Description

Technical Field

[0001] This utility model relates to the field of automotive steering lock testing technology, specifically an automotive steering lock tongue length testing platform. Background Technology

[0002] As a key component of the vehicle security system, the steering lock plays a crucial role in preventing vehicle theft. Its working principle is not complicated. When the vehicle is turned off, the driver turns the steering wheel, and the internal mechanism of the steering lock automatically locks the steering column, preventing the steering wheel from turning. This simple yet effective design greatly increases the difficulty for car thieves to steal the vehicle. Among the many performance indicators of the steering lock, the bolt length is extremely critical. In order to accurately measure the bolt length of the steering lock and ensure that it meets strict safety standards and design requirements, the steering lock bolt length test bench was developed.

[0003] Existing automotive steering lock bolt length testing methods mostly employ manual testing. The manual operator places the steering lock in the unlocked state, allowing the bolt to extend fully, and then uses tools such as calipers or micrometers to measure from the point where the bolt meets the lock body to the farthest point of the bolt, reading and recording the measurement value. This operation is too cumbersome and the testing process is too long, failing to improve testing efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a test bench for the length of automotive steering lock tongues, in order to solve the problems mentioned in the background.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a test bench for the length of a car steering lock tongue, comprising a test box and a test bench panel. A vertical bracket is detachably mounted on the top of the test bench panel via bolts. An infrared rangefinder is detachably mounted on the front side of the vertical bracket via bolts. A horizontal push assembly is provided on the right side of the top of the test bench panel. A steering lock placement platform is provided between the infrared rangefinder and the horizontal push assembly. Auxiliary connecting assemblies are provided on both sides of the steering lock placement platform at the top of the test bench panel. A steering lock body is placed on the top of the steering lock placement platform. A steering lock placement groove adapted to the steering lock body is opened on the top of the steering lock placement platform.

[0008] Using the above technical solution, during the testing of the automotive steering lock tongue length, the operator places the steering lock body in the steering lock placement slot on the steering lock placement platform. Then, the operator uses the push assembly to push the plug inside the push assembly toward the steering lock body until it passes through the steering lock placement platform and enters the interior of the steering lock body. The test platform is powered through its power interface and connected to a host computer via a LIN bus. The host computer sends locking and unlocking commands to the steering lock body via the LIN bus. The steering lock tongue performs a reciprocating motion of extending and retracting. The extension and retraction lengths of the tongue are calculated using an infrared rangefinder, and the host computer judges the results. When the test is successful, the success indicator light illuminates; when the test fails, the failure indicator light illuminates.

[0009] Preferably, the auxiliary connection assembly includes a connector housing, a groove, a connecting rod, a vertical plate, a hook plate, a spring, and locking bolts. Locking bolts are provided on both sides of the connector housing. A groove is provided inside the connector housing. A connecting rod is provided inside the connector housing.

[0011] With the above technical solution, when testing steering lock bodies of different sizes, the steering lock mounting platform needs to be replaced. During installation, the steering lock mounting platform is placed between the four auxiliary connecting components and pressed down. At this time, the hook plates will be squeezed and move into the interior of the connecting housing. When the hook plates are matched with the reserved slots on the steering lock mounting platform, the spring can push the hook plates to move towards the steering lock mounting platform through the vertical plate. The four hook plates can simultaneously lock the steering lock mounting platform. Conversely, when disassembling, the connecting rod is pulled to separate the hook plates from the reserved slots on the steering lock mounting platform, thus achieving disassembly.

[0030] Specifically, the test chamber 1 has a test platform panel 2 at its top. The sides of the test chamber 1 and the test platform panel 2 are respectively equipped with latches 3 and latch ears 4. From left to right, the top of the test platform panel 2 has a power switch 9, a failure indicator light 8, and a pass indicator light 7. There are four identical sets of latches 3 and latch ears 4, symmetrically distributed about the center line of the test platform panel 2. The advantage of this design is that it facilitates the assembly and disassembly of the test chamber 1 and the test platform panel 2, making it easier to maintain the interior of the test chamber 1. During the use of the automotive steering lock tongue length test bench, the operator places the steering lock body 14 on the steering lock placement platform 10. The steering lock is placed in the slot 13, and then the plug 1205 inside the push assembly 12 is pushed towards the steering lock body 14 by the push assembly 12 until 1205 passes through the steering lock placement platform 10 and enters the interior of the steering lock body 14. The test platform is powered through the power interface of the test platform and connected to the host computer through the LIN bus. The host computer sends the locking and unlocking commands of the steering lock body 14 through the LIN bus. The steering lock tongue makes a reciprocating motion of extending and retracting. The length of the tongue extension and retraction is calculated by the infrared rangefinder 6 and the host computer judges the result. When the test is qualified, the qualified indicator light 7 lights up. When the test is unqualified, the unqualified indicator light 8 lights up.

[0031] Example 2:

[0032] like Figure 1-5 As shown, this is an improvement on the previous embodiment.

