Description

Technical Field

[0002] Generally speaking, underwater vehicles (torpedoes, self-propelled acoustic decoys, unmanned submarines) are important combat forces in future underwater warfare. As the complexity and frequency of underwater missions continue to increase, underwater vehicles have higher and higher requirements for their own endurance and operating efficiency. In recent years, battery technology has continued to advance, especially in terms of energy density, charging and discharging efficiency, and safety, making power batteries gradually become the main driving method for underwater vehicles. However, the existing underwater vehicle battery pack filling process is complicated, and professional personnel are required to operate during the battery filling process. Repeated adjustments and calibrations during the filling process make it difficult to accurately align and fill, and the efficiency is low; on the other hand, different types of battery packs differ in shape, size, and interface, resulting in poor adaptability of the filling device. A single filling device can only meet the filling and use requirements of the same type of battery pack, which also increases the use and maintenance costs of battery pack filling.

[0129] More specifically, Figure 3 and Figure 7 As shown, the push-pull block 31 includes:

[0130] A push-pull block body, one end surface of which is provided with a plurality of push-pull block connection holes;

[0134] The chain connecting plates 311 are adapted to the outer teeth of the pinion gear of the driven gear set and the outer teeth of the rotating gear.

[0135] In the present invention, the working principle of the push-pull assembly 3 is: the operator turns the crank to drive the driving gear connected to it to rotate, and then the driving gear drives the large gear of the driven gear group meshing with it to rotate, so that the large gear of the driven gear group drives the small gear of the driven gear group fixedly connected to it to rotate, and then the small gear of the driven gear group drives the transmission chain to rotate around the rotating gear, and finally, the rotation of the transmission chain drives the push-pull block 31 to move forward or backward along the battery pack bracket 1.

[0136] In the present invention, the roller group 312 includes two vertical rollers vertically connected to the push-pull block body and two transverse rollers horizontally rotating inside the two vertical rollers. The roller group 312 is respectively contacted and connected with the inner wall of the adjustment device mounting plate 12 on the corresponding side; the non-connecting end of the push head connector 313 is made of rubber, and the push head connector 313 is used to push the battery pack 7 into the battery shell section 8 of the navigation body for use. The stud bolt connector 314 is used to simultaneously connect the push-pull block 31 and the battery pack 7 in the battery shell section 8 of the navigation body for use, so as to facilitate pulling the battery pack 7 in the battery shell section 8 of the navigation body onto the battery pack bracket 1.

[0137] Further, such as Figure 4 and 6 As shown, the traverse assembly 4 includes:

[0138] A transverse connecting frame 41, wherein lifting rod connecting holes are provided through the middle of both ends of the transverse connecting frame 41, and both ends of the transverse connecting frame 41 are also connected to the lower ends of the battery pack bracket 1 through transverse connecting seats;

[0139] A worm gear transmission mechanism 42, which is connected to the middle of the transverse connecting frame 41, and an upper portion of the worm gear transmission mechanism 42 is provided with a worm gear connector connected to the battery pack bracket 1, and rotating the rocker of the worm gear transmission mechanism can drive the worm gear connector to rotate back and forth laterally;

[0140] The mobile base 5 comprises:

[0141] Frame 51;

[0142] Front moving wheels 52, which are symmetrically arranged on both sides below the front end of the frame 51, and a front moving wheel brake mechanism 53 is arranged above the front moving wheels 52 to work together with them;

[0143] The rear moving wheels 54 are symmetrically arranged on both sides below the rear end of the frame 51, and each rear moving wheel 54 is provided with a brake device to complete the work therewith.

[0144] In the present invention, the worm gear connector is locked and connected to the bottom of the battery pack bracket 1 through a locking member; the worm gear transmission mechanism 42 has a self-locking function, and the worm gear transmission mechanism 42 can drive the various components on the battery pack bracket 1 to rotate back and forth horizontally.

