[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] like Figures 1 to 7 As shown, this embodiment provides a battery disassembly and assembly structure, including a battery 900, a structural body 100, a sliding member 200 and an elastic member 300; the structural body 100 is provided with a receiving groove 103 and an avoidance groove 102, the battery 900 can be detachably installed in the receiving groove 103, and the avoidance groove 102 is recessed at the groove bottom of the receiving groove 103; the sliding member 200 can move between a first position and a second position along a working direction, when the sliding member 200 is in the first position, the sliding member 200 is penetrated in the avoidance groove 102, and when the sliding member 200 is in the second position, the sliding member 200 at least partially passes through the receiving groove 103; the elastic member 300 elastically connects the structural body 100 and the sliding member 200, and the elastic member 300 is used to drive the sliding member 200 to move to the first position.

[0040] The battery disassembly and assembly structure can control the sliding member 200 to enter and exit the receiving groove 103 by driving the sliding member 200 to move between the first position and the second position, thereby utilizing the thrust applied to the battery 900 when the sliding member 200 enters the receiving groove 103 to push the battery 900 out of the receiving groove 103, thereby achieving the purpose of quickly disassembling the battery 900 in the receiving groove 103; and the design of the elastic member 300 driving the sliding member 200 to move to the first position realizes the timely reset of the sliding member 200, avoids the situation where the sliding member 200 accidentally enters the receiving groove 103, and improves the user experience. The above design realizes the structural simplification of the battery disassembly and assembly structure, reduces the workload of the user, and reduces the difficulty of disassembling and assembling the battery 900.

[0041] In this embodiment, the battery disassembly and assembly structure is a deep arc-shaped battery compartment. In other implementations of this embodiment, the battery disassembly and assembly structure is a battery accommodating device of other shapes. The specific structure of the battery accommodating device is a conventional setting in this field, which is determined by the staff in this field according to the actual engineering practice and will not be elaborated here.

[0042] In this embodiment, the side wall of the avoidance groove 102 is provided with two oppositely arranged first through holes, and the side wall of the accommodating groove 103 is provided with two oppositely arranged second through holes; the first through hole is connected to the second through hole adjacent to it to form an elongated hole 101, and the length direction of the elongated hole 101 is parallel to the working direction, and the sliding member 200 passes through the two elongated holes 101 at the same time.

[0043] By limiting the shape of the elongated hole 101, the moving trajectory of the sliding member 200 is planned, reducing the risk of accidental position displacement of the sliding member 200, ensuring smooth removal of the battery 900, and guaranteeing the long-term stable operation of the battery disassembly and assembly structure.

[0044] Furthermore, the sliding member 200 includes a sliding plate 220 and a sliding cap 210 fixed to one end of the sliding plate 220, the sliding plate 220 is inserted into the elongated hole 101, and the sliding cap 210 at least partially extends out of the structural body 100. Specifically, the sliding cap 210 is fixed to the top surface of the sliding plate 220, and a section of the sliding cap 210 away from the sliding plate 220 is provided with an anti-slip layer 211.

[0045] By pushing the sliding cap 210, the sliding member 200 can slide along the working direction, thereby pushing the battery 900 in the receiving groove 103, so that the battery 900 is separated from the receiving groove 103, and the battery 900 is conveniently removed from the battery disassembly structure. After the user releases the hand, the sliding member 200 is reset under the drive of the elastic member 300. The setting of the sliding cap 210 reduces the difficulty of interaction between the user and the sliding member 200, improves the user's experience, and simplifies the specific structure of the sliding member 200.

[0046] Specifically, the two sides of the accommodating groove 103 are connected to a transition cavity, the sliding plate 220 is arranged in a U shape and the two ends are bent upward, and the sliding member 200 contacts the battery 900 through the middle part of the sliding plate 220; when the sliding member 200 moves between the first position and the second position, the middle part of the sliding plate 220 moves between the accommodating groove 103 and the avoidance groove 102, and the two end parts of the sliding plate 220 are always in the corresponding transition cavity. The above design realizes the structural optimization of the sliding member 200, further reduces the space occupied by the sliding member 200, optimizes the structural layout of the battery disassembly and assembly structure, and reduces the production cost.

[0047] Furthermore, the structural body 100 forms a main body cavity, which is connected to the accommodating groove 103 and the avoidance groove 102 through the elongated hole 101. The structural body 100 is provided with a limiting through hole 112, and the main body cavity is connected to the external environment through the limiting through hole 112; both ends of the sliding plate 220 extend into the main body cavity, and the sliding cap 210 passes through the limiting through hole 112.

[0048] By means of the main body cavity, the relative position between the structural main body 100 and the sliding member 200 is limited, reducing the risk of the sliding member 200 accidentally shifting from the structural main body 100. At the same time, the main body cavity can also protect the sliding member 200 and the elastic member 300, reducing the risk of damage to the battery disassembly structure and improving the appearance.

