In this process, each time the 8-shaped groove and the sliding block involved in gas storage move with the air pushing plate with the connecting rod, the reaction force on the groove wall of the 8-shaped groove will gradually increase, but due to its arc-shaped design, the force can be effectively dispersed, and the point of action of the force can be adjusted in real time at different positions of the groove wall of the 8-shaped groove during the rotation of the rotating disk. The above design can maintain a good performance state during long-term operation.

Description

Technical Field

[0001] The invention relates to the technical field of electronic parking device detection, in particular to an electronic parking device comprehensive detection platform. Background Art

[0002] In the field of modern automobile manufacturing and related parts testing, the performance test of the electronic parking device is a key link to ensure the safety of vehicle parking. At present, when testing the electronic parking device, the common practice is to place the electronic parking device on the test bench, then fix it with a clamp, and then plug in the test circuit to carry out the corresponding test work.

[0003] However, this traditional detection and fixing method has many problems. During the manual installation and tightening process, it is inevitable that the installation position deviates from the detection deviation. There is usually a position sensor inside the electronic parking device to monitor the position of the brake component; when the position fixation deviates, the position information sensed by the position sensor will be wrong; for example, the sensor will misjudge the distance between the brake pad and the brake disc, and judge it as incomplete braking or over-braking; this erroneous signal feedback will affect the control unit of the electronic parking device, making it unable to accurately adjust the braking force according to the actual situation, and when detecting the accuracy and reliability of the position sensor, the detection results obtained are also inaccurate.

[0004] At the same time, in terms of electrical connection stability detection, position deviation will affect the electrical connection of the electronic parking device; if the position of the electronic parking device in the fixture is offset, the detection cable connected to its interface will be pulled or bent; when detecting the stability of the electrical connection, this abnormal cable state will lead to poor contact, causing the detected electrical parameters such as current and voltage to jump or interrupt instantly, and, if it is in this position deviation state for a long time, it will damage the electrical interface, affecting the normal electrical function of the electronic parking device, and providing erroneous judgment basis for the detection work.

[0005] In addition, when there are dust and other particles on the fixture, these particles will be between the contact surface of the fixture and the electronic parking device when the electronic parking device is fixed. This will first cause the clamping force of the fixture on the electronic parking device to be unevenly distributed; for example, when testing key mechanical performance indicators such as braking torque, due to the uneven clamping force caused by dust particles, the electronic parking device is very likely to have a slight displacement during the testing process, making it impossible to maintain an ideal fit and pressure distribution between the braking components (such as the brake disc and the brake pad), which in turn causes a large deviation between the measured braking torque value and the actual accurate value, seriously interfering with the accurate judgment of the real braking ability of the electronic parking device; secondly, the presence of dust and other particles will also change the friction characteristics between the fixture and the electronic parking device. When testing parameters that require high-precision positioning, such as the calibration test of the internal position sensor of the electronic parking brake, the friction force is affected by these impurities and abnormalities occur. The electronic parking brake will slip in the fixture, causing the position that should have been accurately tested to change. In this case, the signal fed back by the position sensor loses its due accuracy, and the test data cannot truly reflect the actual working status of this part of the electronic parking brake, resulting in the technicians being unable to reliably determine whether the position sensor is working properly, affecting the accurate control of the performance of the electronic parking brake throughout the entire testing process.

[0006] Therefore, the present invention proposes an electronic parking device comprehensive testing platform to solve the above problems. Summary of the invention

[0007] In view of this, the technical problem to be solved by the present invention is to propose an electronic parking device comprehensive testing platform to solve the problems existing in the prior art.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electronic parking device comprehensive testing platform, comprising: a testing platform, a fixture group, and also comprising: a position deviation judgment component and a detection accuracy maintenance component, wherein the position deviation judgment component is located above the detection accuracy maintenance component; the position deviation judgment component is used to judge the detection position of the fixed electronic parking device; the detection accuracy maintenance component is used to eliminate interference factors on the surface of the fixture group to ensure the fastening ability of the fixture group.

[0009] As an improvement, the position deviation judgment component includes a rotating disk rotatably connected to the clamp group, a detection strip A is fixedly connected to the rotating disk, and a bayonet is provided on the detection strip A.

[0010] As an improvement, the front end of the detection strip A is fixedly connected to a fixed column, a friction plate is fixedly sleeved on the fixed column, the detection strip B is rotatably connected to the outer ring surface of the friction plate on the fixed column, and a position determination column is fixedly connected to the clamp group.

