  Hereinafter, embodiments will be described with reference to the drawings.

(First embodiment)
1 to 3 disclose a television receiver 1 according to the first embodiment. The television receiver 1 is an example of an “electronic device”. As shown in FIG. 1, the television receiver 1 includes a display unit 2 and a stand 3 that supports the display unit 2.

  The display unit 2 includes a housing 4 and a display device 5 accommodated in the housing 4. The display device 5 has a display screen 5a. The housing 4 is provided with an opening 4a through which the display screen 5a is exposed.

  As shown in FIG. 2, the housing 4 accommodates a circuit board 6 and a battery unit 7. The details of the housing 4, the circuit board 6, and the battery unit 7 are the same as those in the electronic device 11 of the second embodiment. Therefore, the second embodiment will be described in detail as a representative, and detailed description thereof in this embodiment will be omitted. In FIGS. 1 to 3, configurations having the same or similar functions as those of the second embodiment are denoted by the same reference numerals.

(Second Embodiment)
Next, the electronic device 11 according to the second embodiment will be described with reference to FIGS. The electronic device 11 is, for example, a notebook portable computer (notebook PC). Note that electronic devices to which the present embodiment is applicable are not limited to the above examples. This embodiment is widely applicable to other electronic devices such as a slate portable computer (slate PC), a mobile phone including a smartphone, and a game machine.

  As shown in FIG. 4, the electronic device 11 includes a first unit 12, a second unit 13, and a hinge part 14. The first unit 12 is a main unit on which a main board is mounted, for example. The first unit 12 includes a first housing 4. An example of the first housing 4 is made of a metal such as a magnesium alloy and has a relatively high rigidity. The 1st housing | casing 4 has the upper wall 16, the lower wall 17, and the surrounding wall 18, and is formed in the flat box shape.

  When the electronic device 11 is placed on a desk, the lower wall 17 faces the desk surface (mounting surface). The lower wall 17 is provided with, for example, a plurality of leg portions 19 (see FIGS. 7 and 11) in contact with the desk surface. The upper wall 16 is located on the side opposite to the lower wall 17. The upper wall 16 extends substantially parallel to the lower wall 17 with a space between the upper wall 16 and the lower wall 17. The upper wall 16 is an example of a “first wall”. The lower wall 17 is an example of a “second wall”.

  The peripheral wall 18 connects the peripheral edge of the lower wall 17 and the peripheral edge of the upper wall 16. Note that both or one of the lower wall 17 and the upper wall 16 may be bent toward the peripheral wall 18 and connected to the peripheral wall 18 in a substantially arc shape.

  The first housing 4 has a first end 21 and a second end 22. The first end 21 is, for example, a front end. The second end 22 is, for example, a rear end, and is located on the side opposite to the first end 21. The peripheral wall 18 includes a front wall 18a, a rear wall 18b, a first side wall 18c (for example, a left side wall), and a second side wall 18d (for example, a right side wall).

  The front wall 18 a is located at the first end 21. The front wall 18a extends in the longitudinal direction of the housing 4 (the lateral width direction of the housing 4). The rear wall 18 b is located at the second end 22. The rear wall 18b extends substantially parallel to the front wall 18a. The first side wall 18c and the second side wall 18d extend in a direction intersecting with the front wall 18a and the rear wall 18b (for example, a direction substantially orthogonal). The first side wall 18c and the second side wall 18d extend in the short direction of the housing 4 (the depth direction of the housing 4). The first side wall 18c and the second side wall 18d connect the end of the front wall 18a and the end of the rear wall 18b, respectively.

  As shown in FIG. 4, the second unit 13 is a display unit, for example, and includes a second housing 24 and the display device 5 accommodated in the second housing 24. The display device 5 is, for example, a liquid crystal display, but is not limited to this. The display device 5 has a display screen 5a on which images and videos are displayed. The second housing 24 has an opening 4a through which the display screen 5a is exposed.

