Description

Technical Field

[0001] This utility model relates to the field of audio processor technology, and more specifically, to a combined button support frame and an audio processor. Background Technology

[0002] An audio processor is an electronic device used to process audio signals. Currently, audio processors on the market mainly consist of a housing, a PCB board, a soft rubber keyboard, and a key support frame. The PCB board, soft rubber keyboard, and key support frame are stacked sequentially from bottom to top inside the housing and fastened to it. The key support frame is used to fit over the outside of each key on the soft rubber keyboard and to provide lateral support for the keys. However, in the existing audio processor structure, the shape of the key support frame used in the audio processor is designed according to the shape of the soft rubber keyboard. That is, when the shape or layout of the soft rubber keyboard changes, the shape and layout of the key support frame also need to be changed accordingly. This requires redesigning the key support frame and the mold used for injection molding the key support frame, resulting in high product design and manufacturing costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a combined key support frame and audio processor, wherein the internal support frame units can be freely spliced ​​according to the design and layout of the soft rubber keyboard to form a key support frame that is compatible with the soft rubber keyboard.

[0004] This utility model provides a combined key support frame, comprising a plurality of support frame units arranged in an array, wherein adjacent support frame units are spliced ​​together to form a key support frame; each support frame unit has a first male connection end formed at its right end and a first female connection end formed at its left end, the first male connection end and the first female connection end being vertically fitted together to limit the horizontal movement of adjacent support frame units; each support frame unit has a second male connection end formed at its rear end and a second female connection end formed at its front end, the second male connection end and the second female connection end being vertically fitted together to limit the horizontal movement of adjacent support frame units; each support frame unit has at least one through hole vertically provided, the through hole being for one of the keys located on the soft rubber keypad to pass through from bottom to top.

[0005] By adopting the above structure, this utility model allows several support frame units to be freely spliced ​​and combined according to the shape or layout of the soft rubber keyboard, so that the assembled key support frame can be adapted to different types of soft rubber keyboards. Therefore, when the shape or layout of the soft rubber keyboard is changed, there is no need to repeatedly develop and design the key support frame, and there is no need to redesign the mold for injection molding the key support frame, thereby reducing the design and manufacturing costs of the product.

[0006] In one possible implementation, each support frame unit is provided with two through holes spaced apart from each other on the left and right. With this structure, after several support frame units arranged in an array are spliced ​​together to form a key support frame, provided that the key support frame is adapted to a soft rubber keyboard, a single support frame unit can allow two keys on the soft rubber keyboard to pass through from bottom to top. Thus, for the same type of soft rubber keyboard, while ensuring that the support frame units can be freely spliced, the number of support frame units can be reduced, thereby making it convenient to splice several support frame units to form a key support frame.

[0007] In one possible implementation, a first dovetail block protruding outward is provided at the middle of the right end of the support frame unit, forming the first male connecting end of the support frame unit. A first dovetail groove concave inward is provided at the middle of the left end of the support frame unit, forming the first female connecting end of the support frame unit. The first dovetail block on the support frame unit is vertically engaged with the first dovetail groove on the adjacent support frame unit. With this structure, after the first dovetail block on the support frame unit is vertically engaged with the first dovetail groove on the adjacent support frame unit, the two adjacent support frame units on the left and right can be reliably connected together and achieve the purpose of horizontal limiting, and have the advantage of good anti-detachment effect of the two adjacent support frame units on the left and right.

[0008] In one possible implementation, the rear end of the support frame unit is provided with at least one outwardly protruding second dovetail block, which forms the second male connection end of the support frame unit; the front end of the support frame unit is provided with a second dovetail groove that corresponds one-to-one with the second dovetail block, which forms the second female connection end of the support frame unit; the second dovetail block on the support frame unit is vertically engaged with the second dovetail groove on the adjacent support frame unit; by adopting this structure, after the second dovetail block on the support frame unit is vertically engaged with the second dovetail groove on the adjacent support frame unit, the two adjacent support frame units can be reliably connected together and achieve the purpose of horizontal limiting, and have the advantage of good anti-detachment effect of the two adjacent support frame units.

