[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] See Figures 1-6 .

[0017] This utility model provides a train health management device, comprising: Electrical cabinet 1, located on the train, is equipped with several pull-out storage drawers 3; The storage cavity 2 is used to accommodate the storage drawer 3; correspondingly, the storage drawer 3 is equipped with a PHM host 4, a driver's cab monitoring host 5, a passenger cabin broadcast host 6, and a signal host 7. A connecting mechanism is located at the corresponding storage cavity 2 of the electrical cabinet 1. The connecting mechanism controls the speed at which the storage drawer 3 is pulled out and pushed forward in the electrical cabinet 1.

[0018] The support blocks 8 are arranged in pairs and symmetrically in the same storage cavity 2. The storage drawer 3 is slidably disposed on the two support blocks 8 on the same layer to support the storage drawer 3.

[0019] In one embodiment, the connecting mechanism includes a spur gear 9, and the support block 8 is provided with a working groove 10 near the outlet end of the storage cavity 2. The spur gear 9 is rotatably disposed in the working groove 10. The storage drawer 3 is provided with a rack 11 along the depth direction of the storage cavity 2. The rack 11 meshes with the spur gear 9. The spur gear 9 is provided with several protective parts to stop the movement of the storage drawer 3 when the speed at which the storage drawer 3 is pulled out and pushed exceeds the speed limit.

[0020] In one embodiment, the protective component includes a storage tube 12 and a spring 13. The storage tube 12 is located on the spur gear 9. A brake plug 14 is slidably connected inside the storage tube 12. A brake groove 15 is provided in the working groove 10. A reset block 16 is connected to the brake groove 15 through the spring 13 for contacting the brake plug 14. When the staff pulls or pushes the storage drawer 3, the rack 11 on the storage drawer 3 meshes with the sprocket 9, causing the sprocket 9 to rotate. The sprocket 9 then drives the protective parts on it to rotate synchronously. The protective parts do not affect the rotation of the sprocket 9. When the pulling or pushing force is too great, the rotation speed of the sprocket 9 will increase, and the centrifugal force on the protective parts will be too great. All the protective parts will be subjected to centrifugal force, but only the protective parts that slide to the brake groove 15 will be inserted into the brake groove 15 under the action of centrifugal force. The remaining protective parts will be blocked by the working groove 10 and the groove 18 on the storage drawer 3, so that the brake insert 14 remains inside the storage cylinder 12 and does not move.

[0021] One end of the brake insert 14 is inserted into the brake groove 15 under the action of centrifugal force, and the other end slides in the storage cylinder 12. The spring 13 is contracted by external force. The brake insert 14 is restricted by the brake groove 15 and cannot continue to rotate. The brake insert 14, the storage cylinder 12 and the spur gear 9 stop rotating synchronously.

[0022] At this point, the staff will feel that the storage drawer 3 is encountering resistance and stops sliding, which reminds the staff that the force applied is too great and needs to be adjusted. The staff should reduce the force. The addition of a foolproof function during the staff's long-term repetitive work prevents the cable from being pulled too hard when the storage drawer 3 is pulled out quickly, and prevents the cable interface of the main unit from becoming loose, thus maintaining the normal and stable operation of the equipment.

[0023] After the brake insert 14 is no longer subjected to centrifugal force, the spring 13's own elastic force drives the reset block 16 to reset along the brake groove 15. During the reset process, the brake insert 14 is pushed to disengage from the brake groove 15 and reset. The storage drawer 3 is provided with a groove 18, which is spliced ​​with the working groove 10 to form a circle. The brake insert 14 is fully inserted into the storage drawer 3 again to avoid affecting the rotation of the spherical gear 9.

[0024] Furthermore, the support block 8 is provided with a limiting groove 17, and the storage drawer 3 is symmetrically provided with limiting blocks. The limiting blocks are slidably disposed in the limiting groove 17 to prevent the storage drawer 3 from separating from the support block 8.

[0025] The PHM host 4 is used to collect data from the train's network system, gathered by sensors throughout the train. The PHM host 4 includes a circuit board with a data acquisition module circuit. This acquisition module circuit includes a conversion circuit that converts CAN bus and MVB protocols into TCP protocols. This protocol conversion is existing technology; it is included here to emphasize that it overcomes the limitations of traditional TCP protocols, achieving seamless network redundancy and rapid fault switching. When used in conjunction with the connection mechanism, it significantly improves the stability and efficiency of the PHM host 4 through both physical and communication improvements.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0027] It should be noted that if the utility model embodiment involves directional indicators such as up and down, the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the figure. If the specific posture changes, the directional indicators will also change accordingly.

[0028] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more.

[0029] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of the utility model.
