For example, in some embodiments of the present invention, the current-extracting electrode assembly 2 further includes a mounting seat, and the current-extracting conductive part 23 is connected to the top or bottom plate 1 of the vehicle body 200 through the mounting seat.

For another example, in other embodiments of the present invention, the first current collecting electrode assembly 2a and the first current-supplying electrode assembly 4a are both negative electrode assemblies, and the second current collecting electrode assembly 2b and the second current-supplying electrode assembly 4b are both positive electrode assemblies.

Therefore, in the charging process, when the current taking device 10 or the current teaching device 20 shakes, the buffer device 24 can provide a damping buffer for at least one of the current taking conductive part 23 and the current teaching conductive part 42, so that the binding surface between the current teaching conductive part 42 and the current taking conductive part 23 can be adjusted instantly along with the shaking, the contact surface and the binding surface can be always kept in a binding state, the current teaching conductive part 42 and the current taking conductive part 23 are always kept in good contact, poor contact between the current teaching conductive part 42 and the current taking conductive part 23 is avoided, the risk of electric arcs is avoided, and the safety and the reliability of the charging device 100 are effectively improved.

Specifically, when the current-taking conductive portion 23 is formed as a plate body, the current-feeding conductive portion 42 is formed as an at least partially spherical structure. When the current feeding conductive portion 42 is formed as a plate body, the current taking conductive portion 23 is formed as an at least partially spherical structure. Therefore, the contact surface and the matching surface can be guaranteed to be always kept in good contact in the charging process, the structure is simple, and the processing is convenient.

In some embodiments of the present invention, the current-feeding conducting part 42 is a table. The surface of the current feeding conductive part 42 includes a first plane 421 and a partial spherical surface, the partial spherical surface is a mating surface, and the first plane 421 is used for installing the current feeding conductive part 42. Referring to fig. 1 and 2, the outer surface of the feeding conductor 42 includes a first plane 421 and a partial spherical surface. Wherein, the first plane 421 may be formed on the top of the current feeding conductive part 42, and a partial spherical surface may be formed below the first plane 421.

For example, in some embodiments of the present invention, the flow guide device 20 further includes a fixing seat 41 and a fixing plate 3, the fixing seat 41 is mounted on the fixing plate 3, and the first plane 421 of the flow guide portion 42 is connected to a side of the fixing seat 41 (e.g., a lower side of the fixing seat 41 in fig. 1) far away from the fixing plate 3. Optionally, the fixing base 41 is an insulator, but is not limited thereto. Thus, the feeding conductor 42 can be easily attached to the fixed plate 3.

Thus, by providing the first plane 421, the current feeding conductive part 42 can be easily and securely mounted, which is advantageous for improving the mounting efficiency and the structural stability of the current feeding device 20.

Alternatively, the first plane 421 may be formed as a horizontal plane.

According to some embodiments of the present invention, a carbon slide 26 is provided on at least one of the contact surface and the mating surface. Specifically, the carbon slider 26 may be provided only on the contact surface, the carbon slider 26 may be provided only on the mating surface, and the carbon slider 26 may be provided on both the contact surface and the mating surface. The carbon slider 26 is made of a flexible material, and by providing the carbon slider 26 on at least one of the contact surface and the mating surface, rigid friction is avoided, and the charging efficiency of the charging device 100 is improved.

It will be appreciated that the carbon slide 26 overlies the outer surface of the contact or mating surfaces, and that the shape of the carbon slide 26 is adapted to the shape of the contact and mating surfaces.

According to some embodiments of the present invention, the contact surface is formed as a plane, the mating surface is formed as a spherical surface, the plurality of feeding conductive portions 42 are disposed at intervals in the first direction, and the length direction of the plurality of current-taking conductive portions 23 extends in the second direction perpendicular to the first direction. Here, the first direction may be a longitudinal direction of the base plate 1 (e.g., a left-right direction in fig. 1), and the second direction may be a width direction of the base plate 1 (e.g., a front-back direction in fig. 1).

Since the length direction of current-collecting conductive part 23 is perpendicular to the spacing direction of current-feeding conductive part 42, current-feeding conductive part 42 can cooperate with any one position in the length direction of current-collecting conductive part 23 to charge vehicle 1000 during charging. Thus, the requirement of the charging device 100 on the accuracy of the parking position of the vehicle 1000 is reduced, the convenience and flexibility of the charging device 100 are improved, and the charging efficiency is improved.

According to the utility model discloses a some embodiments, get and flow electrode assembly 2 and be equipped with threely, and three get and flow electrode assembly 2 and arrange along first direction interval, arbitrary adjacent two are got and are flowed electrode assembly 2's polarity opposite.

Specifically, the three current taking electrode assemblies 2 may be a first current taking electrode assembly 2a, a second current taking electrode assembly 2b and a third current taking electrode assembly 2c, respectively. The first current taking electrode assembly 2a, the second current taking electrode assembly 2b and the third current taking electrode assembly 2c are arranged at intervals in the first direction, the polarities of the first current taking electrode assembly 2a and the second current taking electrode assembly 2b are opposite, and the polarities of the second current taking electrode assembly 2b and the third current taking electrode assembly 2c are opposite.

The first direction may be a width direction of the vehicle 1000 or a longitudinal direction of the vehicle 1000.

