Description

Technical Field

[0001] The invention relates to peripheral products of computer equipment, in particular to an electronic mouse with a palm rest having a backlight effect. Background Art

[0002] Electronic mouse is a common peripheral product of computer equipment. With the development of society and the advancement of science and technology, users of electronic mouse pay more and more attention to the design that can relieve user fatigue. In order to relieve the wrist pain or soreness that users may experience when using electronic mouse for a long time, the prior art proposes an electronic mouse with a detachable palm rest. Since the mouse palm rest is arranged at the rear end of the mouse body, and when the electronic mouse is normally stationary, the mouse palm rest is usually on the side close to the user and has a surface facing the user.

[0054] DETAILED DESCRIPTION

[0055] Please refer to Figure 1-Figure 8 , Fig.11 , Fig.17 and Fig.18 In one embodiment, the electronic mouse with a palm rest having a backlight effect of the present invention comprises a mouse body 100 and a mouse palm rest 200 detachably connected to the mouse body 100;

[0056] The mouse body 100 includes a shell 10 and a backlight assembly 20. The rear end of the shell 10 has a first adjacent surface 11 adjacent to the mouse palm rest 200. The first adjacent surface 11 is provided with a light-transmitting area 12. The backlight assembly 20 is provided in a cavity 13 of the shell 10 corresponding to the light-transmitting area 12.

[0057] The housing 10 includes an upper shell 14 and a lower shell 15 . The upper shell 14 and the lower shell 15 are covered and enclosed in the up-down direction to form a cavity 13 . The first adjacent surface 11 is formed on the lower shell 15 .

[0058] The backlight source assembly 20 includes a lamp bead 22 and a lampshade 23 sleeved on the periphery of the lamp bead 22. The light-transmitting area 12 is a through hole opened in the lower shell 15. The lampshade 23 is installed in the through hole of the light-transmitting area 12 with its opening facing inward. The inner cavity of the lampshade 23 is provided with a light-scattering structure 231 on the bottom surface away from the opening.

[0059] The mouse palm rest 200 includes a palm rest body 30, which has a second adjacent surface 321 opposite to the first adjacent surface 11, and a light receiving area 322 corresponding to the light transmitting area 12 is provided on the second adjacent surface 321; a backlight area 311 is provided on the rear side of the palm rest body 30; the palm rest body 30 includes a base 31 and an upper cover 32, and the upper cover 32 and the base 31 are covered in the up and down directions; the second adjacent surface 321 is formed on the upper cover 32; the light emitted by the backlight source assembly 20 is projected to the backlight area 311 through the light transmitting area 12 and the light receiving area 322 in sequence.

[0060] In this embodiment, the housing 10 provides a storage space for multiple parts and supports the main body. The housing 10 is usually assembled from multiple parts. Since there are many functions to be satisfied, the shape of the housing 10 is also relatively complex, so its main structure preferably adopts an injection molding process. By setting the housing 10 to a structure that opens and closes up and down, it is convenient to install the backlight source assembly 20 in the cavity 13 of the housing 10 and use the housing 10 to provide protection for the backlight source assembly 20. Since the lower shell 15 has a surface closer to the palm rest 30 relative to the upper shell 14, it can provide more design space for selecting a suitable light-transmitting area 12 and the orientation of the light-transmitting area 12.

[0061] The lamp beads 22 are preferably LED lamp beads, which have high brightness and long life. Figure 6 Figure 9 to Fig.16 In one embodiment, in order to allow a sufficient and uniform amount of light to pass through the backlight area 311, a lampshade 23 with a light-scattering structure 231 is provided. The light-scattering structure 231 may be a striped structure, or a concave-convex array structure, etc., as long as it is convenient for light to be scattered. After the light passes through the light-scattering structure 231 and then passes through the light-receiving area 322, a more complex light propagation path can be formed in the palm rest 30, thereby achieving a better light mixing effect in the palm rest 30, and the light transmitted through the backlight area 311 is also softer. In addition to the light-scattering effect, the lampshade 23 can also provide additional and more local protection for the lamp beads 22. By providing the light-scattering structure 231 on an independent component, namely the lampshade 23, it is helpful to reduce the manufacturing difficulty compared to directly providing it on the housing 10.