[0145] In the present invention, the front and rear ends of the transverse connecting frame 41 are hingedly connected to the battery bracket 1 and the lifting rod 63; the "hinge connection" referred to herein is a broad concept, which is a constraint mode in which two components are connected to each other and retain a certain degree of freedom for relative movement;

[0146] The hinge connection between the transverse connecting frame 41 and the battery bracket 1 is a limit connection constraint mode of the bearing seats at both ends, so that the battery bracket 1 has the freedom to rotate relative to the two axes of the transverse moving component 4, and limits the freedom in other directions;

[0147] The front and rear ends of the transverse connecting frame 41 are hingedly connected to the lifting rod 63. The hinge connection here is a constraint method similar to the gap hole connection. The nut on the top acts as a limiter to prevent the lifting rod 63 from separating from the transverse component 4. In fact, the hole size on the transverse component 4 is slightly larger than the size of the corresponding position on the lifting rod 63, so that there can be a small range of deflection between the lifting rod 63 and the transverse component 4 to ensure that when the heights of the front and rear lifting rods 63 are inconsistent, there is no jamming and inability to adjust. Therefore, it is called "hinge connection" here.

[0148] In the present invention, the axial rotation angle is achieved by a worm gear transmission mechanism 42. By rotating the handwheel of the worm gear transmission mechanism 42, the worm rotates and drives the worm wheel to rotate. Since the worm wheel and the battery pack bracket 1 are bolted together, the battery pack bracket 1 and the transverse displacement assembly 4 have relative rotational freedom, so the axial rotation angle adjustment and / or lateral rotation adjustment can be achieved.

[0149] In the present invention, the front moving wheels 52 are fixed wheels, and the rear moving wheels 54 are universal wheels.

[0158] The lifting transmission mechanism 64 is used to drive the adjusting gear 62 to rotate, and then control the lifting rod 63 to perform lifting movement, so as to drive the transverse movement component 4 and the battery bracket 1 and various components on the battery bracket 1 to move upward or downward.

[0159] In the present invention, the lifting transmission mechanism 64 includes: a lifting transmission mechanism mounting shell, the lifting transmission mechanism mounting shell is connected to the upper side of the frame 51; a lifting drive wheel, the lifting drive wheel is rotatably connected to the upper side of the lifting transmission mechanism mounting shell; a lifting drive wheel crank, the lifting drive wheel crank is connected to the outer side of the rotating shaft fixedly connected to the lifting drive wheel; a lifting driven wheel group, the lifting driven wheel group is rotatably connected to one end below the lifting transmission mechanism mounting shell; a lifting transmission member, one end of the lifting transmission member is meshed and connected with the first gear of the lifting driven wheel group, and the transmission bevel gear at the other end of the lifting transmission member is meshed and connected with the adjusting gear 62; a lifting transmission chain, the lifting transmission chain is arranged around the second gear of the lifting driven wheel group and the lifting drive wheel.

[0160] The working principle of the lifting assembly 6 is: the operator rotates the lifting drive wheel crank, and the lifting drive wheel crank drives the connected lifting drive wheel to rotate, and then the lifting drive wheel drives the second gear of the lifting driven wheel group to rotate through the lifting transmission chain, so that the second gear of the lifting driven wheel group rotates and drives the first gear fixedly connected to it to rotate, and then the first gear of the lifting driven wheel group rotates and drives the lifting transmission member meshing with it to rotate, so that the lifting transmission member drives the transmission bevel gear coaxially connected with it to rotate, and then the transmission bevel gear drives the adjusting gear 62 meshing with it to rotate on the adjusting member mounting seat 61, so that the adjusting member mounting seat 61 drives the lifting rod 63 threadedly connected to it to rotate, and finally, the lifting rod 63 drives the various components on the battery pack bracket 1 to move upward or downward.

[0162] In summary, a more specific embodiment of the present invention is:

[0163] Before using the mobile battery pack filling device of the above-mentioned design structure, the already manufactured filling device needs to be installed as a backup.

[0164] The specific steps are:

[0165] Example 1

[0166] When filling the battery pack 7:

[0167] Before use, the operator first installs the push head connector 313 on the push-pull block 31;

[0168] When in use: Step 1, the operator first selects a contact surface that matches the slide rail 23 according to the type of the battery pack 7. If the battery pack 7 is guided by a slider, the operator selects the rolling contact surface 232; if the battery pack 7 is guided by a roller, the operator selects the sliding contact surface 231;

[0169] Step 2: The operator adjusts the distance between the two slide rails 23 by using the adjustment components 21 of the two adjustment devices 2 according to the type of the battery pack 7;

[0170] Step 3: The operator places the battery pack 7 on the "U"-shaped mounting frame 11 of the battery pack bracket 1, and pushes the device to the vicinity of the battery shell section 8 of the vehicle through the push-pull handle 14, so that the front end of the battery pack bracket 1 faces the entrance of the battery shell section 8 of the vehicle;

