Description

Technical Field

[0001] This invention relates to the field of testing tooling and fixture technology, specifically a quick-locking fixture for testing instrument panels. Background Technology

[0002] Before leaving the factory, instrument panels require electrical performance testing. This is typically done using testing fixtures to hold the panel in place, with probes inside the fixture contacting the terminal blocks at the rear of the panel to transmit electrical signals to external testing equipment. Existing instrument panel testing fixtures usually employ a push-pull clamp structure. Operators typically need to lock and position both sides of the instrument panel separately during clamping. This step-by-step operation is prone to causing the instrument panel to shift position when force is applied to one side, resulting in uneven clamping force and the risk of deformation or damage to the instrument panel casing. Furthermore, it is difficult to ensure the alignment accuracy between the workpiece and the probes, affecting testing efficiency.

[0003] Furthermore, most existing probe arrays are directly soldered to the bottom adapter PCB board. Because the terminal block positions at the rear of different instrument panel models vary significantly, this fixed-layout fixture is incompatible with multiple instrument panel models, often requiring a complete replacement of the test fixture during model changes. Simultaneously, probes are prone to wear or damage during long-term contact testing. For soldered probe structures, damage to a single probe typically necessitates desoldering and repairing the entire PCB board, resulting in cumbersome maintenance and high replacement costs.

[0004] If the probes are modified to be pluggable in the fixture design, holes need to be reserved on the guide plate of the probe holder for the probes to pass through. These through holes will directly connect the internal PCB board of the fixture to the outside environment. Dust or impurities in the workshop environment can easily fall in through the gaps between the probes and the holes, covering the contacts on the PCB board surface. Over time, dust accumulation will increase the contact impedance between the probes and the PCB board, causing distortion of the detection signal or poor contact, thus affecting the overall electrical testing stability of the equipment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a quick-locking fixture for instrument panel testing, which solves the problems of probe welding and fixing in existing testing fixtures, which makes it difficult to be compatible with multiple instrument panel models and results in high single-point maintenance costs. Additionally, the probe holes are open to the outside, which can easily allow dust to fall into the internal PCB board and affect the stability of electrical signal transmission.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A quick-locking instrument panel testing fixture includes a base plate, a probe holder mounted on the top of the base plate, an adapter mechanism disposed on the outer side of the probe holder, a blocking mechanism disposed on the outer side of the adapter mechanism, a co-positioning fixing mechanism disposed on the top of the base plate, two slide rails fixedly connected to the top of the base plate, a positioning component slidably disposed on the outer side of the two slide rails, and a testing end component placed on the top of the positioning component; The adapter mechanism includes a guide plate, the outer side of which is fixedly connected to the inner wall of the probe holder. A syringe is inserted inside the guide plate, and a contact is slidably connected inside the syringe. Multiple locking holes are provided on the outer side of the syringe.

[0007] Preferably, the detection end component includes an instrument panel, the rear end of which is provided with a terminal block, and the instrument panel is placed on the positioning component.

[0008] Preferably, the adapter mechanism further includes a locking plate, the outer side of which is fixedly connected to the inner wall of the probe holder, and the interior of the locking plate is provided with multiple limiting components.

[0009] Preferably, the limiting component includes a base plate, the outer side of which is fixedly connected to the inside of the locking plate, and a spring is sleeved inside the locking plate.

[0010] Preferably, one end of the spring abuts against the outside of the substrate, and the other end of the spring abuts against a locking head.

[0011] Preferably, the barrier mechanism includes a barrier plate, the outer side of which is fixedly connected to the inner wall of the probe holder, and the barrier plate has multiple positioning holes inside, with rubber pads provided on the inner walls of the multiple positioning holes.

[0012] Preferably, the co-positioning fixing mechanism includes a base, a handle is rotatably connected to the top of the base, one end of the handle away from the grip is rotatably connected to the base, two connecting rods are hinged at the middle bend of the handle, a guide ring is fixedly connected to the top of the base, and a top rod slides through the guide ring.

