Description
Technical Field
[0001] This utility model relates to the field of automotive switch technology, and in particular to a rocker-type reversing switch. Background Technology
[0002] In the field of automotive built-in switch technology, this technology is mainly applied to built-in switches for automotive electrical switches such as car seat switches, car window lift switches, and car sunroof switches. The circuit contact method is a single-pole double-throw circuit with two loops. Its main function is to control the forward and reverse rotation of the car motor through the on / off switching of the reversing switch to achieve the car's electrical performance (such as seat height and fore-and-aft adjustment).
[0003] In existing rocker-type reversing switches capable of forward and reverse rotation, the rocker is placed in the cavity of the pressing member. The rocker rotates back and forth to press the corresponding side of the pressing member, thereby driving the pressing member to move in the same direction. After the pressing member moves into place, the moving contact on the same side can achieve the purpose of circuit switching. The rocker-type reversing switch with the above structure is not reasonable enough and needs to be improved. Utility Model Content
[0004] To solve the above problems, this utility model provides the following technical solution: A rocker-type reversing switch includes a switch base, a set of stationary contact components and swing contacts, a common contact, and a rocker arm. The switch base has a cavity. The stationary contact components are arranged in two sets, each including a first stationary contact and a second stationary contact. The upper ends of both the first and second stationary contacts are located within the cavity. The upper end of each first stationary contact is also provided with a connecting structure for mounting the corresponding swing contact. The swing end of the swing contact is arranged to swing up and down. The common contact has two contact ends, which are arranged on both sides of the swing trajectory of the swing end of the swing contact. The rocker arm is rotatably connected to the switch base and is positioned above the swing contacts. Two actuating elements are also connected below the rocker arm. The actuating elements are arranged back and forth and located within the cavity. The actuating elements are also connected to the corresponding swing contacts.
[0005] The advantages of the above technical solution are as follows: By using the swing end of the swinging contact to swing up and down within the cavity, and by using two actuating elements arranged in a front-to-back configuration below the rocker arm, the rocker arm rotates forward or backward. The rocker arm presses against the actuating element on the corresponding side, causing the actuating element to move downward. This causes the swing end of the swinging contact on that side to swing downward. Once the swing is complete, the swing end of the swinging contact on that side switches its connection with the corresponding second stationary contact and the common contact. When the actuating element stops pressing, the swing end of the swinging contact swings upward and resets the actuating element. The swing end of the swinging contact on that side then switches its connection with the corresponding second stationary contact and the common contact again. The circuit switching action is completed. Therefore, without changing the direction of the rocker arm, the installation state of the swinging contact and the swing direction of the swing end are changed. Moreover, only two contact ends need to be set on the common contact to achieve cooperation with the two second stationary contacts. The installation is also relatively convenient, and the overall structural design is reasonable.
[0006] Furthermore, a sliding opening is provided through the upper surface of the switch base, and the actuating element is fitted into the corresponding sliding opening. A retaining edge is also provided on the upper surface of the switch base, and the rocker arm is connected to the inside of the retaining edge, and the sliding opening is located inside the retaining edge.
[0007] The advantages of the above technical solution are: the sliding port ensures stable up-and-down sliding of the actuating element; the baffle not only enables effective installation of the rocker arm but also greatly reduces the molding cost of the switch base; and the baffle not only prevents dust intrusion to a certain extent, giving the reversing switch a certain dustproof function, and the structural design is reasonable.
[0008] Furthermore, a connecting block is provided on the lower surface of the rocker arm, and a limiting groove is also provided on the lower surface of the connecting block, with the upper end of the actuating element fitting into the limiting groove.
[0009] The advantages of adopting the above technical solution are: by setting a connecting block with a limiting groove, the joystick can drive the action of the trigger more stably, and the shape of the joystick is also reasonable.
[0010] Furthermore, rotating posts are provided on both the left and right sides of the connecting block, and rotating holes are provided on both the left and right sides of the retaining edge, with the rotating holes cooperating with the rotating posts.
[0011] The advantages of the above technical solution are: the combination of the rotating column and the rotating hole allows the rocker arm to rotate back and forth, and the combination structure is simple and reasonable.
[0012] Furthermore, the lower part of the end face of the rotating column is provided with a first guide slope, the upper surface of the stop is provided with a second guide slope, and the rotating hole is provided directly below the corresponding second guide slope, the second guide slope and the first guide slope cooperate with each other.
