Description
本申請案係基於西元2012年1月5日申請之習知日本專利申請案第2012-000630號之優先權之利益，此日本專利申請案第2012-000630號之所有內容係合併列入參考。 The present application is based on the benefit of the priority of the Japanese Patent Application No. 2012-000630, filed Jan.
本發明係關於一種改良一車輛之一後部位之一備胎儲存部位之強度的技術。 The present invention relates to a technique for improving the strength of a spare tire storage portion of a rear portion of a vehicle.
於相關技藝中，各種汽車之後部位具有用以儲存一備胎之一儲存部位。舉例而言，用於備胎之儲存部位係依照備胎之一形狀於汽車之一後底板中形成一似環狀凹部位。 In the related art, various rear parts of the automobile have a storage portion for storing a spare tire. For example, the storage portion for the spare tire forms an annular concave portion in the rear bottom plate of one of the cars in accordance with one of the spare tire shapes.
此外，一車輛中之複數肋係自一備胎之一儲存位置之一中心部位徑向設於一備胎儲存部位之一底板上，藉此以增加其儲存部位之強度(剛性)(例如：參閱JP-A-2007-38839及JP-A-2009-96345)。 In addition, a plurality of ribs in a vehicle are radially disposed on a bottom plate of one of the spare tire storage locations from a central portion of one of the storage positions of a spare tire, thereby increasing the strength (rigidity) of the storage portion thereof (for example: See JP-A-2007-38839 and JP-A-2009-96345).
再者，於具有一拖鉤之一結構之一車輛中，此拖鉤係設於一備胎儲存部位之一後部位之下方，並且由拖鉤所輸入之部分載荷係藉由儲存部位所支承(例如：參閱JP-A-9-2336)。特別地，拖鉤所依附之一鉤架係延伸朝向車輛之一前側，並且鉤架係連接於備胎之一儲存位置之一中心部位與拖鉤間，備胎之一中心部位係固定至儲存位置之中心部位， 藉以對於輸入載荷進行支承。 Furthermore, in a vehicle having a structure of one of the tow hooks, the tow hook is disposed below a rear portion of a spare tire storage portion, and a part of the load input by the tow hook is supported by the storage portion. (Example: See JP-A-9-2336). In particular, one of the hook frames attached to the tow hook extends toward a front side of the vehicle, and the hook frame is connected between a central portion of one of the storage positions of the spare tire and the tow hook, and a central portion of the spare tire is fixed to the storage. The center of the location, Thereby supporting the input load.
此外，一種組態是經由JP-A-2007-38839及JP-A-2009-96345所揭露之圓緣與JP-A-9-2336所揭露之組態進行結合而得，其中，自拖鉤沿一縱向所輸入之載荷係可經由鉤架及圓緣而有效地傳送至一車輛前側之一元件。 In addition, a configuration is obtained by combining the round edge disclosed in JP-A-2007-38839 and JP-A-2009-96345 with the configuration disclosed in JP-A-9-2336, wherein the self-tapping The load input along a longitudinal direction can be efficiently transmitted to one of the components on the front side of the vehicle via the hook frame and the rounded edge.
附帶提出的是，近年來試圖對於一車體進行重量縮減以達到例如改進燃料消耗之目的，並且減少備胎儲存部位之一板厚已成為一種趨勢。 Incidentally, in recent years, attempts have been made to reduce the weight of a vehicle body to achieve, for example, an improvement in fuel consumption, and it has become a tendency to reduce the thickness of one of the spare tire storage portions.
