[0055] In the description of the present invention, "plurality" means two or more than two, and "several" means one or more.

[0056] The vehicle power supply device 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings. The vehicle power supply device 1 can be connected to a vehicle as a current taking device, or can be connected to a charger as a current granting device.

[0057] like Figure 1-Figure 4As shown, the vehicle power supply device 1 according to the embodiment of the present invention includes a fixing seat 100 , a scissor-type lifting mechanism 200 , a power supply head 300 , a protection chain 500 and a power supply line 600 .

[0058] The scissor-type lifting mechanism 200 is installed on the fixed seat 100, and the scissor-type lifting mechanism 200 is used to be lifted and lowered under the drive of the driving device 400. The power supply head 300 is installed on the scissor-type lifting mechanism 200 and is driven to be lifted and lowered by the scissor-type lifting mechanism 200. One end of the protection chain 500 is installed on the fixed seat 100 and the other end is installed on the power supply head 300, and a cable accommodating chamber 510 is constructed in the protection chain 500. The power supply line 600 is arranged in the cable accommodating chamber 510 and is connected to the power supply head 300.

[0059] For example, the fixing seat 100 is horizontally arranged, and the scissor-type lifting mechanism 200 is installed on the fixing seat 100, and can be retracted or expanded in the vertical direction. The power supply head 300 is installed on the scissor-type lifting mechanism 200, and as the scissor-type lifting mechanism 200 rises and falls, for example, when the scissor-type lifting mechanism 200 is expanded, the power supply head 300 descends; when the scissor-type lifting mechanism 200 is retracted, the power supply head 300 rises. One end of the protection chain 500 is installed on the fixing seat 100, and the other end is installed on the power supply head 300. When the scissor-type lifting mechanism 200 is in the retracted state, the protection chain 500 can be U-shaped. The protection chain 500 is internally structured with a cable accommodating cavity 510, and the power supply line 600 is arranged in the cable accommodating cavity 510. The end of the power supply line 600 passes through the cable accommodating cavity 510 and is connected to the power supply head 300 to achieve electrical connection.

[0060] According to the vehicle power supply device 1 of the embodiment of the present invention, by providing a protection chain 500 and constructing a cable accommodating cavity 510 therein, the power supply line 600 can be inserted into the cable accommodating cavity 510. In this way, the protection chain 500 can not only protect the power supply line 600, but also prevent the power supply line 600 from being damaged by contact and friction with other components, thereby improving the service life of the power supply line 600. In addition, the protection chain 500 can adapt to the lifting and lowering of the power supply head 300, thereby not affecting the smoothness of the lifting and lowering of the power supply head 300. In addition, the cable accommodating cavity 510 of the protection chain 500 can standardize the arrangement of the power supply line 600, so that the wiring harness of the vehicle power supply device 1 is neatly arranged.

[0061] Therefore, the vehicle power supply device 1 according to the embodiment of the present invention can have the advantages of safety, reliability, neat wiring harness arrangement, etc.

[0062] The power supply line 600 may be a flexible flat cable to achieve flexible movement and protection of the cable. The flexible flat cable may be used together with the protection chain 500 or may be used alone.

[0063] In some specific embodiments of the present invention, Figure 1-Figure 5As shown, the protection chain 500 includes a plurality of links 520 , each of which has an inner cavity. Adjacent links 520 are hinged, and the inner cavities of the plurality of links 520 are collectively configured to form a cable accommodating cavity 510 .

[0064] Specifically, the link 520 includes a base frame 521 , a first outer connecting ear 522 , a second outer connecting ear 523 , a first inner connecting ear 524 and a second inner connecting ear 525 .

[0065] The base frame 521 is annular, such as a rectangular ring. The first outer connecting ear 522 and the second outer connecting ear 523 are arranged at one side of the base frame 521 and are spaced apart. The first inner connecting ear 524 and the second inner connecting ear 525 are arranged at the other side of the base frame 521 and are spaced apart.