[0062] In order to realize the detachable connection between the mouse body 100 and the mouse palm rest 200, an existing detachable connection method can be adopted, such as a simple snap connection or a magnetic connection. The electronic mouse adopts a combination of magnetic attraction and snap connection. Specifically, the rear end of the shell 10 also has a third splicing surface, the mouse body 100 also includes a first magnetic member arranged corresponding to the third splicing surface, and the shell 10 is also provided with an anti-slip snap connection structure; the palm rest is also provided with a fourth splicing surface facing forward, and the mouse palm rest 200 also includes a second magnetic member arranged corresponding to the fourth splicing surface. The attraction between the first magnetic member and the second magnetic member keeps the first adjacent surface 11 in contact with the second adjacent surface 321. The anti-slip matching structure snaps with the anti-slip snap connection structure along an inclined direction, and the anti-slip matching structure and the anti-slip snap connection structure are double-sidedly limited in a vertical direction perpendicular to the inclined direction and parallel to the longitudinal vertical surface, and the inclined direction has forward and upward components. The clamping connection between the anti-dropping clamping structure and the anti-dropping matching structure is a connection model of the matching between a protrusion and a groove. The anti-dropping clamping structure can be either a protrusion or a groove, and the anti-dropping matching structure can be a groove and a protrusion accordingly.

[0063] The first adjacent surface 11 and the second adjacent surface 321 are arranged opposite to each other or fit each other, so that they are complementary in shape. The first adjacent surface 11 can be a simple plane, a curved surface or a bent surface. The light-transmitting area 12, the light-receiving area 322 and the backlight area 311 can be a thin-walled structure made of a light-transmitting material, or can be a through hole. For example, the housing 10 partially uses a light-transmitting material in the light-transmitting area 12, or the housing 10 forms a through hole in the light-transmitting area 12. That is, as long as it is convenient for light to pass through in sequence.

[0064] The electronic mouse with a palm rest having a backlight effect of the present invention is provided with a light-transmitting area 12 and a light-receiving area 322 at the joint position of the shell 10 of the mouse body 100 and the palm rest body 30 of the mouse palm rest 200, respectively, so that the light emitted by the backlight source assembly 20 arranged in the housing 13 of the shell 10 can be transmitted from the shell 10 to the inside of the palm rest body 30, and further transmitted through the backlight area 311 to the outside of the palm rest body 30 to achieve the backlight effect. Specifically, the backlight source assembly 20 is provided with a lampshade 23 sleeved on the lamp bead 22, and the bottom surface of the lampshade 23 is provided with a light-scattering structure 231, so that the angle of the light emitted by the backlight source assembly 20 is relatively divergent, so that after passing through the light-transmitting area 12 and the light-receiving area 322 in turn, it can be fully mixed inside the palm rest body 30, so that the light emitted by the backlight source assembly 20 is transmitted to the backlight area 311 as much as possible and evenly, and then the backlight effect with moderate and even backlight intensity is obtained in the backlight area 311. In the above solution, it is not necessary to set an energy receiving device or a battery device in the palm rest 30, because the backlight assembly 20 can use the original energy receiving device of the mouse body 100, such as the main circuit structure; or the original battery device to receive electric energy to emit light. Therefore, the cost of realizing the backlight effect on the detachable palm rest of the electronic mouse of the present invention is low, and the corresponding components or structures are light in weight, so it has better practicality and is more conducive to market promotion.

