Description

Technical Field

[0001] This application relates to the technical field of electrical appliance life test devices, and particularly to an electrical appliance life test device applicable to rocker switches. Background Art

[0002] Electrical switches are components for controlling the opening and closing of electrical appliances. Before leaving the factory, they usually need to undergo aging life tests. The aging life test of the switch component requires the opening and closing operations of the switch to be completed within a specified number of cyclic opening and closing times.

[0003] Currently, the common electrical switch structures on the market include rotary type, touch type, and rocker type. For electrical appliances with rocker switches, in their aging life tests, there are those that are opened and closed manually, and there are also special test devices designed to improve efficiency. However, currently, whether carried out manually or using test equipment, only one-to-one switch life tests can be achieved. If multiple electrical appliance switch life tests need to be carried out, only manual labor or test equipment can be increased, which will undoubtedly greatly increase the manufacturing cost. Utility Model Content

[0004] In order to simultaneously carry out the life tests of multiple electrical appliance switches in one test device, this application provides an electrical appliance life test device applicable to rocker switches.

[0005] The electrical appliance life test device applicable to rocker switches provided by this application adopts the following technical solutions:

[0006] An electrical appliance life test device applicable to rocker switches, comprising:

[0007] A workbench;

[0008] At least two test stations arranged at intervals on the workbench;

[0009] A driving mechanism, the driving mechanism is connected to the workbench; and

[0010] A pressing mechanism, connected to the driving mechanism and located on one side of a number of test stations, the pressing mechanism includes a pressing portion that abuts against the rocker switch of the electrical appliance to be tested;

[0011] Wherein, the pressing mechanism is driven by the driving mechanism to reciprocate along the arrangement direction of the test stations and forces the pressing portion to toggle the rocker switch to achieve opening and closing.

[0012] By adopting the above technical solution, multiple electrical appliances to be tested can be correspondingly clamped and limited at the test stations. The test stations are arranged at intervals. The pressing mechanism is driven by the driving mechanism to reciprocate along the arrangement direction of the test stations. During the process, the pressing part in the pressing mechanism squeezes the rocker switch of the electrical appliance to be tested during the reciprocating motion to realize the opening and closing operations. Furthermore, a test device can simultaneously perform the rocker switch life test of multiple electrical appliances to be tested, improving production efficiency and reducing production costs at the same time.

[0013] Preferably, the pressing mechanism includes:

[0014] A first fixed seat, which is arranged on the workbench;

[0015] A second fixed seat, which is arranged on the workbench and has a certain distance from the second fixed seat;

[0016] A transmission assembly, which is driven by the driving mechanism to reciprocate between the first fixed seat and the second fixed seat; and

[0017] A transmission rod, which is connected to both sides of the transmission assembly;

[0018] Wherein, the pressing part is connected to the transmission rod and corresponds to the test stations one by one.

[0019] By adopting the above technical solution, the pressing part is arranged on the transmission rod, and the length of the transmission rod can be changed according to the number of electrical appliances to be tested. During the reciprocating motion with the transmission assembly, the pressing part can synchronously realize the opening and closing operations of the rocker switches of multiple electrical appliances to be tested.

[0020] Preferably, the transmission assembly includes:

[0021] A guide rod, which connects the first fixed seat and the second fixed seat;

[0022] Two spaced-apart limit plates, which are slidably connected to the guide rod, and the transmission rod is connected to the limit plates; and

[0023] A cam, which is connected to the driving mechanism, and the cam is placed between the two limit plates;

[0024] Wherein, the cam has an outer peripheral track surface, and the limit plates are always in contact with the outer peripheral track surface. When the cam is driven by the driving mechanism to rotate, the outer peripheral track surface squeezes the two limit plates to force the two transmission rods to reciprocate between the first fixed seat and the second fixed seat.

[0025] By adopting the above technical solution, the rotation of the cam squeezes the two limit plates to realize the reciprocating motion of the entire transmission assembly. Since the outer peripheral track surface of the cam can be set according to requirements, rapid execution during the opening and closing operations can be achieved during the reciprocating motion. A slow-speed sliding section can be set before the opening and closing operations, and the opening and closing operation paths can be set more flexibly according to test requirements.

