The electronic device may be any product having a detachable structure, and for clarity of explanation of the product structure, the electronic device 100 is taken as an example of a remote controller in the present application.

Referring to fig. 1 to 5, the electronic device 100 includes a rear cover 110, a mount 120, a stopper assembly, a front cover 140, and a battery 150.

In the present application, the mounting of the rear cover 110 to the mounting base 120 is mainly concerned.

At least two sets of limiting components are designed for limiting the separation of the rear cover 110 from the mounting seat 120, so that in-place mounting is realized.

Wherein at least one group of spacing subassembly includes elastic component, receiving groove and installation cavity, and elastic component sets up in the installation cavity.

Since the in-place installation between the rear cover 110 and the mounting seat 120 is required to be realized in the present application, and thus, the cooperation between the receiving groove and the elastic component is involved, the receiving groove may be disposed on the rear cover 110 or on the mounting seat 120, and when the receiving groove is disposed on the rear cover 110, the corresponding mounting cavity is formed on the mounting seat 120; when the receiving groove is provided on the mount base 120, a corresponding mounting cavity is formed on the rear cover 110. As follows, the following description will be given taking an example in which the receiving groove is formed in the rear cover 110 and the mounting cavity is formed in the mounting seat 120.

Referring to fig. 2, the rear cover 110 includes a cover plate 111, the cover plate 111 having an arc shape as a whole, and receiving grooves 1111 (see fig. 5) are formed on inner sidewalls of the arc-shaped cover plate 111.

In the present application, the receiving groove 1111 is a circular arc groove.

Correspondingly, referring to fig. 1, 3 to 5, a mounting cavity 121 is opened on the mounting seat 120.

When the rear cover 110 is mounted in place, i.e., completely mounted to the mounting seat 120, the mounting cavity 121 is shielded by the rear cover 110, see fig. 5, and when the rear cover 110 is detached from the mounting seat 120, see fig. 2, the mounting cavity 121 is exposed.

Referring to fig. 5, elastic member 130 is disposed in mounting cavity 121 and is capable of extending and contracting in a depth direction of mounting cavity 121, such that elastic member 130 retracts toward a bottom of mounting cavity 121 when being compressed, and extends toward a top of mounting cavity 121 and a top of elastic member 130 extends out of mounting cavity 121 when elastic member 130 is reset.

The portion of the elastic member 130 protruding out of the mounting cavity 121 corresponds to the position of the receiving groove 111 of the rear cover 110.

Two sets of position-limiting assemblies are used as an example to describe how to limit the rear cover 110 to separate from the mounting seat 120.

The two groups of limiting components are not marked with a first group of limiting components and a second group of limiting components.

The first set of stop assemblies includes the resilient assembly 130, the mounting cavity 121, and the receiving slot 111 as described above.

The second set of stop assemblies may take a variety of forms to assist the first set of stop assemblies in stopping.

In the first embodiment, the second set of position-limiting components has the same structure as the first set of position-limiting components, but the elastic components are different in the extension and contraction direction of the mounting cavity, so as to ensure that the rear cover 110 cannot be separated from the mounting seat 120 in the Y direction and the Z direction shown in fig. 1.

The mounting cavities in the first set of limiting components and the mounting cavities in the second set of limiting components may be disposed on the left and right sides of the mounting cavities, with the corresponding internally disposed resilient components extending away from the mounting base 120 or retracting toward the mounting cavity 12.

The depth direction of the installation cavity in the first group of limiting assemblies and the depth direction of the installation cavity in the second group of limiting assemblies can form an obtuse angle and the like at an angle of 180 degrees.

Thus, when the two elastic members are correspondingly engaged with the two receiving grooves, the two elastic members have different expansion and contraction directions, and therefore, have component forces acting in the Y direction and the Z direction, respectively, and prevent the rear cover 110 from being separated in the Y direction and the Z direction in fig. 1.

In a second embodiment, the second set of position-limiting components includes a snap (not shown) formed at the top end of the elastic component 130 and a slot (not shown) formed in the mounting groove 1111.