[0065] Please also refer to Fig. 9 In one embodiment, the housing 10 includes an upper shell 14 and a lower shell 15, the upper shell 14 and the lower shell 15 are covered and enclosed in the up and down direction to form a cavity 13, and the first adjacent surface 11 is formed on the lower shell 15; the backlight assembly 20 includes a circuit board 21 and lamp beads 22, the circuit board 21 is fixedly installed on the inner wall surface of the lower shell 15 corresponding to the light-transmitting area 12, and the lamp beads 22 are installed on the side of the circuit board 21 facing the light-transmitting area 12. In this embodiment, the backlight assembly 20 is convenient for installation through the circuit board 21, on the one hand, and it is convenient to design a driving and control circuit for driving the lamp beads 22 on the circuit board 21, for example, turning off or turning on the lamp beads 22, controlling the LED light intensity and color, and achieving a set light effect, such as a breathing light effect. The lamp beads 22 have strong brightness and long life, and the material cost is low. The use of lamp beads 22 can achieve a better backlight effect and ensure a lower manufacturing cost.

[0066] Furthermore, the first adjacent surface 11 is fitted with the second adjacent surface 321 , and one end of the lampshade 23 away from the circuit board 21 protrudes out of the first adjacent surface 11 . A positioning groove 323 adapted to the lampshade 23 is provided at the light receiving area 322 .

[0067] In this embodiment, if the lampshade 23 is recessed relative to the first adjacent surface 11 or is flush with the first adjacent surface 11, then when the first adjacent surface 11 and the second adjacent surface 321 are not closely fitted, that is, when a gap is formed between the two, the light emitted by the backlight source assembly 20 may leak from the gap, that is, light leakage outside the design occurs. However, by providing a positioning groove 323 at the light receiving area 322 and embedding the protruding end of the lampshade 23 into the positioning groove 323, it is not only convenient for the light-transmitting area 12 to accurately align with the light receiving area 322, but also can achieve the effect of preventing light leakage.

[0068] Furthermore, the first adjacent surface 11 is tilted upward from front to back, and the palm rest 30 is located between the extended surface of the bottom surface of the housing 10 and the first adjacent surface 11 ; the lower end surface of the lampshade 23 is parallel to the first adjacent surface 11 .

[0069] In this embodiment, it is understandable that if the first adjacent surface 11 is adjacent to the bottom surface of the housing 10 and is arranged backward, it is also convenient to arrange the light-transmitting area 12 to transmit light to the palm rest 30. However, since the bottom of the electronic mouse is generally provided with light-sensing electronic devices, main circuit structures, or the first magnetic member and the second magnetic member as mentioned in the previous embodiment, in other words, the design space of this part is relatively tight. By arranging the first adjacent surface 11 and the bottom extension surface of the housing 10 relative to each other, the installation space of the backlight source assembly 20 can be transferred to the relatively upper part of the housing 10, thereby reducing the difficulty of designing and assembling the electronic mouse.

[0070] Further, please refer again to Figure 5 , Figure 6 as well as Figures 9 to 14 In one embodiment, the lower shell 15 includes a bottom wall 151, a first rear side wall 152 and a second rear side wall 153, the first rear side wall 152 is connected to the rear end of the bottom wall 151, and the second rear side wall 153 is connected to the upper end of the first rear side wall 152; the second rear side wall 153 has a uniform wall thickness, and the second rear side wall 153 is tilted upward from the front to the back from the upper end of the first rear side wall 152; the backlight source assembly 20 includes two pairs of lamp beads 22 and lamp covers 23, the two pairs of lamp beads 22 and lamp covers 23 are arranged at intervals in the left and right directions, and the first adjacent surface 11 is provided with two light-transmitting areas 12 corresponding to the two lamp covers 23.

[0071] In this embodiment, the second rear side wall 153 is connected to the bottom wall 151 through the first rear side wall 152, so that a larger accommodating space can be formed below the second rear side wall 153. The lower shell 15 forms the first adjacent surface 11 through the second rear side wall 153 with uniform wall thickness, which is conducive to ensuring the lightweight structure of the lower shell 15. By arranging two lamp beads 22 spaced apart from each other, a backlight effect with sufficient brightness and uniformity can be achieved through the lamp beads 22 with relatively low power. It can be understood that although the present embodiment limits the number of lamp beads 22 to two, the same effect can be achieved by arranging more than two.

