[Technical Field]
[0001] The present disclosure relates to a cover member mounting structure on a rear surface of a housing of a display device, and the display device. [Background technology]
[0002] Patent Document 1 discloses a mounting structure for components such as speakers in a display device (such as a television). In the structure of Patent Document 1, a plate-shaped member on which the components are mounted is attached to the back of the display device's housing, and this plate-shaped member is covered with a cover member. The cover member is attached to the plate-shaped member with screws or the like. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Publication No. 2022-168659 Summary of the Invention [Problem to be solved by the invention]
[0004] In the structure of Patent Document 1, the cover member is fixed only to the plate-like member, not to the housing member of the display device, which causes a gap to easily form between the cover member and the housing member, detracting from the aesthetic appearance of the display device.
[0005] The present disclosure has been made in consideration of the above-mentioned problems, and aims to provide a cover member mounting structure and a display device that can eliminate a gap between a cover member and a housing member. [Means for solving the problem]
[0006] In order to solve the above problems, the cover member mounting structure of a first aspect of the present disclosure includes a rear housing of a display device, a fixing member fixed to the rear side of the rear housing, and a cover member arranged on the rear side of the rear housing to cover the fixing member, and is characterized in that a portion of the cover member is not fixed to the rear housing but contacts the rear side of the rear housing, and is subjected to a urging force toward the rear housing by the fixing member abutting from the rear side.
[0007] According to the above configuration, even if a part of the cover member is not fixed to the rear housing, the cover member at that point can be pressed against the rear housing by the spring force from the fixing member, thereby eliminating the gap between the rear housing and the cover member.
[0008] Furthermore, in the above-described cover member mounting structure, the fixing member can be configured to have a base, a component fixing portion formed to extend upward from the base and to which a component is attached, a cover pressing portion formed to extend upward from the base and abutting against the cover member to apply the biasing force, and a slit that separates the component fixing portion from the cover pressing portion.
[0009] According to the above configuration, the component fixing portion and the cover pressing portion are separated by the slit, and deformation of the cover pressing portion caused by contact with the cover member can be prevented from being transmitted to the component fixing portion, thereby ensuring positional accuracy of the component on the component fixing portion.
[0010] Furthermore, the cover member mounting structure may be configured such that the component is a speaker, and the speaker is fixed by the component fixing portion so that a sound hole of the speaker faces upward.
[0011] Furthermore, in the above-described cover member mounting structure, the component fixing portion can be configured to be fixed with its front surface in contact with the rear housing, or to be configured to be in contact with the rear housing with its front surface biased toward it.
[0012] According to the above configuration, chattering in the component fixing portion can be suppressed.
[0013] The cover member mounting structure may be configured such that the cover pressing portion has a reinforcing portion formed by drawing.
[0014] According to the above configuration, the strength of the cover pressing portion is increased, and it becomes easier to obtain a large biasing force on the cover member.
[0015] In the cover member mounting structure, the slit may have a width greater at the inner end than at other portions.
[0016] According to the above configuration, stress concentration at the ends of the slit is alleviated, making it possible to make it difficult for stress caused by deformation of the cover pressing portion to be transmitted to the component fixing portion.
[0017] Furthermore, in the above-described cover member mounting structure, the cover member has a protruding portion that protrudes from the outer edge along the back surface of the rear housing, and the fixing member can be configured to abut against the protruding portion to apply the urging force.
[0018] A display device according to a second aspect of the present disclosure comprises a display unit having a rear housing on the opposite side of the display surface, a fixed member fixed to the rear side of the rear housing, and a cover member arranged on the rear side of the rear housing to cover the fixed member, wherein a portion of the cover member is not fixed to the rear housing but contacts the rear side of the rear housing, and is subjected to a biasing force toward the rear housing by the fixed member abutting from the rear side. [Effects of the Invention]
[0019] The cover member mounting structure and display device of the present disclosure have the effect of eliminating the gap between the rear housing and the cover member, thereby preventing the aesthetic appearance of the display device from being impaired by this gap.

DETAILED DESCRIPTION OF THE INVENTION
[0021] [First embodiment] An embodiment of the present disclosure will be described in detail below with reference to the drawings. Fig. 1 is a perspective view of a display device according to the present disclosure as viewed from the rear side. Fig. 2 is a rear view showing a cover member mounting structure (hereinafter referred to as the present mounting structure) that is part of the display device according to this embodiment. Fig. 3 is an exploded perspective view of the present mounting structure. Note that Figs. 2 and 3 only show approximately the right half of the rear surface of the display device, but the display device has an approximately symmetrical structure, and the left half of the rear surface of the display device also has a similar configuration.
