Description

Technical Field

[0001] This utility model relates to the field of reversing switch technology, and in particular to a dustproof reversing switch for use in automobiles. 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] Existing reversing switches capable of forward and reverse rotation include a base assembly and an upper assembly. The upper assembly includes an upper seat, two contacts, and a switch base. By sliding the switch base, the corresponding contacts are pressed or released, thereby changing the contact mode of the contacts on the base assembly. However, this type of reversing switch does not limit the travel of the switch base, making its use unsafe. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dustproof reversing switch for automobiles. The switch has a reasonable structure and effectively limits the stroke of the switch base, making the use of the reversing switch safer.

[0005] The technical solution adopted by this utility model to solve its technical problem is a dustproof reversing switch for automobiles, including an upper seat and a switch base. The upper end of the upper seat is provided with a sliding cavity that runs through the left and right sides. The switch base is slidably connected to the sliding cavity. The upper end of the switch base is provided with an operating part. The lower end of the switch base is provided with a switch triggering structure. The switch triggering structure includes a first inclined protrusion and a second inclined protrusion arranged front and rear. A first contact is located on the sliding path of the first inclined protrusion, and a second contact is located on the sliding path of the second inclined protrusion. The first inclined protrusion and the second inclined protrusion form a misaligned triggering of the corresponding first contact and second contact. The lower end of the switch base is also provided with a first limiting protrusion and a second limiting protrusion. When the second inclined protrusion triggers the second contact, the first limiting protrusion forms a limiting engagement with the first contact. When the first inclined protrusion triggers the first contact, the second limiting protrusion forms a limiting engagement with the second contact.

[0006] The advantages of the above technical solution are as follows: By using the first and second inclined protrusions to form a staggered triggering structure for the first and second contacts, compared with the staggered groove structure in the prior art, the triggering and engagement method between the switch base and the first and second contacts is changed without changing the installation height of the switch base. This reduces the overall thickness of the switch base. Furthermore, by designing the relative spacing between the first and second inclined protrusions, neither the first nor the second inclined protrusion can trigger the first and second contacts. Moreover, by using the above triggering method, a first and second limiting block of corresponding length can be formed on the lower end of the switch base, thereby effectively and reliably preventing excessive slippage of the switch base. Through the design of the above structure, the structure of the automotive built-in dustproof reversing switch is reasonable, effectively limiting the stroke of the switch base, making the use of the reversing switch safer, with more reasonable molding costs and lighter weight.

[0007] Furthermore, the lower end of the switch base is provided with a third inclined protrusion and a fourth inclined protrusion. The third inclined protrusion and the fourth inclined protrusion respectively cooperate with the first inclined protrusion and the second limiting protrusion or respectively cooperate with the second inclined protrusion and the first limiting protrusion. The third inclined protrusion and the fourth inclined protrusion are used to realize the automated assembly of the switch base and the upper base.

[0008] The advantages of the above technical solution are: by setting the third and fourth inclined protrusions, when the switch base is slidably installed along the left or right through opening of the sliding cavity, the installation of the first inclined protrusion, the second limiting protrusion or the second inclined protrusion, the first limiting protrusion and the corresponding first contact and second contact will not be obstructed, thus facilitating automated assembly.

[0009] Furthermore, the lower end of the switch base is provided with a first material reduction groove and a second material reduction groove at a distance from front to back. The first material reduction groove and the second material reduction groove are arranged through one side of the third inclined protrusion and the fourth inclined protrusion. The first inclined protrusion, the first limiting protrusion and the third inclined protrusion are located in the first material reduction groove, and the second inclined protrusion, the second limiting protrusion and the fourth inclined protrusion are located in the second material reduction groove.

[0010] The advantages of adopting the above technical solution are: the setting of the first and second material reduction grooves makes the forming of the first inclined protrusion, the second inclined protrusion, the third inclined protrusion, the fourth inclined protrusion, as well as the first limiting protrusion and the second limiting protrusion more reasonable, and also makes the forming cost of the switch base more reasonable and the weight lighter.

[0011] Furthermore, the upper surface of the switch base is also provided with a third material reduction groove, a fourth material reduction groove, and a fifth material reduction groove. The third material reduction groove corresponds to the first inclined protrusion, so the fourth material reduction groove corresponds to the second inclined protrusion, and the fifth material reduction groove corresponds to the first limiting protrusion or the second limiting protrusion.

