Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and in particular, to an auxiliary device for detecting a gas spring. Background Art

[0002] The front panel of a commercial vehicle is located at the front end of the commercial vehicle cab and usually has a function of being turned up to provide a maintenance space. To improve the operation convenience, an air spring is usually used as a support after the front panel is turned up, and it is ensured that the front panel can reach a certain turning-up height. Therefore, the gas spring is also one of the essential parts of the front panel of a commercial vehicle. In the design process of the gas spring for the front panel of a commercial vehicle, the theoretical calculation method is usually used to preset the turning-up height of the front panel, and through the force balance, the theoretical length and the nominal force value of the gas spring are obtained. For the inspection of the design scheme, it is necessary to conduct physical verification after the gas spring is manufactured to judge whether the front panel can be supported to the preset height.

[0003] In the actual production and use process of the front panel of a commercial vehicle, the turning-up height of the front panel often does not match the theoretical design, either higher or lower. The reason for this problem may be the weight deviation of the front panel or the actual force value deviation of the gas spring. To determine whether the force value of the gas spring meets the design requirements and whether the design value of the gas spring is reasonable, it is usually necessary to disassemble the gas spring and measure it on a laboratory pressure test bench.

It should be understood that these embodiments are provided so that the disclosure of the present application is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and thus their description will be omitted.

[0055] Combined with Figures 1 to 5 、 Figure 7 As shown, according to a specific embodiment of the present application, an air spring detection auxiliary device is provided.

[0056] Specifically, as Figure 1 、 Figure 7As shown in the figure, the air spring detection auxiliary device includes a housing assembly 10 and a connection assembly 20. The housing assembly 10 has a receiving cavity 100 with an open end, and a tension and compression gauge 1 is arranged in the receiving cavity 100. The housing assembly 10 has a first connection end 13. One end of the connection assembly 20 extends into the receiving cavity 100 and contacts the measuring head of the tension and compression gauge 1, and the other end of the connection assembly 20 is provided with a second connection end 21. When the air spring detection auxiliary device is in the detection state, the air spring detection auxiliary device replaces the air spring 2, and the first connection end 13 is detachably connected to one of the front outer panel 3 and the vehicle body 4, and the second connection end 21 is detachably connected to the other of the front outer panel 3 and the vehicle body 4 to detect the tensile and compressive force value between the front outer panel 3 and the vehicle body 4. Wherein, a first position at the connection between the first connection end 13 and one of the front outer panel 3 or the vehicle body 4 is a second position at the connection between the first end of the air spring 2 and one of the front outer panel 3 or the vehicle body 4, and a third position at the connection between the second connection end 21 and the other of the front outer panel 3 or the vehicle body 4 is a fourth position at the connection between the second end of the air spring 2 and the other of the front outer panel 3 or the vehicle body 4.

[0057] Applying the technical solution of this embodiment, a housing assembly 10 is provided for the tension and compression gauge 1. The housing assembly 10 has a receiving cavity 100, and the tension and compression gauge 1 is arranged in the receiving cavity 100. The connection assembly 20 extends into the receiving cavity 100 and contacts the measuring head of the tension and compression gauge 1. When the spring detection auxiliary device is in the detection state, the spring detection auxiliary device is arranged between the front outer panel 3 and the vehicle body 4 of the vehicle by means of the connection assembly 20 and the housing assembly 10 instead of the air spring 2. The required tensile and compressive force value between the front outer panel 3 and the vehicle body 4 can be transmitted to the tension and compression gauge 1 through the connection assembly 20. Furthermore, the actual force value of the air spring 2 can be obtained by reading the reading on the tension and compression gauge 1, and then the theoretical design deviation of the air spring 2 can be judged.