[0026] Preferably, the transmission assembly includes a guide sleeve slidably connected to the guide rod, and the limit plate is connected to the guide sleeve.

[0027] By adopting the above technical solution, the setting of the guide sleeve can make the entire reciprocating motion more stable, and at the same time, it has stronger guiding performance during the sliding process with the guide rod.

[0028] Preferably, the driving mechanism includes:

[0029] A driving member connected to the lower part of the workbench;

[0030] A dial block driven to rotate by the driving member;

[0031] A sprocket; and

[0032] A transmission shaft, and the transmission shaft is connected to the pressing mechanism;

[0033] Wherein, the rotation of the dial block can intermittently drive the sprocket to rotate.

[0034] By adopting the above technical solution, the dial block rotates driven by the driving member. The sprocket has a plurality of tooth grooves formed at intervals due to its own structural characteristics. The dial block can intermittently drive the sprocket to rotate during the cooperation with the sprocket. The sprocket is connected to the pressing mechanism through the transmission shaft, and then the reciprocating motion of the pressing mechanism also acts intermittently, giving a certain response time for the start and stop of the electrical appliance when the rocker switch of the electrical appliance under test is operating, and more realistically simulating the test data during the use process.

[0035] Preferably, the test station includes:

[0036] A base provided on the workbench; and

[0037] A limit seat slidably connected to the base, and the limit seat has a limit area for accommodating the electrical appliance under test.

[0038] By adopting the above technical solution, the electrical appliance under test is clamped and limited within the limit area. The relative sliding of the limit seat and the base can adjust the vertical limit height of the electrical appliance under test and the matching accuracy between the electrical appliance under test and the pressing part, which is convenient for debugging and adjustment.

[0039] Preferably, the test station further includes a plurality of limit members, and one end of the limit member extends into the limit area.

[0040] By adopting the above technical solution, the limiting member realizes the pressing of the electrical appliance to be tested, and the number and connection positions of the limiting members on the limiting seat can be adjusted according to the shapes of different electrical appliances to be tested, improving the flexibility during clamping and limiting.

[0041] Preferably, the base can slide on the workbench closer to / away from the pressing mechanism.

[0042] By adopting the above technical solution, the cooperation accuracy between the rocker switch and the pressing part of the electrical appliance to be tested can be further debugged and adjusted.

[0043] Preferably, the pressing part has a guiding arc surface that abuts against the rocker switch.

[0044] By adopting the above technical solution, when the pressing part makes a reciprocating motion, the guiding arc surface can quickly and smoothly squeeze and push the rocker switch to rotate, improving the stability of the test.

[0045] Preferably, it further includes a counting module for recording the test progress.

[0046] By adopting the above technical solution, during the life test, the number of opening and closing cycles of the rocker switch of each electrical appliance to be tested is carried out according to the standard, and the counting module can record the number of opening and closing cycles of the rocker switch for easy identification after reaching the number of opening and closing cycles.

[0047] In summary, the present application includes at least one of the following beneficial technical effects:

[0048] 1. The reciprocating motion of the transmission rods connected to both sides of the transmission assembly is realized through the cam transmission form, and then the pressing part connected to the transmission rods makes a reciprocating motion. Combining the setting of multiple test stations for clamping and limiting the electrical appliances to be tested, the number and positions of the pressing parts correspond to the test stations one by one. Thus, a test device can synchronously carry out the life test of the rocker switches of multiple electrical appliances to be tested, improving the test efficiency and reducing the production and manufacturing costs;

[0049] 2. The sprocket is driven by the dial block to drive the cam to rotate intermittently in a mechanical transmission form, which better reduces the device cost and more realistically simulates the response of the electrical appliance to be tested after the rocker switch is opened and closed under normal conditions;

[0050] 3. The sliding connection of the base on the workbench in the test station, the sliding connection between the limiting seat and the base, combined with the connection of the limiting members, makes the operation more convenient during the debugging process of the cooperation between the electrical appliance to be tested and the pressing part.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items. Embodiment 1

[0063] Figure 1 With Figure 2 The structure of an electrical life test device applicable to a rocker switch of the present application is shown, where the electrical appliance 5 to be tested can be any electrical appliance in the form of a rocker switch 51, such as a hair dryer, a small fan, a hot air comb, a hair straightener, etc. Of course, during the test process, the electrical appliance 5 to be tested can be a whole machine clamping test or a component clamping test, and the test is carried out according to the occupied space and the required standard.