[0013] Preferably, the co-positioning fixing mechanism further includes a fixing plate, the bottom end of which is slidably connected to the slide rail, and two rod hammers are internally threaded onto the fixing plate, with the outer sides of the two rod hammers contacting the detection end assembly.

[0014] Preferably, the positioning component includes a support base, the bottom end of which is slidably connected to the slide rail, a gear is rotatably connected inside the support base, and multiple slide tracks are provided at the top end of the support base. Connecting blocks are slidably connected to the inner walls of the multiple slide tracks. A limit plate is fixedly connected to the top end of the connecting block, and a rack is fixedly connected to the outer side of the connecting block. The outer side of the rack is meshed with the outer side of the gear.

[0015] Preferably, the end of the connecting rod away from the handle is rotatably connected to the top rod, and the end of the top rod away from the connecting rod is fixedly connected to the fixing plate.

[0016] This invention provides a quick-locking clamp for instrument panel testing. It offers the following advantages: 1. This invention achieves independent positioning and fixing of the probe assembly by using the spring-driven clamp inside the locking plate of the adapter mechanism and the clamping hole on the outside of the syringe. When a single probe is damaged or when it is necessary to test the instrument panel with different terminal arrangements, the operator can directly insert and remove the probes without disassembling the entire fixture or desoldering the bottom PCB board, thus reducing the difficulty of daily maintenance of the equipment and the cost of replacing parts.

[0017] 2. This invention provides dust protection by setting a barrier mechanism on the outside of the adapter mechanism and using a rubber pad installed in the positioning hole of the barrier plate. When the probe is in the pulled-out state, the cut on the rubber pad closes naturally due to the elasticity of the material, blocking the channel to the inside of the probe holder. When the syringe is inserted, the cut is opened and the edge of the rubber pad tightly wraps and adheres to the outer wall of the syringe. While allowing the probe to be disassembled and assembled at any time, it prevents external dust from falling into the surface of the adapter PCB board, ensuring the stability of signal transmission during electrical testing of the instrument panel.

[0018] 3. This invention improves the accuracy and safety of instrument panel clamping through the cooperation of the positioning component and the corresponding fixing mechanism. When placing the instrument panel, the meshing transmission of the gear and rack causes the limiting plates on both sides to move synchronously towards the center, achieving initial center alignment of workpieces of different sizes. Subsequently, rotating the handle drives the hammers on both sides of the fixing plate to synchronously and linearly press the instrument panel through the transmission of the connecting rod and the push rod. This ensures the alignment accuracy of the instrument panel terminal block and probe, and ensures that the force on both sides of the instrument panel is uniform, avoiding structural deformation and damage caused by unilateral pressure.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 -Appendix Figure 3This invention provides a quick-locking clamp for testing instrument panels, including a base plate 1. The base plate 1 provides a stable mounting reference for the entire clamp, ensuring the assembly position of each component and preventing shaking during operation that could affect testing accuracy. A probe holder 2 is mounted on the top of the base plate 1. The probe holder 2 contains signal conversion lines and a PCB board, providing a carrier for electrical signal transmission. An adapter mechanism 4 is provided on the outside of the probe holder 2, used to connect the probe to the terminal block 32 of the instrument panel 31 under test, ensuring stable electrical signal acquisition. A barrier mechanism 5 is provided on the outside of the adapter mechanism 4, used to isolate the probe holder 2 from the external environment, preventing dust intrusion that could affect component operation. A co-positioning fixing mechanism 6 is provided on the top of the base plate 1, used to quickly press and position the instrument panel 31, ensuring that the instrument panel 31 is firmly clamped and subjected to uniform force. Two slide rails are fixedly connected to the top of the base plate 1, providing sliding guidance for the positioning component 7 and the fixing plate 66, ensuring smooth movement. Positioning components 7 are slidably arranged on the outer sides of the two slide rails. The positioning components 7 are used for center alignment and lateral limiting of instrument panels 31 of different specifications, and the top is used to place the instrument panel 31 to be tested.

