Description

Technical Field

[0001] The present invention relates to the technical field of mobile cabins, in particular to an expandable side panel mechanism and a mobile cabin for a mobile cabin. Background Art

[0002] Mobile cabins are widely used in the medical field due to their flexibility and sealing. In order to ensure that the mobile cabin has a large internal space during use, it is usually necessary to horizontally expand the volume of the mobile cabin.

[0003] For example, a surgical mobile cabin with an expandable function disclosed in Patent No. 202110906600.4 includes: a fixed cabin body, an expansion mechanism is arranged on the side of the fixed cabin body, the expansion mechanism includes an airbag side expansion surface and an air pump, the airbag side expansion surface is fixedly installed on both sides of the fixed cabin body, a moving panel is fixedly installed on the side of the airbag side expansion surface away from the fixed cabin body, a moving wheel is fixedly installed at the bottom of the moving panel, and the air pump is fixedly installed on the top of the inner cavity of the fixed cabin body.

[0004] In the above patent, airbags are used as the bottom plate and top plate of the expanded chamber. The structural strength is low, high-load equipment cannot be configured on the inner side, and it is easily deformed under pressure on the outer side. At the same time, due to the certain elasticity of the airbag, the stability is poor, and it is extremely easy to shake when personnel operate inside the expanded area. Summary of the Invention

[0005] To solve the deficiencies of the above-mentioned prior art, the present invention provides an expandable side panel mechanism and a mobile cabin for a mobile cabin, effectively improving the structural strength and stability of the horizontal expansion part of the mobile cabin.

[0006] The technical solution of the present invention is: an expandable side panel mechanism for a mobile cabin, including an upper flip plate, a lower flip plate, a flexible baffle, and a lateral support frame. The upper flip plate is hinged to the outside of the top plate of the mobile cabin, the lower flip plate is hinged to the outside of the bottom plate of the mobile cabin, a first flipping mechanism for driving the upper flip plate to rotate away from / towards the mobile cabin is installed on the upper flip plate, a second flipping mechanism for driving the lower flip plate to rotate away from / towards the mobile cabin is installed on the lower flip plate, the flexible baffle surrounds between the mobile cabin and the unfolded upper flip plate and lower flip plate to form a sealed chamber, and the lateral support frame is detachably installed between the unfolded upper flip plate and lower flip plate, and the outside of the lateral support frame abuts against the inner side of the flexible baffle. After the upper flip plate and the lower flip plate are unfolded, a horizontal expansion part is formed. Compared with the airbag in the prior art, the longitudinal structural strength is ensured. A lateral support frame is added between the upper flip plate and the lower flip plate to ensure the structural strength of the lateral side, and at the same time, the plate-shaped support surface ensures the stability of the horizontal expansion part.

[0007] A plurality of support legs are arranged on the side of the lower flip plate away from the mobile cabin. The support legs are spaced apart along the length direction of the mobile cabin and are detachably installed on the lower flip plate. The setting of the support legs can further improve the stability at the lower flip plate.

[0008] The first flipping mechanism is two electric push rods distributed on both sides of the upper flipping plate. One end of the electric push rod is hinged to the inner side of the shelter, and the other end of the electric push rod is hinged to the bottom of the upper flipping plate.

[0009] The second flipping mechanism includes a manual winch, a fixed pulley, and a steering pulley group. The manual winch is embedded in the front side wall of the shelter. The fixed pulley is located above the manual winch and fixed to the front side wall of the shelter. The steering pulley group consists of two, which are respectively fixed on both sides of the end of the lower flipping plate far from the shelter. The pulling rope of the manual winch passes through the fixed pulley and the steering pulley group in sequence and is fixedly connected to the rear side wall of the shelter. The setting of the fixed pulley and the steering pulley group realizes the driving of the lower flipping plate by a single manual winch, making the operation more convenient.

