Description

Technical Field

[0001] The invention relates to the technical field of handles, and in particular to a segmented deformable handle and a portable device. Background Art

[0002] Portable devices usually have a certain weight. In order to improve the convenience of using the portable devices, the portable devices are usually equipped with a handle for carrying the devices, such as a bag handle, an instrument handle, etc.

[0003] The handles currently used on portable devices are mainly divided into the following three categories: the first category is flexible and retractable handles, which are retractable handles with built-in flexible springs. They have the advantages of light weight and small size, but they cannot match the hand shape, resulting in a poor feel when used, and are easy to shake, with limited load-bearing capacity, and are not suitable for use with precision instruments and equipment with heavy weight; the second category is fixed handles, which have a better feel and a larger load-bearing capacity, but are large in size and occupy excessive equipment space, and are not suitable for small and medium-sized portable devices; the third category is foldable handles, which combine the advantages of the above two types of handles and can achieve large load-bearing capacity, small size, and good feel, but currently appear in the form of luggage handles made of plastic or cloth as raw materials, and cannot take into account the feel effects of users of different hand sizes at the same time, and are not suitable for use in precision instrument-type portable devices.

[0004] A Chinese patent document discloses "a luggage carrying handle", and its authorization announcement number is CN214340662U. The patent provides a luggage carrying handle that connects the mounting base and the connecting seat by a support rod through a first through hole and a second through hole in the horizontal direction, and plays a role in bearing vertical forces with high strength. However, the structure of the carrying handle cannot be adjusted according to users of different hand sizes, and a comfortable hand feeling effect cannot be guaranteed. In addition, the handle is large in size, occupies too much equipment space, and is not suitable for small and medium-sized portable devices. Summary of the invention

[0005] In view of the shortcomings of the prior art described above, an object of the present invention is to provide a segmented deformable handle and a portable device, which are used to solve the problems that the handles used on existing portable devices are large in size, occupy excessive device space, cannot match the hand shape, and are not suitable for use in portable devices such as precision instruments.

[0006] To achieve the above-mentioned object and other related objects, the present invention provides a segmented deformable handle, including a hand grip, a handle lifting structure, two pairs of handle swivels and handle seats sequentially arranged at both ends of the hand grip, one end of the handle swivel is rotatably connected to the handle seat, and the other end is slidably connected to the hand grip through the handle lifting structure, the handle lifting structure has an initial state and a lifting state, when the handle lifting structure is in the initial state, the hand grip, the handle swivel and the handle seat are in the same horizontal plane, when the handle lifting structure is in the lifting state, the hand grip and the handle swivel are lifted upward relative to the handle seat to form a gripping space.

[0007] In the above-mentioned technical scheme of the present application, the segmented deformable handle of the present application creatively adopts a handle lifting structure that can switch between the initial state and the lifting state at will. When the portable device does not need to be carried, the handle lifting structure is adjusted to the initial state. At this time, the hand grip, the handle swivel and the handle seat are in the same horizontal plane, which is suitable for use on small devices. It is more compact and takes up less space while taking into account the user experience, solving the problem that the handles used on existing portable devices are large in size and excessively occupy equipment space; when the portable device needs to be carried, the handle lifting structure is adjusted to the lifting state, the hand grip and the handle swivel are lifted upward relative to the handle seat to form a gripping space, which is suitable for application in portable devices such as precision instruments.

[0008] Preferably, the handle lifting structure includes a sliding groove and a sliding shaft arranged at both ends of the handle, and the two ends of the handle are respectively driven to lift and reciprocate relative to the two handle swivels through the sliding cooperation of the sliding shaft and the sliding groove along the length direction.

[0009] In the above technical solution of the present application, the sliding cooperation between the sliding shaft and the sliding groove along the length direction is used to realize the lifting reciprocating motion of the handle piece relative to the two handle swivels, forming a linkage relationship in which the handle swivel and the handle seat rotate relative to each other while the hand grip and the handle swivel slide relative to each other, so as to realize the rapid switching between the above initial state and the lifting state.

[0010] Preferably, the handle lifting structure further comprises an elastic reset member arranged in the hand grip, and both ends of the elastic reset member are respectively sleeved on two sliding shafts, and the elastic reset member is used to realize the automatic reset of the hand grip driven by the handle rotation.

[0011] The elastic reset part can increase the efficiency of reset and produce a comfortable hand feel. When the handle base is fixed on the instrument at a set distance, two relatively stable bases are formed. Since the elastic reset part always maintains the force to pull the two sliding shafts to the minimum distance, the sliding shaft automatically slides toward the center line of the two bases, and the pulling force at both ends is consistent. The sliding of the sliding shaft drives the handle swivel to rotate downward. This process is the process of automatic reset of the hand grip, and it is also the process of the hand grip from high to low distance from the handle base. When the user lifts the hand grip upward, the sliding shaft will slide along the slide groove on the hand grip to the outside of both ends, driving the handle swivel to rotate upward. The hand grip and the handle swivel are lifted upward relative to the handle base to form a gripping space, and finally form the shape and function of the handle.