[0023] Please see the appendix Figure 4 - Appendix Figure 5 The adapter mechanism 4 includes a guide plate 41, the outer side of which is fixedly connected to the inner wall of the probe holder 2. The guide plate 41 is used to orient and guide the syringe 42 to ensure the insertion position of the syringe 42 and avoid misalignment of the contact 43 and the terminal block 32. The syringe 42 is inserted inside the guide plate 41 and is used to support the contact 43, providing installation and extension space for the contact 43 and ensuring stable movement of the contact 43. The contact 43 is slidably connected inside the syringe 42 and is used to fit the contacts of the terminal block 32 of the instrument panel 31 to realize the acquisition and transmission of electrical signals. Multiple locking holes 44 are opened on the outer side of the syringe 42. The locking holes 44 are used to cooperate with the locking head 463 of the limiting component 46 to realize the quick locking and fixing of the syringe 42 and ensure that the probe is installed in place.

[0024] The adapter mechanism 4 also includes a locking plate 45. The outer side of the locking plate 45 is fixedly connected to the inner wall of the probe holder 2. The locking plate 45 is used to install the limiting component 46 and provide stable installation support for the limiting component 46. Multiple limiting components 46 are provided inside the locking plate 45. The limiting components 46 are used to lock and limit the syringe 42 to prevent the syringe 42 from loosening and to ensure stable contact between the probe and the PCB board.

[0025] Please see the appendix Figure 7 - Appendix Figure 8The limiting component 46 includes a base plate 461. The outer side of the base plate 461 is fixedly connected to the inside of the locking plate 45. The base plate 461 is used to provide fixed support for the spring 462, ensuring that the spring 462 is under stable force and avoiding displacement. The spring 462 is sleeved inside the locking plate 45. One end of the spring 462 abuts against the outer side of the base plate 461. The spring 462 is used to provide elastic force to the locking head 463, ensuring that the locking head 463 can be tightly locked into the locking hole 44, realizing the firm locking of the syringe 42. The other end of the spring 462 abuts against the locking head 463. The locking head 463 is used to lock into the locking hole 44 of the syringe 42, realizing the quick locking and positioning of the syringe 42, and facilitating the disassembly and replacement of the probe.

[0026] Please see the appendix Figure 1 - Appendix Figure 2 The detection end component 3 includes an instrument panel 31, which is the core workpiece to be inspected. Its electrical performance is the focus of the inspection operation. A terminal block 32 is provided at the rear end of the instrument panel 31. The terminal block 32 is used to connect with the contact 43 of the adapter mechanism 4 to transmit the electrical signal of the instrument panel 31. The instrument panel 31 is placed on the positioning component 7. The positioning component 7 provides stable support and positioning for the instrument panel 31 to ensure its placement position.

[0027] Please see the appendix Figure 4 and attached Figure 6 The barrier mechanism 5 includes a barrier plate 51. The outer side of the barrier plate 51 is fixedly connected to the inner wall of the probe holder 2. The barrier plate 51 is disposed between the guide plate 41 and the locking plate 45 to separate the space and provide a dustproof base. Multiple positioning holes 52 are provided inside the barrier plate 51. The positioning holes 52 are used for secondary guidance of the syringe 42. The inner walls of the multiple positioning holes 52 are provided with rubber pads 53. The rubber pads 53 have high elasticity and are pre-cut with cross-shaped cuts. When the syringe 42 is not inserted, the cross-shaped cuts are in an elastic closed state to block the hole. When the syringe 42 is inserted, the cross-shaped cuts are pushed open, and the edge of the rubber pad 53 elastically wraps and seals the outer wall of the syringe 42 at the cut, thereby realizing dynamic dust prevention throughout the probe insertion process and preventing dust from entering the PCB board area with the probe.