[0013] The advantages of adopting the above technical solution are: by setting the first and second inlet inclined surfaces, the rotating column can be quickly inserted into the rotating hole, the fitting process is smooth and labor-saving, and the production efficiency is improved.
[0014] Furthermore, the switch base is assembled from an upper base and a lower base. The rocker arm and the actuating element are both located on the upper base, and the cavity is located on the lower surface of the upper base. The first stationary contact, the second stationary contact, and the common contact are all located on the lower base.
[0015] The advantages of the above technical solution are as follows: the switch base is constructed by assembling an upper base and a lower base, and the cavity is located on the lower surface of the upper base, which facilitates the assembly of the reversing switch by the assembly personnel and effectively improves the installation efficiency. Moreover, by adopting the above method, the lower base with the first stationary contact, the second stationary contact and the common contact can use the existing mature switch base of the transverse reversing switch, without the need to re-mold and manufacture the entire switch base, which greatly saves production costs and mold costs.
[0016] Furthermore, the reversing switch also includes a core post, the upper end of the rocker arm is provided with an open receiving cavity, the core post cooperates with the receiving cavity and one end protrudes out of the receiving cavity, the receiving cavity is also provided with an elastic element, and the lower end of the core post is supported on the elastic element.
[0017] The advantages of adopting the above technical solution are: when the terminal drives the rocker arm to move, the core column will move up and down elastically within the receiving cavity under the action of the elastic element, thereby making the linkage between the rocker arm and the terminal more stable and the structural design more reasonable.
[0018] Furthermore, the peripheral wall of the core post is provided with a locking block and a guide block, and the inner wall of the receiving cavity is provided with a locking opening, a first groove, and a second groove. The locking opening cooperates with the locking block, and the length of the locking opening is greater than the length of the locking block. The first groove cooperates with the guide block, and the second groove is positioned directly above the locking opening. The upper ends of both the first groove and the second groove are through-hole.
[0019] The advantages of the above technical solution are as follows: the combination of the locking block and the locking port effectively avoids the instability of the core column installation and makes it less likely to fall off; the combination of the guide block and the first groove makes it less likely for the core column to rotate circumferentially, making the installation more reasonable; and the second groove allows the locking block to be smoothly inserted into the locking port.
[0020] Furthermore, the bottom surface of the switch base is also provided with a positioning structure and a support structure.
[0021] The advantages of the above technical solution are: the positioning structure allows the reversing switch to be accurately and stably installed on the external carrier; the support structure ensures that there is a gap between the bottom of the reversing switch base and the carrier surface after installation, which facilitates subsequent soldering.

Detailed Implementation
[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model and / or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort. Furthermore, references to orientation only indicate the relative positional relationship between the components, not their absolute positional relationship.
[0025] Please see Figures 1 to 11 As shown, a rocker-type reversing switch includes a switch base 1, a group of stationary contact components and swing contacts 2, a common contact 3, and a rocker 4. The switch base 1 has a cavity 5. There are two groups of stationary contact components and two swing contacts 2, with the two groups of stationary contact components arranged front and back. The stationary contact components include a first stationary contact 6 and a second stationary contact 7. The upper ends of both the first stationary contact 6 and the second stationary contact 7 are located within the cavity 5. The upper end of each first stationary contact 6 is also provided with a connecting structure for mounting the corresponding swing contact 2. The swing end of the swing contact 2 is arranged to swing up and down. The common contact 3 has two contact ends 8. The contact ends 8 and the corresponding second stationary contact 7 are arranged on both sides of the swing trajectory of the swing end of the swing contact 2. The rocker arm 4 is connected to the switch base 1 and rotates back and forth. The rocker arm 4 is arranged above the swing contact 2, and two actuating elements 9 are also connected below the rocker arm 4. The actuating elements 9 are arranged back and forth and located in the cavity 4. The actuating elements 9 are also connected to the corresponding swing contact 2. The lower end of the actuating element 9 interacts with the swing contact 2, and the upper end of the actuating element 9 interacts with the rocker arm 4. Contact points are provided on the swing end of the swing contact 2 and the two contact ends 8 of the common contact 3.