After the rear cover 110 is installed, the top end of the elastic component 130 is embedded into the receiving groove 1111, and meanwhile, the buckle is in clamping fit with the clamping groove, so that the elastic component 130 and the receiving groove 1111 are installed in place.

At this time, the rear cover 110 is mounted in place on the mounting seat 120.

In a third embodiment, the second set of position limiting components includes a first position limiting portion and a second position limiting portion engaged with the first position limiting portion.

The first stopper portion may be formed on one of the rear cover 110 and the mount 120, and correspondingly, the second stopper portion may be formed on the other of the rear cover 110 and the mount 120.

The first limiting part and the second limiting part are matched to realize the guiding of the rear cover 110 relative to the mounting base 120 in the sliding process, and limit the rear cover 110 to be separated along the direction different from the sliding direction in the sliding process of the mounting base 120 and when the rear cover 110 is mounted in place. Referring to fig. 1 and 2, when the rear cap 110 is slidably pushed along the mounting seat 120 in the Y direction, the inner sidewall of the cover plate 111 first compresses the top end of the elastic member 130 and continues to push until the top end of the elastic member 130 is inserted into the receiving groove 1111, and then the rear cap 110 is mounted in place, at which time the rear cap 110 cannot move in the Y direction.

Due to the cooperation of the first and second position-limiting parts, the rear cover 110 is prevented from being separated along the Z direction in fig. 1 after being installed in place.

In the process of pushing the rear cover 110 to mount, the rear cover 110 presses the elastic component 130, so that the user has certain hand feeling, when the top end of the elastic component 130 is embedded into the receiving groove 1111, the insertion feeling similar to 'click' can be fed back to the user, and the size of the clamping force can be adjusted by adjusting the elastic force of the elastic component 130.

When the rear cap 110 is disassembled, the user presses the rear cap 110 and pushes the rear cap in the opposite direction of the Y-axis, so that the elastic member 130 is pressed to retract until the elastic member comes out of the receiving groove 1111, and the first and second position-limiting portions are disengaged, thereby separating the rear cap 110 from the mounting base 120, and disassembling the rear cap 110.

The structures of the elastic member 130, the first stopper portion, and the second stopper portion are described in detail as follows.

The elastic member 120 includes a guide member and an elastic member, the elastic member provides a force to the guide member toward the receiving groove 1111, and when the rear cover 110 is mounted in place, a tip of the guide member protrudes into the mounting cavity 121.

The elastic member may be a compression spring or a spring sheet, the bottom end of the elastic member is fixed to the bottom of the mounting cavity 121 by gluing, for example, or the bottom end of the elastic member abuts against the bottom of the mounting cavity 121, and the guiding member is fixed to the top end of the elastic member by gluing, for example.

The manner of cooperation between the elastic member and the guide member may also be other manners, which are not exhaustive here.

In the present application, referring to fig. 3 to 5, the elastic assembly 130 includes a spring 131 and a guide 132.

The guide portion 132 includes a guide post 1321, a guide cap 1322, and a stopper.

Referring to fig. 3 and 5, guide post 1321 is butted vertically at an intermediate position at the bottom of guide cap 1322; the stoppers are provided with two stoppers 1323/1323' symmetrically arranged on both sides of the guide cap 1322, or other numbers of stoppers may be provided.

Referring to fig. 5, the spring 131 telescopically fits over the guide post 1321.

The guide cap 1322 has a circular arc shape on the entire outer side wall thereof so as to be easily engaged with the receiving groove 1111 when the rear cover 110 is slidably mounted along the Y-axis.

Referring to fig. 3 and 5, the guide cap 1322 and the guide post 1321 form a T-shaped structure such that when the spring 131 is fitted over the guide post 1321, the top end of the spring 131 abuts against the bottom surface of the guide cap 1322 and the bottom end abuts against the bottom of the mounting cavity 121.

Alternatively, the guiding cap 1322 may be a rounded portion formed above the guiding post 1321, so that when the spring 131 is sleeved on the guiding post 1321, the top end of the spring 131 abuts against the bottom of the limiting block 1323/1323', and the bottom end of the spring 131 still abuts against the bottom of the mounting cavity 121.

Either way, the spring 131 is compressed when the guide cap 1322 is pressed.