[0011] As an improvement, the inner surface of the detection strip A is fixedly connected with an electric contact strip A, and the bottom surface of the detection strip B is fixedly connected with an electric contact strip B.

[0012] As an improvement, the detection strip A is fixedly connected with an alignment mark A, the detection strip B is fixedly connected with an alignment mark B, a Hall switch card is arranged below the detection strip A, and an indicator light is fixedly connected to the Hall switch card.

[0013] As an improvement, the detection accuracy maintenance component includes an 8-shaped groove opened on the rotating disk, a sliding block is slidably connected in the 8-shaped groove, a connecting rod is fixedly connected to the sliding block, and an air pusher is fixedly connected to the end of the connecting rod away from the sliding block.

[0014] As an improvement, an auxiliary cavity part is fixedly connected to the clamp group, the Hall switch card is clamped on the auxiliary cavity part, an air supply hole is opened on the auxiliary cavity part, a one-way air valve tube is fixedly connected inside the auxiliary cavity part, the upper end of the one-way air valve tube is located in the inner cavity of the auxiliary cavity part, the bottom end of the one-way air valve tube is fixedly connected to a pressure relief valve, and a connecting pipe is threadedly connected to the pressure relief valve.

[0015] As an improvement, the connecting pipe is fixedly connected to a main shell at one end away from the pressure relief valve and located on the side wall of the clamp group, the bottom of the main shell is vertically slidably connected to a secondary shell, the bottom end of the secondary shell is provided with through holes equidistantly, the inner cavity of the secondary shell is fixedly connected to a return spring, and the top of the return spring is fixedly connected to the top wall of the inner cavity of the main shell.

[0016] As an improvement, the rotating disk includes two disk surfaces, and the two disk surfaces are driven by the same driving shaft. A cylindrical opening is opened on the detection strip B, and the inner surface of the cylindrical opening is rough.

[0017] As an improvement, the air thrust piece is made of magnetic material.

[0018] Compared with the prior art, the present invention provides an electronic parking device comprehensive testing platform, which has the following beneficial effects: 1. The present invention adopts a design in which the testing strip A is rotatably connected to the testing strip B, and a cylindrical through hole with a rough surface is provided on the friction plate and the testing strip B. When the fixing deviation detection work is carried out on the electronic parking device on the clamp group, that is, the detection work in the non-storage state, this design can play an important role, effectively avoiding the position detection error caused by the loose fixation of the electronic parking device, and the problem of rashly performing detection when the fixing of the electronic parking device is loose.

[0019] Specifically, the foldable detection rod composed of the detection strip A and the detection strip B has a special functional mechanism; that is, when encountering a loosely fixed electronic parking device, the detection rod can continue to push the electronic parking device with the cooperation of the friction plate and the cylindrical through hole with a rough surface opened on the detection strip B, until the electronic parking device reaches a state that cannot be pushed; in this process, only when the friction force is less than the moving resistance of pushing the electronic parking device, the detection strip B that was originally in the same straight line with the detection strip A will bend, and after bending and with the help of this bending action, through the mutual distance between the electric contact strip A and the electric contact strip B, the motor that drives the rotating disk can be indirectly controlled to stop driving immediately, and then, through the positional relationship between the Hall switch card and the push air plate, the fixed position of the electronic parking device at this time can be accurately determined.

[0020] It is worth mentioning that this foldable detection rod design is significantly different from the situation where an inflexible straight rod is directly used as a substitute; if an inflexible straight rod is used, the driving shaft that drives the rotating disk to rotate will often stop rotating as soon as it touches the electronic parking device, regardless of whether the electronic parking device is in a fixed loose state at this time; the bendable design adopted by the present invention can cleverly avoid the adverse effects of the loose factor on the detection, thereby ensuring the accuracy and reliability of the detection results.

[0021] At the same time, the rough surfaces on the friction plate and the detection strip B also play a role that cannot be ignored; in the process of the rotating disk rotating, thereby providing the working premise for the detection accuracy maintenance component, relying on the characteristics of this rough surface, the storage stability of the detection strip B can be fully guaranteed without the need for additional plug-in fixings; that is, when the rotating disk rotates, indirectly contributing to the transmission of gas in the main body shell, the detection strip B located on the rotating disk and stored in the detection strip A will not be moved out of the detection strip A due to the centrifugal force of the rotating disk. Such a design not only significantly improves the stability of the various components of the device during use, but also reduces the number of components, further reduces the cost of component maintenance, and lays a good foundation for the efficient operation and long-term stable use of the entire device.

