Description

Charging stand for automatic charging of mobile vehicles and its applicable charging system

The present invention relates to a charging stand, and more particularly to a charging stand that can be automatically charged by a mobile vehicle and that can be combined with the mobile carrier at any horizontal angle and its applicable charging system.

Mobile vehicles, such as mobile robots or sweeping robots, are set to automatically travel within a certain range to complete a given task, and in order to make the mobile vehicle have a higher degree of freedom of movement, usually in mobile vehicles. The internal configuration of the rechargeable battery is used as the main power source to avoid the constraint of the cable. In addition, due to the limited power of the rechargeable battery, the mobile carrier will be used with a charging stand, when the mobile carrier operates for a period of time. The time or the power of the rechargeable battery is lower than a specific value, and the mobile vehicle searches for the position of the charging stand to move to the charging stand to interface with the charging stand, thereby automatically charging the rechargeable battery.

Please refer to FIG. 1 , which is a schematic diagram of a conventional charging system. As shown in FIG. 1 , the conventional charging system 1 is composed of a charging stand 10 and a mobile carrier 11 , wherein the charging stand 10 has a bottom 100 , an inner side 101 , an outer side 102 , and a top 103 , wherein the inner side 101 and The outer side surface 102 is oppositely disposed on the outer wall of the charging base 10, and the bottom 100 extends outwardly from one end of the inner side surface 101 and is perpendicular to the inner side surface 101. The charging stand 10 further has a first negative electrode 104, a first positive electrode 105 and a wireless signal transmitter 106. The first negative electrode 104 is disposed on the bottom 100, and the first positive electrode 105 is corresponding to the first negative electrode 104. The wireless signal transmitter 106 is disposed on the top surface 101, and the wireless signal transmitter 106 is disposed on the top portion 103 to emit a wireless signal having a specific emission range in a direction facing the inner side surface 101. The mobile carrier 11 has a second negative electrode 110, a second positive electrode 111, and a wireless signal receiver 112. When the mobile carrier 11 is to be charged in combination with the charging stand 10, it is received by wireless signals while moving. The device 112 searches for the wireless signal transmitted by the wireless signal transmitter 106. After the mobile carrier 11 moves to the wireless signal range transmitted by the wireless signal transmitter 106 and the wireless signal receiver 112 receives the wireless signal, the wireless signal is transmitted by the wireless signal. Judging the position of the charging stand 10, the mobile carrier 11 is automatically moved and adjusting the moving position to approach the charging stand 10, and when the mobile carrier 11 moves to the charging stand 10, the second negative of the mobile carrier 11 The electrode 110 and the second positive electrode 111 can be in contact with the first negative electrode 104 and the first positive electrode 105, respectively, thereby causing the charging stand 10 to charge the mobile carrier 11.

Although the conventional charging system 1 can achieve the purpose of automatically charging the mobile carrier 11, the position of the first negative electrode 104 and the first positive electrode 105 of the charging stand 10 on the charging stand 10 is limited to the inner side. 101 and the bottom 100, and the wireless signal transmitter 106 transmits only a specific range of wireless signals in the direction in which the inner side 101 faces, so when the mobile carrier 11 is to be combined with the charging stand 10 for charging, the mobile vehicle 11 can move only to the charging stand 10 with a specific range and angle, so that the first negative electrode 104 and the first positive electrode 105 can be connected to the second negative electrode 110 and the second positive electrode 111, respectively, to perform charging operation, so it is easy because The error of the moving position causes the first negative electrode 104 and the first positive electrode 105 not to interface with the second negative electrode 110 and the second positive electrode 111. If the charging fails, if the probability of successful charging is to be increased, it is necessary to utilize more complicated algorithms and circuits, which also leads to an increase in the production cost of the charging system 1.

Moreover, since the wireless signal transmitted by the wireless signal transmitter 106 of the charging stand 10 has a specific range, when the mobile carrier 11 is to be automatically charged, if the mobile carrier 11 is adjacent to the charging stand 10, When the wireless signal receiver 112 is still unable to receive the wireless signal within the specific range of the wireless signal transmitted by the wireless signal transmitter 106, the mobile carrier 11 can only search for the wireless signal by continuously moving, thus Therefore, it takes a long time for the mobile carrier 11 to successfully connect to the charging stand 10 for charging work.

In view of this, how to develop a charging stand for the automatic charging of the mobile vehicle and the applicable charging system which can improve the above-mentioned conventional technology is an urgent problem to be solved.

Guided, so that the effect of greatly improving the success of charging can be achieved without using complex algorithms and circuit structures, so that the mobile carrier of the conventional charging system can only move toward the charging stand with a specific range and angle. The first negative electrode and the first positive electrode of the charging base can be respectively connected to the second negative electrode and the second positive electrode of the mobile carrier to perform charging operation, resulting in a lack of successful charging.

Another object of the present invention is to provide a charging stand for automatic charging of a mobile vehicle and a charging system therefor, which use the infrared emitting device of the charging stand to emit a 360-degree infrared array signal, so that the charging stand can be placed freely.