[0010] The steering pulley group includes a pulley seat, a horizontal pulley, and a vertical pulley. The pulley seat is fixed on the lower flipping plate. The horizontal pulley and the vertical pulley are distributed in sequence along the direction away from the shelter and rotatably installed on the pulley seat. A wire passing channel for the pulling rope to pass through is formed on the lower flipping plate between the pulley seat and the two pulley seats.

[0011] The lateral support frame includes a plurality of vertical telescopic rods spaced along the length direction of the shelter. One end of the vertical telescopic rod is hinged to the outer bottom of the upper flipping plate. When the vertical telescopic rod rotates to the first position away from the shelter, the fixed end of the vertical telescopic rod is fixed to the outer surface of the lower flipping plate through a pin. When the vertical telescopic rod rotates to the second position close to the shelter, the vertical support rod is clamped on the hoop at the bottom of the upper flipping plate. The rotational conversion between the first position and the second position of the vertical telescopic rod ensures its lateral support effect on the flexible baffle while effectively accommodating it.

[0012] The lateral support frame further includes a plurality of transverse connecting rods and lateral connecting rods. The transverse connecting rods are spaced along the height direction of the shelter and the transverse connecting rods are fixedly connected to each vertical telescopic rod. The lateral connecting rods are located at the front and rear side walls of the shelter. Both ends of the lateral connecting rods are connected to the side wall of the shelter and the outermost vertical telescopic rod respectively through pins. The transverse support rods and the lateral connecting rods can further improve the lateral structural strength of the lateral expansion part.

[0013] The flexible baffle is a tarpaulin cover. The tarpaulin cover covers the upper flipping plate. The outer side of the tarpaulin cover is hermetically connected to the outer edges of the top plate and the front and rear side walls of the shelter. The bottom of the tarpaulin cover is hermetically connected to the outer edge of the lower flipping plate.

[0014] The size of the lower flap is adapted to the size of the side opening of the mobile cabin. The upper flap and the lower flap are successively flipped along the direction close to the mobile cabin. The inner side of the lower flap is opposite to the outer side of the upper flap, and the outer side of the lower flap forms the side plate of the mobile cabin. A container locking rod for locking the lower flap with the outer side of the top plate of the mobile cabin is installed on the lower flap.

[0015] A mobile cabin includes the expandable mobile cabin side plate mechanism. There are openings on both sides of the mobile cabin. There are two expandable mobile cabin side plate mechanisms, which are symmetrically installed at the openings on both sides of the mobile cabin respectively, and the compartments of the expandable mobile cabin side plate mechanisms are communicated with the openings of the mobile cabin.

[0016] The beneficial effects of the present invention are as follows: the upper flap and the lower flap form a lateral expansion part after being unfolded, which ensures the longitudinal structural strength of the lateral expansion part. A lateral support frame is added between the upper flap and the lower flap to ensure the lateral side structural strength of the lateral expansion part. At the same time, the plate-shaped support surface ensures the stability of the lateral expansion part. Description of the Drawings