[0026] In the above structure, the swinging end of the swinging contact 2 swings up and down within the cavity 4. Two actuating elements 9 are positioned below the rocker arm 4 in a front-to-back configuration. The rocker arm 4 rotates forward or backward, pressing against the actuating element 9 on the corresponding side. This pressing causes the actuating element 9 to move downwards, causing the swinging end of the swinging contact 2 on that side to swing downwards. Once the swinging end is in position, the swinging end of the swinging contact on that side switches its connection with the corresponding second stationary contact 7 and common contact 3. After the actuating element 9 stops pressing, the swinging end of the swinging contact 2 will... Swinging upwards and resetting the actuating element 9, the swinging end of the swinging contact 2 on this side will again switch its connection with the corresponding second stationary contact 7 and common contact 3. The circuit switching action is completed. It should be noted that the second stationary contact 7 and common contact 3 are arranged on the upper and lower sides. Therefore, without changing the direction of the rocker arm 4, the installation state of the swinging contact 2 and the swinging direction of the swinging end are changed. Moreover, only two contact ends 8 need to be set on the common contact 3 to achieve cooperation with the two second stationary contacts 7. The installation is also relatively convenient, and the overall structural design is reasonable.
[0027] In this embodiment, a sliding opening 10 is provided through the upper surface of the switch base 1, and the actuating element 9 is fitted into the corresponding sliding opening 10. A retaining edge 11 is also provided on the upper surface of the switch base 1. The rocker arm 4 is connected to the inside of the retaining edge 11, and the sliding opening 10 is also provided to the inside of the retaining edge 11. In the above structure, the setting of the sliding opening 10 realizes the stability of the up and down sliding of the actuating element 9. The setting of the retaining edge 11 not only realizes the effective installation of the rocker arm 4, but also greatly reduces the molding cost of the switch base 1. In addition, the setting of the retaining edge 11 can also prevent dust from entering to a certain extent, so that the reversing switch has a certain dustproof function. The structural design is reasonable.
[0028] In this embodiment, a connecting block 12 is provided on the lower surface of the rocker arm 4, and a limiting groove 13 is also provided on the lower surface of the connecting block 12. The upper end of the actuating member 9 is fitted into the limiting groove 13. The limiting groove 13 extends back and forth. In the above structure, by providing a connecting block 12 with a limiting groove 13, it is ensured that the rocker arm 4 can drive the actuating member 9 to move more stably. At the same time, the setting of the connecting block 12 allows the structure of the rocker arm 4 above the connecting block 12 to be cylindrical. Therefore, the forming of the rocker arm 4 is also reasonable. More specifically, the stop 11 is also set in a rectangular frame shape, and the connecting block 12 is also set in a rectangular block shape. The left and right sides of the connecting block 12 and the left and right sides of the stop 11 are fitted with a gap. A hollow cavity can also be set on the rocker arm 4. The hollow cavity can be partially located on the connecting block 12, thereby further reducing production costs.
[0029] In this embodiment, rotating posts 14 are provided on both the left and right sides of the connecting block 12, and rotating holes 15 are provided on both the left and right sides of the stop 11. The rotating holes 15 cooperate with the rotating posts 14. In the above structure, the rocker arm 4 can rotate back and forth through the cooperation of the rotating posts 14 and the rotating holes 15. The cooperation structure is simple and reasonable.
[0030] In this embodiment, a first guide slope 16 is provided on the lower part of the end face of the rotating column 14, and a second guide slope 17 is provided on the upper surface of the retaining edge 11. The rotating hole 15 is positioned directly below the corresponding second guide slope 17. The second guide slope 17 cooperates with the first guide slope 16. In the above structure, by setting the first guide slope 16 and the second guide slope 17, the rotating column 14 can be quickly inserted into the rotating hole 15. The cooperation process is smooth and labor-saving, which improves production efficiency.
