Turning to FIG. 1, FIG. 1 is a simplified block diagram of an electronic device 100 configured with a hybrid keyboard design, in accordance with an embodiment of the present disclosure. In an example, electronic device 100 can include a first housing 102 and a second housing 104. First housing 102 can be rotatably coupled to second housing 104 using a hinge 106. First housing 102 can include a display 108.

Second housing 104 can include a keyboard 110. Keyboard 110 can include a first portion of keys 112 and a second portion of keys 114. First portion of keys 112 can include a plurality of first keys 116. Each of plurality of first keys 116 can be a mechanical key that has a first key travel. Second portion of keys 114 can include a plurality of second keys 118. Each of plurality of second keys 118 can include keys that have a second key travel, where the second key travel is less than the first key travel. For example, each of plurality of second keys 118 may be low travel keys, touch keys, or some other type of key that has a relatively low key travel. The lower key travel of second keys 118 as compared to first keys 116 can help to increase the “Z” height under second portion of keys 114 and help to accommodate components, elements, etc. that would not be able to be accommodated under first portion of keys 112. In a specific example, because of the increased Z height under second portion of keys 114, a heat pipe under second portion of keys 114 can be thicker than a heat pipe under first portion of keys 112. The term “Z stack height,” “Z height,” “Z location,” etc. refers to the height along the “Z” axis of an (x, y, z) coordinate axis or cartesian coordinate system.

It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present disclosure. Substantial flexibility is provided in that any suitable arrangements and configuration may be provided without departing from the teachings of the present disclosure.

As used herein, the term “when” may be used to indicate the temporal nature of an event. For example, the phrase “event ‘A’ occurs when event ‘B’ occurs” is to be interpreted to mean that event A may occur before, during, or after the occurrence of event B, but is nonetheless associated with the occurrence of event B. For example, event A occurs when event B occurs if event A occurs in response to the occurrence of event B or in response to a signal indicating that event B has occurred, is occurring, or will occur. Reference to “one embodiment” or “an embodiment” in the present disclosure means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrase “in one embodiment” or “in an embodiment” are not necessarily all referring to the same embodiment. The appearances of the phrase “for example,” “in an example,” or “in some examples” are not necessarily all referring to the same example.

For purposes of illustrating certain example techniques, the following foundational information may be viewed as a basis from which the present disclosure may be properly explained. End users have more media and communications choices than ever before. A number of prominent technological trends are currently afoot (e.g., more computing elements, more online video services, more Internet traffic, more complex processing, etc.), and these trends are changing the expected performance and form factor of devices as devices and systems are expected to increase performance and function while having a relatively thin profile. However, the increase in performance and/or function causes an increase in the thermal challenges of the devices and systems, especially for thin profile form factor devices.

For example, in some devices, it can be difficult to cool one or more heat sources, especially when the heat sources are located inside a relatively crowded housing that includes memory, processors, battery, etc. The relatively crowded housing can make it difficult to locate thermal solutions inside the crowded housing. Traditional passive cooling systems have separate thermal solution elements above the heat sources. The common thermal hardware in forced-air cooled laptops is a heat pipe with an attached cold plate on top of a heat source and fins that create an air-cooled heat sink.

Because even curved heat pipes must generally stay in one plane, the “Z” location (thickness dimension) of the heat sink is dictated by the height of the top of the package of the heat source being cooled. As a result, the fin height often must be limited and/or the system design may require a thicker laptop to accommodate the heat sink, especially if the heat sink includes fins. In addition, as microprocessor power increases, the heat pipe assembly must become larger and thicker to accommodate the heat generated from the microprocessor and the larger and thicker heat pipe consumes more volume in the laptop. This can require thicker laptops, which is undesirable from a user perspective. Also, even a rather thick cold plate may not have enough thermal capacitance to enable sufficient duration of high power operation such as opportunistic overclocking. What is needed is a hybrid keyboard design that can help to enable a relatively thin chassis. It would be beneficial if the hybrid keyboard design could accommodate additional cooling capabilities for a thermal system.