Other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figure 1 , Figure 3 and Figure 4 shown, the present invention provides an extended side panel mechanism for a shelter, including an upper flip plate 2, a lower flip plate 3, a flexible baffle, and a lateral support frame. The upper flip plate 2 is hinged to the outer side of the top plate 101 of the shelter 1, and the lower flip plate 3 is hinged to the outer side of the bottom plate 102 of the shelter 1. A first flipping mechanism for driving the upper flip plate 2 to rotate away from / towards the shelter 1 is installed on the upper flip plate 2, and a second flipping mechanism for driving the lower flip plate 3 to rotate away from / towards the shelter 1 is installed on the lower flip plate 3. The flexible baffle surrounds the shelter 1 and the unfolded upper flip plate 2 and lower flip plate 3 to form an enclosed cabin. The lateral support frame is detachably installed between the unfolded upper flip plate 2 and lower flip plate 3, and the outer side of the lateral support frame abuts against the inner side of the flexible baffle. Specifically, the flexible baffle is a tarpaulin cover 11. The tarpaulin cover 11 covers the upper flip plate 2. After the upper flip plate 2 is unfolded, it can support the tarpaulin cover 11 upward. The outer side of the tarpaulin cover 11 is sealed and connected to the outer edges of the top plate 101 and the front and rear side walls of the shelter 1, and the bottom of the tarpaulin cover 11 is sealed and connected to the outer edge of the lower flip plate 3. In other embodiments, the flexible baffle can be a flexible foldable fabric made of waterproof materials such as TPU or nylon. The lateral support frame includes a plurality of vertical telescopic rods 4 spaced apart along the length direction of the shelter 1. One end of the vertical telescopic rod 4 is hinged to the outer bottom of the upper flip plate 2. When the vertical telescopic rod 4 rotates to the first position away from the shelter 1, the fixed end of the vertical telescopic rod 4 is fixed to the outer surface of the lower flip plate 3 through a pin. When the vertical telescopic rod 4 rotates to the second position close to the shelter 1, the vertical support rod is clamped on the hoop 201 at the bottom of the upper flip plate 2.

[0020] A transverse expansion part is formed after the upper flip plate 2 and the lower flip plate 3 are unfolded. Compared with the airbag in the prior art, the longitudinal structural strength is ensured. When the vertical telescopic rod 4 rotates to the first position, a lateral support frame between the upper flip plate 2 and the lower flip plate 3 is formed, thus ensuring the structural strength of the transverse side. At the same time, the plate-shaped support surfaces of the upper flip plate 2 and the lower flip plate 3 ensure the stability of the transverse expansion part.

[0021] To further improve the stability of the side panel structure, a plurality of support legs 12 are provided on the side of the lower flip plate 3 away from the shelter 1. The support legs 12 are spaced apart along the length direction of the shelter 1 and are detachably installed on the lower flip plate 3. Specifically, a plurality of fixed seats are fixed along the length direction on the side of the lower flip plate 3 away from the shelter 1, and the vertical ends of the support legs 12 are fixed to the fixed seats through bolts.

[0022] Further, the first flipping mechanism comprises two electric push rods 7 distributed on both sides of the upper flipping plate 2. One end of each electric push rod 7 is hinged to the inner side of the shelter 1, and the other end is hinged to the bottom of the upper flipping plate 2.

[0023] Further, as Figure 5 and Figure 7 shown, the second flipping mechanism comprises a manual winch 8, a fixed pulley 9 and a steering pulley group 10. The manual winch 8 is embedded in the front side wall of the shelter 1. The fixed pulley 9 is located above the manual winch 8 and fixed to the front side wall of the shelter 1. The steering pulley group 10 has two members, which are respectively fixed to both sides of the end of the lower flipping plate 3 far from the shelter 1. The pulling rope 801 of the manual winch 8 passes through the fixed pulley 9 and the steering pulley group 10 in sequence and is fixedly connected to the rear side wall of the shelter 1. Among them, the steering pulley group 10 comprises a pulley seat 1001, a horizontal pulley 1002 and a vertical pulley 1003. The pulley seat 1001 is fixed to the lower flipping plate 3. The horizontal pulley 1002 and the vertical pulley 1003 are distributed in sequence along the direction away from the shelter 1 and rotatably installed on the pulley seat 1001. A wire guiding channel 301 for the pulling rope 801 to pass through is formed on the lower flipping plate 3 between the pulley seat 1001 and the two pulley seats 1001. The arrangement of the fixed pulley 9 and the steering pulley group 10 realizes the driving of the lower flipping plate 3 by a single manual winch 8, and the operation is more convenient. The manual winch 8 is a prior art, and its structure and rotation principle will not be elaborated.