[0031] In this embodiment, the switch base 1 is assembled from an upper base 18 and a lower base 19. The rocker arm 4 and the actuating element 9 are both located on the upper base 18. That is, the stop 11 and the sliding opening 10 are located on the upper base 18, and the cavity 4 is located on the lower surface of the upper base 18. The first stationary contact 6, the second stationary contact 7, and the common contact 3 are all located on the lower base 19. In the above structure, the switch base 1 is assembled from the upper base 18 and the lower base 19, and the cavity 4 is located on the lower surface of the upper base 19. This facilitates the assembly of the reversing switch by the assembly personnel and effectively improves safety. In terms of efficiency, and by adopting the above method, the lower base with the first stationary contact 6, the second stationary contact 7 and the common contact 8 can adopt the existing mature switch base of the transverse reversing switch. That is to say, the lower base components in the toggle reversing switch and the transverse reversing switch achieve the purpose of sharing. Therefore, there is no need to re-mold and manufacture the entire switch base 1, which greatly saves production costs and mold costs. It should be noted that the first stationary contact 6 and the common contact 3 are integrally injection molded on the lower base 19, and the second stationary contact 7 is inserted into the lower base 19 through the corresponding mounting port.
[0032] In this embodiment, the reversing switch also includes a core post 20. The upper end of the rocker arm 4 is provided with an open receiving cavity 21. The core post 20 cooperates with the receiving cavity 21 and one end protrudes out of the receiving cavity 21. An elastic element 22 is also provided inside the receiving cavity 21. The lower end of the core post 20 is supported on the elastic element 22. In the above structure, when the terminal drives the rocker arm 4 to move, the core post 20 will move up and down elastically inside the receiving cavity 21 under the action of the elastic element 22, thereby making the linkage between the rocker arm 4 and the terminal more stable and the structural design more reasonable.
[0033] In this embodiment, the peripheral wall of the core post 20 is provided with a locking block 23 and a guide block 24. The inner wall of the receiving cavity 23 is provided with a locking opening 25, a first groove 26, and a second groove 27. The locking opening 25 cooperates with the locking block 23, and the length of the locking opening 25 is greater than the length of the locking block 23. That is to say, the locking block 23 can move up and down within the locking opening 25. The first groove 26 cooperates with the guide block 24. The second groove 27 is positioned directly above the locking opening 25. The upper ends of both the first groove 26 and the second groove 27 are through-holes in the above structure. Through the cooperation of the locking block 23 and the locking opening 25, the stability of the core post 20 installation is effectively avoided, and it is not easy for it to fall off. Through the cooperation of the guide block 24 and the first groove 26, the core post 20 is not easy to rotate circumferentially, making the installation more reasonable. Furthermore, by providing the second groove 27, the locking block 23 can be smoothly inserted into the locking opening 25.
[0034] In this embodiment, a positioning structure 28 and a support structure 29 are also provided on the bottom surface of the switch base 1. More specifically, the positioning structure 28 and the support structure 29 are provided on the bottom of the lower base 19. The positioning structure 26 can be multiple positioning posts, and the support structure 27 can be multiple support feet. In the above structure, the positioning structure 28 enables the reversing switch to be accurately and stably installed on the external carrier. The support structure 29 ensures that after the reversing switch is installed, there will be a gap between the bottom of its base and the surface of the carrier, which facilitates subsequent soldering.
[0035] In this embodiment, the connecting structure on the first stationary contact 6 includes a first mounting arm 30 and a second mounting arm 31, both of which are convex. The swing contact 2 is provided with a first hollow portion 32 and a second hollow portion 33. A spring piece 34 is provided in the first hollow portion 31, and two first positioning protrusions 35 are provided on the suspended end of the spring piece 34. The first positioning protrusions 35 are engaged with the shoulder of the first mounting arm 30, so that the spring piece 34 is stably abutted against the upper part of the first mounting arm 30. Two second positioning protrusions 36 are provided in the second hollow portion 33, and the second positioning protrusions 36 are engaged with the shoulder of the first mounting arm 31. Through the arrangement of the first positioning protrusions 35 and the second positioning protrusions 36, the swing contact 2 is stably connected to the first stationary contact 6.
[0036] In this embodiment, the upper seat 18 forms a mounting plate 37 at the bottom of the peripheral side wall of the cavity 4. The mounting plate 37 is provided with a mounting slot 38. A mounting groove is formed on the side wall of the lower seat 19. The mounting plate 37 fits into the mounting groove, and a mounting block 39 is provided in the mounting groove. The mounting block 39 cooperates with the mounting slot 38. The upper seat 18 and the lower seat 19 are assembled by engaging the mounting slot 38 on the mounting plate 37 with the mounting block 39 in the mounting groove.