[0028] Please see the appendix Figure 3 and attached Figure 10 The positioning and fixing mechanism 6 includes a base 61, which is used to fix the positioning and fixing mechanism 6 on the base plate 1, providing a stable installation foundation for the entire mechanism. A handle 62 is rotatably connected to the top of the base 61. The end of the handle 62 away from the grip is rotatably connected to the base 61. The handle 62 serves as an operating component, making it easy for the operator to quickly drive the mechanism to move, thereby enabling the instrument panel 31 to be quickly locked and released. Two connecting rods 63 are hinged at the middle bend of the handle 62. The connecting rods 63 are used to transmit the driving force of the handle 62, driving the top rod 65 to move linearly. A guide ring 64 is fixedly connected to the top of the base 61. The guide ring 64 is used to limit and guide the push rod 65, ensuring that the push rod 65 moves in a straight line and avoiding deviation. The push rod 65 slides through the guide ring 64. The push rod 65 is used to drive the fixed plate 66 to move and transmit the driving force to the clamping component. The same-position fixing mechanism 6 also includes a fixed plate 66. The bottom end of the fixed plate 66 is slidably connected to the slide rail. The fixed plate 66 is used to install the hammer 67 and drive the hammer 67 to move synchronously. Two hammers 67 are connected to the internal threads of the fixed plate 66. 7. The outer sides of the two hammer rods 67 are in contact with the detection end assembly 3. The hammer rods 67 are used to directly press the instrument panel 31 to achieve rapid positioning of the instrument panel 31. At the same time, the length can be adjusted to adapt to different specifications of instrument panels. The end of the connecting rod 63 away from the handle 62 is rotatably connected to the top rod 65 to ensure smooth transmission of the connecting rod 63 and convert the rotational motion of the handle 62 into the linear motion of the top rod 65. The end of the top rod 65 away from the connecting rod 63 is fixedly connected to the fixing plate 66 to ensure that the top rod 65 and the fixing plate 66 move synchronously to achieve displacement of the hammer rods 67.

[0029] Please see the appendix Figure 3 and attached Figure 9 The positioning component 7 includes a support base 71, the bottom end of which is slidably connected to a slide rail. The support base 71 supports the instrument panel 31, providing a stable placement platform for the instrument panel 31. A gear 72 is rotatably connected inside the support base 71, which is used to realize the synchronous reverse movement of the racks 73 on both sides, ensuring that the limiting plate 75 is synchronously aligned and adjusted. Multiple slide tracks are provided at the top of the support base 71, and connecting blocks 74 are slidably connected to the inner walls of the multiple slide tracks. The slide tracks provide sliding guidance for the connecting blocks 74, ensuring that the connecting blocks 74 move smoothly. The connecting block 74 is used to connect the rack 73 and the limiting plate 75 to transmit displacement. The top of the connecting block 74 is fixedly connected to the limiting plate 75, which is used to laterally limit the instrument panel 31 to prevent the instrument panel 31 from shifting. The rack 73 is fixedly connected to the outside of the connecting block 74. The rack 73 is used to mesh with the gear 72 to transmit motion power. The outside of the rack 73 and the outside of the gear 72 are meshed. The meshing transmission can realize that the racks 73 on both sides move synchronously in opposite directions, driving the limiting plate 75 to be aligned synchronously, improving positioning efficiency and accuracy.

[0030] Working principle: The instrument panel testing fixture uses the base plate 1 as the overall installation reference. All mechanical components are assembled on the base plate 1. After the instrument panel 31 is placed on the support seat 71 of the fixture, the terminal block 32 at the rear end of the instrument panel 31 is aligned with the adapter mechanism 4. The guide plate 41, the syringe 42 and the contact 43 cooperate with each other so that the contact 43 fits against the corresponding contact position of the terminal block 32. The probe seat 2 is equipped with signal conversion circuits and PCB board to transmit the electrical signals of the instrument panel 31 collected by the terminal block 32 to the external testing equipment, thereby completing the electrical performance testing of the instrument panel 31.

[0031] After the instrument panel 31 is placed on the bearing seat 71 of the fixture, the positioning fixing mechanism 6 is fixedly installed on the base plate 1 through the base 61. The operator turns the handle 62, and the end of the handle 62 away from the grip rotates on the base 61. At this time, the handle 62 drives the connecting rod 63 on the outside of the middle bend to transmit power. Through the connecting rod 63 and under the limiting and guiding action of the guide ring 64, the push rod 65 is driven to make linear reciprocating motion. The push rod 65 is connected to the fixing plate 66. At this time, the two ends of the fixing plate 66 are driven forward, causing the hammer 67 to move synchronously. The hammer 67 quickly presses and positions the instrument panel 31 in place, while ensuring that the clamping force of the instrument panel 31 is uniform, avoiding deformation and structural damage of the instrument panel 31 caused by unilateral compression. The tail end of the hammer 67 has a threaded end, and the length can be adjusted by rotating the hammer 67 in conjunction with the fixing plate 66 as needed.

