Description

Charging device

Technical Field

The present invention relates to a charging device, and more particularly to a charging device having a filler, a first through hole and a second through hole, which utilizes the filler, the first through hole and the second through hole to discharge water.

Background

Electronic devices have been developed toward miniaturization and portability, and more electronic devices are designed as portable devices without plug connection. However, the electronic device with such a portable design usually needs to be powered by a battery, and when the battery capacity is insufficient, a user must charge the electronic device (for example, charge a charging seat). When the electronic device is operated in a normal temperature environment, the electronic device and the charging stand can be normally charged. However, when the electronic device is in a low temperature environment and the charging dock is disposed in a normal temperature environment, the electronic device transfers from the low temperature environment to the normal temperature environment to form a temperature difference, the relatively low temperature surface of the electronic device gradually condenses the moisture into water drops, and the water drops flow to the charging dock along the surface of the electronic device. During the charging process of the charging seat, the electroplated layer of the charging seat terminal can be electrolyzed due to moisture or water drops, so that the metal oxidation phenomenon is accelerated, and the charging failure or abnormity of the charging seat terminal is caused.

Detailed Description

Please refer to fig. 1, fig. 2 and fig. 3. Fig. 1 is a perspective view of a charging device according to some embodiments of the present invention. Fig. 2 isbase:Sub>A cross-sectional view in the directionbase:Sub>A-base:Sub>A of fig. 1. Fig. 3 is a front view of an electronic device connected to a charging device according to some embodiments of the present invention. As shown in fig. 1 to 3, the charging device 10 includes a base 102, a charging assembly 104 and a filling member 106. The base 102 includes a charging slot 110 and a receiving slot 112. The charging slot 110 has a first opening 114 and a second opening 116. The first opening 114 has a first through hole 118, the receiving cavity 112 has a second through hole 120, and the first through hole 118 is connected to the second through hole 120. The charging assembly 104 is connected to the second opening 116. The filling member 106 is connected to the inner side of the first opening 114 and adjacent to the first through hole 118, and the filling member 106 has a connection port 107. The inner side of the first opening 114 has a first distance, and the inner side of the connection port 107 has a second distance, and the first distance is greater than the second distance (described later in fig. 5).

In some embodiments, the first through aperture 118 may be in communication with a second through aperture 120 (described below) via a drain assembly 108.

As shown in fig. 2 and fig. 3, the charging device 10 can charge an electronic device 20, and when the electronic device 20 moves from a low temperature environment to a normal temperature environment, a water droplet (or water vapor) is generated on the surface of the electronic device 20 due to the environmental temperature change on the surface of the electronic device 20, the charging device 10 can eliminate the water droplet of the electronic device 20 dropping on the charging device 10, and prevent the water droplet from flowing into the charging slot 110, so that during the charging process of the charging device 10, an electroplating layer on the surface of the charging element 104 and the surface of a charging portion 201 of the electronic device 20 is prevented from being electrolyzed, which causes an accelerated metal oxidation phenomenon and causes charging failure of the charging element 104 and the charging portion 201. In some embodiments, the charging device 10 may be electrically connected to a power source (e.g., the mains power or a power source provided by a power supply) to power the charging assembly 104 and the related circuit modules (described later). The electronic device 20 may be, for example, but not limited to, a mobile phone, a handheld barcode scanner, or a handheld computer.

As shown in fig. 2 and 3, the base 102 is used for connecting and supporting the electronic device 20. When the electronic device 20 is connected to the base 102, the charging portion 201 of the electronic device 20 can be coupled to the charging element 104 in the charging slot 110, so that the charging element 104 can charge the electronic device 20. The receiving groove 112 of the base 102 can receive the charging assembly 104 or a related circuit module (e.g., a circuit board composed of a rectifying circuit, a transforming circuit and a control circuit). In some embodiments, the charging slot 110 and the receiving slot 112 may be integrally formed, or the charging slot 110 and the receiving slot 112 may be connected to each other. In some embodiments, as shown in fig. 2, the charging assembly 104 has a plumb line L1, wherein the plumb line L1 may be an axis extending from the center of the charging assembly 104 in the Z-axis direction in fig. 2. The first opening 114 of the charging slot 110 faces the second opening 116, which may mean that the center of the first opening 114 and the center of the second opening 116 are substantially located on the plumb line L1. It may also mean that the second opening 116 is visible from the first opening 114. When the electronic device 20 enters the charging slot 110 through the first opening 114 and the connection port 107, the electronic device 20 can be coupled to the charging element 104 of the second opening 116 along a trajectory of the plumb line L1 (e.g., a negative Z-axis direction in fig. 2).