[0012] Preferably, the segmented deformable handle also includes a lifting distance adjustment mechanism, which includes a limit block and an adjustment knob arranged below the sliding groove, and the blocking position of the limit block relative to the sliding groove is adjusted by rotating the adjustment knob in and out to adjust the sliding distance of the sliding shaft in the sliding groove.

[0013] Since users' hands vary in size, fatness, and thinness, the requirements for the gripping space of the handle will also vary. In the present application, the maximum lifting height of the grip is determined by the length of the internal slide groove. In the prior art, in order to meet the needs of users with larger hands, the lifting height of the grip is usually designed to be relatively high, but this may not be user-friendly for small hands. The present application designs a lifting distance adjustment mechanism, and adjusts the blocking position of the limit block relative to the slide groove based on the in and out rotation of the adjustment knob to adjust the sliding distance of the sliding shaft in the slide groove, thereby achieving adjustable gripping space, so that the handle can match the hand shape, and greatly improves the hand feel effect.

[0014] Preferably, an elastic fixing piece is provided between the limit block and the adjusting knob, the limit block is provided with an adjusting knob insertion hole, the adjusting knob has a plug-in portion adapted to the adjusting knob insertion hole, the plug-in portion has a step groove, and the elastic fixing piece is sleeved outside the step groove.

[0015] The elastic fixing piece can effectively fix the adjusting knob and improve the stability of the segmented deformable handle.

[0016] Preferably, the hand grip includes a hand grip upper cover and a hand grip lower cover which are interlocked with each other, the sliding groove is arranged at both ends of the hand grip upper cover, the hand grip lower cover is provided with an adjusting knob assembly hole, the adjusting knob passes through the adjusting knob assembly hole and the adjusting knob insertion hole in sequence and is fixed to the limit block, and the upper surface of the limit block is provided with a limit curved surface adapted to the sliding axis, which can better perform limiting.

[0017] Preferably, a sliding shaft assembly hole is provided at one end of the handle swivel close to the hand grip, and the sliding shaft passes through the sliding groove and the sliding shaft assembly hole to achieve a sliding connection between the hand grip and the handle swivel.

[0018] Preferably, strip grooves are provided on both sides of the handle swivel, the sliding shaft assembly hole is provided in the strip groove, and a sliding shaft limiting film is provided in the strip groove. The sliding shaft limiting film can contact with both ends of the sliding shaft to generate friction, which can produce a limiting effect on the one hand to improve the stability of the handle, and can effectively protect the sliding shaft to prevent damage and increase its service life on the other hand.

[0019] Preferably, a rotating shaft is provided between the handle swivel and the handle seat, a rotating shaft assembly hole is provided at one end of the handle swivel close to the handle seat, and a rotating shaft fixing block is provided on the handle seat. The rotating shaft passes through the rotating shaft assembly hole and is fixed by the rotating shaft fixing block to realize the rotational connection between the handle swivel and the handle seat.

[0020] The present invention also provides a portable device, comprising the above-mentioned segmented deformable handle.

[0021] As described above, the segmented deformable handle and portable device of the present invention have the following beneficial effects: (1) A handle lifting structure that can switch between an initial state and a lifting state at will is adopted. When the portable device does not need to be carried, the handle lifting structure is adjusted to the initial state. At this time, the hand grip, the handle swivel and the handle base are on the same horizontal plane, which is suitable for use on small devices. The volume is more compact, and less space is occupied while taking into account the user experience. When the portable device needs to be carried, the handle lifting structure is adjusted to the lifting state, and the hand grip and the handle swivel are lifted upward relative to the handle base to form a gripping space; (2) By designing a lifting distance adjustment mechanism, the blocking position of the limit block relative to the slide groove is adjusted based on the inward and outward rotation of the adjustment knob, so as to adjust the sliding distance of the sliding shaft in the slide groove, thereby achieving adjustable gripping space, so that the handle can match the hand shape, and the hand feel effect is greatly improved; (3) The segmented deformable handle of the present application takes into account the two major requirements of good handle feel and small size, and at the same time adds an adjustable handle lifting height function to enhance the user experience.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] like Figure 1 As shown, the embodiment of the present application provides a segmented deformable handle, including a grip 1, a handle lifting structure, a lifting distance adjustment mechanism, two pairs of handle swivels 2 and handle seats 3 sequentially arranged at both ends of the grip, as shown in FIG. Figure 3 As shown, the hand grip comprises a hand grip upper cover 17 and a hand grip lower cover 18 that are interlocked, one end of the handle swivel is rotatably connected to the handle seat, and the other end is slidably connected to the hand grip through a handle lifting structure, and the handle lifting structure has an initial state and a lifting state. When the handle lifting structure is in the initial state, the hand grip, the handle swivel and the handle seat are in the same horizontal plane, and when the handle lifting structure is in the Figure 2 In the lifting state shown, the hand grip and the handle swivel are lifted upward relative to the handle seat to form a gripping space. The lifting distance adjustment mechanism is used to adjust the lifting height of the hand grip to match the hand shape.

