Description

Technical Field

[0001] The present invention relates to the technical field of parachute acceleration monitoring devices, and particularly to a dynamic test acceleration monitoring device. Background Art

[0002] Acceleration monitoring devices are widely used in parachutes, covering aspects such as ultimate load testing, performance monitoring, safety control, parachute protection, and recovery systems, providing important technical support for the design, testing, and use of parachutes. Existing acceleration detection devices can be divided into 4-channel acceleration monitoring devices, 8-channel acceleration monitoring devices, and 24-channel acceleration monitoring devices, which support high-frequency sampling rates and can accurately record rapidly changing impact signals. Usually, 24-channel acceleration monitoring devices are used for detection and information collection.

[0003] During the acceleration monitoring work of a 24-channel parachute acceleration monitoring device, a large amount of data needs to be monitored and analyzed to ensure the integrity and accuracy of the data. Moreover, the 24 wiring ports of the 24-channel acceleration monitoring device are all set on one side of the device. Therefore, after all the cables are inserted, since there are many cables connected to the device, it is very easy for the operator to accidentally trip over the cables during work, causing the circuit to break. When any one group of cables of the 24-channel parachute acceleration monitoring device suddenly disconnects, it will cause the loss of parachute monitoring data, hardware damage to the monitoring device, and system stability at multiple levels. Although the prior art has designed a way to lock the cable connector and the wiring socket to prevent disconnection, when the cable is instantaneously dragged by an external force, the instantaneous dragging force is likely to exceed the tensile limit of the wire filaments inside the cable and the welding points at the joints, thereby causing the solder joints to break, and still easily causing disconnection when subjected to an instantaneous dragging force. In addition, the naturally hanging cables will block the outside of the device. Due to the high-density integration of the device channel circuit and the accumulation of power consumption, a large amount of heat will be generated. Therefore, the cables naturally hanging outside the device will prevent the air from flowing and cause the heat to accumulate, ultimately leading to an increase in the device temperature, and then easily causing abnormal functions of the electronic circuit.

[0004] Therefore, a dynamic test acceleration monitoring device is proposed. Summary of the Invention

[0005] The object of the present invention is to provide a dynamic test acceleration monitoring device, which solves the problems that the cable connected to the speed monitoring device is numerous, the internal wire of the cable is easily disconnected from the welding point at the joint when subjected to an instantaneous dragging force, and the naturally hanging cable will block the outside of the device, resulting in an increase in the device temperature. After pulling out the telescopic frame and starting the motor, the clamping component will clamp the cable, and at the same time, the lifting component will create a bending buffer zone for the cable, which can prevent the wire of the cable from breaking at the welding point of the joint when the cable is subjected to a large dragging force. And the telescopic plate frame after being pulled out will leave a gap between the cables, facilitating ventilation and heat dissipation.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A dynamic test acceleration monitoring device includes a chassis, a socket provided on the outside of the chassis, a cable plugged into the socket, and further includes a telescopic plate frame slidably connected to one side of the chassis, a driving component provided on the telescopic plate frame, a clamping component provided inside the telescopic plate frame, a lifting component provided on the inner side of the telescopic plate frame, and a limiting component provided on the outside of the chassis; the limiting component limits the position of the telescopic plate frame after it is pulled out; the driving component can drive the lifting component to rise to make the cable bend, and at the same time, the driving component will also drive the clamping component to close to clamp the cable. After the lifting component rises to the top, it will stop rising, and the driving component will drive the clamping component to continue to operate to clamp the cable.

[0008] Preferably, a through hole is provided on the telescopic plate frame, and a rectangular card slot is further provided around the through hole; the number of through holes is the same as that of the sockets and their positions correspond to each other, and the diameter of the through hole is larger than the diameter of the socket; in the initial state, the telescopic plate frame is in a fitting state with the chassis. After the cable passes through the through hole and is plugged into the socket, the telescopic plate frame can be pulled out. At this time, the telescopic plate frame will lift the cable that naturally hangs on the side wall of the chassis, leaving a gap between the cables.