於此方式下，藉由減少備胎儲存部位之板厚可達到車體重量的縮減。然而，即使利用所形成之複數圓緣仍無法確保其具有充足強度之問題，並且於進行拖拉時之輸入載荷容易造成儲存部位的變形。舉例而言，當因進行拖拉時輸入朝向車輛之後側之拉伸載荷時，由於在一車寬方向(側向)上之一壓縮應力係施加在延伸朝向於車輛前側之複數圓緣間之複數部位中，需注意的是於車寬方向上之複數圓緣間可能產生收縮且可能產生挫曲現象。再者，當進行朝向車輛前側之壓縮載荷之輸入時，由於壓縮應力是集中在一特定圓緣(延伸朝向於車輛前側、於車寬方向上之中心附近之一圓緣)，需注意的是在圓緣之一中間部位可能產生挫曲。也就是說，由於藉由減少備胎儲存部位之板厚容易造成儲存部位之變形或損壞，因此不易同時達到重量縮減及確保其強度。 In this way, the weight of the vehicle body can be reduced by reducing the thickness of the spare tire storage portion. However, even if the plurality of rounded edges formed are utilized, the problem of sufficient strength cannot be ensured, and the input load at the time of pulling is likely to cause deformation of the storage portion. For example, when a tensile load toward the rear side of the vehicle is input as the drag is performed, a compressive stress is applied to a plurality of round edges extending toward the front side of the vehicle due to a compressive stress in a vehicle width direction (lateral direction). In the part, it should be noted that there may be shrinkage between the plurality of round edges in the width direction of the vehicle and buckling may occur. Furthermore, when the input of the compressive load toward the front side of the vehicle is performed, since the compressive stress is concentrated on a specific round edge (an edge which is extended toward the front side of the vehicle in the vicinity of the center in the vehicle width direction), it is noted that A buckling may occur in the middle of one of the rounded edges. That is to say, since the deformation or damage of the storage portion is easily caused by reducing the thickness of the spare tire storage portion, it is difficult to simultaneously achieve weight reduction and ensure strength.
本發明係用於解決上述問題，並且本發明之一目的在於提供一種車輛的後體結構，藉此可抑制供一備胎所使用 之車輛之一後部位之一儲存部位中之載荷的局部集中。 The present invention is to solve the above problems, and an object of the present invention is to provide a rear body structure of a vehicle, whereby the use of a spare tire can be suppressed. A local concentration of the load in one of the storage locations of one of the rear portions of the vehicle.
本發明提出一種車輛的後體結構，其中，適合於儲存一備胎之一凹儲存部位係形成於車輛之一後部位之一底板中，並且一拖鉤係設於儲存部位之一下部位之一後側。儲存部位包括一底壁、一外周圍部位、一中心部位及一階級部位，其中，備胎之一輪胎部位係受外周圍部位所支承，中心部位係低於外周圍部位之一中心部位，備胎之一輪部位係儲存於中心部位中，階級部位係定義於外周圍部位與中心部位之間，複數圓緣之間形成有複數間隔且自中心部位徑向地延伸。拖鉤係經由一補強構件連接至儲存部位之中心部位。至少一部分之複數圓緣係自中心部位延伸朝向於車輛之一前側形成而於階級部位進行區分。 The invention provides a rear body structure of a vehicle, wherein a concave storage portion suitable for storing a spare tire is formed in one of the bottom portions of one of the rear portions of the vehicle, and one of the tow hooks is disposed at one of the lower portions of the storage portion. Back side. The storage part comprises a bottom wall, an outer surrounding part, a central part and a class part, wherein one tire part of the spare tire is supported by the outer surrounding part, and the central part is lower than a central part of the outer surrounding part, One wheel portion of the tire is stored in the central portion, and the class portion is defined between the outer peripheral portion and the central portion, and a plurality of intervals are formed between the plurality of round edges and extend radially from the central portion. The tow hook is connected to the central portion of the storage site via a reinforcing member. At least a portion of the plurality of rounded edges are formed from the center portion toward the front side of one of the vehicles to distinguish between the class portions.
部分之複數圓緣係於一徑向延伸至一外側以超過儲存部位之一邊緣部位。 A portion of the plurality of rounded edges extends radially to an outer side to extend beyond one of the storage locations.
根據本發明之一特點，由於複數圓緣間係徑向延伸於中心部位，延伸朝向於車輛前側之部分圓緣並非形成於階級部位之中且所形成之圓緣是可於階級部位進行區分，當朝向車輛後側之拉伸載荷自鉤施加於儲存部位時，由於藉由階級部位之操作可承受延伸朝向於車輛前側之圓緣間所產生之壓縮載荷，並且藉此可抑制圓緣間之挫曲。再者，當朝向車輛前側之壓縮載荷係自拖鉤施加至儲存部位時，由於輸入至車寬方向上之中心附近之圓緣的載荷係經由階級部位而傳送至圓緣且將載荷分佈至前側，如此可將載荷之集中抑制於一特定圓緣。 According to a feature of the present invention, since the plurality of round edges extend radially to the center portion, a portion of the round edge extending toward the front side of the vehicle is not formed in the class portion and the formed round edge is distinguishable in the class portion. When the tensile load toward the rear side of the vehicle is applied from the hook to the storage portion, since the operation of the class portion can withstand the compressive load generated between the round edges extending toward the front side of the vehicle, and thereby the inter-circle edge can be suppressed. Setback. Further, when the compressive load toward the front side of the vehicle is applied from the tow hook to the storage portion, the load transmitted to the round edge near the center in the vehicle width direction is transmitted to the round edge via the class portion and the load is distributed to the front side. Thus, the concentration of the load can be suppressed to a specific round edge.