[0022] 2. The present invention can improve the adaptability of the position deviation judgment component to the detection of different types of electronic parking devices through the design that the Hall switch card can be snapped onto the auxiliary cavity part; specifically, since it is known that the deviation detection is based on the rotation of the rotating disk, which drives the bendable detection rod composed of detection strips A and detection strips B, a deflection detection; when the detection rod moves to a point where it can no longer move, the power is cut off to the driving shaft of the rotating disk, and the position of the push air piece and the Hall switch card is used as the judgment standard for the detection method.

[0023] In actual application scenarios, different types of electronic parking devices differ in size and other aspects. For example, when the electronic parking device is relatively large, after it is fixed and stabilized, the above-mentioned deflection detection is carried out, and such a situation may occur: the distance that the connecting rod can move in the auxiliary cavity part will be relatively short. In order to smoothly cooperate to complete the accurate detection of such a large-sized electronic parking device, it is necessary to flexibly adjust and clamp the Hall switch card component at different positions of the auxiliary cavity part according to the actual situation, otherwise it will be impossible to achieve effective detection of different types of electronic parking devices. The present invention adopts the design that only needs to adjust the position of the Hall switch card component on the auxiliary cavity part to easily adapt to different types and sizes of electronic parking devices. The operation is extremely simple and does not require complicated tools or cumbersome steps. The detection personnel only need to simply adjust the buckle position of the Hall switch card component on the auxiliary cavity part according to the actual size of the electronic parking device, so that the detection device can quickly enter the adaptation state. It has strong versatility, greatly improves the efficiency of the detection work, and reduces the time cost of replacing different adaptation devices or adjusting complex structures.

[0024] 3. The present invention can effectively solve many problems caused by the installation position deviation in the traditional detection and fixing method through the design of the position deviation judgment component, and bring many significant benefits; it can accurately detect the position of the electronic parking device after it is fixed, avoid the situation where the position sensor perceives the wrong position information due to the fixing deviation, prevent the sensor from misjudging the distance between the brake pad and the brake disc, ensure that the electronic parking control unit can accurately adjust the braking force according to the actual situation, and greatly improve the accuracy of the results when detecting the accuracy and reliability of the position sensor; at the same time, in terms of electrical connection stability detection, the component can timely detect the position deviation of the electronic parking device, avoid the connected detection cable from being pulled or bent, eliminate poor contact caused by abnormal cable status, prevent the detected electrical parameters such as current and voltage from instantaneous jumps or interruptions, and cause long-term damage to the electrical interface, ensure the normal electrical function of the electronic parking device, eliminate the basis for erroneous judgment caused by position deviation in the detection work, thereby comprehensively ensuring the accuracy and reliability of subsequent detection work, providing strong support for high-quality detection of electronic parking devices, improving overall detection efficiency and quality, and reducing various adverse effects and cost losses caused by detection errors.

[0025] 4. The present invention uses the design of the arc-shaped groove of the 8-shaped groove to indirectly store gas for the detection accuracy maintenance component under the cooperation of the sliding block and the 8-shaped groove. As the stored gas gradually increases, its gas pressure also gradually increases. During this process, each time the 8-shaped groove and the sliding block involved in the gas storage move with the connecting rod leading the air pusher, the reaction force on the groove wall of the 8-shaped groove will gradually increase. However, due to its arc-shaped design, the force can be effectively dispersed, and the point of application of the force can be adjusted in real time to different positions of the groove wall of the 8-shaped groove during the rotation of the rotating disk. The above design can maintain a good performance state during long-term operation, reduce the cost investment caused by repair or replacement due to frequent damage of components and the impact on the continuity of detection work, and provide reliable hardware guarantee for the stable and efficient detection of electronic parking devices.