[0022] 1 to 3, the display device of this embodiment has a rear housing 10, and a fixing member 11, a speaker 12, and an SP cover (cover member) 13 are attached to the rear side of the rear housing 10. That is, this attachment structure is made up of the rear housing 10, the fixing member 11, the speaker 12, and the SP cover 13. Note that in FIG. 1, the rear housing 10 and the SP cover 13 are shown in a see-through state so that the arrangement of the fixing member 11 and the speaker 12 can be seen.
[0023] The rear housing 10 is a housing member that constitutes the rear surface of the display device main body, and a display panel, a front housing, etc. are arranged on the front side of the rear housing 10. However, since known configurations can be adopted for the display panel and the front housing, in this embodiment, illustrations and detailed descriptions of the configuration on the front side of the rear housing 10 are omitted.
[0024] In a display device, some components may be arranged outside the housing (specifically, on the back side of the rear housing 10). In this embodiment, the speaker 12 is exemplified as such a component, but the type of component arranged outside the housing is not particularly limited. However, since the direction from which sound is emitted is important for the speaker 12, it is preferable that the speaker 12 be attached in a state where it is accurately positioned relative to the display device so that the direction does not change, and the configuration of the present disclosure can be suitably used for this purpose.
[0025] The speaker 12 is fixed to the fixing member 11. At this time, the speaker 12 is fixed to the fixing member 11 so that the sound hole faces upward. The fixing member 11 is fixed to the rear housing 10. In this embodiment, the fixing member 11 is fixed to the rear housing 10 by fastening screws 20. The SP cover 13 is arranged further back than the fixing member 11 and the speaker 12 so as to cover these members.
[0026] As shown in FIG. 3 , the SP cover 13 has an upper surface portion 131 and a rear surface portion 132. The upper surface portion 131 is positioned above the speaker 12, and the front end surface of the upper surface portion 131 is arranged so as to contact the rear surface of the rear housing 10. An opening (not shown) is formed in the upper surface portion 131 at a position facing the speaker 12, through which sound output from the speaker 12 is emitted. In this case, the rear surface portion 132 is arranged so as to cover the fixing member 11 and the speaker 12 from the rear side. Note that the rear surface portion 132 is not shown in FIG. 2 so that the fixing member 11 and the speaker 12 can be seen. The SP cover 13 may be a single component in which the upper surface portion 131 and the rear surface portion 132 are integrally formed, or may be an assembled component in which the upper surface portion 131 and the rear surface portion 132 are separate components.
[0027] In this mounting structure, the vicinity of the lower end of SP cover 13 is mounted to rear housing 10. As a specific example, boss 101 having screw hole 101a is provided on the rear surface of rear housing 10, and the vicinity of the lower end of SP cover 13 is fixed to rear housing 10 by fastening screws 21 into screw hole 101a from the rear surface side. However, in this mounting structure, the vicinity of the lower end of SP cover 13 is not limited to being mounted to rear housing 10, and may be mounted to fixing member 11.
[0028] On the other hand, in this mounting structure, the vicinity of the upper end of SP cover 13 is not particularly fixed to rear housing 10. Therefore, this mounting structure has a structure to prevent a gap from occurring between upper surface portion 131 of SP cover 13 and rear housing 10. This structure will be described below.
[0029] Fig. 4 is a rear view of the fixing member 11. Fig. 5 is a rear view of the upper surface portion 131 of the SP cover 13. Fig. 6 is a partial cross-sectional view of the mounting structure in Fig. 2 (cross-sectional view taken along line AA in Fig. 2).
[0030] As shown in Fig. 4, the fixing member 11 is a substantially rectangular plate-like member having a slit 111 cut from the upper edge. In the fixing member 11, an SP fixing portion (component fixing portion) 112 and a cover pressing portion 113 are provided with the slit 111 sandwiched therebetween, and the lower portions of the slit 111, the SP fixing portion 112, and the cover pressing portion 113 are all connected to a base 114. That is, the SP fixing portion 112 and the cover pressing portion 113 are both formed to extend upward from the base 114. The slit 111 separates the SP fixing portion 112 and the cover pressing portion 113 from each other. The fixing member 11 is fixed to the rear housing 10 mainly by fastening the base 114 with screws.