[0171] Step 4: The operator adjusts the front and rear height of the battery bracket 1 by adjusting the lifting transmission mechanism 64 of the lifting assembly 6, and adjusts the axial rotation angle of the battery bracket 1 by adjusting the worm gear transmission mechanism 42 of the transverse movement assembly 4, and moves the entire loading device position so that the front ends of the two slide rails 23 on the mounting frame 11 are aligned and fit the two guide rails of the battery shell section 8 of the navigation body;

[0172] Step 5: The operator brakes and locks the front moving wheels 52 and the rear moving wheels 54 of the moving base 5;

[0173] Step six, the operator shakes the handle of the push-pull assembly 3 to move the push-pull block 31 behind the battery pack 7 forward, thereby pushing the battery pack 7 slowly into the battery shell section 8 of the navigation body to complete the loading of the battery pack 7.

[0174] Example 2

[0175] When removing the battery pack 7:

[0176] Step 1: The operator first selects a contact surface that matches the slide rail 23 according to the type of the battery pack 7 to be removed. If the battery pack 7 to be removed is guided by a slider, the operator selects the rolling contact surface 232; if the battery pack 7 to be removed is guided by a roller, the operator selects the sliding contact surface 231;

[0177] Step 2: The operator adjusts the distance between the two slide rails 23 by using the adjustment components 21 of the two adjustment devices 2 according to the type of the battery pack 7 to be removed;

[0178] Step 3: The operator pushes the device to the vicinity of the battery shell section 8 of the vehicle body by pushing and pulling the handle 14, so that the front end of the battery pack bracket 1 faces the entrance of the battery shell section 8 of the vehicle body;

[0179] Step 4: The operator adjusts the front and rear height of the battery bracket 1 by adjusting the lifting transmission mechanism 64 of the lifting assembly 6, and adjusts the axial rotation angle of the battery bracket 1 by adjusting the worm gear transmission mechanism 42 of the transverse movement assembly 4, and moves the entire loading device position so that the front ends of the two slide rails 23 on the mounting frame 11 are aligned and fit the two guide rails of the battery shell section 8 of the navigation body;

[0180] Step 5: The operator brakes and locks the front moving wheels 52 and the rear moving wheels 54 of the moving base 5;

[0181] In step six, the operator shakes the handle of the push-pull assembly 3 to move the push-pull block 31 forward until the push-pull block 31 is pushed to the front end of the mounting frame 11, and then connects the push-pull block 31 to the battery pack 7 to be removed through the stud bolt connector 314. Then, the operator shakes the handle of the push-pull assembly 3 to move the push-pull block 31 backward until the push-pull block 31 pulls the battery pack 7 to be removed out of the battery shell section 8 of the navigation body, thereby completing the removal of the battery pack 7 to be removed.

[0182] During the above-mentioned use, if it is necessary to fine-tune the lateral position of the front end of the slide rail 23 and the two guide rails of the battery shell section 8 of the vehicle body, one of the following two methods can be adopted to achieve it. The first adjustment method is: the operator releases the braking components on the front moving wheels 52 and the rear moving wheels 54 on the movable base 5, and moves the entire device laterally to align the front end of the slide rail 23 with the two guide rails of the battery shell section 8 of the vehicle body. After the adjustment is completed, the front moving wheels 52 and the rear moving wheels 54 are braked and locked; the second adjustment method is: the operator adjusts the lateral position of the battery pack bracket 1 by turning the handwheel on the worm gear transmission mechanism 42 to align the front end of the slide rail 23 with the two guide rails of the battery shell section 8 of the vehicle body, thereby completing the fine-tuning work.

[0183] If the distance between the two slide rails 23 needs to be adjusted, the operator rotates the adjustment disks of the adjustment components 21 on both sides respectively, which can drive the two slide rails 23 to move closer to or away from each other, thereby adjusting the distance and plane angle of the two slide rails 23;

[0184] If the contact surface of the slide rail 23 needs to be replaced, the operator only needs to rotate the slide rail 23 axially 180 degrees or take out the slide rail 23 and rotate it 180 degrees, and then install it, so as to adjust the contact surface of the slide rail 23 and the battery pack 7 to adapt to each other; after adjustment, it is convenient for the battery pack 7 to be located above the contact surface between the two slide rails 23, thereby reducing the friction during movement and effectively protecting the integrity of the battery pack 7.

[0185] Finally, it should be noted that the above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention still belongs to the protection scope of the technical solution of the present invention.
