[0062] DETAILED DESCRIPTION

[0063] Please refer to Figures 1 to 9 In one embodiment, the electronic mouse with a detachable palm rest provided by the present invention comprises a mouse body (100A, 100B) and a mouse palm rest (200A, 200B) detachably connected to the mouse body (100A, 100B);

[0064] The mouse body (100A, 100B) comprises a shell 10 and a first magnetic member 20. The shell 10 has a first joint surface 121 arranged backwards, and the first magnetic member 20 is arranged corresponding to the first joint surface 121. The left and right sides of the shell 10 are respectively provided with anti-dropping clamping structures 12.

[0065] The mouse palm rest (200A, 200B) comprises a palm rest body 50 and a second magnetic member 60, wherein the palm rest body 50 has a second joint surface 51 arranged forward, and the second magnetic member 60 is arranged corresponding to the second joint surface 51; the attraction between the first magnetic member 20 and the second magnetic member 60 keeps the first joint surface 121 in contact with the second joint surface 51;

[0066] The bottom surface of the palm rest 50 is flush with the bottom surface of the shell 10. Anti-slip mating structures 52 are provided on the left and right sides of the palm rest 50. The anti-slip mating structures 52 protrude along an inclined direction so as to be snap-fitted with the corresponding anti-slip snap-fit ​​structures 12. The inclined direction has forward and upward components.

[0067] In this embodiment, the housing 10 provides a storage space and a supporting body for multiple parts. The housing 10 is usually assembled from multiple parts. Since there are many functions to be met, the shape of the housing 10 is also relatively complex, so its main structure preferably adopts an injection molding process. The first magnetic member 20 and the second magnetic member 60 can be a combination of a magnet and a ferromagnetic metal, or a combination of a magnet and a magnet. It is understandable that if an electromagnetic device is used, the same effect can be achieved in function. The first splicing surface 121 and the second splicing surface 51 fit each other, so that they are complementary in shape. The first splicing surface 121 can be a simple plane, a curved surface or a bent surface. In order to simplify the design of the first splicing surface 121 and the first magnetic member 20 associated with the shape of the first splicing surface 121, the first splicing surface 121 is usually designed as a plane. The snap connection between the anti-slipping snap connection structure 12 and the anti-slipping matching structure 52, its connection model is the matching between the protrusion and the groove, the anti-slipping snap connection structure 12 can be either a protrusion or a groove, and the anti-slipping matching structure 52 can be a groove and a protrusion accordingly.

[0068] The electronic mouse with a detachable palm rest of the present invention respectively sets a first magnetic component 20 and a second magnetic component 60 in the mouse body (100A, 100B) and the mouse palm rest (200A, 200B), so that when the electronic mouse is lifted off a supporting surface such as a desktop, the magnetic attraction can keep the first joint surface 121 of the shell 10 in contact with the second joint surface 51 of the palm rest body 50 to maintain the connection between the two, but it is convenient for the user to remove the mouse palm rest (200A, 200B) from the mouse body (100A, 100B) in the direction opposite to the tilting direction. In addition, since the anti-detachment matching structure 52 of the palm rest body 50 is connected to the anti-detachment clamping structure 12 of the shell 10 along an inclined direction with a forward and upward component, and is limited on both sides in a direction perpendicular to the inclined direction and parallel to the longitudinal vertical plane, the corresponding limiting structure can form a self-locking structure with the support surface such as the desktop to prevent the mouse palm rest (200A, 200B) from detaching from the mouse body (100A, 100B), whether the mouse is manipulated forward or dragged backward, thereby ensuring that the mouse palm rest (200A, 200B) is reliably connected to the mouse body (100A, 100B) during use. In summary, the electronic mouse with a detachable palm rest of the present invention is easy to disassemble when lifted off the desktop, and can ensure that the mouse palm rest (200A, 200B) is reliably connected when dragging, thereby having the characteristics of both convenience of use and relief of wrist fatigue.

[0069] For further information, please refer to Figure 10 to Figure 11 In one embodiment, the shell 10 includes an upper shell 13 and a lower shell 14 , and the upper shell 13 and the lower shell 14 are covered and enclosed in the up and down directions to form a cavity 15 . The first magnetic member 20 is disposed in the cavity 15 and fixedly mounted on the inner wall surface of the lower shell 14 .

