FIG. 2A is a schematic diagram of the charging system 100 according to an embodiment of the present disclosure, and FIG. 2B is a side view of the fixing device 110 of the charging system 100 of FIG. 2A.

The charging system 100 includes a tire sensor 105, a fixing device 110 and a fixing device 110', a charging end controller 130 and a blocking body 140. The charging end controller 130 can be integrated in the blocking body 140 or can be disposed outside the blocking body 140. .

The tire sensor 105 is disposed on the front surface 140u of the body 140 to sense whether the axle assembly 205 (shown in FIG. 3A) of the electric vehicle 200 (shown in FIG. 3A) has entered the fixture 110. The electric vehicle 200 of the present embodiment is described by taking a two-wheeled electric vehicle as an example, but it may be a single-wheel, three-wheel, four-wheel or other number of electric vehicles.

In an embodiment, when the blocking body 140 is movable, the charging system 100 may further include a hydraulic buffer (not shown) connected to the rear surface of the blocking body 140 (not shown) to receive the impact force of the vehicle. . In the present embodiment, the tire sensor 105 is disposed on the rear surface of the stopper 140, and the tire sensor 105 is triggered by the displacement of the stopper 140 to an appropriate position to sense the electric vehicle 200 (shown in FIG. 3A). Whether the axle assembly 205 (shown in Figure 3A) has entered the fixture 110.

In the present embodiment, the tire sensor 105 can be a mechanical switch, such as a limit switch, that senses whether the axle set 205 has entered the fixture 110 in a contact manner; in another embodiment, the tire sensor 105 can be An optical sensor or ultrasonic sensor that senses whether the axle set 205 has entered the fixture 110 in a contactless manner.

The first electrical transmission line 117 and the cleaning element 118.

In the present embodiment, the first clamping arm 111 is located above the driving mechanism 115, and the second clamping arm 114 is located below the driving mechanism 115; in another embodiment, the first clamping arm 111 can be located at the driving mechanism 115. Below, the second clamp arm 114 can be located above the drive mechanism 115. In addition, the first clamping arm 111 and/or the second clamping arm 114 are, for example, conductive clip arms, but may also be insulating clip arms.

The first clamping arm 111 has a first recess 111r, and the first conductive portion 112 is disposed in the first recess 111r. The first conductive portion 112 is for electrically contacting an axle assembly 205 (shown in FIG. 3A ) of an electric vehicle 200 (shown in FIG. 3A ).

The first clamping arm 111 has a sliding slot 111a, and the first conductive portion 112 is movably disposed in the sliding slot 111a. For example, the first elastic member 1131 is disposed in the sliding groove 111a and connects the first conductive portion 112 and the groove bottom surface 111w of the sliding groove 111a. Since the first elastic member 1131 has elasticity, the first conductive portion 112 can be moved up and down in the sliding groove 111a.

As shown in FIG. 2B, the first conductive portion 112 may have a multilayer structure. For example, the first conductive portion 112 includes a conductive probe 1121 and an insulating layer 1122, wherein the conductive probe 1121 is for electrically contacting the axle set 205 (the axle set 205 is shown in FIG. 3A), and the insulating layer 1122 can be coated with conductive The probe 1121 prevents the conductive probe 1121 from electrically contacting the first clamp arm 111. The first electrical transmission line 117 can be connected to The conductive probe 1121 extends outside the first clamping arm 111 and is electrically connected to the charging end controller 130.

The second clamp arm 114 has a second recess 114r. The axle assembly 205 (shown in FIG. 3A) of the electric vehicle can be clamped between the first recess 111r and the second recess 114r. For example, the driving mechanism 115 can connect the first clamping arm 111 and the second clamping arm 114 to drive at least one of the first clamping arm 111 and the second clamping arm 114 to rotate, and the axle assembly 205 of the electric vehicle 200 (painted Shown in FIG. 3A) is sandwiched between the first groove 111r and the second groove 114r. In the present embodiment, the drive mechanism 115 is a cam, but the disclosed embodiment is not limited thereto. As long as it is a mechanism that can drive at least one of the first clamp arm 111 and the second clamp arm 114 to clamp and release the axle set, the drive mechanism 115 of the disclosed embodiment can be used.

The fixture 110 shown in Fig. 2B is in a relaxed or released state. In this state, the long axis 1151 of the drive mechanism 115 is substantially parallel to the longitudinal direction of the first clamp arm 111 and the second clamp arm 114, and the second elastic member 1132 is in a free state. The second elastic element 1132 is connected to the inner side of the first clamping arm 111 and the inner side of the second clamping arm 114. When the first clamping arm 111 and the second clamping arm 114 rotate, the second elastic element 1132 can be deformed to store the elastic potential energy. In this way, when the driving mechanism 115 is rotated from other orientations to the longitudinal axis 1151 thereof substantially parallel to the orientation of the first clamping arm 111 and the second clamping arm 114, the second elastic component 1132 can release the elastic potential energy to drive the first The clamp arm 111 and the second clamp arm 114 are returned to the released state as shown in FIG. 2B.

