control screen further constrains the bracket to slide through the upper decorative plate.

[0033] In the above-mentioned sliding mechanism for the vehicle-mounted central control large screen, since a large assembly gap is provided between the slide rail mounting base and the fixed frame, and the two slide bars and the transverse screw holes are arranged on the slider, the slider not only has to realize the function of driving the bracket to slide, but also has to form a sliding constraint with the slide rail mounting base. Therefore, after long-term use, the above-mentioned sliding mechanism is prone to jamming and has a short service life. At the same time, since the upper decorative panel is a plate-like structure, it is easy to deform (subject to the lateral force of the bracket), so the above-mentioned structural stability is relatively low.

[0034] In view of the above problems, there is also a sliding mechanism in the prior art that can drive the central control screen 7 to move in parallel. The sliding mechanism usually drives the central control screen to slide through a slider assembly 4 that can move in parallel. The sliding assembly and the central control screen 7 are driven to slide along the axial direction of the screw rod 32 in turn through the screw rod 32 inside the box body, and the sliding assembly is limited by two guide rods passing through the sliding assembly, thereby realizing the sliding constraint of the central control screen in the horizontal and vertical directions. After research, it is found that the above sliding mechanism has the following problems:

[0035] 1) Since the two guide rods are inside the sliding mechanism, due to the limitations of the installation process and the internal space of the vehicle, the force arm of the two guide rods when torsion is sometimes smaller than the width of the sliding mechanism, which easily makes the structural stability of the sliding mechanism poor. Therefore, it is necessary to make improvements;

[0036] 2) Since the two guide rods need to pass through the slider assembly 4, and the two guide rails must be parallel to the screw rod 32 during installation, the manufacturing accuracy of the above sliding mechanism is very high. In actual operation, if the manufacturing accuracy of the sliding mechanism is poor and the requirement of ensuring the parallelism of the two guide rails and the screw rod 32 is not met, the above sliding mechanism is prone to jamming; at the same time, if the tolerance of the sliding mechanism is large, it is also easy to produce gap abnormal noise;

[0037] 3) Since the two guide rods not only constrain the sliding of the slider assembly 4 in the horizontal and vertical directions, but also guide the slider assembly 4, the surface accuracy quality requirements of the two guide rods are very high during actual operation. Therefore, the two guide rods are usually steel guide rods that have been processed by fine polishing, and their cost is relatively high.

[0038] In response to the above problems, Figure 1 and Fig. 9 As shown, due to the effect of gravity, the central control screen 7 will generate a large torque on the supporting cantilever of the bracket assembly 5. In order to ensure that the present invention provides sufficient supporting stiffness within the limited space inside the dashboard, and at the same time to solve the parallelism problem of installation accuracy in manufacturing accuracy (the normal assembly parallelism is 0.5mm), an embodiment of the present invention provides a lateral sliding device for a vehicle-mounted central control screen.

[0039] like Figure 1 and Figure 5 As shown, the lateral sliding device for the vehicle-mounted central control screen includes: a bearing seat 1 and a controller 2, wherein the bearing seat 1 is provided with a material discharge trough 11; a sliding drive mechanism 3, wherein the sliding drive mechanism 3 is installed on the bearing seat 1 and is electrically connected to the controller 2; a slider assembly 4, wherein the slider assembly 4 is installed at the bottom of the material discharge trough 11 and is connected to the output end of the sliding drive mechanism 3, and a lateral limiting mechanism 6 for lateral limiting of the slider assembly 4 is connected between the side wall of the material discharge trough 11 and the slider assembly 4; a bracket assembly 5, wherein the bracket assembly 5 is installed on the slider assembly 4 and is connected to the central control screen 7.

[0040] In actual operation, the bearing seat 1 is installed on the instrument panel frame or the instrument panel cross beam 91, and the controller 2 is used as a control center. It controls the working state of the sliding drive mechanism 3 to control the position of the slider assembly 4 on the bearing seat 1, thereby adjusting the position of the central control screen 7. The sliding drive mechanism 3 is used to drive the slider assembly 4 to slide on the bearing seat 1, thereby driving the bracket assembly 5 and the central control screen 7 to slide on the bearing seat 1. The bracket assembly 5 is used to slide with the slider assembly 4, and under the action of the controller 2 and the sliding drive mechanism 3, the central control screen 7 is brought to a suitable position of the vehicle, so that the occupants of the vehicle can more conveniently obtain driving information and entertainment information.