[0066] Among them, for two adjacent links 520, the first inner connecting ear 524 of one link 520 is arranged on the inner side of the first outer connecting ear 522 of the other link and the two are hinged, and the second inner connecting ear 525 of one link 520 is arranged on the inner side of the second outer connecting ear 523 of the other link 520 and the two are hinged.

[0067] For example, the first outer connecting ear 522 and the second outer connecting ear 523 are arranged at two ends of the base frame 521 at intervals in the width direction of the protection chain 500. The first inner connecting ear 524 is located inside the first outer connecting ear 522 in the width direction of the protection chain 500, and the second inner connecting ear 525 is located inside the second outer connecting ear 523 in the width direction of the protection chain 500.

[0068] In the length direction of the protection chain 500 , the first outer connecting ear 522 and the second outer connecting ear 523 are located on one side of the base frame 521 , and the first inner connecting ear 524 and the second inner connecting ear 525 are located on the other side of the base frame 521 .

[0069] Thus, the first inner connecting ear 524 and the second inner connecting ear 525 of one link 520 of two adjacent links 520 can be inserted into the space between the first outer connecting ear 522 and the second outer connecting ear 523 of the other link 520. In addition, the first outer connecting ear 522 of the other link 520 is hinged to the first inner connecting ear 524 of the one link 520, and the second outer connecting ear 523 of the other link 520 is hinged to the second inner connecting ear 525 of the one link 520.

[0070] The first outer connecting ear 522 , the second outer connecting ear 523 , the first inner connecting ear 524 , the second inner connecting ear 525 and the base frame 521 may be integrally formed.

[0071] In this way, the protection chain 500 can be easily changed, has a simple structure, is highly applicable, and can achieve the function of protecting the power supply line 600, and can be deformed as the power supply head 300 rises and falls.

[0072] Optionally, one side edge of the first outer connecting ear 522 , the second outer connecting ear 523 , the first inner connecting ear 524 , and the second inner connecting ear 525 away from the base frame 521 may be configured to be arc-shaped, so that the relative rotation of two adjacent chain links 520 is smoother.

[0073] In some specific embodiments of the present invention, Figure 1 , Figure 2 , Figure 4 As shown, the fixing seat 100 is provided with a first mounting frame 120, the power supply head 300 is provided with a second mounting frame 380, the plurality of chain links 520 at one end of the protection chain 500 are mounted on the first mounting frame 120, and the plurality of chain links 520 at the other end of the protection chain 500 are mounted on the second mounting frame 380. Thus, the two ends of the protection chain 500 can be made smoother, thereby preventing the power supply line 600 from being bent too much at the two ends of the protection chain 500, further improving the power supply stability of the power supply line 600, and avoiding interference with the scissor-type lifting mechanism 200.

[0074] Optionally, the first mounting bracket 120 and the second mounting bracket 380 are located at corresponding positions and are located on the same side of the scissor-type lifting mechanism 200 .

[0075] Specifically, the first mounting frame 120 and the second mounting frame 380 of the protection chain 500 passed through by the same power supply line 600 are located on the same side of the scissor-type lifting mechanism 200. For example, for the power supply line 600 located on the left side of the scissor-type lifting mechanism 200, the first mounting frame 120 matched therewith is on the left side of the scissor-type lifting mechanism 200, and the second mounting frame 380 matched therewith is also on the left side of the scissor-type lifting mechanism 200; for the power supply line 600 located on the right side of the scissor-type lifting mechanism 200, the first mounting frame 120 matched therewith is on the right side of the scissor-type lifting mechanism 200, and the second mounting frame 380 matched therewith is also on the right side of the scissor-type lifting mechanism 200. In this way, the structure of the vehicle power supply device 1 can be made more reasonable and the movement performance can be better.

[0076] In some specific embodiments of the present invention, Figure 4 and Figure 7 As shown, the driving device 400 includes a driving unit 700 and a transmission unit 800 for converting rotational motion into linear motion. The driving unit 700 is connected to the scissor-type lifting mechanism 200 through the transmission unit 800 to drive the scissor-type lifting mechanism 200 to rise and fall.

