Detailed Description

Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

The charging module 100 of the embodiment of the present utility model is used for electrically connecting with the power receiving module 200, for example, the charging module 100 may be mounted on a fixed device like a charging post, and the power receiving module 200 may be mounted on a movable mobile device like a robot.

When in use, the charging module 100 and the power receiving module 200 can be mutually close, and the electrical connection of the charging module 100 and the power receiving module 200 can be realized through the contact of the charging module 100 and the power receiving module 200, so that the use requirement of charging can be met. After the charging is completed, the charging module 100 and the power receiving module 200 may be separated, so that the electrical connection of the two may be cut off.

As shown in fig. 1, a charging module 100 according to an embodiment of the present utility model includes a mounting base 11, a pole 12 and a trigger 13. Wherein mount pad 11 can be columnar structure, can be equipped with the installation cavity in the mount pad 11, and the installation cavity can be along fore-and-aft direction extension, and the front end of installation cavity can be open, and the front end of installation cavity is equipped with the opening with outside intercommunication promptly.

The pole 12 is slidably mounted on the mounting seat 11, the pole 12 is used for electrically contacting with the power receiving module 200, and the pole 12 slides relative to the mounting seat 11 through the stopping of the power receiving module 200. For example, the pole 12 may be cylindrical, the pole 12 may be slidably fitted in the mounting cavity, and the pole 12 may be slidably moved in the front-rear direction with respect to the mount 11. In use, the pole 12 may be first contacted with the power receiving module 200, and then the pole 12 may be driven to slide in the mounting cavity by moving the power receiving module 200.

It should be noted that, when the withstand voltage of the power receiving module 200 is not received, the pole 12 has a self-resetting function, for example, the pole 12 may be reset by a spring, a rubber, or other elastic component, so as to meet the requirement of repeated use.

The trigger 13 performs a trigger operation by sliding the pole 12 or sensing with the power receiving module 200, and the trigger operation is used to perform cutting off or conducting of a circuit between the pole 12 and the power receiving module 200.

As shown in fig. 1, the trigger 13 may be mounted on the mounting base 11, and in use, the triggering operation of the trigger 13 may be achieved by using the sliding motion of the pole 12. In other embodiments, as shown in fig. 2, the trigger 13 may not be disposed on the mounting base 11, that is, the trigger 13 may be independent of the mounting base 11, and in this case, the trigger 13 may perform the triggering operation through sensing a distance from the power receiving module 200.

It should be noted that, the triggering operation of the triggering member 13 has two forms, namely a circuit-breaking form and a circuit-conducting form, and the process and the return of the pole 12 or the power receiving module 200 can respectively correspond to the triggering operation of circuit conduction and the triggering operation of circuit breaking, thereby also meeting the requirement of repeated use.

When the power receiving module 200 is charged, the triggering operation lags behind the contact of the pole 12 and the power receiving module 200, and the circuit is conducted after both the electrical contact and the triggering operation are performed by the pole 12 and the power receiving module 200.

Specifically, during charging, the power receiving module 200 and the charging module 100 may be close to each other, at this time, the pole 12 and the power receiving module 200 may be contacted first, then the triggering operation of the triggering member 13 is performed, and after the circuit is conducted by the triggering member 13, the current will flow between the pole 12 and the power receiving module 200. Therefore, the situation that the pole 12 and the power receiving module 200 are hot plugged in and out during contact can be avoided, and live contact operation is avoided.

When the power receiving module 200 is powered off, the triggering operation is performed before the contact between the pole 12 and the power receiving module 200 is released, and the circuit between the pole 12 and the power receiving module is cut off after the triggering operation.

Specifically, when the power is off, the power receiving module 200 and the charging module 100 may be separated from each other, and in this process, the triggering operation of the triggering member 13 performs the triggering operation of circuit breaking first, and then the contact between the pole 12 and the power receiving module 200 is released. After the trigger 13 performs the triggering operation of circuit breaking, the current between the pole 12 and the power receiving module 200 is broken, i.e., no current passes between the pole 12 and the power receiving module 200. Therefore, the situation that the pole 12 and the power receiving module 200 are hot plugged during separation can be avoided, and live working is avoided.