[0041] During actual operation, since the lateral limiting mechanism 6 can provide a supporting force / torque in the vertical direction (Z direction) to the bracket assembly 5 through the slider assembly 4, thereby realizing the Z direction limitation, and also provides a horizontal direction (X direction) limitation (the two first sliding limit grooves 61 are mainly used to provide supporting force / torque and limitation, and the two second sliding limit grooves 63 provide horizontal direction limitation), the driving mechanism 3 of the present invention only needs to provide a lateral driving force without bearing other additional loads. Therefore, each part of the structure of the present invention has a single load-bearing capacity, the overall reliability and durability are greatly improved, and the service life is longer.

[0042] like Figures 1 to 3 As shown, the sliding drive mechanism 3 includes a motor assembly 31 mounted on the bearing seat 1 and located outside the material discharge trough 11, and a screw rod 32 mounted on the bearing seat 1 and located inside the material discharge trough 11, and the output end of the motor assembly 31 is connected to the screw rod 32. In actual operation, the limit block 41 is sleeved on the screw rod 32 and is threadedly connected to the screw rod 32. In this way, the present invention can drive the screw rod 32 to rotate through the motor assembly 31, thereby driving the slider assembly 4, the bracket assembly 5 and the central control screen 7 to slide in turn.

[0043] Preferably, the sliding drive mechanism 3 also includes a reducer, and the output end of the motor assembly 31 is connected to the screw rod 32 through the reducer to allow the screw rod 32 to rotate at a slower speed (5 revolutions per second), thereby allowing the central control screen 7 to slide at a slower speed, thereby further increasing the structural stability of the present invention.

[0044] The present invention further comprises a box cover shell 8 mounted on the bearing seat 1, the discharge groove 11, the slider assembly 4 and the bracket assembly 5 are all located in the discharge cavity 9 formed by the box cover shell 8 and the bearing seat 1, and a sliding groove 81 for the bracket assembly 5 to slide on the bearing seat 1 is provided on the side wall of the box cover shell 8. In this way, the box cover shell 81 is fixedly connected to the bearing seat 1 to form a closed box structure, thereby further increasing the structural strength of the present invention, and further improving the structural stability of the present invention for the central control screen 7.

[0045] In actual operation, the structure composed of the bearing seat 1 and the box cover shell 8 in the present invention is collectively referred to as a box body. The first sliding limit groove 61 and the second sliding limit groove 63 on the bearing seat 1 can be collectively referred to as sliding limit grooves. The three sliding limit grooves (including two first sliding limit grooves 61 + one second sliding limit groove 63) can be manufactured by coaxial processing. At this time, the staff only needs to draw a reference line at the bottom of the discharge trough 11 for installing the screw rod 32 and parallel to the screw rod 32, and let the reference line be parallel to the above-mentioned three sliding limit grooves. Therefore, when the various components in the present invention are actually assembled, very high assembly accuracy and surface accuracy are not required.

[0046] like Figure 6 and Figure 7 As shown, the lateral limiting mechanism 6 includes a first sliding limiting groove 61 located on the side wall of the discharge trough 11, and a first sliding limiting rod 62 installed on the side of the slider assembly 4 and corresponding to the first sliding limiting groove 61. In this way, under the action of the first sliding limiting groove 61 and the first sliding limiting rod 62, the present invention can well realize the lateral limiting function of the slider assembly 4, so that the structural stability of the present invention is relatively high.

[0047] Preferably, Figure 6 and Figure 7 As shown, the lateral limiting mechanism 6 further includes a second sliding limiting groove 63 arranged at the bottom of the discharge trough 11, and a second sliding limiting rod 64 installed at the bottom of the slider assembly 4 and corresponding to the second sliding limiting groove 63. In this way, under the joint action of the first sliding limiting rod 62 and the second sliding limiting rod 64, the present invention further strengthens the lateral limiting function of the slider assembly 4, thereby making the structural stability of the present invention higher.

