[0002] Data storage cards are a common type of airborne electronic device, allowing for quick installation and removal from the aircraft via card holders and racks. Compared to general data storage devices, airborne data storage cards need to be highly vibration-resistant, have a long service life, and be easy to install and remove. Traditional data storage devices generally have weak vibration resistance and are prone to wear and tear and card holder jamming after prolonged use. Summary of the Invention

[0003] The purpose of this invention is to provide a novel airborne single-sided locking cartridge data storage card structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a novel airborne single-sided locking spring-loaded data storage card structure, comprising a card holder and a card box that slides into the card holder. A locking mechanism is provided on one side of the card holder to limit the side of the card box. A socket is provided near the center of the rear of the card holder to mate with the end of the card box, and a spring-loaded mechanism is provided at the bottom of the socket. A left guide rail and a right guide rail are symmetrically arranged on the left and right sides of the inner cavity of the card holder, respectively. Through-type sliding grooves with opposite openings are provided on the opposing surfaces of the left and right guide rails. An opening for inserting the card box is provided at the front end of the card holder.

[0005] Furthermore, the card box includes an upper card box, a lower card box, and a guide rail plate located between the upper card box and the lower card box. The front and rear ends of the guide rail plate are flush with the front and rear ends of the upper card box and the lower card box. The left and right sides of the guide rail plate protrude from the upper card box and the lower card box and slide into the grooves of the left and right guide rails. A limiting groove is reserved in the middle of the left and right sides of the guide rail plate.

[0006] Furthermore, the guide rail plate is made of wear-resistant material, and the two sides of the insertion end of the guide rail plate are provided with guide bevels to facilitate insertion, and the middle of the insertion end is provided with a plug that mates with the socket.

[0007] Furthermore, the locking mechanism includes an upper locking cover and a lower locking cover fixedly installed in the side housing of the card holder, and a lock head slidably installed between the upper locking cover and the lower locking cover. Both ends of the lock head are equipped with top tubes, a button is fixedly installed on the front top tube, and a pressing spring is sleeved on the rear top tube. The button is slidably embedded on the front end face of the card holder, and the rear top tube slides through the fixing plate set in the side housing of the card holder, and the two ends of the pressing spring abut against the lock head and the fixing plate respectively.

[0008] Furthermore, the lock head has an oblique groove in the middle, and a reversing bearing is slidably embedded in the oblique groove. The lock head has a groove on the side and a lock tongue is slidably embedded therein. One end of the lock tongue is inserted into the lock head and fixed to the reversing bearing, and the other end extends out of the lock head and is equipped with a rolling bearing.

[0009] Furthermore, the spring-loaded mechanism includes a top block, a seat block, a spring-loaded spring, a guide pin, and a base plate. The seat block is embedded in the center of the bottom of the socket. The top block is slidably disposed in the seat block, with one end extending out of the seat block and pointing towards the front opening of the card holder, and the other end slidably sleeved on the guide pin. The base plate is vertically fixed to the rear of the card holder. The end of the guide pin away from the top block is fixedly connected to the base plate. The spring-loaded spring is sleeved on the guide pin between the top block and the base plate.

[0010] Furthermore, screws are fixed to the left and right side walls of the seat block, and guide grooves are provided on the left and right side walls of the top block for the screws to slide into.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] This invention provides a novel airborne single-sided locking cartridge data storage card structure that integrates a press-type rolling bearing locking mechanism, a near-center spring-loaded mechanism, a through-type guide rail, a card holder, and a card box. It features good guidance, vibration resistance, wear resistance, anti-jamming, and simple and quick loading and unloading. The press-type rolling bearing locking mechanism on the inner side of the card holder and the near-center spring-loaded mechanism at the rear achieve locking and spring-loaded operation of the card box, enabling convenient loading and unloading of the card box and effectively enhancing the vibration resistance of the data storage card structure. Simultaneously, the bearing locking mechanism, in conjunction with the through-type guide rail, effectively enhances the guiding effect of card box insertion, reduces frictional resistance, and thus greatly improves the wear and jamming problems of the card box during long-term use.