As shown in fig. 2 and 3, the charging assembly 104 is connected to the second opening 116 for charging the electronic device 20. In some embodiments, the charging assembly 104 has a charging connection 122, and the charging connection 122 can be matched with the charging portion 201 of the electronic device 20. The charging connection portion 122 is matched with the charging portion 201, which may mean that the charging assembly 104 is electrically connected to the electronic device 20, so that the charging assembly 104 charges the electronic device 20. In some embodiments, the charging connection portion 122 may be a connection terminal, an electrode pad or a wireless charging module, but the charging connection portion 122 may be coupled to the charging portion 201 of the electronic device 20, so that the charging assembly 104 charges the electronic device 20, which is not limited to the connection terminal, the electrode pad or the wireless charging module. Taking the connection terminal as an example, in fig. 2, the charging connection portion 122 has at least one connection terminal 124, and the charging portion 201 of the electronic device 20 is a charging hole. When the electronic device 20 is connected to the housing 102, the connection terminal 124 may be coupled to the charging portion 201 (charging hole) to form an electrically conductive state. In some embodiments, the charging component 104 may integrate the aforementioned circuit modules (e.g., a rectifying circuit, a transforming circuit or a control circuit), or the charging component 104 and the circuit modules may be independent from each other and electrically connected to the charging component 104 and the circuit modules through a connection line. In some embodiments, the connection terminal 124 is parallel to the plumb line L1, whereby the charging portion 201 is coupled to the connection terminal 124 substantially along the plumb line L1 after the electronic device 20 enters the charging slot 110 through the first opening 114.

As shown in fig. 2, the filling member 106 can be attached to the inner side of the first opening 114 by means of adhesive or embedding. The filling member 106 is elastic, and the material thereof can be, for example, but not limited to, a rubber, an elastic plastic or a silicone. The filling member 106 may correspond to the shape of the first opening 114 and be embedded in the first opening 114 (described later), for example, the filling member 106 and the first opening 114 may have the same shape, and the filling member 106 may also be made of an elastic material to match the shape of the first opening 114 and be fixed to the first opening 114. In some embodiments, the filler 106 may be parallel or non-parallel to the first opening 114. As shown in fig. 2, taking the filling member 106 as an example parallel to the first opening 114, the first through hole 118 extends along the X-axis direction in fig. 2 to form a horizontal line L2, and the filling member 106 extends along the X-axis direction in fig. 2 to form an axis L3, wherein the axis L3 is parallel to the horizontal line L2. Accordingly, when the electronic device 20 is connected to the base 102, the filling member 106 and the electronic device 20 can be in a perpendicular relationship with each other. In some embodiments, the connection port 107 of the filler 106 may be, for example, a slit. The connection port 107 can be opened by an external force, when the electronic device 20 passes through the filling member 106 from the connection port 107, the filling member 106 can tightly cover the electronic device 20, and the electronic device 20 is embedded in and exposed out of the charging slot 110 (as shown in fig. 2) according to the position where the filling member 106 tightly covers the electronic device 20. Wherein the horizontal line L2 may be located between an inlet and an outlet of the first through aperture 118 (described later with reference to fig. 6), and the axis L3 may be located at the top of the filling member 106.