[0026] 5. The present invention can greatly improve the detection working conditions through the design of the detection accuracy maintenance component; it can effectively remove dust and other particulate impurities on the fixing table, and avoid these impurities being between the clamp and the contact surface of the electronic parking device when the electronic parking device is fixed, thereby ensuring that the clamping force of the clamp on the electronic parking device is evenly distributed, so that when detecting key mechanical performance indicators such as braking torque, the electronic parking device will not be displaced due to uneven clamping force, ensuring that the braking components maintain an ideal fitting state and pressure distribution, improving the accuracy of the braking torque detection value, and facilitating accurate judgment of the real braking ability of the electronic parking device; at the same time, it can also prevent the friction characteristics from being changed due to the influence of impurities, so that the electronic parking device will not slide when detecting high-precision positioning parameters such as internal position sensor calibration, ensuring that it is in an accurate detection position, making the signal fed back by the position sensor accurate and reliable, helping technicians to accurately control the performance of the electronic parking device, and comprehensively improving the accuracy and reliability of the entire detection process, laying a solid foundation for high-quality detection of electronic parking devices, reducing misjudgments and detection errors caused by impurity interference, and improving detection efficiency and quality.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0043] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0044] Example: Please refer to Figures 1 to 8 As shown: In order to solve the problems mentioned in the technical solution, an embodiment of the present application provides an electronic parking device comprehensive testing platform, including: a testing platform 1, a fixture group 2, and also including: a position deviation judgment component 3, a detection accuracy maintenance component 4, the position deviation judgment component 3 is located above the detection accuracy maintenance component 4.

[0045] The position deviation determination component 3 is used to detect the position of the fixed electronic parking device.

[0046] The position deviation judgment component 3 includes a rotating disk 301 rotatably connected to the clamp group 2, a detection strip A302 is fixedly connected to the rotating disk 301, a bayonet 303 is provided on the detection strip A302, a fixed column 304 is fixedly connected to the front end of the detection strip A302, a friction plate 305 is fixedly sleeved on the fixed column 304, a detection strip B306 is rotatably connected to the outer ring surface of the friction plate 305 on the fixed column 304, a position determination column 307 is fixedly connected to the clamp group 2, an electric contact strip A308 is fixedly connected to the inner surface of the detection strip A302, an electric contact strip B309 is fixedly connected to the bottom surface of the detection strip B306, an alignment mark A310 is fixedly connected to the detection strip A302, an alignment mark B311 is fixedly connected to the detection strip B306, a Hall switch card 312 is arranged below the detection strip A302, and an indicator light 313 is fixedly connected to the Hall switch card 312.

[0047] Among them: the fixture group 2 is mainly used to fix the equipment to be tested, here it is to fix the electronic parking device.

[0048] The position deviation determination component 3 is used to detect the position of the fixed electronic parking device.

[0049] The rotating disk 301 includes two disk surfaces, and the two disk surfaces are driven by the same driving shaft.

[0050] The detection strip B306 is provided with a cylindrical opening, the inner surface of which is rough and can be mainly used in conjunction with the friction plate 305 .

[0051] If the electronic parking brake fastened by the clamp assembly 2 is fixed in the correct position, the snap-in 303 on the detection bar A302 with the driving shaft of the rotating disk 301 as the rotation axis will be just snapped onto the position determination column 307 .

[0052] Only when the electrical contact strip A308 contacts the electrical contact strip B309, the driving shaft driving the rotating disk 301 will be started under the action of the main controller, thereby causing the detection strip A302 to rotate. When they are no longer in contact, the driving shaft driving the rotating disk 301 will stop rotating.

[0053] The alignment markings A310 and B311 are mainly used to assist in determining whether there is a deviation in the fixed position of the electronic parking device fastened by the clamp set 2, and whether it affects the implementation of subsequent detection.

[0054] The Hall switch clamp 312 can be clamped at different positions on the auxiliary cavity member 405 according to the scale lines engraved on the auxiliary cavity member 405 , so as to cooperate with the magnetic push air piece 404 to adapt to different types of electronic parking devices.

[0055] There is an electrical connection between the indicator light 313 and the Hall switch set in the Hall switch card 312. When the Hall switch card 312 and the air push piece 404 are on the same vertical plane, the indicator light 313 lights up, indicating that the electronic parking device fastened by the clamp group 2 is accurately fixed in position and subsequent detection work can be carried out.