[0021] Please see Figure 1-4 This invention provides a technical solution: a novel airborne single-sided locking spring-loaded data storage card structure, including a card holder 1 and a card box 2 that slides into the card holder 1. A locking mechanism 3 is provided on one side of the card holder 1 to limit the side of the card box 2. A socket 7 is provided near the center of the rear of the card holder 1 to cooperate with the end of the card box 2, and a spring-loaded mechanism 4 is provided at the bottom of the socket 7. A left guide rail 5 and a right guide rail 6 are symmetrically arranged on the left and right sides of the inner cavity of the card holder 1, and through-type sliding grooves with opposite openings are opened on the opposite surfaces of the left guide rail 5 and the right guide rail 6. An opening for the card box 2 to be inserted is reserved at the front end of the card holder 1.

[0022] Furthermore, the card box 2 includes an upper card box 24, a lower card box 23, and a guide rail plate 25 located between the upper card box 24 and the lower card box 23. The front and rear ends of the guide rail plate 25 are flush with the front and rear ends of the upper card box 24 and the lower card box 23. The left and right sides of the guide rail plate 25 protrude from the upper card box 24 and the lower card box 23 and slide into the grooves of the left guide rail 5 and the right guide rail 6. A limiting groove is reserved in the middle of the left and right sides of the guide rail plate 25.

[0023] Furthermore, the guide rail plate 25 is made of wear-resistant material, and the two sides of the insertion end of the guide rail plate 25 are provided with guide bevels to facilitate insertion, and the middle of the insertion end is provided with a plug 22 that mates with the socket 7.

[0024] Furthermore, the locking mechanism 3 includes an upper locking cover 9 and a lower locking cover 10 fixedly installed in the side housing of the card holder 1, and a lock head 14 slidably installed between the upper locking cover 9 and the lower locking cover 10. The lock head 14 has a top tube installed at both ends. A button 8 is fixedly installed on the front top tube, and a pressing spring 15 is sleeved on the rear top tube. The button 8 is slidably embedded on the front end face of the card holder 1, and the rear top tube slides through the fixing plate set in the side housing of the card holder 1. The two ends of the pressing spring 15 abut against the lock head 14 and the fixing plate, respectively.

[0025] Furthermore, the lock head 14 has an oblique groove in the middle, and a reversing bearing 13 is slidably embedded in the oblique groove. The lock head 14 has a groove on the side and a lock tongue 12 is slidably embedded therein. One end of the lock tongue 12 is inserted into the lock head 14 and fixedly connected to the reversing bearing 13, and the other end extends out of the lock head 14 and is equipped with a rolling bearing 11.

[0026] Furthermore, the spring-loaded mechanism 4 includes a top block 16, a seat block 18, a spring-loaded spring 19, a guide pin 20, and a base plate 21. The seat block 18 is embedded in the center of the bottom of the socket 7. The top block 16 is slidably disposed in the seat block 18, with one end extending out of the seat block 18 and pointing towards the front opening of the card holder 1, and the other end slidably sleeved on the guide pin 20. The base plate 21 is vertically fixed to the rear of the card holder 1. The end of the guide pin 20 away from the top block 16 is fixedly connected to the base plate 21. The spring-loaded spring 19 is sleeved on the guide pin 20 between the top block 16 and the base plate 21.

[0027] Furthermore, screws 17 are fixedly installed on the left and right side walls of the seat block 18, and guide grooves for the screws 17 to slide into are opened on the left and right side walls of the top block 16.

