Description

Technical Field

[0001] The invention relates to a switch device with a special structure, in particular to a waterproof rocker switch. Background Art

[0002] A rocker switch, also known as a rocker switch, is a power switch commonly used in electronic devices. It is named after its shape, which resembles the shape of a boat. The structure of a rocker switch is similar to that of a toggle switch, but the handle is replaced with a rocker design. This switch has a variety of contact types, including single-pole single-throw, double-pole double-throw, and some also have indicator lights. Rocker switches are widely used in various fields, such as home appliances, office equipment, automobiles, ships, and industrial equipment.

[0003] Existing rocker switches usually have the following problems: frequent opening and closing of the rocker switch will lead to increased wear between the button and the switch housing, and the rotating shaft between the button and the switch housing will also have greater wear, which will cause the switch to loosen and switch unsmoothly over time, resulting in loose contact of the lower contact, which has an adverse effect on conductivity; and usually, there is always a certain gap between the button and the switch housing of the rocker switch, which is neither waterproof nor dustproof. After long-term use, dust will accumulate in the gap, affecting the opening and closing of the switch. In addition, the contacts on the lower side of the rocker switch will also wear after long-term use, resulting in a decrease in the contact force of the contacts, thereby affecting the conductivity. Existing rocker switches cannot compensate for the wear of the contacts. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in the present invention, unless otherwise specified, include direct and indirect connections (couplings).

[0032] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0033] like Figure 1-9As shown, the present invention provides a waterproof rocker switch 100, comprising a switch housing with an opening at the upper end and a button 101 installed in the opening of the switch housing; the button 101 is a rocker-shaped structure composed of an upper arc plate and a side panel distributed along a first direction L; the upper arc plate is covered with an elastic cover plate 1011, and a first liquid cavity 1012 is formed between the cover plate 1011 and the upper arc plate; an arc plate 1041 is respectively arranged in the opening of the switch housing and on both sides of the side panel along the first direction L, and the two arc plates 1041 are The arc-shaped openings are arranged relatively to each other; a ring-shaped sealing capsule 106 with a second liquid cavity 1061 is arranged on the outer side of the bottom end of the side panel, and the outer ring surface of the sealing capsule 106 is sealedly connected to the two arc-shaped plates 1041 and the inner surface of the switch housing, and the inner ring surface of the sealing capsule 106 is sealedly connected to the outer side surface of the bottom end of the side panel; a liquid channel 1013 is respectively opened inside the button 101 and at both ends along the first direction L, that is, each liquid channel 1013 is opened inside the upper arc plate and the side panel on the longitudinal plane including the first direction L. The two ends of each liquid channel 1013 are respectively connected to the first liquid chamber 1012 and one end of the second liquid chamber 1061 in the first direction L; lubricating oil is stored in the first liquid chamber 1012, and when one end of the cover plate 1011 in the first direction L is pressed, this end of the button 101 flips downward and the other end tilts upward, and the cover plate 1011 deforms, causing the lubricating oil in the first liquid chamber 1012 to flow into the second liquid chamber 1061 through the liquid channel 1013, so as to reduce the resistance during the pressing of the button 101.

[0034] The sealing capsule 106 is in a flat rectangular ring shape as a whole, and four long strip fixing blocks are arranged on the outer ring surface. The inner surfaces of the two arc plates 1041 and the two inner surfaces of the switch housing between the two arc plates 1041 are respectively provided with a long strip mounting groove. Figure 2 As shown. The four fixing blocks of the sealing capsule 106 are respectively snapped into the corresponding installation grooves. There are gaps between the side panels of the button 101 and the two arc-shaped plates 1041 and the switch housing, but the gaps are filled with the sealing capsule 106 and a sealed connection is achieved, thereby achieving waterproof and dustproof properties of the boat-type switch, and effectively preventing water and dust from entering the inner cavity of the switch housing where the conductive device is installed. Not only that, the button 101 of the present invention does not use a rotating shaft but is installed in the opening of the switch housing through a sealing capsule 106. The sealing capsule 106 has a certain flexibility, so the button 101 can normally achieve a certain angle of center-of-circle rotation. Therefore, compared with the prior art, the present invention not only achieves a waterproof and dustproof sealing effect, but also avoids the wear of the rotating shaft.