[0009] Preferably, the driving component includes a motor fixedly connected to the telescopic plate frame, two groups of rotating rods rotatably connected inside the telescopic plate frame, multiple groups of spiral threads provided on the rotating rods, a gear one fixedly connected to both ends of the upper rotating rod, a gear two fixedly connected to one end of the lower rotating rod, and a gear three fixedly connected to the output shaft of the motor; the rotating rods are located between the upper and lower through holes; the gear three is located between the gear one and the gear two, and the diameter of the gear three is smaller than that of the gear one and the gear two and meshes with the gear one and the gear two at the same time; when the motor is driven, the gear three will drive the gear two and the gear one to rotate in the same direction, thereby driving the two groups of rotating rods to rotate in the same direction.

[0010] Preferably, the clamping assembly includes multiple sets of retractable rods slidably connected within the telescopic plate frame, clamping blocks fixedly connected to the retractable rods, stop rods fixedly connected to the clamping blocks, first hinge rods fixedly connected to the retractable rods, second hinge rods fixedly connected to the retractable rods, hinge blocks rotatably connected between the first and second hinge rods, push plates fixedly connected to the hinge blocks, retractable plates slidably connected to both sides of the push plates, and a first elastic member connected between the two retractable plates; when the two rotating rods rotate, they will drive the retractable rods on both sides of each through - opening to approach each other, thereby driving the clamping blocks to approach each other, and at the same time driving the upper and lower push plates to approach each other, finally clamping the cable between the clamping blocks and the push plates, and the stop rods can prevent the cable from getting stuck in the gap between the push plates and the clamping blocks.

[0011] Preferably, the retractable rods are located on both sides of the through - opening, the clamping blocks are fitted with the rectangular card slots on the left and right sides of the through - opening, and when the retractable plates open, they will be fitted with the rectangular card slots on the upper and lower sides of the through - opening; the retractable rods are threadedly connected to the spiral threads on the rotating rods, and the spiral thread patterns at adjacent sets of retractable rods are opposite. When the motor drives the rotating rod to rotate, the spiral threads with opposite patterns on the rotating rod will drive the retractable rods on both sides of the through - opening to approach each other.

[0012] Preferably, the ends of the clamping blocks and the push plates located inside the telescopic plate frame are flush with the outer surface of the telescopic plate frame; the ends of the clamping blocks and the push plates close to the outside of the telescopic plate frame extend out of the telescopic plate frame, which can increase the clamping area of the cable, prevent damage to the cable caused by too small a clamping area and excessive force concentration, and the extending distance of the clamping blocks is greater than that of the push plates, which can prevent the stop rods from being blocked by the push plates when the clamping blocks approach each other.

[0013] Preferably, a support rod is fixedly connected to the bottom of the push plate, vertical grooves are provided at the rectangular card slots on the upper and lower sides of the through - opening, and the support rod is slidably connected to the vertical grooves. When the retractable rods approach each other and drive the push plate to rise, the support rod can prevent the push plate from rotating and deflecting, ensuring that the push plate is in a straight - up - and - down state.

[0014] Preferably, the lifting assembly includes two sets of slide rails fixedly connected to the inside of the telescopic plate frame, a toothed plate slidably connected to the slide rails, a second elastic member installed at the bottom of the slide rails, a connecting block fixedly connected to the toothed plate, a lifting frame fixedly connected between the connecting blocks, and a third elastic member installed between the connecting block and the lifting frame; the two slide rails are respectively located at the two sets of gear - ones, and the toothed plate meshes with the gear - one; when the gear - one rotates, it will drive the toothed plate to rise, and then drive the lifting frame to rise, so that the cable rises and bends. When the gear - one rotates to abut against the bottom teeth of the toothed plate, the toothed plate will no longer be able to rise (this is when the toothed plate rises to the highest point), and at this time the gear - one will continue to rotate until it drives the clamping blocks to clamp the cable.

[0015] Preferably, a receiving groove matching the shapes of the lifting frame and the sliding rail is further formed in the chassis. When the telescopic plate frame is entirely attached to the chassis, the lifting frame and the sliding rail can enter the receiving groove, so that the telescopic plate frame is completely attached to the chassis, reducing the occupied area.