One side of 1141. In another embodiment, the second elastic element 1132 can be located on the other side of the first pivot point 1111 of the first clamp arm 111 and the other side of the second rotation pivot point 1141 of the second clamp arm 114.

In addition, the driving mechanism 115 and the groove (the first groove 111r and the second groove 114r) may be respectively located at the first rotation fulcrum 1111 of the first clamping arm 111 (or the second rotation fulcrum 1141 of the second clamping arm 114) In another embodiment, the driving mechanism 115, the first groove 111 and the second groove may be located at the first pivot point 1111 of the first clamp arm 111 (or the second pivot point of the second clamp arm 114) 1141) on the same side.

In another embodiment, the first clamping arm 111 can omit the first rotating fulcrum 1111 or the second clamping arm 114 can omit the second rotating fulcrum 1141, so that when the driving mechanism 115 is running, only the first concave can be driven. The groove 111r rotates with one of the second grooves 114r.

In addition, as shown in FIG. 2B, there is an inlet 110a between the first clamping arm 111 and the second clamping arm 114. The inner diameter h of the inlet 110a is smaller than the outer diameter d of the axle assembly 205 (shown in FIG. 3A). Shown in Figure 5). The cleaning element 118 is disposed on the first clamp arm 111 and adjacent to the inlet 110a. Since the inner diameter h of the inlet 110a is smaller than the outer diameter d of the axle set 205, the cleaning element 118 can be cleaned when the axle set 205 (shown in Figure 3A) enters the inlet 110a. In this way, the resistance between the axle set 205 (shown in FIG. 3A) and the first conductive portion 112 can be reduced. In an embodiment, the cleaning element 118 is, for example, a steel brush, sandpaper, or other suitable component.

In addition, the insulating member 116 is disposed on the groove wall of the first groove 111r to separate From the first clamp arm 111 and the axle set 205, electrical shorting between the two is avoided. For example, the first groove 111r has a first side 111s1 and a second side 111s2 and a groove bottom surface 111s3. The insulating member 116 includes a first insulating portion 1161, a second insulating portion 1162, and a third insulating portion 1163. The first insulating portion 1161 is disposed on the first side surface 111s1 of the first recess 111r, the second insulating portion 1162 is disposed on the second side surface 111s2 of the first recess 111r, and the third insulating portion 1163 is disposed in the first recessed portion The groove bottom surface 111s3 of the groove 111r. Similarly, another insulating member 116 may be disposed on the groove wall of the second recess 114r to isolate the second clamp arm 114 from the axle assembly 205 (shown in FIG. 3A) to avoid electrical shorting between the two.

The tire 220 of the present embodiment is described by taking the front wheel as an example, but it may also be a tire of a rear wheel or other position.

As shown in FIG. 3B, each axle set 205 includes a conductive sleeve 211, a first insulating gasket 212, a second insulating gasket 213, a second electrical transmission line 214 (shown in FIG. 3A), a first fixing member 215, and a second Fixing member 216. The conductive sleeve 211 includes a first end surface 211s1 and a second end surface 211s2. The first insulating gasket 212 is disposed on the first end surface 211s1 of the conductive sleeve 211. The second insulating gasket 213 is disposed on the second end surface 211s2 of the conductive sleeve 211.

The conductive sleeve 211, the first insulating gasket 212 and the second insulating gasket 213 respectively include a first through hole 211a, a second through hole 212a and a third through hole 213a which are overlapped. The axle 230 passes through the first through hole 211a, the second through hole 212a, and the third through hole 213a. The first fixing member 215 and the second fixing member 216 are fixed to the axle 230, and the conductive sleeve 211, the first insulating gasket 212 and the second insulating gasket 213 are fixed between the first fixing member 215 and the second fixing member 216. In an embodiment, the first fixing member 215 and the second fixing member 216 are, for example, nuts.

In addition, the first insulating gasket 212 is located between the first end surface 211s1 and the first fixing member 215 to electrically isolate the conductive sleeve 211 from the first fixing member 215, so as to prevent the conductive sleeve 211 from being electrically short-circuited through the first fixing member 215. A component of the electric vehicle 200, such as a shock absorber. The second insulating gasket 213 is located between the second end surface 211s2 and the second fixing member 216 to electrically isolate the conductive sleeve 211 from the second fixing member 216. This prevents the conductive sleeve 211 from being electrically short-circuited to the electric through the second fixing member 216. Parts of the car 200, such as a shock absorber. In addition, the inner diameter of the first through hole 211a of the conductive sleeve 211 is larger than the outer diameter of the axle 230, so that the conductive sleeve 211 is separated from the solid material of the axle 230 by the first through hole 211a, so that the electrical sleeve 211 and the axle 230 are electrically avoided. Short circuit.

The axle assembly 205 is detachably assembled to the axle 230 of the electric vehicle 200 through fixing members (such as the first fixing member 215 and the second fixing member 216), thereby having simple assembly and convenient detachability. In the present embodiment, the axle set 205 can be designed to be cylindrical or spherical, such geometry to aid in the locking of any fixture.

As shown in FIG. 3A, the second electrical transmission line 214 is electrically connected to the conductive sleeve 211 and the vehicle end controller 240 to transmit signals and/or power between the conductive sleeve 211 and the vehicle end controller 240.