[0049] In this embodiment, a recessed groove 221 is recessed in the middle of the sliding plate 220, and the groove wall of the recessed groove 221 can match and fit with the surface of the battery 900. The design of matching and fitting the recessed groove 221 with the surface of the battery 900 optimizes the force of the battery 900, improves the condition when the battery 900 is separated from the receiving groove 103, reduces the probability of the battery 900 quickly popping out of the receiving groove 103, helps to improve the success rate of the battery 900 removal operation, and improves the user experience.

[0050] Exemplarily, the hole wall of the elongated hole 101 is provided with a sliding track 121, the sliding track 121 extends along the working direction, and the sliding member 200 is slidably matched with the sliding track 121. The sliding match between the sliding member 200 and the sliding track 121 ensures that the sliding member 200 can move smoothly between the first position and the second position along the working direction, thereby reducing the risk of the sliding plate 220 being accidentally displaced, and ensuring the long-term stable operation of the sliding member 200.

[0051] Specifically, the sliding track 121 has a ramp slide and two convex rails arranged on both sides of the ramp slide, and the bottom surface of the sliding plate 220 is provided with four grooves, and the grooves and the convex rails are slidably matched one by one. The arrangement of the ramp slide and the convex rails helps to improve the matching condition between the sliding track 121 and the sliding plate 220, and further reduces the risk of the sliding plate 220 detaching from the sliding track 121.

[0052] In this embodiment, the structural body 100 includes an upper body plate 110 and a lower body plate 120. The lower body plate 120 is fixedly installed on the upper body plate 110. The upper body plate 110 is penetrated by an upper body through hole 111. The edge of the upper body through hole 111 is bent with a bent plate 113. The lower body plate 120 is recessed with an installation groove 123. The groove wall of the installation groove 123 and the bent plate 113 form a receiving groove 103 and an avoidance groove 102.

[0053] The split design of the upper main plate 110 and the lower main plate 120 reduces the manufacturing difficulty of the structural main body 100, reduces the production cost of the structural main body 100, and helps to improve the production efficiency of the structural main body 100. The design of the groove wall of the installation groove 123 and the bending plate 113 enclosing the accommodating groove 103 and the avoiding groove 102 reduces the molding difficulty of the accommodating groove 103, the avoiding groove 102 and the long hole 101, reduces the processing cost of the accommodating groove 103, the avoiding groove 102 and the long hole 101, and further improves the manufacturing efficiency of the structural main body 100.

[0054] Exemplarily, the working direction is set at an angle to the depth direction of the accommodating groove 103. The above design defines the layout of the elongated hole 101 on the groove wall of the accommodating groove 103 and the avoidance groove 102, thereby optimizing the matching mode between the structural body 100 and the sliding member 200, reducing the space occupied by the battery disassembly and assembly structure, and also reducing the difficulty of the user to apply force to the sliding cap 210, which helps to improve the user experience.

[0055] In this embodiment, the elastic member 300 is a tension spring, a first connecting hook 122 is fixedly provided on the structural body 100, a second connecting hook 212 is fixedly provided on the sliding member 200, and both ends of the tension spring are respectively hooked and connected with the first connecting hook 122 and the second connecting hook 212. The design that both ends of the tension spring are respectively hooked with the first connecting hook 122 and the second connecting hook 212 is simple and reliable, ensuring that the elastic member 300 can smoothly complete the driving action of the sliding member 200, so as to achieve the timely reset of the sliding member 200, thereby simplifying the user's operation and further improving the user experience.

[0056] The present embodiment also provides a head-mounted display device, including a negative electrode spring piece 400, a positive electrode spring piece 500, a PCBA (Printed Circuit Board Assembly) 600 and the above-mentioned battery disassembly and assembly structure, the negative electrode spring piece 400 and the positive electrode spring piece 500 are both fixedly installed in the accommodating groove 103, the PCBA 600 is installed in the structural body 100, and the battery 900 can be electrically connected to the PCBA 600 through the negative electrode spring piece 400 and the positive electrode spring piece 500.

[0057] The head mounted display device is connected to the battery 900 in the receiving groove 103 through the negative spring sheet 400 and the positive spring sheet 500 to achieve the purpose of powering the PCBA 600. With the arrangement of the above battery disassembly and assembly structure, the head mounted display device can be powered off immediately after the battery 900 is pushed out, thereby optimizing the operation mode of the head mounted display device, simplifying the specific structure, and reducing the occupied space.

[0058] Specifically, the negative electrode spring sheet 400 and the positive electrode spring sheet 500 are special-shaped spring sheets of the same shape. The negative electrode spring sheet 400 is fixed to the lower main body plate 120 by two screws; the positive electrode spring sheet 500 is welded to the protective small plate, and the protective small plate is fixed to the lower main body plate 120 by four screws; the upper main body plate 110 is fixed to the lower main body plate 120 by eleven buckles and eight screws.