[0064] This test device specifically includes a workbench 1 and a driving mechanism 3, a pressing mechanism 4 and a plurality of test stations installed on the workbench 1. The electrical appliance 5 to be tested is limited to the test station. The driving mechanism 3 is installed below the workbench 1 and is connected to the pressing mechanism 4. The pressing mechanism 4 is driven by the driving mechanism 3 to perform a reciprocating motion along the arrangement direction of the test stations, and during the reciprocating motion, the rocker switch 51 of the electrical appliance 5 to be tested is opened and closed.

[0065] In this embodiment, there are two test stations respectively located on both sides of the pressing mechanism 4, and each test station correspondingly clamps and limits one electrical appliance 5 to be tested. The pressing mechanism 4 includes a first fixing seat 41, a second fixing seat 42, a transmission component and a transmission rod 46. There is a certain distance between the first fixing seat 41 and the second fixing seat 42. The transmission component is placed between the first fixing seat 41 and the second fixing seat 42 and can slide reciprocally between the first fixing seat 41 and the second fixing seat 42.

[0066] The transmission component includes two guide rods 43, a guide sleeve 45 slidably connected to the guide rods 43, a limiting plate 44 connecting the guide sleeve 45, and a cam 48. The two ends of the guide rod 43 are respectively connected to the first fixing seat 41 and the second fixing seat 42. The guide sleeve 45 is arranged on the guide rod 43. The limiting plate 44 is fixed to the guide sleeve 45 and there is a fixed distance between the two limiting plates 44. The cam 48 is placed between the two limiting plates 44 and the outer peripheral surface of the cam 48 always abuts against the two limiting plates 44. In addition, the cam 48 is also connected to the driving mechanism 3 and can be driven by the driving mechanism 3 to rotate. The rotation of the cam 48 squeezes the two limiting plates 44 to realize the reciprocating motion of the entire transmission component between the first fixing seat 41 and the second fixing seat 42.

[0067] Further, the transmission rod 46 has two ends respectively corresponding to and connected to one of the limiting plates 44, and the length and thickness of the transmission rod 46 are adjusted according to the installation position and quantity of the test stations on the workbench 1. The pressing mechanism 4 further includes a number of pressing parts 47 corresponding to the quantity and position of the test stations. The pressing parts 47 are connected to the limiting rod and extend from one side of the limiting rod towards the test stations. The pressing parts 47 can act on the rocker switch 51 of the electrical appliance 5 to be tested. Through the reciprocating movement of the transmission assembly, the transmission rod 46 is driven to move, and then the opening and closing operations of the rocker switch 51 are realized through the pressing parts 47.

[0068] Refer to Figure 3 , the driving mechanism 3 includes a driving member 31. The driving member 31 is preferably a driving motor. The output shaft of the driving member 31 is connected with a dial block 32. The dial block 32 includes an end extending horizontally outwards. The driving mechanism 3 further includes a transmission shaft 34 rotatably connected to the workbench 1. The two ends of the transmission shaft 34 extend outwards from both sides of the workbench 1 respectively. One end of the transmission shaft 34 is connected with a cam 48, and the other end of the transmission shaft 34 is connected with a sprocket 33. The sprocket 33 has a plurality of teeth circumferentially distributed. Tooth grooves are formed between adjacent teeth. When the dial block 32 is driven to rotate by the driving member 31, the end portion can intermittently enter the tooth grooves and push the sprocket 33 to rotate intermittently, and then drive the cam 48 to rotate intermittently, so as to realize the switching between the start and the close of the rocker switch 51 with a certain time interval, which is convenient to give sufficient response time when the electrical appliance 5 to be tested starts and closes.

[0069] Refer to jointly Figure 4 and Figure 5 , the test station 2 includes a base 21 and a limiting seat 22 installed on the base 21. The limiting seat 22 is generally concave and has a limiting area 221. The whole or part of the electrical appliance 5 to be tested can be placed in the limiting area 221. A plurality of limiting members 24 are further connected to the limiting seat 22. The limiting members 24 can extend their ends into the limiting area 221 through clamping or threaded connection to realize the clamping and positioning of the electrical appliance 5 to be tested. Of course, the quantity and arrangement mode of the limiting members 24 can also be arbitrarily combined according to the shape of the electrical appliance 5 to be tested, and can be applicable to the clamping and positioning of different electrical appliances.