[0024] To further improve the structural strength of the lateral expansion part laterally, the lateral support frame further comprises a plurality of transverse connecting rods 5 and lateral connecting rods 6. The transverse connecting rods 5 are distributed at intervals along the height direction of the shelter 1, and the transverse connecting rods 5 are fixedly connected to the respective vertical telescopic rods 4. The lateral connecting rods 6 are located at the front and rear side walls of the shelter 1. Both ends of the lateral connecting rods 6 are connected to the side wall of the shelter 1 and the outermost vertical telescopic rod 4 respectively through pins.

[0025] As Figure 2 and Figure 6 shown, the size of the lower flipping plate 3 is adapted to the size of the lateral opening of the shelter 1. The upper flipping plate 2 and the lower flipping plate 3 flip along the direction close to the shelter 1. The upper flipping plate 2 is located inside the lower flipping plate 3, and the inner side of the lower flipping plate 3 is opposite to the outer side of the upper flipping plate 2. The outer side of the lower flipping plate 3 forms the side plate of the shelter 1. To ensure the airtightness of the entire airtight cabin, a rubber plate 14 is sealed inside the hinge joint of the lower flipping plate 3 and the bottom plate 102. A container lock rod 13 for locking the outer side of the lower flipping plate 3 and the top plate 101 of the shelter 1 is installed on the lower flipping plate 3. The container lock rod 13 is a prior art, and its internal structure and principle will not be elaborated.

[0026] A mobile cabin includes the above-mentioned expandable side panel mechanism of the mobile cabin. There are openings on both sides of the mobile cabin 1. There are two expandable side panel mechanisms of the mobile cabin, which are symmetrically installed at the openings on both sides of the mobile cabin 1 respectively, and the cabins of the expandable side panel mechanisms are connected to the openings of the mobile cabin 1, so that the whole mobile cabin 1 has the largest lateral expansion space. A control cabinet is also arranged inside the mobile cabin 1, and the control cabinet is electrically connected to the electric push rod 7 for controlling the operation of the electric push rod 7.

[0027] When implementing this technical solution, connect the power supply of the whole mobile cabin 1, open the container lock rod 13 on the lower flip plates 3 on both sides of the mobile cabin 1, and reverse-rotate the manual winch 8 to operate the unfolding of the lower flip plates 3. Wait until the lower flip plates 3 are unfolded to be parallel to the bottom plate 102 of the mobile cabin 1, lock the manual winch 8, and fix the support legs 12 outside the lower flip plates 3 to realize the positioning after the lower flip plates 3 are unfolded. Control the four electric push rods 7 to run synchronously through the control cabinet. During the unfolding of the upper flip plates 2, the tarpaulin cover 11 above the upper flip plates 2 is lifted until it is parallel to the top plate 101 and enters the interior of the mobile cabin 1. Remove the vertical telescopic rod 4 at the bottom of the upper flip plate 2 from the hoop 201 and turn it to the first position of the vertical telescopic rod 4. The lower end of the vertical telescopic rod 4 extends and is fixed on the lower flip plate 3 through a pin. At the same time, take out the lateral connecting rod 6. The two ends of the lateral connecting rod 6 are respectively connected to the side wall of the mobile cabin 1 and the outermost vertical telescopic rod 4 through pins. At this time, the outer sides of the vertical telescopic rod 4, the lateral connecting rod 6 and the horizontal connecting rod 5 on the vertical support rod are in contact with the tarpaulin cover 11, and a lateral support frame for the tarpaulin cover 11 will be formed. The structural strength and stability of the lateral expansion part of the whole mobile cabin 1 are effectively improved compared with the prior art. When storing, operate in reverse, remove the pin positions of the lateral connecting rod 6 and the vertical telescopic rod 4 in turn, and turn the vertical telescopic rod 4 to the second position and clamp it under the upper flip plate 2 through the hoop 201. Fold the upper flip plates 2 and the lower flip plates 3 in turn, and the tarpaulin cover 11 is folded between the lower flip plates 3 and the upper flip plates 2.