The charging module provided by the embodiment of the utility model can avoid the problem of hot plug during use or operation, so that the condition of electric spark is avoided, the condition of battery damage and pole piece oxidation is avoided, and the service life of charging structures such as a charging pile is prolonged.

In some embodiments, there are a plurality of triggering pieces 13, and triggering operations of the plurality of triggering pieces 13 do not proceed simultaneously. For example, as shown in fig. 2, two triggering pieces 13 may be provided, and both triggering pieces 13 may perform triggering operations, specifically, in the charging process, after the pole 12 and the power receiving module 200 are in contact, the two triggering pieces 13 may sequentially perform triggering operations of circuit conduction, and after both triggering pieces 13 perform triggering operations of circuit conduction, a circuit is conducted between the pole 12 and the power receiving module 200 and a current flows.

In the power-off process, the two triggering pieces 13 can sequentially perform the triggering operation of circuit breaking, and after the triggering operation is completed by the two triggering pieces 13, the contact separation can be performed between the pole 12 and the power receiving module 200.

It will be appreciated that in other embodiments, the trigger 13 may be provided with three, four, five, etc. of the plurality of trigger operations, so as to provide better circuit protection.

In some embodiments, when the trigger 13 is provided with a plurality of triggers, the form of the trigger operations generated by the plurality of triggers 13 may also be different, for example, when there are two triggers 13, one trigger operation may be implemented by the sliding action of the pole 12, and the other trigger operation may be implemented by sensing with the power receiving module 200.

Specifically, as shown in fig. 2, the plurality of triggering pieces 13 includes a first triggering piece 131 and a second triggering piece 132. The first trigger member 131 is disposed on the mounting seat 11, and the first trigger member 131 performs a triggering operation by contacting with the pole 12 or by sliding and stopping of the pole 12. The second triggering member 132 is independent from the mounting seat 11, and the second triggering member 132 achieves triggering operation through sensing with the power receiving module 200. The protective effect can be further enhanced by means of this different trigger form.

In some embodiments, the first trigger 131 is a contact, the first trigger 131 enables circuit conduction through contact with the pole 12, and the first trigger 131 enables circuit disconnection through separation from the pole 12.

For example, the contact may be an electrical connector such as a spring, and the first trigger member 131 may be disposed at the rear end of the pole 12. When the power receiving module 200 is used, the power receiving module 200 can act on the front end of the pole 12, and when the power receiving module 200 pushes the pole 12 backwards, the rear end of the pole 12 can be contacted with the first trigger piece 131, so that the triggering operation of circuit conduction between the first trigger piece 131 and the pole 12 can be realized.

When the pole 12 loses the withstand function of the power receiving module 200, the pole 12 can reset by itself, and at this time, the pole 12 and the first trigger 131 can realize contact separation, so that the triggering operation of circuit breaking between the first trigger 131 and the pole 12 can be realized.

In some embodiments, the first trigger 131 is a switch, and the first trigger 131 is turned on or off by sliding the pole 12 to trigger the triggering operation.

For example, the first trigger 131 may be a switch such as a travel switch, and the first trigger 131 may be provided at the rear end of the pole 12. When the power receiving module 200 is used, the front end of the pole 12 can be acted on, the pole 12 can move backwards under the action of the power receiving module 200, the switch can be pushed by the pole 12, and under the pushing action of the pole 12, the switch can realize circuit closing, so that the triggering operation of circuit conduction can be completed.

When the pole 12 loses the withstand function of the power receiving module 200, the pole 12 will reset forward by itself, and at this time, the switch can realize circuit cutting under the action of forward sliding of the pole 12, so as to complete the triggering operation of circuit cutting.