[0072] Furthermore, the inner wall surface of the second rear side wall 153 extends upward at the edge of the light-transmitting area 12 to form a support tube 154, and the second rear side wall 153 is also provided with a support plate 155 between the two support tubes 154; the backlight source assembly 20 also includes a connecting plate 24 connecting the two lampshades 23 and integrally arranged with the lampshades 23, the connecting plate 24 has a flange portion 241 protruding from the outer peripheral surface of the lampshade 23, the connecting plate 24 is horizontally arranged and fits the side of the circuit board 21 facing the light-transmitting area 12, the flange portion 241 is mounted on the upper end surface of the support tube 154, and the middle section of the connecting plate 24 is mounted on the upper side surface of the support plate 155.

[0073] In this embodiment, in order to quickly assemble the two lampshades 23, the two lampshades 23 are connected together by the connecting plate 24, which not only reduces the number of parts, but also facilitates the manufacture of the lampshades 23 themselves. For example, the lampshades 23 are manufactured by injection molding, and the injection plastic can flow from the mold cavity of one lampshade 23 into the mold cavity of another lampshade 23. The support plate 155 abuts against the middle section of the supporting connecting plate 24, and the support tube 154 is used to support the flanges 241 at both ends of the connecting plate 24, so that the positions of the two lampshades 23 can be ensured in a combined assembly. The connecting plate 24 is arranged horizontally, and the circuit board 21 attached to the connecting plate 24 is also arranged horizontally, so that the connecting plate 24 and the circuit board 21 can be conveniently clamped horizontally to be quickly assembled to the lower shell 15.

[0074] Further, please refer again to Figures 11 to 16 In one embodiment, positioning slots 242 are respectively provided at the front and rear edges of the connecting plate 24 , and a positioning rib 156 adapted to the positioning slots 242 is protruded upward on the inner wall surface of the second rear side wall 153 .

[0075] In this embodiment, the positioning slots 242 on the connecting plate 24 cooperate with the positioning ribs 156 to prevent the connecting plate 24 from being misplaced or shaken in the left-right direction, and reduce the reliance on the cooperation between the lampshade 23 and the inner wall of the support tube 154 to ensure the position accuracy of the lampshade 23 in the left-right direction.

[0076] Furthermore, the support plate 155 is connected to at least one of the support tubes 154 , and the two positioning ribs 156 are connected to the front side and the rear side of the support plate 155 , respectively.

[0077] In this embodiment, the support plate 155 is connected to the support tube 154 and the positioning ribs 156, which can not only enhance its own strength, but also enhance the strength of the corresponding support tube 154 and the two positioning ribs 156 to reduce deformation, thereby further ensuring the accuracy of the assembly of the lampshade 23.

[0078] Furthermore, the inner wall surface of the second rear side wall 153 is provided with positioning columns 157 and screw hole columns 158 spaced apart along the left-right direction, and the circuit board 21 is provided with a positioning hole 211 adapted to the positioning column 157, and an open semicircular hole 212 is provided at the edge of the circuit board 21 corresponding to the screw hole column 158, and the aperture of the positioning hole 211 is smaller than the aperture of the semicircular hole 212; the backlight source assembly 20 also includes a fastener 25, which cooperates with the screw hole of the screw hole column 158 and tightens the edge of the semicircular hole 212 downward.

[0079] In this embodiment, the positioning column 157 cooperates with the fastener 25 to reduce the number of fasteners 25, while ensuring the accuracy of the installation position of the circuit board 21. By opening the semicircular hole 212 with a larger aperture at the edge of the circuit board 21, the influence of the fastening structure on the internal circuit wiring of the circuit board 21 can be reduced, that is, the flexibility of the internal circuit wiring of the circuit board 21 can be improved. In the example where the backlight assembly 20 is provided with a connecting plate 24, by fastening the circuit board 21, the connecting plate 24 is also fastened together, thereby improving the compactness of the structure.

