Description

Technical Field

[0001] This invention belongs to the field of automotive assembly technology, specifically relating to a mounting bracket and installation method for precise assembly of automotive dashboards. Background Technology

[0002] The automotive dashboard, also known as the center console or instrument panel assembly, is a core module in the vehicle's cockpit that integrates functionality, safety, and interior aesthetics. It not only forms the overall visual interface in front of the driver and passengers but is also a highly integrated and complex system platform. It mainly consists of the air conditioning assembly, dashboard frame, wiring harness, computer board, network pipes, fuse box, controller, steering column, instruments, and coverings. During automotive assembly, the dashboard is typically hoisted into position using lifting fixtures and then assembled manually after alignment.

[0003] Chinese patent application number CN202520021369.4 discloses a car dashboard mounting assist arm, including a boom, a vertical rotating arm, and a horizontal tilting arm. The boom is arranged horizontally, the vertical rotating arm is arranged vertically, and the upper end of the vertical rotating arm is rotatably connected to one end of the boom. The horizontal tilting arm is arranged horizontally, and one end of the horizontal tilting arm is rotatably connected to the lower end of the vertical rotating arm. The other end of the horizontal tilting arm is connected to a balance arm. A first clamping arm is fixedly mounted on one end of the balance arm, and a second clamping arm is slidably mounted on the other end of the balance arm. Positioning pins are provided on the opposite surfaces of the first and second clamping arms. A side pressure block is also provided on the balance arm, and the side pressure block is driven by a guide rod cylinder. The beneficial effects of this utility model include: simple structure and convenient operation, realizing labor-saving assembly of car dashboards, improving assembly efficiency, and reducing the labor intensity of workers.

[0004] In the current automotive dashboard assembly process, workers first pre-assemble the heaviest and largest components, the air conditioning assembly and the dashboard frame, to form the main structure of the dashboard. After the dashboard is pre-assembled, relatively independent or lighter components such as the steering column, instrument cluster, central control screen, and trim panels are installed relatively easily. However, during the main assembly, the air conditioning assembly and dashboard frame are manually lifted and placed onto the lifting equipment. The large weight and volume of these components make the pre-assembly process very laborious. Manual installation also makes it difficult to accurately align the corresponding mounting holes on the air conditioning assembly and dashboard frame. Furthermore, the irregular outer contour of the air conditioning assembly during pre-assembly makes it easy for it to collide with the dashboard frame. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a mounting bracket for the precise assembly of automotive dashboards. Through the coordinated operation of a first bracket assembly, a first lifting tool, a second bracket assembly, and a second lifting tool, this invention enables workers to pre-assemble the bulky and heavy air conditioning assemblies and dashboard frames without manual handling, thus saving time and effort and achieving high-efficiency manufacturing. Simultaneously, it increases the precision of pre-assembly of the air conditioning assemblies and dashboard frames, achieving high-quality manufacturing. Furthermore, it avoids collisions between the irregularly shaped air conditioning assemblies and dashboard frames during pre-assembly, improving product quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mounting bracket for precise assembly of an automotive dashboard includes a first bracket assembly. The first bracket assembly includes two first supports, with a first turntable and a first chuck fixedly connected to each first support. The first chuck can lock the rotation of the first turntable. A first hanger is positioned between the two first supports, with its two ends fixedly connected to the centers of the two first turntables. A sliding mounting seat and a sliding caliper are slidably connected to the first hanger. The dashboard frame is detachably mounted on the sliding mounting seat and the sliding caliper. A second bracket assembly is fixedly connected to the rear of the first bracket assembly. The second bracket assembly includes two second supports, with a second turntable and a second chuck fixedly connected to each second support. The second chuck can lock the rotation of the second turntable. A second hanger is positioned between the two second supports, with its two ends fixedly connected to the centers of the two second turntables. An air conditioning assembly is detachably mounted on the second hanger. The first hanger is configured such that when the first hanger rotates towards the second bracket assembly and is above the second hanger, the projections of the first and second hangers in the horizontal plane coincide.