[0077] Thus, the drive device 400 includes a drive unit 700 and a transmission unit 800, and the transmission unit 800 can convert rotational motion into linear motion. Therefore, due to the change in the driving force transmission path, the form of the drive unit 700 can be more diversified, for example, by using a method other than hydraulic pressure, such as a motor, etc., so that the drive device 400 does not swing when driving the scissor-type lifting mechanism 200 to rise and fall, thereby improving stability, thereby improving the smoothness of the movement of the power supply head 300, and thus facilitating alignment during charging. In addition, since the drive device 400 integrates the transmission unit 800, and based on the change of the driving force path by the transmission unit 800, the arrangement of the drive unit 700 and the transmission unit 800 can be made more flexible, such as a stacked arrangement, which can reduce the space occupied by the drive device 400, thereby facilitating the arrangement of the overall structure of the vehicle power supply device 1.

[0078] In some specific embodiments of the present invention, Figure 4 and Figure 7 As shown, the driving device 400 is installed on the fixed seat 100, and the transmission unit 800 is located between the fixed seat 100 and the driving unit 700. For example, the fixed seat 100 is horizontally arranged, and the scissors-type lifting mechanism 200 is arranged on the upper surface of the fixed seat 100. The driving device 400 is installed on the upper surface of the fixed seat 100 and is located below the scissors-type lifting mechanism 200, and the transmission unit 800 is located above the fixed seat 100. The driving unit 700 is located above the transmission unit 800, thereby the driving device 400 can be stably fixed on the fixed seat 100, and the position remains unchanged during operation. In addition, the arrangement of the driving unit 700 and the transmission unit 800 occupies a smaller space, and the output of the driving force is more stable.

[0079] Specifically, the driving device 400 further includes a housing 900, the housing 900 is mounted on the fixing base 100, the transmission unit 800 is disposed in the housing 900, and the driving unit 700 is mounted on the housing 900 and extends into the housing 900 to be connected with the transmission unit 800. The housing 900 can not only fix the driving device 400 as a whole on the fixing base 100, but also integrate the driving unit 700 and the transmission unit 800 into a whole and play a protective role.

[0080] In some specific examples of the present invention, Figure 7 As shown, the transmission unit 800 includes a driving screw 810 and a driven screw 820 .

[0081] The active lead screw 810 is connected to the driving unit 700 and driven to rotate by the driving unit 700. The driven lead screw 820 is threadedly connected to the active lead screw 810 and converts the rotational motion of the active lead screw 810 into the linear motion of the driven lead screw 820, and the driven lead screw 820 is connected to the scissor lift mechanism 200.

[0082] For example, the driven screw 820 is a hollow structure, the active screw 810 extends into the driven screw 820, the active screw 810 is constructed with an external thread 811 and the driven screw 820 is constructed with an internal thread 821 that cooperates with the external thread 811, and the external thread 811 and the internal thread 821 can be respectively constructed on the relatively larger diameter parts of the active screw 810 and the driven screw 820.

[0083] Thus, the driving unit 700 drives the active lead screw 810 to rotate, and the active lead screw 810 drives the driven lead screw 820 to move linearly when rotating, and the linear movement of the driven lead screw 820 is used to drive the scissor-type lifting mechanism 200 to move up and down.

[0084] Specifically, a slide groove 870 is provided on one of the driven screw 820 and the housing 900 and a slide rib 880 is provided on the other. The slide rib 870 and the slide groove 880 are slidably matched and both extend along the axial direction of the driven screw 820 .

[0085] For example, the slide groove 870 is arranged on the outer peripheral surface of the part with a larger diameter of the driven lead screw 820 and extends along the axial direction of the driven lead screw 820, and the slide bar 880 is arranged on the housing 900, and the slide bar 880 is relatively long. The slide bar 880 and the slide groove 870 can be slidably matched, so as to circumferentially position the driven lead screw 820, prevent the driven lead screw 820 from rotating, and allow the driven lead screw 820 to slide axially. In this way, when the active lead screw 810 rotates, the driven lead screw 820 moves linearly, and in order to ensure the reliability of the matching between the slide bar 880 and the slide groove 870, the slide groove 870 can be arranged on the lower surface of the driven lead screw 820, and accordingly, the slide bar 880 is arranged on the bottom wall of the housing 900.

