Abstract

PURPOSE:To prevent a windshield supported by a cowl top from being broken by arranging a separation section which is separated up and back and forth when the front surface of the cowl top is subjected to a high impact load. CONSTITUTION:A separation section 4 is arranged at a center section of the right and left on a front surface of a cowl top ranging over an extended range on right and left. This separation section is designed to be easily broken when it is subjected to a high impact load allowing it to be separated up an down, and back and forth. The separation section is composed of a separation opening 41 ranging over the above said extended range on the front surface 12, a cover 43 covering the opening and fixed with bolts 42, and a break member 44 which connects the lower edge of the cover 43 the the lower edge of the front surface. On being subjected to a high impact load, the break member 44 is broken allowing the lower edge of the cover 43 and the lower edge of the opening 41 to be separated. This does not permit the impact load to be transmitted beyond the cover 43.

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a cowl top structure for automobiles, etc., in which a cowl top outer panel and a cowl top inner panel are connected in a pattern. To provide an improved system for preventing deformation caused by the external force from spreading to a windshield support part connected to the rear upper edge of the cowl top when an unexpected external force such as causing the cowl top acts on the front surface of the cowl top. 2. Description of the Related Art For example, in an automobile in which an engine is mounted in the front of a compartment, a cowl top is provided to receive the rear end of a cowling or bonnet that covers the engine compartment. This cowl top is formed into a thin plate with a closed cross-sectional shape that connects a cowl top outer panel with a substantially inverted I-shaped cross section and a cowl top inner panel with a U-shape, 15-shape, etc. cross-section in order to obtain the required torsional rigidity. There are many things that have been done. The upper rear edge of the cowl top is provided with a support portion that supports the windshield. However, the cowl top formed into a thin plate closed cross-sectional shape has a drawback in that if a large external force acts on a portion of the cowl top, the external force will spread to the entire cowl top, and the deformation caused by the external force will spread to the entire cowl top. The most unfavorable example where this drawback appears is (1+2t, Ir, etc.) where the front part of the heavy body is large (
When the windshield is crushed by the impact force and the engine etc. collides with the front of the cowl top, the deformation due to the impact force spreads to the support part that supports the intsole, causing the windshield to separate from the support part or be damaged. This is a case where the danger to the crew is increased and the danger to the crew is increased. From the perspective of ensuring rider safety, the spread of such danger must be prevented as much as possible. In order to prevent the spread of such danger, for example, as shown in Japanese Utility Model Application Publication No. 57-70980, a bead is formed on the lower side of the cowl top, and the upper part of the front surface is raised to a predetermined height. i! A cowl top structure has been proposed in which a portion zl1 is connected by a screw or the like that is sheared in the horizontal direction under a load of i'J. In such a cowl top structure, when the cowl top deforms horizontally only backwards, the separation part separates horizontally, the beat part is compressed, and the deformation of the cowl top due to external force then spreads to the upper edge. do not. However, in reality, the lower front edge of the cowl top is connected to the cabin floorboard or chassis via the front wall of the cabin, and the engine, etc. that collides with the front lower edge of the cowl top simultaneously connects to the front wall of the cabin. It is Kawadori that collides with it and bends it. Due to this concave bending of the front wall of the vehicle compartment, the front surface of the cowl top is pulled downward, and the earthen wall of the cowl top is then bent around its upper edge. On the other hand, the support part may be integrally extended from the rear edge of the cowl top upper surface in order to effectively ward off rain, or may be overlapped with the rear upper edge of the cowl top inner panel to further strengthen the support part. Together, they have a structure in which they are in '/S contact. Therefore, twisting