Description

Technical Field

[0001] The utility model relates to the technical field of cover body installation, in particular to an installation structure of a cover body and a launch vehicle. Background Art

[0002] In the existing electric opening forms of the top of the cabin, there are sliding covers and flip covers; among them, the flip cover mostly adopts the electric push rod method, and the multi-link opening form is less used. The main reasons are that the multi-link opening structure is complex, the cost is too high, and the installation requirements are high. Since there are equipment with a large turning radius and need to rotate during operation in the cabin, such as when a laser device is in use, the angles of the sliding cover and the electric push rod flip cover methods will seriously affect the use of the equipment and cannot meet the use requirements of the laser device's pitch tracking range: -5° to +185°. Therefore, an opening method is needed in which the opening of the ship's hull top cover does not affect the normal use of the equipment. Content of the Utility Model

Specific embodiments

[0023] In order to make the purpose, technical solutions and beneficial effects of the present utility model clearer, the technical solutions in the present utility model will be further described below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] See Figures 1 to 2 , an installation structure of a cover body 2 is proposed in the embodiment of the present utility model, including:

[0025] A ship body 1, provided with a working opening 101;

[0026] A cover body assembly, including two cover bodies 2 arranged oppositely, the two cover bodies 2 are movably arranged on the ship body 1 and are used to open or close the working opening 101;

[0027] A driving assembly, including a plurality of first driving bodies and a plurality of second driving bodies arranged in one-to-one correspondence. One end of each first driving body and one end of each second driving body in each group are both hinged to the cover body 2, and the other ends of both form rotation points on the surface of the ship body 1. The first driving body and the second driving body are connected by a crank 5, so that under the action of an external force, the first driving body and the second driving body rotate synchronously forward and backward around their respective rotation points, and drive the cover body 2 to slide into or out of the working opening 101 relatively.

[0028] In this embodiment, a working opening 101 is provided on the ship hull 1 for the use of laser equipment. Two cover bodies 2 are provided on the ship hull 1 in a relatively arranged manner. The two cover bodies 2 are movably arranged on the ship hull 1 to open or close the working opening 101 for protecting the laser equipment. On the other hand, the two cover bodies 2 are respectively driven by a plurality of first driving bodies and a plurality of second driving bodies arranged in one-to-one correspondence. One end of the first driving body and the second driving body is hinged to the cover body 2, and the other end is hinged to the ship hull 1. The first driving body and the second driving body are connected by a crank 5. When the first driving body rotates forward and backward under an external force, the second driving body is linked by the crank 5 to rotate forward and backward synchronously to ensure the stability and synchronism of the movement of the cover body 2. Furthermore, the way that the first driving body and the second driving body drive the corresponding cover body 2 to open the cover is an opposed-opening type. Compared with the traditional single-opening sliding cover and flip cover opening methods, the height of the two cover bodies 2 in the same range after opening is lower than that of the single-opening flip cover method, and the stroke is shorter, meeting the use requirements of the laser equipment for the pitch tracking range of -5° to +185° during use.

[0029] The first driving body and the second driving body are respectively a first driving rod 3 and a second driving rod 4, and the first driving rod 3 and the second driving rod 4 are arranged in parallel.

[0030] In this embodiment, one end of the first driving rod 3 is hinged to the cover body 2, and the other end has a fixed rotating hinge on the ship hull 1. The first driving rod 3 can rotate on its axis. Similarly, one end of the second driving rod 4 is hinged to the cover body 2, and the other end is rotatably hinged to the ship hull 1. The second driving rod 4 is arranged in parallel with the first driving rod 3, so that the two are in the same direction in space. Such a setting helps to ensure the consistency of the two cover bodies 2 during the movement process, thereby ensuring the smoothness and symmetry of the movement of the cover body 2. When driven by an external power source (such as a motor), the first driving rod 3 and the second driving rod 4 will rotate forward and backward synchronously around their respective hinge points, and then drive the two cover bodies 2 to slide along a predetermined trajectory to open or close the working opening 101. Under the same movement range, the opening height is lower and more stable.

[0031] The cover body 2 is provided with a plurality of first installation points 6, and every two of the first installation points 6 are in a group for being respectively hinged to the first driving rod 3 and the second driving rod 4.

[0032] In the present embodiment, every two mounting points constitute a group, in which the first mounting point 6 of one group is used to hinge the first driving rod 3, and the other first mounting point 6 is used to hinge the second driving rod 4, which can ensure the synchronization of the two cover bodies 2 when sliding, and avoid the deflection or asymmetry problems that may be caused by single-point drive. At the same time, the cover body 2 is made in a frameless manner. Compared with other cover bodies 2, the cover body 2 does not serve as a force transmission device, which greatly improves the internal space. The cover body 2 is made in a frameless manner, has a lower weight, and has a smaller power requirement. The whole mechanism is more cost-effective and energy-efficient.

[0033] The hull 1 is provided with a plurality of second mounting points 7, and the second mounting points 7 are grouped in pairs, and are used to be respectively hinged to the first driving rod 3 and the second driving rod 4, and are configured to form corresponding rotation points.