As shown in fig. 2, in some embodiments, the charging slot 110 has an assembly groove 126 inside, the assembly groove 126 is adjacent to the first through hole 118, and the filling member 106 is assembled in the assembly groove 126 and protrudes out of the assembly groove 126. In some embodiments, the filling member 106 includes a fixing portion 127 (shown in fig. 2 as a dotted line of the filling member 106), and the fixing portion 127 can be embedded in the assembling recess 126, so that the filling member 106 is fixed in the assembling recess 126. The thickness of the fixing portion 127 (the thickness is the length of the fixing portion 127 along the Z-axis in fig. 2) may be greater than or equal to an insertion length of the assembling groove 126 (the insertion length is the length of the opening of the assembling groove 126 along the Z-axis in fig. 2). For example, when the fixing portion 127 is assembled in the assembling recess 126, the fixing portion 127 can compress its volume to match the size of the assembling recess 126, so that the fixing portion 127 enters and is fixed in the assembling recess 126. The fixing portion 127 may also be adhered to the assembling recess 126 after coating a bonding glue.

As shown in fig. 2, the drainage member 108 connects the first through hole 118 and the second through hole 120, such that the first through hole 118 is in communication with the second through hole 120. The first through hole 118 may be a hole, a slit or an opening penetrating the charging slot 110, such that the charging slot 110 is connected to one end of the drainage assembly 108. The second through hole 120 may be a hole, a slit or an opening penetrating through the receiving groove 112 (i.e., penetrating to the outside of the base 102), so that the drainage assembly 108 is communicated with the outside of the base 102 to drain water droplets (see the water droplets W1 in fig. 4) flowing through the drainage assembly 108. In some embodiments, the drainage assembly 108 may be a pipe, or the base 102 may extend to the first through hole 118 and the second through hole 120 and form a wall structure in a tunnel shape.

Referring to fig. 4, fig. 4 isbase:Sub>A side sectional view taken alongbase:Sub>A directionbase:Sub>A-base:Sub>A of fig. 1, illustratingbase:Sub>A schematic view of the electronic device connected to the base. In fig. 4, the electronic device 20 has been coupled to the charging assembly 104. When the electronic device 20 is exposed out of the charging slot 110 and a water droplet W1 is generated due to an environmental temperature difference, the water droplet W1 flows toward the filling member 106 along the surface of the electronic device 20, and after the water droplet W1 drops to the filling member 106, the water droplet W1 can continue to flow into the first through hole 118 along the filling member 106, and a flow path is formed between the first through hole 118 and the drainage assembly 108, and finally the water droplet W1 can be drained out of the base 102 through the second through hole 120.

Please refer to fig. 4 and 5. Fig. 5 is an enlarged view of fig. 2 in area 5, showing the distance between the two sides of the first opening and the distance between the two sides of the filling member. As shown in fig. 4 and 5, the first opening 114 has a first distance D1 inside, and the connection opening 107 has a second distance D2 inside. Wherein the first distance D1 is a length of the inner side of the first opening 114 in the X-axis direction in fig. 5, the second distance D2 is a length of the inner side of the connection port 107 in the X-axis direction in fig. 5, the electronic device 20 has a thickness D3, and the thickness D3 is a length of the electronic device 20 in the X-axis direction in fig. 4. In some embodiments, the first distance D1 is greater than the second distance D2, and the thickness D3 of the electronic device 20 is between the first distance D1 and the second distance D2, the thickness D3 of the electronic device 20 may also be substantially equal to the second distance D2. Specifically, when the electronic device 20 enters the base 102 through the first opening 114, since the thickness D3 of the electronic device 20 is smaller than the first distance D1, there is a slight distance between the electronic device 20 and two sides of the first opening 114, and the electronic device 20 can easily enter the range of the first opening 114 through the distance. When the electronic device 20 passes through the connection port 107, since the thickness D3 of the electronic device 20 is between the first distance D1 and the second distance D2, when the electronic device 20 enters the connection port 107, the connection port 107 is supported by the electronic device 20 and passes through the filling member 106 under the close contact of the connection port 107. Wherein, when the electronic device 20 passes through the connection port 107, the connection port 107 can tightly fit around the electronic device 20, such that the connection port 107 can block the water droplet W1 on the side of the horizontal line L2 (i.e. the side of the horizontal line L2 adjacent to the first through hole 118).

