Description
本發明係關於一種用於評估雨刷品質之系統；特別是關於一種可利用雨刷擺動時的振動量作為評估依據的用於評估雨刷品質之系統。 The present invention relates to a system for evaluating the quality of a wiper; and more particularly to a system for evaluating the quality of a wiper as a basis for evaluating the amount of vibration when the wiper is swung.
雨刷(如：傳統型、複合式或無骨等型式)為汽車的重要零組件之一，藉由雨刷反覆擺動，可即時清除汽車擋風玻璃上有礙行車視線的物質(如：雨水、灰塵或泥土等)，以維行車安全。 Wipers (such as: traditional, composite or boneless) are one of the important components of the car. With the wiper repeatedly swinging, the material on the windshield that hinders the sight of the car (such as rain, dust or Mud, etc., to maintain safety.
其中，一般雨刷作動時，有可能會因為雨刷與玻璃間的摩擦阻力，而產生噪音、抖動或顫振等不良因素，進一步影響行車過程，該不良因素的最大原因初步可推測應為雨刷的膠條材料所致。 Among them, when the general wiper is actuated, there may be adverse factors such as noise, jitter or flutter due to the frictional resistance between the wiper and the glass, which further affects the driving process.

The range of values.
如第6b圖所示，當無骨式雨刷〝下刷〞時，可將受測的第1~17個雨刷按其主觀評價分數(介於2.5~4.5)大小從左至右依序標示其客觀評價指標值的最大值曲線、平均值曲線、最大值曲線(介於110.00~120.00)，再依據該主觀評價分數劃分不同客觀評價分數(如：2.5、3、4、4.5)對應該客觀評價指標值的範圍。 As shown in Figure 6b, when the boneless wiper is brushed under the armpit, the first to the 17th wipers can be labeled from the left to the right according to their subjective evaluation scores (between 2.5 and 4.5). The maximum value curve, the average curve, and the maximum value curve (between 110.00 and 120.00) of the evaluation index value, and then the objective evaluation scores (eg, 2.5, 3, 4, 4.5) are classified according to the subjective evaluation score. The range of values.
綜上，如4a、4b、5a、5b、6a、6b圖所示，上述三種類型雨刷之主客觀評價標準可如上表一所示，此表之值可儲存於該處理模組4中，用於後續測試其他雨刷時的標準，如：用於無骨式雨刷時，若上刷、 下刷的總振動量皆為112(介於客觀評價分數4~4.5之間)，該處理模組4可依據該總振動量將該分級指標轉換為3；另，用於複合式雨刷時，若上刷、下刷的總振動量分別為116.5、113.5(介於客觀評價分數3.5~4之間)，該處理模組4可依據該總振動量將該分級指標轉換為3.5；又，用於傳統式雨刷時，若上刷、下刷的總振動量分別為122、126(介於客觀評價分數2~2.5之間)，該處理模組4可依據該總振動量將該分級指標轉換為2；其餘分級指標可依此類推，在此容不贅述。 In summary, as shown in FIG. 4a, 4b, 5a, 5b, 6a, and 6b, the subjective objective evaluation criteria of the above three types of wipers can be as shown in Table 1, and the values of the table can be stored in the processing module 4. Standards for subsequent testing of other wipers, such as when used for boneless wipers, if brushed, The total vibration amount of the lower brush is 112 (between objective evaluation scores of 4 and 4.5), and the processing module 4 can convert the classification index into 3 according to the total vibration amount; and when used for the composite wiper, If the total vibration amount of the upper brush and the lower brush is 116.5 and 113.5 respectively (between the objective evaluation scores of 3.5 and 4), the processing module 4 can convert the classification index to 3.5 according to the total vibration amount; In the conventional wiper, if the total vibration amount of the upper brush and the lower brush is 122 and 126 respectively (between objective evaluation scores of 2 and 2.5), the processing module 4 can convert the classification index according to the total vibration amount. It is 2; the rest of the grading indicators can be deduced by analogy, and will not be described here.
