Expansion base and electronic components

The present invention relates to an expansion base, and more particularly to an electronic component including a docking station.

With the rapid development of the information industry and the convenience brought by computer products, the daily life and work of modern people are almost related to computer products. In recent years, due to the user's need for portability and mobile commerce, whether it is a notebook computer, a tablet computer or even a smart phone, because of its small size, light weight and portability, people do not work. Restricted to a specific location, it can improve the convenience of daily use.

Because the design of such electronic products needs to meet the needs of customers that are easy to carry, the appearance and size design requirements are light, thin, short and small. However, this move makes it difficult for electronic products to effectively solve related heat dissipation problems due to their appearance limitations.

In the case of a tablet, it is not possible to use a large heat sink or fan to dissipate heat or heat the related electronic components. Therefore, in existing products, it is usually A small-sized fan mounted on a tablet, or a docking station as an additional mechanism for cooling the tablet, with the latter being configured by a fan on the docking station to assemble the tablet to the docking station Provide a corresponding cooling airflow to solve the heat dissipation problem of electronic products.

However, the above method of directly blowing the fan toward the tablet computer may cause excessive flow resistance due to the limitation of the flat shape, and the performance of the existing small-sized fan is low, and the cooling airflow cannot be provided. Once the fan speed is increased, the fan speed is increased. There will be noise problems.

Therefore, how to combine the heat dissipation effect and the appearance is indeed a problem to be considered when designing the above electronic device.

The invention provides an expansion base which improves the heat dissipation efficiency of the electronic device by the outer shape design of the guide member.

The invention provides an electronic component which improves the heat dissipation efficiency of the cooling airflow to the electronic device by the arrangement of the curved surface.

The guiding member is disposed on the body. The electronic device is carried on the body and abuts against the guide. The guide has a cavity, an inlet, and an outlet. One end of the guide is bent toward the cavity and forms a curved surface. The fan is disposed in the body and corresponds to the inlet. The fan is configured to generate a first airflow, and the first airflow flows into the cavity through the inlet and exits the cavity through the outlet. The first airflow flows along the curved surface to the electronic device, At the same time, the external space is driven to form a second airflow flowing along the curved surface to the electronic device.

The electronic component of the present invention includes a docking station and an electronic device. The docking station includes a guide and a fan. The guide has an inlet and an outlet. The fan is coupled to the inlet and is configured to generate a first flow of gas through the inlet to the guide. The electronic device has a curved surface, and the electronic device is detachably assembled to the docking station, and the curved surface corresponds to the outlet setting. The first airflow flows out of the guide through the outlet and flows along the curved surface to drive the outside air to form a second airflow to flow toward the curved surface, and the second airflow is compliant with the first airflow.

Based on the above, the electronic device and the docking station are disposed by the curved surface, and the air pressure generated when the first airflow generated by the fan flows through the curved surface forms a negative pressure effect, thereby driving the outside air to form the second airflow, and thereby Follow the first airflow to the electronic device.

1 is a schematic diagram of an electronic component in accordance with an embodiment of the present invention. 2 is a partial perspective view of the electronic component of FIG. 1 with the outer structure of the guide omitted to facilitate identification of the correspondence between the guide and the body. 3 is a partial cross-sectional view of the electronic component of FIG. 1. Referring to FIG. 1 to FIG. 3 simultaneously, the electronic component 10 includes the docking station 100 and the electronic device 200. The docking station 100 includes a body 120, a guide 110, and a fan 130. The electronic device 200 is, for example, a tablet computer that is detachably assembled to the docking station 100. The guiding member 110 has a cavity C1, an inlet T1 and an outlet T2, and one end of the guiding member 110 is bent into a curved surface S1 toward the cavity C1. The fan 130 is disposed in the body 120 and corresponds to the inlet T1. The fan 130 is configured to generate a first airflow F1.

When the electronic device 200 is assembled to the docking station 100, the curved surface S1 is between the outlet T2 and the electronic device 200. Therefore, the first airflow F1 generated by the fan 130 flows out of the docking station 100 through the outlet T2, and then flows to The curved surface S1 of the guide 110. Therefore, it can be known from Bernoulli's law that the first airflow F1 forms a pressure difference with the air outside the curved surface S1 to cause a negative pressure effect, thereby generating a second airflow F2 flowing toward the curved surface S1 and proceeding to the first direction. The air flow F1 flows to the electronic device 200. In this way, the fan 130 can improve the heat dissipation performance of the electronic device 200 by setting its own curved surface S1 to achieve the effect of draining the outside air.

Furthermore, the electronic device 200 of the present embodiment has a display surface 210 and a rear surface 220 that face each other. When the electronic device 200 is assembled to the docking station 100, the electronic device 200 is substantially carried on the body 120, and the back surface 220 of the electronic device 200 abuts The guiding member is configured to allow the guiding member 110 and the body 120 to jointly support the electronic device 200. The user can adjust the support angle of the electronic device 200 by the movable characteristic of the guiding member 110, and the electronic device 200 is further electrically connected to the body 120 to allow the input structure 122 (eg, a keyboard) on the user body 120 to be electronically Device 200 operates.