[0031] Speaker 12 is attached to the tip (top end) of SP fixing portion 112. There are no particular limitations on the method for fixing speaker 12 to SP fixing portion 112, and methods such as screwing, push rivets, and double-sided tape can be used. Cover pressing portion 113 abuts its tip (top end) against SP cover 13 from the rear side, and acts as a leaf spring to apply a biasing force to SP cover 13 forward (i.e., toward rear housing 10).
[0032] As shown in FIG. 5, the top surface 131 of the SP cover 13 has a protruding portion 131a that protrudes downward. As shown in FIG. 6, in this embodiment, the protruding portion 131a is arranged so as to be inserted between the rear housing 10 and the cover pressing portion 113 of the fixed member 11. This allows the SP cover 13 to receive the biasing force F from the cover pressing portion 113 via the protruding portion 131a, and allows the front end surface of the top surface 131 to contact the rear housing 10 without any gap. Note that the fixed member 11 may be provided with a drawn portion (reinforcement portion) 115 to improve the strength of the cover pressing portion 113 so that the biasing force F from the cover pressing portion 113 can be sufficiently obtained. The drawn portion 115 is an uneven portion formed on the fixed member 11 by drawing. The shape and number of the drawn portion 115 are not particularly limited, but are basically formed in the area of the cover pressing portion 113. However, the drawn portion 115 may be formed across the areas of the cover pressing portion 113 and the base 114.
[0033] 6, the tip of the cover retainer 113 may be inclined so that the upper end faces rearward. This facilitates attachment of the SP cover 13 during assembly of this mounting structure. Specifically, with the fixing member 11 fixed to the rear housing 10, the SP cover 13 is positioned so that the protrusion 131a is inserted from above between the rear housing 10 and the cover retainer 113. At this time, the inclination of the tip of the cover retainer 113 toward the rear facilitates insertion of the protrusion 131a. After the SP cover 13 is positioned as described above, the SP cover 13 is fixed by fastening the screw 21 into the screw hole 101a of the boss 101.
[0034] As described above, in this mounting structure, a part of SP cover 13 (for example, protrusion 131a) abuts against fixed member 11 on the front side, and receives a biasing force F toward rear housing 10 due to the abutment with fixed member 11. As a result, even if a part of SP cover 13 is not fixed to rear housing 10, that part receives biasing force F from fixed member 11 and is pressed against rear housing 10, and it is possible to eliminate a gap between rear housing 10 and SP cover 13.
[0035] When cover retainer 113 acts as a leaf spring and applies biasing force F to SP cover 13, deformation occurs in cover retainer 113. If this deformation is transmitted from cover retainer 113 to SP fixing portion 112, the positional accuracy of speaker 12 attached to SP fixing portion 112 will decrease, and there is a risk that speaker 12 will not be able to perform as designed. In response to this, in this mounting structure, slit 111 is provided between SP fixing portion 112 and cover retainer 113, and slit 111 prevents deformation occurring in cover retainer 113 from being transmitted to SP fixing portion 112. This ensures high positional accuracy for speaker 12 attached to SP fixing portion 112 (the orientation of speaker 12 does not change when SP cover 13 is attached), allowing speaker 12 to perform as designed.
[0036] Furthermore, in fixing member 11, the biasing force F generated by cover pressing portion 113 can be adjusted by adjusting the position and depth of slit 111. For example, in fixing member 11 shown in FIG. 4, the lower side of slit 111 is inclined with respect to the vertical direction, thereby widening the width of cover pressing portion 113 on the base side (near base 114) and widening the width of SP fixing portion 112 on the tip side (opposite base 114). In this case, the wide width of cover pressing portion 113 on the base side makes it easier to generate a large biasing force F. On the other hand, the width of SP fixing portion 112 on the tip side ensures a sufficient mounting area for speaker 12.
[0037] 4, the lower end of slit 111 is inclined toward SP fixing portion 112, and therefore, when deformation occurs in cover pressing portion 113, the stress is directed toward SP fixing portion 112, making it easy for stress to concentrate at the lower end of slit 111. In contrast, in fixing member 11 of FIG. 4, by providing wide portion 111a at the lower end of slit 111 (i.e., the end portion on the inner side of the notch), stress concentration at the lower end of slit 111 is suppressed, and stress due to deformation of cover pressing portion 113 is less likely to be transmitted to SP fixing portion 112.
