Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from the embodiments given herein without making any creative effort shall fall within the protection scope of the present application. In addition, the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

The embodiment of the application provides a protection jig for protect when connecting piece is installed and removed electronic equipment and part thereof. The electronic device can be any product with communication and storage functions, including but not limited to a tablet computer, a mobile phone, an electronic reader, a remote controller, a notebook computer, a vehicle-mounted device, a network television, a wearable device, and the like. The components in the electronic device may be any parts such as a housing, a battery, a connector, a circuit board, etc.; or may be a preassembled assembly comprising several parts, such as a center frame assembly, a circuit board assembly, etc. Some parts of this electronic equipment and this part need assemble and dismantle connecting piece (including but not limited screw, nut etc.), and the vicinity of these parts often is the key position, or has arranged other key parts, need use the protection tool of this application to protect it. In the following description, the electronic apparatus and the component are collectively referred to as a "workpiece". The following detailed description is to be read with reference to the specific drawings.

As shown in fig. 1, the protective fixture 10 of the present embodiment may include a base 11, a first cover plate 12 and a second cover plate 13.

Specifically, the base 11 is used for bearing and clamping a workpiece. The surface of the base 11 is provided with a first clamping area 11a and a second clamping area 11b, when a workpiece is placed on the base 11, the first clamping area 11a is aligned with a mounting part of the workpiece, which is required to be provided with a connecting piece, and the second clamping area 11b is aligned with a key part of the workpiece, which is required to be protected (in fig. 1, a large dotted square on the base 11 represents the first clamping area 11a, and a small dotted square represents the second clamping area 11b, which is only an illustration. That is, in the subsequent process, the connecting piece is assembled and disassembled at the position of the workpiece in the first clamping area 11a, and the position of the workpiece in the second clamping area 11b is protected. The first clamping area 11a and the second clamping area 11b are adjacent to each other, and can be closely adjacent to each other to form a common boundary or have a certain distance therebetween. Preferably, the first clamping area 11a and the second clamping area 11b can be substantially coplanar, which corresponds to the situation that the mounting position of the workpiece is substantially coplanar with the key position (preferably, the workpiece is substantially flat-plate-shaped as a whole); alternatively, the first clamping area 11a and the second clamping area 11b may not be coplanar but have an included angle, which corresponds to a case where the mounting portion of the workpiece is connected to the critical portion not coplanar but with an included angle (in an extreme case, the workpiece is entirely curved).

As shown in fig. 1 and 2, the first cover 12 is mounted on the base 11 and forms an articulation with the base 11, including but not limited to sliding or rotating. The first cover plate 12 is movable relative to the base 11 to a position for covering the first clamping area 11a and is also movable in the opposite direction away from the first clamping area 11a to expose the first clamping area 11 a. Preferably, the first cover 12 is in a rotatable connection with the base 11. The first cover 12 may be pivotally connected to the base 11 by a hinge, for example, and the first cover 12 may be closed with the base 11 to cover the first clamping area 11a (in this case, the mounting portion of the workpiece is sandwiched between the first cover 12 and the base 11) or opened to expose the clamping area (in this case, the mounting portion of the workpiece is exposed). The first cover plate 12 is provided with a guide through hole 12b, the guide through hole 12b corresponds to the first clamping area 11a, and when the first cover plate 12 covers the first clamping area 11a, the guide through hole 12b is just positioned in the first clamping area 11a and aligned with the mounting through hole in the mounting part of the workpiece, so that the connecting piece is mounted in the mounting through hole through the guide through hole 12 b. The number of the guiding through holes 12b may be several, and the specific number and position may be designed as required.

As shown in fig. 1 and 2, the second cover 13 is movable relative to the base 11 and the first cover 12, and the second cover 13 may be movably connected to the base 11 or the first cover 12. The second cover 13 can be moved to a position to cover the second clamping area 11b (when the critical part of the workpiece is clamped between the second cover 13 and the base 11), or moved in the reverse direction away from the second clamping area 11b to expose the second clamping area 11b (when the critical part of the workpiece is exposed). The movement of the second cover plate 13 is independent of the movement of the first cover plate 12, i.e. they can move independently without mutual influence.