[0058] It should be noted that when the air spring detection auxiliary device is in the detection state, the device is designed to be able to directly replace the original vehicle's air spring 2 to accurately measure the tensile and compressive force value between the front outer panel 3 and the vehicle body 4. The connection position where the first connection end 13 is connected to one of the front outer panel 3 or the vehicle body 4 is the connection position where the air spring 2 replaced by the first connection end 13 is connected to the corresponding front outer panel 3 or the vehicle body 4; the connection position where the second connection end 21 is connected to the other of the vehicle body 4 or the front outer panel 3 is the connection position where the air spring 2 replaced by the second connection end 21 is connected to the other of the corresponding vehicle body 4 or the front outer panel 3. That is, the first connection position of the first connection end 13 is placed at the second connection position of the air spring 2, and the third connection position of the second connection end 21 is placed at the fourth connection position of the air spring 2, so as to realize the replacement of the air spring 2 by the air spring detection auxiliary device, and enable the air spring detection auxiliary device to simulate the actual working state of the air spring on the vehicle, thereby accurately measuring the required supporting force between the front outer panel 3 and the vehicle body 4 in the current state by using a portable tensile and compressive force meter, and further verifying whether the design of the air spring is reasonable, or judging the specific reasons for the unsatisfactory front lift height. This design not only simplifies the detection process, shortens the detection cycle, but also improves the convenience and efficiency of detection, and has important practical value for the on-site detection and problem diagnosis of the front air spring of commercial vehicles.

[0059] Specifically, the height of a part of the housing assembly 10 is adjustable relative to another part of the housing assembly 10. Such a setting enables the distance between different structures of the housing assembly 10 itself to be relatively adjustable, ensuring that the air spring detection auxiliary device can be applicable between the front outer panel 3 and the vehicle body 4 of different vehicles in the use or actual working state, simulating the actual working state of the air spring 2, thereby ensuring the accuracy and reliability of the measurement. At the same time, it also improves the versatility and flexibility of the air spring detection auxiliary device, meeting the requirements of on-site rapid detection.

[0060] It should be noted that the distance between different components of the housing assembly 10 can be adjusted by means of a telescopic rod, thread, gear rack, air pressure or hydraulic cylinder. Preferably, the housing assembly 10 is adjusted in height by a sliding adjustment method.

[0061] Furthermore, as Figure 1 、 Figure 4As shown, the housing assembly 10 includes a housing body 11 and a lower connecting rod 12. The housing body 11 has a receiving cavity 100. One end of the lower connecting rod 12 is connected to the housing body 11, and the other end of the lower connecting rod 12 forms a first connection end 13. Among them, along the height direction of the housing body 11, the lower connecting rod 12 is slidably arranged relative to the housing body 11. The lower connecting rod 12 is connected to the housing body 11, and the other end forms a first connection end 13 for docking with the connection point of the front outer panel of the vehicle to be measured or the vehicle body. Along the height direction of the housing body 11, the lower connecting rod 12 is designed to be able to slide relative to the housing body 11, which means that the lower connecting rod 12 and the housing body 11 can move relatively up and down within a certain range to adapt to the height difference of the gas spring 2 or the front outer panel 3 of different vehicles. By sliding adjustment of the lower connecting rod 12, the position of the first connection end 13 can be changed to adapt to the gas spring 2 with different installation heights, improving the flexibility and measurement range of the gas spring detection auxiliary device, being able to adapt to the detection requirements of the gas spring 2 at different installation positions, and ensuring the accuracy of measurement.

[0062] Further, as Figure 3 , Figure 4 shown, the first connection end 13 is detachably connected to the lower connecting rod 12. By adopting a detachable connection method between the first connection end 13 and the lower connecting rod 12, the first connection end 13 can be replaced according to needs to adapt to different types of gas spring brackets, improving the versatility and adaptability of the gas spring detection auxiliary device and being able to be applied to the detection of various types of gas springs 2.

[0063] Specifically, as Figure 3As shown in the figure, a first connection end 13 is provided with a first connection assembly 130. The first connection assembly 130 includes a first ball wrist 131, a first limiting member 132, and a first ball head 133. The first ball wrist 131 is arranged at the top end of the lower connecting rod 12 away from the housing body 11. The lower connecting rod 12 is movably connected to the front outer panel 3 and the vehicle body 4 through the first ball wrist 131. The first limiting member 132 is detachably arranged on the first ball wrist 131. The first limiting member 132 is at least used to limit the circumferential movement of the first ball wrist 131 along the lower connecting rod 12. The first ball head 133 has a first connection section connected to one of the front outer panel 3 and the vehicle body 4, and the first ball head 133 has a first ball head section cooperatively connected to the first ball wrist 131. By integrating the first connection assembly 130, the first connection end 13 realizes a flexible and stable connection with the vehicle front outer panel 3 and the vehicle body 4. The first ball wrist 131 can provide a spherical joint, enabling the lower connecting rod 12 to freely move within a certain angle range between the front outer panel 3 or the vehicle body 4, which helps the air spring detection auxiliary device to automatically adjust to the best detection posture when facing different vehicle models and the layouts of the air springs 2, ensuring the accuracy of measurement and the universal applicability of the tool. The first limiting member 132 can limit the circumferential movement of the first ball wrist 131 along the lower connecting rod 12, that is, prevent the first ball wrist 131 from rotating uncontrollably. Through the locking function of the first limiting member 132, the position of the first ball wrist 131 can be fixed as needed to ensure the stability of the connection end during the detection process and avoid measurement errors caused by accidental movement. The design of the first ball head 133 adopts a cooperation method of a ball head and a ball wrist, allowing the air spring detection auxiliary device to achieve a stable connection even at a non-facing angle when connected to the vehicle body 4 or the front outer panel 3. The cooperation between the first ball head section and the first ball wrist 131 ensures that the connection between the detection tool and the vehicle components is not only stable but also has good adaptability.