[0080] For further information, please refer to Figures 2 to 8 ,as well as Fig.17 and Fig.18 In one embodiment, the light receiving area 322 is a through hole opened in the upper cover 32 ; the mouse palm rest 200 also includes a diffuser plate 40 covering the light receiving area 322 from the inner side of the upper cover 32 .

[0081] In this embodiment, similar to the installation of the backlight assembly 20, the installation of the diffuser plate 40 can be facilitated by providing the palm rest 30 with a base 31 and an upper cover 32 that cover each other. The diffuser plate 40 can further enhance the effect of diffusing the light from the light source, thereby achieving a better light mixing effect inside the palm rest 30. In the embodiment in which the front light receiving area 322 forms a positioning groove 323, the diffuser plate 40 can be used to form the bottom surface of the positioning groove 323. In addition, the diffuser plate 40 covering the light receiving area 322 can also prevent dust from entering the palm rest 30.

[0082] Please also refer to Fig. 20In one embodiment, the upper cover 32 includes a top wall 324, the second adjacent surface 321 is formed on the top wall 324, and the inner wall surface of the top wall 324 is provided with a clamping column 325 extending downward; the bottom wall surface of the base 31 is provided with a limiting column 312 extending upward, and the diffuser plate 40 is provided with a clamping hole 41 adapted to the clamping column 325, and the lower surface of the diffuser plate 40 abuts against the upper end surface of the limiting column 312.

[0083] In this embodiment, the clamping column 325 cooperates with the clamping hole 41 on the diffuser plate 40 to fix the diffuser plate 40 relative to the upper cover 32 by utilizing the elastic force of the clamping. When the upper cover 32 and the base 31 are covered, under the abutment of the limiting column 312, the diffuser plate 40 can gradually slide to the correct position, that is, the diffuser plate 40 is also assembled in place by the upper cover 32 and the base 31 being covered in place, thereby improving the convenience of assembly. It can be understood that in order to increase the contact area and facilitate injection molding at the same time, the limiting column 312 is in a hollow tubular shape. When the diffuser plate 40 is tilted, the upper end surface of the limiting column 312 can be set to an inclined annular surface that fits the lower surface of the diffuser plate 40.

[0084] Furthermore, the upper cover 32 also includes a circumferential side wall 326 connected to the edge of the top wall 324 and extending downward, and the circumferential side wall 326 abuts against the bottom wall surface of the base 31 , and a closed chamber 33 is enclosed between the upper cover 32 and the base 31 .

[0085] In this embodiment, the upper cover 32 and the base 31 enclose a closed chamber 33 , which can prevent light from leaking out from undesigned locations, that is, avoid the formation of stray light that affects the light effect.

[0086] For further information, please refer to Figures 18 to 20 In one embodiment, a rear panel 313 extending upward is provided at the rear end of the base 31, a backlight area 311 is formed on the rear panel 313, and a through hole penetrating the rear panel 313 is formed at the backlight area 311; the mouse palm rest 200 also includes a light guide 50 covering the backlight area 311 from the inner side of the base 31.

[0087] In this embodiment, the light receiving area 322 and the backlight area 311 are respectively formed on the detachable upper cover 32 and the base 31. Compared with being formed on a single component, the shape complexity of the single component is correspondingly reduced, thereby reducing the manufacturing difficulty. By setting the light guide 50, the light received by the light guide 50 can be propagated inside the light guide 50, and further guide the light to pass through the backlight area 311. It can be understood that in order to promote more light to enter the light guide 50, the size of the light guide 50 can be set to be larger than the backlight area 311, for example, a shape that is adapted to the shape of the inner wall surface of the rear panel 313 and is similar in size; in addition, the light guide 50 can form a curved surface that is roughly facing the diffuser 40. The light guide 50 can be either a transparent component or a colored light-transmitting component, such as a red light-transmitting component, so that when white light passes through the light guide 50, the light guide 50 can present a red backlight effect.