[0016] Preferably, the limiting component includes a housing sleeve fixedly connected to the outside of the chassis, a limiting rod telescopically connected to the housing sleeve, a fourth elastic member sleeved outside the limiting rod, and a limiting hole formed in the rod body part of the telescopic plate frame. When the telescopic plate frame is fully extended, the limiting rod will be pushed by the fourth elastic member and inserted into the limiting hole, thereby limiting the position of the telescopic plate frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. When the telescopic plate frame is fully extended, the motor can be started. The output shaft of the motor will drive the third gear to rotate, and then drive the two rotating rods to rotate in the same direction. Since the spiral thread patterns at the adjacent two closing rods are opposite, when the two rotating rods rotate, they will drive the closing rods on both sides of each through hole to approach each other, thereby driving the two clamping blocks on both sides of the through hole to approach each other. At the same time, the inner angles of the first hinge rod and the second hinge rod will gradually become smaller and approach each other, thereby driving the upper and lower two push plates to approach each other. Finally, the cable is clamped between the clamping block and the push plate, preventing the internal wire filaments of the cable from breaking at the welding point of the joint when the cable is instantaneously dragged by an external force. Moreover, the ends of the clamping block and the push plate extending out of the telescopic plate frame towards the outside can increase the clamping area of the cable, preventing damage to the cable due to excessive concentration of force on a too small clamping area.

[0019] 2. At the beginning of the clamping action of the cable by the motor-driven clamping component of the present invention, the first gear will drive the toothed plate to rise, thereby driving the lifting frame to rise, driving the cable to rise and bend. After the toothed plate rises to the highest point, the first gear will continue to rotate until the clamping block clamps the cable. And under the action of the fourth elastic member, when the cable is clamped and then subjected to an excessive dragging force and slides relative to the clamping block, the bent part will be straightened, thereby driving the lifting frame to move downward relative to the toothed plate against the elastic force of the fourth elastic member, providing a buffer zone for the cable, and preventing the cable from directly generating a pulling force at the connection head when subjected to a large instantaneous dragging force, resulting in the disconnection of the welding point between the cable and the connection head.

[0020] 3. After the telescopic plate frame of the present invention is fully extended, the limiting rod will be inserted into the limiting hole under the thrust of the elastic member four, thereby limiting the position of the telescopic plate frame. At this time, the telescopic plate frame will lift the cable that naturally hangs down along the side wall of the chassis, leaving a gap between the cables, which is convenient for ventilation and heat dissipation, and prevents the cable that naturally hangs down from blocking the outside of the chassis and causing the temperature of the equipment to rise. Moreover, after the clamping block and the push plate clamp the cable, there will be a gap between the clamping block and the push plate and the through hole, allowing air to pass through the telescopic plate frame, further increasing the air circulation.

DETAILED DESCRIPTION OF THE INVENTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 9 , the present invention provides a dynamic test acceleration monitoring device, and the technical solution is as follows:

[0033] As an implementation manner of the present invention, referring to Figures 1 to 3 , a dynamic test acceleration monitoring device includes a chassis 1, a socket 11 arranged outside the chassis 1, a cable 12 plugged into the socket 11, and further includes a telescopic plate frame 2 slidably connected to one side of the chassis 1, a driving component 3 arranged on the telescopic plate frame 2, a clamping component 4 arranged inside the telescopic plate frame 2, a lifting component 5 arranged inside the telescopic plate frame 2, and a limiting component 6 arranged outside the chassis 1; when in use, after the cable 12 is plugged into the socket 11, the telescopic plate frame 2 can be pulled open, and the position of the pulled-open telescopic plate frame 2 will be limited by the limiting component 6, and then the driving component 3 can be operated to work. The driving component 3 will drive the lifting component 5 to rise to bend the cable 12, and at the same time, the driving component 3 will also drive the clamping component 4 to close to clamp the cable 12. After the lifting component 5 rises to the top, it will stop rising, and the driving component 3 will drive the clamping component 4 to continue to operate to clamp the cable 12.

