Description

Technical Field

[0001] The utility model relates to the field of electronic devices, and particularly relates to a battery compartment anti-leakage structure and a remote controller. Background Art

[0002] The battery of a remote controller is usually placed in the battery compartment of the housing, and the electrical connection with the PCB board inside the housing is realized through the conductive spring in the battery compartment. Among them, the conductive spring is installed in the preset installation hole of the battery compartment, and the lead wire connecting the conductive spring and the PCB board needs to pass through the installation hole. However, this design has significant defects: as the battery usage time increases, battery aging may cause leakage. Once the battery leaks, these corrosive liquids are very likely to penetrate into the PCB board area through the installation hole and the lead wire relief hole, resulting in corrosion of the PCB board, and further affecting the overall function and service life of the remote controller.

[0003] To address the above problems, the industry has tried to reduce the risk of leakage directly contacting the PCB board by reducing the size of the installation hole. Although this measure has slowed down the occurrence of the problem of PCB board corrosion to a certain extent, due to the accumulation and uncontrollability of battery leakage, it is still difficult to completely avoid the situation where a small amount of leakage penetrates into the PCB board and causes corrosion, thus failing to fundamentally solve the problem.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0033] When the battery ages, battery leakage may flow onto the PCB through the mounting holes and relief holes, corroding the PCB and affecting the normal use of the remote control. Currently, the size of the mounting holes and relief holes is mainly reduced to reduce the risk of battery leakage contacting the PCB, but there is still a problem of a small amount of battery leakage corroding the PCB.

[0034] To solve the above technical problems, this embodiment provides a battery compartment anti-leakage structure and a remote control. Please refer to Figures 1 to 5 as shown in Figure 1 which is the front exploded view of the remote control in the embodiment, Figure 2 which is the back exploded view of the remote control in the embodiment, Figure 3 which is the back view of the remote control in the embodiment, Figure 4 which is Figure 3 the cross-sectional view of the C-section in Figure 5 and which is the three-dimensional view of the housing and the conductive spring in the embodiment.

[0035] The remote control of this embodiment, as shown in Figure 1 and Figure 2 includes a battery compartment anti-leakage structure 1, a housing 2, a PCB 3, and a conductive spring 4.

[0036] As shown in Figure 1 and Figure 2 the above-mentioned battery compartment 21 is provided on the housing 2. The housing 2 is provided with an inner cavity for accommodating the PCB 3 and a mounting hole 20 communicating the battery compartment 21 and the inner cavity. The mounting hole 20 is used for mounting the conductive spring 4. Among them, the PCB 3 can be fixed in the housing 2 by existing connection methods such as screws and snaps.

[0037] As shown in Figure 1 and Figure 4 the conductive spring 4 is located in the battery compartment 21 and is connected to the PCB 3 through a lead 40 for supplying the power of the battery to the PCB 3. The above-mentioned lead 40 passes through the mounting hole 20. It can be understood that the conductive spring 4 can be arranged in the mounting hole 20 by existing methods such as clamping and bonding.

[0038] As shown in Figure 1 and Figure 4 the battery compartment anti-leakage structure 1 includes: a seal 10 fixedly provided on the inner side of the housing 2. The seal 10 closely adheres to the periphery of the mounting hole 20 to seal the mounting hole 20. The seal 10 seals and wraps the outer surface of the lead 40. Among them, the periphery of the mounting hole 20 includes the inner side, the outer side, or the inner side and the outer side of the mounting hole 20, that is, the mounting hole 20 can be sealed by the seal 10.

[0039] In the remote control and battery compartment anti-leakage structure 1 of the above technical solution, the mounting hole 20 of the conductive spring 4 is sealed by the seal 10 to prevent battery leakage from entering the inner cavity through the mounting hole 20 and corroding the PCB board 3. At the same time, the seal 10 seals and wraps the outer surface of the lead 40 to prevent battery leakage from entering the inner cavity between the lead 40 and the seal 10 and corroding the PCB board 3. It can be seen that compared with the anti-leakage method of reducing the size of the mounting hole 20 in the prior art, the remote control and battery compartment anti-leakage structure 1 prevents battery leakage from entering the inner cavity of the housing 2 through the mounting hole 20 through the seal 10, thereby preventing the battery leakage from corroding the PCB board 3, which can effectively improve the reliability of the product and extend the service life.

[0040] In an embodiment where the above-mentioned seal 10 seals the mounting hole 20 and seals and wraps the outer surface of the lead 40, refer to Figure 1 and Figure 4 As shown, the seal 10 includes a sealing plate 11 and an insertion strip 12 that are integrally connected. The sealing plate 11 is fixedly arranged on the inner side of the housing 2 and closely adheres to the periphery of the mounting hole 20 on the back of the battery compartment 21. The insertion strip 12 extends into the mounting hole 20 and closely adheres to the inner side of the mounting hole 20, so that the insertion strip 12 and the sealing plate 11 jointly seal the mounting hole 20; the lead 40 passes through the insertion strip 12, and the outer surface of the lead 40 closely adheres to the insertion strip 12. In this embodiment, the seal 10 jointly seals the mounting hole 20 through the sealing plate 11 and the insertion strip 12. The design of the insertion strip 12 extending into the mounting hole 20 facilitates leading out the lead 40 of the conductive spring 4 located in the mounting hole 20.