  The second housing 24 is connected to the second end 22 of the first housing 4 by the hinge portion 14 so as to be rotatable (openable and closable). Thereby, the 2nd unit 13 can rotate between the 1st position where the 1st unit 12 and the 2nd unit 13 overlap, and the 2nd position where the 1st unit 12 and the 2nd unit 13 are opened. It is.

  Next, the mounting structure of the electronic device 11 will be described. For convenience of explanation, “first housing 4” is simply read as “housing 4” below.

  As shown in FIGS. 4 and 5, a keyboard 25 and a touch pad 26 are provided on the upper wall 16 of the housing 4. The keyboard 25 is an example of a “first input unit”. The touch pad 26 is an example of a “second input unit”. The first and second input units are not limited to the above, and may be a touch panel (touch sensor) or other input device.

  As shown in FIG. 4, the housing 4 includes a lower cover 27 (base) and an upper cover 28 (cover). The lower cover 27 includes the lower wall 17 and a part of the peripheral wall 18. The upper cover 28 includes the upper wall 16 and a part of the peripheral wall 18. The housing 4 is configured by combining the lower cover 27 and the upper cover 28.

  FIG. 6 shows the inner surface of the upper cover 28 by turning the upper cover 28 upside down. The upper cover 28 includes a keyboard attachment portion 31 to which the keyboard 25 is attached, and a touch pad attachment portion 32 to which the touch pad 26 is attached. The keyboard attachment portion 31 is an example of a “first attachment portion”. The touch pad attachment portion 32 is an example of a “second attachment portion”.

  The keyboard attachment portion 31 extends in the longitudinal direction of the housing 4 and covers substantially the entire width of the housing 4. As shown in FIG. 7, the keyboard attachment portion 31 is recessed from the upper wall 16 (palm rest 36). Thereby, the keyboard 25 attached to the keyboard attachment part 31 is substantially the same height as the upper wall 16 (palm rest 36) or slightly higher than the upper wall 16 (palm rest 36).

  As shown in FIG. 6, the keyboard attachment part 31 of this embodiment has a honeycomb structure. That is, the keyboard attachment portion 31 includes a plurality of hexagonal openings 31a and a plurality of beams 31b (support portions) extending between the openings 31a. The plurality of beams 31b are connected to each other to form a hexagonal frame. These beams 31b are provided in substantially the entire area of the keyboard mounting portion 31, and support the keyboard 25 from below.

  By having such a honeycomb structure, the keyboard mounting portion 31 can simultaneously achieve strength (rigidity) and weight reduction. Thereby, even if a user taps the keyboard 25 strongly, the keyboard attachment part 31 is hard to bend.

  As shown in FIG. 6, the touch pad attachment portion 32 is located between the keyboard attachment portion 31 and the first end portion 21. As shown in FIGS. 8 and 20, the touch pad mounting portion 32 is recessed from the upper wall 16 (palm rest 36). The touch pad mounting portion 32 supports the touch pad 26 from the inside (ie, the lower side) of the housing 4.

  As illustrated in FIGS. 8 and 20, the touch pad attachment portion 32 includes a first portion 32 a, a second portion 32 b, and a third portion 32 c. The first portion 32 a is adjacent to the keyboard attachment portion 31. The first portion 32 a is recessed shallower than the keyboard attachment portion 31. A flat plate portion of the touch pad 26 is placed on the first portion 32a.

  The second portion 32 b is located between the first portion 32 a and the first end portion 21. The second part 32 b is recessed deeper than the first part 32 a and shallower than the keyboard attachment portion 31. A component mounting portion of the touch pad 26 is placed on the second portion 32b.

  The third portion 32 c is located between the second portion 32 b and the first end portion 21. The third portion 32c is deeper than the second portion 32b and is recessed deeper than the keyboard attachment portion 31, for example. A button 34 (touch pad button) of the touch pad 26 and a switch 35 (switch board) operated by the button 34 are attached to the third portion 32c.

  As shown in FIG. 4, palm rests 36 are provided on both the left and right sides of the touch pad mounting portion 32. The palm rest 36 extends between the keyboard attachment portion 31 and the first end portion 21. As shown in FIG. 6, honeycomb ribs (ribs formed with a honeycomb structure) are provided on the inner surface of the palm rest 36. Thereby, the palm rest 36 is hard to bend even if the user strongly presses it.