of the front surface of the cowl top tends to spread to the support portion, and there remains a problem in preventing the spread of danger due to detachment or breakage of the windshield. [Problem to be Solved by the Invention] The present invention was invented under the above circumstances, and the problem to be solved is to avoid damage caused by an engine or the like to the front of the cowl top. The purpose of the present invention is to effectively prevent the expansion of dangers such as detachment and damage of the windshield supported by the cowl top. In order to solve the technical problem, the following technical measures have been taken: Namely, the front surface of the cowl top, which is formed by connecting a cowl top outer panel and a cowl top inner panel in a closed cross-sectional shape, has a thickness of more than a predetermined value. A separation part that separates in the vertical direction and front-rear direction when subjected to a high tJj impact load is provided over a predetermined range in the left and right width direction. In order to confine it to as small an area as possible, it is preferable to make the area behind the other object, such as the engine, which may collide with the cowl top, spread out laterally and slightly larger than the horizontal width of this other object. In order to form the separation part, for example, the front lower edge of the cowl top outer panel and the cowl I-knob inner panel may be omitted over a predetermined range, or the front surface of the cowl top may be covered with f[12 parts] over that range. However, the front surface of the cowl top can be opened up and down over a predetermined range, and a lid formed separately to cover the opening can be installed in such a way that it can be easily attached and detached. (If the cover is removed, devices such as a wiper motor can be easily installed inside the cowl top. It is only necessary to configure the tool so that it breaks or deforms due to an impact force exceeding a predetermined height (h) and loses its coupling function. When a fti collision occurs, a high impact load is applied backwards to the front of the cowl top, and the front wall of the passenger compartment connected to the front lower edge of the cowl top is bent concavely, causing the cowl top front lower edge to move downward. Therefore, the front lower edge of the cowl top receives Ih Qk forces both backward and downward at the same time.The front lower edge of the cowl top receives these impact forces, causing separation. These fh TA
When the force spreads, the front surface of the cowl top is divided into two parts from the 2nd and 11th parts, and the deformation of the front lower edge of the cowl top is not transmitted to the part above the divided part of the front surface of the cowl top. Due to the impact force of This is absorbed by bending this front portion backward at the bending portion formed at the connection portion between the front surface and the upper surface of the cowl top, and the upper surface of the cowl top is not torsionally deformed. Further, the impact force acting on the front lower edge of the cowl top is absorbed by bending the bent portion of the rear lower edge of the cowl 1-knob and the connecting portion between the cowl top inner panel and the cowl top inner panel. Therefore, even if the support part is reinforced at the rear upper edge of the cowl top inner panel, the above-mentioned (h
The deformation caused by the impact force does not affect the supporting parts. As described above, according to the cowl top structure for an automobile or the like according to the present invention, even if another object such as an engine collides with the front of the cowl top and the cowl top is deformed, the deformation is caused by the rear upper part of the cowl top. Since it does not affect the support part connected to the edge, the windshield A1 will not come off or be damaged.
It is possible to effectively prevent the spread of danger associated with this. [Description of Embodiments] Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a longitudinal cross-sectional view of one embodiment of the present invention, and FIG. 2 is a perspective view of the main part thereof. This cowl top is
A cowl top outer panel l and a cowl top inner panel 2 are connected to form a closed cross-sectional shape. The cowl top outer panel 1 includes a substantially horizontal upper surface 11, a front surface 12 extending substantially vertically downward from the front edge of the upper surface 11, and a front surface 12 extending substantially vertically downward from the front edge of the upper surface 11.