[0070] In this embodiment, the shell 10 is configured to have an upper and lower opening structure, which facilitates installation of the first magnetic component 20 in the housing cavity 15 of the shell 10 , so that the shell 10 can provide protection for the first magnetic component 20 .

[0071] Further, please refer again to Figure 5 , and also refer to Figures 12 to 15 In one embodiment, the lower shell 14 includes a bottom wall 142 and a rear side wall 141 connected to the rear end of the bottom wall 142, the rear side wall 141 is tilted upward from front to back, the first splicing surface 121 is the outer wall surface of the rear side wall 141, and the first magnetic component 20 is fixedly installed on the inner wall surface of the rear side wall 141.

[0072] In this embodiment, the first joint surface 121 is formed on the rear side wall 141, and the rear side wall 141 is inclined, so the first joint surface 121 is inclined relative to the horizontal vertical surface, so that when the mouse is picked up from the horizontal support surface in the up-down direction, the magnetic attraction between the first magnetic member 20 and the second magnetic member 60 can better resist the influence of gravity. The first magnetic member 20 is installed on the inner side of the rear side wall 141 so that the distance between the first magnetic member 20 and the first joint surface 121 can be reduced as much as possible, thereby reducing the loss of magnetic attraction distance and ensuring sufficient magnetic attraction.

[0073] Further, please refer again to Figure 5 as well as Figures 10 to 15 In one embodiment, the mouse body (100A, 100B) also includes a fixed frame 30 and a limiting pressure plate 40, the fixed frame 30 includes a front frame plate 31 and an upper frame plate 32, the front frame plate 31 and the rear side wall 141 clamp the first magnetic component 20, and the upper frame plate 32 abuts against the top surface of the first magnetic component 20; the fixed frame 30 also includes a lap joint 33 arranged on the side of the front frame plate 31 away from the first magnetic component 20; the limiting pressure plate 40 is detachably fixed to the lower shell 14, and the limiting pressure plate 40 abuts against the lap joint 33.

[0074] In this embodiment, the front frame plate 31 can ensure that the first magnetic part 20 fits the inner wall surface of the rear side wall 141, and the upper frame plate 32 can prevent the first magnetic part 20 from deflecting upward. Since the first magnetic part 20 is a magnet or a ferromagnetic metal, the range of material options is relatively limited. The first magnetic part 20 is indirectly fixed to the lower shell 14 through the fixing frame 30, so there is no need to set a corresponding fixing structure on the first magnetic part 20, thereby reducing the procurement cost or processing cost of the first magnetic part 20. The limiting pressure plate 40 can be specifically used for limiting the fixing frame 30, or it can have other installation functions and be reused for the limiting fixing frame 30. Specifically, the limiting pressure plate 40 can be detachably fixed to the lower shell 14 by screws.

[0075] Further, please refer again to Figures 10 to 15 , and also refer to Fig.16 In one embodiment, the inner wall surface of the rear side wall 141 is provided with two oppositely arranged side panels 145, and the side panels 145 extend in the up-down direction; the fixed frame 30 also includes two side frame panels 34, and the two side frame panels 34 are respectively connected to the left and right sides of the front frame panel 31, and the upper ends of the two side frame panels 34 are connected to the upper frame panel 32; the two side frame panels 34 are located between the two side panels 145, and a gap is formed between the side frame panels 34 and the adjacent side panels 145 for guiding the assembly of the fixed frame 30.

[0076] In this embodiment, the side frame plate 34 of the fixed frame 30 can be quickly assembled to a predetermined position under the guidance of the side panel 145, and can also prevent the fixed frame 30 from deviating excessively from the position in the left and right directions, thereby ensuring that the first magnetic component 20 accurately generates or receives magnetic attraction in the preset area of ​​the first splicing surface 121.

[0077] Furthermore, a lower enclosure panel 146 is provided on the inner wall surface of the bottom wall 142 in an area adjacent to the rear side wall 141. The lower enclosure panel 146 has a main section 146a extending in the left-right direction and spaced apart from the rear edge of the bottom wall 142, and side connecting sections 146b respectively connecting the two ends of the main section 146a and the two side enclosure panels 145; the fixed frame 30 also includes a lower frame plate 35, which is connected to the lower edge of the front frame plate 31 and the two side frame panels 34, and extends to abut against the main section 146a.

