Problems solved by technology

[0006] In the conventional hood latch device, since the bottom of the striker entry passage of the bottom plate bears most of the closing movement force (closing energy) of the striker, an excessive load is concentrated on the bottom, and the bottom plate is easily warped and deformed. , the relative position of the latch and the ratchet is shifted, sometimes resulting in poor closing and opening of the hood
[0007] In Patent Document 1, a separate reinforcement member is attached to the bottom of the striker entry passage, but in a vehicle (especially an SUV type vehicle) using a large and heavy hood, the movement force due to the closing of the striker increases dramatically. , so it is difficult to prevent the warping and deformation of the bottom plate

Embodiment Construction

[0035] One embodiment of the present invention will be described based on the drawings. figure 1 The front of the hood latch device 10 for an engine hood of this invention is shown. In most vehicles, the engine room is disposed on the front side of the vehicle, and an end (base end) of a typical hood (not shown) covering the engine room is equiaxially fixed to the vehicle body by a hinge. The hood latch device 10 includes a latch unit 11 fixed to the front end of the vehicle body, and a striker 12 fixed to the front end (rotational end) of the hood.

[0036] The latch unit 11 includes a metal bottom plate 13 . Bottom plate 13 is stamping molding product, as Figure 1 ~ Figure 3 As shown, a central plate 13a and left and right fixing plates 13b are provided. A striker entry passage 14 is formed in the upper center of the center plate 13a. The striker entry passage 14 is in the shape of a longitudinal U, with an opening 14a at the top and a bottom wall 14b at the bottom. Af...

Abstract

The present invention provides a hood latch. In order to distribute and receive the increased closing movement force of the striker (12), the latch unit (11) is provided with: a latch (17) that rotates from the unlocked position beyond the latch position to overrotation by engagement with the striker (12) position; and a ratchet (19) that keeps the latch (17) engaged with the striker by engaging the latch (17) returned to the latched position from the over-rotated position by the elastic force of the latch spring (20). The latch unit (11) is provided with a plurality of receiving members, and the plurality of receiving members contact the latch (17) when the latch (17) reaches an over-rotation position, thereby receiving the over-rotation force of the latch (17) . The plurality of receiving members are dispersedly arranged in two or more quadrants among four quadrants divided by a vertical line (B) and a horizontal line (C) passing through the rotation center of the latch shaft (16).

Description

technical field [0001] The present invention relates to a latch device for a hood (hood), and more particularly, to a hood latch device with improved strength. Background technique [0002] As in Patent Document 1, a conventional hood latch device includes a striker attached to a hood, and a latch unit attached to a vehicle body and engaged with the striker. A latch engaged with the striker and a ratchet engaged with the latch to maintain the engagement between the latch and the striker are fixed to the shaft on the bottom plate of the latch unit. A striker entry passage is provided on the bottom plate. The entry passage of the striker is in the shape of a bottomed U with an open upper part. [0003] When the engine hood is closed, the striker moves downward, enters the striker entry passage, and abuts against the striker engagement groove of the latch. By this abutment, the latch over-rotates from the unlocked position beyond the latched position against the elastic forc...