[0012] The advantages of adopting the above technical solution are: by setting the third, fourth and fifth material reduction grooves, the molding cost of the switch base is more reasonable, the weight is lighter, and the structural design is more reasonable.

[0013] Furthermore, the sliding cavity has a sliding groove that runs through both sides at its root. The corresponding side of the switch base has a guide edge, and the upper side of the guide edge has multiple first sliding arc blocks spaced apart from each other. The outer side of the guide edge has multiple second sliding arc blocks spaced apart from each other. The first and second sliding arc blocks slide and contact with the sliding groove. The bottom of the guide edge also has a support protrusion, and the support protrusion is gapped relative to the bottom surface of the sliding cavity.

[0014] The advantages of adopting the above technical solution are: the guide slide edge, through the first sliding arc block, the second sliding arc block, and the supporting protrusion, achieves the purpose of making the switch seat slide smoothly left and right in the sliding cavity, and also makes the molding cost of the switch seat more reasonable.

[0015] Furthermore, the upper seat is provided with two through holes in the sliding cavity, and each through hole is provided with an anti-detachment protrusion. The first contact and the second contact are inserted into the through holes, and each of the first contact and the second contact is provided with a stop protrusion, which cooperates with the anti-detachment protrusion.

[0016] The advantages of the above technical solution are as follows: when the first contact and the second contact are installed in the corresponding through-holes by automated equipment, the stop protrusions on the first contact and the second contact will be stopped by the anti-disengagement protrusions in the corresponding through-holes, thereby preventing the first contact and the second contact from coming out and ensuring the reliability of the fit.

[0017] Furthermore, a positioning notch is provided at the bottom of the peripheral wall of the upper seat. The positioning notch cooperates with the positioning component to realize the automated assembly of the upper seat or the upper seat assembly and the lower seat assembly.

[0018] The advantages of adopting the above technical solution are: the setting of the positioning notch achieves the purpose of positioning the upper seat, thereby facilitating the assembly of the upper seat or upper seat component with the lower seat component by automated equipment.

Detailed Implementation

[0026] 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.

[0027] Please see Figures 1 to 6As shown, a dustproof reversing switch for automotive installation includes an upper seat 1 and a switch base 2. The upper end of the upper seat 1 has a sliding cavity 3 that extends horizontally. The switch base 2 is slidably connected to the sliding cavity 3. The upper end of the switch base 2 has an operating part 4, which is an operating port. The operating port can be formed by a ring surrounding the upper end of the upper seat 1. By actuating the operating part 4, the switch base 2 is slidably moved. The lower end of the switch base 2 has a switch triggering structure. More specifically, the switch triggering structure includes a first inclined protrusion 5 and a second inclined protrusion 6 arranged front and rear. The inclined surfaces of the first inclined protrusion 5 and the second inclined protrusion 6 are smoothly connected to the lower end of the switch base 2. The first contact 7 is located on the sliding path of the first inclined protrusion 5, and the second contact 8 is located on the sliding path of the second inclined protrusion 6. The first inclined protrusion 5 and the second inclined protrusion 6 are used to press down the first contact 7 and the second contact 8, thereby changing the contact mode of the corresponding contact piece on the base assembly by the first contact 7 and the second contact 8. The first inclined protrusion 5 and the second inclined protrusion 6 form a staggered trigger for the corresponding first contact 7 and second contact 8. That is, during the sliding process of the switch base 2, the triggering part of the first inclined protrusion 5 and the triggering part of the second inclined protrusion 6 are staggered. The lower end of the switch base 2 is also provided with a first limiting protrusion 9 and a second limiting protrusion 10. When the second inclined protrusion 6 triggers the second contact 8, the first limiting protrusion 9 forms a limiting engagement with the first contact 7. When the first inclined protrusion 5 triggers the first contact 7, the second limiting protrusion 10 forms a limiting engagement with the second contact 8.