A system to enable a hybrid keyboard design, as outlined in FIG. 1, can resolve these issues (and others). In an example, one or more heat pipes over a heatsink and along the function and number keys (top key row) can be thickened to help allow for improved thermal performance. However, current keyboard designs are unable to accommodate the thicker one or more heat pipes. More specifically, due to the thicker one or more heat pipes, compressed current keyboard designs in the closed lid condition would put the silicone domes beneath the keys under constant state of compression, exerting undue stress on the silicon dome of the key. This is likely to affect spring properties and reliability of the silicon dome of the keys.

In an example, to accommodate the thicker one or more heat pipes, the Z-stack height of the keyboard can be reduced in one or more regions that include lesser used keys (e.g., function keys, number keys, etc.). In a specific example, the system can include touch-based keys in the selective regions that include the thicker one or more heat pipes without affecting the key stroke length. In another specific example, lesser used keys may have a lower key travel. Because of the lower key travel, the area under the keys with the lower key travel can have a Z height higher than the area under the keys with the higher key travel. This can help to accommodate an additional heat pipe or a thicker heat pipe under the less used keys with the lower key travel.

In an example implementation, electronic device 100, is meant to encompass a computer, a personal digital assistant (PDA), a laptop or electronic notebook, a clamshell computer, a cellular telephone, network elements, network appliances, or any other device, component, element, or object that includes a heat source and keys that have a key travel where the key travel under one or more keys can be reduced. Electronic device 100 may include any suitable hardware, software, components, modules, or objects that facilitate the operations thereof, as well as suitable interfaces for receiving, transmitting, and/or otherwise communicating data or information in a network environment. This may be inclusive of appropriate algorithms and communication protocols that allow for the effective exchange of data or information. Electronic device 100 may include virtual elements.

In regards to the internal structure, electronic devices 100 can include memory elements for storing information to be used in operations. Electronic device 100 may keep information in any suitable memory element (e.g., random access memory (RAM), read-only memory (ROM), erasable programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), application specific integrated circuit (ASIC), etc.), software, hardware, firmware, or in any other suitable component, device, element, or object where appropriate and based on particular needs. Any of the memory items discussed herein should be construed as being encompassed within the broad term ‘memory element.’ Moreover, the information being used, tracked, sent, or received could be provided in any database, register, queue, table, cache, control list, or other storage structure, all of which can be referenced at any suitable timeframe. Any such storage options may also be included within the broad term ‘memory element’ as used herein.

In certain example implementations, functions may be implemented by logic encoded in one or more tangible media (e.g., embedded logic provided in an ASIC, digital signal processor (DSP) instructions, software (potentially inclusive of object code and source code) to be executed by a processor, or other similar machine, etc.), which may be inclusive of non-transitory computer-readable media. In some of these instances, memory elements can store data used for operations described herein. This includes the memory elements being able to store software, logic, code, or processor instructions that are executed to carry out activities or operations.

Additionally, electronic device 100 can include one or more processors that can execute software or an algorithm. In one example, the processors could transform an element or an article (e.g., data) from one state or thing to another state or thing. In another example, activities may be implemented with fixed logic or programmable logic (e.g., software/computer instructions executed by a processor) and the heat elements identified herein could be some type of a programmable processor, programmable digital logic (e.g., a field programmable gate array (FPGA), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM)) or an ASIC that includes digital logic, software, code, electronic instructions, or any suitable combination thereof. Any of the potential processing elements, modules, and machines described herein should be construed as being encompassed within the broad term ‘processor.’

Turning to FIG. 2, FIG. 2 is a simplified block diagram of a cut-away side view of second housing 104a. Second housing 104a can include keyboard 110a and a chassis 128. Keyboard 110a can include first portion of keys 112 and second portion of keys 114. First portion of keys 112 can include plurality of first keys 116. Each of plurality of first keys 116 can be a mechanical key that has a first key travel 146. Second portion of keys 114 can include plurality of second keys 118. Each of plurality of second keys 118 can be keys that have a shortened key travel 148, where shortened key travel 148 is less than first key travel 146. For example, each of plurality of second keys 118 may be low travel keys, touch keys, or some other type of key that has a relatively low key travel.