[0034] As an implementation manner of the present invention, referring to Figure 1 , the telescopic plate frame 2 is provided with a through hole 21, and a rectangular card slot 22 is further arranged around the through hole 21; the number of the through holes 21 is the same as that of the sockets 11 and their positions correspond to each other. The diameter of the through hole 21 is larger than that of the socket 11 to facilitate the plugging of the cable 12; in the initial state, the telescopic plate frame 2 is in a fitting state with the chassis 1. When plugging in the cable 12, the cable 12 can be passed through the through hole 21 and plugged into the socket 11, and then the telescopic plate frame 2 is pulled open. At this time, the telescopic plate frame 2 will lift the cable 12 that naturally hangs down along the side wall of the chassis 1, so that there is a gap between the cables 12, which is convenient for ventilation and heat dissipation.

[0035] As an implementation manner of the present invention, referring to Figure 3, the driving assembly 3 includes a motor 31 fixedly connected to the telescopic plate frame 2, two groups of rotating rods 32 rotatably connected inside the telescopic plate frame 2, multiple groups of spiral threads 33 provided on the rotating rods 32, a first gear 34 fixedly connected to both ends of the upper rotating rod 32, a second gear 35 fixedly connected to one end of the lower rotating rod 32, and a third gear 36 fixedly connected to the output shaft of the motor 31; the rotating rod 32 is located between the upper and lower through ports 21; the third gear 36 is located between the first gear 34 and the second gear 35, and the diameter of the third gear 36 is smaller than that of the first gear 34 and the second gear 35 and meshes with the first gear 34 and the second gear 35 simultaneously; when the motor 31 is driven, the third gear 36 will drive the second gear 35 and the first gear 34 to rotate in the same direction, thereby driving the two groups of rotating rods 32 to rotate in the same direction.

[0036] As an implementation manner of the present invention, referring to Figures 4 to 6 , the clamping assembly 4 includes multiple groups of retractable rods 41 slidably connected inside the telescopic plate frame 2, clamping blocks 42 fixedly connected to the retractable rods 41, blocking rods 43 fixedly connected to the clamping blocks 42, a first articulated rod 44 fixedly connected to the retractable rods 41, a second articulated rod 45 fixedly connected to the retractable rods 41, an articulated block 46 rotatably connected between the first articulated rod 44 and the second articulated rod 45, a push plate 47 fixedly connected to the articulated block 46, retractable plates 48 slidably connected to both sides of the push plate 47, and a first elastic member 49 connected between the two retractable plates 48; when the motor 31 drives the two groups of rotating rods 32 to rotate, the two groups of rotating rods 32 will drive the retractable rods 41 on both sides of each through port 21 to approach each other, thereby driving the clamping blocks 42 to approach each other. At the same time, the inner angles of the first articulated rod 44 and the second articulated rod 45 will gradually become smaller and approach each other, thereby driving the upper and lower push plates 47 to approach each other. Finally, the cable 12 is clamped between the clamping block 42 and the push plate 47, and the blocking rod 43 can prevent the cable 12 from getting stuck in the gap between the push plate 47 and the clamping block 42.

[0037] As an implementation manner of the present invention, referring to Figure 4 and Figure 5, the closing rods 41 are located on both sides of the passing port 21. The clamping blocks 42 are fitted with the rectangular clamping grooves 22 on the left and right sides of the passing port 21. When the clamping blocks 42 are clamped with the rectangular clamping grooves 22, it is the maximum distance for the closing rods 41 to move towards both ends of the passing port 21. When the shrinking plate 48 opens, it will be fitted with the rectangular clamping grooves 22 on the upper and lower sides of the passing port 21. When the closing rods 41 approach each other, they will drive the shrinking plate 48 to gradually tighten into the pushing plate 47 against the elastic force of the first elastic member 49. After the pushing plate 47 and the clamping blocks 42 completely clamp the cable 12, the shrinking plate 48 will also be completely retracted into the pushing plate 47. The closing rods 41 are threadedly connected with the spiral threads 33 on the rotating rod 32, and the spiral thread patterns 33 at adjacent groups of closing rods 41 are opposite. Therefore, when the motor 31 drives the rotating rod 32 to rotate, the spiral threads 33 with opposite patterns on the rotating rod 32 will drive the closing rods 41 on both sides of the passing port 21 to approach each other.