The second cover 13 is also movable to a position covering the second clamping area 11b when the first cover 12 covers the first clamping area 11 a. Thus, when a connector is attached to or detached from an attachment site of a workpiece through the guide through-hole 12b of the first cover plate 12, the second cover plate 13 covers a critical site on the workpiece so that the critical site is not affected by attachment/detachment operations of the connector (including, but not limited to, a possibility that the connector falls on the critical site during attachment/detachment, or that an attachment tool or a person may accidentally hit or scratch the critical site). In the process of assembling and disassembling the connecting piece, the connecting piece can not be installed in place or locked due to the reasons of sliding teeth, damage or low manufacturing precision and the like of the connecting piece. At this time, the first cover plate 12 can be opened to expose the first clamping position, so that the connecting piece on the workpiece can be conveniently detached and maintained by personnel. At the same time, the second cover plate 13 may continue to cover the second clamping area 11b to avoid the impact of maintenance work (including but not limited to the possibility that the connector may fall onto the critical portion during the disassembly process, or that the critical portion may be touched and scratched by an installation tool or a person).

The solution of the present embodiment is designed to have a first cover plate 12 movably connected to the base 11, and a second cover plate 13 moving relative to the base 11 and the first cover plate 12, wherein the first cover plate 12 and the second cover plate 13 move independently. When the connecting pieces need to be assembled and disassembled, the first cover plate 12 can be moved to the position of the first clamping area 11a on the sealing base 11 to cover the installation part of the workpiece, and the second cover plate 13 can be moved to the position of the second clamping area 11b on the sealing base 11 to cover the key part of the workpiece; when the first cover plate 12 needs to be opened for maintenance, the second cover plate 13 can continuously cover the second clamping area 11b so that the mounting position of the workpiece is covered. Due to the covering and protecting function of the second cover plate 13, even if the first cover plate 12 is opened, the key parts of the workpiece cannot be damaged or abnormal due to the influence of the assembly and disassembly operation of the connecting pieces.

Preferably, in one embodiment, as shown in fig. 1 and 2, the first cover 12 may have an installation notch 12c formed therein, and the installation notch 12c may penetrate the first cover 12 in a thickness direction of the first cover 12. The second cover 13 is disposed in the mounting notch 12c and can rotate relative to the base 11 and the first cover 12. The second cover 13 may be rotatably connected to the base 11 or rotatably connected to the first cover 12. Preferably, the second cover 13 is pivotally connected to the first cover 12 by a hinge or hinge. The position and assembly design of the second cover plate 13 and the first cover plate 12 not only matches the position of the key part inside the workpiece (for example, the middle frame assembly comprises a middle frame and a battery, and the battery is accommodated in the middle frame and is separated from the edge of the middle frame by a certain distance), but also facilitates the opening and closing of the protective jig 10 by personnel, and facilitates the assembly and disassembly operation of the connecting piece.

Unlike the above-described embodiment, in another embodiment, as shown in fig. 3, the first cover 12 does not need to have the installation notch 12c, and the first cover 12 and the second cover 13 are arranged side by side rather than being fitted. The first cover plate 12 can slide or rotate, and the second cover plate 13 can also slide or rotate. The design is also suitable for the specific structure of the workpiece and is convenient for the operation of personnel.

