[0010] (Background to the invention) There is known a docking device called a port replicator that can be connected to an electronic device such as a laptop PC or a tablet PC to expand input / output terminals, etc. For example, the docking device described in Patent Document 1 expands the functionality of a laptop PC by placing the laptop PC on its top surface and connecting to the laptop PC.

[0011] The docking device described in Patent Document 1 includes a support member that is arranged to be movable up and down via an elastic member, and is configured to support the portable information device by biasing the bottom surface of the portable information device with the support member.

[0012] On the other hand, there is a demand for connecting multiple electronic devices of different sizes to a single port replicator. When connecting multiple electronic devices, the biasing force of the elastic member is set to match the weight of the heaviest electronic device. In this case, if a lighter electronic device is connected, the biasing force of the elastic member becomes excessive, causing the electronic device to bounce up when removed from the port replicator. In other words, when removing an electronic device from the port replicator, the biasing force of the elastic member causes the electronic device to bounce up.

[0013] The inventor(s) have studied port replicators that can prevent electronic devices from jumping up, and have arrived at the following invention.

[0014] A port replicator according to a first aspect of the present disclosure includes: A port replicator for placing an electronic device thereon, a main body having a mounting surface on which the electronic device is placed, the mounting surface having an accommodation hole; a pop-up portion that is received in the receiving hole and has a support surface that supports the electronic device; an elastic body that biases the pop-up portion in a first direction that causes the support surface to protrude from the accommodation hole; Equipped with the pop-up section is arranged to be movable between a first position where it is accommodated in the accommodation hole and a second position where the support surface protrudes from the main body section further than the first position, an interference member is provided on at least one of an inner wall of the accommodation hole and an outer wall of the pop-up section arranged along the inner wall, When the pop-up portion moves from the first position to the second position, the inner wall and the outer wall come into contact with each other via the interference member.

[0015] With this configuration, it is possible to provide a port replicator that can prevent the electronic device from jumping up.

[0016] In a port replicator according to a second aspect of the present disclosure, The interference member is A first protrusion provided on the inner wall, protruding in a second direction toward the outer wall, and becoming smaller in size toward the second direction in a cross section when cut along a plane intersecting the second direction; or a second projection provided on the outer wall, protruding in a third direction toward the inner wall, and becoming smaller in size toward the third direction in a cross section taken along a plane intersecting the third direction; It may include at least one of the following:

[0017] This configuration allows the pop-up section to move smoothly.

[0018] In a port replicator according to a third aspect of the present disclosure, The first protrusion or the second protrusion may be formed in a tapered shape.

[0019] This configuration allows the pop-up section to move smoothly.

[0020] In a port replicator according to a fourth aspect of the present disclosure, The first protrusion or the second protrusion may be formed to have a curved surface.

[0021] This configuration allows the pop-up section to move smoothly.

[0022] In a port replicator according to a fifth aspect of the present disclosure, The interference member is including both the first protrusion and the second protrusion, When the pop-up portion is located at the first position, the second protrusion may be located below the first protrusion, and when the pop-up portion is located at the second position, the second protrusion may be located above the first protrusion.

[0023] With this configuration, when the pop-up section is in the first position and when the pop-up section is in the second position, the interference member does not interfere, making it easy to attach an electronic device to the port replicator. In addition, the load on the interference member is reduced, improving durability.

[0024] In a port replicator according to a sixth aspect of the present disclosure, At least one of the first protrusion and the second protrusion may be made up of a plurality of protrusions.

[0025] With this configuration, the space required for arranging the interference member can be reduced, thereby improving the degree of freedom in designing the main body and the pop-up section.

[0026] In a port replicator according to a seventh aspect of the present disclosure, The plurality of protrusions may be arranged side by side in a direction intersecting the first direction.

[0027] This configuration allows the size of the interference area to be adjusted, and therefore the speed at which the pop-up section moves from the first position to the second position can be controlled, making it possible to more effectively prevent the electronic device from jumping up.

[0028] In a port replicator according to an eighth aspect of the present disclosure, The plurality of protrusions may be arranged side by side along the first direction.