In detail, referring again to FIG. 2 and FIG. 3 , the guiding member 110 of the present embodiment includes a first winding portion 112 , a second winding portion 114 , and a connecting portion 116 . The first winding portion 112, the second winding portion 114, and the connecting portion 116 are, for example, wound by a single plate member, and the connecting portion 116 is connected to the first winding portion 112 and the second winding portion 114. between. The first winding portion 112 has a first free end E1, the second winding portion 114 has a second free end E2, the curved surface S1 is connected to the second winding portion 114, and the guiding member 110 is made, the first winding The portion 112 is substantially wound on the outer side of the curved surface S1 (ie, the first free end E1 is located outside the second free end E2), and is formed on the opposite side thereof by a cover plate to seal the wound plate member. The cavity C1 and one end of the guide 110 are bent toward the inside of the cavity C1 to form the curved surface S1 described above.

Further, the uncompressed connecting portion 116 is the first plane P1, that is, the first plane P1 is parallel to the display surface 210 and the back surface 220 of the electronic device 200, and the first winding portion 112 and the first The two winding portions 114 are each wound in a second plane P2 (that is, the first winding portion 112 can be regarded as being wound counterclockwise from the connecting portion 116 in the perspective of FIG. 3, The second winding portion 114 can be regarded as being wound in a clockwise direction from the connecting portion 116. Here, the second plane P2 is orthogonal to the first plane P1, that is, the second plane P2 can be regarded as the paper surface of FIG.

Furthermore, the inlet T1 is disposed at the connecting portion 116 and is opposite to the fan 130. The outlet T2 is formed by a gap between the first free end E1 and the second free end E2 (i.e., the cavity C1 formed by winding is not closed). Therefore, the first airflow F1 generated by the fan 130 can flow into the cavity C1 through the inlet T1 and out of the cavity C1 through the outlet T2. It is to be noted that, as shown in FIG. 2, the guide member 110 extends in the axial direction X1 on the first plane P1, wherein the axial direction X1 is the normal direction of the second plane P2. Therefore, when the first airflow F1 generated by the fan 130 flows into the cavity C1 through the inlet T1, it flows along the axial direction X1 as shown in FIG. 2 to flow out of the cavity C1 and then exit the cavity C1 through the outlet T2. . In this way, a sufficient amount of gas can be stored by the cavity C1, so that the flow rate and the flow rate of the first airflow F1 flowing out from the outlet T2 can be increased, and at the same time, the air outlet performance of the fan 130 can be improved by the structure. In addition, the inlet T1 on the connecting portion 116 has an adjustable dimension K5 along the axial direction X1, and the designer can appropriately match the size of the fan 130 and the size of the cavity C1 and the inlet T1 and the outlet T2. In order to optimize the first air flow F1 flowing out from the outlet T2.

On the other hand, in the second plane P2 in the embodiment (ie, the viewing angle shown in FIG. 2), the guiding member 110 has a first side 111 and a second side 113 opposite to each other, wherein the body 120 and the fan 130 The inlet T1 and the electronic device 200 are both located on the first side 111, and the curved surface S1 and the outlet T2 are located on the second side 113. Further, the contour of the guiding member 110 on the first side 111 thereof is tapered toward the contour of the second side 113 and finally converges close to the electronic device 200, thereby allowing the curved surface S1 to abut at the exit T2. The structure is used to guide the flow of the first airflow F1 and the second airflow F2 with the electronic device 200.

In addition, referring again to FIG. 3, the curved surface S1 has an inflection point D1, and the inflection point D1 is outside the outlet T2 to ensure that the first airflow F1 can flow along the curved surface S1 after flowing out of the chamber C1. In addition, the distance of the inflection point D1 relative to the first plane P1 is greater than the distance of the second free end E2 relative to the first plane P1, and the distance of the inflection point D1 relative to the first plane P1 is less than or equal to the first free end E1 The distance from the first plane P1. In other words, in the normal direction along the first plane P1, the inflection point D1 is substantially between the first free end E1 and the second free end E2, and for the first plane P1, the inflection point D1 Not farther than the first free end E1. Furthermore, as shown in FIG. 3, the curved surface S1 has a line segment K1 on the first plane P1, and the orthographic projection of the inflection point D1 on the first plane P1 has a distance K2 with respect to the end of the line segment K1 away from the exit T2, and The distance K2 is greater than or equal to a quarter of the line segment K1, and the distance K2 is less than or equal to one-half of the line segment K1, thereby thereby ensuring the negative pressure effect of the curved surface S1 on the first airflow F1. In addition, the first free end E1 of the embodiment is in a state of being parallel to each other with respect to the first plane P1, and if the relevant safety specification of the electronic component 10 is further considered, between the first free end E1 and the second free end E2 The gap needs to be less than or equal to 1 mm.

In other words, the guiding member 410 further includes an air guiding cover 412 that shields the first end E3 of the electronic device 200 and maintains a gap with the first end E3 to form the outlet T4, that is, the display surface 210 of the electronic device 200. The third plane P3 is taken as a reference, and the distance of the inflection point D2 relative to the display surface 210 of the electronic device 200 is less than or equal to the distance of the second end E4 of the air guiding 412 relative to the display surface 210 (ie, the third plane P3). And the orthographic projection of the curved surface S2 on the display surface 210 has a line segment K3, and the orthographic projection of the inflection point D2 on the display surface 210 has a distance K4 with respect to the end of the line segment K3 away from the exit T4, wherein the distance K4 is greater than or equal to the line segment K3 One quarter of the distance, and the distance K4 is less than or equal to one-half of the line segment K3.

In addition, the air deflector 412 has an acute angle θ2 with respect to the third plane P3, thereby controlling the flow rate of the first airflow F1 flowing out through the outlet T4 to ensure that the first airflow F1 can smoothly flow along the curved surface S2. It is ensured that the negative pressure effect formed by the first air flow F1 can effectively drive the second air flow F2 to flow to the curved surface S2.