Please refer to fig. 2, fig. 4 and fig. 6. Fig. 6 is an enlarged view of the area 5 in fig. 2, showing the distances between the first end point and the second end point and the plumb line, respectively. In some embodiments, as shown in fig. 2, 4 and 6, the first through aperture 118 includes an inlet 128 and an outlet 130, the inlet 128 is located on one side of the horizontal line L2, and the outlet 130 is located on the other side of the horizontal line L2. The filler 106 is connected to the inner side of the first opening 114 and adjacent to the first through hole 118, which means that the filler 106 is adjacent to the inlet 128. In some embodiments, the inlet 128 has a first end 132 and a second end 134, and the filler 106 is adjacent to the second end 134. It can mean that the axis L3 of the filling member 106 is located at the second end 134, or that the axis L3 of the filling member 106 is located between the first end 132 and the second end 134, that is, the filling member 106 shields a portion of the inlet 128, but the inlet 128 is still exposed from the filling member 106, so that the water droplet W1 can be drained from the inlet 128 into the first through hole 118. The drainage assembly 108 is connected to the first through hole 118, which means that the drainage assembly 108 is connected to the outlet 130. In addition, according to the Z-axis direction in fig. 2, the inlet 128 is disposed at a height higher than that of the outlet 130, so that when the water droplets W1 enter the first through hole 118 through the inlet 128, the water droplets W1 can rapidly flow toward the outlet 130 and flow into the drainage assembly 108 under the action of natural gravity, thereby increasing the drainage efficiency.

As shown in fig. 2, 4 and 6, in some embodiments, the first end 132 is a third distance D4 from the plumb line L1, the second end 134 is a fourth distance D5 from the plumb line L1, and the third distance D4 is greater than or equal to the fourth distance D5, so that the first through hole 118 is inclined to increase the contact area between the first through hole 118 and the water drop. Specifically, when the water droplet W1 dropped from the electronic device 20 flows to the first through hole 118, the inclined first through hole 118 has a larger hydrophobic area, which is favorable for the water droplet W1 to flow into the first through hole 118, and thus the water drainage efficiency of the first through hole 118 is increased.

As shown in fig. 2 and fig. 3, in some embodiments, a first retaining wall 136 and a second retaining wall 138 extend from two ends of the first opening 114, the first retaining wall 136 has a first guiding surface 140, the second retaining wall 138 has a second guiding surface 142, and the first guiding surface 140 and the second guiding surface 142 face the first opening 114 respectively. Specifically, when the electronic device 20 is connected to the base 102, the first retaining wall 136 and the second retaining wall 138 can limit the electronic device 20 in the Y-axis direction of fig. 3, and when the electronic device 20 contacts the first guiding surface 140 or the second guiding surface 142, the first guiding surface 140 or the second guiding surface 142 can guide the electronic device 20 to enter the first opening 114 at a correct angle in the Y-axis direction of fig. 3. In some embodiments, the first retaining wall 136 has a first side plate set 144 on both sides thereof, the second retaining wall 138 has a second side plate set 146 on both sides thereof, and the first side plate set 144 and the second side plate set 146 extend along both sides of the first opening 114 respectively. Specifically, when the electronic device 20 moves between the first side plate group 144 and the second side plate group 146, the first side plate group 144 and the second side plate group 146 can limit the electronic device 20 in the X-axis direction in fig. 3, and the first side plate group 144 and the second side plate group 146 can guide the electronic device 20, and the X-axis direction in fig. 3 enters the first opening 114 at a correct angle. Accordingly, the base 102 can pass through the first wall 136, the second wall 138, the first side plate set 144 and the second side plate set 146, so that the charging portion 201 of the electronic device 20 can be connected to the charging connection portion 122 of the charging assembly 104 substantially along the plumb line L1.