[0035] When the switch needs to be turned on, the cover plate 1011 on the button 101 is pressed to one side in the first direction L to deform it, and the lubricating liquid in the first liquid chamber 1012 enters the second liquid chamber 1061 through the liquid channel 1013. At the same time, the button 101 rotates around the center of the circle along the inner arc surfaces of the two arc plates 1041 by driving the sealing capsule 106 to deform. Since there is liquid in the second liquid chamber 1061, the resistance is small when the button 101 rotates, which can also reduce the wear caused by sliding friction between the button 101 and the switch housing.

[0036] like Figure 4-5 As shown, the sealing capsule 106 is flat, and has two capsule inner surfaces opposite to the inner ring surface and the outer ring surface, and the two capsule inner surfaces are respectively provided with a plurality of saw teeth 1062 in the up and down directions. Since the sealing capsule 106 is flat, the saw teeth 1062 on the two capsule inner surfaces are in contact and engaged with each other.

[0037] like Figure 2-6 As shown, an elastic sealing pad 116 is provided in the switch housing, and the sealing pad 116 divides the inner cavity of the switch housing into an upper cavity and a lower cavity which are isolated from each other. The arc plate 1041 is provided in the upper cavity, and a downwardly extending lever 1014 is provided at the bottom of the button 101. A corresponding mounting through hole is opened on the sealing pad 116, and the lever 1014 extends into the lower cavity after passing through the mounting through hole; and the outer surface of the lever 1014 is sealed and connected with the inner surface of the mounting through hole by a sealant.

[0038] The sealing pad 116 can further isolate the lower cavity where the conductive components are installed, prevent water and dust from entering therein, and protect the components inside.

[0039] The switch housing includes an upper housing 104 and a lower housing 105 that are buckled together, and a sealing pad 116 is disposed between the upper housing 104 and the lower housing 105. A support plate extending inward is disposed at the bottom of the upper housing 104 and at both ends in the first direction L, and two arc plates 1041 are disposed on the corresponding support plates.

[0040] like Figure 6As shown, the lever 1014 is a hollow structure with an opening at the bottom, and a contact rod 1015 is inserted into the lever 1014 for sliding downward; a spring is also provided in the inner cavity of the lever 1014, and one end of the contact rod 1015 is connected to the lever 1014 through the spring; a U-shaped support seat 108 is provided at the bottom of the lower cavity, and a moving contact piece 107 which can be flipped to both sides thereof is provided on the support seat 108, and the moving contact piece 107 is a symmetrical structure with a downward bending in the middle portion and upward tilting at both ends, and the middle portion is supported on the support seat 108, and a moving contact is provided at each of the two end portions; the other end of the contact rod 1015 is provided with a contact head which is adapted to a groove formed by the downward bending of the middle portion. The bottom of the support seat 108 is provided with a main terminal extending downward and passing through the switch housing, and the bottom of the lower cavity and corresponding to the position of the moving contact are respectively provided with a sub-terminal extending downward and passing through the switch housing; the contact head of the contact rod 1015 contacts the groove of the moving contact piece 107, and when the button 101 is actuated and the contact rod 1015 is tilted, the moving contact piece 107 flips to one side of the support seat 108 and the moving contact on this side contacts the corresponding sub-terminal to achieve line connection, such as Figure 7 shown.

[0041] When the key 101 rotates, the lever 1014 presses the contact rod 1015 downward and deflects it, and the contact rod 1015 presses the movable contact piece 107 downward to deform and deflect it to one side, so that the movable contact on one side contacts the static contact, and the connection between the auxiliary terminal and the main terminal is realized; when the lever 1014 presses the contact rod 1015 downward, the spring is compressed and stores elastic force, pressing the movable contact and the static contact of the switch together. When the operation is completed, the cover plate 1011 will rebound after the key 101 is released, and the lubricating liquid in the second liquid chamber 1061 flows back into the first liquid chamber 1012. Due to the existence of the saw teeth 1062 that bite each other on the inner surfaces of the two capsules, the movement between the key 101 and the arc plate 1041 will be stuck, so the key 101 will not be easily reset due to external disturbances.

