the mouse body (100A, 100B) comprises a shell 10 and a first magnetic part 20, the shell 10 is provided with a first splicing surface 121 arranged towards the back, and the first magnetic part 20 is arranged corresponding to the first splicing surface 121; the left side and the right side of the shell 10 are respectively provided with an anti-falling clamping structure 12;

the mouse palm rest (200A, 200B) comprises a palm rest body 50 and a second magnetic piece 60, the palm rest body 50 is provided with a second splicing surface 51 arranged forwards, and the second magnetic piece 60 is arranged corresponding to the second splicing surface 51; the attraction between the first magnetic element 20 and the second magnetic element 60 keeps the first splicing surface 121 attached to the second splicing surface 51;

the bottom surface of the palm rest 50 is flush with the bottom surface of the shell 10, and the left and right sides of the palm rest 50 are further provided with anti-disengaging matching structures 52, and the anti-disengaging matching structures 52 protrude along an inclined direction so as to be in clamping fit with the corresponding anti-disengaging clamping structures 12, and the inclined direction has a forward component and an upward component.

In this embodiment, the housing 10 provides an accommodating space and a supporting body for a plurality of components. The housing 10 is typically assembled from a plurality of components. The shape of the housing 10 is also complex due to the number of functions to be fulfilled, so that the main structure thereof is preferably injection molded. The first magnetic member 20 and the second magnetic member 60 may be a combination of a magnet and a ferromagnetic metal, or a combination of a magnet and a magnet. It will be appreciated that functionally equivalent results can be achieved if electromagnetic means are employed. The first splicing surface 121 and the second splicing surface 51 are attached to each other so as to be complementary in shape, and 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 in shape-association with the first splicing surface 121, the first splicing surface 121 is generally designed to be flat. The anti-disengaging clamping structure 12 and the anti-disengaging matching structure 52 are clamped, the connection model is the matching between the protrusion and the groove, the anti-disengaging clamping structure 12 can be either the protrusion or the groove, and the anti-disengaging matching structure 52 can be the groove and the protrusion correspondingly.

According to the electronic mouse with the detachable palm rest, the first magnetic piece 20 and the second magnetic piece 60 are respectively arranged in the mouse bodies (100A, 100B) and the mouse palm rests (200A, 200B), so that when the electronic mouse is lifted off a supporting surface such as a desktop, the first splicing surface 121 of the shell 10 can be kept attached to the second splicing surface 51 of the palm rest body 50 through magnetic attraction, connection of the first splicing surface and the second splicing surface is kept, and a user can conveniently detach the mouse palm rests (200A, 200B) from the mouse bodies (100A, 100B) along the direction opposite to the inclination direction. In addition, since the anti-disengagement structure 52 of the palm rest body 50 is engaged with the anti-disengagement structure 12 of the housing 10 along an inclined direction having a forward and upward component, and is bilaterally engaged in a direction perpendicular to the inclined direction and parallel to the vertical longitudinal surface, the corresponding engagement structure can form a self-locking structure with a supporting surface such as a desktop to prevent the mouse palm rests (200A, 200B) from being disengaged from the mouse bodies (100A, 100B) regardless of whether the mouse is operated forward or dragged backward, thereby ensuring that the mouse palm rests (200A, 200B) are reliably connected with the mouse bodies (100A, 100B) during use. In conclusion, the electronic mouse with the detachable palm rest is easy to detach when lifted off a desktop, and the reliable connection of the mouse palm rests (200A and 200B) can be ensured when dragged, so that the electronic mouse has the characteristics of convenience in use and wrist fatigue relief.

Further, referring to fig. 10 to 11, in an embodiment, the housing 10 includes an upper shell 13 and a lower shell 14, the upper shell 13 and the lower shell 14 cover and enclose the cavity 15 along an up-down direction, and the first magnetic member 20 is disposed in the cavity 15 and fixedly mounted on an inner wall surface of the lower shell 14.

In this embodiment, the housing 10 is configured to be opened and closed up and down, so that the first magnetic member 20 is advantageously installed in the cavity 15 of the housing 10, and thus the housing 10 can provide a protective effect for the first magnetic member 20.

The first magnetic member 20 is mounted on the inner side surface of the rear sidewall 141, so that the distance between the first magnetic member 20 and the first splicing surface 121 can be reduced as much as possible, the loss of the magnetic attraction distance is reduced, and the sufficient magnetic attraction force is ensured.

Further, referring to fig. 5 and fig. 10 to 15 again, in an embodiment, the mouse body (100A, 100B) further includes a fixing frame 30 and a limiting pressing plate 40, the fixing frame 30 includes a front frame plate 31 and an upper frame plate 32, the front frame plate 31 and the rear sidewall 141 sandwich the first magnetic element 20, and the upper frame plate 32 abuts against a top surface of the first magnetic element 20; the fixing frame 30 further comprises a lapping part 33 arranged on one surface of the front frame plate 31, which is far away from the first magnetic part 20; the limiting pressure plate 40 is detachably fixed with the lower shell 14, and the limiting pressure plate 40 abuts against the overlapping part 33.

Since the first magnetic member 20 is a magnet or a ferromagnetic metal, the material selection range is relatively limited. The first magnetic member 20 is indirectly fixed to the lower case 14 through the fixing frame 30, so that there is no need to provide a corresponding fixing structure on the first magnetic member 20, and thus the procurement cost or the processing cost of the first magnetic member 20 can be reduced. The limiting pressure plate 40 may be used exclusively for the limiting fixing frame 30 or may have a structure of other mounting functions and reused for the limiting fixing frame 30. Specifically, the limiting pressure plate 40 can be detachably fixed with the lower shell 14 by using screws.

Further, referring to fig. 10 to 15 again and also fig. 16, in an embodiment, the inner wall surface of the rear sidewall 141 is provided with two opposite side panels 145, and the side panels 145 extend in the vertical direction; the fixed frame 30 further comprises two side frame plates 34, the two side frame plates 34 are respectively connected to the left and right side edges of the front frame plate 31, and the upper ends of the two side frame plates 34 are connected with the upper frame plate 32; the side frame plates 34 are positioned between the side coamings 145, and a gap for guiding the assembly of the fixing frame 30 is formed between the side frame plates 34 and the adjacent side coamings 145.

Similarly, the provision of the second restriction convex strip 146c can improve the assembly accuracy between the fixing frame 30 and the lower case 14 and the processing cost for processing the restriction surface of the lower case 14 for restricting the fixing frame 30 accordingly. The improvement of the assembling precision at two positions can bring about the improvement of the assembling precision between the first magnetic element 20 and the lower shell 14, that is, the position precision between the first magnetic element 20 and the first splicing surface 121 is further ensured.
