[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] See also Figures 1 to 7 The body structure 100 of the handheld device provided by the utility model includes a shell 110, an input component 120 and a motor bracket 130; the shell 110 is cylindrical and defines a mounting cavity 111, one end of the shell 110 is provided with a through hole 112 connected to the mounting cavity 111, and the outer peripheral wall of the shell 110 adjacent to the through hole 112 forms a pressing area 113 and an error touch area 114 located on the periphery of the pressing area 113; the input component 120 includes a main body installed in the mounting cavity 111 The main control board 121 and the flexible pad 122, the input button 1211 is arranged at the position opposite to the pressing area 113 of the main control board 121, and the flexible pad 122 is installed between the pressing area 113 and the input button 1211; the motor bracket 130 is arranged in the installation cavity 111 and abuts against the side 121 of the main control board facing away from the flexible pad 122, and the motor bracket 130 is provided with a supporting boss 131 at the position opposite to the false touch area 114, and the supporting boss 131 is used to support the false touch area 114.

[0043] The housing 110 is cylindrical, and the shape of its cross section can be selected in many ways, for example, the cross section of the housing 110 can be circular, elliptical, square, regular polygonal, etc., which is not specifically limited here. The mounting cavity 111 inside the housing 110 is used for the installation of the input assembly 120, the motor bracket 130, the motor and other structural parts. Therefore, one end of the housing 110 is usually open to allow the input assembly 120, the motor bracket 130, the motor and other structural parts to be installed in the mounting cavity 111. The other end of the housing 110 is also penetrated by a through hole 112 connected to the mounting cavity 111, so that the drive shaft connected to the motor can extend.

[0044] The pressing area 113 on the outer wall of the shell 110 can produce slight deformation when subjected to external force, that is, the thickness of the pressing area 113 on the shell 110 is thinner than the thickness of other positions of the shell 110, which can ensure that the pressing area 113 can be quickly deformed after being pressed; the false touch area 114 on the outer wall of the shell 110 located outside the pressing area 113 can also be deformed when pressed by external force, that is, when the false touch area 114 is pressed, it will lead the pressing area 113 to deform together, which can easily create the illusion that the pressing area 113 is pressed, and then lead to the problem of erroneous operation.

[0045] The input assembly 120 includes a main control board 121 and a flexible pad 122. The main control board 121 is usually arranged in a long strip shape. It is installed in the installation cavity 111 and arranged along the extension direction of the installation cavity 111. The main control board 121 is provided with an input button 1211 at a position opposite to the pressing area 113. The input button 1211 can be a mechanical button, a micro switch, a pressure sensor, etc. The flexible pad 122 can be rubber or silicone. The flexible pad 122 is arranged between the pressing area 113 and the input button 1211. When the flexible pad 122 is assembled between the pressing area 113 and the input button 1211, it is squeezed, that is, the flexible pad 122 is elastically abutted against the pressing area 113 and the input button 1211. In this way, the gap between the pressing area 113 and the input button 1211 can be eliminated by using the flexible pad 122 to improve the sensitivity of the input button 1211.

[0046] The motor bracket 130 can be set in a cylindrical shape, or in a ring shape with an unsealed side. In this case, the cross section of the motor bracket 130 is an unsealed ring shape. The motor bracket 130 can also be set in other shapes, which are not specifically limited here. The motor bracket 130 is fixedly installed in the installation cavity 111, and the motor bracket 130 also abuts against the main control board 121, that is, the main control board 121 can be fixed on the outer peripheral wall of the motor bracket 130. The support boss 131 provided at the position of the motor bracket 130 relative to the false touch area 114 can be set in a block shape or in a long strip shape, which is not limited here. The support boss 131 is used to abut against the false touch area 114 to limit the deformation of the false touch area 114 when pressed by external force.

[0047] The utility model sets a pressing area 113 at a position where the shell 110 is opposite to the input button 1211. After being pressed, the pressing area 113 is deformed and abuts against the flexible pad 122 and triggers the input button 1211 to realize the input of the control command; a supporting boss 131 is set at a position where the motor bracket 130 is opposite to the false touch area 114 of the shell 110. The supporting boss 131 is used to abut against the false touch area 114 of the shell 110, so that the deformation of the false touch area 114 can be limited to a relatively small amount or even zero, thereby avoiding the problem that when the false touch area 114 is pressed, the pressing area 113 is deformed, which in turn causes the input button 1211 to be triggered by mistake.