  As shown in FIGS. 9 and 10, a pair of speakers 37 and 38, a circuit board 6, and a battery unit 7 are accommodated in the housing 4. The speakers 37 and 38, the circuit board 6, and the battery unit 7 are attached (fixed) to the inner surface of the upper wall 16.

  As shown in FIGS. 5 and 10, the pair of speakers 37 and 38 are arranged separately at the left and right ends. The first speaker 37 is along the first side wall 18c and the front wall 18a. The second speaker 38 is along the second side wall 18d and the front wall 18a.

  As shown in FIG. 5, the first speaker 37 includes a speaker 41 (speaker body) and a speaker box 42 that houses the speaker 41. The speaker 41 has a relatively large diameter in order to achieve high sound quality. The large-diameter speaker 41 is mounted substantially parallel to the palm rest 36 (upper wall 16) in order to make the housing 4 thinner. That is, the diaphragm of the speaker 41 faces the inner surface of the palm rest 36 (upper wall 16).

  The speaker box 42 has a first sound emitting hole 42a (first opening) and a second sound emitting hole 42b (second opening). The first sound emission hole 42a emits sound in the middle and high range. The first sound emitting hole 42 a faces the front wall 18 a of the housing 4. In other words, the first sound emission hole 42a is not opened in the vibration direction of the speaker 41 but in a direction intersecting with the vibration direction (for example, a direction substantially orthogonal).

  Between the speaker 41 and the first sound emitting hole 42a, a guide 43 for guiding the sound from the speaker 41 toward the first sound emitting hole 42a is provided. By this guide 43, a sound passing area (sound passing space, sound passing part) is provided between the speaker 41 and the first sound emitting hole 42a. The guide 43 is composed of, for example, a cushion (sponge).

  As shown in FIG. 4, the front wall 18a of the housing 4 has an opening 44 that faces the first sound emitting hole 42a. The mid-high range sound from the first speaker 37 is emitted to the outside of the housing 4 through the opening 44 of the front wall 18a.

  As shown in FIG. 10, the second sound emission hole 42 b is a so-called bass reflex hole, and a sound in a low sound range (for example, several hundred Hz) is emitted. The second sound emitting hole 42 b is open in the housing 4 in the longitudinal direction of the housing 4. That is, low-frequency sound is emitted into the housing 4. In the present embodiment, the low frequency range is not directional, and the low frequency range is resonated using the internal space of the housing 4. As a result, the sound in the low frequency range is enhanced.

  As shown in FIG. 10, the speaker box 42 extends along the front wall 18a. The second sound emitting hole 42b is provided at an end of the speaker box 42 and emits a low sound toward the second side wall 18d. The low sound emitted from the second sound emitting hole 42b is transmitted to the outside by passing through a small hole (for example, the touch pad mounting portion 32 or screw hole) of the housing 4 or by vibrating the product itself.

  Since the configuration of the second speaker 38 is substantially the same as that of the first speaker 37, the configuration having the same function is denoted by the same reference numeral, and the description thereof is omitted.

  As shown in FIG. 10, the speaker box 42 of the second speaker 38 also extends along the front wall 18a. The second sound emitting hole 42b of the second speaker 38 is provided at the end of the speaker box 42 and emits a low sound toward the first side wall 18c. Here, the second sound emitting hole 42b of the first speaker 37 and the second sound emitting hole 42b of the second speaker 38 face each other. As a result, the low sound from the first speaker 37 and the low sound from the second speaker 38 are combined in the housing 4 and enhanced and transmitted to the outside.

  As shown in FIG. 10, the circuit board 6 is provided near the second end 22 of the housing 4. The circuit board 6 has a rectangular shape. The longitudinal direction of the circuit board 6 is along the longitudinal direction of the housing 4. The circuit board 6 is, for example, a main board.