[0056] For further examples, please refer to Figure 1 , Figure 2 , Figures 9 to 12 As shown: the detection accuracy maintenance component 4 is used to eliminate interference factors on the surface of the fixture group 2 to ensure the fastening ability of the fixture group 2; the detection accuracy maintenance component 4 includes an 8-shaped groove 401 opened on the rotating disk 301, a sliding block 402 is slidably connected in the 8-shaped groove 401, a connecting rod 403 is fixedly connected to the sliding block 402, and an air push piece 404 is fixedly connected to the end of the connecting rod 403 away from the sliding block 402, an auxiliary cavity part 405 is fixedly connected to the fixture group 2, a Hall switch clamp 312 is clamped on the auxiliary cavity part 405, and an air supplement hole 406 is opened on the auxiliary cavity part 405, and the auxiliary cavity part 4 05 is fixedly connected with a one-way air valve tube 407, the upper end of the one-way air valve tube 407 is located in the inner cavity of the auxiliary cavity part 405, the bottom end of the one-way air valve tube 407 is fixedly connected with a pressure relief valve 408, the pressure relief valve 408 is threadedly connected with a connecting pipe 409, the connecting pipe 409 is away from the end of the pressure relief valve 408 and is located on the side wall of the clamp group 2 and is fixedly connected with a main body shell 410, the bottom of the main body shell 410 is vertically slidably connected with a sub-shell 411, the bottom end of the sub-shell 411 is equidistantly provided with through holes 413, the inner cavity of the sub-shell 411 is fixedly connected with a return spring 412, and the top end of the return spring 412 is fixedly connected to the top wall of the inner cavity of the main body shell 410.

[0057] Wherein: the detection accuracy maintenance component 4 is used to eliminate interference factors on the surface of the clamp group 2 to ensure the fastening ability of the clamp group 2.

[0058] The sliding block 402 is slidably adapted in the 8-shaped groove 401 .

[0059] The air pusher 404 is made of magnetic material.

[0060] The gas replenishment hole 406 is mainly used to supplement the gas of the auxiliary cavity part 405 .

[0061] When the gas pressure transmitted by the one-way air valve tube 407 reaches a threshold value that the pressure relief valve 408 can withstand, the pressure relief valve 408 will release the air that was previously blocked from entering the connecting tube 409 and transmit the air to the main body shell 410 through the connecting tube 409.

[0062] The return spring 412 is mainly used for returning the auxiliary housing 411 .

[0063] The gas leaks out from the through hole 413 and acts on the surface of the clamp set 2 , thereby blowing away dust and debris particles that affect fastening from the surface of the clamp set 2 .

[0064] The working principles of all the contents in the above embodiments are as follows: in the initial state: the detection strip B306 is housed in the detection strip A302, the bayonet 303 on the detection strip A302 is not clamped on the position determination column 307, the Hall switch clamp 312 is not on the same vertical plane as the air push piece 404, and the return spring 412 is not compressed.

[0065] Before the position deviation judgment component 3 starts working, it is first necessary to use the detection accuracy maintenance component 4 to handle the interference factors on the surface of the device.

[0066] The following is the working process of the position deviation judgment component 3: It should be noted that the deviation detection is based on the deflection detection by rotating the rotating disk 301, which drives the bendable detection rod composed of the detection strip A302 and the detection strip B306; when the detection rod moves to the point where it can no longer move, the power is cut off to the driving shaft of the rotating disk 301, and the position of the push air piece 404 and the Hall switch card 312 is used as the judgment standard.

[0067] Specifically, when in use, first remove the detection strip B306 from the detection strip A302, and adjust the detection strip A302 and the detection strip B306 to be in a straight line with the cooperation of the alignment mark A310 and the alignment mark B311. At this time, the detection strip A302 and the detection strip B306 form a detection rod for detection. Further, when the detection strip A302 and the detection strip B306 are in the same straight line, the electrical contact strip A308 and the electrical contact strip B309 thereon will come into contact. At this time, the driving shaft that is electrically connected to the electrical contact strip A308 and the electrical contact strip B309 for driving the rotating disk 301 to rotate will drive the rotating disk 301 to rotate. Furthermore, when the rotating disk 301 rotates slowly, the rotating disk 301 will drive the detection rod composed of the detection strip A302 and the detection strip B306 thereon to rotate with the driving shaft as the axis. For details, please refer to the attached Figure 4 , Attachment Figure 5As the detection rod moves, the detection rod will gradually approach and contact the electronic parking device fixed by the clamp group 2. At this time, the detection rod will appear in two states: one is that the electronic parking device is in a stable and fixed state and is forced to bend; the other is that the electronic parking device is loosely fixed, and the detection rod will be pushed a certain distance and then bend; specifically, no matter which case, the detection rod that is finally bent, that is, the detection strips A302 and B306 that were originally in the same straight line, will become attached. Figure 6 In the non-linear state shown, the electrical contact strip A308 and the electrical contact strip B309 are no longer in contact, and the driving shaft driving the rotating disk 301 to rotate will stop running. At this time, the rotating disk 301 stops rotating.