[0048] In some embodiments of the present invention, the number of the supporting bosses 131 is at least two, that is, the supporting bosses 131 may be two, three, four or even more, and at least two supporting bosses 131 are disposed on two opposite sides of the main control board 121 in the circumferential direction of the motor bracket 130. For details, please refer to Figure 5 and Figure 7In one embodiment of the utility model, the number of the supporting bosses 131 is two, and the two supporting bosses 131 are located at two opposite sides of the main control board 121 in the circumferential direction of the motor bracket 130, and the two supporting bosses 131 are respectively in contact with the positions opposite to the false touch area 114, so that the two positions opposite to the false touch area 114 can be supported, which is conducive to ensuring the overall force balance of the sensitive trigger area, so that it can further ensure that the input key 1211 will not be triggered by mistake when the false touch area 114 is pressed. In addition, the two supporting bosses 131 can also limit the main control board 121 in the circumferential direction of the motor bracket 130, so as to avoid the displacement of the main control board 121 along the circumferential direction of the motor bracket 130.

[0049] See also Figure 5 In some embodiments of the utility model, the support boss 131 is arranged to extend along the axial direction of the motor bracket 130, the axial direction of the motor bracket 130 is the same as the axial direction of the housing 110, two first ribs 132 are arranged on one side of the support boss 131 adjacent to the main control board 121, and two second ribs 133 are arranged on the other side of the support boss 131 facing away from the main control board 121, and the two first ribs 132 and the two second ribs 133 are arranged at intervals in the axial direction of the motor bracket 130. In this way, the supporting points of the support boss 131 in the circumferential direction of the motor bracket 130 are increased, so as to ensure the connection strength between the support boss 131 and the motor bracket 130, thereby ensuring that the support boss 131 is not easy to break.

[0050] Furthermore, the two first ribs 132 are connected by a third rib 134, which is also fixedly connected to the motor bracket 130; and / or the two second ribs 133 can also be connected by a fourth rib (not shown), which is also fixedly connected to the bracket. Such an arrangement can further enhance the strength of the connection between the two first ribs 132 and the two second ribs 133 and the motor bracket 130, and the arrangement of the two first ribs 132, the two second ribs 133, the third rib 134 and the fourth rib increases the connection area between the support boss 131 and the motor bracket 130 in disguised form, so that the connection between the support boss 131 and the motor bracket 130 is more firmly established.

[0051] Based on the above embodiments, it should be noted that the motor bracket 130 is installed on the power supply machine, one end of the driving shaft of the handheld device is connected to the motor transmission, and the other end of the driving shaft of the handheld device passes through the through hole 112 of the shell 110 and is connected to the toothbrush head of the handheld device. When the handheld device is working, the head will drive the driving shaft to deviate to one side due to the action of external force, which will cause one side of the motor bracket 130 to move in the direction close to the shell 110, especially when the motor bracket 130 swings in the direction close to the pressing area 113, it is also easy to cause the input button 1211 to be triggered by mistake.

[0052] Based on the above questions, please refer to Figures 8 to 10 In some embodiments of the utility model, the cavity wall of the installation cavity 111 is provided with two assembly grooves 115, and the two assembly grooves 115 are both extended along the axial direction of the housing 110. The two assembly grooves 115 are also arranged on both sides of the false touch area 114 in the circumferential direction of the housing 110. The outer peripheral wall of the motor bracket 130 is provided with two assembly ridges 135, and each assembly ridge 135 is tightly matched with the corresponding assembly groove 115. In this way, the cooperation between the two assembly ridges 135 and the two assembly grooves 115 can be used to limit the swing of the motor bracket 130 relative to the housing 110. In addition, combined with the technical solution of the support boss 131 against the false touch area 114, the motor bracket 130 can be limited to swing in the direction close to the pressing area 113, thereby avoiding the problem of the input button 1211 being mistakenly triggered due to the swing of the motor bracket 130.

[0053] In some embodiments of the present invention, the orthographic projection of each assembly ridge 135 in the direction of the input component 120 close to the housing 110 at least partially overlaps with the pressing area 113, that is, the orthographic projection of each assembly ridge 135 in the direction of the input component 120 close to the housing 110 can overlap with the pressing area on at least one side adjacent to the motor bracket 130, thereby ensuring that each assembly ridge 135 plays a supporting role when the pressing area 113 is pressed, thereby avoiding the position of the motor bracket 130 from being offset when the pressing area 113 is pressed.

[0054] It should be noted that there are many positions where the two assembly grooves 115 are set. The central angle corresponding to the two assembly grooves 115 can be 180 degrees, the central angle corresponding to the two assembly grooves 115 can also be 160 degrees, or the central angle corresponding to the two assembly grooves 115 can also be other angles, which are not limited here. Preferably, the central angle corresponding to the two assembly grooves 115 is 180 degrees, that is, the notches of the two assembly grooves 115 are arranged relative to each other, and the central angles corresponding to the two assembly grooves 115 and the pressing area 113 are equal, that is, the central angle corresponding to each assembly groove 115 and the pressing area 113 is 90 degrees. This arrangement makes the two opposite sides of the motor bracket 130 bear balanced forces, and at the same time, the assembly direction of the two assembly ridges 135 is perpendicular to the swing direction of the motor bracket 130, so that the motor bracket 130 can be better constrained.