[0029] This configuration allows the size of the interference area to be adjusted, and therefore the speed at which the pop-up section moves from the first position to the second position can be controlled, making it possible to more effectively prevent the electronic device from jumping up.

[0030] In a port replicator according to a ninth aspect of the present disclosure, The plurality of protrusions may be provided at both ends in a direction intersecting the movement direction of the pop-up section.

[0031] This configuration can prevent the pop-up section from tilting.

[0032] A port replicator according to a tenth aspect of the present disclosure, The interference member may include at least one of a first resin sheet disposed on the inner wall and a second resin sheet disposed on the outer wall.

[0033] With this configuration, it is possible to provide a port replicator that can reduce manufacturing costs and prevent electronic devices from jumping up.

[0034] (Embodiment 1) [Overall configuration] FIG. 1 is a perspective view showing a port replicator 1 according to a first embodiment of the present disclosure. FIG. 2 is a perspective view showing an example in which an electronic device 2 is placed on the port replicator 1 of FIG. 1. FIG. 3 is a side view of the port replicator 1 of FIG. 1. FIG. 4 is an enlarged view of an area R1 of FIG. 1. FIG. 5 is a cross-sectional view taken along line AA of FIG. 4. In the following description, the X direction in each figure may be referred to as the width direction, the Y direction as the thickness direction, and the Z direction as the depth direction.

[0035] As shown in FIGS. 1 to 5, the port replicator 1 includes a main body 11, a pop-up section 17, and an elastic member .

[0036] The port replicator 1 is a device that expands the functionality of an electronic device 2, such as a laptop PC or a tablet PC. For example, as shown in FIG. 2, when the electronic device 2 is connected to the port replicator 1, additional input / output ports 15a to 15e (see FIG. 3) can be used in addition to the input / output ports installed in the electronic device 2. In this specification, connecting the port replicator 1 and the electronic device 2 means that the port replicator 1 and the electronic device 2 are electrically connected via a connector 12, which will be described later.

[0037] <Main body> An electronic device 2, such as a laptop PC or a tablet PC, is placed on a main body 11 of the port replicator 1. In this embodiment, the main body 11 is formed in a rectangular shape in a plan view and has a placement surface 11a on which the electronic device 2 is placed. The main body 11 can be formed of, for example, resin.

[0038] 1, the placement surface 11a is inclined so that its height decreases toward the front side of the port replicator 1. By arranging the placement surface 11a at an angle, usability is improved when placing an electronic device 2 on the port replicator 1. The front side of the port replicator 1 refers to the part of the port replicator 1 facing the +Z direction in FIG.

[0039] The port replicator 1 and the electronic device 2 are fixed together by, for example, an engagement portion 11b (see FIG. 1). Specifically, the engagement portion 11b is disposed on the mounting surface 11a of the port replicator 1. The engagement portion 11b engages with a recess (not shown) provided on the bottom surface of the electronic device 2, thereby fixing the electronic device 2 to the port replicator 1. The engagement portion 11b can be configured as, for example, a hook.

[0040] Furthermore, a connector 12 for electrically connecting the port replicator 1 and the electronic device 2 is arranged on the mounting surface 11a of the main body 11. By connecting the connector 12 to a connector (not shown) provided on the electronic device 2, the port replicator 1 and the electronic device 2 can be electrically connected. In this embodiment, when the electronic device 2 is not connected to the connector, a cover 13 is arranged on the connector 12 to cover the terminals of the connector 12. When the electronic device 2 is connected to the connector, the cover 13 is open. The cover 13 is not an essential component.

[0041] As shown in Fig. 3, various input / output ports are arranged on the side surface 14 of the main body 11. An input / output port is a receptacle for a cable, a connector, or the like. In this embodiment, for example, a LAN port 15a, a USB-A port 15b, a USB-C port 15c, an HDMI (registered trademark) port 15d, and a serial port 15e are arranged on the side surface 14 of the port replicator 1. The types and number of ports arranged on the port replicator 1 are not limited to these, and may be more or less than the example shown in Fig. 3.