此外，徑向延伸且設於儲存部位中之複數徑向圓 緣係經配置而可對於因拖拉所產生之載荷進行縱向上之分佈，並且藉由所形成之階級部位支承備胎，藉此可經由一相對簡單結構以確保儲存部位之強度。 In addition, a plurality of radial circles extending radially and disposed in the storage portion The rim is configured to provide a longitudinal distribution of the load due to the drag and to support the spare tire by the formed class portion, whereby the strength of the storage portion can be ensured via a relatively simple structure.
在此方式下，由於可經由一簡單組態以有效地抑制因拖拉載荷造成之儲存部位之變形及損壞，即使是減少備胎用之儲存部位之厚度下以達重量縮減下仍可確保充足強度，並且可容易同時達成車輛之重量縮減及儲存部位之強度之目的。 In this way, since the deformation and damage of the storage portion due to the drag load can be effectively suppressed through a simple configuration, sufficient strength can be ensured even if the thickness of the storage portion for the spare tire is reduced to achieve the weight reduction. And it is easy to achieve the purpose of reducing the weight of the vehicle and the strength of the storage portion at the same time.
根據本發明之一特點，由於圓緣係超過儲存部位之一邊緣部位且沿著一徑向延伸至外側，載荷易於集中之邊緣部位可藉由圓緣而強化，並且可抑制儲存部位之邊緣部位之變形及損壞。 According to a feature of the present invention, since the rounded edge extends beyond one of the edge portions of the storage portion and extends along a radial direction to the outer side, the edge portion where the load is easily concentrated can be reinforced by the rounded edge, and the edge portion of the storage portion can be suppressed. Deformation and damage.

如第1、2圖所示，儲存於一備胎3之一儲存部位4係形成於本實施例之一汽車(以下稱為一車輛1))之一後部位之一行李室之一底板2上。根據用於儲存備胎3之儲存部位4之配置下，依照備胎3之一形狀於底板2上形成一似環狀凹部位，並且似環狀凹部位係設於成對之側框架5、6間，側框架5、6係沿車輛之左側及右側之一縱向、於一橫元件7後側之底板2上而延伸，此橫元件7係側向地連接側框架5、6。 As shown in FIGS. 1 and 2, a storage portion 4 stored in a spare tire 3 is formed in one of the luggage compartments of one of the rear parts of the automobile (hereinafter referred to as a vehicle 1) of the present embodiment. on. According to the configuration for storing the storage portion 4 of the spare tire 3, an annular concave portion is formed on the bottom plate 2 according to one shape of the spare tire 3, and the annular concave portion is attached to the pair of side frames 5, Six, the side frames 5, 6 extend along the longitudinal direction of one of the left and right sides of the vehicle, on the bottom plate 2 on the rear side of a transverse element 7, which laterally connects the side frames 5, 6.
一螺栓10係直立於儲存部位4之一中心CL，並且於螺栓10通過備胎3之一中心孔之狀態下藉由一螺帽11予以固定，藉此將備胎3固定於儲存部位4之一內部位。 A bolt 10 is erected at a center CL of the storage portion 4, and is fixed by a nut 11 in a state where the bolt 10 passes through a center hole of the spare tire 3, thereby fixing the spare tire 3 to the storage portion 4. An internal bit.
一弧狀階級部位15設於儲存部位4之一底壁12上，使得以一凹形狀形成之一中心部位14比一外周圍部位13更向下。備胎3之一輪胎部位3a係受底壁12之外周圍部位13所支承，並且備胎3之一輪部位3b係可儲存於底壁12之中心部位14中。 An arcuate step portion 15 is provided on one of the bottom walls 12 of the storage portion 4 such that a central portion 14 is formed in a concave shape to be more downward than an outer peripheral portion 13. One tire portion 3a of the spare tire 3 is supported by the peripheral portion 13 outside the bottom wall 12, and one wheel portion 3b of the spare tire 3 can be stored in the central portion 14 of the bottom wall 12.