[0034] like Figure 3~Figure 7 As shown, the handle lifting structure includes a slide groove 11, a slide shaft 12 and an elastic reset member 13 provided at both ends of the upper cover of the handle, and the lower cover of the handle is provided with an adjustment knob assembly hole 181, as shown in FIG. Figure 7 As shown, the two ends of the elastic reset member are respectively sleeved on the two sliding shafts, and the elastic reset member is used to realize the automatic reset of the handle swivel and the hand grip. The two ends of the hand grip drive the hand grip to perform lifting and reciprocating motion relative to the two handle swivels through the sliding cooperation of the sliding shaft and the sliding groove along the length direction. The end of the handle swivel close to the hand grip is provided with a sliding shaft assembly hole 21, and the sliding shaft passes through the sliding groove and the sliding shaft assembly hole to realize the sliding connection between the hand grip and the handle swivel. The two sides of the handle swivel are provided with strip grooves 22, and the sliding shaft assembly hole is provided in the strip groove, and the strip groove is provided with a sliding shaft limiting film 23. A rotating shaft 24 is provided between the handle swivel and the handle seat, and a rotating shaft assembly hole 25 is provided at the end of the handle swivel close to the handle seat, and the handle seat is provided with a rotating shaft fixing block 31, and the rotating shaft passes through the rotating shaft assembly hole and is fixed by the rotating shaft fixing block to realize the rotating connection between the handle swivel and the handle seat.

[0035] like Figure 7As shown, the lifting distance adjustment mechanism includes a limit block 14 and an adjustment knob 15 arranged below the slide groove. The limit block is adjusted relative to the slide groove by rotating the adjustment knob in and out to adjust the sliding distance of the slide shaft in the slide groove. An elastic fixing member 16 is arranged between the limit block and the adjustment knob. The limit block is provided with an adjustment knob insertion hole. The adjustment knob has a plug-in portion 151 adapted to the adjustment knob insertion hole. The plug-in portion has a step groove 152. The elastic fixing member is sleeved outside the step groove. The adjustment knob passes through the adjustment knob assembly hole and the adjustment knob insertion hole in sequence and is fixed to the limit block. The adjustment knob is installed on the lower cover of the hand grip by means of an elastic fixing member. The built-in limit block is connected with the large pitch of the adjustment knob. The rotation of the adjustment knob can lift the limit block longitudinally. When the limit block is lifted upward, it can block part of the slide groove, thereby shortening the length of the slide groove and reducing the lifting height of the hand grip.

[0036] Specifically, the elastic reset member is a telescopic spring, and the elastic fixing member is a clip spring.

[0037] The embodiment of the present application also provides a portable device, including the above-mentioned segmented deformable handle, wherein the handle base is provided with mounting screw holes, and can be directly fixed to the portable device using the mounting screw holes and fasteners.

[0038] The working principle of this embodiment is as follows: When the portable device does not need to be carried, the handle lifting structure is adjusted to Figure 1 In the initial state shown, the slide shaft is at one end of the slide groove close to the handle. At this time, the handle, the handle swivel and the handle seat are at the same horizontal plane, with a compact structure and small space occupation; When the portable device needs to be carried, the handle lifting structure is adjusted to Figure 2 In the lifting state shown, the sliding shaft slides along the sliding groove toward the outer sides of both ends, driving the handle rotating body to rotate upward, so that the hand grip and the handle rotating body are lifted upward relative to the handle seat to form a gripping space, and finally form the shape and function of the handle; After the handle base is fixed on the instrument at a set distance, two relatively stable bases are formed. Since the elastic reset member always maintains the force to pull the two sliding shafts to the minimum distance, when the portable device needs to be reset when it is no longer needed, the user only needs to release the lifting force, and the elastic potential energy of the elastic reset member drives the sliding shaft to automatically slide toward the center line of the two bases, and the pulling force at both ends is consistent. The sliding of the sliding shaft drives the handle swivel to rotate downward, and the distance between the hand grip and the handle base decreases from high to low. The hand grip, the handle swivel and the handle base are finally on the same horizontal plane, completing the automatic reset.

[0039] In summary, the present invention adopts a handle lifting structure that can switch between the initial state and the lifting state at will. When the portable device does not need to be carried, by adjusting the handle lifting structure to the initial state, the hand grip, the handle swivel and the handle seat are in the same horizontal plane, which is suitable for use on small devices, and the volume is more compact, taking up less space while taking into account the user experience; when the portable device needs to be carried, by adjusting the handle lifting structure to the lifting state, the hand grip and the handle swivel are lifted upward relative to the handle seat to form a gripping space; by designing a lifting distance adjustment mechanism, the blocking position of the limit block relative to the slide groove is adjusted based on the rotation in and out of the adjustment knob to adjust the sliding distance of the sliding shaft in the slide groove, so as to achieve the adjustable size of the gripping space, so that the handle can match the hand shape, greatly improving the hand feeling effect; the segmented deformable handle of the present application takes into account the two major requirements of good handle feel and small volume, and at the same time increases the function of adjustable handle lifting height, which enhances the user experience. Therefore, the present invention effectively overcomes the various shortcomings in the prior art and has a high industrial utilization value.

[0040] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