[0042] The mounting surface 11a of the main body 11 is provided with an accommodation hole 16. The accommodation hole 16 accommodates a pop-up section 17, which will be described later. The accommodation hole 16 is defined by an inner wall 16a, as shown in FIG. 7, which will be described later. Three first protrusions 19a to 19c are formed on the inner wall 16a. In this embodiment, the first protrusions 19a to 19c are arranged in a row in the X direction. In other words, the first protrusions 19a to 19c are arranged in a row in a direction intersecting a first direction D1 (see FIG. 4), which will be described later. The first protrusions 19a to 19c are formed to protrude in a second direction (-Z direction) toward an outer wall 17b of the pop-up section 17, which will be described later. The first protrusions 19a to 19c correspond to interference members that interfere with the outer wall 17b of the pop-up section 17.

[0043] <Pop-up section> Fig. 6 is a diagram showing the state in which the pop-up section 17 of Fig. 4 has been removed from the accommodation hole 16. Fig. 7 is a diagram showing the pop-up section 17 of Fig. 6 as viewed from a different angle.

[0044] The pop-up section 17 is a columnar member that can move in the vertical direction (Y direction) from the accommodation hole 16. In this embodiment, the pop-up section 17 is formed in a rectangular shape in a plan view. The pop-up section 17 is a component for disconnecting the electronic device 2 from the port replicator 1.

[0045] 4, the pop-up unit 17 is accommodated in the accommodation hole 16 of the main body 11 and has a support surface 17a that supports the electronic device 2. The support surface 17a comes into contact with the bottom surface of the electronic device 2 when the electronic device 2 is connected to the port replicator 1. The pop-up unit 17 is biased in a first direction D1 (+Y direction) by an elastic member 18 shown in FIG. 5 so as to cause the support surface 17a to protrude from the accommodation hole 16.

[0046] As shown in FIGS. 6 and 7, the pop-up portion 17 has an outer wall 17b that is disposed along the inner wall 16a of the accommodating hole 16. Three second protrusions 20a to 20c are formed on the outer wall 17b. The second protrusions 20a to 20c are formed to protrude in a third direction (+Z direction) from the outer wall 17b of the pop-up portion 17 toward the inner wall 16a of the accommodating hole 16. In this embodiment, the second protrusions 20a to 20c are arranged in a row in the X direction. That is, the second protrusions 20a to 20c are arranged in a row in a direction intersecting with the first direction D1. The second protrusions 20a to 20c correspond to interference members that interfere with the inner wall 16a of the accommodating hole 16.

[0047] <Elastic material> The elastic member 18 biases the pop-up portion 17 in a first direction. As shown in Fig. 5, the elastic member 18 is formed of a member having elastic force, such as a coil spring. When the engagement of the engagement portion 11b with the electronic device 2 is released, the pop-up portion 17 lifts the electronic device 2 by the biasing force of the elastic member 18, thereby disconnecting the connector of the electronic device 2 from the connector 12 of the port replicator 1.

[0048] [Pop-up operation] Fig. 8 is a partial cross-sectional view taken along line BB in Fig. 4, showing a state in which the pop-up section 17 is located at the first position. Figs. 9 and 10 are partial cross-sectional views taken along line BB in Fig. 4, showing a state in which the pop-up section 17 is located between the first position and the second position. Fig. 11 is a partial cross-sectional view taken along line BB in Fig. 4, showing a state in which the pop-up section 17 is located at the second position. An example of the operation of the pop-up section 17 will be described with reference to Figs. 8 to 11.

[0049] The pop-up section 17 is arranged to be movable between a first position shown in Fig. 8 where it is accommodated in the accommodation hole 16 and a second position shown in Fig. 11 where the support surface 17a protrudes further from the main body section 11 than the first position. When the electronic device 2 is not connected to the port replicator 1, the pop-up section 17 is positioned in the second position shown in Fig. 11 by the biasing force of the elastic member 18. When the electronic device 2 is connected to the port replicator 1, the pop-up section 17 is pushed into the accommodation hole 16 by the bottom surface of the electronic device 2. Therefore, when the electronic device 2 is connected to the port replicator 1, the pop-up section 17 is positioned in the first position.