[0038] Furthermore, it is preferable that measures be taken to prevent chatter caused by vibration for the SP fixing portion 112 to which the speaker 12 is attached. One example of such measures is to adhere a partial area (e.g., area R in FIG. 4 ) of the surface of the SP fixing portion 112 facing the rear housing 10 to the rear housing 10 with double-sided tape or the like. This adherence firmly fixes the SP fixing portion 112 to the rear housing 10, thereby preventing chatter of the SP fixing portion 112. Another example of a chatter prevention measure is to provide the SP fixing portion 112 with the function of a leaf spring, and use the biasing force of the leaf spring to press the SP fixing portion 112 firmly against the rear housing 10. In this way, pressing the SP fixing portion 112 firmly against the rear housing 10 also serves as a chatter prevention measure for the SP fixing portion 112.
[0039] Second Embodiment FIG. 7 is a rear view showing the mounting structure according to the second embodiment. In the example shown in FIG. 7, the slits 111 are formed parallel to the vertical direction. If a particularly large biasing force F is not required in the cover pressing portion 113, forming the slits 111 parallel to the vertical direction does not pose any particular problem even if the width of the base side of the cover pressing portion 113 is not widened. On the other hand, in the example shown in FIG. 7, forming the slits 111 parallel to the vertical direction makes it difficult for stress due to deformation of the cover pressing portion 113 to be directed toward the SP fixing portion 112. In other words, even if the cover pressing portion 113 of the fixing member 11 deforms in this mounting structure, it does not affect the SP fixing portion 112.
[0040] Third Embodiment Fig. 8 is a rear view showing the mounting structure according to the third embodiment. The example shown in Fig. 8 is a shape suitable for cases where a larger biasing force F is required from the cover retainer 113. In this example, the lower end of the slit 111 is positioned outside (on the SP fixing portion 112 side) of at least one screw 20. This allows the lower end of the cover retainer 113 to be formed wider, and the lower end of the cover retainer 113 is firmly fixed to the rear housing 10 by the screw 20, allowing the biasing force F from the cover retainer 113 to be increased.
[0041] [Fourth embodiment] 9 is a rear view showing the mounting structure according to the fourth embodiment. The example shown in FIG. 9 is a shape suitable for applying the biasing force F to the SP cover 13 over a wider range. In this example, the cover pressing portion 113 is formed in a substantially U-shape (inverted U-shape) so as to surround the SP fixing portion 112. That is, the two sides of the cover pressing portion 113 that act as leaf springs are arranged on both sides of the SP fixing portion 112 in the left-right direction, and the upper side of the cover pressing portion 113 can apply the biasing force F to the SP cover 13 over a wider range. In this case, the slit 111 is also formed in a substantially U-shape so as to surround the SP fixing portion 112.
[0042] In this case, the SP cover 13 may have a plurality of protrusions 131a formed along the left-right direction, and the upper side of the cover pressing part 113 may simultaneously apply the urging force F to these plurality of protrusions 131a. Alternatively, the protrusions 131a on the SP cover 13 may be formed in the shape of a rib that is wide in the left-right direction.
[0043] Fifth Embodiment Fig. 10 is a plan view showing the fixing member 11 in the fifth embodiment. Note that, although two fixing members 11, which are symmetrical to each other, are used in the display device in this embodiment, Fig. 10 shows only one of the fixing members 11 (the right side when viewed from the back side of the display device).
[0044] The fixing member 11 in Fig. 10 has a shallower slit 111 (shorter in the vertical direction) than those in the first to fourth embodiments. The fixing member 11 is basically attached to the rear housing 10 with screws 20 (see Fig. 3), but double-sided tape may also be used in combination to strengthen the biasing force of the cover pressing portion 113. That is, the fixing member 11 in Fig. 10 has a shallower slit 111, and by adhering the lower region of the cover pressing portion 113 (for example, the region enclosed by the dashed line in Fig. 10) to the rear housing 10 with double-sided tape, it is possible to ensure a strong biasing force at the cover pressing portion 113.
[0045] The embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. Therefore, the technical scope of the present disclosure should not be interpreted solely by the above-described embodiments, but should be determined based on the claims. [Explanation of symbols]