  On the circuit board 6, a heat generating component 46, a memory 47, and various electronic components 48 are mounted. An example of the heat generating component 46 is a CPU (Central Processing Unit), but is not limited thereto. The heat generating component 46 may be a graphic chip or other components, and various components for which heat dissipation is desired are appropriate.

  The housing 4 accommodates a fan 49, a heat sink 50, and a heat pipe 51. An exhaust hole 52 (opening) is provided in the rear wall 18 b of the housing 4. The heat sink 50 faces the exhaust hole 52. The fan 49 faces the heat sink 50.

  As shown in FIG. 11, a first intake hole 53 (opening) is provided in the lower wall 17 of the housing 4. The first intake hole 53 faces the fan 49. As shown in FIGS. 5 and 10, the fan 49 is a centrifugal type, and has two suction ports 49a and 49b provided separately on the upper and lower surfaces, and a discharge port 49c provided on the side surface.

  As shown in FIG. 10, the first suction port 49 a faces the first intake hole 53 of the lower wall 17 of the housing 4. The fan 49 communicates with the first intake hole 53 and sucks air outside the housing 4. As shown in FIG. 5, the second suction port 49 b is located on the side opposite to the first suction port 49 a and faces the upper wall 16 of the housing 4. The fan 49 sucks the air inside the housing 4 through the second suction port 49b. The discharge port 49 c faces the heat sink 50. The fan 49 sends wind toward the heat sink 50.

  As shown in FIG. 11, the housing 4 has a second intake hole 54 (opening). The second intake hole 54 is provided outside the battery unit 7 and faces the circuit board 6. The fan 49 sucks air flowing into the housing 4 from the second intake hole 54 through the second suction port 49b.

  The heat pipe 51 is an example of a “heat conducting member”. The heat pipe 51 extends between the heat generating component 46 and the heat sink 50 and thermally connects the heat generating component 46 and the heat sink 50.

  As shown in FIG. 10, the battery unit 7 is attached between the circuit board 6 and the first end 21 of the housing 4. The battery unit 7 is an example of each of “battery pack”, “battery”, “battery”, “unit”, and “module”.

  The battery unit 7 has a rectangular shape. The longitudinal direction of the battery unit 7 is substantially the same as the longitudinal direction of the housing 4. The battery unit 7 extends substantially in parallel with the circuit board 6, and extends over the entire width of the housing 4, for example. As shown in FIG. 10, the battery unit 7 and the circuit board 6 partially overlap in a direction (for example, a substantially orthogonal direction) intersecting the thickness direction of the housing 4. That is, the battery unit 7 and the circuit board 6 partially overlap in a direction substantially parallel to the upper wall 16.

  As shown in FIG. 10, the battery unit 7 is located between the circuit board 6 and the speakers 37 and 38. Further, the front end portion of the battery unit 7 is located between the first speaker 37 and the second speaker 38.

Next, the structure of the battery unit 7 will be described in detail.
As shown in FIG. 12, the battery unit 7 has a plurality of battery cells 61 (battery cells) and a case 62 (battery case). For example, eight battery cells 61 are provided. The battery cell 61 has a rectangular plate shape. The longitudinal direction of the battery cell 61 substantially coincides with the longitudinal direction of the battery unit 7.

  The battery cells 61 are arranged in two rows by four. That is, the battery cell 61 includes four battery cells 61 located in the first row R1 and four battery cells 61 located in the second row R2. In each row, the battery cells 61 are arranged in the longitudinal direction.

  The battery cell 61 of this embodiment is plate-shaped and relatively thin. The battery cell 61 has a first surface 61a, a second surface 61b, and a third surface 61c (see FIG. 17). The first surface 61a is, for example, an upper surface. The 2nd surface 61b is located in the opposite side to the 1st surface 61a, for example, is a lower surface. The third surface 61c extends between the first surface 61a and the second surface 61b, and extends in a direction intersecting the first surface 61a and the second surface 61b (for example, a direction that is substantially orthogonal). The third surface 61c is, for example, a side surface. The third surface 61c is smaller than the first surface 61a and the second surface 61b. The corner portion C1 between the third surface 61c and the first surface 61a and the corner portion C2 between the third surface 61c and the second surface 61b each have, for example, an arcuate roundness.