所設之一補強構件16係自螺栓10之固定位置延伸至位在儲存部位4之底壁12之一下表面上之後側位置之一端部位。此外，用於拖拉之一鉤17(拖鉤)係固定至補強構件16之一後端。 One of the reinforcing members 16 is provided to extend from a fixed position of the bolt 10 to a position at one end of the rear side position on the lower surface of one of the bottom walls 12 of the storage portion 4. Further, one of the hooks 17 (towing hooks) for pulling is fixed to the rear end of one of the reinforcing members 16.
所設之複數圓緣20、21、22之間形成有複數間隔，複數圓緣20、21、22係自中心部位14上之補強構件16之附近、於儲存部位4之底壁12上沿一徑向而向外延伸。儲存部 位4之底壁12是以數毫米程度而下凹形成圓緣20、21、22。再者，於本實施例中具有總共十一個圓緣20、21、22，在安裝空間之限制下，於圓緣中之三圓緣20、21之複數後端係沿一車寬方向(一側向)上之中心附近而結合為一體。 A plurality of intervals are formed between the plurality of round edges 20, 21, 22, and the plurality of round edges 20, 21, 22 are from the vicinity of the reinforcing member 16 on the central portion 14 and on the bottom wall 12 of the storage portion 4. Radially and outwardly. Storage department The bottom wall 12 of the bit 4 is recessed to a degree of a few millimeters to form the rounded edges 20, 21, 22. Furthermore, in the present embodiment, there are a total of eleven round edges 20, 21, 22, and under the restriction of the installation space, the plurality of rear ends of the three round edges 20, 21 in the round edge are along a vehicle width direction ( One side is joined to the center of the upper side and integrated into one.
特別地，本實施例中之於車寬方向上之中心附近所設之前側之複數(於本實施例中之五圓緣)圓緣20、21並非形成於階級部位15之中，並且所形成之圓緣20、21是以可於階級部位15進行區分。 In particular, the plural (in the present embodiment, the five-circle edge) round edges 20, 21 of the front side provided in the vicinity of the center in the vehicle width direction in this embodiment are not formed in the class portion 15, and are formed. The rounded edges 20, 21 are distinguishable by the class portion 15.
此外，於徑向上之圓緣20、22之外端係於徑向向外延伸超過儲存部位4之一邊緣部位25。 Furthermore, the outer ends of the rounded edges 20, 22 in the radial direction extend radially outward beyond one of the edge portions 25 of the storage portion 4.
根據上述組態可知，於車輛1中，由於自鉤17輸入至儲存部位4之拉伸及壓縮載荷可經由圓緣20、21而有效地分佈至前側，藉此以抑制載荷之局部集中。 According to the above configuration, in the vehicle 1, since the tensile and compressive loads input from the hook 17 to the storage portion 4 can be efficiently distributed to the front side via the round edges 20, 21, local concentration of the load can be suppressed.
於此相較於一比較例子(相關技藝之結構)，於比較例子具有本發明之上述實施例中所形成之延伸於階級部位15上之複數圓緣，於儲存部位4中之載荷動作之差異及本發明之效果將特別提出說明。 Compared with a comparative example (the structure of the related art), the comparative example has the difference of the load action in the storage portion 4 formed by the plurality of round edges formed on the step portion 15 formed in the above embodiment of the present invention. The effects of the present invention will be specifically described.
第3圖係為比較例子之一車輛30之一後體結構之一上視圖。 Figure 3 is a top view of one of the rear body structures of one of the vehicles 30 of the comparative example.