When the guide cap 1322 is pressed, the spring 131 is compressed; when spring 131 is reset, guide cap 1322 is caused to extend, and a portion of guide cap 1322 extends out of mounting cavity 121.

To reduce the weight of elastomeric assembly 130, guide post 1321 and/or guide cap 1322 may each be hollow, see fig. 5.

In the present application, the cross-sectional area of the guide post 1321 is circular.

In order to limit the elastic component 130 in the mounting cavity 121 and enable the elastic component 130 to stretch and contract in the mounting cavity 121 without separating from the mounting cavity 121, the mounting cavity 121 may be designed as a convex cavity with a step portion.

The stopper 1323/1323' abuts against the bottom wall of the step, and the guide 130 moves toward the bottom of the mounting chamber 121 and compresses the spring 131 when the guide cap 1322 is pressed.

When the elastic assembly 130 is installed, the spring 131 is firstly sleeved on the guide column 1321, and then the whole body is pressed into the installation cavity 121 until the limiting block 1323/1323' abuts against the bottom wall of the step 1211, so that the installation is completed.

To facilitate mounting of the resilient assembly 130, referring to fig. 3 and 5, the circumferential inner side wall of the uppermost portion of the mounting cavity 121 forms a first inclined surface K1 that diverges from bottom to top.

Correspondingly, the corner of the bottom end of the limiting block 1323/1323' close to the outer side is cut off to form a second inclined surface K2/K2' consistent with the inclined direction of the first inclined surface K2, so that when the elastic component 130 is installed, the limiting block 1323/1323' is conveniently deformed by the contact interference of the first inclined surface K1 and the second inclined surface K2'/K2, and the limiting block 1323/1323' abuts against the bottom wall of the stepped part through the restoration of the corner of the stepped part.

When spring 131 is reset, the elastic force of spring 131 moves guide 130 toward the top of mounting cavity 121 and stops moving when stopper 1323/1323' contacts the bottom wall of the step, limiting spring assembly 130 from falling out of mounting cavity 121, and guide cap 1322 partially protrudes out of mounting cavity 121.

In the present application, referring to fig. 5, at least one sliding groove is formed on an inner sidewall of the mounting cavity 121 in a depth direction of the mounting cavity 121.

The number of the sliding grooves is the same as that of the stoppers on the guide portion 130, and the sliding grooves are used for guiding the movement of the stoppers in the Z direction and limiting the rotation of the elastic assembly 120 in the mounting cavity 121.

In the present application, the limiting blocks 1323'/1323 are provided, and therefore, the first sliding groove 1211 and the second sliding groove 1212 are correspondingly provided.

Referring to fig. 5, when the guide cap 1322 is pressed, the stopper 1323' is guided downward in the first slide groove 1211, and the stopper 1323 is guided downward in the second slide groove 1212, compressing the spring 131.

When the spring 131 is reset, the elastic force of the spring 131 causes the stopper 1323 'to be guided upward in the first sliding slot 1211, the stopper 1323 is guided upward in the second sliding slot 1212, and the guiding movement is stopped until the stoppers 1323'/1323 abut against the top wall of the first sliding slot 1211 and the top wall of the second sliding slot 1212, so as to prevent the spring assembly 130 from coming out of the mounting cavity 121, and at this time, the guiding cap 1322 partially protrudes out of the mounting cavity 121.

When the limiting blocks 1323'/1323 are respectively guided along the first sliding slot 1211 and the second sliding slot 1212, the circumferential side walls of the first sliding slot 1211 and the second sliding slot 1212 prevent the limiting blocks 1323'/1323 from rotating, so that the limiting blocks 1323'/1323 are stabilized in the mounting cavity 121. The first and second position-limiting portions may be constructed in various forms to prevent the rear cover 110 from being separated in the Z direction after being mounted in place.

The structure of the first stopper portion and the second stopper portion is exemplified as follows.

The first position-limiting portion may be at least one set of slide ways that are folded inwards and arranged on two side edges of the rear cover 110.

Correspondingly, the second limiting portion is formed by at least one set of sliding blocks disposed on two side edges of the mounting base 120, and each set of sliding blocks is matched with each set of sliding ways.