[0038] As an implementation manner of the present invention, referring to Figure 4 and Figure 5 , one ends of the clamping blocks 42 and the pushing plate 47 located inside the telescopic plate frame 2 are flush with the outer surface of the telescopic plate frame 2, so that they can be completely fitted when the telescopic plate frame 2 is attached to the chassis 1. One ends of the clamping blocks 42 and the pushing plate 47 close to the outside of the telescopic plate frame 2 extend out of the telescopic plate frame 2, which can increase the clamping area of the cable 12, prevent damage to the cable 12 caused by too small clamping area and too concentrated force, and the extending distance of the clamping blocks 42 is greater than that of the pushing plate 47, which can prevent the blocking rod 43 from being blocked by the pushing plate 47 when the clamping blocks 42 approach each other.

[0039] As an implementation manner of the present invention, referring to Figures 4 to 6 , a support rod 471 is fixedly connected to the bottom of the pushing plate 47. Vertical grooves 472 are formed at the rectangular clamping grooves 22 on the upper and lower sides of the passing port 21. The support rod 471 is slidably connected with the vertical grooves 472. When the closing rods 41 approach each other and drive the pushing plate 47 to rise, the support rod 471 can prevent the pushing plate 47 from rotating and deflecting, ensuring that the pushing plate 47 is in a straight up and down state.

[0040] As an implementation manner of the present invention, referring to Figure 7 and Figure 8 and Figure 2, the lifting assembly 5 includes two sets of slide rails 51 fixedly connected to the inner side of the telescopic plate frame 2, a toothed plate 52 slidably connected to the slide rails 51, an elastic member II 53 installed at the bottom of the slide rails 51 (the bottom of the elastic member II 53 is fixedly connected to the slide rails 51 and the elastic member II 53 is not connected to the toothed plate 52), a connection block 54 fixedly connected to the toothed plate 52, a lifting frame 55 fixedly connected between the connection blocks 54, and an elastic member III 56 installed between the connection block 54 and the lifting frame 55; the two sets of slide rails 51 are respectively located at the two sets of gears I 34, and the toothed plate 52 meshes with the gear I 34; when the motor 31 drives the gear III 36, the gear I 34 and the gear II 35 to rotate, the gear I 34 will drive the toothed plate 52 to rise and then drive the lifting frame 55 to rise, so that the cable 12 rises to generate a bend. When the gear I 34 rotates to abut against the teeth at the bottom of the toothed plate 52, the toothed plate 52 will no longer be able to rise (this is when the toothed plate 52 rises to the highest point). At this time, the gear I 34 will continue to rotate until it drives the clamping block 42 to clamp the cable 12. And under the action of the elastic member IV 63, when the cable 12 is clamped and is subjected to a large pulling force that causes it to slide relative to the clamping block, the bent part will be straightened, thereby driving the lifting frame 55 to move downward with the toothed plate 52 against the elastic force of the elastic member IV 63, which can prevent the cable 12 from disconnecting the welding point at the connection head when subjected to a large instantaneous pulling force.

[0041] As an embodiment of the present invention, referring to Figure 1 and Figure 2 and Figure 8 , a receiving groove 13 that fits the outer shapes of the lifting frame 55 and the slide rails 51 is further opened on the chassis 1. When the entire telescopic plate frame 2 fits with the chassis 1, the lifting frame 55 and the slide rails 51 can enter the receiving groove 13, so that the telescopic plate frame 2 completely fits with the chassis 1, which can reduce the occupied area.

[0042] As an embodiment of the present invention, referring to Figure 9 , the limiting assembly 6 includes a housing sleeve 61 fixedly connected to the outside of the chassis 1, a limiting rod 62 telescopically connected to the housing sleeve 61, an elastic member IV 63 sleeved outside the limiting rod 62, and a limiting hole 64 opened on the rod body part of the telescopic plate frame 2. When the telescopic plate frame 2 is fully extended, the limiting rod 62 will be pushed by the elastic member IV 63 to be inserted into the limiting hole 64, thereby limiting the position of the telescopic plate frame 2 and preventing the telescopic plate frame 2 from moving after the clamping assembly 4 clamps the cable 12.