[0050] When the engagement between the engaging portion 11b of the port replicator 1 and the electronic device 2 is released, the pop-up portion 17 is lifted in the first direction D1 by the biasing force of the elastic member 18. As the pop-up portion 17 moves in the first direction D1, the first protrusion 19b provided on the inner wall 16a of the accommodation hole 16 comes into contact with the second protrusion 20b on the outer wall 17b of the pop-up portion 17. Similarly, the first protrusion 19a comes into contact with the second protrusion 20a, and the first protrusion 19c comes into contact with the second protrusion 20c. That is, as the pop-up portion 17 moves from the first position to the second position, the inner wall 16a and the outer wall 17b come into contact with each other via the interference members (the first protrusions 19a to 19c and the second protrusions 20a to 20c).

[0051] After the first protrusions 19a-19c and the second protrusions 20a-20c come into contact with each other, as the pop-up portion 17 moves further in the first direction D1, the first protrusions 19a-19c and the second protrusions 20a-20c interfere with each other. As a result, the friction between the first protrusions 19a-19c and the second protrusions 20a-20c slows down the speed at which the pop-up portion 17 moves in the first direction D1. As the pop-up portion 17 moves further in the first direction D1, the first protrusions 19a-19c and the second protrusions 20a-20c no longer interfere with each other, as shown in FIG. 10. The pop-up portion 17 moves further and stops at the second position, as shown in FIG. 11.

[0052] The first protrusions 19a to 19c and the second protrusions 20a to 20c interfere with each other, thereby slowing down the speed at which the pop-up section 17 moves, thereby preventing the electronic device 2 from jumping up.

[0053] 8 to 11, in this embodiment, first protrusion 19b is formed so that it becomes smaller in size toward the second direction (-Z direction) in a cross section taken along a plane (YZ plane) intersecting the second direction (-Z direction). More specifically, first protrusion 19b is formed in a tapered shape in a cross section taken along the YZ plane. First protrusions 19a and 19c are also formed in a tapered shape in a cross section taken along the YZ plane.

[0054] Furthermore, in this embodiment, the second protrusions 20b are formed so that they become smaller in size in the third direction (+Z direction) in a cross section taken along a plane (YZ plane) intersecting the third direction. More specifically, the second protrusions 20b are formed in a tapered shape in a cross section taken along the YZ plane. The second protrusions 20a and 20c are also formed in a tapered shape in a cross section taken along the YZ plane.

[0055] By forming the first protrusions 19a to 19c and the second protrusions 20a to 20c in a tapered shape, even when the first protrusions 19a to 19c and the second protrusions 20a to 20c come into contact with each other and interfere with each other, the pop-up section 17 can be moved smoothly. This reduces the impact on the electronic device 2, and prevents the electronic device 2 from jumping up.

[0056] In this embodiment, as shown in Fig. 8, when the pop-up section 17 is located at the first position, the second protrusions 20a to 20c are located below the first protrusions 19a to 19c. Also, as shown in Fig. 11, when the pop-up section 17 is located at the second position, the second protrusions 20a to 20c are located above the first protrusions 19a to 19c. In other words, when the pop-up section 17 is located at the first position and the second position, the first protrusions 19a to 19c and the second protrusions 20a to 20c are arranged so that they do not interfere with each other.

[0057] [effect] According to the above-described embodiment, it is possible to provide a port replicator 1 that prevents the electronic device from bouncing up. When the connection between the port replicator 1 and the electronic device 2 is released, the electronic device 2 is lifted by the pop-up portion 17. The pop-up portion 17 of the port replicator 1 is lifted by an elastic member 18 that has a predetermined biasing force. It is sufficient for the elastic member 18 to have a biasing force that is sufficient to lift the electronic device 2 with the pop-up portion 17 and release the connection with the port replicator 1. When the port replicator 1 is compatible with multiple electronic devices 2 of different weights, the biasing force of the elastic member 18 is set to a value that matches the heaviest electronic device 2.