[0041] Exemplarily, refer to Figure 5 As shown, the mounting hole 20 is composed of a first region 201 and a second region 202. The first region 201 penetrates the battery compartment 21 in the depth direction of the battery compartment 21, which can make way for the conductive spring 4 to be inserted into the battery compartment 21. The second region 202 penetrates the battery compartment 21 in the width direction of the battery compartment 21 and is used to provide space for leading out the lead 40; refer to Figure 2 and Figure 4 As shown, the sealing plate 11 closely adheres to the periphery of the first region 201 to seal the first region 201; the insertion strip 12 is inserted into the second region 202 and closely adheres to the inner side of the second region 202 to seal the second region 202; the lead 40 enters the inner cavity through the second region 202.

[0042] It can be understood that the mounting hole 20 can also be a relief hole that only makes way for the conductive spring 4, and the lead is also led out from the relief hole.

[0043] Exemplarily, refer to Figure 1 and Figure 4As shown, the lead wire 40 passes through the inserting strip 12, and the outer surface of the lead wire 40 is closely fitted with the inserting strip 12 in the following manner: the inserting strip 12 includes a connecting section 101 and a bending section 102 that are integrally connected, the connecting section 101 is integrally connected with the sealing plate 11, the bending section 102 and the connecting section 101 are folded around the connection and relatively fixed, and the outer surface of the lead wire 40 is closely fitted between the bending section 102 and the connecting section 101.

[0044] Exemplarily, the above-mentioned integral connection is any one of integral molding, bonding, and welding. Figure 1 As shown, the connecting section 101 and the bending section 102 are integrally formed of elastic materials such as silicone, and a fold is provided at the connecting portion. Figure 1 The seal 10 in the dotted line state has a connecting section 101 and a bending section 102 in a plate shape. When installing, the bending section 102 is folded in half around the fold. Figure 1 The several bending sections 102 in the dotted line state are shown and are fixedly attached to the connecting section 101. Figure 1 The seal 10 is shown in the solid line state.

[0045] In one embodiment of the above-mentioned bending section 102 and connecting section 101 being relatively fixed, refer to Figure 1 As shown, a slot 103 is provided on the sealing plate 11, and one end of the bending section 102 away from the connecting section 101 is arranged in the slot 103, so that the bending section 102 and the connecting section 101 are relatively fixed. This embodiment has the advantage of convenient installation.

[0046] In other embodiments in which the bending section 102 and the connecting section 101 are relatively fixed, the bending section 102 and the connecting section 101 are fixedly connected by bonding, ultrasonic welding, or the like.

[0047] In order to make the lead wire 40 fit more closely between the bending section 102 and the connecting section 101, refer to Figure 1 As shown, the connecting section 101 and the bending section 102 are respectively provided with a fitting groove 104 adapted to the lead 40, and the outer surface of the lead 40 is tightly fitted between the inner sides of the fitting groove 104 of the connecting section 101 and the bending section 102. It can be understood that the shape of the fitting groove 104 is adapted to the lead 40, such as when the cross section of the lead 40 is circular, the fitting groove 104 is an arc groove.

[0048] The sealing member 10 is made of silicone or rubber and has a certain elasticity. It can deform elastically to a certain extent after being subjected to force so as to fit tightly around the mounting hole 20 and the periphery of the lead 40 .

[0049] In one embodiment, the sealing member 10 is fixedly arranged on the inner side of the housing 2. Figure 2As shown, the PCB board 3 is provided with at least two positioning holes 30, and the seal 10 is provided with positioning posts 13 adapted to the positioning holes 30. The positioning posts 13 cooperate with the positioning holes 30 to relatively fix the PCB board 3 and the seal 10 in the plane direction of the PCB board 3. The seal 10 is tightly pressed between the PCB board 3 and the housing 2 in the thickness direction of the PCB board 3, so that the seal 10 is completely fixed inside the housing 2.

[0050] Since the conductive spring 4 is pre-connected to the PCB board 3 through the lead 40 to form an integral structure. Exemplarily, refer to Figure 1 As shown, the seal 10 can be installed in the following way: the seal 10 is pushed between the PCB board 3 and the lead 40 along the Figure 1 arrow direction to align the positioning holes 30 and the positioning posts 13; then the lead 40 is hermetically wrapped by the seal 10, such as hermetically sealing the outer surface of the lead 40 through the above-mentioned connecting section 101 and the bending section 102; finally, the circuit board is fixed in the housing 2. In this process, the conductive spring 4 extends into the battery compartment 21, and the seal 10 closely fits around the mounting hole 20, such as being tightly pressed between the PCB board 3 and the housing 2, to achieve the sealing of the mounting hole 20.

[0051] In other embodiments where the above-mentioned seal 10 is fixedly provided inside the housing 2, the seal 10 is fixed on the back of the battery compartment 21 or the PCB board 3 by means of bonding or the like.

[0052] In one embodiment of the above-mentioned housing 2, the housing 2 includes an upper housing and a lower housing that are detachably and fixedly connected by screws or snaps, and an inner cavity is formed between the upper and lower housings.

[0053] In order to further improve the stability of the seal connection structure, refer to Figure 2 As shown, the seal 10 and the back of the battery compartment 21 are respectively provided with mutually cooperating positioning grooves 105 and positioning protrusions 203.

[0054] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