Chassis 128 can include a support plate 130, printed circuit board (PCB) 132, heat source 134, thermal interface 136, a first heat pipe 138, and a second heat pipe 140. Support plate 130 is a plate or layer that includes switches, electronics, and support for the keys in keyboard 110a. Heat source 134 may be a heat generating device (e.g., processor, logic unit, field programmable gate array (FPGA), chip set, integrated circuit (IC), a graphics processor, graphics card, battery, memory, or some other type of heat generating device). First heat pipe 138 and second heat pipe 140 may each be a vapor chamber heat pipe, oscillating heat pipe, pulsating heat pipe, or some other type of heat transfer device that can transfer heat away heat source 134 to a thermal cooling device. Thermal interface 136 may be a thermal interface material (TIM), a cold plate, a copper spreader, or some other thermal interface that can help transfer heat from heat source 134 to first heat pipe 138.

Chassis 128 can be configured to provide an outer shell and protection for second housing 104a. Chassis 128 also defines an interior space or cavity where components of second housing 104a are located. The interior space of chassis 128 can have a limited interior chassis Z height 142. Components inside of chassis 128 must not be higher than interior chassis Z height 142. For example, PCB 132, heat source 134, thermal interface 136, and first heat pipe 138 may have a component height of 144. Component height 144 limits the Z height of a component stack as space needs to be left for support plate 130 and a user-friendly first key travel 146 for first keys 116. The amount of first key travel 146 is important for the user's experience and if first key travel 146 is too short, the user's experience can be negatively affected.

If an additional component or components need to be added to PCB 132, heat source 134, thermal interface 136, and first heat pipe 138, component height 144 needs to be increased. However, component height 144 is limited by interior chassis Z height 142. In an example, support plate 130 can be bent or curved to accommodate the additional component. For example, as illustrated in FIG. 2, support plate 130 is bent to accommodate second heat pipe 140. However, this can decrease the key travel to a shortened key travel 148. Second key 118 can be a modified key to accommodate shortened key travel 148 and allow PCB 132, heat source 134, thermal interface 136, first heat pipe 138, and second heat pipe 140 to have an extended component height 150. While user experience may be impacted by shortened key travel 148, second key 118 with shortened key travel 148 may be a seldom used key or keys so the overall user experience is not greatly impacted. For example, second key 118 may be a function key, number key, or some other type of key that is not frequently used by users.

Turning to FIG. 3, FIG. 3 is a simplified block diagram of a cut-away side view of a portion of second housing 104b. Second housing 104b can include keyboard 110b and chassis 128. Keyboard 110b can include first portion of keys 112 and second portion of keys 114. First portion of keys 112 can include plurality of first keys 116. Each of plurality of first keys 116 can be a mechanical key that has a first key travel 146. Second portion of keys 114 can include plurality of second keys 118. Each of plurality of second keys 118 can be keys that have a shortened key travel 148, where shortened key travel 148 is less than first key travel 146. For example, each of plurality of second keys 118 may be low travel keys, touch keys, or some other type of key that has a relatively low key travel.

Chassis 128 can include support plate 130, PCB 132, heat source 134, thermal interface 136, first heat pipe 138, and second heat pipe 140. Support plate 130 is a plate or layer that includes switches, electronics, and support for the keys in keyboard 110b. Heat source 134 may be a heat generating device (e.g., processor, logic unit, field programmable gate array (FPGA), chip set, IC, a graphics processor, graphics card, battery, memory, or some other type of each and second heat pipe 140 may be a vapor chamber heat pipe, oscillating heat pipe, pulsating heat pipe, or some other type of heat transfer device that can transfer heat away heat source 134 to a thermal cooling device or cooling system. Thermal interface 136 may be a thermal interface material (TIM), a cold plate, a copper spreader, or some other thermal interface that can help transfer heat from heat source 134 to first heat pipe 138 and second heat pipe 140.