Further, as shown in fig. 4, the first cover plate 12 has a clamping surface 12a, and the clamping surface 12a faces the base 11 to be attached to the mounting portion of the workpiece when the first cover plate 12 covers the first clamping area 11 a. The mounting notch 12c penetrates the clamping surface 12 a. The clamping surface 12a may be provided with a limiting groove, and a side surface of the limiting groove is located at the periphery of the mounting notch 12c, i.e. the limiting groove surrounds the outside of the mounting notch 12 c. The inner cavity of the limiting groove may extend to communicate with the mounting notch 12c, or the limiting groove may be spaced apart from the mounting notch 12 c. The limiting groove is used for being clamped with the periphery of the second cover plate 13, so that the second cover plate 13 drives the first cover plate 12 to rotate away from the first clamping area 11 a. Preferably, for the scheme that the inner cavity of the limiting groove extends to be communicated with the installation notch 12c, a boss structure can be formed on the periphery of the second cover plate 13, and the boss structure is clamped with the bottom wall of the limiting groove. When the second cover plate 13 rotates away from the second clamping area 11b, the second cover plate 13 applies a pushing force to drive the first cover plate 12 to rotate away from the first clamping area 11 a. Or, for the scheme that the spacing groove is spaced from the mounting notch 12c, a bent portion may be formed at the periphery of the second cover plate 13, and the bent portion is inserted into the spacing groove to form a fit, so as to achieve the purpose that the second cover plate 13 drives the first cover plate 12 to rotate. Through the linkage structure, the second cover plate 13 can drive the first cover plate 12 to rotate, so that the protective jig 10 can be conveniently opened through one-time operation after the connecting piece is assembled, disassembled or maintained by personnel, and the working efficiency is improved. Of course, the movement of the first cover 12 and the second cover 13 can be completely independent, and at this time, the person needs to open the first cover 12 and the second cover 13 respectively.

Further, as shown in fig. 5 to 7, a guide bushing 14 may be installed in the guide through hole 12b of the first cover plate 12, and the guide bushing 14 is used for allowing the connection member to pass through and performing posture adjustment and guidance on the connection member. Specifically, as shown in fig. 5 and 6, the guide bush 14 may include an adjuster 141 and a guide 142, the adjuster 141 being connected to the guide 142 (the arc-shaped dotted line in fig. 5 indicates a boundary line between the adjuster 141 and the guide 142). The adjusting portion 141 has a first inner hole 141a, and the guiding portion 142 has a second inner hole 142a communicating with the first inner hole 141a, and the axis of the first inner hole 141a and the axis of the second inner hole 142a are both parallel to the guiding through hole 12 b. The first inner hole 141a has a larger diameter at an end thereof remote from the guide portion 142 than at an end thereof adjacent to the guide portion 142, i.e., the first inner hole 141a is a trapezoidal hole. The second inner hole 142a is a constant diameter hole, i.e., the radial dimension is uniform at each position in the axial direction of the second inner hole 142 a. As shown in fig. 7, when the first cover plate 12 covers the first clamping area 11a, the guide portion 142 is located between the adjusting portion 141 and the base 11, that is, the guide portion 142 is closer to the base 11 and the workpiece. When the workpiece is loaded into the wire guide bush, the workpiece first enters the first inner hole 141a of the adjusting portion 141 (it is understood that the diameter of the first inner hole 141a allows the workpiece to pass through), and due to the trapezoidal configuration of the first inner hole 141a, the workpiece is gradually adjusted in posture (e.g., adjusted from a skewed posture to a vertical posture) due to the force applied to the wall of the first inner hole 141a during the movement from the large end to the small end of the first inner hole 141 a. Eventually the workpiece will break free of the first bore 141a into the second bore 142a of the guide portion 142. The second inner hole 142a is used for guiding the connecting piece after the posture is adjusted, so that the connecting piece is aligned to the mounting through hole on the workpiece, and the connecting piece can be conveniently mounted by a person. By designing such a guide bush 14 with posture adjustment and guide functions, high-quality mounting of the connecting member can be achieved. Of course, the guide bushing 14 is not necessary. For example, the guide through hole 12b may be provided as a trapezoidal hole portion and a constant diameter hole portion instead of the guide bush 14. Alternatively, the guide through hole 12b may be a constant diameter hole.