[0028] Working principle:

[0029] like Figure 1As shown, the card holder 2 is inserted through the front opening of the card holder 1. Then, the guide rails 25 of the card holder 2 enter the through-type sliding grooves of the wear-resistant left guide rail 5 and right guide rail 6. The left guide rail 5 and right guide rail 6 guide the card holder 2 from the entrance, effectively reducing the impact of the card holder 2. Before the card holder 2 slides into place, the locking tongue 12 in the locking mechanism 3 does not contact the guide rail 25 in the card holder 2. Instead, the rolling bearing 11 contacts the guide rail 25, which can effectively reduce frictional resistance and reduce wear. After the card holder 2 is inserted into the bottom of the card holder 1 and docked with the socket 7, the limiting groove in the middle of the guide rail 25 in the card holder 2 is locked with the locking tongue 12 in the locking mechanism 3. At the same time, with the action of the spring-loaded mechanism 4, the card holder 2 is secured in the card holder 1, which greatly improves the vibration resistance of the data storage card structure.

[0030] When removing the card holder 2, simply press button 8 to push the locking tongue 12 out of the groove of the guide plate 25, and the card holder 2 will be smoothly ejected from the card holder 1 under the action of the ejector mechanism 4. During the ejection process, the ejector mechanism 4, which is set near the center, can effectively reduce the eccentric torque on the card holder 2, thereby greatly reducing the probability that the card holder 2 will get stuck in the card holder 1.

[0031] like Figure 2 As shown, when button 8 is pressed, the front top tube pushes the lock head 14 to move longitudinally. The reversing bearing 13 in the locking mechanism 3 moves in the inclined groove of the lock head 14, converting the longitudinal movement of the lock head 14 into the lateral movement of the latch 12, thereby enabling the latch 12 to easily exit from the limiting groove in the middle of the guide plate 25. The pressing spring 15 sleeved on the rear top tube of the lock head 14 can make the button 8 rebound smoothly, ensuring that the latch 13 and the card box 2 are firmly locked. The rolling bearing 11 protrudes slightly from the latch 12, ensuring that the card box 2 contacts the guide plate 25 first during the insertion of the card holder 1, reducing the insertion resistance and reducing the wear of the card box 2. After the card box 2 is inserted into place, the latch 12 is locked into the limiting groove of the guide plate 25, ensuring the card box 2 is secure. The locking mechanism 3, while ensuring the ease of use of the data storage card structure and the locking function, greatly reduces wear and makes the insertion and removal process smoother.

[0032] like Figure 3 As shown, the ejector mechanism 4 is arranged near the center of the rear of the card holder 1. After the card holder 2 is inserted and aligned, the top block 16 presses against the end of the lower card holder 23 of the card holder 2. Together with the locking mechanism 3, it effectively ensures the tightness of the card holder 2 installation and improves the vibration resistance of the data storage card structure. At the same time, its near-center arrangement effectively eliminates the eccentric torque generated during the contact process with the card holder 2, so that the plug 22 of the card holder 2 can be smoothly connected with the socket 7, and the ejection process avoids jamming. The ejector spring 19 can be designed with a corresponding length according to the required ejector force, thereby controlling the ejection stroke of the card holder 2.

[0033] like Figure 4As shown, the guide plate 25 of the card box 2 is located between the upper card box 24 and the lower card box 23. It is flush with the front and back, protruding on both sides, and has a guide bevel at the front end for easy insertion. The middle part has a limiting groove that cooperates with the locking tongue 12 to realize the locking function. The guide plate 25 is made of wear-resistant material and directly contacts the locking mechanism 3 to avoid wear caused by direct contact with the upper card box 24 and the lower card box 23. At the same time, the guide plate 25, which protrudes through the front and back, cooperates with the sliding grooves of the through-type left guide rail 5 and right guide rail 6 to effectively assist in guidance, making the loading and unloading of the card box 2 more convenient.

[0034] This invention provides a novel airborne single-sided locking cartridge data storage card structure, which features good guidance, vibration resistance, wear resistance, anti-jamming, and simple and quick loading and unloading. It has been successfully applied in the data management equipment of a certain type of aircraft.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