Referring to fig. 7, fig. 7 is a cross-sectional view of an electronic device in the direction B-B of fig. 1 showing the position of a sensor and a heating element in a charging slot according to some embodiments of the present invention. As shown in fig. 7, in some embodiments, the charging device 10 further comprises a sensor 148. The sensor 148 is disposed between the filling member 106 and the second opening 116 and coupled to the charging assembly 104. The sensor 148 is used for generating an enable signal when sensing a first humidity value and generating an enable signal when sensing a second humidity value. The first Humidity value may be substantially 51% to 80% at Relative Humidity (RH), and the second Humidity value may be substantially 30% to 50% at RH. The sensor 148 may be, for example, but not limited to, a humidity sensor (e.g., a humidity-sensitive resistor or a humidity-sensitive capacitor). The sensor 148 may sense a humidity of the internal environment of the charging slot 110, and specifically, the internal environment of the charging slot 110 may refer to a space from the filling member 106 to the second opening 116. The sensor 148 may start to continuously perform humidity sensing after the charging assembly 104 is connected to the power source.

As shown in fig. 7, when the sensor 148 detects that the ambient humidity is greater than or equal to the first humidity value, the sensor 148 may send a start signal, and the charging component 104 may stop charging the electronic device 20 according to the start signal. When the sensor 148 senses that the ambient humidity is equal to or less than the second humidity value (e.g., the relative humidity is equal to or less than 50%), the sensor 148 may send an expiration signal, and the charging component 104 may resume charging the electronic device 20 (or activate the charging component 104) according to the expiration signal. For example, when the electronic device 20 is not connected to the housing 102 and the humidity of the environment inside the charging slot 110 is less than or equal to the second humidity value, the sensor 148 sends a signal to activate the charging element 104. When the electronic device 20 is connected to the base 102 and the electronic device 20 is embedded in the charging slot 110, water droplets W1 (or moisture) are gradually generated due to the temperature difference, the sensor 148 can sense that the internal humidity of the charging slot 110 gradually rises, and when the internal humidity of the charging slot 110 rises to be greater than or equal to a first humidity value (for example, the relative humidity is greater than or equal to 51%), the sensor 148 can generate a start signal according to the first humidity value, and the start signal can stop the charging operation of the charging assembly 104, so as to prevent the connection terminal 124 from being charged in a high-humidity environment, thereby protecting the coating on the surface of the connection terminal 124. When the internal humidity of the charging tank 110 is reduced to the second humidity value, the sensor 148 may generate a last signal according to the second humidity value, and the charging component 104 resumes charging according to the last signal (described later).

As further shown in fig. 7, in some embodiments, the charging device 10 further comprises a heating element 150. The heating element 150 is disposed between the filling member 106 and the second opening 116 and coupled to the sensor 148. The charging slot 110 is used for performing a heating operation according to the start signal and stopping the heating operation according to the end signal. The heating element 150 may be, for example, but not limited to, an electric heating sheet (e.g., a mica electric heating sheet, a silica gel electric heating sheet, a ceramic electric heating sheet, a metal electric heating sheet, or an etching electric heating sheet), an electric heating film, an electric heating wire, or a thermistor, or a combination of the two heating elements 150. Specifically, when the sensor 148 senses that the humidity of the internal environment of the charging slot 110 is greater than or equal to the first humidity value, which indicates that the humidity in the environment is too high, which may cause an electrolytic reaction on the coating on the surface of the connection terminal 124 or the surface of the charging portion 201, the sensor 148 sends a start signal, and the heating element 150 may perform a heating operation according to the start signal, so as to reduce the humidity of the internal environment by heating the temperature of the internal environment of the charging slot 110. When the humidity of the internal environment is equal to or less than the second humidity value, which means that the humidity of the environment does not cause the electrolytic reaction, the sensor 148 sends the expiration signal, and the heating element 150 stops heating according to the expiration signal until the heating element 150 performs heating again after the sensor 148 sends the expiration signal next time. In some embodiments, the accommodating cavity 112 further includes an air vent 151, wherein the air vent 151 is connected between the inside of the accommodating cavity 112 and the outside of the seat 102, when the heating element 150 performs a heating operation according to a start signal, moisture in the charging slot 110 evaporates into water vapor, and the water vapor can flow from an assembly gap between the sensor 148 (or the heating element 150) and the charging slot 110 to the accommodating cavity 112, and finally is discharged to the outside of the seat 102 through the air vent 151.

