Technical Field

The present disclosure relates to a charger for a wearable device, and more particularly, to a charging head capable of preventing a short circuit and a charged device.

Background

With the development of society and the living standard of people, the requirements of people on medical treatment and nursing level are increasing, and especially the requirements of the aging population on the detection of daily physiological indexes are more comprehensive. Therefore, with the development of electronic technology, medical detection apparatuses are increasingly miniaturized and portable, so that detection services of real-time physiological indexes can be provided for various users.

At present, in the field of medical care, pulse oximeters are increasingly widely used as equipment for monitoring indexes such as human body blood oxygen saturation, pulse rate and the like, and portable pulse oximeters are increasingly adopted in the aspect of monitoring real-time blood oxygen indexes of patients, so that timely charging of the pulse oximeters is also becoming more urgent. When a rechargeable battery is used as an economical and environment-friendly way to supply energy for a pulse oximeter, a corresponding charging seat is essentially needed. However, the charging stand is generally inconvenient, and the portable wearable device as the charged device is generally formed in a recess form in order to reduce the external size, which makes the charging device generally exposed. But such an exposed charging head is liable to cause a short circuit when it is in contact with other external electrical conductors. Therefore, people need to provide a short-circuit-preventing charging head, which can be convenient for directly contacting and charging charged equipment, and is free from troublesome operation caused by shielding protection of the charging head by adding a cap.

In order that those skilled in the art will better understand the present disclosure, the present disclosure will be described in further detail below with reference to the accompanying drawings and detailed description.

Shown in fig. 1 is a schematic diagram of an anti-short circuit charging head 10 according to the present disclosure. Fig. 2 is a schematic diagram of a charged device 20 using a short circuit prevention charging head according to the present disclosure. As shown in fig. 1, the short-circuit prevention charging head 10 includes a charging coupling plane 11. The coupling plane 11 corresponds to the coupling plane 21 of the charged device 20. Three projections 22 arranged in a triangle on the charge coupling plane 11. The triangular arrangement may allow the charging head to be in a stable state when placed on a certain platform. The stud 12 protrudes a first height above the charge coupling plane 11. At the interval of the connection lines of the first and second and third posts 12, 12 of the three posts 12, an elastic contact 13 is provided, the elastic contact 13 protrudes from the charge coupling plane 11 by a second height, which is smaller than the first height. Therefore, when the three projections 12 are in contact with another plane (not shown), the elastic contact 13 cannot be simultaneously in contact with the other plane, so that in the non-charged state, the short circuit of the elastic contact 13 in the case where the other plane is a conductor is avoided.

As shown in fig. 2, the charged device 20 used in cooperation with the short-circuit prevention charging head 10 shown in fig. 1 includes a charging coupling plane 21 corresponding to the charging coupling plane 11. Three grooves 22 arranged in a triangle on the charge coupling plane 21, wherein the bottoms of the grooves 22 are lower than the charge coupling plane by a third height, and the third height is larger than or equal to the first height. At the interval of the connecting lines of the first groove 22 and the second groove 22 and the third groove 22 among the three grooves 22, a charging contact 23 is provided. The charging contact 23 protrudes from the charging coupling plane, so that the charged device 20 and the short-circuit preventing charging head 20 are fixed to each other when the three bosses 12 corresponding to the three grooves 22 on the short-circuit preventing charging head 10 are inserted into the three grooves 22. In this way, the elastic contact 13 of the short-circuit prevention charging head 10 is pressed against the corresponding charging contact 23 on the charged device 20 to perform charging.

Fig. 3 is a schematic view showing the short-circuit prevention charging head 10 according to the present disclosure in a separated state from the charged device 20. Wherein the curved dashed lines represent the corresponding states between the respective components of the short-circuit preventing charging head 10 and the charged device 20. As shown in fig. 3, when the user is charging the charged device 20, if the short-circuit prevention charging head 10 is disposed in a staggered manner with respect to the charged device 20, the boss 12 of the short-circuit prevention charging head 10 will not be inserted into the recess 22 of the charged device 20, and thus charging cannot be performed or erroneous contact is caused to cause destruction of the charged device. This is a safety protection for the elderly or for less careful users.

Fig. 4 is a perspective view of a combination 20 of a short circuit prevention charging head 10 and a charged device according to the present disclosure. The combination of the two corresponds to the operation performed in a dotted line manner shown in fig. 3.

Referring back to fig. 1 and 2, as described above, the projections 12 correspond to the three grooves 22 arranged on the charging coupling plane 21 on the charged device 20, so that when the short-circuit preventing charging head 10 charges the charged device 20, the projections 12 are inserted into the three grooves 22, thereby fixing the charged device 20 and the short-circuit preventing charging head 10 to each other, and bringing the elastic contact 13 of the short-circuit preventing charging head 10 into pressing contact with the corresponding charging contact 23 on the charged device 20 for charging. Preferably, the boss 12 may be made of an elastic material, so that it may be conveniently inserted into the recess 22 in an interference fit manner, so that the short-circuit prevention charging head 10 and the charged device 20 are not easily detached after being coupled to each other.

It should be noted that the cross-section of the stud 12 has one of a circular shape, a polygonal shape and an elliptical shape. The corresponding recess 22 is also one of a corresponding circle, polygon and ellipse so that the two match.

Further, on the back surface of the short-circuit prevention charging head 10 opposite to the charging coupling plane 11, a charging indicator lamp (not shown) is provided, which is lighted when the elastic contact 13 of the short-circuit prevention charging head 10 is in pressing contact with the corresponding charging contact 23 on the charged device 20.

In summary, according to the short-circuit prevention charging head 10 of the present disclosure, by the triangular layout design of the protruding columns, on one hand, the short circuit of the charging head in the empty state is prevented, on the other hand, the situation that the charged device cannot be charged or damaged due to carelessness or wrong charging adaptation of the old is prevented, and further, the charged device and the short-circuit prevention charging head are firmly connected in the charging process.