[0068] Furthermore, during the period when the rotating disk 301 drives the detection rod composed of the detection strip A302 and the detection strip B306 to rotate, the rotating disk 301 can cooperate with the sliding block 402 through the 8-shaped groove 401 opened thereon to move; specifically, during the rotation of the rotating disk 301, the sliding block 402 sliding in the 8-shaped groove 401 will move with the connecting rod 403 during the rotation of the rotating disk 301, and because the connecting rod 403 and the air pusher 404 are fixedly connected, the air pusher 404 is restricted in the cavity of the auxiliary cavity part 405. Therefore, at this time, during the rotation of the rotating disk 301, the sliding block 402 in the 8-shaped groove 401 can move the connecting rod 403 to move the air pusher 404 in the cavity of the auxiliary cavity part 405.

[0069] Furthermore, when the detection rod composed of the detection strip A302 and the detection strip B306 is bent, the rotating disk 301 stops rotating, and the air push piece 404 stops moving in the cavity of the auxiliary cavity part 405; at this time, two situations may occur. First, the air push piece 404 and the Hall switch card 312 clamped on the auxiliary cavity part 405 are on the same vertical plane. At this time, the indicator light 313 electrically connected to the Hall switch card 312 is on, which indirectly shows that the fastening work of this electronic parking device meets the detection requirements; second, the air push piece 404 and the Hall switch card 312 clamped on the auxiliary cavity part 405 are not on the same vertical plane. At this time, the indicator light 313 electrically connected to the Hall switch card 312 is not on, which indirectly shows that the fastening work of this electronic parking device does not meet the detection requirements.

[0070] Furthermore, by adopting a design in which the detection strip A302 is rotatably connected to the detection strip B306, and with the cooperation of opening a cylindrical through hole with a rough surface on the friction plate 305 and the detection strip B306, this design can play an important role in carrying out fixed deviation detection work on the electronic parking device on the clamp group 2, that is, detection work in the non-storage state, and effectively avoid position detection errors caused by loose fixation of the electronic parking device, as well as the problem of rashly carrying out detection when the electronic parking device is loosely fixed.

[0071] Specifically, the foldable detection rod composed of the detection strip A302 and the detection strip B306 has a special functional mechanism; that is, when encountering a loosely fixed electronic parking device, the detection rod can continue to push the electronic parking device with the cooperation of the friction plate 305 and the cylindrical opening with a rough surface on the detection strip B306, until the electronic parking device reaches a state that cannot be pushed; in this process, only when the friction force is less than the moving resistance of pushing the electronic parking device, the detection strip B306, which was originally in the same straight line with the detection strip A302, will bend, and after bending and with the help of this bending action, through the mutual distance between the electric contact strip A308 and the electric contact strip B309, it can indirectly control the motor driving the rotating disk 301 to stop driving immediately, and then, through the positional relationship between the Hall switch card 312 and the push air plate 404, the fixed position of the electronic parking device at this time can be accurately determined.

[0072] It is worth mentioning that this foldable detection rod design is significantly different from the situation where an inflexible straight rod is directly used as a substitute; if an inflexible straight rod is used, the driving shaft that drives the rotating disk 301 to rotate will often stop rotating as soon as it touches the electronic parking device, regardless of whether the electronic parking device is in a fixed loose state at this time; the bendable design adopted by the present invention can cleverly avoid the adverse effects of the loose factor on the detection, thereby ensuring the accuracy and reliability of the detection results.

[0073] At the same time, the rough surfaces on the friction plate 305 and the detection strip B306 also play a role that cannot be ignored; in the process of the rotating disk 301 rotating, thereby providing the working premise for the detection accuracy maintenance component 4, by virtue of the characteristics of this rough surface, the storage stability of the detection strip B306 can be fully guaranteed without the need for additional plug-in fixings; that is, when the rotating disk 301 rotates, indirectly contributing to the transmission of gas in the main body shell 410, the detection strip B306 located on the rotating disk 301 and stored in the detection strip A302 will not be moved out of the detection strip A302 due to the centrifugal force of the rotating rotating disk 301. Such a design not only significantly improves the stability of the various components of the device during use, but also reduces the number of components, further reduces the cost of component maintenance, and lays a good foundation for the efficient operation and long-term stable use of the entire device.