[0078] In the present embodiment, when the lower end of the fixed frame 30 tends to shift forward, this tendency can be hindered by setting a lower enclosure plate 146 to abut against the lower frame plate 35 of the fixed frame 30, thereby ensuring the accuracy of the assembly position of the fixed frame 30 and the first magnetic component 20, and further ensuring that the magnetic attraction force that meets the design requirements is generated between the first magnetic component 20 and the second magnetic component 60.

[0079] Furthermore, the lower frame plate 35 also extends to the front side of the front frame plate 31 and is connected to the two side frame plates 34. The inner side surfaces of the upper frame plate 32, the two side frame plates 34 and the lower frame plate 35 are all provided with first limiting convex strips 36. The first magnetic member 20 is a block with multiple side surfaces, and the side surfaces of the first magnetic member 20 are respectively limitedly matched with the first limiting convex strips 36.

[0080] The lower frame plate 35 has a front side surface, a left side surface and a right side surface. The inner side surface of the lower enclosure plate 146 is provided with a plurality of second limiting ridges 146c, which respectively cooperate with the front side surface, the left side surface and the right side surface of the lower frame plate 35.

[0081] In this embodiment, by providing the first limiting ridge 36, the contact area between the fixed frame 30 and the first magnetic part 20 can be reduced, thereby improving the assembly accuracy between the fixed frame 30 and the first magnetic part 20 and reducing the processing cost of processing the corresponding limiting surface. Similarly, providing the second limiting ridge 146c can improve the assembly accuracy between the fixed frame 30 and the lower shell 14 and the processing cost of processing the limiting surface of the lower shell 14 correspondingly used to limit the fixed frame 30. The improvement of the assembly accuracy at two locations can bring about the improvement of the assembly accuracy between the first magnetic part 20 and the lower shell 14, that is, further ensuring the position accuracy between the first magnetic part 20 and the first splicing surface 121.

[0082] Furthermore, the overlapping portion 33 is in the shape of a thin wall extending up and down, and two overlapping portions 33 are provided and are arranged opposite to each other in the left and right directions. Each overlapping portion 33 is connected to the lower frame plate 35 and the front frame plate 31, and the top surface of the overlapping portion 33 is in contact with the lower surface of the limiting pressure plate 40; the limiting pressure plate 40 is a control circuit board arranged horizontally.

[0083] In this embodiment, the overlapping portion 33 is configured to be thin-walled so as to achieve a lightweight design of the component while transmitting pressure; two overlapping portions 33 are provided and arranged at intervals to balance the pressure of the limit pressure plate 40, and also to improve the stability of the fixing frame 30. By using the control circuit board to reuse the limit pressure plate 40 that presses the fixing hole, the reusability of the components is improved, and the number of required components is reduced, making the structure of the electronic mouse more compact.

[0084] Further, please refer again to Figure 5 , and also refer to Figures 17 to 20 In one embodiment, the palm rest 50 includes a base 53 and an upper cover 54 , and the upper cover 54 and the base 53 are engaged and fixed to the second magnetic member 60 .

[0085] In this embodiment, similar to the installation of the first magnetic member 20 , the installation of the second magnetic member 60 can be facilitated by providing the palm rest 50 with a base 53 and an upper cover 54 that are connected up and down, which also helps to reduce the weight of the palm rest 50 .

[0086] Furthermore, the upper cover 54 includes a top wall 541 and a front side wall 542 connected to the front end of the top wall 541 . The front side wall 542 is tilted downward from back to front. The second splicing surface 51 is the outer wall surface of the front side wall 542 , and the second magnetic component 60 is snap-fitted and fixed to the inner wall surface of the front side wall 542 .

[0087] In this embodiment, the second magnetic member 60 is clamped on the inner side of the front side wall 542, similar to the first magnetic member 20 being clamped on the inner wall of the rear side wall 141, so that the distance between the second magnetic member 60 and the second joint surface 51 can be reduced, and the magnetic attraction distance can be reduced to ensure sufficient magnetic attraction. In addition, since the second magnetic member 60 is located on the inner side of the front side wall 542, the palm rest 50 can also provide protection for the second magnetic member 60.