[0032] As a pre-positioning process, the positioning component 7 supports the instrument panel 31 workpiece through the bearing seat 71. The gear 72 and rack 73 mesh with each other to form a synchronous transmission structure. The connecting block 74 moves synchronously with the rack 73, driving the limit plate 75 to move. After the instrument panel 31 is placed, one of the limit plates 75 is pushed, and the rack 73 on one side moves through the connecting block 74. At this time, the gear 72 and rack 73 drive the limit plate 75 on the other side to move towards the center position, thereby realizing the synchronous centering adjustment of the positioning components on both sides. It can perform center alignment and lateral limiting for instrument panels 31 of different specifications and sizes, ensuring that the instrument panel 31 is placed in a uniform position, preventing the terminal block 32 and contact 43 from being misaligned due to placement offset, and improving the detection alignment accuracy and equipment universality and adaptability.

[0033] After the instrument panel 31 is positioned, the positioning and fixing mechanism 6 pushes the instrument panel 31 to the 2nd side, so that the contact 43 fits against the corresponding contact position of the terminal block 32. The probe in the adapter mechanism 4 is guided by the guide plate 41, passes through the blocking mechanism 5, and is limited and fixed by the locking plate 45. Finally, the tail end contacts the contact point of the PCB board inside the probe holder 2 to achieve electrical connection. The probe has a syringe 42 as the main body, and has a telescopic contact 43 inside. The outside of the syringe 42 has a card hole 44 that matches the limiting component 46. After the probe is inserted, it will contact the limiting component 46 inside the locking plate 45 when it passes through the locking plate 45. At this time, as it is continuously pushed forward... The outer wall of the syringe 42 contacts the clamp 463, and the clamp 463 will eventually snap into the clamp hole 44. The spring 462 provides elastic extension allowance for the contact 43. The other end is based on the base plate 461. When two clicks are heard or two locking sensations are felt after pushing in, it indicates that the probe has been fixed in place. Finally, the modular disassembly and positioning of the probe is realized. According to the different terminal block 32 layouts of different models of instrument panel 31, a single probe can be adjusted or replaced individually without disassembling and replacing the entire fixture body. It is suitable for the detection conditions of multiple types of instrument panel 31. Moreover, the contact 43 of a single probe can be replaced independently when damaged, reducing equipment maintenance and parts replacement costs.

[0034] When the probe is inserted, the isolation mechanism 5 ensures that the inside of the probe holder 2 is isolated from the external environment. The isolation mechanism 5 consists of an isolation plate 51, a positioning hole 52, and a rubber pad 53. The rubber pad 53 is made of high-resilience silicone and serves as an elastic dustproof isolation layer. It is placed in the positioning hole 52 of the isolation plate 51. The rubber pad 53 has a cross-shaped cut beforehand to achieve dynamic dustproofing without maintenance during insertion and removal. When the syringe 42 is not inserted, the cross-shaped cut is in a naturally closed state due to the elasticity of the rubber pad 53, which can seal the channel leading downward to the adapter PCB board and prevent dust from falling into the adapter P. When the syringe 42 is inserted into the CB board, the lower half of the syringe 42 passes through the positioning hole 52 of the barrier plate 51 and pushes down to open the cross-shaped cut on the rubber pad 53. At this time, the elastic edge formed by the cross-shaped cut tightly wraps around the outer wall of the syringe 42, forming a tight seal to prevent dust from falling onto the adapter PCB board through the gap between the syringe 42 and the positioning hole 52. After the syringe 42 is pulled out, the elastic petals of the rubber pad 53 instantly rebound, and the cross-shaped cut returns to the closed state, restoring the dustproof effect and preventing dust from affecting the stability of the detection signal transmission and the service life of the components.