In some embodiments, the second triggering element 132 is a hall sensor, which is used to sense with the magnet 23 on the power receiving module 200 to implement the triggering operation. Specifically, when in use, the power receiving module 200 can be close to the charging module 100, when the power receiving module is close to a certain distance, the hall sensor can sense the magnetic field of the magnet 23 on the power receiving module 200, and then a corresponding sensing signal can be generated, and the triggering operation of circuit conduction can be realized by means of the sensing signal.

When the power receiving module 200 and the charging module 100 are far away from each other, when the distance between the power receiving module 200 and the charging module 100 is greater than a certain range, the hall sensor also generates a corresponding sensing signal, and the triggering operation of circuit breaking can be realized by means of the sensing signal.

In some embodiments, the charging module 100 includes a reset member disposed on the mounting base 11 and acting between the mounting base 11 and the pole 12, and the reset member is configured to apply a reset force to the pole 12 so that the pole 12 has a tendency to be released from the first trigger 131.

Specifically, the restoring member may be an elastic member such as a spring, and the restoring member may be assembled in the installation cavity of the installation seat 11, and the restoring member may be sleeved on the outer circumferential side of the pole 12, the front end of the restoring member may be abutted against the pole 12, the rear end of the restoring member may be abutted against the installation seat 11, and when the pole 12 moves towards the direction of the first triggering member 131, the restoring member may be compressed and store energy, so that the restoring member may automatically restore under the action of the restoring member when the pole 12 is released from the compression of the power receiving module 200, thereby meeting the requirement of repeated use.

In some embodiments, as shown in fig. 2, the first triggering member 131, the mounting seat 11, and the pole 12 form conductive units, two conductive units, and two conductive units are respectively a positive conductive unit and a negative conductive unit, wherein the positive conductive unit may be located on the right side of the negative conductive unit, and the second triggering member 132 is disposed between the two conductive units.

When in use, the first triggering piece 131 and the pole 12 of the two conductive units can synchronously act, thereby meeting the use requirement of the electric contact of the anode and the cathode. The second triggering member 132 is independent of the two conductive units, and is capable of automatically completing the triggering operation with the power receiving module 200 in an inductive manner.

It should be noted that, since the first triggering members 131 of the two conductive units are connected in series with the corresponding pole 12, when the circuit between the first triggering frame of one conductive unit and the corresponding pole 12 is cut off due to the skew of the subsequent self-moving device during the charging process, no current passes between the power receiving module 200 and the charging module 100, thereby further avoiding the hot plug phenomenon and further improving the safety and the electrical protection of the operation.

The self-mobile device of the embodiment of the present utility model is described below.

The self-moving device can be a production line robot, a cleaning robot, a surgical robot, a meal delivery robot, a hotel delivery robot and other types of robots, and can be other types of devices with self-moving capability.

The self-mobile device according to the embodiment of the present utility model includes a power receiving module 200, where the power receiving module 200 is configured to contact the pole 12 of the charging module 100, as shown in fig. 3, and the power receiving module 200 includes a housing 21, a pole piece 22 and a magnet 23. The housing 21 may be rectangular plate-shaped, and the longitudinal direction of the housing 21 may be the left-right direction.

The pole piece 22 is an electrode piece 22, and the pole piece 22 is disposed on the housing 21, for example, the pole piece 22 may be fixed on the housing 21 by a fastening manner. In use, the power receiving module 200 and the charging module 100 are electrically connected by the pole piece 22 coming into contact with the pole 12.

The magnet 23 is a permanent magnet, and the magnet 23 is provided on the housing 21, for example, an assembly groove may be provided on the housing 21, and the magnet 23 may be embedded in the assembly groove. When the power receiving module 200 and the charging module 100 are close to each other, the magnet 23 may be disposed opposite to the second triggering member 132, and the second triggering member 132 may generate induction by the magnetic field of the magnet 23, so as to complete the corresponding triggering action.