A connecting lip portion 13 extends forward from the lower edge of the connecting lip portion 13, and a support portion 3 extends obliquely upward from the rear edge of the upper surface 11 in a crank shape. The cowl top inner panel 2 also has a rear surface 21 with a substantially doglegged cross section with the middle protruding rearward, a lower surface 22 that extends forward from the lower edge of the rear surface 22 approximately horizontally, and a lower surface 22 extending approximately rearward from the upper edge of the rear surface 21. It has an extended connecting lip portion 23. 1. The lip portion 13 of the cowl top outer panel 1 is overlapped with the front edge of the lower surface 22 of the cowl top inner panel 2, and is firmly connected by spot welding or the like at appropriate intervals. In addition, the lip portion 23 of the cowl top inner panel 2
are placed on one example of a substantially horizontal portion of the support portion 3, and are connected by spot welding or the like at appropriate intervals. The middle part of the front surface 12 in the left and right direction is easily damaged by a high fJ+i impact load of a predetermined value or more over a range slightly expanded laterally and laterally than the left and right width of the engine behind the engine (not shown). Separation portions 1 are provided that separate in the vertical direction and in the IIF rear direction. This separation part 4 completely covers a minute opening 41 that opens over the range of the front surface 12 and this opening -i1, and is secured to both left and right edges of this opening 41 by, for example, six bolts 42. and ] - Meng 4 firmly fixed to the edge
3, a J-shaped connector which normally connects the lower edge of the lid 43 and the lower part of the front surface 12, and easily breaks when the 11:1 surface receives the high impact load; For example, it consists of a breaking member 44 made of a tapping screw. The opening 41
The length in the vertical direction is slightly smaller than the length of this front surface 12. In addition, an upper edge knob portion of the vehicle interior front wall 5 is connected to the front lower edge of the cowl top outer panel 1 and overlapped from below at the joint between the knob portion 13 and the lower surface 22 of the cowl top inner panel 2. , are firmly connected by spot welding, etc. The symbol 6 is a gasket made of an elastic material such as rubber. According to the automobile cowl top structure configured in this way, when another object such as an engine collides with the separation part 4 of the front surface 12 of the cowl top and the front wall 5 of the vehicle interior due to an accident, the rearward facing As the Takayama air pressure is applied, the front wall 5 of the vehicle compartment connected to the front lower edge of the cowl top is bent backwards, causing the front lower edge of the cowl top to move downward.
Pull down aggressively. Therefore, the front lower edge of the cowl top receives impact forces both backward and downward at the same time. Cowl top +'+ii +T+i 12 minutes i'i
j1 section 4 is broken due to the fact that its 9 fortune 11 tools 44 are hit by high impact carts in two directions, backward and forward.
1j1 between the lower edge of 3 and the lower edge of the opening 41
1, and the deformation of the front lower edge of the cowl top is less transmitted to the portion 1 than to the lid 43 of the separating portion 4 of the cowl top 1iij surface 12. Therefore, the upper surface 11 of the cowl top outer panel 1 is not deformed by these iii impact forces, and the support portion 3 continuous to the rear edge of this upper surface 11 is also not deformed. The impact force acting on the portion above the lid 43 of the separation section 4 of the front surface 12 is applied to the front surface 1 of the cowl top.
This is absorbed by bending the portion of the front surface 12 above the lid 43 backward at the bent portion formed at the connection between the cowl top 2 and the top surface 11, and the top surface II of the cowl top is not torsionally deformed. . In addition, the impact force acting on the front lower edge of the cowl top is applied to the bent portion formed at the connection between the rear edge of the lower surface 22 of the cowl 1 and the knob inner panel 2 and the rear surface 21, the bent portion at the middle height of the rear surface 21, and Upper edge of rear surface 21 and lip portion 23
This is absorbed by bending the bent portion formed at the connecting portion with the inner angle in the direction of opening or closing the included angle, and bending and deforming the lower surface 22 and rear surface 21 of the cowl top inner panel 2 in the east chamber 6. Ru. Therefore, the deformation of the cowl inner panel 2 due to the impact force does not spread to the support g33. In this way, according to the above-mentioned cowl top structure of an automobile, etc., even if another object such as an engine collides with the front surface of the cowl top and the cowl top is deformed, the deformation will occur at the rear of the cowl top. Since this does not affect the support part 3 connected to the edge, the windshield does not come off or the windshield breaks, and the danger associated with this can be effectively prevented from spreading. Further, the front surface 12 of the cowl top is opened wide vertically over a predetermined range, and a separately formed cup 43 is attached around the opening 41 using bolts 42.
and a separation tool 44 consisting of a self-tapping screw, the M2C can be easily removed by unscrewing these bolts 42 and separation tool 44, and by removing the lid 43, it can be inserted into the cowl top (not shown). Another advantage is that devices such as wiper motors can be easily installed. Of course, the present invention is not limited to the above-mentioned embodiment. For example, the separation section 4 is formed in front of the lip section 13 of the cowl top outer panel l and the lower surface 22 of the cowl top inner panel 2, as described above. The spot/8 contact with the edge may be omitted over a predetermined range in the left-right direction, and the blue color may be formed continuously or intermittently in the left-right direction on the front surface 12 over the predetermined range in the left-right direction.