The first position-limiting portion may be a set of whole slide ways along the length direction of the rear cover 110 and on the two side edges of the rear cover 110, or may be a plurality of sets of slide ways formed by a plurality of sets of hooks distributed at intervals, for example, fig. 2 shows a plurality of sets of slide ways formed by three sets of hooks distributed at intervals, in which only the hooks 113 of one set of hooks are marked, and fig. 5 shows the hooks 113' of one set of hooks opposite to the hooks 113.

Correspondingly, the second limiting portion may be a set of entire sliders on two side edges of the mounting seat 120 along the length direction of the mounting seat 120, or may be a plurality of sets of sliders distributed at intervals, for example, three sets of sliders distributed at intervals are shown in fig. 2, where only the slider 122 in one set of sliders is marked.

When the first limiting part is the whole slide way, one group of whole slide blocks or a plurality of groups of slide blocks slide along the whole slide way when the rear cover 110 is installed in a sliding way.

When the first limiting part is a plurality of groups of slide ways formed by a plurality of groups of hooks, if the second limiting part is a group of whole slide blocks, the group of whole slide blocks slide along the plurality of groups of slide ways when the rear cover 110 is installed in a sliding way; if the second limiting portion is a plurality of sets of sliding blocks, each set of sliding blocks is arranged corresponding to each set of sliding ways, when the rear cover 110 is installed in a sliding mode, the sliding blocks slide along the sliding ways, and when the rear cover 110 is installed in place, each sliding way is correspondingly matched with each sliding block to limit the rear cover 110 to be separated in the Z direction.

Alternatively, there are many ways to slidably fit the rear cover 110 and the mounting seat 120, such as fitting a U-shaped (T-shaped) protrusion and a U-shaped (T-shaped) sliding groove.

In the present application, for the purpose of lightening, facilitating the machining and reducing the wear degree between the mounting seat 120 and the rear cover 110 when slidably mounted, referring to fig. 2, at least one set of slide ways includes a plurality of sets of hooks distributed at intervals, and at least one set of slide blocks includes a plurality of sets of slide blocks distributed at intervals, and each set of slide blocks is correspondingly matched with each set of slide ways.

Through the cooperation of the elastic component 130, the slide way and the slide block, the rear cover 110 is convenient to disassemble, the abrasion degree between the rear cover 110 and the mounting seat 120 is reduced, and the service life of parts is prolonged; in addition, during assembly, the accuracy requirements on the rear cover 110 and the mounting seat 120 are low, which is beneficial to realizing the consistency of product quality, thereby improving the product yield.

In this application, referring to fig. 1 and fig. 2, since the electronic device 100 is exemplified as a remote controller and the mounting base 120 is a middle shell, for aesthetic reasons, when the rear cover 110 is mounted on the mounting base 120, the rear cover 111 covers the portion of the mounting base 120 as much as possible, and therefore, the first limiting portion of the rear cover 111 and the second limiting portion on the mounting base 120 adopt the structure as described above, that is, the first limiting portion is a plurality of sets of slide ways formed by a plurality of sets of hooks distributed at intervals, and the second limiting portion is a plurality of sets of slide blocks distributed at intervals.

The remote controller for home appliances frequently removes the cover body to replace the battery, and therefore, in this application, referring to fig. 2, the purpose of removing the rear cover 110 is to replace the battery 150.

The mounting seat 120 is provided with a battery compartment 123 for placing the battery 150, the battery compartment 123 and the mounting cavity 121 are arranged on the same side of the mounting seat 120, the battery compartment 123 is sealed when the rear cover 110 is mounted in place, and the battery compartment 123 is exposed when the rear cover 11 is dismounted and mounted, so that the battery 150 can be conveniently taken out for replacement.

Referring to fig. 1, 2 to 4, the electronic device 100 further includes a front case 140, and a receiving cavity C is formed between the front case 140 and the mounting base 120, and receives electrical components of the electronic device 100, such as keys, a circuit board, and the like.

The front shell 140 is detachably mounted to the mounting base 120 (e.g., by snap-fitting or screwing), so that the front shell 140 can be easily detached for maintenance and replacement of the electric device.