[0008] Furthermore, the first lifting device includes a first crossbeam and a first C-beam. The two ends of the first crossbeam are fixedly connected to the two ends of the first C-beam, and a middle beam is fixedly connected to the inner side of the first C-beam. The length direction of the middle beam is consistent with the length direction of the side of the first C-beam away from the first crossbeam. The sliding fixing seat and the sliding clamp are both slidably connected to the middle beam and the side of the first C-beam away from the first crossbeam.

[0009] Furthermore, the sliding caliper includes a caliper base, a fixed clamp fixedly connected to the top of the caliper base, and a fixed plate fixedly connected to the bottom of the caliper base. The sliding clamp passes through the top and bottom of the caliper base and is slidably connected to a groove in the caliper base. The sliding caliper includes a lead screw, one end of which is rotatably connected to the fixed plate, and the other end is drively connected to the upper part of the sliding clamp. The length direction of the lead screw is consistent with the length direction of the groove.

[0010] Furthermore, the sliding caliper includes a limiting plate, one end of which is fixedly connected to the fixing plate, and the other end is slidably connected to the upper part of the sliding clamp. The caliper base, the fixing plate, the limiting plate, and the upper part of the sliding clamp together surround and contact the first C-beam and the middle beam.

[0011] Furthermore, racks are provided on both opposite sides of the first C-beam and the middle beam near the sliding caliper. The gear located between the caliper seat and the limiting plate meshes with the two racks. The center of the gear is fixedly connected to one end of the rotating rod, and the other end of the rotating rod passes through the limiting plate. The rotating rod is rotatably connected to the limiting plate.

[0012] Furthermore, the instrument panel frame includes a first horizontal frame, which is fixedly connected to one end of two vertical frames, and the other ends of the two vertical frames are respectively fixedly connected to both ends of a third horizontal frame. One of the vertical frames is fixedly connected to one end face of the first horizontal frame, and the side of the vertical frame facing away from the first horizontal frame is fixedly connected to one end face of a second horizontal frame. The sliding fixing seat detachably clamps the first horizontal frame, and the sliding caliper detachably clamps the second horizontal frame.

[0013] Furthermore, the first support assembly includes a first base plate, on which two slide rails are fixedly connected. Two first supports are slidably connected to the corresponding slide rails, the length direction of which is perpendicular to the length direction of the first lifting device. The two first supports are fixedly connected to both ends of the connecting column. The second support assembly includes a second base plate, on which two second supports are fixedly connected.

[0014] Furthermore, the second lifting device includes a second crossbeam and a second C-beam, with the two ends of the second crossbeam fixedly connected to the two ends of the second C-beam.

[0015] Furthermore, the second lifting device includes two first fixed seats, which are fixedly connected to the second crossbeam. Two second fixed seats and one third fixed seat are fixedly connected to the second C-beam, and the third fixed seat is located between the two second fixed seats.

[0016] This invention also claims a method for mounting using the above-described mounting bracket for precise assembly of automotive dashboards, comprising the following steps:

[0017] S101: Rotate the second turntable until the second lifting device is in a horizontal state, and use the second chuck to lock the rotation of the second turntable so that the second lifting device remains horizontal;

[0018] S102: The air conditioning assembly is clamped and installed on the second hanger, with the back of the air conditioning assembly facing the first hanger and the front of the air conditioning assembly clamped on the second hanger facing upward;

[0019] S103: The instrument panel frame is clamped and installed on the sliding fixed seat and sliding caliper of the first lifting device, with the front of the instrument panel frame facing the first lifting device;

[0020] S104: Rotate the first turntable so that the first hanger rotates toward the direction above the second hanger, so that the back of the dashboard frame clamped on the first hanger is close to the front of the air conditioning assembly;

[0021] S105: Use the first chuck to hold the rotation of the first turntable, and then adjust the relative position of the dashboard frame and the air conditioning assembly by moving the sliding caliper and the first support on the slide rail.

[0022] S106: After aligning the instrument panel frame with the assembly holes of the air conditioning assembly and fixing them in place, release the first chuck and rotate the first turntable until the first hanger returns to its original position to complete the pre-assembly of the instrument panel body.