此外，該分級指標的劃分方式除可定為客觀評價分數(多種分數)外，亦可定為高、中、低等3種客觀評價等級，或可定為優(GO)、劣(NO GO)等2種客觀評價結果。如第7圖所示，(a)顯示不同傳統式雨刷之下刷的總振動量介於121.8~122.4之間，對照如上表一的數值範圍，可用以轉換該分級指標為〝4分〞、〝高〞或〝優(GO)〞(如(c)、(e)、(g)所示)；同理，(b)顯示不同傳統式雨刷之上刷的總振動量介於120.2~120.8之間，對照如上表一的數值範圍，可用以轉換該分級指標為〝3分〞、〝中〞或〝優(GO)〞(如(d)、(f)、(h)所示)。如第8圖所示，(a)顯示不同複合式雨刷之下刷的總振動量介於116.8~117.6之間，對照如上表一的數值範圍，可用以轉換該分級指標為〝3分〞、〝中〞或〝優(GO)〞(如(c)、(e)、(g)所示)；同理，(b)顯示不同複合式雨刷之上刷的總振動量介於119~120之間，對照如上表一的數值範圍，可用以轉換該分級指標為〝2、3分〞、〝低、中〞或〝優(GO)、劣(NO GO)〞(如(d)、(f)、(h)所示)。如第9圖所示，(a)顯示不同無骨式雨刷之下刷的總振動量介於114.6~115.2之間，對照如上表一的數值範圍，可用以轉換該分級指標為〝4分〞、〝高〞或〝優(GO)〞(如(c)、(e)、(g)所示)；同理，(b)顯示不同無骨式雨刷之上刷的總振動量介於114~115.5之間，對照如上表一的數值範圍，可用以轉換該分級指標為〝4分〞、〝高〞或〝優(GO)〞(如(d)、(f)、(h)所示)。 In addition, the classification of the grading indicators can be determined as objective evaluation scores (multiple scores), and can also be classified into three objective evaluation grades: high, medium, and low, or can be rated as excellent (GO) or bad (NO GO). ) Two kinds of objective evaluation results. As shown in Figure 7, (a) shows that the total vibration of the brush under different traditional wipers is between 121.8~122.4. Compared with the numerical range shown in Table 1 above, it can be used to convert the grading index to 〝4 minutes. 〝高〞 or 〝优(GO)〞 (as shown in (c), (e), (g)); similarly, (b) shows that the total vibration of the brush on different traditional wipers is between 120.2~120.8 Between the numerical ranges of Table 1 above, it can be used to convert the grading index to 〝3, 〝 or GO (GO) 〞 (as shown in (d), (f), (h)). As shown in Figure 8, (a) shows that the total vibration of the brush under different composite wipers is between 116.8 and 117.6. Compared with the numerical range shown in Table 1 above, it can be used to convert the grading index to 〝3 minutes. 〝中〞 or 〝优(GO)〞 (as shown in (c), (e), (g)); similarly, (b) shows that the total vibration of the brush on different composite wipers is between 119~120 Between the above and the numerical range of Table 1 above, it can be used to convert the grading index to 〝2, 3, 〝, 〞, 〝 or 〝 (GO), 劣 (NO GO) 〞 (such as (d), ( f), (h)). As shown in Figure 9, (a) shows that the total vibration of the brush under different boneless wipers is between 114.6 and 115.2. Compared with the numerical range shown in Table 1 above, it can be used to convert the grading index to 〝4 minutes. 〝高〞 or 〝优(GO)〞 (as shown in (c), (e), (g)); similarly, (b) shows that the total vibration of the brush on different boneless wipers is between 114 and 115.5 Between the numerical ranges of Table 1 above, it can be used to convert the grading index to 〝4, 〝 or 〝 (GO) 〞 (as shown in (d), (f), (h)).