[0009] In one possible implementation, the rear end of the support frame unit is provided with two left-right symmetrical second dovetail blocks, and the front end of the support frame unit is provided with two left-right symmetrical second dovetail grooves. The two second dovetail blocks on the support frame unit are vertically engaged with the two second dovetail grooves on the adjacent support frame unit. By adopting this structure, the two second dovetail blocks on each support frame unit can be vertically engaged with the two second dovetail grooves on the adjacent support frame unit, thereby further improving the firmness and reliability of the connection between the two adjacent support frame units, that is, further improving the anti-detachment effect of the two adjacent support frame units.

[0010] In one possible implementation, an annular chamfered surface is provided on the inner wall at the lower end of each through hole. The annular chamfered surface is used to guide the key by engaging with the outer wall of the key so that the key can pass through the through hole from bottom to top. By providing an annular chamfered surface on the inner wall at the lower end of each through hole, when the key support frame formed by splicing several support frame units together is assembled with the soft rubber keyboard, the annular chamfered surface can engage with the outer wall of the key to guide the key to pass through the through hole from bottom to top, thus facilitating the assembly of the support frame unit or key support frame with the soft rubber keyboard.

[0011] In one possible implementation, the left end of the support frame unit has two symmetrically arranged protrusions, each with a first fixing hole vertically arranged on it; the right end of the support frame unit has two symmetrically arranged support steps, each with a second fixing hole vertically arranged at its bottom; the two protrusions on each support frame unit are supported on the two support steps on the adjacent support frame unit, and the first and second fixing holes are used for screws to pass through to fix the button support frame to the housing of the audio processor; by adopting this structure, after several support frame units are spliced ​​together to form the button support frame, the button support frame can be fixed to the housing of the audio processor by screws passing through the first and second fixing holes, which has the advantage of high reliability in fixing the button support frame to the housing of the audio processor.

[0012] An audio processor includes a housing, a PCB board, and a soft rubber keypad. The audio processor also includes the aforementioned combined key support frame. The PCB board, soft rubber keypad, and combined key support frame are stacked sequentially from bottom to top inside the housing and fastened to the housing. With this structure, the combined key support frame can be reliably used in the audio processor. In the above structure, the combined key support frame, soft rubber keypad, and PCB board are together fixed inside the housing by a number of screws. In addition, the combined key support frame is used to press the soft rubber keypad and PCB board onto the housing. Attached Figure Description

[0017] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] See Figure 1-4 As shown in the figure, this application discloses a combined key support frame, including a plurality of support frame units 1 arranged in an array. Adjacent support frame units 1 are spliced ​​together to form a key support frame. Each support frame unit 1 has a first male connection terminal on its right end and a first female connection terminal on its left end. The first male connection terminal and the first female connection terminal are vertically fitted together to limit the horizontal movement of adjacent support frame units 1. Each support frame unit 1 has a second male connection terminal at its rear end and a second female connection terminal at its front end. The second male connection terminal and the second female connection terminal are vertically fitted together to limit the horizontal movement of adjacent support frame units 1. Each support frame unit 1 has at least one through hole 11 vertically provided. The through hole 11 is used for one of the keys 21 located on the soft rubber keypad 2 to pass through from bottom to top.

[0019] Each support frame unit 1 is provided with two through holes 11 spaced apart from each other on the left and right. By adopting this structure, after several support frame units arranged in an array are spliced ​​together to form a key support frame, under the premise that the key support frame is adapted to the soft rubber keyboard, a single support frame unit can allow two keys on the soft rubber keyboard to pass through from bottom to top. Thus, for the same type of soft rubber keyboard, while ensuring that the support frame units can be freely spliced, the number of support frame units can be reduced, thereby making it convenient to splice several support frame units to form a key support frame.