[0070] The base 21 includes a bottom plate 212 and side plates 211 connected thereto. The limiting seat 22 is connected to the side plates 211 and is slidably connected to the bottom of the workbench 1 to adjust the matching position between the electrical appliance 5 to be tested and the pressing part 47. Specifically, two guiding blocks 23 arranged at intervals are provided on the workbench 1. The bottom plate 212 is placed between the two guiding blocks 23 to realize sliding guidance. After the bottom plate 212 completes the position adjustment relative to the workbench 1, the bottom plate 212 is fixed to the workbench 1 through fasteners.

[0071] At the same time, from Figure 4The structure of the pressing part 47 is also shown. The pressing part 47 has a guiding arc surface 471 at its outer edge. The guiding arc surface 471 can be in contact and cooperation with the rocker switch 51. A common rocker switch 51 has an arc-shaped groove in the middle, and the guiding arc surface 471 protrudes outward and can be partially fitted with the groove, so as to more smoothly realize the opening and closing operation of the rocker switch 51.

[0072] Refer to jointly Figure 2 With Figure 6 , the distance between the rotation center of the cam 48 and one of the limiting plates 44 is defined as H1, and the distance between the rotation center of the cam 48 and the other limiting plate 44 is defined as H2. The outer peripheral surface of the cam 48 is a designed outer peripheral track surface 481. When H1 is less than H2, as shown in Figure 2 , at this time, the entire pressing mechanism 4 moves to the right as indicated by the arrow; when H1 is greater than H2, as shown in Figure 6 , at this time, the entire pressing mechanism 4 moves to the left as indicated by the arrow.

[0073] This test device further includes a counting module. The counting module includes two proximity switches 6, a counter and a control unit arranged on the workbench 1. The two proximity switches 6 respectively detect the positions of the two limiting plates 44, and are respectively used to receive the opening and closing times of the rocker switch 51 of the left-side electrical appliance 5 to be tested and the opening and closing times of the rocker switch 51 of the left-side electrical appliance 5 to be tested. The counter has two connections corresponding to one of the proximity switches 6 and the control unit respectively, and is mainly used to receive the emission signal of the corresponding proximity switch 6 and record the test progress. The test progress is the number of opening and closing times that the preset rocker switch 51 has not yet performed.

[0074] During the test process, the corresponding opening and closing times are pre-entered into the two counters. When the rocker switch plate 211 on one side reaches the opening and closing times, the value of the corresponding counter is displayed as zero, and the electrical appliance 5 to be tested on the corresponding side can be removed. To improve the test efficiency, the opening and closing times standards of the electrical appliances 5 to be tested on the same side of the transmission component are often the same, and all the electrical appliances 5 to be tested on one side of the transmission component can be removed after reaching the preset opening and closing times.

[0075] The reciprocating motion of the pressing part 47 drives the cam 48 to rotate through the driving part 31. The cam 48 squeezes the two limiting plates 44 to realize the reciprocating motion of the two transmission rods 46, and further drives the pressing part 47 to slide reciprocally relative to the rocker switch 51 to realize opening and closing. Embodiment 2

[0076] Refer to Figure 7 , an electrical appliance life test device applicable to a rocker switch, which is different from Embodiment 1 in that two pressing parts 47 are arranged on the same transmission rod 46, and then two test stations 2 are arranged on the same side of the transmission component, and the tests of four electrical appliances 5 to be tested can be carried out synchronously. Embodiment 3

[0077] Refer to Figure 8 An electrical life test device applicable to a rocker switch, which is different from the second embodiment in that pressing portions 47 are connected to both sides of the same transmission rod 46, and test stations 2 are provided on both sides of the corresponding transmission rod 46, and tests on six electrical appliances 5 to be tested can be carried out synchronously.

[0078] Of course, as the length of the transmission rod 46 increases, more tests on the electrical appliances 5 to be tested can be synchronously realized, and it is not limited to the setting modes of the second embodiment or the third embodiment.

[0079] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