[0023] S107: Assembly of smaller and lighter components such as wiring harnesses, computer boards, network pipes, fuse boxes, controllers, steering columns, instruments, and skins on the main body of the instrument panel, which consists of the instrument panel frame and the air conditioning assembly.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) In this invention, workers can complete the pre-assembly of the air conditioning assembly and instrument panel frame, which are large in size and weight, without having to move them manually. After the air conditioning assembly is fixedly installed on the second hanger, the second turntable is rotated so that the front of the air conditioning assembly is facing up. The second chuck is used to hold the rotation of the second turntable. Then, the instrument panel frame is clamped and installed on the sliding fixed seat and sliding clamp of the first hanger. The first turntable is rotated so that the first hanger rotates towards the direction above the second hanger, so that the back of the instrument panel frame clamped on the first hanger is close to the front of the air conditioning assembly. The first chuck is used to hold the rotation of the first turntable. Then, the relative position of the instrument panel frame and the air conditioning assembly is adjusted by moving the sliding clamp and the first support on the slide rail. After fine-tuning and aligning the corresponding assembly holes on the instrument panel frame and the air conditioning assembly, the fixed assembly is performed. This saves time and effort to complete the pre-assembly of the instrument panel body. The core components with large size and heavy weight are pre-assembled into the instrument panel body. This design avoids the overall weight being too heavy and allows for individual adjustments, thereby greatly improving the assembly efficiency and achieving high-efficiency manufacturing.

[0026] (2) This invention also increases the accuracy of pre-assembly of the air conditioning assembly and the instrument panel frame. During the pre-assembly process, after the back of the instrument panel frame clamped on the first hanger is close to the front of the air conditioning assembly, rotating the rotating rod fixedly connected to the center of the gear can drive the entire sliding caliper to move along the length of the middle beam. Moreover, the sliding of the sliding caliper can drive the movement of the instrument panel frame. Thus, the instrument panel frame can be moved and adjusted along the length of the first hanger by the sliding caliper installed on the first C-beam and the middle beam. Because the first support is slidably connected to the slide rail and the sliding direction is perpendicular to the length of the first hanger, the instrument panel frame can be moved and adjusted along the direction perpendicular to the length of the first hanger by sliding the first support. This allows workers to easily and accurately perform three-dimensional fine-tuning of the assembly holes on the instrument panel frame and the air conditioning assembly, achieve millimeter-level alignment, improve assembly accuracy and quality, ensure the consistency of assembly and installation, reduce stress, abnormal noise and uneven gaps caused by misalignment, and achieve high-quality manufacturing.

[0027] (3) This invention can also avoid collision damage between the irregularly shaped air conditioning assembly and the dashboard frame during pre-installation. When the first turntable rotates and the first hanger holding the dashboard frame rotates towards the second hanger holding the air conditioning assembly, the vertical frame of the dashboard frame has a certain curvature. The third horizontal frame, fixedly connected to the vertical frame, needs to bypass the irregular contours of the front and bottom surfaces of the air conditioning assembly to reach the predetermined position. Directly lowering the dashboard frame from the front of the air conditioning assembly can easily cause the third horizontal frame to collide with and damage the irregular contours of the front and bottom surfaces of the air conditioning assembly. Figure 9 As shown in the figure, the black arrow indicates the movement trajectory of the third crossbeam. When using the installation method of the present invention, the third crossbeam rotates together with the first hanger. The third crossbeam moves in an arc and approaches the bottom surface of the air conditioning assembly at a certain angle, thereby avoiding collision damage between the irregularly shaped air conditioning assembly and the dashboard frame during the pre-installation process.