[0020] A first dovetail block 12 protruding outward is provided at the middle of the right end of the support frame unit 1, forming the first male connecting end of the support frame unit 1. A first dovetail groove 13 concave inward is provided at the middle of the left end of the support frame unit 1, forming the first female connecting end of the support frame unit 1. The first dovetail block 12 on the support frame unit 1 is vertically engaged with the first dovetail groove 13 on the adjacent support frame unit 1. With this structure, after the first dovetail block on the support frame unit is vertically engaged with the first dovetail groove on the adjacent support frame unit, the two adjacent support frame units on the left and right can be reliably connected together and achieve the purpose of horizontal limiting, and have the advantage of good anti-detachment effect of the two adjacent support frame units on the left and right.

[0021] The rear end of the support frame unit 1 is provided with at least one outwardly protruding second dovetail block 14, which forms the second male connection end of the support frame unit 1; the front end of the support frame unit 1 is provided with a second dovetail groove 15 that corresponds one-to-one with the second dovetail block 14, which forms the second female connection end of the support frame unit 1; the second dovetail block 14 on the support frame unit 1 is vertically engaged with the second dovetail groove 15 on the adjacent support frame unit 1; by adopting this structure, after the second dovetail block on the support frame unit is vertically engaged with the second dovetail groove on the adjacent support frame unit, the two adjacent support frame units can be reliably connected together and achieve the purpose of horizontal limiting, and have the advantage of good anti-detachment effect of the two adjacent support frame units.

[0022] The rear end of the support frame unit 1 is provided with two second dovetail blocks 14 arranged symmetrically from left to right, and the front end of the support frame unit 1 is provided with two second dovetail grooves 15 arranged symmetrically from left to right. The two second dovetail blocks 14 on the support frame unit 1 are vertically fitted with the two second dovetail grooves 15 on the adjacent support frame unit 1. By adopting this structure, the two second dovetail blocks on each support frame unit can be vertically fitted with the two second dovetail grooves on the adjacent support frame unit, thereby further improving the firmness and reliability of the connection between the two adjacent support frame units, that is, further improving the anti-detachment effect of the two adjacent support frame units.

[0023] Each through hole 11 has an annular chamfered surface 111 on its inner wall at the lower end. The annular chamfered surface 111 is used to guide the key 21 to pass through the through hole 11 from bottom to top. By providing an annular chamfered surface on the inner wall at the lower end of each through hole, when the key support frame formed by splicing several support frame units together is assembled with the soft rubber keyboard, the annular chamfered surface can guide the key to pass through the through hole from bottom to top, which can facilitate the assembly of the support frame unit or the key support frame with the soft rubber keyboard.

[0024] The left end of the support frame unit 1 has two symmetrical protrusions 16, each with a vertically arranged first fixing hole 161. The right end of the support frame unit 1 has two symmetrically arranged support steps 17, each with a vertically arranged second fixing hole 171 at its bottom. The two protrusions 16 on each support frame unit 1 are supported on the two support steps 17 on the adjacent support frame unit 1. The first fixing hole 161 and the second fixing hole 171 are used for screws to pass through to fix the button support frame to the housing of the audio processor. With this structure, after several support frame units are spliced ​​together to form the button support frame, the button support frame can be fixed to the housing of the audio processor by screws passing through the first fixing hole and the second fixing hole. This has the advantage of high reliability in fixing the button support frame to the housing of the audio processor. In addition, after the protrusions are supported on the support steps, the first fixing hole and the second fixing hole can be vertically aligned and coaxially arranged, which facilitates the screw shank to pass through the first fixing hole and the second fixing hole.

[0025] An audio processor includes a housing 3, a PCB board 4, and a soft rubber keypad 2. The audio processor also includes the aforementioned combined key support frame. The PCB board 4, the soft rubber keypad 2, and the combined key support frame are stacked sequentially from bottom to top inside the housing 3 and fastened to the housing 3. With this structure, the combined key support frame can be reliably used in the audio processor. In the above structure, the combined key support frame, the soft rubber keypad, and the PCB board are fixed together inside the housing by a number of screws. In addition, the combined key support frame is used to press the soft rubber keypad and the PCB board onto the housing.

[0026] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