第3圖之比較例子之車輛30之一儲存部位4不同於上述本發明之實施例之儲存部位4之處在於定位於一中心部位14上之前側之圓緣20、21是形成於一階級部位15之中且於一車輛縱向連續形成以相交於階級部位15。再者，位在儲存部位4之前側之圓緣20、21係向前延伸至儲存部位4之一邊 緣部位25之後側且於縱向上具有較短的長度。於車輛30中，由於位在前側之圓緣21是形成於階級部位15之中，在安裝空間之限制下之圓緣21的數量減至四到二個。 The storage portion 4 of one of the vehicles 30 of the comparative example of Fig. 3 is different from the storage portion 4 of the above-described embodiment of the present invention in that the rounded edges 20, 21 positioned on the front side of a central portion 14 are formed in a class portion. 15 is formed continuously in the longitudinal direction of a vehicle to intersect the class portion 15. Furthermore, the round edges 20, 21 located on the front side of the storage portion 4 extend forward to one side of the storage portion 4. The edge portion 25 has a rear side and a shorter length in the longitudinal direction. In the vehicle 30, since the bead 21 on the front side is formed in the class portion 15, the number of the bead 21 under the restriction of the installation space is reduced to four or two.
於具有上述形狀之相關技藝之車輛30之儲存部位4中，當朝向車輛後側之拉伸載荷施加於鉤17時，此載荷係經由一補強構件16而施加於儲存部位4之中心部位14，相較於補強構件16之被定位在更前側之圓緣20、21係被拉動至車輛之後側。藉此，將兩圓緣21沿車寬方向移動朝向中心的力量係作用在圓緣21上，並且壓縮載荷係施加於圓緣20與圓緣21間。如果對於儲存部位4之一底壁12之板厚進行減少以達重量縮減的情況下，所需注意的是壓縮載荷可能不會受到支承，並且儲存部位4之底壁12係於圓緣20與圓緣21間、於中心部位14之前側受到沿車寬方向的壓縮而產生挫曲。 In the storage portion 4 of the vehicle 30 having the above-described related art, when a tensile load toward the rear side of the vehicle is applied to the hook 17, the load is applied to the central portion 14 of the storage portion 4 via a reinforcing member 16, The round edges 20, 21 of the reinforcing member 16 that are positioned on the front side are pulled to the rear side of the vehicle. Thereby, the force that moves the two rounded edges 21 in the vehicle width direction toward the center acts on the rounded edge 21, and the compressive load is applied between the rounded edge 20 and the rounded edge 21. If the thickness of the bottom wall 12 of one of the storage locations 4 is reduced to achieve weight reduction, it is noted that the compressive load may not be supported, and the bottom wall 12 of the storage portion 4 is tied to the bead 20 and The front edge of the center edge portion 14 between the round edges 21 is compressed in the vehicle width direction to cause buckling.
當所施加之壓縮載荷係自鉤17朝向車輛前側時，由於沿縱向延伸之圓緣20係於車寬方向之中心受到之補強構件16的壓迫，載荷係集中於圓緣20。因此，同樣在此一例子中，如果對於儲存部位4之底壁12之板厚進行減少以達重量縮減的情況下，所需注意的是圓緣20無法承受載荷且可能產生挫曲。在此方式下，由於在此相關技藝之結構中產生載荷之局部集中，並且由於在儲存部位4之底壁12之減少板厚之情況下進行載荷的拖拉是容易造成儲存部位4的變形，因此不易達到重量縮減。 When the applied compressive load is from the hook 17 toward the front side of the vehicle, since the rounded edge 20 extending in the longitudinal direction is pressed by the reinforcing member 16 at the center in the vehicle width direction, the load is concentrated on the rounded edge 20. Therefore, also in this example, if the thickness of the bottom wall 12 of the storage portion 4 is reduced to achieve weight reduction, it is noted that the bead 20 cannot bear the load and may cause buckling. In this manner, since the local concentration of the load is generated in the structure of the related art, and since the pulling of the load is performed in the case where the thickness of the bottom wall 12 of the storage portion 4 is reduced, the deformation of the storage portion 4 is easily caused. It is not easy to achieve weight reduction.
再者，由於在車寬方向之中心之圓緣20之一前端係向前延伸至儲存部位4之邊緣部位25之後側，壓縮載荷係 集中於圓緣20前側之儲存部位4之邊緣部位25的附近(第3圖中之“C”所示之一區域)，並且儲存部位4之邊緣部位25之附近區係易產生變形。 Furthermore, since one of the front ends of the bead 20 at the center of the vehicle width direction extends forward to the rear side of the edge portion 25 of the storage portion 4, the compression load is It is concentrated in the vicinity of the edge portion 25 of the storage portion 4 on the front side of the rounded edge 20 (one region shown by "C" in Fig. 3), and the vicinity of the edge portion 25 of the storage portion 4 is easily deformed.