  As shown in FIG. 12, the plurality of battery cells 61 are aligned with each other in a direction (for example, a direction substantially orthogonal) intersecting the plate thickness direction (thickness direction) of the battery cells 61. That is, the battery cells 61 are arranged with the third surfaces 61c facing each other.

  As shown in FIG. 12, the case 62 includes a base 64 (main body portion) and a cover 65 attached to (combined with) the base 64. The battery cell 61 is located between the base 64 and the cover 65.

  The base 64 is formed, for example, in a frame structure composed of a frame and a beam, and is opened upward and downward. More specifically, the base 64 has a frame portion 64a and a beam portion 64b. The frame portion 64 a is a frame that integrally surrounds the plurality of battery cells 61 and is located outside the plurality of battery cells 61. The frame portion 64 a constitutes the peripheral wall of the base 64. The frame portion 64 a is a rib that stands in the thickness direction of the battery cell 61 and faces the third surface 61 c of the battery cell 61.

  The beam portions 64 b are provided in a lattice shape inside the frame portion 64 a and are positioned between the plurality of battery cells 61. The beam portion 64 b is a rib that stands in the thickness direction of the battery cell 61, and extends between the third surfaces 61 c of the plurality of battery cells 61.

  FIG. 17 shows the beam portion 64b in detail. As shown in FIG. 17, the beam portion 64b includes a first portion 64ba, a second portion 64bb, and a third portion 64bc. The first portion 64ba extends substantially parallel to the second surface 61b of the battery cell 61 and enters between the plurality of battery cells 61. A part of the first portion 64ba faces the third surface 61c of the battery cell 61. A part of the first portion 64ba faces the corner C2 of the battery cell 61 in a direction substantially parallel to the second surface 61b of the battery cell 61.

  The second portion 64 bb is a rib that stands in the thickness direction of the battery cell 61 and extends along the third surface 61 c of the battery cell 61. The second portion 64bb faces the third surface 61c of the battery cell 61. The second portion 64bb is provided, for example, at substantially the entire length of the beam portion 64b, and reinforces the beam portion 64b.

  The third portion 64 bc extends from the end of the first portion 64 ba and faces the second surface 61 b of the battery cell 61. The third portion 64bc is thinner than the first portion 64ba and less intense than the first portion 64ba. The third portion 64bc regulates, for example, the vertical position of the battery cell 61, but may not have substantial strength. The frame portion 64a also has substantially the same configuration as the beam portion 64b.

  On the other hand, as shown in FIG. 12, the cover 65 includes a first portion 71 having a skeleton structure, and second and third portions 72 and 73 serving as lid portions, respectively. Here, the first portion 71 will be described, and the second and third portions 72 and 73 will be described later. The first portion 71 includes a frame portion 71a and a beam portion 71b. The frame portion 71 a is located corresponding to a part of the frame portion 64 a of the base 64 and faces the frame portion 64 a of the base 64. For example, the frame portion 71 a extends toward the base 64 and is connected to the frame portion 64 a of the base 64.

  The beam portion 71 b is located corresponding to the beam portion 64 b of the base 64 and faces the beam portion 64 b of the base 64. As shown in FIG. 17, the beam portion 71b has a first portion 71ba and a second portion 71bb. The first portion 71ba extends substantially parallel to the first surface 61a of the battery cell 61 and enters between the plurality of battery cells 61. The first portion 71ba faces the second portion 64bb of the beam portion 64b of the base 64 in the thickness direction of the battery cell 61. A part of the first portion 71ba faces the third surface 61c of the battery cell 61. A part of the first portion 71ba faces the corner C1 of the battery cell 61 in a direction substantially parallel to the first surface 61a of the battery cell 61.

  The second portion 71bb extends from the end of the first portion 71ba and faces the first surface 61a of the battery cell 61. The second portion 71bb is thinner than the first portion 71ba and less intense than the first portion 71ba. The second portion 71bb may not have substantial strength. The second portion 71bb opens a gap with the battery cell 61.