[0058] In the above-described embodiment, by providing interference members on the outer wall 17b of the pop-up portion 17 and the inner wall 16a of the accommodation hole 16, friction occurs when the pop-up portion 17 moves in the first direction D1. This makes it possible to slow down the speed at which the pop-up portion 17 moves in the first direction D1. When the speed at which the pop-up portion 17 moves is slowed down, even when a lighter electronic device 2 is connected to the port replicator 1, it is possible to prevent the electronic device 2 from being lifted up by the pop-up portion 17 when it is removed.

[0059] In the above-described embodiment, an example has been described in which protrusions serving as interference members are formed on both the inner wall 16a of the accommodating hole 16 and the outer wall 17b of the pop-up portion 17, but the present invention is not limited to this. The interference member may be formed on at least one of the inner wall 16a of the accommodating hole 16 and the outer wall 17b of the pop-up portion 17.

[0060] In the above-described embodiment, the first protrusions 19a-19c and the second protrusions 20a-20c are formed in a tapered shape, but this is not limiting. At least one of the first protrusions 19a-19c and the second protrusions 20a-20c may be formed in a curved shape, for example. Alternatively, at least one of the first protrusions 19a-19c and the second protrusions 20a-20c may be formed in a shape that tapers toward the tip.

[0061] In the above-described embodiment, an example in which three first protrusions 19a to 19c and three second protrusions 20a to 20c are provided has been described, but the present invention is not limited to this. The first protrusion and the second protrusion may each be formed by a single protrusion or a plurality of protrusions.

[0062] In the above-described embodiment, the first protrusions 19a-19c and the second protrusions 20a-20c are arranged side by side in a direction intersecting the first direction D1, but the present invention is not limited to this. For example, at least one of the first protrusions or the second protrusions may be arranged side by side along the first direction D1.

[0063] (Variation) FIG. 12 is a perspective view showing the pop-up section 117 of the port replicator 1A according to a first modification of the first embodiment. FIG. 13 is a perspective view of the pop-up section 117 of the port replicator 1A of FIG. 12, viewed from another direction. As shown in FIGS. 12 and 13, one protrusion 21 and one protrusion 22 may be formed on each of the inner wall 116a of the accommodation cavity 116 and the outer wall 117b of the pop-up section 117. In the first modification, a first rib-like protrusion 21 is formed on the inner wall 116a of the accommodation cavity 116, and a second rib-like protrusion 22 is formed on the outer wall 117b of the pop-up section 117. By changing the width and size of the protrusions 21 and 22, the area of ​​the interfering portion can be changed, and the movement speed of the pop-up section 117 can be appropriately adjusted.

[0064] FIG. 14 is a cross-sectional view showing a pop-up section 217 of a port replicator 1B according to a second modification of the first embodiment. As shown in FIG. 14, in the port replicator 1B, a first resin sheet 23 is disposed on an inner wall 216a of the accommodation cavity 216, and a second resin sheet 24 is disposed on an outer wall 217b of the pop-up section 217. In the second modification, the first resin sheet 23 and the second resin sheet 24 correspond to interference members. The first resin sheet 23 and the second resin sheet 24 may be formed of a synthetic resin such as polycarbonate. Even when a resin sheet is disposed instead of a protrusion, the movement speed of the pop-up section 117 can be reduced by friction. Alternatively, a resin sheet may be disposed on either the inner wall 216a of the accommodation cavity 216 or the outer wall 217b of the pop-up section 217, and a protrusion may be formed on the other.

[0065] 15 is a cross-sectional view showing a pop-up section 317 of a port replicator 1C according to a third modification of the first embodiment. As shown in FIG. 15, the first protrusion 319 and the second protrusion 320 may be provided on each of two ends (both ends) facing each other in a direction intersecting the movement direction (first direction D1) of the pop-up section 317. That is, in the Z direction intersecting the movement direction (first direction D1) of the pop-up section 317, the first protrusions 319 may be formed on inner walls 316a at both ends of the accommodating hole 316, and the second protrusions 30a may be formed on outer walls 317b at both ends of the pop-up section 317.