[0047] Example

[0048] like Figures 1-10 As shown, a mounting bracket for precise assembly of an automotive dashboard includes a first bracket assembly 100. The first bracket assembly 100 includes two first supports 101. A first turntable 102 and a first chuck 103 are fixedly connected to the first supports 101. The first chuck 103 can lock the rotation of the first turntable 102. A first hanger 200 is placed between the two first supports 101. The two ends of the first hanger 200 are respectively fixedly connected to the centers of the two first turntables 102. A sliding fixing seat 205 and a sliding clamp 206 are slidably connected to the first hanger 200. The dashboard frame 600 is detachably mounted on the sliding fixing seat 205 and the sliding clamp 206. A second bracket assembly 300 is fixedly connected to the rear side of the first bracket assembly 100. The second bracket assembly 300 includes two second supports 301. A second turntable 302 and a second chuck 303 are fixedly connected to the second supports 301. The second chuck 303 can lock the rotation of the second turntable 302. A second hanger 400 is placed between the two second supports 301. The two ends of the second hanger 400 are respectively fixedly connected to the centers of the two second turntables 302. An air conditioning assembly 500 is detachably mounted on the second hanger 400. The first hanger 200 is configured such that when the first hanger 200 rotates towards the second bracket assembly 300 and above the second hanger 400, the projection portions of the first hanger 200 and the second hanger 400 on the horizontal plane coincide.

[0049] Furthermore, the second lifting device 400 includes a second crossbeam 401 and a second C-beam 402, with both ends of the second crossbeam 401 fixedly connected to both ends of the second C-beam 402. The second lifting device 400 includes two first fixed seats 403, which are fixedly connected to the second crossbeam 401. Two second fixed seats 404 and one third fixed seat 405 are fixedly connected to the second C-beam 402, with the third fixed seat 405 located between the two second fixed seats 404.

[0050] In this invention, workers can pre-assemble the large-volume and heavy air conditioning assembly and dashboard frame without manual handling. The first fixing seat 403, the second fixing seat 404, and the third fixing seat 405, which are fixedly connected to the second lifting device 400, can tightly fit the outer contour of the bottom and back of the air conditioning assembly 500 and achieve a clamping effect. After the air conditioning assembly 500 is fixedly installed on the second lifting device 400, the second turntable 302 is rotated so that the front of the air conditioning assembly 500 faces upward. The second chuck 303 clamps the rotation of the second turntable 302, keeping the second lifting device 400 horizontal. Then, the dashboard frame 600 is clamped and installed on the sliding fixing seat 205 and the sliding clamp 206 of the first lifting device 200. The first turntable 102 is rotated so that the first lifting device 200 is rotated in the direction above the second lifting device 400. The movement brings the back of the instrument panel frame 600, clamped on the first lifting device 200, close to the front of the air conditioning assembly 500. The first chuck 103 holds the rotation of the first turntable 102. The relative positions of the instrument panel frame 600 and the air conditioning assembly 500 are adjusted by moving the sliding caliper 206 and the first support 101 on the slide rail 105. After fine-tuning and aligning the corresponding assembly holes on the instrument panel frame 600 and the air conditioning assembly 500, they are fixedly assembled. The first chuck 103 is released, and the first turntable 102 is rotated until the first lifting device 200 returns to its original position. This saves time and effort to complete the pre-assembly of the instrument panel body. The core components, which are larger and heavier, are pre-assembled into the instrument panel body. This design avoids excessive overall weight and allows for individual adjustments, thereby greatly improving assembly efficiency and achieving high-efficiency manufacturing.

[0051] It is worth noting that both the first turntable 102 and the second turntable 302 have a steering wheel structure that facilitates rotation, making it convenient for workers to rotate and adjust the first lifting device 200 and the second lifting device 400. Moreover, both the first chuck 103 and the second chuck 303 can firmly clamp the rotation of the lifting device. All of the above components are existing technologies and will not be described in detail here.

[0052] Furthermore, the first lifting device 200 includes a first crossbeam 201 and a first C-beam 202. The two ends of the first crossbeam 201 are fixedly connected to the two ends of the first C-beam 202. A middle beam 203 is fixedly connected to the inner side of the first C-beam 202, and the length direction of the middle beam 203 is consistent with the length direction of the side of the first C-beam 202 away from the first crossbeam 201. The sliding fixing seat 205 and the sliding clamp 206 are both slidably connected to the middle beam 203 and the side of the first C-beam 202 away from the first crossbeam 201.