Chassis 128 can be configured to provide an outer shell and protection for second housing 104b. Chassis 128 also defines an interior space or cavity where components of second housing 104b are located. If an additional component or components need to be added to PCB 132, heat source 134, thermal interface 136, and first heat pipe 138, component height 144 needs to be increased. In an example, support plate 130 can be bent or curved to accommodate the additional component or components. For example, as illustrated in FIG. 3, support plate 130 is bent to accommodate second heat pipe 140. However, this can decrease the key travel to shortened key travel 148. Second keys 118 can be a modified key to accommodate shortened key travel 148 and allow PCB 132, heat source 134, thermal interface 136, first heat pipe 138, and second heat pipe 140 to have an extended component height 150. While user experience may be impacted by shortened key travel 148, second keys 118 with shortened key travel 148 may be a seldom used key or keys so the overall user experience is not greatly impacted. For example, second keys 118 may be a function key, number key, or some other type of key that is not frequently used by users. As illustrated in FIG. 3, keyboard 110b can include two rows of second keys 118 with shortened key travel 148. The two rows of second keys 118 with shortened key travel 148 can affect a user's typing experience more than one row of second keys 118 with shortened key travel 148 and the user's typing experience should be taken into account with designing a keyboard with one or more rows of second keys 118 with shortened key travel 148.

Turning to FIG. 4, FIG. 4 is a simplified block diagram of a cut-away side view of a portion of second housing 104c. Second housing 104c can include keyboard 110 and chassis 128.

Each of plurality of second keys 118 can be keys that have a shortened key travel 148, where shortened key travel 148 is less than first key travel 146. For example, each of plurality of second keys 118 may be low travel keys, touch keys, or some other type of key that has a relatively low key travel.

Chassis 128 can include support plate 130, PCB 132, heat source 134, thermal interface 136, first heat pipe 138, and third heat pipe 152. Support plate 130 is a plate or layer that includes switches, electronics, and support for the keys in keyboard 110b. Heat source 134 may be a heat generating device (e.g., processor, logic unit, field programmable gate array (FPGA), chip set, IC, a graphics processor, graphics card, battery, memory, or some other type of heat generating device). Third heat pipe 152 may be a relatively large thickness and/or diameter heat pipe. Third heat pipe 152 may be a vapor chamber heat pipe, oscillating heat pipe, pulsating heat pipe, or some other type of heat transfer device that can transfer heat away heat source 134 to a thermal cooling device. Thermal interface 136 may be a thermal interface material (TIM), a cold plate, a copper spreader, or some other thermal interface that can help transfer heat from heat source 134 to first heat pipe 138 and second heat pipe 140.

Chassis 128 can be configured to provide an outer shell and protection for second housing 104c. Chassis 128 also defines an interior space or cavity where components of second housing 104c are located. The interior space of chassis 128 can have a limited interior chassis Z height 142. If an additional component needs to be added to PCB 132, heat source 134, thermal interface 136, or a larger heat pipe is necessary, component height 144 needs to be increased. In an example, support plate 130 can be bent or curved to accommodate the additional component. For example, as illustrated in FIG. 4, support plate 130 is bent to accommodate the relatively larger thickness and/or diameter third heat pipe 152. However, this can decrease the key travel to shortened key travel 148. Second key 118 can be a modified key to accommodate shortened key travel 148 and allow PCB 132, heat source 134, thermal interface 136, and third heat pipe 152 to have an extended component height 150. While user experience may be impacted by shortened key travel 148, second key 118 with shortened key travel 148 may be a seldom used key or keys so the overall user experience is not greatly impacted. For example, second key 118 may be a function key, number key, or some other type of key that is not frequently used by users.

Turning to FIG. 5, FIG. 5 is a simplified block diagram of a cut-away side view of a portion of second housing 104d. Second housing 104d can include keyboard 110 and chassis 128.