[0064] In an embodiment of the present application, the first connection section of the first ball head 133 is a threaded stud, the first ball head section of the first ball head 133 is a spherical structure that cooperates with the first ball wrist 131. The first ball head section ensures the connection stability between the first ball head section and the first ball wrist 131 through a limiting member (such as a retaining ring or a snap ring), and the first connection section is connected to the air spring bracket on the front outer panel 3 or the vehicle body 4 through the stud.

[0065] Furthermore, the second connection end 21 is detachably connected to the connection assembly 20. By adopting a detachable connection method between the second connection end 21 and the connection assembly 20, the second connection end 21 can be replaced as needed to adapt to different types of air spring brackets, improving the versatility and adaptability of the air spring detection auxiliary device and enabling it to be applied to the detection of various types of air springs 2.

[0066] Specifically, as Figure 2As shown, the second connection end 21 is provided with a second connection assembly 210. The second connection assembly 210 includes a second ball wrist 211, a second limiting member 212, and a second ball head 213. The second ball wrist 211 is disposed at the top of the connection assembly 20 away from the housing assembly 10. The connection assembly 20 is movably connected to the front outer panel 3 and the vehicle body 4 through the second ball wrist 211. The second limiting member 212 is detachably disposed on the second ball wrist 211. The second limiting member 212 is at least used to limit the circumferential movement of the second ball wrist 211 along the connection assembly 20. The second ball head 213 has a second connection section connected to one of the front outer panel 3 and the vehicle body 4, and the second ball head 213 has a second ball head section cooperatively connected to the second ball wrist 211. Through the spherical connection of the second ball wrist 211 and the second ball head 213, the flexibility and stability of the connection are achieved. The setting of the second limiting member 212 ensures the reliability of the connection, prevents accidental movement during the measurement process, improves the measurement accuracy and reliability of the gas spring detection auxiliary device, can stably connect to the front outer panel 3 and the vehicle body 4, and ensures the accuracy of the measurement. The second ball wrist 211 is a spherical joint, which can enable the connection assembly 20 to freely rotate within a certain angle range in three-dimensional space with the vehicle components, ensuring that even under complex or non-standard installation conditions, the gas spring detection auxiliary device can automatically adjust to the most suitable detection angle and improve the detection accuracy. The second limiting member 212 can limit the circumferential movement of the second ball wrist 211 along the connection assembly 20, preventing unnecessary rotation of the connection assembly during the detection process and affecting the measurement of the force value. The second connection section is used to be directly fixed on the vehicle component. The other part is the second ball head section cooperatively connected to the second ball wrist 211. Through the cooperation between the ball head section and the ball wrist, it is ensured that the detection tool can be firmly fixed on the vehicle even in the case of non-right-angle connection for accurate force value detection.

[0067] Further, as Figure 2 , Figure 4 shown, an installation hole 14 is opened at one end of the housing body 11 close to the connection assembly 20. At least part of the connection assembly 20 passes through the installation hole 14 and extends into the accommodation cavity 100 to contact the measuring head of the pull and pressure gauge 1. Among them, a flange 22 is provided at one end of the connection assembly 20 close to the housing body 11. The flange 22 is at least used to limit the circumferential movement of the connection assembly 20. Through the setting of the installation hole 14 and the flange 22, it is ensured that the connection assembly 20 contacts the measuring head of the pull and pressure gauge 1 stably, prevents circumferential movement during the measurement process, thereby affecting the accuracy of the measurement, improves the measurement accuracy and reliability of the gas spring detection auxiliary device, can stably connect to the pull and pressure gauge 1, and ensures the accuracy of the measurement.

