Description

Technical Field

[0002] In some industries that need to manage goods, such as the retail industry or the logistics industry, operators need to use a scanning device to scan the barcode of the goods in order to sort, pick up or count the goods. Nowadays, some manufacturers have developed wearable devices that can be worn on the palm of the hand to facilitate goods management operations, such as the ZEBRARS2100 Bluetooth wearable scanner. The wearable device has a container and a trigger switch. The operator wears the cloth wearable device on the palm of the hand, and the scanner is placed in the container. The operator presses the trigger switch to trigger the scanner to scan.

[0003] The container and trigger switch of the existing wearable device are as follows Figure 1 and Figure 2 As shown, the trigger switch A is connected to the container B via the wire C, and the portable scanner is set in the container B. The operator operates the trigger switch A to start the portable scanner for scanning, and the operator releases the trigger switch A, and the portable scanner stops scanning.

[0004] The existing trigger switch A includes a base A1, a limit support body A2 and a pressing body A3, a circuit board A4 and a switch spring A5 are arranged on the base A1, the limit support body A2 is arranged on the base A1 and surrounds the circuit board A4 and the switch spring A5, and an annular groove A21 is provided on the top surface of the limit support body A2 for accommodating the pressing body A3, and the convex pin of the pressing body A3 passes through the through hole A22 on the top surface of the limit support body A2 and abuts against the switch spring A5.

[0005] On the one hand, the trigger switch A of this structure has a large number of components. On the other hand, if the pressing position is too close to the edge, only a slight force is required and the edge of the pressing body A3 will move downward until it is stopped by the groove wall of the annular groove A21, so that the force cannot be increased. Too small a force cannot overcome the pressure required to move the switch spring A5. In this way, the edge of the trigger switch A often forms a dead point of pressing, which is not conducive to the operation of the trigger scanner. Summary of the invention

Figure 5 yes Figure 3 A perspective view of the one-handed trigger device from another perspective, Figure 6 yes Figure 3 Section view along line AA, Figure 7 yes Figure 3 Cross-sectional view along line BB. As shown in the figure, the one-hand-operated trigger device 1 of the present embodiment includes a switch assembly 10, a base assembly 20, a pressing assembly 30 and a limit pressurizing mechanism 40. The one-hand-operated trigger device 1 also includes a device accommodating assembly 50, and the device accommodating assembly 50 is used to accommodate an electronic device, such as a portable scanner. Herein, the first direction L1 is defined as a vertical direction, and the second direction L2 and the third direction L3 are defined as two directions perpendicular to each other on a horizontal plane, that is, the first direction L1 is perpendicular to the second direction L2 and the third direction L3. The second direction L2 of the present embodiment corresponds to the long side direction of the base assembly 20 and the pressing assembly 30, and the third direction L3 of the present embodiment corresponds to the short side direction of the base assembly 20 and the pressing assembly 30.

[0052] The switch assembly 10 includes a first contact component 11, a second contact component 12, a first wire 13 electrically connected to the first contact component 11, and a second wire 14 electrically connected to the second contact component 12. The first contact component 11 and the second contact component 12 are arranged on a circuit board 15. The first contact component 11 of the present embodiment is an arc-shaped spring-like component and protrudes away from the second contact component 12 along the first direction L1. The second contact component 12 is a contact structure arranged on the circuit board 15. The first contact component 11 is arranged above the second contact component 12 along the first direction L1. The edge of the first contact component 11 is arranged on the circuit board 15, and its arc-shaped spring has a predetermined distance from the second contact component 12. The first wire 13 and the second wire 14 are electrically connected to the circuit board 15, and are electrically connected to the first contact component 11 and the second contact component 12 through the circuit of the circuit board 15. The first contact part 11 moves downward along the first direction L1 and contacts the second contact part 12, so that the first wire 13 and the second wire 14 are in a conducting state. Alternatively, the first contact part 11 moves upward along the first direction L1 and separates from the second contact part 12, so that the first wire 13 and the second wire 14 are in a disconnected state.

[0053] The base assembly 20 includes a support member 21 and a plurality of first extension members 22. The support member 21 supports the circuit board 15, that is, supports the first contact member 11 and the second contact member 12. The plurality of first extension members 22 extend from the edge of the support member 21 along the first direction L1 close to the switch assembly 10, and the plurality of first extension members 22 are arranged in pairs at least in the second direction L2 and the third direction L3 on opposite sides of the support member 21. The plurality of first extension members 22 of this embodiment are connected to each other to form an extended peripheral wall.