[0086] In some embodiments of the present invention, Figure 7 As shown, the driving unit 700 is a motor, and the transmission unit 800 further includes a driving wheel 830 , a driven wheel 840 and a transmission belt 850 .

[0087] The driving wheel 830 is drivingly connected to the motor shaft of the motor, the driven wheel 840 is drivingly connected to the driving screw 810 , and the transmission belt 850 is sleeved on the driving wheel 830 and the driven wheel 840 .

[0088] After the motor is running, the motor shaft drives the driving wheel 830 to rotate, the driving wheel 830 drives the driven wheel 840 to rotate through the transmission belt 850, and the driven wheel 840 drives the driving screw 810 to rotate.

[0089] Therefore, the driving unit 700 and the transmission unit 800 can be arranged side by side, that is, axially parallel, so that the driving unit 700 is arranged above the transmission unit 800 to form a stacked arrangement.

[0090] Those skilled in the art will appreciate that, in the embodiment of the present invention, the specific form of the transmission unit 800 is not limited to the combination of a screw and a belt, but may also be a combination of one or more of a screw, a gear, a belt, and a pulley.

[0091] In some specific examples of the present invention, Figure 7 As shown, the housing 900 includes a cylinder 910 , a plug 920 , an intermediate cylinder 930 , an intermediate cover 940 and an end cover 950 .

[0092] The driven lead screw 820 is disposed in the cylinder 910, and the sliding bar 880 can be disposed on the cylinder 910. The plug 920 is disposed at one end of the cylinder 910, and the plug 920 extends from the end of the driven lead screw 820 away from the active lead screw 810. The intermediate cylinder 930 is disposed at the other end of the cylinder 910, and the active lead screw 810 is supported on the intermediate cylinder 930 through a bearing 931. The intermediate cover 940 is disposed in the intermediate cylinder 930, and the driving unit 700 is installed on the intermediate cover 940. The end cover 950 is disposed in the intermediate cover 940, and the driving wheel 830, the driven wheel 840 and the transmission belt 850 are disposed in the end cover 950.

[0093] Thus, the housing 900 integrates the driving unit 700 and the transmission unit 800 into a whole, and the split setting of the housing 900 facilitates the disassembly and assembly of the driving device 400 and facilitates subsequent maintenance.

[0094] Among them, a joint 860 is provided at one end of the driven lead screw 820 away from the active lead screw 810 (ie, the end extending out of the plug 920 ), and the driven lead screw 820 is connected to the scissor-type lifting mechanism 200 via the joint 860 .

[0095] In some specific embodiments of the present invention, Figure 1 , Figure 2 , Figure 4 As shown, the scissor-type lifting mechanism 200 includes at least one scissor-type swing arm assembly 210 .

[0096] The scissor-type swing rod assembly 210 includes at least one pair of swing rods 211, each pair of swing rods 211 includes two swing rods 211 that are cross-arranged and hinged to each other. In an embodiment with multiple pairs of swing rods 211, the ends of the swing rods 211 in two adjacent pairs of swing rods 211 are respectively hinged, and the two swing rods 211 in the pair of swing rods 211 closest to the fixing seat are respectively installed on the fixing seat 100. The power supply head 300 is installed on the two swing rods 211 in the pair of swing rods 211 farthest from the fixing seat 100.

[0097] Specifically, the fixed seat 100 is arranged horizontally, and the scissor-type lifting mechanism 200 is installed on the fixed seat 100, and can be retracted or unfolded in the vertical direction. The scissor-type swing rod group 210 includes a plurality of pairs of swing rods 211, each pair of swing rods 211 includes two swing rods 211 that are cross-arranged and hinged to each other, and the ends of the swing rods 211 in two adjacent pairs of swing rods 211 are hinged respectively, and through these hinge points, the folding and extension of the swing rods 211 are realized, thereby realizing telescoping. The two swing rods 211 connected to the power supply head 300 are arranged on a horizontal plane on one side of the power supply head 300 close to the fixed seat 100, and are respectively adjacent to the left and right ends of the power supply head 300.