[0042] The bottom end of the arc plate 1041 is elastically connected to the switch housing, and the top end of the arc plate 1041 extends upward from the opening of the switch housing; the elastic connection can be a connection through a spring hinge, which is perpendicular to the first direction L, so that the arc plate 1041 can rotate relative to its bottom position under the action of an external force, and can automatically reset after the external force disappears. A box body 1046 is respectively provided at the top of the switch housing and at both ends in the first direction L, and a wedge-shaped push block 1042 is slidably provided in each box body 1046 along the first direction L, and a push rod 1043 is provided at one end of the push block 1042 along the first direction L. A horizontal through hole is opened at a corresponding position of the inner wall of the box body 1046, and the free end of the push rod 1043 extends out of the horizontal through hole and contacts with the outer side surface of the corresponding arc plate 1041. The other end of the push block 1042 has an inclined surface, and a vertical through hole is opened at a corresponding position of the top plate of the box body 1046 above the inclined surface, and an adjusting bolt 103 is threadedly connected to the vertical through hole.

[0043] After the rocker switch 100 has been used for a period of time, the contact wear may cause the contact force to decrease. At this time, the adjusting bolt 103 can be turned downward, and the adjusting bolt 103 can push the push block 1042 in the direction of the arc plate 1041 by contacting the inclined surface of the push block 1042. Since the bottom end of the arc plate 1041 is elastically connected to the switch housing, the top rod 1043 of the push block 1042 will press against the arc plate 1041 and rotate in the direction close to the button 101, so the button 101 will move downward a certain distance in the opening of the switch housing, which increases the contact pressure between the contact rod 1015 and the moving contact piece 107, which is equivalent to giving the contact more reliable contact pressure, compensating for the contact wear, and avoiding the overall loosening of the switch.

[0044] An anti-dropout component 102 is respectively provided on the outer side walls at both ends of the switch housing in the first direction L, and a pressure airbag 1021 is provided between each anti-dropout component 102 and the outer side wall at the corresponding end of the switch housing; Figure 5 In the figure, the four outer side surfaces of the push block 1042 are in friction contact with the four inner side surfaces of the box body 1046 (the horizontal direction and perpendicular to the first direction L is set as the left and right direction in the figure), and the push rod 1043 and the horizontal through hole are always in a sealed state. The push block 1042 in each box body 1046 divides the inner cavity of the box body 1046 along the first direction L and forms a sealed air cavity 1044 on one side of the push rod 1043, and the sealed air cavity 1044 is connected to the corresponding top pressure airbag 1021 through an air channel 1045 opened in the bottom plate of the box body 1046 and the outer side wall at the corresponding end of the switch housing.

[0045] When the adjusting bolt 103 is rotated downward to make the push block 1042 slide, the gas in the sealed air cavity 1044 will enter the interior of the top pressure airbag 1021 through the airway 1045, causing the top pressure airbag 1021 to expand, thereby causing the anti-detachment component 102 to expand outward, thereby increasing the reliability of the installation of the rocker switch 100.

[0046] In another preferred embodiment of the rocker switch 100 of the present invention, two levers 1014 are symmetrically arranged at the bottom of the button 101 with respect to the first direction L, and two mounting through holes are correspondingly provided on the sealing pad 116 for the two levers 1014 to pass through respectively; a contact rod 1015 is inserted and slid downward in each lever 1014, two support seats 108 are correspondingly arranged at the bottom of the lower cavity, and each support seat 108 is provided with a moving contact piece 107, and each support seat 108 is provided with a main terminal at the bottom, which are a first main terminal 109 and a second main terminal 110 respectively; Figure 8 As shown, a sub-terminal is provided at the bottom of the lower cavity and corresponding to the positions of the moving contacts of the two moving contact pieces 107, which are the first sub-terminal 111, the second sub-terminal 112, the third sub-terminal 113 and the fourth sub-terminal 114; the above four sub-terminals are distributed in a rectangular shape, and the two sub-terminals located on the diagonal of the rectangle are connected by an insulating support plate 115.

[0047] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
