[0034] like Figure 1 、 Figure 2 as well as Figure 7As shown, the present invention provides a charging house for patrol vehicles, comprising a charging house main body 1 and a patrol vehicle 2. The charging house main body 1 comprises an entrance and exit 101. The patrol vehicle 2 enters and exits the charging house main body 1 through the entrance and exit 101 to charge. A rolling shutter door 6 is provided at the top of the entrance and exit 101, and a liftable slope 7 is provided below the entrance and exit 101. A reinforcing support plate 701 is provided inside the liftable slope 7. The reinforcing support plate 701 serves to enhance the supporting strength of the liftable slope 7. When the patrol vehicle 2 needs to be charged, the liftable slope 7 will be lowered and the rolling shutter door 6 will be raised, making it convenient for the patrol vehicle 2 to enter the charging house main body 1 and reach the designated position for charging. When the patrol vehicle 2 is fully charged and drives out of the charging house main body 1, the rolling shutter door 6 will be lowered, the liftable slope 7 will be raised, and the process ends. The liftable slope 7 is rotatably connected to the charging house main body 1, thereby realizing rotational raising and reverse rotational lowering.

[0035] A charging bow mounting seat 3 is provided in the charging house main body 1, and the charging bow mounting seat 3 is fixed on the wall of the charging house main body 1. The charging bow mounting seat 3 is connected to the charging bow 4, and the charging bow 4 includes a scissor lever mechanism 401 and an upper charging plate 402. The upper end of the scissor lever mechanism 401 is connected to the charging bow mounting seat 3, and the lower end of the scissor lever mechanism 401 is connected to the upper charging plate 402; the scissor lever mechanism 401 is provided with a driving component 403, and the driving component 403 is used to control the extension and retraction of the scissor lever mechanism 401, that is, the purpose of controlling the lifting of the upper charging plate 402 is achieved through the driving component 403; a lower charging bow 201 is provided on the inspection car 2, and the lower charging bow 201 corresponds to the upper charging plate 402 in position and is used in conjunction with it; when the inspection car 2 needs to be charged, the driving component 403 controls the scissor lever mechanism 401 to move to control the upper charging plate 402 to descend and engage with the lower charging bow 201. When the upper charging plate 402 is pressed down, it makes cross contact with the electrodes of the lower charging bow 201 to start charging. Here, the upper charging plate 402 and the lower charging pantograph 201 are fully connected by upper and lower electrodes, providing a wide contact range. The pantograph installed on the inspection vehicle 2 has a front-to-back tolerance of 65 mm and a side-to-side tolerance of 100 mm, effectively reducing charging failures caused by excessive distance errors. After charging is complete, the drive assembly 403 controls the upper charging plate 402 to rise, separating it from the lower charging pantograph 201.

[0036] A mounting slot 202 is provided on the top of the inspection vehicle 2, and the lower charging bow 201 is connected to the mounting slot 202. The lower charging bow 201 can slide left and right on the mounting slot 202 to facilitate position adjustment. When the adjustment is completed, the lower charging bow 201 can be locked on the mounting slot 202.

[0037] like Figure 3 as well as Figure 4As shown, the charging bow mounting base 3 includes a first mounting plate 301, a second mounting plate 302 and a third mounting plate 303, an axis 304 and a first motor 305, including a first wall bracket 314 and a second wall bracket 315. The first mounting plate 301 and the second mounting plate 302 are welded to the first wall bracket 314, and the third mounting plate 303 is welded to the second wall bracket 315. The first wall bracket 314 and the second wall bracket 315 are locked to the charging house body 1.

[0038] The shaft body 304 is rotatably connected to the first mounting and fixing plate 301, the second mounting and fixing plate 302 and the third mounting and fixing plate 303; specifically, the shaft body 304 includes a shaft core 3041, which is a fixed part of the shaft body 304, and a first bearing 312 is provided in the first mounting and fixing plate 301, the inner ring of the first bearing 312 is connected to the shaft core 3041, and the outer ring of the first bearing 312 is connected to the first mounting and fixing plate 301; a second bearing 313 is provided in the second mounting and fixing plate 302, the inner ring of the second bearing 313 is connected to the shaft core 3041, and the outer ring of the second bearing 313 is connected to the second mounting and fixing plate 302, and the shaft body 304 is smoothly rotatably connected to the first mounting and fixing plate 301 and the second mounting and fixing plate 302 through the first bearing 312 and the second bearing 313; the connecting part between the shaft body 304 and the third mounting and fixing plate 303 can also be connected using the above-mentioned structure.