[0068] In this embodiment, the wide plane of the flange 22 can increase the contact area between the connecting component 20 and the housing body 11, thereby improving the stability and support strength of the entire structure, and preventing structural deformation or damage caused by excessive force values during the detection process; it can also make the installation and disassembly process of the connecting component 20 more intuitive and convenient. Usually, tools are used to tighten or loosen through the edge of the flange, without the need to operate deep inside the housing; at the same time, the flange 22 may also play a sealing role, preventing external dust or impurities from entering the accommodation cavity 100, protecting the pull-pressure gauge and other precision components from contamination, and also reducing the potential damage to the measuring head caused by collision or vibration.

[0069] Further, as Figure 4 , Figure 5 shown, along the length extension direction of the housing assembly 10, sliding grooves 110 are provided on the opposite sides of the housing body 11 close to the lower connecting rod 12. The lower connecting rod 12 is slidably connected to the housing assembly 10 through the sliding grooves 110. Among them, the lower connecting rod 12 has a movable state of sliding relative to the sliding grooves 110, and the lower connecting rod 12 has a locked state of locking relative to the sliding grooves 110. Among them, a locking knob 120 is provided on the side wall of the sliding groove 110, and the lower connecting rod 12 is switched between the movable state and the locked state through the locking knob 120. Through the settings of the sliding grooves 110 and the locking knob 120, the length adjustment and locking functions of the lower connecting rod 12 are realized to meet the detection requirements of different vehicle models and gas springs 2. Through the switching between the movable state and the locked state of the lower connecting rod 12, in the movable state, the lower connecting rod 12 can freely slide in the sliding grooves 110, and the extended length of the lower connecting rod 12 can be adjusted by manually pushing and pulling or using auxiliary tools such as wrenches and screwdrivers to match the specific situation of the currently measured vehicle; when the lower connecting rod 12 is adjusted to the required position, the locking knob 120 can be tightened to press or clamp the lower connecting rod 12, thereby restricting its sliding in the sliding grooves 110 and ensuring that the length of the lower connecting rod does not change during the detection process.

[0070] In an exemplary embodiment of the present application, as Figure 4 shown, scale marks are also provided on the side wall of the sliding groove 110. The scale marks are used to read the extended length of the gas spring detection auxiliary device. Through the setting of the scale marks, the extended length of the lower connecting rod 12 is intuitively displayed, and the scale can also be set to the length of the gas spring 2 replaced by the gas spring detection auxiliary device, so as to further judge whether the designed length of the gas spring 2 meets the theoretical length value.

[0071] Further, as Figure 4 , Figure 5As shown, the lower connecting rod 12 includes a support rod 121 and a third limiting member 122. There are two support rods 121, and the two support rods 121 are slidably connected to the housing body 11 through a chute 110; the third limiting member 122 is arranged on the support rod 121, and at least a part of the support rod 121 extends into the chute 110 through the third limiting member 122. Through the arrangement of the support rod 121 and the third limiting member 122, the length adjustment and positioning functions of the lower connecting rod 12 are realized, ensuring the stability during the measurement process. Through the positioning function of the third limiting member 122, the stability during the measurement process is ensured.

[0072] In this embodiment, the lower connecting rod 12 can not only flexibly adapt to various detection scenarios, ensure the force value balance and stable connection during the detection process, but also adapt to gas springs or front outer panels of different sizes by adjusting the length of the support rod 121, thereby improving the versatility and operation convenience of the gas spring detection auxiliary device. In practical applications, according to the actual flipping height of the vehicle front panel, the length of the lower connecting rod 12 can be quickly adjusted to ensure that the detection tool can accurately simulate the working state of the gas spring 2 and perform accurate force value measurement. At the same time, the presence of the third limiting member 122 also ensures the fixation of the position of the lower connecting rod during the measurement process, avoiding measurement errors caused by improper operation or external interference, and improving the accuracy and reliability of the detection results.