In some embodiments, as shown in fig. 3, there are two pole pieces 22, and the two pole pieces 22 are a positive pole piece and a negative pole piece, respectively, which may be arranged at intervals in the left-right direction, and the magnet 23 may be disposed between the positive pole piece and the negative pole piece. When the positive electrode plate is used, the positive electrode plate is used for being in abutting contact with the pole 12 of the positive electrode conductive unit, and the negative electrode plate is used for being in abutting contact with the pole 12 of the negative electrode conductive unit. So that the positive and negative electrodes of the charging module 100 and the power receiving module 200 can be electrically connected.

In some embodiments, the mounting base 11 is magnetically conductive, so that a magnetic attraction effect can be generated between the mounting base 11 and the magnet 23, so that a contact force between the power receiving module 200 and the charging module 100 can be increased, poor contact between the power receiving module 200 and the charging module 100 is avoided, and further, the problems of sliding and the like can be avoided.

The charging method according to the embodiment of the present utility model is described below.

The charging method according to the embodiment of the present utility model is implemented based on the charging module 100 as in the above embodiment and the self-mobile device as in the above embodiment, and the charging method may include the steps of:

A1: the power receiving module 200 is moved in a direction approaching the charging module 100 so that the pole 12 is in contact with the power receiving module 200. For example, as shown in fig. 4, the charging module 100 may remain stationary, and the power receiving module 200 may be located at the front side of the charging module 100. When in use, the power receiving module 200 can be moved backwards until the two pole pieces 22 (positive pole piece and negative pole piece) on the power receiving module 200 are respectively in contact with the front ends of the two pole posts 12 (positive pole post and negative pole post) on the charging module 100.

A2: the power receiving module 200 is continuously moved towards the direction approaching the charging module 100 until the triggering pieces 13 sequentially realize the triggering operation of circuit conduction. For example, two triggering pieces 13 may be provided, and the two triggering pieces 13 may be the first triggering piece 131 and the second triggering piece 132 described above, respectively. After the pole 12 contacts with the pole piece 22, the power receiving module 200 can be continuously moved backward, and under the action of the power receiving module 200, the two pole 12 on the charging module 100 can synchronously slide backward relative to the corresponding mounting seat 11, so that the triggering operation of conducting the circuits of the first triggering piece 131 of the positive electrode conductive unit and the negative electrode conductive unit can be respectively realized, as shown in fig. 5.

Then, the power receiving module 200 may be moved backwards continuously, and when the second trigger 132 on the charging module 100 approaches to a certain distance, the second trigger 132 senses the magnetic field of the magnet 23 on the power receiving module 200 and generates a sensing signal, and under the action of the sensing signal, the triggering operation of the circuit conduction of the second trigger 132 may be realized, as shown in fig. 6.

A3: the circuit between the pole 12 and the power receiving module 200 is completed. Specifically, after all the triggering pieces 13 complete the triggering operation of corresponding circuit conduction, circuit conduction can be formed between the positive pole and the positive pole piece, and between the negative pole and the negative pole piece, and current can pass through the circuit conduction, so that the use requirement of charging the self-mobile device provided with the power receiving module 200 by the charging module 100 is met.

The power-off method of the embodiment of the present utility model is described below.

The power-off method according to the embodiment of the present utility model is implemented based on the charging module in the above embodiment and the self-mobile device in the above embodiment, and the power-off method may include the following steps:

B1: the power receiving module 200 is moved away from the charging module 100 until a trigger 13 achieves a trigger operation of circuit breaking. For example, two triggering pieces 13 may be provided, and the two triggering pieces 13 are the first triggering piece 131 and the second triggering piece 132 described above, respectively. As shown in fig. 6, when power is required to be removed, the power receiving module 200 may be moved forward, and at this time, the second trigger 132 may be triggered by the power-off of the power generating circuit due to the relative position change of the magnet 23 and the second trigger 132.