  FIG. 18 shows a state in which external pressure is applied to the case 62. When external pressure is applied, the beam portion 71 b of the cover 65 may be bent toward the beam portion 64 b of the base 64. In this case, the beam portion 71 b of the cover 65 abuts on the beam portion 64 b of the base 64 and is supported by the beam portion 64 b of the base 64.

The surface 73 s of the third portion 73 is located on substantially the same plane as the surface 71 s of the first portion 71.

  Next, the relationship between the structure of the housing 4 and the battery unit 7 will be described. Here, FIG. 19, FIG. 21, and FIG. 22 schematically show the structure for convenience of explanation.

  As illustrated in FIGS. 20 and 22, the housing 4 includes a first region 111, a second region 112, and a third region 113.

The second region 112 is thicker in the housing 4 than the first region 111. The third region 113 (third portion) is provided with the third portion 32 c of the touch pad mounting portion 32. The third region 113 has a smaller thickness in the housing 4 than the first region 111.

  As shown in FIGS. 20 and 22, the battery cells 61 located in the first row R <b> 1 are located in the first region 111. That is, the first portion 71 of the cover 65 is located in the first region 111 and is located below the keyboard attachment portion 31.

  On the other hand, the battery cells 61 located in the second row R2 are located in the second region 112. That is, the second portion 72 of the cover 65 is located in the second region 112 having a space, and is located below the first and second portions 32 a and 32 b of the palm rest 36 and the touch pad attachment portion 32.

  As shown in FIGS. 6 and 17 to 19, the upper wall 16 (keyboard attachment portion 31) of the housing 4 has first and second protrusions 121 and 122. The first and second projecting portions 121 and 122 are provided on the inner surface of the housing 4 and project into the housing 4.

  The first protruding portion 121 protrudes toward the beam 82 of the battery unit 7. As shown in FIG. 6, the first protrusion 121 is a rib extending along the beam 82. When the upper wall 16 of the housing 4 bends, the first protrusion 121 is supported by the beam 82. Thereby, as shown in FIG. 18, before the upper wall 16 (keyboard attachment portion 31) contacts the battery cell 61, the bending of the upper wall 16 is suppressed.

  As shown in FIG. 6, the second protrusion 122 extends in a direction intersecting with the first protrusion 121 (for example, a direction substantially orthogonal). The 2nd protrusion part 122 is extended in the longitudinal direction of the housing | casing 4, for example. The second protrusion 122 protrudes toward the frame 81 of the battery unit 7. When the upper wall 16 of the housing 4 bends, the second protrusion 122 is supported by the frame 81. Thereby, before the upper wall 16 (keyboard attachment part 31) contacts the battery unit 7, the bending of the upper wall 16 is suppressed.

Next, some mounting structures of this embodiment will be described.
As shown in FIG. 10, the end portion 131 (front end portion) of the battery unit 7 extends in the longitudinal direction of the housing 4 and covers substantially the entire width of the housing 4. The end 131 of the battery unit 7 extends along the sound emission direction of the second sound emission hole 42 b of the first speaker 37. That is, the end 131 of the battery unit 7 extends in a direction from the second sound emitting hole 42 b of the first speaker 37 toward the second sound emitting hole 42 b of the second speaker 38.

  Further, the end 131 of the battery unit 7 extends along the sound emitting direction of the second sound emitting hole 42 b of the second speaker 38. That is, the end 131 of the battery unit 7 extends in a direction from the second sound emitting hole 42 b of the second speaker 38 toward the second sound emitting hole 42 b of the first speaker 37.

  Thereby, the sound emitted from the second sound emitting hole 42 b of the first speaker 37 and the sound emitted from the second sound emitting hole 42 b of the second speaker 38 are guided along the end 131 of the battery unit 7. , Collide with each other in the housing 4 and strengthen. That is, the battery unit 7 constitutes a part of a guide portion that guides the sound from the first and second speakers 37 and 38 in the housing 4.