[0098] In this way, by connecting the ends of the two rocker arms 211 of the scissor-type lifting mechanism 200 to the power supply head 300, not only the structure is simpler, but the two rocker arms 211 are cross-arranged, which can make the power supply head 300 more stable during movement and reduce the swing of the power supply head 300, thereby facilitating alignment during power supply and improving the reliability of power supply performance.

[0099] Those skilled in the art need to understand that the form of the lifting mechanism of the present invention is not limited to the scissors-type lifting mechanism. For example, replacing the scissors-type lifting mechanism with a multi-link lifting mechanism, a guided telescopic column lifting mechanism, a linear slide rail lifting mechanism, etc. is also within the scope of protection of the present invention and is a simple replacement or modification of the present invention, and does not deviate from the principle and purpose of the present invention.

[0100] In some specific embodiments of the present invention, Figure 1 , Figure 2 , Figure 4 As shown, one of the pair of rocker arms 211 closest to the fixed seat 100 is hinged on the fixed seat 100, and the other of the pair of rocker arms 211 closest to the fixed seat 100 is slidably mounted on the fixed seat 100, and the driving device 400 drives the other of the pair of rocker arms 211 closest to the fixed seat 100 to slide on the fixed seat 100.

[0101] Specifically, a first guide rail 110 is provided on the fixed seat 100, and the other one of the pair of rocker arms 211 closest to the fixed seat 100 is hinged with a first slide bar 240, which is slidably engaged with the first guide rail 110, and the driving unit 700 is connected to the first slide bar 240 through the transmission unit 800.

[0102] Furthermore, two opposite side surfaces of the first guide rail 110 are respectively provided with first grooves 111 extending along the length direction of the first guide rail 110 , and a first slider 241 is provided on the first slide bar 240 . The first slider 241 is constructed with first clamping claws 242 respectively matched in the first grooves 111 .

[0103] For example, one of the two lowest swing arms 211 of the scissor-type swing arm group 210 is hinged to the fixed seat 100, and the other swing arm 211 is hinged to the first slide bar 24. The first guide rail 110 is provided with first grooves 111 on the front and rear sides, respectively, and the first grooves 111 extend in the left and right directions. The first slide bar 240 is provided with a first slider 241, and the first slider 241 can be connected to the first slide bar 240 through a threaded fixing member (for example, a bolt). The first slider 241 is configured with a first clamping jaw 242, and the first clamping jaw 242 can be slidably engaged with the first groove 111. The first clamping jaw 242 cannot be disengaged due to being stopped by the upper wall of the first groove 111, and can only slide along the length direction of the first groove 111.

[0104] Therefore, through the setting of the first guide rail 110 and the first slide bar 240, the other one of the pair of rocker arms 211 closest to the fixed seat 100 can be slidably installed on the fixed seat 100, and the first guide rail 110 is provided with a first groove 111, and the first slide bar 240 is provided with a first slider 241 with a first clamp 242. Through the cooperation of the first clamp 242 and the first groove 111, the stability of the first slide bar 240 on the first guide rail 110 can be guaranteed, and the first slide bar 240 can be prevented from falling off the first guide rail 110.

[0105] In some specific examples of the present invention, Figure 3 As shown, the accompanying drawings show an example in which the driving unit 700 is a servo motor, and the transmission unit 800 is connected to the first slide bar 240 through the push rod 410. Specifically, in the transmission unit 800, the driven screw 820 is connected to the push rod 410 through the joint 860 thereon, and when the driven screw 820 performs linear motion, it drives the push rod 410 to perform linear motion, thereby driving the first slide bar 240 to slide along the first guide rail 110, wherein the setting of the joint 860 not only facilitates the connection between the driven screw 820 and the push rod 410, but is also suitable for connecting push rods 410 of different specifications, and the push rod 410 and the first slide bar 240 can be connected by threaded fasteners, such as bolts. The driving device 400 transmits the driving force to the first slide bar 240 through the push rod 410, thereby driving the entire scissor-type lifting mechanism 200 to rise and fall.