[0043] Working principle: Referring to Figure 1 and Figure 9, in the initial state, the telescopic plate frame 2 is in a fitting state with the chassis 1. When plugging in the cable 12, the cable 12 can be passed through the through-hole 21 and plugged into the socket 11. Then, the telescopic plate frame 2 is pulled open. After the telescopic plate frame 2 is completely pulled open, the limiting rod 62 will be inserted into the limiting hole 64 under the thrust of the elastic member four 63, thereby limiting the position of the telescopic plate frame 2. At this time, the telescopic plate frame 2 will lift the cable 12 that naturally hangs down along the side wall of the chassis 1, leaving a gap between the cables 12, facilitating ventilation and heat dissipation, and preventing the cable 12 that naturally hangs down from blocking the outside of the chassis 1 and causing the temperature of the device to rise.

[0044] Refer to Figures 3 to 6 , when the telescopic plate frame 2 is completely pulled open, the motor 31 can be started. The output shaft of the motor 31 will drive the third gear 36 to rotate. The third gear 36 will drive the second gear 35 and the first gear 34 to rotate in the same direction, thereby driving the two rotating rods 32 to rotate in the same direction. Since the spiral threads 33 at the adjacent two sets of closing rods 41 have opposite thread directions, when the two rotating rods 32 rotate, they will drive the closing rods 41 on both sides of each through-hole 21 to approach each other, thereby driving the two clamping blocks 42 on both sides of the through-hole 21 to approach each other. At the same time, the inner angles of the first articulated rod 44 and the second articulated rod 45 will gradually become smaller and approach each other, thereby driving the upper and lower two sets of push plates 47 to approach each other (since the bottom of the push plate 47 is fixedly connected with a support rod 471 that is slidably connected to the vertical groove 472, it can ensure that the push plate 47 is in a straight up and down state). Finally, the cable 12 is clamped between the clamping block 42 and the push plate 47. At the same time, when the closing rods 41 approach each other, they will also drive the contraction plate 48 to gradually tighten the push plate 47 against the elastic force of the first elastic member 49. After the push plate 47 and the clamping block 42 completely clamp the cable 12, the contraction plate 48 will also be completely retracted into the push plate 47 (this process can ensure that the contraction plate 48 is always in contact with the closing rod 41 to prevent the cable 12 from being misaligned between the closing rod 41 and the push plate 47), and under the action of the blocking rod 43, it can prevent the cable 12 from being misaligned and stuck in the gap between the push plate 47 and the clamping block 42.

[0045] Refer to Figure 7 and Figure 8 as well as Figure 2When the motor 31 drives the clamping assembly 4 to clamp the cable 12, the gear 34 will drive the tooth plate 52 to rise and then drive the lifting frame 55 to rise, thereby driving the cable 12 to rise and bend. When the gear 34 rotates to abut against the bottom teeth of the tooth plate 52, the tooth plate 52 will not be able to continue to rise (at this time, the tooth plate 52 rises to the highest point). At this time, the gear 34 will continue to rotate until it drives the clamping block 42 to clamp the cable 12. Under the action of the elastic member 4 63, when the cable 12 is clamped and subjected to excessive drag force, causing it to slide with the clamping block, the bent part will be straightened, thereby driving the lifting frame 55 to overcome the elastic force of the elastic member 4 63 and move downward with the tooth plate 52, thereby preventing the cable 12 from directly generating tension with the terminal head when subjected to a large instantaneous drag force, causing the cable 12 and the welding point at the terminal head to be disconnected.

[0046] Even though we have provided specific embodiments of the present invention, it should be clear to those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without violating the fundamental concept and purpose of the present invention. The scope of the present invention is not fixed, but is ultimately determined by the claims contained in the patent document and the equivalent technical solutions. In short, the scope of the present invention is defined by the attached claims and their equivalents.