[0054] The support member 21 includes a support member body 211, a plurality of support ribs 212, a plurality of positioning posts 213 and a plurality of snap members 214. The support member body 211 is a bottom plate structure, and a plurality of support ribs 212 are arranged on the support member body 211 and extend along the second direction or / and the third direction to support the circuit board 15, that is, to support the first contact component 11 and the second contact component 12. A plurality of positioning posts 213 extend away from the support member body 211 and the support ribs 212 along the first direction L1, and the circuit board 15 has a plurality of positioning holes 151, and the plurality of positioning posts 213 pass through the plurality of positioning holes 151, so that the circuit board 15, the first contact component 11 and the second contact component 12 are limited on the support member 21 in the second direction L2 and the third direction L3. A plurality of snap members 214 are disposed on opposite sides of the plurality of supporting ribs 212 and away from the supporting member body 211 along the first direction L1. The ends of the snap members 214 are barbed structures and abut against the circuit board 15, so that the circuit board 15, the first contact component 11 and the second contact component 12 are limited in the first direction L1 on the supporting member 21. In this way, the supporting ribs 212, the positioning posts 213 and the snap members 214 realize a structure in which the circuit board 15 is limited in the first direction L1, the second direction L2 and the third direction L3.

[0055] The support member 21 also includes two wire grooves 215 formed between the plurality of support ribs 212 and the plurality of snap members 214. A through hole 216 is formed between two adjacent first extension members 22. The through hole 216 of this embodiment is located on one side of the second direction L2. The first wire 13 and the second wire 14 enter the two wire grooves 215 of the support member 21 through the through hole 216. In this way, the circuit board 15 is installed on the support rib 212 to cover and abut against the first wire 13 and the second wire 14 at the same time. The circuit board 15 is limited in the first direction L1, the second direction L2 and the third direction L3 by the support rib 212, the positioning column 213 and the snap member 214, and the first wire 13 and the second wire 14 are limited in the first direction L1 at the same time. Therefore, the support member 21 also plays a role in organizing the first wire 13 and the second wire 14.

[0056] The pressing assembly 30 includes a pressing body 31, a contact member 32, and a plurality of second extension members 33. The pressing body 31 is a plate-like structure. The contact member 32 approaches the switch assembly 10 along the first direction L1 from the surface of the pressing body 31 and contacts the first contact member 11. The contact member 32 of this embodiment is columnar and is disposed at the center of the pressing body 31. The contact member 32 contacts a contact position of the first contact member 11. The plurality of second extension members 33 are disposed on opposite sides of the pressing body 31 in the second direction L2 and the third direction L3 and extend along the first direction L1 close to the base assembly 20.

[0057] The size of the pressing body 31 of this embodiment is smaller than that of the supporting member 21 , so when the pressing assembly 30 is assembled to the base assembly 20 , the second extending member 33 is closer to the switch assembly 10 than the first extending member 22 . That is, the second extending member 33 is located inside the first extending member 22 .

[0058] The position limiting and pressurizing mechanism 40 is provided on the plurality of first extension members 22 and the plurality of second extension members 33. The position limiting and pressurizing mechanism 40 includes a plurality of abutting protrusions 41 and a plurality of abutting slots 42. The plurality of abutting protrusions 41 abut against the hole walls of the plurality of abutting slots 42 in the first direction L1. In this embodiment, the plurality of abutting protrusions 41 are provided on the plurality of second extension members 33, and the plurality of abutting slots 42 are provided on the plurality of first extension members 22. The abutting protrusion 41 is in the shape of a convex hook. Since the second extension member 33 is closer to the switch assembly 10 than the first extension member 22, that is, the second extension member 33 is located on the inner side of the first extension member 22, the abutting protrusion 41 extends from the side of the abutting slot 42 close to the switch assembly 10 to the side away from the switch assembly 10. In this embodiment, the abutting protrusion 41 abuts against the slot wall on the side of the abutting slot 42 away from the support member body 211, and there is a retreat distance D between the end of the second extension member 22 and the support member body 211.

[0059] Please also read Figure 8 , which is Figure 7 Schematic diagram of the pressing body of the pressing assembly applying force on one side. When the user applies force on one side of the pressing body 31, the force-applying side P1 is defined, and the side of the pressing body 31 opposite to the force-applying side is defined as the abutting side P2. At least one abutting protrusion 41 of the abutting side P2 remains in abutment with the hole wall of the abutting slot 42, so that the user can continue to increase the force applied and finally make the abutting member 32 push the first contact component 11 to move along the first direction L1 and contact the second contact component 12.

[0060] Please also read Fig. 9 , which is Figure 3 Cross-sectional view along line CC. The device housing assembly 50 includes a housing 51, an electrical connector 52, and a snap-fitting positioning member 53. The housing 51 has a bottom wall 511 and a peripheral wall 512, the bottom wall 511 is connected to the peripheral wall 512 to form a housing groove 513, a snap-fitting groove 514 is formed on the peripheral wall 512, the housing groove 513 and the snap-fitting groove 514 are opened on opposite sides of the housing 51, and the inner surface of the peripheral wall 512 of the housing 51 is provided with two slots 511a, so that the snap-fitting groove 514 is connected to the housing groove 513.