[0106] Optionally, the push rod 410 is arranged parallel to the fixing seat 100. In this way, the efficiency of the work done by the driving device 400 is the highest, the first slide bar 240 and the first guide rail 110 are not easily damaged, and the structure is stable. In addition, the driving device 400 pushes the first slide bar 240 in a horizontal manner, which can further improve the stability of the power supply head 300 during movement.

[0107] Of course, the push rod 410 can also be arranged at a certain angle with the fixing seat 100, as long as the push rod 410 can be normally extended and retracted.

[0108] In some specific embodiments of the present invention, Figure 1 , Figure 2 , Figure 4 As shown, one of the pair of swing rods 211 farthest from the fixing base 100 is hinged on the power supply head 300 , and the other of the pair of swing rods 211 farthest from the fixing base 100 is slidably mounted on the power supply head 300 .

[0109] Specifically, a second guide rail 310 is provided on the power supply head 300 , and the other one of the pair of swing rods 211 farthest from the fixing seat 100 is hinged with a second slide bar 250 , and the second slide bar 250 is slidably matched with the second guide rail 310 .

[0110] Furthermore, two opposite side surfaces of the second guide rail 310 are respectively provided with second grooves 311 extending along the length direction of the second guide rail 310 , and a second slider 251 is provided on the second slide bar 250 . The second slider 251 is constructed with second clamping claws 252 respectively matched in the second grooves 311 .

[0111] For example, one of the two uppermost swing arms 211 of the scissor-type swing arm group 210 is hinged to the power supply head 300, and the other swing arm 211 is hinged to the rear end of the second slide bar 250. The second guide rail 310 is provided with a second groove 311 on both the front and rear sides, and the second groove 311 extends in the left-right direction. The second slide bar 250 is provided with a second slider 251, and the second slider 251 can be connected to the second slide bar 250 by a threaded fastener (for example, a bolt). The second slider 251 is configured with a second clamping jaw 252, and the second clamping jaw 252 can be slidably engaged with the second groove 311. The second clamping jaw 252 cannot be disengaged due to being stopped by the lower wall of the second groove 311, and can only slide along the length direction of the second groove 311.

[0112] Therefore, through the setting of the second guide rail 310 and the second slide bar 250, the other one of the pair of rocker bars 211 farthest from the fixed seat 100 can be slidably installed on the power supply head 300, and the second guide rail 310 is provided with a second groove 311, and the second slide bar 250 is provided with a second slider 251 with a second clamp 252. Through the cooperation of the second clamp 252 and the second groove 311, the stability of the second slide bar 250 on the second guide rail 310 can be guaranteed, and the second slide bar 250 can be prevented from falling off the second guide rail 310.

[0113] In order to ensure the stability of the power supply head 300, the positions of the second slide bar 250 and the first slide bar 240 can be set correspondingly. For example, the accompanying drawings show an example in which the second slide bar 250 and the first slide bar 240 are both located on the right side of the scissors-type lifting mechanism 200.

[0114] In some specific embodiments of the present invention, Figure 1 and Figure 4 As shown, there are multiple scissors-type rocker arm groups 210, and the multiple scissors-type rocker arm groups 210 can be arranged at intervals in the front-to-back direction. The scissors-type lifting mechanism 200 includes a connecting rod 260, and the connecting rod 260 is connected between two adjacent scissors-type rocker arm groups 210 to enable the multiple scissors-type rocker arm groups 210 to be lifted and lowered synchronously. For example, the connecting rod 260 is respectively connected to the inner rocker arms 211 of two adjacent scissors-type rocker arm groups 210.

[0115] Among them, one of the pair of swing rods 211 closest to the fixed seat 100 in each scissors-type swing rod group 210 is hinged on the fixed seat 100, the other of the pair of swing rods 211 closest to the fixed seat 100 in each scissors-type swing rod group 210 is hinged to the first slide bar 240, one of the pair of swing rods 211 farthest from the fixed seat 100 in each scissors-type swing rod group 210 is hinged to the power supply head 300, and the other of the pair of swing rods 211 farthest from the fixed seat 100 in each scissors-type swing rod group 210 is hinged to the second slide bar 250.