[0074] Furthermore, by designing that the Hall switch card 312 can be snapped onto the auxiliary cavity part 405, the adaptability of the position deviation judgment component 3 to the detection of different types of electronic parking devices can be improved; specifically, since it is known that the deviation detection is based on the rotation of the rotating disk 301, which drives the bendable detection rod composed of the detection strip A302 and the detection strip B306, a deflection detection; when the detection rod moves to a point where it can no longer move, the power is cut off to the driving shaft of the rotating disk 301, and the position of the push air piece 404 and the Hall switch card 312 is used as the judgment standard for the detection method.

[0075] In actual application scenarios, different types of electronic parking devices differ in size and other aspects. For example, when the electronic parking device is relatively large, after it is fixed and stabilized, the above-mentioned deflection detection will be carried out, and the following situation may occur: the distance that the connecting rod 403 can move in the auxiliary cavity part 405 will be relatively short. In order to smoothly cooperate to complete the accurate detection of such a large-sized electronic parking device, it is necessary to flexibly adjust the Hall switch clamp 312 and clamp it at different positions of the auxiliary cavity part 405 according to the actual situation. Otherwise, it will be impossible to achieve effective detection of different types of electronic parking devices. The present invention only needs to adjust the position of the Hall switch card 312 on the auxiliary cavity part 405 to easily adapt to the design of electronic parking devices of different types and sizes. The operation is extremely simple and does not require complicated tools or cumbersome steps. The detection personnel only need to adjust the buckle position of the Hall switch card 312 on the auxiliary cavity part 405 according to the actual size of the electronic parking device to quickly make the detection device enter the adaptation state. It has strong versatility, greatly improves the efficiency of the detection work, and reduces the time cost consumed by replacing different adaptation devices or adjusting complex structures.

[0076] Please refer to the above working process Figures 1 to 8 , Fig.11 , Fig.12 .

[0077] The following is the working process of the detection accuracy maintenance component 4: Furthermore, when the detection accuracy maintenance component 4 is working, the detection strip B306 is stored in the detection strip A302, and will not affect the operation of other components when the rotating disk 301 rotates; further, through the above description, the driving shaft of the rotating disk 301 controlled by the main controller of the device drives the rotating disk 301 to rotate, and the push-air piece 404 can be indirectly moved in the inner cavity of the auxiliary cavity part 405 through the connecting rod 403. The only difference is that the rotating disk 301 will continue to rotate at this time, instead of only rotating less than one circle when the position deviation judgment component 3 is working. Under this premise, through the influence of the 8-shaped groove 401, the indirectly driven push-air piece 404 can perform linear reciprocating motion in the inner cavity of the auxiliary cavity part 405.

[0078] Furthermore, when the air pusher 404 performs linear reciprocating motion in the inner cavity of the auxiliary cavity part 405, the air replenishing hole 406 is used to replenish the gas. The gas pushed by the air pusher 404 will enter the one-way air valve tube 407, and when the gas is collected for a certain period of time, it will be released into the main shell 410 through the connecting pipe 409 under the action of the pressure relief valve 408. Under the action of the gas impact, the sub-shell 411 will move downward for a distance in the main shell 410, and at this time, the gas will leak out from the through hole 413 to act on the surface of the fixture group 2 of the detection device, so as to blow interference factors, such as dust and debris, away from the position to be fixed later.

[0079] Furthermore, through the design of the arc-shaped groove of the 8-shaped groove 401, when the detection accuracy maintenance component 4 is indirectly storing gas under the cooperation of the sliding block 402 and the 8-shaped groove 401, the stored gas is gradually increasing, and its gas pressure is also gradually increasing. In this process, each time the 8-shaped groove 401 and the sliding block 402 participating in the gas storage are moved with the connecting rod 403 and the air pusher 404, the reaction force on the groove wall of the 8-shaped groove 401 will gradually increase. However, due to its arc-shaped design, the force can be effectively dispersed, and the point of application of the force can be adjusted in real time to different positions of the groove wall of the 8-shaped groove 401 during the rotation of the rotating disk 301. The above design can maintain a good performance state during long-term operation, reduce the cost investment caused by repair or replacement due to frequent damage of components and the impact on the continuity of detection work, and provide reliable hardware guarantee for the stable and efficient development of electronic parking device detection.