[0061] The electrical connector 52 connects the first wire 13 and the second wire 14 and is combined with the clamping positioning member 53. The electrical connector 52 includes an electrical connector body 521 and two electrical connection structures 522 disposed on the surface of the electrical connector body 521. The clamping positioning member includes a coupling groove 533, which is formed on the surface of the clamping positioning member 53 close to the receiving groove 513 of the receiving member 51. The electrical connector 52 is positioned in the coupling groove 533, and the two electrical connection structures 522 extend into the receiving groove 513.

[0062] The engaging positioning member 53 is engaged with the engaging groove 514 and positioned in the accommodating member 51. The engaging groove 514 includes two first engaging ends 5141 disposed on opposite sides thereof, and the engaging positioning member 53 includes two second engaging ends 531 disposed on opposite sides thereof and a stress deformation notch 532 located between the two second engaging ends. The two first engaging ends 5141 and the two second engaging ends 531 are step-shaped structures that match each other, and the distance between the two first engaging ends 5141 is smaller than the distance between the two second engaging ends 531. Therefore, when the engaging positioning member 53 is engaged with the engaging groove 514, the second engaging end 531 away from the stress deformation notch 532 is first engaged with a first engaging end 5141 of the engaging groove 514, and then the engaging positioning member 53 is rotated to make the second engaging end 531 close to the stress deformation notch 532 engage with the corresponding first engaging end 5141, and the engaging positioning member 53 generates stress deformation at the elastic deformation notch 532, so that the engaging positioning member 53 is engaged with the engaging groove 514. The second engaging end 531 close to the stress deformation notch 532 of the engaging positioning member 53 forms a guiding inclined surface 5311, and when the second engaging end 531 is pushed into the engaging groove 514, the guiding inclined surface 5311 abuts against the end edge of the first engaging end 5141 and can smoothly push the stress deformation notch 532 to generate stress deformation, and finally the second engaging end 531 is engaged with the corresponding first engaging end 5141.

[0063] like Figure 4 and Figure 5 As shown, the device accommodating assembly 50 further includes a wire positioning member 54, and the accommodating member 51 further includes a wire positioning groove 515 formed on the bottom wall 511 of the accommodating member 51. The first wire 13 and the second wire 14 are combined with the wire positioning member 54, for example, by injection molding to form an integrated structure. The portion of the electrical connector 52 connected to the first wire 13 and the second wire 14 abuts against the wire positioning member 54, and the wire positioning member 54 is combined with the wire positioning groove 515 through a configuration matching structure.

[0064] See also Figures 10 to 16, which are various drawings of a one-handed operation type trigger device of the second embodiment of the present application. This embodiment has a partially identical structure with the first embodiment, so identical components are given identical symbols and their descriptions are omitted. The difference between this embodiment and the first embodiment is that the size of the pressing body 31 of this embodiment is larger than the size of the supporting member 21, so when the pressing assembly 30 is assembled to the base assembly 20, the second extension member 33 is farther away from the switch assembly 10 than the first extension member 22, that is, the first extension member 22 is located on the inner side of the second extension member 33. In addition, multiple abutment protrusions 41 are respectively arranged on multiple first extension members 22 and multiple abutment slots 42 are respectively arranged on multiple second extension members 33. Since the first extension member 22 is located on the inner side of the second extension member 33, the abutment protrusion 41 extends from the side of the abutment slot 42 close to the switch assembly 10 to the side away from the switch assembly 10, and the abutment protrusion 41 also abuts against the hole wall of the abutment slot 42 in the first direction L1. The abutment protrusion 41 of this embodiment abuts against the hole wall of the abutment slot 42 close to the support member 21, and there is a retreat distance between the end of the first extension member 22 and the pressing body 31.

[0065] like Fig.15 As shown, when the user applies force to one side of the pressing body 31, it is defined as the force side P1, and the side of the pressing body 31 opposite to the force side is defined as the abutment side P2. At least one abutment protrusion 41 of the abutment side P2 remains abutted against the hole wall of the abutment slot 42, so that the user can continue to increase the force and finally cause the abutment member 32 to push the first contact component 11 to move along the first direction L1 and contact the second contact component 12.

[0066] The one-handed operation type trigger device of the present application is provided with a plurality of first extensions on opposite sides of the support member of the base assembly, and a plurality of second extensions on opposite sides of the pressing body of the pressing assembly, wherein the plurality of first extensions correspond to the plurality of second extensions, and a position limiting and pressurizing mechanism is provided on the plurality of first extensions and the plurality of second extensions, and the plurality of abutting protrusions of the position limiting and pressurizing mechanism abut against the hole walls of the plurality of abutting slots respectively. When the user applies force to the force-applying side of one side of the pressing body, at least one abutting protrusion of the abutting side opposite to the force-applying side in the pressing body remains abutted against the hole wall of the abutting slot, and even if the force is applied to a position close to the edge of the pressing body, the force-applying side of the pressing body will not move directly until it is stopped by the support member, and the user can continue to increase the force and finally overcome the force required by the first contact member, so that the abutting member pushes the first contact member to move and contact the second contact member. In this way, the dead point of operation can be avoided in all directions and all-round triggering can be achieved.

[0067] The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