[0028] In the above structure, by employing the first inclined protrusion 5 and the second inclined protrusion 6 to form a staggered triggering structure for the first contact 7 and the second contact 8, compared to the prior art which uses a staggered groove structure, the triggering and engagement method between the switch base 2 and the first contact 7 and the second contact 8 is changed. The lower end of the switch base 2 triggers the corresponding first contact 7 and second contact 8 only through the first inclined protrusion 5 and the second inclined protrusion 6. In this way, without changing the installation height of the switch base 2, the switch base 2 can maintain an effective distance from the bottom of the sliding cavity 3 by reducing the overall thickness. Furthermore, the above structure can also achieve this by using the first inclined protrusion 5 and the second inclined protrusion 6. The design of the left and right relative spacing allows the first inclined protrusion 5 and the second inclined protrusion 6 to achieve the purpose of not triggering the first contact 7 and the second contact 8. Moreover, by adopting the above-mentioned triggering method, the increased distance between the lower end of the switch base 2 and the bottom of the sliding cavity 3 allows the formation of a first limiting block 9 and a second limiting block 10 of corresponding length on the lower end of the switch base 2, thereby effectively and reliably preventing the excessive sliding of the switch base 2. Through the above structural design, the structure of the automotive built-in dustproof reversing switch is reasonable, effectively limiting the stroke of the switch base 2, making the use of the reversing switch safer, the molding cost more reasonable, and the weight lighter.

[0029] In this embodiment, the lower end of the switch base 2 is also provided with a third inclined protrusion 11 and a fourth inclined protrusion 12. The third inclined protrusion 11 and the fourth inclined protrusion 12 respectively cooperate with the first inclined protrusion 5 and the second limiting protrusion 10 or respectively cooperate with the second inclined protrusion 6 and the first limiting protrusion 9. The third inclined protrusion 11 and the fourth inclined protrusion 12 are used to realize the automated assembly of the switch base 2 and the upper base 1. In the above structure, by setting the third inclined protrusion 11 and the fourth inclined protrusion 12, when the switch base 2 is slidably installed along the left or right through opening of the sliding cavity 3, it can avoid the first inclined protrusion 5, the second limiting protrusion 10 or the second inclined protrusion 6, the first limiting protrusion 9 and the corresponding first contact 7 and second contact 8 from causing installation obstruction, thereby facilitating automated assembly.

[0030] In this embodiment, the first inclined protrusion 5 is positioned to the left of the second inclined protrusion 6, and the third inclined protrusion 11 is connected to the left side of the first inclined protrusion 5. The fourth inclined protrusion 12 is connected to the left side of the second limiting protrusion 10. The connection points between the third inclined protrusion 11 and the fourth inclined protrusion 12 and the lower end of the switch base 2 are both smoothly transitioned. The connection points between the third inclined protrusion 11 and the fourth inclined protrusion 12 and the first inclined protrusion 5 and the second limiting protrusion 10 are also smoothly transitioned. More specifically, the first limiting protrusion 9 and the second limiting protrusion 10 are both rectangular blocks, and the first inclined protrusion 5, the second inclined protrusion 6, the third inclined protrusion 11, and the fourth inclined protrusion 12 are all triangular inclined blocks.

[0031] In this embodiment, the lower end of the switch base 2 is provided with a first material reduction groove 13 and a second material reduction groove 14 at intervals. The first material reduction groove 13 and the second material reduction groove 14 are arranged through one side of the third inclined protrusion 11 and the fourth inclined protrusion 12. The first inclined protrusion 5, the first limiting protrusion 9, and the third inclined protrusion 11 are located in the first material reduction groove 13, and the second inclined protrusion 6, the second limiting protrusion 10, and the fourth inclined protrusion 12 are located in the second material reduction groove 14. In the above structure, the arrangement of the first material reduction groove 13 and the second material reduction groove 14 makes the forming of the first inclined protrusion 5, the second inclined protrusion 6, the third inclined protrusion 11, the fourth inclined protrusion 12, the first limiting protrusion 9, and the second limiting protrusion 10 more reasonable, and also makes the forming cost of the switch base 2 more reasonable and the weight lighter.