[0116] For example, there are multiple scissor-type swing rod groups 210 and they are spaced apart in the front-to-back direction, and the connecting rods 260 are respectively connected to the inner swing rods 211 of two adjacent scissor-type swing rod groups 210, and the number is multiple. The top pair of swing rods 211 of the multiple scissor-type swing rod groups 210, the left swing rod 211 is hinged on the power supply head 300, and the right side is hinged on the second slide bar 250. The bottom pair of swing rods 211 of the multiple scissor-type swing rod groups 210, the left swing rod 211 is hinged on the fixed seat 100, and the right side is hinged on the first slide bar 240.

[0117] Therefore, by setting up multiple scissor-type swing arm groups 210, the stability of the power supply head 300 during lifting and lowering can be improved, and the setting of the connecting rod 260 can stabilize the relative positions between the multiple scissor-type swing arm groups 210, thereby improving the stability of the scissor-type lifting mechanism 200.

[0118] Furthermore, the scissor-type lifting mechanism 200 also includes a push rod 410, which is connected between the first slide bars 240 of two adjacent scissor-type swing arm groups 210. The driving device 400 is installed on the fixed seat 100 and drives multiple first slide bars 240 through the push rod 410.

[0119] It can be understood by those skilled in the art that, in an embodiment where there are more than two scissor-type swing arm groups 210, push rods 410 can be respectively provided between the first slide bars 240 of two adjacent scissor-type swing arm groups 210. In other words, the number of push rods 410 is one less than the number of scissor-type swing arm groups 210 and is the same as the number of first slide bars 240. When multiple push rods 410 are provided, the multiple push rods 410 are all connected to the driving device 400, so that the driving device 400 drives the multiple push rods 410 to synchronously drive the multiple first slide bars 240.

[0120] In some specific embodiments of the present invention, Figure 1-Figure 2 , Figure 4-Figure 5 As shown, the power supply head 300 includes a base frame 320 , a support plate 330 , a signal plate 350 and an electrode plate 340 .

[0121] Two of the pair of rocker arms 211 farthest from the fixed seat 100 are mounted on the base frame 320, the support plate 330 is mounted on the base frame 320 through the insulator 370, the electrode plate 340 and the signal plate 350 are respectively mounted on the corresponding support plates 330, for example, the electrode plate 340 and the signal plate 350 are respectively mounted on the corresponding support plates 330 through the elastic member 360, and the elastic member 360 can be a compression spring, a leaf spring or a plastic elastic member.

[0122] The other end of the protection chain 500 is installed on the base frame 320 , and the power supply line 600 is connected to the electrode plate 340 .

[0123] Those skilled in the art will appreciate that the number and location of the support plate 330 , the electrode 340 , the signal plate 350 , the elastic member 360 , and the insulator 370 can be set according to actual needs.

[0124] For example, Figure 6 As shown, the power supply head 300 may not be provided with the signal plate 350, and there are two electrode plates 340, which are arranged in parallel and along the length direction of the electrode plates 340 (such as Figure 2 The left and right directions in the figure are arranged alternately.

[0125] For example, Figure 5 As shown, there are three signal plates 350, and the three signal plates 350 are arranged in parallel and along the width direction of the signal plates 350 (such as Figure 5 There are two electrode plates 340, which are arranged in parallel and spaced apart along the width direction of the electrode plates 340. The two electrode plates 340 are respectively located on one side of the length direction of the two outermost signal plates 350. Specifically, the three signal plates 350 are respectively provided with three signal cables CAN+, CAN- and CAN ground to control the charging current during the charging process. The electrode plates 340 may have the function of providing high voltage (charging or discharging) current.

[0126] The vehicle power supply device 1 according to the embodiment of the present invention realizes active control of the charging process, reduces unnecessary charging times, and prolongs the service life of the charging device and the battery. When the vehicle enters the station, it can be charged according to the charging needs, avoiding the collision and impact noise between the charging devices when entering the station, and the power supply head rises and falls smoothly, which is conducive to alignment during power supply.
