When the locking relationship between the front and rear latch hook plates 51, 52 and the latch hook seat 3 is released, the expansion chamber 8 is extended outward in a direction away from the fixed chamber 7. Since the related devices for extending the expansion chamber 8 out of the fixed chamber 7 and returning to the fixed chamber 7 belong to the prior art, for example, refer to patent documents such as CN103754150B and CN106428252B mentioned in the background section above by the applicant, and thus, the description thereof will not be repeated.
When the capacity expansion carriage 8 returns to the fixed carriage 7 to enable the vehicle to be in a running state, the capacity expansion carriage 8 and the fixed carriage 7 are locked by the invention, specifically: under the operation of the acting cylinder 61, the acting cylinder column 611 is driven to displace in the cylinder body direction, the acting cylinder column 611 drives the acting cylinder column connector 62 and the acting cylinder column connector 62 drives the latch hook plate acting pin 63 to slide rightwards, the compression on the front latch hook plate pressing legs 511 and the rear latch hook plate pressing legs 521 is relieved, at the moment, the right ends of the front latch hook plate 51 and the rear latch hook plate 52 fall under the action of the restoring force of the front latch hook plate tension springs 54 and the rear latch hook plate tension springs 55 and the action of the gravity center of the left weight and the right weight of the front latch hook plate 51 and the rear latch hook plate tension springs 52, at the moment, the front latch hook plate locking groove 512 and the rear latch hook plate locking groove 522 are hooked on the latch hook seat 3, and even under the conditions such as jolt, emergency brake and turning in the running process of a vehicle, the dilatation carriage 8 cannot be thrown out of the fixed carriage 7, and the technical effects recorded in the technical effect column of the applicant can be embodied faithfully. In addition, since the principle of locking and unlocking of one expansion tank 8 located on the right side of the fixed tank 7 illustrated in fig. 3 is the same as that described above, only the direction is opposite, and thus the applicant also does not repeat the description. Furthermore, the present invention is equally applicable to vehicle models similar to the CN10642825B structure.
In summary, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the task of the invention, and faithfully honors the technical effects carried by the applicant in the technical effect column above.