[0053] Furthermore, the sliding caliper 206 includes a caliper base 2061, a fixing clamp 2062 fixedly connected to the top of the caliper base 2061, and a fixing plate 2066 fixedly connected to the bottom of the caliper base 2061. The sliding clamp 2063 passes through the top and bottom surfaces of the caliper base 2061 and is slidably connected to the sliding groove 2064 of the caliper base 2061. The sliding caliper 206 includes a lead screw 2065, one end of which is rotatably connected to the fixing plate, and the other end is drively connected to the upper part of the sliding clamp 2063. The length direction of the lead screw 2065 is consistent with the length direction of the sliding groove 2064.

[0054] Furthermore, the sliding caliper 206 includes a limiting plate 2068, one end of which is fixedly connected to the fixing plate 2066, and the other end is slidably connected to the upper part of the sliding clamp 2063. The caliper base 2061, the fixing plate 2066, the limiting plate 2068, and the upper part of the sliding clamp 2063 together surround and contact the first C-beam 202 and the intermediate beam 203.

[0055] Furthermore, racks 204 are provided on both opposite sides of the first C-beam 202 and the middle beam 203 near the sliding caliper 206. A gear 2067 located between the caliper seat 2061 and the limiting plate 2068 meshes with the two racks 204. The center of the gear 2067 is fixedly connected to one end of the rotating rod 2069. The other end of the rotating rod 2069 passes through the limiting plate 2068, and the rotating rod 2069 is rotatably connected to the limiting plate 2068.

[0056] Furthermore, the first support assembly 100 includes a first base plate 106, on which two slide rails 105 are fixedly connected. Two first supports 101 are slidably connected to their respective slide rails 105. The length direction of the slide rails 105 is perpendicular to the length direction of the first lifting device 200. The two first supports 101 are fixedly connected to both ends of the connecting column 104. The second support assembly 300 includes a second base plate 304, on which two second supports 301 are fixedly connected.

[0057] In this invention, the accuracy of pre-assembly of the air conditioning assembly 500 and the dashboard frame 600 is increased. During the pre-assembly process, after the back of the dashboard frame 600, clamped on the first hanger 200, comes into close contact with the front of the air conditioning assembly 500, the gear 2067 on the sliding caliper 206 meshes with the rack 204 on the first C-beam 202 and the intermediate beam 203. Rotating the rotating rod 2069, which is fixedly connected to the center of the gear 2067, can drive the entire sliding caliper 206 to move along the length of the intermediate beam 203. Moreover, by rotating the lead screw 2066 on the sliding caliper 206, the sliding clamp 2063 can slide in the slide groove 2064 and clamp the first crossbeam 601 of the dashboard frame 600. Therefore, the sliding of the sliding caliper 206 can drive the movement of the dashboard frame 600, thereby moving it through the first C-beam 202 and the intermediate beam 203. The sliding caliper 206 enables the instrument panel frame 600 to move and adjust along the length of the first hanger 200. Because a slide rail 105 is fixedly connected to the first base plate 106, and the first support 101 is slidably connected to the slide rail with the sliding direction perpendicular to the length of the first hanger 200, the instrument panel frame 600 can be moved and adjusted in a direction perpendicular to the length of the first hanger 200 by sliding the first support 101. Moreover, the two first supports 101 are fixedly connected by the connecting column 104 to ensure the consistency of movement of the two first supports 101. This allows workers to easily and accurately perform three-dimensional fine-tuning of the assembly holes on the instrument panel frame 600 and the air conditioning assembly 500, achieving millimeter-level alignment, improving assembly accuracy and quality, ensuring the consistency of assembly and installation, reducing stress, abnormal noise and uneven gaps caused by misalignment, and achieving high-quality manufacturing.