另一方面，於本實施例中之儲存部位4，由於位在前側之自中心部位14延伸朝向車輛前側之圓緣20、21並非形成於階級部位15之中且所設置之圓緣20、21是可於階級部位15進行區分，階級部位15所具功能係相同於位在儲存部位4前側之一部位中略側向延伸之一圓緣。因此，當經由補強構件16而自鉤17施加朝向車輛後側之拉伸載荷時，藉由階級部位15之操作可承受圓緣20、21間所產生之壓縮載荷，並且可抑制圓緣20、21間之儲存部位4之底壁12之挫曲。 On the other hand, in the storage portion 4 in the present embodiment, the round edges 20, 21 extending from the center portion 14 toward the front side of the vehicle on the front side are not formed in the class portion 15 and the rounded edges 20, 21 are provided. It is possible to distinguish between the class parts 15 and the function of the class part 15 is the same as the one edge extending slightly laterally in one of the front sides of the storage part 4. Therefore, when the tensile load toward the rear side of the vehicle is applied from the hook 17 via the reinforcing member 16, the compressive load generated between the round edges 20, 21 can be withstood by the operation of the class portion 15, and the rounded edge 20 can be suppressed. The buckling of the bottom wall 12 of the 21 storage locations 4.
此外，當朝向車輛前側之拉伸載荷經由補強構件16而自鉤17輸入中心部位14，於車寬方向上之中心輸入至圓緣20之載荷係經由階級部位15而被傳送至複數圓緣21且被分佈至前側，藉此以抑制載荷集中於圓緣20。 Further, when the tensile load toward the front side of the vehicle is input from the hook 17 to the center portion 14 via the reinforcing member 16, the load input to the round edge 20 at the center in the vehicle width direction is transmitted to the plurality of round edges 21 via the class portion 15. And distributed to the front side, whereby the load is concentrated on the rounded edge 20.
再者，於本實施例中，由於在徑向上之圓緣20、21、22外側之端部係延伸至儲存部位4之邊緣部位25之外側，壓縮載荷並非集中於邊緣部位25，並且可抑制邊緣部位25之變形及損壞。 Furthermore, in the present embodiment, since the outer end portions of the outer edges 20, 21, 22 in the radial direction extend to the outer side of the edge portion 25 of the storage portion 4, the compressive load is not concentrated on the edge portion 25, and can be suppressed. Deformation and damage of the edge portion 25.
在此方式下，於本實施例之設於儲存部位4中之複數徑向圓緣20、21經配置而可利用階級部位15對於載荷進行分佈，並且所形成之階級部位15係用以儲存備胎3，藉此可經由一相對簡單結構以確保儲存部位4之強度。 In this manner, the plurality of radial beades 20, 21 provided in the storage portion 4 of the present embodiment are configured to distribute the load using the class portion 15, and the formed class portion 15 is used for storing The tire 3 can thereby ensure the strength of the storage site 4 via a relatively simple structure.
由於可經由一簡單組態以有效地抑制因拖拉使得 拉伸載荷或壓縮載荷自鉤17輸入至儲存部位4所造成之儲存部位4之變形及損壞，即使是減少儲存部位4之厚度下以達重量縮減下仍可確保充足強度，並且可容易同時達成車輛之重量縮減及儲存部位4之強度之目的。 Thanks to a simple configuration to effectively suppress dragging The deformation or damage of the tensile load or the compressive load from the hook 17 to the storage portion 4 caused by the storage portion 4 can ensure sufficient strength even when the thickness of the storage portion 4 is reduced, and can be easily achieved at the same time. The weight of the vehicle is reduced and the strength of the storage site 4 is used.
再者，本發明並不受上述實施例所限制。舉例而言，所安裝之圓緣20、21、22數量可依據儲存部位4之尺寸而改變。本發明可廣泛地應用在包括階級部位之一車輛，此階級部位係略沿側向而於備胎所用之儲存部位之底壁中延伸。 Further, the present invention is not limited by the above embodiments. For example, the number of rounded edges 20, 21, 22 installed may vary depending on the size of the storage site 4. The invention is broadly applicable to vehicles including one of the class locations that extend slightly laterally in the bottom wall of the storage location for the spare tire.