It is understood that, when the second current-taking electrode assembly 2b is a positive electrode assembly, both the first current-taking electrode assembly 2a and the third current-taking electrode assembly 2c are negative electrode assemblies. When the second current-taking electrode assembly 2b is a negative electrode assembly, the first current-taking electrode assembly 2a and the third current-taking electrode assembly 2c are positive electrode assemblies. Therefore, the first current taking electrode assembly 2a and the second current taking electrode assembly 2b can form a pair of electrodes to be matched with the current supplying electrode assembly 4 of the current supplying device 20 to charge the vehicle 1000, the second current taking electrode assembly 2b and the third current taking electrode assembly 2c can form a pair of electrodes to be matched with the current supplying electrode assembly 4 of the current supplying device 20 to charge the vehicle 1000, so that the charging condition when the vehicle 1000 turns around can be met, and the current taking device 10 can be matched with the current supplying device 20 to charge the vehicle 1000 no matter which end of the vehicle 1000 enters the station first, so that the flexibility of the charging device 100 and the charging efficiency are improved.

For example, referring to fig. 5, in the width direction of the vehicle 1000, the first current extracting electrode assembly 2a and the third current extracting electrode assembly 2c are respectively located on both sides of the second current extracting electrode assembly 2 b. If the vehicle 1000 is driving in the forward direction (i.e. the vehicle head is located at the front end of the driving direction), the first current taking electrode assembly 2a and the second current taking electrode assembly 2b can cooperate with the current teaching device 20 to charge the vehicle 1000, and after the vehicle 1000 turns around (i.e. the vehicle head is located at the rear end of the driving direction), the second current taking electrode assembly 2b and the third current taking electrode assembly 2c can cooperate with the current teaching device 20 to charge the vehicle 1000.

According to some embodiments of the present invention, two of the current-drawing electrode assemblies 2 are symmetrically disposed about a central axis of the other current-drawing electrode assembly 2 in the second direction, which is perpendicular to the first direction.

For example, as shown in fig. 5, the first electrode assembly 2a and the third electrode assembly 2c are disposed symmetrically with respect to the central axis of the second electrode assembly 2b in the second direction. It will be appreciated that the first 2a, second 2b and third 2c current-extracting electrode assemblies are aligned in a first direction. Or the first current taking electrode assembly 2a and the second current taking electrode assembly 2b may be arranged in a staggered manner in the first direction and the second direction, and the third current taking electrode assembly 2c and the second current taking electrode assembly 2b may be arranged in a staggered manner in the first direction and the second direction.

Therefore, no matter the vehicle 1000 is running in the forward direction or in the turning around direction, the relative positions of the current taking electrode assembly 2 matched with the current teaching device 20 on the current taking device 10 and the current teaching device 20 are kept unchanged, so that the requirement on the running direction of the vehicle 1000 is reduced, the positions of the positive electrode assembly and the negative electrode assembly in the current teaching electrode assembly 42 of the current teaching device 200 do not need to be changed before and after the turning around, and the charging flexibility is further improved.

According to some embodiments of the present invention, the supporting plate 21 is provided with a first limiting groove, the current-taking conductive portion 23 is provided with a second limiting groove 211, one end (e.g., the upper end in fig. 2) of the buffering device 24 is fixed in the first limiting groove, and the other end (e.g., the lower end in fig. 2) of the buffering device 24 is fixed in the second limiting groove 211. Therefore, the buffer device 24 can be conveniently and firmly fixed between the support plate 21 and the current-taking conducting part 23, the position of the buffer device 24 is stable, the buffer effect of the buffer device 24 is ensured, a mounting seat of the buffer device 24 is not required, the structure is simple, and the processing is convenient.

In some embodiments of the present invention, referring to fig. 3, a side surface of the current-taking conductive portion 23 adjacent to the supporting plate 21 is provided with a first boss 231, a side of the supporting plate 21 adjacent to the current-taking conductive portion 23 is provided with a second boss 210, the first limiting groove is provided in the first boss 231, and the second limiting groove 211 is provided in the second boss 210. From this, through setting up first spacing groove on first boss 231, set up second spacing groove 211 on second boss 210, not only can conveniently form first spacing groove and second spacing groove 211, can also improve the structural strength of current-conducting plate 23 through first boss 231, improve the structural strength of backup pad 21 through second boss 210 to the overall structure intensity of electrode assembly 2 has been improved.

Wherein the first bosses 231 may be fixed to the conductive plate 23 by screws, and the second bosses 210 may be fixed to the support plate 21 by screws. Simple structure and convenient assembly.

Further, the electrode assembly further includes a guide post 25 and a limiting member, a through hole is provided on the support plate 21, the guide post 25 is inserted into the buffer device 24, and one end (e.g., the lower end in fig. 3) of the guide post 25 away from the current-taking conductive portion 23 passes through the through hole and is connected to the limiting member. The stopper is provided spaced apart from the support plate 21. After the guide post 25 moves a distance toward the direction close to the current-taking conducting portion 23, the limit member can be in abutting fit with the lower surface of the support plate 21, so as to limit the guide post 25 from continuing to move upward. Thereby, the damping device 24 can be guided by the guide posts 25, so that the movement of the damping device 24 is more smooth.