In step S120, the charging end controller 130 may sense whether the axle assembly 205 of the electric vehicle 200 has entered between the first clamp arm 111 and the second clamp arm 114 of the fixture 110.

For example, please refer to FIG. 4A and FIG. 4B. FIG. 4A is a schematic diagram showing the electric vehicle 200 entering the first clamping arm 111 and the second clamping arm 114 of the fixing device 110, and FIG. 4B is a diagram showing FIG. 4A. A partial top view of the fixture 110 and the electric vehicle 200.

As shown in Figures 4A and 4B, when the electric vehicle 200 is to be charged, the tire 220 of the steerable electric vehicle 200 enters between the two fixtures 110 and 110' and approaches the tire sensor 105. After the tire 220 triggers the tire sensor 105, the axle assembly 205 is shown substantially between the first groove 111r and the second groove 114r. At this time, the charging end controller 130 controls the driving mechanism 115 to rotate to clamp the axle set 205 between the first groove 111r and the second groove 114r. Since the axle set 205 is clamped between the first groove 111r and the second groove 114r, the clamp can be provided and the charging process reliability can be greatly improved.

In step S130, please refer to FIG. 5, which shows a schematic diagram of the fixing device 110 clamping the axle set 205. The charging end controller 130 controls the driving mechanism 115 to rotate to drive the first clamping arm 111 and the second clamping arm 114 to rotate about the first rotating fulcrum 1111 and the second rotating fulcrum 1141, respectively, so that the first groove 111r and the first groove The two grooves 114r are close to each other to clamp the axle set 205 between the first groove 111r and the second groove 114r.

As shown in FIG. 5, the long axis 1151 of the drive mechanism 115 is substantially perpendicular to the first clamp arm 111 and the second clamp arm 114, so that the axle set 205 can be clamped to avoid the axle set 205 being easily and firstly used during charging. The conductive portion 112 is separated. In this way, the clamping lock can be provided and the charging reliability can be greatly improved.

In step S140, the charging end controller 130 can detect whether the first conductive portion 112 and the axle set 205 are electrically connected. For example, please refer to FIG. 6 , which illustrates the first conductive portion 112 of the fixing device 110 , the first conductive portion 112 ′ of the fixing device 110 ′, and the circuit L1 of the charging end controller 130 and the vehicle end controller 240 . . The charging end controller 130 can output a current signal I to the vehicle end controller 240. If the charging end controller 130 receives the current signal I, the first conductive portion 112 and the conductive sleeve 211 of the axle assembly 205 are The contact is made, so that the vehicle end controller 240, the charging end controller 130, the first conductive portion 112 and the first conductive portion 112' form a conductive loop L1. In summary, since the charging system 100 of the embodiment of the present disclosure includes two conductive portions (such as the conductive portions 112 and 112'), a circuit L1 for conducting between the vehicle end controller 240 and the charging end controller 130 can be formed.

Further, one of the first conductive portion 112 of the fixing device 110 and the first conductive portion 112' of the fixing device 110' may be used as a positive electrode, and the other may be used as a negative electrode. In addition, the charging end controller 130 can provide direct current to the electric vehicle 200, but can also provide alternating current to the electric vehicle 200.

In step S150, if the first conductive portion 112 and the axle assembly 205 The conductive sleeve 211 is electrically connected to each other, and the charging end controller 130 detects whether the resistance between the first conductive portion 112 and the conductive sleeve 211 is less than a predetermined resistance value. For example, the charging terminal controller 130 can analyze the current signal I or output a test signal through the loop L1, and calculate the resistance between the first conductive portion 112 and the conductive sleeve 211 by the returned current signal I or the test signal. . If the resistance between the first conductive portion 112 and the conductive sleeve 211 of the axle set 205 is less than the preset resistance, indicating that the charging is normal, the process proceeds to step S160; if not, the charging may be adversely affected by the excessive resistance (eg, The charging system 100 can selectively send a message indicating that "cannot be charged" to the electric vehicle 200 because it cannot be charged, the charging efficiency is poor, and the like.

In step S160, if the resistance between the first conductive portion 112 and the axle set 205 is less than the preset resistance, the charging end controller 130 starts charging the electric vehicle 200 through the axle set 205.

As shown in FIG. 6, the charging end controller 130 can output a carrier signal (not shown) through the loop L1, which can carry both power and signals. In this way, the charging and signal can be transmitted in a single transmission line, and charging and information exchange can be performed simultaneously. Further, since the charging end controller 130 can output a carrier signal, the connection between the vehicle end controller 240, the charging end controller 130, the first conductive portion 112 and the first conductive portion 112' can be connected by a single transmission line. In another embodiment, the signal can be transmitted between the charging end controller 130 and the vehicle end controller 240 in a wireless manner.

In summary, after the electric vehicle 200 enters the fixture 110, the charging system 100 can control the fixture 110 to automatically clamp the electric vehicle, automatically charge, and release according to the indication. For example, after the charging system receives the user rental instruction, The electric car can be automatically released, but not limited to this.