B2: the circuit between the pole 12 and the power receiving module 200 is cut off. After the second trigger 132 performs the triggering operation of circuit breaking, the circuit between the positive electrode post and the positive electrode tab and between the negative electrode post and the negative electrode tab is broken, i.e., no current passes between the two electrode posts 12 and the two electrode tabs 22.

B3: the power receiving module 200 is continuously moved away from the charging module 100 until the remaining trigger 13 achieves the triggering operation of circuit breaking. For example, after the second trigger 132 performs the triggering operation of circuit breaking, the power receiving module 200 may be moved forward continuously, and at this time, the two poles 12 may be reset forward by themselves under the action of the corresponding reset element, so that the triggering operation of circuit breaking of the first trigger 131 of the two conductive units may be completed respectively, as shown in fig. 5.

It should be noted that, in other embodiments, during the process of the power receiving module 200 being away from the charging module 100, the triggering operation of circuit breaking of the first triggering member 131 may be performed first, and then the triggering operation of circuit breaking of the second triggering member 132 may be performed, that is, when the plurality of triggering members 13 are provided, the sequence of the triggering operations of circuit breaking of the plurality of triggering members 13 may be adaptively adjusted and changed.

B4: the power receiving module 200 is continuously moved in a direction away from the charging module 100 until the pole 12 and the power receiving module 200 are separated. For example, as shown in fig. 4, after the first trigger 131 and the second trigger 132 perform the triggering operations of cutting off the corresponding circuits, the power receiving module 200 may be moved forward, and when the moving distance of the power receiving module 200 exceeds the reset stroke of the pole 12, the two pole pieces 22 on the power receiving module 200 are separated from the two pole pieces 12 on the charging module 100.

A specific example of the present utility model is described below.

The magnet arranged on the power receiving module 200 interacts with the mounting seat 11 made of metal material on the charging module 100, so that the contact force between the power receiving module 200 and the charging module 100 can be increased, poor contact is avoided, and meanwhile, a certain effect of preventing a car from sliding is achieved.

The travel switch is arranged behind the positive and negative poles of the power receiving module 200, so that the contact between the lower negative pole piece and the positive and negative poles can be fully ensured, and then the travel switch is conducted to charge, thereby preventing hot plug and further preventing the generation of electric spark.

The hall sensor (second trigger 132) is a safety mechanism, and charging can be started only when the positive and negative electrodes are in contact, and three conditions of travel switch conduction and hall sensor conduction are triggered. Therefore, safety accidents caused by the fact that the charging pile is mistakenly touched by people on the positive and negative plates in public places can be prevented.

During charging, the power receiving module 200 approaches the charging module 100 slowly, as shown in fig. 4, the power receiving electrode plate 22 on the power receiving module 200 is already in contact with the positive and negative poles on the charging module 100, and the travel switch and the hall are not triggered at this time.

The power receiving module 200 continues to approach the charging module 100 slowly until the positive and negative poles of the power receiving module 200 contact the travel switch, as shown in fig. 5.

The power receiving module 200 continues to approach the charging module 100 slowly, and finally the hall sensor is triggered, as shown in fig. 6, and charging is started at this time.

The sequence of triggering charging is: the 1 positive and negative electrode contact- (2) travel switch conduction- (3) Hall sensor conduction.

After the charging is finished, the power receiving module 200 moves forwards slowly, firstly, the Hall sensor is disconnected, then the travel switch is disconnected, and finally, the positive and negative plates are disconnected, so that hot drawing operation cannot occur, electric sparks are prevented, and the service lives of the power receiving plate 22 and the charging post 12 are prolonged.

The sequence of disconnecting the charging is: 1 hall sensor off-2 travel switch off-2 positive and negative electrode off

Of course, the turn-on and turn-off sequences of the travel switch and the hall sensor and the travel switch may be reversed, which reduces the matching conditions for the selection of the travel switch and the hall sensor.