Further, as shown in fig. 8, the base 11 may include a profiling portion 112 and a bearing portion 111, the profiling portion 112 is mounted on the bearing portion 111, and both the first clamping area 11a and the second clamping area 11b are areas in the profiling portion 112, that is, the profiling portion 112 is specifically used for clamping a workpiece. The contoured portion 112 may match the contour of the workpiece to allow the workpiece to be closely clamped therein. To avoid damage to the workpiece, the contoured portion 112 may be made of a relatively soft material, such as silicone, plastic, or rubber. The first cover plate 12 is movably connected to the bearing portion 111, and the second cover plate 13 can be movably connected to the bearing portion 111, or movably connected to the profiling portion 112, or movably connected to the first cover plate 12. Of course, the base 11 may be an integral component, and is not assembled from the profiling portion 112 and the bearing portion 111.

Further, as shown in fig. 8, a contour groove 112b is formed in each of the first clamping area 11a and the second clamping area 11b of the contour portion 112, and the workpiece is accommodated in the contour groove 112 b. The bottom wall of the contour groove 112b can be provided with a plurality of receiving channels 112a arranged at intervals. The receiving channels 112a may be arranged in parallel or in a regular pattern as required. The connecting members dropped during the operation can drop into the receiving channels 112a of the contour grooves 112b instead of being clamped between the workpiece and the contour portions 112, thereby preventing the workpiece from being damaged due to the pressing of the connecting members against the workpiece. In addition, the provision of the housing groove 112a also reduces the weight of the copying portion 112. Of course, the contour groove 112b and the receiving channel 112a are not essential.

As shown in fig. 9, the side wall of the contour groove 112b has a top surface 112c opposite to the bottom wall of the contour groove 112 b. Further, as shown in fig. 9 and 10, the protection jig may include a limiting member 15 for limiting the workpiece clamped in the contour groove 112 b. Specifically, the limiting member 15 may include a connecting portion 152 and a limiting portion 151, and the connecting portion 152 is connected to the limiting portion 151. Coupling portion 152 is coupled to a top surface 112c of contoured groove 112b to form a mating (including but not limited to a removable) connection, e.g., top surface 112c may form an attachment slot into which coupling portion 152 is inserted. One end of the limiting portion 151 departing from the connecting portion 152 extends into the contour groove 112b, i.e., protrudes from a side surface (a surface connected between the top surface 112c and the bottom wall) of the side wall of the contour groove 112b, so as to abut against the workpiece to realize limiting. The position-limiting portion 151 may be made of a material with low hardness, including but not limited to plastic, silicone, rubber, etc., so as to avoid damaging the workpiece. The specific structure of the limiting member 15 can be designed according to the needs, and is not limited to the structure shown in fig. 9 and 10. The limiting part 15 is arranged to enable the workpiece to be clamped stably and ensure that the workpiece is good in appearance. Of course, the stopper 15 is not essential.

Further, as shown in fig. 9 and 11, the top surface 112c of the contour groove 112b may be mounted with the crimping member 16, and the crimping member 16 is engaged with the connecting portion 152 to crimp the connecting portion 152 to the top surface 112 c. The crimp 16 can be removably coupled to the top surface 112 c. Of course, the crimp 16 is not required.

As shown in fig. 12 and 13, the base 11 further has a limiting region 11c (in the embodiment where the base 11 includes the profiling portion 112 and the bearing portion 111, the limiting region 11c is a region on the profiling portion 112), and the limiting region 11c is adjacent to (outside of) the first clamping region 11a and the second clamping region 11 b. The second cover plate 13 is provided with a limiting post 131 in a protruding manner, and the limiting post 131 corresponds to the limiting area 11 c. When the second cover plate 13 covers the second clamping area 11b, one end of the limiting column 131 departing from the second cover plate 13 abuts against the limiting area 11c, so that the second cover plate 13 is supported, and the second cover plate 13 is prevented from collapsing and crushing a workpiece. The number of the limiting columns 131 can be a plurality, and the positions can be designed according to requirements. Of course, the restraining posts 131 are not required.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive various equivalent modifications or substitutions within the technical scope of the present application, and these modifications or substitutions should be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