  As shown in FIG. 11, the end portion 132 (rear end portion) of the battery unit 7 extends in the longitudinal direction of the housing 4 and covers substantially the entire width of the housing 4. Thus, a wall extending in the longitudinal direction of the housing 4 is formed in the housing 4 by the end portion 132 of the battery unit 7. The air taken in from the second intake hole 54 is guided by the wall and flows toward the fan 49. That is, the battery unit 7 constitutes a part of a rectification unit that guides the flow of wind in the housing 4. In other words, the end 132 of the battery unit 7 and the rear wall 18 b of the housing 4 constitute a part of the duct from the second intake hole 54 toward the fan 49.

  As shown in FIG. 11, the leg 19 provided on the lower wall 17 of the housing 4 is provided outside the battery unit 7. This makes it difficult for a load to be applied to the battery unit 7.

According to such a configuration, the electronic device 11 can be thinned.
A general battery case is made of a hard plastic as a whole. In such a configuration, a thickness is inevitably required on the upper and lower sides of the battery cell 61, and the battery unit is inevitably relatively thick.

Greater than the thickness of According to such a configuration, stress from the outside of the battery unit 7 is received by the beam 82 and is not easily applied directly to the battery cell 61.

  For this reason, the battery cell 61 can be protected even if the entire battery case 62 is not made of hard plastic. Thereby, thickness reduction and weight reduction of the battery unit 7 can be achieved, maintaining mechanical strength. This can reduce the thickness and weight of the electronic device 11.

According to such a configuration, since the frame 81 and the beam 82 form a relatively strong protective structure for protecting the battery cell 61, a part of the case 62 is made thinner and lighter with lower strength. Can be configured. Thereby, thickness reduction and weight reduction of the battery unit 7 can be achieved.

  In the present embodiment, the housing 4 has a protruding portion 121 that is provided on the inner surface of the housing 4 and protrudes toward the beam 82. According to such a configuration, when force is applied to the housing 4 and the housing 4 bends, the protrusion 121 is reliably supported by the beam 82 before the inner surface of the housing 4 contacts the battery cell 61. . That is, the impact / load from the housing 4 can be reliably released to the beam 82 of the case 62 through the protrusion 121. Thereby, a part of case 62 can be further comprised with a thin and light member with weak intensity | strength, and can achieve thickness reduction and weight reduction of the battery unit 7. FIG.

  In the present embodiment, the protruding portion 121 is a rib extending along the beam 82. According to such a configuration, the protruding portion 121 is more reliably supported by the beam 82. Thereby, a part of case 62 can be further comprised with a thin and light member with weak intensity | strength, and can achieve thickness reduction and weight reduction of the battery unit 7. FIG.

  In the present embodiment, the cover 65 includes a first portion 71 and a second portion 72 that is formed thicker than the first portion 71 and reinforces the case 62. According to this, the strength of the case 62 can be ensured more reliably. In particular, the provision of the second portion 72 improves the strength of the case 62 against bending and twisting.

  The second portion 72 is provided below the palm rest 36. According to such a configuration, the palm rest 36 is reinforced by the second portion 72. Thereby, the palm rest 36 becomes difficult to bend.

  In the present embodiment, the cover 65 has a third portion 73 that covers at least a part of the protection circuit 91, is thicker than the first portion 71, and reinforces the case 62. This further improves the strength of the case 62 against bending and twisting.

  In the present embodiment, the second portion 72 and the third portion 73 of the cover 65 are separately located on both sides of the first portion 71 of the cover 65. According to such a configuration, the case 62 is more effectively reinforced by the second portion 72 and the third portion 73.

  In the present embodiment, the frame 81 and the beam 82 are integrally formed of a plastic material. According to such a configuration, it is possible to improve the manufacturability, handleability, manufacturing cost, and the like of the case 62.

  In the present embodiment, the plurality of battery cells 61 and the circuit board 6 partially overlap in a direction intersecting with the thickness direction of the housing 4. According to such a configuration, the casing 4 can be further reduced in thickness. In the present embodiment, the second portion 72 of the cover 65 extends in the longitudinal direction of the circuit board 6. According to such a configuration, the circuit board 6 can be reinforced in the longitudinal direction.