[0088] Furthermore, two backlight areas 311 are provided on the rear panel 313, and the two backlight areas 311 are arranged at intervals in the left-right direction; the inner wall surface of the top wall 324 is provided with a snap-in ridge 327 adjacent to the rear edge, and the rear panel 313 is provided with two snap-in ribs 314 extending upward, and the two snap-in ribs 314 are arranged at intervals in the left-right direction, and the two snap-in ribs 314 are located between the two backlight areas 311; the upper end of the snap-in rib 314 is provided with a snap-in groove 314a adapted to the snap-in ridge 327; the light guide 50 is a thin-walled structure that fits the inner wall surface of the rear panel 313, the light guide 50 covers the two backlight areas 311, and the light guide 50 has a avoidance recess 51 that semi-surrounds the snap-in rib 314.

[0089] In this embodiment, two backlight areas 311 are provided on the rear panel 313, so that the backlight effect of the light guide 50 can be observed from a wider angle range. Two clamping ribs 314 are arranged between the two backlight areas 311 at intervals on the left and right and relatively centered, so that the clamping convex strip 327 cooperates with the clamping groove 314a to enhance the stability of the clamping of the upper cover 32 and the base 31. The avoidance recess 51 of the light guide 50 cooperates with the clamping rib 314, which can not only preliminarily position the light guide 50, but also ensure that one light guide 50 covers the two backlight areas 311 at the same time.

[0090] Furthermore, a pair of front limiting protrusions 315 and side limiting protrusions 316 are respectively provided at the two ends of the bottom wall surface of the base 31 corresponding to the light guide 50, the two front limiting protrusions 315 have rearward limiting surfaces, and the two side limiting protrusions 316 have side limiting surfaces facing each other in the left-right direction;

[0091] The front side surfaces at both ends of the light guide 50 cooperate with the rear limiting surfaces of the front limiting protrusion 315, and the left and right end surfaces of the light guide 50 cooperate with the side limiting surfaces of the two side limiting protrusions 316 respectively;

[0092] The avoidance recess 51 is located in the middle section of the light guide 50 in the left-right direction. The bottom wall surface of the base 31 is further provided with a middle limit protrusion 317 abutting against the front side surface of the avoidance recess 51 .

[0093] In the present embodiment, a pair of front limiting protrusions 315 and side limiting protrusions 316 are respectively provided at the left and right ends of the light guide 50 to prevent the light guide 50 from moving in the left and right directions or moving backwards. Since the light guide 50 needs to cover two backlight areas 311 at the same time, the light guide 50 is in the shape of a long strip in the left and right directions. If the middle section of the light guide 50 is not limited, the light guide 50 may bend backwards due to accumulated deformation. By providing a middle limiting protrusion 317, the middle section of the light guide 50 can be prevented from moving backwards.

[0094] Please also refer to Fig.21 In one embodiment, the rear side of the light guide member 50 has a light guide boss 52 , and the light guide boss 52 extends into the via hole at the backlight area 311 .

[0095] In this embodiment, the light guide boss 52 cooperates with the via hole to at least increase the position limit in the up and down direction. Combined with the position limit scheme described above, the light guide member 50 is more comprehensively limited. In addition to the position limit function, the light guide boss 52 also appropriately increases the light guide length along the inner and outer directions of the rear panel 313 through the outer peripheral surface of the light guide boss 52, thereby achieving a better backlight effect.

[0096] Those skilled in the art will appreciate that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0097] It should be understood that the above-mentioned embodiments are merely illustrative and not restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by those skilled in the art to the above-mentioned details will be included in the scope of the claims of the present invention.