[0088] Furthermore, a support rib 531 extending upward is disposed on the bottom wall of the base 53 , and a front side surface of the support rib 531 abuts against a side of the second magnetic member 60 facing away from the front side wall 542 .

[0089] In this embodiment, by engaging the rear side surface of the second magnetic member 60 with the support rib 531 , the transmission of the clamping force is ensured, and it is also beneficial for the base 53 to achieve a uniform wall thickness and a lightweight design.

[0090] Furthermore, an upper clamping plate 543 is provided on the inner wall surface of the upper cover 54 at the connection between the front side wall 542 and the top wall 541, and a lower clamping plate 532 is provided on the inner wall surface of the base 53 in the area adjacent to the lower end of the front side wall 542; the upper side surface of the second magnetic component 60 abuts against the upper clamping plate 543, and the lower side surface of the second magnetic component 60 abuts against the lower clamping plate 532.

[0091] In this embodiment, an upper clamping plate 543 and a lower clamping plate 532 are provided to respectively clamp the upper side and the lower side of the second magnetic component 60, so that the second magnetic component 60 can be prevented from shaking up and down along the rear side of the front side wall 542, thereby ensuring that the second magnetic component 60 generates or receives magnetic attraction in the set area of ​​the second splicing surface 51.

[0092] Furthermore, in order to prevent the second magnetic component 60 from shifting in the left and right directions, the inner wall surface of the front side wall 542 is provided with two opposite side ribs 544 extending backward, the second magnetic component 60 is arranged between the two side ribs 544, and the left and right side surfaces of the second magnetic component 60 are respectively abutted against the two side ribs 544.

[0093] Furthermore, a third limiting ridge 545 is respectively provided on one of the facing sides of the two side ribs 544 . The third limiting ridge 545 extends in the up-down direction. The left and right side surfaces of the second magnetic member 60 are respectively in limiting contact with the two third limiting ridges 545 .

[0094] In this embodiment, similar to the first and second ridges in the previous embodiments, the contact area between the upper cover 54 and the second magnetic part 60 can be reduced by setting the third limiting ridge 545, thereby improving the assembly accuracy between the upper cover 54 and the second magnetic part 60 and reducing the processing cost of processing the corresponding limiting surface.

[0095] Further, please refer again to Figures 6 to 9 ,as well as Fig.17 and Fig.19 In one embodiment, the anti-detachment clamping structure 12 includes a first clamping surface 121 and a second clamping surface 122 that are relatively arranged. The first clamping surface 121 and the second clamping surface 122 are both arranged to be tilted backward from top to bottom, and a clamping groove is formed on the side facing the first clamping surface 121 and the second clamping surface 122; the anti-detachment matching structure 52 is a cantilever adapted to the clamping groove of the anti-detachment clamping structure 12, and the anti-detachment matching structure 52 includes a first matching surface 521 and a second matching surface 522 formed on the cantilever, the first matching surface 521 is engaged with the second clamping surface 122, and the second matching surface 522 is engaged with the first clamping surface 121.

[0096] In this embodiment, the anti-slipping matching structure 52 cooperates with the snap-fitting groove of the anti-slipping snap-fitting structure 12 by forming a simple cantilever, and the snap-fitting surfaces and the matching surfaces on both sides are snap-fitted with each other, so that the strength of the snap-fitting is ensured with a simple structure. Since the palm rest body 50 is connected to the rear end of the housing 10 and shares a part of the supporting surface of the housing 10 for supporting the user's palm during use, the volume of the palm rest body 50 is smaller than the volume of the housing 10. Therefore, it is more convenient to set the anti-slipping snap-fitting structure 12 as a snap-fitting groove than to set the anti-slipping matching structure 52 as a snap-fitting groove.