In some embodiments, one end of the drain assembly 108 is connected to the first through hole 118 and the third through hole 152, and the other end is connected to the second through hole 120, such that the first through hole 118 and the third through hole 152 are connected to the second through hole 120. Specifically, when the electronic device 20 is connected to the base 102, the water drops (W1, W2) as shown in fig. 8 drop along both sides of the electronic device 20 toward the filler 106, wherein the water drop W1 is drained into the drain 108 through the first through hole 118, the water drop W2 is drained into the drain 108 through the third through hole 152, and finally the water drops (W1, W2) are drained out of the base 102 through the drain 108 from the second through hole 120. It should be noted that in this embodiment, the drain member 108 may be a tap such that the drain member 108 may be connected to the first through hole 118, the second through hole 120 and the third through hole 152.

Referring to fig. 9, fig. 9 isbase:Sub>A cross-sectional view ofbase:Sub>A charging device inbase:Sub>A directionbase:Sub>A-base:Sub>A of fig. 1 showing the relative positions ofbase:Sub>A first drainage unit andbase:Sub>A second drainage unit according to some embodiments of the present invention. As shown in fig. 9, the receiving cavity 112 includes a fifth through hole 158, the first through hole 118 is connected to the second through hole 120, and the third through hole 152 is connected to the fifth through hole 158. In some embodiments, the drain assembly 108 includes a first drain unit 154 and a second drain unit 156, the first drain unit 154 is connected to the first through hole 118 at one end and the second through hole 120 at the other end, and the second drain unit 156 is connected to the third through hole 152 at one end and the fifth through hole 158 at the other end. The first drainage unit 154 and the second drainage unit 156 are not communicated with each other, and it should be noted that the second through hole 120 and the fifth through hole 158 are disposed at the bottom of the receiving groove 112 in this embodiment, and may also be disposed at the side of the receiving groove 112. The positions of the second through aperture 120 and the fifth through aperture 158 are not limited by this embodiment.

Referring to fig. 10, fig. 10 isbase:Sub>A cross-sectional view ofbase:Sub>A charging device inbase:Sub>A directionbase:Sub>A-base:Sub>A of fig. 1 showing an angle between an axis andbase:Sub>A horizontal line according to some embodiments of the present invention. As shown in fig. 10, in some embodiments, the filler 106 may be disposed obliquely inside the first opening 114. Specifically, the axis L3 intersects the horizontal line L2 and has an included angle a, and one side of the filling member 106 is adjacent to the first through hole 118. The angle a may be an acute angle, wherein the angle a may be 5 to 30 degrees, preferably 15 degrees. Taking the included angle a as 15 degrees as an example, since the inclination angle of the filler 106 is 15 degrees, the filler 106 can maintain a better sealing degree with the charging device 10, so that the filler 106 can guide the water droplets (W1, W2) to flow into the first through hole 118. For example, when the water droplets (W1, W2) on both sides of the electronic device 20 drop to the filling member 106, the water droplets W2 can flow from the side of the filling member 106 far away from the first through hole 118 to the side near the first through hole 118 by the slope of the filling member 106, and flow into the first through hole 118.

In summary, in some embodiments of the present invention, a charging device 10 is provided, which can make the water drops (W1, W2) blocked by the filler 106 from flowing to the charging assembly 104 through the filler 106 and the first through hole 118 located in the charging slot 110, and in addition, the filler 106 can guide the water drops (W1, W2) to flow to the first through hole 118 and discharge from the second through hole 120 to the outside of the base 102 of the charging device 10, so as to ensure that the charging assembly 104 does not contact the water drops (W1, W2), and maintain the charging assembly 104 to normally perform charging.