[0073] In an embodiment of the present application, as Figure 5 shown, anti-slip patterns are provided on the support rod 121. Through the setting of the anti-slip patterns, the friction between the support rod 121 and the housing assembly 10 is increased, preventing accidental sliding during the adjustment process and thus affecting the measurement accuracy.

[0074] The present application also provides a preferred embodiment of a gas spring detection auxiliary device. As Figure 6 shown, Figure 6 is a working state diagram of the gas spring 2 disposed between the front outer panel 3 and the vehicle body 4. As Figure 7 shown, Figure 7 is a working state diagram of the gas spring detection auxiliary device used to replace the position of the gas spring 2. Through this tool, using a portable hand-held pull-pressure gauge, the design scheme of the gas spring 2 can be quickly verified to confirm whether the design value of the gas spring 2 is reasonable. At the same time, it can also be used to determine the cause of the problem when the front panel lifting height does not meet the requirements.

[0075] Specifically, the gas spring detection auxiliary device includes a connection component 20, a housing component 10, a locking knob 120, etc. The connection component 20 includes a second connection end 21 and an upper support rod. The second connection end 21 has a second connection component 210. The second connection component 210 includes a second ball head 213 with an external thread, a retaining ring, a second limiting member 212, and a second ball wrist 211 with an internal thread. The second connection component 210 is used to connect with the gas spring bracket on the front outer panel 3. One end of the upper support rod has an external thread and can be screwed with the second ball wrist, and the other end has a flange 22 and contacts with the tension and measurement head.

[0076] The housing component 10 includes a housing body 11 and a lower connecting rod 12. The housing body 11 has a receiving cavity 100 for installing a tension and pressure gauge. An installation hole 14 is provided on the housing body 11, and an observation hole is opened on the back for easy reading and operation when the tension and pressure gauge is installed in reverse; two sliding grooves 110 are provided on both sides of the housing body 11 for installing the lower connecting rod 12. At the same time, the sliding grooves 110 are provided with readable and locking knob assembly holes for adjusting the height of the lower connecting rod 12. The lower connecting rod 12 includes a support rod 121 and a third limiting member 122. The support rod 121 is two parallel support rods with anti-slip patterns on it, which can be inserted into the sliding grooves 110 on the housing body 11. The other end is a round rod with a thread and can be connected with the first ball wrist 131 on the first connection end 13; the third limiting member 122 needs to be assembled after the support rod 121 is inserted into the sliding groove 110 to prevent the support rod 121 from slipping out of the sliding groove 110. At the same time, the third limiting member 122 has a "one" - shaped groove for scale indication; the structure of the first connection component 130 is the same as that of the second connection component 210 and is used to connect with the gas spring bracket on the vehicle body 4.

[0077] The gas spring detection auxiliary device is used in cooperation with a portable tension and pressure gauge to quickly measure the supporting force required to support the front outer panel 3 to the designed height, and can be used for verifying the design scheme and analyzing problems of the gas spring 2.

[0078] From the above description, it can be seen that this embodiment has the following beneficial effects:

[0079] 1) The gas spring detection auxiliary device is used in cooperation with a portable tension and pressure gauge to quickly measure the supporting force required to support the front panel to the designed height, and can be used for checking the design scheme (length and force value) of the gas spring.

[0080] 2) When there is a problem that the lifting height of the front panel is inconsistent with the design scheme, the length of the tool can be adjusted to be the same as the current state of the gas spring, and the gas spring is replaced and installed on the vehicle body. The current force value can be measured by a portable tension and pressure gauge, which is the actual force value of the gas spring and is used to judge the deviation from the theoretical design.

[0081] 3) Quick-release ball joint structures are provided at both ends of the gas spring detection auxiliary device. If the vehicle to be measured only has a bracket, the thread of the ball head connection section can be used to connect with the bracket for measurement; if the vehicle to be measured is equipped with a gas spring 2, the ball bowl part of the original vehicle gas spring 2 can be disassembled, and the ball head can be retained on the bracket. At the same time, the ball heads at both ends of the gas spring detection auxiliary device are removed, and the ball bowl is quickly connected to the ball head on the bracket to improve the convenience of use.

[0082] 4) An adjustable chute 110, a locking knob 120 and a scale are provided on the housing body 11, which is convenient for adjusting the length dimension of the gas spring detection auxiliary device to meet the requirements of different vehicle models.

[0083] For the sake of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" and the like can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device.