[0097] Furthermore, the shell 10 includes an upper shell 13 and a lower shell 14, and the upper shell 13 and the lower shell 14 are covered and enclosed in the up and down directions to form a cavity 15, the edge of the rear part of the upper shell 13 is exposed in the cavity 15, and the first clamping surface 121 is formed on the exposed part of the rear part of the upper shell 13; the shell 10 also includes a side cover 16, the side cover 16 is installed on the side of the lower shell 14, and the side of the side cover 16 adjacent to the lower shell 14 forms a second clamping surface 122.

[0098] In this embodiment, the side cover 16 is combined with the upper shell 13 to form an anti-drop-off clamping structure 12 having a clamping groove feature. Compared with forming the anti-drop-off clamping structure 12 on a single component, the complexity of the single component can be reduced, thereby reducing the manufacturing difficulty. In addition, the side cover 16 can be replaced to combine with the upper shell 13 and the lower shell 14 to form a housing 10 of different styles.

[0099] Further, please refer again to Figures 17 to 20In one embodiment, the palm rest 50 is provided with limit plates 546 extending forward at the left and right edges of the first joint surface 121, and two side covers 16 are provided and respectively installed on the left and right sides of the lower shell 14; the lower shell 14 has a side limit surface 147 exposed from the side cover 16 and connected to the first joint surface 121; the two limit plates 546 cover the outer side of the side limit surface 147, and cooperate with the side limit surface 147 of the lower shell 14 in the left and right directions.

[0100] In this embodiment, the side limiting surface 147 and the first joint surface 121 can be enclosed together to form a boss, and the two limiting plates 546 of the palm rest 50 can form a structure that clamps the boss, thereby increasing the reliability of the palm rest 50 and the shell 10 in the left and right directions.

[0101] Furthermore, in the tilting direction, the distance between the two limit plates 546 gradually increases; the palm rest 50 includes a base 53 and an upper cover 54, the upper cover 54 and the base 53 are snap-fitted and fixed, the second splicing surface 51 and the two limit plates 546 are formed on the upper cover 54, and a plurality of limit protrusions 533 are provided on the bottom wall surface of the base 53, and the plurality of limit protrusions 533 are all located on the side opposite to the two limit plates 546, and the plurality of limit protrusions 533 are respectively abutted against the side opposite to the two limit plates 546.

[0102] In this embodiment, the distance between the two limit plates 546 is gradually reduced, so that the palm rest 50 is more easily snapped into the correct position of the housing 10, because this structure has the function of correcting deviation. Since the limit plates 546 alone may deform and cause the fit to be loose, the limit snap protrusion 533 is provided.

[0103] Furthermore, in order to increase the clamping strength between the shell 10 and the palm rest 50, an anti-detachment clamping structure 12 is respectively provided on the left and right sides of the shell 10; the palm rest 50 includes a base 53 and an upper cover 54, the upper cover 54 is clamped and fixed with the base 53, and an anti-detachment matching structure 52 is respectively provided on the left and right sides of the upper cover 54, and the two anti-detachment matching structures 52 correspond to the two anti-detachment clamping structures 12 one by one.

[0104] Furthermore, the upper cover 54 includes a top wall 541, and the anti-detachment mating structure 52 is a hollow structure with an opening facing downward and / or forward; the anti-detachment mating structure 52 includes a supporting wall 523, a connecting wall 524 and a palm rest wall 525, the supporting wall 523 is formed by extending upward from the edge of the top wall 541, the connecting wall 524 is formed by extending laterally from the rear edge of the supporting wall 523, the palm rest wall 525 is connected to the edge of the connecting wall 524 away from the supporting wall 523, and the shape of the outer side surface of the palm rest wall 525 is suitable for supporting a part of the palm during use; the first mating surface 521 forms the outer side surface of the connecting wall 524, and the second mating surface 522 is formed on the front and lower side surface of the palm rest wall 525.

[0105] In this embodiment, the two anti-slipping matching structures 52 are designed as hollow structures, which is conducive to realizing the lightweight design of the upper cover 54. When the electronic mouse is used, the palm rest wall 525 of one anti-slipping matching structure 52 can be used to support the hypothenar part of the palm, and the palm rest wall 525 of the other anti-slipping matching structure 52 can be used to support the thenar part of the palm, so that a larger support surface can be formed, thereby improving the comfort of long-term use of the mouse.