[0033] Specifically, the auxiliary connection assembly 11 includes a connector housing 1101, a groove 1102, a connecting rod 1103, a vertical plate 1104, a hook plate 1105, a spring 1106, and locking bolts 1107. Locking bolts 1107 are provided on both sides of the connector housing 1101. A groove 1102 is formed inside the connector housing 1101. A connecting rod 1103 is provided inside the connector housing 1101, and the connecting rod 1103 passes through the connector housing 1101 and extends to... On the outer side of the connector housing 1101, a vertical plate 1104 is fixedly installed at the end of the connecting rod 1103 away from the connector housing 1101. A hook plate 1105 is fixedly installed at the end of the vertical plate 1104 away from the connecting rod 1103. A spring 1106 is sleeved on the outer side of the connecting rod 1103. Four identical auxiliary connecting components 11 are provided, symmetrically distributed in pairs on both sides of the steering lock placement platform 10. The combination of the connecting rod 1103, the vertical plate 1104, and the hook plate 1105 is connected to the connecting rod 1103. The connector housing 1101 is a sliding connection. The two ends of the spring 1106 abut against the connector housing 1101 and the vertical plate 1104, respectively. The hook plate 1105 is snap-fitted to the steering lock mounting platform 10. The advantage is that when testing steering lock bodies 14 of different sizes, the steering lock mounting platform 10 needs to be replaced. During installation, the steering lock mounting platform 10 is snapped between the four auxiliary connecting components 11 and pressed downwards. At this time, the hook plate 1105 will be squeezed towards the connector.

Conversely, during disassembly, the connecting rod 1103 is pulled to separate the hook plate 1105 from the pre-drilled slot on the steering lock placement platform 10, thus enabling disassembly. This method can be used to test steering lock bodies 14 of different sizes.

[0034] Example 3:

[0035] like Figure 1-5 As shown, this is an improvement on the previous embodiment.

[0036] Specifically, the horizontal push assembly 12 includes a horizontal manual push clamp 1201, a first connecting bar 1202, a second connecting bar 1203, a guide rail 1204, and a plug 1205. The horizontal manual push clamp 1201 is fixedly installed on the top of the test bench panel 2. The movable end of the horizontal manual push clamp 1201 is fixedly installed with the first connecting bar 1202 by bolts. The lower part of the first connecting bar 1202 is provided with the guide rail 1204, which is fixedly connected to the test bench panel 2. The second connecting bar 1203 is fixedly installed at the end of the first connecting bar 1202 away from the horizontal manual push clamp 1201, and the end of the second connecting bar 1203 away from the first connecting bar 1202 is fixedly installed with the second connecting bar 1203. A plug 1205 is fixedly installed and connected to an external industrial control computer. The first connecting bar 1202 is slidably connected to the guide rail 1204. The center line of the second connecting bar 1203 and the plug 1205 are on the same horizontal line. The plug 1205 passes through the steering lock placement platform 10 and extends into the interior of the steering lock placement platform 10. The plug 1205 is plugged into the steering lock body 14. The advantage is that during the test, the movable end of the lateral manual push clamp 1201 pushes the hook plate 1105 horizontally towards the steering lock placement platform 10 through the groove 1102 and the connecting rod 1103 until the hook plate 1105 is connected to the steering lock body 14, thus completing the plugging operation.

[0037] Working Principle: When using the automotive steering lock tongue length testing bench, the operator places the steering lock body 14 into the steering lock placement slot 13 of the steering lock placement platform 10. Then, using the movable end of the lateral manual push clamp 1201, the hook plate 1105 is pushed horizontally towards the steering lock placement platform 10 via the groove 1102 and connecting rod 1103 until 1205 passes through the steering lock placement platform 10 and enters the interior of the steering lock body 14. The testing bench is powered through its power interface and connected to a host computer via a LIN bus. The host computer sends locking / unlocking commands to the steering lock body 14 via the LIN bus, causing the steering lock tongue to extend and retract. The infrared rangefinder 6 calculates the extension and retraction lengths of the tongue, and the host computer judges the results. When the test is successful, a pass indicator light illuminates. When test failure occurs, indicator light 7 illuminates. When test failure occurs, indicator light 8 illuminates. When testing steering lock bodies 14 of different sizes, steering lock mounting platform 10 needs to be replaced. During installation, the steering lock mounting platform 10 is inserted between the four auxiliary connecting components 11 and pressed down. At this time, the hook plate 1105 will be squeezed and move into the interior of the connecting housing 1101. When the hook plate 1105 is matched with the reserved slot on the steering lock mounting platform 10, the spring 1106 can push the hook plate 1105 towards the steering lock mounting platform 10 through the vertical plate 1104. The four hook plates 1105 can simultaneously lock the steering lock mounting platform 10. Conversely, when disassembling, pull the connecting rod 1103 to separate the hook plate 1105 from the reserved slot on the steering lock mounting platform 10, and disassembly can be achieved. It can handle the testing of steering lock bodies 14 of different sizes. The design is reasonable and the operation is simple.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