[0034] In this embodiment, every two second mounting points 7 form a group, and one second mounting point 7 in each group is used to hinge the first driving rod 3, and the other second mounting point 7 is used to hinge the second driving rod 4, which ensures the coordination of the first driving rod 3 and the second driving rod 4 during movement. The second mounting point 7 is also the rotation point of the driving rod. When the driving rod is subjected to external force (such as power from a motor), the first driving rod 3 and the second driving rod 4 rotate around these points, and the cover body 2 is linked to slide, so that the rotational movement of the first driving rod 3 and the second driving rod 4 is converted into the sliding of the cover body 2. The two first mounting points 6 and the two second mounting points 7 respectively connect the first driving rod 3 and the second driving rod 4 to the cover body 2 and the hull 1, and are constructed into a parallelogram driving structure to provide the cover body 2 with stable movement.

[0035] A third mounting point 8 is provided at the middle of the first driving rod 3 and the middle of the second driving rod 4 for being respectively hinged to the two ends of the crank 5 .

[0036] In this embodiment, the third mounting point 8 is arranged in the middle of the first driving rod 3 and the second driving rod 4, and is used to connect with the crank 5, which can ensure that the driving force of the first driving rod 3 is evenly transmitted from the crank 5 to the driving rod. By connecting the crank 5 at the center position of the first driving rod 3 and the second driving rod 4, the entire structure can be more compact and space-saving, and the coordinated movement of the two driving rods is ensured, thereby ensuring the stability of the cover body 2 when sliding.

[0037] A main driving member is disposed at the rotation point of the first driving rod 3 , and a slave driving member is disposed at the rotation point of the second driving rod 4 . The slave driving member operates synchronously with the main driving member.

[0038] In this embodiment, through the setting of the master and slave driving members, the synchronous movement of the first driving rod 3 and the second driving rod 4 during driving can be ensured, enhancing the stability of the cover body 2 during sliding. Further, the master driving member and the slave driving member are respectively a master driving gear 9 and a slave driving gear 10, both the master driving gear 9 and the slave driving gear 10 are rotatably arranged on the ship body 1, and are connected by a synchronous chain 11 therebetween; in order to link the first driving rod 3 and the second driving rod 4 on the opposite end faces of the cover body 2, a master driving gear 9 and a slave driving gear 10 are respectively arranged on the first driving rod 3 and the second driving rod 4 at the front end of the cover body 2, and the two are connected by a synchronous chain 11. A connecting rod 15 is arranged on the first driving rod 3 at the rear end of the cover body 2 for connecting with the first driving rod 3 at the front end of the cover body 2, so that when the first driving rod 3 at the front end of the cover body 2 rotates forward and backward, the first driving rod 3 at the rear end of the cover body 2 is linked to rotate forward and backward synchronously.

[0039] The ship body 1 is provided with a first telescopic rod 12, and the cover body 2 is provided with a first limiting through hole 13. The first telescopic rod 12 can selectively extend into or out of the first limiting through hole 13 to limit or cancel the limitation of the movement of the cover body 2 when the cover body 2 opens the working port 101.

[0040] The ship body 1 is provided with a second telescopic rod 14, and the cover body 2 is provided with a second limiting through hole. The second telescopic rod 14 can selectively extend into or out of the second limiting through hole to limit or cancel the limitation of the movement of the cover body 2 when the cover body 2 closes the working port 101.

[0041] In this embodiment, a first telescopic rod 12 is arranged on the ship body 1, and a first limiting through hole 13 is arranged on the cover body 2. When the cover body 2 opens the working port 101, the first telescopic rod 12 extends out to enable the two cover bodies 2 to slide relative to each other. At the same time, a second telescopic rod 14 is arranged on the ship body 1, and a second limiting through hole is arranged on the cover body 2. When the cover body 2 slides to the maximum sliding distance, the second telescopic rod 14 extends into the second limiting through hole to limit the free movement of the cover body 2 and prevent the shaking of the cover body 2 from affecting the use of the laser device; it can be understood that in this embodiment, the first limiting through hole 13 and the second limiting through hole can be the same. Under reasonable design, when the cover body 2 opens the working port 101, the first telescopic rod 12 extends out of the first limiting through hole 13 to enable the cover body 2 to slide. When the cover body 2 slides to the maximum use distance, the first limiting through hole 13 moves to align with the second telescopic rod 14, and the second telescopic rod 14 extends into the first limiting through hole 13 to position the cover body 2.

[0042] The opposite end faces of the two cover bodies 2 are respectively provided with a matching positioning groove 17 and a positioning protrusion 16, so that when the cover body 2 closes the working port 101, the positioning protrusion 16 extends into the positioning groove 17.

[0043] In this embodiment, positioning grooves 17 and positioning protrusions 16 are respectively arranged on the opposite end faces of the two cover bodies 2, which can ensure that the two cover bodies 2 can be accurately docked when closed. The positioning protrusions 16 are inserted into the positioning grooves 17, which not only enhances the sealing performance between the cover bodies 2, but also improves the overall stability of the cover bodies 2 in the closed state.

[0044] This embodiment also proposes a launch vehicle, which includes the installation structure of the cover body 2 described above. The specific structure of this launch vehicle refers to the above embodiment. Since this launch vehicle adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be elaborated here one by one.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