[0058] Furthermore, the instrument panel frame 600 includes a first horizontal frame 601, which is fixedly connected to one end of two vertical frames 603, and the other ends of the two vertical frames 603 are respectively fixedly connected to both ends of a third horizontal frame 604. One side of the vertical frame 603 is fixedly connected to one end face of the first horizontal frame 601, and the side of the vertical frame 603 facing away from the first horizontal frame 601 is fixedly connected to one end face of a second horizontal frame 602. The sliding fixing seat 205 detachably clamps the first horizontal frame 601, and the sliding caliper 206 detachably clamps the second horizontal frame 602.

[0059] In this invention, it is possible to avoid collision damage between the irregularly shaped air conditioning assembly 500 and the dashboard frame 600 during pre-installation. When rotating the first turntable 102, the first lifting device 200 holding the dashboard frame 600 rotates towards the second lifting device 400 holding the air conditioning assembly 500. Because the vertical frame 603 of the dashboard frame 600 has a certain curvature, the third horizontal frame 604, fixedly connected to the vertical frame 603, needs to bypass the irregular contours of the front and bottom surfaces of the air conditioning assembly 500 to reach the predetermined position. Directly lowering the dashboard frame 600 from directly in front of the air conditioning assembly 500 can easily cause the third horizontal frame 604 to collide with the irregular contours of the front and bottom surfaces of the air conditioning assembly 500. Figure 9 As shown in the figure, the black arrow indicates the movement trajectory of the third crossbeam 604. When using the installation method of the present invention, the third crossbeam 604 rotates together with the first hanger 200. The third crossbeam 604 moves in an arc and approaches the bottom surface of the air conditioning assembly 500 at a certain angle, thereby avoiding collision damage between the irregularly contoured air conditioning assembly 500 and the dashboard frame 600 during the pre-installation process.

[0060] An installation method using the aforementioned mounting bracket for precise assembly of automotive dashboards includes the following steps:

[0061] S101: Rotate the second turntable 302 until the second lifting device 400 is in a horizontal state, and use the second chuck 303 to hold the rotation of the second turntable 302 so that the second lifting device 400 remains horizontal;

[0062] S103: The air conditioning assembly 500 is clamped and installed on the second hanger 400, with the back of the air conditioning assembly 500 facing the first hanger 200 and the front of the air conditioning assembly 500 clamped on the second hanger 400 facing upwards.

[0063] S102: The instrument panel frame 600 is clamped and installed on the sliding fixing seat 205 and sliding clamp 206 of the first lifting device 200, with the front of the instrument panel frame 600 facing the first lifting device 200.

[0064] S104: Rotate the first turntable 102 so that the first hanger 200 rotates toward the direction above the second hanger 400, so that the back of the dashboard frame 600 clamped on the first hanger 200 is close to the front of the air conditioning assembly 500;

[0065] S105: Use the first chuck 103 to hold the rotation of the first turntable 102, and then adjust the relative position of the dashboard frame 600 and the air conditioning assembly 500 by moving the sliding caliper 206 and the first support 101 on the slide rail 105.

[0066] S106: After aligning the assembly holes of the instrument panel frame 600 with the air conditioning assembly 500 and fixing them in place, release the first chuck 103, rotate the first turntable 102 until the first hanger 200 returns to its original position, and complete the pre-assembly of the instrument panel body.

[0067] S107: Assembly of smaller and lighter components such as wiring harnesses, computer boards, network pipes, fuse boxes, controllers, steering columns, instruments and skins on the instrument panel body, which consists of the instrument panel frame 600 and the air conditioning assembly 500.

[0068] It is worth noting that after the instrument panel body, consisting of the instrument panel frame 600 and the air conditioning assembly 500, is pre-assembled, the first turntable 102 is rotated until the first lifting device 200 returns to its original position. Then, the second turntable 302 is rotated, which allows the instrument panel body to tilt upward at a certain angle. The first chuck 103 then holds the rotation of the first turntable 102, allowing the worker to adjust the instrument panel body to the most convenient tilt angle for assembly while standing on the side closest to the first support assembly 100. This facilitates the subsequent assembly of smaller and lighter components such as wiring harnesses, computer boards, network tubes, fuse boxes, controllers, steering columns, instruments, and skins, thus improving assembly efficiency.

[0069] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