[0106] For further information, please refer to Fig.21 and Fig. 22 In one embodiment, unlike the mouse palm rest 200A of the previous embodiment, the palm rest body 50 of the mouse palm rest 200B of the second embodiment further includes a thumb rest 55 connected to the front end of one of the palm rest walls 525; the shape of the upper surface of the thumb rest 55 is suitable for supporting a part of the thumb during use.

[0107] In this embodiment, for a right-handed person, the thumb rest 55 can be connected to the front end of the palm rest wall 525 on the left side; for a left-handed person, the thumb rest 55 is connected to the front end of the palm rest wall 525 on the right side. By providing the thumb rest 55, the thumb can also be supported during the use of the electronic mouse. It is understandable that the thumb rest 55 can be a solid structure or a hollow structure. The hollow structure can be integrally formed with the upper cover 54.

[0108] For further information, please refer to Fig.23 and Fig.24 In one embodiment, unlike the wired electronic mouse (including the mouse body 100A) in the previous embodiment, the electronic mouse of this embodiment is a wireless electronic mouse. The electronic mouse (including the mouse body 100B) also includes a wireless transmitter (not shown) and a wireless receiver 300. The mouse palm rest 200B is located between the lower surface of the rear part of the shell 10 and the extended surface of the bottom surface of the shell 10. The lower surface of the rear part of the shell 10 of the mouse palm rest 200B is provided with a storage groove 148. The wireless receiver 300 can be detachably stored in the storage groove 148. The palm rest body 50 shields the lower end of the wireless receiver 300. The wireless receiver 300 is used to receive the signal of the wireless transmitter when connected to the host computer.

[0109] In this embodiment, the communication between the wireless receiver 300 and the wireless transmitter can be Bluetooth communication. The wireless receiver 300 is a hidden design, and there is no need to open a slot on the appearance of the electronic mouse to accommodate the wireless receiver 300, which makes the overall appearance of the electronic mouse more simple. Fig.23By connecting a data cable such as a type C data cable, the battery in the mouse body 100B can be charged. It is understandable that the data communication function of the data cable can also be used to update the firmware in the mouse body 100B. The mouse palm rest 200A of the first embodiment and the mouse palm rest 200B of the second embodiment can be used with the mouse body 100A or the mouse body 100B.

[0110] Furthermore, when the wireless receiver 300 is detachably stored in the storage slot 148, the lower end of the wireless receiver 300 protrudes from the lower surface of the rear portion of the shell 10; the upper surface of the palm rest 50 is provided with a avoidance groove 548 for avoiding the lower end of the wireless receiver 300 when assembled in an inclined direction, and the bottom surface of the avoidance groove 548 is lower than the upper edge of the second splicing surface 51.

[0111] In this embodiment, the protrusion at the lower end of the wireless receiver 300 can be easily grasped, so that the wireless receiver 300 can be more conveniently taken out from the storage slot 148. By setting the avoidance slot 548 to avoid the lower end of the wireless receiver 300, the wireless receiver 300 will not hinder the clamping of the palm rest 50. Structurally, the size of the avoidance slot 548 is adapted to the activity space of the lower end of the wireless receiver 300, so in the front-to-back direction, the width of the avoidance slot 548 is greater than the width of the wireless receiver 300. The bottom surface of the avoidance slot 548 is lower than the upper edge of the second splicing surface 51. In this way, in a relatively limited space, on the one hand, the avoidance slot 548 is prevented from occupying the space of the second splicing surface 51, and at the same time, the area of ​​the second splicing surface 51 can be relatively increased, thereby ensuring sufficient magnetic attraction.

[0112] Furthermore, an elastic arm 148 a is provided on the inner wall surface of the storage groove 148 , and the elastic arm 148 a is used to press the wireless receiver 300 laterally against the circumference of the wireless receiver 300 when the wireless receiver 300 is detachably stored in the storage groove 148 .

[0113] In this embodiment, after the wireless receiver 300 is inserted into the receiving slot 148 , the elastic force of the elastic arm 148 a can apply a biasing force to the wireless receiver 300 , so that the wireless receiver 300 will not be easily released from the receiving slot 148 .

[0114] Those skilled in the art will appreciate that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0115] 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 all be included in the scope of the claims of the present invention.