[0032] In this embodiment, the upper surface of the switch base 2 is also provided with a third material reduction groove 15, a fourth material reduction groove 16, and a fifth material reduction groove 17. The third material reduction groove 15 corresponds to the first inclined protrusion 5, the fourth material reduction groove 16 corresponds to the second inclined protrusion 6, and the fifth material reduction groove 17 corresponds to the first limiting protrusion 9 or the second limiting protrusion 10. In the above structure, by setting the third material reduction groove 15, the fourth material reduction groove 16, and the fifth material reduction groove 17, the molding cost of the switch base 2 is more reasonable, the weight is lighter, and the structural design is more reasonable. More specifically, since the third inclined protrusion 11 is connected to the left side of the first inclined protrusion 5, the third material reduction groove 15 will also correspond to the third inclined protrusion 11. Since the fourth inclined protrusion 12 is connected to the left side of the second limiting protrusion 10, the fifth material reduction groove 17 corresponds to the second limiting protrusion 10 and the fourth inclined protrusion 12.

[0033] In this embodiment, the sliding cavity 3 has two through-grooves 18 at its inner root. The corresponding side of the switch base 2 has a guide edge 19, and the upper side of the guide edge 10 has multiple first sliding arc blocks 20 spaced apart horizontally. The outer side of the guide edge 19 has multiple second sliding arc blocks 21 spaced apart horizontally. The first and second sliding arc blocks 20 and 21 slide in contact with the groove 18. The bottom of the guide edge 10 also has a supporting protrusion 22, which is positioned opposite the bottom surface of the sliding cavity 3. In this structure, the second sliding arc blocks 21 of the guide edge 19 will contact the inner walls of the two sides of the groove 18. The first contact 7 and the second... The two contacts 8, through the action of the switch base 2, cause the first sliding arc block 20 of the guide edge 19 to also form a contact fit with the upper inner wall surface of the slide groove 18. During the process of the first inclined protrusion 5 and the second inclined protrusion 6 engaging with the first contact 7 and the second contact 8, the support ridge 22 provides support for the switch base 2, thereby preventing the switch base 2 from swinging back and forth significantly. Therefore, the guide edge 19, through the first sliding arc block 20, the second sliding arc block 21, and the support ridge 22, achieves the purpose of making the switch base 2 slide smoothly left and right in the sliding cavity 3. Moreover, the thickness of the guide edge 19 does not need to match the width of the slide groove 18, which also makes the molding cost of the switch base 2 more reasonable.

[0034] In this example, the upper seat 1 has two through-holes 23 in the sliding cavity 3, and each through-hole 23 is provided with an anti-detachment protrusion 24. The first contact 7 and the second contact 8 are inserted through the through-holes 23. Each of the first contact 7 and the second contact 8 is provided with a stop protrusion 25. The stop protrusion 25 cooperates with the anti-detachment protrusion 24. In the above structure, when the first contact 7 and the second contact 8 are installed in the corresponding through-holes 23 by an automated device, the stop protrusion 25 on the first contact 7 and the second contact 8 will be stopped by the anti-detachment protrusion 24 in the corresponding through-hole 23, thereby preventing the first contact 7 and the second contact 8 from coming out and ensuring the reliability of the cooperation.

[0035] In this example, a positioning notch 26 is provided at the bottom of the peripheral wall of the upper seat 1. The positioning notch 26 cooperates with the positioning component to realize the automated assembly of the upper seat 1 or the upper seat component and the lower seat component. In the above structure, the positioning notch 26 achieves the purpose of positioning the upper seat 1, thereby facilitating the automated equipment to assemble the upper seat 1 or the upper seat component with the lower seat component.

[0036] In this embodiment, the device further includes a lower base assembly, which includes a lower base 27, a first stationary contact piece 28, a second stationary contact piece 29, and a movable contact piece 30. There is one first stationary contact piece 28 with two stationary contact ends. There are two second stationary contact pieces 29, which correspond to the corresponding stationary contact ends of the first stationary contact pieces 28. There are two movable contact pieces 30, with one movable contact piece 30 installed on each second stationary contact piece 29. The swing end of the movable contact piece 30 may or may not contact the corresponding stationary contact end of the first stationary contact piece 28. More specifically, when the first inclined protrusion 5 and the second inclined protrusion 6 trigger the first contact 7 and the second contact 8, the swing end of the movable contact piece 30 may contact the corresponding stationary contact end of the first stationary contact piece 28; otherwise, it may not contact the first contact 7.

[0037] In this embodiment, the lower base 27 is also provided with a third stationary contact piece 31. There are two third stationary contact pieces 31, and the two third stationary contact pieces 31 and the two stationary contact ends on the first stationary contact piece 28 are arranged vertically relative to the swing end of the corresponding moving contact piece 30.

[0038] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