[0048] like Figure 4 and Figure 5As shown, the slider assembly 4 includes a limit block 41 connected to the output end of the sliding drive mechanism 3, and a sliding block 42 connected to the end of the limit block 41 away from the bearing seat 1, and the lateral limit mechanism 6 is located between the sliding block 42 and the side wall of the discharge trough 11. In this way, the present invention also realizes that the structure (limit block 41) used to cooperate with the sliding drive mechanism 3 and the structure (sliding block 42) used to cooperate with the bearing seat 1 are arranged separately, so that the present invention only needs to manufacture the limit block 41 and the sliding block 42 separately, and then assemble the above-mentioned limit block 41 and the sliding block 42 together, so that the manufacturing precision of the slider assembly 4 of the present invention is low and the cost is low.

[0049] like Figure 4 and Figure 5 As shown, the sliding block 42 includes a sliding base plate 421 connected to the limit block 41, and sliding side plates 422 connected to both ends of the sliding base plate 421; a sliding accommodating cavity 423 is formed between the sliding base plate 421 and the sliding side plates 422, the opening facing the supporting seat 1 and used to accommodate the limit block 41, and the first sliding limit rod 62 and / or the second sliding limit rod 64 are installed on the sliding side plate 422.

[0050] In this way, under the action of the sliding side plate 422, the present invention also realizes the sliding cooperation between the sliding block 42 and the bearing seat 1; under the action of the sliding bottom plate 421, the sliding side plate 422 and the sliding accommodating cavity 423, the slider assembly 4 only needs to occupy a very small space to realize the function of driving the bracket to move, thereby making the structure of the present invention more compact and occupying less space, thereby allowing the vehicle to have more material discharge space.

[0051] like Figure 5 and Figure 6 As shown, the sliding side plate 422 includes a first side plate 424 connected to one end of the sliding bottom plate 421, and a second side plate 425, a third side plate 426 and a fourth side plate 427 connected in sequence to the other end of the sliding bottom plate 421, the second side plate 425, the third side plate 426 and the fourth side plate 427 together form an opening facing away from the bearing seat 1, and form a closed-loop cavity 428 with the bracket assembly 5; the second sliding limit rod 64 is installed on the third side plate 426, and there are two first sliding limit rods 62, one of which is installed on the first side plate 424, and the other is installed on the fourth side plate 427.

[0052] In actual operation, the first side plate 424, the sliding bottom plate 421 and the second side plate 425 together form a sliding accommodating chamber 423, so that the sliding block 42 and the screw rod 32 do not interfere with each other. The second side plate 425, the third side plate 426 and the fourth side plate 427 together form a closed-loop chamber 428 with an opening facing away from the bearing seat 1, so as to further reduce the weight of the sliding block 42 while ensuring the structural stability of the present invention, thereby reducing the manufacturing cost of the present invention. Under the joint action of the above-mentioned sliding accommodating chamber 423 and the closed-loop chamber 428, the present invention has a more compact structure and occupies less space.

[0053] In actual work, Figure 5 As shown, the second side plate 425 is arranged at an angle to further enhance the structural strength of the sliding block 42, and the third side plate 426 is arranged parallel to the bottom of the discharge trough 11, so that the present invention can better install the second sliding limit rod 64 on the sliding block 42. The provision of two first sliding limit rods 62 can further limit the sliding block 42, thereby making the structural stability of the present invention higher.

[0054] Furthermore, the first sliding limit rod 62 and / or the second sliding limit rod 64 may include a transverse sliding rod connected to the sliding block 42 and a sleeve sleeved on the transverse sliding rod. In this way, under the action of the sleeve, the sliding block 42 can not only slide on the bearing seat 1 more conveniently, but also the surface of the sleeve does not need to be smoothed. At this time, the surface accuracy quality requirements of the first sliding limit rod 62 and / or the second sliding limit rod 64 of the present invention are relatively low, and no fine polishing process is required, and the cost is relatively low.