[0039] The shaft body 304 is connected to a suspension arm 306, which is provided with a first mounting plate 307. The first mounting plate 307 is used to connect with the charging bow 4. A driven gear 308 is provided on the shaft core 3041. The motor shaft of the first motor 305 is connected to the input shaft of the first reducer 309. The output shaft of the first reducer 309 is connected to the first coupling 310. The first coupling 310 is connected to the driving gear 311. The driving gear 311 is meshed with the driven gear 308. From the above structure, it can be seen that when the first motor 305 is started, the driving gear 311 is driven to rotate through the transmission of the first reducer 309 and the first coupling 310. Through the interaction between the driving gear 311 and the driven gear 308, the shaft body 304 is driven to rotate, that is, the charging bow 4 is driven to rotate. When charging is required, as shown in FIG. Figure 1 As shown, the charging bow 4 is controlled to rotate outward to the top of the inspection vehicle 2. When charging is completed, the charging bow 4 is controlled to rotate back inward to the inner wall of the charging room body 1.

[0040] A patrol vehicle repair tool storage cabinet 102 is provided in the main body 1 of the charging house. The patrol vehicle repair tool storage cabinet 102 is used to place vehicle repair tool parts for easy access; the charging bow mounting seat 3 is located above the patrol vehicle repair tool storage cabinet 102. After the charging bow mounting seat 3 drives the charging bow 4 to rise, it does not affect the use of the patrol vehicle repair tool storage cabinet 102.

[0041] The first wall bracket 314 is connected to a connecting plate 316 , and the first reducer 309 is connected and fixed to the connecting plate 316 , so the first motor 305 , the first reducer 309 and the first coupling 310 do not interfere with the rotation of the shaft 304 .

[0042] The boom 306 includes a horizontal bar 3061 and an oblique bar 3062 . The horizontal bar 3061 , the oblique bar 3062 and the shaft 304 are welded and fixed into a triangle shape, and the structure is stable. The first mounting plate 307 is connected and fixed to the horizontal bar 3061 .

[0043] like Figure 5 as well as Figure 6 As shown, the scissor lever mechanism 401 itself is shown in the figure, and is composed of a number of rods hinged in sequence, so it can be folded or extended. This is the existing structural technology of the scissor lever mechanism 401 and will not be described in detail here. In this design, a first assembly plate 4011 is provided on one side of the scissor lever mechanism 401, and a second assembly plate 4012 is provided on the other side. The driving component 403 includes a second motor 4031, a second reducer 4032, a ball screw 4033 and a screw sleeve 4034. The ball screw 4033 and the screw sleeve 4034 are used in conjunction with each other. The second reducer 4032 is connected and fixed to the second assembly plate 4012, the second motor 4031 is connected to the input end of the second reducer 4032, and the output end of the second reducer 4032 is connected to the ball screw 4033. The screw sleeve 4034 is connected and fixed on the first assembly plate 4011, and the first assembly plate 4011 and the second assembly plate 4012 are installed at the intersection of the rods in the scissor lever mechanism 401. Combined with the principle of screw transmission, it can be seen that the second motor 4031 starts and drives the ball screw 4033 to rotate through the second reducer 4032, which can control the screw sleeve 4034 to move on the ball screw 4033, thereby controlling the first assembly plate 4011 and the second assembly plate 4012 to approach or move away from each other, that is, ultimately achieving the purpose of controlling the extension and retraction of the scissor lever mechanism 401; an upper second mounting plate 4035 is connected to the top of the scissor lever mechanism 401, and the second mounting plate 4035 is connected and fixed to the first mounting plate 307, thereby fixing the charging bow 4 below the charging bow mounting seat 3.

[0044] Wire protection chains 5 for the wire group are provided on both sides of the second mounting plate 4035; one end of the wire protection chain 5 is connected to the second mounting plate 4035, and the other end of the wire protection chain 5 extends toward the upper charging plate 402, and the wire group is connected downward to the upper charging plate 402 through the wire protection chain 5.

[0045] The working principle of the present invention is that when the inspection car 2 needs to be charged, the lifting ramp 7 will be lowered, the rolling shutter door 6 will be raised, and the inspection car 2 enters the charging room main body 1 from the entrance and exit 101 to the designated position; at this time, the first motor 305 is started, the drive shaft 304 rotates, and the charging bow 4 rotates to the top of the inspection car 2, so that the upper charging plate 402 corresponds to the lower charging bow 201 up and down, and then the drive component 403 drives the scissor rod mechanism 401 to extend downward, that is, the upper charging plate 402 is pressed down to the lower charging bow 201 to start charging; after charging is completed, the drive component 403 controls the upper charging plate 402 to rise so that the upper charging plate 402 is separated from the lower charging bow 201, the first motor 305 rotates in the opposite direction, and the drive shaft 304 rotates in the opposite direction, and finally the boom 306 and the charging bow 4 are tightly attached to the inner wall of the charging room main body 1 without causing interference; the inspection car 2 leaves the entrance and exit 101, the lifting ramp 7 will rise, and the rolling shutter door 6 falls, waiting for the next round of charging of the inspection car 2.