In an example, thermal cooling device can use fan 156 to draw air into second housing 104d though one or more inlet vents in second housing 104d and use the air to help dissipate the heat collected by first heat pipe 138 and thermal cooling device 154.

Chassis 128 can be configured to provide an outer shell and protection for second housing 104d. Chassis 128 also defines an interior space or cavity where components of second housing 104c are located. The interior space of chassis 128 can have a limited interior chassis Z height 142. In an example, support plate 130 can be bent or curved to accommodate the additional height of one or more components. For example, as illustrated in FIG. 5, support plate 130 is bent to accommodate thermal cooling device 154. However, this can decrease the key travel to a shortened key travel 148. Second key 118 can be a modified key to accommodate shortened key travel 148 and provide the height needed for thermal cooling device 154. While user experience may be impacted by shortened key travel 148, second key 118 with shortened key travel 148 may be a seldom used key or keys so the overall user experience is not greatly impacted. For example, second key 118 may be a function key, number key, or some other type of key that is not frequently used by users.

Turning to FIG. 6, FIG. 6 is a simplified block diagram of a cut-away partial side view of a portion of a keyboard 110c.

Support plate 130 can be bent or curved at transition area 158 where first portion of keys 112 transitions to second portion of keys 114a. Each of plurality of second keys 118a can have a low travel key mechanism 160. Low travel key mechanism 160 can be a mechanical low travel key mechanism or some other mechanism that allows for a mechanical key to have a relatively low travel. While user experience may be impacted by shortened key travel 148, second key 118a with shortened key travel 148a may be a seldom used key or keys so the overall user experience is not greatly impacted.

Support plate 130 can be bent or curved at transition area 158 where first portion of keys 112 transitions to second portion of keys 114b. While user experience may be impacted by the reduced key travel of shortened key travel 148b, second key 118b with shortened key travel 148 may be a seldom used key or keys so the overall user experience is not greatly impacted. For example, second key 118b may be a function key, number key, or some other type of key that is not frequently used by users.

Turning to FIG. 8, FIG. 8 is a simplified block diagram of electronic devices 100 and 100a configured with a hybrid keyboard design, in accordance with an embodiment of the present disclosure. In an example, electronic device 100 can include first housing 102 and second housing 104. First housing 102 can be rotatably coupled to second housing 104 using hinge 106. First housing 102 can include display 108.

Second housing 104 can include keyboard 110. Keyboard 110 can include first portion of keys 112 and second portion of keys 114. First portion of keys 112 can include plurality of first keys 116. Each of plurality of first keys 116 can be a mechanical key that has a first key travel. Second portion of keys 114 can include plurality of second keys 118. Each of plurality of second keys 118 can be keys that have a second key travel, where the second key travel is less than the first key travel. For example, each of plurality of second keys 118 may be low travel keys, touch keys, or some other type of key that has a relatively low key travel. The lower key travel of second keys 118 as compared to first keys 116 can help to increase the “Z” height under second portion of keys 114 and help to accommodate components, elements, etc. that would not be able to be accommodated under first portion of keys 112. In a specific example, a heat pipe under second portion of keys 114 can be thicker than a heat pipe under first portion of keys 112.

In an example, electronic device 100b can include housing 162. Housing 162 can include display 108 and keyboard 110. Keyboard 110 can include first portion of keys 112 and second portion of keys 114. First portion of keys 112 can include plurality of first keys 116. Each of plurality of first keys 116 can be a mechanical key that has a first key travel. Second portion of keys 114 can include plurality of second keys 118. Each of plurality of second keys 118 can be keys that have a second key travel, where the second key travel is less than the first key travel. For example, each of plurality of second keys 118 may be low travel keys, touch keys, or some other type of key that has a relatively low key travel. The lower key travel of second keys 118 as compared to first keys 116 can help to increase the “Z” height under second portion of keys 114 and help to accommodate components, elements, etc. that would not be able to be accommodated under first portion of keys 112. In a specific example, an additional heat pipe can be located under second portion of keys 114.