[0055] like Figure 7 As shown, the bracket assembly 5 includes a first bracket 51 connected to the slider assembly 4, a third bracket 53 connected to the central control screen 7, and a second bracket 52 connecting the first bracket 51 and the third bracket 53, the second bracket 52 is arranged obliquely, and the cross-sections of the first bracket 51, the second bracket 52 and the third bracket 53 along the movement direction of the slider assembly 4 are all wavy structures. The second bracket 52 arranged obliquely can reduce the probability of the bracket assembly 5 breaking, thereby improving the structural stability of the present invention, and the bracket assembly 5 with a wavy structure as a whole can further reduce the probability of the bracket assembly 5 breaking, thereby further improving the structural stability of the present invention.

[0056] In actual operation, the working principle of the present invention is as follows: the motor assembly 31 drives the screw rod 32 to rotate through the reducer. The rotation of the screw rod 32 drives the limit block 41 threadedly connected to the screw rod 32 to slide axially along the screw rod 32 during the rotation process. When the limit block 41 slides axially along the screw rod 32, it drives the sliding block 42, the bracket assembly 5 and the central control screen 7 to slide axially along the screw rod 32 in turn. At this time, the position of the central control screen 7 is adjusted.

[0057] Compared with the prior art, the present invention has the following beneficial effects:

[0058] 1. The present invention can realize reliable and stable sliding of the vehicle-mounted central control screen 7, that is, by making full use of the structural dimensions of the box body itself, increasing the span to solve the load-bearing rigidity problem, and directly using the box body coaxial processing to solve the assembly accuracy problem. In addition, the present invention is machined after the box body is die-cast, and its unit cost can be reduced by 30% compared with the conventional multi-guide rod mechanism.

[0059] 2. If Figure 8 As shown, since the central control screen 7 of the present invention is arranged on the bracket assembly 5, the central control screen 7 forms a cantilever structure as a whole, so the two first sliding limit grooves 61 will jointly bear the gravity of the central control screen 7 itself, the moment (torque) generated by the gravity and the dynamic load during vibration, and the second sliding limit groove 63 is mainly used to bear the forward and backward dynamic loads generated by the vehicle during driving (such as when the vehicle accelerates or decelerates). In this way, for the present invention, the screw rod 32 only needs to drive the central control screen 7 to slide through the sliding assembly 4 and the bracket assembly 5 in turn. The screw rod does not need to bear the gravity, gravity moment and dynamic load brought by the mass of the central control screen 7 itself during this process. Therefore, the driving mechanism 3 only provides lateral driving force, and does not bear other additional loads. Therefore, the various structures of the present invention are single-loaded, the overall reliability and durability are greatly improved, and the service life is longer.

[0060] 3. The first sliding limit grooves 61 located on both sides of the bearing seat 1 can be used to limit the sliding block up and down (Z direction), so that the bearing seat 1 can limit the central control screen in the Z direction. The second sliding limit grooves 63 located at the bottom of the discharge trough can be used to limit the sliding block front and back (X direction), so that the bearing seat 1 can limit the central control screen in the X direction, and the bearing seat is in a free movable state in the Y direction, so that the central control screen can slide freely along the Y direction of the discharge trough. In this way, under the joint action of the above three sliding limit grooves, the structural stability of the present invention is higher.

[0061] 4. Since the three sliding limit grooves of the present invention are all arranged on the bearing seat 1, the load (torque) generated by the central control screen in the present invention finally acts on the bearing seat 1 through the above three sliding limit grooves, and the screw rod 32 in the present invention does not need to bear the load generated by the central control screen. In this way, the screw rod 32 is not easy to deform, making it less likely for the present invention to produce a jamming phenomenon. Therefore, the structure of the present invention is more compact, occupies less space, and has higher structural stability.

[0062] 5. In actual work, the three sliding limit grooves on the bearing seat 1 of the present invention can adopt conventional coaxial machining technology to ensure sufficient processing accuracy (the three sliding limit grooves are in a parallel state), and the various components of the present invention can be assembled together without adopting very high assembly accuracy, thereby making the present invention more convenient to use.