[0055] Further, each assembly convex strip 135 includes at least two assembly sections 1351 and at least one connecting section 1352, two adjacent assembly sections 1351 are connected by a connecting section 1352, the assembly sections 1351 of each assembly convex strip 135 are tightly matched with the corresponding assembly groove 115, and the connecting section 1352 of each assembly convex strip 135 is loosely matched with the corresponding assembly groove 115. In this way, the area of ​​tight fit between each assembly convex strip 135 and the corresponding assembly groove 115 can be reduced, which is convenient for the assembly convex strip 135 to fit with the corresponding assembly groove 115, and further facilitates the assembly of the motor bracket 130 and the housing 110.

[0056] Furthermore, the assembly segment 1351 adjacent to the through hole 112 of the at least two assembly segments 1351 of each assembly ridge 135 is wedge-shaped, and one end of the assembly ridge 135 adjacent to the through hole 112 can be formed by the assembly segment 1351, and of course can also be formed by the connecting segment 1352, and no specific limitation is made here. The width of the assembly segment 1351 adjacent to the through hole 112 is gradually reduced in the direction approaching the through hole 112, so that the assembly segment 1351 adjacent to the through hole 112 can be more easily inserted into the corresponding assembly groove 115, thereby facilitating the entire assembly ridge 135 to slide relative to the corresponding assembly groove 115 until it is assembled into place.

[0057] See also Figure 5 and Fig.11 In some embodiments of the present invention, the outer peripheral wall of the motor bracket 130 facing the pressing area 113 is further provided with a supporting structure 136, and the supporting structure 136 and the supporting boss 131 are arranged at intervals in the axial direction of the motor bracket 130, and the supporting structure 136 is used to abut against the position of the housing 110 located between the through hole 112 and the false touch area 114. In this way, the side of the motor bracket 130 facing the pressing area 113 is limited by the supporting boss 131 and the supporting structure 136, and the supporting structure 136 is arranged near the through hole 112, so that the motor bracket 130 is less likely to swing in the direction close to the pressing area 113, thereby ensuring that the input button 1211 will not be mistakenly triggered due to the swing of the motor bracket 130.

[0058] Specifically, the support structure 136 includes a first support block 1361, which is arranged on the outer peripheral wall of the motor bracket 130 facing the pressing area 113, and the first support block 1361 extends along the circumference of the motor bracket 130. The first support block 1361 is used to abut with the position of the shell 110 located between the through hole 112 and the false touch area 114. The first support block 1361 is also used to abut and cooperate with one end of the main control board 121 adjacent to the through hole 112. In this way, the first support block 1361 and the support boss 131 form a support line, especially when the first support block 1361 and the two support bosses 131 cooperate, they can form a support surface, which can not only limit the motor bracket 130 from swinging in the direction close to the pressing area 113, but also limit the deformation of the false touch area 114, thereby further reducing the problem of preventing false touch of the input key 1211. In addition, the first support block 1361 can also limit the main control board 121 in the axial direction of the motor bracket 130.

[0059] Please continue reading Fig.11 The support structure 136 also includes two second support blocks 1362, which are arranged on the outer peripheral wall of the motor bracket 130 facing the pressing area 113. The two second support blocks 1362 are also located on both sides of the main control board 121 in the circumferential direction of the motor bracket 130. The two second support blocks 1362 are respectively used to abut against the position of the housing 110 between the through hole 112 and the false touch area 114. The two second support blocks 1362 also limit the main control board 121 in the circumferential direction of the motor bracket 130. In this way, the end of the motor bracket 130 adjacent to the through hole 112 can be limited by a first support block 1361 and two second support blocks 1362. The setting of multiple support points ensures that the end of the motor bracket 130 adjacent to the through hole 112 is more firmly limited.

[0060] For further information, see Fig.12 The outer peripheral wall of the motor bracket 130 opposite to the pressing area 113 is provided with a mounting plane 137, which is arranged to extend along the axial direction of the motor bracket 130. The mounting plane 137 is used to abut against the main control board 121. In this way, the contact area between the motor bracket 130 and the main control board 121 is increased, so that the motor bracket 130 can support the main control board 121 more stably. At the same time, the ends of the two second support blocks 1362 away from the motor bracket 130 are also provided with limiting hooks 1363. The limiting hooks 1363 limit the main control board 121 from separating from the mounting plane 137 in the radial direction of the motor bracket 130. In this way, the main control board 121 can be directly fixed on the motor bracket 130, so as to facilitate the assembly of the motor bracket 130 and the main control board 121.

[0061] The present invention also provides a handheld device, which may be an electric toothbrush, an electric shaver, etc. The handheld device includes a head and a body structure 100 of the handheld device, and the head is used in conjunction with the body structure 100 of the handheld device. The specific structure of the body structure 100 of the handheld device refers to the above embodiment. Since the handheld device adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.
